Description

Technical Field

[0001] The invention relates to the technical field of forestry, in particular to an agricultural mechanical weeding device. Background Art

[0002] A lawn mower is also known as a weed cutter, lawn mower, or lawn trimmer. A lawn mower is a mechanical tool used to trim lawns and vegetation. It consists of a cutter disc, an engine, running wheels, a running mechanism, a rotating blade, armrests, and a control unit. The cutter disc is mounted on the running wheels, and the engine is mounted on the cutter disc. The rotating blade is mounted on the engine's output shaft. The rotating blade utilizes the high-speed rotation of the engine to significantly increase the speed, saving workers time and reducing a large amount of manpower.

[0003] Patent application publication number CN115943763A describes an agricultural mechanical weeding device comprising a frame, a control box, and a lateral fine-tuning mechanism disposed on the underside of the frame; a binocular camera is disposed on top of the control box; the lateral fine-tuning mechanism comprises two transmission shafts, on which a plurality of connecting seats are fixedly disposed at equal intervals, each connecting seat being connected to a lifting drive mechanism at its bottom end; the lifting drive mechanism being fixedly connected at its bottom end to one end of the drive seat, and a shock-absorbing mechanism being connected between the other end of the drive seat and the frame; a servo motor and a weeding cutter connected thereto via a universal joint are disposed at the bottom end of the drive seat; the control box is electrically connected to the binocular camera, the reciprocating drive motor, the lifting drive mechanism, and the servo motor, respectively, and transmits control signals thereto;

[0011] Preferably, one end of the hinged barrier rod is hinged with a second hinge block, and the top of the second hinge block is fixedly connected with a slider.

[0012] Preferably, the inner wall of the second hinge block is hinged to the hinged barrier rod via a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a separation plate, which is an arc-shaped plate structure.

[0015] Preferably, a sliding bar is fixedly connected to the bottom of the weeder, and the top of the slider is slidably connected to the bottom of the weeder via the sliding bar.

[0016] Preferably, a distance sensor is fixedly connected to one side of the slider, an information processor is fixedly connected to the top of the weeder, a telescopic cover is fixedly connected to one side of the slider, one end of the telescopic cover is fixedly connected to the outer wall of the connecting shaft, and the distance sensor is located inside the telescopic cover.

[0017] Preferably, a display screen is provided on the surface of the information processor, and the distance sensor is electrically connected to the information processor.

[0018] Preferably, the information processor is square in shape, and the cross section of the sliding bar is T-shaped, and the sliding bar serves to enable the slider to slide left and right on it without falling.

[0019] The present invention provides an agricultural mechanical weeding device having the following beneficial effects:

[0020] 1. The present invention is provided with a weeding adaptation mechanism, so that while using the rotary blade to weed, the rotary blade can be automatically lifted up according to potholes and uneven protruding stones on the road surface. This can effectively prevent the tip of the rotary blade from hitting stones and soil when cutting and crushing weeds, causing the rotary blade to break and splash and injure people, and the soil to be damaged by the rotary blade, causing the lawn to have a condition similar to "alopecia areata". This protects both the workers and the soil used in forestry work, and increases the adaptability of the weeder to various types of uneven roads.

[0021] 2. The present invention provides a weeding adaptation mechanism. The rotating blade is pushed and lifted by the ground and stones due to the hinged barrier rod, so that the rotary blade can better adapt to the terrain when trimming the lawn. Therefore, when the height of the lawn is the same as the undulation of the underlying soil, the lawn can better fit the original terrain characteristics, creating a natural and harmonious beauty in forestry. More importantly, the undulating lawn is conducive to the natural drainage of rainwater. Rainwater will flow quickly along the height difference of the terrain, avoiding water accumulation on the lawn. For example, after a rainstorm, a flat lawn may have local water accumulation. However, for a lawn mowed according to the undulating terrain, water can quickly flow to the low-lying areas and be discharged, reducing the problems of lawn diseases and root rot caused by water accumulation, and improving its applicability to various lawn mowing work environments.

