Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and specifically to an intelligent weeding device for traditional Chinese medicine fields with self-adjustment function. Background Art

[0002] A weeding device for traditional Chinese medicine fields is an agricultural mechanical equipment specifically used to remove weeds in traditional Chinese medicine planting fields. It usually consists of a power system, a transmission device, a weeding working component, etc. The power system generally uses an engine or an electric motor to provide the power source for the device. The transmission device transmits the power to the weeding working component, enabling it to perform actions such as rotation, cutting, or excavation. The weeding working component varies according to different weeding principles and methods. Common ones include the rotary cutter type, which cuts weeds by means of a high-speed rotating cutter; and the excavation type, which can dig out weeds with roots to achieve the purpose of thorough weeding.

[0003] Chinese Patent CN216820723U discloses a special weeding robot for farmland, including a weeding machine. The weeding machine drives a cutter to rotate for cutting. The cutter is located inside a protective cover. The lower end of a lifting side frame is rotatably connected with a roller. The upper end of the lifting side frame is slidably inserted on a guiding column at the upper end of the weeding machine. The inner wall of the upper end of the protective cover is provided with a pair of semi-circular scrapers that are symmetric left and right. The lower end of the scraper is connected to the lower end of the lifting side frame through a pull rope. The beneficial effect is that by setting a roller frame that can be lifted and adjusted, the height of the roller can be adapted to different heights of the ground, and during the propulsion process, the device is kept stable, enabling the cutter to rotate parallel for cutting, thereby achieving effective weeding and cutting.

[0004] As shown in the above patent, common weeding devices for traditional Chinese medicine fields mostly adopt a rotary cutter operation mode to cut weeds by driving the cutter to rotate at a high speed. However, such devices have obvious drawbacks in practical applications. The planting plan of traditional Chinese medicine fields is diverse, and the planting density varies greatly in different areas, resulting in significant changes in the row spacing. The cutter size of existing weeding devices is fixed, so the cutting coverage range cannot flexibly adapt to the changing row spacing, greatly limiting the operation efficiency of the device.

[0005] In addition, to prevent the cutter from damaging traditional Chinese medicine plants, it is difficult for the device to effectively cut the weeds between plants in the same row during operation. This limitation not only reduces the comprehensiveness of weeding, resulting in incomplete cleaning of weeds in the field, but also affects the optimization of the traditional Chinese medicine planting environment, reduces the weeding quality, and is difficult to meet the agronomic requirements of modern large-scale and refined planting of traditional Chinese medicine.

[0006] Therefore, it is necessary to provide an intelligent weeding device for traditional Chinese medicine fields with self-adjustment function to solve the above technical problems. Summary of the Invention

[0007] The object of the present invention is to provide an intelligent Chinese medicine field weeding device with a self - adjusting function. By setting a cutting rope with an adjustable extension length, the cutting path of the cutting rope can flexibly cover the gap between two rows of Chinese medicine plants, overcoming the problem that the cutting knife size of the existing weeding device is fixed and the cutting coverage range cannot flexibly adapt to the row spacing, and greatly improving the operation efficiency of the device.

The output end of the second motor is fixedly connected to the top end of the driving screw. The driving screw penetrates the second sliding seat and is threadedly connected to the second sliding seat. The second sliding seat is fixedly connected to the middle of the lifting rod.

[0013] A further setting of the present invention is that a transmission assembly is arranged on one side of the transverse guide rail, and the transmission assembly is in transmission connection with the double-headed screw to drive the double-headed screw to rotate.

[0014] A further setting of the present invention is that the transmission assembly includes a vertical plate, a rotating shaft rotatably installed at the top of the vertical plate, a third gear fixedly sleeved on the rotating shaft, and a rack meshing with the third gear. The rack is fixedly connected with the lifting rod through a connecting rod. The bottom end of the vertical plate is fixedly connected with the transverse guide rail. Transmission wheels are fixedly sleeved at the ends of the rotating shaft and the double-headed screw, and the two transmission wheels are in transmission connection through a transmission belt.

