Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice impurity screening device. Background Art

[0002] Rice, also known as rice, is a food made from rice grains after cleaning, husking, milling, and finishing. There are many ways to eat rice. People usually use stewing or steaming to make rice, or cook rice into porridge.

[0003] In application number: CN202320194428.9, a rice impurity screening device with a material balancing function is disclosed. The rice slides down to the four sides in the material balancing tube and falls onto the screening net through the guide head. The material balancing tube can shake under the action of the spring to speed up the falling speed of the rice to avoid blockage. The rice falls evenly on the screening net at different positions for screening, and the overall screening effect is improved. However, the above design still has shortcomings. A feed pipe is provided at the top of the screening box, but the feed pipe has a single structure and cannot temporarily store the rice, and cannot pre-treat the rice, thereby reducing its practicality.

[0004] For this reason, we propose a rice impurity screening device. Utility Model Content

[0008] By adopting the above technical solution, the second motor drives the rotating shaft to rotate, and the rotating shaft drives the discharge rod to rotate, so that the rice can be stirred, which is convenient for the discharge of rice located at the bottom of the screening box. The design of the baffle facilitates the discharge of impurities filtered out of the rice.

[0009] Specifically, the installation box is a rectangular frame structure, the installation box is connected to the discharge port, a collecting box is movably inserted at one end of the installation box away from the screening box, and a baffle is movably inserted at the top of the installation box.
