Do-it-yourself well drilling rig is made according to the free drawings presented below. Taking into account the purchase of all components, the cost of a home-made mini drilling rig for water will be 15-20% of a similar finished unit.
This diagram shows the main working units of the MGBU, which you can make according to our drawings.
Racks for the frame on the drilling rig are made of DN40 pipe, wall thickness 4mm. "Wings" for the slider - from DU50, thickness 4mm. If not with a 4mm wall, take 3.5mm. Download drawings for a do-it-yourself water drilling rig:
The drilling swivel and drilling rods are recommended to be purchased ready-made at first. In the manufacture of these parts, the accuracy of processing is very important, since the load on these nodes is large. We do not recommend making a swivel from improvised means. One slightest inaccuracy - and it will fail.
If you decide to order a swivel from a turner, you will need to find a qualified specialist, and preferably with modern CNC machines. Swivel and locks require strictly defined types of steel. For locks - 45 steel. For a swivel - 40X. Download a drawing of a homemade drilling swivel:
Attention! Private traders will not do high-quality hardening! After hardening, grinding is required. Use HDTV hardening, but this is an expensive procedure.
You can save on the purchase of ready-made nodes, but it will take a lot of time to find a suitable master. But it's worth it - homemade parts are much cheaper than purchased ones. To get started, purchase parts for samples. Turners work better when they have drawings and templates on hand.
If you have factory samples, it will be much easier to check the quality of work. For example, if a turner made drill rods (locks), then you take factory and home-made parts and screw them together to check the quality of the thread. Match must be 100%!
Don't buy delivery parts. This is necessary so as not to buy a marriage - this, unfortunately, happens. And most importantly - if you order delivery from afar, you can wait more than one month.
We advise you to make a trapezoid thread on drill rods - it is no worse than a conical one, but if you then order turners, then it is more difficult to make a conical thread.
If you make or buy locks for drill rods separately, then take simple seam pipes for rods if you drill no deeper than 30 meters (3.5 mm thick and an inner diameter of at least 40 mm). But a professional welder must weld the locks to the pipes! In vertical drilling, the loads are large.
For drilling deeper than 30 meters, only thick-walled pipes (with a wall of 5-6 mm) should be taken. Thin rods are not suitable for great depths - they will tear. Download drawing of locks for drill rods:
A simple drill is easy to make on your own. A drill is made from ordinary steel. If you decide to make it from alloyed, then keep in mind - it is difficult to weld! We need a welder. If there are a lot of stones at the drilling site, then buy special drills from firms that are adapted for solid soils. The higher the price, the harder the alloys on the drills and the stronger the drills themselves.

VIDEO In the manufacture of a mini drilling rig, the RA-1000 winch is used. You can take another, but preferably with a carrying capacity of at least 1 ton (or better, more). Some drillers put on two winches, one electric and the second mechanical. In the case of a wedge of the drill string, it helps a lot.
To facilitate the work, it is advisable to buy and connect two remotes: one reverse and move the engine, the other to the winch. This will save a lot of energy.
A gear motor for a home-made mini drilling rig will be required at 60-70 rpm, with a power of 2.2 kW. Weaker won't fit. If you use more powerful, you will need a generator, since it will not be possible to connect to a voltage of 220 volts. Recommended for hydrodrilling motor-reducer models: 3MP 31.5 / 3MP 40 / 3MP 50.
1. Purchase of drill rods and swivel (please note that the parts have the same thread, or use an adapter). To begin with, you don’t need to buy a lot, focus on a depth of 30 meters.
2. Purchase of a motor - gearbox. These purchases take a long time and there are often delays that are beyond your control, so it's best to buy in advance.
3. Making a frame and a drill. When making a frame, it is desirable to have a motor, swivel and winch on hand, since all this must be mounted on the frame. It is also problematic to make a carriage without a motor on your own, since the mounts for different motors may differ.
4. We buy the remaining components of the mini drilling rig after installing the main components on the frame.

It is recommended to start drilling for water from shallow depths in order to gain at least a little experience. Experience in vertical drilling is the most important! Water well drilling can only be learned through practice. Learn to avoid the wedge of the drill string. Beginners, due to inexperience, often "catch a wedge" and lose their drill rods. Sometimes the drill jams so much that it is impossible to pull it out even with a crane, the structure simply comes off (usually at the welding points).
Mistakes are expensive - an expensive tool is lost. Therefore, in hydrodrilling it is impossible to force events and immediately make deep wells. Approach this matter responsibly and carefully. Read literature and books about water wells. This work requires a lot of knowledge that cannot be conveyed in a nutshell, so self-education is a must.
