DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1-Figure 4As shown, in this embodiment, the herbicide spraying device includes a base plate 1, a handrail 20 and a first vertical plate 5. The top of the base plate 1 is fixedly connected to a storage tank 10, the handrail 20 is fixedly connected to the top of the base plate 1, the inside of the storage tank 10 is rotatably connected to a stirring rod 19, the first vertical plate 5 is fixedly connected to the top of the base plate 1, the top of the base plate 1 is fixedly connected to a second vertical plate 9, a displacement assembly is arranged between the first vertical plate 5 and the second vertical plate 9, a first motor 2 is fixedly installed on the top of the storage tank 10, one end of the output shaft of the first motor 2 is fixedly connected to one end of the rotating shaft of the stirring rod 19, a feed pipe 11 is fixedly connected to the top of the storage tank 10, a displacement plate 8 is slidably connected between the first vertical plate 5 and the second vertical plate 9, the top of the displacement plate 8 is rotatably connected to a spray head 7, an adjustment assembly is arranged on the top of the displacement plate 8, and a hose 3 is arranged between one side of the spray head 7 and the top of the storage tank 10.

[0023] First, the device is moved to the weeding location by pushing the handrail 20, and then water and herbicide are injected into the storage tank 10 through the feed pipe 11. Then, the stirring rod 19 is driven to rotate by starting the output shaft of the first motor 2 to mix the water and herbicide in the storage tank 10. A water pump is arranged inside the storage tank 10, and then the mixed agent is sprayed out through the hose 3 through the nozzle 7. Since the spraying height needs to be adjusted for different weeds, the displacement plate 8 is driven to adjust the height by starting the displacement component, thereby driving the spraying height of the nozzle 7 to adjust. This can be suitable for weeding operations on different weeds, thereby increasing the applicability of the device. Then, when spraying, the nozzle 7 is driven to adjust the horizontal angle on the top of the displacement plate 8 by starting the adjustment component. This can accurately control the spraying position of the nozzle 7 for weeds in different directions, saving the amount of herbicide used, thereby increasing the practicality of the device.

[0024] like Figure 1-Figure 4 As shown, the displacement assembly includes a reciprocating screw 6, which is rotatably connected between the first vertical plate 5 and the bottom plate 1, and a second motor 4 is fixedly installed on the top of the first vertical plate 5. One end of the output shaft of the second motor 4 is fixedly connected to the top of the reciprocating screw 6. A threaded groove is provided on the side of the displacement plate 8 close to the first vertical plate 5 and is threadedly connected to the outer side surface of the reciprocating screw 6 through the threaded groove. The displacement assembly also includes a sliding rod 12, which is fixedly connected between the second vertical plate 9 and the bottom plate 1, and a side of the displacement plate 8 away from the reciprocating screw 6 is movably sleeved with the outer side surface of the sliding rod 12.

[0025] When adjusting the height of the nozzle 7, the output shaft of the second motor 4 is started to rotate, driving the reciprocating screw 6 to rotate between the base plate 1 and the first vertical plate 5, while driving the displacement plate 8 to move on the outside of the slide bar 12. The movement of the displacement plate 8 is guided by the slide bar 12, and then the displacement plate 8 moves to drive the nozzle 7 to adjust its height, thereby increasing the practicability of the device.

[0026] like Figure 1-Figure 4 As shown, the adjustment component includes a limit groove 16, which is opened through the surface of the displacement plate 8, and the inside of the limit groove 16 is slidably connected with a slider 15. The adjustment component also includes a cylinder 14, which is fixedly installed on the top of the displacement plate 8, and one end of the movable rod of the cylinder 14 is fixedly connected to one side of the slider 15.

A displacement groove 17 is opened on the top of the slider 15, and the outer side of the displacement rod 18 is slidably connected to the inner wall of the displacement groove 17.

[0027] When adjusting the horizontal angle of the nozzle 7, the movable rod of the cylinder 14 is started to move and drive the slider 15 to slide inside the limit groove 16, and the movement of the slider 15 is limited by the limit groove 16. Then the slider 15 moves to drive the displacement rod 18 to slide inside the displacement groove 17 and drive the connecting rod 13 to rotate. Then the connecting rod 13 is fixed to the rotating shaft of the nozzle 7, so that the nozzle 7 rotates accordingly, so that the angle of the nozzle 7 can be conveniently adjusted.

[0028] The utility model provides a herbicide spraying device, and the specific working principle is as follows: first, the handrail 20 is pushed to drive the device to move to the weeding location, and then water and herbicide are injected into the storage tank 10 through the feed pipe 11, and then the first motor 2 is started to rotate the output shaft to drive the stirring rod 19 to rotate, so as to mix the water and herbicide in the storage tank 10. The storage tank 10 is provided with a water pump, and then the mixed agent is sprayed out through the hose 3 through the nozzle 7. Since the spraying height needs to be adjusted for different weeds, at this time, the reciprocating screw 6 is driven between the bottom plate 1 and the first vertical plate 5 by starting the output shaft of the second motor 4 to rotate. The displacement plate 8 is rotated and driven to move on the outside of the slide bar 12 at the same time, and the movement of the displacement plate 8 is guided by the slide bar 12. Then the displacement plate 8 moves to drive the nozzle 7 to adjust the height. Finally, when adjusting the horizontal angle of the nozzle 7, the movable rod of the cylinder 14 is started to move and drive the slider 15 to slide inside the limiting groove 16. The movement of the slider 15 is limited by the limiting groove 16. Then the slider 15 moves and drives the displacement rod 18 to slide inside the displacement groove 17 and drives the connecting rod 13 to rotate. Then the connecting rod 13 is fixed to the rotating shaft of the nozzle 7, so that the nozzle 7 rotates accordingly, so that the angle of the nozzle 7 can be conveniently adjusted.
