[0002] Compared with dry sandblasting machines, the biggest feature of liquid sandblasting machines is that they can well control dust pollution during the sandblasting process and improve the working environment of sandblasting operations. When feeding the liquid sandblasting machine, the sand and solution are generally mixed in the liquid cylinder. After the sand is mixed, the workpiece is polished by a sandblasting polishing machine.

[0003] The existing application number is: CN201920965528.0. The utility model discloses a sand material distributor and a sandblasting machine, including a distribution tube and a plug. The lower end of the inner part of the distribution tube is horizontally provided with a screen plate, and the middle part of the lower surface of the screen plate is provided with a driving motor. The motor shaft output end of the driving motor is fixedly connected to the rotating rod. The outer wall of the rotating rod is respectively provided with a stirring blade and a blade, and the stirring blade is placed above the blade. A feed port is provided in the middle part of the upper surface of the distribution tube. The utility model controls the first electromagnetic valve to open, and water is introduced to mix with the sand material. The driving motor is controlled to work and can drive the stirring blade to rotate through the rotating rod to mix the water and the sand material. The agglomerated sand material can be filtered through the screen plate. When the driving motor drives the stirring blade to rotate, it can also drive the blade to rotate, and further crush and stir the agglomerated sand material, thereby improving the uniform mixing efficiency of water and sand material. The driving motor is controlled to work, and the precipitation of the sand material in the distribution tube can be avoided, thereby improving the use efficiency of the device.
