Description

Technical Field

[0001] The present invention relates to the technical field of withering machines, and particularly to a withering machine for tea processing. Background Art

[0002] Withering is a process in tea production, aiming to damage the leaf margin cells, promote the enzymatic oxidation process, make the leaves change from hard to soft, and induce the escape of tea aroma. In the existing process, the tea leaves are directly loaded into the withering machine for withering after being spread out. The tea leaves may carry some impurities during picking and spreading. If not processed and rotated together in the withering machine for withering, it may affect the fragrance type and quality of the tea leaves.

[0003] The existing withering machine clamps the sieve with tea leaves on the withering machine, and drives the sieve to rotate through the withering machine to complete the withering work by simulating manual operation. However, the withering machine has a single mechanical movement, resulting in uneven withering of the tea leaves, affecting the fermentation of the tea leaves. It is necessary to manually fix the sieve on the withering machine and manually disassemble it after the withering work is completed. Moreover, the tea leaves are exposed to the air, and the tea leaves are sieved out of the sieve during the shaking process, resulting in waste of the tea leaves. The degree of withering required needs to be judged manually and cannot be adjusted according to the quality of the tea leaves, thus affecting the quality of the tea leaves. Summary of the Invention

[0004] Based on the technical problems that the existing withering machine has a single mechanical movement, the tea leaves are sieved out of the sieve during the shaking process, resulting in waste of the tea leaves, and the withering degree cannot be adjusted according to the quality of the tea leaves, thus affecting the quality of the tea leaves, the present invention proposes a withering machine for tea processing.

[0005] A withering machine for tea processing proposed by the present invention includes a bracket, and further includes a swinging device and a withering device installed on the bracket.

[0006] The swinging device is located on the outer surface of the bracket and drives the withering device to rotate. The swinging device includes a swinging mechanism and a sieving mechanism. The swinging mechanism drives the sieving mechanism to rotate, and the sieving mechanism sieves the tea leaves.

[0007] The withering device is located inside the swinging device and withers the tea leaves in the sieving mechanism. The withering device includes a driving mechanism and a withering mechanism. The driving mechanism drives the withering mechanism to shake, and the withering mechanism withers the tea leaves.

[0008] Preferably, the swinging mechanism includes a swinging motor fixedly installed on the outer surface of the bracket. The outer surface of the bracket is rotatably connected with a swinging frame through a bearing, and one end of the output shaft of the swinging motor is fixedly installed on the outer surface of the swinging frame.

[0009] Through the above technical solution, the start of the swing motor drives the swing frame to rotate, and the swing frame can drive the sieving mechanism to turn over, so that the tea leaves can be turned over and mixed, making the withering more uniform.

[0010] Preferably, the sieving mechanism includes a rotating cylinder with a discharge port. The rotating cylinder is rotatably connected to the inner surface of the swing frame through a bearing. One end of the swing frame is rotatably connected to a rotating sleeve through a bearing. One end of the swing frame is rotatably connected to a telescopic rod through a bearing. One end of the telescopic rod is fixedly installed with a screen assembly with a discharge port and a roller. The roller is rotatably connected to the outer surface of the discharge port of the screen assembly. The outer surface of the roller contacts the inner wall of the rotating cylinder. The screen assembly is composed of a frame and a screen fixed on the frame. One end of the screen assembly of the screen assembly is slidably inserted into the inner wall of the rotating sleeve. The outer surface of the swing frame is fixedly installed with an electric push rod. One end of the push rod of the electric push rod is fixedly installed with one end of the screen assembly.

[0011] Through the above technical solution, the rotation of the rotating cylinder can drive the screen assembly to rotate. The screen on the screen assembly can screen impurities or tea stalks in the tea leaves, so that the impurities and tea stalks can enter the rotating cylinder through the screen and be collected through the discharge port in the rotating cylinder. The electric push rod can push the screen assembly to move in the rotating cylinder, thereby adjusting the position of the screen assembly. The roller can make the discharge port of the screen assembly contact the inner wall of the rotating cylinder to seal the discharge port, so that when the screen assembly rotates in the rotating cylinder, it can prevent the tea leaves from leaking through the discharge port.

[0012] Preferably, a rotating motor is fixedly installed on the outer surface of the swing frame. One end of the output shaft of the rotating motor drives the rotating sleeve to rotate through the cooperation of a synchronous belt and a synchronous pulley. A limiting ring is fixedly installed on the inner wall of the rotating cylinder. A driving block is fixedly installed on the outer surface of the screen assembly. After the screen assembly is pushed by the electric push rod, the outer surface of the limiting ring is slidably inserted into the outer surface of the driving block.

