Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, Figure 2 and Figure 3, this shot-blasting machine includes air pump, shell 1, driving motor 2, rotor 31 and shaft 3, is driven
The shell of dynamic motor 2 is fixed on shell 1, and the output shaft of driving motor 2 is connected with shaft 3, and rotor 31 is fixed in shaft 3,
Shaft 3 is rotatably connected on shell 1, is had tapping channel 11 and storage cavity 12 on shell 1, is circumferentially evenly arranged on rotor 31
If siccative thorax 32, material thorax 32 can be located in storage cavity 12, and material thorax 32 can be located along the same line with tapping channel 11, shell
There is a connector 4, the outlet side jointing 4 of air pump, material thorax 32 can be connected to connector 4 and tapping channel 11 on 1；Driving motor
