Description

Technical Field

[0001] This invention relates to the field of harvesting equipment technology, and in particular to a toothed comb-type harvester. Background Technology

[0002] Honeysuckle, a perennial semi-evergreen vine belonging to the Caprifoliaceae family, is a traditional and commonly used Chinese medicinal herb. It is also known as "silver flower" or "winter honeysuckle." The current Chinese Pharmacopoeia defines honeysuckle as "the dried flower buds or newly opened flowers of *Lonicera japonica*, a plant in the Caprifoliaceae family." Honeysuckle is not only a major traditional Chinese medicinal herb but also a plant used for both medicinal and edible purposes. Its medicinal and pharmacological functions include clearing heat and detoxifying, dispersing wind-heat, and antibacterial and antiviral effects. Many daily chemical products also use honeysuckle as a raw material. Furthermore, with the improvement of people's living standards, health foods and beverages made from honeysuckle have developed rapidly. With the increasing planting area of ​​honeysuckle and the continuous development of agronomy, manual harvesting of honeysuckle can no longer meet the economic and profit-seeking pursuit of farmers.

[0003] Currently, most honeysuckle harvesting devices on the market are handheld, with low levels of automation. They primarily assist manual harvesting and do not reduce labor intensity. They cannot operate efficiently and continuously, resulting in low harvesting efficiency and unsuitability for large-scale honeysuckle harvesting, thus hindering the development of the honeysuckle industry. Therefore, there is an urgent need to develop automated field machinery suitable for honeysuckle harvesting to reduce labor intensity, lower costs and increase efficiency for honeysuckle growers, and promote the large-scale development of the honeysuckle industry. Summary of the Invention

[0008] Preferably, both ends of the picking driven shaft are connected to the connecting frame through a tensioning mechanism. The output end of each tensioning mechanism is connected to the corresponding end of the picking driven shaft, and the output end of each tensioning mechanism can drive the end of the picking driven shaft to move away from the picking drive shaft.

[0009] Preferably, the frame of the machine is also provided with two transmission devices, each of which corresponds to one of the toothed belt comb devices. The transmission device has a total transmission surface, part of which is located below the toothed belt comb device on the corresponding side, and the output end of the total transmission surface is connected to and communicates with a collection box.

[0010] Preferably, the conveying device includes a first conveyor belt mechanism and a second conveyor belt mechanism. The first conveyor belt mechanism is disposed on the frame of the whole machine below the toothed comb brush device on the same side. The second conveyor belt mechanism is disposed between the first conveyor belt mechanism and the corresponding collection box. The collection box is higher than the first conveyor belt mechanism in the vertical direction. The first conveyor belt mechanism has a first conveying surface, and the second conveyor belt mechanism has a second conveying surface. The output end of the first conveying surface is connected to the input end of the second conveying surface, and the output end of the second conveying surface is connected and communicates with the collection box.

[0011] Preferably, two flower-grafting scale groups are rotatably provided within the harvesting gap. The two flower-grafting scale groups are arranged opposite to each other, and the gap between the two flower-grafting scale groups is used to clamp and fix the lower end of the harvested plant.

[0016] The present invention achieves the following technical effects compared to the prior art:

[0017] The toothed band brush harvester provided by this invention moves the equipment to the plant to be harvested via a walking system, allowing the harvested plant to pass through the harvesting gap in sequence. The machine self-propelledly straddles the plant. Two toothed band brush devices are symmetrically arranged in a "V" shape, meaning the gap between the two devices gradually narrows from front to back. The front section along the first direction forms a feeding inlet, facilitating the entry of the plant into the harvesting area. The plant within the harvesting gap is harvested by the picking teeth on the toothed band brush devices on both sides. The rotating comb brush applies increasing pressure to the harvested plants as the distance between the two toothed comb brush devices decreases, creating a brushing effect that is gentler at the front and more rigid at the back. Compared to the traditional method of applying a constant brushing force to the harvested plants, this improves harvesting efficiency and reduces damage to the branches, thus affecting next year's yield. The toothed comb brush devices, arranged in a "V" shape, create this gentle-at-the-front-and-rigid-at-the-back brushing effect, enabling automated, continuous, and highly efficient harvesting, while reducing labor intensity and labor costs.

[0018] Furthermore, the toothed belt comb device drives the picking drive shaft to rotate through the picking driver, which in turn drives the picking belt and the picking driven shaft to rotate. Its structure is simple and is a simplified conveyor belt structure. It can be completed by adding picking teeth to the existing conveyor belt structure, which is convenient for processing and reduces manufacturing costs.

