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.

Specific embodiment
With reference to specific embodiment, the present invention is described in detail.
A kind of structure of milling rotor that the present invention provides, as shown in figure 1, including cylinder 1, the inwall of cylinder 1 is provided with
Rotor reductor mounting flange 2, the outer wall of cylinder 1 is provided with multiple knife combination parts 3, multiple knife combination parts 3 are along cylinder 1
Centre to two ends be in two groups of spiral line types arrangement in opposite direction, the centre of cylinder 1 is located at helix initial point position also
It is provided with knockout plate mounting flange 4, knockout plate mounting flange 4 is provided with knockout plate 5.
As shown in Fig. 2 being provided with protection knife combination 6 at the knife combination part 3 of two ends end position of cylinder 1.
Knockout plate 5 is bolted on knockout plate flange 4.
As shown in Figures 3 and 4, knife combination part 3 includes the tool rest cushion block 31 being welded on cylinder 1, on tool rest cushion block 31
It is provided with tool rest 32, fit set 33 with teeth on tool rest 32, it is sheathed with cutter head 34 in tooth set 33.
The outer surface of tooth set 33 has 7 °～10 ° of taper.
The axis projections of cutter head 34 are overlapped with the helix that it is located.
Every group of helix of knife combination part 3 arrangement composition is provided with three.
The milling rotor of the present invention is connected with rotor reductor by rotor reductor mounting flange 2, by rotor rack
It is arranged on milling machine, when machine operation, milling rotor high-speed rotation, the cutter head on milling rotor starts milling road surface, and
Material residue after milling focuses on the knockout plate 5 in cylinder 1 centre position by the high-speed rotation of helix, the knockout plate 5 of rotation
The material residue that milling is got off gathers on material-conveying belt, then by material-conveying belt, material residue is transferred on engineering truck.And milling rotor
Two ends, the protection knife combination 6 of the end setting of helix are used for ensureing the regularity of milling target edges.
Existing cutter head is inconsistent with the direction of rotation of helix, when cutter head rotation milling road surface due to helix rotation
Direction is inconsistent with cutter head milling Impact direction to lead to cutter head service life shorter thus leading to milling temperature larger, and spiral shell
Spin line rotation also easy material leakage when gathering materials.And because knife combination part 3 is consistent with helix rotating tendency in the present invention, cutter head 34
Be projected on helix, when cutter head 34 milling road surface because Impact direction unanimously makes cutter head rotation even wearing and milling
Cut effect more preferably, overcome and have angle between existing cutter head and helix and the cutting resistance that leads to is big, and be unfavorable for that material residue is received
The problem of collection.
The present invention is coordinated with tool rest 32 by conical tooth set 33, and cutter head 34 is at work by the reaction to milling object
Power enables conical tooth set 33 to be fitted close with tool rest 32, overcomes the tooth set of prior art presence and tool rest cooperation easily loosens
Problem, and the tooth set 33 of taper changed due to following little knocking out more easily by equipment such as crooked chisels above greatly.
The knockout plate 5 of the present invention is arranged on knockout plate flange 4 by bolt, so that after knockout plate 5 abrasion more
Change simpler convenience.
Exemplary, a kind of milling rotor of the present invention can also be applied to the large-scale milling device such as coal-cutting machinery equipment
On.
By the way, to solve the cutting resistance that existing milling rotor exists big for a kind of milling rotor of the present invention
And it is unfavorable for the shortcoming that material residue is collected.A kind of milling rotor helical-screw line of the present invention is end to end, smooth, reduces cutting road
Resistance during face, also substantially increases, while ensureing milling effect, the rate and adopt most rate of gathering materials, extend simultaneously cutter life,
Decrease later maintenance cost, and also significantly reduce the replacing difficulty of tool rest and knockout plate.
