The invention discloses a multi-rotor plant protection unmanned aerial vehicle undercarriage, and relates to the technical field of agriculture and forestry planting. The undercarriage comprises a supporting base, a hanging rod and a movable block, a first chute is formed in the top end of a top supporting column. The hanging rod is embedded into the first chute in a sliding fit mode; a first spring is installed at the top end of the hanging rod embedded in the first chute, the hanging rod is of an L-shaped rod structure and is horizontally placed, a clamping block protruding downwards is arranged at the end, stretching out of the top of the top supporting column, of the hanging rod, and a second chute of a square structure is formed in the inner side wall of the clamping block. The rotating motor drives the nut to move upwards, after the nut moves upwards, the distance between the nut and the cylindrical sleeve is gradually increased, and when a rhombus frame contracts, the area exposed in the air is reduced and the flying resistance of the unmanned aerial vehicle is reduced when the unmanned aerial vehicle takes off and is contracted and folded through the rhombus frame.

    本发明公开了一种多旋翼植保无人机起落架,涉及农林种植加工技术领域,包括承托底座、悬挂杆、活动块,所述顶支撑柱的顶端开设有第一滑槽,所述悬挂杆通过滑动配合方式嵌入于第一滑槽内,嵌入于第一滑槽内的所述悬挂杆顶端安装有第一弹簧,所述悬挂杆为L形杆结构,所述悬挂杆呈水平摆放,伸出在顶支撑柱顶部的所述悬挂杆的端部设置有向下凸起的卡块,所述卡块的内侧壁开设有方形结构的第二滑槽。本发明通过旋转电机驱动螺母向上移动,螺母向上移动后,螺母与圆柱套筒之间的距离逐渐增大,菱形架收缩时,使无人机在起飞时,通过菱形架收缩折叠后,减少暴露在空气中的面积,减小无人机飞行时的阻力。
