Four corners of the upper surface of the mounting frame 311 are further respectively fixedly provided with springs 4, and the lower bottom surface of the sieve plate 32 is fixedly connected with the upper ends of the springs 4. And when the spring 4 is in a natural state, the sieve plate 32 is parallel to the belt surface of the feeding conveyor belt 2.
In addition, a vibration device 5 is also mounted on the upper surface of the mounting frame 311, and the vibration device 5 is positioned at one end of the mounting frame 311 far away from the upstream end 21 of the feeding conveyor belt 2.
Referring to fig. 4 and 5, the vibration device 5 includes two spaced apart clamp plates 51 fixed to the upper surface of the mounting frame 311 (see fig. 3), and each of the clamp plates 51 extends toward the screen plate 32. And a rotatable vibration wheel 52 is installed between the two clamping plates 51.
The vibrating wheel 52 includes a wheel body 521, the axis of the wheel body 521 is parallel to the axis of the rotating roller of the feeding and conveying belt 2, and the wheel body 521 is clamped between the two clamping plates 51 through the rotating shaft. Meanwhile, a pair of abutting blocks 522 is further fixedly disposed on the wheel body 521, and the two abutting blocks 522 are fixed on the arc surface of the wheel body 521 and are symmetrically disposed about the axis of the wheel body 521.
