[0025] The opening and closing structure 9 includes three sliding rods 10, and the sliding rods 10 are all arranged on one side of the top of the main box 2. A triangular baffle 11 is slidably arranged between the outsides of the three sliding rods 10, and a linkage rod 13 is arranged at the rear of the triangular baffle 11. One end of the linkage rod 13 passes through one side of the top of the main box 2 and is rotatably arranged with a rotating shaft, and the rotating shaft is slidably arranged on the inner side of one end of the opening and closing plate 14.
[0026] Start the motor 3, so that the eccentric roller 4 acts on the screening plate 5 to make an up and down reciprocating motion in the vertical direction inside the main box 2, and the screening plate 5 moves synchronously with the guide rod 7, and then the guide rod 7 acts on the triangular push plate 15 for synchronous movement, and the triangular push plate 15 acts on the triangular baffle plate 11, so that the triangular baffle plate 11 performs a horizontal reciprocating sliding motion back and forth outside the slide rod 10. During the process, the triangular baffle plate 11 moves synchronously with the linkage rod 13, and then the linkage rod 13 acts on the opening and closing plate 14 through the rotating shaft to perform an opening and closing motion on the inner side of the feed port, and finally the opening and closing plate 14 opens and closes the feed port to avoid blockage of the feed port.
[0027] In this embodiment, the opening and closing plate 14 is rotatably arranged on the inner side of the feed port of the main box 2, and three springs 12 are arranged between the rear part of the triangular baffle 11 and the top side of the main box 2, and the three springs 12 are respectively adaptively matched with the positions of the three slide bars 10.
[0028] The second spring 12 plays an elastic supporting role on the triangular baffle 11 , so that the triangular baffle 11 rebounds to the initial position when the pressure of the triangular push plate 15 is lost.
[0029] In this embodiment, a triangular push plate 15 is connected between the tops of the two guide rods 7 on the same side, and the triangular push plate 15 and the triangular baffle plate 11 are adaptively matched.
[0030] The triangular push plate 15 acts on the triangular baffle 11 to make it slide back and forth outside the slide rod 10 .

During the process, the triangular baffle 11 synchronously moves with the linkage rod 13, and then the linkage rod 13 acts on the opening and closing plate 14 through the rotating shaft to perform opening and closing movements on the inner side of the feed port, and finally the opening and closing plate 14 opens and closes the feed port to avoid blockage of the feed port;
[0041] During the process, when the triangular push plate 15 acts on the triangular baffle 11 to slide toward the opening and closing plate 14 outside the sliding rod 10, the triangular baffle 11 synchronously moves with the serrated plate 17, so that the serrated plate 17 engages with the gear 19, and then the material limiting plate 18 rotates toward the top of the main box 2.