[0022] 3. The present invention provides a weeding adaptation mechanism. Under the elastic force of the spring, the telescopic shaft is driven to rotate while continuously vibrating up and down. At the same time, the connecting block and the rotating blade are also driven to vibrate up and down during the weeding operation. The up and down vibration is used to reduce the entanglement problem of the rotating blade with weeds when it is in a state of simple horizontal rotation for a long time. The up and down lifting process of the rotating blade can reduce the probability of the rotating blade being entangled during weeding, thereby ensuring the stability of weeding.

[0023] 4. The present invention is provided with a weeding adaptation mechanism to quickly disperse weeds that are crowded together or even partially knotted, and divide them into clusters through a number of evenly arranged grooves. The clusters are evenly arranged and enter the cutting range of the rotary blade, which not only reduces the burden of the rotary blade during weeding and reduces entanglement, but also increases the weeding efficiency. It prevents the crowded grass from being unable to be completely cut off by the rotary blade due to its thick structure. Then, the grass is bent and laid down by the impact force of the rotating blade. After the rotary blade passes, the bent and laid-down grass will lose the upper obstruction and stand up again, thus avoiding the unsightly problem of incomplete weeding and uneven lawn layers.

[0024] 5. The present invention provides a weeding adaptation mechanism to avoid bumps on the road surface and larger rocks. The separator plate not only separates and sorts the grass piles through the grooves, but also automatically raises the connecting block and the rotating blades when encountering higher rocks or bumps on the road surface. This eliminates the need for a hinged barrier to contact the rocks, thus avoiding the problem of larger rocks not facing the hinged barrier being hit by the rotating blades on both sides of the hinged barrier as it moves forward.

[0025] 6. The present invention is provided with an auxiliary mechanism. When the weed remover continuously encounters obstacles of stones of different sizes and uneven roads of different degrees, the information is automatically processed and converted into specific numerical values through the information processor, and displayed on the information processor. The staff pushing the handle can observe the numerical values on the information processor in real time to judge the road conditions below the weed remover at this time, which is convenient for the staff to understand and make corresponding adjustments in time, thereby improving the working stability of the weeding work and reducing the occurrence of accidents.

DETAILED DESCRIPTION

[0037] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: an agricultural mechanical weeding device, comprising a weeder 2, a motor 5 fixedly connected to the top of the weeder 2, a push handle 1 fixedly connected to the top of the weeder 2, rollers 6 installed on both sides of the weeder 2 through a connecting shaft 7, and a weeding adaptation mechanism 3 provided at the bottom of the weeder 2;

[0038] Weed control adaptation mechanism 3 includes:

[0039] A telescopic shaft 301, one end of which is fixedly connected to the output end of the motor 5. The outer wall of the telescopic shaft 301 is rotatably connected to the bottom of the weeder 2 via a first bearing 302. A connecting block 305 is fixedly connected to the outer wall of the telescopic shaft 301. A rotating blade 306 is fixedly connected to the bottom of the connecting block 305. The motor 5 is used to control the telescopic shaft 301 to drive the connecting block 305 and the rotating blade 306 to rotate.

[0040] Spring 307, one end of the spring 307 is fixedly connected to the top of the connecting block 305. The telescopic shaft 301 is divided into three sections. The top of the spring 307 is fixedly connected to the bottom of the topmost telescopic shaft 301. The spring 307 is used to reset the connecting block 305.

