Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a hydraulic weeding device 100, which is beneficial to improving weeding efficiency and reducing weeding costs.

[0021] See Figure 1The present invention provides a water-powered weeding device 100, comprising a frame 10, with wheels 101 on both sides of the bottom of the frame 10, and a connecting part for connecting to a traction vehicle at the front of the frame 10; a nozzle support plate 11 on the frame 10, with multiple nozzle mounting holes 111 on the nozzle support plate 11; multiple pressurized water nozzles 12, each pressurized water nozzle 12 being fixed in a corresponding nozzle mounting hole 111, and the pressurized water jetting end of each pressurized water nozzle 12 extending from the corresponding nozzle mounting hole 111 and located at the bottom of the frame 10; and a pressurized water supply device, which is connected to the pressurized water supply end of each pressurized water nozzle 12.

[0022] The frame 10 is equipped with wheels 101 on both sides and a connecting part at the front to ensure that the frame 10 can move smoothly under external forces. The pressurized water nozzle 12 is fixed on the nozzle support plate 11 with nozzle mounting holes 111 to avoid uneven pressurized water spraying caused by shaking. The pressurized water nozzle 12 is located at the bottom of the frame 10 to better direct the pressurized water flow to the roots of weeds. In addition, the pressurized water nozzle 12 can be made into different shapes for different crops to meet the requirements of the planted plants. The pressurized water supply device is connected to the pressurized water supply end of each water pressure head to ensure the pressurized water supply in the water pressure head, and the pressure coefficient of the pressurized water can be adjusted according to actual use needs.

[0023] This utility model provides a hydraulic weeding device 100. The frame 10 has wheels 101 on both sides to facilitate movement of the frame 10. The front of the frame 10 has a connecting part for connecting with an external towing vehicle. The frame 10 also has a nozzle support plate 11 with multiple nozzle mounting holes 111. The pressurized water nozzle 12 is located at the bottom of the frame 10 and passes through the nozzle mounting holes 111. At the same time, the pressurized water supply end of the pressurized water nozzle 12 is connected to a pressurized water supply device, thereby controlling the pressurized water nozzle 12 to use the pressurized water supplied by the pressurized water supply device to cut the weeds. Compared with the existing manual weeding, it improves the weeding efficiency and reduces the labor cost of weeding.

[0024] like Figure 2 As shown, in some embodiments, the pressurized water spray direction of each pressurized water nozzle 12 is consistent with the walking direction of the frame 10; in this way, the pressurized water can directly contact the weeds and act on them, and this can make the flow path of the pressurized water more direct and reduce the dispersion of the water flow.

[0025] like Figure 2As shown, in some embodiments, the plurality of pressurized water nozzles 12 include a first nozzle group and a second nozzle group; the first nozzle group includes two or more first pressurized water nozzles 121, which are arranged side-by-side at intervals along a first horizontal line; the second nozzle group includes two or more second pressurized water nozzles 122, which are arranged side-by-side at intervals along a second horizontal line; wherein the first and second horizontal lines are parallel, and the two or more second pressurized water nozzles 122 are staggered with the two or more first pressurized water nozzles 121; wherein the parallel and staggered arrangement of the first pressurized water nozzles 121 in the first nozzle group and the second pressurized water nozzles 122 in the second nozzle group along the horizontal line can better control the distribution of sprayed water, ensure the density of the sprayed high-pressure water flow, and help improve the efficiency of weeding. like Figure 2 As shown, in some embodiments, the diameter of the first pressure water nozzle 121 is the same as the diameter of the second pressure water nozzle 122; the distance between two adjacent first pressure water nozzles 121 is equal to the diameter of the first pressure water nozzle 121; the distance between two adjacent second pressure water nozzles 122 is equal to the diameter of the second pressure water nozzle 122. The same diameter of the pressure water nozzles ensures that the water output of each nozzle is the same. The equal distance between two adjacent first pressure water nozzles 121 and the equal distance between two adjacent second pressure water nozzles 122 ensure that the force received by each nozzle per unit area during spraying is the same, thereby enhancing the cutting force and cutting density.

