Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea production technology, specifically to a tea production impurity removal device. Background Technology
[0002] In China, tea culture has a long history, and tea tasting is regarded as an elegant art. People cultivate their character and exchange emotions through brewing and tasting tea. Tea has become a bridge for communication between people. During the picking, processing and transportation of tea, various impurities inevitably get mixed in. These impurities affect the appearance and hygiene quality of the tea. Therefore, it is necessary to use impurity removal devices to remove impurities from the tea leaves, thereby improving the purity of the tea.
[0003] Existing devices have some drawbacks in use. For example, when removing impurities from tea leaves, the tea leaves tend to form a dense accumulation layer on the screen. The screen can only separate the tea leaves that come into contact with its surface, while the tea leaves and impurities inside the accumulation layer are difficult to remove effectively. The accumulated tea leaves hinder the free movement of impurities, making it even more difficult to separate the impurities located inside the tea pile. This results in a certain amount of impurities remaining in the tea leaves even after multiple sieving processes, affecting the purity and quality of the tea. Utility Model Content
[0004] The purpose of this invention is to provide a tea production impurity removal device that solves the problem that when existing impurity removal devices remove impurities from tea leaves, the tea leaves easily form a dense accumulation layer on the screen.
[0005] This utility model provides the following technical solution: a tea production impurity removal device, including a base, springs fixedly connected to the four corners of the upper surface of the base, support columns fixedly connected to the tops of the four springs, and a shell fixedly connected to the tops of the four support columns. A U-shaped screen is fixedly connected to the inner side of the shell, and vibration motors are fixedly connected to both sides of the lower surface of the shell, with two vibration motors symmetrically arranged. An auxiliary component for removing impurities from tea is provided on the shell.
[0006] In the above scheme, the vibration of the vibrating motor can drive the entire screening system to generate high-frequency vibration, which makes the tea leaves move and separate quickly on the U-shaped screen. The vibration can more effectively separate the impurities attached to the tea leaves, improving the thoroughness and efficiency of impurity removal. The screening effect of tea impurities can be improved by auxiliary components.
[0007] As a preferred embodiment of the above technical solution, a feed hopper is fixedly connected to one side of the upper end face of the outer shell, a discharge hopper is fixedly connected to the lower end face of the outer shell, a first outlet is opened on one side of the outer wall of the outer shell, a second outlet is opened on the outer wall of the U-shaped screen near the first outlet, and a discharge slide plate is fixedly connected to one side of the outer wall of the outer shell below the first outlet.
[0008] In the above solution, the tea leaves to be processed can be poured into the U-shaped screen inside the outer shell through the feeding hopper. Smaller impurities and broken leaves fall into the space below through the U-shaped screen and are smoothly discharged through the discharge hopper. This effectively separates the tea leaves from the impurities, ensuring the purity and quality of the tea leaves. The screened tea leaves are smoothly discharged along the discharge slide.
[0009] As a preferred embodiment of the above technical solution, the upper surface of the base is provided with a placement groove, a collection box is slidably connected to the inner side of the placement groove, and a handle is fixedly connected to the outer wall of one side of the collection box.
[0010] In the above scheme, the placement groove on the upper surface of the base provides a stable storage position for the collection box. During the screening process, smaller impurities, broken leaves, etc. fall into the collection box below through the U-shaped screen. This design makes the collection of impurities and broken leaves very convenient, avoids these substances from scattering inside or around the device, and maintains the cleanliness and hygiene of the working environment.
[0011] As a preferred embodiment of the above technical solution, the auxiliary component includes a mounting frame fixedly connected to one side of the housing. A motor is fixedly connected to the outer wall of the mounting frame on the side away from the housing. A rotating shaft is fixedly connected to the output end of the motor. The side of the rotating shaft away from the motor passes through the mounting frame and is rotatably connected to the mounting frame. A drive drive wheel is fixedly sleeved on the outer side of the end of the rotating shaft away from the motor. A driven drive wheel is provided on one side of the drive drive wheel. A connecting shaft is rotatably sleeved on the inner side of the driven drive wheel. The end of the connecting shaft near the housing is fixedly connected to the housing.
[0012] In the above scheme, the motor directly drives the rotating shaft to drive the active transmission wheel, which reduces energy loss during transmission and improves energy utilization efficiency.
