[0004] However, in the use of the above-mentioned fermentation tank, it is necessary to use a turning rod to turn the tea leaves in the feeding tray to ensure that the tea leaves are heated and moistened evenly during fermentation. However, using the turning rod to turn the tea leaves can easily damage or break them, which is not conducive to the integrity of the tea leaves during fermentation and thus cannot guarantee the quality of the tea fermentation. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that it is necessary to set a turning rod to turn the tea leaves in the feeding tray to ensure that the tea leaves are heated and moistened evenly during fermentation.

A movable pressure plate is fixedly installed on the left end of the lifting nozzle pipe. The movable pressure plate is fixedly installed through the sleeve plate from bottom to top and slidably installed through the upper end of the fermentation box. It also includes a leak-proof mechanism to prevent tea leaves from leaking out of the top of the storage bucket when the tea leaves are stirred up. The leak-proof mechanism includes baffles symmetrically arranged on the left and right sides of the top of the storage bucket. At least three blocking strips are fixedly installed on the lower end of each baffle. The lower end of each baffle is slidably installed on a sleeve plate. A spring is fixedly installed on the opposite ends of each baffle. The opposite ends of each spring are fixedly connected to the sleeve plate.

[0007] Preferably, an airbag is fixedly installed at the upper end of the fermentation tank, and the upper end of the airbag is fixedly installed on a movable pressure plate. The movable pressure plate has a channel inside for communication between the airbag and the lifting nozzle pipe and the anti-stacking nozzle pipe.

[0008] Preferably, at least ten push blocks are slidably installed at equal intervals along the lower edge of the storage bin, with the upper ends of the push blocks inclined towards the center of the storage bin.

[0009] Preferably, each pusher block has a wedge fixedly installed at its lower end, and a top block is fixedly installed at the upper end of the anti-stacking nozzle pipe corresponding to the wedge.

[0010] Preferably, a material box is fixedly installed at the upper end of the fermentation box, and a discharge port is opened at the upper end of the fermentation box corresponding to the outlet of the material box. A sealing plate is slidably installed at the lower end of the discharge port.

[0011] Preferably, a guide rod is fixedly installed at the rear end of the sealing plate, and an eccentric wheel is abutted and fitted at the rear end of the guide rod, with the eccentric wheel fixedly connected to the motor output shaft.

[0012] Preferably, a vertical plate is slidably installed through the rear end of the guide rod, the upper end of the vertical plate is fixedly installed on the top of the fermentation box, and a spring is sleeved on the outer side of the guide rod, with the two ends of the spring being fixedly connected to the sealing plate and the vertical plate respectively.

[0013] Preferably, each of the baffles is fixedly installed with a magnetic stripe 1, the magnetic stripe 1 on the left side is movably installed through the movable pressure plate, and magnetic stripe 2 is fixedly installed on both the left and right ends of the inner wall of the fermentation box corresponding to the magnetic stripe 1.

[0014] Preferably, a vibrating block is abutting against the middle of the upper end of the baffle, a magnetic strip rod is fixedly installed on the upper end of the vibrating block, and magnetic strips are fixedly installed on the left and right sides of the upper end of the sleeve corresponding to the magnetic strip rod.

[0015] Preferably, an L-shaped plate is slidably mounted through the upper end of the magnetic strip, the lower end of the L-shaped plate is fixedly mounted on the baffle, and springs are sleeved on the outer side of the magnetic strip.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the heating and humidifying device inside the fermentation chamber is activated to ferment the tea leaves inside the storage container. Then, the motor is started to drive the square telescopic rod, the reciprocating screw, and the storage container to rotate. The reciprocating screw moves up and down on the support plate, simultaneously driving the storage container to move up and down synchronously. At this time, the square telescopic rod will extend and retract adaptively. When the storage container rotates and moves up and down, it will also drive the sleeve plate to slide up and down synchronously on the inner wall of the fermentation chamber. The sleeve plate will drive the movable pressure plate, the lifting nozzle pipe, and the anti-stacking nozzle pipe to move up and down synchronously. When the movable pressure plate moves downward, it will compress the air bag, causing the gas inside the air bag to be ejected from the lifting nozzle pipe and the anti-stacking nozzle pipe through the channels inside the movable pressure plate. The gas ejected from the lifting nozzle pipe will blow the tea leaves at the bottom of the storage container upward, allowing the tea leaves at the bottom of the storage container to turn over, thereby ensuring that the tea leaves inside the storage container are evenly heated and moisturized, thus improving the fermentation quality of the tea leaves.

