Description

Movable sand blowing machine Technical Field The utility model relates to the technical field of sand blowers, in particular to a movable sand blower. Background The sand blasting machine is a mechanical equipment capable of spraying abrasive materials (metal abrasive materials and nonmetal abrasive materials) on the surface of a workpiece by means of compressed air power, and is characterized in that the compressed air is utilized in a pipeline to convey powdery particle materials from one place to another place, and in the process of converting kinetic energy into potential energy, sand grains moving at high speed are made to wash the surface of the object, so that the effect of improving the surface quality of the object is achieved. The existing movable sand blowing machine has the defects when in use, sand particles are often poured into a tank directly and then flow to a sand outlet in the sand conveying process of the sand blowing machine, blockage is easy to occur at the sand outlet, a sand blasting pipe and other parts, sand blasting operation is interrupted, uniform flow of sand is difficult to be carried out on the sand, the working efficiency of the sand blowing machine is reduced, and the movable sand blowing machine is improved and upgraded according to the problems. Disclosure of utility model The utility model aims to provide a movable sand blowing machine so as to solve the problems in the prior art. In order to solve the problems, the technical scheme is that the movable sand blowing machine comprises a sand storage tank, a conical hopper is fixedly arranged at the bottom of the sand storage tank, a sand outlet pipe is fixedly arranged at the bottom of the conical hopper, one end of the sand outlet pipe is fixedly connected with a sand blasting gun, three supporting legs are fixedly arranged on the outer wall of the sand storage tank, lifting structures are arranged inside the supporting legs, a movable wheel is rotatably arranged on the outer wall of each supporting leg, universal wheels are connected to the outer wall of the other supporting leg in a rolling mode, an adjusting structure is arranged inside the sand storage tank, the adjusting structure comprises a protection frame fixedly arranged inside the sand storage tank, a stirring motor is fixedly arranged inside the protection frame, a stirring shaft is fixedly connected to the output end of the stirring motor, and spiral guide vanes are fixedly connected to the outer wall of the stirring shaft.
