Description

Technical Field

[0001] This invention relates to the field of weeding devices, and more specifically, to a weeding device for herbaceous Chinese medicinal herbs under natural forest canopies that is easy to adjust. Background Technology

[0002] Planting herbal medicinal herbs under natural forest canopies is an ecological agricultural model that can meet the growth needs of some shade-loving medicinal herbs by utilizing the shade environment of the forest, while also protecting the forest ecology and improving the economic benefits of the land. However, natural forest canopies contain a variety of plants of different heights, including trees, small trees, shrubs, and herbs, and the density of trees is irregular. Therefore, before planting medicinal herbs, the forest canopy needs to be prepared by using weeding equipment.

[0003] Weed cutters are common weeding devices that automatically cut grass on the ground. A search revealed Chinese patent CN118901311A, which discloses a forestry weeding device, relating to the field of weeding machine technology. The device includes a weeding cart with four wheels at its four corners, a cutting disc at the front bottom, and two symmetrically arranged long shears at the center bottom. The shears adjust the width of each cut by extending and retracting. A root-digging and soil-loosening mechanism is located at the rear bottom of the cart, and a water tank is located at the center top, with spray pipes on both sides. This design adjusts the width of each cut by extending and retracting the long shears and loosening the soil at the rear bottom to thoroughly remove weeds. However, this design still has the following shortcomings in practical use:

[0004] When the above-mentioned solution is used, the staff pushes the device to move it in the forest. When the weeding device covers the plants, it can automatically cut off the plants. However, due to the limitation of the machine size, the working range of the weeding device is limited. The staff needs to keep pushing the device and moving it to the location of the plants in order to complete the weeding. This limits the work efficiency and increases the labor intensity and operation time.

[0005] Based on this, the present invention discloses an easily adjustable herbicide removal device for natural forest understory. Summary of the Invention

[0006] To address the problem of limited weeding range in existing weeding devices as mentioned in the background section, this invention provides an easily adjustable weeding device for natural forest understory herbs and medicinal plants. The device includes an outer frame, on which a swing assembly is mounted. The swing assembly includes a rotating shaft, with a swing plate fixed to the end of the rotating shaft furthest from the outer frame. A mounting bracket is fixed to the end of the swing plate, and a mowing device is mounted on the mounting bracket. A fixing rod is fixed to the end of the swing plate furthest from the mounting bracket, and a control lever is fixed to the swing plate.

[0007] The outer frame is equipped with a guide assembly, which provides guidance for the swing plate;

[0008] The external frame is equipped with a drive assembly for driving the swing plate to swing. The drive assembly includes a drive structure and a lifting structure. The lifting structure includes a fixed frame. The lifting plate is slidably disposed in the fixed frame, and the side of the lifting plate is in contact with the fixed frame. A push plate is fixed to the top of the lifting plate. The push plate is connected to the fixed frame by a spring. The lifting plate is made of magnetic material.

[0009] The outer frame is equipped with an adjustment component for adjusting the swing amplitude of the swing plate;

[0010] The mounting bracket is equipped with a control component for controlling the horizontal position of the fixed frame;

[0011] Since the existing weeding devices have a limited weeding range, this technical solution uses a swingable plate. The swing plate drives the mowing equipment to swing, which can significantly increase the weeding range. During weeding, the mowing equipment weeds in a fan-shaped area, which improves work efficiency, shortens the movement path of the device, and reduces the labor intensity of workers.

[0012] As a further improvement to this technical solution, the guide assembly includes a guide plate, which is connected to the outer frame through two connecting plates. The guide plate has an arc-shaped structure and a guide opening is provided on the guide plate. A vertical rod is slidably arranged in the guide opening and fixed to the bottom surface of the swing plate. Two limiting rings are fixedly sleeved on the vertical rod.

