Description

The invention relates to transport, and in particular to vehicles equipped with a mechanism for replacing hook-type swap bodies adapted for the transport of lightweight agricultural goods (hay, straw, flooring, green grass mass, etc.), with a device for densifying the plant mass during loading .

A vehicle with a replaceable body is known for transporting agricultural goods, including lightweight (Fliegl company prospectus - a vehicle with a pushing wall), comprising a chassis, a replaceable body having a pushing wall with a hydraulic drive for unloading the loaded mass and compaction of loose low-density cargo. Unloading occurs under the influence of the pushing wall in the horizontal position of the body.

A disadvantage of the known vehicle is that the power drive of the pushing wall is an integral part of the interchangeable body and leads to an increase in its curb weight and, accordingly, cost.

The closest in technical essence to the claimed device is a prototype vehicle with an increased swap body for transportation of lightweight cargo (prospectuses of the All-Russian Institute of Agricultural Mechanization VIM and Moscow Plant of Experimental Designs MZOK - vehicles for working with swap bodies), including a chassis equipped with a mechanism with a hook frame for replacing swap bodies, having a lock for attaching the spars of swap bodies to the frame of the mechanism, and a replaceable body with a tow bar fixed to the front side of the body for connection to the hook frame.

The swap body is pulled from the ground onto the chassis and pushed to the ground by a hook-type body replacement mechanism by grabbing the hook of the coupling bracket fixed to the front side of the swap body. Unloading of goods occurs in a tipper manner with the rear tailgate open.

The disadvantage of a vehicle with such a swap body when working with lightweight cargoes is more than 40 percent underloading of the chassis and, consequently, a loss of performance.

The objective of the invention is to increase the productivity of vehicles equipped with mechanisms for replacing hook-type bodies, increasing the mass of the lightweight cargo carried by compaction.

The technical problem is achieved by the fact that in a vehicle with a removable body for transportation of light agricultural cargo, including a chassis equipped with a mechanism with a hook frame for replacing replaceable bodies, having a lock for attaching the side members of the replaceable bodies to the frame of the mechanism, and a replaceable body with a coupling bracket fixed on the front side of the body for connecting to the hook frame, according to the invention, the interchangeable body is equipped with a load sealing device driven by a hook frame.

In addition, the cargo sealing device is made in the form of front and rear sections telescopically connected to each other with the possibility of reciprocating movement of the front section, while the rear section is equipped with an automatic latch for fixing the mutual movement of the sections with the drive opening it from the lock; the latch is installed on the front of the spar of the rear section of the body and is made in the form of a guide cylinder with a spring-loaded slider, and the drive for opening it is made in the form of a two-shouldered lever with shoulders located at the ends of the shaft located along the body spar, while the front lever arm is connected to the slider, being under the action of the return spring in the extreme position in engagement with the front section, and the rear shoulder is located at the place of inclusion of the lock; the return spring is made in the form of a torsion bar, rigidly connected at one end coaxially with the shaft, and the other with the body spar.

The invention is illustrated by drawings.

Figure 1 presents a General view of the vehicle in the form of a tractor semi-trailer, equipped with a mechanism for replacing bodies in the unit, with a replaceable body equipped with a device for sealing lightweight cargo in the extended (a) position and retracted (b) position; figure 2 schematically shows the work of the same vehicle to install a removable body with a device for sealing cargo on the chassis before serving under loading lightweight cargo; figure 3 schematically shows a vehicle with a removable body for transportation of lightweight cargo in the process of filling the body with lightweight cargo at the time of commencement of compaction; figure 4 is the same at the time of completion of the seal; figure 5 is the same in the continuation of loading into an empty place in the body, formed after the first seal and the subsequent extension of the front section from the back for the next portion of the load; figure 6 is the same at the time of transfer of the body from the loading position to the transport position; figure 7 is the same at the time of dumping; on Fig - an example of the automatic latch for fixing the mutual movement of the front and rear sections of the body controlled by the lock attaching the spar of the removable body to the frame of the mechanism for changing bodies.

A vehicle with a swap body for transportation of light agricultural cargo includes a chassis 1 equipped with a mechanism 2 with a hook frame 3 for replacing swap bodies, with a lock 4 for attaching the side members 5 of the swap bodies to the frame of the mechanism 2, and a swap body 6 with a coupling bracket 7 fixed On the front side 8 body 6.

The replaceable body 6 is made in the form of the front 9 and rear 10 sections telescopically connected to each other with the possibility of reciprocating movement of the front section relative to the rear and driving it from the hook frame 3 connected to the coupling bracket 7, mounted on the front side 8 the front section 9, while the rear section 10 is provided with an automatic latch 11 mounted on the front of the spar 5 of the rear section 10.

The automatic latch 11 for fixing sections of the body between each other contains a guide cylinder 12 and a spring-loaded slider 13 moving along it.

The drive for opening the latch 11 is made in the form of a two-shouldered lever with shoulders located at the ends of a long shaft 14 located along the side member 5 of the body, while the front shoulder 15 of the lever is connected to the slider 13, which is under the action of the return spring 16 in engagement with section 9 , and the rear shoulder 17 of the lever is located at the inclusion of the lock 4.

The return spring 16 is made in the form of a torsion bar 18, rigidly connected at one end coaxially with the shaft 14 in a place located behind the rear arm 17 of the lever, and the other 19 with the body spar 5 from rotation around the longitudinal axis of the shaft 14.

The device operates as follows.

The replaceable body 6 is on the ground, and the front section 9 is pushed into the rear section 10 and secured with it from mutual movement by the latch 11. The chassis 1, equipped with a mechanism 2 for replacing bodies, drives up to the body and hook frame 3 hooks the body onto the bracket 7, lifts it the front part and pulls it onto the chassis frame 1. After installing the body in a horizontal position, turn on the lock 4, which connects the rear section 10 of the body with the frame of the mechanism 2 and opens the latch 11. The front section 9 is pulled out of the rear section 10 using the hook frame 3 to max battening the stroke its cylinder. In this position, the vehicle pulls under load with a light weight.

Sealing is achieved by the reciprocating movement of section 9 with respect to section 10, which is fixedly mounted by lock 4 on the frame of mechanism 2. After the first seal, section 9 extends and takes its initial position, while a void forms in the body to fill the next portion of the load.

When the load reaches the required density, turn off the lock 4, which opens the latch 11, which automatically locks the sections 9 and 10 of the body 6. The body 6 is then transferred to the transport position shown in Fig. 6, and the locks 4 are used to secure the body during movement. The duty cycle ends with the removal of the laden body from the chassis of the vehicle.

The slider 13 is under constant direct influence of the return spring 16 or torsion bar 18 through the shaft 14 and the lever arm 15. The latch is turned off by turning on the lock 4, which presses on the rear arm 17 of the lever and, overcoming the resistance of the spring 16 or torsion bar 18, turns the front arm 15 of the lever, which moves the slider 13 out of engagement with section 9.

The use of this vehicle will increase the density of the transported cargo, which will give a corresponding increase in productivity in the transportation of light cargo.