[0041] When in use, the forestry worker pushes the handle 1 by hand, so that the weeder 2 moves on the lawn that needs to be leveled and weeded via the roller 6, and synchronously starts the motor 5 to control the rotation of the telescopic shaft 301, the connecting block 305 and the rotating blade 306. When the rotating blade 306 rotates rapidly, the weeds at the bottom of the weeder 2 are broken up to remove the weeds;

[0042] Example 2: Please refer to Figure 1-9On the basis of the first embodiment, the present invention provides a technical solution: on the one hand, when the rotary blade encounters raised stones or clods of earth during the weeding process, the tip of the rotary blade is very likely to collide violently with these hard objects, which will not only cause the rotary blade to crack and splash, posing a serious safety hazard to the operator, but also damage the surface of the soil, causing damaged areas similar to "alopecia areata" on the lawn, affecting the overall appearance and subsequent growth of the lawn.

[0043] On the other hand, traditional weed control equipment uses a rotating blade that rotates horizontally for extended periods of time. This can easily lead to weed entanglement during contact with weeds. This entanglement problem is particularly severe when weeds are dense or even tangled. This not only increases the rotational resistance of the blades, significantly reducing weed control efficiency, but also makes weed control unstable, potentially resulting in incomplete weed control and uneven layers of the lawn after mowing, seriously affecting the lawn's natural and harmonious aesthetic.

[0044] Furthermore, the distribution of weeds during weeding can also affect the effectiveness of the weeding process. If weeds are crowded together, especially if some are tangled, the rotary blades will have difficulty completely severing them. The remaining weeds will bend and fall flat due to the impact of the rotation of the blades. These bent weeds will then stand up again after the weeding equipment passes, resulting in suboptimal weeding and requiring multiple rework, increasing labor intensity and time costs.

[0045] Furthermore, after rainy days, flat lawns are prone to localized waterlogging. This waterlogging can lead to lawn diseases and root rot, affecting the healthy growth of the lawn. Traditional weeding equipment cannot adapt to the terrain, hindering the natural drainage of rainwater. Therefore, a second bearing 308 is fixedly connected to the bottom of the telescopic shaft 301. A first hinge block 310 is fixedly connected to the bottom of the second bearing 308. The first hinge block 310 is hingedly connected to a hinged stopper 311.

[0046] One end of the hinged blocking rod 311 is hinged to a second hinge block 312 , and the top of the second hinge block 312 is fixedly connected to a slider 309 .

[0047] The inner wall of the second hinge block 312 is hinged to the hinged blocking rod 311 via a rotating shaft 314 , and the outer wall of the rotating shaft 314 is fixedly connected to a separation plate 313 , which is an arc-shaped plate structure.

[0048] A guide bar 316 is fixedly connected to one side of the separation plate 313. The cross section of the guide bar 316 is an isosceles triangle. A groove 315 is opened on the inner wall of the separation plate 313. An arc-shaped piece 317 is fixedly connected to the bottom of the hinged barrier rod 311.

[0049] When weeding the lawn, the hinged stopper 311 hinged under the second bearing 308 at the bottom of the telescopic shaft 301 will contact the soil road surface at the bottom, and the other end of the hinged stopper 311 is hinged on the second hinge block 312 below the slider 309. Since the slider 309 is fixed in height, when the soil road surface is uneven, the hinged stopper 311 below will be held by the raised soil and stones, and push the hinged stopper 311 upward to the first hinge block 310 and the second bearing 308, so that the second bearing 308 pushes the telescopic shaft 301 to rise, the telescopic shaft 301 shortens step by step, and drives the connecting block 305 and the rotating blade 306 on the outer wall of the telescopic shaft 301 to rise synchronously. The bottom end of the weed cutter 306 is rotatably connected to the first hinge block 310 via the second bearing 308, so the hinged stopper 311 can push the telescopic rotating shaft 301 to rotate and extend, thereby realizing that while the rotating blade 306 is weeding, the rotating blade 306 can be automatically lifted up according to the potholes and uneven protruding stones on the road surface. This can effectively prevent the tip of the rotating blade 306 from hitting stones and soil when the rotating blade 306 cuts and crushes weeds, causing the rotating blade 306 to break and splash and injure people, and the soil being damaged by the rotating blade 306, causing the lawn to have a condition similar to "alopecia areata". This protects both the workers and the soil used in forestry work, and increases the adaptability of the weed cutter 2 to various types of uneven roads.

