Grain processing rice milling device

Abstract

The invention belongs to the technical field of rice processing devices, and particularly discloses a grain processing rice milling device. The grain processing rice milling device comprises a feedingmechanism, a rice milling mechanism, a rice discharging mechanism, a bran discharging mechanism and a transmission mechanism, wherein the feeding mechanism comprises a conveying box and a feeding hopper, and the feeding hopper communicates with the conveying box; the rice milling mechanism comprises a mounting box and a milling roller, a spiral blade is arranged on the portion, located in the conveying box, of the milling roller, a sieve and a milling cutter are arranged in the mounting box, and a gap is formed between the sieve and the milling roller; the rice discharging mechanism comprisesa rice discharging box, a material blocking plate is arranged in the rice discharging box in a sliding fit mode, a discharging opening is formed in the bottom of the rice discharging box, an adjusting screw is arranged at the end, away from the mounting box, of the rice discharging box, an elastic piece is arranged between the adjusting screw and the material blocking plate, and the material blocking plate can block the discharging opening when the elastic piece is in a natural state. The rice yield can be increased, and the amount of unpeeled rice contained in rice grains is reduced.

Description

technical field [0001] The application of the present invention belongs to the technical field of rice processing equipment, and specifically discloses a rice milling equipment for grain processing. Background technique [0002] The rice mill is a processing equipment that uses mechanical force to peel rice, thereby processing it into rice grains and bran powder, and can separate rice grains and bran powder. [0003] In the prior art, the invention patent with publication number CN109225389A discloses a rice milling machine, which includes a feeding hopper, a rice milling device, a rice bran separation device, a rice grain storage device and a bran powder storage device; the rice bran separation device includes a rice bran separation device Separation box, rice sieve, blower, screw discharger, screw mixer and exhaust fan; the rice sieve is arranged obliquely in the rice bran separation box; Facing into the rice bran separation box; the screw discharger is arranged at the ri...

AI Technical Summary

Problems solved by technology

Although the above-mentioned patent can realize the peeling of rice, and can separate the rice grains and bran powder formed after peeling, the above-mentioned patent has a poor effect on the peeling of rice, and does not control the discharge speed and amount of rice grains. It is easy to cause part of the rice to be discharged from the rice bran outlet before it has been peeled, resulting in more unpeeled rice in the collected rice grains, which reduces the rice yield

[0005] In addition, in the process of rice milling and peeling in the above-mentioned patent, the gap between the outer wall of the rice milling roller and the rice milling box cannot be adjusted, which is inconvenient to adjust and control the pressure on the rice. If the gap between the outer wall of the rice milling roller and the rice milling box If the gap is too small, the pressure on the paddy will be too large, resulting in incomplete rice grains after peeling and more broken rice. If the gap between the outer wall of the rice milling roller and the rice milling box is too large, the pressure on the paddy will be less If it is too small, it is easy to cause insufficient peeling of the rice, resulting in more unpeeled rice in the rice grains
