Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , 2 As shown in Figures 3 and 4, the utility model provides a technical solution: a crawler-type sandblasting machine shot blasting device, comprising: a shell 1 with sound insulation material inside, the sound insulation material is sound-absorbing foam, sound insulation board or sound insulation felt; a fan blade 11 is rotatably placed in the shell 1, and a driving motor 12 for driving the fan blade 11 is fixedly installed on the outside of the shell 1; a guide material pipe 9 is inserted into the shell 1 and is located in the middle of the fan blade 11, and a sealing fixed disk 8 is fixedly connected to the middle of the guide material pipe 9, and a discharge hole 13 is opened at one end of the guide material pipe 9 for changing the discharge direction; an angle fixing mechanism is placed on the outside of the shell 1, and the angle fixing mechanism includes a limit toothed disk 2 rotatably set on the outside of the shell 1, and a plurality of extruded oblique teeth 17 are equidistantly fixed to the middle of the limit toothed disk 2, and a sliding positioning plate 6 for fixing the sealing fixed disk 8 is slidably connected to the inner side of the limit toothed disk 2, and the inner side of the sliding positioning plate 6 is an inclined surface structure, which is along the direction away from the center of the sealing fixed disk 8, and the height gradually decreases.

[0024] It should be noted that the utility model adjusts the angle of the guide material tube 9 as needed, and rotates the limiting toothed disk 2 by rotating the worm 5, so that the extrusion bevel gear 17 is separated from the sliding positioning plate 6, and the sliding positioning plate 6 is slid from the outer side of the sealing fixed disk 8 along the T-shaped track 7, so that the sliding positioning plate 6 is separated from the sealing fixed disk 8, and the guide material tube 9 is rotated to the specified angle according to the position pointed by the angle pointer 18, and then the extrusion bevel gear 17 is squeezed and pressed against the sliding positioning plate 6 by rotating the limited toothed disk 2, and the angle of the guide tube is easily adjusted by rotating the worm and then the limiting toothed disk, without using additional tools or disassembling other parts, making the adjustment process simpler and more efficient; the extrusion bevel gear and the sliding positioning plate can provide a fixing force to ensure that the guide tube is firmly fixed at the set angle position without accidentally moving or loosening, and the worm gear transmission system has high reliability and durability, can work stably for a long time without easily failing or being damaged, and because the angle adjustment and fixing of the guide tube are achieved by the worm gear transmission system, no other tools are required to disassemble other workpieces or components.

[0025] See also Figure 4 As shown, a cover plate 15 is fixedly connected to the top of the shell 1 , a discharge port 16 is opened at the bottom of the shell 1 , and an anti-collision plate 14 is fixedly connected to the inside of the shell 1 .

[0026] It should be noted that the cover plate 15 of the utility model is fixed on the top of the shell 1, which is used to cover the upper part of the shot blasting machine, prevent abrasives and debris from leaking out from the top, and provide protection for the internal operating space. The discharge port is located at the bottom of the shell 1, which is used to discharge gold particles so that they can be smoothly thrown out of the shot blasting machine at high speed. The anti-collision plate is fixedly connected to the inside of the working room of the shell 1, which is used to protect the internal structure of the shot blasting machine from wear and damage, and prevent the workpiece from colliding with the internal wall of the shot blasting machine, thereby extending the service life of the shot blasting machine.

[0027] See also Figure 1 , 4 As shown, the output end of the driving motor 12 is fixedly connected to the fixed connection disk 10, and the fan blades 11 are fixedly connected to the middle part of the fixed connection disk 10 at equal distances.

[0028] It should be noted that the drive motor 12 of the utility model drives the fixed connection disk 10 to rotate, and the fixed connection disk 10 drives the fan blades 11 to rotate. The rotation of the fan blades generates airflow and pushes the abrasive or cleaning medium to the surface of the workpiece, thereby realizing shot blasting or cleaning operations. By fixing the fan blades equidistantly to the middle of the fixed connection disk, it can ensure that the fan blades remain balanced during rotation, reduce vibration and instability, and thus improve the working efficiency and stability of the shot blasting machine.

[0029] See also Figure 2 , 3As shown, the outer side of the shell 1 is fixedly connected with a limit plate 3 at an equal angle, the limit gear disc 2 is rotatably connected to the inner side of the limit plate 3, the outer side of the shell 1 is fixedly connected with a fixed box 4, the inside of the fixed box 4 is rotatably connected with a worm 5, the outer side of the limit gear disc 2 is provided with a thread used in conjunction with the worm 5, the worm 5 is meshingly connected with the limit gear disc 2, the outer side of the shell 1 is fixedly connected with a T-shaped track 7, the T-shaped track 7 is slidably connected to the outer side of the sliding positioning plate 6, the outer side of the sealing fixed plate 8 is fixedly connected with an angle pointer 18, and one side of the shell 1 is provided with a scale used in conjunction with the angle pointer 18.

[0030] It should be noted that when the utility model adjusts the angle of the guide material tube 9, the worm 5 drives the limit toothed disk 2 to rotate inside the limit plate 3. When the limit toothed disk 2 rotates, the Shudie extrusion bevel gear 17 is separated from the sliding positioning plate 6. When the sliding positioning plate 6 is not squeezed by external force, the sliding positioning plate 6 is separated from the sealing fixed disk 8. Then the guide material tube 9 is rotated so that the angle pointer 18 points to the specified scale line. Then the worm 5 is rotated so that the worm 5 drives the extrusion bevel gear 17 to rotate through the limit toothed disk 2. The extrusion bevel gear 17 is a triangular structure, and one side of the beveled edge is in contact with the sliding positioning plate 6 for extrusion, so that the sliding positioning plate 6 is squeezed against the outside of the sealing fixed disk 8, and the top of the inner wall of the sliding positioning plate 6 is squeezed against the outside of the sealing fixed disk 8 to achieve compression and fixation.
