Two moving rods 16 are fixedly installed on the outer wall of the connecting plate 15. One end of the moving rod 16 enters the housing 1 and is fixedly installed with an operating plate 21. A plurality of evenly distributed storage frames 24 are fixedly installed on the top of the operating plate 21. The top of the storage frames 24 has slots. 26. A limiting groove 27 is provided on the inner wall of the slot 26. A through opening 28 is provided on the top surface of the limiting groove 27. A second spring 29 is fixedly installed on the inner wall of the limiting groove 27. A locking block 30 is fixedly installed on one end of the second spring 29. A pull plate 31 is fixedly installed on the top of the locking block 30. An insert plate 33 is slidably installed inside the slot 26. A locking groove 25 is provided on the outer wall of the insert plate 33. A rubber ball 32 is fixedly installed on the top of the insert plate 33. Two screening frames 17 are provided inside the box body 1. Multiple evenly distributed through holes 37 are provided on the bottom surface of the screening frame 17.

[0024] The overall effect of Embodiment 1 is that when the screening frame 17 shakes up and down, the bottom of the screening frame 17 continuously contacts the rubber ball 32. The rubber ball 32 impacts the bottom of the screening frame 17, causing the particles blocking the through hole 37 to leave the through hole 37. At the same time, the operator starts the electric telescopic rod 14. The telescopic end of the electric telescopic rod 14 drives the connecting plate 15 to move, and then drives the operating plate 21 to move back and forth through the moving rod 16, which increases the impact range, further improves the screening efficiency, and facilitates cleaning.

[0025] Example 2, as Figures 1-5 As shown, further, lifting plates 5 are slidably installed on both sides of the outer side of the box body 1. A control plate 6 is fixedly installed on the outer wall of one of the two lifting plates 5, and a moving plate 10 is fixedly installed on the outer wall of the other lifting plate 5. A U-shaped plate 7 is fixedly installed on the outer side of the box body 1 near the control plate 6. A motor 8 is fixedly installed on the outer wall of the U-shaped plate 7. The output end of the motor 8 passes through the U-shaped plate 7 and is fixedly installed with a cam 9.

[0026] Furthermore, a U-shaped frame 11 is fixedly installed on the outside of the box 1 near the movable plate 10. Multiple first springs 12 are fixedly installed between the U-shaped frame 11 and the movable plate 10. Two placement frames 18 are provided inside the box 1. Openings 19 are provided through both sides of the inside of the box 1. Support plates 20 are fixedly installed on both sides of the outside of the placement frames 18. One end of the two support plates 20 is fixedly connected to the lifting plate 5.

[0027] Furthermore, two connecting slots 34 are provided at the top of the placement frame 18, and an electromagnet 35 is fixedly installed on the inner wall of the connecting slot 34.

[0028] Furthermore, two iron plates 36 are symmetrically installed at the bottom of the screening frame 17. When placing the frame, the operator inserts the iron plates 36 into the connecting groove 34 and activates the electromagnet 35. The iron plates 36 are attracted to the outer wall of the electromagnet 35, thus fixing the screening frame 17.

[0029] Furthermore, a door 2 is hinged to the outer wall of the box 1, and a triangular plate 23 is fixedly installed on the top of the operating plate 21 to prevent particles from falling onto the operating plate 21.

[0030] Furthermore, a feed inlet 3 is provided through the top of the box 1, a collection box 4 is provided on the bottom surface inside the box 1, and a funnel 22 is fixedly installed on the inner wall of the box 1.

[0031] The effect achieved by the entire embodiment 2 is as follows: When in use, the staff pours the raw material into the box 1 from the feed port 3, and then the raw material falls into the screening frame 17. The staff starts the motor 8, and the output end of the motor 8 drives the cam 9 to rotate, so that the cam 9 contacts the control plate 6, causing the control plate 6 to rise. In turn, the support plate 20 drives the screening frame 17 to rise, and the first spring 12 is stretched. When the cam 9 is no longer in contact with the control plate 6, the elastic force of the first spring 12 drives the screening frame 17 to fall. At this time, the screening frame 17 shakes up and down, which improves the screening efficiency.

[0032] Working principle: During use, the operator pours the raw material into the box 1 through the feed port 3, and then the raw material falls into the screening frame 17. The operator starts the motor 8, and the output end of the motor 8 drives the cam 9 to rotate, so that the cam 9 contacts the control plate 6, causing the control plate 6 to rise. In turn, the support plate 20 drives the screening frame 17 to rise, and the first spring 12 is stretched. When the cam 9 is no longer in contact with the control plate 6, the elastic force of the first spring 12 drives the screening frame 17 to fall. At this time, the screening frame 17 shakes up and down, which improves the screening efficiency. When the screening frame 17 shakes up and down, the bottom of the screening frame 17 continuously contacts the rubber ball 32. The rubber ball 32 impacts the bottom of the screening frame 17, causing the particles blocking the through hole 37 to leave the through hole 37. At the same time, the operator starts the electric telescopic rod 14. The telescopic end of the electric telescopic rod 14 drives the connecting plate 15 to move, which in turn drives the operating plate 21 to move back and forth through the moving rod 16, increasing the impact range and further improving the screening efficiency and facilitating cleaning. When the rubber ball 32 is damaged, the operator pulls the pull plate 31, and the locking block 30 leaves the slot 25. At this time, the operator can pull out the insert plate 33 and replace it with a new insert plate 33. Insert the insert plate 33 into the slot 26. The insert plate 33 contacts the inclined surface of the locking block 30, and the locking block 30 enters the limiting groove 27. The second spring 29 is compressed. When the slot 25 moves next to the locking block 30, the elastic force of the second spring 29 pushes the locking block 30 into the slot 25, thus completing the replacement. When the screening is finished, the staff can open the box door 2 and take out the collection box 4 and the screening frame 17 for collection.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
