The center of the arc of the support plate 13 is located on the central axis of the cylindrical screen 12. The edge of the cylindrical screen 12 that slides in contact with the inner wall of the box door 3 slides against the support plate 13.

[0028] In this embodiment, the door 3 is detachably installed onto the dust collection box 1. The installation method includes, but is not limited to, existing methods such as bolt fixing.

[0029] A vacuum cleaner 4 is fixedly installed on the outer wall of the door 3. The suction port of the vacuum cleaner 4 is fixedly connected to a pipe 5, which is fixedly connected to the interior of the dust collection box 1. The connection between the pipe 5 and the dust collection box 1 is located below the cylindrical screen 12.

[0030] The bottom inner wall of the dust collector 1 is funnel-shaped, and the bottom of the dust collector 1 is fixed and connected to the dust discharge pipe 18.

[0031] A motor 6 is fixedly installed on the dust collection box 1, and the cylindrical screen 12 is driven by the output shaft of the motor 6 through a first transmission component.

[0032] Specifically, the first transmission assembly includes a swing plate 10 and a transmission shaft 9. A horizontal rotating shaft 7 is rotatably mounted on the outer wall of the dust collector 1 away from the door 3, and the rotating shaft 7 is coaxial with the cylindrical screen 12. The swing plate 10 is arranged radially along the rotating shaft 7 and is fixedly connected to the rotating shaft 7.

[0033] An arc-shaped connecting plate 11 is fixedly connected to the axial end of the cylindrical screen 12 away from the door 3, with the arc center of the connecting plate 11 located on the central axis of the cylindrical screen 12. The connecting plate 11 extends out of the dust collector 1 and is fixedly connected to the end of the swing plate 10 away from the rotating shaft 7. A clearance groove 16 is provided on the body of the dust collector 1 for the connecting plate 11 to move. The clearance groove 16 is an arc-shaped groove, and the axial end of the cylindrical screen 12 away from the door 3 slides to seal the clearance groove 16.

[0034] A transmission plate 8 is fixed radially on the output shaft of motor 6, and a transmission shaft 9 is fixed at the end of the transmission plate 8 away from the output shaft of motor 6. A transmission groove is formed radially on the swing plate 10 along the rotating shaft 7, and the transmission shaft 9, the rotating shaft 7, and the output shaft of motor 6 are parallel to each other. The transmission shaft 9 passes into the transmission groove and is limited and slidably engaged with the transmission groove, and the transmission shaft 9 abuts against the swing plate 10 for transmission engagement.

[0035] Two horizontally mounted agitator shafts 14 with stirring rods are placed inside the dust collector 1. The two shafts 14 are parallel to each other and both are parallel to the central axis of the cylindrical screen 12. Both shafts 14 are rotatably connected to the dust collector 1. One shaft 14 is connected to the output shaft of the motor 6 via a second transmission assembly. The two shafts 14 are also connected via a linkage assembly.

[0036] Specifically, both the second transmission assembly and the linkage assembly include a transmission belt 17 and two pulleys 15. Both stirring shafts 14 extend out of the dust collection box 1, with two pulleys 15 fixedly fitted on one stirring shaft 14, and one pulley 15 fixedly fitted on both the other stirring shaft 14 and the output shaft of the motor 6.

[0037] The pulley 15 on the output shaft of the motor 6 is connected to one of the pulleys on the stirring shaft 14, which is fitted with two pulleys 15, within one of the transmission belts 17.

[0038] Suppose that another pulley 15 on the stirring shaft 14 of the two pulleys 15 is connected to another pulley 15 on the stirring shaft 14 within another transmission belt 17.

[0039] Working principle: When using this dust removal device to separate down and dust, the raw feathers are added into the cylindrical screen 12 through the feed inlet 2 and the loading port. Then, the motor 6 and the vacuum cleaner 4 are started.

[0040] After motor 6 starts, its output shaft drives the corresponding pulley 15 to rotate. This pulley 15 is driven to rotate via a corresponding transmission belt 17. This pulley 15 drives the corresponding stirring shaft 14 to rotate, which in turn drives another pulley 15 to rotate. This pulley 15, via a corresponding transmission belt 17, drives another pulley 15 on the stirring shaft 14 to rotate, which in turn drives the stirring shaft 14 to rotate.

[0041] When the two stirring shafts 14 rotate, they drive the stirring rods to break up the raw material.

[0042] Meanwhile, the output shaft of motor 6 drives the transmission plate 8 to rotate, and the transmission plate 8 drives the transmission shaft 9 to revolve around the output shaft of motor 6. The transmission shaft 9 pushes the swing plate 10 to swing back and forth, and the swing plate 10 drives the connecting plate 11 to revolve around the rotating shaft 7 along the relief groove 16. The connecting plate 11 drives the cylindrical screen 12 to revolve around the rotating shaft 7.

[0043] As the cylindrical screen 12 rotates back and forth, dust and debris roll along the inner wall of the cylindrical screen 12 and fall through the screen holes. Part of the fallen dust and debris is sucked away by the vacuum cleaner 4 through the pipe 5, and the other part is discharged through the dust discharge pipe 18.

[0044] After dust removal is complete, turn off motor 6 and vacuum cleaner 4. Then, open door 3, remove the raw wool, and replace door 3.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
