Detailed Implementation
[0022] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0023] Example: An intelligent obstacle-avoiding weeding robot, such as Figures 1-3 As shown, the device includes a movable bracket 1, intelligent wheels 2, an operation screen 3, a mounting plate 4, a fixing plate 5, a motor 6, a controller 61, a rotating rod 7, an electric push rod 8, a cutting blade 9, and a vision sensor 10. The movable bracket 1 serves as the mounting carrier for the parts. Intelligent wheels 2 are symmetrically mounted on the lower part of the movable bracket 1. The operation screen 3 is mounted on the upper part of the movable bracket 1. The mounting plate 4 is welded to the lower part of the movable bracket 1 and is located between the two intelligent wheels 2. Electric push rods 8 are symmetrically mounted on the upper side of the mounting plate 4. A rotating rod 7 is slidably connected to the mounting plate 4. The lower end of the rotating rod 7 is connected to the cutting blade 9, which is located below the movable bracket 1. A fixing plate 5 is connected between the upper ends of the two electric push rods 8. A device is mounted on the upper side of the fixing plate 5 by bolts. Motor 6, with its output shaft rotating through the fixed plate 5 and connected to the rotating rod 7 via a coupling, has a controller 61 mounted on the lower side of the movable bracket 1. The controller 61 is electrically connected to the smart wheel 2, the operation screen 3, the motor 6, and the electric push rod 8, and is located to the right of the cutting blade 9. A vision sensor 10 is mounted on the lower left side of the movable bracket 1, and is electrically connected to the controller 61. The vision sensor 10 is used to set the operation of the operation screen 3. The controller 61 controls the start of the motor 6 and the vision sensor 10. The vision sensor 10 analyzes the height of the grass in front by acquiring and processing images. After receiving the data, the controller 61 controls the start of the electric push rod 8 to drive the cutting blade 9 to move and adjust the cutting blade 9 to a suitable height. The motor 6 drives the cutting blade 9 to rotate to remove grass.
[0024] like Figure 3 As shown, it also includes a limiting plate 12. The limiting plate 12 is welded to the lower side of the movable bracket 1. The limiting plate 12 has evenly spaced limiting grooves and is located below the left intelligent wheel 2. The right side of the limiting plate 12 has an inverted L-shaped structure, with the middle part extending horizontally to the left and the left part extending to the lower left corner to facilitate smoothing weeds.
[0025] like Figures 3-4As shown, it also includes a contact plate 14 and a buffer plate 15. The buffer plate 15 is welded to the lower left side of the movable bracket 1. The front of the buffer plate 15 has a U-shaped structure and is located above the vision sensor 10. The contact plate 14 is welded to the left side of the buffer plate 15. The buffer plate 15 is made of apatite mineral and organic polymer composite material and is used to absorb impact energy.
[0026] like Figures 3-5 As shown, it also includes a protective pad 13, which is connected to the left side of the contact plate 14.
[0027] like Figure 1 and Figure 5 As shown, it also includes a smart water tank 16, a cover 17, and a drainage plate 20. The smart water tank 16 is installed on the upper right side of the movable bracket 1. The smart water tank 16 is electrically connected to the controller 61. The cover 17 is detachably installed on the smart water tank 16. The drainage plate 20 is connected to the lower left side of the movable bracket 1. The drainage plate 20 is connected to the smart water tank 16 and is located above the limit plate 12. When the controller 61 is activated, the smart water tank 16 is activated, and the water is discharged through the drainage plate 20 onto the grass to wash away the soil.
[0028] like Figure 2 As shown, it also includes a radar 19, which is mounted on the right side of the movable bracket 1 and is electrically connected to the controller 61.
[0029] When this device is needed, settings are configured via the operation screen 3. After receiving a signal, the controller 61 first controls the activation of the intelligent wheel 2. The intelligent wheel 2 rotates, causing the moving support 1 to shift. Next, the controller activates the motor 6, the vision sensor 10, and the radar 19. The vision sensor 10 can acquire, process, and analyze images of pedestrians, objects, and grass ahead. When it detects a pedestrian or object, the controller 61 receives a signal and controls the intelligent wheel 2 to change direction and continue moving around the pedestrian or object. This operation prevents the moving support 1 from colliding with pedestrians or objects. When the vision sensor 10 detects grass ahead, it can acquire and analyze the height of the grass and transmit the analysis data to the controller 61. After receiving the data, the controller 61 activates the electric push rod 8. The upper push rod of the electric push rod 8 shortens, causing the motor 6, the rotating rod 7, and the cutting blade 9 to move downwards. This operation adjusts the cutting blade 9 to a suitable height based on the analysis data from the vision sensor 10, facilitating stable subsequent weeding. The output shaft of the motor 6 rotates, causing the rotating rod 7 to rotate. The rotating rod 7 drives... The cutting blade 9 rotates to remove weeds. Radar 19 can monitor pedestrians and objects behind the blade in real time to prevent accidents during weeding. Before weeding, the limiting plate 12 contacts the grass, causing it to enter the upper limit groove. The tangled grass is smoothed out by the limiting plate 12, making it easier for the cutting blade 9 to remove it. Then, the controller 61 activates the intelligent water tank 16, which drains water through the drainage plate 20, spraying water onto the grass to wash away the dirt and prevent weeding. When soil remains on the surface of the cutting blade 9, it affects the weeding efficiency. After the weeding operation is completed, under the setting operation of the operation screen 3, the controller 61 will automatically control the shutdown of the motor 6, electric push rod 8, vision sensor 10 and the person. Finally, the controller 61 controls the smart wheel 2 to move back to the initial position and shuts off the smart wheel 2. When a pedestrian hits the moving bracket 1, the buffer plate 15 is deformed by the impact energy. Subsequently, the buffer plate 15 effectively absorbs the impact energy and quickly resets. The protective pad 13 can protect the buffer plate 15.
[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
