Description

Technical Field

[0001] The present invention relates to the field of tea production, and in particular to a uniform feeding device for tea pile fermentation, and also relates to a piling method. Background Art

[0002] Tea pile fermentation is a key process in the production of post-fermented teas such as dark tea and Pu-erh tea. This process plays a decisive role in the quality, taste, aroma, color and other characteristics of tea. During the pile fermentation process, under the action of suitable temperature, humidity and microorganisms, a series of complex biochemical reactions occur in the tea, such as the oxidation and polymerization of polyphenols, the transformation of amino acids, the decomposition of sugars, etc., thus forming the unique flavor and quality characteristics of dark tea and Pu-erh tea. Therefore, ensuring the uniformity and stability of the tea pile fermentation process is crucial for improving the quality of tea products and market competitiveness.

[0003] The patent with the publication number CN117121957B discloses an integrated infrared-sensing tea height-fixed pile robot and its piling method. During piling, the piling motor drives the worm to rotate, the rotating worm drives the worm gear and the lead screw to rotate, the worm gear drives the regular triangular gear ring to rotate counterclockwise through the transmission shaft, and then drives the reverse triangular gear ring and the driving pulley to rotate counterclockwise. The driving pulley drives the fifth roller to rotate through the transmission belt, so that the lifting belt operates, conveys the tea discharged from the tea outlet upward to the upper part of the round barrel, and drops into the round barrel. The tea dropped into the round barrel enters the conical barrel, and finally enters the spinal canal surrounded by the combination of arc cone pieces, and is discharged from the lower port of the spinal canal and drops to the ground to form a tea cone pile. The lead screw drives the threaded sleeve to lift upward, and then drives the lifting platform, the round barrel, and the conical barrel to slowly lift. Since the arc cone piece group is restricted by the slide rod and the sliding sleeve, the height of the arc cone piece group is always the same as the height of the hoop, and the distance between the arc cone piece group and the outer wall of the conical barrel is constant. Therefore, when the conical barrel is lifted, the arc cone piece group will gather together, causing the lower port of the arc cone piece group to contract, that is, the lower port diameter of the stacking mechanism continuously decreases, realizing that as the pile height increases, the discharge diameter of the tea continuously decreases, increasing the taper of the pile and reducing the cone diameter of the cone pile, which is beneficial to the heating or heat dissipation fermentation of the tea inside the cone pile.

[0004] Although the above scheme reduces the cone diameter of the cone pile through a mechanized scheme, making it easier for the tea leaves to ferment inside, the amount of tea leaves continuously transported into the vertebral canal surrounded by the arc cone piece combination is not fixed. When the amount of tea leaves continuously transported is large, the tea leaves can fill the lower end opening of the vertebral canal surrounded by the arc cone piece combination, so that the tea leaves can fall evenly from the lower end opening of the vertebral canal surrounded by the arc cone piece combination. However, when the amount of tea leaves transported in part during the continuous transportation process is small, the tea leaves cannot fill the lower end opening of the vertebral canal surrounded by the arc cone piece combination, and the tea leaves may fall directly from the lower end opening of the vertebral canal surrounded by the arc cone piece combination. The vertebral canal surrounded by the arc cone piece combination cannot control the falling position of the tea leaves, and at this time the tea leaves may fall to the middle of the tea pile that deviates from the initial formation. Summary of the invention

[0020] S5. The tea leaves are stacked at the lower end of the feeding cylinder.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. The present invention is provided with a temporary storage mechanism and a feeding mechanism. The storage cylinder in the temporary storage mechanism and the feeding cylinder in the feeding mechanism are arranged vertically and coaxially and communicate with each other, constituting a moving channel for the tea leaves, providing a clear and stable flow path for the tea leaves, enabling the tea leaves to be transported in a predetermined direction, avoiding the scattering and chaos of the tea leaves during the transportation process, ensuring the orderly flow of the tea leaves. The paving mechanism is arranged in the storage cylinder to evenly spread the tea leaves entering the storage cylinder in the storage cylinder. During the continuous entry of the tea leaves into the storage cylinder, the paving mechanism always remains in a working state to ensure the uniform distribution of the tea leaves in the storage cylinder, avoiding the situation of accumulation or vacancy of the tea leaves in the storage cylinder. The multiple partition structures in the feeding mechanism work synchronously under the control of the control mechanism, ensuring that the opening degrees at various places are the same when the moving channel is opened, so that the flow rates of the tea leaves at various places in the moving channel are the same, thereby ensuring that when the tea leaves finally fall out of the feeding cylinder, they can evenly fall on the tea leaf pile formed by the initial wet-piling, avoiding the tea leaves falling on a local area of the tea leaf pile formed by the initial wet-piling.

