Description

Technical Field

[0001] This utility model relates to the field of tea dust separation technology, and in particular to a tea dust separation device for Pu'er tea production. Background Technology

[0002] One step in the production of Pu'er tea is the separation of tea dust. This process involves separating tea leaves from tea dust (small particles produced during tea processing). This technique or device is crucial for improving the quality of tea products, ensuring the uniformity of the tea leaves, and enhancing the economic value of the tea.

[0003] Existing methods for separating tea dust typically involve manual labor, primarily using sieves to remove tea dust. This method has several drawbacks: low efficiency, high labor intensity, and prolonged operation can negatively impact workers' cervical and lumbar spine health. Manual sieving is not only inefficient but also generates significant dust during the process, severely affecting the working environment of the production workshop. Working in such an environment long-term poses a major threat to workers' health. Therefore, there is an urgent need to provide a tea dust separation device for Pu'er tea production to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the problems of low efficiency, high labor intensity, and large amount of powder in the above-mentioned existing technology of manually sifting tea dust with a sieve, which can easily cause adverse effects on the health of workers. This utility model provides a tea dust separation device for Pu'er tea production.

[0005] To solve the above-mentioned technical problems, the present invention provides a tea dust separation device for Pu'er tea production, including a device shell, a frame mechanism slidably connected inside the device shell, and a screen fixedly connected to the top of the frame mechanism.

[0006] A drive mechanism is fixedly connected to one side of the inner wall of the device housing. The top end of the drive mechanism is rotatably connected to the bottom end of the frame mechanism. A limit mechanism is fixedly connected to the inner bottom of the device housing. The top end of the limit mechanism is fixedly connected to the bottom end of the frame mechanism.

[0007] A cover plate is rotatably connected to the top of the device housing, and an anti-blocking mechanism is slidably connected to the bottom of the cover plate. A vibration mechanism is fixedly connected to one side of the inner wall of the device housing.

[0008] The present invention is further configured such that: a handle is fixedly connected to the top of the cover plate; a first inclined block is fixedly connected to the bottom of the inner wall of the device housing; an opening groove for dropping tea dust is provided at the bottom of the inner wall of the device housing; a collection box corresponding to the opening groove is fixedly connected to the bottom of the device housing; multiple support frames standing on the ground are fixedly connected to the bottom of the device housing; and multiple second inclined blocks are fixedly connected to one side of the inner wall of the device housing near the cover plate.

[0009] Through the above technical solution, the handle design allows the operator to easily rotate and open the cover to operate the device. The function of the first inclined block is to guide the tea dust to automatically slide into the opening groove when it falls to the bottom, and then slide into the collection box. The opening groove is designed to allow the screened tea dust to fall smoothly into it and then slide down. The collection box is used to collect these tea dust for easy management and processing. The main function of the support frame is to stabilize the outer shell of the device so that the operator can easily add or remove tea. The second inclined block prevents the tea from scattering from the gaps when the cover is opened and the tea to be screened is poured in, ensuring that the tea enters the screen correctly. These components together improve the convenience and efficiency of operation.

[0010] The present invention is further configured such that: the frame mechanism includes a screen frame fixedly connected around the screen mesh, two T-shaped blocks are fixedly connected to the bottom two sides of the screen frame respectively, and a square block is slidably connected to the outside of each of the two T-shaped blocks. Multiple rods are fixedly connected between the two square blocks, and the multiple rods are combined to form a quadrilateral. The two square blocks are located on the two sides of the quadrilateral respectively.

[0011] Through the above technical solution, the main function of the frame structure is to support the screen and screen frame, and ensure that the screen and screen frame can move up and down. The screen frame can slide smoothly on block one through T-blocks. At the same time, the two blocks one are fixedly connected together by rod one to ensure the stability of the overall structure without changing its basic function.

[0012] The present invention is further configured such that: the driving mechanism includes a first bracket fixedly connected to one side of the inner wall of the device housing, a motor is installed at the top of the first bracket, a shaft is fixedly connected to the output end of the motor, a second bracket is fixedly connected to the other side of the inner wall of the device housing, the other end of the shaft is rotatably connected to the second bracket, two rods are fixedly connected to the outside of the shaft, and rods are rotatably connected to the other ends of the two rods, and the two rods are respectively rotatably connected to the bottom ends of the two blocks.

