Problems solved by technology

[0005] When the UAV proposed in the above-mentioned patent sprays and kills insects on crops, it can only spray from above the crops, and the liquid medicine sprayed on the crops drips on the leaves of the crops, so as to prevent the insects hidden on the branches of the crops. However, when the crops grow luxuriantly, a small part of the liquid sprayed on the leaves of the crops drops, and when the weather is fine, the liquid on the leaves of the crops will evaporate quickly, greatly reducing the damage to the crops. bug effect