[0019] Furthermore, the tensioning mechanism allows for adjustment of the tension of the picking belt, thereby regulating the brushing effect of the picking teeth on the harvested plants.

[0020] Furthermore, a conveyor device is used to collect the harvested materials from the plants and store them in their respective collection boxes, so as to achieve both harvesting and collection simultaneously, effectively improving the efficiency of large-scale harvesting and reducing the labor costs of harvesting.

[0021] Furthermore, by setting the collection box above the first conveyor belt mechanism, the vertical storage capacity of the collection box is increased while minimizing the space occupied by the length of the collection box in the first direction, thereby reducing the overall length of the equipment and improving its mobility and flexibility. Moreover, the first and second conveyor belt mechanisms can be used to collect the harvested materials into the collection box, which is simple, stable and reliable.

[0022] Furthermore, the two flower-catching scale plate groups have a conformal self-adaptive capability, meaning they can automatically adjust the position of the harvested plants within the harvesting gap through the elastic force of the elastic elements, adaptively adjusting for row deviations. This ensures that the toothed comb devices on both sides can evenly and effectively harvest the harvested plants within the harvesting gap. In addition, the two flower-catching scale plate groups can seal the lower end of the harvested plants, ensuring that the harvested material does not fall into the field through the gap after falling off, thus improving collection efficiency.

[0023] Furthermore, the flower-collecting scale assembly is designed with one side higher than the other, so that the harvested material can fall onto the flower-collecting scale assembly and automatically roll to the corresponding position by its tilt and its own weight, avoiding accumulation at the position where the harvested plant is held, thus improving the collection efficiency.

[0024] Furthermore, the branch gathering device can gather the harvested plants, thus facilitating the accurate introduction of the harvested plants into the harvesting gap for subsequent harvesting work.

[0025] Furthermore, the power system is installed on the frame to provide driving force, and the walking mechanism enables the equipment to move on its own. It has a high degree of integration, does not require traction equipment, and is more flexible and reliable.

[0026] Furthermore, by placing the cab on the front upper side of the machine frame, firstly, it can take into account the center of gravity of the equipment and ensure its stability; secondly, the cab being located at the front allows the driver to have a clearer and more intuitive view of the plants to be harvested, so as to align them with the harvesting gap and achieve high-efficiency and precise harvesting.

[0041] 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.

[0042] The purpose of this invention is to provide a toothed band comb harvester to solve the problems existing in the prior art, realize automated continuous and high-efficiency harvesting, and reduce the labor intensity and labor costs of workers.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Example 1

[0045] This embodiment provides a toothed comb-type harvester 100, mainly used for harvesting honeysuckle, but not limited to, other types of honeysuckle. Figures 1-5As shown, the machine includes a frame 10, a walking system, and a harvesting mechanism. The length direction of the frame 10 is taken as the first direction, and the width direction of the frame 10 is taken as the second direction. The first direction is perpendicular to the second direction and parallel to the traveling direction of the frame 10. A harvesting gap 11 extending through the first direction is provided at the bottom of the frame 10. The walking system is used to move the frame 10. The harvesting mechanism includes two toothed brush devices 20, each with a rotating harvesting belt 23. Multiple harvesting teeth 24 are fixed on the harvesting belt 23. The two harvesting belts 23 are symmetrically arranged on both sides of the harvesting gap 11. The sides of the two harvesting belts 23 closest to the entry end of the harvesting gap 11 are further apart in the second direction, while the sides of the two harvesting belts 23 furthest from the entry end of the harvesting gap 11 are closer together in the second direction.

[0046] The walking system moves the equipment to the harvested plants, allowing the plants to pass through the harvesting gap 11 in sequence. The equipment then self-propelledly straddles the plants. Two toothed brush devices 20 are symmetrically arranged in a "V" shape, with the gap between them gradually narrowing from front to back. The front section of the two devices forms a feeding inlet, facilitating the entry of the plants into the harvesting area. The plants within the harvesting gap 11 are rotated by the harvesting belts 23 with harvesting teeth 24 on the toothed brush devices 20 on both sides. The brushing force applied to the harvested plants gradually increases as the distance between the two toothed brush devices 20 decreases, creating a brushing effect that is gentler at the front and more rigid at the back. Compared to the traditional method of applying a constant brushing force to the harvested plants, this method improves harvesting efficiency and reduces damage to the branches of the harvested plants, thus affecting the yield of the following year. The toothed brush devices 20, arranged in a "V" shape, create a brushing effect that is gentler at the front and more rigid at the back, enabling automated, continuous, and highly efficient harvesting, while reducing the labor intensity and labor costs for workers.

