SU1681983A1 - Apparatus for removal of impurities from roots - Google Patents

Abstract

The invention relates to equipment for the mechanical classification of materials in the process of post-harvest processing of root crops (CCP) in agriculture and in CCP processing plants. The purpose of the invention is to improve the quality of the separation of impurities from the CCP. The device contains a loading conveyor, a screening surface in a row and parallel to the cylindrical bar tines (B) 2 mounted on the axes for rotation in one direction, the diameter of which increases in the course of the CCP movement. The bars in the adjacent B 2 installed at opposite angles to the generator B 2 angles of inclination. The rotation axes 3B 2 are shifted in one direction from their hermetic axes 4. The conveyor belt is fed to B 2. Due to the displacement of the axes 3 from the arm 4, a pulsating change in the speed of movement of the PDC and their shaking is provided. This provides intensive separation of impurities. 2 Il. y o o 00 h 00 so

Description

The invention relates to the mechanical classification of materials and is intended for the post-harvest processing of root and tuber crops and can be used in agriculture, in the food industry.

The purpose of the invention is to improve the quality of the separation of impurities from the roots of the tubers.

FIG. 1 is a schematic diagram of the device; 2 shows the arrangement of the tines in three positions.

A device for separating impurities from root and tuber crops contains a loading conveyor 1, a series of parallel rotating water directions of cylindrical bar beaters 2 mounted on axes 3.

The installation diameter of the bars of the beaters 2 increases in the course of the movement of the tubers. The bars in the adjacent beaters 2 are set at angles of inclination opposite to the generator of the beaters. The rotation axes 3 of the tines are shifted in one direction relative to their hermetic axes 4, and the magnitude of the shift for all tines is the same. The device also has a conveyor 5 for transporting peeled root and tuber crops and a bunker 6 for impurities.

A device for separating impurities from the root and vegetable crops works as follows.

Koroblubnefrub loading conveyor 1 serves on the rod beaters 2,

where the separation of root crops from impurities and plant residues. Since the axes 3 of rotation of the rod beaters are displaced relative to their geometrical axes 4, a pulsating change in the speed of movement of the tubers and the shaking is provided. In this case, there is an intensive separation of impurities that spill into the gaps between the tines and rods of the tines and enter the impurity bin 6, and the tubers enter the conveyor 5.
