[0023] like Figures 1 to 3 As shown, a shot blasting cleaning device for a shot blasting machine comprises an upper cleaning box 1 and a lower cleaning box 2, a support portion 3 for connecting and fixing the upper cleaning box 1 and the lower cleaning box 2 is arranged on the outer side of the upper cleaning box 1, a feeding hopper connected to the inner cavity of the upper cleaning box 1 is installed on the top of the upper cleaning box 1, a feeding screen plate 10 for high-speed projectiles to fall is fixedly connected to the inner wall surface of the upper cleaning box 1, a through hole is opened on the feeding screen plate 10, a disassembly portion 9 is arranged inside the through hole, a motor 4 for driving the disassembly portion 9 is installed on the top of the upper cleaning box 1, a plurality of cleaning rollers 5 for cleaning high-speed projectiles are arranged on the outer wall surface of the disassembly portion 9, a rotating shaft 7 is detachably installed on the other end of the disassembly portion 9, and a plurality of cleaning rollers 8 for cleaning high-speed projectiles are rotatably installed on the outer wall surface of the rotating shaft 7;

[0024] In order to ensure the stability of the disassembly and assembly part 9 during rotation, the plurality of cleaning rollers 5 and the plurality of cleaning rollers 8 are respectively distributed circumferentially on the outer sides of the disassembly and assembly part 9 and the rotating shaft 7;

[0025] Specifically, the driving motor 4 can drive the disassembly and assembly part 9 to rotate, and drive the rotating shaft 7 to rotate accordingly, so as to drive multiple cleaning rollers 5 and multiple cleaning rollers 8 to rotate synchronously. During the rotation, the dust, debris and the like adhered to the surface of the high-speed projectile can be cleaned. Compared with manual cleaning, the cleaning efficiency is effectively improved, the labor workload of workers is reduced, the investment in labor costs is reduced, the production efficiency of the enterprise is guaranteed, and the processing cycle required for sand removal, core removal and cleaning of castings is shortened. The set cleaning roller 5 can not only clean the outer surface of the high-speed projectile, but also push the high-speed projectile to the holes of the unloading screen plate 10 during the rotation, to ensure that the high-speed projectile can smoothly fall into the inner cavity of the lower cleaning box 2.

[0026] like Figure 2 As shown, the lower cleaning box 2 is provided with a chip removal bucket 6 for collecting high-speed projectiles dropped from the unloading screen plate 10. The bottom surface of the inner cavity of the chip removal bucket 6 is fixedly connected to the movable end of the rotating shaft 7. The bottom of the chip removal bucket 6 is rollingly connected to the bottom surface of the lower cleaning box 2 through rolling balls. A plurality of chip discharge holes are provided on the bottom surface of the lower cleaning box 2 and the outer wall surface of the chip removal bucket 6. A brush 11 is bonded to the bottom of the chip removal bucket 6. The upper surface of the chip removal bucket 6 is located vertically below the unloading screen plate 10, and the distance between the two is consistent with the radius of the high-speed projectile.

[0027] Specifically, the chip removal bucket 6 is arranged to collect the high-speed projectiles falling from the unloading screen plate 10, so that when the disassembly and assembly part 9 drives the rotating shaft 7 to rotate at high speed, the rotating shaft 7 can drive the chip removal bucket 6 fixedly connected to its bottom to rotate, thereby ensuring that the dust, debris, etc. swept off the surface of the high-speed projectiles under the action of centrifugal force can be effectively thrown out, so that with the cooperation of gravity and the brush 11, the thrown debris can be discharged outward from the chip discharge hole on the lower cleaning box 2, reducing the trouble of manually cleaning the inner cavity of the lower cleaning box 2.

[0028] like Figure 1 As shown, the support part 3 includes four brackets 301, and four circumferentially distributed brackets 301 are arranged on the outer side of the upper cleaning box 1. An upper positioning block 302 fixedly connected to the upper end of the bracket 301 is welded on the outer wall surface of the upper cleaning box 1, and a lower positioning block 303 corresponding to the upper positioning block 302 is welded on the outer wall surface of the lower cleaning box 2. A fastening screw is threadedly connected between the upper positioning block 302 and the lower positioning block 303 corresponding to each other;

[0029] Specifically, by placing the upper cleaning box 1 on the top of the lower cleaning box 2, the bottom surface of the upper cleaning box 1 is in contact with the upper surface of the lower cleaning box 2, and the upper positioning block 302 corresponds to the lower positioning block 303, and then the fastening screw is threadedly connected between the upper positioning block 302 and the lower positioning block 303 corresponding to each other, the purpose of fixing the upper cleaning box 1 on the top of the lower cleaning box 2 can be achieved, and the structure is simple and easy to operate.

[0030] like Figure 3 As shown, the disassembly and assembly part 9 includes a column, a column is arranged inside the through hole, a mounting column 901 is fixedly installed on the top of the column, a plurality of side plates 902 rotatably connected to the movable end of the cleaning roller 5 are arranged on the outside of the mounting column 901, two inverted "L"-shaped protrusions 903 are arranged on the side of the side plate 902 away from the cleaning roller 5, and a clamping groove 904 for mortise and tenoning the protrusions 903 is opened on the outer wall surface of the mounting column 901;

[0031] Specifically, by vertically mortising the protrusion 903 downward into the inside of the locking groove 904, the side plate 902 can be limited and fixed, so that the cleaning roller 5 can rotate at high speed with the mounting column 901 as the center when the mounting column 901 rotates, thereby achieving the purpose of cleaning the surface of the high-speed projectile.

[0032] like Figure 3 As shown, the cleaning roller 5 is connected to a connecting plate 905 through a bearing, and a ball 906 whose outer surface contacts the upper surface of the unloading screen plate 10 is rollingly connected to the bottom of the connecting plate 905;

[0033] Specifically, the connecting plate 905 and the ball bearing 906 are provided to support the cleaning roller 5, thereby ensuring the stability of the cleaning roller 5 during installation and use, preventing the active end of the cleaning roller 5 from tilting due to lack of support, and ensuring the cleaning effect on high-speed projectiles.

[0034] In summary: the driving motor 4 can drive the disassembly and assembly part 9 to rotate, and drive the rotating shaft 7 to rotate accordingly, so that the multiple cleaning rollers 5 and the multiple cleaning rollers 8 can be driven to rotate synchronously. During the rotation, the dust, debris, etc. adhered to the surface of the high-speed projectile can be cleaned. Compared with manual cleaning, the cleaning efficiency is effectively improved, the labor workload of workers is reduced, the investment in labor costs is reduced, the production efficiency of the enterprise is guaranteed, and the processing cycle required for sand dropping, core removal and cleaning of castings is shortened.
