摘要

根据我国目前的农业发展前景，本身是一个农业大国，差不多有十八亿亩的农田面积。对于农田施肥这一方面还有很大改进的地方，目前大部分农田施肥都是依靠人工，工作效率低，而且撒化肥分布不均匀等情况。所以针对这一情况，结合本文设计的农田施肥旋翼飞行机器人，最主要的是能够代替人工劳动力，大大地提高农田施肥的效率。
根据本文设计的农用无人机，考虑到施肥这一主要关键词，本次所设计的是多旋翼施肥无人机，对于飞行机器人的旋翼支架、着落架、化肥箱和螺旋桨等部件进行更深入的探索，参考市场上已经出现的多旋翼无人机作出改进，结合本次设计题目的实际情况进一步优化。
本文所设计的要求包括旋翼支架结构、化肥箱在飞行机器人的设计位置和撒化肥的机构等，在本次论文中有明确的说明，并给出CAD各部件的零件图和飞行机器人的模型装配图，实现了多转子飞行机器人的效率、标准化和实际应用。

Abstract

According to the current agricultural development prospect in China,Our country is a big agricultural country, China has about 1.8 billion mu of farmland area.There is a lot of improvement in the field of fertilization in the field,At present, most farmland fertilization relies on labor, low efficiency, and uneven distribution of fertilizer.Therefore, in view of this situation, combined with my design of farmland fertilization rotor flying robot, the most important is to be able to replace the artificial labor force, and greatly improve the efficiency of farmland fertilization.
According to the agricultural drone I designed, taking into account the main keyword of fertilization,This time I designed a multi-rotor fertilization uav.More in-depth exploration of the rotor support of the flying robot, the falling frame, the fertilizer box and the propeller, etc.The multi-rotor uav has been improved in reference market, and the actual situation of this design topic is further optimized.
The requirements I have designed include the rotor support structure, the design position of the fertilizer box in the flying robot, and the chemical fertilizer mechanism, etc.In this paper, there are clear instructions, and the assembly drawing of the parts drawing and flying robot of the CAD parts is given.The efficiency, standardization and practical application of multi-rotor flying robot are realized.
