Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to separation devices. The purpose of the invention is to intensify the process of destruction of soil lumps. The rotary separator consists of shafts 1 with a transporting set-w / parrying elements 2, combined in two sections. A separating drum 3 is mounted between the sections. On the shaft 4 of the separating drum there are mounted disks 5 with rods 6 on their peripheral part. Adjacent rods 6 are interconnected by rods 7 so that the net surface of drum 3 is formed. The shafts with conveying and separating elements 2 and separating drum 3 are provided with an actuator 8 for their rotation. The drive 8 provides an increase in speed in each section in the direction of the feed of the separated pile, and on the separation drums - a decrease in speed compared to the speed of the last shaft of the previous section. 1 z.p, f-ly, 2 ill.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to separation devices.

The purpose of the invention is to improve the quality of separation by intensifying the process of destruction of soil lumps.

1 shows a rotary separator, side view; figure 2 is the same, the view in the plan.

The rotary separator consists of shafts 1 with transporting and separating elements 2, combined into two sections. A separating drum 3 is mounted between the sections. On the shaft 4 of the separating drum there are mounted disks 5 with rods on their peripheral part. The rods 6 are interconnected with the rods 7 and form the mesh surface of the drum 3. The shafts 1 with the transporting and separating elements 2 and the separating drum 3 are equipped with an actuator 8 for their rotation. and on the separating drum - a reduction in speed compared with the speed of the last shaft of the previous section.

Rotary separator when cleaning licorice root works as follows.

The pile is fed to the first shaft with transporting and separating elements 2 of the first section. When the heap moves along the shafts of the section, the lump of soil is partially destroyed, and the thickness of the heap layer by decreasing the speed of rotation of the section shafts and removing the soil decreases. In this case, the speed of movement of the heap increases.

The last shaft 1 of the first section at high speed throws a heap on slowly

rotating separating drum 3. Under the action of inertial forces, a clod of soil slips between rods 6 and 7 inside the separating drum and out of it in the lower part, and licorice roots remain on the mesh surface of separating drum 3.

Due to inertial forces on the separating drum 3, the bulk of the soil is separated from the pile, so a pile with a small amount of lumps is fed to the second section. As the heap advances through the second section, the remaining clod comes into direct contact with the transporting and separating elements 2, while being actively destroyed and removed, and the clean roots are fed into the bunker.

Depending on the physicomechanical properties of the heap, more sections and drums can be installed in the rotor separator.

Claims (2)

1. A rotary separator consisting of parallel conveyor-separating shafts, combined in sections, equipped with a drive, characterized in that, in order to improve the quality of separation by intensifying the process of breaking up lumps of soil, separating drums are installed between the shafts. for their rotation at a speed less than the speed of rotation of the last shaft of the previous section. 2. A separator according to claim 1, characterized in that the conveying-separating shafts in the sections are driven to rotate with increasing speed in the heap supply direction.
