Embodiment

A kind of cutter-head of machine for making furrows, as shown in Figure 1, comprises ditching knife group 1 and tool rest 2; Described ditching knife group 1 comprises bite 3, throws native cutter 4 and holder 5, and bite 3 comprises cutting toolholder 31 and cutter tip 32, throws native cutter 4 and comprises the native handle of a knife 41 of throwing and throw native cutter head 42; Described cutting toolholder 31 and the native handle of a knife 41 of throwing are same plate profile structure, and cutter tip 32 is crotch shape, as shown in Figure 2, throw the inverted-triangular that native cutter head 42 is middle part perforate, and inner side is provided with cross bar 43; Described cutting toolholder 31 is inserted in holder 5 and by bolt and is arranged on together with holder 5 on tool rest 2 with the native handle of a knife 41 of throwing; Described tool rest 2 is disc.

Described bite 3 and the native cutter 4 of throwing equidistant and alternative arrangement on tool rest 2 circumference.Described holder 5 has with cutting toolholder 31 or throws the handle of a knife installing hole that native handle of a knife 41 matches.Described cutting toolholder 31 or throw on native handle of a knife 41 has along the tapped through hole 6 of the cross-sectional direction of width.Described holder 5 is trapezoidal, and middle part has slotted hole 7.As shown in Figure 3, on tool rest 2, there is the dovetail groove 21 matching with holder 5.Dovetail groove 21 tops on described tool rest 2 communicate with tool rest 2 circumferential outer edge.On described tool rest 2, have with cutting toolholder 31 or throw the tapped blind hole 8 that the tapped through hole on native handle of a knife 41 matches.Described tool rest 2 is provided with balance weight 22.

When bite 3 is installed, be placed in tool rest 2 dovetail grooves 21 that just in time match with it being trapezoidal holder 5, cutting toolholder 31 is inserted to the handle of a knife installing hole of holder 5, tapped through hole on cutting toolholder 31 6 is aligned to the slotted hole 7 of holder 5, put screw, screw in tapped through hole 6 by slotted hole 7 successively, last precession tapped blind hole 8 is fixed on sharpener 3 on tool rest 2 by holder 5.The installation method of throwing native cutter 4 is identical with bite 3 installation methods.
