Description

Technical Field

[0001] This utility model relates to the field of tea leaf turning technology, specifically a device for turning fermented tea leaves in Liubao tea. Background Technology

[0002] Liubao tea belongs to the category of dark tea. Its unique "red, strong, aged, and mellow" quality characteristics are mainly due to the pile fermentation process. In this process, the tea leaves are piled in fermentation tanks or fermentation areas. Under suitable temperature and humidity conditions, a series of complex biochemical changes, such as microbial action, heat and humidity, and enzymatic reactions, form the unique color, aroma, and taste of Liubao tea. During this process, the piled tea leaves need to be turned over regularly to dissipate heat, allow air to pass through, and ensure even fermentation.

[0003] Currently, in some Liubao tea production enterprises and workshops, manual turning is still commonly used. Workers use tools such as shovels and rakes, which is extremely labor-intensive. The working environment is hot and humid, the turning efficiency is low, and the uniformity and effect of turning are highly dependent on the worker's experience, resulting in poor consistency and quality fluctuations. Utility Model Content

[0004] The purpose of this invention is to provide a device for turning over fermented Liubao tea leaves, in order to solve the problem mentioned in the background art that Liubao tea leaves rely on manual turning during the fermentation process.

[0005] To achieve the above objectives, this utility model provides the following technical solution, including a fermentation tank and a square frame placed on top of the fermentation tank. Two movable rods are connected to the top of the square frame via a horizontal moving assembly. Each of the two movable rods has a groove between them. A movable strip is connected to the groove via a lifting assembly. The surface of the movable strip slides in cooperation with the groove. Two positioning plates are fixedly connected to the bottom of the movable strip. A cylinder is rotatably connected between the two positioning plates. A first motor is mounted on one side of one of the positioning plates via a motor mount. The first motor is located inside the cylinder. The output shaft of the first motor is rotatably connected to the other positioning plate. The surface of the first motor's output shaft is fixedly connected to the inner wall of the cylinder. A flipping rod is provided on the surface of the cylinder.

[0006] Preferably, the lifting assembly includes a first threaded rod, the upper and lower sides of which are rotatably connected to the groove, the surfaces of the two opposing first threaded rods are threadedly connected to the movable rod, the top of the first threaded rod extends to the outside of the groove, a fixed plate is fixedly connected to the top of the movable rod, a second motor is provided on one of the fixed plates, the output shaft of the second motor is connected to the corresponding first threaded rod, and the second motor is connected to the other first threaded rod through a transmission assembly, the top of the other first threaded rod is rotatably connected to the corresponding fixed plate.

[0007] Preferably, the transmission assembly includes a driving wheel and a driven wheel, which are connected to each other by a belt. The inner cavity of the driving wheel is fixedly connected to the output shaft of the second motor, and the inner cavity of the driven wheel is fixedly connected to the corresponding first threaded rod.

[0008] Preferably, positioning strips are fixedly connected to the front, back, and right sides of the frame, and the positioning strips are in contact with the fermentation tank.

[0009] Preferably, the lateral movement assembly includes a second threaded rod, and grooves are provided on both the front and rear sides of the top of the frame. The two sides of the second threaded rod are rotatably connected to the grooves. The surface of the movable rod is slidably engaged with the grooves. A threaded hole is provided on the movable rod, and the inner cavity of the threaded hole is threadedly connected to the second threaded rod. The left side of the second threaded rod extends to the outside of the groove, and a turbine is fixedly connected to the surface of the second threaded rod.

[0010] Preferably, limit grooves are provided on both the front and rear sides of the slide groove, and limit blocks are fixedly connected to the bottom of both the front and rear sides of the movable rod, with the limit blocks slidingly engaging with the limit grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This solution involves placing a square frame on the fermentation tank, then starting the first motor. The output shaft of the first motor drives the cylinder to rotate, which in turn drives the turning rods on the surface to rotate. As the turning rods rotate, they move to one side of the top of the fermentation tank via a lateral moving component. Then, they enter the fermentation tank via a lifting component to turn the tea leaves inside. While turning the tea leaves, the lateral moving component moves within the fermentation tank to turn the tea leaves in other areas, eliminating the need for manual turning and thus solving the problem of relying on manual turning during the fermentation process of Liubao tea.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1:

[0023] Please see Figure 1-6 This utility model provides a technical solution: a Liubao tea fermentation tea leaf turning device, including a fermentation tank and a square frame 1 placed on top of the fermentation tank. The top of the square frame 1 is connected to two movable rods 2 through a horizontal moving component. Each of the two movable rods 2 has a groove between them. A movable strip 3 is connected to the groove through a lifting component. The surface of the movable strip 3 slides in the groove. Two positioning plates 4 are fixedly connected to the bottom of the movable strip 3. A cylinder 5 is rotatably connected between the two positioning plates 4. A first motor 6 is mounted on one side of one of the positioning plates 4 through a motor mount. The first motor 6 is located in the inner cavity of the cylinder 5. The output shaft of the first motor 6 is rotatably connected to the other positioning plate 4. The surface of the output shaft of the first motor 6 is fixedly connected to the inner wall of the cylinder 5. A turning rod 7 is provided on the surface of the cylinder 5.

