Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The aim of the invention is to increase the efficiency of soil crumbling and reduction of metal intensity. The device comprises a frame 1, on which, by means of racks 2, a looser disk 3 larger in diameter and an elastic transport disk 4 are fixed. The looser disk 5 smaller in diameter is connected to disk 4 by means of a bracket 6. Different diameters 3 and 5 are installed under different camber angles relative to the longitudinal plane of symmetry. The elastic disk 4 is inclined between the loose disks 3 and 5 and above the floor surface. The axis 8 of the disk 4 is shifted backward about the axis 7 of the larger diameter of the disk 3. The loose discs 3 and 5, rotated by adhesion to the ground, break its connection with the roots. The latter are removed by pinching between the large diameter disk 3 and the elastic disk 4 and are transferred by the beater to the separating organs. 4 hp f-ly, 2 ill. (L

The invention relates to agricultural machinery, in particular, machines for extracting root crops from the soil. The purpose of the invention is to increase the efficiency of soil crumbling and reduce metal consumption, as well as reduce the trauma of extracted roots and simplify the design,

FIG. 1 shows a device for extracting root crops from the soil, side view; in fig. 2 - the same, front view.

A device for extracting root fruits is fastened on frame 1 by means of racks 2, made in the form of frames 1 located on the frame 1 with independent movement and fixation, on which the loose disk 3 larger in diameter and elastic transporting disk 4 are fixed. The smaller loose diameter The disk 5 is connected to the elastic disk 4 by means of a bracket 6.

The larger diameter loose disk 3 and the elastic transporting disk 4 are mounted on axles 7 and 8 pillars 2, and the smaller diameter diameter loose disk 5 is mounted on axis 9 of bracket 6.

Differently sized loosening discs 3 and 5 are installed at different camber angles relative to the longitudinal plane of symmetry, and the elastic transporting disc 4 is inclined between the loosening discs and above the floor surface, with the axis 8 on which it is mounted shifted backward along the larger axis 7 diameter of loose disk 3.

The device works in the following way. I

The main loosening discs 3 and 5, which are rotated by adhesion to the soil, break its connection with the roots. Root crops, the connection of which with the soil is broken, are extracted by pinching between the large disc 3 with diameter 3 and the elastic transport disc 4, are lifted and transmitted, for example, by means of a beater not interrupted by the organs. The installation of loosely sized disks 3 and 5 with different camber angles relative to the longitudinal plane of symmetry leads to the appearance of various peripheral speeds

these and other disks, which contributes to the emergence of internal shearing, tangential stresses in the soil layer and, as a result, its effective crumbling. This leads to a better cleaning of root crops from sticking soil and a decrease in free soil in the pile, and the use of different-sized disks reduces the metal content of the structure.

The fastening of the discs by means of racks 2, made in the form of two mutually unrelated semi-aisles, allows the frontal zone of capture and cleaving of the roots to be varied depending on their yield by displacing the racks 2 along frame 1.

The installed elastic disc 4 provides a reduction in the injuries of large root crops by creating an elastic zone for their pinching and transportation, and also simplifies the design of the device.

Fasten smaller loose bottom-. By means of a bracket 6 mounted on an axis 8 of a rack 2, frame 3 to frame 1 reduces the metal consumption of the structure of the device for extracting root crops from the soil.
