Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tea making, in particular to automatic production equipment for refining tea with high cleanliness. Background Art
[0002] In traditional tea refining production, manual operation or semi-automated equipment is the mainstream. This method not only has low production efficiency and high labor intensity, but also makes it difficult to ensure quality consistency due to human factors. Tea is exposed to an open environment for a long time and is easily contaminated by impurities such as dust and hair, and cannot meet high cleanliness requirements. After the application of automation technology, although the production model has been improved, the existing automation equipment still has shortcomings. Its cleaning function is single and it is difficult to remove fine impurities. The process connection is not smooth, which can easily lead to tea accumulation and residue, increasing the risk of secondary pollution. In addition, there is a lack of effective cleanliness detection and monitoring, and the cleaning status cannot be controlled in real time, making it difficult to ensure that the product cleanliness meets the standards.
[0003] Chinese patent CN102813014B discloses an automated Keemun black tea refining production line, comprising a drying device, a stacking device, an iron removal device, a screening device, and a weighing device connected end to end. The tea leaves are first dried in the drying device and then conveyed to the stacking device. After being stacked in the stacking device, the tea leaves are conveyed to the iron removal device. After iron removal, the tea leaves are conveyed to the screening device for screening. After screening, the tea leaves are conveyed to the weighing device for weighing, and then packaged and stored. The advantages of the present invention are: the fully automatic Keemun black tea refining production line greatly improves the tea refining efficiency and greatly enhances the quality of the refined Keemun black tea.
[0004] During actual use, it was found that the production line had insufficient cleanliness assurance. On the one hand, it did not have a special tea dust removal process. Before the drum was used to extract the fragrance, the dust attached to the surface of the tea leaves could not be effectively removed. During the extraction process, the pores on the surface of the tea leaves were blocked by dust, which greatly reduced the effect of subsequent adsorption of floral fragrance and seriously affected the quality of the tea. On the other hand, the dust remaining on the conveyor belt could not be cleaned in time. As the tea leaves were continuously conveyed, dust was constantly mixed into the tea leaves, aggravating secondary pollution and making it difficult to meet the production requirements of high-cleanliness tea refining.

In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0024] Example 1 like Figures 1 to 3 As shown, this embodiment provides a high-cleanliness automatic tea refining production equipment. The first conveyor 100 includes: A conveying mechanism 1 is provided inside the machine body 1001, a dust collecting mechanism 2 is provided inside the machine body 1001 and is used to remove dust on the tea leaves, a cleaning mechanism 3 is provided below the conveying mechanism 1 and is used to remove dust on the conveyor belt, and an air drying mechanism 4 is provided below the conveying mechanism 1; The conveying mechanism 1 adopts intermittent transmission to convey tea leaves, the dust suction mechanism 2 disrupts the tea leaves by intermittent blowing to let the dust fall, and then removes the dust fallen on the tea leaves by negative pressure suction, the cleaning mechanism 3 removes the dust remaining on the conveying mechanism 1 by brushing, and the air-drying mechanism 4 removes the water remaining after the cleaning mechanism 3 brushes by hot air to prevent the residual water from affecting the subsequent tea leaves.
[0025] Further, if Figures 2 to 3 As shown, the conveying mechanism 1 includes: a driving member 101, which is used to intermittently drive a perforated conveyor belt 102. The air holes on the perforated conveyor belt 102 are used to cooperate with the dust collection mechanism 2 to remove dust on the tea leaves. A conveying push plate 103 is also provided on the perforated conveyor belt 102.
[0026] In this embodiment, by setting up a conveying mechanism 1, the function of intermittently conveying tea leaves is realized, thereby achieving the effect of controlling the tea leaf conveying rhythm and facilitating the dust collection mechanism 2 and other components to process the tea leaves; by cooperating with the air holes on the perforated conveyor belt 102 and the dust collection mechanism 2, the function of removing dust from the tea leaves is achieved, thereby achieving the effect of improving the cleanliness of the tea leaves; by cooperating with the perforated conveyor belt 102 and the conveying push plate 103, the function of pushing the tea leaves to move on the conveyor belt is achieved, thereby achieving the effect of ensuring the smooth transportation of the tea leaves.