[0047] Specifically, necessary shielding plates are installed on the machine frame 10 around the harvesting operation area at the harvesting interval 11 to ensure a closed effect, prevent the harvested materials from falling outside the harvesting operation area, and improve the collection effect.

[0048] Specifically, the "V" shape formed by the two toothed comb brush devices 20 has an inner angle of 20°, that is, one side is at a 10° angle to the forward direction.

[0049] Specifically, a temporary storage area for receiving harvested materials is provided on the machine frame 10 located on both sides of the harvesting gap 11 and below the toothed comb device 20.

[0050] Specifically, the temporary storage area can be a directly set plane or a cavity. The plane can be formed by the upper surface of a flat plate, and the cavity can be formed by welding together a plate structure. The temporary storage area can also be an automatic convergence mechanism formed by a first transmission belt mechanism and a second transmission belt mechanism 42 and a corresponding collection box 50 to realize the automatic collection of the harvested materials.

[0051] In the optional solutions of this embodiment, the more preferred one is shown in the figure. Figures 3-5 As shown, the toothed belt comb device 20 includes a picking driver, a picking drive shaft 21, a picking driven shaft 22, and a picking belt 23; a connecting frame 12 for mounting the toothed belt comb device 20 is provided on the machine frame 10; the axis of the picking drive shaft 21 and the axis of the picking driven shaft 22 are parallel and both are parallel to the horizontal plane; both ends of the picking drive shaft 21 and the picking driven shaft 22 are rotatably mounted on the connecting frame 12; the picking belt 23 is sleeved on the outside of the picking drive shaft 21 and the picking driven shaft 22; the picking driver is used to drive the picking drive shaft 21 to rotate; the distance between the end of the picking drive shaft 21 near the entry end of the harvesting gap 11 and the harvesting gap 11 in the second direction is greater than the distance between the end of the picking drive shaft 21 away from the entry end of the harvesting gap 11 and the harvesting gap 11 in the second direction. The toothed belt comb device 20 drives the picking drive shaft 21 to rotate through the picking driver, which in turn drives the picking belt 23 and the picking driven shaft 22 to rotate. Its structure is simple and is a simple conveyor belt structure. It can be completed by adding picking teeth 24 to the existing conveyor belt structure, which is convenient for processing and manufacturing and reduces manufacturing costs.

[0052] Specifically, the harvesting drive uses a hydraulic motor.

[0053] Specifically, the two ends of the harvesting drive shaft 21 are mounted on the connecting frame 12 via self-aligning bearings 25.

[0054] Specifically, multiple mounting plates are fixedly installed on the picking belt 23. The extension direction of the mounting plates is parallel to the axis of the picking drive shaft 21. Multiple picking teeth 24 plates are fixedly installed on the mounting plates, and multiple picking teeth 24 are fixedly installed on each picking tooth 24 plate.

[0055] Specifically, the connection between the mounting plate and the picking tooth 24 plate can be any existing detachable connection method. For example, the mounting plate is provided with multiple first connection holes, and the picking tooth 24 plate is provided with multiple second connection holes. Each first connection hole corresponds to one second connection hole, and the picking tooth 24 plate is fixed to the mounting plate by bolts and nuts.

[0056] Specifically, the picking belt 23 rotates from bottom to top relative to the harvested plants.

[0057] Specifically, the outer side of the picking teeth 24 is coated with rubber to reduce damage to the harvested plants and harvested materials when the picking teeth 24 brushes the harvested plants. The rubber coating also increases the surface friction coefficient during picking, thereby improving the picking efficiency and picking speed.

[0058] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 3 and Figure 5 As shown, both ends of the picking driven shaft 22 are connected to the connecting frame 12 via a tensioning mechanism 30. The output end of each tensioning mechanism 30 is connected to the corresponding end of the picking driven shaft 22, and the output end of each tensioning mechanism 30 can drive the end of the picking driven shaft 22 to move away from the picking drive shaft 21. The tensioning mechanism 30 can adjust the tension of the picking belt 23, thereby adjusting the brushing effect of the picking teeth 24 on the harvested plants.