When performing wells for water, as with any production process, performers strive to increase productivity as well as the efficiency of the process. Regarding the mentioned process, this is an increase in the speed of drilling a hole and optimization of unproductive losses in auxiliary operations. The first factor can be improved by softening the rocks if water is supplied to the working area.It will also help to increase the survivability of the drilling tool as a result of its intensive cooling and lubrication, especially if the fluid is a clay solution with antifriction additives. Here there is a contradiction between the rotational movement of the drill string and the stationary position of the fluid supply device. It can be solved if a swivel for a small drilling rig is used.
Fig.1. Drilling swivels for MGBU, on the right - self-made, on the left - in industrial design
As can be seen from Fig. 1 (left), this product consists of several simple parts:
top and bottom flanges;
internal partitions with grooves for sealing rings in the amount of 2 pieces;
a body made from scraps of a thick-walled pipe;
metal bar;
The following standard parts are used:
Obviously, such a unit can be made with your own hands if you have access to turning work, you just need to make a drawing or sketch of each part.
Various design solutions are possible with the use of stuffing box seals, other types of bearings, etc., which provide the main purpose of the assembly - interrupting the rotational movement of the drill string and supplying water, air or mud inside it.
This node is an intermediate link between the hoist making translational movement, the sleeve for supplying liquid or gas and the drill string performing rotational movement. The second end of the supply hose is connected to a pump or column for supplying the working composition.
Fig.2. Various modifications of swivels for drilling with flushing solutions
The body of the industrial swivel is made of cast iron or steel, depending on the calculated dynamic and static loads on the assembly. It provides filling and drain holes, as well as a viewing window to control the oil level in it - at high loads, a large amount of heat is generated in the mechanism. A mandatory element is a breather to relieve pressure when the swivel becomes very hot during operation. The bearing is selected based on the working conditions in the thrust version, since the loads from the drill string are very significant, they increase as its height increases.
A general idea of the designs and modifications of swivels for drilling water wells is shown in the drawing in Fig.2. Of course, they are unsuitable for do-it-yourself execution, but the drawing gives an idea of the applied principles for the design of products for this purpose.
Fig.3. Scheme of a drilling swivel for self-production
The schematic drawing of Fig. 3, in terms of ease of execution, makes it possible to make the assembly with your own hands, you may have to coordinate the dimensions according to the dimensions of the installation and the drilling tool.
Mini - do-it-yourself water drilling rigs have a design feature that consists in transferring all axial loads through the swivel. This happens both during the drilling process and when lifting the working tool. In addition, this assembly is exposed to the active action of abrasive materials when pumping the flushing solution.
Given the difficult operating conditions of the unit, materials for its manufacture by one's own hands should be selected with great care, based on the following considerations:
manufacturing in a home workshop is impossible without the use of welding, therefore, it is necessary to select metal of steel grades with high or normal weldability, which involves the use of low-carbon materials;
the swivel of a mini drilling rig works in direct contact with a composition with strong abrasive properties, which implies rapid wear of the contact surfaces, which determines the use of a material with the ability to resist wear;
during the drilling process, this unit experiences significant mechanical loads, since it is a transmission link for them, therefore, materials are needed that can carry them.
Based on the totality of requirements, it is possible to propose the use of steel grades 13GS, 17GS or 17G1S-U. With this carbon content, these materials weld well. The presence of manganese (G) in the composition of the metal determines its properties such as increased wear resistance and the ability to self-harden under the influence of abrasive media. And in combination with an alloying additive in the form of silicon (C), it determines the sufficient strength characteristics of the material. These steel grades were developed as a structural material for a wide range of purposes, and it should not be difficult to find it for the manufacture of parts.
The part drawing must contain all the details of the required tolerances and treatments that will ensure the long-term performance of the assembly, taking into account the performance characteristics of purchased products, including seals and bearings. The best way to avoid mistakes is to coordinate the drawing with an experienced designer.
A self-made drilling machine, and even more so with the possibility of high-quality flushing of the trunk, can not only facilitate the resolution of issues in your area. This is a direct way to organizing your own business based on investments made in equipment.
Based on the information obtained from this article, showing accuracy and ingenuity, it is likely that a self-made mini drilling rig, including a swivel, will work for a long time and reliably. I wish you success!

In order to install a water well drilling rig, you can use the services of qualified specialists, but, unfortunately, not everyone can spend a round sum of money on this. In some cases, installation by professionals is not possible due to certain conditions on the site. Then it remains only to assemble the equipment with your own hands, and then with knowledge in this area and at least a little experience.
To have an idea of what a drilling rig is, you should consider some of its types:
Small-sized equipment of small sizes of shock-rope type;
Screw machine that performs work without flushing wells;
Rotary drill, additionally flushing wells with the removal of rocks to the surface of the soil.
