[0020] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] like Figure 1-Figure 5 As shown, a Liubao raw tea preparation process based on automatic quality detection includes the following steps: Step 1: Initially knead the tea leaves after storage. The initial kneading is the first twisting. The first twisting destroys the tea cell tissue, promotes the exudation of tea juice, is beneficial to the enzymatic reaction in the subsequent fermentation process, and enhances the foundation for the formation of tea aroma and taste.

[0022] Step 2: The tea leaves are first fermented in a pile, and the tea leaves in the pile are sprayed with water and a temperature detector is inserted into the tea pile; Through the initial pile fermentation, suitable temperature and humidity are used to promote microbial metabolism and start the fermentation and conversion process of tea. Water spraying is used to adjust the moisture content of the piled tea, maintain a suitable fermentation environment, and prevent the tea from drying out. The temperature detector monitors the pile temperature changes in real time to ensure the controllability and uniformity of the fermentation process.

[0023] Step 3: At regular intervals, retrieve the temperature detector, use the automatic turning mechanism to turn the tea leaves over, and then reinsert the temperature detector into the tea pile; By turning the tea pile regularly, the temperature and humidity in the tea pile are evenly distributed, avoiding local overheating or insufficient fermentation. The automated turning mechanism improves operating efficiency and the stability of fermentation quality. The recovery and reinsertion of the temperature detector can prevent damage to the temperature detector during turning.

[0024] Step 4: Roll the tea leaves twice, which is the second rolling. Step 5: The tea leaves are fermented for the second time, and the tea leaves in the fermentation pile are sprayed with water, and a temperature detector is inserted into the tea pile; Through the second pile fermentation, the fermentation transformation of the tea is deepened and the quality characteristics of the tea are enriched. Water is sprayed again to adjust the moisture and maintain good fermentation conditions. The temperature detector continues to monitor the temperature changes to ensure accurate management of the fermentation process.

[0025] The second rolling further destroys the structure of the tea leaves, promotes the release of internal substances, enhances the aroma and flavor of the tea leaves after fermentation, and prepares them for subsequent secondary fermentation.

[0026] Step 6. Repeat step 3.

[0027] The innovative technology of one storage, double fermentation and double kneading is used to produce Liubao raw tea, which achieves the high-quality characteristics of Liubao raw tea with tight and oily brown tea leaves, yellow-red soup color, bright yellow leaf bottom and mellow taste, avoiding the bitterness and dark green color of green tea. The loss rate of Liubao tea in deep processing is reduced by 10%-15%, and the fermentation time is reduced by about 50%, thereby reducing the production time of Liubao tea, accelerating the capital flow of the enterprise, and promoting the improvement of the enterprise's efficiency.

[0033] According to an optional embodiment of the present invention, two sliding parts 24 are fixed to the bottom wall of the displacement seat 1 , and the two sliding parts 24 are both slidably connected to the guide rail 3 , and the guide rail 3 is located between the two sliding parts 24 .

[0034] According to an optional embodiment of the present invention, the limiting block 16 is located on the right side of the limiting shaft 14 so that the bottom wall of the limiting block 16 can abut against the top wall of the right end of the supporting plate 13 .

[0035] According to an optional embodiment of the present invention, in step 2 and step 5, the temperature detectors are inserted into the upper layer, middle layer and lower layer of the tea pile, so as to monitor the fermentation temperature of the tea pile in all directions.

[0036] According to an optional embodiment of the present invention, a wireless module is provided in the temperature detector, which can automatically transmit temperature data to an external terminal device in real time, so as to facilitate staff and external monitoring systems to monitor the temperature of different positions of the tea pile in real time, thereby automatically detecting the fermentation quality of the tea pile.

[0037] Implementation process: First, install the guide rail 3 on the ground. The specific installation method is not limited and can be connected by screws or casting.

[0038] Working principle of turning pile: In the initial state, Figure 1-Figure 2As shown, the supporting plate 13 is in a horizontal state, the supporting plate 13 and the bottom wall of the loading chamber 21 are in abutment against each other, the bottom wall of the limit block 16 and the top wall of the supporting plate 13 are in abutment against each other, the locking piece 17 is inserted into the groove 201 and locked with the press-type elastic self-locking mechanism, the second permanent magnet 22 magnetically attracts the first permanent magnet 19, the locking piece 17 is inserted to the lower limit position in the groove 201, the elastic member 18 is in a stretched state, and the third gear 31 and the fourth gear 33 and the fifth gear 39 are not engaged.