[0013] Through the above technical solution, the function of the drive mechanism is to move the cube one up and down, creating a shaking motion to shake off the tea dust on the tea leaves. The motor is started by program control, which involves software control and is existing technology. After the motor starts, it will drive the shaft one to rotate, which in turn drives the rod two to rotate, causing the rod three to deflect and move, thereby moving the cube one up and down. This chain reaction causes the sieve frame and sieve screen to move up and down as well. Since the rod three is longer than the rod two, the rotation of the rod two can effectively deflect the rod three. When the rod two rotates to one end, the motor can rotate in the opposite direction, causing the rod two to rotate in the opposite direction. This cycle repeats. This design allows the sieve screen to shake quickly and conveniently, thereby rapidly separating the tea dust.

[0014] The present invention is further configured such that: the limiting mechanism includes a plurality of cylinders 1 fixedly connected to the bottom of the device housing, and each of the plurality of cylinders 1 is slidably connected to a shaft 2, the top ends of the plurality of shafts 2 being fixedly connected to the bottom ends of two blocks 1 respectively.

[0015] Through the above technical solution, the main function of the limiting mechanism is to ensure that block one can move up and down along the vertical direction and prevent it from deviating from the predetermined trajectory. When block one is driven to move up and down by rod three, block one simultaneously drives shaft two to move. Shaft two is located inside cylinder one and can slide up and down, thus accurately limiting and guiding block one. This design allows block one to slide vertically smoothly, ensuring the accuracy and stability of its movement.

[0016] The present invention is further configured such that: the anti-blocking mechanism includes two shafts three slidably connected to the center of the cover plate, each shaft three having a plate two fixedly connected to its top end, each shaft three having a spring sleeved on its exterior, each shaft three having a plate three fixedly connected to its bottom end, and each plate three having a plurality of columns one corresponding to the holes in the screen fixedly connected to its bottom end.

[0017] The purpose of the anti-clogging mechanism, as described above, is to keep the screen mesh clear and ensure the smooth separation of tea dust. When the screen mesh becomes clogged, pressing down on plate two causes shaft three on both sides to move downwards simultaneously. This action compresses the springs, and as shaft three descends, plate three also descends, pushing column one downwards to directly act on the screen mesh and clear the blockage. Once the pressure on plate two is released, the spring force causes plate three to return to its original position, simultaneously resetting column one and shaft three. This mechanism effectively prevents screen clogging and quickly clears the mesh, ensuring the continuity and efficiency of the tea dust separation process.

[0018] The present invention is further configured such that: the vibration mechanism includes a plate one fixedly connected to one side of the inner wall of the device housing, a plurality of balls one fixedly connected to the side of the plate one near the screen frame, and a ball two fixedly connected to the side of the screen frame near the plate one, and the plurality of balls one are distributed in a rectangular array.

[0019] Through the above technical solution, the main function of the vibration mechanism is to generate vibration when the screen frame moves up and down to enhance the separation effect of tea dust. When the screen frame moves in the vertical direction, ball two moves synchronously and collides with ball one during the movement. This collision generates oscillation, which helps to improve the vibration effect of the screen and thus more effectively separate tea dust. This mechanism improves the efficiency of tea dust separation and ensures the high efficiency of the separation process.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model uses a driving mechanism to make the screen vibrate up and down inside the device housing. This process effectively causes the tea leaves to jump up and down on the screen, thereby shaking off the tea dust attached to the surface of the tea leaves. During the vibration of the screen, ball two moves synchronously and collides with ball one, generating vibration. This not only enhances the separation effect of tea dust but also improves the separation efficiency. In addition, the design of this device helps to reduce the labor intensity of workers, while reducing the diffusion of dust in the air, reducing pollution to the working environment, and protecting the health of workers. Through these optimization measures, the device improves work efficiency while also taking into account environmental protection and occupational health.

[0022] 2. This utility model uses an anti-blocking mechanism to promptly clear clogged mesh holes on the screen, ensuring that the screen can continuously and efficiently separate tea dust and avoiding a decrease in separation effect due to screen hole blockage. This mechanism not only ensures the smoothness of the separation process, but is also simple to operate and highly practical, reflecting the optimization of the device in terms of function and operation.

