[Problems to be Solved by the Invention] In the control work of agricultural crops, it is necessary to spray the chemical solution evenly over the entire crop. However, as in the past, in a self-propelled sprayer that carries out control work by reciprocating traveling, in the case of a boom with both sides, the spray width is determined by the length of the boom, and there is a limit to the length of the boom. To widen the vehicle, it was necessary to make the traveling machine larger. Further, the H type and the I type are determined by the ejection pressure from each nozzle and the size of the ejection port, and the reach of the chemical solution is relatively short. Therefore, the present invention seeks to provide a self-propelled sprayer having a wide spraying width.
