The corrugated pipe type guide pipe 4 can smoothly change the bending direction, the outlet of the guide pipe 4 in the shot blasting chamber 11 is changed, the steel shots 9 are electrified to be subjected to electrostatic repulsion of the inner wall of the guide pipe 4, the steel shots 9 only advance along the area near the central line of the guide pipe 4, the direction of the steel shots 9 is changed through repulsive force, the steel shots 9 do not touch the inner wall of the guide pipe 4, mechanical friction loss kinetic energy does not exist, the kinetic energy reduced by repulsive force in the process of entering the guide pipe 4 is released when leaving the guide pipe 4, and no absolute loss exists.
The deburring device further comprises a conveying belt 3, the conveying belt 3 is of a silk screen hollow structure, and the conveying belt 3 penetrates into and penetrates out of the side wall of the shell 1.
As shown in fig. 1, the conveyor belt 3 is used for placing workpieces, and since the guide pipe 4 can flexibly change the shot blasting direction, the placement of the workpieces can be relatively random, and the workpieces can be placed directly by using a conveyor belt with continuous feeding and discharging, the workpiece is manually placed on the conveyor belt 3 at the feeding end, and the workpiece with the deburring device is taken down at the discharging end.
The deburring device further comprises a dust remover 8, and the dust remover 8 is arranged at the air outlet of the shot blasting chamber 11. Dust fine particles on the surface of a workpiece in the deburring process are also removed, ascending air flow at the separation assembly 6 and carrier gas of shot blasting are discharged from the shot blasting chamber 11, the discharged air has high dust content, dust is collected by the dust collector 8 to prevent the surrounding operation environment from being bad, and the health of operators is ensured.
