A vertical tea conveyor

Abstract

This invention discloses a vertical conveyor for tea processing, relating to the field of tea processing technology. The frame mechanism provides a path for the vertical circular movement of the transport mechanism, which in turn dries the tea. In this invention, during the tea drying process, after the tea leaves are placed into a channel formed by a sealing plate, the channel quickly closes to ensure a tight seal. Then, an electric vacuum pump is activated to evacuate the inside of the placement frame to a vacuum state, and two sets of hot air blowers are turned on to heat the filtered air. This allows the high-temperature hot air to circulate rapidly in a vacuum environment, agitating the tea leaves. The combination of vacuum and high-temperature hot air lowers the boiling point of water, allowing the moisture in the tea leaves to vaporize quickly. Furthermore, the strong hot air ensures the tea leaves are fully dispersed, preventing accumulation and significantly improving drying efficiency. The entire drying process is strictly monitored and short, enabling rapid drying of tea leaves during transport, greatly shortening the tea processing cycle, and improving equipment efficiency and production convenience.

Description

Technical Field

[0001] This invention relates to the field of tea processing technology, specifically a vertical conveyor for tea. Background Technology

[0002] Tea transportation is a crucial link in the tea production and processing process. Its efficiency and quality directly affect the final quality of the tea and production benefits. From the fresh tea leaves picked in the tea garden to each process in the processing workshop and then to the packaging stage, a safe, efficient and stable transportation system is needed to ensure the smooth flow of tea and reduce damage and quality deterioration. With the modernization of the tea industry, the requirements for tea transportation technology are increasing, prompting the industry to continuously explore and innovate.

[0003] In the tea processing industry, from the time the tea leaves are picked until the subsequent processing steps such as fixing, rolling and drying, they often need to go through multiple transfer and transportation processes. Traditional tea transportation methods mainly use horizontal or inclined conveyor belts, but these methods have significant drawbacks.

[0004] In the initial processing of fresh tea leaves, horizontal conveying is used, which not only occupies a large amount of factory floor space and greatly restricts the layout planning of other equipment and the optimization and adjustment of the production process, leading to increased production costs, but also makes the tea leaves easily damaged by slipping and piling during the conveying process, which has an adverse effect on the quality of the tea leaves. In addition, because the tea leaves themselves are relatively fragile, the existing conveying devices cannot carry out process-oriented processing of the tea leaves during transportation. This not only further increases costs, but also seriously reduces the overall processing efficiency of the tea leaves, making it difficult to meet the growing production needs and quality requirements of the tea processing industry. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, during the tea drying process, after the tea leaves are placed into the channel formed by the sealing plate, the channel can be quickly closed to ensure airtightness. Then, the electric vacuum pump is started to evacuate the inside of the placement frame to a vacuum state, and two sets of hot air blowers are turned on to heat the filtered air.

Compared with traditional horizontal or inclined conveyor belts, the floor space is greatly reduced, providing more space and possibilities for the equipment layout and production process optimization of the tea processing workshop, which helps to improve production efficiency and reduce production costs.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, refer to Figures 1-9 As shown: This invention provides a vertical tea conveyor, comprising: a support mechanism 1, a frame mechanism 2, and a transport mechanism 3;

[0035] The support mechanism 1 itself has stability, while the frame mechanism 2 is installed on one side of the outer wall of the support mechanism 1, thereby maintaining good stability for the tea during vertical conveying.

[0036] The frame mechanism 2 provides a path for the vertical circular movement of the transport mechanism 3, and in this process, it can keep multiple transport mechanisms 3 in a vertically stable state.

[0037] The function of the transport mechanism 3 is to vertically transport and process the tea. In this process, after the tea enters the transport mechanism 3, it falls on the top of the two receiving plates 37. Then, the electric vacuum pump 39 creates a vacuum inside the placement frame 34. Then, the hot air fan 362 is turned on to allow the high temperature hot air to circulate rapidly in the vacuum environment and fully contact the tea. The electric vacuum pump 39 continuously pumps air to make the moisture in the tea quickly vaporize and be discharged from the equipment, thus drying the tea.

