Description
Technical field
The present invention relates to a kind of excavator, a kind of excavator new structure for phosphorus ore mine is specifically referred to.
Background technology
Bull-dozerIt is a kind of engineering truck, front is equipped with large-scale metal dozer blade, and dozer blade is put down when using, backing-off cutting and pushes mud, husky and stone etc. forward, soil-shifting cutter position and angle can be adjusted.Soil-shifting function individually completes shoveling, muck haulage and unloads geotechnological work, and with operating, flexible, rotation is convenient, requiredWorking faceIt is small, the features such as travel speed is fast.It is primarily adapted for use in one toThree classes soilThe short fortune of shallow cut, such as site clearing or smooth, cutting depth is littleFoundation ditchAnd backfill,Push away and buildIt is highly littleRoadbedDeng.Crawler beltFormula bull-dozer (track-type
Tractor, also there is title crawler dozer）It is by American Benjamin
What Holt was succeeded in developing in 1904, it beCaterpillar tractorThe bulldozing device of men hoisting above is installed and is formed, power at that time isSteam engine, succeed in developing afterwards and successively by natural gas power drive andGasoline engineThe crawler dozer of driving, bulldozesPerching knifeAlso developed into by men hoistingSteel wire ropeLifting.Benjamin
Holt is also the U.S.Ka TeBi Le（Caterpillar Inc.）One of founder of company, nineteen twenty-five 5Holt manufacturing company and C.L, Best bull-dozerCompany amalgamation, compositionCaterpillarBull-dozer company, as the world first earth-moving equipment producer, and in offline first use of success in 1931Diesel engine60 bull-dozers.With the continuous progress of technology, soil-shifting mechanomotive force is all usedDiesel engine, bulldozing shovel blade andRidge busterAll byHydraulic cylinderLifting.Bull-dozer in addition to crawler dozer, alsoTireFormula bull-dozer, its appearance was than crawler dozer late ten years or so.Because crawler dozer has preferable adhesion property, can play biggerTractive force, therefore at home and abroad, the kind and quantity of its product are considerably beyond wheeled dozer.In the world,CaterpillarIt is construction machinery production company maximum in the world, the crawler dozer of its production has large, medium and small totally 9 series D3-D11, maximum D11
RCD, diesel engineFlywheelPower reaches 634kw；JapanLittle Song（komatsu）Company's row second, just start within 1947 to introduce production D50 crawler dozers, crawler dozer has 13 series, from D21-D575, that minimum is D21, and diesel engine flywheel power is 29.5kw, and that maximum is D575A-3SD, diesel engine flywheel power reaches 858kw, and it is also bull-dozer maximum on our times；The other one bull-dozer manufacturing enterprise for showing unique characteristics is GermanLiebherr group（Liebheer）, its bull-dozer is all using quietHydraulic pressureDrive, the technology releases model machine in 1972 after the research and development of more than ten years, starts within 1974 to produce PR721-PR731 in batches
With PR741 hydrostatic drive crawler dozers, due toHydraulic ElementsLimitation, its peak power is only 295Kw, and model PR751 is mining.
At present, it is complicated because operating environment is severe when the engineering machinery such as bull-dozer, land leveller uses ridge buster, service load, impact load are all larger, and the ratch and crown stress of ridge buster are larger, easily cause damage, the service life of ratch and crown is reduced, cost is improved, and influences the benefit of enterprise.
The content of the invention
It is an object of the invention to provide a kind of excavator new structure for phosphorus ore mine, the use scope of ridge buster is improved, while extending its service life.
The purpose of the present invention is achieved through the following technical solutions：
A kind of excavator new structure for phosphorus ore mine, including square connecting plate, the otic placode with axis hole is installed in the both sides on the fishplate bar top, trapezoidal securing plate is welded between two otic placodes, in the ratch of the arc of the bottom centre position welded bands bucket tooth of the connecting plate, reinforcing plate is welded between the square edge of the connecting plate and the outer wall of the ratch, alloy sleeve is provided with by bearing pin on the inside of the curved surface of the ratch arc, set with teeth is installed by bearing pin on the bucket tooth top, two projections of arc are provided with the bucket tooth lower outside wall, and the projection is upwardly extended along the side that tooth set bottom is pointed in bucket tooth bottom, the thickness size of the projection extends along direction and is incremented by.During work, the connection end of the engineering machinery such as excavator machine is inserted into the axis hole of otic placode by connecting shaft, constructing operation is carried out to Work places, due to being welded with reinforcing plate between the square edge of connecting plate and the outer wall of the ratch, and then the intensity of ratch is increased；Set with teeth is installed by bearing pin on bucket tooth top, and two projections of arc are provided with the lateral wall of bucket tooth bottom, so that bucket tooth bottom is when with material substrate contact, relative extruding is formed between bucket tooth lateral wall and material matrix, and projection causes that bucket tooth lateral wall is quickly cut in material matrix as the cushion space that the extruding force discharges, accelerate the loosening of material matrix, facilitate the excavation and transhipment of material, wherein so-called material matrix refers to the geologic structures such as soil horizon, concrete layer or lithosphere.And the thickness of projection extends along direction and is incremented by so that with going deep into for bucket tooth, the space that extruding force effect is discharged between bucket tooth lateral wall and material matrix is stepped up, and further improves the incision efficiency of bucket tooth.
The bottom of the bucket tooth lateral wall is provided with crown, the crown is inclined along the direction that its bottom is pointed at bucket tooth top.The crown that is obliquely installed is so that the end of bucket tooth has a high intensity and sharp keen incision inferius, while incision resistance of the material matrix to bucket tooth can be reduced, while so that the material of rolling is quickly moved in projection upwards.
The present invention compared with prior art, has the following advantages and advantages：
1st, projection of the invention causes that bucket tooth lateral wall is quickly cut in material matrix as the cushion space that the extruding force discharges, accelerate the loosening of material matrix, facilitate the excavation and transhipment of material, wherein so-called material matrix refers to the geologic structures such as soil horizon, concrete layer or lithosphere.And the thickness of projection extends along direction and is incremented by so that with going deep into for bucket tooth, the space that extruding force effect is discharged between bucket tooth lateral wall and material matrix is stepped up, and further improves the incision efficiency of bucket tooth；
2nd, the crown that is obliquely installed of the present invention is so that the end of bucket tooth has a high intensity and sharp keen incision inferius, while incision resistance of the material matrix to bucket tooth can be reduced, while so that the material of rolling is quickly moved in projection upwards.