[0050] The rotating blade 306 is pushed and lifted by the ground and rocks because of the hinged stop bar 311, so that the lawn trimming by the rotating blade 306 can be more adapted to the terrain. Therefore, when the height of the lawn is the same as the undulation of the bottom soil, the lawn can better fit the original terrain characteristics, creating a natural and harmonious beauty in forestry. More importantly, the undulating lawn is conducive to the natural drainage of rainwater. Rainwater will flow quickly along the height difference of the terrain, avoiding water accumulation on the lawn. For example, after a rainstorm, a flat lawn may have local water accumulation. However, for a lawn trimmed according to the undulating terrain, water can quickly flow to the low-lying areas and be discharged, reducing the problems of lawn diseases and root rot caused by water accumulation, and improving its applicability to various lawn mowing work environments.

[0051] When the hinged stopper 311 always adheres to the muddy ground and moves forward, the unevenness of the road surface will be transmitted to the hinged stopper 311 to the second bearing 308 and the telescopic shaft 301. As a result, under the elastic force of the spring 307, the telescopic shaft 301 is driven to rotate and continuously vibrates up and down, and at the same time drives the connecting block 305 and the rotating blade 306 to vibrate up and down when rotating to weed. The up and down shaking is used to reduce the problem of the rotating blade 306 being entangled with weeds when it is in a state of simple horizontal rotation for a long time. The up and down lifting process of the rotating blade 306 can reduce the probability of the rotating blade 306 being entangled during weeding, thereby ensuring the stability of weeding.

[0052] When the weeder 2 is pushed forward, the weeds will first come into contact with the separation plate 313 and be separated by the grooves 315 in the inner wall of the separation plate 313, so that the weeds that are crowded together or even partially tangled into a ball will be quickly scattered and divided into clusters by a number of evenly arranged grooves 315. The clusters are evenly arranged and enter the cutting range of the rotary blade 306, which not only reduces the burden of the rotary blade 306 when weeding and reduces entanglement, but also increases the weeding efficiency, and avoids the crowded grass being unable to be completely cut off by the rotary blade 306 due to its thickness, and then being bent down by the impact force of the rotary blade 306. After the rotary blade 306 passes, the bent grass will stand up again without the upper obstruction, thus avoiding the unsightly problem of incomplete weeding and uneven lawn layers.

[0053] The guide strip 316 on one side of the separation plate 313 has a triangular cross-section. When it comes into contact with the grass, the guide strip 316 guides the grass more evenly into the groove 315, thus preventing the grass from being crowded and difficult to enter the groove 315.

[0054] When the hinged barrier rod 311 is lifted by the stone, one end is hinged on the first hinge block 310 to push the second bearing 308 upward, while the other end is hinged through the second hinge block 312 to push the slider 309 to slide rightward on the sliding bar 402, giving the hinged barrier rod 311 space to be flattened when hinged and rotated.

[0055] Example 3: Please refer to Figure 1-10 Based on the first and second embodiments, the present invention provides a technical solution: when the weeding equipment encounters larger stones during its forward movement, the position of the larger stones is not directly opposite the avoidance components similar to the hinged barrier lever in the traditional equipment, but is located on both sides of its forward path. The rotating blade may still hit these stones during the normal weeding process, further increasing the risk of damage to the rotating blade.

[0056] On the other hand, during the weeding process, workers often have difficulty understanding the road conditions below the weeding equipment in real time. Unable to accurately grasp the distribution of obstacles and the undulations of the terrain, workers may misjudge when operating the equipment, causing the equipment to collide with obstacles, or fail to adjust the weeding strategy in time to adapt to different road conditions. This not only affects the stability of the weeding work, but also increases the probability of accidents. Therefore, an auxiliary mechanism 4 is provided on the outer wall of the hinged barrier 311. The auxiliary mechanism 4 includes a fixed plate 401 fixedly connected to both sides of the hinged barrier 311. The fixed plate 401 is a rectangular plate structure.

