Description

Technical Field

[0001] This application relates to the technical field of drying equipment, and in particular to a tea drying machine for jasmine tea production. Background Technology

[0002] Jasmine tea is a type of flower tea. Its production mainly involves infusing the green tea leaves with the fragrance of jasmine flowers multiple times.

[0003] Currently, the main steps in the production of jasmine tea tea leaves include fixation, rolling, and drying. Drying is used to evaporate the moisture in the tea leaves. Traditionally, drying is done by roasting over charcoal. However, to adapt to the ever-increasing tea production, drying machines have been applied to the field of tea drying.

[0004] During the drying process, tea leaves are piled on drying trays, which are then placed in a drying machine and started. The machine generates heat to dry the tea leaves on the trays. However, the tea leaves on the surface directly receive the heat and are dried more effectively, while the tea leaves below the surface need to be dried through heat transfer, resulting in a less effective drying. Therefore, to ensure that all the tea leaves are dried, the drying time needs to be extended. Summary of the Invention

[0005] To shorten the drying time, this application provides a tea drying machine for jasmine tea production.

[0006] This application provides a tea drying machine for jasmine tea production, which adopts the following technical solution:

[0007] A tea drying machine for jasmine tea production includes a machine body with a drying chamber inside. A hot air pipe communicating with the drying chamber is located at the bottom of the machine body, and an air outlet pipe communicating with the drying chamber is located at the top of the machine body. The machine body is equipped with multiple conveyor belts located within the drying chamber, spaced vertically. An inlet pipe is located at the top of the machine body, and an outlet pipe is located at the bottom. A feeding port for conveying tea leaves to the conveyor belt is formed between the conveyor belts and the vertical sidewall of the machine body. Adjacent feeding ports are staggered. The machine body is equipped with a drive assembly for driving the conveyor belts to convey tea leaves to the feeding port. The conveyor belts are connected end-to-end to form an installation cavity. The machine body is equipped with a support portion extending into the installation cavity. A connecting column is slidably mounted on the support portion. The support portion is equipped with an elastic drive member that drives the connecting column to impact the conveyor belt upwards. The machine body is equipped with a transmission assembly that drives the elastic drive member to elastically accumulate and release when the conveyor belt moves.

[0008] By adopting the above technical solution, when the machine is started, the drive component drives the conveyor belt to move. Then, hot air is introduced into the drying chamber through the air inlet pipe, and the tea leaves to be dried are then fed into the drying chamber through the feed pipe, causing the tea leaves to fall onto the uppermost conveyor belt. The conveyor belt then transports the tea leaves to the feed inlet, allowing them to fall from the feed inlet onto the lower conveyor belt. During the conveying process, the tea leaves are dried by the hot air. As the conveyor belt moves, the transmission component drives the elastic drive component to accumulate and release elastic force, causing the connecting column to impact the conveyor belt upwards, generating vibration and causing the tea leaves to tumble. This allows the tea leaves in the lower layer to be better dried by the hot air, improving the drying effect and greatly shortening the drying time.

[0009] Optionally, the drive assembly includes a drive motor and drive gears. The machine body is rotatably connected to multiple conveyor rollers. The conveyor belt is sleeved on the conveyor rollers. The drive gears are multiple and are respectively arranged on the same side of the upper and lower adjacent conveyor rollers. The upper and lower drive gears mesh with each other. The drive motor is arranged on the machine body, and the output shaft of the drive motor is connected to the conveyor rollers.

[0010] By adopting the above technical solution, when in use, the drive motor starts and drives the conveyor roller to rotate. At this time, the drive gear transmits power and drives the transmission roller below to rotate, so that the conveyor belt can be driven.

[0011] Optionally, the elastic driving component is a driving spring, which is sleeved on the outer periphery of the connecting column. A limiting block is provided on the outer periphery of the connecting column. One end of the driving spring abuts against the limiting block, and the other end abuts against the bearing portion.

[0012] By adopting the above technical solution, the drive spring is released elastically during use, pushing the connecting column to move upward and impact the conveyor belt. This causes the tea leaves on the conveyor belt to vibrate and jump, thereby causing the tea leaves in the lower layer to flip to the upper layer, so that they can be better dried by the hot air and the drying effect can be improved.