[0013] As a preferred embodiment of the above technical solution, the auxiliary component includes an eccentric protrusion fixedly connected to the outer wall of one side of the driven transmission wheel. A first connecting rod is rotatably sleeved on the outer side of the eccentric protrusion. A second connecting rod is rotatably connected to the end of the first connecting rod away from the eccentric protrusion. A first transmission shaft is rotatably sleeved on the inner side of the end of the second connecting rod away from the first connecting rod. The end of the first transmission shaft away from the second connecting rod passes through the outer wall of one side of the outer shell and the U-shaped screen and is rotatably connected to the outer wall of one side of the outer shell and the U-shaped screen. A second transmission shaft is rotatably connected to the inner wall of one side of the U-shaped screen. A swing rod is fixedly sleeved on the outer side of both the first and second transmission shafts. A lever is fixedly connected to the inner walls of the opposite sides of the swing rod.
[0014] In the above scheme, the deflector helps the tea leaves to be more fully dispersed during the sieving process, thereby improving the uniformity and efficiency of sieving.
[0015] As a preferred embodiment of the above technical solution, a belt is fitted around the outer sides of the active drive wheel and the driven drive wheel, and the active drive wheel is driven by the belt to the driven drive wheel.
[0016] In the above scheme, belt drive has the characteristic of smooth transmission. Due to the softness and elasticity of the belt, it can reduce the impact and vibration during the transmission process, thereby ensuring the smooth transmission of power from the driving pulley to the driven pulley.
[0017] As a preferred embodiment of the above technical solution, the U-shaped screen is inclined.
[0018] In the above scheme, the inclined U-shaped screen helps the tea leaves to flow naturally on the U-shaped screen, reducing the retention of materials on the U-shaped screen and thus improving the screening efficiency.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] In this invention, a series of mechanical structures, including a motor driving a rotating shaft, a drive wheel, a belt, a driven wheel, and an eccentric protrusion, are used to realize the reciprocating motion of the paddle. This motion helps to break up the accumulated layers of tea leaves, allowing the tea leaves to be more fully dispersed during the sieving process, thereby improving the sieving efficiency and purity of the tea leaves.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] Example
[0028] like Figures 1-4As shown, this utility model provides a technical solution: a tea production impurity removal device, including a base 10, with springs 11 fixedly connected to the four corners of the upper surface of the base 10, support columns 12 fixedly connected to the tops of the four springs 11, and outer shells 13 fixedly connected to the tops of the four support columns 12. A U-shaped screen 14 is fixedly connected to the inner side of the outer shell 13, and vibration motors 15 are fixedly connected to both sides of the lower surface of the outer shell 13, with two vibration motors 15 symmetrically arranged. An auxiliary component 4 for assisting in tea impurity removal is provided on the outer shell 13. The screen 14 is inclined. A feed hopper 20 is fixedly connected to one side of the upper end face of the outer shell 13, and a discharge hopper 21 is fixedly connected to the lower end face of the outer shell 13. A first outlet 22 is opened on one side of the outer wall of the outer shell 13. A second outlet 23 is opened on the outer wall of the U-shaped screen 14 near the first outlet 22. A discharge slide plate 24 is fixedly connected to one side of the outer wall of the outer shell 13 below the first outlet 22. A placement groove 30 is opened on the upper end face of the base 10. A collection box 31 is slidably connected to the inside of the placement groove 30. A handle 3 is fixedly connected to one side of the outer wall of the collection box 31. 2. In actual use, the vibration motor 15 is started. The vibration motor 15 will start working and transmit vibration to the outer shell 13 and the U-shaped screen 14 through the spring 11 and the support column 12, causing the U-shaped screen 14 to shake. The tea to be processed is poured into the U-shaped screen 14 inside the outer shell 13 through the feed hopper 20. The tea is screened along the inclined U-shaped screen 14. During the screening process, larger tea particles will remain above the U-shaped screen 14, while smaller impurities, broken leaves, etc. will fall into the space below through the U-shaped screen 14 and be discharged. The hopper 21 discharges into the collection box 31, while the sieved tea leaves are discharged through the second outlet 23 and the first outlet 22 and along the discharge slide plate 24 for subsequent steps. During the process of sieving tea leaves to remove impurities using the U-shaped screen 14, the auxiliary component 4 can improve the sieving effect of tea impurities. After sieving is completed, the vibration motor 15 and the auxiliary component 4 are turned off, and the collection box 31 is pulled out from the placement trough 30 by the handle 32. The impurities in the collection box 31 are poured into the designated position. After the collection box 31 is emptied, it is put back into the placement trough 30.
