Description

(5) DEVICE FOR DESTRUCTION AND SEPARATION

one

The invention relates to agricultural machinery, in particular, to the working bodies of machines for harvesting plant roots.

,,

A device for destruction is known.

and separation of the soil layer, which includes a number of rotating drums mounted on the frame and made in the form of discs with jl rods fixed on their rim Q.

A disadvantage of the device is the low loosening ability of the bar drums when harvesting crops having woven rhizomes. J5

The purpose of the invention is to increase the separation capacity due to loosening of the formation.

This is achieved in that the device is provided with an a-linear guide mounted on ramekri-20 and placed on rod pins, with the rods being installed in the discs with possibility. axial displacements and have installed

rollers at their ends to interact with the guide.

FIG. 1 shows a device for the destruction and separation of a soil layer, side view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 shows an embodiment of the device. in fig. section bb in fig. 2

A device for the destruction and separation of a soil layer consists of several rod-shaped drums 1, mounted with bearings 2 on a common frame 3 and driven by sprockets k.

Each drum consists of a shaft 5 and disks 6 rigidly attached to it with holes made around the periphery, into which rods 7 are mounted with the possibility of axial movements. Each bar 7 is equipped with pins 8 and, on one side, an emphasis E and a roller 10. On the rods 7 between stops E and the outer surface of the discs 6 are fitted with springs 11. The device is equipped with a curved guide 12 fixed to the frame, with which the rollers 10 interact.

In the embodiment (Fig. 3), the curvilinear guide 12 is made two-sided, and the rods 7 are provided with pins 8 and a roller 10 located at one of the ends.

During the operation of the device, the undermined stratum, consisting of soil and rhizomes, is moved along the rotating drum 1. When the drum 1 rotates, the rods 7 with pins 8 are inserted into the formation and crush it. Simultaneously with the rotation of the drum in the longitudinal plane, the roller 10 interacts with the curved guide 12 and moves the spring-loaded rods 7 with the pins 8 in the transverse direction, and the surface of the guide 12 is chosen so that adjacent rods move towards each other and thereby intensively loosen the undermined layer The soil from the impact of rods and pins is destroyed, separated from the rhizomes and sieved through the gaps between the rods, and the rhizomes are transported to the next working body of the machine.

The invention makes it possible to increase the separation capacity of the device due to the presence of pins on the drum rods and the possibility of axial movements of the rods.
