High-strength rice husking machine sieve

Abstract

The invention discloses a high-strength rice husking machine sieve, and relates to the technical field of rice husking machine sieves. The high-strength rice husking machine sieve comprises a machinesieve main body, first sieve holes and a first limiting groove are formed in the outer surface of the machine sieve main body, first reinforcing ribs are installed in the interior of the first limiting groove, second limiting grooves are formed in an inner ring of the machine sieve main body, second reinforcing ribs are installed in the interior of the second limiting grooves, an installation groove is formed in the top of the machine sieve main body, an auxiliary machine sieve is installed in the installation groove, the top of the auxiliary machine sieve is connected with an air inlet pipe,and second sieve holes and third sieve holes are arranged on the outer surface of the auxiliary machine sieve in a penetrating mode. According to the high-strength rice husking machine sieve, a user rotates the auxiliary machine sieve in the installation groove according to the diameter of rice bran needing to be processed, when the third sieve holes in the auxiliary machine sieve coincide with the first sieve holes, the machine sieves operate normally, and when the second sieve holes in the auxiliary machine sieve coincide with the first sieve holes, the area of the sieve holes of the machinesieves is decreased, the machine sieves are suitable for small-diameter rice bran, and after adjustment, a rice sieve is installed in a sieve frame for fixing.

Description

technical field [0001] The invention relates to the technical field of rice mill sieves, in particular to a high-strength rice mill sieve. Background technique [0002] The rice mill is mainly composed of a fixed wrench, a tightening nut wrench, a brush, a lower hopper, a grinding wheel, a wire brush, etc., and uses the mechanical force generated by the mechanical equipment to peel and whiten the brown rice. The mechanical equipment used is called rice milling. The rice milling machine is manufactured by Hunan Zhengde Peeling Machinery Factory through unremitting efforts. The structure and process of the rice milling machine are simple, easy to operate and maintain. Although the structural form, working mechanism and technical parameters are different, the structural elements are basically the same. Combined rice milling machine is mainly composed of hopper, casing (square box, round box), rice roller, rice sieve, rice knife and frame, rice outlet parts, separation parts (in...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength rice milling machine sieve to solve the above-mentioned background technology that the size of the aperture on the sieve is often fixed, and only the sieve is replaced for rice bran of different thickness, which seriously affects the work efficiency. The cross section of the mesh is rectangular, so the broken rice is easy to block when passing through the mesh, and the strength of the machine sieve is small, which will also affect the use of the machine sieve.
