Description

Technical Field

[0001] This invention belongs to the field of tea pruning and harvesting machinery technology, specifically relating to a tea tree pruning and harvesting device. Background Technology

[0002] With the continuous advancement of agricultural modernization, higher market demands are being placed on the mechanization of tea production: it's necessary to improve the level of mechanization while minimizing production costs and maximizing economic efficiency. Mechanizing the two most labor-intensive stages of tea tree pruning and harvesting has become a key approach and means to reduce production costs in tea gardens and alleviate labor shortages. Utilizing efficient pruning and harvesting equipment not only significantly improves operational efficiency and ensures timely harvesting of fresh leaves during the optimal picking period, but also facilitates stable tea production and promotes the large-scale and intensive development of the tea industry.

[0003] However, most existing mainstream tea tree pruning and harvesting equipment uses reciprocating cutting or rotating blade-based methods, extensively shearing or striking the tea tree canopy. While this method greatly improves harvesting efficiency, its inherent design usually makes it difficult to sort the tea leaves. Due to the difficulty in identifying the parts, in actual operation, tender buds, old leaves, and stems are often harvested together, resulting in severe mixing of raw materials. This significantly reduces the purity and consistency of the raw tea leaves, making subsequent processing extremely difficult.

[0004] Therefore, it is evident that developing a new type of tea tree pruning and harvesting equipment that can both ensure efficient tea picking and tea sorting is of great practical significance for improving the utilization rate of raw materials, reducing tea processing costs, and promoting the transformation of China's tea industry towards refinement and high quality. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect that the existing tea tree pruning and picking equipment usually does not have the function of tea sorting while ensuring the efficiency of tea picking, so as to provide a tea tree pruning and picking equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The main body includes a collection section, a harvesting section, and a stratification section. The harvesting section is movably connected to the collection section. Part of the stratification section is located inside the harvesting section, and part of the stratification section is located inside the collection section. The stratification section is separated into an upper channel and a lower channel. Multiple trimming parts are provided, and are respectively disposed on the ends of the harvesting section and the layering section away from the collecting section; The even spreading component includes a guide portion and a shaking portion integrally formed with the guide portion. The guide portion abuts against the lower inner side of the harvesting portion, and the shaking portion is movably connected to the collecting portion. A flipping component is located on the side of the spreading component away from the harvesting part. The collecting part is provided with a flipping groove, and the flipping component is rotatably disposed in the flipping groove. A first airflow component and a second airflow component are fixedly disposed in the upper channel and the second airflow component is fixedly disposed in the lower channel. The second airflow component is located downstream of the flipping component. A color sorter is located within the upper channel and is positioned downstream of the first airflow component; The first collector and the second collector are both connected to the upper channel and the lower channel. The first collector is located downstream of the second airflow component, and the second collector is located downstream of the first collector.

[0007] Preferably, the height of the shaking part gradually decreases along the direction away from the harvesting part, and the side of the shaking part facing the layering part is provided with a wavy groove.

[0008] Preferably, the flipping component includes a flipping shaft and a flipping plate fixed to the flipping shaft. The flipping shaft is rotatably connected to the collecting part. The flipping plate has a plurality of flipping grooves on its side facing away from the flipping shaft, and the curvature of the flipping grooves gradually increases along the direction away from the flipping shaft.

[0009] Preferably, the collecting section further includes an air outlet and a fine sorting outlet, both of which are located on the upper side of the collecting section, with the air outlet located downstream of the color sorter; the fine sorting outlet is located upstream of the first airflow component and is connected to the upper channel. The tea tree pruning and harvesting equipment also includes a filter screen installed in the collection section, and the filter screen covers the air outlet.

[0010] Preferably, a movable component is provided on the lower side of the main body in the vertical direction; The moving part includes a height adjustment part and a displacement part, and there are multiple height adjustment parts and displacement parts. The height adjustment part can reciprocate in the vertical direction and be stationary at a specific height. The height adjustment part is fixedly connected to the lower side of the main body. The displacement part is disposed on the lower side of the appropriate height part, and the displacement part is rotatably connected to the appropriate height part.

