Description

one

The invention relates to agricultural machinery, in particular to devices for cleaning rows of root crops and between the crops from crop residues used in machines for harvesting root crops and their tops.

A device is known for cleaning rows of root crops and aisles from plant residues, comprising a horizontally mounted shaft with cleaning elements made in the form of bunches of. elastic elastic pile. These elements in the known device are located in the aisles between, and over a row of root crops, elastic beels are installed, made for example of rubber. However, rubber billes do not provide the necessary quality of cleaning the heads of root crops from tops, wear out quickly and knock the roots out of the soil, damaging them.

The device closest to the proposed device for cleaning rows of root crops and between the fields from plant residues, contains a horizontally mounted shaft with cleaning elements in the form of bunches of elastic-elastic pile .2. In this device, tufts of piles are intended both for cleaning between the rows, and for cleaning the heads of root crops from tops.

However, this device does not provide high-quality cleaning of the heads of root crops without their damage, especially in the multi-performance of this device. In addition, this device is unsuitable when harvesting the tops of rosary sugar beets, as it damages the central apical part of the roots. The purpose of the invention is to improve the quality of cleaning of rows of root crops and inter-planting from plant residues.

This is achieved by the fact that the cleaning elements for cleaning between the rows have a greater stiffness compared to the hardiness of the elements for cleaning rows of root crops due to the greater number of tufts.

FIG. 1 shows a device for cleaning rows of root crops and between the crops from plant residues; in fig. 2 is a section A-A in FIG. one; in fig. 3 - section B - B in FIG. I.

The device is made in the form of a horizontally mounted shaft 1, on which

25 secured cleaning elements, made in the form of bundles 2 of schrugoelastichesky pile. At the same time, the beams 2 for cleaning the rows of coryeplods are fixed on the shaft 1 on one side with box-shaped

30 clips 3 and slat clamps 4,

while the beams 2 for cleaning between the rows are fixed on both sides of this shaft by box-shaped clips 3. Thus, the number of beams in the cleaning elements intended for cleaning the aisles is greater than the number of beams in the cleaning elements for cleaning rows of root crops, i.e. The first cleaning elements are more rigid than the second.

In operation, the device moves along rows of root crops with pre-cut tops. The cleaning elements made of bundles 2, rotating with the shaft 1, act on the heads of the root crops, clean them and sweep them into the aisle, from which the crop residues with bundles 2 are removed to the harvested field. Since the cleaning elements for cleaning the rows are made with a smaller number of tufts 2, the surface of the heads of the root crops to be treated is subjected to minimal impact loads, thus reducing the quality of the cleaning without damaging the central apical kidney of the root crop.
