Described main pick comprises conical head and fixed end, described main pick is fixed on tubular base portion by pick box, described pick box comprises the triangle fixed part be welded on base portion and the cylindrical portion being provided with pick fixed end, described main pick become 40 ~ 50 degree of angles towards with the cambered surface of welding of pick box, the conical head of main pick is positioned at the top of triangle fixed part.Milling digs head when rotating, and main pick is better to the breakage effect of tunnel, road surface, irrigation canals and ditches, and pick box comprises triangle fixed part and is provided with the cylindrical portion of pick fixed end, and the dismounting of pick is convenient, and reliability of structure is better simultaneously.
Described triangle fixed part also wraps the crashproof end face being approximately perpendicular to welding cambered surface, and described conical head is positioned at the top of crashproof end face, and the major part of described conical head exceedes crashproof end face in the horizontal direction.Crashproof end face can prevent broken stone to the impact of pick box, and the pick box structure after welding is more firm.
The inclined-plane, rear end of described cylindrical portion is higher than welding cambered surface.Facilitate pick to be arranged in cylindrical portion, remove convenient simultaneously.
Described main pick towards with pick box weld cambered surface in angle of 45 degrees.
The fixed end of described main pick comprises circular shaft and afterbody, and the diameter of described afterbody is greater than the diameter of circular shaft, and the rear end of circular shaft is provided with draw-in groove, and circular shaft inserts the through hole of cylindrical portion and fixes with the circlip in draw-in groove.Dismounting on pick and pick box is convenient.
Compared with prior art, advantage of the present invention be main pick towards amplitude progressive conversion one by one in a spiral manner, the main pick of a part inside tubular base portion is towards inner side, the main pick of a part outside cartridge base toward the outer side, main pick on tubular base portion is towards multi-faceted covering, when milling digs head to basic thing fragmentation, not only can carry out fragmentation to the basic thing that milling is dug residing for a front, fragmentation can be carried out to the basic thing of support centre position and both sides simultaneously, improve the whole efficiency that milling is dug.