At the same time, the visual system and control system set on the device can comprehensively and real-time collect the position information of the traditional Chinese medicine plants and the cutting rope in the operation area. When it is recognized that the cutting rope is about to contact the traditional Chinese medicine plants, the distance between the two rotating disks can be reduced and the cutting rope can be retracted into the rotating cylinder by a part to avoid the cutting rope cutting the traditional Chinese medicine plants. While ensuring that the plants are not damaged, compared with the traditional device, it can also more effectively cut the weeds between the plants in the same row, improve the comprehensiveness of weeding, optimize the traditional Chinese medicine planting environment, improve the weeding quality, and meet the agronomic requirements of modern large-scale and refined planting of traditional Chinese medicine.

Detailed implementation manners

[0028] The following will further illustrate the present invention in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figures 1 to 6, in the embodiment of the present invention, an intelligent Chinese medicine field weeding device with a self-adjusting function includes two support plates 4, a lateral driving component for driving the two support plates 4 to move horizontally in opposite directions, a rotating cylinder 5 rotatably connected to the support plates 4, a power component for driving the rotating cylinder 5 to rotate, and a plurality of cutting ropes 8. The rotating cylinder 5 penetrates through the support plates 4, and a rotating disk 6 is fixedly installed at the bottom end of the rotating cylinder 5. A sliding disk 7 is slidably installed up and down in the rotating cylinder 5. The top end of the cutting rope 8 is fixedly connected to the sliding disk 7, and the bottom end of the cutting rope 8 extends out from the outer peripheral wall of the rotating disk 6. Each sliding disk 7 is fixedly connected to four cutting ropes 8. The cutting ropes 8 are made of multiple strands of nylon ropes woven together. The top end of the sliding disk 7 is rotatably connected to an adjusting rod 19. Above the adjusting rod 19, there is an adjusting component for driving the adjusting rod 19 to move up and down. When the adjusting component drives the adjusting rod 19 to move up and down, it drives the sliding disk 7 to move up and down, thereby enabling the cutting ropes 8 to extend or contract into the rotating cylinder 5 to adjust the extending length of the cutting ropes 8. During specific use, the weeding device is installed on an intelligent driving vehicle body (not shown in the figure). The intelligent driving vehicle body drives the weeding device to travel smoothly along the gap between two rows of Chinese medicine plants through the navigation and driving system, and drives the two support plates 4 to move horizontally in opposite directions through the lateral driving component and drives the adjusting rod 19 to move up and down through the adjusting component to adjust the extending length of the cutting ropes 8, so that the cutting path of the cutting ropes 8 just covers the gap between two rows of Chinese medicine plants. The device is provided with a vision system and a control system (not shown in the figure). This system consists of multiple high-resolution cameras 33 and image sensors, and can collect the position information of Chinese medicine plants and cutting ropes 8 in the operation area omnidirectionally and in real time. The image data collected by the vision system will be transmitted to the control system in real time. The control system uses advanced image recognition algorithms and intelligent decision-making models to analyze and process the data. The vision system and the control system are prior arts and will not be described in detail here. When the control system recognizes that the cutting ropes 8 are about to approach or contact the Chinese medicine plants, it will immediately issue an instruction. When it recognizes that the cutting ropes 8 are about to cut the Chinese medicine plants, it will reduce the distance between the two rotating disks 6 and make the cutting ropes 8 contract a part into the rotating cylinder 5 to avoid the cutting ropes 8 cutting the Chinese medicine plants.

[0030] The present invention can automatically and flexibly adjust the distance between two support plates 4 by providing a lateral drive assembly capable of driving the two support plates 4 to move horizontally in opposite directions. Furthermore, it can adapt to the row spacing variations in different regions of the traditional Chinese medicine field due to differences in planting density. The adjustment assembly drives the lifting of the adjusting rod 19 to drive the lifting of the sliding disk 7, enabling the cutting rope 8 to extend or retract into the rotating cylinder 5, thereby realizing the adjustment of the extended length of the cutting rope 8. This allows the cutting path of the cutting rope 8 to flexibly cover the gap between two rows of traditional Chinese medicine plants, overcoming the problems of the fixed cutting knife size and the inability of the cutting coverage range to flexibly adapt to the row spacing in existing weeding devices, greatly improving the operating efficiency of the equipment. At the same time, the visual system and control system provided on the device can comprehensively and real-time collect the position information of the traditional Chinese medicine plants and the cutting rope 8 in the operation area. When it is recognized that the cutting rope 8 is about to contact the traditional Chinese medicine plants, the distance between the two rotating disks 6 can be reduced and the cutting rope 8 can be retracted partially into the rotating cylinder 5 to avoid the cutting rope 8 cutting the traditional Chinese medicine plants. Moreover, while ensuring no damage to the plants, compared with traditional devices, it can more effectively cut the weeds between the plants in the same row, improving the comprehensiveness of weeding, optimizing the traditional Chinese medicine planting environment, enhancing the weeding quality, and meeting the agronomic requirements of modern large-scale and refined traditional Chinese medicine planting.

