[0003] 1. The weeds on the shoulder grow in clusters, causing poor rainwater drainage, rainwater infiltration, and "bubble shoulder" safety hazards.

[0004] 2. The weeds dry up in autumn, posing a fire safety hazard.

[0005] 3. The weeds grow in clusters on the shoulder, making it slippery in the rainy season, and the track patrol workers and maintenance workers are prone to slipping and falling, posing a safety hazard.

Moreover, since the device requires manual opening and closing of the valve, it is easy to forget to open or close the valve, resulting in uneven spraying or liquid leakage. At the same time, the driver in the front cab often cannot immediately determine the amount of pesticide in the tank while driving, often continuing to drive the vehicle forward even when the pesticide is running out, causing missed spraying.

[0012] In addition, the device has no stirring in the pesticide tank, making it difficult to mix the pesticide evenly. The pesticide will adhere to the inner wall of the tank, causing pesticide residue and deviation in the concentration of the pesticide. SUMMARY
