Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and more specifically to a rice processing mill. Background Technology
[0002] Rice is a product of paddy rice, which is generally produced in high-yield areas of southern China. Therefore, people in southern China generally eat rice as their staple food. Rice can provide the energy that people need and is a very important food source. There are also many rice products. When processing rice, it is sometimes necessary to grind the rice into rice powder. Grinding rice requires a rice processing mill.
[0003] The shortcomings of existing technology: When existing rice milling machines are in operation, the operator usually pours a large amount of rice into the funnel box at one time for grinding. The large amount of rice accumulating in the box can easily cause the rice to clog the discharge port, which in turn affects the feeding rate during rice grinding and causes the rice grinding progress to be interrupted.
[0004] Therefore, there is a need to provide a rice processing mill to solve the problems mentioned above. Utility Model Content

[0020] The technical effects and advantages of this utility model are as follows:
[0021] 1. This utility model features a stirring assembly. Rice to be ground is poured into the feeding funnel through the inlet. Under the protection of the protective shell, the rotary motor is turned on. Supported by the U-shaped frame and the movable engagement of the collar, the main bevel gear rotates, which in turn drives the second set of bevel gears to rotate in the opposite direction to the first set of bevel gears. Under the limitation of the limiting block, the second stirring rod rotates in the opposite direction to the first stirring rod. This facilitates the second and first stirrers to rotate in opposite directions within the feeding funnel, stirring the rice. This ensures that the rice continuously enters the grinding chamber from the outlet at the bottom of the feeding funnel for grinding, without affecting the feeding efficiency of rice grinding.
[0022] 2. This utility model features a grinding mechanism. After rice enters the grinding box through a feeding funnel, the grinding motor is turned on, driving the first grinding roller connected to it to rotate. This, in turn, drives the main gear to rotate. Under the meshing action with the toothed belt, the toothed belt rotates, which in turn drives the secondary gear and the second grinding roller to rotate. This facilitates the grinding of rice by the rotation of the first and second grinding rollers. After grinding, the rice falls through the discharge pipe into the filter box in the collection assembly. Under the filtering action of the filter box, larger rice particles are collected in the filter box, while the qualified ground rice is collected in the collection box. Pulling the handle can remove the filter box for further grinding of the rice in the filter box. Attached Figure Description
