When the unloading port and the discharge port rotate to coincide with the feed outlet, the feed falls from the fixed bottom plate into the pelletizing box for pelletizing. After multi-stage transmission, the rotation speed of the transmission gear is much lower than the rotation speed of the active shaft, so that the pelletizing and unloading time can be staggered, so that the feed in the storage box can be fully stirred without affecting the pelletizing process.

[0021] 3.

The active wheel is driven by the pellet motor to rotate, and the active wheel drives the driven wheel and the active shaft connected to it to rotate through the transmission belt during the rotation process. The active shaft drives the granulation plate and the two sets of extrusion wheels on the rolling device to rotate during the rotation process. During the rotation of the granulation plate, the feed above it is extruded into the granulation holes on the granulation plate under the extrusion of the extrusion wheels.
