The end of the movable rod 32 away from the turntable 31 is rotatably installed on the side of the slider 29. Two mutually meshing first bevel gears 13 are arranged on the outside of the screening box 2, one of which is rotatably installed on the side of the screening box 2, and the side of the first bevel gear 13 is fixedly installed at the center of the end face of the third rotating rod 36 through the connecting shaft, and the first rotating rod 12 is horizontally fixedly installed on the side of the other first bevel gear 13. A limiting block is fixedly installed on the side of the screening box 2. The surface is rotatably installed inside the limit block, and the side of the screening box 2 is rotatably installed with a first gear 9 meshing with each other, one of the first gear 9 sides is fixedly installed on the corresponding side end of the adjustment plate 18 through a connecting shaft, and the side of the first gear 9 and the end of the first rotating rod 12 away from the first bevel gear 13 are fixedly installed with a second pulley 10, and the two second pulleys 10 are sleeved with a second belt 11, and the side of the first gear 9 is rotatably provided with a first belt 7, and the first belt 7 is provided with first pulleys 8 at both ends, one of the first pulleys 8 is fixedly installed at the center of the corresponding side of the first gear 9, and the other first pulley 8 is rotatably installed on the outside of the screening box 2, and the side of the first pulley 8 is fixedly installed on the corresponding side end of the adjustment plate 18 through a connecting shaft;

[0043] Preferably, when there are a lot of large pieces of material piled up on the first mesh plate 21, the second mesh plate 22 can be automatically moved according to its own gravity to expand the holes between the first mesh plate 21 and the second mesh plate 22, so that the large pieces of material on the first mesh plate 21 fall down, thereby avoiding the first mesh plate 21 being blocked and causing the first mesh plate 21 to be unable to continue filtering.

[0044] Please refer to the attached Figure 1 -Attached Figure 4 In a preferred embodiment, the sealing assembly includes: a sealing plate 19, two sealing plates 19, the two sealing plates 19 are symmetrically arranged inside the screening box 2, two symmetrically arranged second motors 15 are installed on the outside of the screening box 2, the output shafts of the two second motors 15 are respectively installed on the side ends of the two sealing plates 19, and two induction switches 14 for controlling the two second motors 15 are also installed on the side of the screening box 2;

[0045] Furthermore, when the material accumulation on the first mesh plate 21 reaches the maximum, the induction switch 14 controls the second motor 15 to drive the two sealing plates 19 to rotate to seal the space between the crushing box 1 and the screening box 2 .

[0046] The working principle of the present invention is as follows: first, the first motor is started to drive the crushing roller to rotate, and then the material is put into the crushing box 1, and the crushing roller can crush the ginkgo material, and the crushed material will pass through the first mesh plate 21 and fall into the two first collecting boxes 4, while the large pieces of material will be intercepted on the first mesh plate 21, completing the crushing and screening collection of the ginkgo material;

[0047] When the first mesh plate 21 is blocked and material cannot be discharged further, the material on the first mesh plate 21 will accumulate, causing the first mesh plate 21 to move downward under the action of gravity. The first mesh plate 21 moves downward, driving the connecting components thereon to move downward together. The connecting column 42 moves downward, driving the cross plate 30 to move downward. The cross plate 30 moves downward, driving the tooth plate 40 to move downward. The tooth plate 40 moves downward, driving the convex tooth 41 to move downward (at this time, the convex tooth 41 is engaged with the second gear 38, causing the second gear 38 to rotate). The convex tooth 41 moves downward, driving the second gear 38 to rotate and causing the second torsion spring 39 to generate a torsion force (the second torsion spring 39 can be selected to generate a torsion force). The torque is large enough to drive the subsequent components to work). Due to the setting of the one-way bearing 37, the third rotating rod 36 will not rotate at this time. When the tooth plate 40 moves downward to the maximum stroke (the material accumulation on the first mesh plate 21 reaches the maximum, the induction switch 14 controls the second motor 15 to drive the two sealing plates 19 to rotate to block the crushing box 1 and the screening box 2), the convex tooth 41 and the second gear 38 are separated, and the torque generated by the second torsion spring 39 will cause the second gear 38 to rotate in the opposite direction. The reverse rotation of the second gear 38 can drive the rotating rod to rotate through the one-way bearing 37, and the rotation of the rotating rod drives the first bevel gear 13 and the second bevel gear 34 to rotate;

[0048] The first bevel gear 13 rotates to drive the first rotating rod 12 to rotate, the first rotating rod 12 rotates to drive the second pulley 10 and the second belt 11 to rotate, the second pulley 10 rotates to drive the first gear 9 to rotate, the first gear 9 rotates to drive the first pulley 8, the first belt 7 and the two adjustment plates 18 to rotate, the two adjustment plates 18 rotate to make the large pieces of materials fall from the middle to the inside of the second collecting box 5, and the rotation of the two strip plates also drives the T-shaped shaft 16 to rotate and causes the first torsion spring 17 to generate torque;

[0049] The rotation of the second bevel gear 34 drives the second rotating rod 33 to rotate, the rotation of the second rotating rod 33 drives the rotating disk 31 to rotate, the rotation of the rotating disk 31 drives the movable rod 32 to move, the movement of the movable rod 32 drives the slider 29 to move, the movement of the slider 29 drives the connecting plate 27 and the second mesh plate 22 to move, so that the second mesh plate 22 no longer blocks the filter holes on the first mesh plate 21, so that the filter holes on the first mesh plate 21 become larger, and then large pieces of material can pass through the first mesh plate 21. In addition, the movement of the second mesh plate 22 will also drive the iron block 26 to move, and the movement of the iron block 26 will contact the electromagnet 43 and trigger the touch switch and the timing switch. At step 6, the electromagnet 43 will generate a sufficiently large suction force on the iron block 26, so that when a large piece of material is dropped, the second mesh plate 22 and the adjustment plate 18 will not move, thereby completing the cleaning of the material blocked on the first mesh plate 21 (during this period, as the material on the first mesh plate 21 decreases, the elastic force generated by the spring rod 23 will reset the material discharge frame 20, the first mesh plate 21, the connecting column 42, the cross plate 30, the tooth plate 40 and the convex tooth 41. Since the convex tooth 41 and the tooth plate 40 are connected by an elastic hinge, the tooth plate 40 and the convex tooth 41 will not drive the second gear 38 to rotate when they move upward);

[0050] When a certain period of time has passed, the timing switch 6 controls the touch switch to stop supplying power to the electromagnet 43, and the iron block 26 is no longer subjected to the magnetic force of the electromagnet 43. At this time, the torque generated by the two first torsion springs 17 will cause the adjustment plate 18 to rotate and reset. In summary, the rotation of the adjustment plate 18 can drive the second mesh plate 22 to move and reset (restore to the initial position) through the control mechanism, and the ginkgo material can be crushed and screened continuously and stably by reciprocating in sequence, thereby improving the use effect of the equipment.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
