[0003] 1. The rack is the support structure of the winnower, which is usually welded by metal materials, and provides stable physical support for the entire winnower.

[0004] 2. The air pipe is a channel for air circulation inside the winnower.

[0005] 3. The fan is a key component of the winnower for generating airflow, which mainly consists of a motor, an impeller and a housing. The motor provides power for the fan to drive the impeller to rotate.

[0006] 4. The feeding mechanism is a component for conveying materials to the winnower.

[0007] During the winnowing process of black tea, the airflow discharged by the winnower through the air pipe may carry light impurities, and a storage bag needs to be installed outside the air pipe to collect these impurities for subsequent impurity treatment. When installing the collection bag, the hanging ring of the collection bag is hung on the metal hook.

[0008] However, in actual operation, due to factors such as vibration and unstable airflow during the operation of the winnower, the storage bag is prone to falling off, and when the storage bag itself does not have a hanging ring, it is difficult to firmly install it on the air pipe, which affects the collection effect of impurities. To solve this problem, the application proposes a solution by adding a clamping mechanism at both ends of the air pipe. UTILITY MODEL CONTENT
