Description
Technical Field
[0001] This utility model relates to the field of Chinese medicinal herb cultivation technology, specifically a multifunctional Chinese medicinal herb weeding machine. Background Technology
[0002] In the large-scale cultivation of Chinese medicinal herbs, weed control is a crucial step in ensuring the quality and yield of these herbs. Many Chinese medicinal herbs (such as Atractylodes macrocephala, Salvia miltiorrhiza, and Lycium barbarum) are shallow-rooted crops with fragile stems and leaves, making traditional weeding methods significantly limited: manual weeding is inefficient and unsuitable for large-scale cultivation; chemical weeding easily leads to pesticide residues, violating Good Agricultural Practices (GAP) standards for Chinese medicinal herbs, and may also damage the soil microecology.
[0003] Existing mechanical weeding equipment generally suffers from poor adaptability and insufficient adjustment precision. Most weeders on the market today are designed for field crops, which has certain shortcomings: First, the cutting height adjustment is crude, often using a single bolt or simple lever structure, with a small adjustment range, making it unsuitable for medicinal herbs at different growth stages (such as seedlings that require a gap of more than 5cm in plant height), easily causing damage to the stems and leaves of medicinal herbs; Second, it lacks flexibility, as the cutting components are mostly designed as a single piece, making it impossible to adjust individually for areas with uneven row spacing or clustered weeds, requiring frequent stops to adjust equipment parameters, thus reducing work efficiency. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a multifunctional Chinese herbal medicine weeder that solves the issues of coarse cutting height adjustment, small adjustment range, easy damage to the stems and leaves of medicinal herbs, lack of flexibility, and the inability to individually adjust the cutting components for areas with uneven row spacing or clustered weeds. This new model uses three independently adjustable telescopic rods to adapt to the weeding needs of different heights among medicinal herbs. Each set of telescopic rods can be individually controlled via the control panel to extend and retract, driving the second motor and cutting blades for a second step of fine-tuning.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional Chinese herbal medicine weeding machine, comprising a frame assembly, a drive assembly, and a weeding assembly. The frame assembly includes a side plate, the drive assembly includes a first motor and a U-shaped plate, and the weeding assembly includes a connecting column and a linkage plate. One end of the side plate is fixedly connected to a frame box by bolts. Positioning plates are symmetrically welded to the inner wall of the frame box. Linkage grooves are evenly spaced on the inner side of the inner wall of the positioning plate away from the frame box. A slide rail connected to the linkage grooves is provided on the inner side of the positioning plate. A double-ended screw is supported by a bearing seat on the inner side of the frame box. An adjusting sleeve is threaded to the outer wall of the double-ended screw. A positioning clamp is welded to the bottom of the adjusting sleeve. A diagonal rod is hinged to the inner side of the positioning clamp by a pin. A telescopic rod is bolted to the bottom of the linkage plate. A second motor is connected to the output end of the telescopic rod through a flange. A cutting blade is connected to the output end of the second motor through a key.
[0006] The beneficial effects of this utility model are as follows: After the first step of height adjustment of the cutting blade is completed, the extension and retraction of each set of telescopic rods can be controlled individually through the operation panel, which drives the second motor and the cutting blade to perform the second step of fine adjustment. After the adjustment is completed, the second motor is started, and its output shaft drives the cutting blade to rotate at high speed to achieve weeding. The three sets of independently adjustable telescopic rods are used to adapt to the weeding needs of the height difference between medicinal plants.
[0007] To lock the casters before starting the equipment for weed removal in the planting area: As a further improvement to the above technical solution: there are two side panels that are symmetrically welded to both sides of the top of the frame box. One end of the frame box is fixedly connected to a handrail by bolts, and the bottom of the side panels is connected to a universal wheel with braking function by axle.
[0008] The beneficial effects of this improvement are as follows: When using the equipment, first check whether the universal wheel brake device has been reset, hold the handle and push the device to the designated position in the Chinese herbal medicine planting area, lock the universal wheel and start the equipment to remove weeds in the planting area.
