Description

Technical Field

[0001] This invention relates to the field of automated tea harvesting, specifically to an automated tea harvesting device and method suitable for mountainous and hilly areas. Background Technology

[0002] Tea is made from the newly grown buds or leaves of tea trees. These newly picked buds or leaves are called tea leaves. The manufacturing process includes withering, fermentation, fixation, rolling, and drying. After the tea is finished, it can undergo some refining processes to make its appearance more beautiful and its quality more stable. It can also undergo some processing to make it more diversified. In today's society, for high-grade teas that are scarce, manual picking is mostly used, while for medium-grade and low-grade mass-market teas that are more abundant, mechanized picking is mostly used.

[0003] Chinese patent CN215601984 U discloses a handheld tea picking device. The device uses a motor to drive a turntable to rotate, which in turn drives a cutting blade to reciprocate through a transmission rod. The cutting blade and the cutting edge work together to cut and pick the tea leaves. The picked tea leaves are collected in a collection bin and a storage box. An air pump sucks the tea leaves into the storage box for easy packaging. The picked tea leaves are also swept into the collection bin by a collection roller and a collection bar.

[0004] In summary, the aforementioned device uses a cutting blade to feed the tea leaves into a storage bin during the tea picking process. Subsequent processing requires workers to categorize the tea leaves by size, increasing their workload. Furthermore, the tea leaves themselves retain moisture during picking, and prolonged storage in the bin can easily lead to heat generation and mold growth, thus affecting the overall processing quality. Summary of the Invention

[0005] Based on this, the purpose of this invention is to provide an automated tea picking device and method suitable for mountainous and hilly areas, in order to solve the technical problems that after picking, the classification of tea leaves by size increases the workload of workers, and that tea leaves piled up in storage boxes for a long time are prone to heating and mold, which will affect the overall processing quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated tea harvesting device suitable for mountainous and hilly areas, comprising a frame, a feeding mechanism rotatably disposed within the frame, and a series of air holes penetrating the feeding mechanism; a rotating component rotatably disposed inside the feeding mechanism; a drying component installed at the bottom of the rotating component within the feeding mechanism; a cutting component disposed at one end of the feeding mechanism within the frame, and a screening frame disposed at the other end of the feeding mechanism; a screening plate installed within the screening frame; a first transmission mechanism meshing with a bevel gear on one side of the feeding mechanism, and a special-shaped gear connected to the other end of the first transmission mechanism; a gear ring cooperating with the special-shaped gear installed on one side of the screening frame, and tooth blocks symmetrically disposed vertically within the gear ring.

[0007] By adopting the above technical solution, the rotating component is driven to rotate rapidly under the action of the second transmission mechanism. At this time, the tea leaves on the feeding mechanism will be shaken back and forth, so that the tea leaves are evenly spread on the top of the feeding mechanism. With the cooperation of the drying component, the moisture on the tea leaves is dried. During this process, it is ensured that the tea leaves in the subsequent storage box can be stored for a long time without mold. Under the action of the special gear and gear ring, the sieve frame slides back and forth to sieve the material. Under the action of the sieve plate, the size of the tea leaves is sorted and classified at the same time as picking and feeding.

[0008] The present invention is further configured such that the rotating assembly includes a rotating shaft, rotating blades, slots, baffles and limiting plates. An array of rotating blades is uniformly arranged on the outer wall of the rotating shaft, and slots are opened on each rotating blade. A baffle is rotatably arranged in the slot, and a limiting plate that cooperates with the baffle is installed on the rotating blade.

[0009] By adopting the above technical solution, during the conveying process of the feeding mechanism, the rotating component itself rotates counterclockwise. As the rotating shaft drives the rotating blade to rotate counterclockwise, the limiting plate causes one side of the baffle to be in a closed state and the other side of the baffle to be in an open state. At this time, rotating the closed baffle upwards can throw some of the heat of the drying component upwards, while rotating the open baffle downwards allows the heat of the drying component to pass through the slot. This process does not affect the normal flow of heat on one side, thereby further improving the drying effect on the tea.

[0010] The present invention is further configured such that a spur bevel gear is provided on one side of the feeding mechanism, and a side bevel gear meshes with it on one side, and one side of the side bevel gear is connected to the first transmission mechanism.

[0011] By adopting the above technical solution, during the process of conveying tea leaves by the feeding mechanism, the spur bevel gear on one side will rotate. Through the meshing of the spur bevel gear and the side bevel gear, the first transmission mechanism will be driven to rotate.

[0012] The present invention is further configured such that telescopic frames are detachably provided on both sides of the frame, and rollers are hinged at the bottom of the telescopic frames.

