The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order; the orientation or positional relationship indicated by the terms "inner", "outer", "left", "right" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present invention provides a tea drying device, as Figure 1-10 shown. The tea drying device includes: a bracket 1 and a bin 2 provided on the bracket 1 for drying tea; a perforated plate 3 installed in the bin 2 for guiding air; a spreading rod 4 rotatably installed in the bin 2 for spreading tea; an air inlet pipe 5 installed on one side of the bin 2; a heating mechanism used in conjunction with the bin 2 to provide heat source for the bin 2, the heating mechanism includes a hot air furnace 6, a hot air blower 7 and a hot air bag 8, the hot air furnace 6 and the hot air blower 7 are connected to the hot air bag 8 through an air duct, and the hot air bag 8 is connected to the air inlet pipe 5 through an air duct; a collection mechanism provided above the bin 2 for collecting tea fragments.

[0022] In this embodiment, during operation, the heating mechanism generates hot air through the hot air furnace 6 and the hot air blower 7, and then sends the hot air into the hot air bag 8. The hot air bag 8 then sends the hot air into the air inlet pipe 5 of the bin 2 through the air duct. The hot air is evenly blown onto the tea through the guidance of the perforated plate 3 in the bin 2. At the same time, the spreading rod 4 rotates in the bin 2 to spread the tea in a rotating manner, ensuring that the tea is evenly distributed in the bin 2 and improving the drying efficiency. In addition, the device can be configured with multiple bins 2, and the heating mechanism can supply heat to multiple bins 2 simultaneously, enabling multiple bins 2 to dry tea simultaneously. Finally, the tea fragments generated during the drying process will be collected by the collection mechanism; Secondly, since Pu-erh tea needs to avoid "stuffy drying" during the drying process (that is, in a closed environment, the hot and humid air cannot be discharged in time, resulting in the tea leaves getting damp or over-fermenting), when drying Pu-erh tea, the bin cover 16 needs to be far away from the bin 2 to keep the bin 2 in an open state, ensuring that the hot and humid air can naturally escape and preventing steam accumulation from affecting the tea quality. Secondly, the open design combined with the dynamic circulation of hot air can not only maintain the uniformity of the drying temperature but also meet the technological requirements of "ventilated slow drying" for Pu-erh tea. At the same time, through the air guiding function of the perforated plate 3, the hot air uniformly penetrates the tea layer from the bottom of the bin 2, and the hot and humid air naturally discharges upward, avoiding local stuffiness. The rotating material spreading rod 4 continuously turns the tea leaves, further preventing the tea leaves from stacking and sticking together, ensuring that each tea leaf fully contacts the hot air and improving the drying uniformity.

[0023] In addition, this drying device adopts a multi-functional design and can flexibly adjust the drying mode according to the technological requirements of different tea varieties: Pu-erh tea (ventilated slow drying mode): Open drying: Remove the bin cover 16 of the bin 2 to keep it ventilated, avoid the accumulation of heat and humidity, ensure the natural slow drying of the tea leaves, and retain the flavor and active substances of Pu-erh tea.

[0024] Gentle hot air: Adopt a moderate wind force and cooperate with the slow turning of the material spreading rod 4 to make the tea leaves evenly heated without losing the moisture balance.

[0025] Other tea varieties (efficient drying mode): Closed drying: Cover the bin cover 16 of the bin 2 to form a closed environment, reduce heat loss, and improve the thermal energy utilization rate.

[0026] Enhanced wind force: Increase the air supply volume through the hot air blower 7 to enhance the penetration of the hot air and accelerate the dehydration of the tea leaves, which is suitable for tea varieties such as green tea and black tea that require rapid shaping.

[0027] High-temperature adaptation: The temperature of the hot air furnace 6 can be adjusted according to the requirements of the tea variety. For example, green tea requires a higher temperature for rapid fixation, while oolong tea requires segmented temperature control.