[0027] In detail, when the driving member 101 is working, the output power causes the perforated conveyor belt 102 to make intermittent motion. The driving member 101 provides a stable driving force, driving the perforated conveyor belt 102 to start and stop periodically, so that the tea leaves can intermittently pause on the conveyor belt, so that the dust collection mechanism 2 has enough time to clean the dust from the tea leaves, ensuring the effectiveness of each cleaning. The air holes on the perforated conveyor belt 102 play an important role when the dust collection mechanism 2 is working. The dust collection mechanism 2 blows air to disrupt the tea leaves, and dust falls. At this time, the air holes allow air to pass through, so that the negative pressure generated by the dust collection mechanism 2 can absorb the dust dropped from the tea leaves through the air holes, thereby improving the efficiency of dust removal. The conveying push plate 103 is fixed on the perforated conveyor belt 102 and moves with the movement of the perforated conveyor belt 102. Its function is to push the tea leaves forward and avoid tea leaves piling up on the conveyor belt, thereby ensuring the smoothness of tea transportation and the continuity of the entire production process.
[0028] Further, if Figures 4 to 6 As shown, the dust collection mechanism 2 includes: A first blower 201, wherein the first blower 201 is provided on the machine body 1001; The blowing cavity 202 is evenly provided with a plurality of air outlet holes and is connected to the air outlet pipe of the first blower 201 to scatter tea leaves and remove dust; A dust suction chamber 203 is provided with a plurality of air inlet holes and is connected to the air inlet pipe of the first blower 201 for absorbing dust dropped from the tea leaves; A filter 204 is provided inside the dust collection chamber 203; The isolation box 205 is arranged inside the body 1001 to prevent the tea leaves from being blown away.
[0029] In this embodiment, by setting up a dust suction mechanism 2, the function of blowing air into the blowing chamber 202 and spraying it out from its air outlet to scatter the tea leaves and make the dust fall off, thereby achieving the effect of making it easier to remove the dust on the tea leaves; and the negative pressure is used to absorb the dust that falls near the air inlet of the dust suction chamber 203.
[0030] In detail, after the first blower 201 is started, a strong airflow is generated. The airflow enters the blowing chamber 202 along the air outlet pipe. The air outlet holes evenly distributed on the blowing chamber 202 allow the airflow to be evenly ejected. These airflows impact the tea leaves, breaking them up and causing the dust originally attached to the tea leaves to fall off due to external force. When the first blower 201 is working, a negative pressure environment is formed in the dust suction chamber 203. The outside air is sucked into the dust suction chamber 203 from the air inlet hole of the dust suction chamber 203 with the fallen dust. The design of the air inlet hole can guide the dust into the dust suction chamber 203, and cooperate with the suction force of the first blower 201. , efficiently absorb dust, the filter 204 is located inside the dust suction chamber 203, when dust enters the dust suction chamber 203 with the air flow, the filter 204 can block the dust from passing through and only allow air to pass through, avoiding dust from circulating inside the equipment, ensuring the cleanliness of the equipment operating environment, and preventing dust from re-attaching to the tea leaves. The isolation box 205 is set in the body 1001. When the blowing chamber 202 blows away the tea leaves, the isolation box 205 can act as a barrier to prevent the tea leaves from being blown out of the normal processing area, avoiding the waste of tea leaves and pollution of the environment around the equipment, and ensuring the continuity and stability of the production process.
[0031] Further, if Figures 7 to 12 As shown, the cleaning mechanism 3 includes: A longitudinal shaking assembly 31 is provided inside the machine body 1001 and is used to clean the perforated conveyor belt 102 by reciprocating motion; A lifting assembly 32 is provided on the machine body 1001 and is used to allow the bristles to approach the perforated conveyor belt 102 to clean the surface of the perforated conveyor belt 102; A lateral expansion component 33 is provided on the longitudinal shaking component 31 and is used to allow the bristles on both sides to approach the conveying push plate 103, thereby cleaning the dust on the conveying push plate 103; The water spray component 34 is arranged on the body 1001 and is used to spray water to wet the perforated conveyor belt 102 and the conveying push plate 103 before the brush is cleaned, and spray water again after cleaning to remove dust, so that the cleaning is more thorough.
