Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea drying technology, specifically to a tea drying device. Background Technology
[0002] Sun-drying is a crucial step in the tea production and processing. Its main purpose is to reduce the water content of tea cells by evaporating moisture, thereby lowering their activity and removing the semi-permeability of cell membranes. This lays a good foundation for subsequent fermentation and other processes, ensuring that the tea can ferment normally and fully, ultimately guaranteeing the quality of the tea.
[0003] The existing methods of drying tea mainly involve laying it on the ground or on boards. The tea leaves are kept in the same position for a long time, with some leaves always at the bottom and unable to get enough sunlight. This results in these leaves not getting enough drying, while the leaves at the top may be damaged by over-drying. This uneven drying leads to inconsistent moisture content in the tea leaves, making it difficult to ensure the consistency of tea quality during subsequent processing and affecting key quality indicators such as taste and aroma. Utility Model Content
[0004] To address this issue, this invention provides a tea drying device that uses a tea-turning drive component and a tea-turning power component to solve the problem of tea leaves remaining in the same position for extended periods, preventing some leaves from fully exposing themselves to sunlight.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea drying device, comprising a fixed plate, two through slots fixedly provided on the top of the fixed plate, a drying frame fixedly provided on the top of the fixed plate, a drying net fixedly provided at the bottom of the drying frame, two fixed legs fixedly provided at the bottom of the fixed plate, a base plate fixedly provided at the bottom of each of the two fixed legs, two locking casters connected to the bottom of each of the two base plates, a tea-turning drive assembly provided at the bottom of the fixed plate, a tea-turning power assembly provided on the top of the fixed plate, the tea-turning drive assembly comprising a drive unit and a driven unit, the drive unit comprising a dual-axis servo motor, a transmission shaft fixedly connected to each of the two output ends of the dual-axis servo motor, a first hanging ear sleeved on the outside of each of the two transmission shafts, the driven unit comprising a rotating shaft, two second hanging ears sleeved on the outside of the rotating shaft, two drive components connected between the transmission shaft and the rotating shaft, the tea-turning power assembly comprising two sliders, a bracket fixedly provided on the top of each of the two sliders, a motor fixedly provided on the top of the bracket, a transmission rod fixedly provided at the output end of the motor, and a tea-pushing rod fixedly provided at the bottom of the transmission rod.
[0006] Preferably, the dual-axis servo motor has a fixed plate at the bottom, and one side of the dual-axis servo motor is fixedly connected to one of the fixed legs.
[0007] Preferably, the tops of both the first and second hanging ears are fixedly connected to the bottom of the fixing plate.
[0008] Preferably, the lug is disposed outside the drive shaft and connected to the drive shaft via a bearing.
[0009] Preferably, the two hanging ears are set outside the rotating shaft and connected to the rotating shaft through bearings.
[0010] Preferably, the driving component includes a first synchronous pulley and a second synchronous pulley. The first synchronous pulley is fixedly sleeved on the outside of the transmission shaft, and the second synchronous pulley is fixedly sleeved on the outside of the rotating shaft. A synchronous belt is sleeved on the outside of the first and second synchronous pulleys. The first and second synchronous pulleys are driven and connected by the synchronous belt, and the synchronous belt is fixedly connected to the bottom of the slider.
[0011] Preferably, the slider is disposed inside the through groove and is slidably connected to the through groove.
[0012] Preferably, the transmission rod passes through the top of the bracket and is connected to the top of the bracket via a bearing.
[0013] The present invention has the following advantages:
[0014] Through the coordinated operation of the tea-turning drive component and the tea-turning power component, the dual-axis servo motor drives the support to move back and forth, and the motor drives the tea push rod to rotate, which can fully turn the tea on the drying net, allowing the upper and lower layers of tea to be fully turned. This effectively solves the problem of uneven drying caused by the tea being in the same position for a long time in traditional drying, ensuring that the moisture content of the tea is consistent and guaranteeing the stability of the tea quality in subsequent processing.
[0015] In the tea-turning drive assembly, synchronous pulley one, synchronous belt, and synchronous pulley two adopt a toothed structure for meshing transmission, which avoids slippage, ensures accurate transmission ratio, and makes the tea-turning power assembly move stably. The sliding cooperation between the slider and the through groove provides stable guidance for the tea-turning power assembly. The transmission rod and the bracket are connected by bearings to reduce rotational friction. The overall structure operates smoothly, reduces energy loss, and avoids the tea-turning effect being affected by component jamming.
