They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0041] See also Figures 1 to 6 The utility model proposes a weed identification and spraying device, comprising a mobile platform 1, a spraying mechanism 2, an adjustment mechanism 3, a lifting mechanism 4, an identification mechanism 5 and a control terminal 6; the mobile platform 1 is composed of a body structure consisting of a base plate and wheels on outriggers, two pairs of outriggers are provided in parallel on the lower surface of the base plate, and wheels are installed at the bottom end of each outrigger, and the two wheels located at the rear end of the moving direction of the mobile platform 1 are connected to drive motors, and the two drive motors work synchronously to drive the wheels to rotate, so that the mobile platform moves.

[0042] like Figures 1 to 4As shown, the spraying mechanism 2 includes a medicine storage box 21, a medicine spraying pump 22, a medicine spraying pump motor 23, a nozzle 24 and an infusion pipe 25. The medicine storage box 21 is installed on the upper surface of the base plate and close to the rear end of the base plate. The top of the medicine storage box 21 is provided with a medicine inlet 211 connected to the interior of the medicine storage box 21, and a sealing cover 212 is provided above the medicine inlet 211. The sealing cover 212 can be opened to replenish the medicine from the medicine inlet 211. Eight medicine discharge ports 213 are distributed at the rear end of the medicine storage box 21, and the medicine discharge ports 213 are connected to the interior of the medicine storage box 21; there are 8 medicine spraying pumps 22, each of which is controlled by a medicine spraying pump motor 23, and a nozzle 24 is installed under each medicine spraying pump 22. Each medicine spraying pump 22 is movably installed on the slide rail 32 through a slider 33, and each medicine spraying pump 22 is connected to the medicine discharge port 213 of the medicine storage box 21 one by one through an infusion pipe 25, and the infusion pipe 25 is a hose.

[0043] By energizing and starting the spray pump motor 23 , the herbicide is pumped out of the medicine storage tank 21 by the spray pump 22 and sprayed through the nozzle 24 .

[0044] like Figure 3 and Figure 4 As shown, the adjustment mechanism 3 includes a mounting plate 31, a slide rail 32, a slider 33 and an adjusting bolt 34. The mounting plate 31 is arranged at the rear end of the mobile platform 1 through a lifting mechanism 4 installed on the lower surface of the rear end of the base plate. The upper surface of the mounting plate 31 is connected to one end of the bottom wall of the housing 41 with two connecting plates 47 passing through. The slide rail 32 is fixedly mounted on the edge of the upper surface of the mounting plate 31 near the rear end, and the slide rail 32 is relatively horizontal to the mounting plate 31. The slider 33 is an inverted U-shape, and the number of the sliders 33 matches the number of the spray pumps 22, which is 8. The cam 33 is fixed to the rear of the slide 32 so that the slide 33 is in a position where it can move freely, and the cam 33 is fixed to the rear of the slide 32 so that the slide 33 can move freely.

[0045] Before starting work, the position of each slider 33 can be adjusted by the ridge spacing, so that the nozzle 24 below the spray pump 22 connected to the slider 33 can accurately spray the pesticide on the weeds, thereby improving the weed control efficiency.

[0046] like Figure 1 and Figure 5As shown, the lifting mechanism 4 includes a shell 41, a dual-axis motor 42, a threaded rod 43, a threaded block 44, a connecting rod 45, a movable plate 46 and a connecting plate 47; the top of the shell 41 is fixedly mounted on the lower surface of the rear end of the base plate; the dual-axis motor 42 is fixedly mounted at the upper position inside the shell 41, and the output ends on both sides of the dual-axis motor 42 are fixedly mounted with threaded rods 43, and the ends of the two threaded rods 43 away from the dual-axis motor 42 are rotatably connected to the inner walls on both sides of the shell 41; the movable plate 46 is arranged inside the shell 41 and located below the threaded rods; the outer surfaces of the two threaded rods 43 are threadedly connected to the threaded blocks 44, and the lower surfaces of the two threaded blocks 44 are hingedly mounted with connecting rods 45, and the other ends of the two connecting rods 45 are hinged to the upper surface of the movable plate 46; the lower surface of the movable plate 46 is relatively arranged by two connecting plates 47, and the ends of the two connecting plates 47 away from the movable plate 46 pass through the bottom wall of the shell 41 and are connected to the mounting plate 31.

[0047] The output ends of the dual-axis motor 42 drive the two threaded rods 43 to rotate, so that the threaded block 44 moves on the threaded rod 43, and then the movable plate 46 is driven up and down by the connecting rod 45. The distance between the nozzle 24 and the weeds can be adjusted to adapt to weeds at different growth stages, so that almost all of the herbicide sprayed by the nozzle 24 is sprayed on the weeds, so that the weeds can be removed, thereby improving the weed control efficiency.

[0048] like Figure 1 and Figure 2 As shown, the identification mechanism 5 includes a camera 51 and an identification terminal 52. The camera 51 is detachably mounted below the front end of the base plate via a mounting bracket 53. The identification terminal 52 is fixedly mounted on the upper surface of the front end of the base plate, and the camera 51 is electrically connected to the identification terminal 52. The land image data collected by the camera 51 is transmitted to the identification terminal 52. The identification terminal 52 processes the land image data and accurately analyzes the weeds. The analyzed data is then transmitted to the control terminal 6, which controls the operation of the spray pump motor 23.

[0049] like Figure 1 As shown, the control terminal 6 is fixedly mounted on the upper surface of the base plate. The control terminal 3 is respectively connected to the identification terminal 52, each spray pump motor 23 and the dual-axis motor 42. The identification terminal 52 processes the land image data and accurately analyzes the height of the weeds. The analyzed data is then transmitted to the control terminal 6. The control terminal 6 can control the dual-axis motor 42 to operate, thereby adjusting the height of the mounting plate 31 so that almost all the herbicide sprayed by the nozzle 24 falls on the weeds, thereby being able to adapt to weeds at different growth stages.

[0050] Furthermore, in this embodiment, a pipe fixing part 7 is provided on the upper surface of the bottom plate at the rear end of the medicine storage box 21, and eight through holes 71 are opened on the pipe fixing part 7. The number of the through holes 71 is the same as the number of the medicine discharge port 213. When the medicine discharge port 213 is connected to the spray pump 22 through the infusion tube 25, one end of the infusion tube 25 is first connected to the medicine discharge port 213, and the other end is connected to the spray pump 22 through the corresponding through hole 71. At this time, multiple infusion tubes 25 can be neatly arranged on the bottom plate to prevent multiple infusion tubes 25 from being tangled together, which is inconvenient to use.

[0051] Working principle:

[0052] Before using this device, the position of each slider 33 is adjusted according to the ridge spacing, and the adjusting bolt 34 is rotated so that the adjusting bolt 34 is away from the slide rail 32. At this time, the slider 33 is moved so that the nozzle 24 can be located directly above the weeds. Then, the adjusting bolt 34 is rotated to fix the slider 3 on the slide rail 32. When in use, the drive motor is energized to drive the mobile platform 1 to move. The camera 51 transmits the captured land image data to the identification terminal 52 during movement. The identification terminal 52 analyzes the land image data, determines the height and position of the weeds, and transmits the data to the control terminal 6. The control terminal 6 controls the dual-axis motor 42 to work, adjusts the height of the mounting plate 31, so that the nozzle 24 moves directly above the weeds, and at the same time controls the spray pump motor 23 to work, draws the herbicide from the storage box 21, and sprays the weeds with the herbicide.

[0053] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