[0028] Through the rotating material spreading of the material spreading rod 4 and the air guiding function of the perforated plate 3, the hot air can be evenly blown onto the tea leaves, ensuring that the tea leaves are evenly distributed in the bin 2, thereby improving the drying efficiency. Through the cooperation of the hot air furnace 6 and the hot air blower 7, stable and uniform hot air can be generated, avoiding the problem of uneven temperature distribution caused by the traditional electric heating wire heating method and improving the quality of tea leaf drying.

[0029] In a further preferred embodiment of the present invention, a vibration motor 9 is fixedly installed at the bottom of the bin 2, a connecting frame 10 is installed on the bracket 1, the connecting frame 10 is hinged to the bin 2, and a first shock absorption assembly 11 is installed at the bottom of the connecting frame 10.

[0030] In this embodiment, when the vibration motor 9 is started, it generates a vibration force, which is transmitted to the silo 2, and then the tea leaves in the silo 2 are vibrated. This vibration helps to loosen and turn over the tea leaves, enabling the tea leaves to be more evenly distributed in the silo 2 during the drying process, thereby improving the drying efficiency. At the same time, the first shock-absorbing component 11 at the bottom of the connecting frame 10 will absorb the vibration force generated by the vibration motor 9, reducing the impact of the vibration on the bracket 1 and the entire device, and ensuring the stable operation of the device. By adding the vibration motor 9, the tea leaves can be more evenly distributed in the silo 2 during the drying process, avoiding the accumulation and adhesion of the tea leaves, and thus improving the drying efficiency.

[0031] In a further preferred embodiment of the present invention, a driving mechanism for driving a group of material scattering rods 4 to rotate is installed on the silo 2. The driving mechanism includes: first sprockets 12 fixedly sleeved on the rotating shafts of a group of the material scattering rods 4; a first chain 13 sleeved on a group of the first sprockets 12, and the first chain 13 meshes with a group of the first sprockets 12; a servo motor 14 fixedly installed on one side of the silo 2 for driving a group of the material scattering rods 4 to rotate, and the output shaft of the servo motor 14 is fixedly connected to the rotating shaft of any one of the material scattering rods 4; a first protective box 15 fixedly installed on one side of the silo 2 for protecting the first sprockets 12, the first chain 13 and the servo motor 14.

[0032] In this embodiment, when the servo motor 14 is started, its output shaft drives the material scattering rod 4 fixedly connected thereto to rotate. Since the first sprockets 12 are fixedly sleeved on the rotating shafts of this group of material scattering rods 4, and these first sprockets 12 are meshed through the first chain 13, when one material scattering rod 4 rotates, it will drive other material scattering rods 4 to rotate synchronously through the transmission of the first sprockets 12 and the first chain 13. In this way, a group of material scattering rods 4 can rotate synchronously to perform the material scattering process on the tea leaves, ensuring that the tea leaves can be evenly distributed in the silo 2 during the drying process.

[0033] At the same time, the setting of the first protective box 15 can effectively protect components such as the first sprockets 12, the first chain 13 and the servo motor 14, avoiding their interference and damage by the external environment, and ensuring the stable operation of the driving mechanism. By driving a group of material scattering rods 4 to rotate synchronously by the servo motor 14, the material can be scattered more quickly and evenly, enabling the tea leaves to be more fully in contact with the hot air during the drying process, thereby improving the drying efficiency. Since a group of material scattering rods 4 can rotate synchronously, there is no need to equip each material scattering rod 4 with a driving motor, thus saving energy and cost.

[0034] In a further preferred embodiment of the present invention, a silo cover 16 is installed on the silo 2. An electric telescopic rod 17 is installed on one side of the bracket 1. A connecting plate 18 is fixedly installed on the electric telescopic rod 17. A steel wire rope 19 is fixedly installed at the bottom of the connecting plate 18, and the bottom end of the steel wire rope 19 is fixedly connected to the top of the silo cover 16. A counterweight 49 is installed on the connecting plate 18.

