Description

Technical Field

[0001] This utility model relates to the technical field of tea production equipment, and in particular to a tea spreading device. Background Technology

[0002] Withering is the first step in tea processing. It involves spreading fresh tea leaves under specific environmental conditions to allow them to lose moisture, resulting in physical changes such as cell shrinkage, reduced leaf area, and softening of the leaves, as well as a series of chemical changes such as hydrolysis and oxidation of internal substances. Currently, withering is generally done using multi-layered withering racks with bamboo trays for placing the tea leaves. However, this method is inconvenient for collecting the tea leaves, requiring time-consuming and labor-intensive layer-by-layer collection, resulting in high labor costs and low collection efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this application provides a tea-spreading device.

[0004] This application provides a tea-withering device, which adopts the following technical solution:

[0005] A tea-spreading device includes a support frame, on which a plurality of placement racks are evenly arranged vertically, and on each placement rack a plurality of spreading frames are evenly arranged along its length. A horizontal groove is formed on the side wall of the support frame, and a slider is slidably disposed within the groove. The slider is connected to the end of each placement frame. A driving component is provided on the support frame to drive the placement racks to reciprocate along the length of the groove. A flipping component is provided on each placement rack to drive the spreading frames to flip. A recycling component is provided on the support frame to facilitate the collection of tea leaves.

[0006] By adopting the above technical solution, the driving component drives the placement frame to move back and forth along the length of the chute, thereby causing the tea leaves in the spreading frame to shake back and forth, achieving a sieving effect similar to that of a sieve. This facilitates the leveling of the tea leaves and promotes airflow within them, improving the spreading effect. When the tea spreading is complete, the flipping component drives multiple spreading frames to flip synchronously, causing the tea leaves to fall outside the spreading frames under gravity. At this point, the recycling component collects the tea leaves after the withering process, enabling convenient and rapid tea leaf recycling, reducing the labor intensity of workers, and improving production efficiency.

[0007] Optionally, the drive assembly includes a first drive motor, which is fixedly mounted on a support frame. A crank is mounted on the output shaft of the first drive motor. A rocker arm is hinged to the end of the crank arm away from the first drive motor. The end of the rocker arm away from the crank arm is hinged to a slider. The multiple sliders are connected to each other by a connecting rod.

[0008] By adopting the above technical solution, the driving component will push the slider to move back and forth along the length of the chute, thereby causing the placement frame to move back and forth along the length of the chute, thus spreading the tea leaves evenly in the spreading frame and improving the tea spreading effect.

[0009] Optionally, the flipping assembly includes a power motor and multiple rotating shafts. Each of the multiple rotating shafts corresponds to and is connected to a multiple spreading frames, and each of the multiple rotating shafts is rotatably connected to a placement frame. A worm gear is coaxially mounted on the end of each rotating shaft away from the spreading frame. A worm is rotatably mounted on the placement frame, and the worm meshes with the worm gear. The power motor is fixedly mounted on a support frame, and the output shaft of the power motor is coaxially connected to the worm.

[0010] By adopting the above technical solution, the flipping component can drive multiple tea-spreading frames to flip, thereby enabling rapid tea-discharging.

[0011] Optionally, the recycling assembly includes multiple guide plates, each corresponding to a multiple placement rack. The guide plates are inclinedly arranged at the bottom of the placement rack. An extended recycling plate is provided on the guide plate near the ground on the support frame. A recycling box for recycling tea leaves is provided at the bottom of the support frame, and the top of the recycling box is open.

[0012] By adopting the above technical solution, the tea leaves will fall onto the extended recovery plate under the action of gravity, and then the extended recovery plate will guide the tea leaves into the recovery box, thereby automatically collecting the tea leaves.

[0013] Optionally, the support frame is further provided with a stirring assembly for agitating the tea leaves in the spreading frame. The stirring assembly includes a mounting rod, a lifting rod that slides vertically on the mounting rod, a stirring seat at the bottom of the lifting rod, and second springs on both sides of the stirring seat. The other end of the second spring is connected to the mounting rod. Multiple stirring teeth for agitating the tea leaves are evenly arranged at the bottom of the stirring seat. The support frame has a guide groove, and the end of the mounting rod is slidably disposed in the guide groove. A guide block is inclinedly disposed at the end of the spreading frame, and the top of the guide block is flush with the top of the placement frame. A lead screw is rotatably disposed in the guide groove and is threadedly connected to the mounting rod. A second drive motor is provided on the support frame, and the output shaft of the second drive motor is coaxially connected to the lead screw.

[0014] By adopting the above technical solution, the agitator can move the tea leaves, thereby improving the withering effect of the tea leaves.

[0015] Optionally, the extended recycling plate is provided with two guide strips, which form a V-shape to guide the tea leaves into the recycling box.

[0016] By adopting the above technical solution, two guide strips are used to further guide the tea leaves on the extended recycling plate, so that the tea leaves can easily fall into the recycling box.

[0017] Optionally, the support frame is provided with a placement plate for supporting the toggle seat.

