The inner side of the outer tube body 121 is provided with a non-powered stirring blade 122, the outer tube body 121 is connected to one end of the feed pipe 15, the other end of the feed pipe 15 is inserted in the raw material bottle 16, and the raw material bottle 16 is inserted with an air intake pipe 17. When the blade 3 rotates to mow the grass, the water in the water tank 10 is transported by the water pump 8 and sprayed out through the nozzle 14 to form a water curtain to achieve the effect of dust suppression. At the same time, the herbicide in the raw material bottle 16 is sucked into the outer tube body 121 through the feed pipe 15 under the action of the flow rate difference, and is efficiently mixed with the water flow under the action of the non-powered stirring blade 122, so as to achieve a long-term weeding effect after spraying. The non-powered stirring blade 122 has a spiral plate structure, and the number of the non-powered stirring blade 122 is multiple The two non-powered stirring blades 122 are arranged in a connected manner along the axis of the outer tube body 121, and the angle between the two adjacent non-powered stirring blades 122 is 90 degrees. Driven by the water flow, the water flow and the herbicide are blocked and guided by the non-powered stirring blades 122 to produce a vortex, thereby achieving mixing of the agent and the water body, so that the diluted herbicide can achieve a better use effect. The feed pipe 15 is arranged on the outer tube body 121 between the non-powered stirring blades 122 and the water pump 8. The water flow maintains a high speed flow before entering the non-powered stirring blades 122, so that the herbicide in the raw material bottle 16 is effectively sucked into the outer tube body 121. The air inlet pipe 17 is inserted through the bottle cap of the raw material bottle 16, and the outside air can enter the raw material bottle 16 through the air inlet pipe 17. The material bottle 16 is filled with the herbicide, so that the herbicide in the material bottle 16 is effectively sucked into the outer tube body 121. The number of the nozzles 14 is multiple and they are arranged on the left and right sides of the weeding motor 2. The nozzles 14 are fan-shaped nozzle structures. The water mist sprayed by the multiple nozzles 14 can cross over the top of the blade 3 to form a water curtain, thereby achieving an effective dust suppression effect. The water supply hose 9 is an inner-lined wire ring hose structure. The inner-lined wire ring in the water supply hose 9 can provide rigid support for the water supply hose 9 to prevent the water supply hose 9 from being deformed and flattened under the influence of negative pressure under the suction of the water pump 8, affecting the passing speed of the water flow. The water tank 10 is provided with a shoulder strap 11, and the operator can carry the water tank 10 on the back through the shoulder strap 11, which is labor-saving and convenient to carry the water tank 10.

[0034] The working principle of the present technical solution is as follows: the operator carries the water tank 10 on his back through the shoulder strap 11, and then starts the weeding motor 2 to carry out weeding. When the weeding motor 2 is running, it drives the blade 3 to rotate at high speed, thereby breaking the grass. At the same time, the operator starts the water pump 8, so that the water in the water tank 10 is sucked into the mixing pipe 12 through the water supply hose 9. When the water flows at high speed in the outer tube body 121 under the action of the flow rate difference, the herbicide in the raw material bottle 16 is sucked into the mixing pipe 15 through the feeding pipe 15. In the outer tube body 121, the mixed water flows together toward the unpowered stirring blades 122. When passing through the unpowered stirring blades 122, the mixed water flows are blocked and guided by the unpowered stirring blades 122 to generate a vortex, thereby achieving mixing of the agent and the water body, so that the diluted herbicide can achieve a better use effect, and then enters the connecting head 13, and is sprayed out from the nozzle 14 to form a water curtain, covering the top of the blade 3, thereby preventing dust from overflowing during the mowing process. When the water mist falls on the ground, it can also effectively prevent the growth of weeds.
