Description

Technical Field

[0001] This invention relates to the field of weeding equipment technology, specifically to a rapid weeding device for planting Chinese medicinal herbs. Background Technology

[0002] In the cultivation of Chinese medicinal herbs, weeds compete with the herbs for nutrients, water, and sunlight in the soil, severely affecting their growth and development, and reducing their yield and quality. Therefore, weeding is a crucial aspect of Chinese medicinal herb cultivation management. Currently, weeding methods in the field of Chinese medicinal herb cultivation mainly include manual weeding, chemical weeding, and mechanical weeding. Manual weeding is inefficient and labor-intensive, making it difficult to meet the needs of large-scale cultivation; while chemical weeding is more efficient, chemical agents tend to remain in the herbs, affecting their quality and damaging the soil's ecological environment, which is inconsistent with the development trend of green Chinese medicinal herb cultivation.

[0003] While existing mechanical weeding equipment has improved weeding efficiency to some extent, it still has many shortcomings: First, it has poor adaptability. The planting spacing of different types of Chinese medicinal herbs varies, and the planting spacing requirements of the same Chinese medicinal herb also differ at different growth stages. However, the walking and support structures of existing equipment are mostly fixed, which cannot flexibly adapt to different planting spacings, resulting in a limited operating range. Second, weed treatment is incomplete and the resource utilization rate is low. Most equipment can only cut or pull out weeds and cannot carry out subsequent processing of weeds. The pulled weeds are easy to grow again if they are piled up at will, and they are not converted into nutrients that are beneficial to the growth of Chinese medicinal herbs. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a rapid weeding device for medicinal herb cultivation. By employing a synchronously adjustable walking wheel and support frame structure, the spacing between the walking wheel and support frame can be flexibly adjusted according to the planting spacing requirements of different medicinal herbs and the spacing needs of the same herb at different growth stages. This allows the device to stably adapt to various medicinal herb cultivation scenarios. This structure breaks through the limitation of fixed spacing in traditional weeding equipment, eliminating the need for separate dedicated equipment for different planting spacings, effectively expanding the device's operating range, and reducing the equipment investment costs for large-scale medicinal herb cultivation.

This structure breaks through the limitations of traditional weeding equipment with fixed spacing, eliminating the need for separate dedicated equipment for different planting spacings, effectively expanding the equipment's operating range, and reducing the equipment investment costs for large-scale Chinese medicinal herb planting.

[0016] This integrated system combines weed removal, primary crushing, pesticide spraying, secondary crushing, and soil mixing. First, the weed-removing structure completely removes weeds from the soil. Then, the two-stage crushing structure progressively refines the weeds, while the pesticide spraying component ensures thorough mixing of the fungicide and the chopped weeds. Finally, the mixing structure integrates the treated chopped weeds with the soil. This integrated system not only avoids the problem of weed residue and proliferation but also promotes the rapid conversion of weeds into organic fertilizer, achieving resource recycling of weeds.

They are only for the convenience of describing this invention and 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 this invention.

[0022] Example 1 Please see Figures 1 to 7 As shown, a rapid weeding device for planting Chinese medicinal herbs includes a device frame 1. Two control handles are fixedly provided on one side of the device frame 1, and two crawling wheels 6 are rotatably provided on the other side. An adjustment unit 2 is provided on the side of the device frame 1 near the control handles, and support frames 3 are provided on both sides of the bottom of the adjustment unit 2. A drive unit 5 is provided on the side of the device frame 1 near the crawling wheels 6, and a weeding unit 7 is also provided in the middle of the device frame 1.

[0023] It should be noted that the drive unit 5 controls the two crawling wheels 6 to rotate, and the two crawling wheels 6 drive the weeding equipment to move quickly in the planting area. In conjunction with the adjustment unit 2, the support frame 3 is controlled to adjust the spacing, so that the weeding equipment can be used to quickly weed Chinese medicinal materials with different planting spacing.

[0024] like Figure 2 As shown, specifically, in order to adapt the weeding equipment to the weeding treatment of Chinese medicinal herbs with different planting spacings, the spacing between the two support frames 3 is flexibly adjusted by the adjustment unit 2, and the spacing between the two crawling wheels 6 is also adjusted, so that the weeding equipment can adapt to the weeding treatment of Chinese medicinal herbs with different planting spacings. The adjustment unit 2 includes an upper fixed frame 8, a mounting frame 9, and a lower fixed frame 10. The top and bottom of the equipment frame 1 are respectively fixed with the upper fixed frame 8 and the mounting frame 9. The bottom of the mounting frame 9 is fixed with a connecting frame 11, and the bottom of the connecting frame 11 is fixed with the lower fixed frame 10. The two sides inside the mounting frame 9 are fixed with adjustment servo cylinders 14, and the drive ends of the two adjustment servo cylinders 14 are fixed with adjustment frames 15. The upper telescopic blocks 12 and the lower telescopic blocks 13 are respectively fixed above and below the opposite side of the two adjustment frames 15. One side of the two upper telescopic blocks 12 is slidably connected to the two sides inside the upper fixed frame 8, and one side of the two lower telescopic blocks 13 is slidably connected to the two sides inside the lower fixed frame 10.

