The discharge pipe 9 on the material distribution tank 20 extends toward the hollow area, so that the material can be sprayed directly on the wall.

[0063] See also Figure 2 As shown, the inner wall of the discharge pipe 9 is provided with a thread, and the nozzle 10 has an external thread. The nozzle 10 can be threadedly connected to the discharge pipe 9. A feed hole is provided on the side wall of the storage tank 7. A feed pipe is sleeved inside the feed hole.

[0064] In one possible embodiment, see Figure 1 , Figure 3 , Figure 4 and Figure 8As shown, the bracket includes four metal plates 27, four channel steels 29, two connecting rods 28, two fixing columns 13 and a fixing frame 8. The four metal plates 27 are fixed to the back plate 1 by fasteners. For example, each metal plate 27 is arranged at the four corners of a rectangle, and the four channel steels 29 are welded to the corresponding metal plates 27, and the channel steels 29 and the metal plates 27 are perpendicular to each other. The two connecting rods 28 are respectively connected to the two channel steels 29 arranged in sequence in the direction perpendicular to the guide rack 3, and the two fixing columns 13 are respectively connected to the two channel steels 29 arranged in sequence in the direction parallel to the guide rack 3.

[0065] Two clamps 21 are arranged on the fixing frame 8. The material distribution tanks are respectively penetrated by the two clamps 21, and the two clamps 21 have a good fixing effect on the material distribution tanks. A circular hole for the discharge pipe 9 to pass through is opened on the surface of the fixing frame 8, and a buffer pad is arranged between the inner circle of the circular hole and the outer surface of the discharge pipe 9.

[0066] The working principle of the sandblasting device of the present invention is briefly described below:

[0067] In the preliminary work, the guide rack 3 is connected to the wall surface by fixing bolts 11, and the spacing between each guide rack 3 is designed. The interior of the storage tank 7 is filled with mortar, and then the drive motor 5 and the air pump 6 are started by the mobile terminal control. After the drive motor 5 is started, the drive motor 5 drives the input shaft 24, and drives the first bevel gear 25 to rotate through the input shaft 24, and drives the two second bevel gears 23 to rotate. The rotation of the two second bevel gears 23 drives the two output shafts 26 to rotate respectively, and the rotation of the two output shafts 26 drives the two gears 15 to rotate. The two gears 15 rotate and climb along the guide rack 3, driving the entire back panel 1 and the spray assembly to rise and fall. The matching relationship between the gear 15 and the guide rack 3 is conducive to the stable climbing of the back panel 1 and the spray assembly along the guide rack 3.

[0068] After the air pump 6 is started, the pressurized gas inside the air pump 6 will be injected into the storage tank 7 through the air pipe 16, and the mortar inside the storage tank 7 will be squeezed into the hose 18 by the squeezed gas, and then injected into the distribution tank 20 through the hose 18. The auger 19 inside the distribution tank 20 will rotate due to the impact of the pressurized gas and mortar, and stir and transport the mortar through its own rotation. At the same time, the pressurized gas uses the impact force to transport the mortar along the discharge pipe 9 to the inside of the nozzle 10. Under the guidance of the nozzle 10, the mortar is sprayed onto the wall. At the same time, the whole device is climbing at a uniform speed, so that the mortar can be evenly sprayed onto the wall. There is no need to manually sandblast the wall. After the mortar inside the storage tank 7 is sprayed, the drive motor 5 is controlled to stop running, while the air pump 6 continues to operate, and the gas continued to be sprayed by the air pump 6 is used to remove the residual mortar inside the discharge pipe 9 and the nozzle 10 to prevent the mortar inside the discharge pipe 9 and the nozzle 10 from hardening and causing blockage.

[0069] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
