Automatic potato screening grading device

Abstract

The invention relates to the technical field of potato screening grading devices, and discloses an automatic potato screening grading device. The automatic potato screening grading device comprises ascreen assembly, a supporting assembly, a cleaning assembly and a uniformly-stirring assembly. The screen assembly comprises a screen box, a discharging hopper, an auxiliary overturning cover, a fixedrail, a dustproof box cover, a screen, a feeding hopper and a vibrating motor. An accommodating cavity is formed in the screen box, and the discharging hopper is positioned at the bottom end of the right side of the screen box and is fixedly connected with the screen box. The effective screening area of the screen is increased so that potatoes cannot be stacked, and the screening efficiency of the potatoes is improved. A screw rod is arranged in a machine body, a fixed seat and a cleaning brush are arranged on the screw rod, and the screw rod is used for driving the cleaning brush to performlinear reciprocating motion on the screen to clean the screen, so that impurities attached to the screen in a clamped mode are removed; and meanwhile, a cleaning overturning cover is arranged on the screen box, so that the cleaning brush is more convenient to replace, the service efficiency of the screen is improved, and the service life of the screen is prolonged.

Description

technical field [0001] The invention relates to the technical field of potato sieving and grading devices, in particular to an automatic potato sieving and grading device. Background technique [0002] During the use of the original potato screening and grading machine, when the potatoes enter the screen through the feed hopper, most of the input potatoes are concentrated in the middle of the screen, resulting in stacking of potatoes in the middle and only a small amount of potatoes on both sides. The uneven distribution of potatoes will reduce the effective screening area of ​​the sieve, and after the sieve has been working for a period of time, debris may be stuck in the mesh holes. If it is not cleaned in time, the potatoes will not be sieved evenly and fall. Further reduce the screening efficiency of the screen. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a potato automatic sieving and grading device, ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a potato automatic sieving and grading device, which has the advantages of long service life, high working efficiency, and good sieving efficiency, and solves the problem that the original potato sieving and grading machine is in use. When entering the sieve through the feed hopper, most of the input potatoes are concentrated in the middle part of the sieve, resulting in stacking of potatoes in the middle and only a small amount of potatoes on both sides. The uneven distribution of potatoes will reduce the effective screening of the sieve. After the screen has been working for a period of time, debris may be stuck in the mesh. If it is not cleaned in time, the potatoes will not be evenly screened and fall, which will further reduce the screening efficiency of the screen.