[0026] like Figure 2 As shown, in some embodiments, the spacing between two adjacent first pressure water nozzles 121 and the spacing between two adjacent second pressure water nozzles 122 are adjustable; thus, the spacing between two adjacent first pressure water nozzles 121 and two adjacent second pressure water nozzles 122 can be adjusted according to the planting distance and plant spacing of different crops, thereby treating different crop fields by changing the spacing between the pressure water nozzles.

[0027] like Figure 1As shown, in some embodiments, the pressurized water supply device includes: a water tank 13, mounted on a frame 10, for holding water; a pressure vessel, mounted on the frame 10, for holding compressed air; a water-air mixer, mounted on the frame 10, which is connected to both the water tank 13 and the pressure vessel to generate pressurized water; the water-air mixer is also connected to each pressurized water nozzle 12; a first one-way valve is provided on the connecting pipe between the water-air mixer and the water tank 13 to prevent pressurized water in the water-air mixer from flowing back into the water tank 13; a second one-way valve is provided on the connecting pipe between the water-air mixer and the pressure vessel to prevent pressurized water in the water-air mixer from flowing back into the pressure vessel; a pressure valve is provided on the pipe connecting the water-air mixer and each pressurized water nozzle 12; when the pressure of the pressurized water in the water-air mixer exceeds a certain pressure threshold, the pressure valve opens, and the pressurized water enters the pressurized water nozzle 12 and is ejected through the pressurized water nozzle 12.

[0028] like Figure 2-4 As shown, in some embodiments, a cleaning nozzle 14 is mounted on a support plate, connected to a pressure vessel, and corresponds to the pressure water jet end of a pressure water nozzle 12. The pressure nozzle 14 is used to clean the pressure water jet end of the pressure water nozzle 12 using pressurized air. The pressure vessel provides the cleaning nozzle 14 with gas at a certain pressure according to the usage requirements of the site environment. Then, the high-speed airflow of compressed air blows away fine dust, debris, and other difficult-to-remove stains from the pressure water jet end in one go. Furthermore, the use of compressed air does not generate secondary pollution, thereby improving cleaning efficiency.

[0029] like Figure 2-4 As shown, in some embodiments, a camera 15 is provided on the support plate to capture images of plants in front of the frame 10 in the direction of movement. An image recognition module, connected to the camera 15, is used to recognize the plant images captured by the camera 15 to identify whether the plants in front of the frame 10 in the direction of movement are weeds or crops. The image recognition module is also connected to a pressurized water supply device, which sends a spray control signal to the pressurized water supply device when it is identified that the plants in front of the frame 10 in the direction of movement are weeds. The pressurized water supply device supplies pressurized water to the pressurized water nozzle 12 according to the spray control signal, so that the pressurized water nozzle 12 uses pressurized water to cut the weeds with a water jet. In this way, the camera 15 records the image of the plants in front, and then the image recognition module connected to the camera 15 identifies the plants. After analysis and judgment, it is determined that the plants in front are weeds, and then a spray control signal is sent to the pressurized water supply device connected to the image recognition module to issue a clearing command. Then, the pressurized water supply device is controlled to supply pressurized water to the pressurized water nozzle 12, so that the pressurized water nozzle 12 uses pressurized water to cut the weeds with a water jet, thus performing a weed clearing operation.

[0030] like Figure 2-4As shown, in some embodiments, a fill light 16 is also provided on the support plate; the fill light 16 is positioned close to the camera 15; in this way, in the case of insufficient light, the fill light 16 can provide additional illumination to assist the camera 15 in capturing a clearer image, reducing image noise, thereby improving the brightness of the scene, making the results captured by the camera 15 clearer, and avoiding recognition errors.

[0031] like Figure 4 As shown, in some embodiments, glass plates are installed in both the direction of the light illumination of the fill light 16 and the direction of the lens of the camera 15. In this way, the glass plates on the surface of the camera 15 and the fill light 16 protect the equipment from being easily damaged by external forces and prevent pollutants from the external environment from entering. At the same time, only the outer surface of the glass plate needs to be rinsed during cleaning, which makes it convenient for users to clean and maintain it.
