[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, when in use, first connect one end of the main air pipe to the air compressor. After the high-pressure gas enters the main air pipe, open the first valve, the high-pressure gas will enter the air pipe, and with the cooperation of the first three-way joint, part of the gas will enter the sandblasting pot. At this time, the internal pressure of the sandblasting pot increases. After opening the second valve, the quicksand in the sandblasting pot will flow downward along the straight pipe. When the gas in the air pipe passes through the second three-way valve, a negative pressure area will be formed at the straight pipe. The speed of the quicksand is increased by means of negative pressure, and the quicksand is taken away and transported to the sandblasting nozzle through the sandblasting pipe, and the gear is sandblasted and polished. Since the sandblasting is carried out in the sandblasting shell, the sandblasting overflow can be reduced, the dust can be prevented from spreading, and the cleanliness of the work site can be ensured.

[0015] 2. In the utility model, when the gear is sandblasted, the rotating motor drives the gear to rotate through the stud, thereby realizing all-round sandblasting and grinding of the gear; the sandblasting efficiency of the gear is greatly improved, and the uniform sandblasting effect is good.

[0016] 3. In the utility model, the flowing sand after the gear grinding enters the sand box through the sand outlet and is collected, thereby realizing the collection of sand and gravel, which is convenient for subsequent recycling. BRIEF DESCRIPTION OF THE DRAWINGS
