The rotating shaft 207 is rotatably connected to the screening box 100. Cam 208s are arranged on both sides of the rotating shaft 207. The cam 208s on both sides are arranged staggeredly. When the cam 208 rotates, it strikes the screening plate 201 above to generate vibration. A second motor 206 is arranged on one side of the rotating shaft 207. The two rotating shafts 207 are driven by a belt. A second cylinder 209 is arranged between the two rotating shafts 207. The second cylinder 209 is arranged on one side of the screening plate 201 and is used to lift the screening plate 201 to discharge the screened diamonds. A blanking bin 212 is arranged on one side of the screening plate 201 close to the first cylinder 203 for discharging diamonds. A blanking plate 210 is arranged below the rotating shaft 207. The blanking plate 210 is arranged in an inclined downward direction. A fixing frame 213 is arranged on one side of the blanking plate 210. A material storage box 211 is arranged inside the fixing frame 213. By mutually adjusting the distance between the screening holes and the adjustment holes in the screening assembly, the diameter of the screening holes is adjusted, so as to screen diamonds of different sizes and volumes, improving the flexibility of the device and its applicable range. Then, through the vibration assembly, the diamonds during the screening process are vibrated irregularly, constantly changing the positions of a large area of diamonds, enabling better screening and discharging of the diamonds, expanding the range of diamond screening, accelerating the diamond screening speed, and improving the diamond screening quality;

[0029] In this embodiment: The cleaning mechanism 300 includes a cleaning tank 301, a water pump 302, a water spray pipe 303, a third cylinder 304, a third motor 305, a cleaning disc 306, a material holding frame 307, and a waste frame 308. The cleaning tank 301 is provided at the inner bottom end of the screening tank 100. A water pump 302 is provided on one side of the cleaning tank 301. A plurality of water spray pipes 303 are arranged around between the water pump 302 and the cleaning tank 301. A plurality of water spray nozzles are provided on the water spray pipe 303. The waste frame 308 is slidably installed at the inner bottom end of the cleaning tank 301. The material holding frame 307 is provided above the waste frame 308. The material holding frame 307 is slidably connected to the cleaning tank 301. A plurality of water leakage holes are formed on the surface of the material holding frame 307. The cleaning disc 306 is provided above the cleaning tank 301. The third motor 305 is provided at the upper end of the cleaning disc 306. The third cylinder 304 is provided above the third motor 305. The cleaning liquid is pumped into the water spray pipe 303 by the water pump 302, and the cleaning liquid is sprayed onto the diamond through a plurality of water spray nozzles to clean it. Then, the third cylinder 304 is used to push the cleaning disc 306 to move downward, and the rotation of the third motor 305 drives the cleaning disc 306 to rotate, so as to scrub the surface of the diamond in all directions. The waste liquid after cleaning flows into the waste frame 308, and the cleaned diamond remains in the material holding frame 307, improving the cleanliness of the diamond surface and the production quality.

[0030] Working principle: First, a large number of diamonds to be screened are poured into the feeding bin 212. The spiral auger 205 is driven to rotate by the kinetic energy of the first motor 204 to conduct spiral feeding of the diamonds, causing them to fall onto the screening plate 201. Then, driven by the kinetic energy of the second motor 206 and using the transmission of the belt, two rotating shafts 207 are driven to rotate simultaneously, thereby driving the cams 208 on both sides to rotate. Through the staggered arrangement of the two cams 208, the screening plate 201 is subjected to irregular knocking vibration, making the diamonds on its surface move irregularly, expanding the screening area, enabling better screening and feeding of the diamonds. Then, the first cylinder 203 pulls the matching plate 202 to move horizontally to adjust the distance between the screening holes and the adjustment holes, thereby screening diamonds of different sizes, improving the screening range of the device and its flexibility. After screening, the diamonds that do not meet the size fall onto the feeding plate 210 and finally slide into the material receiving box 211 for collection. The diamonds that meet the size remain on the surface of the screening plate 201. Then, the second cylinder 209 on one side extends upward to lift one side of the screening plate 201, causing the diamonds on its surface to flow obliquely towards the feeding bin 212 and fall into the cleaning tank 301 through the feeding bin 212. Then, the water pump 302 pumps the cleaning liquid into the spray pipe 303, and the cleaning liquid is sprayed towards the diamonds through multiple spray heads to clean them. Then, the third cylinder 304 pushes the cleaning disc 306 to move downward, and the rotation of the third motor 305 drives the cleaning disc 306 to rotate, thereby scrubbing the surface of the diamonds comprehensively. The waste liquid after cleaning flows into the waste frame 308, and the cleaned diamonds remain in the material receiving frame 307, improving the cleanliness of the diamond surface and the production quality. Finally, the screening and cleaning operation of the diamonds is completed.

[0031] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present utility model.
