Spraying bar assembly for agricultural sprayer, has connecting rods with articulation points displaced on boom frame to reestablish equilibrium of ramp support so as to offer same inclination if arms are deployed in symmetrical manner

摘要

The assembly has two boom sections (3, 5) mounted articulated on both sides of a boom frame (1). A ramp support (7) is mounted on a carrier. Connecting rods (9, 11) are interposed between the frame and the support. The rods have articulation points whose height is adjustable, where the points are displaced on the frame to reestablish the equilibrium of the support so as to offer same inclination if arms are deployed in a symmetrical manner. An independent claim is also included for an agricultural sprayer comprising a spraying bar assembly.
