The wall 10 is suspended from the front ends of the carriage 15 by hinges 30 on the longitudinal arm 13 and the hydraulic cylinders 27 which are connected with levers jointed stems and hulls on swinging supports 28 with the rear ends of the carriage 15 so that the swinging support 28 in the front end position is rigidly fixed in the carriage 15 with exposed back trailing arm 13, and the rear its terminals 29 is fixed to the carriage 15 with the guides 16.

The hydraulic trailer hitch 3 handling mechanism 2 is configured to automatically reverse the movement of the traction hydraulic machines 5 and regulation of its power of influence depending on the degree of compaction. It is equipped with two pressure sensors 31 installed at the outlet of the electromagnetic valve 4, and the control unit 6 is equipped with a block 32 automatic switching of the electromagnetic valve 4 from the signals of the pressure sensors 31. The communication control unit 6 with an electromagnetic valve may be remotely or flexible cable or a radio signal.

The pressure sensors are made in the form of adjustable rela the pressure 33 and 34, installed at the outlet of the electromagnetic valve 4, with the block 32 auto switch with an electromagnetic on-off switch 35, relay block 36 and the three-position manual switch 37 of the power supply from the neutral position to the position for automatic and position for push button control operation the traction hydraulic machines 5, with automatic reversal traction hydraulic machines 5 made from signals of adjustable pressure switch 33, governors, together with the relay block 36, the power of the electromagnetic on-off switch 35 and configured on a pressure corresponding to the force to the trailer hitch 3 handling mechanism 2 removable body 8 that creates the necessary degree of compaction cargo in the back.

The device operates as follows.

Chassis 1 gears swap body trailer hitch 3 handling mechanism 2, raises its front part and approaching him until it touches the middle of the side members 9 of the support rollers 7 handling mechanism 2 and pulls up on his frame handling mechanism, when the body 8 is in an inclined condition, the wall 10, is suspended from the carriage 15 in the upper rails 16 and recorded with them swinging supports Hydra the cylinder, under its own weight engages the rear end stop 22, resting in him slide 17. Such position of the wall 10 relative to the body 8 corresponds to simultaneous coincidence of the traction links 11 with grippers 18 of the front of the lock 24 and the rear lock 25 two-way stop 23, which allows the mechanism 26 to enable the front 24 and rear 25 locks. Vehicle with a mechanism for sealing lightweight cargo ready for loading.

As the wall 10 is fixed concerning axis of the rear support rollers 7 chassis 1 by means of the slide 17, the two castles 24, 25 and two-way stop 23, when exposed to the body 8 of the trailer hitch 3 is moving the body relative to the chassis 1 and respectively, relative to the wall 10, which divides the space of the body into two parts, changing in the process of moving their volumes, alternately forming a sliding and sliding parts of the body. The loading is carried out as follows.

1 - first, the body 8 is filled to the same height on both sides of the wall 10;

2 - then turn on automatic hydraulic reciprocating drawbar device 3 when filling in the body, ensuring that the flow of cargo that fills the body, was in its sliding part.

If the direction of the seal of the chassis 1 moves against the sustained fashion combine in an amount visually necessary for the direction of the flow of cargo in the sliding part of the body 8, respectively, for the wall, if the body relative to the chassis moves back or in front of it when moving the body forward. In the process of sealing a gradual shortening of moves (Zā†’0) of the reciprocating movement of the body 8 relative to the chassis 1, and accordingly the wall 10, so at some point there comes a stop because of bridging of the contacts of the pressure switches 33 and 34, which corresponds to the maximum degree of compaction for a given setting of the pressure switch.

The switch 37 is moved to the neutral position. Loaded body 8 may be relative to the chassis in a position not corresponding to the transport, so off mechanism 26 locks 24 and 25, the body is set in the transport position and the vehicle is put under tipper unloading. When unloading open the tailgate and tilt the body, and the wall 10, which is not connected with the slide 17 can move in the upper rails 16 under the action of its own weight and the weight of the cargo, and also to rotate the cylinders 27 around the hinges 30 after swinging the supports 28 unlocks the carriage arms 13 of the wall 10 and lock the clamp 29 table 15 relative to the guide 16. Balanced body 8 is lowered with simultaneous surge is receiving the rear side and the wall 10.

Automatic switching of the electromagnetic valve 4 is as follows. Include the switch 37, closing the contacts ab. Power is being supplied to the relay 33, normally-open contacts speakers and through the normally-closed contacts dd switch 35 and a cd and a push button switch 40 of the remote control 6 to the contact A2 of the electromagnetic valve 4, which includes hydraulic machines 5 and accordingly sealing mechanism of the cargo. The hydraulic machines 5 may be either a hydraulic cylinder 38, resulting in the action of the drawbar link 3 handling mechanism 2, or hydromotors 39, torque winch traction chain.

In the compaction process is a continuous cyclical increase the density of the material and increase the working pressure in the hydraulic drive, so at the moment of attaining the values of the working pressure corresponding to the specified degree of compaction, actuates a pressure switch 33 and closes the contacts sa, feeding power to the electromagnetic switch 35, which opens the contacts dd off valve 4 and the stopping of hydraulic machines 5 and includes contacts dc powered relay block 36 and through the normally-closed contacts ab push-button switch 40 of the remote control 6 to the contact A1 of the valve, reversive the hydraulic machines. When reaching into the hydraulic system operating the first pressure, corresponding to the configuration of the relay 34, it opens normally-closed contacts of the AC supply relay block 36 and the switch 35. Is the switch 35, and again close the contacts dd. The cycle repeats. Since the density of the cargo increases, therefore, decreases the rise time of the operating pressure and reduced working stroke of the hydraulic machine to a complete stop. At the moment full stop or near the switch 37 is switched to the neutral position.

With the closure of the contacts of the AC switch 37 of the control valve 4 is carried by a push button switch 40 of the remote control 6.

The use of the vehicle will increase the performance when loading from harvesters loose cargo low density by combining the processes of loading with seal and improved ergonomics management of these processes.