[0023] 2. The present invention is provided with multiple paving components, a first synchronization component and a first rotation driving component. The multiple paving components are arranged equidistantly around the axis of the storage cylinder inside the storage cylinder, enabling the paving components to cover a large range inside the storage cylinder. When the tea leaves enter the storage cylinder, the paving components can act on the tea leaves at different positions, avoiding the situation where the tea leaves accumulate in a local area of the storage cylinder and cannot be effectively paved. The second synchronization component drives all the paving components to rotate around the axis of the storage cylinder simultaneously, ensuring the movement synchronization between the various paving components, thereby realizing the uniform distribution of the tea leaves in the storage cylinder and making the tea leaf pile temporarily stored in the storage cylinder in a cylindrical shape.

[0024] 3. The present invention is provided with a partition board and an opening and closing component. One end of the partition board is pivotally connected to the inner top of the feeding cylinder. When the multiple partition boards are coplanar, they can form a complete circle to separate the feeding cylinder and the storage cylinder. Before the tea leaves enter the storage cylinder, the opening and closing component can drive the partition board to rotate to a horizontal state to separate the connection between the storage cylinder and the feeding cylinder to prevent the leakage of the tea leaves. According to the requirements of different stages of the tea leaf wet-piling, the opening and closing component can control the partition board to rotate to different inclination angles to change the diameter of the channel formed between the multiple partition boards. When a larger diameter is required to form a stable tea leaf pile at the initial stage of the tea leaf wet-piling, the partition board is rotated to the maximum inclination angle to form a channel with the maximum diameter, so that the falling coverage range of the tea leaves is the largest. As the height of the tea leaf pile increases and the diameter decreases, the inclination angle of the partition board is gradually reduced, so that the channel diameter decreases accordingly, thereby realizing that the tea leaves fall on the tea leaf pile from a position closer to the middle of the tea leaf pile.

Detailed implementation manners

[0036] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0037] Refer to Figures 1 to 10 As shown in the figure: A uniform feeding device for tea pile fermentation includes a temporary storage mechanism 1 and a feeding mechanism 2 arranged vertically one above the other; the temporary storage mechanism 1 includes a storage cylinder 11 for temporarily storing tea and a flattening mechanism 12 arranged in the storage cylinder 11. The axis of the storage cylinder 11 is vertically arranged, and the flattening mechanism 12 is used to evenly spread the tea entering the storage cylinder 11 in the storage cylinder 11; the feeding mechanism 2 includes a feeding cylinder 21 communicated with the lower end of the storage cylinder 11 and a control mechanism 23, and the feeding cylinder 21 is coaxially arranged with the storage cylinder 11. A plurality of partition structures 22 are arranged at the inner top of the feeding cylinder 21. The plurality of partition structures 22 are arranged at equal intervals around the axis of the feeding cylinder 21, and the plurality of partition structures 22 are used to control the communication state between the storage cylinder 11 and the feeding cylinder 21. The control mechanism 23 is connected to the plurality of partition structures 22, and the control mechanism 23 is used to drive the plurality of partition structures 22 to work simultaneously.

