Description

(S) PACKING DEVICE OF ROOT REMOVAL

I,; - ....

The invention relates to the field of agricultural machines, in particular, to the undermining devices of the machines for harvesting of tubers and vegetables.

A digging device of a root-and-field harvesting machine is known, including the installed one: 1a plowshare hangers with a grate area and hinged crankboard and a drive mechanism 1 j hinged on it.

The disadvantage of the device is the clogging and kneading of the grate with the soil due to the absence of mutual displacement of the grate, as a result of which its separation capacity is reduced.

The purpose of the invention is to eliminate clogging, grating and increase its separation capacity.

This is achieved by the fact that the cutter is made sectional by one hundred by alternating the grate bars of each section, which are equipped with limiting MACHINES

gels of their turn, placed on a share and a rod. In addition, the grate sections of the lattice having a rotation stop relative to the connecting rod, are made shorter than the grate section having a rotation stop relative to the plowshare.

The drawing schematically shows a podkatshapvgee device.

It consists of the established

to on emeha hangers 2, an articulated grate hinged to it, full of sections 3 and t, the grates alternate each other across the width of the plowshare 2, and the mechanism

15 of the drive, including crank 5 and connecting rod 6. Each of sections 3 and 4 has rotation stops, which are mounted respectively on the plowshare 2 and the connecting rod b. For section 3, osnat

26, the supporting element 7i, the rotation limiter is the rear surface of the plowshare 2, and for section 4, which has the supporting element B,

Lirueni stop 9i mounted on the connecting rod 6.

In order to avoid losses, the corneal club is not barren in the zone of their transfer from the grate to the separator (in the harvester scheme), the grate bars of the grate section 3, which has a rotation stop relative to the connecting rod, are shorter than the grates of section k, which have a rotation stop relative to the plowshare

The device works as follows. . .

The Z-cut cutter enters the Kopos + Mkovy lattice, where it is separated. In the process of oscillation of the plowshare 2, the grate sections of section 3 and k of the reel move along different trajectories of the movement, because under the action of the weight of the bed section 3 is integral with the share 2 and makes joint with it oscillations along the arc, while the section on the connecting rod b, it moves in a closed curve.

For the estimates of the alternate impact of the sections on the formation, its intensive crumbling and separation has been performed.

the mutual displacement of the grate of the grate makes it possible to clean it itself, which excludes its closure

and enhances the separation ability of the device.

Claims (2)

1. Podkapyvayuschaya device root-harvesting machine, including mounted on hangers share with articulated grate, and a crank drive, characterized in that, in order to avoid clogging of the racket and increase its separating ability, the grate is made sectional, with the alternating alternation of the grates of each section, which are provided with limits for their rotation, is positioned accordingly on the plowshare and connecting rod. 2. U.S.A. of claim 1, d and t that the grate the sections of the lattice, having a rotation stop relative to the connecting rod, are made shorter than the shaft sections of the section having a rotation stop relative to the plowshare.
