Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a tea-spreading device for tea processing. Background Technology

[0002] Tea leaf withering is a process where fresh tea leaves are spread out after picking and before being processed. This allows the leaves to dry out excess moisture and wilt to the appropriate degree before being processed. The withering process is beneficial for improving the physicochemical changes in tea quality, thus enhancing the overall quality of the tea. Therefore, the withering process is quite important in tea production.

[0003] The existing method of spreading tea leaves withering is generally done manually. Specifically, after the tea leaves are picked, they are manually spread out on a flat surface and then ventilated and dried to achieve the withering process. However, this method of spreading tea leaves withering is inefficient and requires a lot of manual labor. Therefore, a tea processing withering device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tea-spreading device for tea processing, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tea-spreading device for tea processing, including a base plate, two fixed plates fixedly connected to the top of the base plate, a frame slidably connected between the two fixed plates, a mesh plate fixedly connected to the lower inner wall of the frame, a spreading mechanism on the frame, and a sieving mechanism on the fixed plates.

[0006] The spreading mechanism includes: a mounting groove, which is opened on the left inner wall of the frame and close to the top of the frame. The inner wall of the mounting groove is rotatably connected to a bidirectional threaded rod through a bearing. The reverse threads of the bidirectional threaded rod are respectively threaded to sliders, and the outer wall of each slider is slidably connected to the inner wall of the mounting groove. The right side of each slider is fixedly connected to a spreading plate.

[0007] Preferably, a first motor is connected to the front of the frame, and the front end of the bidirectional threaded rod passes through the frame and is fixedly connected to the output end of the first motor through a coupling. The bidirectional threaded rod can be driven to rotate by starting the first motor.

[0008] Preferably, the frame has an opening on the back and a slot at the top rear of the frame, into which a baffle is inserted. By pulling the baffle upward, the tea leaves can be separated from the frame for easy recycling.

[0009] Preferably, the screening mechanism includes: a rotating shaft, which is rotatably connected to the right side of the fixed plate on the left side via a bearing; a connecting strip is fixedly connected to the right end of the rotating shaft; a limiting sleeve is fixedly connected to the right side of the fixed plate; a slide bar is slidably connected to the inner wall of the limiting sleeve; a hinge arm is hinged to the front of the slide bar, and the other end of the hinge arm is hinged to the top of the connecting strip; a connecting plate is fixedly connected to the back of the slide bar, and the top of the connecting plate is fixedly connected to the bottom of the frame.

[0010] Preferably, a second motor is connected to the left side of the fixed plate, and the left end of the rotating shaft passes through the fixed plate and is fixedly connected to the output end of the second motor through a coupling. The rotating shaft can be driven to rotate by starting the second motor.

[0011] Preferably, the bottom of the base plate is connected to four casters, which are respectively connected to the four corners of the bottom of the base plate. The casters are self-locking, which facilitates the movement of the device and improves its flexibility.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This tea processing spreading device uses a bidirectional threaded rod to rotate and drive a slider to slide horizontally along the inner wall of the mounting groove. The movement of the slider drives the spreading plate to move, thereby spreading the tea leaves. This not only reduces manual labor but also improves spreading efficiency.

