Description

Technical Field

[0001] This utility model belongs to the field of weeding technology, specifically relating to a highly efficient and environmentally friendly automatic weeding device. Background Technology

[0002] Current weeding methods primarily rely on manual weeding and the use of pesticides. Manual weeding typically requires farmers to operate directly in the field with hoes, which is not only time-consuming and labor-intensive, but also inefficient, easily leading to worker fatigue and increasing planting costs. Furthermore, manual weeding is often ineffective, failing to completely remove weeds, and is particularly difficult to implement on large areas of farmland. While pesticide weeding can solve these problems to some extent, it poses risks of environmental pollution and may affect the quality and safety of crops.

[0003] Therefore, there is an urgent need in the market for an economical, practical, easy-to-manufacture, safe and reliable automated weeding solution to reduce the intensity of manual labor, improve weeding efficiency, reduce farmers' planting costs, and at the same time avoid the negative impact of pesticides on the environment and crops. Utility Model Content

[0004] The present invention aims to provide a highly efficient and environmentally friendly automatic weeding device to solve the technical problems of existing weeding methods being time-consuming, labor-intensive, and polluting to the environment.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A highly efficient and environmentally friendly automatic weeding device includes a beam frame with a three-point suspension frame installed on the beam frame. Ground wheel frames are symmetrically installed on the left and right sides of the front of the beam frame, and ground wheels are installed on the ground wheel frames. Several weeding assemblies are arranged on the rear side of the beam frame, with all weeding assemblies arranged side by side at intervals.

[0007] Each weeding assembly includes a longitudinal beam, with a depth-limiting wheel installed at the front end of the longitudinal beam. Two crossbeams are fixed on the longitudinal beam, and mowing mechanisms are installed at both ends of the crossbeams. The mowing mechanism includes a spring steel bracket and a mowing shovel. The spring steel bracket is fixed on the crossbeam, and a ruler is fixed to the upper end of the mowing shovel. The ruler has graduation lines and is threaded through the spring steel bracket and fixed by bolts. The ruler has graduation lines.

[0008] Furthermore, the beam frame includes a front beam and a rear beam, with the ground wheel frame and three-point suspension frame mounted on the front beam and all weeding assemblies mounted on the rear beam.

[0009] Furthermore, the weeding assembly also includes a mounting bracket and a parallel four-bar linkage structure. The mounting bracket is installed on the rear beam body by two sets of U-bolts. The parallel four-bar linkage structure is connected to the mounting bracket and the longitudinal beam. A spring is also provided on the parallel four-bar linkage structure.

[0010] Furthermore, the grass-cutting shovel has an L-shaped bend structure or a dovetail structure, and the edges of the L-shaped bend structure and the dovetail structure are provided with blades.

[0011] Furthermore, the front beam and the rear beam are connected by several sets of connecting parts. The connecting parts are respectively connected to the front beam and the rear beam by hinge. With the setting of the connecting parts, the front beam and the rear beam can swing left and right relative to each other. A left and right adjustment cylinder is also installed between the front beam and the rear beam. The piston rod of the left and right adjustment cylinder is connected to the rear beam.

[0012] A seat bracket is fixed in the middle of the front beam. The seat bracket extends rearward and a seat is installed on the seat bracket. A steering pump is also installed on the front beam. The steering pump is connected to the steering wheel via a control lever. The steering pump is connected to the left and right adjustment cylinders via oil pipes. The steering pump can be controlled by operating the steering wheel.

[0013] Furthermore, the rear beam includes a central beam and two folding rods. The two folding rods are connected to both ends of the central beam by hinges. Two sets of folding hydraulic cylinders are also installed on the central beam, and the piston rods of the folding hydraulic cylinders are connected to the upper parts of the two folding rods respectively.

[0014] Furthermore, the aforementioned efficient and environmentally friendly automatic weeding device also includes a camera and a monitoring display screen. The camera is mounted on the longitudinal beam, and the monitoring display screen is connected to the camera via a wiring connection.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model adopts a modular weeding assembly combined with a parallel four-bar linkage contouring mechanism to ensure a weeding rate of over 95% at a standard depth of 3cm, while achieving a depth control accuracy of ±1mm through a ruler; the combination of an articulated beam frame and a hydraulic steering system solves the tracking problem of non-linear crop rows and controls the seedling damage rate; the innovative three-section folding rear beam design reduces the transport width and allows for quick conversion between working states; this utility model weeding device has three core advantages: terrain-adaptive, precise fine-tuning, and rapid folding. It is suitable for continuous operations on large farms and can also meet the refined needs of small plots. The entire process of mechanical weeding eliminates the use of pesticides, and the overall operation and maintenance cost is reduced by more than 25% compared with traditional solutions, making it an ideal equipment for modern green agriculture.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The present invention will be further described in detail below with reference to the embodiments.

