BOOM SPRAYER, AND BOOM-ROCKING SUPPORT MECHANISM OF BOOM SPRAYER

摘要

PROBLEM TO BE SOLVED: To enable working by approaching the tip end of a boom to the surface of a field in liquid agent-spraying work with a boom sprayer, by reducing the sway of the tip end of the boom even in the case of performing faster working by using a longer boom.;SOLUTION: A boom-rocking support mechanism (4) includes an elongating and contracting cylinder (40) one end of which is pivoted at a central machine body (2A) side and another end of which is pivoted at the boom (3) side, and the elongating and contracting cylinder has a vibration-damping means capable of flexibly bending the boom and the axial supporting part (30) of the central machine body against the vibration of the central machine body at a high acceleration in a state of fixing and supporting the boom at the central machine body, and also imparting a resistance according to a returning speed against flexible return to the bending.;COPYRIGHT: (C)2010,JPO&INPIT