Such equipment is used most often, and in the conditions of small private territories, mini-installations are common, in which the shock-rope system is used.
Usually, MGBU consist of drills of standard diameters. The control of such equipment occurs through a block for regulating the load, as well as including different modes of engine operation.To lift the bar, a winch is used, which makes it possible to withstand loads up to 4 tons.
Small popular models carry out drilling to a depth of 70 meters. Very often, manufacturers can manufacture equipment for the required customer order.
At the same time, drilling equipment is able to work not only vertically, but also to drill at a certain angle.
Different types of structures can work with:
Electricity;
diesel fuel;
Pneumatic equipment;
Hydraulics.
The small dimensions allow the use of minimal human resources and convenient transportation of the unit. This explains the popularity of this type of drilling equipment.
This technique is in demand and is often used in private households. Its convenience and portability make the model popular among summer residents and owners of private houses.
This is not surprising, because it has its advantages:
Drilling equipment is easily transported, its installation is characterized by simple preparation and easy installation;
Equipment and improvised materials can be purchased at any time, due to the wide range and availability;
At the same time, the technique can be used to create a foundation and other construction work;
The construction does not require a large number of maintenance personnel;
The equipment is mobile and has compact dimensions, so it is suitable even for a small area;
The system can be powered by a generator. With all the positive qualities, the structure, moreover, is affordable. If desired, a drill for installation poles, like other parts, can be made on your own.
The drilling rig consists of aboveground and underground parts connected to each other.
Aboveground part includes:
drilling rig;
Equipment for drilling in the ground part;
Equipment for descent and ascent;
Drive unit;
drilling mud system.
Towers are mast and tower and are made of rolled steel or pipes. The structure of the tower tower includes: a balcony, a gate, goats, a platform, screeds, stairs, belts.
In turn, the mast tower is single-supported and the most common - double-supported.
The main elements of the mast: sections, fire escape, gantry, ladders (tunnel and mid-flight), extensions, balcony, belt for protection, sub-crown block frame.
The main characteristics of the tower are its height, load capacity, capacity to install pipes of different sizes, as well as the dimensions of the base, weight and size of the candle. The higher the setting, the deeper drilling is possible.
As a rule, any installation includes the main components. Drilling mechanisms include: auger, winch and hoist, hydraulic rotator - drilling gearbox. Power engineering can consist of internal combustion engines, it can be any motor - electric or hydraulic motor.
Devices with gas, liquid or mixed cleaning agents - swivel, pipes, mud pump, hoses.
In addition, the installation is equipped with a monitoring and measuring system consisting of various sensors, a control system and equipment designed to contain water emissions. In ICU, as a rule, elements of smaller diameters are used.
The manual assembly of the UKB uses precise drawings and detailed instructions.
For work you will need:
Rope for suspension of the cartridge;
Base for fastening in the form of a frame;
Winch and motor.
The scheme is implemented in the following way:
First, a collapsible frame is assembled. In a separate order, the parts of the impact cartridge and the bailer are connected in order to remove the soil.
To make loosening the earth more productive, jagged protrusions are used at the bottom of the glass. In the upper part it is necessary to make holes for attaching the rope.
The bailer is necessary for cleaning the face. She may be self-made.
The electric drive device, in turn, will help to significantly save time, and work, at the same time, will be more efficient. In general, the building is a hollow square shape.
Its main elements are:
frame;
Winch;
Boer;
Special drilling hoses;
Reducer;
A swivel that rotates the drill string.
All parts, the rack and the support are connected by welding, after which the electric motor and platform are fixed, which will simultaneously move along the tunnel of the iron constructor. If it is decided that a hydraulic pile driver will be used for drilling, you can make a hydraulic gearbox yourself.
The swivel provides the rotational movement that makes the drilling rig work.
According to its structure, it consists of simple elements:
Housing, which can be made from thick-walled pipe scraps;
metal rod;
2 partitions for sealing rings;
Flanges - top and bottom.
The fixture uses an o-ring and ball bearings.
With the ability to use a lathe and the presence of a diagram, a node for an MKBU can be made independently.
For do-it-yourself manufacturing, some features of the operation of the mechanism should be taken into account:
Materials, including steel for home-made performance, must be selected with high weldability;
Since the device is subject to rapid wear, materials with resistance to mechanical and abrasive effects should be taken for the case.
Otherwise, you must strictly follow the installation diagram.
VIDEO Drilling equipment for various needs is used everywhere, but as the most popular models for autonomous operation, compact modifications of the MCU continue to be in the first place. This is understandable - they are mobile, convenient to use, do not require the involvement of a large number of service personnel, and in addition, they are highly efficient.