[0038] Before the discharge device is put into operation, the temporary storage mechanism 1 and the discharge mechanism 2 need to be adjusted to a vertical position. At this time, the storage cylinder 11 in the temporary storage mechanism 1 and the discharge cylinder 21 in the discharge mechanism 2 are connected to each other to form a moving channel for the tea leaves. Subsequently, the control mechanism 23 drives the multiple partition structures 22 to move synchronously. The multiple partition structures 22 separate the connection between the storage cylinder 11 and the discharge cylinder 21, so that the moving channel for the tea leaves is in a closed state. When the tea leaves are continuously transported into the storage cylinder 11, the tea leaves will be blocked by the multiple partition structures 22 and stay in the storage cylinder 11. In the process of the tea leaves continuously entering the storage cylinder 11, the spreading mechanism 12 always keeps working to spread the tea leaves evenly in the storage cylinder 11. The barrel 11 has the function of temporarily storing tea leaves. When the height of the tea leaves in the storage barrel 11 reaches a preset value, the tea leaves in the storage barrel 11 need to be discharged. At this time, the control mechanism 23 controls the multiple partition structures 22 to open the moving channel for the tea leaves. The tea leaves in the storage barrel 11 flow into the discharge barrel 21 under the action of gravity, and are finally stacked at the lower end of the discharge barrel 21. The tea leaves are spread flat in the storage barrel 11 by the spreading mechanism 12. The tea leaves are temporarily stored in the storage barrel 11 in a cylindrical shape. When the tea leaves fall from the storage barrel 11, the flow rate of the tea leaves at various places in the moving channel is the same, thereby ensuring that when the tea leaves finally fall out of the discharge barrel 21, they can evenly fall on the tea leaves pile formed by the preliminary fermentation, and avoid the tea leaves falling on the local area of ​​the tea leaves pile formed by the preliminary fermentation.

[0039] Reference Figure 3 and Figure 4 As shown: the paving mechanism 12 includes a plurality of paving components 121, a first synchronous component 122 and a first rotating drive component 123; the plurality of paving components 121 are arranged at equal intervals inside the storage tube 11 around the axis of the storage tube 11; the first synchronous component 122 is connected to the plurality of paving components 121; the first rotating drive component 123 is transmission-connected to the first synchronous component 122.

[0040] Specifically, the paving assembly 121 includes a vertical rod 1211 that is tightly attached to the inner wall of the storage barrel 11, and the vertical rod 1211 is parallel to the axis of the storage barrel 11, and a plurality of paving rods 1212 extending to the middle of the storage barrel 11 are arranged on the vertical rod 1211, and the first synchronization assembly 123 includes a first annular seat 1221 coaxially arranged at the upper end of the storage barrel 11, and a first annular plate 1222 that can rotate around the axis of the first annular seat 1221 is arranged on the first annular seat 1221, and the first annular plate 1222 is connected to the vertical rods 1211 in the plurality of paving assemblies 121, and the first rotation drive assembly 123 includes a first outer gear ring 1231 coaxially connected to the first annular plate 1222, a first rotation driver 1232 is arranged on one side of the first outer gear ring 1231, and a first gear 1233 meshing with the first outer gear ring 1231 is arranged at the output end of the first rotation driver 1232.

[0041] There are various ways to drive the tea leaves to be laid flat in the storage cylinder 11. In this solution, the method of rotating and stirring is adopted to evenly spread the tea leaves in the storage cylinder 11. During the process of the tea leaves entering the storage cylinder 11, the first rotation drive assembly 123 is started. The first rotation driver 1232 in the first rotation drive assembly 123 drives the first gear 1233 to rotate. The first gear 1233 drives the first outer gear ring 1231 meshing with it to rotate. The first outer gear ring 1231 drives the first annular plate 1222 to rotate around the axis of the storage cylinder 11. The first annular plate 1222 drives a plurality of spreading components 121 to rotate around the axis of the storage cylinder 11. The vertical rod 1211 in the spreading component 121 drives a plurality of spreading rods 1212 to rotate around the axis of the storage cylinder 11. Since the spreading rods 1212 extend to the middle of the storage cylinder 11, the internal range of the storage cylinder 11 can be completely covered by the spreading rods 1212. When the tea leaves fall on one side of the storage cylinder 11 that is off-center, a plurality of spreading components 121 can drive the tea leaves to move, so as to realize the uniform distribution of the tea leaves in the storage cylinder 11, and make the tea leaf pile temporarily stored in the storage cylinder 11 in a cylindrical shape.