[0013] By adopting the above technical solution, when harvesting tea trees in mountainous and hilly areas, if the road surface is relatively flat, workers can install a telescopic frame on both sides of the frame. By adjusting the height of the telescopic frame itself to adapt to the harvesting height of the tea trees, the frame can then be moved by the action of rollers, effectively reducing the harvesting burden on workers. When facing a more rugged road surface, workers can lift the frame by the handles and manually move the entire device, thus adapting it to different road surfaces and improving the overall practicality of the device.

[0014] The present invention is further configured such that a second transmission mechanism is connected to one side of the feeding mechanism, and a rotating component is connected to the other end of the second transmission mechanism, and the two sets of rotating components are connected to each other through a third transmission mechanism.

[0015] By adopting the above technical solution, during the process of conveying the harvested tea leaves by the feeding mechanism, the second transmission mechanism on one side will be driven to rotate, thereby realizing that the rotating components in the feeding mechanism will rotate accordingly. An array of rotating components is set in the feeding mechanism, which, under the action of the third transmission mechanism, drives the rotating components in the feeding mechanism to rotate together, thereby further improving the vibration frequency of the feeding mechanism itself.

[0016] The present invention is further configured such that the first transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by the transmission belt, one end of the side bevel gear is connected to the driving disc, and a special-shaped gear is connected to one end of the driven disc, and the diameter of the driving disc in the first transmission mechanism is larger than the diameter of its driven disc.

[0017] By adopting the above technical solution, the rotation of the side bevel gear will drive the drive disc to rotate as well. Under the action of the transmission belt, the driven disc will rotate, thereby realizing that the driven disc drives the special gear to rotate. Since the diameter of the drive disc in the first transmission mechanism is larger than the diameter of its driven disc, when the side bevel gear drives the drive disc to rotate several times, the driven disc will drive the special gear to rotate several times more times. This increases the shaking frequency of the screening frame itself and further improves the classification effect of tea.

[0018] The present invention is further configured such that handles are provided on both sides of the frame, and a rough surface is provided on the outer wall of the handle.

[0019] By adopting the above technical solution, the handle makes it easy for staff to lift the entire frame to a certain height. The rough surface increases the friction between the staff's hands and the handle, preventing the staff's hands from slipping during movement.

[0020] The present invention is further configured such that flexible discharge pipes are respectively connected to both sides of the screen frame at the position of the screen plate, and a storage box is connected to the other end of the flexible discharge pipe.

[0021] By adopting the above technical solution, the tea leaves will slide to both sides during the reciprocating shaking of the screening frame, thereby conveying them to the flexible discharge pipe and discharging them into the storage box for storage, reducing the collection burden of subsequent staff.

[0022] An automated tea-harvesting method suitable for mountainous and hilly areas includes the following steps:

[0023] Step 1: The staff moves the frame to the tea tree to be picked using the handle, then moves the frame to one side and cuts and picks the tea leaves using the cutting component. The picked tea leaves are then conveyed to one side by the feeding mechanism.

[0024] Step 2: During the rotation of the feeding mechanism, the rotating component will drive the feeding mechanism to reciprocate and shake. In this process, the tea leaves are evenly spread on the top of the feeding mechanism and dried in conjunction with the bottom drying component.

[0025] Step 3: The dried tea leaves will be conveyed into the sieve frame by the feeding mechanism. The size of the tea leaves will be sorted by the cooperation of the sieve frame and the sieve plate. The sorted tea leaves will then be conveyed to the storage box by the flexible discharge pipe.

[0026] By adopting the above technical solutions, tea leaves can be classified and screened during the picking process, reducing the screening burden on subsequent staff. Furthermore, the tea leaves can be dried during transportation to maintain their freshness and quality.

[0027] In summary, the present invention has the following main beneficial effects:

[0028] 1. This invention cuts tea leaves using a cutting component, then conveys the tea leaves to one side under the action of a feeding mechanism. Simultaneously, a second transmission mechanism drives a rotating component to rotate rapidly. At this time, the tea leaves on the feeding mechanism reciprocate and shake, achieving a uniform spread of the tea leaves on the top of the feeding mechanism. In conjunction with the drying component, the moisture on the tea leaves is dried. During this process, it ensures that the tea leaves in the subsequent storage box can be stored for a long time without mold, thus maintaining the freshness and quality of the tea leaves. At the same time, the rotation of the rotating component causes the feeding mechanism to shake, which also accelerates the air flow rate at the drying component, thereby further improving the drying effect of the tea leaves.

