Description

Technical Field

[0001] This invention relates to weeding devices, specifically to a clamp-type combined mechanical and pesticide weeding device. Background Technology

[0002] Current agricultural weed control systems primarily rely on two technological approaches: mechanical weeding, which optimizes the structure and operating parameters of agricultural machinery to achieve the best balance between weeding efficiency and soil disturbance; and chemical weeding, which focuses on developing technologies to reduce pesticide use and establishing precision application models based on environmental toxicology. However, the effectiveness of mechanical weeding equipment is limited by insufficient accuracy in identifying weeds between crop plants. More challenging is the fact that residual weed roots easily re-germinate, forcing repeated operations and significantly increasing the risk of physical damage to seedlings. Simultaneously, the development of herbicide resistance has outpaced the development of new herbicides; barnyard grass populations in major agricultural areas of my country have developed significant resistance to multiple herbicides. Long-term overuse of herbicides has created a vicious cycle of "increased resistant weeds → spread of chemical pollution → ecosystem imbalance." Furthermore, excessive herbicide application severely pollutes farmland groundwater, directly jeopardizing drinking water safety. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems and provide a clamping-type mechanical and pesticide synergistic weeding device. This weeding device integrates a multidisciplinary perspective and synergistically integrates two types of weeding methods. First, it clamps and positions the weeds and performs mechanical pretreatment. Then, it is supplemented with a small amount of herbicide to achieve precise, efficient and low-environmental-risk weed control.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A clamp-type mechanical and chemical weeding device includes a mechanical weeding mechanism and a chemical weeding mechanism;

[0006] The mechanical weeding mechanism includes a fixed clamping plate, a movable clamping plate, and a swing drive mechanism. The swing drive mechanism is used to drive the movable clamping plate to swing closer to the fixed clamping plate to clamp the weeds.

[0007] The chemical weeding mechanism includes a medicine box and a delivery pipe. The fixed clamp is provided with a delivery hole, and the delivery pipe connects the medicine box and the delivery hole.

[0008] The working principle of the above-mentioned clamp-type combined mechanical and pesticide weeding device is as follows:

[0009] During operation, the device tilts vertically or at a certain angle depending on the working environment. As the machine moves forward, weeds enter the gap between the fixed and movable clamps. At this point, the swing drive mechanism drives the movable clamp to swing, bringing it closer to the fixed clamp for a non-fixed clamping of the weeds, ensuring that the weeds remain in contact with both rough surfaces simultaneously. As the machine continues to move forward, the weeds experience relative movement with the fixed and movable clamps, causing friction and partial tearing of the weed surface by the rough surfaces, creating wounds. Subsequently, a small amount of pesticide is sprayed through the application port onto the wounded surface of the weeds, killing them.

[0010] In a preferred embodiment of the present invention, the swing drive mechanism includes a swing drive motor and a swing transmission assembly, wherein the swing drive motor is fixedly mounted on a fixed clamping plate.

[0011] The swing transmission assembly includes a first swing rod, a second swing rod, and a third swing rod. One end of the first swing rod is fixedly connected to the output shaft of the swing drive motor. One end of the second swing rod is hinged to the other end of the first swing rod. The third swing rod has an arc-shaped structure. One end of the third swing rod is hinged to the other end of the second swing rod, and the other end of the third swing rod is fixedly connected to the movable clamping plate. The portion between the two ends of the third swing rod is hinged to a hinge seat via an intermediate connecting rod. The hinge seat is fixedly mounted on the fixed clamping plate.

[0012] With the above structure, driven by the swing drive motor, the first swing rod swings first, and then drives the second and third swing rods, so that the third swing rod rotates around the hinge seat, thereby enabling the movable clamping plate to move closer to or away from the fixed clamping plate.

[0013] In a preferred embodiment of the invention, both the fixed clamp and the movable clamp have a frosted surface. This significantly increases friction, making it easier to damage weeds.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The weeding device of the present invention first adopts the operation mode of clamping and positioning and mechanically destroying the epidermal cells of weeds, and then precisely spraying herbicide: mechanical treatment can construct directional damage channels on the epidermis of weeds, destroy the continuous structure of the cuticle and expose the symptom channel, thereby significantly enhancing the penetration, conductivity and killing efficacy of the herbicide; only a small amount of herbicide is needed to achieve systemic killing of weeds, greatly improving the utilization efficiency of herbicide.

