[0003] After searching, the utility model with the announcement number CN211728809U discloses a dust removal mechanism for a piston rod grinding device. Although the utility model patent solves the problem that the existing piston rod grinding device does not have the dust removal function, a large amount of dust will be generated when the piston rod is being ground. The workers inhale the dust for a long time, which is harmful to the workers' health and inconvenient for workers to use; however,

[0004] 1. The vacuum cleaner, installation mechanism, vacuum pipe and vacuum hood of the utility model patent are fixed in position, and cannot follow the movement of the tool to remove dust when the tool is grinding the piston rod. When the tool is far away from the vacuum cleaner, the vacuuming effect is insufficient, and workers are still at risk of inhaling dust, which is harmful to their health.

[0005] Second, the utility model is provided with a water exchange pipe, a water exchange valve, a water tank and a filter mechanism. Since the piston rod has been roughly processed before grinding, the dust generated by grinding is less. It is costly to set a filter mechanism for each grinding device, and the filter mechanism of the utility model is large in size, which is not conducive to the transportation of the piston rod grinding device;

[0006] Therefore, a dust removal mechanism for a piston rod grinding device is proposed. Utility Model Content

[0027] In one embodiment, an I-shaped connector 23 is fixedly connected to the top of the dust collecting outer box 11, a threaded rod 19 is rotatably connected to the outer wall of the I-shaped connector 23, a connecting block 24 is threadedly connected to the outer wall of the threaded rod 19, the connecting block 24 is fixedly connected to the reciprocating outer shell 5, and a handle 20 is fixedly connected to the top of the threaded rod 19.

[0028] In one embodiment, a handle 21 is fixedly connected to the outer wall of the dust collecting inner box 13, and the handle 21 is located at an end away from the grinding tool 2. The reciprocating screw 4 is parallel to the limit rod 8. This ensures that the reciprocating outer shell 5 can slide smoothly.

When the dust suction port 12 is far away from the piston rod body 22 and the dust suction effect is insufficient, the staff turns the handle 20, and the rotation of the handle 20 drives the threaded rod 19 to rotate. With the cooperation of the telescopic rod 10, the dust collecting outer box 11 rises, thereby shortening the distance between the grinding tool 2 and the dust suction port 12, and the dust suction effect is better. When the piston rod body 22 is large, the handle 20 can be reversed to give the piston rod body 22 enough space.