[0042] Refer to Figure 3 and Figure 5 As shown: The partition structure 22 includes a partition board 221 and an opening and closing component 222; one end of the partition board 221 is connected to the inner top of the feeding cylinder 21. When a plurality of partition boards 221 are coplanar, the plurality of partition boards 221 form a complete circle and partition the feeding cylinder 21 and the storage cylinder 11; the opening and closing component 222 is used to drive the partition board 221 to rotate around the axis connection of the partition board 221 and the feeding cylinder 21.

[0043] Before the tea leaves enter the storage cylinder 11, the opening and closing component 222 controls the partition board 221 to rotate around the connection of the partition board 221 and the feeding cylinder 21, so that the partition board 221 rotates to the horizontal state. At this time, all the partition boards 221 are in the horizontal state, so that all the partition boards 221 form a complete circle and partition the connection between the storage cylinder 11 and the feeding cylinder 21. During the process of the spreading mechanism 12 spreading the tea leaves in the storage cylinder 11, all the partition boards 221 remain in the horizontal state to ensure that the tea leaves will not leak from the storage cylinder 11. When it is necessary to discharge the tea leaves in the storage cylinder 11, at the initial stage of the tea leaf piling up, since a larger diameter is required to form a stable tea leaf pile, at this time the opening and closing component 222 rotates the partition board 221 to the maximum inclination angle, so that a plurality of partition boards 221 form a channel with the largest diameter, and the coverage range of the tea leaves after falling is the largest. As the height of the tea leaf pile increases, the diameter of the tea leaf pile will gradually decrease. During this process, the opening and closing component 222 controls the inclination angle of the partition board 221 to gradually decrease, so that the diameter of the channel formed between a plurality of partition boards 221 gradually decreases, so as to realize that the tea leaves fall on the tea leaf pile from a position closer to the middle of the tea leaf pile.

[0044] Refer to Figure 3 、 Figure 5 and Figure 6 As shown, the opening and closing assembly 222 includes a moving block 2221 that can move along the axis of the material discharging cylinder 21 while closely adhering to the outer wall of the material discharging cylinder 21, a transmission rod 2222, and a first spring 2223 sleeved on the transmission rod 2222; one end of the transmission rod 2222 vertically passes through the moving block 2221 and is pivotally connected to the partition plate 221; both ends of the first spring 2223 are respectively connected to the end of the transmission rod 2222 and the moving block 2221.

[0045] In the initial state, multiple partition plates 221 in the material discharging mechanism 2 all maintain a horizontal position, jointly forming a circular closed surface for closing the lower end of the storage cylinder 11. At this time, the first spring 2223 sleeved on one end of the transmission rod 2222 is in a compressed state. When it is necessary to release the tea leaves, multiple opening and closing assemblies 222 are started synchronously. The moving block 2221 moves downward along the outer wall of the material discharging cylinder 21 and is transmitted to the partition plate 221 through the transmission rod 2222. As the moving block 2221 moves, the partition plate 221 rotates around its connection with the material discharging cylinder 21, and the end of the transmission rod 2222 connected to the partition plate 221 moves towards the moving block 2221. During this process, the first spring 2223 gradually releases the elastic potential energy it stores, providing additional assistance for the movement of the transmission rod 2222. Since all the opening and closing assemblies 222 work synchronously, all the partition plates 221 in the first partition structure 22 and the second partition structure 22 open in a funnel shape. When it is necessary to close the lower end of the storage cylinder 11, the moving block 2221 moves upward along the outer wall of the material discharging cylinder 21. The moving block 2221 simultaneously drives the transmission rod 2222 to move horizontally upward, causing the transmission rod 2222 to move towards the inside of the material discharging cylinder 21. The first spring 2223 is gradually compressed. When the partition plate 221 rotates to the horizontal state, the moving block 2221 stops moving, thereby realizing the control of the opening and closing of the tea leaf flow channel.

