Detailed Implementation

[0028] 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.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In forestry operations, weeding and pesticide application are crucial for maintaining ecological balance and promoting tree growth. Existing forestry weeding devices are mostly single-function designs, such as purely mechanical mowing equipment or independent spraying devices. These devices suffer from inefficiencies and cumbersome operation in practical applications. Traditional mowing devices are typically based on a cart-like structure, equipped with rotating blades or cutting discs, and clear weeds by manual pushing or small-scale power. For example, some devices have motor-driven rotating blades mounted on a mobile cart, using high-speed rotation to cut weed stems. However, the cutting range is limited by the blade layout, and there is a lack of immediate post-cut weed treatment, requiring subsequent manual cleaning or secondary pesticide application. Furthermore, while some devices attempt to integrate spraying functions, the liquid storage tank and spraying system are often independently set up, with complex piping connections and limited spray coverage, making it difficult to achieve coordinated weeding and pesticide application.

[0031] Regarding ease of operation, existing devices largely rely on threaded fasteners for lever height adjustment. For example, some trolley-type weed cutters use a bolt-and-nut fastening method, requiring complete bolt removal, manual alignment of the connecting groove and positioning hole, and re-tightening during adjustment. This process not only necessitates carrying specialized tools but also leads to thread wear from repeated tightening, affecting adjustment efficiency and structural stability. Some improved designs attempt to simplify the adjustment process with segmented snap-fit ​​structures, but the locking strength of the snaps is insufficient, making them prone to accidental loosening under equipment vibration or stress, posing a safety hazard. Furthermore, traditional adjustment mechanisms lack guiding design, requiring operators to repeatedly adjust the lever position to ensure alignment during adjustment, further reducing operational continuity.

[0032] For pesticide spraying systems, common designs in existing technologies include fixed nozzles and adjustable nozzles. Fixed nozzles are usually installed at the bottom or side of the equipment, resulting in a single spray direction and uneven pesticide distribution, especially prone to coverage blind spots in complex terrain. Some equipment uses rotatable nozzles or telescopic nozzles to expand the coverage area, but such structures often rely on manual adjustment, making it impossible to adjust the spray angle in real time during operation, leading to low pesticide utilization. In addition, the pesticide in the storage tank is prone to sedimentation and stratification due to prolonged standing, affecting the spraying effect. Although some equipment adds a stirring device, the layout of the stirring blades is unreasonable, the mixing effect is limited, and the stirring power is not effectively coordinated with the spraying system, increasing energy consumption and structural complexity.

[0033] In terms of mobile structure design, existing forestry weeding devices mostly adopt wheeled or tracked chassis to adapt to different terrains. Wheeled structures are lightweight and flexible, but they are prone to getting stuck or slipping on soft or rugged ground; tracked structures, while having strong passability, are heavy and difficult to steer, making them unsuitable for small-scale forest operations. Some equipment attempts to improve passability through adjustable wheel track or suspension systems, but the adjustment mechanisms are complex and maintenance costs are high. In addition, the functional module layout of traditional mobile carts lacks integration; for example, the cutting and spraying components are placed at the front and rear ends, causing the equipment's center of gravity to shift, affecting its stability, and making it prone to tipping over, especially when operating on slopes.

[0034] To address the issue of pesticide mixing, existing technologies often employ simple cavity structures for the storage tank, relying on natural diffusion or low-speed stirring to dissolve the pesticide. This design results in poor mixing of viscous pesticides or high-concentration formulations, and undissolved particles easily clog nozzles, affecting spray continuity. Some high-end equipment is equipped with high-speed stirring motors, but the sealing structure between the motor and the storage tank is inadequate, leading to leaks over time and increased maintenance frequency. Furthermore, the filling port is typically directly exposed to the external environment, lacking effective dust protection. Impurities entering the storage tank accelerate pipe wear and shorten equipment lifespan.

