And the like. Among these, as for the support structure of the injection hole, two vertical spray pipes having an injection hole at the rear end of the vehicle body are provided in a pair on the right and left, or the vertical support pipe is provided with the injection hole. It is a structure that supports a horizontal spray tube. Some have a structure in which a vertical spray pipe having an injection hole is rotatable left and right to avoid uneven spray. Also, there is a type in which a hose is connected to a separately installed chemical solution tank, and the hose is wound up or unwound, and travels in a remote automatic control type. The same is true.

効率が向上するのである。The self-propelled sprayer itself can be applied to various spraying operations. However, depending on the object to be sprayed, the spraying operation is actually performed unless the support structure of the injection hole is changed in accordance with the spraying operation. Abnormal on the above. For example, when performing a spraying operation on cigarettes, simply spraying a chemical solution downward from above with a horizontal spray pipe has a problem that the chemical solution does not reach the leaves near the root because the leaves are large. In the case of spraying such crops, if a spray hole support structure is used in which spraying is performed simultaneously from above and below, work efficiency is improved.
