    A reversing and adjustment mechanism, especially for a reversible plough adapted for hydraulically adjustable furrow width and hydraulic reversing of the plough, wherein the reversing and adjustment mechanism comprises a hydraulic cylinder (8) with a "hydraulic memory" for adjustment of the furrow width. The oil chambers on both sides of the ordinary piston (15) in the adjustment cylinder (8) communicate with a reservoir (24) via two pilot-controlled check valves (26, 25) with open passage toward the adjustment cylinder (8) and a second direction-control valve (10). The chamber (31) in the adjustment cylinder (8) between the rear head and a freely movable piston (17) communicates on the one hand with a hydraulic cylinder (7) for reversing the plough, preferably with the rod end thereof, via a first check valve (14) with open passage toward the reversing cylinder (7), and on the other hand communicates with the reservoir (24) via a flow-control valve (28) and a first direction-control valve (9). The reversing cylinder (7), on the end opposite its rod; i.e., preferably on the piston end, communicates on the one hand with the rod end of the adjustment cylinder (8) via a pilot-controlled check valve (36) with open passage toward the reversing cylinder (7) and a pilot-controlled check valve (32) with open passage toward the adjustment cylinder (8), and on other hand communicates with the reservoir (24) via a pilot-controlled check valve (36), the reversible flow-control valve (28) and a first direction-control valve (9).

    the low of the reversal using manual manipulation includes the first regulating direction K 19. The following operations are automatically carried out: first, the plow is rotated from the position of the set gripper to the minimum width of the gripper; then the reversing plow. The invention relates to agriculture, in particular to reversing mechanisms, and can be used on hydraulically controlled revolving plows, which do not need to adjust the furrow width and reversal of the plow.
    The purpose of the invention is to increase the reliability of work when reversing due to the possibility of transferring the plow to the position of minimum width and further returning it to its original position.
    Figure 1 shows a reversible plow with reversing and regulating mechanisms, mounted on the maximum working width, top view; Figure 2 is a diagram of a hydraulic system for a reversing and regulating mechanism;
    The reversing mechanism for reversible plows includes pairs of right- and left-side plow housings 3 fixed in frame 1 and parallel beam 2 on the front of it. the tractor in such a way that the shaft 4 is aligned with the center line of the tractor. At the rear end of the frame 1 there is a wheel 6 for adjusting the depth.
    A reversing hydraulic cylinder 7 serves to turn the plow around the shaft 4. A regulating hydraulic cylinder 8 serves to change the grip width of the plow.