[0013] Optionally, the transmission assembly includes a transmission roller and a transmission belt. The transmission roller rotates within the machine body and is located in the mounting cavity. The transmission belt is sleeved on the transmission roller and the conveying roller away from the material inlet. A power plate is provided on the outer periphery of the conveying roller. When the power plate flips toward the bearing part, the power plate abuts against the top of the limiting block. When the power plate flips away from the connecting column, the power plate moves away from the limiting block. The machine body is provided with a control assembly that controls the limiting block to slide below the power plate when the power plate flips toward the connecting column.

[0014] By adopting the above technical solution, when the conveyor roller drives the transmission roller to rotate, the power plate drives the limiting block to slide downward, causing the drive spring to contract. When the power plate moves away from the limiting block, the drive spring is released elastically, causing the connecting column to move upward, so that the connecting column hits the upper conveyor belt, causing the tea leaves to vibrate and tumble.

[0015] Optionally, the control assembly includes a control rope and a control plate. The control rope passes through the drive spring, and a slider is slidably disposed on the side wall of the machine body. One end of the control rope is connected to the bottom of the limiting block, and the other end is connected to the slider. The control plate is disposed on the outer periphery of the transmission roller and close to the slider. When the power plate approaches the connecting column, the control plate drives the slider to slide, causing the control rope to pull the limiting block downward. When the power plate moves to directly above the limiting block, the control plate moves away from the slider.

[0016] By adopting the above technical solution, when the power plate flips towards the connecting column, the control plate drives the slider to slide, causing the control rope to pull the limiting block downwards until the power plate moves directly above the limiting block. At this time, the control plate moves away from the limiting block, and the power plate can then drive the limiting block downwards.

[0017] Optionally, the bearing portion is provided with a guide ring for guiding the control rope to slide.

[0018] By adopting the above technical solution, the guide ring guides the movement trajectory of the control rope, enabling the control rope to better pull the limiting block downward.

[0019] Optionally, the machine body is provided with a flat plate, which is located above the conveyor belt and forms a flattening cavity with the conveyor belt.

[0020] By adopting the above technical solution, the tea leaves are spread out on a flat plate, which allows the tea leaves to be dried more effectively.

[0021] Optionally, the spreading plate slides up and down on the machine body, the machine body is provided with a power spring that drives the spreading plate away from the conveyor belt, and a connecting rope slides through the machine body, one end of the connecting rope being connected to the bottom of the spreading plate and the other end being connected to the sliding ball.

[0022] By adopting the above technical solution, the tea leaves are spread out on the flat plate before the connecting column hits the conveyor belt upwards, and the flat plate moves away from the conveyor belt when the connecting column hits the conveyor belt upwards, reducing the possibility of the connecting column and the flat plate colliding with each other.

[0023] Optionally, a connecting plate is provided at the top of the connecting column.

[0024] By adopting the above technical solution, the area of ​​the connecting column impacting the conveyor belt is increased, thereby improving the tea leaf tumbling effect.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. During the process of conveying tea leaves, the connecting column impacts the conveyor belt upwards, causing the tea leaves to tumble and move the lower layer of tea leaves to the upper layer, where they are better dried by the hot air, thus shortening the drying time of the tea leaves.

[0027] 2. Spread the tea leaves evenly on a flat surface so that they can be dried more effectively. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a tea drying machine for jasmine tea production. See also... Figure 1 and Figure 2The tea drying machine for jasmine tea production includes a machine body 1. A drying chamber 11 is formed inside the machine body 1. A hot air pipe 12 is fixedly connected to the bottom of the machine body 1, and the hot air pipe 12 is connected to the drying chamber 11. Hot air generated by an external heater is introduced into the drying chamber 11 through the hot air pipe 12. An exhaust pipe 13 is fixedly connected to the top of the machine body 1, and the hot air in the drying chamber 11 is discharged through the exhaust pipe 13.

[0036] See Figure 2 The machine body 1 has multiple sets of conveyor rollers 142 evenly spaced vertically. Each set of conveyor rollers 142 has two rollers arranged symmetrically, and the conveyor rollers 142 are rotatably connected to the vertical sidewall of the machine body 1. The machine body 1 is provided with conveyor belts 14 connected end to end, with each conveyor belt 14 mounted on two conveyor belts 14 in the same set. A material inlet 17 is formed between the conveyor belt 14 and one vertical sidewall of the machine body 1, and the adjacent material inlets 17 are staggered.

[0037] See Figure 2 The top of the machine body 1 is fixedly connected to a feed pipe 15, which is connected to the drying chamber 11 and faces the conveyor belt 14. The tea leaves to be dried are fed into the drying chamber 11 through the feed pipe 15 and fall onto the conveyor belt 14. When the conveyor belt 14 moves, it drives the tea leaves toward the feed inlet 17. Then, the tea leaves on the upper conveyor belt 14 fall onto the lower adjacent conveyor belt 14.

