[0002] The mobile sandblasting machine with adjustable flow is an auxiliary device for sandblasting the surface of a casting blank; the existing flow regulating structure is used in the case of sand particles, and the sand particles are very small and easily penetrate into the gaps, resulting in poor movement of the structure and finally getting stuck.

[0003] Based on this, the applicant proposed a sand flow and flow rate control structure with application number 202320928738.9 on April 23, 2023. The structure adjusts the amount of sand output by controlling the closing of the hose and the size of the opening of the hose. The control structure does not contact the sand particles, but only contacts the hose that controls the sand particles. This avoids the phenomenon in which the sand particles in the original structure drill into the gaps and cause the mechanism to get stuck. It ensures that the sand particles are only delivered to the mechanisms and occasions where they need to work, avoiding the phenomenon of sand particles flowing everywhere and getting stuck in the mechanism.
