A movable baffle 14 is provided on the inner side of the screening chamber 3, a conveyor belt 15 is provided below the screening chamber 3, and a collection box 16 is provided below the discharge chamber 13. By controlling the rotation of the turntable 8, the connecting rod 7 drives the screening chamber 3 to sway left and right, so that the raw material is screened by the screen 4 to remove larger impurities. The blower 12 works to make the airflow carry the smaller impurities and dust in the raw material through the filter plate 5 into the dust collection hopper 9, and into the filter box 11 inside the dust collection chamber 10, so as to achieve full removal of impurities from the raw material. The removed raw material falls from the lower end of the screening chamber 3 onto the surface of the conveyor belt 15 for automatic feeding. During the screening process, the movable baffle 14 blocks the through groove to prevent the raw material from being discharged into the discharge chamber 13 along with impurities, thus avoiding unnecessary waste.

[0025] Please see Figures 1-4 In this embodiment, the upper end of the feed hopper 2 is provided with a cover, the lower end of the feed hopper 2 is connected to the inner side of the housing 1, the screening chamber 3 is adapted to the lower end of the feed hopper 2, the screen 4 is fixedly connected to the inner side of the screening chamber 3, the rollers 6 are arranged symmetrically front and back, and support plates 61 are fixedly installed on the front and back sides of the inner side of the housing 1. The upper ends of the rollers 6 and support plates 61 are adapted to each other, the left end of the connecting rod 7 is rotatably connected to the screening chamber 3 through a hinge seat, the right end of the connecting rod 7 is rotatably connected to the surface of the turntable 8, and the rear side of the turntable 8 is provided with There is a second support plate 81. The lower end of the second support plate 81 is fixedly connected to the inner side of the box 1 through a third support plate. A motor 82 is fixedly installed on the rear side of the second support plate 81. The output end of the motor 82 extends to the front side of the second support plate 81 and is fixedly connected to the turntable 8. The raw material to be screened is put into the screening chamber 3 inside the box 1 from the feed hopper 2. The turntable 8 is controlled to rotate by the motor 82, so that the connecting rod 7 drives the screening chamber 3 to sway left and right. The roller 6 rolls on the first support plate 61, so that the raw material is screened by the screen 4 to remove larger impurities.

[0026] Please see Figures 1-2In this embodiment, the rear end of the dust collection hopper 9 is connected to the inner side of the housing 1, and the front end of the dust collection hopper 9 is connected to the dust collection chamber 10 through a pipe. The filter box 11 and the inner side of the dust collection chamber 10 are slidably sleeved. A pull cover is provided on the right side of the filter box 11 extending to the outer side of the dust collection chamber 10. Ventilation holes are provided at both the front and rear ends of the filter box 11. A filter screen 111 is fixedly installed on the inner side of the filter box 111. A filter cotton 112 is provided on the rear side of the filter screen 111. The operation of the fan 12 causes the airflow to carry smaller impurities and dust in the raw materials through the filter plate 5 into the dust collection hopper 9 and into the filter box 11 inside the dust collection chamber 10. The airflow is filtered by the filter screen 111 and the filter cotton 112 to collect the impurities in the filter box 11, which facilitates subsequent centralized material discharge.

[0027] Please see Figures 2-5 In this embodiment, a through groove is provided on the right side of the screening chamber 3, located on the side of the screen 4. The discharge chamber 13 and the screening chamber 3 are connected to each other through the through groove. The movable baffle 14 is adapted to the right side of the through groove. An electric push rod 141 is fixedly installed on the right side of the discharge chamber 13. The output end of the electric push rod 141 extends to the inner side of the discharge chamber 13 and is fixedly connected to the movable baffle 14. The conveyor belt 15 is adapted to the lower end of the screening chamber 3. The right side of the conveyor belt 15 extends to the outer side of the box 1 through the discharge port. The collection box 16 is adapted to the lower end of the discharge chamber 13. The inner side of the 6 and the box 1 are slidably connected. The front end of the collection box 16 extends to the outer side of the box 1 and is provided with a handle. The raw material after screening and impurity removal falls from the lower end of the screening chamber 3 onto the surface of the conveyor belt 15 for automatic feeding. During the screening process, the moving baffle 14 blocks the through channel to prevent the raw material from being discharged into the discharge chamber 13 along with impurities, thus avoiding unnecessary waste. After the raw material is fed, the moving baffle 14 is driven by the electric push rod 141 to release the blockage of the through channel, so that the impurities screened out from the upper end of the screen 4 fall from the discharge chamber 13 into the collection box 16. The collection box 16 can be removed and cleaned later.

[0028] During operation, the raw material to be screened is fed from the feed hopper 2 into the screening chamber 3 inside the housing 1. The turntable 8 is rotated by the motor 82, causing the connecting rod 7 to drive the screening chamber 3 to sway left and right. The rollers 6 roll on the support plate 61, allowing the raw material to be screened by the screen 4 to remove larger impurities. At the same time, the blower 12 operates to drive the airflow to carry smaller impurities and dust in the raw material through the filter plate 5 into the dust collection hopper 9, and into the filter box 11 inside the dust collection chamber 10. The airflow passes through the filter screen 111 and the filter cotton 112. The filter collects impurities in the filter box 11 for easy centralized feeding later. After screening and impurity removal, the raw material falls from the lower end of the screening chamber 3 onto the surface of the conveyor belt 15 for automatic feeding. During the screening process, the moving baffle 14 blocks the through channel to prevent the raw material from being discharged into the discharge chamber 13 along with the impurities, thus avoiding unnecessary waste. After the raw material is fed, the moving baffle 14 is released from the through channel by the electric push rod 141, so that the impurities screened out from the upper end of the screen 4 fall from the discharge chamber 13 into the collection box 16. The collection box 16 can be removed and cleaned later.

[0029] Through the above steps, the rotation of the turntable 8 causes the connecting rod 7 to move the screening chamber 3 left and right, allowing the raw material to be screened by the screen 4 to remove larger impurities. The operation of the blower 12 causes the airflow to carry smaller impurities and dust in the raw material through the filter plate 5 into the dust collection hopper 9, and into the filter box 11 inside the dust collection chamber 10. During the screening process, the moving baffle 14 blocks the through channel to prevent the raw material from being discharged into the discharge chamber 13 along with impurities, thus avoiding unnecessary waste. This achieves thorough removal of impurities from the raw material, solving the problem that the raw material screening equipment only removes larger particles of impurities, leaving small debris and dust in the screened raw material, resulting in poor screening effect. Furthermore, the raw material is easily discharged along with impurities during the screening process due to excessive flow, leading to unnecessary waste.
