[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The utility model starts the motor, and the motor drives the turbine blades to work through the driving rod. Under the action of the turbine blades, the dust in the air will enter the dust collection duct. Since a dust filter plate is provided in the dust collection duct, the dust will be filtered under the action of the dust filter plate, and the dust will remain on the surface of the dust filter plate, thereby cleaning the dust in the air. Compared with the existing ones, the utility model avoids the pollution of the environment by the dust by cleaning the dust in the air.

[0021] The utility model drives the threaded part to move in the threaded hole by rotating the turning bar. After the fixing plate at one end of the threaded part is no longer in contact with the connecting tube, the position of the connecting tube in the dust collection duct can be adjusted, thereby adjusting the height of the connecting tube and the tapered tube. After the position of the connecting tube is adjusted, the turning bar is rotated again to drive the threaded part to move in the threaded hole. After the fixing plate at one end of the threaded part is in contact with the connecting tube, the connecting tube and the tapered tube can be fixed. Therefore, the utility model can be applied to different scenarios and has high applicability.

[0022] The utility model takes the bayonet pin out of the bayonet slot and then rotates the turning bar, which drives the threaded member to move in the threaded hole. After the fixing plate at one end of the threaded member is no longer in contact with the connecting pipe, the connecting pipe and the conical pipe can be disassembled, and then the dust filter plate can be disassembled. Therefore, the utility model is convenient for collecting and cleaning the dust on the dust filter plate, thereby improving the utilization rate of the dust and the working efficiency of the dust filter plate.

[0038] First, by starting the motor 5, the motor 5 drives the turbine blades 7 to work through the driving rod 6. Under the action of the turbine blades 7, the dust in the air will enter the dust collection pipe 1. Since a dust filter plate 8 is provided inside the dust collection pipe 1, the dust will be filtered under the action of the dust filter plate 8, and the dust will remain on the surface of the dust filter plate 8, thereby cleaning the dust in the air. Compared with the existing ones, the utility model avoids the pollution of the environment by dust by collecting and cleaning the dust in the air, improves the processing environment, and helps to improve the work efficiency of workers.

[0039] Secondly, by rotating the turning bar 15, the turning bar 15 drives the threaded member 14 to move in the threaded hole 13. After the fixing plate 16 at one end of the threaded member 14 is no longer in contact with the connecting tube 3, the position of the connecting tube 3 in the dust collection duct 1 can be moved, thereby adjusting the height of the connecting tube 3 and the tapered tube 4. After the position of the connecting tube 3 is adjusted, the turning bar 15 is rotated again to drive the threaded member 14 to move in the threaded hole 13. After the fixing plate 16 at one end of the threaded member 14 is in contact with the connecting tube 3, the connecting tube 3 and the tapered tube 4 can be fixed. Therefore, the utility model can be applied to different scenarios and has high applicability.

[0040] Finally, by taking the latch pin 11 out of the slot 10 and then rotating the turn bar 15, the turn bar 15 drives the threaded member 14 to move in the threaded hole 13. After the fixing plate 16 at one end of the threaded member 14 is no longer in contact with the connecting pipe 3, the connecting pipe 3 and the conical tube 4 can be disassembled, and then the dust filter plate 8 can be disassembled. Therefore, the utility model is convenient for collecting and cleaning the dust on the dust filter plate 8, thereby improving the utilization rate of the dust and the working efficiency of the dust filter plate 8.