[0013] Through the above technical solution, the rotating motor drives the rotating sleeve to rotate, and the rotating sleeve can drive the screen assembly to rotate, so that the screen assembly can drive the tea leaves inside to flip, completing the stirring work of the tea leaves. The tea leaves collide with each other to complete the withering work. By moving the screen assembly, the driving block is inserted into the limiting ring of the inner rotating cylinder of the machine, so that the rotation of the screen assembly can drive the rotating cylinder to rotate synchronously, so as to adjust the position of the discharge port of the rotating cylinder. When the discharge ports of the rotating cylinder and the screen assembly face downward, the withered tea leaves can be poured out. When the discharge port of the rotating cylinder and the screen assembly both face upward, it is convenient to pour tea leaves into the screen assembly. At the same time, when the discharge port of the rotating cylinder faces upward and the limiting ring is separated from the driving block, the rotation of the screen assembly will not cause the tea leaves to spill out.

[0014] Preferably, the driving mechanism includes a driving motor, the driving motor is fixedly installed on the outer surface of the swing frame, a driving magnetic ring is fixedly installed at one end of the output shaft of the driving motor, a connecting frame is fixedly installed on the inner wall of the screen assembly, a transmission rod with a gear is rotatably connected to the outer surface of the connecting frame through a bearing, a driven magnetic ring is fixedly installed at one end of the transmission rod, the outer surface of the driving magnetic ring is magnetically connected to the outer surface of the driven magnetic ring, a driving rod with a gear is rotatably connected to the outer surface of the bracket through a bearing, one end of the driving rod is rotatably connected to a connecting seat through a bearing, a deflection motor is fixedly installed on the outer surface of the connecting frame, one end of the output shaft of the deflection motor is fixedly installed on the outer surface of the connecting seat, a swing rod is fixedly installed on the outer surface of the connecting seat, a universal coupling is rotatably connected to the outer surface of the connecting frame, and the outer surface of the swing rod is hinged to the outer surface of the universal coupling through a pin shaft.

[0015] Through the above technical solution, the driving motor can drive the driving magnetic ring to rotate. Through the transmission of the driving magnetic ring, the non-contact driven magnetic ring can be driven to rotate. After the deflection motor is started, it drives the swing rod to pull. Through the universal coupling, the withering mechanism can be driven to deflect, so that the rotation of the swing rod drives the withering mechanism to deflect and vibrate.

[0016] Preferably, the withering mechanism includes a fixed ring, a spherical connecting rod is hinged to the outer surface of the fixed ring, one end of the spherical connecting rod is hinged to the outer surface of another fixed ring, an annular support frame is fixedly installed on the inner wall of the screen assembly, the inner wall of the annular support frame is slidably inserted into the outer surface of the spherical connecting rod, and an inclined surface ring is fixedly installed on the inner wall of the screen assembly, and the outer surface of the inclined surface ring is in contact with the outer surface of the fixed ring.

[0017] Through the above technical solution, the fixed ring is hinged to other fixed rings through spherical connecting rods, and the spherical connecting rods are limited by annular brackets. The annular brackets can drive the leaf-shaking mechanism to rotate. At the same time, when the fixed ring deflects and vibrates, it can drive another fixed ring connected to it to deflect and vibrate synchronously, so as to batch-shake the tea leaves in the screen assembly, making the leaf shaking more uniform. The inclined plane ring seals the gap between the fixed ring and the inner wall of the screen assembly, facilitating the diversion of tea leaves, so that the tea leaves can be evenly distributed on the leaf-shaking mechanism and will not gather at the lower end of the screen assembly when the screen assembly is upright.

[0018] Preferably, a support frame is hinged to the inner wall of the fixed ring through a pin shaft. A bamboo woven screen plate is fixedly installed on the outer surface of the support frame. One end of the support frame is hinged to a fixed shaft through a pin shaft, and one end of a fixed shaft is fixedly installed with one end of the swing rod.

[0019] Through the above technical solution, the support frame can support the bamboo woven screen plate. The bamboo woven screen plates installed on both side surfaces of the support frame can shake the tea leaves on both sides of the fixed ring. The bamboo woven screen plate is convenient for leaf shaking. The bamboo woven screen plate is made of bamboo slices, thus reducing the damage of tea leaves during leaf shaking. The swing rod can drive the fixed ring to swing.

