Hydraulic Excavator Bucket
Technical field
The utility model is applied to Hydraulic Excavator Bucket, particularly relates to the Hydraulic Excavator Bucket of cutting edge increase protected mode in the Hydraulic Excavator Bucket.
Background technology
At present, the cutting edge of Hydraulic Excavator Bucket, the part when digging operation between its bucket tooth is is very easily worn and torn, when may wear to a certain degree and effect at digging force under this position can produce stress and concentrate, thereby cutting edge will be torn and cause scrapping of whole scraper bowl.
Summary of the invention
The purpose of this utility model be to provide a kind of when digging operation the position between the bucket tooth may wear to a certain degree and under the effect of digging force, can not concentrate and not to be torn owing to stress; and long service life, simple in structure, with low cost, cutting edge can obtain the Hydraulic Excavator Bucket of good protection.
Technical solution of the present utility model is such: a kind of Hydraulic Excavator Bucket comprises scraper bowl, protects tooth and bucket tooth.It is characterized in that: protect tooth between the bucket tooth of scraper bowl, it is L shaped protecting odontoid, and has circular hole for welding, adopts welding high strength alloy steel casting.
The utility model has the advantages that, cast the tooth that protects that forms but add weldering welded high-strength alloy steel between the bucket tooth of Hydraulic Excavator Bucket, scraper bowl position between the bucket tooth when digging operation may wear to a certain degree and can not be torn owing to stress is concentrated under the effect of digging force.Have long service life, simple in structure, with low cost, dependable performance, cutting edge can obtain the advantage of good protection.

The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to Fig. 1~Fig. 5, on the basis of original Hydraulic Excavator Bucket (1) body, scraper bowl (1) go up bucket tooth (3) but between add that the casting of weldering welded high-strength alloy steel forms protect tooth (2).Protect tooth (2) for L shaped and have welding with circular hole (4).The overall structure of scraper bowl does not change, and has just increased safeguard measure in the part.But make power shovel have long service life, simple in structure, with low cost, dependable performance by transformation of the present utility model, cutting edge can obtain advantages such as good protection.
The utility model only needs to add weldering between bucket tooth (3) and protects tooth (2) on the basis of original power shovel, and it is simple in structure, and is easily manufactured.Protect tooth (2) for L shaped and have welding with circular hole (4), materials are economized, and weld seam can be effectively protected.Miscellaneous part need not be changed greatly basically, realizes prolonging the scraper bowl purpose in application life easily.
The utility model does not limit use on the scraper bowl of hydraulic crawler excavator, may also extend on the scraper bowl of engineering machinery such as loader.
