Description

Technical Field

[0001] This utility model relates to the field of automatic weeding equipment technology, specifically an automatic weeding device with adjustable weeding depth. Background Technology

[0002] Automated weeding machines are agricultural machines that utilize advanced technology to achieve unmanned or semi-automated operation. They are designed to efficiently and accurately remove weeds from farmland, reduce manual labor, and improve agricultural production efficiency. With the acceleration of agricultural modernization, automated weeding machines have gradually become an important part of modern agriculture. Among them, Chinese Patent No. CN202422840746.5 provides an automated weeding and spraying device for farmland, which includes a pushing component; it also includes a moving plate, an L-shaped block, a protective component, a spraying component, and a cutting component. This invention utilizes a second motor to drive a rotating rod that rotates the cutting blade at high speed, enabling the cutting and pulverizing of weeds in farmland. Activating the braking mechanism on the moving plate allows it to move back and forth on the upper part of the pushing component, causing the L-shaped block to move in the forward and backward direction, thus expanding the weeding range. The protective component supports the spraying assembly, and the external hose is installed on the water inlet of the nozzle. The second electric cylinder is then activated to adjust the angle of the rotating block, and the third electric cylinder is activated to adjust the height of the fixing sleeve, allowing for rapid adjustment of the spray angle. A pressurized mixture of nutrient solution and water is then introduced into the nozzle and sprayed onto the weeded land.

[0003] Based on the above, the inventors have discovered the following problems: the above-mentioned device can effectively cut and crush weeds and spray nutrient solution on the weeded land; however, it overlooks the fact that in existing automatic weeding equipment, when crossing ground at different heights, the cutter in the automatic weeding equipment may collide with the ground, causing damage to the cutter and scattering dust on the ground, resulting in poor visibility of the working environment and the camera device in the weeding equipment.

[0020] 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.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example:

[0023] In this embodiment, an automatic weeding device with adjustable weeding depth includes a vehicle body 1. Tracked wheels 2 are provided on both sides of the vehicle body 1. A power mechanism is provided between a pair of tracked wheels 2. A fixing plate 3 is fixed to the upper end of one side of the vehicle body 1. A hydraulic telescopic rod 4 is provided on the upper end of the fixing plate 3. The output end of the hydraulic telescopic rod 4 is vertically downward. A moving plate 5 is provided at the output end of the hydraulic telescopic rod 4. A rotating motor 8 is provided on the moving plate 5. A connecting plate 6 is connected to the lower end of the moving plate 5. The output end of the rotating motor 8 is vertically downward and is provided with a drive sprocket 11. An annular chain 10 is sleeved on the drive sprocket 11. Chain 10 is connected to several drive sprockets 9, each drive sprocket 9 is connected to a bearing 14, the bearing 14 is connected to a connecting plate 6, the lower end of each drive sprocket 9 is provided with a connecting block, the connecting block extends into the lower end of the connecting plate 6 and is provided with a blade 7, the blade 7 is provided with a through hole 13, the through hole 13 is connected to the connecting block and the drive sprocket 9, the through hole 13 is provided with a connecting post 15, the upper end of the connecting post 15 passes through the through hole 13 and is connected to the lower end of the fixed plate 3 through the moving plate 5, the lower end of the connecting post 15 is movably provided with a sensing plate 12, the lower end of the sensing plate 12 is provided with a pair of wheels 25, and the connecting post 15 is provided with a movable component;

[0024] When the height of the blade 7 needs to be adjusted, the hydraulic telescopic rod 4 can be activated to move the moving plate 5 in the vertical direction, thereby moving the blade 7 and the connecting plate 6 in the vertical direction. This allows for adjustment of the cutting depth of the device on weeds. The blade 7 cuts weeds by rotating at high speed. The rotating motor 8 drives the drive gear 11 to rotate. With the combination of the ring chain 10 and several transmission gears 9, several blades 7 are driven to rotate and cut weeds. Through the bearing 14, the rotational force of the transmission gears 9 can be transmitted to the blade 7 through the connecting block without affecting the integrity of the connecting plate 6.

[0025] The movable component includes slots 24, a pair of slots 24 are formed on the side of the connecting post 15, a V-shaped part 23 is provided inside the connecting post 15 and above the sensing plate 12, an arc wheel 22 is attached to the upper end of the V-shaped part 23, a movable part 21 is provided at the upper end of the arc wheel 22, the movable part 21 is movably connected to the slots 24 on both sides, a movable shaft 16 is provided at the upper end of the movable part 21, a spring 20 is sleeved on the movable shaft 16, a fixed plate 19 is provided inside the connecting post 15 and above the spring 20, a round hole is formed on the fixed plate 19, the movable shaft 16 passes through the round hole on the fixed plate 19 and extends out of the upper end of the fixed plate 19, a camera capture device 17 is provided inside the connecting post 15 and above the fixed plate 19, and a sensing ring 18 is provided at the upper end of the movable shaft 16;

[0026] The distance between the wheel 25 and the sensing plate 12 is much greater than the radius of the blade 7, so that when the height of the ground in front of the device changes, the wheel 25 can contact the ground in front of the device before the blade 7.