[0009] The groove is designed for sliding of the column via a slide rail, thereby limiting the movement trajectory of the U-shaped plate: As a further improvement to the above technical solution: the bottom of the positioning plate is welded and fixed to the bottom surface of the frame box, and three linkage grooves are opened at the close end of the two positioning plates. The width of the linkage groove is adapted to the diameter of the sliding crossbar to form a sliding fit structure. The slide rail is a T-shaped groove structure, which forms a guide sliding fit with the sliding column.
[0010] The beneficial effects of this improvement are: the groove for sliding the crossbar via the linkage groove, and the groove for sliding the column via the slide rail, thereby limiting the movement trajectory of the U-shaped plate.
[0011] To enable the first motor to output torque and drive the double-headed screw to rotate: As a further improvement to the above technical solution: the first motor is fixed to one side of the side plate by spring shock absorber bracket bolts, and the first motor is electrically connected to the operation panel on the handrail by wires.
[0012] The beneficial effects of this improvement are as follows: when adjusting the height of the cutting blade in the first step, the first motor is started through the operation panel, and the output torque of the first motor drives the double-headed screw to rotate.
[0013] To ensure that when the double-ended screw rotates clockwise, it drives the two adjusting sleeves to move away from each other axially: As a further improvement to the above technical solution: one end of the double-ended screw is connected to the output end of the first motor through an elastic coupling, and the end of the double-ended screw away from the first motor is rotatably connected to the inner wall of the frame box through a deep groove ball bearing. The outer wall of the double-ended screw is symmetrically machined with threads of opposite directions, and forms a helical transmission pair with the internal thread of the adjusting sleeve.
[0014] The beneficial effects of this improvement are as follows: after the first motor is started, when the double-headed screw rotates clockwise, it drives the two adjusting sleeves to move away from each other along the axial direction, and when it rotates counterclockwise, it drives the two adjusting sleeves to move closer to each other.
[0015] In order for the diagonal rod to rotate around the pivot and push the U-shaped plate to move downwards in the vertical direction: As a further improvement to the above technical solution: the positioning clamps are provided in two sets, and the two sets of positioning clamps are symmetrically welded to the bottom of the adjusting sleeve. Each pair of positioning clamps is set as a group, and the positioning clamps in the same group are hinged by a diagonal rod. The two ends of the diagonal rod are connected to the positioning clamps by pins to form a rotating pair.
[0016] The beneficial effects of this improvement are as follows: when the double-headed screw drives the two adjusting sleeves to move in opposite directions, the inclined rod rotates around the pin and pushes the U-shaped plate to move downward in the vertical direction; conversely, it pulls the U-shaped plate to move upward.
[0017] To ensure stability during the adjustment process, the two mechanisms must work together to limit the horizontal displacement of the U-shaped plate. As a further improvement to the above technical solution: a total of three connecting columns are provided. The connecting columns and the through holes opened at the bottom of the frame box form a sliding connection with clearance fit. The bottom of the connecting column passes through the frame box and is welded and fixed to the linkage plate. A sliding crossbar is welded to the outer wall of the U-shaped plate, and a sliding column is welded to the end of the sliding crossbar away from the U-shaped plate.
[0018] The beneficial effects of this improvement are as follows: when the U-shaped plate moves, the connecting column synchronously drives the linkage plate to adjust its height. During the movement of the U-shaped plate, the sliding crossbar slides along the linkage groove, and the sliding column slides along the slide rail. The two work together to limit the horizontal displacement of the U-shaped plate and ensure the stability of the adjustment process.
[0019] To accommodate weeding needs arising from differences in height between medicinal herb plants, three sets of independently adjustable telescopic rods are used: As a further improvement to the above technical solution: the telescopic rod is an electric push rod and is electrically connected to the operation panel, and the output end of the telescopic rod is bolted to the second motor through an L-shaped mounting base.