[0020] Preferably, a roller is rotatably connected to the outer surface of the fixed ring. A driving ring with a column is rotatably connected to the outer surface of the roller. One end of the support frame is fixedly installed with a deflecting plate with a chute, and one end of the column of the driving ring is slidably inserted into the inner wall of the deflecting plate.

[0021] Through the above technical solution, the roller can limit and support the driving ring. When the fixed ring rotates to drive the deflecting plate to deflect, the support frame can be driven to deflect, so that the support frame can become a stirring paddle to stir the tea leaves when the screen assembly rotates, facilitating the turning of the tea leaves.

[0022] Preferably, a driving arc groove is formed in the inner wall of the screen assembly, and one end of a column of the driving ring is slidably inserted into the inner wall of the driving arc groove.

[0023] Through the above technical solution, when the screen assembly moves, the driving arc groove can drive the driving ring to deflect. At the same time, when the screen assembly moves, the inclined plane ring and the fixed ring are separated, facilitating the unrestricted deflection and shaking of the fixed ring.

[0024] Preferably, a detection plate is fixedly mounted on the inner wall of the screen assembly, an industrial camera is fixedly mounted on the outer surface of the detection plate, a sensor assembly is fixedly mounted on the outer surface of the detection plate, and the sensor assembly includes a temperature sensor, a humidity sensor, a laser scattering sensor and a gas sensor.

[0025] Through the above technical scheme, multiple sensors in the sensor group are configured with a high-resolution industrial camera and an LED multi-band light source (405nm / 530nm / 660nm / 850nm), and the detection indicators are: chlorophyll content (660nm reflectivity) and polyphenol oxidase activity (405nm absorbance) and moisture content (850nm near-infrared absorbance). The laser scattering sensor uses a 650nm laser source and a photodiode array to measure the scattering pattern of light reflected from the surface of the tea leaves. Feature extraction: Hurst index analysis of surface texture complexity (H>0.7 for unshaken leaves, reduced to 0.5-0.6 after moderate shaking), gas sensor array (TGS2600 / TGS2620 / MP-9), detection of volatile organic compounds, linalool concentration (characteristic aroma of oolong tea) and linalool degradation rate (indicating fermentation progress).

[0026] The beneficial effects of the present invention are:

[0027] The tea leaves are then shaken by the sifting mechanism, and the tea leaves are then mixed and shaken more evenly. The screen assembly can be driven to rotate by the turning of the drum, and the screen on the screen assembly can screen out impurities or tea stems in the tea leaves, so that the impurities and tea stems can enter the drum through the screen and be collected through the discharge port in the drum. The rotating sleeve is driven to rotate by the rotating motor, and the rotating sleeve can drive the screen assembly to rotate, so that the screen assembly can turn the tea leaves inside, and complete the stirring of the tea leaves. The tea leaves collide with each other to complete the shaking of the tea leaves, and thus the tea leaves can have a variety of stirring methods, which solves the technical problems that the existing shaking machine has a single mechanical motion, causes the tea leaves to be screened out of the sieve during the shaking process, causes the tea leaves to be wasted, and cannot adjust the shaking degree according to the quality of the tea leaves, thereby affecting the quality of the tea leaves.

[0028] 2. By setting up a withering device, the tea leaves can be tilted and shaken to complete the withering work. After the deflection motor is started, it drives the swing rod to pull. Through the universal coupling, the withering mechanism can be driven to deflect. Thus, the rotation of the swing rod drives the withering mechanism to deflect and vibrate. Bamboo woven sieve plates are installed on both surfaces of the support frame, which can wither the tea leaves on both sides of the fixed ring. The bamboo woven sieve plates facilitate the withering of tea leaves. The bamboo woven sieve plates are made of bamboo slices, which reduces the damage of tea leaves during the withering process. Through the swing rod, the fixed ring can be driven to swing, so that the tea leaves can be shunted and withered, making the withering more uniform. Through the sensor component, the withering degree of the tea leaves can be detected, solving the technical problems of the existing withering machine with single mechanical movement, causing tea leaves to be screened out of the sieve during the shaking process, resulting in waste of tea leaves, and being unable to adjust the withering degree according to the quality of tea leaves, thus affecting the quality of tea leaves.

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0042] Refer to Figures 1-11 , a withering machine for tea processing, includes a support 1, and also includes a swing device and a withering device installed on the support 1.