[0038] See Figure 2 and Figure 3 The machine body 1 is equipped with a drive assembly 2 for simultaneously driving all conveyor belts 14 to transport tea leaves to the feed inlet 17, with adjacent conveyor belts 14 moving in opposite directions. The drive assembly 2 includes a drive motor 21 and drive gears 22. A mounting groove 7 is formed in the vertical sidewall of the machine body 1 opposite to the end of the conveyor roller 142, and the end of the conveyor roller 142 extends into the mounting groove 7. The drive gears 22 are fixed to the outer periphery of the conveyor roller 142 and located within the mounting groove 7, with adjacent drive gears 22 meshing with each other. The drive motor 21 is fixed to the outer wall of the machine body 1, and its output shaft is fixedly connected to one of the uppermost conveyor rollers 142. When the drive motor 21 starts, it drives the conveyor roller 142 to rotate, which in turn drives the conveyor belts 14 to reciprocate, thus transporting the tea leaves.

[0039] See Figure 2 and Figure 4 The conveyor belts 14 connected end to end form an installation cavity 141. A support portion 18 is provided between the opposite side walls of the machine body 1. The support portion 18 is a long strip-shaped structure with both ends fixed to the side walls of the machine body 1. The support portion 18 is located inside the installation cavity 141, and the distance between the support portion 18 and the two conveyor rollers 142 in the same group is equal. A connecting column 181 slides through the support portion 18, and the connecting column 181 is located in the middle of the support portion 18.

[0040] See Figure 4 Two limiting blocks 183 are symmetrically fixed to the outer periphery of the connecting column 181. The bearing part 18 is provided with an elastic driving element, which is a driving spring 182. The driving spring 182 is sleeved on the outer periphery of the connecting column 181, with the top of the driving spring 182 abutting against the bottom of the limiting block 183 and the bottom of the driving spring 182 abutting against the top of the bearing part 18. In use, the driving spring 182 is released elastically, pushing the connecting column 181 to move upward and impact the conveyor belt 14, causing the tea leaves on the conveyor belt 14 to jump upward and flip, thus flipping the tea leaves in the lower layer to the upper layer. A connecting plate 184 is fixedly connected to the top of the connecting column 181. The opposite ends of the connecting plate 184 extend towards the two conveyor rollers 142 in the same group to increase the contact area with the conveyor belt 14 and expand the range of tea leaf flipping.

[0041] See Figure 4 and Figure 5 The machine body 1 is equipped with a transmission component 3. When the conveyor roller 142 rotates, the transmission component 3 transmits power, which drives the drive spring 182 to accumulate elasticity and then release it.

[0042] See Figure 4 and Figure 5 The transmission assembly 3 includes a transmission roller 31 and a transmission belt 32. The transmission roller 31 corresponds one-to-one with the connecting column 181 and is located in the mounting cavity 141. The two ends of the transmission roller 31 are rotatably connected to the side wall of the machine body 1 and are parallel to the conveying roller 142. The transmission roller 31 is located on the side of the connecting column 181 away from the feed port 17. A transmission groove 6 is opened on the vertical groove wall of the machine body 1 away from the mounting groove 7. The transmission roller 31 and the conveying roller 142 extend into the transmission groove 6. The transmission belt 32 corresponds one-to-one with the transmission roller 31 and is sleeved on the transmission roller 31 and at the same horizontal height away from the feed port 17 (the feed port 17 is located in the mounting groove 7). Figure 2 On the conveyor roller 142 (marked in the middle), the diameter of the drive roller 31 is much smaller than the diameter of the conveyor roller 142. When the conveyor roller 142 rotates, the drive roller 31 rotates with the conveyor roller 142.

[0043] See Figure 4A power plate 311 is fixedly connected to the outer periphery of the transmission roller 31, and the power plate 311 corresponds to the limiting block 183. When the transmission roller 31 rotates, the power plate 311 rotates towards the bearing part 18. The power plate 311 first flips and approaches the connecting column 181, and then flips downward to abut against the limiting block 183. Then, as the transmission roller 31 continues to rotate, the power plate 311 pushes the limiting block 183 downward, causing the connecting column 181 to slide downward. At this time, the drive spring 182 enters the elastic continuous state. When the power plate 311 flips away from the connecting column 181, the power plate 311 moves away from the limiting block 183. At this time, the drive spring 182 is released elastically, pushing the connecting column 181 to move upward, causing the connecting plate 184 to hit the conveyor belt 14, generating vibration to tumble the tea leaves.

