Problems solved by technology

[0005] However, in these existing devices and technologies, the material flow is simply adjusted, the control is not precise, the material flow is discontinuous, and the response speed is slow. At present, there is no relatively complete control system that can control the sowing according to the operating parameters of agricultural drones. Real-time precise adjustment of volume
In addition, the existing technology mainly uses the centrifugal force of the disc to throw the particles out. The seed falling area is a circular or semi-circular belt, and the seed falling is uneven in the direction perpendicular to the forward direction of the agricultural drone.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a material spreading device and method mounted on an agricultural drone. Background technique [0002] With the development of agricultural aviation and intelligent communication technology, intelligent agricultural equipment has gradually replaced traditional mechanical tools. The sowing method has undergone a transformation from manual sowing to mechanical sowing, and even to integrated operations. However, my country's terrain is complex, and the area of ​​cultivated land in non-plain areas is relatively large, especially in hilly areas and paddy fields, so it is difficult for ground walking machines to operate. In addition, it is not suitable for large-scale sowing of grass seeds and tree seeds by ground machinery in areas with severe land desertification such as wastelands, and the operation efficiency is low, and the survival rate of vegetation is not hi...