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0035] Please see Figures 1-10 A tea dust separation device for Pu'er tea production includes a device shell 1. A frame mechanism 2 is slidably connected inside the device shell 1. A screen 3 is fixedly connected to the top of the frame mechanism 2. The frame mechanism 2 includes a screen frame fixedly connected around the screen 3. Two T-shaped blocks 201 are fixedly connected to the bottom two sides of the screen frame. A block 202 is slidably connected to the outside of each T-shaped block 201. Multiple rods 203 are fixedly connected between the two blocks 202. The multiple rods 203 are combined to form a quadrilateral. The two blocks 202 are located on the two sides of the quadrilateral. The main function of the frame structure is to support the screen 3 and the screen frame and ensure that the screen 3 and the screen frame can move up and down. The screen frame slides smoothly on the blocks 202 through the T-shaped blocks 201. At the same time, the two blocks 202 are fixedly connected together by the rods 203 to ensure the stability of the overall structure without changing its basic function.

[0036] like Figures 4-8As shown, a drive mechanism 4 is fixedly connected to one side of the inner wall of the device housing 1. The top end of the drive mechanism 4 is rotatably connected to the bottom end of the frame mechanism 2. The drive mechanism 4 includes a first bracket 401 fixedly connected to one side of the inner wall of the device housing 1. A motor 402 is mounted on the top end of the first bracket 401. A shaft 403 is fixedly connected to the output end of the motor 402. A second bracket 406 is fixedly connected to the other side of the inner wall of the device housing 1. The other end of the shaft 403 is rotatably connected to the second bracket 406. Two rods 404 are fixedly connected to the outside of the shaft 403. The other ends of the two rods 404 are rotatably connected to rods 405. The two rods 405 are rotatably connected to the bottom ends of two blocks 202 respectively. The function of the drive mechanism 4 is to move the blocks 202 up and down. The movement creates a shaking motion to shake off tea dust. Motor 402 is activated via program control; this part involves software control and is existing technology. After motor 402 starts, it drives shaft 403 to rotate, which in turn drives rod 404 to rotate, causing rod 405 to deflect. This, in turn, causes block 202 to move up and down. This chain reaction causes the sieve frame and sieve 3 to move up and down as well. Because rod 405 is longer than rod 404, the rotation of rod 404 effectively deflects rod 405. When rod 404 reaches one end, motor 402 can rotate in the opposite direction, causing rod 404 to rotate in the opposite direction. This cycle repeats continuously. This design allows the sieve 3 to shake quickly and easily, thus rapidly separating the tea dust.

[0037] like Figure 6 As shown, a limiting mechanism 5 is fixedly connected to the inner bottom of the device housing 1. The top end of the limiting mechanism 5 is fixedly connected to the bottom end of the frame mechanism 2. The limiting mechanism 5 includes multiple cylinders 501 fixedly connected to the inner bottom of the device housing 1. Each cylinder 501 has a shaft 502 slidably connected inside it. The top ends of the shafts 502 are fixedly connected to the bottom ends of two blocks 202 respectively. The main function of the limiting mechanism 5 is to ensure that the blocks 202 can move up and down in the vertical direction and prevent them from deviating from the predetermined trajectory. When the blocks 202 are driven to move up and down by the rod 405, the blocks 202 simultaneously drive the shafts 502 to move. The shafts 502 are located inside the cylinders 501 and can slide up and down. This provides precise limiting and guidance for the blocks 202. This design allows the blocks 202 to slide vertically smoothly, ensuring the accuracy and stability of their movement.

