[0029] During use, the steel balls fall from the ball inlet 11 onto the screening mechanism 2, and the spraying mechanism 3 can spray and rinse the surface of the steel balls while passing through the screening mechanism 2. After rinsing, they are screened through the end of the screening mechanism 2 and fall into a container for collecting steel balls of different sizes. The setting of the screening mechanism 2 can effectively replace the workers' sorting of steel balls and improve the sorting efficiency. The setting of the spraying mechanism 3 can effectively rinse the cement raw materials on the surface of the steel balls, effectively remove the cement raw materials on the surface of the steel balls, and make it more convenient for the subsequent recycling of the steel balls.

[0030] Reference Figure 2-4 The screening mechanism 2 includes a shaking assembly 21 and a screening plate 22. The shaking assembly 21 is located below the goal hole 11. The screening plate 22 is fixedly arranged on the side wall of the machine body 1, and the screening plate 22 is located below the discharge end of the shaking assembly 21.

[0031] More specifically, the shaking assembly 21 includes a shaking net 211, a cam 212, a rotating rod 213, and a motor 214. The cam 212 is fixedly mounted on the rotating rod 213, and the rotating rod 213 is rotatably mounted in the body 1. The shaking net 211 slides up and down on the inner wall of the body 1, and the shaking net 211 abuts against the top of the cam 212. The motor 214 is fixedly mounted on the outer wall of the body 1, and the motor 214 drives the rotating rod 213 to rotate.

[0032] More specifically, a buffer pad 215 is provided on the shaking net 211. The buffer pad 215 is located below the goal hole 11 and can effectively buffer the steel ball, reduce the direct collision between the steel ball and the shaking net 211, and extend the service life of the shaking net 211.

[0033] More specifically, the screening plate 22 extends to the outside of the body 1, and a plurality of ball discharge ports 221 of different sizes are formed in the screening plate 22, the sizes of the ball discharge ports 221 increase from inside to outside, and the part of the screening plate 22 located in the body 1 is provided in a mesh shape, so that the falling steel balls are preferentially screened for small ones, making the screening more accurate.

[0034] In use, the steel balls fall from the ball inlet 11 onto the buffer pad 215, and then fall onto the shaking net 211 after being relieved by the buffer pad 215. The two sides of the shaking net 211 are provided with sliding blocks and sliding grooves on the two sides of the inner wall of the body 1. When the rotating rod 213 is driven to rotate, the cam 212 rotates to make the shaking net 211 ascend and descend in the body 1, so that part of the cement raw materials on the steel balls fall to the bottom of the body 1, are washed by the spraying mechanism 3, and then fall onto the screening plate 22 and are discharged in turn through the ball discharge ports 221 on the screening plate 22.

[0035] Referring to Figure 1-3 , the spraying mechanism 3 includes a plurality of spraying pipes 31, a water pump 32, and a water storage tank 33. The water storage tank 33 is fixedly arranged on the side wall of the body 1, the water pump 32 is fixedly arranged on the top of the body 1, and the plurality of spraying pipes 31 are fixedly arranged on the top of the inner wall of the body 1 and face the shaking assembly 21. One end of the water pump 32 communicates with the plurality of spraying pipes 31, and the other end of the water pump 32 communicates with the bottom of the water storage tank 33.

[0036] In use, the water pump 32 takes water from the water storage tank 33 and sprays it through the spraying pipes 31. The spraying pipes 31 are inclined towards the upper side of the shaking net 211, so as to clean the surface of the falling steel balls and effectively remove the cement raw materials adhered to the surface of the steel balls.

[0037] Referring to Figure 2 , the bottom of the body 1 is provided with a liquid discharge port, and the bottom of the body 1 is inclined, so as to effectively facilitate the discharge of the liquid for cleaning the surface of the steel balls.