[0038] The transport mechanism 3 includes two mounting beams 31;

[0039] Each of the two mounting beams 31 has an inner groove 311 on one side of its outer wall. A second miniature bearing 32 is fixedly inserted into the inner surface of each of the two inner grooves 311. A short rod 321 is fixedly inserted into the inner surface of each of the two second miniature bearings 32. Two crossbeams 33 are fixedly installed between opposite sides of the two mounting beams 31. A placement frame 34 is fixedly installed between the outer walls of the two short rods 321. A sealing plate 341 is rotatably connected inside the placement frame 34. An output pipe 342 is fixedly connected to the bottom of the placement frame 34. A switch valve 343 is installed on the outer wall of the output pipe 342. Two sets of damping frames 35 are fixedly connected to the outer wall of the placement frame 34, with the other end of each damping frame 35 fixedly connected to the bottom of the crossbeam 33. The inner surface of the placement frame 34 is fixed near the bottom. A counterweight 36 is fixedly connected, and a channel 361 is opened at the bottom center of the counterweight 36. Two sets of hot air blowers 362 are fixedly connected to the inner wall of the counterweight 36. Two support plates 37 are fixedly installed near the middle position of the inner wall of the placement frame 34. An outer annular frame 38 is fixedly connected between the outer walls of the two support plates 37. A set of rotating grooves 381 is preset inside the outer annular frame 38. Rotating blocks 382 are rotatably connected to the inner walls of the set of rotating grooves 381. An inner annular frame 383 is fixedly connected between the inner walls of the set of rotating blocks 382. A control plate 384 is fixedly connected to one side of the outer wall of the inner annular frame 383, and the outer wall of the control plate 384 rotatably penetrates the interior of the placement frame 34. An electric vacuum pump 39 is fixedly connected to the top of the placement frame 34.

[0040] In this embodiment, before the equipment is put into use, the support mechanism 1 should be firmly installed on the ground to ensure its stability. After the support mechanism 1, the frame mechanism 2, and the transport mechanism 3 are connected to each other, the equipment can be put into operation. When the external drive motor 14 is powered on and started, its output end begins to rotate, thereby driving a transmission gear 131 connected to it to rotate. Since the two transmission gears 131 and the chain 16 are in a meshing transmission state, and one connection point of the chain 16 is fixed to the linkage frame 26, while each set of inner rollers 22 rolls and rubs against the inner surface of the annular groove 211, the inner rod 221 will rotate inside the inner rollers 22, thereby driving the inner rod 221 and the linkage plate 23 fixed to its outer wall to move along the annular groove 211. 251 is installed inside the linkage frame 26. The linkage rod 25 rotates within the first miniature bearing 24 and the bearing body 251. The mounting plate 27 fixed on its other side is connected to the transport mechanism 3 as a connecting component, so that the transport mechanism 3 rotates with the chain 16. The bottom of the placement frame 34 is provided with a counterweight 36 to ensure that the center of gravity is at the bottom position. With the cooperation of the two short rods 321 rotating within the second miniature bearing 32, the placement frame 34 can always maintain a vertical downward state. At the same time, two sets of damping frames 35 are fixedly installed between the bottom of the crossbeam 33 and the outer wall of the placement frame 34. With their own characteristics, they effectively reduce the shaking of the placement frame 34 during movement and ensure the stability of operation. In the tea processing stage, the placement frame 34 is rotated. The inner sealing plate 341 forms a trough, through which workers place the freshly picked tea leaves into the placement frame 34. The tea leaves are supported by the two receiving plates 37 and the top of the outer annular frame 38. Then, the sealing plate 341 is rotated to close it with the placement frame 34, maintaining the airtightness of the placement frame 34. Next, the electric vacuum pump 39 is started to evacuate the vacuum level in the chamber to about 500-1000 Pa. Then, two sets of hot air blowers 362 are turned on. The hot air blowers 362 first introduce external air and filter out impurities, and then heat the air to 150℃-200℃. The high-temperature hot air circulates rapidly in the vacuum environment and blows the tea leaves, so that the tea leaves are fully dispersed on the two receiving plates 37, avoiding accumulation and improving drying efficiency. During this process, the electric vacuum pump 39 continues to operate. The continuous exhaust system causes the moisture in the tea leaves to rapidly vaporize and be expelled from the equipment. The entire drying process lasts for one minute under strict monitoring, achieving drying during the tea leaf conveying process. When the tea leaves need to be conveyed to the designated location, the operator rotates the control panel 384 90 degrees. With the cooperation of the rotating block 382 and the inner wall of the rotating groove 381, the opening between the outer annular frame 38 and the inner annular frame 383 faces upwards. At the same time, the air force of the hot air blower 362 is reduced. At this time, the tea leaves on the top of the two receiving plates 37 converge towards the middle of the plates under the action of gravity and fall through the opening to the top of the counterweight block 36. Since the counterweight block 36 is tilted downwards, the tea leaves will continue to converge towards its center and finally enter the output pipe 342 through the channel 361.After opening the switch valve 343 to connect the output pipe 342 with the counterweight 36, the processed tea leaves can be smoothly output, completing the tea leaf conveying process.

