The bottom of the tank body is the same as the outer pipe and the inner pipe. An outer pipe electromagnetic valve is arranged inside the outer pipe. An inner pipe electromagnetic valve is arranged inside the inner pipe. The inner pipe is arranged inside the outer pipe. The portion over the outer pipe and the portion over the inner pipe are of a right-angled structure. An outer pipe medicine outlet is formed in the middle of each right-angled structure. An inner pipe medicine outlet is formed in the top of each right-angled structure. The branch pipe is arranged in the horizontal direction of the outer pipe. The right-angled structure is arranged at one end of the branch pipe. According to the spraying device, the inner pipe and the outer pipe are arranged and do not affect each other, underwater and overwater spraying can be effectively achieved, damage of pesticide to plants is lowered, and the survival rate is increased; meanwhile, two pesticide irrigation devices are combined into a whole, the structure is simple, the arrangement is reasonable, the manufacturing cost is low, and the spraying device has the obvious effect on large and middle planting fields.