[0032] In this embodiment, through the reciprocating motion of the longitudinal shaking component 31, in conjunction with the perforated conveyor belt 102, the function of cleaning different positions of the perforated conveyor belt 102 is achieved, thereby achieving the effect of comprehensively cleaning the perforated conveyor belt 102; through the lifting component 32, the bristles are brought close to the perforated conveyor belt 102, thereby achieving the function of cleaning the surface of the perforated conveyor belt 102, thereby achieving the effect of effectively removing dust from the surface of the perforated conveyor belt 102; through the horizontal expansion component 33, the bristles are brought close to the conveying push plate 103, thereby achieving the function of cleaning the dust on the conveying push plate 103, thereby achieving the effect of ensuring the cleanliness of the conveying push plate 103 and preventing dust from mixing into subsequent tea leaves; through the water spraying component 34, water is sprayed before and after cleaning, in conjunction with the brush cleaning, thereby achieving the function of more thorough dust removal, thereby achieving the effect of improving cleanliness.
[0033] Further, if Figure 8 As shown, the longitudinal shaking component 31 includes: A sliding rod 311, the sliding rod 311 is arranged inside the body 1001; A sliding seat 312 , the sliding seat 312 being slidably disposed on the sliding rod 311 ; A first motor 313, which is disposed on the machine body 1001; a rotating disk 314 , the rotating disk 314 being drivingly connected to an output shaft of the first motor 313 ; The reciprocating push plate 315 is rotatably connected to the sliding seat 312 and the rotating disk 314 respectively, and is used to drive the sliding seat 312 to reciprocate.
[0034] In this embodiment, a longitudinal shaking component 31 is provided, in which the driving turntable 314 rotates continuously, thereby providing a power source for driving the sliding seat 312 to move back and forth, ensuring that the cleaning action can be carried out continuously; and the function of converting the circular motion of the turntable 314 into the reciprocating linear motion of the sliding seat 312 is realized, so that the cleaning components connected to the sliding seat 312 can clean different positions below the perforated conveyor belt 102, thereby achieving the effect of fully cleaning the perforated conveyor belt 102.
[0035] In detail, after the first motor 313 is powered on and started, it outputs stable rotational power, and its output shaft drives the turntable 314 connected to it to rotate continuously. The turntable 314 performs circular motion driven by the first motor 313, and the edge of the turntable 314 is rotationally connected to the reciprocating push plate 315. When the turntable 314 rotates, its circular motion is transmitted to the sliding seat 312 through the reciprocating push plate 315. Since the other end of the reciprocating push plate 315 is rotationally connected to the sliding seat 312, this special connection method cleverly converts the circular motion of the turntable 314 into a reciprocating linear motion of the sliding seat 312, so that the sliding seat 312 can move back and forth under the perforated conveyor belt 102 according to the set trajectory, thereby driving the cleaning component to clean different areas of the perforated conveyor belt 102 to ensure comprehensive cleaning without omissions.
[0036] Further, if Figures 8 and 9 As shown, the lifting assembly 32 includes: A fixed column 321 , the fixed column 321 is disposed on the sliding seat 312 ; A lifting plate 322 slidably disposed on the fixing column 321 ; A fixing block 323 symmetrically disposed on the lifting plate 322 ; A sliding rod 324 , the sliding rod 324 being disposed on the fixing block 323 ; A slider 325 , the slider 325 being slidably disposed on the sliding rod 324 ; The cylinder 326 has a push rod connected to the slider 325 .
[0037] In this embodiment, by setting up a lifting component 32, the function of separating the reciprocating motion of the longitudinal shaking component 31 from the fixed setting of the cylinder 326 is achieved, so that when the longitudinal shaking component 31 drives the cleaning component to reciprocate, the cylinder 326 does not need to follow the movement, thereby reducing the number of moving parts and reducing the energy consumption of the equipment; and the function of guiding the vertical movement of the lifting plate 322 is achieved, thereby ensuring that the bristles can accurately approach or move away from the perforated conveyor belt 102, thereby improving the stability of the cleaning effect; and the function of accurately controlling the height of the lifting plate 322 is achieved, thereby adjusting the contact pressure between the bristles and the perforated conveyor belt 102 according to different cleaning requirements, thereby improving the adaptability of the cleaning effect.
