Abstract
The invention belongs to the technical field of mining and excavating equipment and particularly relates to a flap type shovel tooth comprising a shovel tooth body and two flaps. The flap type shovel tooth is characterized in that the shovel tooth body is a combined body of a tapered shovel edge at the front end and a fork-shaped connecting piece at the back end; the two flaps are quadrangular bodies with cross sections which are of isosceles trapezoids, and are respectively connected with two sides of the back part of the tapered shovel edge; and the fork-shaped connecting piece is fixedly connected with a bucket. The taper angle alpha on the tapered shovel edge on the shovel tooth body is 25-30 degrees. The fork-shaped connecting piece is provided with a mounting hole which is fixedly connected with the bucket. The flap type shovel tooth has the advantages that by utilizing the tapered shovel edge, the stress of the shovel tooth is more reasonable and the phenomenon that the root part of the shovel tooth is abraded and broken is avoided; the flaps are additionally arranged to form the sealed surface of the front arm of the bucket, so that the front arm of the bucket is protected, therefore, the service life of the bucket is prolonged, the times for replacing the bucket can be reduced, and the excavation production efficiency is improved.
Description
Technical field
The invention belongs to mining excavating equipment technical field, especially relate to a kind of flap type shovel tooth.
Background technology
In mine excavator, power shovel is one of capital equipment of mine excavation.The scraper bowl that directly is used for excavating transhipment is comprised of the scraper bowl that one group of teeth of front end is connected with one group of teeth therewith, and the structure of teeth is straight-tooth, in mining process, the straight-tooth front end contacts with work plane, and become 45 the degree～50 the degree angle be the excavating optimum state, but find the phenomenons such as often appearance is worn and torn, fracture is even scrapped after the long use of this straight-tooth structure of teeth, changed once in general about 2 months, affect scraper bowl life-span and operating efficiency.Analyze its reason, straight-tooth truncation surface unreasonable structure does not adopt the variable cross-section design according to force-bearing situation, to form the effective protection to teeth.
Summary of the invention
The invention provides a kind of flap type shovel tooth, solve teeth wearing and tearing, breakage problem, extend scraper bowl application life, improve the power shovel operating rate.
The objective of the invention is to realize by following technical proposals:
Flap type shovel tooth of the present invention, comprise two flaps that the teeth body is connected with teeth body therewith, it is characterized in that described teeth body is the assembly of the front end taper edge of shovel and rear end fork-shaped connector, described two flaps are that cross section becomes the four bank or ridge of isosceles trapezoid and is connected with the both sides at described taper edge of shovel rear portion respectively, and described fork-shaped connector is fixedly connected with scraper bowl.
The cone angle of the taper edge of shovel on described teeth body is 25 °-30 °.
Described fork-shaped connector is provided with the installing hole that is fixedly connected with scraper bowl.
Advantage of the present invention:
1) the present invention owing to adopting the taper edge of shovel, makes teeth stressed more reasonable, avoids teeth to occur in the phenomenon that the root wearing and tearing fracture;
2) the present invention increases flap, forms the sealing surface of scraper bowl forearm, protection scraper bowl forearm.Extended scraper bowl application life, bring up to about 3 year about by original half a year the application life that makes the scraper bowl forearm, improved application life 5-6 doubly, reduced scraper bowl and changed number of times, improved the excavation production operation efficiency, reduced maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1 of the present invention.
Specific embodiment party
Flap type shovel tooth of the present invention, comprise two flaps 2 that the teeth body is connected with teeth body therewith, it is characterized in that described teeth body is the assembly of the front end taper edge of shovel 1 and rear end fork-shaped connector 3, owing to adopting the taper edge of shovel, make teeth stressed more reasonable, avoid teeth to occur in the phenomenon that the root wearing and tearing fracture.Described two flaps 2 become the four bank or ridge of isosceles trapezoid and are connected with the both sides at the described taper edge of shovel 1 rear portion respectively for cross section, and described fork-shaped connector 3 is fixedly connected with scraper bowl.Described fork-shaped connector 3 is provided with the installing hole 4 that is fixedly connected with scraper bowl.Form the sealing surface of scraper bowl forearm, protection scraper bowl forearm.Extended scraper bowl application life, bring up to about 3 year about by original half a year the application life that makes the scraper bowl forearm, improved application life 5-6 doubly, reduced scraper bowl and changed number of times, improved the excavation production operation efficiency, reduced maintenance cost.
Claims (3)
