Abstract
A kind of breaker of crushing hard bulk materials, the device crown core wheel and F types crown are separate demountable structure, on the one hand different material and Technology for Heating Processing can be used to broken crown and discaling roll core wheel, so that crown has larger hardness, wearability and impact flexibility, and core wheel then has good intensity and processing technology, which improves the mechanical property of part, the processing cost of part is reduced；On the other hand when abrasion occur and needing to change crown, can only change crown again and without removing core wheel.This reduces the maintenance cost of equipment, material has been saved.
Description
Technical field
The utility model is related to a kind of breaker, specifically, be related to a kind of crushing hard bulk materials (such as oil shale,
Sandstone, spoil etc.) breaker.
Background technology
It is well known that toothed roll crusher is usually used in mining equiment, for bulk materials to be broken into technique needs
Piece material.This kind of disintegrating machine generally includes drive part, running part, broken segment etc., and broken segment is then the equipment
Key device.The broken segment of toothed roll crusher now uses monoblock type discaling roll, i.e. crushing teeth and System of Rotating about Fixed Axis mostly
Matrix make monoblock type.This structure type has following two shortcomings:First, crushing teeth needs have higher hardness, it is resistance to
Mill property, if making monoblock type, necessarily causes whole breaker hardness very high, is so unfavorable for machining, improves and adds
The difficulty of work technique；Second, under prolonged broken condition, crushing teeth will necessarily produce abrasion or even under extreme conditions can
Be broken, if making monoblock type, change discaling roll when just must integral replacing, so waste material, improve cost.
The content of the invention
In order to solve the above-mentioned technical problem, utility model provides a kind of breaker of crushing hard bulk materials, its
Main purpose is：On the one hand the device can use different material and Technology for Heating Processing to broken crown and discaling roll core wheel,
So that crown has larger hardness, wearability and impact flexibility, and core wheel then has good intensity and processing technology；It is another
Aspect when there is abrasion and needing to change crown, can only change crown again and without removing core wheel.
To achieve these goals, the technical solution adopted in the utility model is：A kind of crushing hard bulk materials are broken
Crushing device, it is characterised in that：Include crown core wheel and F type crowns, crown core wheel and F types crown are independently of each other detachable
Annexation；Crown core wheel is an overall structure, including middle plate-shaped base body and to be evenly distributed on plate-shaped base body cylindrical
All and outwardly directed claw type structure, detent and through hole are provided with claw type structure；It is crushing teeth knot outside F types crown
Structure, the groove corresponding with claw type structure is internally provided with, side is provided with detent and through hole, and F type crowns are enclosed on pawl
Type structural outer, by bolt through the corresponding detent and through hole in position, fixed F types crown and claw type structure it is relative
Position.
Described bolt axis is parallel with the tangential direction of crown core wheel rotational circle.
Described F types crown and the centre of crown core wheel phase-contact surface are plane, and both ends are the circular arc type knot extended downwardly
Structure, after being fixed using bolt, the circular arc type structure at F type crown bottoms both ends is in contact with the excircle of crown core wheel.
Described bolt is high-strength bolt.
The entering surface of described bolt through F types crown and claw type structure is the stretching direction of F type crown external fragmentation teeth,
As F types crown is rotated and broken force surface is carried out to material.
A detent and two through holes are provided with described each claw type structure.
The outside of described plate-shaped base body is evenly distributed with four claw type structures.
The beneficial effects of the utility model are：A kind of breaker of crushing hard bulk materials, the device is on the one hand
Different material and Technology for Heating Processing can be used to broken crown and discaling roll core wheel so that crown has larger hardness, resistance to
Mill property and impact flexibility, and core wheel then has good intensity and processing technology, which improves the mechanical property of part, drop
The low processing cost of part；On the other hand when abrasion occur and needing to change crown, can only change crown again and without tearing open
Except core wheel.This reduces the maintenance cost of equipment, material has been saved.

Embodiment
A kind of breaker of crushing hard bulk materials, its structure are：
Include crown core wheel 1 and F types crown 2, crown core wheel 1 and F types crown 2 are separate dismountable connection
Relation.
Crown core wheel 1 is an overall structure, including middle plate-shaped base body 1-1 and is evenly distributed on plate-shaped base body 1-1
Excircle and outwardly directed claw type structure 1-2, general plate-shaped base body 1-1 outside are evenly distributed with four claw type structure 1-2.
Detent 3 and through hole 4 are provided with claw type structure 1-2；A detent is provided with general each claw type structure 1-2
3 and two through holes 4.
The outside of F types crown 2 is broken toothing, is internally provided with the groove corresponding with claw type structure 1-2, side is set
Detent 3 and through hole 4 are equipped with, F types crown 2 is enclosed on outside claw type structure 1-2, and the corresponding positioning in position is passed through by bolt
Groove 3 and through hole 4, the relative position of fixed F types crown 2 and claw type structure 1-2.Described bolt is high-strength bolt, bolt
Axis is parallel with the tangential direction of the rotational circle of crown core wheel 1.
The centre of described F types crown 2 and the phase-contact surface of crown core wheel 1 is plane, and both ends are the circular arc type extended downwardly
Structure, after being fixed using bolt, the circular arc type structure at the bottom both ends of F types crown 2 is in contact with the excircle of crown core wheel 1.By
This, both direction has contact surface, makes contact and fixes more compact firm.
Described bolt through F types crown 2 and claw type structure 1-2 entering surface are the stretching of the external fragmentation tooth of F types crown 2
Direction, as F types crown 2 are rotated and broken force surface are carried out to material.
