In detail: baler kyrgyzstan DIY repair from a real master for the site my.housecope.com.
The baler Kyrgyzstan is designed to collect cut grass and straw on flat fields. The release of equipment lasted from 1960 to 1992. The machine is equipped with a drum material collector, it is connected to agricultural machinery with a stern PTO shaft (rotation speed 540 rpm). Universal and row-crop tractors MTZ-80/82, YuMZ-6 or LTZ-60AB can be used as a tractor.
The pick-up Kyrgyzstan consists of a series of bolted assemblies:
cardan transmission;
main gearbox;
compression chambers;
a piston with a crank mechanism installed inside the chamber;
drum pick-up of material;
wheeled chassis;
knitting machine and packing machine;
drawbar.
The machine is based on a welded tubular frame on which the axle is rigidly mounted. Wheels with pneumatic tires are located on the hubs. There is a brake on the right side, which is activated when the pick-up is connected to the tractor. The mechanisms are driven by a cardan shaft connected to the power take-off shaft on the tractor. The kinematic diagram includes a safety clutch. Additionally, there is a stud that shears off when the torque threshold is exceeded.
The machine has a flywheel that reduces the uneven rotation of the nodes. A crank mechanism is installed on the output shaft of the camshaft gearbox, which is used to drive the piston of the bale chamber.
There is also an additional bevel gear pair, the torque from which is fed to a separate cardan gear. The unit is used to drive the pick-up drum and strapping mechanism.

The hay collected by the drum is fed into the press chamber, where it is compressed by the forward movement of the piston. On the side surfaces of the chamber there are special devices that keep the material compressed during the idle movement of the piston. The degree of compaction is adjusted with a regulator that smoothly changes the cross-section of the inlet channel. The compressed mass gradually turns the measuring wheel, which is responsible for turning on the knitting machine. Activation is performed at each full revolution.
The formed bale is bound with steel wire or special twine made of synthetic fiber. The type of binding material is determined by the design of the knitting unit. A ratchet mechanism is installed in the assembly design, which is installed on the same axis with a gear wheel and a cam. The rotation of the elements is responsible for the supply of the knitting needles to the apparatus and the return of the mechanism to its original position.
The bonded briquette is pushed outward and then onto a metal tray. The bales are then moved to the ground and loaded onto a trailer or truck.
A feature of the technical characteristics of the pick-up is the ability to work in a stationary position. A prerequisite is the removal of the clamping lattice from the cavity of the receiving channel. Hay or straw is fed by hand with a pitchfork. The scope of delivery included a special remote switch that made it possible to stop the engine being near the equipment.
The baler is not equipped with hydraulics and electrical systems. At night, the illumination of the working area is carried out by a stern headlight installed on the tractor. Only 2 red triangular reflectors can be installed on the pick-up.
Description of machine parameters:
capture width - 1650 mm;
installation width during transportation - 2500 mm;
pick-up weight - 1600 kg;
estimated maximum productivity - up to 13 tons of hay per 1 hour of work;
pressing density - up to 200 kg / m³.
Brief instructions for setting up baler assemblies Kyrgyzstan:
The operating instructions contain a number of recommendations:
Long-sleeved clothing is prohibited. Hair needs to be removed under the headdress.
Before starting, make sure that the connection between the propeller shaft and the protective cover is secure.
The operator must not leave the tractor cab without disconnecting the PTO shaft.
When working, it is unacceptable for people to be on the pick-up body.
Be careful when adjusting the knives as the mechanism can be twisted.
Before starting work, fill the knitting machine magazine with coils of twine or wire. The instructions for feeding the material are marked on the plates installed on the cover of the machine.
In the intervals between shifts, it is required to lubricate the rubbing elements and tighten the threaded connections. The list of works is indicated in the technical documentation.
Routine maintenance should be performed every 60 hours.
Kyrgyzstan pick-up malfunctions include:
There are no new cars on sale, since more than 25 years have passed since the end of production. Over the years of production, the plant has collected more than 100 thousand copies of the pick-up, many of which are still in operation. The cost of equipment in the secondary market starts from 80 thousand rubles. For 150-180 thousand rubles, you can purchase a pick-up in good technical condition. The rental price is negotiable, the owners are not officially announced. The PT-165 machine has a similar design, but the cost of used equipment starts at 400 thousand rubles.
Some time after leaving the field and starting work baler Kyrgyzstan bends needles piston, and this happens despite the fact that they have been aligned. Why does this happen and how can you fix this problem on your own with a minimum cost of money and time? Let's try to understand this issue in detail.
In construction baler Kyrgyzstan there are several safety devices at once, which are designed to protect the knitting machine under high loads:
Knitting machine drive safety device
Needle guard
Cassette safety knife
Thus, the correct operation of the Kyrgyzstan baler will depend on the good technical condition and correct adjustment of each of these three devices.
If baler Kyrgyzstan bends needles, the cause of this problem is most likely that the needle safety device does not work. The safety stop itself is necessary in order to avoid deformation of the needles at the moment when they remain in the bale chamber. And such a deformation can easily occur when the safety pin is cut.
The fact is that the safety pin is cut off when overloads occur, after which the supply of rotation to the knitting machine stops. Therefore, if the safety catch fails, the needles in the baling chamber may be bent by the piston. This problem can be corrected by carrying out a series of adjustments to the mechanisms.
First, the gap between the stop and the connecting rod must be adjusted. As a rule, it should not exceed 2 millimeters. In addition, you need to check the condition of the bar on which the stop hits. Its surface should be intact, without dents or chips. After carrying out these actions, during overloads, the flywheel hairpin will only be cut off.
By the way, in order to baler flywheel shear pin Kyrgyzstan did not cut too often, you need to adjust the axial clearance between the flywheel and the driver. Actually, between the flywheel hub and the driver in the axial direction, a gap must be set with a value between 0.2 millimeters and 0.6 millimeters.
Check this distance at baler Kyrgyzstan required every 60 hours of unit operation. Failure to check will result in an increase in clearance, which will affect the cutting frequency of the stud under heavy loads. However, it is important to adjust not only the axial clearance and fuse, but also the rest of the units.
Since the first and main reason why baler Kyrgyzstan bends needles is wrong adjusting the needle guard, then first you should make the correct adjustment of this particular device. In this case, the entire process must be performed strictly in accordance with the instructions that are in the operating manual of the unit.
Adjusting the baler needle guard Kyrgyzstan
According to the instructions, stop 3 (Fig. 21) must be squeezed out by the pipe of needles 10 without jamming and lowered back under the influence of spring 4 immediately after the pipe 10 leaves the bracket roller 12. When the state is off, the lower edge of the stop of the knitting machine of the Kyrgyzstan baler should be higher the supporting surface of the staple 2 by 0-2 mm.
The very process of adjusting the safety device for the needles of the Kyrgyzstan baler is performed using a rod 6 and a fork 8. In the case of using the unit not with a wire, but with a twine tying, a smaller spring 4 is placed on the seat of the spring 5, after which the adjustment procedure is performed again, taking into account all the same values and parameters.
Baler twine brake adjustment Kyrgyzstan
There is another reason why baler Kyrgyzstan bends needles... This is due to the twine brake. This device is designed to hold the needle in a neutral position. However, if the brake wears off under the influence of loads or drops, then during the shaking of the unit, the needles can fall into the bale chamber.
Naturally, this cannot be allowed. Therefore, the twine brake of the Kyrgyzstan baler is adjusted. To do this, the twine tucked between the brake plates is pulled under the influence of a force in the range from 0.5 to 1 kilogram-force. The adjustment process itself is carried out by preloading or by weakening the brake spring.