[0013] Based on this, in order to improve the stability of the swing plate, this solution designs a guide component to provide guidance for the swing plate;

[0014] As a further improvement to this technical solution, the drive structure includes a mounting frame, on which a reciprocating lead screw is rotatably mounted. A movable seat is threaded onto the reciprocating lead screw, and the bottom surface of the movable seat is in contact with the outer frame. A side plate is fixed to the side of the movable seat, and two opposing fixed seats are fixed on the side plate. A crossbar is fixed between the two fixed seats, and a slider is slidably mounted on the crossbar. The slider is fixedly connected to the fixed frame.

[0015] In another scheme, in order to drive the swing plate to swing, this scheme uses a reciprocating lead screw to drive the slider as a power source to realize the periodic swing of the swing plate in the forward and reverse directions.

[0016] As a further improvement to this technical solution, the adjustment assembly includes two bearing seats, both of which are fixed on the top surface of the outer frame and are positioned opposite each other. An adjustment screw is rotatably installed between the two bearing seats. The adjustment screw has two threads of the same length but opposite directions. A limit rod is fixed between the two bearing seats, and two adjustment seats are slidably sleeved on the limit rod. The two adjustment seats are threaded onto the two threads respectively. A first electromagnet is installed on one of the adjustment seats, and a second electromagnet is installed on the other adjustment seat.

[0017] In order to adjust the swing amplitude of the swing plate, this solution is designed with an adjustment component. By adjusting the positions of the first electromagnet and the second electromagnet, the swing amplitude of the swing plate can be controlled, so that the equipment can dynamically adjust the weeding range according to the slope of the forest and the distribution of plants.

[0018] As a further improvement to this technical solution, the first electromagnet and the second electromagnet are staggered.

[0019] As a further improvement to this technical solution, the control component includes two side rods, a first control plate and a second control plate. The two side plates are respectively fixed on both sides of the fixed frame. The first control plate and the second control plate are respectively located at both ends of the mounting frame. The first control plate and the second control plate are both fixedly connected to the mounting frame through connecting rods. The first control plate and the second control plate are both provided with inclined surfaces, and the inclination directions of the two inclined surfaces are opposite.

[0020] As a further improvement to this technical solution, the two side plates are respectively positioned opposite the first control plate and the second control plate.

[0021] As a further improvement to this technical solution, the two limiting rings are located on the upper and lower sides of the guide plate, respectively, and each limiting ring is in contact with the guide plate.

[0022] As a further improvement to this technical solution, a damping component is provided on the slider to provide damping for the slider. The damping component includes a through-hole, in which a damping block is slidably disposed and abuts against a crossbar. A movable rod is fixed on the damping block, and the end of the movable rod away from the damping block extends to the outside of the through-hole. A fixing frame is fixed on the side of the slider, and a hole is opened on the fixing frame. The movable rod passes through the hole and slides in the hole. The movable rod and the fixing frame are connected by a tension spring.

[0023] As a further improvement to this technical solution, two slots are provided on the push plate, and rolling columns are rotatably installed in both slots.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. This device, through the linkage design of the swing component and the drive component, enables the mowing equipment to swing in a fan-shaped trajectory, significantly increasing the mowing area within the same working stroke. Compared to traditional linear mowers, it has a wider coverage area, making it especially suitable for densely planted areas of natural forest understory herbs and medicinal plants, effectively reducing the number of manual back-and-forth operations and significantly improving overall efficiency.

[0026] 2. The adjustment component adopts a two-way threaded screw and electromagnet linkage design. The distance between the first and second electromagnets can be adjusted via a handwheel, thereby precisely controlling the amplitude of the swing plate. This design allows the equipment to dynamically adjust the weeding range according to the forest slope and plant distribution, avoiding damage to target herbs due to excessive swinging and preventing missed weeds. The addition of a damping component further ensures the stability of the slider position, prevents vibration deviation, and improves operational accuracy.

[0027] 3. The combination of mechanical damping components and guiding components achieves highly stable oscillation and positioning without the need for complex electronic control. Manual adjustment and mechanical transmission reduce reliance on external power or sensors. The simple and durable structure is suitable for the harsh environment of forest farms, characterized by dust and high loads, while also reducing maintenance costs and operational complexity.