[0046] Refer to Figure 3 and Figure 7 As shown, the control mechanism 23 includes multiple driving arm assemblies 231, a second synchronization assembly 232, and a second rotation driving assembly 233; multiple driving arm assemblies 231 are respectively connected to multiple partition structures 22, and multiple driving arm assemblies 231 respectively drive multiple partition structures 22 to move; the second synchronization assembly 232 is connected to multiple driving arm assemblies 231; the second rotation driving assembly 233 is in transmission connection with the second synchronization assembly 232.

[0047] Specifically, the second rotation drive assembly 233 includes a second external gear ring 2331 coaxially arranged with the material discharging cylinder 21. The second external gear ring 2331 is connected to the second synchronization assembly 232. A second rotation driver 2332 is arranged on one side of the second external gear ring 2331. A second gear 2333 is arranged at the output end of the second rotation driver 2332. The second gear 2333 meshes with the second external gear ring 2331.

[0048] When it is necessary to perform a closing operation on the lower end of the storage cylinder 11, the second rotation driver 2332 in the second rotation drive assembly 233 is started to drive the second gear 2333 to rotate. The rotation of the second gear 2333 drives the second external gear ring 2331 engaged therewith to rotate around the axis of the material discharging cylinder 21. The second external gear ring 2331 converts the rotational motion into a force through the second synchronization assembly 232 and transmits it to the plurality of drive arm assemblies 231. The drive arm assemblies 231 apply an upward force along the material discharging cylinder 21 to the moving block 2221 in the opening and closing assembly 222, prompting the moving block 2221 to move upward, thereby achieving the purpose of closing the lower end of the storage cylinder 11. When it is necessary to connect the storage cylinder 11 and the material discharging cylinder 21, the second rotation driver 2332 drives the second gear 2333 to rotate in the reverse direction. The second gear 2333 applies a reverse force to the plurality of drive arm assemblies 231 through the second external gear ring 2331 and the second synchronization assembly 232. After the drive arm assemblies 231 receive the reverse force, they apply a downward force along the material discharging cylinder 21 to the moving block 2221 in the opening and closing assembly 222, causing the moving block 2221 to move downward, realizing the opening of the lower end of the storage cylinder 11, and thus realizing the function of synchronously controlling the movement of the plurality of partition structures 22.

[0049] Refer to Figure 7 and Figure 8 As shown: The drive arm assembly 231 includes a fixed seat 2311 arranged at the top of the material discharging cylinder 21. A telescopic rod 2312 is movably arranged in the fixed seat 2311. A linear drive plate 2313 is arranged at one end of the telescopic rod 2312. The two ends of the linear drive plate 2313 are respectively pivotally connected to the telescopic rod 2312 and the moving block 2221. A transmission column 2314 is arranged at the other end of the telescopic rod 2312. The transmission column 2314 is connected to the second synchronization assembly 232.

[0050] In the initial state, that is, when all the partition plates 221 are horizontal, the transmission column 2314 is located at one end far from the center of the feeding cylinder 21. When it is necessary to drive the partition plate 221 to open, the second synchronization component 232 drives the transmission column 2314 to move along the fixed seat 2311 towards the center direction of the feeding cylinder 21. During this process, the telescopic rod 2312 slides in the fixed seat 2311 due to the driving action of the transmission column 2314, and the end of the telescopic rod 2312 connected to the linear driving plate 2313 pulls the linear driving plate 2313 to move. The force received by the linear driving plate 2313 is transmitted to the moving block 2221 through the shaft joint. This force is decomposed into two component forces, namely the first component force vertically downward and the second component force perpendicular to the axis of the feeding cylinder 21. The vertically downward first component force pushes the moving block 2221 to move downward along the outer wall of the feeding cylinder 21. The moving block 2221 drives the partition plate 221 to move during the movement. By controlling the moving distance of the transmission column 2314, the opening and closing angle of the partition plate 221 can be controlled.