Drilling rigs differ in their design due to the choice of different methods of creating a well. For example, an impact drill breaks up the soil with a special weight tied to a pyramidal support frame. But a rotating drill is a much more complex structure, but it is much easier to make a deepening of the required size in the soil with its help. By type of construction can be divided into several categories:
Percussion installations. The design is represented by a frame with a pyramidal base, to which a cable with a projectile (bailer) is securely attached. The principle of operation of such an installation is trivially simple: the load is lowered and raised as many times as it takes to create a hole of the required depth in the soil.
screw installations. Drilling is carried out using an auger that breaks through the ground according to the principle of rotation.At the same time, the recess dug during the drilling process is not washed out.
Attention! Keep in mind that drilling rigs of this type are a design too complex to be created by one's own hands: most of its functional elements are almost impossible to create without the appropriate skills and tools.
Rotors. Rotary structures work on the principle of hydraulics.
Manual designs of rotary type. These installations are considered the simplest to a greater extent for the reason that they do not have an engine in their design. Accordingly, the process of creating a well in the soil is carried out manually, which requires considerable physical costs. That is why such manual designs are very rarely used.
Undoubtedly, a drilling rig for creating a water well has a number of some advantages. These include:
Acceptable cost. It is noted that the factory design for drilling a water well in most cases costs much more than the one that was made by hand.
Compact and light weight design.
The technical characteristics of a hand-made drilling rig, as it turned out, are in no way inferior to factory-made units.
Ease of installation. Homemade drilling rigs are very easy to mount and dismantle.
In general, the technology for assembling various drilling rigs is almost the same (and this will be discussed a little later), but the working tool for structures of different types is fundamentally different. Therefore, to begin with, one should consider the manufacturing technology of the main mechanism (drill) for different designs, and only after that proceed directly to the creation of the main frame and the working elements attached to it.
So, we will consider in detail the most commonly used drilling rigs (installation with a “glass” and auger rig).
Drilling rig with "cartridge" uses the so-called "cartridge" ("glass") as the main working mechanism. If you want to make it yourself, then you only need a piece of pipe with a diameter of about 1 m. When creating a suitable base frame for such a drilling rig, the dimensions of the “cartridge” are taken into account without fail. The “cartridge” itself must have not only impressive dimensions, but also considerable weight for efficient drilling of the soil.
If you do not want to give the edges of the "chuck" a triangular shape, make sure that they are sharp (sharpen them if necessary).
We will fasten the "glass" with a cable, so it is necessary to make several holes on the load (in the upper part). We fasten the cable and then we hook it to the pre-prepared frame. Please note that the length of the cable must be such that the “cartridge” can fall down and rise up completely freely.
Screw installation uses a drill as a working working mechanism. For its manufacture, an ordinary metal pipe is also quite suitable. Make a screw thread on the top of the pipe, and an auger-type drill on the bottom (the most convenient drill length is about 2 m).
Advice. 2-3 turns on the drill will be enough to create a water well of medium depth.
A pair of knives must be attached to the ends of the drill using a welding machine: they must be located in such a way that during the drilling process they sink into the soil at a certain angle.
To make the design convenient to use, weld a part of a metal pipe (about 1.5-2 m long) to the tee. The tee itself must be equipped with a screw thread inside.
Separately, it should be said about the swivel, which is used in drilling rigs as a compensator against the movable part of the installation (drill) and the fixed part that supplies water.The device of this part is quite simple: a pair of flanges, partitions with sealing rubber rings, the body itself (made from a piece of metal pipe) and a metal bar.
It should be noted that this part can be made independently only if you have turning experience and the ability to make technical drawings.
So, the working mechanism of the drilling rig is prepared, now you can proceed directly to the assembly of the entire structure. Please note that you will need some tools for work: an electric drill, a grinder, a welding machine, as well as a galvanized pipe, a squeegee and a plumbing cross. Consider the process of assembling the structure step by step:
We prepare pipe sections to create the basis of the drilling rig. They will need to be fixed in a spur and a cross. At the ends of the pipe sections, cut the threads a couple of centimeters deep.
Weld pre-pointed metal plates to the ends of the metal pieces (such an installation will allow a continuous supply of water).
In order to supply water to the installation, connect a pump hose to one of the sections of the cross.
We connect the prepared parts to the threaded connections. We weld a metal piece with a tip to the bottom of the main pipe.
We proceed to collect the basis of the installation from a square profile. We connect metal supports to the main rack by welding.
We attach the engine and platform to the profile. The profile itself must be attached to the main rack in such a way that it moves freely along it.
The power of the engine will be regulated using a gearbox, to the shaft of which a flange must be attached. We attach another one to it, and lay a rubber washer between the flanges.
It remains to carry out the last step - to check the water supply. It must run smoothly.
This concludes our consideration of the technology for creating a drilling rig for water supply at home. Good luck!