    Dineney respectively to the pipeline 9 and 10. In the pipeline 9 is built in the shut-off valve 11, which opens in the direction of the hydraulic cylinder 7, and in the pipeline IO there is a built-in shut-off valve 2 and the shut-off valve 13 connected in parallel with the shut-off valve 12 and
    opening in the direction of the hydraulic cylinder 7 "
    The regulating hydraulic cylinder 8 has a free-moving piston 15 which is complementary to the conventional piston 14. The pistons 14 and 15 form a chamber 16 of variable volume.
    The cavity 17 between the rear head of the regulating hydraulic cylinder 8 and the additional piston 15 of the pipeline, 18, is connected to the pipeline 10, which through the first directional control valve I9 is manually operated and the flow-reversing valve 20 communicates with the tank for oil 21 of the tractor.
    The chamber 16 is connected to an oil tank 21 by an axial bore 22 formed in the stem 23 of the regulating hydraulic cylinder 8 and the pipeline 24.
    A second direction control valve 25 is installed on line 24 with manual control and a control shut-off valve 26 opening towards the control cylinder 8.
    The rod cavity 27 of the regulating hydraulic cylinder 8 is communicated through a pipeline 28 and a regulating check valve 29, opening into the second cylinder of the hydraulic cylinder 8, through a second directional control valve -25 with an oil container 21 and through a regulating check valve 30 connected in parallel to the valve 29, and pipeline 31, 32, through the flow reversing valve 20 and the first direction control valve 19, is also in communication with the tank 3 for oil 21.
    The device works as follows.
    In the case when the plow must be set to a greater width 0 of the grab, the oil from the tank 21 flows through the second direction-regulating valve 25, which controls the locking. Ny valve 29 and pipeline 28, in
    de 18), the pipelines 31, 32, the flow reversing valve 20, the pipeline 34 and the first directional control valve 19 will return to the tank 21.
    As the oil continues to flow into the cavity 7 and the pressure in it and in the chamber 16 will increase, the oil pressure in the pipeline 24 and the shut-off valve 26 will also increase.
    But since this shut-off valve is closed (since the second valve 25 is in the closed state and the control valve 26 does not flow
    noHoctb 27 hydraulic cylinders 8. At over-5 pressure to open), oil volume
    The piston 14 will squeeze oil out of the chamber 16, which through the axial channel 22, the pipe 24, the shut-off valve 26 and the second direction-regulating valve 25 will return to the capacity 21.
    In the case when the plow should be set to a smaller width, the oil from the tank 21 flows through
    in chamber 16 remains constant. However, the oil pressure from the first valve to 19 still acts on the piston of the reversing cylinder 7, which, moving, pulls in the rod. At the same time, the oil displaced from the oil cavity through the pipeline 9, the shut-off valve 11, which will be opened due to the presence of pressure in the pipeline
    the second valve 25, the shut-off valve 26, 10, through the pipeline 32, the reversing pipeline 24 and the axial channel 22 into the rudder flow valve 20, the pipeline chamber 16 regulating the hydraulic cylinder 34 and the first valve 19 will drain the oil 8. Extruded from the cavity 27 through pipe 28, shut-off valve 29 and second valve 25 is returned to tank 21.
    At. reversing the plow The first direction-regulating valve 19 is applied. This causes the oil from the tank 21 to flow through the conduit 35, wire 33, flow-reversing valve 20, pipeline 10 and shut-off valve 13 to the rod cavity of the reversing hydraulic cylinder 7, as well as through pipeline 18 in cavity 17.
    Since the regulating cylinder 8 has a smaller mass that can move than the reversing cylinder 7, the hydraulic cylinder 8 will first operate, namely the oil flow in the cavity 17 will press on the piston 15 and the oil on the plug in chamber 16 and the piston 14 will start to move , pushing the rod 23. Extruded 50 20 and further along the pipeline 34 while the oil from the cavity 27 will return through the first valve 19
    with in capacity 21.
    During the full stroke of the hydraulic cylinder piston 7, the plow will rotate 90 °.
    The oil pressure in the pipeline 10 and in the pipeline 33 continues to grow and this pressure acts on the piston 36 preloaded by the spring 35 in the flow-reversing valve 20. When C 1 acting on the piston 36 exceeds the force of the spring 35, the valve 20 will change the connection of the pipelines so that pipeline 32 will communicate with
    40 by pipeline 33, which is under pressure, and pipeline 10 will communicate with pipeline 34, and pressure will be applied to the piston cylinder 7 on the reversing cylinder 7 through pipe 9. Pressure will move the piston, pushing the rod.
    Extruded from the stock cavity of the oil through the pipeline 10 through the valve to reach through the pipe 28 to the shut-off valve 30 and the shut-off valve 29.
    Since the stop valve 29 will be closed at this time, the oil through the stop valve 30 (which opens under the action of pressure in the pipeline).
    into the container 21.
    The oil pressure in the pipeline 32 55 also acts on the pipe 31, and the oil through the shut-off valve 30 and the pipe 28 enters the cavity 27, moving the piston 14 and retraction of the rod 23 of the hydraulic cylinder 8. Oil in the chamber
    de 18), the conduits 31, 32, the flow-reversing valve 20, the conduit 34 and the first direction regulating valve 19 will return to the tank 21.
    As the oil continues to flow into the cavity 7 and the pressure in it and in the chamber 16 will increase, the oil pressure in the pipeline 24 and the shut-off valve 26 will also increase.
    But since this shut-off valve is closed (since the second valve 25 is in the closed state and the control valve 26 does not flow
    pressure to open) oil volume
    in chamber 16 remains constant. However, the oil pressure from the first valve 19 still acts on the piston of the reversing cylinder 7, which, moving, pulls in the rod. At the same time, the oil displaced from the cavity through the pipeline 9, the shut-off valve 11, which will be opened due to the presence of pressure in the pipeline
    10, through conduit 32, the flow valve 20 reversing flow, conduit 34 and the first valve 19 will drain
     20 and further on the pipeline 34 through the first valve 19 will return
    with in capacity 21.
    During the full stroke of the hydraulic cylinder piston 7, the plow will rotate 90 °.
    The oil pressure in the pipeline 10 and in the pipeline 33 continues to grow, and this pressure acts on the piston 36 preloaded by the spring 35 in the flow reversing valve 20. When С1ш acting on the piston 36 exceeds the force of the spring 35, the valve 20 will change the connection of the pipelines so that the pipeline 32 will communicate with
    pipeline 33, which is under pressure, and pipeline 10 will communicate with pipeline 34, and pressure will be applied to the piston through reversing cylinder 7 through pipe 9. Pressure will move the piston, pushing the rod.
    Extruded from the stock cavity of the oil through the pipeline 10 through the clave capacity 21.
    The oil pressure in the pipe 32 also acts on the pipe 31, and the oil enters the cavity 27 through the shut-off valve 30 and pipe 28, moving the piston 14 and retraction rod 23 of the hydraulic cylinder 8. Oil in the chamber

    16 through the axial passage 22 and the conduit 24 will apply pressure to the shut-off valve 26, which remains closed, as the second valve 25 closes, and as a result, the volume of oil in the chamber 16 will remain constant.
    However, the oil from cavity 17 will
    The piston and rod cavities of which are connected to separate pipelines with shut-off valves embedded in them, opening towards the reversing hydraulic cylinder, characterized in that, in order to increase the reliability of operation during reversal, to allow the plow to be displaced and pushed through the pipe 18 and 10, valve 20, pipeline 0. the minimum width of the grip from the water 34 and the first valve 19 to the container by further returning it to the first 21 until the piston 15 is not the initial position, it provides The regulator will go all the way to the end by a regulating hydraulic cylinder of a piston hydraulic cylinder 8. This position of the cavity of which is equipped with an additional piston 15 will correspond to a final piston with the formation of a reversing process. The reversing cylinder 7 and the regulating cylinder 8 will be in the position that was before the reversing process.
    A change in the transverse forces on the plow will result in a change in pressure in the lines 24 and 28 of the control cylinder 8, but until the first and second valves 19 and 25 are controlled, the pressure will stop at the shut-off valves 26 or 29 and 30.
