The utility model relates to a kind of dipper and the outer dustproof construction of scraper bowl, comprise dipper, shovel head, bearing pin, T-shaped end cover and dust ring, dipper is provided with installing hole with shovel head, described bearing pin is through installing hole, inner side and the dipper end face of the flange convex surface of T-shaped end cover fit, the outside of flange convex surface fits with shovel head otic placode end face, and the inner ring of T-shaped end cover offers groove close to T-shaped end cover outer face place, and described dust ring is arranged in groove.The beneficial effects of the utility model are, dipper of the present utility model and the outer dustproof construction of scraper bowl, be arranged on dust ring in groove, avoid and the direct collision of foreign object, friction, effectively can protect dust ring, improve the effect of reliability, durability.
Description
Technical field
The utility model relates to a kind of dipper and the outer dustproof construction of scraper bowl.
Background technology
At present, the work under bad environment of hydraulic crawler excavator, be in excavation during work always, promote, revolution, discharging, revolution, prepare in the cycle operation of excavating, dipper and scraper bowl hinged place are often and earth, rubble contacts, therefore at the outer dust ring of hinged place design, prevent foreign object from entering hinged secondary inner, cause articulated structure inordinate wear, this type of design can extend the application life of hinged pair slightly, but in the work of long-term hydrostatic excavator, outer dust ring is frequent with outside material friction, collide with, its reliability can be caused, durability degradation, there is fracture, damaged problem, need after a period of operation to change outer dust ring (as shown in Fig. 1 Fig. 2).
Utility model content
The technical problems to be solved in the utility model is: in order to improve the application life of outer dust ring, and the utility model provides a kind of dipper and the outer dustproof construction of scraper bowl.
The utility model solves the technical scheme that its technical problem adopts: a kind of dipper and the outer dustproof construction of scraper bowl, comprise dipper, shovel head, bearing pin, T-shaped end cover and dust ring, dipper is provided with installing hole with shovel head, described bearing pin is through installing hole, inner side and the dipper end face of the flange convex surface of described T-shaped end cover fit, the outside of flange convex surface fits with shovel head otic placode end face, the inner ring of described T-shaped end cover offers groove close to T-shaped end cover outer face place, and described dust ring is arranged in groove.
In order to improve dust tightness, save material, the cross section of described dust ring takes the shape of the letter U, the outer face that U-shaped opening overlaps towards T-shaped end, and whole height is a little more than depth of groove.
The beneficial effects of the utility model are, dipper of the present utility model and the outer dustproof construction of scraper bowl, be arranged on dust ring in groove, avoid and the direct collision of foreign object, friction, effectively can protect dust ring, improve the effect of reliability, durability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the design of placing dust ring in prior art.
Fig. 2 is the A place enlarged diagram of Fig. 1.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is the I place enlarged diagram of Fig. 3.
Fig. 5 is the utility model groove structure schematic diagram.
In figure: 1, dipper, 2, dust ring, 3, T-shaped end cover, 31, groove, 4, installing hole.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As in Figure 3-5, it is embodiment of the present utility model, comprise dipper 1, shovel head, bearing pin, T-shaped end cover 3 and dust ring 2, dipper 1 is provided with installing hole 4 with shovel head, described bearing pin is through installing hole 4, and inner side and dipper 1 end face of the flange convex surface of described T-shaped end cover 3 fit, and the outside of flange convex surface fits with shovel head otic placode end face, the inner ring of T-shaped end cover 3 overlaps 3 outer face places close to T-shaped end and offers groove 31, and described dust ring 2 is arranged in groove 31.The cross section of described dust ring 2 takes the shape of the letter U, and U-shaped opening is towards the outer face of T-shaped end cover 3.
As can be seen from the contrast of Fig. 1 and Fig. 4, end puts to be placed the structure of dust ring and has done change, the outer end making dust ring direct contact part, can avoid friction, the damage caused of colliding with, and available protecting dust ring, improves application life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