[0017] 2. In this invention, the anti-piling nozzle pipe facilitates the blowing of tea leaves that have gathered at the inner edge of the storage bucket towards the center of the bucket under centrifugal force during the bucket's rotation. The centrifugal force generated by the bucket's rotation then disperses the tea leaves towards the inner edge, improving the quality of tea leaf agitation and preventing the tea leaves from piling up at the edge of the bucket, thus ensuring even heating and moisture absorption for fermentation. Furthermore, the pneumatic turning method avoids the damage and breakage that can occur with traditional stirring leaves, thus guaranteeing the integrity of the tea leaves and improving the processing quality.

[0018] 3. In this invention, when the storage bin rotates, it also drives the push block and the inclined block to rotate synchronously. When the inclined block is squeezed by the top block, it will drive the push block to slide upward inside the storage bin. Combined with the inclined surface at the upper end of the push block, it is beneficial to push the tea leaves located at the inner edge of the storage bin to the inner center of the storage bin. This facilitates the turning of the tea leaves and also avoids excessive accumulation of tea leaves at the inner edge of the storage bin, which would prevent the anti-piling nozzle from turning the tea leaves. This improves the quality and efficiency of the anti-piling nozzle in turning the tea leaves, and indirectly improves the fermentation quality of the tea leaves.

[0019] 4. In this invention, when the motor output shaft rotates, it also drives the eccentric wheel to rotate synchronously. When the eccentric wheel rotates away from the guide rod, the sealing plate and the guide rod will slide backward adaptively under the action of the spring. Similarly, when the eccentric wheel rotates one revolution, it will continue to squeeze the guide rod, pushing the guide rod and the sealing plate to reset. At this time, the spring will be stretched, realizing the intermittent opening and closing of the feeding port, thus realizing the intermittent feeding of tea leaves. This avoids feeding too much tea leaves at once, causing the tea leaves to accumulate too much on one side of the storage bucket (the storage bucket moves up and down, and when the storage bucket moves up and down, there is a drop between the storage bucket and the feeding port, so that the tea leaves can be evenly fed to different positions inside the storage bucket). This prevents the lifting nozzle pipe and the anti-stacking nozzle pipe from blowing and turning the tea leaves normally.

[0020] 5. In this invention, when the sleeve plate descends, it also drives the baffle and magnetic strip one to descend synchronously. When magnetic strip one descends to the side close to magnetic strip two, it will be subjected to magnetic repulsion, pushing magnetic strip one and the baffle on the sleeve plate toward the upper end of the storage bucket, stretching spring one. The baffle is designed to block the left and right sides of the upper end of the storage bucket, preventing the tea leaves from being sprayed off the upper end of the storage bucket to the outside of the storage bucket when the nozzle pipe is raised to spray air onto the tea leaves inside the storage bucket. This ensures the integrity of the tea leaves inside the storage bucket and avoids waste of tea leaves.

[0021] 6. In this invention, the blocking strip is designed to prevent tea leaves from splashing out from the bottom of the baffle, thereby further improving the blocking efficiency of the baffle.

[0022] 7. In this invention, when the baffle moves closer to the upper end of the storage bin, it also drives the L-shaped plate, magnetic strip rod, and vibrating block to move synchronously. When the magnetic strip rod moves to the lower side of the magnetic strip three, it will be attracted by magnetic force, which will drive the magnetic strip rod and the vibrating block to rise and compress the second spring. When the magnetic strip rod moves away from the lower side of the magnetic strip three, the second spring will drive the vibrating block and the magnetic strip rod to fall down and reset. The vibrating block is designed to vibrate the baffle, which helps to shake the tea leaves adhering to the lower end of the baffle back into the storage bin below. This prevents the tea leaves adhering to the lower end of the baffle from being carried to the outside of the storage bin when the baffle resets, thus ensuring the fermentation quality of the tea leaves and reducing waste.

