Abstract

The invention relates to agricultural machinery and can be used in reaping and forage harvesting machines. The purpose of the invention is to increase the reliability of the process by improving the copying of the relief of the floor. The attachment of the reaping machine (LM) consists of a lifting frame 1 and a balancing mechanism, including two-arm levers 2, which are mounted with the possibility of swinging in a horizontal plane, and a block of tension springs 3, with

connecting the ends of levers 2 directly to each other. The second ends of the levers 2 are connected via a link 4 to the LM platform, which is also pivotally connected to the frame 1. The ends of the spring block 3 are supported by slideways 13c that are rigidly fixed to the frame 1. When hitting a roughness of the floor with one side of the LM, the lever of the same name 2 is able to rotate in the swing plane, loosening the tension of the spring block 3,

which causes the rotation of the opposite lever 2 under the action of the rod 4, perceiving a part of the weight of the platform LM. The spring block 3 slides along the surface of the guides 13. By ordering its position during the operation of the device, as a result of the balancing mechanism, the load is balanced along the edges of the LM, which improves the transverse copying of the relief of the floor and increases the reliability of the process. 1 C.p. f-ls, 3 ill.

The invention relates to agricultural machinery, mainly to reaping machines.

Closest to the technical nature of the proposed device is a hinged header device, including a lifting frame, on which two-arm levers are mounted with the ability to swing the water plane, and tensile spring blocks located horizontally and perpendicular to the longitudinal axis of the header. Each of the spring blocks is connected by a bracket and a tension bolt to the nearest two-arm lever with one end and attached to the intermediate bracket of the lifting frame with the other. When hitting a roughness of the soil with the right or left side of the header, the spring block of the same name weakens the tension and does not absorb its part of the weight of the header, while only the opposite spring block works.

The disadvantage is that each of the spring blocks acts on only one side of the header, i.e. uneven weighting of the header occurs during transverse copying, which reduces the reliability of the process.

The aim of the invention is to increase the reliability of the process by improving the copying of the relief of the floor.

This goal is achieved in that the ends of the spring blocks are interconnected.

In addition, each end of the spring block of the two-arm levers is provided with guides rigidly mounted on the frame.

In FIG. 1 shows a General view of the reaper with the proposed attachment, right view; in FIG. 2 - view A

in FIG. 1; in FIG. 3 - node I in FIG. 1 (increased).

The attachment of the reaping machine consists of a lifting frame 1 and a mechanism

balancing, including two-arm levers 2, mounted symmetrically on the supporting beam of the lifting frame 1 with the possibility of swinging relative to points Oi and 02. and a block of tension springs 3, which connects the ends of the two-arm levers 2 directly to each other. The second ends of the two-arm levers 2 are connected via a link 4 to the platform 5 of the reaper. The lifting frame is a spatial structure in the form of sidewalls rigidly interconnected by a supporting beam, which are pivotally attached to the skeleton of an energy tool 6, for example, a reversible tractor. 5 Harvesting Platform

the machines are pivotally connected to the front ends of the hoist frame. The latter is pivotally connected to the lower links of the hinge plate 7 of the power unit 6. The block of tension springs 3 can be structurally made according to

the length of two parts, each of which, to increase rigidity and prevent resonance during operation, consists of a large 8 and a small 9 tensile springs arranged coaxially. Both parts

interconnected by means of plugs 10 and studs 11. To ensure an orderly arrangement of the springs in the block, a separation plate 12 is used. The ends of the spring block 3 are supported by guides 13 fixed to the lifting frame.

The device operates as follows.

When hitting an uneven floor with one side of the reaping machine, let's say

right support shoe of the same name

two-arm lever 2 tends to turn

clockwise around race 02, loosens the tension of the spring block 3. At the same time, the left two-arm lever 2 is able to rotate a certain angle also clockwise around point 01 by the left link 4, which receives part of the weight of the platform 5 of the reaper, which means load balancing on the left and right sides of the reaping machine when transversely copying the relief of the floor. The springs 8 included in the spring block 3, in the process of copying the relief, slide over the surface of the guides 13, ordering their position during operation of the device.

Due to the fact that the ends of the spring blocks are interconnected, an increase in the shift productivity of the reaping machine is achieved by 2., A% by increasing the reliability of the process

process by improving the copying of the floor.
