Rotor wing suspension width spraying rod spraying machine and control method thereof

Abstract

The invention discloses a rotor wing suspension width spraying rod spraying machine and a control method thereof. The spraying machine comprises a spraying machine body, a pair of polygon rollers aremounted on the spraying machine body, rotor wing width spraying rods are arranged on the polygon rollers and positioned on two sides of the spraying machine body after being unfolded, the rotor wing width spraying rods comprise motors, propellers, a plurality of rotor wing spraying rod units and a plurality of sprayers, the propellers are connected with the motors, the rotor wing spraying rod units are connected, the sprayers are arranged on the rotor wing width spraying rods, the rotor wing spraying rods are unfolded and folded by the polygon rollers, self-balancing height setting systems arearranged on the rotor wing spraying rods and used for acquiring height information to adjust and control balance of the spraying rod and the height between the spraying rod and the ground, and a maincontrol system connected with the polygon rollers, the motors and the self-balancing height setting systems is mounted on the spraying machine body. According to the spraying machine, horizontal states of the width spraying rod can be ensured in the various postures of the body, contact between the sprayer and the ground caused by long spraying rod and wide spraying swath is avoided when the bodyrotates, the rotor wings provide lifting power for width spraying rod, a complex and expanded truss structure is avoided when the spraying rod is enlarged.

Description

technical field [0001] The invention relates to the technical field of sprayers, in particular to a rotor-suspended wide-spray boom sprayer and a control method thereof. Background technique [0002] At present, the existing large and medium-sized ground power plant protection machinery mainly adopts tractor-drawn, suspended or self-propelled load-bearing methods, and the spraying methods mainly include air-driven, boom spraying and other forms. [0003] Air-driven sprayers usually use tractors or agricultural vehicles as the driving force. Through the high-speed centrifugal fan air supply system, the fog droplets are atomized and transported remotely. The range is longer and the work efficiency is higher. However, at present, the air-driven sprayer has not been widely used in rice production, mainly because in practical application, the machine still has mist droplets that are easy to drift, precise control of spraying effect is poor, and it is easy to be restricted by road...

AI Technical Summary

Problems solved by technology

However, due to the paddy field wheel welded by the steel plate of the stretching machine, there are problems such as excessive weight of the overall machine tool, large damage to the mud bottom, large field operation vibration, large pressing loss, and inconvenient field U-turn, so the application range is limited.

[0006] Manned aircraft have high operational efficiency, but there are many problems such as the need for a dedicated airport, high maintenance costs, long refilling cycles to and from the airport, and strict aviation controls.

Unmanned helicopters have the characteristics of no need for special airports, professional pilots, low maintenance costs, and less air traffic control. Secondary pollution, long-distance manual remote control operations are likely to cause visual deviation, resulting in missed spraying and heavy spraying, etc., which restrict its development.