[0020] The beneficial effects of this improvement are as follows: After the first step of height adjustment of the cutting blade is completed, the extension and retraction of each set of telescopic rods can be controlled individually through the operation panel, which drives the second motor and the cutting blade to perform the second step of fine adjustment. After the adjustment is completed, the second motor is started, and its output shaft drives the cutting blade to rotate at high speed to achieve weeding. The three sets of independently adjustable telescopic rods are used to adapt to the weeding needs of the height difference between medicinal plants.
[0021] In summary, the beneficial effects of this solution are as follows: the sliding column slides along the slide rail, and the two work together to limit the horizontal displacement of the U-shaped plate, ensuring the stability of the adjustment process. After the adjustment is completed, the second motor is started, and its output shaft drives the cutting blade to rotate at high speed to remove weeds. Three sets of independently adjustable telescopic rods are used to adapt to the weeding needs of different heights between medicinal plants.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0030] like Figure 1-5 As shown, a multifunctional Chinese herbal medicine weeding machine includes a frame assembly 1, a drive assembly 2, and a weeding assembly 3. The frame assembly 1 includes a side plate 11. The drive assembly 2 includes a first motor 21 and a U-shaped plate 26. The weeding assembly 3 includes a connecting column 31 and a linkage plate 32. One end of the side plate 11 is fixedly connected to a frame box 13 by bolts. Positioning plates 14 are symmetrically welded to the inner wall of the frame box 13. Linkage grooves 16 are evenly spaced on the inner side of the inner wall of the positioning plate 14 away from the frame box 13. A slide rail 15 is provided that communicates with the linkage groove 16. A double-ended screw 22 is provided on the inner side of the frame box 13 through a bearing seat. An adjusting sleeve 23 is threadedly connected to the outer wall of the double-ended screw 22. A positioning clamp 24 is welded to the bottom of the adjusting sleeve 23. A diagonal rod 25 is hinged to the inner side of the positioning clamp 24 through a pin. A telescopic rod 33 is bolted to the bottom of the linkage plate 32. A second motor 34 is connected to the output end of the telescopic rod 33 through a flange. A cutting blade 35 is connected to the output end of the second motor 34 through a key.
[0031] There are two side panels 11, which are symmetrically welded to the two sides of the top of the frame box 13. One end of the frame box 13 is fixedly connected to the handrail 12 by bolts. The bottom of the side panels 11 is connected to the universal wheels with braking function through the wheel axle. When using, first check whether the universal wheel braking device has been reset, hold the handrail 12 and push the device to the designated position in the Chinese herbal medicine planting area. After locking the universal wheels, start the equipment to remove weeds in the planting area.
[0032] The bottom of the positioning plate 14 is welded and fixed to the bottom surface of the frame box 13. Three linkage grooves 16 are provided at the close ends of the two positioning plates 14. The groove width of the linkage groove 16 is adapted to the diameter of the sliding crossbar 36 to form a sliding fit structure. The slide rail 15 is a T-shaped groove structure, which forms a guide sliding fit with the sliding column 37. The linkage groove 16 is used for the sliding crossbar 36 to slide, and the slide rail 15 is used for the sliding column 37 to slide, thereby limiting the movement trajectory of the U-shaped plate 26.
[0033] The first motor 21 is fixed to one side of the side plate 11 by spring shock absorber bracket bolts. The first motor 21 is electrically connected to the operation panel on the handrail 12 by wires. When adjusting the height of the cutting blade 35 for the first time, the first motor 21 is started through the operation panel. The first motor 21 outputs torque to drive the double-headed screw 22 to rotate.
[0034] One end of the double-ended screw 22 is connected to the output end of the first motor 21 via a flexible coupling. The end of the double-ended screw 22 away from the first motor 21 is rotatably connected to the inner wall of the frame box 13 via a deep groove ball bearing. The outer wall of the double-ended screw 22 is symmetrically machined with threads of opposite directions, and forms a helical transmission pair with the internal thread of the adjusting sleeve 23. After the first motor 21 is started, when the double-ended screw 22 rotates clockwise, it drives the two adjusting sleeves 23 to move away from each other axially, and when it rotates counterclockwise, it drives the two adjusting sleeves 23 to move closer to each other.
