Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, in particular to a grain-rough separation screen. Background Art

[0002] Grain-husk separation refers to the process in which the rice husk falls off the brown rice after the rice is milled. At this time, the rice husk and brown rice are mixed together and need to be separated.

[0003] The Chinese utility model patent with the authorization announcement number "CN219334896U" is specifically "a grain-rough separation screen". Its beneficial effects record that "when feeding the grains, the operator can manually pull the handle and the fixed connection between the clamping rod. When the clamping rod slides inside the feeding mechanism, the clamping rod can drive the limit block to slide into the feeding mechanism. A number of clamping grooves are equidistantly arranged on the sealing plate. When the limit block is moved out of the clamping groove, the limit block can squeeze the compression spring sleeved on the clamping rod while sliding. When the limit block is separated from the sealing plate, it is convenient for the operator to adjust the position of the sealing plate, thereby preventing the sealing plate provided on the traditional separation screen from slipping easily during the feeding process."

[0004] However, in the above-mentioned device, brown rice and impurities will remain in the pores on the surface of the screen when it works for a long time, causing blockage on the surface of the screen, thereby reducing the screening efficiency and affecting the production efficiency. In addition, the screen is fixedly connected to the inner cavity of the machine body, and the worn and damaged screen cannot be replaced individually, thereby increasing the maintenance cost.