[0038] In detail, when the longitudinal rocking assembly 31 drives the sliding seat 312 to perform reciprocating motion, the fixed block 323 fixed on the lifting plate 322 moves synchronously therewith, and the sliding rod 324 is connected to the lifting plate 322 through the fixed block 323, so the sliding rod 324 also performs reciprocating motion. At this time, the slider 325 slides on the sliding rod 324. Since the slider 325 is connected to the top rod of the cylinder 326, and the cylinder 326 is fixedly arranged on the body, this structure prevents the reciprocating motion of the longitudinal rocking assembly 31 from being transmitted to the cylinder 326, thereby preventing the cylinder 326 from participating in the reciprocating motion, reducing the mass and inertia of the moving parts, and reducing the energy consumption and wear of the equipment. When the cylinder 326 is working, the extension and retraction of its top rod directly drives the slider 325 to move on the sliding rod 324. The movement of the slider 325 is transmitted to the lifting plate 322 through the fixed block 323 and the sliding rod 324, so that the lifting plate 322 can move up or down in the vertical direction along the fixed column 321. This structural design enables the cylinder 326 to accurately control the height position of the lifting plate 322, thereby adjusting the distance and contact pressure between the bristles installed on the lifting plate 322 and the perforated conveyor belt 102 to adapt to different cleaning needs.
[0039] Further, if Figures 10 and 11 As shown, the horizontal expansion component 33 includes: A position-limiting telescopic rod 331 symmetrically disposed on the sliding seat 312 ; A top plate 332 , the top plate 332 being disposed on the top rod of the position-limiting telescopic rod 331 ; A sliding plate 333 having a groove therein and slidably disposed on the top plate 332; Brush bristles 3331 , the brush bristles 3331 being disposed on the top and one side of the sliding plate 333 ; A fixing bolt 334 , the fixing bolt 334 being disposed on the sliding plate 333 ; A tension spring 335 , the tension spring 335 being used to connect the fixing bolt 334 ; The rotatable connecting plate 336 has one end rotatably disposed on the sliding plate 333 , and the other end rotatably disposed on the lifting plate 322 .
[0040] In this embodiment, the function of providing a stable support platform for the sliding plate 333 is achieved through the lateral expansion component 33, thereby ensuring that the sliding plate 333 can move laterally on a stable basis, so that the bristles 3331 can better contact the conveying push plate 103; secondly, the function of adjusting the lateral position of the sliding plate 333 is achieved, so that the bristles 3331 can be close to or away from the conveying push plate 103, meeting the needs of cleaning dust at different positions of the conveying push plate 103.
[0041] The cam 331 is provided with a screwdriver to move the handle 332 to the left and right of the handle 333. The cam 332 is provided with a screwdriver to move the handle 333 to the left of the handle 333. The cam 332 is provided with a screwdriver to move the handle 333 to the left of the handle 333. The cam 332 is provided with a screwdriver to move the handle 333 to the left of the handle 333. The cam 332 is provided with a screwdriver to move the handle 333 to the left of the handle 333. One end of the rotating connecting plate 336 is rotatably connected to the sliding plate 333, and the other end is rotatably connected to the lifting plate 322. When the lifting plate 322 rises, it drives the rotating connecting plate 336 to rotate, which in turn drives the sliding plate 333 to move laterally on the top plate 332, so that the bristles 3331 are close to the conveying push plate 103. When the lifting plate 322 descends, the rotating connecting plate 336 rotates in the opposite direction, and the sliding plate 333 moves in the opposite direction accordingly. This connection method utilizes the lifting and lowering movement of the lifting plate 322 to achieve automatic lateral adjustment of the sliding plate 333, reducing manual intervention and improving cleaning efficiency. One end of the tension spring 335 is connected to the fixing bolt 334, which is provided on the sliding plate 333. When the lifting plate 322 descends and the sliding plate 333 needs to be reset, the tension spring 335 contracts, applying a pulling force to the sliding plate 333, so that the sliding plate 333 can quickly return to its initial position and prepare for the next cleaning cycle. The provision of the tension spring 335 ensures the continuity and stability of the movement of the sliding plate 333 and prevents the sliding plate 333 from moving randomly without external force.
