(54) VEHICLE FOR THE CARRIAGE OF LIGHTWEIGHT

1The invention relates to vehicles, mainly in autotractor trailers for the transport of lightweight goods (hay, straw, chaff, etc.) with a device for compacting the vegetable mass during loading.

A vehicle for transporting a lightweight cargo is known, comprising a telescopic body hinged with the rear part on the vehicle frame with the possibility of tilting by means of a lifting ram, while the front part of the body is placed on the frame with the possibility of longitudinal movement through an additional ram I.

This vehicle can also be used to compact loaded vegetable mass by periodically turning on the first hydraulic cylinder and moving the front body to the rear. However, the amount of movement of the front body is equal to the stroke of the cylinder bore, therefore the total length of the two bodies and their capacity are limited by the length of the hydraulic cylinder. In addition, in this design most difficult

an efficient method of compaction is in an inclined position / body, since the compaction process should not be controlled separately by two hydraulic cylinders.

In another variant of this vehicle, the front body of a greater length than the rear one is portion waged using a hydraulic cylinder with a ratchet. This system is complex and works only in the horizontal position of the body. It does not allow compaction when the body is raised, i.e. in the most efficient mode, since in this position the ratchet is disconnected from the body.

The purpose of the invention is to increase the performance of the vehicle by increasing the compaction efficiency of the transported cargo.

Claims (2)

The goal is achieved in that the vehicle 20 is provided with a lever pivotally attached to the vehicle frame, to which is pivotally attached a tractor connected with an additional power cylinder, and the lift cylinder is connected to the specified lever. In addition, rails can be attached to the bottom of the rear of the body to move along the end of the lever connected to the thrust. The drawing shows a vehicle, side view. The vehicle contains a telescopic body consisting of front 1 and rear 2 parts, a frame 3 with wheel moves, to which the rear part of the body is pivotally attached with the possibility of tilting backwards, a hydraulic cylinder 4 of lift, connected to the lever 5, and tu 6 with an additional hydraulic cylinder 7. The lever 5 is hinged at one end with the frame, and the other with thrust 6 and an additional hydraulic cylinder 7. At the same time, the end of the lever connected to the thrust can move in guides 8 fixed to the rear end of the body: extra kronschteynom hydraulic cylinder connected to the front end 9, which lies on the supports 10 of the frame. The vehicle works both on the move when loading it from fodder harvesters, and at the hospital when loading nozzle via cyclic action. As the body is filled, an additional hydraulic cylinder is put into operation, which, in a horizontal position, partially seals the mass, draws the front body into the rear body. From this position, with a reduced body length, the mass is further compacted by a hydraulic cylinder 4 lifts. When it is turned on, the lever 5 connected to fiHM begins to tilt the body, called the lid around the rear hinge, connecting the body to the center of the transport; 1. Odioimorem with ashm the end of the levers 5 is mixed in the guides 8 and carries away; After 6 is connected to the hydrocyliidrome 7. At the same time, the otapsa is finally pulled into the rear part of the body, and the mass consolidation cycle is completed. SiiTCMi when the body returns to its original position, the compacted mass remains in the rear part of the body, and the front is released under the load of the next portion, and so the cycles can be repeated until the maximum compaction of the mass in the rear part of the body. The compaction of the feed mass at the front of the body in a horizontal position is produced by an additional hydraulic cylinder. After filling the entire body volume, the mass is transported to harvesting centers or to places of consumption. When unloading, they first open the tailgate of the body, then turn on the additional hydraulic cylinder, which, reducing the total length of the body in a horizontal position, also produces its partial unloading. Full unloading occurs when the shortened body overturns by the lifting cylinder. The most effective mass consolidation occurs simultaneously with the rise of the body in which a component force on the weight of the mass appears, which coincides in direction with the action of the sealing force. Moreover, the same component force contributes to holding the mass when the body returns to its original position, as a result of which the front part is released to receive a new portion of cargo. Preliminary studies on the compaction of plant mass and calculations show that the use of the proposed vehicle allows an increase in productivity by 30-40% in the transportation of lightweight agricultural goods. Claim 1. A vehicle for transporting a lightweight cargo, comprising a telescopic body hinged with a rear part on the frame of the vehicle with the possibility of tilting by means of a lift ram, the front part of the body being placed on the frame with the possibility of longitudinal movement through an additional ram, characterized by that, in order to increase vehicle performance by increasing the compaction efficiency of the transported cargo, about provided pivotally fixed to the vehicle frame arm, which is hinged rod associated with the additional power cylinder, the power cylinder is attached to said lifting levers. 2. A vehicle according to claim 1, characterized in that rails are mounted on the bottom of the rear part of the body for moving the end of the lever connected to the thrust.