[0016] 2. Researchers' series of explorations have confirmed the feasibility of this model. Preliminary field practices have also yielded good results: the synergistic effect of applying pesticides after physical damage is significant, overcoming the shortcomings of insufficient mortality from mechanical weeding alone, and greatly reducing the amount of herbicide used, effectively mitigating the disturbance to the farmland ecosystem from both physical and chemical dimensions.

[0020] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] Combination Figures 1-3 The clamping-type combined mechanical and chemical weeding device of this embodiment includes a mechanical weeding mechanism and a chemical weeding mechanism; the mechanical weeding mechanism includes a fixed clamping plate 1, a movable clamping plate 2, and a swing driving mechanism, the swing driving mechanism being used to drive the movable clamping plate 2 to swing closer to the fixed clamping plate 1 to clamp the weeds; the chemical weeding mechanism includes a medicine box and a medicine delivery pipe, the fixed clamping plate 1 is provided with a medicine application hole 101, and the medicine delivery pipe is connected between the medicine box and the medicine application hole 101.

[0022] Combination Figures 1-3 The swing drive mechanism includes a swing drive motor 3 and a swing transmission assembly. The swing drive motor 3 is fixedly mounted on the fixed clamping plate 1. The swing transmission assembly includes a first swing rod 4, a second swing rod 5, and a third swing rod 6. One end of the first swing rod 4 is fixedly connected to the output shaft of the swing drive motor 3. One end of the second swing rod 5 is hinged to the other end of the first swing rod 4. The third swing rod 6 has an arc-shaped structure. One end of the third swing rod 6 is hinged to the other end of the second swing rod 5. The other end of the third swing rod 6 is fixedly connected to the movable clamping plate 2. The portion between the two ends of the third swing rod 6 is hinged to the hinge seat 8 through an intermediate connecting rod 7. The hinge seat 8 is fixedly mounted on the fixed clamping plate 1.

[0023] With the above structure, driven by the swing drive motor 3, the first swing rod 4 swings first, and then drives the second swing rod 5 and the third swing rod 6, so that the third swing rod 6 rotates around the hinge seat, thereby enabling the movable clamping plate 2 to move closer to or further away from the fixed clamping plate 1.

[0024] Furthermore, both the fixed clamp 1 and the movable clamp 2 have a frosted surface. This greatly increases friction, making it easier to damage weeds.

[0025] Combination Figures 1-3 The working principle of the above-mentioned clamp-type mechanical pesticide combined weeding device is as follows:

[0026] During operation, the device tilts vertically or at a certain angle depending on the working environment. As the machine moves, weeds enter the gap between the fixed clamp 1 and the movable clamp 2. At this time, the swing drive mechanism drives the movable clamp 2 to swing, bringing it closer to the fixed clamp 1 to perform a non-fixed clamping of the weeds, ensuring that the weeds remain in contact with the rough surfaces of both clamps simultaneously. As the machine continues to move forward, the weeds generate relative movement with the fixed clamp 1 and the movable clamp 2. The rough surfaces rub against the weed surface, causing partial tearing and creating wounds on the weed surface. Subsequently, a small amount of pesticide solution is sprayed through the application hole 101 onto the wounded surface of the weeds, killing them.

[0027] The weeding device of the present invention first adopts a working mode of clamping and positioning and mechanically destroying the epidermal cells of weeds, and then precisely spraying herbicides: mechanical treatment can construct directional damage channels on the weed epidermis, destroy the continuous structure of the cuticle and expose the symptom channel, thereby significantly enhancing the penetration, conductivity and killing efficacy of the herbicide; only a small amount of herbicide is needed to achieve systemic killing of weeds, greatly improving the utilization efficiency of herbicide.

[0028] Researchers' series of explorations have confirmed the feasibility of this model. Preliminary field practices have also yielded good results: the synergistic effect of applying pesticides after physical damage is significant, overcoming the shortcomings of insufficient mortality from mechanical weeding alone, and greatly reducing the amount of herbicide used, effectively mitigating the disturbance to the farmland ecosystem from both physical and chemical dimensions.

[0029] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
