Abstract
The utility model relates to a graded crusher machine part, the especially broken tooth structure of graded crusher tooth machine. It includes the toothholder, and broken tooth, broken tooth pass through the connecting piece with the toothholder and be connected. Compared with the prior art, the utility model, simple structure, it is convenient to change, the wearing and tearing back appears when broken tooth, the whole fluted roller that does not need to be changed, it can the work of returning to normal only to change the serious broken tooth that weares and teares, and sparingly the accessory expense has shortened maintenance time, has improved work efficiency.
Description
Technical field
This utility model relates to Sizing Crusher parts, particularly a kind of graded crushing tooth crusher machine toothing.
Background technology
Crushing teeth is the core work parts of Sizing Crusher, and its structural behaviour directly decides the quality of equipment overall performance.The material that underground coal mine produces also has the hard materials such as a large amount of spoils, sandstone in addition to coal.These materials have higher hardness, the most broken, and to crushing teeth serious wear.The most conventional crushing teeth uses one piece casting pattern mostly, crushing teeth and broken toothholder are an overall structure, cannot be individually replaced, must change whole crushing toothed roller after abrasion after crushing teeth fracture, maintenance capacity is big, maintenance cost is high and cannot on-the-spot change, the normal production in serious restriction colliery.
Utility model content
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of Sizing Crusher crushing teeth structure, including toothholder, crushing teeth, crushing teeth is connected by connector with toothholder.
This utility model compared with prior art, simple in construction, it is convenient to change, after there is abrasion in crushing teeth, it is not necessary to changing whole discaling roll, the crushing teeth only changing serious wear can recover normally to work, save fittings cost, shorten maintenance time, improve work efficiency.
Preferred version of the present utility model is:
The wedge shaped structure of toothholder, on this toothholder, the connection end with crushing teeth is provided with positive stop key structure.
The groove structure matched with positive stop key structure it is provided with on crushing teeth.
Positive stop key structure is positioned on the axially symmetric centrage of toothholder.
The installation through hole passed for connector it is respectively arranged with on toothholder and crushing teeth.
Installation through hole on crushing teeth is hierarchic structure: squared counter bore-manhole.
Lifting through hole it is provided with on crushing teeth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment describes this utility model in detail:
A kind of Sizing Crusher crushing teeth structure, sees accompanying drawing 1 to accompanying drawing 3, in figure: toothholder 1, nut 2, bolt 3, crushing teeth 4, positive stop key structure 5, manhole 6, squared counter bore 7, lifting through hole 8, groove structure 9.
In the present embodiment, crushing teeth 4 and toothholder 1 is connected by bolt 3, and the non-threaded end of bolt 3 is square structure, and bolt 3 end of thread is connected with nut 2.
The wedge shaped structure of toothholder 1, this is as shown in fig. 1；On toothholder 1, the connection end with crushing teeth 4 is provided with positive stop key structure 5；Positive stop key structure 5 is positioned on the axially symmetric centrage of toothholder 1；Being provided with the groove structure 9 matched with positive stop key structure 5 on crushing teeth 4, matches with the side end face of positive stop key structure 5 in two sides of groove structure 9.
The installation through hole passed for bolt 3 it is respectively arranged with on toothholder 1 and crushing teeth 4；Installation through hole on crushing teeth 4 is hierarchic structure: squared counter bore 7 and manhole 6；Squared counter bore 7 adapts with the bolt of square structure end built with the square structure end of bolt 3, squared counter bore 7, and when preventing crushing teeth 4 from sufficiently large power occurring, bolt 3 loosens and produces rotation phenomenon.Lifting through hole 8 it is provided with on crushing teeth 4；Lifting through hole 8 is in order to dismantle the convenience of crushing teeth 4.
This utility model simple in construction, it is convenient to change, and after abrasion occurs in crushing teeth 4, it is not necessary to changing whole discaling roll, the crushing teeth 4 only changing serious wear can recover normally to work, saves fittings cost, shortens maintenance time, improve work efficiency.
Claims (2)
1. a Sizing Crusher crushing teeth structure, including toothholder, crushing teeth, it is characterised in that: crushing teeth is connected by connector with toothholder；The wedge shaped structure of toothholder, on this toothholder, the connection end with crushing teeth is provided with positive stop key structure；Being provided with the groove structure matched with positive stop key structure on crushing teeth, matches with the side end face of positive stop key structure in two sides of groove structure；Lifting through hole it is provided with on crushing teeth；The installation through hole passed for connector it is respectively arranged with on toothholder and crushing teeth；Installation through hole on crushing teeth is hierarchic structure: squared counter bore-manhole.
