Abstract
PURPOSE: To make it possible to simply and easily push out horizontally bucket of construction machine having loading shovel and the like without impairing single operations of boom, arm, and bucket of the machine by additionally arranging change-over valve in hydraulic system.
CONSTITUTION: Boom operating cylinder 4 and arm operating cylinder 6 for loading shovel have their respective change-over valves 16 and 19 connected through pipes 17, 17' and 20, 20' respectively. Branch pipes 22, 22' and 23, 23' branched respectively from pipes 17, 17' and 20, 20' are all connected to bucket push-out change- over valve 24. The additionally arranged change-over valve 24 is functional to connected boom operating cylinder 4 and arm operating clinder 6 not only in series but also in such a way that when piston rod of cylinder 4 is extended, piston rod of cylinder 6 is extracted, and vice versa, therefore, by merely operating the change- over valve 24, bucket 7 of the machine can be horizontally pushed out without simultaneously moving boom 3 and arm 5 which are usully moved simultaneously with bucket 7 in prior art.
