Description
Technical field：
The present invention relates to a kind of excavator bucket teeth, more particularly to a kind of wear-resistance excavator bucket teeth.
Background technology：
At present, the excavator bucket teeth that uses of mining is largely casting, the structure of bucket tooth be it is trapezoidal, it is wide at the top and narrow at the bottom,
Inside there are rectangular apertures, bucket tooth tip is flat, double surface grooving.In mining process, using two arms of excavator to bucket tooth and
Tipping bucket is reinforced, and bucket tooth tip directly contacts scar, bucket tooth is excavated with rock gap in very stiff and demanding mode, bucket tooth is whole
The face stress of body three, be entirely by straight cutting, grab plane in the way of excavated, certain protection is not formed to bucket tooth in design and is made
With making denticle easily wear and tear.Meanwhile, manufactured using foundry engieering so that bucket tooth density is small, hardness is low, easy to wear, usage cycles
It is short.When being exploited to rock type ore, the service life of bucket tooth is only 5~7 days, and especially granite ore body is dug
During pick, formation hardness is reached between HSD70~80, and the bucket tooth of general performance can not be born.
The content of the invention：
A kind of wear-resistance excavator it is an object of the invention to provide service life length, suitable for excavating granite ore body
Bucket tooth.
The present invention is implemented by following technical scheme：A kind of wear-resistance excavator bucket teeth, it includes crown, active section and connection
Section, one end of the active section is crown, and the other end of the active section is linkage section, and the end of the linkage section is provided with wedge shape
Pin shaft hole is provided between link slot, the two sides of the linkage section, the pin shaft hole is connected with the wedge-shaped link slot；The work
The upper surface for making section is to be inlaid with antifriction alloy bar in the middle part of streamlined curved surface, the streamlined curved surface, is produced available for rock gap
Raw broadening effect, reduces bucket tooth and the front friction of rock gap, while producing a reaction force to sillar, mitigates crown in tipping bucket
When frictional force；The lower surface of the active section is provided with herringbone reinforcement, and the head of the herringbone reinforcement is provided with wear-resisting
Alloy block.Bottom is when digging, in order that ore body is steadily moved, the reinforcing of two arms, bucket tooth and two arms basically form 45° angle, bottom
Wear-resisting alloy block plays protection bucket tooth bottom, the friction of sillar and bucket tooth is reduced, while being also played to sillar certain
Drag effect, prevents landing of the rock in translation motion；The lateral middle of the crown is inlaid with antifriction alloy plate, can mitigate
Bucket tooth tip and the positive stress of rock gap, while playing wear-resistant effect.
Specifically, the top surface of the antifriction alloy bar is arc-shaped surface, and is protruded outside the streamlined curved surface, it is described resistance to
Two sides of the both ends of the surface of break-in gold bar respectively with the active section are concordant.
Specifically, the top surface of the wear-resisting alloy block is arc-shaped surface, and is protruded outside the herringbone reinforcement surface,
Two sides of the both ends of the surface of the wear-resisting alloy block respectively with the herringbone reinforcement head are concordant.
Specifically, the front end face of the antifriction alloy plate is concordant with the front end face of the crown, the antifriction alloy plate
Two sides of the both sides end face respectively with the crown are concordant.
Specifically, the thickness of the antifriction alloy plate is 1/3rd of the crown thickness.
Specifically, being inlaid with wear strip respectively in the middle part of the two sides of the active section, bucket tooth both sides surface wear is effectively prevented.
Operation principle explanation：Airflow design theory is used in design, and airflow design belongs in terms of sport dynamics
Relatively more rational design, especially excavation campaign of the bucket tooth between rock gap, rubble, gravelly sand, it may appear that various power, and it is streamlined
The bucket tooth of design can reasonably distribute these power, and effectively extend the service life of bucket tooth；After rock blasting, it will produce
Substantial amounts of irregular cracks, rubble, gravelly sand, excavator is when clearing up these ore bodies, it is necessary to which a kind of various aspects of performance is all very strong
Bucket tooth.The workflow of excavator：Tipping bucket is dug bucket tooth crown insertion rock gap --- reinforcing of the arm of excavator two ---
Dress --- play bucket and transport.The stress point of this process is concentrated mainly on the crown of bucket tooth, the streamlined upper surface of bucket tooth active section
Middle part and the bottom of bucket tooth active section.When the crown of bucket tooth inserts rock gap, with the reinforcing of the arm of excavator two, bucket tooth crown is
Rock gap depths is inserted, active section starts to expand rock, and tipping bucket is dug, and the middle part of the streamlined upper surface of bucket tooth active section is contacted with scar,
The area of reaction force is increased, sillar is departed from rock mass, while bucket tooth active section streamlined upper surface middle part stress, also subtracts
The light vertical stress of crown, now the arm of excavator two reinforce again, the streamlined upper surface middle part of crown, active section, active section
Bottom is filled with the digging of tipping bucket, and three faces produce frictional force with ore body simultaneously, and tipping bucket transports ore body translation, and this is perfectly excavated
Process, only airflow design could reduce the abrasion of bucket tooth and ore along with three pieces of alloy blocks are to the overall protection of bucket tooth,
Extend the service life of bucket tooth.
It is an advantage of the current invention that (1) uses forging molding so that bucket tooth globality is intact, steel body density is big, wear resistence
By force, hardness is high, and disposable die sinking, is used for multiple times in process；(2) service life of bucket tooth is extended to 13~15 days,
Times of bucket tooth replacement is reduced, cost is reduced, energy consumption environmental protection is saved；(3) bucket tooth external form uses airflow design theory, bucket tooth
Various power occur when being excavated to rock gap, rubble, gravelly sand, the bucket tooth of airflow design can reasonably distribute these power, extension
The service life of bucket tooth.
