Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, and in particular to a mobile sandblasting machine. Background Technology

[0002] A sandblasting machine is a mechanical device that uses compressed air to propel abrasive materials (metallic and non-metallic) onto the surface of a workpiece. It works by using compressed air to transport powdery granular materials from one place to another within a pipeline. During the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, thereby improving the surface quality of the object.

[0003] Existing mobile sand blowing machines have some shortcomings in use. Often, during the sand conveying process, sand particles are directly poured into the tank and then flow to the sand outlet, which can easily cause blockages at the sand outlet, sandblasting pipe, and other parts, leading to interruptions in sandblasting operations, difficulty in uniformly flowing sand, and reduced working efficiency of the sand blowing machine. To address these issues, a mobile sand blowing machine has been proposed for improvement and upgrading. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device is equipped with an adjustment structure.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, this embodiment provides a mobile sand blowing machine, including a sand storage tank 1. A conical bucket 2 is fixedly installed at the bottom of the sand storage tank 1. A sand discharge pipe is fixedly installed at the bottom of the conical bucket 2, and a sand blasting gun 7 is fixedly connected to one end of the sand discharge pipe. Three support legs 3 are fixedly installed on the outer wall of the sand storage tank 1, and each support leg 3 is provided with a lifting structure 6. Two of the support legs 3 are rotatably installed with moving wheels 5 on their outer walls, and the other support leg 3 is rolledly connected with a universal wheel 51 on its outer wall. An adjustment structure 11 is provided inside the sand storage tank 1. The adjustment structure 11 includes a protective frame 111 fixedly installed inside the sand storage tank 1. A stirring motor 112 is fixedly installed inside the protective frame 111. A stirring shaft 113 is fixedly connected to the output end of the stirring motor 112, and a spiral guide vane 115 is fixedly connected to the outer wall of the stirring shaft 113.

[0024] like Figures 3 to 4 As shown, the spiral guide vane 115 is rotatably installed inside the sand outlet pipe, and one end of the spiral guide vane 115 penetrates the conical bucket 2. The outer wall of the sand outlet pipe is fixedly equipped with a regulating valve 8. The outer wall of the stirring shaft 113 is fixedly equipped with two fixing sleeves 116. The outer walls of the two fixing sleeves 116 are each fixedly equipped with three stirring supports 114, and the outer walls of the three stirring supports 114 are in contact with the inner wall of the conical bucket 2 and rotate. The outer wall of the sand storage tank 1 is fixedly equipped with an air inlet pipe 9 and a pressure relief valve 10, respectively. One of the support legs 3 is fixedly equipped with a pressure sensor 4 on its outer wall.

[0025] The stirring motor 112 drives the three stirring supports 114 on the stirring shaft 113 to rotate, which causes the sand in the conical bucket 2 to be stirred and dispersed, and the sand adhering to the inner wall of the conical bucket 2 to be scraped off for easy cleaning. At the same time, the spiral guide vanes 115 rotate and spray the sand evenly from the sandblasting gun 7. The pressure sensor 4 collects data in real time during the operation of the equipment and transmits the data to the control system. The control system controls the actuators such as the regulating valve 8 and the variable frequency air compressor according to the preset parameters and algorithms, so as to realize the automated operation of the equipment and the precise adjustment of parameters. The existing technology is mature and can achieve this.

[0026] like Figure 5 As shown, the lifting structure 6 includes a lifting cylinder 61 fixedly installed inside the support leg 3. One end of the lifting cylinder 61 is fixedly connected to a guide column 62, and the other end of the guide column 62 is fixedly connected to an anti-slip pad 64. Two limiting grooves 65 are opened on the inner wall of the support leg 3. Two limiting blocks 63 are symmetrically fixedly connected to the outer wall of the guide column 62, and the limiting blocks 63 are slidably connected inside the limiting grooves 65. The guide column 62 is adapted to the support leg 3.

[0027] By adjusting the height of the sandblasting machine during operation, the movable wheels 5 and the universal wheels 51 can be raised to ensure that the equipment is stable and does not shift during operation, thus improving the working stability of the sandblasting machine. When it is necessary to move, the sandblasting machine can be lowered and moved conveniently using the movable wheels 5 and the universal wheels 51, making it easy to use.

[0028] The working principle and process of this utility model: When using the sandblasting machine, the operator first moves the equipment to the work site by using the universal wheels 51 and the movable wheels 5. Then, the operator starts the lifting cylinders 61 in the three support legs 3 through the touch screen. The three lifting cylinders 61 drive the guide column 62 to slide in the limit groove 65 using the limit block 63. This makes the anti-slip pad 64 on the guide column 62 contact the ground, thereby raising the equipment to a suitable height and adjusting it to a horizontal state. This makes it easier to move and transport the sandblasting machine while improving its working stability.

[0029] After the sandblasting machine height is adjusted, the sandblasting pressure and the speed parameters of the stirring motor 112 are preset on the display screen. The compressed air generated by the air compressor enters the sand storage tank 1 through the air inlet pipe 9, forming pressure inside the tank and forcing the sand out from the sand outlet. The regulating valve 8 is turned to open it. At this time, the stirring motor 112 inside the drive guard frame 111 works, causing the stirring motor 112 to drive the three stirring brackets 114 on the outside of the stirring shaft 113 to rotate along the inner wall of the conical bucket 2. This facilitates the stirring and dispersing of the sand on the conical bucket 2 while avoiding the sand adhering to the inner wall of the conical bucket 2 and causing problems such as difficulty in cleaning. At the same time, when the stirring shaft 113 rotates, it drives the spiral guide vanes 115 in the sand outlet pipe to rotate, and then guides the sand to flow evenly, reducing the sand accumulation on the pipe wall and causing blockage problems. The sand is then sprayed out from the sandblasting gun 7 under pressure along the outlet pipe to perform the spraying operation on the object.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
