[0012] Preferably, the diameter of the circular groove formed on the outer wall of the adjusting plate is the same as the diameter of the circular groove formed on the outer wall of the clamping plate.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] During use of the utility model, when it is necessary to use high-speed sprayed microparticles to process an object, first, air is allowed to enter the interior of the venturi tube under the action of an external air pump.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] like Figure 1-Figure 6 As shown, the utility model provides a nozzle for a particle shot blasting machine, including a venturi tube 1, the outer wall of the venturi tube 1 is fixedly connected to a delivery pipe 3, the outer wall of the delivery pipe 3 is movably sleeved with an adjusting column 4, the inner wall of the adjusting column 4 is provided with two clamping plates 5, an adjusting plate 6 is provided between the outer walls of the two clamping plates 5, a plurality of circular grooves 7 are provided on the adjusting plate 6 and the clamping plates 5, a feeding pipe 8 is provided on the inner wall of the adjusting column 4, and the feeding pipe 8 and the outer wall of the delivery pipe 3 are both provided with sealing rings 9.

[0027] When the outer surface of the object needs to be processed, the equipment is first started to allow the external air to pass through the Venturi tube 1 quickly, and at the same time, the microparticles are sent into the feed pipe 8. Then the staff manually rotates the adjustment plate 6 to keep the circular groove 7 opened on the outer wall of the adjustment plate 6 and the clamping plate 5 connected and maintained at a suitable size, so that the microparticles can smoothly enter the Venturi tube 1. At the same time, under the action of the sealing ring 9, the conveying pipe 3, the adjustment column 4 and the feed pipe 8 can maintain good air tightness to avoid leakage of microparticles and cause waste. After the microparticles enter the Venturi tube 1, the air will carry the microparticles and spray them onto the surface of the object to be processed while passing through the Venturi tube 1 quickly, thereby completing the processing of the surface of the object. The above method can be used to adjust the input amount of the microparticles, thereby improving the processing effect on the object.

[0028] like Figure 2-Figure 6As shown, a universal curved tube 2 is movably sleeved on the venturi tube 1, and the inner surface wall of the universal curved tube 2 is connected to the outer surface wall of the venturi tube 1 by threads, and a fixing frame 10 is fixedly sleeved on the end of the venturi tube 1, and an annular groove 11 is opened on the fixing frame 10, and an air pipe 12 is movably inserted into the inner surface wall of the annular groove 11, and four limiting grooves 13 are opened on the outer surface wall of the air pipe 12, and four installation boxes 14 are fixedly installed on the outer wall of the fixing frame 10, and the inner surface walls of the four installation boxes 14 are all movably embedded with limiting blocks 15, and the outer surface walls of the limiting blocks 15 are movably inserted in the limiting grooves 13, and the inner surface walls of the four installation boxes 14 are all provided with limiting springs 16, and the ends of the limiting springs 16 are fixedly connected to the limiting blocks 15, and the circular grooves 7 opened on the outer walls of the adjusting plate 6 and the clamping plate 5 have the same diameter.

[0029] When using microparticles to process the surface of an object, first, under the action of the universal curved tube 2, the angle of the sprayed microparticles can be adjusted, thereby improving the effect of processing the surface of the object. When the nozzle needs to be maintained, first, under the manual operation of the staff, the limit block 15 is pressed to move inside the installation box 14 to compress the limit spring 16. Since one end of the limit spring 16 is fixedly connected to the limit block 15 and the other end is fixedly connected to one side of the inner wall of the installation box 14, the limit spring 16 can remain stable when moving inside the installation box 14, and then the limit block 15 is taken out from the limit groove 13, and finally the Venturi tube is removed from the gas pipe, which is more convenient for the staff to maintain and service it, and after completing the maintenance and service, the Venturi tube can be installed through the above-mentioned structure and method. This installation method greatly improves the efficiency of installation and disassembly, and further improves practicality.

[0030] Working principle: When it is necessary to use high-speed sprayed microparticles to process the surface of an object, first start the equipment to allow the external air to quickly pass through the Venturi tube 1 (it should be noted that the air delivery pipe in this embodiment is connected to the external equipment, relying on the relatively small inner diameter of the middle part of the Venturi tube to achieve the speed increase of air flow), and at the same time, send the microparticles into the feed pipe 8, and then manually rotate the adjustment plate 6 by the staff to keep the circular groove 7 opened on the outer wall of the adjustment plate 6 and the clamping plate 5 through and able to maintain a position of appropriate size, so that the microparticles can smoothly enter the Venturi tube 1, and at the same time, under the action of the sealing ring 9, the delivery pipe 3, the adjustment column 4 and the feed pipe 8 can be Good air tightness is maintained to avoid leakage of particles and waste. When the particles enter the venturi tube 1, the air will pass through the venturi tube 1 quickly, so that the particles entering the venturi tube 1 can be carried quickly through the universal curved tube 2 and sprayed onto the surface of the object for processing. When the venturi tube needs to be maintained, the staff first presses the limit block 15 to move inside the installation box 14 under manual operation to compress the limit spring 16, so that the limit block 15 is taken out from the limit groove 13, and finally the venturi tube is disassembled from the gas pipeline, which makes it easier for the staff to maintain and service it, thereby improving work efficiency.