[0027] The sensing ring 18 is horizontally aligned with the camera capture device 17. A data processor is installed inside the vehicle body 1. The camera capture device 17 is communicatively connected to the data processor. A controller is installed on the hydraulic telescopic rod 4. The controller is communicatively connected to the data processor.

[0028] Through the design of the sensing plate 12, when the wheel 25 at one end of the sensing plate 12 moves to a higher ground, the wheel 25 and the side of the sensing plate 12 facing the wheel 25 move upward under the pressure of the ground, driving the V-shaped component 23 to rotate upward in the same direction around the center of the V-shaped component 23. Figure 4 As shown, the arc-shaped wheel 22 is pushed to move vertically upward, causing the movable part 21 and the movable shaft 16 to move upward in the same direction within the connecting column 15. When the movable shaft 16 moves upward, the position of the sensing ring 18 and the camera capture device 17 is misaligned. The camera capture device 17 can identify and capture the rising distance of the sensing ring 18, and then transmit the information to the data processor in the vehicle body 1. The data processor then sends the information to the controller in the hydraulic telescopic rod 4, which controls the hydraulic telescopic rod 4 to start, so that the retracted length of the hydraulic telescopic rod 4 is the same as the upward movement length of the wheel 25. The retraction of the hydraulic telescopic rod 4 drives the moving plate 5 and the blade 7 to move upward, thereby avoiding the blade 7 from colliding with the higher ground in front, which would damage the blade 7 and thus extend the service life of the device.

[0029] The lower end of the spring 20 is connected to the upper end of the movable part 21, and the upper end of the spring 20 is connected to the lower end of the fixed plate 19.

[0030] By designing the spring 20, when the sensing plate 12 vibrates during the movement of this device, the amplitude of the vibration of the moving plate 5 and several blades 7 on this device can be reduced, thus avoiding affecting the mowing operation of the blades 7.

[0031] Among them, the pair of slots 24 are horizontally aligned with the movable part 21 and the V-shaped part 23.

[0032] Among them, the movable part 21, the V-shaped part 23, the fixed plate 19 and the camera capture device 17 are all vertically aligned, and the lower end of the wheel 25 is horizontally aligned with the lower end of the track wheel 2;

[0033] The design of the movable part 21 and a pair of slots 24 makes the vertical movement of the movable shaft 16 more stable.

[0034] The upper end of the movable plate 5 is provided with several limiting rods, and the fixed plate 3 is provided with several limiting holes. The upper end of the limiting rod passes through the limiting hole and extends out of the upper end of the fixed plate 3.

[0035] The design of the limiting rod and limiting hole makes the vertical movement of the moving plate 5 more stable and smooth.

[0036] Working principle: In use, the rotating motor 8 drives the drive gear 11 to rotate. Under the combination of the ring chain 10 and several transmission gears 9, several blades 7 rotate to cut weeds. Through the bearing 14, the rotational force of the transmission gears 9 can be transmitted to the blades 7 through the connecting block without affecting the integrity of the connecting plate 6. When it is necessary to adjust the height of the blades 7, the hydraulic telescopic rod 4 can be activated to move the moving plate 5 in the vertical direction, thereby moving the blades 7 and the connecting plate 6 in the vertical direction, thus adjusting the cutting depth of the device on the weeds.

[0037] Furthermore, when the wheel 25 at one end of the sensing plate 12 moves to a higher ground, the wheel 25 and the side of the sensing plate 12 facing the wheel 25 move upward under the pressure of the ground, causing the V-shaped component 23 to rotate upward in the same direction around the center of the V-shaped component 23. Figure 4As shown, the arc-shaped wheel 22 is pushed to move vertically upward, causing the movable part 21 and the movable shaft 16 to move upward in the same direction within the connecting column 15. When the movable shaft 16 moves upward, the position of the sensing ring 18 and the camera capture device 17 is misaligned. The camera capture device 17 can identify and capture the rising distance of the sensing ring 18, and then transmit the information to the data processor in the vehicle body 1. The data processor then sends the information to the controller in the hydraulic telescopic rod 4, which controls the hydraulic telescopic rod 4 to start, so that the retracted length of the hydraulic telescopic rod 4 is the same as the upward movement length of the wheel 25. The retraction of the hydraulic telescopic rod 4 drives the moving plate 5 and the blade 7 to move upward, thereby avoiding the blade 7 from colliding with the higher ground in front, which would damage the blade 7 and thus extend the service life of the device.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
