In a specific driving process, when the cylinder 443 pulls the first connecting rod 4421 and/or the second connecting rod 4422 backwards, the driving rod 442 bends or folds or deforms to a certain degree, the longitudinal width of the driving rod 442 becomes smaller, and the mounting plate 431 is pulled downwards, so that the anti-blocking structure 403 is separated from the bracket 402; on the contrary, when the cylinder 443 pushes the first connecting rod 4421 and/or the second connecting rod 4422 forward, the driving rod 442 bends or folds, the longitudinal width of the driving rod 442 increases, and the mounting plate 431 is pushed upward to connect the anti-blocking structure 403 with the bracket 402, so that the driving structure 404 has good stability, the driving function is directly effective, and the material switching or screening can not be interfered.

As shown in fig. 9, as another embodiment of the present invention, a cylinder 443 is provided with a connecting shaft 4431, the front end of the connecting shaft 4431 is connected to the intersecting ends of the first connecting rod 4421 and the second connecting rod 4422, the rear end of the connecting shaft 4431 is connected to the cylinder 443, and the first connecting rod 4421 and the second connecting rod 4422 are folded or stretched by the driving of the connecting shaft 4431. Specifically, in this embodiment, the front portion of the cylinder 443 is provided with a connecting shaft 4431, the connecting shaft 4431 can move back and forth according to the driving of the cylinder 443, the connecting shaft 4431 not only has a function of pulling the first connecting rod 4421 and the second connecting rod 4422, but also has a function of supporting and connecting the first connecting rod 4421 and the second connecting rod 4422, when the connecting shaft 4431 moves back, the connecting shaft 4431 drives the intersecting ends of the first connecting rod 4421 and the second connecting rod 4422 to move back, so that the first connecting rod 4421 and the second connecting rod 4422 are in a partially folded state, the first connecting rod 4421 pulls the mounting plate 431 downwards, and the anti-blocking structure 403 is separated from the bracket 402; on the contrary, when the connecting shaft 4431 moves forward, the connecting shaft 4431 drives the intersecting ends of the first connecting rod 4421 and the second connecting rod 4422 to move forward, so that the first connecting rod 4421 and the second connecting rod 4422 are in a stretching state, the first connecting rod 4421 pushes the mounting plate 431 upward, and the anti-blocking structure 403 is connected with the bracket 402. Therefore, the air cylinder 443 is only needed to drive the first connecting rod 4421 and the second connecting rod 4422 to be folded or stretched, so that the anti-blocking structure 403 is further driven to be separated from or connected with the bracket 402, the structural design is reasonable, and the driving mode is simple and efficient.

As another embodiment of the present invention, as shown in fig. 9, a protective cover 445 is provided under the bracket 402, one end of the protective cover 445 is located at the front of the connection chamber 421, and the other end is connected to the front frame 44 in an oblique direction. In this embodiment, a protective cover 445 is arranged below the first frame 4021 of the bracket 402, the protective cover 445 is arranged at the front part close to the connecting chamber 421, and the other end of the protective cover is connected with the front frame 44 in an inclined downward direction to protect the front frame 44 and the bracket 402, in the actual operation process, when materials are screened downward, the materials easily collide with the frame 44, so that the frame 44 is damaged for a long time, the stability is poor, and the materials are also damaged.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.

In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the scope of the present invention.