[0039] The second motor 25 is turned on, and the output shaft of the second motor 25 rotates at a high speed. After being decelerated by the reducer 26, it drives the second gear 27 to rotate slowly. Since the second gear 27 is engaged with the transmission tooth 28, the second gear 27 will drive the displacement seat 1, the guide seat 4, and the turning box 5 to move along the extension direction of the guide rail 3 when it rotates on the transmission tooth 28. When the turning box 5 moves to the right of the tea leaves that need to be turned, the second motor 25 stops running, and the piston rod on the hydraulic cylinder 2 extends to cause the turning box 5 to move to the left, and the shovel head 38 scoops up the tea leaves, and the tea leaves enter the loading chamber 21. The piston rod of the hydraulic cylinder 2 is shortened, and the turning box 5 moves to the right. The first motor 10 is turned on to drive the first gear 11 to rotate counterclockwise, and the turning box 5 will move up along the guide seat 4, and the tooth plate 12 will move up along the inner wall of the plate channel 8. The second permanent magnet 22 releases the first permanent magnet The top wall of the material support plate 13 is inclined and the inclination angle of the inclined surface is very small, so the material support plate 13 moves upward with the tea leaves, and the upper layer of tea leaves in the loading chamber 21 first resists against the top wall of the loading chamber 21. Since the top wall of the loading chamber 21 is an inclined surface with a higher left and a lower right side, the top wall of the loading chamber 21 will generate a left component force on the tea leaves, thereby causing the tea leaves to gradually leave the loading chamber 21 to the left, first the upper layer of tea leaves leave the loading chamber 21, then the middle layer of tea leaves leave the loading chamber 21, and finally the lower layer of tea leaves leave the loading chamber 21.

[0040] When the supporting plate 13 and the lowest point of the top wall of the loading chamber 21 are against each other, there is still a small amount of tea on the top wall of the supporting plate 13. The pressing block 23 presses the lifting plate 15 downwards a short distance, so that the locking plate 17 moves down a short distance, thereby releasing the lock of the locking plate 17 and the press-type elastic self-locking mechanism, reversing the first motor 10, the tooth plate 12 moves downwards, and the lifting plate 15, the limit block 16, and the locking plate 17 move upwards relative to the tooth plate 12 under the elastic force of the elastic member 18, the limit block 16 is released from the resistance against the supporting plate 13, and the supporting plate 13 rotates counterclockwise around the limit shaft 14. After the supporting plate 13 tilts to the left at a certain angle, the limit shaft The limiting function of 14 can keep the supporting plate 13 in its current tilted state, the tea leaves on the supporting plate 13 will slide out of the loading chamber 21, the tooth plate 12 continues to move downward, the second permanent magnet 22 magnetically attracts the first permanent magnet 19, the first permanent magnet 19 overcomes the elastic force of the elastic member 18 and moves downward, the locking piece 17 is inserted into the groove 201 and locked with the press-type elastic self-locking mechanism, the supporting plate 13 and the bottom wall of the loading chamber 21 are against each other, the bottom wall of the limiting block 16 and the top wall of the right end of the supporting plate 13 are against each other, the reset is completed, and then the turning box 5 is continued to be driven by the second motor 25 to move to the right of the next pile of tea, and the above method is used to turn the next pile of tea.

[0041] Water spray working principle: The third gear 31 is moved to engage the switching seat 30 with the fifth gear 39 and the fourth gear 33. The first motor 10 is used to move the turning box 5 up to the bottom wall above the tea pile. The piston rod on the hydraulic cylinder 2 is used to control the turning box 5 to move above the tea pile. The second motor 25 is turned on. The second motor 25 moves the turning box 5 along the guide rail 3. At the same time, the fifth gear 39 on the output shaft of the second motor 25 rotates, thereby rotating the third gear 31, the fourth gear 33, the linkage rod 34 and the impeller in the pump body 32. The high-speed rotation of the impeller generates centrifugal force, thereby drawing clean water from the water tank 29 into the second liquid guide pipe 36, and then the clean water is sprayed from each nozzle 37 into the tea pile to promote fermentation and control humidity.

[0042] The present invention drives the hydraulic cylinder 2 to allow the tea pile to enter the supporting plate 13 in the loading chamber 21. The first motor 10 drives the supporting plate 13 to move upward. The supporting plate 13 utilizes the inclined top wall of the loading chamber 21 and cooperates with the automatically tilted supporting plate 13 to cause the upper layer, middle layer and lower layer of tea leaves in the loading chamber 21 to fall out of the loading chamber 21 in sequence, thereby automatically turning the tea leaves. The tea leaves are dispersed in the air to prevent them from clumping. The second motor 25 drives multiple tea piles to be automatically turned without manual turning, thereby greatly reducing labor costs and improving production efficiency. The automatic compost turning mechanism can not only realize automatic compost turning, but also realize automatic water spraying. Appropriate water spraying can increase the water content of tea, provide a good living environment for fermentation microorganisms, promote microbial metabolism, thereby accelerating the fermentation process, and enhancing the aroma and taste of tea. At the same time, maintaining appropriate humidity is conducive to uniform fermentation.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
