The invention relates to the technical field of undercarriages, and discloses a pesticide spraying helicopter undercarriage which comprises an undercarriage body installed at the bottom of a helicopter body, the undercarriage body comprises a fixing rod installed at the bottom of the helicopter body, and a landing plate is arranged on the inclined lower portion of the helicopter body. The landing plate is fixedly connected with the fixing rod through a connecting rod, a worm wheel is installed on the fixing rod, a worm is in transmission engagement with the worm wheel, and the worm is driven by a motor installed at the bottom of the helicopter body to rotate. According to the undercarriage, a worm and gear structure is utilized, the undercarriage is driven by a motor to be rotationally unfolded or folded and stored, the undercarriage enters a folded and stored state during flight, the protruding face of a helicopter is reduced, the risk that the helicopter is hooked and wound by branch wires and the like during flight is reduced, the undercarriage is unfolded during landing, the landing supporting requirement of the helicopter is met, and use is flexible and convenient; and the operation flight safety of the unmanned aerial vehicle in the agricultural field is greatly ensured.

    本发明涉及起落架技术领域,且公开了一种农药喷洒直升机用起落架,包括于直升机本体底部安装的起落架本体,所述起落架本体包括于直升机本体底部安装的固定杆,直升机本体斜下方设有落地板,落地板与固定杆之间通过连接杆连接固定,固定杆上安装有蜗轮,蜗轮上传动啮合有蜗杆,蜗杆由直升机本体底部安装的电机驱动转动。该起落架,通过利用蜗轮蜗杆结构由电机驱动起落架进行旋转展开或折叠收纳,飞行时进入折叠收纳状态,减少了直升机的突出面,进而降低其飞行时被树枝电线等钩缠的风险,降落时展开,满足其降落支撑需求,使用灵活方便,大大保障了农业领域无人机的作业飞行安全。