[0057] A sliding bar 402 is fixedly connected to the bottom of the weeder 2 , and the top of the slider 309 is slidably connected to the bottom of the weeder 2 via the sliding bar 402 .

[0058] A distance sensor 403 is fixedly connected to one side of the slider 309, and an information processor 404 is fixedly connected to the top of the weeder 2. The distance sensor 403 is electrically connected to the information processor 404. A telescopic cover 405 is fixedly connected to one side of the slider 309, and one end of the telescopic cover 405 is fixedly connected to the outer wall of the connecting shaft 7. The distance sensor 403 is located inside the telescopic cover 405.

[0059] The information processor 404 is provided with a display screen on its surface, and the distance sensor 403 is electrically connected to the information processor 404 .

[0060] The information processor 404 is square in shape, and the cross section of the sliding bar 402 is T-shaped. The sliding bar 402 serves to prevent the slider 309 from sliding left and right on it.

[0061] When the separating plate 313 encounters a smaller stone in front, it will be naturally pushed up by the stone, driving the rotating shaft 314 to rotate synchronously, allowing the small stone that does not affect the weeding to pass. When it encounters a larger stone or a raised road surface, the separating plate 313 is pushed upward and rotated until the separating plate 313 contacts the fixed plate 401 and continues to push the fixed plate 401 to the hinged stopper 311. The stone and the ground will continue to move along the inclined separating plate 313 and the hinged stopper 311 to lift the left side of the hinged stopper 311, and finally the telescopic rotating shaft 30 1. The connecting block 305 and the rotating blade 306 are lifted up as a whole to avoid bumps on the road surface and larger stones. The separating plate 313 can not only separate and sort the grass pile through the groove 315, but also automatically lift the connecting block 305 and the rotating blade 306 when encountering higher stones and bumps on the road surface, without the need for the hinged barrier 311 to contact the stones. This avoids the problem that larger stones are not directly facing the hinged barrier 311 and are hit by the rotating blade 306 on both sides of the hinged barrier 311 when it moves forward;

[0062] When encountering obstacles of different sizes of stones and uneven roads of different degrees continuously, the larger the convex surface and the stones, the higher the height of the connection block 305 and the rotating blade 306 will be. The higher the height of the connection block 305 and the rotating blade 306 is, the farther the slider 309 is moved to the right on the sliding bar 402 by the hinged blocking rod 311. Therefore, the distance sensor 403 on one side of the slider 309 will send the information to the information processor 404 by identifying the distance between the slider and the connecting shaft 7. The information processor 404 automatically processes the information and converts it into a specific value, which is displayed on the information processor 404. The staff who pushes the push handle 1 can observe the value on the information processor 404 in real time to judge the road condition below the weeder 2 at this time, which is convenient for the staff to understand and make corresponding adjustments in time, thereby improving the working stability of the weeding work and reducing the occurrence of accidents.

[0063] The distance sensor 403 is covered by a telescopic cover 405 between it and the connecting shaft 7, which can prevent external weeds and debris from interfering with the distance recognition of the distance sensor 403. As the position of the slider 309 moves left and right, the telescopic cover 405 can freely extend and retract without obstructing the slider 309. The telescopic cover 405 covers the distance sensor and is hollow inside, which will not affect the distance sensing of the distance sensor 403 to the connecting shaft 7.

[0064] The arc piece 317 is used to contact the stone instead of the hinged barrier rod 311 when the hinged barrier rod 311 contacts the stone. The smaller contact area of the arc piece 317 can reduce the friction between the stone and the hinged barrier rod 311, thereby improving the smoothness of sliding.

[0065] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
