1, the layout of milling cutter and reasonable stress, the wearing and tearing of limit cutter are few.The transversal distance of the adjacent main milling cutter transversal in main milling cutter region is greater than the transversal distance of the adjacent limit cutter transversal in cutter region, limit; the cutter number that cutter region, limit is arranged is relatively many; give mutual protection between the cutter of each limit; avoid cutter tooth stressed excessive and cutter tooth fracture, wearing and tearing etc. occur, reduce the consumption of the cutter tooth of limit cutter.
2, limit cutter and vertical cutter connection and reasonable arrangement, the tool rest wearing and tearing of milling and planing drum and limit cutter are little.Form protection mutually between the cutter of each limit, outermost side cutter coordinates vertical cutter protection milling and planing drum not contact with milling road surface with the tool rest of limit cutter, reduces the wearing and tearing of the end face of milling and planing drum and the tool rest of limit cutter.
3, the main milling cutter of milling wheel and the point of a knife envelope of main limit cutter form a cylindrical milling cutter on the whole; again by the cooperation of auxiliary limit cutter, make to be formed between the cutter of limit to give mutual protection, while the cutter tooth wearing and tearing reducing limit cutter; guarantee that milling road surface is neat, thus improve milling efficiency and quality.
4, road-surface milling is steady.Main milling cutter is arranged along N bar helix separately from the intercept such as to press in the middle of axially to axial two ends, and the helix rotation direction of both sides is contrary, and the starting point of 2 × N bar helix divides the circumference of milling and planing drum equally, vibrates less, and milling is steady.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
