Abstract
The invention discloses a milling-planing rotor. The milling-planing rotor comprises a cylinder body, wherein a rotor reducer mounting flange is arranged on the inner wall of the cylinder body, a plurality of cutter subassemblies are arranged on the outer wall of the cylinder body and are distributed in two groups of spiral lines along inverse directions from the middle part of the cylinder body to the two ends, and a knockout plate mounting flange is also arranged at the initial point positions of the spiral lines at the middle part of the cylinder body and is provided with a knockout plate. Due to the adoption of the milling-planing rotor, the problems that an existing milling-planing rotor is large in cutting resistance and inconvenient in material slag collection are solved; as the spiral lines are connected end to end smoothly, the resistance of the milling-planing rotor when a pavement is cut is weakened, the material collection ratio and the exhausted ratio are also greatly increased when the milling efficiency is ensured, the service life of each cutter is also prolonged, the later maintenance cost is reduced, and the changing difficulties of a cutter holder and the knockout plate are also greatly weakened.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
The structure of a kind of milling rotor provided by the invention as shown in Figure 1, comprise cylindrical shell 1, on the inwall of cylindrical shell 1, be provided with rotor reductor mounting flange 2, on the outer wall of cylindrical shell 1, be provided with multiple set of knives components 3, multiple set of knives components 3 are two groups of spiral line types of opposite direction and arrange along centre to the two ends of cylindrical shell 1, the centre of cylindrical shell 1 is positioned at helix initial point position place and is also provided with knockout plate mounting flange 4, is provided with knockout plate 5 on knockout plate mounting flange 4.
As shown in Figure 2, set of knives component 3 places of position, end, the two ends of cylindrical shell 1 are provided with protection knife combination 6.
As shown in Figures 3 and 4, set of knives component 3 comprises the tool rest cushion block 31 being welded on cylindrical shell 1, is provided with tool rest 32 on tool rest cushion block 31, is sheathed with tooth cover 33 on tool rest 32, in tooth cover 33, is sheathed with cutter head 34.
The external surface of tooth cover 33 has the tapering of 7 °～10 °.
The axis projection of cutter head 34 overlaps with the helix at its place.
Set of knives component 3 arrange composition every group of helix be provided with three.
Milling rotor of the present invention is connected with rotor reductor by rotor reductor mounting flange 2, be arranged on milling machine by rotor rack, in the time that machine is worked, the rotation of milling rotor high-speed, the epitrochanterian cutter head of milling starts milling road surface, and material slag after milling focuses on by the high speed rotating of helix on the knockout plate 5 in cylindrical shell 1 centre position, the material slag that the knockout plate 5 of rotation gets off milling gathers on material-conveying belt, then by material-conveying belt, material slag is transferred on engineering truck.And the protection knife combination 6 of the end setting of milling two ends of rotor, helix is used for ensureing the regularity of milling target edges.
The direction of rotation of existing cutter head and helix is inconsistent, in the time of cutter head rotation milling road surface because thereby helix direction of rotation and cutter head milling are subject to the inconsistent milling resistance that causes of force direction larger, cause cutter head shorter application life, and material is also easily leaked in helix rotation while gathering materials.And in the present invention because set of knives component 3 and helix rotation trend is consistent, being projected on helix of cutter head 34, in the time of cutter head 34 milling road surface due to be subject to force direction unanimously make cutter head rotation even wearing and milling effect better, overcome the cutting resistance that has angle between existing cutter head and helix and cause large, and be unfavorable for the problem of expecting that slag is collected.
The present invention overlaps 33 by conical tooth and coordinates with tool rest 32, cutter head 34 is at work by making conical tooth cover 33 can closely cooperate with tool rest 32 to the reaction force of milling object, the tooth cover that has overcome prior art existence coordinates easily loosening problem with tool rest, and the tooth of taper cover 33 is greatly more easily pounded out and changed by equipment such as crooked chisels above due to below little.
Exemplary, a kind of milling rotor of the present invention also can be applied on the large-scale milling devices such as coal-cutting machinery equipment.
By the way, to have solved cutting resistance that existing milling rotor exists large and be unfavorable for the shortcoming of expecting that slag is collected for a kind of milling rotor of the present invention.A kind of milling rotor helical-screw line of the present invention is end to end, smooth, resistance while having reduced cutting road surface, in ensureing milling effect, also greatly improve and gathered materials rate and adopt most rate, extend cutter life simultaneously, reduced later maintenance cost, and also greatly reduced the replacing difficulty of tool rest and knockout plate.