[0025] Furthermore, each of the two adjustment frames 15 is fixedly provided with a support frame 3 at its bottom, and each of the two support frames 3 is rotatably provided with several movable wheels 4 at its bottom.

[0026] It should be noted that when adjusting the distance between the two support frames 3, the two adjustment servo cylinders 14 inside the mounting frame 9 control the two adjustment frames 15 to move to both sides. The two adjustment frames 15 slide out of the upper fixed frame 8 and the lower fixed frame 10 through the extension and retraction of the upper extension block 12 and the lower extension block 13, respectively. The upper extension block 12 and the lower extension block 13 provide sliding support for the two adjustment frames 15, ensuring the stability of the two adjustment frames 15 after adjustment.

[0027] like Figure 3 and Figure 4As shown, specifically, after adjusting the spacing between the two adjustment frames 15, in order to achieve rapid weeding of medicinal herbs, the drive unit 5 controls the rotation of two crawler wheels 6, and simultaneously adjusts the spacing between the two crawler wheels 6 and the two adjustment frames 15. The drive unit 5 includes a drive box 16 and a servo reduction drive assembly 17 located inside the drive box 16. The drive box 16 is fixedly installed on one side of the top of the equipment frame 1, and the servo reduction drive assembly 17 is fixedly installed inside the drive box 16. The servo reduction drive assembly 17 is composed of a servo motor and a servo motor reducer. The output end of the servo reduction drive assembly 17 is fixedly equipped with a drive shaft 18. A transmission box 19 is fixedly installed on both the front and rear sides, and both ends of the drive shaft 18 pass through the drive box 16 and extend into the interior of the two transmission boxes 19; both sides of the interior of the two transmission boxes 19 are rotatably equipped with transmission gears 21, and the tooth surfaces of the two transmission gears 21 are connected by a synchronous belt 22; both ends of the drive shaft 18 are fixedly connected to the interior of the transmission gears 21 at the top of the two transmission boxes 19 respectively; a limiting frame 23 is fixedly installed at the bottom of one side of the equipment frame 1, and a transmission shaft 20 is rotatably installed inside the limiting frame 23, and both ends of the transmission shaft 20 are fixedly connected to the interior of the transmission gears 21 at the bottom of the two transmission boxes 19 respectively, and both ends of the transmission shaft 20 pass through the interior of the two transmission boxes 19 respectively.

[0028] Furthermore, both sides of the inside of the drive shaft 20 are slidably provided with limiting slide rods 24, and one end of each limiting slide rod 24 is fixedly connected to the inside of the two crawler wheels 6 respectively; the surface of the drive shaft 20 is provided with several limiting through holes 26, and one side of each of the surfaces of the two limiting slide rods 24 is provided with a limiting connection hole 25; the inside of each of the two limiting connection holes 25 is threaded with a limiting pin, and the limiting pin passes through the inside of the limiting through hole 26 on the surface of the drive shaft 20, thereby realizing the sliding limitation of the limiting slide rod 24 inside the drive shaft 20, so that the limiting slide rod 24 rotates synchronously with the rotation of the drive shaft 20; wherein, one side of the limiting frame 23 is provided with a rectangular through groove, and when the limiting through hole 26 on the surface of the drive shaft 20 is rotated to one side of the rectangular through groove, one end of the limiting pin can be flexibly threaded through the inside of the limiting through hole 26 and the limiting connection hole 25, and the surface of the limiting pin is covered with an anti-slip pad.

[0029] It should be noted that when the rapid weeding equipment is driven to move, the two ends of the drive shaft 18 synchronously control the upper transmission gears 21 inside the two transmission boxes 19 to rotate, and the synchronous belt 22 controls the lower transmission gears 21 inside the two transmission boxes 19 to rotate. The two lower transmission gears 21 drive the transmission shaft 20 to rotate, which in turn drives the two limiting slide rods 24 inside the transmission shaft 20 to rotate. One end of the two limiting slide rods 24 drives the two crawling wheels 6 to rotate synchronously. When adjusting the distance between the two crawling wheels 6, the limiting connection between the limiting connecting hole 25 and the limiting through hole 26 at one end of the two limiting slide rods 24 is changed, allowing the two limiting slide rods 24 to extend from inside the transmission shaft 20, thereby adjusting the distance between the two crawling wheels 6 to match the planting spacing of Chinese medicinal herbs. This allows the rapid weeding equipment to move quickly above the planting area of ​​Chinese medicinal herbs, and the two crawling wheels 6 and the two support frames 3 move in the planting furrows of Chinese medicinal herbs.