[0016] The device is equipped with locking casters at the bottom. By releasing the locking mechanism, the device can be moved, making it easy to adjust the drying position according to the sunlight conditions. After moving it to a suitable position, locking the casters will ensure stable placement. It can flexibly adapt to different drying environments, thus improving the practicality of the device.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] See attached document Figure 1 - Appendix Figure 4This utility model provides a tea drying device, including a fixed plate 1, two through slots 2 fixedly provided on the top of the fixed plate 1, a drying frame 3 fixedly provided on the top of the fixed plate 1, a drying net 4 fixedly provided on the bottom of the drying frame 3, two fixed legs 5 fixedly provided on the bottom of the fixed plate 1, a base plate 6 fixedly provided on the bottom of each of the two fixed legs 5, and two locking casters 7 connected to the bottom of each of the two base plates 6, a tea-turning drive assembly provided on the bottom of the fixed plate 1, and a tea-turning power assembly provided on the top of the fixed plate 1. The tea-turning drive assembly includes a drive unit and a driven unit. The drive unit includes... The system includes a dual-axis servo motor 8, with a drive shaft 9 fixedly connected to each of the two output ends of the dual-axis servo motor 8. Each of the two drive shafts 9 is fitted with a first hook 10. The driven unit includes a rotating shaft 14, with two second hooks 15 fitted to the outside of the rotating shaft 14. Two drive components are connected between the drive shaft 9 and the rotating shaft 14. The tea-twisting power assembly includes two sliders 16, with a bracket 17 fixedly mounted on the top of the two sliders 16. A motor 18 is fixedly mounted on the top of the bracket 17. A drive rod 19 is fixedly mounted on the output end of the motor 18. A tea-pushing rod 20 is fixedly mounted on the bottom of the drive rod 19.
[0026] In this implementation scheme, in order to achieve the purpose of automatic turning of tea leaves during the drying process, the dual-axis servo motor 8 is started, and its output end drives the transmission shaft 9 to rotate. Since the transmission shaft 9 is connected to the hanging lug 10 fixed at the bottom of the fixed plate 1 through the bearing, it can rotate stably. The dual-axis servo motor 8 can rotate in both directions, so that the bracket 17 can move back and forth on the top of the fixed plate 1. The rotation of the transmission shaft 9 drives the synchronous wheel 11 to rotate. Through the synchronous belt 12, the synchronous wheel 13 and the rotating shaft 14 rotate accordingly. The synchronous belt 12 drives the slider 16 to slide in the through groove 2, thereby causing the bracket 17 and the motor 18, transmission rod 19 and tea push rod 20 above it to move back and forth above the drying frame 3. At the same time, the motor 18 is started, and the transmission rod 19 drives the tea push rod 20 to rotate. Since the tea push rod 20 is in contact with the drying net 4, it can spread the tea leaves evenly, so that the upper and lower layers of tea leaves can be fully turned over, avoiding uneven drying.
[0027] To achieve a stable and directional driving force for the tea-tumbling power component, ensuring its precise and smooth reciprocating movement along the fixed plate, the device employs the following technical solution: A dual-axis servo motor 8 is mounted on the bottom of the fixed plate 1. One side of the dual-axis servo motor 8 is fixedly connected to one of the fixed legs 5. The tops of both the first hanging ear 10 and the second hanging ear 15 are fixedly connected to the bottom of the fixed plate 1. The first hanging ear 10 is fitted onto the outside of the drive shaft 9 and connected to the drive shaft 9 via a bearing. The second hanging ear 15 is fitted onto the outside of the rotating shaft 14 and connected to the rotating shaft 14 via a bearing. The driving component includes a synchronous pulley 11. Synchronous pulley 11 and synchronous pulley 2 13 are fixedly sleeved on the outside of the drive shaft 9, and synchronous pulley 2 13 is fixedly sleeved on the outside of the rotating shaft 14. A synchronous belt 12 is sleeved on the outside of synchronous pulley 11 and synchronous pulley 2 13. Synchronous pulley 11 and synchronous pulley 2 13 are driven connected by synchronous belt 12. Synchronous belt 12 is fixedly connected to the bottom of slider 16. When the dual-axis servo motor 8 is started, its two output ends drive the drive shaft 9 to rotate. Since the drive shaft 9 is connected to the lug 1 10 through bearings, and the lug 1 10 is fixed to the bottom of the fixed plate 1, the drive shaft 9 can rotate stably, and the synchronous pulley 11 fixedly sleeved on its outside rotates accordingly. Under the transmission action of the synchronous belt 12, the second synchronous pulley 13 rotates, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 is connected to the second hanging lug 15 through the bearing, and can also rotate smoothly. When the synchronous belt 12 moves, it will drive the slider 16 fixedly connected to it to slide in the through groove 2. Regarding the transmission of the first synchronous pulley 11, the synchronous belt 12, and the second synchronous pulley 13: all three adopt a toothed structure design. The outer circumference of the first synchronous pulley 11 and the second synchronous pulley 13 are provided with evenly distributed teeth, and the inner side of the synchronous belt 12 is provided with corresponding tooth grooves that match the teeth. When the dual-axis servo motor 8 drives the transmission shaft 9 to rotate, the transmission... Shaft 9 drives synchronous pulley 11 to rotate synchronously. The teeth on synchronous pulley 11 mesh with the tooth grooves on the inner side of synchronous belt 12, thereby driving synchronous belt 12 to transmit power. Under the drive of synchronous belt 12, synchronous pulley 13, which meshes with it through the teeth, also rotates, realizing the transmission of power from drive shaft 9 to rotating shaft 14. This tooth meshing transmission method can effectively avoid slippage during transmission, ensure the accuracy of transmission ratio, and enable synchronous belt 12 to stably drive slider 16 to move, thereby ensuring the movement accuracy of the tea-turning power component and providing a reliable guarantee for the uniform turning of tea leaves.
