Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to an adjustable forestry sprayer. Background Art

[0002] Forestry refers to the production department that protects the ecological environment, maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forest trees to play a protective role. It is an important part of the national economy. Protecting forest resources and improving the ecological environment are the main goals of ecological state construction and an important part of forestry construction. In order to protect trees, forestry workers will use fertilization equipment such as sprayers to fertilize or control pests on trees, etc.

[0003] When the current sprayers are in use, most of them are driven by trailers. The water storage tank and the nozzle are mounted on a driving vehicle such as a tractor, or manually controlled. When the trailer drives the spray pipe to move, in order to conveniently adapt to the spraying height required by different plants, most nozzles can be adjusted in height, but the spraying width on both sides of the trailer cannot be adjusted, so that the spraying area on one side can be adjusted, and the adjustment direction is relatively single.
