Description

Light remote-controlled multifunctional scanning sprayer for agriculture and forestry

Technical Field

The invention relates to a centrifugal air-assisted remote control (or automatic induction target) pesticide spraying device for agricultural and forestry plants, in particular to a light remote control agricultural and forestry multifunctional scanning sprayer.

Background

A stretcher type spraying machine or an air-assisted spraying machine used by current agricultural and forestry plants is used for carrying out efficient spraying protection, the stretcher type spraying machine or the air-assisted spraying machine is provided with a hydraulic adjustable spraying gun with the spraying width of about 0.5m, the air-assisted spraying machine adopts a single high-spraying air-assisted spraying head or a wide air-assisted spraying head with fixed spraying width, except the wide air-assisted spraying head with fixed spraying width, other machines or spraying heads adopt a Z-shaped swinging spraying method to divide a target area into a heavy spraying area, a leaking spraying area and a single spraying area, and the attached drawing 1 shows that the spraying area is a single spraying area. The single spray area (code D) of the swing spray method in FIG. 1 is a correct and reasonable spray area, and the heavy spray (code C) and the missed spray (code L) are problems which are difficult to avoid by the technology: in order to ensure that the target area cannot be missed, the Z-shaped swinging spraying method spray head has to spray double target area at the target area of unit area, see the attached figure 2, and has the technical defects and waste phenomena that the ' reciprocating swinging spraying method wants to spray the target once again when the target is required to be totally sprayed ' (Xuyuan chapter, Z-shaped swinging spraying method target area coverage analysis [ J ], Chinese plant protection guide, 2021, 41 (6): 73-77.), the unavoidable missed spraying area (L) in the actual spraying operation becomes the ' bridge field ' of plant diseases and insect pests, when the disease center or the rotten part of the pest is just the missed spraying area (L), the survived plant diseases and insect pests are diffused and spread immediately and then abandoned, the ' catching and releasing operations ' tiger returning to the mountain ' caused by the technical defects lead to the vicious circle of plant protection work such as insect resistance, environmental pollution, regeneration rampant and the like, therefore, the research and popularization of the performances of key operation parts such as a spray head of the pesticide applying machine are provided, the agricultural mechanization is simplified, the efficiency is improved, and the breakthrough is accelerated.

The prior agricultural and forestry pesticide spraying machines have the advantages of low work efficiency, thick fog drops, serious waste and pollution of pesticide liquid, lower coverage rate and attachment rate of the pesticide liquid, single structure and function, and no spray head with 5 spraying functions of simultaneously standard air feeding type and hydraulic type in similar agricultural and forestry plant agricultural and forestry pesticide spraying machines on the market. The conventional air-assisted sprayer for the agricultural and forestry plants mainly generates electricity through a high-power generator set and then respectively supplies energy to and drives a motor matching liquid medicine pump and an electric axial flow fan to realize remote control type liquid medicine high-pressure atomization and air-assisted spraying, is advanced in principle, but low in energy utilization rate, cannot carry out pesticide spraying on garden characters with different heights, sizes and shapes of urban agricultural and forestry plants in real time, does not meet the requirements of combining agricultural machinery, agricultural technology and operation manpower and using ecological environmental protection and accurate high-efficiency pesticide spraying in pesticide reduction in China, generates the problems of target heavy spraying and missed spraying, causes environmental pollution and great waste of water sources, pesticides and energy, has poor prevention and control effect, is damaged in agricultural and forestry plant landscape or yield, and is used for loading and unloading of a bearing vehicle and designing an air-assisted pesticide spraying component of the conventional air-assisted sprayer for the agricultural and forestry plants, The principle can not meet the requirements of the current forest city and ecological society, and the structure and the pesticide spraying method of the pesticide spraying device are difficult to realize the target requirement of pesticide reduction and efficiency improvement proposed by the country.
