The opposite surfaces of the horizontal rod ends of the two connecting rods 74 are fixed with a plurality of limiting rods 75 that are slidably plugged with the mounting frame 14. By arranging the working plate 1, the screen frame 2, the mounting frame 14, the screen 3, the vibration motor 5 and a plurality of springs 6, the material can be filtered and screened. The mounting frame 14 and the screen 3 can be limited by the limiting mechanism 7, so as to facilitate the disassembly and assembly of the mounting frame 14 and the screen 3, and then facilitate the replacement of the mounting frame 14 and the screen 3, and also facilitate the cleaning of the screen 3.

The external collecting box is placed on the ground at a place corresponding to the position of the material trough on the top surface of the working plate 1, so that the screened material can be collected.

[0039] It is worth noting that the limiting mechanism 7 also includes a protective box 711 fixed on the surface of one side of one of the vertical plate ends of the fixed plate 71 away from the bidirectional screw rod 73, the limiting motor 78 is located inside the protective box 711, and the rotating shaft 79 passes through the surface of the side of the protective box 711 away from the bidirectional screw rod 73, which can protect the limiting motor 78 and thus extend the service life of the limiting motor 78.

[0040] It is worth mentioning that the longitudinal cross-sectional shape of the guide groove on the bottom surface of the transverse plate end of the fixed plate 71 is convex, and the shape of the guide block 76 is convex which is compatible with the shape of the guide groove on the bottom surface of the transverse plate end of the fixed plate 71.

[0041] Finally, it should be noted that the vibration motor 5, limit motor 78 and other components involved in the present invention are all universal standard parts or components known to technical personnel in this field. Their structures and principles are known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connections between the electrical components are completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0042] In the specific use process of this embodiment, when it is necessary to filter the material, firstly, the external collection box is placed on the ground at a place corresponding to the position of the material trough on the top surface of the working plate 1, and then the material is poured into the screen frame 2, and then the vibration motor 5 is started by the external PLC. After the vibration motor 5 is started, the screen frame 2 can be driven to vibrate. The screen frame 2 vibrates under the action of a plurality of springs 6 and a plurality of gaskets 8. The vibration of the screen frame 2 drives the screen 3 and the material to vibrate, and then the material can be filtered and screened. When the screening is completed, the vibration motor 5 is turned off by the external PLC;

[0043] When the screen 3 needs to be disassembled, replaced or cleaned, the limit motor 78 is first started through the external PLC. The output shaft of the limit motor 78 rotates to drive the rotating shaft 79 coaxially connected thereto to rotate. The rotation of the rotating shaft 79 drives the gear 710 coaxially fixed thereto on the same side to rotate. The rotation of the gear 710 drives another gear 710 meshing therewith to rotate. The rotation of the other gear 710 drives the rotating rod 77 coaxially fixed thereto to rotate. The rotation of the rotating rod 77 drives the rotating column 72 coaxially fixed thereto on the same side to rotate. The rotation of the rotating column 72 drives the bidirectional screw rod 73 coaxially fixed thereto to rotate. The rotation of the bidirectional screw rod 73 drives the two connecting rods 74 threadedly connected thereto to move away from each other. The connecting rod 74 is guided by the guide grooves on the guide block 76 on the same side and the bottom surface of the cross plate end of the fixed plate 71 The connecting rod 74 moves, thereby driving the movement of several limit rods 75 fixed thereto. When the limit rod 75 is completely separated from the through hole on the same side of the outer wall of the screen frame 2, the limit motor 78 is turned off by the external PLC, and then the installation frame 14 is moved by two push-pull rods 10. The installation frame 14 moves under the guidance of several sliders 9 and several slide grooves on the inner wall of the screen frame 2. When the installation frame 14 is completely separated from the screen frame 2, the disassembly of the installation frame 14 and the screen frame 2 is completed, so that the screen 3 can be cleaned, and it is also convenient to replace the screen 3, the installation frame 14, the two push-pull rods 10 and the several sliders 9 as a whole. Conversely, the new screen 3, the installation frame 14, the two push-pull rods 10 and the several sliders 9 can be installed.
