[0035] Working principle: when in use, tea leaves are conveyed into the fermentation box 1 through an automatic feeding device such as a conveying belt. After the tea leaves are piled up, water is sprinkled on the tea leaves through the watering frame 14 and the watering holes 15 on the watering frame 14 until water flows out from the water permeable holes of the fermentation box 1.

[0036] Then, the watering is stopped, and fermentation is carried out. After a certain period of fermentation, when it is necessary to turn over, the motor 2 is started, the output shaft of the motor 2 drives the first screw rod 3 to rotate, the first screw rod 3 drives the support frame 5 to slide along the length direction of the fermentation box 1. The support frame 5 drives the second screw rod 6 to move along the length direction of the fermentation box 1, and the second screw rod 6 drives the first gear 9 to move along the length direction of the fermentation box 1. Since the first gear 9 is in meshing cooperation with the first rack 8, the first gear 9 rotates.

[0037] In the process of rotation of the first gear 9, the second screw rod 6 is driven to rotate. The second screw rod 6 drives the sliding block 12 to reciprocally slide along the width direction of the fermentation box 1, and the sliding block 12 drives the agitator shaft 4 to reciprocally move along the width direction of the fermentation box 1. The agitator shaft 4 drives the second gear 16 to reciprocally move along the width direction of the fermentation box 1, and since the second gear 16 is in meshing cooperation with the second rack 13, the second gear 16 rotates.

[0038] In the process of rotation of the second gear 16, the agitator shaft 4 is driven to rotate. The agitator shaft 4 drives the spiral blade 10 to carry out turning-over operation on the tea leaves in the fermentation box 1. When the turning-over operation is completed, the motor 2 is turned off.

[0039] During the course of the turning operation, the helical flight 10 does not contact the sprinkler frame 14.