[0035] Two sets of positioning clamps 24 are provided, and the two sets of positioning clamps 24 are symmetrically welded to the bottom of the adjusting sleeve 23. Each pair of positioning clamps 24 is set as a group. The positioning clamps 24 in the same group are hinged by a diagonal rod 25. The two ends of the diagonal rod 25 form a rotating pair with the positioning clamps 24 through pins. When the double-headed screw 22 drives the two adjusting sleeves 23 to move in opposite directions, the diagonal rod 25 rotates around the pin and pushes the U-shaped plate 26 to move downward in the vertical direction. Conversely, it pulls the U-shaped plate 26 to move upward.
[0036] Three connecting columns 31 are provided. The connecting columns 31 and the through holes opened at the bottom of the frame box 13 form a sliding connection with clearance fit. The bottom of the connecting column 31 passes through the frame box 13 and is welded and fixed to the linkage plate 32. A sliding crossbar 36 is welded to the outer wall of the U-shaped plate 26. A sliding column 37 is welded to the end of the sliding crossbar 36 away from the U-shaped plate 26. When the U-shaped plate 26 moves, the linkage plate 32 is adjusted in height synchronously through the connecting columns 31. During the movement of the U-shaped plate 26, the sliding crossbar 36 slides along the linkage groove 16 and the sliding column 37 slides along the slide rail 15. The two work together to limit the horizontal displacement of the U-shaped plate 26 and ensure the stability of the adjustment process.
[0037] The telescopic rod 33 is an electric push rod and is electrically connected to the control panel. The output end of the telescopic rod 33 is bolted to the second motor 34 through an L-shaped mounting base. After the first step of height adjustment of the cutting blade 35 is completed, the telescopic rods 33 are individually controlled to extend and retract through the control panel, driving the second motor 34 and the cutting blade 35 to perform the second step of fine adjustment. After the adjustment is completed, the second motor 34 is started, and its output shaft drives the cutting blade 35 to rotate at high speed to achieve weeding. The three sets of independently adjustable telescopic rods 33 are used to adapt to the weeding needs of the height difference between medicinal plants.
[0038] The working principle of this utility model is as follows: When in use, first check if the universal wheel brake device has been reset. Hold the handle 12 and push the device to the designated position in the medicinal herb planting area. After locking the universal wheel, start the equipment to remove weeds from the planting area. When adjusting the height of the cutting blade 35 for the first step, start the first motor 21 via the control panel. The first motor 21 outputs torque to drive the double-headed screw 22 to rotate. When the double-headed screw 22 rotates clockwise, it drives the two adjusting sleeves 23 to move away from each other axially. When it rotates counterclockwise, it drives the two adjusting sleeves 23 to move closer together. When the double-headed screw 22 drives the two adjusting sleeves 23 to move away from each other, the inclined rod 25 rotates around the pin and pushes the U-shaped plate 26 downward in the vertical direction. Conversely, it pulls the U-shaped plate 26 upward. When the U-shaped plate 26 moves, it is synchronously driven by the connecting column 31. The linkage plate 32 is height-adjusted. During the movement of the U-shaped plate 26, the sliding crossbar 36 slides along the linkage groove 16, and the sliding column 37 slides along the slide rail 15. The two work together to limit the horizontal displacement of the U-shaped plate 26 and ensure the stability of the adjustment process. The linkage groove 16 is the groove for the sliding crossbar 36 to slide, and the slide rail 15 is the groove for the sliding column 37 to slide, which in turn limits the movement trajectory of the U-shaped plate 26. After the first step of height adjustment of the cutting blade 35 is completed, the extension and retraction of each set of telescopic rods 33 are controlled individually through the operation panel, which drives the second motor 34 and the cutting blade 35 to perform the second step of fine adjustment. After the adjustment is completed, the second motor 34 is started, and its output shaft drives the cutting blade 35 to rotate at high speed to achieve weeding. The three sets of independently adjustable telescopic rods 33 are used to adapt to the weeding needs of the height difference between medicinal plants.