[0029] 2. This invention features a sieve frame elastically arranged on one side of the feeding mechanism within the frame, with a sieve plate installed inside the sieve frame. During the feeding process, the bevel gear meshes with the transmission mechanism, driving the shaped gear to rotate. Under the action of the shaped gear and the gear ring, the sieve frame slides back and forth to sieve the material. The sieve plate enables the tea leaves to be sorted by size while being picked and fed, greatly reducing the workload of subsequent workers. Furthermore, the sorted tea leaves are discharged into a storage box for collection via a flexible discharge pipe.

[0030] 3. This invention features a baffle mounted on the rotating blade. As the rotating shaft drives the rotating blade to rotate counterclockwise, a limiting plate causes one side of the baffle to be closed while the other side is open. Rotating the closed baffle upwards throws some of the heat from the drying assembly upwards, while rotating the open baffle downwards allows heat from the drying assembly to pass through the slot. This process does not affect the normal flow of heat on one side, thereby further improving the drying effect on the tea leaves. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] The embodiments of the present invention will now be described.

[0044] Example 1

[0045] An automated tea-picking device and method suitable for mountainous and hilly areas, such as Figures 1-8 As shown, the system includes a frame 1, handles 2, a feeding mechanism 9, a transmission mechanism, and a screening mechanism. Handles 2 are provided on both sides of the frame 1, and the outer wall of the handles 2 is provided with a rough surface. The handles 2 make it easy for the staff to lift the frame 1 to a certain height. The rough surface increases the friction between the staff's hands and the handles 2, preventing the staff's hands from slipping during the movement. Then the staff moves the frame 1. A cutting component 3 is provided at the front end of the frame 1. The cutting component 3 is used to cut the tea leaves. At the same time, the feeding mechanism 9 is rotated inside the frame 1. The feeding mechanism 9 is used to transport the cut tea leaves to one side.

[0046] Furthermore, a second transmission mechanism 18 is connected to one side of the feeding mechanism 9, and a rotating component 13 is connected to the other end of the second transmission mechanism 18. The two sets of rotating components 13 are connected by a third transmission mechanism 19. During the process of the feeding mechanism 9 conveying the harvested tea leaves, it will drive the second transmission mechanism 18 on one side to rotate, thereby enabling the rotating component 13 in the feeding mechanism 9 to rotate as well. At this time, the tea leaves on the feeding mechanism 9 will be shaken back and forth, so that the tea leaves are evenly spread on the top of the feeding mechanism 9. A drying component 14 is installed at the bottom of the rotating component 13 in the feeding mechanism 9. With the cooperation of the drying component 14, the moisture on the tea leaves is dried. During this process, it is ensured that the tea leaves in the subsequent storage box 4 can be stored for a long time without mold, so as to maintain the freshness and quality of the tea leaves. Since a set of rotating components 13 are set in the feeding mechanism 9, the rotating components 13 in the feeding mechanism 9 are driven to rotate together by the action of the third transmission mechanism 19, thereby further increasing the shaking frequency of the feeding mechanism 9 itself.

[0047] At the same time, while the rotating component 13 rotates and causes the feeding mechanism 9 to vibrate, it can also accelerate the air flow rate at the drying component 14, thereby further improving the drying effect on the tea. A sieve frame 5 is set at the other end of the feeding mechanism 9 in the frame 1. Since the top of the feeding mechanism 9 is set with a drop plate 8, and the discharge port of the drop plate 8 is located in the middle of the sieve frame 5, when the tea is conveyed to one side by the feeding mechanism 9, the tea is discharged downward through the drop plate 8, thereby realizing the discharge of the dried tea to the middle position of the top of the sieve plate 6. The sieve frame 5 is equipped with a sieve plate 6. The first transmission mechanism 12 is connected to one side of the feeding mechanism 9 by bevel gear meshing, and the other end of the first transmission mechanism 12 is connected with a special gear 20. A gear ring 15 that cooperates with the special gear 20 is installed on one side of the sieve frame 5, and tooth blocks are symmetrically set in the gear ring 15.

[0048] During the feeding process of the feeding mechanism 9, the bevel gear meshes with the first transmission mechanism 12 to drive the special gear 20 to rotate. Under the action of the special gear 20 and the gear ring 15, the screening frame 5 reciprocates and slides to screen the material. Under the action of the screen plate 6, the size of the tea leaves is screened and classified at the same time as the picking and feeding, which greatly reduces the workload of the subsequent staff. Flexible discharge pipes 7 are connected to both sides of the screening frame 5 at the position of the screen plate 6, and the other end of the flexible discharge pipe 7 is connected to the storage box 4. During the reciprocating shaking of the screening frame 5, the tea leaves slide to both sides, thereby conveying them to the flexible discharge pipe 7 and discharging them into the storage box 4 for storage, reducing the collection burden of the subsequent staff.

