The bottom of the adjusting block 2 is fixedly connected with a rectangular frame 21, two ends of the rectangular frame 21 are in sliding fit with corresponding sliding grooves 42, and the end faces of the rectangular frame 21 are tightly attached to the inner walls of the sliding grooves 42. The sliding block 14 is slidably fitted in the rectangular frame 21, and the top surface of the sliding block 14 is not higher than the top surface of the rectangular frame 21, so as to prevent the sliding block 14 from interfering with the adjusting block 2 during the moving process.

The power mechanism 1 operates according to the following principle: the motor 11 drives the chain wheel 12 connected with the motor, and the other chain wheel 12 rotates along with the motor under the action of the chain 13; the sliding block 14 moves along with the track of the chain 13, and because the sliding block 14 is rotatably connected to the chain 13, the sliding block 14 is slidingly matched in the rectangular frame 21, and the rectangular frame 21 is slidingly matched in the sliding groove 42, the sliding block 14 causes the rectangular frame 21 to reciprocate along a straight line, that is, the adjusting block 2 reciprocates along the straight line.

In this embodiment, two screening assemblies 3 are provided, each screening assembly 3 includes a feed box 31, a screen tray 32 and a straight rod 33, in this embodiment, one feed box 31 is distributed on the outer side of the slide 4, and the other feed box 31 is distributed on the end of the slide 4, and of course, the distribution positions of the two feed boxes 31 may also have other options, such as symmetrically distributed on the outer sides of the two slides 4 or symmetrically distributed on the end of the two slides 4.