[0059] Specifically, the tensioning mechanism 30 can be any existing structure capable of adjusting tension. Here, one such structure is described. The tensioning mechanism 30 includes a tensioning frame 31, an adjusting screw 32, an adjusting nut, and a slider 33. The tensioning frame 31 is fixed on the connecting frame 12 and has a sliding groove. The slider 33 is slidably disposed in the sliding groove and can move closer to or away from the harvesting drive shaft 21. The ends of the harvesting driven shaft 22 are rotatably connected to the corresponding sliders 33. The tensioning frame 31 has a guide hole, and the adjusting screw 32 passes through the guide hole. One end of the adjusting screw 32 is connected to the slider 33, and an adjusting nut is provided on each of the adjusting screws 32 located on both sides of the guide hole. The extension and retraction of the adjusting screw 32 in the guide hole can drive the slider 33 to move closer to or away from the harvesting drive shaft 21.

[0060] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-3 As shown, the machine frame 10 is also equipped with two transmission devices 40, each corresponding to a toothed belt comb device 20. Each transmission device 40 has a total transmission surface, with a portion of the total transmission surface located below the corresponding toothed belt comb device 20. The output end of the total transmission surface is connected to a collection box 50. The transmission devices are used to collect the harvested material from the plants and store it in their respective collection boxes 50, thus simultaneously performing both harvesting and collection functions, effectively improving the efficiency of large-scale harvesting and reducing labor costs.

[0061] Specifically, the transmission device 40 can be a single component or it can be composed of the first conveyor belt mechanism 41 and the second conveyor belt mechanism 42 below. The choice can be made based on factors such as actual manufacturing, assembly, harvesting effect and manufacturing cost.

[0062] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the conveying device includes a first conveyor belt mechanism 41 and a second conveyor belt mechanism 42. The first conveyor belt mechanism 41 is mounted on the frame 10 below the toothed brush device 20 on the same side. The second conveyor belt mechanism 42 is positioned between the first conveyor belt mechanism 41 and the corresponding collection box 50. The collection box 50 is vertically higher than the first conveyor belt mechanism 41. The first conveyor belt mechanism 41 has a first conveying surface, and the second conveyor belt mechanism 42 has a second conveying surface. The output end of the first conveying surface is connected to the input end of the second conveying surface, and the output end of the second conveying surface is connected and communicates with the collection box 50. By positioning the collection box 50 higher than the first conveyor belt mechanism 41, the storage capacity of the collection box 50 is increased vertically while minimizing the space occupied by its length in the first direction. This results in a shorter overall length of the device, improving maneuverability. Furthermore, the first conveyor belt mechanism 41 and the second conveyor belt mechanism 42 can collect the harvested materials into the collection box 50, resulting in a simple, stable, and reliable structure.

[0063] Specifically, the operating power of the first conveyor belt mechanism 41 and the second conveyor belt mechanism 42 can be provided by hydraulic motors.

[0064] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 3-5 As shown, two flower-catching scale plate assemblies 60 are rotatably arranged within the harvesting gap 11. The two flower-catching scale plate assemblies 60 are arranged opposite each other, and the gap between the two flower-catching scale plate assemblies 60 is used to clamp and fix the lower end of the harvested plant. Elastic elements are provided on the flower-catching scale plate assemblies 60, which can keep one side of the flower-catching scale plate assemblies 60 close to the other flower-catching scale plate assemblies 60. The two flower-catching scale plate assemblies 60 have conformal self-adaptive capabilities, that is, they can adjust the position of the harvested plant within the harvesting gap 11 through the elastic force of the elastic elements, adaptively adjusting for row deviations, thereby ensuring that the toothed comb brush devices 20 on both sides can evenly and effectively harvest the harvested plant within the harvesting gap 11. Furthermore, the two flower-catching scale plate assemblies 60 can seal the lower end of the harvested plant, ensuring that the harvested material does not fall into the field from the gap after falling off, thus improving collection efficiency.

[0065] Specifically, the flower scale plate assembly 60 consists of multiple plates, each plate being provided with tension by an elastic element, which can be a tension spring structure. Each plate can automatically reset under the tension of the elastic element after the harvested plant passes through, thereby keeping the harvesting gap 11 isolated from the ground.

[0066] Specifically, the two flower-grafting plate groups 60 can ensure that the harvested plants pass smoothly during the harvesting process while keeping the lower end of the harvested plants closed, thus collecting as much of the harvested material as possible.