[0011] Preferably, one side of the collecting part is also provided with a retrieval port, which is correspondingly provided with the first collecting component and the second collecting component.

[0012] Preferably, the height of the side plate of the first collector near the airflow component is less than or equal to the height of the lower side of the lower channel, the height of the side plate of the first collector away from the airflow component is less than the height of the side plate of the first collector near the airflow component, and the height of the side plate of the second collector facing the airflow component is less than the height of the side plate of the first collector away from the airflow component.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The tea tree pruning and harvesting equipment provided in the above technical solution achieves efficient coordination of harvesting and sorting through the movable connection between the harvesting and collecting parts within the main body and the use of layered sections to separate upper and lower channels. During operation, the pruning component cuts the tea leaves, which are then drawn into the upper and lower channels by the first and second airflow components, respectively. The guiding part of the spreading component abuts against the harvesting part, and the shaking part is movably connected to the collecting part; the two components work together to vibrate and disperse the tea leaves, effectively preventing blockage in the lower channel. The rotating component in the turning trough throws the tea leaves back into the lower channel, allowing them to be smoothly transported by the airflow. As the tea leaves flow through the upper and lower channels, they fall into the first and second collecting components respectively, achieving initial sorting, due to the combination of airflow and their own gravity. A color sorter is installed in the upper channel and can further sort the tea leaves in conjunction with the airflow. The close cooperation of all components not only ensures efficient tea harvesting but also significantly improves the purity of the sorted leaves. Attached Figure Description

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] like Figures 1 to 4 As shown, the present invention provides a tea tree pruning and harvesting device. The device includes a main body 1, which serves as the supporting frame for the entire device and integrates a harvesting section 11, a layering section 12, and a collecting section 13. At the bottom of the main body 1, a movable component 2 is provided vertically to support the entire device and move it on the tea garden ground.

[0020] Specifically, the harvesting section 11 is the component that directly acts on the tea canopy surface. The harvesting section 11 and the collecting section 13 are connected by a flexible, extendable structure, named the adjusting component. This adjusting component allows the harvesting section 11 to bend at a certain angle and adjust its position relative to the collecting section 13. In actual operation, to adapt to different terrains and the shape of the tea canopy, the harvesting section 11 needs to have a flexible posture. Through the connection of the adjusting component, the harvesting section 11 can bend downwards at a certain angle, thus better conforming to the tea canopy surface and facilitating efficient harvesting of the tea leaves by the pruning component 111.

[0021] Multiple pruning elements 111 are provided on the harvesting section 11. These pruning elements 111 are the core components that perform physical cutting actions, and are usually reciprocating cutting blades or rotary cutter discs. The pruning elements 111 are respectively provided on the ends of the harvesting section 11 and the layering section 12 away from the collecting section 13. When the equipment moves in the tea garden, the pruning elements 111 move at high speed, cutting off the tender buds at the top of the tea tree as well as some old leaves and branches.

[0022] To accommodate tea trees of varying heights and ensure optimal harvesting results, the moving part 2 on the lower side of the main body 1 is designed with a height adjustment function. The moving part 2 includes a height adjustment section 21 and a displacement section 22. Multiple height adjustment sections 21 and displacement sections 22 are provided. The upper end of the height adjustment section 21 is fixedly connected to the lower side of the main body 1. The height adjustment section 21 uses a hydraulic cylinder, allowing it to reciprocate vertically and remain stationary at a specific height. By adjusting the height of the height adjustment section 21, the height of the main body 1 and the harvesting section 11 above the ground can be changed, thus adapting to the height of tea trees at different growth stages and ensuring that the pruning component 111 can accurately act on the optimal harvesting position. The displacement section 22 is located below the height adjustment section 21, specifically as wheels or tracks, and is rotatably connected to the height adjustment section 21. After the height adjustment section 21 is adjusted, the displacement section 22, driven by power, propels the equipment through the tea garden, enabling continuous operation.