[0030] Example 2 like Figures 5 to 7 As shown, specifically, this embodiment describes the structure of the weeding unit 7 in the above embodiment, which, together with two adjustable-spacing crawling wheels 6 and two support frames 3, performs rapid weeding operations for medicinal herb cultivation. The weeding unit 7 includes a weeding control frame 27 and a weeding fixing frame 33. The bottom of the equipment frame 1 is fixed with the weeding control frame 27 by bolts. The bottom of the weeding control frame 27 is provided with a control groove 29, and a control screw 30 is rotatably installed inside the control groove 29. A servo control motor 28, which cooperates with one end of the control screw 30, is fixed on one side of the top of the weeding control frame 27. The output shaft of the servo control motor 28 and one end of the control screw 30 are connected by gear transmission or chain transmission. A control slider 31 is slidably installed inside the control groove 29, and the inside of the control slider 31 is threadedly connected to the surface of the control screw 30. A lifting servo cylinder 32 is fixed at the bottom of the control slider 31, and the driving end of the lifting servo cylinder 32 is fixed with the weeding fixing frame 33.

[0031] Furthermore, a connecting control frame 34 is fixedly installed on the lower sides of both sides inside the weeding fixing frame 33, and a weeding tooth frame 35 is rotatably installed at the bottom of each of the two connecting control frames 34. One end of each of the two weeding tooth frames 35 is driven to rotate by a micro servo motor built into one side of the connecting control frame 34. A shredder 36 is fixedly installed inside the weeding fixing frame 33. The shredder 36 has a shredding chamber 45 inside, and two shredding rollers 37 are rotatably installed inside the shredding chamber 45. A servo control motor 39 is fixedly installed on one side inside the weeding fixing frame 33. Two shredding gears 38 are rotatably installed on one side of the inner wall of the shredding chamber 45, and one end of each of the two shredding gears 38 is fixedly connected to one end of each of the two shredding rollers 37. The teeth of the two shredding gears 38 The teeth mesh and drive each other. One end of the output shaft of the servo control motor 39 is fixed with a drive gear that meshes with the teeth of one of the crushing gears 38. The output shaft of the servo control motor 39, in conjunction with the drive gear, controls the rotation of one of the crushing gears 38. The meshing transmission between the two crushing gears 38 causes the two crushing rollers 37 to rotate in opposite directions. After the weeds are inserted by the two weeding tooth frames 35, the drive end of the lifting servo cylinder 32 controls the weeding fixing frame 33 to move upward, pulling the weeds out of the soil. Then, the weeds are pushed into the crushing chamber 45. The two crushing rollers 37 crush the weeds from bottom to top. The crushed weeds enter the upper part of the crushing chamber 45.

[0032] Furthermore, guide frames 40 are fixedly installed on both sides inside the weeding fixing frame 33, and a pump 41 is fixedly installed on one side of each of the two guide frames 40. A pesticide tank 42 is also fixedly installed on the top of the two guide frames 40, and an atomizing nozzle is provided at the bottom of each of the two pesticide tanks 42. One end of the atomizing nozzle extends into the interior of the guide frame 40. One side of the interior of the guide frame 40 is connected to the interior of the crushing chamber 45, and the bottom of the guide frame 40 extends to the bottom of the crushing frame 36. Two crushing rollers 43 are also rotatably installed at the bottom inside the guide frame 40, and a servo control motor 44 for driving the two crushing rollers 43 to rotate relative to each other is provided on the front of each of the two guide frames 40.

[0033] It should be noted that after the weeds are crushed by the two crushing rollers 37, the pump 41 draws the crushed weeds into the guide frame 40. At the same time, the atomizing nozzle at the bottom of the agent tank 42 sprays the compound microbial agent inside the agent tank 42 into the crushed weeds. Then, the two crushing rollers 43 at the bottom of the guide frame 40 crush the weeds a second time. After the second crushing, the weeds fall onto the soil in the planting area. The weeding tooth frame 35 mixes the crushed weeds with the planting soil, converting the weeds into organic fertilizer for the planting of Chinese medicinal herbs.

