GUARD STRUCTURE OF WORKING MACHINE FOR GROUND

摘要

PURPOSE:To prevent the backward falling of a working machine during the operation period as well as secure safety during non-operation period by a method in which a vertical shaft tillage implement is provided to the rear of a traveling vehicle in a vertically rocking manner, and a guard to surround the implement of horizontal attitude is projectionally provided to the implement. CONSTITUTION:A vertical shaft tillage implement 10 vertically rocking between an operating position for underground tilling or excavating operation and a holding position for non-operating attitude above the ground's surface is provided to the rear of a traveling vehicular body 1. A guard 24 is provided projectionally to the rear of the vehicular body 1 to surround the implement 10 held in non-operating position. The implement 10 can thus be protected in its holding position and can be prevented from backward falling when being moved from operating to holding positions.
