FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in the design of a combine harvester.

The purpose of the invention is to preserve the form of the pile by increasing the uniformity of the layer-by-layer distribution and compaction of straw in the hopper.

Fig, I shows a diagram of a strawberry; Fig, 2 is a diagram of the supply bottom, top view; FIG. 3 is the same side view; 4 is a diagram of the distribution and sealing mechanism.

The ratchet device has latches 32 and cams 33. Rods 25 are provided with latches 34, and stops 35 are mounted around the leads 30.

The drive of the straw leveling and compaction mechanism includes a chain with sprockets. 36, a shaft 37 with supports 38, a crank 39, a connecting rod 40, supports 41, a chain 42 with a reverse box 43,

The box 43 consists of a pair of cylindrical gears 44, a pair of sprockets 45, a chain transmission 46 and a clutch with a lever switch 47, Vtulochno

th mechanism; Fig 6 is a diagram of a chain mechanism; Fig, 7 is a diagram of the mechanism of the carriage; on Fig diagram of the ratchet carriage device.

The straw straw bin consists of two sides 1., front wall 2, feed bottom 3, rear valve 4, block 5 hydraulic cylinders, crane 6 controls and working platform 7, Falling bottom 3 is made in the form of a U-shaped frame with thickened fingers welded to the front bar 8, and with the help of rollers 9 and hinges 10 movable pins 11 are attached, six rollers 12 are welded to the bottom 3 for the lower hydraulic cylinders 13 and suspensions, 14, with which it is attached to the sides 1, the back valve 4 is designed as lattice and attached to the supports 15,

Above the hopper there is a mechanism for leveling and compaction of straw mixed with flooring, which consists of channel guides 16 and two transverse beams 17 and 18. On the guides 16 there are carriages 19, inside which there are support rollers 20 with an outer rectangular groove, B The shaft 21 is installed at the end of the frame with leading sprockets 22, and tensioning sprockets 23 are placed at the opposite end. Inside Yush x 16, the sprockets 22 and support rollers 20 pass through the roller bush 24 and its ends are connected to the carriage 19.

In the carriage 19 there are vertical bars 25, in the lower part of which a pipe 26 with tines is fixed, and in the upper part limiters 27 are installed.

The rods 25 are mounted in the guide rollers 28 of the carriage 19 and are engaged with an asterisk 29 fitted with leads 30 and a spring 31.

Straw straw works as follows.

The process of forming a pile with the action of the pipe 26 begins after a straw of 60-80 cm in height forms on the bottom of the hopper 3. At the same time, the rods 25 are in the lower position and their stopper 27 rests on the surface of the carriage 19.

25 Being in rotation, shaft 37 with cranks 39 through rods 40 oscillates guide rails 16 with carriages 19 with barrels 25 and pipe 26 mounted on them. Simultaneously shaft 37 rotates shaft through circuit 42 and reversible box 43 21 with drive sprockets 22, which are in engagement: a research institute with a stub-roller chain 24, whose carriages 19 extend along oscillating guides 6, tube 26, being in complex motion and moving along the hoof from the rear valve 4 to the front wall 2, flattens and compacted straw. When approaching the front wall 2, the upper leads 30 on the carriages 19 meet with the upper stops, resulting in sprockets 29

D5 rotates and the rods 25 are raised together with the pipe 26 by a predetermined amount (about 80 mm. At the same time, the lower stop 48 of the chain 24, which is in the extreme position; acts on the lever of the switch 47 of the reversing box 43, moves the friction clutch to the right side and the drive shaft is connected to the star 45, connected to the chain 46 and the same asterisk on the driven shaft. After the reverse, the chain 24 begins to move in the opposite direction, moving the carriage 19 from the front wall --- ki 2 to the rear valve 4,

5 Being in rotation, the shaft 37 with the cranks 39 through the connecting rods 40 oscillates the guides 16 with the carriages 19 with the rods 25 and the tube 26 mounted on them. Simultaneously from the shaft 37 through the shaft 42 and the reversible box 43 the shaft is rotated 21 with drive sprockets 22, which are in engagement: a research institute with a stub-roller chain 24, whose carriages 19 extend along oscillating guides 6, tube 26, being in complex motion and moving along the hoof from the rear valve 4 to the front wall 2, leveling and compacting straw When approaching the front wall 2, the upper leads 30 on the carriages 19 meet with the upper stops, resulting in sprockets 29

and the drivers 30, moving away from the stops 48, are pulled away by the springs 31 to the initial position. When the carriage 19 approaches the rear valve 4, the lower drivers 30, connected through a ratchet device with sprockets 29, are in contact with the first bolt 48, turn them and they lift the rods 25. Movement to the rear valve 4 continues until the upper chain stop 48 approaches the switch lever 47, With the shift of the clutch to the left, the movement from the drive shaft is transmitted to the chain 24 by gears 44 in the opposite direction. After the reverse, the carriage 19 is returned in the opposite direction, and the pipe 26 is lifted to the new level and begins to process the next layer of straw fed to the stacker. Thus, the lifting of the pipe 26 is performed each time around the front wall 2 and the rear valve 4 of the hopper and closely coincides with the moment of reversal of the carriages 19,

In the straw-filled hopper, prior to unloading the formed hay, the pipe 26 is in the upper position under the carriages 19 and moves from the rear valve 4. At this time, the control valve turns to Open, under the action of the bottom 3 gravity force on the bottom hydraulic cylinder 13 and located On the stubs of straw, oil begins to exit through the open valve 6, then it is fed into the upper hydraulic cylinder. After that, the bottom 3, with a shock of straw weighing about 500 kg, is lowered onto the hinged suspension 14 and the rear flap 4 opens. At this point, the valve 6 is temporarily closed for a short period of unloading straw.

from the stopper. Simultaneously with the lift 45, the innovations on the rotary suspensions from the rear valve 4 of the liner 30 can be brought into contact with the stops 35 and spring-loaded when unloading the stack.

The second 32 snapshots interacting with the cams 33 are turned off. At the same time, the controlled electromagnetic lock 34, which holds the rods 25, is triggered. With the release of the sprockets 29 and the rods 25, the pipe 26 under its own weight is lowered into the original

position, until it stops limiters 27.

At the end of the unloading of the stacks, the valve 6 reopens under the action of force on the rods of the upper hydrocylinders 13, created by the head;

the rear valve 4, the oil is supplied to the lower hydraulic cylinder 13 and the bottom 3 is closed in advance, and the rear valve 4 is late. After that, the valve 6 is closed, and a new process is started for the formation of another mound.