[0034] Example 3 like Figures 1 to 7 As shown, specifically, this embodiment also discloses a working method for a rapid weeding device for planting Chinese medicinal herbs, as follows: Step 1: Activate the two adjustment servo cylinders 14 inside the mounting frame 9 in the adjustment unit 2. The drive end pushes the adjustment frame 15 to slide along the upper fixed frame 8 and the lower fixed frame 10 until the distance between the two support frames 3 is adapted to the width of the planting furrow for Chinese medicinal herbs. After adjustment, keep the adjustment servo cylinders 14 locked. Rotate the transmission shaft 20 so that the limiting through hole 26 on the surface of the transmission shaft 20 is aligned with the rectangular through groove on one side of the limiting frame 23. Unscrew the limiting pin and pull the two crawler wheels 6 to drive the limiting slide rod 24 to slide inside the transmission shaft 20 until the distance between the two crawler wheels 6 matches the distance between the support frames 3 and is adapted to the width of the furrow. After adjustment, thread the limiting pin through the corresponding limiting through hole 26 and the limiting connection hole 25 of the limiting slide rod 24 to achieve synchronous rotation and limiting of the limiting slide rod 24 and the transmission shaft 20.

[0035] Step 2: Open the servo reduction drive assembly 17 inside the drive box 16. Its output end drives the drive shaft 18 to rotate. The two ends of the drive shaft 18 drive the transmission gears 21 on the upper part of the two transmission boxes 19 to rotate. Through the synchronous belt 22, the transmission gears 21 on the lower part of the two transmission boxes 19 are driven to rotate, which in turn drives the transmission shaft 20 to rotate. The transmission shaft 20 drives the two crawling wheels 6 to rotate synchronously through the limit slide rod 24, driving the entire equipment to move along the planting furrow of Chinese medicinal herbs. Start the servo control motor 28 on the top of the weeding control frame 27. Through gear / chain transmission, drive the control screw 30 in the control slide 29 to rotate. The control slider 31 slides along the control screw 30 to the weeding area between the rows of Chinese medicinal herbs. Start the lifting servo electric cylinder 32. The drive end pushes the weeding fixing frame 33 down, so that the weeding tooth frame 35 is close to the soil surface, and the weeding operation height is calibrated.

[0036] Step 3: Start the micro servo motor on one side of the control frame 34 to drive the two weeding tooth frames 35 to rotate, so that the tooth tips insert into the root area of ​​the weeds and hold them in place; control the retraction of the drive end of the lifting servo cylinder 32 to move the weeding fixing frame 33 upward, completely pulling the weeds out of the soil and pushing them into the crushing chamber 45 of the crushing frame 36; start the second servo control motor 39 on one side of the weeding fixing frame 33, whose output shaft drives one of the crushing gears 38 to rotate through the drive gear, and the two crushing gears 38 mesh and drive the two crushing rollers. The first 37 rotates in the opposite direction in the crushing chamber 45 to crush the pulled weeds from bottom to top. The pump 41 on one side of the guide frame 40 is started to pump the crushed weeds from the crushing chamber 45 into the guide frame 40. At the same time, the atomizing nozzle at the bottom of the agent box 42 is turned on to spray the compound microbial agent in the box onto the crushed weeds. The servo control motor 44 on the front of the guide frame 40 is started to drive the two crushing rollers 43 to rotate relative to each other to crush the weeds after mixing the agent, so as to ensure that the particle size of the weeds meets the requirements of decomposition.

[0037] Step 4: After secondary crushing, the weeds fall onto the soil surface of the planting area through the bottom of the guide frame 40. The micro servo motor at the control frame 34 drives the weeding tooth frame 35 to rotate again, using the tooth ends to mix the surface soil and crushed grass, so that the crushed grass with the fungicide is embedded in the soil layer, preparing for subsequent decomposition into organic fertilizer. The equipment continues to move along the furrow under the drive of the crawler wheel 6, repeating the weeding-crushing-returning process of steps 3 to 4. During the operation, if the distribution of Chinese medicinal plants changes, the position of the control slider 31 is finely adjusted by the servo control motor 28 to ensure that the weeding tooth frame 35 and the crushing mechanism avoid the plants and prevent damage to the seedlings.

[0038] Step 5: After completing the weeding in the designated area, turn off the servo reduction drive assembly 17, each servo control motor, the material pump 41, and the pesticide spraying system in sequence; start the lifting servo cylinder 32 to raise the weeding fixing frame 33 to the highest position; adjust the servo cylinder 14 to retract the two support frames 3 to the initial distance; check and clean the crushing chamber 45, the material guide frame 40, and any remaining debris on the nozzle to complete the operation.
