Description

Technical Field

[0001] The utility model relates to the technical field of flat rotary screens, in particular to a rice processing and grading flat rotary screen. Background Art

[0002] The flat rotary screen is a screening device that screens rice by vibration and rotation, so that rice with the same particle size is gathered together. The rice processing and grading flat rotary screen can improve the quality of rice, and at the same time improve production efficiency and reduce costs. The rice processing and grading flat rotary screen is widely used in the rice processing industry and can help manufacturers provide better quality rice products.

[0003] According to a white rice grading flat rotary screen for rice processing disclosed in the national patent network (authorization announcement number: CN217411437 U), "the utility model discloses a white rice grading flat rotary screen for rice processing, including a base, a support plate is fixedly connected to the top of the base, two slide grooves are arranged inside the support plate, two slide rails are slidably connected to the inside of the two slide grooves, and the tops of the two slide rails are slidably connected to the screen through pulleys. The outer surface of the support plate is fixedly connected to a bracket, and a motor is fixedly arranged on the outer surface of the bracket. The output shaft of the motor is connected to a half gear through a coupling transmission. The outer surface of the support plate is fixedly connected to a reset spring, and one end of the reset spring is fixedly connected to the outer surface of the screen and is fixedly connected to a rack plate. The motor drives the half gear to rotate. According to the structure of the half gear, the half gear will intermittently mesh with the rack plate during the rotation process, thereby driving the rack plate to move. Under the elastic force of the reset spring, the displaced rack plate will be reset, and then the rack plate drives the screen to move back to the original position to achieve the effect of screening materials."

[0004] Although the device separates rice by size and improves the screening efficiency, dust and impurities may adhere to the surface of rice grains during the processing and storage of rice. The device does not take into account the problem that dust is easily generated during the screening process, which easily causes the screened rice to carry a large amount of dust.