[0026] Reference Figures 1-12 A tea fermentation device for processing tea leaves includes a fermentation box 1, a storage bucket 2 inside the fermentation box 1, a sealed door at the front end of the fermentation box 1, and a heating and humidifying device for fermenting tea leaves inside the fermentation box 1. A turning mechanism is also provided for turning the tea leaves inside the storage bucket 2. The turning mechanism includes a reciprocating screw 3 fixedly installed at the center of the bottom end inside the storage bucket 2. A support plate 4 is threaded onto the outer side of the reciprocating screw 3. The rear end of the support plate 4 is fixedly connected to the inner wall of the fermentation box 1. A square telescopic rod 5 is fixedly installed at the upper end of the reciprocating screw 3. A motor 6 is fixedly installed at the upper end of the fermentation box 1. The output shaft of the motor 6 is rotatably mounted through the upper end of the fermentation box 1, and the upper end of the square telescopic rod 5 is fixedly connected to the output shaft of the motor 6. A sleeve plate 7 is rotatably installed on the outer side, and both ends of the sleeve plate 7 are slidably connected to the inner wall of the fermentation box 1. A lifting nozzle pipe 8 is provided on the lower side of the storage bucket 2, and anti-piling nozzle pipes 9 are provided on the lower front and rear sides of the storage bucket 2. The anti-piling nozzle pipes 9 are interconnected with the lifting nozzle pipe 8. A movable pressure plate 10 is fixedly installed on the left end of the lifting nozzle pipe 8. The movable pressure plate 10 is fixedly installed on the sleeve plate 7 from bottom to top and slidably installed on the upper end of the fermentation box 1. An air bag 11 is fixedly installed on the upper end of the fermentation box 1. On the movable pressure plate 10, a channel is provided inside for communication between the airbag 11 and the lifting nozzle pipe 8 and the anti-stacking nozzle pipe 9. At least ten push blocks 21 are slidably installed at equal intervals along the lower edge of the storage tank 2. The upper ends of the push blocks 21 are inclined towards the center of the storage tank 2. Each push block 21 has a fixed inclined block 22 at its lower end, and a top block 23 is fixedly installed on the upper end of the anti-stacking nozzle pipe 9 corresponding to the inclined block 22. A material box 24 is fixedly installed on the upper end of the fermentation box 1. A discharge port 25 is provided at the upper end of the box 1 corresponding to the outlet of the material box 24. A sealing plate 26 is slidably installed at the lower end of the discharge port 25. A guide rod 27 is fixedly installed at the rear end of the sealing plate 26. An eccentric wheel 28 is abutted and fitted at the rear end of the guide rod 27. The eccentric wheel 28 is fixedly connected to the output shaft of the motor 6. A vertical plate 29 is slidably installed through the rear end of the guide rod 27. The upper end of the vertical plate 29 is fixedly installed at the top of the fermentation box 1. A spring 30 is sleeved on the outer side of the guide rod 27. The two ends of the spring 30 are fixedly connected to the sealing plate 26 and the vertical plate 29 respectively. During operation, the heating and humidifying device inside the fermentation chamber 1 is activated to ferment the tea leaves inside the storage tank 2. Then, the motor 6 is started, driving the square telescopic rod 5, the reciprocating screw 3, and the storage tank 2 to rotate. The reciprocating screw 3 moves up and down on the support plate 4, simultaneously causing the storage tank 2 to move up and down synchronously. At this time, the square telescopic rod 5 will extend and retract adaptively. When the storage tank 2 rotates and moves up and down, it also causes the sleeve plate 7 to slide up and down synchronously on the inner wall of the fermentation chamber 1. The sleeve plate 7 causes the movable