[0035] In this embodiment, when it is necessary to open the silo cover 16, first start the electric telescopic rod 17 to drive the connecting plate 18 to slide upward. Since the steel wire rope 19 is fixedly installed at the bottom of the connecting plate 18 and the bottom end of the steel wire rope 19 is fixedly connected to the top of the silo cover 16, the upward sliding of the connecting plate 18 will drive the silo cover 16 to move upward together, thus moving away from the opening of the silo 2. At the same time, the counterweight 49 on the connecting plate 18 is arranged opposite to the silo cover 16, which can effectively reduce the torque generated during the operation of the electric telescopic rod 17, making the operation of the entire hoisting system more stable and labor-saving. Through the hoisting system of the electric telescopic rod 17 and the steel wire rope 19, the automatic opening and closing of the silo cover 16 are realized, improving the convenience of operation. Through the setting of the counterweight 49, the torque generated during the operation of the electric telescopic rod 17 is effectively reduced, making the operation of the entire hoisting system more stable and avoiding the instability or damage of the system caused by excessive torque.

[0036] In a further preferred embodiment of the present invention, a cover plate 20 is hinged to the top of the silo cover 16. A limiting frame 21 for limiting the cover plate 20 is fixedly installed on the top of the silo cover 16. A connecting box 22 is fixedly installed on the top of the cover plate 20. A return spring 23 is fixedly installed in the connecting box 22. One end of the return spring 23 is provided with a roller 24, and the roller 24 is connected to the limiting frame 21.

[0037] In this embodiment, when it is necessary to fix the cover plate 20, first press the roller 24 to compress the return spring 23. At this time, the roller 24 will slide and contact one side of the connecting box 22. Then, close the cover plate 20 to make the roller 24 rotate to one side of the limiting frame 21. When the roller 24 contacts the limiting frame 21, release the roller 24, and the return spring 23 will release the elastic potential energy it stores, pushing the roller 24 to snap into the limiting frame 21, thereby realizing the fixation of the cover plate 20. Through the design of the roller 24 and the return spring 23, the rapid fixation and release of the cover plate 20 are realized, improving the convenience of operation. Through the elastic action of the return spring 23, the roller 24 can be firmly snapped into the limiting frame 21, thereby enhancing the fixation stability of the cover plate 20.

[0038] In a further preferred embodiment of the present invention, a sloping plate 25 is fixedly installed on the top of the bin cover 16, and the sloping plate 25 is made of a metal material. A magnet block 26 is installed on the top of the cover plate 20, and the magnet block 26 is adapted to the sloping plate 25.

[0039] In this embodiment, when it is necessary to open the cover plate 20, according to the previous operation method, through the cooperation of the roller 24 and the return spring 23, the cover plate 20 is released from the limit frame 21 and rotated to the open position. At this time, due to the magnetic effect of the magnet block 26, it will be adsorbed on the metal sloping plate 25, thereby fixing the cover plate 20. This fixing method is simple and effective. Through the adsorption between the magnet block 26 and the sloping plate 25, the cover plate 20 can be automatically fixed on the sloping plate 25 after being opened, without additional fixing operations, improving the convenience of operation.

[0040] In a further preferred embodiment of the present invention, a cylinder 27 is hinged to the support rod of the bracket 1, and a connecting spring 28 is hinged to the bottom of the bin 2. The bottom end of the connecting spring 28 is fixedly connected to the output rod of the cylinder 27.

[0041] In this embodiment, when it is necessary to adjust the inclination angle of the bin 2, the cylinder 27 is started to make its output rod extend and retract. When the output rod extends, through the transmission of the connecting spring 28, a downward moment is generated on the bin 2, causing the bottom of the bin 2 to tilt downward. When the output rod retracts, the bottom of the bin 2 is lifted upward. By adjusting the extension and retraction length of the output rod of the cylinder 27, the inclination angle of the bin 2 can be controlled, so as to facilitate the subsequent cleaning of the dried tea leaves. Through the adjustment of the inclination angle of the bin 2 by the cylinder 27, the dried tea leaves are piled up on one side of the bin 2, and it is easier to take them out of the bin 2, improving the convenience of material taking.