[0038] like Figure 1 , Figures 9-10As shown, a cover plate 6 is rotatably connected to the top of the outer casing 1 of the device, and an anti-blocking mechanism 7 is slidably connected to the bottom of the cover plate 6. The anti-blocking mechanism 7 includes two shafts 701 slidably connected to the center of the cover plate 6. A plate 702 is fixedly connected to the top of each shaft 701. A spring 703 is sleeved on the outside of each shaft 701. A plate 704 is fixedly connected to the bottom of each shaft 701. Multiple posts 705 corresponding to the holes in the screen 3 are fixedly connected to the bottom of the plate 704. The purpose of the anti-blocking mechanism 7 is to keep the mesh of the screen 3 unobstructed, ensuring the smooth separation of tea dust. When the mesh of screen 3 becomes clogged, pressing down on plate 2 (702) will cause shafts 3 (701) on both sides to move downwards simultaneously. This action compresses spring 703. As shafts 3 (701) descend, plate 3 (704) will also descend, pushing column 1 (705) downwards to directly act on the mesh of screen 3, thus clearing the blockage. Once the pressure on plate 2 (702) is released, the elasticity of spring 703 will cause plate 3 (704) to return to its original position, while simultaneously resetting column 1 (705) and shaft 3 (701). This mechanism effectively prevents screen 3 from becoming clogged and can quickly clear the mesh, ensuring the continuity and efficiency of tea dust separation.

[0039] like Figures 6-8 As shown, a vibration mechanism 8 is fixedly connected to one side of the inner wall of the device housing 1. The vibration mechanism 8 includes a plate 801 fixedly connected to one side of the inner wall of the device housing 1. A plurality of balls 802 are fixedly connected to the side of the plate 801 near the sieve frame. A plurality of balls 803 are fixedly connected to the side of the sieve frame near the plate 801. The plurality of balls 802 are arranged in a rectangular array. The main function of the vibration mechanism 8 is to generate vibration when the sieve frame moves up and down to enhance the separation effect of tea dust. When the sieve frame moves in the vertical direction, the balls 803 move synchronously and collide with the balls 802 during the movement. This collision generates oscillation, which helps to improve the vibration effect of the sieve 3, thereby separating tea dust more effectively. This mechanism improves the efficiency of tea dust separation and ensures the high efficiency of the separation process.

[0040] like Figure 1-3As shown in the figure, a handle is fixedly connected to the top of the cover plate 6, and a wedge 9 is fixedly connected to the bottom of the inner wall of the device housing 1. An opening slot 10 for dropping tea leaves is provided at the bottom of the inner wall of the device housing 1. A collection box 11 corresponding to the opening slot 10 is fixedly connected to the bottom of the device housing 1. Multiple support frames 12 are fixedly connected to the bottom of the device housing 1. Multiple wedges 13 are fixedly connected to one side of the inner wall of the device housing 1 near the cover plate 6. The handle design allows the operator to easily rotate and open the cover plate 6 to operate the device. The function of the wedge 9 is to collect tea leaves when they fall to the bottom. The inclined surface guides the tea dust to automatically slide into the opening groove 10 and then slide down into the collection box 11. The opening groove 10 is designed to allow the screened tea dust to fall smoothly into it and then slide down. The collection box 11 is used to collect these tea dust for easy management and processing. The main function of the support frame 12 is to stabilize the outer shell 1 of the device so that the staff can easily add or remove tea leaves inside. The inclined block 13 prevents the tea leaves from falling out of the gap when the cover plate 6 is opened and the tea leaves to be screened are poured in, ensuring that the tea leaves enter the screen 3 correctly. These components together improve the convenience and efficiency of operation.

[0041] In use, the cover plate 6 can be rotated and opened by operating the handle, allowing tea leaves to be separated to be poured into the outer casing 1. The inclined block 13 guides the tea leaves smoothly onto the screen 3. After starting the motor 402, the shaft 403 rotates, which in turn drives the rod 404 to rotate, causing the rod 405 to deflect. This series of actions causes the block 202 to slide up and down via the cylinder 501 and the shaft 502, thereby causing the screen 3 and screen frame to move up and down synchronously. This causes the tea leaves to vibrate up and down within the screen 3, shaking off any tea dust adhering to it. The reciprocating rotation of the motor 402 further enhances the... The separation effect of tea dust is enhanced by the movement of the sieve frame up and down, causing ball 2 803 to move accordingly and collide with ball 1 802 on plate 1 801, generating vibration and further strengthening the separation effect. If the mesh of sieve 3 becomes clogged, it can be resolved by pressing down plate 2 702. This action will drive shaft 3 701 and plate 3 704 to move downwards, aligning column 1 705 with the mesh of sieve 3 and clearing the blockage. Once plate 2 702 is released, the elasticity of spring 703 will cause plate 3 704 to automatically reset. This not only prevents sieve 3 from becoming clogged but also ensures ease of operation and practicality.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