pressure plate 10, the lifting nozzle pipe 8, and the anti-stacking nozzle pipe 9 to move up and down synchronously. When the movable pressure plate 10 moves downward, it compresses the air bag 11, causing the gas inside the air bag 11 to pass through the channels inside the movable pressure plate 10 and exit through the lifting nozzle pipe 8. The gas ejected from the anti-piling nozzle pipe 9 and the lifting nozzle pipe 8 facilitates the upward blowing of tea leaves located at the bottom of the storage container 2, allowing the tea leaves at the bottom of the storage container 2 to turn over. This ensures that the tea leaves inside the storage container 2 are evenly heated and moistened, thereby improving the fermentation quality of the tea. The anti-piling nozzle pipe 9 also facilitates the blowing of tea leaves that have gathered at the inner edge of the storage container 2 under the action of centrifugal force when the storage container 2 rotates towards the center of the storage container 2. The centrifugal force generated by the rotation of the storage container 2 then disperses the tea leaves towards the inner edge of the storage container 2, which also helps to improve the quality of tea leaf turning and avoids the situation where tea leaves accumulate at the edge of the storage container 2 and cannot be evenly heated and moistened for fermentation. This improves the fermentation quality of the tea. Furthermore, the pneumatic turning method is employed. This design avoids the damage and breakage that can easily occur when traditional stirring leaves turn the tea leaves over, thus ensuring the integrity of the tea leaves and improving the processing quality. When the storage bin 2 rotates, it also drives the push block 21 and the inclined block 22 to rotate synchronously. When the inclined block 22 is squeezed by the top block 23, it causes the push block 21 to slide upward inside the storage bin 2. Combined with the inclined surface at the upper end of the push block 21, this helps to push the tea leaves located at the inner edge of the storage bin 2 towards the inner center, facilitating the turning of the tea leaves. It also prevents excessive accumulation of tea leaves at the inner edge of the storage bin 2, which could prevent the anti-piling nozzle pipe 9 from turning the tea leaves. This improves the quality and efficiency of the anti-piling nozzle pipe 9 in turning the tea leaves, indirectly improving the fermentation quality of the tea leaves. 2. An internal locking block is provided for the push block 21. When the inclined block 22 separates from the top block 23, the inclined block 22 and the push block 21 will slide downwards and reset under the action of gravity. The locking block restricts the push block 21 from sliding further downwards, keeping the upper end of the push block 21 relatively horizontal with the bottom of the storage bin 2. When the output shaft of the motor 6 rotates, it will also drive the eccentric wheel 28 to rotate synchronously. When the eccentric wheel 28 rotates away from the guide rod 27, the sealing plate 26 and the guide rod 27 will slide backwards adaptively under the action of the spring 30. Similarly, when the eccentric wheel 28 rotates one revolution, it will continue to squeeze the guide rod 27, pushing the guide rod 27 and the sealing plate 26 to reset. At this time, the spring 30 will be stretched, realizing the intermittent opening and closing of the discharge port 25, thus realizing the intermittent feeding of tea leaves.This avoids the situation where too much tea is fed at once, causing excessive accumulation of tea leaves on one side of the storage bin 2 (the storage bin 2 moves up and down, creating a height difference between the storage bin 2 and the feeding port 25, thus ensuring even distribution of tea leaves to different positions inside the storage bin 2), preventing the lifting nozzle pipe 8 and the anti-stallization nozzle pipe 9 from properly blowing and turning the tea leaves.