[0028] To ensure the stability and guidance of the tea-turning power component during movement, the device employs the following technical solution: A slider 16 is located inside the through groove 2 and slidably connected to it; a transmission rod 19 passes through the top of the bracket 17 and is connected to the top of the bracket 17 via a bearing. The sliding cooperation between the slider 16 and the through groove 2 precisely limits the direction of movement of the tea-turning power component, preventing it from deviating or wobbling during movement with the synchronous belt 12. This allows the tea-turning power component to move smoothly along a fixed trajectory, ensuring that the tea pusher evenly covers the tea area within the drying frame 3. The connection between the transmission rod 19 and the top of the bracket 17 via a bearing significantly reduces friction during rotation, making the rotation of the transmission rod 19 and tea pusher 20 by the motor 18 smoother, reducing energy loss due to running resistance, and preventing excessive squeezing or uneven turning of the tea by the tea pusher 20 due to jamming.
[0029] The usage process of this utility model is as follows: When using this utility model, connect an external power source and evenly spread the tea leaves to be dried on the drying mesh 4 inside the drying frame 3. At this time, the tea push rod 20 is in contact with the top of the drying mesh 4. This contact provides the basis for subsequent turning of the tea leaves. To turn the tea leaves, start the dual-axis servo motor 8. Its two output ends drive the transmission shaft 9 to rotate. Since the transmission shaft 9 is connected to the hanging ear 10 through bearings, and the hanging ear 10 is fixed to the bottom of the fixing plate 1, the transmission shaft 9 can rotate stably. It is worth noting that the dual-axis servo motor 8 can... The ability to rotate in both directions allows the subsequent support 17 to move back and forth on the top of the fixed plate 1. When the drive shaft rotates, the externally fixed synchronous wheel 11 rotates accordingly. Under the transmission action of the synchronous belt 12, the synchronous wheel 13 rotates as well, thereby driving the rotating shaft 14 to rotate. The rotating shaft 14 is connected to the hanging lug 15 through the bearing, and can also rotate smoothly. When the synchronous belt 12 moves, it will drive the slider 16 fixedly connected to it to slide in the through groove 2. When the dual-axis servo motor 8 rotates forward, the synchronous belt 12 drives the slider 16 to slide in one direction along the through groove 2; when the dual-axis servo motor 8 rotates backward, the synchronous belt 12 drives the slider 16 to slide in one direction along the through groove 2; when the dual-axis servo motor 8 rotates forward, the synchronous belt 12 drives the slider 16 to slide in one direction along the through groove 2. When reversing, the synchronous belt 12 drives the slider 16 to slide in the opposite direction along the through groove 2. As a result, the bracket 17 at the top of the slider 16 moves back and forth on the top of the fixed plate 1 along with the slider 16. The motor 18, transmission rod 19, and tea pusher 20 on the bracket 17 also move back and forth above the drying frame 3. Simultaneously, the motor 18 is started, and its output drives the transmission rod 19 to rotate. The tea pusher 20 at the bottom of the transmission rod 19 then begins to rotate. As the tea pusher 20 rotates and moves back and forth with the bracket 17, it contacts the top of the drying mesh 4, causing the rotating tea pusher... The push rod 20 will thoroughly turn over the tea leaves on the drying net 4. Whether the tea leaves are at the top or at the bottom, they will be fully turned over by the tea push rod 20. Tea leaves that were originally at the bottom and could not get enough sunlight can be turned to the top, which effectively avoids the problem of uneven drying caused by the tea leaves being in the same position for a long time. When it is necessary to move the entire device, release the locking structure of the locking caster 7 and push the device to move it on the ground. After moving it to a sunny position, lock the locking caster 7, and the device will be placed stably, ensuring that the tea leaves are dried in a suitable environment.

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