[0024] Analysis of the above: When the Liubao tea leaves in the fermentation tank need to be turned, the staff places the frame 1 on the fermentation tank, then starts the first motor 6. The output shaft of the first motor 6 drives the cylinder 5 to rotate, and the cylinder 5 drives the turning rod 7 on the surface to rotate. Then, the horizontal moving component is activated to move the movable rod 2. The movable rod 2 moves the turning rod 7 to one side of the top of the fermentation tank (the far left / far right). The staff then activates the lifting component to move the movable bar 3 downward. The movable bar 3, through the positioning plate 4, drives the first motor 6, the cylinder 5, and the turning rod 7 downward until they enter the fermentation tank. The turning rod 7 turns the Liubao tea leaves in the fermentation tank. The first motor 6 is in the hollow part inside the cylinder 5 and is not affected by the tea leaves. While the turning rod 7 is turning, the horizontal moving component drives the movable rod 2 to slowly move to the other side, indirectly causing the turning rod 7 to turn the tea leaves in other areas of the fermentation tank until all the tea leaves in the fermentation tank have been turned. This eliminates the need for manual turning and solves the problem of relying on manual turning during the fermentation process of Liubao tea.

[0025] Example 2:

[0027] Analysis of the above content: When in use, the staff starts the second motor 10, which drives one of the first threaded rods 8 to rotate. Through the transmission component, it drives the other first threaded rod 8 to rotate in the same direction. When the two first threaded rods 8 rotate in the same direction, they can drive the flipping structure to move up and down.

[0028] Example 3:

[0029] Please see Figure 1-6 The present invention provides a technical solution based on Embodiment 1: the transmission assembly includes a driving wheel 11 and a driven wheel 12, the driving wheel 11 and the driven wheel 12 are connected to each other by a belt, the inner cavity of the driving wheel 11 is fixedly connected to the output shaft of the second motor 10, and the inner cavity of the driven wheel 12 is fixedly connected to the corresponding first threaded rod 8.

[0030] Analysis of the above content: When the output shaft of the second motor 10 drives one of the first threaded rods 8 to rotate, it also drives the driving wheel 11 to rotate. The driving wheel 11 drives the driven wheel 12 to rotate in the same direction through a belt (the belt is a toothed belt, and the driving wheel 11 and the driven wheel 12 also have teeth that match the toothed belt). The driven wheel 12 then drives the other first threaded rod 8 to rotate in the same direction.

[0031] Example 4:

[0032] Please see Figure 1-6 Based on Embodiment 1, this utility model provides a technical solution: positioning strips 13 are fixedly connected to the front and rear sides and the right side of the frame 1, and the positioning strips 13 are in contact with the fermentation tank.

[0033] Analysis of the above content: By setting positioning strips 13, when the frame 1 is placed on the fermentation tank, these positioning strips 13 can quickly lock onto the edge of the fermentation tank, ensuring that the frame 1 is accurately positioned in the horizontal direction, eliminating the need for additional adjustment or fixing steps, and allowing staff to quickly and accurately place the frame 1 in the designated position.

[0034] Example 5:

[0035] Please see Figure 1-6 This utility model provides a technical solution based on Embodiment 1: the lateral moving component includes a second threaded rod 14, and sliding grooves are provided on both the front and rear sides of the top of the frame 1.

[0036] Analysis of the above content: When making lateral movement, the staff starts the third motor 16. The output shaft of the third motor 16 drives the worm gear 15 to rotate. While the worm gear 15 is rotating, it meshes with two turbines to rotate in the same direction. Each turbine drives the corresponding second threaded rod 14 to rotate. While the second threaded rod 14 is rotating, it drives the movable rod 2 to move. The two movable rods 2 drive the relative flipping structure to move laterally.

[0037] Example 6:

[0038] Please see Figure 1-6Based on Embodiment 1, this utility model provides a technical solution: limit grooves are provided on both the front and rear sides of the slide groove, and limit blocks 17 are fixedly connected to the bottom of both the front and rear sides of the movable rod 2, and the limit blocks 17 slide in cooperation with the limit grooves.

[0039] Analysis of the above content: When the movable rod 2 moves, it drives the limiting block 17 to move in the limiting groove. The limiting groove restricts the limiting block 17 within the preset movement trajectory, preventing the movable rod 2 from deviating during movement.
