This application makes further improvements on this existing subject. For details, please refer to the disclosed technology below; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the above-mentioned design can make the tea withering machine have a good withering effect when used, and can effectively improve the quality of tea, but the stirring mechanism 3 is a fixed structure design. Since the tea leaves need to be evenly heated and turned during the withering process, the fixed stirring method may cause some tea leaves to have a short contact time with high temperature or insufficient contact surface, thereby failing to achieve a uniform withering effect. At the same time, a longer withering time may be required to ensure that all tea leaves are fully withered, thus reducing the efficiency of withering". In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a moving component 4 and a collecting component 5 are added to the present application document, and the electrical equipment involved in this product are all powered by an external power supply.

When it is necessary to discharge the tea leaves inside the cylinder 2, first place the storage box (not shown in the figure) under the cylinder 2, and use the storage box to squeeze the collection box 501. At the same time, the collection box 501 slides inside the support seat 1, and drives the L-shaped plate 502 to slide on the surface of the guide rod 503, and compresses the spring 504. Through the setting of the spring 504, it is convenient for the spring 504 to rebound after the storage box is removed later, and drive the collection box 501 to move to the bottom of the cylinder 2 again, so that the staff does not need to frequently carry it, thereby improving the use effect of the device.

[0046] The working principle and use process of the utility model: when using the hot air circulation tea withering machine, first put the tea leaves into the cylinder 2, and start the stirring mechanism 3 to stir the tea leaves, and start the servo motor 404 at the same time, so as to drive the winding roller 402 to rotate, and the steel cable 403 is wound by the rotation of the winding roller 402, and as the steel cable 403 is wound, the connecting plate 405 is driven to move upward, and the steel cable 406 is driven to move upward by the connecting plate 405, and the cylinder 2 can be moved upward by the steel cable 406, and the cylinder 2 slides on the surface of the limit rod 410 through the sliding block 409.
