[0024] As shown in Fig. 3 , the transmission mechanism comprises two groups of support connecting rods 32, one end of the support connecting rod 32 is hinged to the screen body 31, and the other end is hinged to the rack 1. Specifically, the number of the support connecting rods 32 in each group is at least two, and the support connecting rods 32 in the same group are arranged in parallel. The number of the support connecting rods 32 is at least four, and the vibrating screen 3 is stable and reliable.

Each vibrating plate 4 is provided with two discharge channels. The two hoppers 2 are integrally arranged, and the feed inlets of the two hoppers 2 are connected. The dual arrangement of the vibrating screen 3 and vibrating plate 4 can better meet the requirements of chain assembly, while also making the spatial layout more compact and saving space.

[0028] The cam 34, drive link 33, and support link 32 form a crank-rocker mechanism. The vibrating screen 3 is floatingly mounted on the frame 1 via two sets of support links 32. During loading, chain plates are poured into the hopper 2 and fall from the hopper 2's discharge port into the storage chamber of the vibrating screen 3. The driver 35 rotates the cam 34.
