The invention discloses a multi-rotor plant protection unmanned aerial vehicle with rotor wings distributed in a trapezoid mode, and relates to the field of multi-rotor plant protection unmanned aerial vehicles, seven pairs of rotor wings are distributed on two pairs of symmetrical rotor wing support plates and rotor wing support connecting plates in a trapezoid mode, and the rotor wings are the same in size and driven by brushless direct current motors of the same specification. Seven pesticide sprayers are correspondingly installed below the central axes of the seven pairs of rotors, and pesticide in the pesticide box is atomized and sprayed out through the seven pesticide sprayers and is sprayed to farmland in an accelerated mode through downward washing airflow of the seven pairs of rotors. According to the multi-rotor plant protection unmanned aerial vehicle, airflow interference between each pair of rotors can be reduced through special trapezoidal distribution of the rotors, more rotors can be installed on the long sides of the trapezoid, therefore, the effective spraying width of pesticide is increased, and compared with a traditional multi-rotor plant protection unmanned aerial vehicle, the multi-rotor plant protection unmanned aerial vehicle with the rotors distributed in the trapezoidal mode is better in aerodynamic performance and plant protection efficiency.

    本发明公开了一种旋翼梯形分布的多旋翼植保无人机,涉及多旋翼植保无人机领域,本发明的七副旋翼呈梯形分布在两副对称的旋翼支架板和旋翼支架连接板上,每副旋翼大小相同,并由相同规格的无刷直流电机驱动。七副旋翼的中轴线下方对应安装七具农药喷头,农药箱中的农药经七具农药喷头雾化喷出,经七副旋翼的下洗气流加速喷施至农田。本发明特殊的旋翼梯形分布可以减少每副旋翼之间的气流干扰,梯形的长边可以安装更多数量的旋翼,因此农药的有效喷施宽度变长,相比传统多旋翼植保无人机,旋翼梯形分布的多旋翼植保无人机的气动性能和植保效率更优。
