Technical Field

[0001] The invention relates to the technical field of fertilizing and spraying equipment, and in particular to a comprehensive gardening and greening maintenance vehicle. Background Art

[0002] In the cultivation and care of garden plants, not only should fertilizers be applied regularly to provide the necessary nutrients for trees and green plants, but pesticides should also be applied to prevent the occurrence of diseases and insect pests. Traditional fertilization and pesticide application adopts manual spraying, which is time-consuming and laborious, with low operation efficiency. In addition, some trees and green plants can only reach the root system directly through deep root fertilization or pesticide application, preventing fertilizer or pesticide from volatilizing or being washed away by rain, and reducing environmental pollution.

The fertilizer box and the power system used in conjunction with it are placed on the vehicle body, and the discharge port of the fertilizer box is connected to the injection tube through a connecting hose. Its disadvantages are that the injection tube has no auxiliary drilling and pressurization functions, the operation is laborious, the fertilization efficiency is low, and the water pipe has no telescopic function, the operating range is limited, there is no liquid stirring function, the drug power is uneven, and it cannot meet the requirements of deep root fertilization and spraying of street trees; on the other hand, the control is simple, the fertilization accuracy is not high, and there is no foliar spraying function. All parts are exposed and arranged without effective protection. They are prone to aging and damage, and cannot meet the needs of fine maintenance of garden plants for a long time. Based on this, the present invention designs a comprehensive landscaping maintenance vehicle to solve the above problems. Summary of the invention