[0041] Example 2, according to Figures 1-2 as well as Figures 4-9 As shown, the frame mechanism 2 includes an annular plate 21. An annular groove 211 is provided on one side of the outer wall of the annular plate 21. Multiple sets of inner rollers 22 are rotatably connected to the inner surface of the annular groove 211. Inner rods 221 are rotatably connected inside the multiple sets of inner rollers 22. Linkage plates 23 are fixedly sleeved on the outer surface of the multiple sets of inner rods 221. Fixing grooves 231 are provided on one side of the outer wall of the multiple linkage plates 23. First miniature bearings 24 are fixedly inserted into the inner surface of the multiple fixing grooves 231. Linkage rods 25 are fixedly inserted into the inner surface of the multiple first miniature bearings 24. Bearing bodies 251 are fixedly sleeved on the outer surface of the multiple linkage rods 25. Linkage frames 26 are fixedly sleeved on the outer surface of the multiple bearing bodies 251. Mounting plates 27 are fixedly connected to one side of the outer wall of the multiple linkage rods 25. The outer side of the multiple mounting plates 27 is fixedly connected to one side of the outer wall of one of the multiple sets of mounting beams 31.

[0042] The transport mechanism 3 includes two mounting beams 31;

[0043] Each of the two mounting beams 31 has an inner groove 311 on one side of its outer wall. A second miniature bearing 32 is fixedly inserted into the inner surface of each of the two inner grooves 311. A short rod 321 is fixedly inserted into the inner surface of each of the two second miniature bearings 32. Two crossbeams 33 are fixedly installed between opposite sides of the two mounting beams 31. A placement frame 34 is fixedly installed between the outer walls of the two short rods 321. A sealing plate 341 is rotatably connected inside the placement frame 34. An output pipe 342 is fixedly connected to the bottom of the placement frame 34. A switch valve 343 is installed on the outer wall of the output pipe 342. Two sets of damping frames 35 are fixedly connected to the outer wall of the placement frame 34, with the other end of each damping frame 35 fixedly connected to the bottom of the crossbeam 33. The inner surface of the placement frame 34 is fixed near the bottom. A counterweight 36 is fixedly connected, and a channel 361 is opened at the bottom center of the counterweight 36. Two sets of hot air blowers 362 are fixedly connected to the inner wall of the counterweight 36. Two support plates 37 are fixedly installed near the middle position of the inner wall of the placement frame 34. An outer annular frame 38 is fixedly connected between the outer walls of the two support plates 37. A set of rotating grooves 381 is preset inside the outer annular frame 38. Rotating blocks 382 are rotatably connected to the inner walls of the set of rotating grooves 381. An inner annular frame 383 is fixedly connected between the inner walls of the set of rotating blocks 382. A control plate 384 is fixedly connected to one side of the outer wall of the inner annular frame 383, and the outer wall of the control plate 384 rotatably penetrates the interior of the placement frame 34. An electric vacuum pump 39 is fixedly connected to the top of the placement frame 34.

