Vibration damping for the spray bar of an agricultural sprayer

摘要

The field sprayer (1) has a liquid container (2) and a spraying linkage (3) with two linkage units (6,7). A pendulum system (4) is connected over the spraying linkage. A lifting system (5) is connected with a frame (17), and is horizontally pivoted around axis (8,9) of the linkage units. A spring damper (11) is engaged at an arm (10) spaced at the distance from the linkage units. The two linkage units are supported against each other over the arm through an additional spring damper (15) with respect to the lifting system.
