Abstract
The utility model discloses a bucket of a hydraulic excavator, which comprises a bucket body, wherein a bucket teeth plate and a main cutting plate are connected to the front end of the bucket body, bucket teeth are connected to the bucket teeth plate and the main cutting plate, and different included angles are formed among the central planes of the bucket teeth. As the bucket teeth are arranged at certain angular intervals instead of being arranged in the same direction, when the bucket digs a rock stratum, not all the bucket teeth conduct the digging at the same time, i.e. the bucket teeth conduct the digging in sequence, and the contact area of the bucket teeth and the rock is much smaller than that in a traditional arrangement method. Therefore, under equal digging force, the lineal pressure ratio of the bucket to the rock is increased, and the digging resistance is reduced; and by virtue of the compression of the bucket teeth previously in contact with the rock, the bucket teeth in contact with the rock afterwards are much easier to insert into rock cracks to extrude and burst the rock stratum, thus the rock is easy to tear apart and dig down. While digging a limestone formation, the bucket not only can reduce the digging resistance but also improve the digging efficiency, and is mainly used for hydraulic excavators.
Description
Technical field
The utility model relates to a kind of Hydraulic Excavator Bucket of excavating lime rock stratum that is applicable to.
Background technology
At present, hydraulic crawler excavator bucket tooth commonly used on the market is the operator plate that is arranged in scraper bowl in the same way, when digging operation, all bucket tooths contact the cubic metre of earth and stone simultaneously, such bucket tooth arrangement is applicable to and excavates the following soil of III level, but for III level or soil more than the III level or rock, if directly allowing all bucket tooths directly contact lithosphere carries out digging operation and can produce sizable excavating resistance, and the increase of excavating resistance can cause the quick-wearing of crossing of bucket tooth, also can cause of short duration overburden operation, even can cause the bearing pin fracture, production accident takes place.Earlier rock blasting is opened if adopt, carry out the method for digging operation again, digging operation efficient can reduce a lot.
Summary of the invention
Cause crossing quick-wearing, causing of short duration overburden operation of bucket tooth in order to overcome excavating resistance conference that existing Hydraulic Excavator Bucket occurs when excavating lime rock stratum, even can cause the defective that bearing pin ruptures, the utility model provides a kind of Hydraulic Excavator Bucket, this scraper bowl can increase the line pressure ratio of scraper bowl to excavating rock, reduce excavating resistance, can not cause the quick-wearing of crossing of bucket tooth.
The technical scheme that its technical problem that solves the utility model adopts is: this scraper bowl comprises bucket body, and the bucket body front end is connected with bucket tooth plate and operator plate, and bucket tooth plate and operator plate are connected with bucket tooth, are provided with different angles between each bucket tooth median plane.
With the scraper bowl bucket tooth in the same way arranged make the alternate certain angle of each bucket tooth into and arrange, like this when the excavating rock layer, be not that whole bucket tooths are participated in digging operation simultaneously, bucket tooth can carry out digging operation successively, and the contact area of the method for arranging that the contact area of bucket tooth and rock is more traditional is much smaller.Therefore, under onesize digging force, can increase the line pressure ratio of scraper bowl, reduce excavating resistance rock.And the extruding force of the bucket tooth that contacts behind utilization and the rock can make the bucket tooth that contacts earlier with rock more easily be inserted in the rock fracture, distending is pushed in the rock stratum, so just more easily rock is torn and dug down, be poured at last in the scraper bowl, finish whole mining process.
Advantage of the present utility model: when excavating lime rock stratum, can reduce excavating resistance, can improve digging efficiency again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model scraper bowl.
Fig. 2 is the lateral view of the utility model scraper bowl.
1. bucket bodies among the figure, 2. packing ring, 3. bolt, 4. side tooth, 5a. toothholder, 5b. toothholder, 5c. toothholder, 5d. toothholder, the 5e. toothholder is 6. sold 7a. bucket tooth, 7b. bucket tooth, 7c. bucket tooth, 7d. bucket tooth, 7e. bucket tooth, 8. operator plate, 8a. skewed slot, 9. side cutting plate, 10. bucket tooth plate, 11. nuts.
The specific embodiment
In Fig. 1 and Fig. 2, operator plate 8, side cutting plate 9, bucket tooth plate 10 and bucket body 1 weld together; Toothholder 5a and 5e are symmetrically welded on bucket tooth plate 10, have skewed slot 8a in the middle of the operator plate 8, and toothholder 5c is welded among the skewed slot 8a of operator plate 8, and toothholder 5b and 5d are symmetrically welded on operator plate 8; Side tooth 4 is fixing by bolt 3, packing ring 2 and nut 11 with side cutting plate 9; Bucket tooth 7a is connected by pin 6 respectively with toothholder 5e with toothholder 5d, bucket tooth 7e with toothholder 5c, bucket tooth 7d with toothholder 5b, bucket tooth 7c with toothholder 5a, bucket tooth 7b.
Be provided with angle theta between bucket tooth 7a and the bucket tooth 7b
1, θ among the figure
1=11 °, be provided with angle theta between bucket tooth 7b and the bucket tooth 7c
2, θ among the figure
2=14 °.Bucket tooth 7a and bucket tooth 7e are in the same plane; Bucket tooth 7b and bucket tooth 7d are positioned on another plane.
Excavator is when operation, the whole bucket tooths that are not scraper bowl carry out operation simultaneously, but the bucket tooth 7a at the two ends of scraper bowl contacts earlier with rock with 7e, contact rock to compare contact area much smaller with whole bucket tooths, therefore its unit cutting force also can increase, bucket tooth easier being inserted in the rock fracture just like this, and then smash macadam; Bucket tooth 7b and 7d participate in digging operation then, because bucket tooth 7b and 7d be to the effect of the extruding force of rock, rock can reduce much so just to be more prone to destroy rock to the excavating resistance of bucket tooth 7a and 7e, and digging efficiency has also had certain raising; Be in the middle bucket tooth 7c of scraper bowl at last and participate in digging operation, cutting resistance is further reduced, reached the purpose of high-efficient homework.
