Throwing disc, spreader and unmanned aerial vehicle

The embodiment of the utility model provides a throwing disc, a spreader and an unmanned aerial vehicle, and relates to the technical field of spreading. The throwing disc is suitable for the spreader and comprises a mounting main body and a plurality of blades, the mounting main body is provided with a swing center, the blades are arranged on the mounting main body, and when the throwing disc swings around the swing center in a reciprocating mode, the blades beat materials so as to spread the materials out. Due to the fact that the throwing disc spreader can throw out the materials in the left-right swinging direction, the spreading width of the materials is larger, the spreader can spread the materials only through swinging of the throwing disc, two side-by-side spreading assemblies do not need to be arranged, and cost is reduced. 本实用新型的实施例提供了一种甩盘、撒播器及无人机，涉及播撒技术领域。该甩盘适用于撒播器，甩盘包括安装主体和多个叶片，安装主体具有摆动中心，多个叶片设置在安装主体，其中，甩盘在绕摆动中心往复摆动时，叶片拍打物料以将物料撒播出去。由于甩盘撒播器能够将物料从左右摆动的方向上甩出，物料的播幅更大，撒播器只需要通过甩盘的摆动就可以实现物料的撒播，无需设置两个并排的撒