[0029] As one implementation method in this embodiment, such as Figure 1 and Figure 4As shown, the auxiliary component 4 includes a mounting frame 401 fixedly connected to one side of the housing 13. A motor 402 is fixedly connected to the outer wall of the mounting frame 401 away from the housing 13. A rotating shaft 403 is fixedly connected to the output end of the motor 402. The side of the rotating shaft 403 away from the motor 402 passes through the mounting frame 401 and is rotatably connected to the mounting frame 401. A drive transmission wheel 404 is fixedly sleeved on the outer side of the end of the rotating shaft 403 away from the motor 402. A driven transmission wheel 405 is provided on one side of the drive transmission wheel 404. A connecting shaft 406 is rotatably sleeved on the inner side of the driven transmission wheel 405. 406 is fixedly connected to the outer casing 13 at one end. The auxiliary component 4 includes an eccentric protrusion 407 fixedly connected to the outer wall of one side of the driven transmission wheel 405. A first connecting rod 408 is rotatably sleeved on the outer side of the eccentric protrusion 407. A second connecting rod 409 is rotatably connected to the end of the first connecting rod 408 away from the eccentric protrusion 407. A first transmission shaft 410 is rotatably sleeved on the inner side of the end of the second connecting rod 409 away from the first connecting rod 408. The end of the first transmission shaft 410 away from the second connecting rod 409 passes through one side of the outer wall of the outer casing 13 and the U-shaped screen 14 and is connected to the outer casing 13 and the U-shaped screen. One side of the outer wall of the U-shaped screen 14 is rotatably connected, and the inner side of the U-shaped screen 14 is rotatably connected to the second drive shaft 411. A swing rod 412 is fixedly sleeved on the outer side of both the first drive shaft 410 and the second drive shaft 411. A lever 413 is fixedly connected to the inner walls of the opposite sides of the swing rod 412. A belt 50 is sleeved on the outer side of the driving drive wheel 404 and the driven drive wheel 405. The driving drive wheel 404 is driven by the driven drive wheel 405 via the belt 50. In actual use, the motor 402 drives the rotating shaft 403 to rotate the driving drive wheel 404. The driving drive wheel 404 is driven by the belt 50. Power is transmitted to the driven transmission wheel 405, causing it to rotate. As the driven transmission wheel 405 rotates, the eccentric protrusion 407 on its outer side rotates as well. The movement of the eccentric protrusion 407 is transmitted to the first transmission shaft 410 through the first connecting rod 408 and the second connecting rod 409, causing the first transmission shaft 410 to oscillate back and forth. The oscillation of the first transmission shaft 410 will drive the swing rod 412, which is fixedly connected to it, to move. The movement of the swing rod 412 will drive the paddle plate 413 to perform a back and forth paddle action, thereby helping the tea leaves to be more fully dispersed during the sieving process.
[0030] Working principle: When the vibration motor 15 is started, it transmits vibration to the outer casing 13 and the U-shaped screen 14 via the spring 11 and support column 12, causing the U-shaped screen 14 to vibrate. The tea leaves to be processed are poured into the U-shaped screen 14 inside the outer casing 13 through the feed hopper 20. The tea leaves are sieved along the inclined U-shaped screen 14. Larger tea particles remain above the U-shaped screen 14, while smaller impurities and broken leaves fall through the U-shaped screen 14 into the space below and are discharged into the collection box 31 through the discharge hopper 21. Simultaneously, the motor 402 drives the rotating shaft 403 to rotate the drive wheel 404. The drive wheel 404 transmits power to the driven wheel 405 via the belt 50, causing the driven wheel 405 to also rotate. When the driven wheel 405 rotates, its outer side... The eccentric protrusion 407 rotates accordingly. The movement of the eccentric protrusion 407 is transmitted to the first drive shaft 410 through the first connecting rod 408 and the second connecting rod 409, causing the first drive shaft 410 to oscillate back and forth. The oscillation of the first drive shaft 410 will drive the swing rod 412, which is fixedly connected to it, to move. The movement of the swing rod 412 will drive the paddle plate 413 to perform a back and forth paddle action, thereby helping the tea leaves to be more fully dispersed during the sieving process. The sieving tea leaves are discharged through the second outlet 23 and the first outlet 22 and along the discharge slide plate 24 for subsequent steps. After the sieving is completed, the vibration motor 15 and the motor 402 are turned off. The collection box 31 is pulled out from the placement trough 30 by the handle 32, and the impurities in the collection box 31 are poured into the designated position. After the collection box 31 is emptied, it is put back into the placement trough 30.
[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