[0027] As an embodiment of the present invention, a leak-proof mechanism is also provided to prevent tea leaves from leaking out from the top of the storage container 2 when the tea leaves inside the storage container 2 are stirred. The leak-proof mechanism includes baffles 12 symmetrically arranged on the left and right sides of the top of the storage container 2. At least three blocking strips 1201 are fixedly installed on the lower end of each baffle 12. The lower end of the baffle 12 is slidably installed on the sleeve plate 7. A spring 13 is fixedly installed on the opposite ends of each baffle 12. The opposite ends of each spring 13 are fixedly connected to the sleeve plate 7. A magnetic strip is fixedly installed on the upper end of each baffle 12. Magnetic strip 14 on the left side is movably installed on the movable pressure plate 10, and magnetic strip 2 15 is fixedly installed on both the left and right ends of the inner wall of fermentation box 1, corresponding to magnetic strip 14. Vibration block 16 is abutted and attached to the middle of the upper end of the baffle 12. Magnetic strip rod 17 is fixedly installed on the upper end of vibration block 16, and magnetic strip 3 20 is fixedly installed on the left and right sides of the upper end of sleeve plate 7, corresponding to magnetic strip rod 17. L-shaped plate 18 is slidably installed through the upper end of magnetic strip rod 17, and the lower end of L-shaped plate 18 is fixedly installed on baffle 12. Spring 2 19 is sleeved on the outer side of magnetic strip rod 17. During operation, when the sleeve 7 descends, it also causes the baffle 12 and magnetic strip 14 to descend synchronously. When magnetic strip 14 descends to the side close to magnetic strip 15, it will be subjected to magnetic repulsion, pushing magnetic strip 14 and baffle 12 on the sleeve 7 towards the upper end of the storage bin 2, stretching spring 13. The baffle 12 is designed to shield the left and right sides of the upper end of the storage bin 2, preventing tea leaves from being sprayed off the upper end of the storage bin 2 and falling to the outside of the storage bin 2 when the nozzle pipe 8 sprays air onto the tea leaves inside the storage bin 2. This ensures the integrity of the tea leaves inside the storage bin 2 and avoids waste. The blocking strip 1201 is designed to prevent tea leaves below the baffle 12 from splashing out, further improving the performance of the baffle 12. The blocking efficiency is such that when the baffle 12 moves closer to the upper end of the storage bin 2, it also drives the L-shaped plate 18, magnetic strip 17, and vibrating block 16 to move synchronously. When the magnetic strip 17 moves to the lower side of the magnetic strip 20, it will be attracted by the magnetic force, which will drive the magnetic strip 17 and the vibrating block 16 to rise and compress the spring 19. When the magnetic strip 17 moves away from the lower side of the magnetic strip 20, the spring 19 will drive the vibrating block 16 and the magnetic strip 17 to fall and reset. The vibrating block 16 is designed to vibrate the baffle 12, which helps to shake the tea leaves adhering to the lower end of the baffle 12 back into the storage bin 2. This prevents the tea leaves adhering to the lower end of the baffle 12 from being carried to the outside of the storage bin 2 when the baffle 12 resets, thus ensuring the fermentation quality of the tea leaves and reducing waste.