[0044] In this embodiment, initially, the sealing plate 341 rotates inside the placement frame 34, forming a path for the tea leaves to enter. Workers place the freshly picked tea leaves through this path inside the placement frame 34. The tea leaves are supported by the two receiving plates 37 and the top of the outer annular frame 38. After placement, the sealing plate 341 rotates again to close the placement frame 34, ensuring the placement frame 34 is sealed and preparing for subsequent vacuum processing. The electric vacuum pump 39 is started to evacuate the vacuum level in the chamber containing the placement frame 34 to approximately 500-1000 Pa, creating a vacuum environment. Two sets of hot air blowers 362 are then turned on. The hot air blowers 362 first introduce external gas and remove impurities using an internal filter, then heat the air to 150°C-200°C. The high-temperature hot air circulates rapidly in the vacuum environment and blows onto the tea leaves placed on the receiving plates 37, ensuring the tea leaves are fully dispersed and preventing accumulation. Under the strong hot air, the moisture in the tea leaves quickly vaporizes. The electric vacuum pump 39 continues to operate... The air is drawn out to expel the vaporized moisture from the equipment. The entire drying process is strictly monitored and lasts for one minute, achieving rapid drying during tea transportation and ensuring that the tea reaches a certain degree of dryness. When the tea needs to be transported to the appropriate position, the operator rotates the control plate 384 90 degrees. With the cooperation of the rotating block 382 and the inner wall of the rotating groove 381, the inner ring frame 383 rotates inside the outer ring frame 38 with both openings facing upwards. At the same time, the air force of the hot air blower 362 is reduced. The tea leaves on the top of the two receiving plates 37 converge towards the middle of the two plates under the action of gravity and fall onto the top of the counterweight block 36 through the opening. Since the counterweight block 36 is tilted downwards, the tea leaves will continue to converge towards its center. Finally, the tea leaves enter the interior of the output pipe 342 through the channel 361. The operator opens the switch valve 343 to connect the output pipe 342 with the counterweight block 36. The processed tea leaves are then smoothly output, completing the entire tea transportation process for subsequent processing or packaging.

[0045] Example 3, according to Figures 1-4 As shown, the frame mechanism 2 includes an annular plate 21. An annular groove 211 is provided on one side of the outer wall of the annular plate 21. Multiple sets of inner rollers 22 are rotatably connected to the inner surface of the annular groove 211. Inner rods 221 are rotatably connected inside the multiple sets of inner rollers 22. Linkage plates 23 are fixedly sleeved on the outer surface of the multiple sets of inner rods 221. Fixing grooves 231 are provided on one side of the outer wall of the multiple linkage plates 23. First miniature bearings 24 are fixedly inserted into the inner surface of the multiple fixing grooves 231. Linkage rods 25 are fixedly inserted into the inner surface of the multiple first miniature bearings 24. Bearing bodies 251 are fixedly sleeved on the outer surface of the multiple linkage rods 25. Linkage frames 26 are fixedly sleeved on the outer surface of the multiple bearing bodies 251. Mounting plates 27 are fixedly connected to one side of the outer wall of the multiple linkage rods 25. The outer side of the multiple mounting plates 27 is fixedly connected to one side of the outer wall of one of the multiple sets of mounting beams 31.

[0046] The support mechanism 1 includes a mounting base 11, a vertical beam 12 fixedly mounted on the top of the mounting base 11, a stabilizing beam 111 fixedly mounted between the mounting base 11 and one side of the outer wall of the vertical beam 12, two inner bearings 121 fixedly inserted inside the vertical beam 12, drive rods 13 fixedly inserted into the inner surface of each of the two inner bearings 121, transmission gears 131 fixedly connected to one side of the outer wall of each of the two drive rods 13, and drive motors 14 fixedly connected to the other side of the outer wall of each of the two drive rods 13, a motor plate 141 fixedly connected to the bottom of the drive motor 14, and one side of the outer wall of the motor plate 141 fixedly connected to one side of the outer wall of the vertical beam 12, two connecting plates 15 fixedly connected to the outer wall of the vertical beam 12, and one side of the outer wall of each of the two connecting plates 15 fixedly connected to one side of the outer wall of the annular plate 21, and a chain 16 meshing with the outer walls of the two transmission gears 131.

[0047] In this embodiment, before the equipment is put into use, the support mechanism 1 must be securely installed on the ground. After the support mechanism 1, frame mechanism 2, and transport mechanism 3 are successfully connected, the equipment can enter the operable state. When started, the output end of the external drive motor 14 starts to rotate after being powered on, thereby driving a transmission gear 131 connected to it to rotate synchronously. Since the two transmission gears 131 and the chain 16 mesh with each other, and one connection point of the chain 16 is fixed to the linkage frame 26, when each set of inner rollers 22 rolls and rubs against the inner surface of the annular groove 211, the inner rod 221 rotates inside the inner rollers 22, driving the inner rod 221 and the linkage plate 23 fixed to its outer wall to move along the path of the annular groove 211. Meanwhile, the bearing body 251 is installed inside the linkage frame 26, and the linkage rod 25 rotates within the first miniature bearing 24 and the bearing body 251. The mounting plate 27 on the other side is connected to the transport mechanism 3 as a receiving component. The transport mechanism 3 rotates with the rotation of the chain 16. A counterweight 36 is provided at the bottom of the placement frame 34 to ensure that the overall center of gravity is at the bottom. Furthermore, with the help of the rotation of the two short rods 321 within the second miniature bearing 32, the placement frame 34 can always maintain a vertical downward state. In addition, two sets of damping frames 35 are fixed between the bottom of the crossbeam 33 and the outer wall of the placement frame 34. With their own characteristics, they effectively reduce the shaking of the placement frame 34 when it moves, ensuring the stability of the equipment during operation.