[0031] In this embodiment, preferably, the lateral drive assembly includes a lateral guide rail 1, a double-headed screw 2 rotatably installed inside the lateral guide rail 1, and two first sliding seats 3 slidably arranged inside the lateral guide rail 1. The support plate 4 is fixedly connected to the first sliding seat 3. The double-headed screw 2 penetrates through the two first sliding seats 3, and the double-headed screw 2 is threadedly connected to the two first sliding seats 3. Two sections of reverse thread grooves are provided on the double-headed screw 2, and the two sections of reverse thread grooves are respectively in threaded cooperation with the two first sliding seats 3, such that when the double-headed screw 2 rotates, the two first sliding seats 3 move synchronously in opposite directions.

[0032] In this embodiment, preferably, the power assembly includes a mounting plate 9, a first motor 10 fixedly installed on the mounting plate 9, a first gear 11 fixedly connected to the output end of the first motor 10, and a second gear 12 fixedly sleeved on the rotating cylinder 5. The mounting plate 9 is fixedly connected to the support plate 4. The first gear 11 meshes with the second gear 12. When driving the rotation of the rotating cylinder 5, the first motor 10 is turned on, and the output end of the first motor 10 drives the first gear 11 to rotate, thereby driving the rotation of the rotating cylinder 5 through the second gear 12, so that the cutting rope 8 rotates to cut the weeds.

[0033] In this embodiment, preferably, the adjusting assembly includes a lifting rod 17 arranged horizontally, a longitudinal driving assembly for driving the lifting rod 17 to move up and down, and two sliders 18 slidably arranged on the lifting rod 17. The top end of the adjusting rod 19 is fixedly connected to the slider 18. The longitudinal driving assembly includes a longitudinal guide rail 13, a driving screw rod 14 rotatably installed inside the longitudinal guide rail 13, and a second sliding seat 15 slidably installed inside the longitudinal guide rail 13. The longitudinal guide rail 13 is fixedly installed at the middle of the top end of the transverse guide rail 1. The top end of the longitudinal guide rail 13 is fixedly installed with a second motor 16. The output end of the second motor 16 is fixedly connected to the top end of the driving screw rod 14. The driving screw rod 14 penetrates through the second sliding seat 15 and is threadedly connected to the second sliding seat 15. The second sliding seat 15 is fixedly connected to the middle of the lifting rod 17. When it is necessary to drive the adjusting rod 19 to move up and down to adjust the extending length of the cutting rope 8, control the rotation of the output end of the second motor 16, thereby driving the driving screw rod 14 to rotate. When the driving screw rod 14 rotates, it drives the second sliding seat 15 to rise or fall, and then drives the lifting rod 17 to move up and down. When the lifting rod 17 moves up and down, it drives the adjusting rod 19 to move up and down through the slider 18, thereby driving the sliding disc 7 to move up and down to adjust the extending length of the cutting rope 8. Through the arrangement of the lifting rod 17 and the slider 18, when the rotating cylinder 5 drives the adjusting rod 19 to move horizontally, it does not affect the lifting of the adjusting rod 19 by the lifting rod 17.

