Rice milling device

Abstract

The invention provides a rice milling device with the better chaffhusk separating effect and the low rice broken rate. The rice milling device comprises a driving part and a rice milling box, a rice milling part connected to an output shaft of the driving part is arranged in the rice milling box, the rice milling box comprises a horizontal section and a vertical section, an opening is formed in the side wallof the side, away from the driving part, of the vertical section of the rice milling box, a venturi tube is arranged on the side, away from the driving part, of the rice milling box, the venturi tube abuts against the rice milling box, and a throat tube of the venturi tube faces toward the opening; the diffusion section of the venturi tube communicates with a pneumatic motor, an outputshaft of the pneumatic motor is connected with a crank sliding block mechanism, a piston plate located on the lower part of the opening is vertically and slidably connected into the vertical section of the rice milling box, filter holes are formed in the piston plate, and the piston plate is connected with the crank sliding block mechanism. According to the scheme, the rice milling device is usedfor rice milling, thus the obtained rice can contain little chaff husk, and the rice broken rate is low.

Description

technical field [0001] The invention relates to the field of rice milling, in particular to a rice milling device. Background technique [0002] China is known as a "big rice planting country", and rice is the staple food in most parts of my country. Rice is made by milling and husking the grains, sieving and sorting the bran. In the vast rural areas, the traditional rice milling operation is to send the grains to the processing point for centralized shelling, and then wind selection to remove the bran to obtain rice. But the quality of rice in the rice produced by this traditional rice milling machine is poor, and the rice yield is low. [0003] Existing rice milling machine comprises frame, feeding hopper, machine head, head frame, blower fan, protective cover, motor; Inside the frame; the machine head part includes pulleys, feeding bearing body, rice milling shaft roller, cylindrical rice sieve, rice milling outdoor cover, bucket seat, and rice output adjustment device...

AI Technical Summary

Problems solved by technology

However, in the process of rice milling, the rice milling shaft roller will squeeze the rice, which will cause some of the rice to form broken rice after being squeezed, so that the broken rice will be produced together with the finished rice, while the existing method After finishing the rice milling process, it is necessary to add a broken rice sieving device, which prolongs the time required for rice processing and reduces work efficiency
