Efficient, stable and full-automatic rice husking machine

Abstract

The invention relates to the technical field of agricultural processing equipment, and discloses an efficient, stable and full-automatic rice husking machine. The machine comprises a shell, a bran outlet and a rice outlet. A connecting shaft and an upper fixing piece are fixedly installed inside the shell, and the shell is movably connected with a conical grinding sieve through the connecting shaft and the upper fixing piece. According to the efficient, stable and full-automatic rice husking machine, the grinding gap and the grinding pressure can be conveniently adjusted by adjusting the height of the grinding sieve, meanwhile, a sliding block tends to slide outwards along with increase of the speed and increase of centrifugal force, the grinding pressure is reduced, in other words, the grinding pressure is reduced while the speed is increased, the rotating speed and the grinding pressure are in a corresponding relation, and then less broken rice is produced; and the grinding pressurecan be adjusted through the attraction of an electromagnet, the use flexibility is improved, secondly, because high pressure is generated due to air blowing of an air blowing pipe, negative pressure is generated at an outlet, friction force is increased due to the pressure difference of air, and moisture can be taken away due to increase of air motion, and the rice bran is kept dry.

Description

technical field [0001] The invention relates to the technical field of agricultural processing equipment, in particular to an efficient and stable full-automatic rice milling machine. Background technique [0002] The main structure of the rice mill includes a roller, a rice sieve and a rice knife. The roller plays the role of grinding the skin of brown rice, and the rice knife appropriately increases the pressure during milling. [0003] During the rolling process, the rice mill controls the rice grain and milling time by controlling the outlet flow rate, and then adjusts the whitening quality. During this process, the gap and pressure in the milling space are difficult to adjust, and it is easy to cause broken rice. Secondly, During the milling process, some rice bran cannot be discharged in time, and they are mixed together, which increases the rotational resistance of the roller, lowers the milling quality, and increases energy consumption. At the same time, some rice br...

[0003] During the rolling process, the rice mill controls the rice grain and milling time by controlling the outlet flow rate, and then adjusts the whitening quality. During this process, the gap and pressure in the milling space are difficult to adjust, and it is easy to cause broken rice. Secondly, During the milling process, some rice bran cannot be discharged in time, and they are mixed together, which increases the rotation resistance of the roller, lowers the milling quality, and increases energy consumption. At the same time, some rice bran is repeatedly milled, which further increases the energy consumption. can

[0004] Secondly, when milling, if the moisture content of the rice grain is high, the rice bran will have higher viscosity, and it will easily adhere to the rice sieve and roller, reducing the quality of milling. It needs to be cleaned regularly. During the process, due to friction and heat, the rice grains will have higher heat, and before the rice grains and rice bran are separated, heat dissipation will be affected, which will further increase the temperature of the rice grains, increase the nutrient loss of the rice grains, and also reduce the heat dissipation of the rice grains. storage time