[0067] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 5 As shown, in the vertical direction, the side of the flower-collecting scale assembly 60 closest to another flower-collecting scale assembly 60 is higher than the side of that flower-collecting scale assembly 60 furthest from another flower-collecting scale assembly 60, and the side of that flower-collecting scale assembly 60 furthest from another flower-collecting scale assembly 60 is not lower than the first conveying surface. The flower-collecting scale assembly 60 is configured with one side higher than the other, so that the harvested material can fall onto the flower-collecting scale assembly 60 and automatically roll down to the corresponding position by its tilt and its own weight, avoiding accumulation at the position where the harvested plant is held, thus improving the collection efficiency.

[0068] Specifically, the inclination angle of the 60-section flower scale plate assembly is 15°.

[0069] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, along the first direction, a branch gathering device 70 is also provided on the front side of the machine frame 10. The branch gathering device 70 has a gathering gap, the end of which is connected to and communicates with the input end of the harvesting gap 11, and the distance of the front end of the gathering gap along the second direction is greater than the distance of the harvesting gap 11 along the second direction. The branch gathering device 70 can gather the harvested plants, thereby facilitating the accurate introduction of the harvested plants into the harvesting gap 11 for subsequent harvesting work.

[0070] Specifically, the branch gathering device 70 can be as follows: Figure 2 The plate structure shown can also be a branch-gathering structure of other existing structural types.

[0071] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the walking system includes a power system 14 and a walking mechanism. The power system 14 is fixedly mounted on the frame 10 above the collection box 50, and the walking mechanism is located at the lower end of the frame 10. The power system 14 is used to drive the walking mechanism, and the walking mechanism can drive the frame 10 to move. By using the power system 14 mounted on the frame 10 to provide driving force, and the walking mechanism to achieve the self-propelled function of the equipment, the system has a high degree of integration, does not require traction equipment, and is more flexible and reliable.

[0072] Specifically, the power system 14 can be an engine or a combination of battery and motor, which can be selected according to actual needs.

[0073] Specifically, the walking mechanism includes four walking wheels 13, and the power system 14 can drive the four walking wheels 13 to rotate.

[0074] Specifically, a lifting device can be installed between the walking mechanism and the machine frame 10 to adjust the height of the machine frame 10 off the ground. The lifting device can be hydraulic.

[0075] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the toothed belt comb harvester 100 also includes a driver's cab 15, which is located on the machine frame 10 above the harvesting mechanism, and along the first direction, the driver's cab 15 is located in front of the power system 14. Positioning the driver's cab 15 above and in front of the machine frame 10 serves two purposes: firstly, it helps to balance the center of gravity of the equipment, ensuring its stability; secondly, the driver's cab 15's front position allows the operator to more clearly and intuitively see the plants to be harvested, facilitating alignment with the harvesting gap 11 and achieving highly efficient and precise harvesting.

[0076] Specifically, the cab 15 is equipped with control buttons or levers for controlling the power system 14, the walking mechanism, the lifting device, the conveying device, and the picking mechanism.

[0077] Specifically, a guardrail 16 is also provided around the cab 15 and the power system 14. The guardrail 16 is used to fix the machine frame 10.

[0078] Specifically, the machine frame 10 is also equipped with an escalator 17 to facilitate the driver's access to and from the cab 15.

[0079] Specifically, taking honeysuckle harvesting as an example: During honeysuckle harvesting, the traveling mechanism adjusts the height of the equipment chassis off the ground via a lifting device. The driver, inside the cab 15, precisely aligns the equipment with the honeysuckle plant. Once the device is running smoothly, the operation begins. As the machine advances, the honeysuckle branches are gathered by the branch gathering device 70 and enter the harvesting area. The toothed brush devices 20, located on both sides of the honeysuckle plant within the harvesting gap 11, brush the branches on the honeysuckle plant to pick the honeysuckle buds. The brushed-off honeysuckle flowers fall onto the flower-collecting scale plate group 60. Since the flower-collecting scale plate group 60 is inclined and positioned on one side of the first conveyor belt mechanism 41, the buds falling onto the flower-collecting scale plate group 60 slide into the first conveyor belt mechanism 41, then through the second conveyor belt mechanism 42, and finally fall into the corresponding collection box 50. Harvesting continues as the machine travels until the honeysuckle harvesting operation is completed.

[0080] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
