Abstract
Description
Technical Field
[0001] This invention relates to a leaf spreading device, specifically a leaf withering and spreading device for tea processing. Background Technology
[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include cha, jia, ming, and chuan. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all beneficial to health. Tea beverages are one of the world's three major beverages. The processing of tea involves a series of techniques, including picking, fixing (deactivating enzymes), drying, and sieving. The withering process is crucial for producing high-quality tea products.
[0003] Traditional tea withering typically involves spreading tea leaves evenly on a designated filter plate, then using external equipment to blow hot gas onto the leaves to meet processing requirements. After processing, the tea leaves are removed, tea debris is cleaned from the filter plate, and the leaves are then turned over and spread evenly. However, this process requires repeated manual operation, significantly impacting processing efficiency and making it unsuitable for large-scale processing. Therefore, this invention proposes a tea withering and spreading device to address these problems. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a withering and spreading device for tea processing.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0006] A withering and spreading device for tea processing includes a vertical frame. A movable mechanism is provided at the bottom of the vertical frame, and several storage boxes are fixedly connected to the outer side of the vertical frame. An outer frame is movably connected to the inner cavity of each storage box. A filter plate is fixedly connected to the inner cavity of the outer frame, and a positioning mechanism is provided at the top of the outer frame. Two racks are fixedly connected to the top of the outer frame, and gears mesh at the top of each rack. A rotating rod is fixedly connected between the two gears. Several cylinders are sleeved on the outer side of the rotating rod near both ends. Several movable rods are fixedly connected to the outer side of each cylinder, and an annular block is sleeved on the outer side of the rotating rod near the center. A connecting block is fixedly connected to the outer side of the annular block. The side of the connecting block away from the annular block extends to the bottom of the outer frame and is fixedly connected to an electric push rod.
[0007] As a preferred embodiment of the present invention, the moving mechanism includes a base plate, which is fixedly connected to the bottom of the vertical frame, and vertical blocks are fixedly connected to the bottom of the base plate near the left and right sides. A round shaft is rotatably connected through each of the two vertical blocks, and pulleys are fixedly connected to both the front and rear ends of the round shaft.
[0008] As a preferred embodiment of the present invention, the positioning mechanism includes a circular block, which is fixedly connected to the top of the outer frame, and a circular groove is provided on the top of the circular block. A spring is fixedly connected to the bottom of the inner wall of the circular groove, and a circular rod is fixedly connected to the top of the spring. Two circular holes are provided on the top of the storage box, and the top of the circular rod extends to the outside of the circular groove and is inserted into the inner cavity of the corresponding circular hole.
[0009] As a preferred embodiment of the present invention, two sliders are fixedly connected to the outer side of the outer frame, and grooves are provided on both sides of the inner wall of the storage box, with the sliders movably connected to the inner cavity of the corresponding grooves.
[0010] As a preferred embodiment of the present invention, two handles are fixedly connected to the side of the outer frame away from the vertical frame.
[0011] As a preferred embodiment of the present invention, the electric push rod is fixedly connected to a mounting block on the side away from the connecting block, and the mounting block is fixedly connected to the bottom of the outer frame.
[0012] As a preferred embodiment of the present invention, an L-shaped plate is fixedly connected to the bottom of the storage box, and baffles are fixedly connected to both sides of the L-shaped plate.
[0013] This invention provides a withering and spreading device for tea processing, comprising the following features:
[0014] Beneficial effects:
[0015] 1. The system is equipped with an electric push rod, connecting block, ring block, rotating rod, gear, and rack. By pulling the outer frame with the handle, the outer frame moves the filter plate, allowing the filter plate and its components to be pulled out from the storage box. The tea leaves to be processed are then spread evenly on the surface of the filter plate. The electric push rod is driven to extend and retract repeatedly, causing the connecting block to move repeatedly. The connecting block moves the ring block, which in turn moves the rotating rod. The rotating rod moves the movable rod on the outer cylinder, which in turn moves the gear. Because the gear meshes with the rack at the bottom, the gear rotates during movement, causing the rotating rod to rotate. The rotating rod then rotates the movable rod on the outer cylinder. Through the movement and rotation of the movable rod, the spread tea leaves are turned over, ensuring that all the tea leaves on a filter plate are fully exposed to light and in contact with it, thus maintaining a consistent withering state.
[0016] 2. By setting up multiple storage boxes, the filter plates inside the multiple storage boxes are separated so that when the filter plates are pulled out, the multiple filter plates are on the same horizontal plane. This ensures that the tea leaves on the multiple filter plates can fully contact the light and air, and ensures that the withering state of all the tea leaves on each filter plate is consistent.
[0017] 3. By setting up an L-shaped plate and a baffle, during the tea-turning process, tea leaves breakage falls through the filter plate onto the surface of the L-shaped plate and is blocked by the baffle, preventing it from falling. Afterwards, the staff only needs to clean the tea leaves breakage on the L-shaped plate, making the operation convenient.