[0024] like Figure 1-5 As shown, here is a specific embodiment 1 of the efficient and environmentally friendly automatic weeding device provided by this utility model:

[0025] A high-efficiency and environmentally friendly automatic weeding device includes a beam frame, which includes a front beam 2 and a rear beam 3. A three-point suspension frame 4 is installed on the front beam 2 for quick connection with an agricultural vehicle. Ground wheel frames 5 are symmetrically installed on the left and right sides of the front beam 2. Ground wheels 6 are installed on the ground wheel frames 5. The setting of the ground wheels 6 can ensure the stable movement of the device. Six weeding assemblies 7 are set on the rear beam 3. All weeding assemblies 7 are arranged side by side at intervals.

[0026] Each weeding assembly 7 includes a longitudinal beam 8, which is set horizontally in the front and rear direction. A depth-limiting wheel 9 is installed at the front end of the longitudinal beam 8. Two crossbeams 10 are fixed on the longitudinal beam 8. Both ends of the crossbeams 10 are equipped with a mowing mechanism. The mowing mechanism includes a spring steel bracket 12 and a mowing shovel 13. The spring steel bracket 12 is fixed on the crossbeam 10. A ruler 14 is fixed at the upper end of the mowing shovel 13. The ruler 14 is provided with scale lines. The ruler 14 passes through the spring steel bracket 12 and is fixed by bolts 16. The ruler 14 is provided with scale lines.

[0027] The weeding device described in this embodiment can be moved across the field by being towed by an agricultural vehicle. A hydraulic control system is installed between the agricultural vehicle and the beam frame. The hydraulic control system and the three-point suspension frame 4 are conventional technologies in this field, and the specific connection structure will not be described in detail. During weeding operations, the lifting and lowering operation of the beam frame is achieved through the hydraulic control system (compatible with the standard hydraulic interface of the agricultural vehicle). During the lowering process, the weeding shovel 13 is aligned with a position 2cm away from the seedling eye, and at this time, the weeding shovel 13 is inserted into the ground 3cm. Then, under the towing of the agricultural vehicle, the device can move in the field. During the movement, the weeding shovel 13 cuts the roots of the weeds in the soil, achieving the environmentally friendly effect of "root weeding".

[0028] In this embodiment, the depth-limiting wheel 9 and the ground wheel 6 work together to ensure the smooth movement of the device. The mowing shovel 13 is mounted on the spring steel bracket 12, allowing the mowing shovel 13 to be elastically adjusted according to the terrain. In addition, the mowing shovel 13 is connected to the spring steel bracket 12 through a ruler 14 with precision scale lines. The fixing position of the bolt 16 can be quickly adjusted according to the scale. By changing the position of the ruler 14 on the spring steel bracket 12, the soil penetration depth of the mowing shovel 13 can be precisely controlled (the standard setting is 3cm underground).

[0029] In this embodiment, the lawnmower 13 can be an L-shaped lever structure 18 (such as...). Figure 4 ), or a swallowtail structure 19 (such as Figure 5 The edges of the L-shaped bend structure 18 and the dovetail structure 19 are equipped with blades. Under normal circumstances, the L-shaped bend structure 18 is used for weeding. When the row spacing of crops is too narrow, in order to avoid the L-shaped bend structure 18 accidentally damaging the roots of crops, it can be replaced with the dovetail structure 19 mowing shovel 13. The mowing shovel 13 is relatively narrow, which is conducive to moving in narrow row spacing and also protects the crops from damage.

