The invention relates to the technical field of agricultural planting, in particular to a plant protection helicopter pressure type pesticide spraying structure which comprises a helicopter body, supporting rods are fixedly installed at the four corners of the helicopter body, wings are rotationally connected to the outer edges of the supporting rods, and supporting legs are fixedly installed on the left side and the right side of the lower end face of the helicopter body. A storage box is fixedly installed on the front side of the lower end face of the helicopter body, and a hydraulic lifter is arranged on the rear side of the storage box. The jacking block can descend by driving the hydraulic lifter, and the jacking block is rotationally connected with the connecting pieces at the upper ends of the two sets of racks through the connecting rods, so that when the jacking block descends, the racks can be pushed by the connecting rods to move towards the outer side in the sliding rails, and the jacking block is lifted; when the rack moves outwards, the rack is meshed with a gear on the rotating shaft, so that the rotating shaft rotates, and the rotating shaft rotates to carry the supporting plate to deflect, so that the supporting plate in a vertical state rotates to a horizontal state.
本发明涉及农业种植技术领域,具体为一种植保直升机压力式喷药结构,包括直升机主体,直升机主体的四角均固定安装有支撑杆,支撑杆的外边缘处转动连接与机翼,直升机主体的下端面左侧与右侧均固定安装有支撑腿,直升机主体的下端面前侧固定安装有存储箱,存储箱的后侧设置有液压升降器。本发明可以通过驱动液压升降器,使顶块进行下降,而顶块与两组齿条上端的连接件之间通过连杆进行转动连接,因此当顶块下降的时候,则会通过连杆推动齿条在滑轨的内部向外侧位移,齿条向外侧位移的时候则会与通过与转轴上的齿轮的啮合作用,使转轴进行转动,转轴转动会携带支撑板进行偏转,使得垂直状态下的支撑板转动至水平状态。
