Automatic profile-modeling spraying device and angle adjustment method of agricultural aviation crop protection machine

Abstract

The invention belongs to the field of agricultural aviation crop protection and relates to an automatic profile-modeling spraying device and angle adjustment method of an agricultural aviation crop protection machine. The automatic profile-modeling spraying device and the angle adjustment method aim at solving the problem that crops are in gradient type inclined distribution due to biological contour characteristics of inclination of a crop crown and the terrain, and a machine body is inclined when turning, so that spraying is not conducted uniformly. By means of the automatic spray boom angle adjustment method of the aviation crop protection machine, a mathematic model with the inclination angle of the machine body equal to the reverse deflection angle of adjustment of a spray boom or with included angle between the surface of a profile-modeling crop and the ground equal to the reverse deflection angle of adjustment of the spray boom is established, and the angle of the spray boom is adjusted automatically through the model, so that the automatic profile-modeling spraying device achieves the effects of conducting profile-modeling on the contour of the crop crown and improving spraying uniformity. By detecting such factors as biological characteristics, geographical factors and machine body inclination, spray boom angle adjustment applicable to the complex environmental condition is instructed to be designed, the effects of applying less pesticide and applying pesticide better are achieved, spraying uniformity is improved, the coverage rate is raised, and the utilization rate of pesticide is raised.

Description

technical field [0001] The invention belongs to the field of agricultural aviation plant protection, in particular to an automatic profiling spraying device of an agricultural aviation plant protection machine and an angle adjustment method thereof. Background technique [0002] There are many factors that affect the uniformity of aviation spray. As far as the fixed boom of the aerial plant protection spraying machine is concerned, the uniformity of the spray is bound to be greatly affected under the following circumstances: First, the crops caused by the terrain are distributed in a "gradient" or slope (hereinafter collectively referred to as gradient) . Due to the gradient distribution of crops caused by the slope of the ground, if the angle of the spray boom of the agricultural aviation plant protection machine cannot be adjusted, it will inevitably lead to uneven distribution of fog droplets during the operation of the agricultural aviation plant protection machine. Se...

Problems solved by technology

During the spraying operation of the agricultural aviation plant protection machine, the tilt of the fuselage caused by the aircraft turning in the field is inevitable, or the tilt of the fuselage caused by improper operation by the operator often occurs. If the spray boom of the agricultural aviation plant protection machine is not adjustable, the application Drug uniformity can be greatly affected
