[0036] Working principle:

[0037] The first step is to slide the sliding block 18 from right to left, and the sliding block 18 drives the insert inside the slotted card block 19 to slide from right to left. When the insert leaves the square groove of the side wall of the T-shaped card block 17, the cover plate 12 is flipped from front to back to open it, and the square screen 33 is placed inside the hollow rectangular parallelepiped 25, so that the L-shaped card block 34 is stuck on the top of the hollow rectangular parallelepiped 25, and then the feed to be screened is poured into the square screen 33, and then the cover plate 12 is flipped from back to front to close it, and the sliding block 18 is slid from left to right, and the sliding block 18 drives the slotted card block 19 to slide. The insert at the top slides from left to right, so that the insert is inserted into the square groove of the side wall of the T-shaped block 17, and the first cylinder 14 is started. The first cylinder 14 drives the first hydraulic rod 15 to perform rapid left-right reciprocating motion, the first hydraulic rod 15 drives the first connecting rod 16 to perform rapid left-right reciprocating motion, the first connecting rod 16 drives the hollow rectangular parallelepiped 25 to perform rapid left-right reciprocating motion, the hollow rectangular parallelepiped 25 drives the L-shaped block 34 to perform rapid left-right reciprocating motion, and the L-shaped block 34 drives the square screen 33 to perform rapid left-right reciprocating motion, thereby screening the feed.

[0038] In the second step, when the square screen 33 is blocked by feed during screening, the second cylinder 28 is started, and the second cylinder 28 drives the second hydraulic rod 29 to perform rapid up and down reciprocating motion, and the second hydraulic rod 29 drives the percussion hammer 31 to perform rapid up and down reciprocating motion, so that the percussion hammer 31 knocks on the square screen 33, so that the feed blocked in the square screen 33 is knocked into the inside of the square screen 33. When the screening is completed, the rotating block 22 is rotated away from the side of the surrounding edge strip 21, and then the second connecting rod 23 is rotated clockwise, the second connecting rod 23 drives the third connecting rod 24 to rotate clockwise, the third connecting rod 24 drives the second cylinder 28 to rotate clockwise, the second cylinder 28 drives the second hydraulic rod 29 to rotate, and the second hydraulic rod 29 drives the percussion hammer 31 to rotate clockwise, so that the feed remaining on the top of the second cylinder 28 flows out from the discharge port at the bottom.

[0039] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