[0049] Please see Figure 4 A spur bevel gear 10 is provided on one side of the feeding mechanism 9, and a side bevel gear 11 is meshed on one side of it. One side of the side bevel gear 11 is connected to the first transmission mechanism 12. During the process of feeding tea leaves, the spur bevel gear 10 on one side will rotate. Through the meshing of the spur bevel gear 10 and the side bevel gear 11, the first transmission mechanism 12 will be driven to rotate.

[0050] Please see Figure 4 The first transmission mechanism 12 includes a driving disc, a transmission belt, and a driven disc. One end of the side bevel gear 11 is connected to the driving disc, and a special-shaped gear 20 is connected to one end of the driven disc. When the side bevel gear 11 rotates, it drives the driving disc to rotate as well. Under the action of the transmission belt, the driven disc rotates, thus enabling the driven disc to drive the special-shaped gear 20 to rotate. Since the diameter of the driving disc in the first transmission mechanism 12 is larger than the diameter of its driven disc, when the side bevel gear 11 drives the driving disc to rotate several times, the driven disc will drive the special-shaped gear 20 to rotate several times. This increases the shaking frequency of the screening frame 5 itself, further improving the classification effect of tea.

[0051] Example 2

[0052] like Figure 9 The diagram illustrates an automated tea-picking device and method suitable for mountainous and hilly areas. The overall structure is similar to that of Embodiment 1. The rotating assembly 13 includes a rotating shaft 1301, rotating blades 1302, slots 1303, baffles 1304, and limiting plates 1305. An array of rotating blades 1302 are evenly arranged on the outer wall of the rotating shaft 1301, and each rotating blade 1302 has a slot 1303. Baffles 1304 are rotatably arranged within the slots 1303, and limiting plates 1305 that cooperate with the baffles 1304 are installed on the rotating blades 1302. During the conveying process by the feeding mechanism 9, the rotating assembly 1302... 3. The rotating blade 1302 rotates counterclockwise as the rotating shaft 1301 drives it to rotate counterclockwise. Under the action of the limiting plate 1305, one side of the baffle 1304 is in a closed state, while the other side of the baffle 1304 is in an open state. At this time, rotating the closed baffle 1304 upwards can throw some of the heat of the drying component upwards, while rotating the open baffle 1304 downwards allows the heat of the drying component to pass through the slot 1303. This process does not affect the normal flow of heat on one side, thereby further improving the drying effect on the tea leaves and maintaining the freshness and quality of the tea leaves.

[0053] Example 3

[0054] like Figure 10The illustrated automated tea-picking equipment and method suitable for mountainous and hilly areas, based on Embodiment 2, features detachable telescopic frames 16 on both sides of the frame 1, with rollers 17 hinged to the bottom of the telescopic frames 16. When picking tea trees in mountainous and hilly areas, on relatively flat surfaces, workers can install the telescopic frames 16 on both sides of the frame 1 and adjust their height to suit the picking height of the tea trees. Then, the rollers 17 move the entire frame 1, effectively reducing the picking burden on workers. When facing more rugged surfaces, workers can lift the device using the handles 2 and manually move the entire device, thus adapting it to different terrains and improving the overall practicality of the device.

[0055] The working principle of this invention is as follows: When in use, the staff holds the handle 2 on both sides of the tea tree and then moves the frame 1. Under the action of the cutting component 3, the tea leaves are cut. The cut tea leaves are conveyed to one side through the action line of the feeding mechanism 9. At the same time, the feeding mechanism 9 rotates and, in cooperation with the second transmission mechanism 18, drives the rotating component 13 to rotate. At this time, the outer end of the rotating component 13 will repeatedly impact the feeding mechanism 9, causing the feeding mechanism 9 to shake. This ensures that the picked tea leaves are evenly spread on the top of the feeding mechanism 9. The tea leaves are then dried by the drying component 14, further ensuring the freshness and quality of the tea leaves.

[0056] Meanwhile, the dried tea leaves are conveyed to the sieve frame 5 by the feeding mechanism 9. The sieve frame 5 is equipped with a sieve plate 6. The feeding mechanism 9 drives the first transmission mechanism 12 to rotate through the meshing of bevel gears on one side. The first transmission mechanism 12 drives the special gear 20 to rotate. Under the action of the gear ring 15 on one side of the sieve frame 5, the sieve frame 5 is shaken back and forth to screen the tea leaves. Under the action of the sieve plate 6, the size of the tea leaves is screened and classified at the same time as picking and feeding, which greatly reduces the workload of the staff.

[0057] Although embodiments of the present invention have been shown and described, these specific embodiments are merely illustrative of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