[0038] 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.

[0039] Existing weeding devices have a small operating range, low operating efficiency, and require a high level of manual labor.

[0040] Therefore, this invention provides an easily adjustable weeding device for herbaceous medicinal plants under natural forest canopies, see [link to relevant documentation]. Figure 1As shown, it includes an outer frame 1, on which casters are installed for mobility. A handle is also fixed to the outer frame 1 for easy pushing by the operator. A swing assembly is installed on the outer frame 1, including a rotating shaft 20. A swing plate 21 is fixed to the end of the rotating shaft 20 away from the outer frame 1. A mounting bracket 22 is fixed to the end of the swing plate 21, and a mowing device 23 is mounted on the mounting bracket 22. A fixing rod 24 is fixed to the end of the swing plate 21 away from the mounting bracket 22, and a control lever 25 is fixed to the swing plate 21. The operator can manually control the swing of the mowing device 23 via the control lever 25 to fine-tune the working area of ​​the mowing device 23, such as... Figure 1 As shown, during lawn mowing, the swing plate 21 can swing around the rotating shaft 20, and the lawn mowing device 23 swings accordingly. When the lawn mowing device 23 swings, it can form a fan-shaped working area, such as... Figure 3 As shown, compared to traditional weeders, it significantly increases the working area while covering the same distance, thereby improving work efficiency;

[0041] See Figure 1 As shown, a guide assembly is provided on the outer frame 1. The guide assembly provides guidance for the swing plate 21. The guide assembly includes a guide plate 32, which is connected to the outer frame 1 through two connecting plates 31. The guide plate 32 has an arc-shaped structure and a guide opening 33. A vertical rod 34 is slidably arranged in the guide opening 33. The vertical rod 34 is fixed to the bottom surface of the swing plate 21. Two limiting rings 35 are fixedly sleeved on the vertical rod 34. The two limiting rings 35 are located on the upper and lower sides of the guide plate 32, respectively. Each limiting ring 35 is in contact with the guide plate 32. During the swing of the swing plate 21, the vertical rod 34 moves accordingly. During this process, the guide opening 33 provides guidance to ensure the stability of the swing plate 21 during the swing. In addition, the setting of the two limiting rings 35 makes the vertical rod 34 only able to move in the horizontal direction and not in the vertical direction.

[0042] See Figure 4As shown, a drive assembly is provided on the outer frame 1 to drive the swing plate 21 to swing. The drive assembly includes a drive structure and a lifting structure. The drive structure includes a mounting frame, on which a reciprocating screw 41 is rotatably mounted. The reciprocating screw 41 is driven by a motor. The motor is prior art and is not shown in the figure, so it will not be described in detail here. When the motor runs, the reciprocating screw 41 rotates. A movable seat 42 is threaded onto the reciprocating screw 41, and the bottom surface of the movable seat 42 is in contact with the outer frame 1. When the reciprocating screw 41 rotates, because the bottom surface of the movable seat 42 is in contact with the outer frame 1, therefore... The movable seat 42 cannot rotate with the reciprocating screw 41, but moves back and forth under the action of the rotation of the reciprocating screw 41. A side plate 43 is fixed on the side of the movable seat 42, and two fixed seats 44 are fixed on the side plate 43. A crossbar 45 is fixed between the two fixed seats 44. A slider 46 is slidably sleeved on the crossbar 45. It should be noted that in order to restrict the slider 46 to only move horizontally along the slide bar and not rotate, a spline can be set on the slide bar and a keyway can be set on the slider 46 to restrict the movement of the slider 46. This is the prior art and is not shown in the figure. It will not be described in detail here.

