Specific implementation mode

Following will be combined with the drawings in the embodiments of the present invention, is clearly and completely retouched to the technical solution in embodiment It states.Obviously, described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this hair Bright embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that, term "center", " transverse direction ", " longitudinal direction ", "front", "rear", The orientation or positional relationship of the instructions such as "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outside" is It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description of the present invention and simplification of the description, rather than instruction or dark Show that signified device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as pair The limitation of the scope of the present invention.

For material distributing cone wearability it is poor, it is frequent replace so that the higher problem of production cost, inventor has carried out greatly The experimental study of amount finds the degree of wear of each region on material distributing cone by research and differs that some regions wears must compare More serious, some regions wear degree are then slight, i.e. heterogeneity feature is presented in the abrasion of material distributing cone, if therefore in sub-material Integral replacing is carried out to it after taper thread grinding damage, it will the problem for causing the effective rate of utilization of the part wear-resistant material of material distributing cone relatively low.

In order to improve the effective rate of utilization of wear-resistant material as much as possible, making full use of for material distributing cone some materials is realized, originally Invention proposes a kind of crusher rotor body.

As shown in Figure 5 and Figure 6, which includes material distributing cone 2 and rotor disk 4, and material distributing cone 2 is arranged in rotor disk 4 center, specifically, crusher rotor body further include shaft, and material distributing cone 2 and rotor disk 4 are connect with shaft, and with shaft It rotates together.

Rotor disk 4 is equipped with multiple flow channel components 3, and multiple flow channel components 3 are located at the periphery of material distributing cone 2, to be formed for object The logical runner of stream, runner are equipped with discharge port 6, spaced apart between two neighboring flow channel component 3, form discharge port 6.

As being rotated on runner for rotor block 1 forms material lining 7, material is fallen from above rotor disk 4 on material distributing cone 2, object Expect under the action of material distributing cone 2 into the runner for expecting lining 7, to serve as a contrast 7 surfaces to outward transport along material under the influence of centrifugal force It is dynamic, until being dished out by discharge port 6.

It is dismountable to serve as a contrast the region of 7 tail ends close to material on material distributing cone 2；And/or close to material 7 tail ends of lining on material distributing cone 2 The wearability in region is better than the wearability in other regions.

Specifically, these contain three kinds of specific implementation modes, the first is on material distributing cone 2 close to the area of material 7 tail ends of lining Domain is detachable structure, the regions wear to a certain extent after, individually the region locally can be replaced so that Other regions other than the region are fully utilized；Be for second the region wearability it is more wear-resisting than other regions Property it is good, can make in this way the region have better wearability, the replacement frequency of the region material is reduced, but also other areas The material in domain is fully utilized；The third is that the region is detachable structure, and the wearability in the region is than other The wearability in region is good, not only allows the region to carry out independent replacement in this way, can also reduce the region material more Frequency is changed, the material in other regions is made to be fully utilized, reduces manufacturing cost.These three embodiments are to dividing The transformation carried out close to the region of material 7 tail ends of lining on material cone 2.

Wherein, the tail end of material lining 7 refers to that with discharging direction be reference, apart from the one end of discharge port 6 farther out.In Fig. 6 institutes In the embodiment shown, rotor block 1 rotates counterclockwise, and the flow process of material forms respectively Flow of Goods and Materials rail in three runners Mark L1, L2 and L3, these tracks area defined A, B, C are on above-mentioned material distributing cone 2 close to the region of material 7 tail ends of lining, These regions are also the relevant range of each rotor flow tract initial segment.

Inventor is by carefully studying discovery, collision, friction more frequent, the abrasion of generation of the material in these regions It is even more serious compared with other regions, thus in above-mentioned each embodiment targetedly by these regions be set as detachable structure or Person's wearability is more preferable, can be separately replaced upon wear, and the replacement frequency of material distributing cone is reduced, and makes full use of other regions Material.