[0018] By adopting the above technical solution, the actuating seat is moved to a placement plate away from the spreading frame, thereby avoiding the actuating seat affecting the flipping component and the rotation of the spreading frame.

[0019] Optionally, a first spring is installed at both ends of the chute, and multiple through holes are evenly opened on the bottom surface of the spreading frame.

[0020] By adopting the above technical solution, the first spring can buffer the placement rack and to a certain extent prevent the placement rack from hitting the support frame during movement, and the multiple through holes facilitate the circulation of air in the tea leaves in the spreading frame.

[0021] This utility model has the following advantages:

[0022] 1. By setting up flipping and recycling components, tea leaves can be collected quickly and uniformly, resulting in high collection efficiency and low production costs.

[0023] 2. By configuring the driver components, the withering effect of tea leaves can be improved;

[0030] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0031] like Figures 1 to 4 As shown, a tea-spreading device includes a support frame 1, on which multiple placement racks 11 are evenly installed vertically, and multiple spreading frames 12 are evenly installed along their length on each placement rack 11. A horizontal groove 13 is formed on the side wall of the support frame 1, and a slider 14 is slidably installed within the groove 13, connected to the end of each placement frame. A drive assembly 2 is installed on the support frame 1 to drive the placement racks 11 to reciprocate along the length of the groove 13. A flipping assembly 3 is installed on the placement racks 11 to drive the spreading frames 12 to flip. A recycling assembly 4 is installed on the support frame 1 to facilitate the recycling of tea leaves. In use, fresh tea leaves are spread on the spreading frames 11. 2. Then, the drive component 2 drives the placement frame 11 to move back and forth along the length of the chute 13. During the reciprocating movement of the placement frame 11, the tea leaves in the spreading frame 12 will sway back and forth under the action of inertia, which plays a similar role to sieving, thereby making it easier to level the tea leaves and facilitate the flow of air in the tea leaves, thus improving the spreading effect. When the tea leaves are spread out, the flipping component 3 drives multiple spreading frames 12 to flip synchronously. The tea leaves will fall outside the spreading frame 12 under the action of gravity. At this time, the recycling component 4 is used to collect the tea leaves after the withering is completed, which can facilitate the quick recycling of tea leaves, reduce the labor intensity of workers, and improve production efficiency.

[0032] like Figures 1 to 4As shown, the drive assembly 2 includes a first drive motor, which is fixedly mounted on the support frame 1. A crank 22 is mounted on the output shaft of the first drive motor. A rocker arm 23 is hinged to the end of the crank 22 away from the first drive motor. The end of the rocker arm 23 away from the crank 22 is hinged to the slider 14. Multiple sliders 14 are connected to each other through connecting rods 24. In use, when the first drive motor is started, the first drive motor will drive the crank 22 to rotate. The crank 22 will drive the rocker arm 23 to move. The rocker arm 23 will push the slider 14 to move back and forth along the length of the slide groove 13.

[0033] like Figures 1 to 4 As shown, the flipping assembly 3 includes a power motor 31 and multiple rotating shafts 32. Each rotating shaft 32 corresponds to and is connected to one of the multiple spreading frames 12. All rotating shafts 32 are rotatably connected to the placement frame 11. A worm gear 33 is coaxially mounted on the end of each rotating shaft 32 away from the spreading frame 12. A worm 34 is rotatably mounted on the placement frame 11, meshing with the worm gear 33. The power motor 31 is fixedly mounted on the support frame 1, and its output shaft is coaxially connected to the worm 34. Since each spreading frame 12 is rotatably mounted on the placement frame 11 via a rotating shaft 32, the rotating shaft 32 is equipped with... There is a worm gear 33, so multiple worms 34 are rotatably mounted on the placement frame 11. The multiple worms 34 are all coaxially connected, and each of the multiple worms 34 corresponds to a multiple worm gears 33, and the worms 34 mesh with the worm gears 33. When in use, the power motor 31 is started. During the rotation of the power motor 31, the worms 34 will rotate. During the rotation of the worms 34, the worm gears 33 will rotate. During the rotation of the worm gears 33, the rotating shaft 32 will rotate. During the rotation of the rotating shaft 32, the tea spreading frame 12 will be flipped, so that the tea leaves inside the tea spreading frame 12 fall out, thus facilitating the discharge of the tea.

[0034] like Figures 1 to 4 As shown, the recycling component 4 includes multiple guide plates 41, each corresponding to a different placement rack 11. The guide plates 41 are installed at an angle at the bottom of the placement rack 11. An extended recycling plate 42 is installed on the guide plate 41 near the ground on the support frame 1. A recycling box 43 for recycling tea leaves is installed at the bottom of the support frame 1, with an opening at the top. When the flipping component 3 drives the spreading frame 12 to flip, the tea leaves inside the spreading frame 12 will fall onto the guide plate 41 under the action of gravity. The guide plate 41 is inclined, so the tea leaves falling onto the guide plate 41 will slide along the guide plate 41. The extended recycling plate 42 is used to lengthen the guide plate 41, so the tea leaves will fall onto the extended recycling plate 42 under the action of gravity. Then, the extended recycling plate 42 guides the tea leaves into the recycling box 43, thereby automatically collecting the tea leaves.

