Directional spraying device and directional spraying control method for plant protection plane

Abstract

The invention discloses a directional spraying device for a plant protection plane. The directional spraying device comprises a spraying frame, a telescopic connecting rod, a rotating angle motor, an angle inclination measuring instrument and a system control module. The spraying frame is arranged at the bottom of the plant protection plane and comprises nozzles arranged in parallel and upper and lower flow adjusting pieces used for adjusting the flow of the nozzles in front-back inclination of the plant protection plane. The telescopic connecting rod is arranged between the spraying frame and the plant protection plane, and the left-right inclination angle of the spraying frame is adjusted by controlling the telescoping length of the telescopic connecting rod. The rotating angle motor is arranged at one end of the spraying frame, and the spraying frame is made to rotate around the axis by controlling the rotating angle of the rotating angle motor. The angle inclination measuring instrument is arranged in the middle of the spraying frame and used for detecting the inclination direction and inclination angle of the plant protection plane. The system control module is connected with the angle inclination measuring instrument and used for recording electrical signals detected by an inertia gyroscope and controlling the telescoping length of the telescopic connecting rod and the flow of the nozzles. The invention further discloses a directional spraying control method for the plant protection plane. The spraying angle can be accurately adjusted by adjusting the flow of the nozzles.

Description

technical field [0001] The invention relates to the field of plant protection aircraft spraying, in particular to a plant protection aircraft directional spraying device, in particular to a method for controlling the plant protection aircraft directional spraying device.

[0002] From the perspective of the development of plant protection technology in the world, the use of plant protection aircraft spraying has strong adaptability to terrain and can adjust the microclimate in the field. It is one of the effective methods to realize water-saving agriculture. The main method of rodent infestation, the traditional artificial plant protection operation is more and more unsuitable for my country's urbanization construction, and the pace of the sharp decrease of the rural labor force. Since it is not restricted by geographical factors and crop growth, aerial plant protection is the development trend of agricultural plant protection. In the known technology, the plant protection aircraft all adopt the suspended plant protection spraying device, and its spraying device is fixed on the plant protection aircraft, and its spraying angle changes with the flight attitude of the plant protection aircraft. , the spraying device cannot implement directional and targeted pesticide application, which causes a large amount of drift of pesticide droplets, uneven water distribution, and low utilization rate of pesticides
