6. The grain impurity removing and screening device according to claim 1, wherein: the feeding hole is formed in the upper side of the position of the first cavity in the outer frame and communicated with the feeding hopper, and the discharging hole is formed in the bottom of the position of the second cavity in the outer frame.
7. The grain impurity removing and screening device according to claim 1, wherein: and a groove matched with the air gun panel is formed in the inner surface of the outer frame.
8. A working method of grain impurity removal screening equipment is characterized in that: the method comprises the following steps:
step S1: pouring the mixture of the harvested grains and the like from a feeding funnel, adjusting the pouring amount of the feeding funnel according to the specification size of the feeding funnel, filling the feeding funnel, and finishing the preparation work;
step S2: after the grain mixture in the feeding hopper is filled, the grain mixture enters the first cavity through the feeding hole in the outer frame, then the crushing assembly is used for crushing, and the mixture after crushing enters the second cavity under the action of the auger rod;
step S3: after entering the position of the second cavity, the grains are blown up through the lower wind blades, and because the shells of the grains are light, the shells are blown into the cavity of the second cavity by the lower wind blades, then the pneumatic pump is started to spray the grains onto the sieving plate, and the grains enter the inner box body after being filtered and sieved;
step S4: grain particles fall into the subassembly that sieves from driving motor play on, the lower driving motor in the subassembly that sieves afterwards starts, and lower driving motor drive drives and rotates the wheel rotation, rotates the wheel and rotates and drive the connecting rod and swing, will sieve the panel drive afterwards and shake along the direction of gyro wheel, and the millet material is shaken from the gyro wheel on the unloading slide.
9. The working method of the grain impurity removing and screening equipment as claimed in claim 8, wherein the working method comprises the following steps: the smashing processing performed by the smashing component in the step S2 specifically includes the following steps: the inner motor is started to drive the first bevel gear to rotate, the first bevel gear is meshed with the second bevel gear to further drive the smashing rod to rotate, meanwhile, the distance between the two sliding blocks is changed through driving of the hydraulic cylinder, the rotating angle of the rotating connecting rod is changed, the position of the movable base plate on the guide groove block is correspondingly changed, and the height position of the movable base plate is adjusted.
