During the forward movement of the working member, the disks 4, recessed at different depths, are located root up the roots and remove them from the soil. 3 il.

Description

FIG. one

The invention relates to the field of agricultural engineering, in particular to the working bodies of harvesting machines, for example, beet harvesters.

The purpose of the invention is to increase productivity and reduce losses and damage to root crops.

Figure 1 shows a diagram of the root-working device of the harvesting machine, side view; figure 2 - the same, zid top; on fig.Z - the same, front view.

The root-removing working body of the harvester includes a pair of symmetrical struts 1 attached to the frame 2 of the harvester. On racks 1 mounted on wasps x 3, at least two disks A. The disks 4, placed on different racks 1, are mounted relative to each other at an angle in the vertical and horizontal planes. The working edge of the trailing disk 4 is located below the previous edge of the front disk along the disk 4, i.e. depth of digging in each disk The rack 1 of each digging element, carrying two successively mounted disks 4, has an angular shape and is located on the side of the non-working surface of the latter.

The root-extracting working body of the harvesting machine works as follows.

In the process of moving the beet harvesting machine across the field, a layer of earth, captured by a solution of the front part of the device, is compressed in layers by each pair of disks placed opposite each other, and the roots have a conical shape,

squeezed out of the soil. The activation of the process of extracting root crops occurs due to the fact that the disks 4 are fixed loosely on the axles 3 racks 1, therefore, rolling in the soil, the disks 4 rotate in the direction of movement of the machine and the root vegetable clamped on all sides rises. The compressible layer is well crushed by the disks 4 rotating at different depths and the roots in it, falling into the solution between the last disks 4 in the course of movement, are actively extracted from the soil and fed to the receiving device. The downstream discs 4, when operating on heavily littered areas, are also weed separators from the captured mass, i.e. prevent the overhang of plant residues on the racks of the working body.