[0023] The tea leaves cut by the trimmer 111 need to enter the equipment for further sorting under the influence of airflow. For this purpose, a stratification section 12 is provided inside the equipment. The stratification section 12 runs between the harvesting section 11 and the collecting section 13, with part of the stratification section 12 located within the harvesting section 11 and part within the collecting section 13. The main function of the stratification section 12 is to physically separate the internal space formed by the collecting section 13 and the harvesting section 11 into two independent channels: an upper channel 121 and a lower channel 122. The upper channel 121 is mainly used to transport the lighter, tender buds and leaves located on the upper side of the tea plant, while the lower channel 122 is mainly used to transport the heavier tea leaves located on the next upper side of the tea plant, as well as some chopped stems.

[0024] To generate airflow, a first airflow component 1211 is fixedly installed in the upper channel 121, and a second airflow component 1221 is fixedly installed in the lower channel 122. The first and second airflow components 1211 and 1221 are typically high-pressure fans or negative-pressure suction fans. During operation, the first and second airflow components 1211 and 1221 activate, generating strong suction in the upper and lower channels 121 and 122, respectively. The gas flow generated by the first and second airflow components 1211 and 1221 is in the same direction, and this gas flow direction is opposite to the direction of travel of the tea tree picking and pruning equipment. This reverse airflow design helps to quickly draw the cut tea leaves into the channels, preventing the tea leaves from accumulating at the cutting point and causing blockages, and provides the power basis for subsequent primary and secondary sorting.

[0025] During the initial picking and sorting process in the field, the lighter tea leaves cut from the upper side of the tea tree are directly sucked into the upper channel 121 by the suction force generated by the first airflow component 1211; while the heavier tea leaves cut from the lower side of the tea tree are sucked into the lower channel 122 by the airflow generated by the second airflow component 1221.

[0026] Because the lower channel 122 is located in the upper-middle part of the tea tree canopy, the amount of tea leaves sucked in is often large, and it contains a lot of old leaves, single leaves, and debris. In addition, the space in the lower channel 122 is relatively limited, and the tea leaves are prone to clogging in the channel. In order to effectively prevent this phenomenon, the present invention has designed a unique anti-clogging and initial sorting mechanism at the entrance and inside of the lower channel 122, mainly including a spreading component 131 and a turning component 132.

[0027] The evenly spreading component 131 includes a guide section 1311 and a vibrating section 1312, which are integrally formed. The guide section 1311 abuts against the lower inner side of the harvesting section 11, guiding the tea leaves into the lower channel 122. The vibrating section 1312 is movably connected to the collecting section 13 and is connected to a vibration motor, thus maintaining high-frequency vibration throughout the initial sorting process. Along the direction away from the harvesting section 11, the height of the vibrating section 1312 gradually decreases, forming an inclined guide surface. More importantly, a wavy groove 13121 is provided on the side of the vibrating section 1312 facing the layering section 12. When a large amount of tea leaves enter the lower channel 122 and fall onto the vibrating section 1312, the high-frequency vibration of the vibrating section 1312, in conjunction with the wavy groove 13121, can generate a strong shaking and tumbling effect on the accumulated tea leaves. This design can quickly disperse the tea leaves in the groove 13121, preventing them from clumping together, while using the height difference to make the tea leaves gradually move backward.

[0028] On the side of the spreading member 131 facing away from the harvesting section 11, downstream of the shaking section 1312, a turning member 132 is provided. The collecting section 13 has a turning groove 133, and the turning member 132 is rotatably disposed within the turning groove 133. The turning member 132 includes a turning shaft 1321 and a turning plate 1322 fixed to the turning shaft 1321. The turning shaft 1321 is rotatably connected to the collecting section 13 and rotates under the drive of a motor. The side of the turning plate 1322 facing the direction of rotation has multiple turning grooves 13221, and the curvature of the turning grooves 13221 gradually increases along the direction away from the turning shaft 1321. This curvature variation design is to better catch and scatter blades of different sizes. During operation, from the perspective of the attached drawings, the turning direction of the turning member 132 is clockwise. Some tea leaves on the groove 13121 of the spreading component 131 will slide into the area of ​​the flipping component 132 under the action of gravity and vibration, and fall into the flipping groove 13221 of the flipping plate 1322. As the flipping component 132 rotates clockwise in the flipping groove 133, the flipping groove 13221 gradually lifts the tea leaves that have been brought in, and after reaching a certain height, the tea leaves are thrown back into the depth of the lower channel 122 by centrifugal force and gravity. The strong airflow generated by the second airflow component 1221 blows the scattered tea leaves quickly towards the collection area behind.