[0042] Further, if Figure 9 and Figure 12 As shown, the water spray assembly 34 includes: Water pump 341; a telescopic tube 342 , the telescopic tube 342 being in communication with the water outlet of the water pump 341 ; a water delivery pipe 343 , the water delivery pipe 343 being in communication with the telescopic pipe 342 ; A rotating water spray head 344 , the rotating water spray head 344 is rotatably disposed on the water delivery pipe 343 ; a water inlet pipe 345 , the water inlet pipe 345 being connected to the water inlet of the water pump 341 ; A water storage barrel 346, wherein the water inlet pipe 345 extends to the bottom of the water storage barrel 346; A drainage trough plate 347 is provided at the bottom of the housing 1001 and has a drainage port; The water baffle 348 is arranged inside the body 1001 and located in the middle of the perforated conveyor belt 102, and is used to block the air holes of the perforated conveyor belt 102 to prevent water from wetting the tea leaves above.
[0043] In this embodiment, by setting up a water spray assembly 34, the function of extracting water from the water storage barrel 346 and pressurizing it to the rotating water spray head 344 is achieved, thereby achieving the effect of providing sufficient water flow for cleaning the perforated conveyor belt 102 and the conveying push plate 103.
[0044] In detail, after the water pump 341 is started, the water at the bottom of the water storage barrel 346 is sucked in through the water inlet pipe 345, the water pump 341 pressurizes the sucked water, and then discharges the water into the telescopic tube 342 through the water outlet. The telescopic tube 342 is connected to the water pipe 343. When other parts of the cleaning mechanism move, the telescopic tube 342 can stretch or shrink according to actual conditions. The rotating water spray head 344 is rotatably set on the water pipe 343. When water flows through, the impact force of the water flow will cause the rotating water spray head 344 to rotate around the connection point with the water pipe 343. This rotation enables water to be sprayed at different angles on the perforated conveyor belt 102 and the conveying push plate 103. Compared with fixed-angle water spraying, the cleaning coverage is greatly expanded, more areas can be cleaned, and the cleaning effect is effectively improved.
[0045] The drainage trough plate 347 is installed at the bottom of the machine body 1001. The sewage after cleaning the perforated conveyor belt 102 and the conveying push plate 103 will fall onto the drainage trough plate 347. The drainage port on the drainage trough plate 347 can discharge the sewage out of the equipment in time to avoid sewage accumulation inside the equipment. The water baffle 348 is set in the middle of the perforated conveyor belt 102. When the rotating water spray head 344 sprays water for cleaning, the water baffle 348 blocks the air holes of the perforated conveyor belt 102. In this way, the cleaning water will not penetrate into the tea leaves above through the air holes, preventing the tea leaves from being wetted by water and affecting the quality, thereby ensuring the dryness and quality of the tea leaves.
[0046] Further, if Figures 13 and 14 As shown, the air-drying mechanism 4 includes: A telescopic hair dryer 401 is provided on the body 1001 and has an inclined air outlet at one end thereof for blowing away water; A second motor 402 , the second motor 402 is mounted on the machine body 1001 ; a screw rod 403 , the screw rod 403 being drivingly connected to the output shaft of the second motor 402 ; A lead screw 404, which is provided on the telescopic hair dryer 401 and is threadably engaged with the lead screw 403; A second blower 405, the second blower 405 is provided on the machine body 1001; The heating chamber 406 is connected to the air outlet of the telescopic hair dryer 401 and the air outlet of the second blower 405 respectively.
[0047] In this embodiment, by setting up the air-drying mechanism 4, the function of driving the screw rod 403 to rotate is realized, thereby providing power for the linear movement of the telescopic hair dryer 401, so that the telescopic hair dryer 401 can be telescopically moved along the axial direction of the screw rod 403, and the position of the air outlet can be adjusted to realize the function of targeted drying at different positions and angles, thereby improving the air-drying efficiency and effect.
[0048] Specifically, after the second motor 402 is started, its output shaft drives the screw 403 connected thereto to rotate at high speed. When the screw 403 rotates, the screw 404, which is threadedly engaged with the screw 403, moves linearly along the axial direction of the screw 403. Since the screw 404 is provided on the telescopic hair dryer 401, the telescopic hair dryer 401 will extend and retract synchronously with the movement of the screw 404. When the second blower 405 is working, it sucks in the outside air, pressurizes it and sends it into the heating chamber 406. The strong airflow provided by the second blower 405 ensures that there is enough air entering the heating chamber 406 for heating. After the air is heated in the heating chamber 406, hot air is formed. The hot air enters the telescopic hair dryer 401 through the pipe and is blown out from its inclined air outlet. The heating effect of the heating chamber 406 on the air increases the temperature of the wind. The hot air can accelerate the evaporation rate of moisture, thereby more effectively drying the perforated conveyor belt 102 and the conveying push plate 103. The telescopic design of the telescopic hair dryer 401 enables it to adjust the position of the air outlet according to actual needs, and the inclined air outlet allows the hot air to be blown to the surface to be dried at a certain angle. This design can avoid the problem of hot air blowing directly vertically to the surface, causing moisture splashing or uneven drying, and can more effectively blow away moisture and accelerate evaporation, thereby improving the efficiency and effect of air drying.
