AGITATION HEAD OF AGITATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an agitation head of an agitation device, which can be smoothly rotated without being caught on gravel etc. even in the presence of the gravel etc. in soil, and which can be prevented from being corotated.;SOLUTION: This agitation head comprises an excavating blade body which is fixed to the leading end side of an excavating shaft of the agitation device and radially elongated from the excavating shaft, and an excavating edge group which is mounted downward on the excavating blade body at an almost regular interval. The agitation head is characterized as follows: the excavating blade group is composed of an almost arc-shaped excavating edge which is curved inward toward the excavating shaft in a front view; and an anti-corotation member, which is radially elongated from the excavating shaft in the state of being tilted at an angle for preventing corotation by holding the soil in rotation, is fixed in a position above the excavating blade body by the excavating shaft.;COPYRIGHT: (C)2006,JPO&NCIPI
