Description

The invention relates to technological units, mainly for agricultural purposes, and can be used to drive front-and rear-mounted implements and machines, as well as for loading and transporting piece and packaged goods.

Known technological unit, adopted for the analogue, containing a self-propelled chassis with a cab and a frame, a rear linkage for aggregation with an agricultural implement and a removable farm for aggregation with a loader, pivotally mounted on the chassis frame in its middle part [1].

A disadvantage of the known technological unit is the inability to drive front-mounted agricultural implements and machines and to transport piece and packaged goods over long distances.

The known technological unit adopted for the prototype, containing a self-propelled chassis with a cabin and a frame, a winch with a rope, a loading platform, a portal boom with vertical U-shaped racks pivotally mounted on the chassis frame in its middle part, rotary hydraulic drive in a longitudinal vertical plane and equipped connecting the ends of the uprights with an end cross member on which the block [2] is fixed.

A disadvantage of the known technological unit is the inability to drive front-and rear-mounted implements and agricultural machinery.

An object of the invention is to expand the functionality of the technological unit.

The specified technical problem is solved by the fact that the cargo platform is made in the form of a body with a bottom, front and side walls installed in the rear of the chassis frame and equipped with a unit mounted on the front wall, the portal boom is equipped in its middle part with an additional cross member equipped with a block, and it can be installed in the front pushing, transport, rear loading and unloading and rear traction positions, and the end cross-beam of the boom is equipped with yoke brackets placed on either side of the block.

The invention is illustrated by drawings, where in Fig.1 shows a side view of a process unit in the front pushing position; figure 2 is a side view of the technological unit in the rear traction position; figure 3 is a side view of the technological unit in the transport (main lines) and rear loading and unloading (dash-dotted lines) positions; figure 4 is a view of figure 3.

The technological unit contains a self-propelled chassis 1 with a cab and a frame, a winch 2 with a rope 3, a loading platform 4, a portal boom 5 with vertical U-shaped struts 6, pivotally mounted on the chassis frame 1 in its middle part, a rotary hydraulic actuator 7 in a longitudinal vertical plane and provided with an end cross member 8 connecting the ends of the struts, on which the block 9 is fixed.

The cargo platform 4 is made in the form of a body with a bottom, front and side walls installed in the rear of the chassis frame 1 and equipped with a block 10 mounted on the front wall.

The portal boom 5 is equipped in its middle part with an additional cross member 11 provided with a block 12, and the end cross member 8 of the boom 5 is equipped with brackets 13 mounted on both sides of the block 9.

Symbols in the figures show: GR - cargo, CXM - agricultural machine (implement).

The portal boom 5 is configured to be reset from the front pushing to the transport, rear loading and unloading and rear traction position, which is achieved by turning it about a vertical axis lying in a vertical plane passing through the axis of longitudinal symmetry of the self-propelled chassis 1.

The technological unit operates as follows.

In the front pushing position of the boom 5, its end cross member 8 is located below the level of the underbody beyond the dimensions of the chassis 1, and the vertical U-shaped struts 6 cover the chassis of the chassis 1 from above. The brackets 13 are attached to the frame of the front-mounted SCM. When the technological unit moves in front, a predetermined agricultural work operation is performed, for example, cultivation.

In the rear traction position of the boom 5, its end cross member 8 is located below the level of the underbody beyond the size of the chassis 1, and the vertical U-shaped struts 6 cover the body outside its side walls. The brackets 13 are attached to the rear-mounted CXM frame. When the technological unit is moving forward, a predetermined agricultural work operation is performed, for example, plowing, cultivation, etc.

In the transport position of the boom 5, its end cross member 8 with block 9 is located above the bottom of the body, and the rope 3 of the winch 2 is sequentially stored in blocks 12 and 9 of the additional and end cross members and keeps the piece or packaged load of GR from longitudinal displacements along the bottom of the body when the technological unit moves .

In the rear loading and unloading position of the boom 5, its end cross member 8 is located above the level of the underbody beyond the size of the chassis 1, vertical U-shaped posts 6 cover the body outside its side walls, and the rope 3 of the winch 2 is stocked sequentially in blocks 10, 12 and 9 and provides lifting (lowering) of piece or packaged cargo of GR relative to the supporting surface of the technological unit for the purpose of self-loading (self-unloading) of the technological unit.

The economic effect is achieved due to the adaptability to the drive of the front- and rear-mounted implements and machines, as well as to the loading and transportation of piece and packaged goods.

Thanks to the implementation of the portal boom with the possibility of re-installation from the front pushing into the transport, rear loading and unloading and rear traction position, the total weight of the attachments necessary for aggregating the self-propelled chassis with agricultural implements and machines is reduced, and the presence of a body with front and side walls ensures reliable cargo retention on the platform during the loading of the technological unit. Grasping the cab of the chassis from above with vertical U-shaped racks in the front pushing position of the boom allows the operator to freely exit the cab, which increases safety.