[0014] 2. This tea processing spreading device uses a rotating shaft to drive the connecting bar to rotate. The connecting bar drives the hinge arm to rotate around the hinge point and pushes and pulls the slide bar, thereby causing the slide bar to slide back and forth along the inner wall of the limiting sleeve and drive the connecting plate to move. This causes the connecting plate to drive the frame and the screen plate to sway back and forth on the fixed plate, thereby screening the tea leaves spread on the screen plate and improving the tea processing efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0024] Please see Figure 1-4One embodiment of this utility model is as follows: a tea-spreading device for tea processing includes a base plate 1, two fixed plates 2 fixedly connected to the top of the base plate 1, a frame 3 slidably connected between the two fixed plates 2, a mesh plate 4 fixedly connected to the lower inner wall of the frame 3, a spreading mechanism 5 provided on the frame 3, and a sieving mechanism 8 provided on the fixed plates 2; the spreading mechanism 5 includes: an installation groove 51, which is opened on the left inner wall of the frame 3 and close to the top of the frame 3; a bidirectional threaded rod 52 is rotatably connected to the inner wall of the installation groove 51 via a bearing; sliders 53 are threadedly connected to the reverse threads of the bidirectional threaded rod 52 respectively, and the outer wall of each slider 53 is slidably connected to the inner wall of the installation groove 51; a spreading plate 54 is fixedly connected to the right side of each slider 53; a first motor 6 is connected to the front of the frame 3; and the front end of the bidirectional threaded rod 52 penetrates the frame. The frame 3 is fixedly connected to the output end of the first motor 6 via a coupling. By starting the first motor 6, the bidirectional threaded rod 52 can be driven to rotate. The rotation of the bidirectional threaded rod 52 drives the slider 53 to slide horizontally along the inner wall of the mounting groove 51. The movement of the slider 53 drives the spreading plate 54 to move, thereby spreading the tea leaves. This not only reduces manual labor but also improves the efficiency of spreading the tea leaves. The back of the frame 3 is open, and a slot is provided at the rear of the top of the frame 3. A baffle 7 is inserted into the slot. By pulling the baffle 7 upward, it is separated from the frame 3, making it convenient to collect the tea leaves. The bottom of the base plate 1 is connected to four casters 10. The four casters 10 are respectively connected to the four corners of the bottom of the base plate 1. The casters 10 are self-locking, which facilitates the movement of the device and improves its flexibility.

[0025] Working principle: Pour the tea leaves onto the mesh plate 4 of the frame 3. Start the first motor 6 to drive the bidirectional threaded rod 52 to rotate. The rotation of the bidirectional threaded rod 52 drives the slider 53 to slide horizontally along the inner wall of the mounting groove 51. The movement of the slider 53 drives the spreading plate 54 to move, thereby spreading the tea leaves on the spreading plate 54. By pulling the baffle 7 upward, the tea leaves are separated from the frame 3, making it convenient to recycle the tea leaves.

[0026] Please see Figure 1-4Based on the above embodiments, in another embodiment of this utility model, the screening mechanism 8 includes: a rotating shaft 81, which is rotatably connected to the right side of the left-side fixed plate 2 via a bearing; a connecting strip 82 is fixedly connected to the right end of the rotating shaft 81; a limiting sleeve 83 is fixedly connected to the right side of the fixed plate 2; a sliding strip 84 is slidably connected to the inner wall of the limiting sleeve 83; a hinge arm 85 is hinged to the front of the sliding strip 84, and the other end of the hinge arm 85 is hinged to the top of the connecting strip 82; a connecting plate 86 is fixedly connected to the back of the sliding strip 84, and the top of the connecting plate 86 is fixedly connected to the bottom of the frame 3. A second motor 9 is connected to the left side of plate 2. The left end of the rotating shaft 81 passes through the fixed plate 2 and is fixedly connected to the output end of the second motor 9 through a coupling. By starting the second motor 9, the rotating shaft 81 can be driven to rotate. The rotation of the rotating shaft 81 drives the connecting bar 82 to rotate. The connecting bar 82 drives the hinge arm 85 to rotate around the hinge point and pushes and pulls the slide bar 84, so that the slide bar 84 slides back and forth along the inner wall of the limiting sleeve 83 and drives the connecting plate 86 to move. This causes the connecting plate 86 to drive the frame 3 and the screen plate 4 to sway back and forth on the fixed plate 2, thereby screening the tea leaves spread on the screen plate 4 and improving the tea processing efficiency.

[0027] Working principle: The second motor 9 drives the rotating shaft 81 to rotate. The rotation of the rotating shaft 81 drives the connecting bar 82 to rotate. The connecting bar 82 drives the hinge arm 85 to rotate around the hinge point and push and pull the slide bar 84, so that the slide bar 84 slides back and forth along the inner wall of the limiting sleeve 83 and drives the connecting plate 86 to move. This causes the connecting plate 86 to drive the frame 3 and the screen plate 4 to sway back and forth on the fixed plate 2, thereby screening the tea leaves spread on the screen plate 4.

[0028] It is worth noting that the first motor 6 and the second motor 9 in the above embodiments are common devices in the prior art.
