The conveying assembly 4 includes a conveyor belt 414; and the conveying assembly 4 also includes an adjustment mechanism for controlling the height of the end of the conveyor belt 414 to achieve its angle adjustment.

[0033] During specific implementation, after the conveying is completed, screening is required.

The long ridge 212 on the roller 204 will support the vibration block 206, and the connecting plate 207 will move upward. However, due to the compression spring 205 between the connecting plate 207 and the base 201, after the position of the long ridge 212 on the roller 204 is turned, it will move back due to the rebound force of the compression spring 205, causing the connecting plate 207 to move downward. Every time the roller 204 rotates, the connecting plate 207 will move back and forth to achieve a vibration effect. The cemented carbide raw material in the lower bin 209 enters the screening frame 208 through the lower material port, and is filtered by the filter screen 211 in the screening frame 208, so that the screened and separated raw materials are introduced into the material barrel 3 through the discharge pipe 210.

[0035] A long convex strip 212 is arranged on the roller shaft 204, and a plurality of compression springs 205 are connected to the base 201. The other end of the compression spring 205 is connected to the bottom of the connecting plate 207. A vibration block 206 is connected to the bottom of the connecting plate 207.

A filter screen 211 is arranged in the screening frame 208. A lower material bin 209 is arranged on the screening frame 208. The compression spring 205 is used to achieve a vibration effect through the long convex strip 212 and the vibration block 206, so that the cemented carbide raw materials in the screening frame 208 are screened.
