DISCHARGE OUTLET SWITCHING DEVICE FOR CEMENT MILK IN EXCAVATOR

摘要

PROBLEM TO BE SOLVED: To provide a cement milk discharge outlet switching device in an excavator capable of creating a high reliability as well as flowing a large amount of cement milk at the same time. SOLUTION: In a cement milk discharge outlet switching device 5 in an excavator for switching the cement milk discharge outlet built between a head 1 and a rod 2 in the excavator equipped with an excavating wing 3 and a stirring wing 4 to either a bottom discharge outlet 6 or side discharge outlet 7, the cement milk discharge switching device in the excavator comprises a member 8 at the inflow side connected in a mutually possible manner and a member 9 at the discharge side and a clutch mechanism for limiting the rotation range of the member 9 at the discharge side for member 8 at the inflow side, and the cement milk can be switched by switching the discharge outlet of the cement milk by utilizing difference in the mutual positions by the difference in the rotation direction transmitted to the member 9 at the discharge member from the member 8 at the inflow side.