[0042] In a further preferred embodiment of the present invention, the collection mechanism includes: a collection box 29 arranged above the bin cover 16 for collecting tea leaf fragments; a second shock absorption assembly 30 fixedly installed on the collection box 29 and the bin cover 16; a guiding hopper 31 fixedly installed in the collection box 29; a collection bag 32 installed on the discharge pipe of the guiding hopper 31 for centrally collecting fragments; a collection hopper 33 fixedly installed on the top of the bin cover 16 for exhausting air from the bin 2, and the pipe of the collection hopper 33 is fixedly connected to the top of the collection box 29; a separation net 34 for intercepting tea leaves is installed in the collection hopper 33.

[0043] In this embodiment, during the tea drying process, the heating mechanism provides heat source to the bin 2. The used hot air carries tea scraps and is discharged into the collection box 29 through the collection hopper 33. Due to the presence of the partition net 34, the tea is intercepted in the bin 2, while the gas with scraps continues to enter the collection box 29. In the collection box 29, the gas and scraps are guided by the guiding hopper 31 and flow towards the discharge pipe. At this time, the collection bag 32 is located below the discharge pipe and can collect the scraps centrally. Finally, the gas after purification treatment is discharged through the air outlet of the collection box 29. Through the design of the collection mechanism, tea scraps can be effectively collected, preventing them from mixing into the finished tea, thereby improving the quality of the tea. The gas with scraps is discharged after being filtered by the collection bag 32, reducing environmental pollution. The addition of the second shock-absorbing component 30 reduces the impact of vibration on the collection box 29 and enhances the stability of the collection box 29.

[0044] In a further preferred embodiment of the present invention, a limiting plate 35 is fixedly installed in the collection box 29. A filter screen 36 for filtering tea dust is slidably installed on the limiting plate 35. A support rod 37 is fixedly installed at the top of the collection box 29. The support rod 37 is located above the filter screen 36 and is used to support the collection bag 32.

[0045] In this embodiment, during the tea drying process, the heating mechanism provides heat source to the bin 2. The used hot air carries tea scraps and dust and is discharged into the collection box 29 through the collection hopper 33. The tea scraps are collected by the collection bag 32, while the gas containing dust continues to pass through the filter screen 36. Due to the filtering effect of the filter screen 36, the dust is intercepted on the filter screen 36, and the clean gas is discharged after passing through the filter screen 36. At the same time, the support rod 37 provides stable support for the collection bag 32, preventing it from contacting the cleaning brush 39 and ensuring the normal operation of the collection bag 32. The addition of the filter screen 36 can effectively filter tea dust, ensuring that the dust is not discharged into the air, thereby improving the air quality. The filtering effect of the filter screen 36 reduces the erosion of the equipment by dust and extends the service life of the equipment. The support rod 37 provides stable support for the collection bag 32, ensuring that the collection bag 32 can efficiently collect tea scraps. The filter screen 36 is slidably installed on the limiting plate 35, making cleaning and maintenance more convenient. By adding components such as the limiting plate 35, the filter screen 36, and the support rod 37, the overall performance of the equipment is further enhanced, and the market competitiveness of the tea drying device is improved.

[0046] In a further preferred embodiment of the present invention, a plurality of air outlets are provided on the collection box 29, and dust-proof nets 38 are installed in all of the plurality of air outlets. A hook is fixedly installed at the bottom of the bin cover 16, and a lock catch is fixedly installed on one side of the bin 2. The lock catch is adapted to the hook.

[0047] In this embodiment, the filtered clean gas is discharged through multiple air vents on the collection box 29, while the dust-proof net 38 further blocks the possibly remaining dust, ensuring that the discharged gas meets the environmental protection requirements. At the same time, the bin cover 16 is firmly locked on the bin 2 through the cooperation of the hook and the lock, guaranteeing the smooth progress of the drying process. Through the uniform distribution of the multiple air vents, the hot gas is discharged more evenly, improving the stability of the equipment. The design of components such as the dust-proof net 38 and the filter screen 36 makes cleaning and maintenance more convenient, reducing the maintenance cost.