[0029] After being dispersed by the vibration of the spreading component 131 and scattered by the turning component 132, the tea leaves entering the lower channel 122 become loose and are smoothly conveyed under the action of airflow, effectively avoiding blockage. At the same time, this process also achieves the initial loosening and grading of the tea leaves.

[0030] Subsequently, the tea leaves continue to move backward within the upper channel 121 and the lower channel 122. In the upper channel 121, a first airflow component 1211 provides the conveying power; in the lower channel 122, a second airflow component 1221 provides the conveying power. As the tea leaves flow through the upper and lower channels 121 and 122, combined with the effect of the airflow and their own gravity, they begin an initial sorting process based on the difference in gravity—a "free fall" type of separation. The principle is that the differences in volume and density between tender buds and older leaves result in different suspension velocities. With a constant airflow velocity, the heavier older leaves experience less lift and fall earlier; while the lighter tender buds experience stronger airflow and float a longer distance.

[0031] To facilitate this sorting principle, the equipment is equipped with a first collecting component 134 and a second collecting component 135. Both the first collecting component 134 and the second collecting component 135 are connected to the upper channel 121 and the lower channel 122. The first collecting component 134 is located downstream of the second airflow component 1221 and is mainly used to collect heavier, older leaves falling from the lower channel 122. The second collecting component 135 is located downstream of the first collecting component 134 and is mainly used to collect lighter, tender leaves floating in the upper channel 121, and also to collect some tender leaves that have drifted further away in the lower channel 122.

[0032] The height of the side plate of the first collecting component 134 near the second airflow component 1221 is less than or equal to the height of the lower side of the lower channel 122, so that the material in the lower channel 122 can fall in smoothly. The height of the side plate of the first collecting component 134 away from the second airflow component 1221 is less than the height of the side plate of the first collecting component 134 near the second airflow component 1221, forming a guide ramp to facilitate the material to slide in. The height of the side plate of the second collecting component 135 facing the second airflow component 1221 is less than the height of the side plate of the first collecting component 134 away from the second airflow component 1221. This staggered height difference design effectively physically separates the tea leaves at different landing points, achieving initial sorting. That is, most of the older leaves, due to their greater gravity, fall into the first collecting component 134 first; most of the younger leaves, due to their lesser gravity, float past the first collecting component 134 under the airflow and finally fall into the second collecting component 135.

[0033] Throughout the initial sorting process, the color sorter 1212 located in the upper channel 121 remains inactive. During this time, the end of the color sorter 1212 is always parallel to the gas flow direction, acting as a guide plate to minimize interference with the airflow and ensure smooth passage of the tea leaves. At this point, the initial picking and sorting are complete, and the equipment collects a large number of old and young leaves into the first collection unit 134 and the second collection unit 135, respectively.

[0034] Once the staff have transported the tea tree pruning and harvesting equipment and the tea leaves after the initial sorting back to their homes or processing plants, the second round of fine sorting can begin.

[0035] First, the staff operates the retrieval opening 139 located on the side of the collection section 13. The retrieval opening 139 corresponds to the first collection component 134 and the second collection component 135. The staff opens the retrieval opening 139 and removes the first collection component 134 and the second collection component 135, which are filled with tea leaves after the initial sorting. At this point, the first collection component 134 mainly contains older leaves, and the second collection component 135 mainly contains younger leaves, but both contain a certain amount of impurities or misselected leaves. To improve the purity of the tea, a second sorting is required. The staff then places the empty first collection component 134 and the empty second collection component 135 back into the retrieval opening 139 to receive the tea leaves after the second sorting.

