Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and relates to a wind-transported vineyard pesticide sprayer. Background Art

[0002] When planting grapes on a large scale, large-scale pesticide spraying machines are needed to spray drugs on grape trees. The pesticide spraying machine generally includes a traveling mechanism and a pesticide spraying mechanism. The traveling mechanism carries the pesticide spraying mechanism to move, and the pesticide spraying mechanism transports the liquid in the medicine box to the spraying mechanism for spraying. In view of the characteristics of grape planting, a pesticide spraying machine with a special structure is required. The row spacing of grape racks for planting grapes is generally large, so the pesticide spraying machine needs a longer spray rod. In addition, when spraying drugs on grape trees, both the left and right sides and the top need to be sprayed.