[0048] To further improve the usage effect of this device, in addition to the above solution, this solution also has the following embodiments: In another embodiment of the present invention, a cleaning mechanism for cleaning the dust on the filter screen 36 is provided on the collection box 29. The cleaning mechanism includes: two groups of cleaning brushes 39 that are rotatably installed in the collection box 29 for cleaning the dust on the filter screen 36; second sprockets 40 respectively fixedly sleeved on the two groups of cleaning brushes 39; two second chains 41 respectively sleeved on the two groups of second sprockets 40; a set of connecting gears 42 respectively arranged on one side of the collection box 29 and any one of the second sprockets 40, and the two groups of second connecting gears 42 are meshed with each other, and a linkage mechanism for synchronously driving the connecting gear 42 and the first sprocket 12 to rotate is arranged on the rotating shaft of any one of the connecting gears 42 and the first sprocket 12.

[0049] In this embodiment, during the tea drying process, when the first sprocket 12 rotates, through the setting of the linkage mechanism, the connecting gear 42 rotates synchronously with the first sprocket 12. The rotation of the connecting gear 42 drives the second sprocket 40 meshed with it to rotate. Then, through the transmission of the second chain 41, the two groups of cleaning brushes 39 rotate synchronously and rotate in opposite directions. This rotation in opposite directions can more effectively clean the dust on the filter screen 36, making the dust accumulate in the V-shaped inner cavity of the filter screen 36, ensuring the smooth ventilation of the filter screen 36. Through the setting of the linkage mechanism, the synchronous rotation of the cleaning brush 39 and the first sprocket 12 is realized, thereby improving the cleaning efficiency. Through the two groups of cleaning brushes 39 rotating in opposite directions, the dust on the filter screen 36 can be more effectively cleaned, ensuring the smooth ventilation of the filter screen 36. The design of the automatic cleaning mechanism reduces the frequency of manual cleaning and lowers the maintenance cost.

[0050] In another embodiment of the present invention, the linkage mechanism includes: a second protective box 48 fixedly installed on one side of the collection box 29, the second protective box 48 covering the two second sprockets 40; a round rod 43 rotatably installed on the second protective box 48; a third shock absorption component 44 fixedly installed at the bottom end of the round rod 43; a rectangular rod 45 fixedly installed at the bottom end of the third shock absorption component 44; a rectangular seat 46 rotatably installed on the top of the first protective box 15 and connected to the rectangular rod 45; and two bevel gears 47 fixedly sleeved on the rotating shafts of the rectangular seat 46, the first sprocket 12, the connecting gear 42, and the top end of the round rod 43 respectively, the two bevel gears 47 being meshed with each other.

[0051] In this embodiment, during the tea drying process, when the servo motor 14 drives the first sprocket 12 to rotate, through the design of the linkage mechanism, the rotational force of the first sprocket 12 is transmitted to the bevel gear 47 meshed with it, and this bevel gear 47 drives the rectangular seat 46 connected to it to rotate. Since the rectangular seat 46 is connected to the rectangular rod 45, the rectangular rod 45 will also rotate accordingly. The rotation of the rectangular rod 45 further drives the round rod 43 to rotate, and the bevel gear 47 at the top end of the round rod 43 meshes with the bevel gear 47 on the rotating shaft of the connecting gear 42, thereby transmitting the rotational force to the connecting gear 42. The rotation of the connecting gear 42 drives the second sprocket 40 meshed with it to rotate, and then through the transmission of the second chain 41, the two cleaning brushes 39 rotate synchronously and rotate in opposite directions to clean the dust on the filter screen 36. Through the meshing transmission of the bevel gears 47, the power transmission between the first sprocket 12 and the connecting gear 42 is realized, improving the transmission efficiency. The addition of the third shock absorption component 44 reduces the impact of vibration on the linkage mechanism and enhances the stability of the device. Through the design of the second protective box 48, components such as the second sprocket 40 are protected, extending the service life of the components. Through the design of the linkage mechanism, the cleaning brush 39 can automatically rotate with the rotation of the first sprocket 12, improving the cleaning efficiency.

[0052] In summary, compared with the related technology, the present device can effectively improve the drying efficiency, achieve high-efficiency and uniform drying of tea, and at the same time save labor, improve work efficiency and drying quality.