[0018] 4. The device is equipped with a circular block, a circular groove, a spring, a circular rod, and a circular hole. When the outer frame needs to be moved, the circular rod needs to be pressed down to pull it out of the circular hole. At the same time, the circular rod compresses the spring inside the circular groove. At this time, the outer frame and the inside of the storage box are in a movable state. The operator can hold the handle and pull the outer frame outward so that the filter plate and other components on the outer frame can be moved smoothly to the outside. After being moved to the appropriate position, the circular rod will be reset under the elastic force of the spring and re-inserted into another circular hole to realize the positioning operation of the outer frame and other components, ensuring the stability of subsequent work.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0029] Example: Figure 1-7 As shown, a withering and spreading device for tea processing includes a vertical frame 1. The bottom of the vertical frame 1 is provided with a moving mechanism, and several storage boxes 6 are fixedly connected to the outside of the vertical frame 1. An outer frame 7 is movably connected to the inner cavity of the storage box 6. A filter plate 8 is fixedly connected to the inner cavity of the outer frame 7, and a positioning mechanism is provided at the top of the outer frame 7. Two racks 9 are fixedly connected to the top of the outer frame 7. Gears 10 are meshed at the top of the two racks 9. A rotating rod 11 is fixedly connected between the two gears 10. Several cylinders 12 are sleeved on the outer side of the rotating rod 11 near both ends. Several movable rods 13 are fixedly connected to the outer side of the cylinders 12. An annular block 14 is sleeved on the outer side of the rotating rod 11 near the center. A connecting block 15 is fixedly connected to the outer side of the annular block 14. The side of the connecting block 15 away from the annular block 14 extends to the bottom of the outer frame 7 and is fixedly connected to an electric push rod 16.
[0030] The moving mechanism includes a base plate 2, which is fixedly connected to the bottom of the vertical frame 1. Vertical blocks 3 are fixedly connected to the bottom of the base plate 2 near the left and right sides. A round shaft 4 is rotatably connected through the two vertical blocks 3. Pulleys 5 are fixedly connected to the front and rear ends of the round shaft 4.
[0031] In this embodiment, this setting allows the entire device to be moved freely under the action of the pulley 5, making it convenient to move the entire device indoors when the weather changes suddenly, thus avoiding the loss of tea leaves.
[0032] The positioning mechanism includes a round block 22, which is fixedly connected to the top of the outer frame 7. A round groove 23 is provided on the top of the round block 22. A spring 24 is fixedly connected to the bottom of the inner wall of the round groove 23. A round rod 25 is fixedly connected to the top of the spring 24. Two round holes 26 are provided on the top of the storage box 6. The top of the round rod 25 extends to the outside of the round groove 23 and is inserted into the inner cavity of the corresponding round hole 26.
[0033] In this embodiment, this setting enables the fixing operation between the outer frame 7 and the inside of the storage box 6, making the outer frame 7 sufficiently stable when stored inside the storage box 6, and also sufficiently stable when the outer frame 7 is moved to the outside of the storage box 6 for tea withering processing.
[0034] Among them, two sliders 20 are fixedly connected to the outer side of the outer frame 7, and grooves 19 are opened on both sides of the inner wall of the storage box 6. The sliders 20 are movably connected to the inner cavity of the corresponding grooves 19.
[0035] In this embodiment, this setting causes the slider 20 to slide inside the slide groove 19 when the outer frame 7 moves, thereby limiting the movement of the outer frame 7 and further improving the stability of the outer frame 7 during movement.
[0036] Two handles 27 are fixedly connected to the side of the outer frame 7 away from the vertical frame 1;
[0037] In this embodiment, this setting allows staff to easily move the outer frame 7 by holding the handle 27.
[0038] Among them, the electric push rod 16 is fixedly connected to the mounting block 17 on the side away from the connecting block 15, and the mounting block 17 is fixedly connected to the bottom of the outer frame 7;
[0039] In this embodiment, this setting enables the prescribed operation between the electric push rod 16 and the outer frame 7, allowing the electric push rod 16 to move synchronously with the movement of the outer frame 7, thereby ensuring that subsequent material turning operations can be carried out stably.
[0040] Among them, the bottom of the storage box 6 is fixedly connected to an L-shaped plate 18, and baffles 21 are fixedly connected to both sides of the L-shaped plate 18.
[0041] In this embodiment, this setting can catch the tea leaves that fall from the filter plate 8, making it easier to clean later.
[0042] Working Principle: In use, first move the entire device outdoors using the bottom pulley 5. Then, position the pulley 5 and press down on the round rod 25, causing it to pull out of the round hole 26. Simultaneously, the round rod 25 compresses the spring 24 inside the round groove 23. At this point, the outer frame 7 and the inside of the storage box 6 are in a movable state. The operator can hold the handle 27 and pull the outer frame 7 outwards, allowing the filter plate 8 and other components on the outer frame 7 to move smoothly to the outside. After moving to the appropriate position, the round rod 25 will reset under the elastic force of the spring 24 and re-insert into another round hole 26, achieving the positioning operation of the outer frame 7 and other components, ensuring the stability of subsequent work. Then, the operator can spread the tea leaves to be processed evenly on the surface of the filter plate 8 and drive the electric push rod 16 to repeatedly extend and retract, causing the electric push rod 16 to drive the connecting block 15 to move repeatedly. The connecting block 15 then drives the annular block 14 to move. The annular block 14 drives the rotating rod 11 to move, which in turn drives the movable rod 13 on the outer cylinder 12 to move, and simultaneously drives the gear 10 to move. Since the bottom of the gear 10 is meshed with a rack 9, the gear 10 will rotate when it moves, thereby driving the rotating rod 11 to rotate. The rotating rod 11 drives the movable rod 13 on the outer cylinder 12 to rotate. Through the movement and rotation of the movable rod 13, the evenly spread tea leaves can be turned over, so that all the tea leaves on a filter plate 8 can be fully exposed to light and in contact, ensuring that all the tea leaves on a filter plate 8 have a consistent withering state. During the process of turning over the tea leaves, the filter plate 8 and other components will vibrate slightly, causing the tea leaves on the surface of the filter plate 8 to fall onto the top of the L-shaped plate 18. The baffle 21 on the L-shaped plate 18 will block the tea leaves and prevent them from scattering everywhere. The tea leaves on the L-shaped plate 18 can then be directly processed, making the operation convenient.
