[0034] The air with dust in the shot blasting machine enters the dust collecting tube 1 through the air inlet pipe 11, and then passes through the filter medium 6 upwards. The filter medium 6 filters the dust in the air to the bottom of the filter medium 6. The clean air enters the exhaust chamber 2 and is then transported to the fan through the air outlet pipe 3. The fan provides power for the flow of air. The rotating shaft 5 can drive the scraper 51 to scrape the dust at the bottom of the filter medium 6 through its own rotation. Then, under the action of the guide plate 53, the dust enters between the scraper 51 and the collecting plate 52, and then enters downward into the vertical pipe 4. Due to the setting of the vertical pipe 4, the disturbance of the air flowing outside the vertical pipe 4 to the dust can be blocked, so that the dust can fall to the bottom of the dust collecting tube 1 more smoothly; through the setting of the guide plate 53, the dust scraped by the scraper 51 can be bound to a certain extent, so that even if the dust is disturbed by the air, it can enter between the scraper 51 and the guide plate 53 more smoothly, so that it can enter the vertical pipe 4 more smoothly.

[0039] The air sent into the dust collector 1 by the air inlet pipe 11 will directly hit the side plate along the tangent direction of the dust collector 1, and part of the air will flow downward in a spiral under the restraint of the guide plate 7, so that the dust in the air will lose power due to the collision with the guide plate 7, so that part of the dust can fall to the bottom of the dust collector 1.

[0040] Specifically, the guide plate 7 is arranged in a circle around the axis of the dust removal cylinder 1 ; the connection between the air inlet pipe 11 and the dust removal cylinder 1 is located at the bottom of one end of the top of the guide plate 7 .

[0041] Specifically, a plurality of vertically arranged support rods 15 are fixedly connected to the bottom of the collecting bucket 12 ; a plurality of connecting rods fixedly connected to the inner wall of the dust removal cylinder 1 are fixedly connected to the outside of the vertical pipe 4 .