[0043] As Figures 2-3 shown, in order to stir the tea, the swing device is located on the outer surface of the support 1 and drives the withering device to rotate. The swing device includes a swing mechanism and a sieving mechanism. The swing mechanism drives the sieving mechanism to rotate, and the sieving mechanism sieves the tea.

[0044] Specifically, in order to drive the sieving mechanism to rotate, the swing mechanism includes a swing motor 2. The swing motor 2 is fixedly installed on the outer surface of the support 1. The outer surface of the support 1 is rotatably connected to a swing frame 21 through a bearing. One end of the output shaft of the swing motor 2 is fixedly installed on the outer surface of the swing frame 21.

[0045] Specifically, in order to screen the tea leaves, the screening mechanism includes a rotating cylinder 3 with a discharge port. The rotating cylinder 3 is rotatably connected to the inner surface of the swing frame 21 through bearings. One end of the swing frame 21 is rotatably connected to a rotating sleeve 31 through a bearing, and one end of the swing frame 21 is rotatably connected to a telescopic rod 32 through a bearing. One end of the telescopic rod 32 is fixedly installed with a screen assembly 33 with a discharge port and a roller. When the discharge port of the screen assembly 33 is aligned with the discharge port of the rotating cylinder 3, feeding and discharging can be carried out. The roller is rotatably connected to the outer surface of the discharge port of the screen assembly 33, reducing the friction between the discharge port of the screen assembly 33 and the inner wall of the rotating cylinder 3. The outer surface of the roller contacts the inner wall of the rotating cylinder 3. In order to screen impurities in the tea leaves, the screen assembly 33 is composed of a frame and a screen fixed on the frame. One end of the screen of the screen assembly 33 is slidably inserted into the inner wall of the rotating sleeve 31. In order to push the screen assembly 33 to move, an electric push rod 34 is fixedly installed on the outer surface of the swing frame 21. One end of the push rod of the electric push rod 34 is fixedly installed with one end of the screen assembly 33.

[0046] Specifically, in order to drive the screen assembly 33 to rotate, a rotating motor 35 is fixedly installed on the outer surface of the swing frame 21. One end of the output shaft of the rotating motor 35 drives the rotating sleeve 31 to rotate through the cooperation of a synchronous belt and a synchronous pulley. In order to drive the rotating cylinder 3 to rotate, a limiting ring 36 is fixedly installed on the inner wall of the rotating cylinder 3. A driving block 37 is fixedly installed on the outer surface of the screen assembly 33. After the screen assembly 33 is pushed by the electric push rod 34, the outer surface of the limiting ring 36 slides and is inserted into the outer surface of the driving block 37.

[0047] Through the movement of the screen assembly 33, the driving block 37 is inserted into the limiting ring 36 of the inner rotating cylinder 3. Thus, the rotation of the screen assembly 33 can drive the rotating cylinder 3 to rotate synchronously, so as to adjust the position of the discharge port of the rotating cylinder 3. When the discharge ports of the rotating cylinder 3 and the screen assembly 33 are downward, the tea leaves after the withering can be poured out. When the discharge ports of both the rotating cylinder 3 and the screen assembly 33 are upward, it is convenient to pour the tea leaves into the screen assembly 33. At the same time, when the discharge port of the rotating cylinder 3 is upward and the limiting ring 36 is separated from the driving block 37, the rotation of the screen assembly 33 will not cause the tea leaves to spill.

[0048] As Figures 4-11 shown, in order to wither the tea leaves, the withering device is located inside the swinging device and withers the tea leaves in the screening mechanism. The withering device includes a driving mechanism and a withering mechanism. The driving mechanism drives the withering mechanism to shake, and the withering mechanism withers the tea leaves.

[0049] Specifically, in order to drive the withering mechanism to sway, the driving mechanism includes a driving motor 4, which is fixedly installed on the outer surface of the swing frame 21. One end of the output shaft of the driving motor 4 is fixedly installed with a driving magnetic ring 41. The inner wall of the screen assembly 33 is fixedly installed with a connecting frame 42. The outer surface of the connecting frame 42 is rotatably connected with a transmission rod 43 with a gear through a bearing. In order to drive the transmission rod 43 to rotate, one end of the transmission rod 43 is fixedly installed with a driven magnetic ring 44. The outer surface of the driving magnetic ring 41 is magnetically connected to the outer surface of the driven magnetic ring 44. The outer surface of the bracket 1 is rotatably connected with a driving rod 45 with a gear through a bearing. One end of the driving rod 45 is rotatably connected with a connecting seat 46 through a bearing. The outer surface of the connecting frame 42 is fixedly installed with a deflection motor 47. One end of the output shaft of the deflection motor 47 is fixedly installed with the outer surface of the connecting seat 46. The deflection motor 47 will rotate along with the screen assembly 33 and can be electrically conducted through a slip ring. The outer surface of the connecting seat 46 is fixedly installed with a swing rod 48. The outer surface of the connecting frame 42 is rotatably connected with a universal coupling 49. The universal coupling 49 can facilitate the deflection and swing of the swing rod 48 to complete the withering work. The outer surface of the swing rod 48 is hinged to the outer surface of the universal coupling 49 through a pin shaft.

