Description

Technical Field

[0001] The utility model relates to the technical field of paddy and brown rice separators, in particular to an automatic cleaning mechanism for the screen of a gravity paddy and brown rice separator. Background Art

[0002] Rice, also known as paddy rice, is a food made from paddy through processes such as cleaning, hulling, milling, and finished product finishing. Paddy and brown rice refer to the paddy after removing the outer protective husk. Paddy and brown rice separation is the process of removing the paddy husk and cortex. Paddy grains consist of husk, cortex, embryo, and endosperm. The purpose of paddy processing is to separate the endosperm from other parts with the least degree of breakage to produce rice with good edible quality.

[0003] A gravity paddy and brown rice separator is a device that utilizes the differences in specific gravity, particle size, and surface friction coefficient between paddy and brown rice, and through the action of a reciprocating working plate with a double - inclined surface, increases automatic classification to separate paddy and brown rice. However, during the screening process of the existing paddy and brown rice separators, a large amount of rice husk debris is generated, and a certain amount of rice husk debris will remain on the surface of the sieve plate, even clogging the sieve holes of the sieve plate, affecting normal use. Generally, the sieve plate is disassembled for manual cleaning of the rice husk debris, but the time for disassembling and cleaning the rice husk debris is long, and the disassembly steps are relatively cumbersome, which will affect the working efficiency of paddy and brown rice separation.

[0004] Therefore, a new solution is needed to solve this problem. Content of the Utility Model
