[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0019] like Figure 1-3 As shown, a constant temperature and humidity tea fermentation device comprises a box body 1, a support frame 2 is arranged in the box body 1, at least one tray 3 is arranged on the support frame 2, and tea leaves to be fermented are placed in the tray 3; a pulley block 4 is arranged in the box body, a steel wire rope 5 is wound around the pulley block 4, a traction block 6 is fixedly connected to the steel wire rope 5, a turning rod 7 is fixed to the bottom of the traction block 6, the lower end of the turning rod 7 is located in the tray 3 and turns the tea leaves in the tray 3; a temperature sensor (not shown in the figure) and a humidity sensor (not shown in the figure) are arranged in the box body 1, and the temperature sensor and the humidity sensor are electrically connected to the PLC controller respectively.

[0020] Specifically, the pulley group 4 includes a first pulley 41, a second pulley 42, a third pulley 43, a fourth pulley 44, a fifth pulley 45, a sixth pulley 46, a seventh pulley 47, an eighth pulley 48, a ninth pulley 49, a tenth pulley 410, an eleventh pulley 411 and a twelfth pulley 412. One end of the wire rope 5 passes around the first pulley 41, the second pulley 42, the third pulley 43, the fourth pulley 44, the fifth pulley 45, the sixth pulley 46, the seventh pulley 47, the eighth pulley 48, the ninth pulley 49, the tenth pulley 410, the eleventh pulley 411 and the twelfth pulley 412 in sequence and is connected to the other end of the wire rope 5 to form a closed loop.

[0021] In the utility model, the first pulley 41 is first driven to rotate, and the first pulley 41 drives the steel wire rope 5 and other pulleys to move. When the traction block 6 moves driven by the steel wire rope 5, the turning rod 7 moves accordingly and turns the tea leaves in the tray 3. This design not only realizes the automatic turning of the tea leaves, but also enables the tea leaves to be evenly heated and moistened during the fermentation process, thereby improving the fermentation quality of the tea leaves.

[0022] The temperature sensor and humidity sensor are electrically connected to the PLC controller respectively, forming an intelligent control system. By real-time monitoring of the temperature and humidity in the box 1, the PLC controller can accurately adjust the environmental conditions to always maintain a constant temperature and humidity environment in the box 1, thereby ensuring that the tea leaves are fermented in the best environment.

[0023] The transmission mechanism of the utility model only adopts a set of pulleys 4 and a driving mechanism (motor) to realize the turning of tea leaves. Compared with the prior art, the utility model is simpler in design and saves production costs.

[0024] Furthermore, the box body 1 includes a top plate 14 and a bottom plate 12, and two side plates 11, a back plate 13 and a door plate (not shown) are fixedly arranged between the top plate 14 and the bottom plate 12. The top plate 14, the bottom plate 12, the two side plates 11, the back plate 13 and the door plate are firmly combined to form a stable and relatively closed box body 1, which is essential for maintaining a constant temperature and humidity. The environment inside the box body 1 is isolated from the outside world, which can reduce the impact of external environmental changes on the tea fermentation process, thereby ensuring the quality of tea fermentation.

[0025] Furthermore, the support frame 2 includes a side sliding plate 21 and a support plate 22. The side sliding plate 21 is arranged parallel to the side plate 11. The support plate 22 is fixed to one side of the side sliding plate 21. The tray 3 is slidably arranged on the support plate. In order to improve the fermentation efficiency of tea leaves, the utility model is equipped with four support plates on one side of the side sliding plate, and four trays 3 are arranged accordingly.

[0026] Furthermore, the bottom of the support frame 2 is connected to the electric cylinder 8, and the electric cylinder 8 is fixed on the base plate.

[0027] Furthermore, a slider 10 is provided on one side of the side sliding plate, a slide rail 9 is installed on the inner wall of the side plate 11 , and the slider 10 cooperates with the slide rail 9 .

[0028] The electric cylinder 8 is started to drive the support frame 2 to rise and fall, thereby realizing accurate control of the height of the tray 3. The arrangement of the slider 10 and the slide rail 9 improves the stability of the support frame 2 in rising and falling.

[0029] Furthermore, a through hole 13 is provided in the traction block 6 , and the steel wire rope 5 passes through the through hole 13 and is fixed to the traction block by bolts 12 . This design makes it easy to adjust the position of the traction block on the steel wire rope 5 .

[0030] Furthermore, the bottom of the turning rod 7 is arc-shaped, so that the turning rod can turn the tea leaves more smoothly, reducing damage to the tea leaves and improving the quality of the tea leaves.

[0031] When in use, the tea leaves to be fermented are evenly spread on the tray 3, and then the tray 3 is pushed to slide to a suitable position on the support plate 22; the electric cylinder 8 is turned on, the tray rises, and the lower end of the turning rod 7 is located in the tea leaves; then the motor is turned on, the steel wire 5 starts to move, and the turning rod is controlled to move back and forth in the tea leaves, realizing the function of turning the tea leaves and fermenting them at the same time. After the fermentation is completed, the electric cylinder drives the tray to descend, and then the tray is pulled out, and the fermented tea leaves are placed in a suitable position.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
