Description

Automatic scanning multifunctional spraying machine for greening

Technical Field

The invention relates to the technical field of greening centrifugal air-assisted automatic induction target (or remote control) pesticide spraying devices, in particular to a greening automatic scanning multifunctional sprayer.

Background

A stretcher type sprayer or an air-assisted sprayer used for road greening currently is provided with a hydraulic adjustable spray gun with the spray width of about 0.5m, and a single high-spraying air-assisted spray head or a wide-width air-assisted spray head with fixed spray width is adopted in the air-assisted spray head with fixed spray width, except for the wide-width air-assisted spray head with fixed spray width, other machines or spray heads are divided into a heavy spray area, a leakage spray area and a single spray area by adopting a Z-shaped swinging type spraying method, and the three parts are shown in attached figure 1. 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 on the target area of unit area, see attached figure 2, the waste phenomenon that the reciprocating swinging spraying method wants to spray the target once again when the target is required to be sprayed completely (Xuyuan chapter. Z-shaped swinging spraying method target area coverage analysis [ J ], Chinese plant protection guide journal, 2021, 41 (6): 73-77.) exists, the unavoidable missed spraying area (L) in the actual spraying operation becomes the 'bridge field' of plant diseases and insect pests, and when the disease center or the part where the pests are aggregated is just the missed spraying area (L), the survived plant diseases and insect pests can be diffused and spread immediately and the pest diseases and insect pests are abandoned.

The conventional road greening air-assisted sprayer 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 implement pesticide spraying aiming at landscape characters with different heights, sizes and shapes of traffic road greening in real time, does not meet the requirements of combining agricultural machinery, forest industry and operation manpower in China and using ecological environment protection and accurate high-efficiency pesticide application in pesticide reduction, 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 and damaged road greening landscape, and cannot meet the requirements of the current ecological highway, such as loading and unloading of a bearing vehicle, design of air-assisted pesticide spraying components and principle, The requirements of green roads, the structure and the spraying method of the green roads are difficult to realize the target requirements of pesticide reduction and synergism and 'carbon peak reaching and carbon neutralization' proposed by the nation.