[0034] In this embodiment, preferably, a transmission assembly is provided on one side of the transverse guide rail 1. The transmission assembly is in transmission connection with the double-headed screw 2 to drive the double-headed screw 2 to rotate. The transmission assembly includes a vertical plate 23, a rotating shaft 21 rotatably installed at the top of the vertical plate 23, a third gear 24 fixedly sleeved on the rotating shaft 21, and a rack 25 meshing with the third gear 24. The rack 25 is fixedly connected to the lifting rod 17 through a connecting rod 26. The bottom end of the vertical plate 23 is fixedly connected to the transverse guide rail 1. Transmission wheels 22 are fixedly sleeved at the ends of the rotating shaft 21 and the double-headed screw 2, and the two transmission wheels 22 are in transmission connection through a transmission belt 20. When the longitudinal driving assembly drives the lifting rod 17 to descend, the lifting rod 17 drives the rack 25 to move downward through the connecting rod 26. When the rack 25 moves downward, it drives the rotating shaft 21 to rotate through the third gear 24. When the rotating shaft 21 rotates, it drives the double-headed screw 2 to rotate through the transmission wheels 22 and the transmission belt 20, so that the two first sliding seats 3 move away from each other, and further the two rotating discs 6 move away from each other. When the lifting rod 17 descends, it can drive the sliding disc 7 to descend, so that the length of the cutting rope 8 extending out of the rotating disc 6 increases. The moving distance of the rotating disc 6 is the same as the extending length of the cutting rope 8, so that the cutting paths of the two cutting ropes 8 can cover the space between the two rotating discs 6. The setting of the transmission assembly enables the lifting and lowering of the lifting rod 17 and the rotation of the double-headed screw 2 to be synchronized, and further enables the telescopic movement of the cutting rope 8 and the movement of the rotating disc 6 to be synchronized, ensuring that the cutting path of the cutting rope 8 can cover the space between the two rotating discs 6, with good synchronism, effectively avoiding the close impact between the cutting ropes 8 or the existence of a cutting blind area due to the long distance between them.

[0035] In this embodiment, preferably, a plurality of cameras 33 are installed at the bottom end of the transverse guide rail 1. The cameras 33 are part of the vision system. The cameras 33 adopt high-resolution imaging technology and have a wide-angle shooting function, and can comprehensively and clearly collect the image information of the traditional Chinese medicine plants and weeds in the traditional Chinese medicine field. A control system is also provided on the device. This system integrates advanced image recognition algorithms. After the cameras 33 collect the image information, it will be transmitted to the control system in real time. The control system uses the algorithm to analyze the image, accurately identify the positions, shapes and distribution of the traditional Chinese medicine plants and weeds. During the operation process, based on the above recognition results, the control system will issue an instruction to the first motor 10, and the first motor 10 controls the extending length of the cutting rope 8 and the spacing between the rotating discs 6 through the transmission mechanism. When encountering an area with a wide column spacing, the cutting rope 8 extends a longer distance to increase the cutting width and improve the weeding efficiency. When approaching the traditional Chinese medicine plants, the extending length of the cutting rope 8 is shortened to effectively avoid the cutting rope 8 accidentally hurting the traditional Chinese medicine plants. With the coordinated cooperation among the cameras 33, the control system and the first motor 10, this device realizes the precise regulation of the cutting width, while ensuring the weeding effect, minimizing the damage to the traditional Chinese medicine plants to the greatest extent.