[0049] Example 2 like Figure 1 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: An automatic production equipment for refining tea with high cleanliness also includes: a first elevator 200 for raising the height of tea leaves, a drum heating device 300 using segmented heating, a second conveyor 400 for conveying tea leaves, a second elevator 500 for raising the height of tea leaves, and a cooling device 600 for cooling tea leaves.
[0050] In this embodiment, the first elevator 200 is used to lift the tea leaves to a certain height, thereby facilitating subsequent processing of the tea leaves, and then conveying the tea leaves to the drum heating device 300, so that the entire production process can be smoothly connected. The drum heating device 300 with segmented heating is used to heat the tea leaves in segments under controlled temperature, thereby accurately activating the surface pores of the tea leaves according to the characteristics of the tea leaves at different stages, while promoting the Maillard reaction of tea polyphenols to form a stable aroma complex, thereby improving the quality of the tea leaves. The second conveyor 400 is used to convey the tea leaves processed by the drum heating device 300, and then conveying the tea leaves to the subsequent second elevator 500, thereby ensuring the continuity of the production process. The second elevator 500 is used to lift the tea leaves again, thereby meeting the tea feeding height requirements of the subsequent cooling device 600, ensuring the smooth cooling operation. The cooling device 600 is used to cool the heated tea leaves, thereby preventing the quality of the tea leaves from being affected by continuous high temperature and allowing the tea leaves to reach a suitable temperature for storage or further processing.
[0051] It should be noted that when the segmented heating drum heating device 300 is started, each heating section works according to the preset program. In the 90°C preheating stage, the heating element starts to heat up, causing the temperature inside the drum to gradually rise to 90°C. The tea leaves roll slowly in the drum and are heated evenly, initially activating the surface pores. After 5 minutes, it enters the 95°C main processing stage. At this time, the temperature rises, and the tea polyphenols begin to undergo the Maillard reaction, generating pyrazine substances and combining with ester aroma molecules. After 10 minutes, it enters the 100°C finishing stage, which lasts for 2 minutes, further strengthening the reaction, allowing the tea leaves to fully absorb the aroma and improve the quality.
[0052] When the cooling device 600 is working, the internal negative pressure heat dissipation structure starts to operate, and the tea leaves entering the cooling device 600 are evenly spread on the cooling platform. The negative pressure absorbs the heat of the air around the tea leaves, accelerating the heat dissipation, and the temperature of the tea leaves is quickly reduced to a suitable temperature, ensuring that the quality of the tea leaves is not affected by high temperature. Refining process: Loading → round sieve (two openings) → color sorting → hair removal → drum sterilization (selective passing) → cooling → drum stacking → round sieve machine screening → X-ray inspection.
[0053] Working steps Start the first conveyor 100, and the driving part 101 of the conveying mechanism 1 intermittently drives the perforated conveyor belt 102 and the push plate to convey the tea leaves. The first blower 201 of the dust suction mechanism 2 blows air into the blowing chamber 202 to break up the tea leaves and remove dust. The dust is then adsorbed by the dust suction chamber 203, filtered by the filter screen 204, and the isolation box 205 prevents the tea leaves from being blown away. During cleaning, the water spraying component 34 sprays water, the lifting component 32 makes the bristles close to the conveyor belt, the longitudinal shaking component 31 drives the bristles to brush longitudinally, and the transverse expansion component 33 allows the bristles to clean the push plate. After cleaning, water is sprayed again, and the water baffle 348 prevents the tea leaves from being wetted by water. The sewage is discharged through the drainage trough plate 347. Finally, the second motor 402 of the air-drying mechanism 4 drives the screw rod 403 to move the telescopic hair dryer 401, and the second blower 405 sends hot air through the heating chamber 406 and blows it out from the air outlet to dry the conveyor belt.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