[0048] The working principle of the entire mechanism is as follows: First, before the equipment is used, the support mechanism 1 is installed on the ground to maintain the stability of the support mechanism 1 itself. After the support mechanism 1, the frame mechanism 2 and the transport mechanism 3 are connected, the equipment can be operated.

[0049] When the external drive motor 14 is powered on, its output end can generate rotation to drive one of the transmission gears 131 to rotate. Because the two transmission gears 131 and the chain 16 are in a meshing transmission state, and one of the connection points of the chain 16 is fixed to the linkage frame 26, when each set of inner rollers 22 can roll and rub against the inner surface of the annular groove 211, and the inner rod 221 rotates inside the inner rollers 22, thereby driving the inner rod 221 and the linkage plate 23 fixed to one side of the outer wall to move along the path of the annular groove 211. The bearing body 251 is fixedly installed inside the linkage frame 26, and the linkage rod 25 rotates inside the first miniature bearing 24 and the bearing body 251. The mounting plate 27 is fixedly installed on the other side of the linkage rod 25, and the mounting plate 27 serves as a receiving component to realize the installation with the transport mechanism 3.

[0050] This causes the transport mechanism 3 to rotate along with the chain 16. Inside the placement frame 34, a counterweight 36 is set at its bottom to keep the center of gravity at the bottom. With the cooperation of the two short rods 321 rotating inside the second miniature bearing 32, the placement frame 34 can always maintain a vertical downward state. At the same time, two sets of damping frames 35 are fixedly installed between the bottom of the crossbeam 33 and the outer wall of the placement frame 34. Through the carrying effect of the damping frames 35, the shaking generated by the placement frame 34 during movement can be reduced, and its stability during movement can be maintained.

[0051] First, when the sealing plate 341 rotates inside the placement frame 34, it effectively forms a trough. Then, the worker can place the freshly picked tea leaves inside the placement frame 34. As the tea leaves enter the placement frame 34, they are effectively supported by the two receiving plates 37 and the top of the outer annular frame 38, maintaining the sealing of the placement frame 34. The sealing plate 341 rotates, closing the gap with the placement frame 34. At this point, the electric vacuum pump 39 is activated, raising the vacuum level inside the chamber to approximately 500-1000 Pa. Then, two sets of hot air blowers 362 are turned on. 2. External gas is introduced into the unit, and impurities in the gas are filtered out. The air is heated to 150℃-200℃, allowing the high-temperature hot air to circulate rapidly in a vacuum environment and blow upwards, making full contact with the tea leaves on the two receiving plates 37. The strong hot air can blow the tea leaves to disperse, thus preventing the tea leaves from piling up during the heating process and improving the drying efficiency. Meanwhile, the electric vacuum pump 39 continuously runs to extract air, causing the moisture in the tea leaves to quickly vaporize and be discharged from the equipment. The drying process is completed under strict monitoring, and this process lasts for one minute. The tea leaves can be dried during the conveying process.

[0052] After the tea leaves are transferred to the appropriate position, the operator rotates the control panel 384 90 degrees. With the rotating block 382 rotating between the inner walls of the rotating groove 381, the opening between the outer annular frame 38 and the inner annular frame 383 is kept facing upwards, and the airflow of the hot air blower 362 is reduced. Under the action of gravity, the tea leaves on the top of the two receiving plates 37 will converge towards the middle of the two plates and fall onto the top of the counterweight block 36 through the opening. Because the counterweight block 36 is set to a downward tilt, the tea leaves continue to converge towards the center of the counterweight block 36 and finally enter the interior of the output pipe 342 through the channel 361. After the connection between the output pipe 342 and the counterweight block 36 is achieved by the switch valve 343, the output of the processed tea leaves can be effectively maintained, realizing the conveying and processing of tea leaves.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
