The number of supporting legs 2 can be increased in groups according to actual conditions, so that it has an appropriate supporting force on the top, and the receiving bin 3 is used to receive items that have passed the screening by the screen 8. At the same time, the receiving bin 3 is an existing receiving bin, and its material and shape can be replaced according to the screening items used, thereby improving the degree of protection for the screened items.

[0025] In this example, see Figure 1 and Figure 5The power assembly is composed of a drive motor 41, a connecting rod 42 and a connecting piece 43. The drive motor 41 is fixedly mounted on the right side of the upper end surface of the first fixed plate 1. At the same time, the output end of the drive motor 41 is fixedly connected to the connecting rod 42. The middle part of the connecting rod 42 is fixedly mounted with a connecting piece 43. At the same time, the shape of the connecting piece 43 is a circular ring with a raised top. The connecting piece 43 is engaged with the connecting plate 10. When in use, the installation of the drive motor 41 can be fixed by using existing rivets or screws. The connection method of the drive motor 41 and the connecting rod 42 adopts the existing electric The machine connection method can be used. Turning on the drive motor 41 can drive the connecting rod 42 to rotate, so that the connecting rod 42 can drive the connecting piece 43 to rotate. Due to the shape of the connecting piece 43, when the connecting piece 43 uses its own convex state to drive the screen body shell 7 to reciprocate through the connecting plate 10, the left end of the connecting rod 42 is connected to the external limit block, so that the external limit block provides a limiting and stabilizing function for the left end of the connecting rod 42, so that the connecting rod 42 has better stability during operation, thereby strengthening the connectivity between the connecting piece 43 and the connecting plate 10.

When in use, after the screen housing 7 makes itself reciprocating through the connecting plate 10, the screen housing 7 will drive the connecting block 111 to move synchronously. The connecting block 111 is engaged with the second fixed plate 5 inside through the connecting shaft 112, thereby providing a support function for the screen housing 7. The connecting shaft 112 also provides a limiting function for the screen housing 7 through the connecting block 111. At the same time, the connecting block 111 is tightly pressed against the strong spring 63 through the connecting rod 113, so that when the connecting block 111 drives the connecting rod 113 to move, the strong spring 63 will reset the connecting rod 113 through its own characteristics. The selection of the strong spring 63 can be appropriately adjusted according to the actual screened items and the pressure it bears, so as to ensure that the strong spring 63 meets the above conditions during use.

[0027] Example 2: Please refer to Figure 1 、 Figure 2 and Figure 3 , a screen 8 is fixedly installed in the middle of the screen shell 7, and support bars 9 are fixedly installed on the upper end surface of the screen 8 at equal intervals, and the left and right end surfaces of the support bars 9 are fixedly connected to the inner side of the screen shell 7.
