Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a spraying rod mechanism for spraying with multiple degrees of freedom. Background Art

[0002] An orchard is a garden where fruit trees are planted. It is also called a fruit orchard. There are many types of fruit tree production bases, such as professional orchards, orchards operated by fruit farmers, and courtyard orchards. Pesticide spraying is the most critical part of orchard planting. The effect of pesticide spraying directly affects the effect of pest control, which directly affects the yield and quality of fruits. When spraying, the pesticide must be attached to all branches and leaves of the fruit tree to achieve the best prevention and control effect. However, due to the large planting area, the previous method of spraying pesticides by manpower is no longer applicable. With the development of science and technology, many operating methods that replace manpower with machinery have emerged. One of the current methods is to use an unmanned orchard pesticide sprayer to spray pesticides. Unmanned orchard pesticide sprayers generally use spray bars to spray pesticides, but the existing spray bar mechanism has a simple structure, cannot adjust the spraying position according to needs, and cannot spray pesticides on fruit trees of different heights, which is less practical.