[0051] Refer to Figure 7 and Figure 9 As shown in: The second synchronization component 232 includes a second annular seat 2321 coaxially arranged with the feeding cylinder 21. A second annular plate 2322 capable of rotating around the axis of the second annular seat 2321 is arranged on the second annular seat 2321. A plurality of arc-shaped driving plates 2323 are arranged on the second annular plate 2322. The inner arc surfaces of the plurality of arc-shaped driving plates 2323 are tangent to the outer peripheral surface of the transmission column 2314.

[0052] When the second external gear ring 2331 drives the second annular plate 2322 to rotate around the axis of the feeding cylinder 21, the second annular plate 2322 drives all the arc-shaped driving plates 2323 to rotate synchronously. As the arc-shaped driving plates 2323 rotate around the axis of the feeding cylinder 21, the transmission column 2314 tangent to the inner arc surface of the arc-shaped driving plate 2323 will be pushed by the arc-shaped driving plate 2323, and the transmission column 2314 moves towards the middle of the feeding cylinder 21. During this process, since the plurality of arc-shaped driving plates 2323 are respectively tangent to the plurality of transmission columns 2314, the synchronous movement of all the transmission columns 2314 is realized.

[0053] Refer to Figure 7 and Figure 10 As shown in: The driving arm assembly 231 further includes a transmission wheel 2315. The transmission wheel 2315 is arranged on the transmission column 2314, and the transmission wheel 2315 is tangent to the inner arc surface of the arc-shaped driving plate 2323.

[0054] The arc-shaped driving plate 2323 uses its inner arc surface to push the transmission column 2314 to move linearly along the axis direction of the telescopic rod 2312. The direct contact between the inner arc surface of the arc-shaped driving plate 2323 and the transmission column 2314 will cause different degrees of wear on both of them under long-term friction. This wear will gradually change the effect of the arc-shaped driving plate 2323 on the transmission column 2314, and may further cause the problem of asynchronization of the movement time of the transmission column 2314. Therefore, a transmission wheel 2315 is arranged on the transmission column 2314. The transmission wheel 2315 is in close contact with the inner arc surface of the arc-shaped driving plate 2323 and remains in a tangent state. During the rotation of the arc-shaped driving plate 2323, the transmission wheel 2315 can not only move along the inner arc surface of the arc-shaped driving plate 2323, but also rotate itself, converting the original sliding friction into rolling friction, reducing the friction loss of the arc-shaped driving plate 2323, thereby avoiding the problem of deformation of the arc-shaped driving plate 2323 caused by wear, and effectively preventing the asynchronous movement of the transmission rod 2222.

[0055] Refer to Figure 8 As shown in the figure: The opening and closing assembly 222 further includes at least two guide rods 2224 respectively arranged on both sides of the moving block 2221. A slider 2225 is sleeved on each guide rod 2224. The slider 2225 is connected to the moving block 2221. A second spring 2226 is sleeved on each guide rod 2224. The two ends of the second spring 2226 are respectively in contact with the end of the guide rod 2224 and the slider 2225.

[0056] When the arc-shaped driving plate 2323 rotates around the feeding cylinder 21, the arc-shaped driving plate 2323 will apply a force towards the middle of the feeding cylinder 21 to the transmission column 2314. When the arc-shaped driving plate 2323 rotates in the reverse direction around the feeding cylinder 21, the arc-shaped driving plate 2323 cannot apply a force towards the outside of the feeding cylinder 21 to the transmission column 2314, resulting in the transmission column 2314 being unable to reset, and further unable to drive the partition plate 221 to reset. By sleeving second springs 2226 on both guide rods 2224, during the process of the arc-shaped driving plate 2323 applying a thrust to the transmission column 2314, the moving block 2221 drives the two sliders 2225 to respectively squeeze the two second springs 2226. The two second springs 2226 are compressed and store elastic potential energy. When the arc-shaped driving plate 2323 rotates in the reverse direction around the baffle cylinder, the two second springs 2226 release the elastic potential energy. The two second springs 2226 push the moving block 2221 to reset. The moving block 2221 drives the partition plate 221 to reset through the transmission rod 2222, thereby realizing the automatic reset of a plurality of partition plates 221.
