In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3 The utility model shows a schematic diagram of the entire structure of a Liubao tea fermentation tank, please refer to Figure 1-Figure 3 A Liubao tea fermentation tank according to the present embodiment includes a tank body 100 as the main body of the fermentation tank. The tank body 100 is driven by a driving device to rotate axially. A plurality of feed ports 110 equipped with a cover are arranged on the outside of the tank body 100 along its length direction. A material guide cover 200 is provided at one end of the tank body 100 and is communicated with the tank body. A plurality of flat spiral leaves 210 are distributed around the inner side of the material guide cover 200, and the flat spiral leaves 210 extend to the outer end of the material guide cover 200. A rotating shaft 300 extending to both ends of the tank body 100 is rotatably installed at the axis center inside the tank body 100. A spiral blade 310 close to the inner wall of the tank body 100 is provided on the outer side of the rotating shaft 300, and the rotating shaft 300 is also driven by the driving device to rotate.

[0021] The outer end of the material guide cover 200 is also provided with a cover mouth 220, and the flat spiral blade 210 extends to the inner side of the cover mouth 220. The outer end of the cover mouth 220 is also matched with a cover plate 230. It can be understood that the cover plate 230 is sealed to the cover mouth 220 during fermentation, and it is opened when it is necessary to discharge the material. When in use, when the fermented tea leaves in the tank body 100 are continuously pushed into the material guide cover 200 by the spiral blade 310, the rotating tank body 100 can drive the material guide cover 200 and the flat spiral blade 210 to rotate synchronously, and the inclined flat spiral blade 210 can make the tea leaves that fall between adjacent blades slide forward, so that the tea leaves are continuously discharged outward through the cover mouth 220, which has the characteristics of uniform discharge, convenience and speed.

[0022] Specifically, in the present embodiment, a motor 1 320 is installed at the other end of the tank body 100 and the output shaft is connected to one end of the rotating shaft 300. A support frame 120 is also fixed at the junction of the inner side of the tank body 100 and the material guide cover 200 and is rotatably installed with one end of the rotating shaft 300 through a bearing. When the fermented tea leaves need to be discharged, the tank body 100 and the material guide cover 200 are driven by the motor 2 to rotate at a uniform speed. At the same time, the motor 1 320 will drive the rotating shaft 300 and the spiral blade 310 to rotate. It should be noted that the rotation direction of the spiral blade 310 is consistent with the direction of the tank body 100, but the rotation speed of the spiral blade 310 is greater than the rotation speed of the tank body 100. In this way, the tea leaves in the tank body 100 will be continuously pushed into the material guide cover 200 by the spiral blade 310, and the flat spiral leaf 210 in the material guide cover 200 can slide the tea leaves falling between adjacent leaves forward, so that the tea leaves are continuously discharged outward. The structure is simple, the design is reasonable, the material discharge is uniform, and it is convenient and fast, which brings convenience to the processing operation of tea leaves.

[0023] Furthermore, guide rails 130 are fixed at both ends of the outer side of the tank body 100, and directional wheels 400 are provided on both sides of the lower part of the guide rails 130 for sliding matching with the guide rails 130. With the cooperation of the guide rails 130 and the directional wheels 400, the tank body 100 can be positioned and stabilized when it is stationary or rotating; a gear ring 140 is also provided in the middle section of the outer side of the tank body 100, and a gear 500 is provided at the lower end of the tank body 100 for meshing with the inner teeth of the gear ring 140, and the gear 500 is driven to rotate by the motor 2 510. It should be noted that during normal fermentation and stirring of tea leaves, the motor 2 510 will drive the gear ring 140 and the tank body 100 to rotate through the gear 500, so that the tea leaves in the tank are continuously turned over and mixed, and at this time, the motor 1 320 does not participate in the rotation of the spiral blade 310, because the tea leaves do not need to be pushed out at this time.

[0024] Furthermore, a base plate seat 600 is provided below the tank body 100, and the upper part of the base plate seat 600 has a U-shaped bracket for positioning and installing the directional wheel 400 and the gear 500. The entire fermentation tank device can be positioned and installed through the provided base plate seat 600, making it more stable during operation.

[0025] In summary, in a Liubao tea fermentation tank according to the present embodiment, when in use, unfermented tea leaves are introduced into the tank body 100 through the feed port 110. When the fermentation is completed and the fermented tea leaves need to be discharged, the tank body 100 and the material guide cover 200 are driven to rotate at a uniform speed by motor 2, and at the same time, motor 1 320 drives the rotating shaft 300 and the spiral blade 310 to rotate. It should be noted that the rotation direction of the spiral blade 310 is consistent with the direction of the tank body 100, but the rotation speed of the spiral blade 310 is greater than the rotation speed of the tank body 100. In this way, the tea leaves in the tank body 100 will be continuously pushed into the material guide cover 200 by the spiral blade 310, and the flat spiral leaf 210 in the material guide cover 200 can slide the tea leaves falling between adjacent leaves forward, so that the tea leaves are continuously discharged outward, and the discharge is uniform, convenient and fast, which brings convenience to the processing operation of tea leaves.