[0050] Specifically, in order to shunt and wither the tea leaves to make the withering of the tea leaves more uniform, the withering mechanism includes a fixed ring 5. The outer surface of the fixed ring 5 is hinged with a spherical connecting rod 51. One end of the spherical connecting rod 51 is hinged with the outer surface of another fixed ring 5. In order to limit the spherical connecting rod 51, the inner wall of the screen assembly 33 is fixedly installed with an annular support 52. The inner wall of the annular support 52 is slidably inserted with the outer surface of the spherical connecting rod 51. The inner wall of the screen assembly 33 is fixedly installed with an inclined surface ring 53. The outer surface of the inclined surface ring 53 is in contact with the outer surface of the fixed ring 5.

[0051] Specifically, in order to complete the withering work and reduce the damage to the tea leaves, the inner wall of the fixed ring 5 is hinged with a support frame 54 through a pin shaft. The outer surface of the support frame 54 is fixedly installed with a bamboo woven screen plate 55. One end of the support frame 54 is hinged with a fixed shaft 56 through a pin shaft. One end of a fixed shaft 56 is fixedly installed with one end of the swing rod 48.

[0052] The support frame 54 can support the bamboo woven screen plate 55. The bamboo woven screen plates 55 installed on both side surfaces of the support frame 54 can wither the tea leaves on both sides of the fixed ring 5. The bamboo woven screen plate 55 can facilitate the withering of the tea leaves. The bamboo woven screen plate 55 is made of bamboo slices, thus reducing the damage of the tea leaves during the withering process. The swing rod 48 can drive the fixed ring 5 to swing and shake.

[0053] Specifically, in order to drive the support frame 54 to deflect so that the support frame 54 can stir the tea leaves after deflection, the outer surface of the fixed ring 5 is rotatably connected to the roller 6, and the outer surface of the roller 6 is rotatably connected to the driving ring 61 with a column, and a deflection plate 62 with a slide groove is fixedly installed at one end of the support frame 54, and the inner wall of the deflection plate 62 is slidably plugged into one end of the column of the driving ring 61.

[0054] Specifically, in order to drive the driving ring 61 to rotate, a driving arc groove 63 is opened on the inner wall of the screen assembly 33 , and one end of a column of the driving ring 61 is slidably plugged into the inner wall of the driving arc groove 63 .

[0055] Preferably, a detection plate 64 is fixedly mounted on the inner wall of the screen assembly 33, an industrial camera 65 is fixedly mounted on the outer surface of the detection plate 64, and a sensor assembly 66 is fixedly mounted on the outer surface of the detection plate 64. The sensor assembly 66 includes a temperature sensor, a humidity sensor, a laser scattering sensor and a gas sensor.

[0056] Through multiple sensors in the sensor group, a high-resolution industrial camera 65 is configured with an LED multi-band light source of 405nm / 530nm / 660nm / 850nm. The detection indicators include chlorophyll content 660nm reflectivity, polyphenol oxidase activity 405nm absorbance, and moisture content 850nm near-infrared absorbance. The laser scattering sensor uses a 650nm laser source and a photodiode array to measure the scattering pattern of light reflected from the surface of tea leaves. Feature extraction: Hurst index analysis of surface texture complexity. For unshaken leaves, H>0.7, which drops to 0.5-0.6 after moderate shaking. The gas sensor array is composed of a variety of gas-sensitive elements such as metal oxide semiconductors, conductive polymers, etc. Each sensor has cross-sensitivity to different gases, forming a unique response mode. The sampling system inhales gas samples through a dynamic gas path to ensure that the sensor is fully exposed to the gas to be tested. Some systems support automatic sampling and temperature control functions. Signal processing and pattern recognition use algorithms such as principal component analysis and artificial neural networks to convert sensor responses into recognizable "odor fingerprints" and compare them with the database to complete classification or quantitative analysis. Gas sample → sensor array response → signal preprocessing → pattern recognition → result output qualitative or quantitative, detect volatile organic compounds, linalool concentration, oolong tea characteristic aroma, and chlorophyll degradation rate to indicate fermentation progress.