[0036] In this embodiment, preferably, a connecting seat 27 is provided at the rear side of the transverse guide rail 1. The connecting seat 27 is fixedly connected to the intelligent driving vehicle body. An oil cylinder 28 is fixedly installed on the connecting seat 27. The output end of the oil cylinder 28 is fixedly connected to the transverse guide rail 1. The weeding device involved in the present invention is mounted on the intelligent driving vehicle body. The device is driven by the intelligent driving vehicle body to flexibly travel in the traditional Chinese medicine field. The intelligent driving vehicle body integrates advanced multi-sensor fusion technology and intelligent decision-making system to ensure the stability and accuracy of the driving process. The driving path planning of the intelligent driving vehicle body relies on the accurate analysis of the farmland structure. Before the operation, the operator can use technologies such as unmanned aerial vehicle mapping and satellite positioning to obtain detailed information such as the topography and plant distribution of the traditional Chinese medicine field, and construct a high-precision farmland digital model. At the same time, the vehicle body is equipped with a high-precision positioning system, such as the Global Navigation Satellite System (GNSS), Inertial Navigation System (INS), and landmark positioning module based on visual recognition, which can obtain the position information of the vehicle body in the farmland in real time. During the operation, the intelligent driving vehicle body transmits the obtained farmland structure data and real-time positioning information to the in-vehicle central processor. The central processor uses the path planning algorithm to analyze and calculate these data. The algorithm takes avoiding traditional Chinese medicine plants, improving the weeding coverage rate, and reducing the redundancy of the driving path as the optimization goal, and plans the optimal driving route. According to the planned route, the control system sends instructions to the execution components such as the driving motor and steering mechanism of the vehicle body to realize the vehicle body traveling along the specified route in the traditional Chinese medicine field. This process not only ensures that the weeding device can comprehensively and efficiently cover the traditional Chinese medicine field, but also effectively avoids unnecessary damage to the traditional Chinese medicine plants, greatly improving the operation quality and efficiency. The transverse guide rail 1 can be driven to lift by the oil cylinder 28, so as to adjust the height of the cutting rope 8, so that the cutting rope 8 performs cutting work at a height 10-20 mm above the ground.

[0037] Please refer to Figure 7 and Figure 8, in the embodiment of the present invention, a liquid storage bottle 29 is fixedly installed at the top end of the slider 18. The adjusting rod 19 is hollow inside, and the top end of the adjusting rod 19 is communicated with the liquid storage bottle 29. Herbicides are placed in the liquid storage bottle 29, and the herbicides can flow into the adjusting rod 19. A plurality of rolling balls 30 are embedded at the bottom of the adjusting rod 19. There is a gap between the rolling balls 30 and the adjusting rod 19, so that when the rolling balls 30 rotate, the herbicides in the adjusting rod 19 can flow downward through the gap. An osmotic plate 31 is fixedly installed inside the sliding disk 7. A plurality of micropores are formed on the osmotic plate 31, so that the herbicides can penetrate downward. The rolling balls 30 are in contact with the top wall of the osmotic plate 31. A sponge seat 32 is fixedly installed at the bottom end of the osmotic plate 31. The top end of the cutting rope 8 penetrates through the sponge seat 32 and is fixedly connected to the bottom wall of the osmotic plate 31. The sponge seat 32 has good water absorption and water retention properties, and can fully absorb and store the herbicides. One end of the cutting rope 8 is in close contact with the sponge seat 32. The herbicides will gradually penetrate from the sponge seat 32 to the cutting rope 8, and along the surface of the cutting rope 8, gradually flow downward under the action of gravity and capillary action; when the rotating cylinder 5 rotates, the rotating cylinder 5 drives the sliding disk 7 to rotate synchronously, while the adjusting rod 19 remains fixed. When the sliding disk 7 rotates, it drives the osmotic plate 31 to rotate, so that the osmotic plate 31 drives the rolling balls 30 to rotate. When the rolling balls 30 rotate, the herbicides in the adjusting rod 19 flow along the surface of the rolling balls 30 to the osmotic plate 31, and penetrate into the sponge seat 32 through the micropores on the osmotic plate 31, and then gradually penetrate to the cutting rope 8, and gradually flow downward along the surface of the cutting rope 8 under the action of gravity and capillary action, so that the cutting rope 8 is attached with the herbicides. In this way, when the cutting rope 8 cuts the weeds, the herbicides attached to the cutting rope 8 can be accurately attached to the cut-off openings of the weeds. The cut-off openings are the exposed surfaces of the weed tissues, which greatly facilitates the absorption of the herbicides. The herbicides will quickly penetrate into the weeds, interfere with the physiological metabolism process of the weeds, block the transmission of their nutrients and water, and cause the weeds to die in a short time. This way of applying pesticides realizes the precise targeted application of pesticides to the weeds, avoids the large-area spraying of herbicides, and effectively prevents the herbicides from contacting the Chinese herbal medicines. It not only significantly reduces the usage amount of the herbicides, reduces the production cost and environmental risks, but also can ensure the weeding effect, and provides a strong guarantee for the green and healthy growth of the Chinese herbal medicines.

[0038] The above is only the preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structures, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