[0035] like Figures 1 to 4As shown, the support frame 1 is also equipped with a stirring assembly 5 for moving the tea leaves in the spreading frame 12. The stirring assembly 5 includes a mounting rod 51, a lifting rod 52 that slides vertically on the mounting rod 51, a stirring seat 53 that is installed at the bottom of the lifting rod 52, and second springs 54 that are installed on the stirring seat 53 on both sides of the lifting rod 52. The other end of the second springs 54 is connected to the mounting rod 51. A plurality of stirring teeth 55 for moving the tea leaves are evenly installed at the bottom of the stirring seat 53. The support frame 1 is provided with a guide groove 56. The end of the spreading frame 12 is slidably installed in the guide groove 56. The end of the spreading frame 12 is inclinedly installed with a guide block 57. The top of the guide block 57 is flush with the top of the placement frame 11. A lead screw 58 is rotatably installed in the guide groove 56. The lead screw 58 is threadedly connected to the mounting rod 51. A second drive motor 59 is installed on the support frame 1. The output shaft of the second drive motor 59 is coaxially connected to the lead screw 58. In use, the second drive motor 59 is started. During the rotation of the second drive motor 59, the lead screw 58 will be driven to rotate. During the rotation of the lead screw 58, the mounting rod 51 will be driven to move along the guide groove 56. As the groove 56 moves along its length, the mounting rod 51 moves, causing the actuating seat 53 to move. When the actuating seat 53 moves into the spreading frame 12, under the action of the second spring 54, the bottom of the actuating seat 53 will abut against the bottom surface of the spreading frame 12. When the actuating seat 53 is in the middle position of the stationary spreading frame 12, the second drive motor 59 stops rotating. Then, under the action of the drive assembly 2, the placement frame 11 drives the spreading frame 12 to reciprocate along the length of the slide groove 13. At this time, the actuating seat 53 is stationary, so the spreading frame 12 will abut against the actuating seat 53. The moving seat 53 undergoes relative movement. Multiple actuating teeth 55 are installed at the bottom of the actuating seat 53 to facilitate the actuation of the tea leaves. When the actuation ends, the second drive motor 59 rotates in the opposite direction, causing the actuating seat 53 to move along the length of the guide groove 56. When the bottom of the actuating seat 53 moves to the position of the guide block 57, the second spring 54 will be gradually compressed, and the actuating seat 53 will move toward the position close to the mounting rod 51, so that the actuating seat 53 can move to a position away from the spreading frame 12, thereby not affecting the flipping assembly 3 driving the spreading frame 12 to flip.

[0036] like Figures 1 to 4 As shown, two guide strips 44 are installed on the extended recycling plate 42. The two guide strips 44 form a V-shape to guide the tea leaves to the recycling box 43. The two guide strips 44 are used to further guide the tea leaves on the extended recycling plate 42 so that the tea leaves can fall into the recycling box 43 easily.

[0037] like Figures 1 to 4As shown, a placement plate 16 is installed on the support frame 1. The placement plate 16 is used to support the agitator 53. In use, after the agitator 53 has finished agitating the tea leaves, the second drive motor 59 will drive the mounting rod 51 to move along the guide groove 56, thereby moving the agitator 53 to the placement plate 16 away from the tea-spreading frame 12, thus preventing the agitator 53 from affecting the rotation of the flipping assembly 3 and the tea-spreading frame 12.

[0038] like Figures 1 to 4 As shown, a first spring 15 is installed at both ends of the slide 13, and multiple through holes 17 are evenly opened on the bottom surface of the spreading frame 12. By installing the first spring 15 on both sides of the slide 13, the first spring 15 can buffer the placing frame 11 as it moves back and forth along the length of the slide 13, thus avoiding the placing frame 11 from hitting the support frame 1 during movement to a certain extent. By evenly opening multiple through holes 17 on the bottom surface of the spreading frame 12, air can circulate in the tea leaves inside the spreading frame 12.

[0039] The implementation principle of this embodiment is as follows: In use, fresh tea leaves are laid on the spreading frame 12, and then the drive component 2 drives the placement frame 11 to move back and forth along the length of the slide 13. During the reciprocating movement of the placement frame 11, the tea leaves in the spreading frame 12 will sway back and forth under the action of inertia, which has a similar effect to sieving, thus making it easier to level the tea leaves and facilitate the flow of air in the tea leaves, thereby improving the spreading effect. When the tea leaves are spread out, the flipping component 3 drives multiple spreading frames 12 to flip synchronously. The tea leaves will fall outside the spreading frame 12 under the action of gravity. At this time, the recycling component 4 is used to collect the tea leaves after the withering is completed, which can conveniently and quickly recycle the tea leaves, reduce the labor intensity of the workers, and improve production efficiency.

Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
