Base frame 1 is a standard four-legged support, and fixed frames are added to the rear end and the left and right end support pieces. Base frame 1 is set low in front and high in back, matching the structure of vibrating table 2. Two elastic elements 4 are arranged on each of the two front end support pieces, and four elastic elements 4 are arranged on the welded plate connecting the two rear end support pieces, corresponding to the center of the rear end of vibrating table 2. Vibrating table 2 is a dustpan structure with an inclination, with an empty layer inside for mounting a cam mechanism. The bottom of vibrating table 2 is a slope, and the two sides are enclosed inner walls. Vibrating table 2 is connected to base frame 1 through elastic elements 4. Vibrating table 2 is provided with a transversely penetrating mounting groove 5 at the rear end, which is used to mount a self-vibrating device with components such as a vibrating body and a vibration exciter. Incoming material bin 3 is a funnel-shaped bin, with extended protective baffles 8 on both sides of the front end. Incoming material bin 3 is fixed to the side wall of vibrating table 2 in a suspended manner. A left-right reciprocating screen 6 is arranged in alignment below incoming material bin 3, which simultaneously contacts incoming material bin 3 and vibrating table 2, i.e. the screen 6 fills the gap between incoming material bin 3 and vibrating table 2, ensuring that the material will not spill out. The discharge opening of incoming material bin 3 is provided with an adjustable feeding baffle 7. Shaft support beams 9 are arranged between the protective baffles 8 of incoming material bin 3, with a perforated adjusting shaft seat 10 arranged in the center of the shaft support beam 9. The mounting surface of shaft support beam 9 is inclined backward, and the feeding baffle 7 is hinged with an adjusting beam 11. The adjusting beam 11 is provided with an array of transversely penetrating holes along its length direction, and the penetrating holes of adjusting shaft seat 10 are connected to different penetrating holes on adjusting beam 11 to realize the opening and closing degree of feeding baffle 7, i.e. to change the rotation angle of feeding baffle 7.

[0024] In use, the material enters the main area of the incoming material bin 3, rolls down along the slope of the vibrating table 2, and is limited to flow through by the feeding baffle 7, and the feeding speed is adjusted by adjusting different holes. At the same time, the adjusting motor is started to drive the cam piece 20 to rotate, the ball block 21 at the other end of the cam piece 20 slides up and down in the movement groove 16, so that the cam piece 20 moves in a certain area.