[0044] See Figure 2 and Figure 4 The body 1 is equipped with a control component 4. When the power plate 311 flips toward the connecting column 181, the control component 4 first controls the limiting block 183 to move downward, so that the limiting block 183 is located below the power plate 311, so that the power plate 311 can push the limiting block 183 downward.

[0045] See Figure 4 The control component 4 includes a control rope 41 and a control plate 42. The control plate 42 is fixed to the outer periphery of the transmission roller 31 and close to the side wall of the machine body 1. The control plate 42 and the power plate 311 are set at an acute angle.

[0046] See Figure 2 and Figure 4 The machine body 1 has a groove 44 on its side wall near the control panel 42, with its extension direction perpendicular to the central axis of the transmission roller 31. The machine body 1 is provided with a slider 43, which slides within the groove 44. Limiting strips are fixedly connected to the upper and lower walls of the groove 44, and the slider 43 protrudes from between the two limiting strips to the outside of the groove 44. At this time, the limiting strips prevent the slider 43 from disengaging from the groove 44.

[0047] See Figure 2 and Figure 4The control rope 41 slides through the drive spring 182, with one end fixed to the bottom of the limiting block 183 and the other end fixed to the slider 43. Multiple guide rings 45 are fixedly connected to the top of the bearing part 18. The control rope 41 slides through the guide rings 45 to guide the control rope 41, allowing it to slide along the bearing part 18. When the power plate 311 flips towards the connecting post 181, the power plate 311 drives the slider 43 to slide away from the connecting post 181. At this time, the control rope 41 pulls the limiting block 183 downwards, allowing the limiting block 183 to move below the power plate 311. Then, as the transmission roller 31 continues to rotate, the control plate 42 slides relative to the slider 43 until the control plate 42 moves away from the slider 43. After the control plate 42 moves away from the slider 43, the drive spring 182 drives the limiting block 183 to slide upwards until it abuts the bottom of the power plate 311. At this time, the control rope 41 pulls the slider 43 back to its original position and returns it to its reset state.

[0048] See Figure 2 and Figure 4 The machine body 1 is equipped with a spreading plate 5, which corresponds one-to-one with the conveyor belt 14 and is located directly above the conveyor belt 14. Vertical sliding grooves 19 are formed on the opposite side walls of the machine body 1, and the two ends of the spreading plate 5 slide up and down in the sliding grooves 19. A power spring 52 is provided on the machine body 1, which corresponds one-to-one with the sliding groove 19 and is installed within the sliding groove 19. One end of the power spring 52 abuts against the bottom of the spreading plate 5, and the other end abuts against the bottom wall of the sliding groove 19. During use, the power spring 52 releases its elasticity, pushing the spreading plate 5 away from the conveyor belt 14. A connecting rope 53 slides through the machine body 1, with one end of the connecting rope 53 fixed to the bottom of the spreading plate 5 and the other end fixed to a sliding ball 43. When the slider 43 slides, the connecting rope 53 pulls the spreading plate 5 downwards to a position close to the conveyor belt 14. At this time, a spreading cavity 51 is formed between the spreading plate 5 and the conveyor belt 14, and the tea leaves pass through the spreading cavity 51. The spreading plate 5 then spreads the piled-up tea leaves flat. When the connecting column 181 moves upwards, the spreading plate 5 moves upwards away from the conveyor belt 14, reducing the possibility of the connecting plate 184 colliding with the spreading plate 5 when it hits the conveyor belt 14.

[0049] The implementation principle of a tea drying machine for jasmine tea production according to an embodiment of this application is as follows:

[0050] When in use, the machine body 1 is started, causing the drive motor 21 to drive the conveyor belt 14 to transport the tea leaves and introduce hot air into the drying chamber 11. Then, the tea leaves to be dried are poured in through the feed pipe 15, and the conveyor belt 14 transports the tea leaves at a slow speed to ensure better drying. While the conveyor belt 14 is transporting the tea leaves, the connecting column 181 moves up and down, impacting the conveyor belt 14 and causing the tea leaves on it to vibrate and tumble, facilitating better drying of the lower layers of tea leaves by the hot air. Simultaneously, the tea leaves are spread evenly by the spreading plate 5. When the tea leaves are dried, they are output from the discharge pipe 16.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
