The present invention relates to a self-propelled pest control device that uses a spraying boom arranged on the left and right of the aircraft to be horizontally spread, an accumulator installed in a hydraulic drive circuit that drives a lifting cylinder that raises and lowers the spray boom is arranged in a balanced way on the traveling body, to improve driving stability. In the self-propelled control system equipped with the chemical tank (30) that is mounted on the rear side of the main frame(3) to which the left and right front wheels (6,6) and the rear wheels (7,7) are mounted, and boom frame (38) for mounting the containment boom (40) on the front side, the center boom (40a) and the left and right side booms(40b) are mounted to the boom frame (38) so as to be able to move up and down, and an elevation accumulator(11) for relieving pressure fluctuations in the elevation cylinder (39) for elevation and elevation of the boom frame (38) is provided in the front portion of the body. [과제] 본 발명은 기체의 좌우로 배치한 살포 붐을 횡으로 펴서 사용하는 자주식 방제기에 있어서, 살포 붐을 승강하는 승강 실린더를 구동하는 유압 구동 회로에 설치하는 어큐뮬레이터를 주행 차체에 균형 좋게 배치하고, 주행 안정성을 좋게 하는 것을 과제로 한다. [해결 수단] 좌우의 전륜(6, 6)과 후륜(7, 7)을 장착한 메인 프레임(3)의 후방측에 약제 탱크(30)를 탑재하고, 전방측에 방제 붐(40)을 장착하는 붐 프레임(38)을 탑재한 자주식 방제기에 있어서, 붐 프레임(38)에 센터 붐(40a)과 좌우의 사이드 붐(40b)을 승강 가능하게 장착하고, 붐 프레임(38)을 승강하는 승강 실린더(39)의 압력 변동을 완화하는 승강 어큐뮬레이터(11)를 기체의 전방부에 설치한 자주식 방제기로 한다.
