[0022] Then, the air pump connected to the ventilation and dust removal mechanism sucks air into the tank body 1 at high speed and starts the driving mechanism at the same time. The driving mechanism drives the tank body 1 to rotate. At this time, the wheat inside the tank body 1 moves, and the dust attached to the wheat escapes in the tank body 1. With the help of the gas introduced, the escaped dust can be quickly discharged, thereby realizing the rapid dust removal operation of the wheat.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The ventilation and dust removal mechanism includes a rotating tube 3 symmetrically fixedly connected to both sides of the outer periphery of the tank body 1.
