Abstract
The utility model discloses a kind of power shovel, including bucket body, toothholder plate and bucket tooth, the toothholder plate is fixed on bucket body, the bucket tooth includes crown and toothholder, the toothholder is integral type structure with toothholder plate, the point of the crown is provided with wear-resistant ball, and the wear-resistant ball sinks into crown and partly exposed to be covered with one layer of wearing layer on crown, the crown outer wall.The scraper bowl intensity is big, wearability is good, can effectively extend scraper bowl service life, reduces the operation and maintenance cost of excavator.
Description
Technical field
The utility model belongs to excavator field, and in particular to a kind of power shovel.
Background technology
Scraper bowl is also bucket, is to be used to excavate the device higher or lower than machine side material is held on excavator, wherein bucket tooth is
Important component on power shovel, is also easily worn part similar to the tooth of people, the bucket tooth generally used at present by toothholder and
Crown is constituted, and toothholder is fixed on scraper bowl, and toothholder and crown are connected by bearing pin, the material that excavator is excavated be mainly soil,
Coal, silt and soil and rock after pre- pine, because these materials largely have higher hardness and intensity, in length
In the operation of phase, bucket tooth crown is easy to abrasion, it is necessary to change crown after crown is worn failure.The replacing of crown both shadow
Job schedule has been rung, operating efficiency has been reduced, excavator working service cost is substantially increased again.
The content of the invention
In order to solve the above problems, the utility model discloses a kind of power shovel, the scraper bowl intensity is big, wearability is good,
Scraper bowl service life can effectively be extended, the operation and maintenance cost of excavator is reduced.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of power shovel, including bucket body, toothholder plate and bucket tooth, the toothholder plate are fixed on bucket body,
The bucket tooth includes crown and toothholder, and the toothholder is integral type structure with toothholder plate, and the point of the crown is provided with wear-resisting
Ball, the wear-resistant ball sinks into crown and partly exposed to be covered with one layer of wearing layer on crown, the crown outer wall.
Toothholder of the present utility model is integral type structure with toothholder plate, compared to conventional bearing pin connection, bolt connection, riveting
The connected mode such as connect more solid and reliable, be not in loosen, come off even phenomenon of rupture, makes whole scraper bowl more firm resistance to
With, and by setting wear-resistant ball in bucket tooth crown, and wearing layer is covered with crown outer wall, substantially increase the hardness of crown
And wearability, the service life of scraper bowl is effectively extended, the use cost and maintenance cost of excavator is reduced.
The wear-resistant ball material is diamond compact or cubic boron nitride.Diamond compact and cubic boron nitride
Hardness is all far above the hardness of other materials, thus scraper bowl can be avoided to be ground in higher the material such as coal cinder, rock of excavation hardness
Damage deformation.
Further, the wearing layer is diamond film.Diamond film is attached to crown outer surface, the hard of crown is improved
Degree and wearability.
It is preferred that, the bucket body, toothholder and toothholder plate use abrasion-resistant stee HARDOX.Improve bucket body and toothholder
The intensity of plate, prevents from being worn and torn by material, while strengthening the intensity of toothholder, prevents it from deforming or being broken.
The utility model compared with prior art, has the following advantages and advantages：
(1) because toothholder and toothholder plate are integral type structure, compared to conventional bearing pin connection, bolt connection, riveting etc.
Connected mode is more solid and reliable, is not in loosen, come off or even phenomenon of rupture, makes whole scraper bowl more sturdy and durable；
(2) by setting wear-resistant ball in bucket tooth crown, and wearing layer is covered with crown outer wall, substantially increases crown
Hardness and wearability, and bucket body, toothholder and toothholder plate use abrasion-resistant stee HARDOX, can prevent scraper bowl from being deformed in working
Or fracture, improve the service life of scraper bowl, it is sturdy and durable because scraper bowl and bucket tooth have very high intensity, thus without through
Bucket tooth is often changed, the use cost and maintenance cost of excavator is reduced, operating efficiency is improved.
