The second vibrating screen 303 is installed on one card plate 301. The first vibrating screen 302 is installed at one end of the card plate 301. The storage box 304 is arranged inside the support component 1. The second stepper motor 305 is installed on the support component 1. The output end of the second stepper motor 305 is fixedly connected to the second screw rod 306, and the second screw rod 306 is matched with the storage box 304. After the screening is completed, the door panel 104 can be opened, the first vibrating screen 302 and the second vibrating screen 303 can be removed, and the food impurities inside can be cleaned.

[0026] The use method and advantages of the utility model: When the screening and impurity removal equipment is in use, the working process is as follows:

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using the screening and impurity removal equipment, first, the electrical equipment in the screening and impurity removal equipment is connected to an external power supply, the equipment is installed at a designated location of a grain processing site, the first vibrating screen 302 and the second vibrating screen 303 are opened, and the grain is poured into the interior of the barrel body 201 through the feed hopper 205, and then the first stepper motor 203 is turned on, so that the output shaft of the first stepper motor 203 drives the first screw rod 204 to rotate to perform feeding work, and the grain falls onto the second vibrating screen 303 for primary impurity removal, and the generated impurities fall into the processing tank of the second vibrating screen 303 through the sieve holes for storage, and then the preliminarily screened grain enters the first vibrating screen 302 under the influence of gravity and vibration for secondary screening to ensure the effect of screening and impurity removal, and then the screened grain falls into the interior of the storage box 304, and then is beaten.