[0043] See Figure 7 As shown, the lifting structure includes a fixed frame 51, which is fixed to the side of the slider 46. A lifting plate 52 is slidably disposed in the fixed frame 51, and the side of the lifting plate 52 is in contact with the fixed frame 51. A push plate 54 is fixed to the top of the lifting plate 52. The push plate 54 is connected to the fixed frame 51 by a spring 53. The lifting plate 52 is made of magnetic material. In the initial state, the push plate 54 is located directly opposite the fixed rod 24. In this case, when the push plate 54 moves with the moving seat 42, it can contact the fixed rod 24 and push the fixed rod 24 to move. When the fixed rod 24 is pushed, the fixed rod 24 can drive the swing plate 21 to swing around the rotating shaft 20.

[0044] See Figure 4 As shown, an adjustment assembly is provided on the outer frame 1 to adjust the swing amplitude of the swing plate 21. The adjustment assembly includes two bearing seats 61, both of which are fixed to the top surface of the outer frame 1 and are positioned opposite each other. An adjustment screw 62 is rotatably mounted between the two bearing seats 61. The adjustment screw 62 has two threads of the same length but opposite directions. A limit rod 63 is fixed between the two bearing seats 61. Two adjustment seats 64 are slidably sleeved on the limit rod 63. The two adjustment seats 64 are threaded onto the two threads respectively. A first electromagnet 65 is mounted on one adjustment seat 64, and a second electromagnet 66 is mounted on the other adjustment seat 64. The first electromagnet 65 and the second electromagnet 66 are staggered, forming a... Figure 8 The state shown;

[0045] See Figure 8As shown, a control assembly is provided on the mounting bracket. The control assembly includes two side rods 41, a first control plate 72, and a second control plate 73. The two side plates 43 are respectively fixed on both sides of the fixed frame 51. The first control plate 72 and the second control plate 73 are respectively located at both ends of the mounting bracket. The first control plate 72 and the second control plate 73 are both fixedly connected to the mounting bracket through connecting rods 74. The first control plate 72 and the second control plate 73 are both provided with inclined surfaces, and the inclination directions of the two inclined surfaces are opposite. When the top rod is pressed against the inclined surface, the top rod will move along the inclined surface and drive the fixed frame 51 to move. When the fixed frame 51 moves, the slider 46 and the crossbar 45 provide limit for it.

[0046] When weeding, the worker starts the motor. The motor drives the reciprocating screw 41 to rotate, which in turn drives the moving seat 42 to move back and forth. Figure 8 As shown, the direction indicated by the black arrow is defined as the forward movement of the movable seat 42, and conversely, the reset process of the movable seat 42 is defined as the reverse movement of the movable seat 42. In the initial state, the movable seat 42 moves forward. During this process, the push plate 54 first passes the first electromagnet 65. However, since the push plate 54 and the first electromagnet 65 are misaligned, the lifting plate 52 will not move downward under the magnetic attraction of the first electromagnet 65. That is, at this time, the magnetic attraction of the first electromagnet 65 to the lifting plate 52 is insufficient to make the lifting plate 52 overcome the elastic force of the spring 53 and move downward. As the push plate 54 continues to move, the push plate 54 will collide with the fixed rod 2. The four phases come into contact and push the fixed rod 24 to move. When the fixed rod 24 is pushed, it can drive the swing plate 21 to rotate. Furthermore, when the lifting plate 52 moves directly above the second electromagnet 66, since the lifting plate 52 and the second electromagnet 66 are directly opposite each other and the distance between them is very small, the magnetic attraction of the second electromagnet 66 to the lifting plate 52 can make the lifting plate 52 overcome the elastic force of the spring 53 and move downward. When the lifting plate 52 moves downward, the push plate 54 moves downward accordingly. When the push plate 54 moves downward, it will separate from the fixed rod 24. When the two separate, the push plate 54 no longer applies a pushing force to the fixed rod 24, and the swing plate 21 also stops swinging.