[0035] In terms of power transmission for the cutting components, traditional designs often employ belt drives or gearbox structures to transmit motor power to the rotating blades. Belt drives are simple, but prone to slippage or aging in humid environments; gearboxes, while highly efficient, require significant lubrication and are susceptible to wear due to impurities in dusty forestry environments. Furthermore, blades are typically bolted, requiring the removal of multiple fasteners for replacement or maintenance, which is time-consuming. Some equipment attempts to use quick-release mechanisms, but insufficient locking strength leads to vibration and noise during high-speed rotation, affecting cutting accuracy and safety.

[0036] In summary, existing forestry weeding devices still have significant shortcomings in terms of functional integration, ease of adjustment, spraying effect, and structural reliability. Single-function devices lead to fragmented work processes, requiring operators to frequently switch tools; height adjustment relies on threaded fasteners, reducing operational efficiency; uneven coverage and insufficient pesticide mixing in the spraying system affect application quality; and complex mechanical structures increase maintenance costs and the risk of malfunction. These problems restrict the overall efficiency and applicability of forestry weeding operations, necessitating innovative design to optimize functionality and improve performance.

[0037] Please see Figure 1-4 As shown, this embodiment provides a multifunctional forestry weeding device, including: a mobile trolley 1, on which a cutting component and a spraying component are provided, and two first square rods 5 are installed on one side of the mobile trolley 1. The spraying component is located between the cutting component and the first square rods 5. Square tubes 6 are slidably fitted around the first square rods 5, and the upper part of the first square rods 5 is located inside the square tubes 6. Handles 7 are installed on the upper parts of the two square tubes 6.

[0038] Both square tubes 6 have channels 601 on their inner sides. Multiple slots 602 are provided on the upper and lower sides of the channels 601. The channels 601 and slots 602 are connected to the inner cavity of the square tubes 6. The slots 602 penetrate one side of the square tubes 6. A guide is installed between the upper parts of the two first square rods 5. The guide passes through the two channels 601 laterally. Two sleeves 8 are slidably fitted on the periphery of the guide. Connecting blocks 801 and circular plates 802 are respectively installed on the two end faces of the sleeves 8. The circular plates 802 are located between the two sleeves 8. The connecting blocks 801 and circular plates 802 are slidably fitted on the periphery of the guide. The connecting blocks 801 are located in the corresponding channels 601. There are locking blocks on the upper and lower sides of the connecting blocks 801. The locking blocks are engaged in the corresponding slots 602. A spring 10 is provided between the two circular plates 802. The spring 10 is sleeved on the periphery of the guide.

[0039] One application of this embodiment is as follows: In use, the operator first moves the trolley 1 by holding the handle 7, at which time the cutting component cuts the weeds on the ground, and the spraying component sprays pesticide simultaneously. When it is necessary to adjust the height of the handle 7, the operator holds the two sleeves 8 with both hands and squeezes them together, causing the circular plate 802 to compress the spring 10, so that the locking block on the connecting block 801 disengages from the slot 602 of the square tube 6. At this time, the square tube 6 can slide up and down along the first square rod 5. After adjusting to the appropriate height, the sleeves 8 are released, and the spring 10 rebounds, pushing the circular plate 802 outward, causing the connecting block 801 to re-lock the locking block into the slot 602 of the corresponding height to complete the fixation. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0040] By sliding the square tube 6 and the first square rod 5, and by engaging the slot 602 and the block, combined with the spring 10 located between the two circular plates 802, the two sleeves 8 can be elastically slidably adjusted. This facilitates quick adjustment of the height of the handle 7, eliminates the need for bolt disassembly, improves adjustment efficiency, reduces tool dependence and the risk of thread wear. At the same time, the cooperation between the guide and the sleeve 8 ensures that the connecting block 801 and the slot 602 are precisely aligned during the adjustment process, improving locking reliability.

[0041] like Figure 4 As shown, the guide component in this embodiment includes a second square rod 502, a circular plate 802 slidably fitted around the second square rod 502, a spring 10 sleeved around the second square rod 502, and guide rods 501 mounted on the inner sides of the two first square rods 5 respectively. The guide rods 501 transversely penetrate the corresponding channels 601. The second square rod 502 is installed between the two guide rods 501. The sleeve 8 and the connecting block 801 are slidably fitted around the corresponding guide rods 501. Through the guiding structure of the second square rod 502 and the guide rods 501, the straightness of the sliding path of the sleeve 8 is enhanced, and the connecting block 801 is prevented from rotating and misaligning with the channel 601.