[0057] Working principle: When it is necessary to perform the leaf shaking operation on the tea leaves, the tea leaves are poured into the screen assembly 33. The discharge port of the screen assembly 33 and the rotary drum 3 face upward, facilitating the entry of the tea leaves into the screen assembly 33. After the electric push rod 34 on the swing frame 21 is started, it pushes the screen assembly 33 to move within the rotating sleeve 31 and the rotary drum 3, causing the driving block 37 to disengage from the limiting ring 36, and separating the screen assembly 33 from the rotary drum 3. Then the rotating motor 35 is started, and through the cooperation of the synchronous belt and synchronous pulley, it drives the rotating sleeve 31 to rotate. The rotating sleeve 31 drives the screen assembly 33 and the telescopic rod 32 to rotate on the rotary drum 3. The discharge port of the screen assembly 33 deflects, and the roller rotates on the inner wall of the rotary drum 3. After the rotating motor 35 stops, the electric push rod 34 resets, enabling the driving block 37 to be inserted into the limiting ring 36. At the same time, the support frame 54 deflects, facilitating the stirring of the tea leaves inside the screen assembly 33. When the rotating motor 35 is started, the screen assembly 33 and the rotary drum 3 rotate synchronously, making the tea leaves stirred evenly and collide with each other to complete the preliminary leaf shaking. Meanwhile, the impurities in the tea leaves fall into the rotary drum 3 through the screen assembly 33. When the rotary drum 3 rotates and its discharge port faces downward, the impurities can fall off;

[0058] After the swing motor 2 on the bracket 1 is started, it can drive the swing frame 21 to rotate. The swing frame 21 can drive the rotary drum 3 to flip around the bracket 1, thereby completing the further leaf shaking of the tea leaves. After the electric push rod 34 pushes the screen assembly 33 to move, the driving arc groove 63 on the screen assembly 33 drives the driving ring 61 to rotate. After the driving ring 61 drives the deflection plate 62 to deflect, it drives the support frame 54 to deflect. Multiple support frames 54 distributed in a circular array can enclose a circle to form a leaf shaking sieve. When the swing motor 2 is started and the swing frame 21 rotates, it can drive the screen assembly 33 to be perpendicular to the ground;

[0059] Meanwhile, the deflection motor 47 starts, and the deflection motor 47 drives the connecting seat 46 to deflect on the driving rod 45, pulling the fixing ring 5 to tilt. The driving motor 4 starts, driving the driving magnetic ring 41 to rotate. The driving magnetic ring 41 drives the driven magnetic ring 44 to rotate. The driven magnetic ring 44 drives the transmission rod 43 to rotate. The transmission rod 43 drives the driving rod 45 on the connecting frame 42 to rotate through gear transmission. The driving rod 45 drives the swing rod 48 on the connecting seat 46 to rotate. The swing rod 48 swings on the universal coupling 49. The swing rod 48 drives the fixed shaft 56 to drive, so that the fixed shaft 56 drives the fixing ring 5 to tilt and swing. The fixing ring 5 drives the spherical connecting rod 51 to move up and down on the annular support 52, thereby driving the connected fixing ring 5 to tilt and deflect synchronously, and performing leaf shaking on the tea leaves located on the bamboo woven sieve plate 55 of the support frame 54. The degree of leaf shaking of the tea leaves is monitored by the sensor assembly 66 and the industrial camera 65, and the speed and method of leaf shaking are adjusted at any time. The sieve mesh assembly 33 can be driven by the swing frame 21 to flip, so that the tea leaves at the lower end are located at the upper end, and then leaf shaking is performed on the tea leaves at the lower end;

[0060] After the leaf shaking is completed, after the swing frame 21 rotates to make the rotating cylinder 3 parallel to the ground, the rotating motor 35 drives the rotating sleeve 31 to rotate. The rotating sleeve 31 drives the sieve mesh assembly 33 to rotate. After the discharge port of the sieve mesh assembly 33 is aligned with the discharge port of the rotating cylinder 3, the electric push rod 34 pushes the sieve mesh assembly 33 to move.