[0030] Specific embodiment 2 of the efficient and environmentally friendly automatic weeding device provided by this utility model:

[0031] Due to the unevenness of the field ridges, this embodiment optimizes the weeding assembly 7 based on embodiment 1 by adding a parallel four-bar linkage 21 to ensure that the mowing shovel 13 maintains a stable depth of penetration in undulating terrain and improves the uniformity of weeding. Specifically, the weeding assembly 7 also includes a mounting bracket 22 and a parallel four-bar linkage 21. The mounting bracket 22 is mounted on the rear beam 3 by two sets of U-bolts 24. The parallel four-bar linkage 21 is connected to the mounting bracket 22 and the longitudinal beam 8. A spring 25 is also provided on the parallel four-bar linkage 21. The spring 25 acts on the parallel four-bar linkage 21 to provide downward pressure, ensuring that the mowing shovel 13 always keeps close to the ground and avoids missed areas or excessive penetration due to uneven ground.

[0032] Specific embodiment 3 of the efficient and environmentally friendly automatic weeding device provided by this utility model:

[0033] This embodiment addresses the problem of crop row deviation caused by non-linear crop arrangement between rows (such as manual sowing or hilly terrain), which easily damages seedlings when using traditional straight-line weeding methods. This embodiment achieves real-time position fine-tuning of the weeding assembly 7 through a hinged beam frame and hydraulic steering system. Combined with a vision assistance system, it significantly improves the operational accuracy under complex planting conditions. Specifically, the front beam 2 and the rear beam 3 are connected by several sets of connecting parts 26. The connecting parts 26 are hinged to the front beam 2 and the rear beam 3, allowing the front beam 2 and the rear beam 3 to swing relative to each other. A left-right adjustment cylinder 27 is also installed between the front beam 2 and the rear beam 3. The piston rod of the left-right adjustment cylinder 27 is connected to the rear beam 3. The extension and retraction of the piston rod of the left-right adjustment cylinder 27 can push and pull the rear beam 3, causing it to swing horizontally relative to the front beam 2.

[0034] A seat bracket 28 is fixed in the middle of the front beam 2. The seat bracket 28 extends rearward and a seat 29 is installed on the seat bracket 28. A steering pump 30 is also installed on the front beam 2. The steering pump 30 is connected to a steering wheel 32 through a control lever 31. The steering pump 30 is connected to the left and right adjustment cylinders 27 through oil pipes. The steering pump 30 can be controlled by operating the steering wheel 32.

[0035] Furthermore, the weeding equipment also includes a camera 34 and a monitoring display screen. The camera 34 is mounted on the longitudinal beam 8, and the monitoring display screen is connected to the camera 34 via wiring. The camera 34 is waterproof and dustproof, and collects real-time data on the relative position of the mowing shovel 13 and the crops. The display screen assists the driver in observing the operation status in bumpy environments.

[0036] During operation, the operator sits on seat 29 and observes the crops between the rows. When the crop rows bend, the operator turns the steering wheel 32, the steering pump 30 outputs hydraulic oil, and the left and right adjustment cylinders 27 push and pull the rear beam 3, causing the rear beam 3 to shift laterally. Finally, the mowing shovel 13 adjusts its position synchronously, always maintaining a safe distance of 2cm from the seedlings.

[0037] Specific embodiment 4 of the efficient and environmentally friendly automatic weeding device provided by this utility model:

[0038] To address the issues of large space occupation and inconvenient transportation and storage when multiple weeding assemblies 7 (e.g., 6 assemblies) are deployed laterally, this embodiment innovatively adopts a foldable rear beam 3 design, which achieves rapid deployment and retraction through hydraulic drive, significantly improving the equipment's mobility and site adaptability; the specific structural design is as follows:

[0039] The rear beam 3 includes a central beam 37 and two folding rods 38. Four weeding assemblies 7 are installed on the central beam 37. The two folding rods 38 are respectively connected to both ends of the central beam 37 by hinges. Two sets of folding hydraulic cylinders 39 are also installed on the central beam 37. The piston rods of the folding hydraulic cylinders 39 are respectively connected to the upper part of the two folding rods 38. A weeding assembly 7 is installed on each folding rod 38.

[0040] During transportation, the folding cylinder 39 retracts, pulling the folding rods 38 on both sides, reducing the overall width by more than 30%. When deployed in the field, the folding cylinder 39 extends, and the folding rods 38 on both sides slowly lower to a horizontal position. After unfolding, the six weeding assemblies 7 are arranged in a straight line. This embodiment solves the pain points of transportation and storage of large weeding equipment by using a modular folding design, while retaining the full-function weeding performance.
