Abstract
The utility model discloses a kind of coal mine stagewise double-geared roller crusher Special crushing teeth, including broken crown and fluted disc, broken crown and fluted disc are separate structure, broken crown one end is circular cone or cylindrical pin, fluted disc one end is circular cone or the fixed cave of cylinder, circular cone or the fixed cave of cylindrical pin and circular cone or cylinder match, and fit closely together；Broken crown and fluted disc are linked together by high strong ties bolt, high-strength high nut and combined type acorn nut.In the utility model, the fixed cave of circular cone or cylinder of the circular cone or cylindrical pin and fluted disc of broken crown limits displacement axially and radially, and associated junction fits closely, so that the utility model sound construction is reliable, durable；Broken crown and fluted disc are split type structure, it is very convenient to replace crown, to extend the service life of coal mine stagewise double-geared roller crusher crushing teeth, the quality and stability of product is improved, the overall technology for improving coal mine stagewise double-geared roller crusher is horizontal.
Description
Technical field
The utility model relates to a kind of crusher crushing teeths, more particularly to a kind of coal mine stagewise double-geared roller crusher
Special crushing tooth belongs to coal mining processing technique field.
Background technique
In recent years, coal mine grading toothed roller crusher is answered as a kind of novel energy-saving environment-friendly type equipment by market extensively
With, since the machine is using shearing and the smashing principle stretched, and optimization tooth form and the high manganese material of microalloying are used, it can fragment
Expect intensity≤200MPa brittle rock.Having this crusher, breaking strength is high, production capacity is big, low energy consumption, the vulnerable part service life is long
Etc. series of advantages, especially suitable for the industries such as coal, electric power, chemical industry use.Raw coal is passed through except iron, removal of impurities, without dirt extraction
It is directly crushed, broken coal process flow can be simplified in this way, reduce the construction investment and producing cost of mine, power plant.It is big at present
More coal mine grading toothed roller crusher level-one broken material granularities is big, and original material size to be broken reaches 1200mm-
1500mm, spoil content is big, and instantaneous up to 60% or more.It is especially serious for the abrasion and impact of crushing teeth.What is used now is big
Majority is the ring crush tooth of one piece casting type.After abrasion after a period of time, discharging-material size will increase the ring crush tooth,
It is unable to reach customer requirement.So a kind of especially needed safe intensity is equivalent at present or higher, crown can be with dismounting and change
Crushing teeth, on the one hand improve product the quality of production and stability, needed after on the other hand changing entire ring crush odontotripsis
The waste of integral replacing.
Utility model content
The utility model aim to solve the problem that former ring crush tooth can not quick-replaceable the drawbacks of, a kind of coal mine stagewise is provided
Double-geared roller crusher Special crushing tooth, to improve the quality of production and stability of product, after changing entire ring crush odontotripsis
Need the waste of integral replacing.
The technical solution that the utility model is taken in order to solve the technical problem is as follows:
A kind of coal mine stagewise double-geared roller crusher Special crushing tooth, including broken crown and fluted disc, the crushing teeth
Hat and fluted disc are separate structure, and described broken crown one end is circular cone or cylindrical pin, and described fluted disc one end is circular cone or cylinder
Fixed cave, the circular cone or cylindrical pin and the fixed cave of circular cone or cylinder match, and fit closely together；The broken crown
It is linked together with fluted disc by high strong ties bolt, high-strength high nut and combined type acorn nut.
The broken crown is to split column, is integrally cast by wear-resisting wear and shock-resistant steel alloy, is needed after hot investment casting
Heat treatment, by milling machine processing and fluted disc joint face, the positioning cylinder circular cone pin shaft that lathe vehicle system is connect with the fixed cave of fluted disc, boring system
The bolt connecting hole for connecting crown and fluted disc is needed with counterbore face is bolted using above-mentioned joint face as benchmark face spot-facing.It will be upper
It is flat to state counterbore bottom surface ream.The material of above-mentioned broken crown also can be used 40Cr and forge molding, and wear resistance electrode is used after molding
D256 paving weldering 5mm or more is substituted.
The fluted disc is formed by superior alloy steel hot investment casting, needs to be heat-treated after hot investment casting, by Boring machine processing and crown
The fixed cave of the cylinder circular cone of joint face, numerical control machining center boring system and crown positioning cylinder taper bolt axis connection and crown and fluted disc
Bolt connecting hole, be bolted counterbore face need using above-mentioned joint face as benchmark face spot-facing.Above-mentioned counterbore bottom surface ream is put down.
The broken crown and fluted disc are connect after being machined using high-strength bolt, nut using high-strength high nut with combine
The locking of formula acorn nut.The fixed cave of the cylinder circular cone of the positioning cylinder circular cone pin shaft of above-mentioned crown and fluted disc is combined closely after locking
Together, double limitation and fixation axially and radially is played.Played after combined cover shape nut check it is locking, locking and
The multi-functional of bolt is protected, this sound construction is reliable, durable.
The utility model changes the problem of replacing hardly possible, waste of material after previous integral ring-shaped odontotripsis fails, and improves
The production quality of product, improves the technical level of product, and use scope is wide, there is application value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is made further explanation with reference to the accompanying drawing:
Embodiment: referring to Fig. 1, a kind of coal mine stagewise double-geared roller crusher Special crushing tooth, including broken 1 He of crown
Fluted disc 2, is crushed crown 1 and fluted disc 2 is separate structure, and being crushed 1 one end of crown is circular cone or cylindrical pin 6, and 2 one end of fluted disc is
Circular cone or the fixed cave 7 of cylinder, circular cone or cylindrical pin 6 and circular cone or the fixed cave 7 of cylinder match, and fit closely together；It is broken
Broken crown 1 and fluted disc 2 are linked together by high strong ties bolt 3, high-strength high nut 4 and combined type acorn nut 5.
Broken crown 1 is integrally cast by wear and shock-resistant steel alloy, fluted disc 2 by superior alloy steel hot investment casting and
At.
The circular cone of broken crown 1 or the fixed cave of the circular cone or cylinder of cylindrical pin and fluted disc 2 limit axially and radially
Displacement, associated junction fits closely, so that this sound construction is reliable, durable.