[0036] Next, the secondary sorting operation is carried out. The fine sorting port 137 is sealed with a special cover throughout the initial sorting process to prevent external influences on the airflow intensity of the upper channel during the initial sorting. During the secondary sorting operation, the staff first opens the special cover of the fine sorting port 137 located on the upper side of the collection section 13 before proceeding with the subsequent steps of the secondary sorting operation. The fine sorting port 137 is located upstream of the first airflow component 1211 and is connected to the upper channel 121. Subsequently, the first airflow component 1211 and the color sorter 1212 are started. At this time, the second airflow component 1221 remains closed throughout the secondary sorting process, relying solely on the first airflow component 1211 for operation.

[0037] The staff slowly feeds the tea leaves after the initial sorting into the fine sorting port 137. The tea leaves fall from the fine sorting port 137 and first land on the upper side of the stratification section 12. Since only the first airflow component 1211 generates a strong suction at this time, the tea leaves are drawn upward into the channel 121 by the airflow generated by the first airflow component 1211 and flow at high speed through the color sorter 1212.

[0038] During this process, the color sorter 1212 begins to perform its core sorting function. This invention employs a color sorter that operates based on the optical properties of tea leaves for detection and rejection. When tea leaves pass through the detection area of ​​the color sorter 1212, photoelectric sensors detect the depth of color.

[0039] The specific sorting action is as follows: When the color sorter 1212 detects that the tea leaves are too light in color, the control system controls the actuator of the color sorter 1212 to deflect upward at a certain angle. This upward deflection lifts the tender tea leaves, changes the airflow trajectory of the leaves, and causes the leaves to drift a longer distance under the airflow, allowing them to pass over the first collector 134 and finally fall accurately into the second collector 135.

[0040] Conversely, when the color sorter 1212 detects that the tea leaves are too dark, the control system controls the end of the color sorter 1212 to deflect downwards at a certain angle. This downward deflection achieves the effect of pressing down the older tea leaves, forcing them to leave the airflow path earlier, thus causing them to drift a shorter distance under the airflow and fall into the first collection element 134 earlier.

[0041] By using the real-time dynamic deflection at the end of the color sorter 1212, combined with the stable airflow of the first airflow component 1211, high-precision secondary sorting of tea leaves is achieved. This sorting method is more accurate than simply relying on gravity sorting, effectively removing old leaves mixed in with tender leaves, as well as tender buds mixed in with old leaves, greatly improving the purity and quality consistency of the final raw materials.

[0042] In addition, to maintain internal air pressure balance and exhaust gas, the collection section 13 also includes an exhaust port 136. The exhaust port 136 is located on the upper side of the collection section 13 and downstream of the color sorter 1212. The airflow after color sorting, carrying dust and light impurities, eventually flows to the exhaust port 136 for discharge. To prevent light tea leaves from being discharged with the airflow, the tea tree pruning and harvesting equipment also includes a filter screen 138 installed within the collection section 13, which covers the exhaust port 136. The filter screen 138 effectively blocks tea leaves, allowing only gas and fine dust to escape, thus ensuring sorting efficiency while preventing raw material loss.

[0043] In summary, the tea tree pruning and harvesting equipment provided by this invention, through the precise cooperation of the components in the harvesting section 11, the stratification section 12, and the collection section 13, achieves a complete operational process of efficient harvesting in the field, initial gravity airflow sorting, and precise color sorting secondary sorting indoors. The equipment utilizes the counter-current airflow generated by the first airflow component 1211 and the second airflow component 1221, combined with the vibration dispersion of the wavy grooves 13121 of the spreading component 131 and the throwing and returning of the turning component 132, effectively solving the blockage problem of the lower channel 122 and achieving initial screening using gravity difference. Subsequently, high-precision selection is achieved by utilizing the deflection action at the end of the color sorter 1212, combined with the difference in airflow blowing distance. The close cooperation of all components not only ensures the efficiency of tea harvesting but also significantly improves the purity of sorting, meeting the needs of high-quality tea production.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