[0047] See Figure 8As shown, when the fixed frame 51 moves to the end position of the mounting bracket, the side rod 71 corresponding to the second control plate 73 will contact the inclined surface of the second control plate 73 and move along the inclined surface of the second control plate 73. Guided by the inclined surface of the second control plate 73, the side rod 71 will drive the fixed frame 51 to move, causing the slider 46 to move along the crossbar 45. When the forward movement of the fixed frame 51 ends, the fixed frame 51 just slides to the other end of the slide bar. In this case, the lifting plate 52 is offset from the second electromagnet 66 and faces the first electromagnet 65. Based on the above principle, it can be understood that during the reverse movement of the fixed frame 51, the lifting plate 52 will first pass the second electromagnet. 66. However, since the two are in a mutually offset state, the lifting plate 52 will not move under the attraction of the second electromagnet 66. Then, the push plate 54 pushes the fixed rod 24, causing the fixed rod 24 to drive the swing plate 21 to rotate in the opposite direction until the lifting plate 52 moves directly above the first electromagnet 65. According to the above principle, the lifting plate 52 will move downward under the attraction of the first electromagnet 65, causing the push plate 54 and the fixed rod 24 to separate again. When the two separate, the swing plate 21 stops swinging. In summary, during the process of the push plate 54 following the moving seat 42 to move back and forth, the push plate 54 can drive the swing plate 21 to swing in the forward and reverse directions, thereby achieving the effect of expanding the working area of ​​the mowing equipment 23.

[0048] Furthermore, the present invention provides two slots on the side of the push plate 54, and two rolling columns 55 are provided in the two slots. When the push plate 54 moves, the rolling columns 55 will contact the fixed rod 24. When the push plate 54 moves down, the rolling columns 55 can roll under the action of friction, thereby reducing the friction between the push plate 54 and the fixed rod 24, which is conducive to the smooth descent of the push plate 54.

[0049] This solution also provides a function to adjust the swing amplitude of the swing plate 21 to cope with the complex terrain environment of the forest farm. Specifically, a handwheel is installed at one end of the adjusting screw 62, which can be used by the operator to control the rotation of the adjusting screw 62. Since the adjusting screw 62 has two threads of the same length but opposite directions, and the two adjusting seats 64 are threaded onto the two threads respectively, when the adjusting screw 62 rotates, the two adjusting seats 64 can move closer or further apart, thereby adjusting the position of the first electromagnet 65 and the second electromagnet 66. By adjusting the position of the first electromagnet 65 and the second electromagnet 66, the pushing... The downward movement of plate 54 controls the swing amplitude of swing plate 21 and mowing device 23. This design significantly improves the adaptability of the weeding device to complex forest terrain, enabling the device to adjust the working range according to different terrains and plant distribution. It avoids accidental damage to surrounding vegetation due to excessive swing amplitude, and prevents weeds from being missed due to insufficient amplitude. At the same time, the manual adjustment method is easy to operate and does not rely on complex external power or control systems. While ensuring functional reliability, it reduces manufacturing costs and maintenance difficulty, effectively balancing automation efficiency and the flexibility of manual intervention, making weeding operations more efficient and adaptable to diverse environmental needs.

[0050] See Figure 7 As shown, a damping assembly is provided on the slider 46 to provide damping for the slider 46. The damping assembly includes a through-hole 81, in which a damping block 82 is slidably disposed, and the damping block 82 abuts against the crossbar 45. A movable rod 83 is fixed on the damping block 82, and the end of the movable rod 83 away from the damping block 82 extends to the outside of the through-hole 81. A fixing bracket 84 is fixed on the side of the slider 46, and a hole is opened in the fixing bracket 84. The movable rod 83 passes through the hole and slides in the hole. The movable rod 83 and the fixing bracket 84 are connected by a tension spring 85. Under the action of the tension spring 85, the damping block 82... The damping block 82 always tends to press against the crossbar 45. This design creates a certain friction between the damping block 82 and the crossbar 45. This friction ensures that the slider 46 can only move when it is acted upon by the first control plate 72 and the second control plate 73. In other states, the position of the slider 46 will not easily change. The design of the damping component allows the slider 46 to maintain mechanical stability in complex working environments. This ensures the reliability of the position adjustment of the swing plate 21 and eliminates the need for an additional complex locking mechanism, simplifying the overall structure and effectively suppressing the positioning deviation caused by the free sliding of the slider 46.