[0042] like Figure 4 As shown, in this embodiment, the two circular plates 802 are respectively equipped with an outer cylinder 803 and an inner cylinder 804 on their opposite inner end faces. The outer cylinder 803 and the inner cylinder 804 are both located on the periphery of the spring 10. One end of the inner cylinder 804 is slidably fitted inside the outer cylinder 803. Through the nested sliding structure of the outer cylinder 803 and the inner cylinder 804, the probability of the user being injured by contact with the spring 10 is reduced.

[0043] like Figure 4 As shown, the sleeve 8 in this embodiment is equipped with an anti-slip grip 9 on its periphery. The anti-slip grip 9 is located between the circular plate 802 and the corresponding connecting block 801. The anti-slip grip 9 increases the contact friction between the operator and the sleeve 8, making it easier to apply force to squeeze the sleeve 8 with both hands, reducing the risk of slipping during adjustment, and improving grip comfort.

[0044] like Figure 1 , 2 As shown, the cutting assembly in this embodiment includes a first motor 2 mounted on the upper side of the mobile trolley 1. The output shaft of the first motor 2 is fixedly connected to a rotating column 201. The rotating column 201 vertically penetrates the mobile trolley 1. Multiple grass-cutting blades 202 are evenly mounted on the lower periphery of the rotating column 201. The grass-cutting blades 202 are located below the mobile trolley 1. The first motor 2 drives the rotating column 201 to drive the grass-cutting blades 202 to rotate synchronously, thereby enhancing the coverage and work intensity of the cutting assembly, improving weeding efficiency, and achieving effective cutting of shrubs.

[0045] like Figure 1-3As shown, the spraying assembly of this embodiment includes a storage tank 3 mounted on the upper side of the mobile trolley 1. A liquid filling pipe 301 is provided on the upper side of the storage tank 3, and the liquid filling pipe 301 is connected to the inner cavity of the storage tank 3. A dust cover is threaded onto the top of the liquid filling pipe 301. The upper and lower sides of the mobile trolley 1 are respectively provided with a connected equipment slot 102 and a cross slot 101. The equipment slot 102 is located on the upper side of the cross slot 101. A water pump 11 connected to the storage tank 3 is installed in the equipment slot 102. A spraying pipe assembly connected to the water pump 11 is installed in the cross slot 101. Through the connection design between the storage tank 3, the water pump 11, and the spraying pipe assembly, the storage and spraying of pesticides are integrated, which facilitates the coordinated operation of weeding and pesticide application. At the same time, the layered layout of the equipment slot 102 and the cross slot 101 optimizes the space utilization and ensures the stability of the pipeline connection.

[0046] like Figure 3 As shown, the spray pipe assembly of this embodiment includes a horizontal pipe 12 installed between the two sides of the horizontal groove 101. Multiple nozzles 13 are connected to the bottom of the horizontal pipe 12. A liquid supply pipe 14 is connected between the water pump 11 and the horizontal pipe 12. Through the distributed spraying structure of the horizontal pipe 12 and multiple nozzles 13, the coverage area of ​​the agent is expanded and the uniformity of the application is improved.

[0047] like Figure 1-3 As shown, a second motor 4 is installed on the upper side of the storage tank 3 in this embodiment. The output shaft of the second motor 4 passes through the storage tank 3. The output shaft of the second motor 4 is fixedly connected to a rotating rod 401. Multiple stirring blades 402 are installed on the side of the rotating rod 401. The rotating rod 401 and the stirring blades 402 are rotatably engaged in the storage tank 3. The stirring blades 402 are located between the liquid addition pipe 301 and the water pump 11. The second motor 4 drives the rotating rod 401 and the stirring blades 402 to continuously stir the agent in the storage tank 3, preventing the agent from settling and separating, and ensuring the consistency of the spray concentration. The arrangement of the stirring blades 402 between the liquid addition pipe 301 and the water pump 11 enhances the mixing effect and reduces the probability of undissolved substances entering the pipeline and causing blockage.