[0028] Working principle: When using this invention, the heating and humidifying device inside the fermentation chamber 1 is activated to ferment the tea leaves inside the storage container 2. Then, the motor 6 is started to drive the square telescopic rod 5, the reciprocating screw 3, and the storage container 2 to rotate. The reciprocating screw 3 will move up and down on the support plate 4, and at the same time, it will drive the storage container 2 to move up and down synchronously. At this time, the square telescopic rod 5 will extend and retract adaptively. When the storage container 2 rotates and moves up and down, it will also drive the sleeve plate 7 to slide up and down synchronously on the inner wall of the fermentation chamber 1. The sleeve plate 7 will drive the movable pressure plate 10, the lifting nozzle pipe 8, and the anti-stacking nozzle pipe 9 to move up and down synchronously. When the movable pressure plate 10 moves downward, it will compress the air bag 11, causing the gas in the air bag 11 to pass through the channels inside the movable pressure plate 10 and exit through the lifting nozzle. The gas ejected from pipe 8 and anti-piling nozzle pipe 9 blows upwards from the nozzle pipe 8, allowing the tea leaves at the bottom of the storage container 2 to turn over. This ensures that the tea leaves inside the storage container 2 are heated and moistened evenly, thus improving the fermentation quality. The anti-piling nozzle pipe 9 blows the tea leaves that have gathered at the inner edge of the storage container 2 under centrifugal force during rotation towards the center of the storage container 2. The centrifugal force generated by the rotation of the storage container 2 then disperses the tea leaves towards the inner edge, further improving the turning quality and preventing the tea leaves from piling up at the edge of the storage container 2, which would hinder even heating and moistening during fermentation. This improves the fermentation quality of the tea leaves. Furthermore, the pneumatic turning mechanism... This method avoids the damage and breakage that can easily occur when traditional stirring and turning of tea leaves, thus ensuring the integrity of the tea and improving the processing quality. When the storage bin 2 rotates, it also drives the push block 21 and the inclined block 22 to rotate synchronously. When the inclined block 22 is squeezed by the top block 23, it causes the push block 21 to slide upward inside the storage bin 2. Combined with the inclined surface at the upper end of the push block 21, this helps to push the tea leaves located at the inner edge of the storage bin 2 towards the inner center, facilitating the turning of the tea leaves. It also prevents excessive accumulation of tea leaves at the inner edge of the storage bin 2, which could prevent the anti-piling nozzle pipe 9 from turning the tea leaves. This improves the quality and efficiency of the anti-piling nozzle pipe 9 in turning the tea leaves, indirectly improving the fermentation quality of the tea. Inside the bucket 2, a locking block is provided corresponding to the push block 21. When the inclined block 22 separates from the top block 23, the inclined block 22 and the push block 21 will slide downwards and reset under the action of gravity. The locking block restricts the push block 21 from sliding further downwards, keeping the upper end of the push block 21 in a relatively horizontal position with the bottom of the storage bucket 2. When the output shaft of the motor 6 rotates, it will also drive the eccentric wheel 28 to rotate synchronously. When the eccentric wheel 28 rotates away from the guide rod 27, the sealing plate 26 and the guide rod 27 will slide backward adaptively under the action of the spring 30. Similarly, when the eccentric wheel 28 rotates one revolution, the eccentric wheel 28 will continue to squeeze the guide rod 27, pushing the guide rod 27 and the sealing plate 26 to reset. At this time, the spring 30 will be stretched, realizing the intermittent opening and closing of the discharge port 25, thus realizing the intermittent feeding of tea leaves.This design avoids excessive tea leaves being fed at once, which could cause excessive tea leaf accumulation on one side of the storage bin 2 (the storage bin 2 moves up and down, creating a height difference between the storage bin 2 and the feeding port 25, allowing for even distribution of tea leaves to different positions inside the storage bin 2). This prevents the lifting nozzle pipe 8 and the anti-stallization nozzle pipe 9 from properly blowing and turning the tea leaves. When the sleeve plate 7 descends, it also drives the baffle plate 12 and magnetic strip 14 to descend simultaneously. When magnetic strip 14 descends to the side near magnetic strip 15, it experiences magnetic repulsion, pushing magnetic strip 14 and baffle plate 12 towards the upper end of the storage bin 2 on the sleeve plate 7, stretching spring 13. The baffle plate 12 effectively blocks the upper left and right sides of the storage bin 2, preventing tea leaves from being sprayed from the upper end of the storage bin 2 onto the outside when the lifting nozzle pipe 8 blows air into the tea leaves inside the storage bin 2, thus ensuring the storage bin... The integrity of the tea leaves inside the baffle 12 is maintained, avoiding waste. The baffle strip 1201 prevents tea leaves from splashing out from the lower end of the baffle 12, further improving the baffle 12's blocking efficiency. When the baffle 12 moves closer to the upper end of the storage bin 2, it also drives the L-shaped plate 18, magnetic strip 17, and vibrating block 16 to move synchronously. When the magnetic strip 17 moves to the lower side of the magnetic strip 20, it will be attracted by the magnetic force, causing the magnetic strip 17 and vibrating block 16 to rise and compress spring 19. When the magnetic strip 17 moves away from the lower side of the magnetic strip 20, spring 19 causes the vibrating block 16 and magnetic strip 17 to descend and reset. The vibrating block 16 facilitates the vibration of the baffle 12, which helps to shake the tea leaves adhering to the lower end of the baffle 12 back into the storage bin 2, preventing the tea leaves adhering to the lower end of the baffle 12 from being carried to the outside of the storage bin 2 when the baffle 12 resets, ensuring the fermentation quality of the tea leaves and reducing waste.
