Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The embodiments of the present application provide a screening device for grain processing, which solves the problem that grains with smaller particle sizes block the screen and affect the next batch of grain processing during grain processing and screening.

The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems. The general idea is as follows: due to the fixing of the screen, it is not easy to clean when the grain is stuck in the screen hole. The grain shakes down, and the sieved grain is collected at the same time. The merging of the two screens is realized through the power-on and power-off of the electromagnet, and the vibration effect is more obvious by using the spring.

In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

A screening device for grain processing, comprising a box body 1 and legs 5 fixedly connected to the four corners of the bottom of the box body, a box cover 2 is hinged on one side of the top of the box body 1, and a feeding port 3 is fixedly connected to the top of the box cover 2; Electric telescopic rods 6 are fixedly connected to the left and right side walls of the interior of the box body 1, and the output ends of the two electric telescopic rods 6 are fixedly connected to the same coaming frame 8, and the bottoms of the left and right ends of the coaming frame 8 are rotatably connected to screens 9 , the right end of the bottom of the screen 9 on the left is fixedly connected with an electromagnet 10, and the left end of the bottom of the screen 9 on the right is fixedly connected with an iron block 11; , The bottom end of the box body 1 is fixedly connected with a discharge port 4 .
