Description
Technical field
The utility model relates to a kind of power shovel scraper bowl, the power shovel scraper bowl on a kind of excavator is related particularly to, is belonged to slow
Tilt the outdoor phosphorus ore extractive equipment technical field of thin body.
Background technique
It is well known that the scraper bowl of existing power shovel is all the scraper bowl class using mating installation on corresponding bull-dozer on the exploiting field of mine
Type.Power shovel is bought from house is produced, applies power shovel in each mine exploiting field, following tripartite's planar defect facts have proved by many years production.
Firstly, the service condition of power shovel, first introduces several technical terms: first is that loss late, loses industrial mine amount and should adopt
The percentage of industrial mine amount, second is that the rate of extraction, produces industrial mine amount and should adopt the percentage of industrial mine amount；Third is that the rate of dilution, is adopted
The grade of yield ores reduces number and should adopt the percentage of industrial mine amount grade；Fourth is that barren rock incorporation rate, it is mixed into extracted ore useless
Stone amount and the percentage for adopting yield, by actually making to power shovel in sharp mountain phosphorus ore, Kunyang, Jinning County, scene, phosphorus ore exploiting field
It is analyzed with situation, according to the geologic change situation for adopting stripping scene, stripping scheme is adopted in optimization, and the selection of mining methods directly affects
Ore poor loss rate should comprehensively consider the factors such as bed geological condition, exploitation economic technology, select from a variety of mining concepts appropriate
Method, to reduce the poor loss rate of ore, adopt yield maximization, the utilization of resources rationalize.
Kunyang, Jinning County's phosphorus ore and sharp mountain phosphorus ore are when adopting stripping, according to orebody occurrence, attitude Characteristics, using " dew
Its longwall " recovery method, ore carries out horizontal fragmentation selective mining after explosion in advance, digging machine adopts dress.Ground carries out quick-fried in advance
After broken, dress is adopted using power shovel, digging machine, directly transport refuse dump to and carries out casting, earthing and operation of reclaiming by planning.
Drilling machine is cooperated using the high-power bull-dozer of SD22, D85, MD23, cleans ore faces, while matching using D9R, D9T, D275
Power shovel cleaning removing ore triangle body is closed, to reduce being mixed into for interlayer top plate barren rock, to reduce the loss and dilution of ore.
Powerful SD22, D85, MD23 bull-dozer and D9R, D9T, D275 bull-dozer, corresponding scraper bowl are all to produce house to go out
Mating installation when production uses always in exploiting field, plays act on well at the scene, but the problem is that: it is powerful
The scraper bowl of SD22, D85, MD23 bull-dozer is also big, and the bucket tooth of its tip is longer, in the interface operation of ore bed and rock stratum,
As long as slightly causing the dilution of ore not note that bucket tooth is shoveled easily through rock stratum in ore bed, ore bed and interlayer, interlayer and
The interface of lower layer's mine is all easy to mix and wear, causes the depletion loss of ore, so for many years, can not all change always, and only
The driver that operation bull-dozer can be depended merely on artificially controls, and loses caused by this is just often artificial, is a to mine minerals resource
Very big loss.Theoretically the actual poor loss rate of the requirement to mine ore resource poor loss rate and exploiting field scene has severe deviations,
It is all significantly larger than to report value and theoretical value.
The bucket tooth of existing SD22, D85, MD23 are longer, are all fixed and invariable, at single rock stratum or ore bed, very
Good operation, can freely operate up and down in stripping bench altitude range, can give full play to the strong point of equipment, but in rock stratum
When nearby doing industry with the interface of upper ore bed, upper ore bed and interlayer, interlayer and lower layer's mine, lower layer's mine and bottom plate, due to bucket tooth compared with
It is long, it is difficult the depth that control is excavated, it is easy to shuttle in each interlayer, the poor damage of ore accidentally just occur, as long as not infusing slightly
Meaning just directly influences the poor loss rate of ore, the severe deviations that ore occurs, and in the big position of tomography or formation variation, produces
Raw poor damage is bigger.Theory points out that the ore body near tomography or triangle body should be collected sufficiently, can actually do at exploiting field scene
Less than this point；Meanwhile plate back and forth boring into can have ore-rock powder stone blocking channel when boring, on channel, it is difficult to remove blocking
Rubble miberal powder in channel etc., how to exclude blocking channel is a difficult problem: since steel plate is fastened using flange bolt,
Once blocking occurs it is necessary to timely block clearing on plate return channel, in order to reduce blockage phenomenon, channel back and forth will be designed
At closing, valve is set up in place, to control distance back and forth, screw troublesome thing of having got rusty will be comed one after another,
In actual operation, blocking is almost all occurring all the time, in order to reduce plugging machine meeting, channel is had to be designed to close
, but blocking still can exist, and the excavation body toothholder welding of traditional structure, tooth set are mounted on toothholder by alligator
On, tooth inner room and tooth set outside are without block, and there are problems: first is that tooth set and alligator two sides are without block, tooth covers during the work time
Deviate from due to multiple impacts vibration causes alligator to loosen, tooth set is caused to fall, it, can be further if loading onto new tooth set not in time
It causes toothholder to wear, scraps entire excavator；Second is that tooth cover tooth tip between excavator quarrel at a distance from it is larger, take relatively dissipate
When material, material is easily leaked out from inter-lobe clearance.
Currently, when the rock stratum that removing to ore is contacted with overburden, being used in production during ore topsoil stripping
Mini-excavator carries out overburden operation.For this layer, if digging machine is excessive, that scraper bowl is also larger, and the tooth of scraper bowl is longer, clear
When managing rock stratum, as long as operation does not pay attention to slightly, it is easy to ore bed is hurt, through in ore bed, ore bed and rock stratum are mixed removing together,
Lead to the depletion loss of ore.On the contrary, being impacted if digging machine is smaller to charge stripping efficiency and removing progress.It excavates simultaneously
In use, scraper bowl bottom plate and side plate are relatively easy to wear machine, are usually all the sides using replacement bottom plate and reinforcing side plate
Method carries out reparation use to scraper bowl.
Therefore, need to develop a kind of functional reliability it is higher and it is efficient and convenient remove blocking excavator on power shovel scraper bowl
It is the key point for solving above-mentioned technical problem.
