Abstract
The invention discloses an excavator bucket which comprises a bottom plate and side plates arranged on the two sides of the bottom plate. The front end of the bottom plate is externally connected with a guide plate in the direction of the bottom plate, the side plates are perpendicular to the bottom plate and the guide plate at the same time, and the side plates on the two sides are parallel. The width of the guide plate is equal to that of the bottom plate. Bucket openings formed in the middles of the top faces of the side plates are in an arc shape. The rear side of the bottom plate is connected with a lug plate with a pin shaft, two central holes are formed in the lug plate, and the distance between the two central holes is 564+/-5 mm. Under the condition that the width of the front end of the bucket is kept unchanged, the volume of the bucket is increased. Meanwhile, the contact area of the bucket and operation soil is reduced, and digging resistance is reduced to acquire the maximum digging potential.
Description
Technical field
The present invention relates to vehicle scraper bowl, specifically a kind of power shovel.
Background technology
At present, angle between two blocks of side plates of the power shovel on market and guide plate, base plate adopts obtuse angle structure, and the quarrel plane of two blocks of side plates designs for linear structure, this structure scraper bowl suffered resistance in the time excavating is larger, excavate difficulty, increase main pump intensity of load, caused the power waste of excavator.Seem particularly important so research and develop a kind of power shovel that can effectively reduce excavating resistance.
Summary of the invention
The object of the present invention is to provide a kind of power shovel, can effectively reduce the excavating resistance of power shovel, reduce the power waste of machine.
In order to reach above-mentioned purpose, the present invention has adopted following technical scheme, a kind of power shovel, comprise base plate and be arranged on the side plate of base plate both sides, the front end of described base plate is along picking out a guide plate, and described side plate, simultaneously perpendicular to base plate and guide plate, is parallel to each other the side plate of both sides.
The width of described guide plate and base plate equates.
The quarrel position that described side plate end face middle part forms is circular arc.
Described base plate rear side connects the otic placode with bearing pin, offers two centre bores on otic placode, and the distance of two centre bores is 564 ± 5mm.
Compared to prior art, the present invention has following beneficial effect:
Ensureing, in the constant situation of bucket front-end width, to have increased bucket capacity.Reduce scraper bowl and operation soil contact long-pending simultaneously, reduce excavating resistance, exploit potentialities to obtain maximum.
Brief description of the drawings
Fig. 1 is the top view of a kind of power shovel of the present invention;
Fig. 2 is the lateral view of a kind of power shovel of the present invention.
In figure: 1, guide plate; 2, side plate; 3, base plate; 4, otic placode.
Detailed description of the invention
Relevant detailed description of the present invention and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the present invention to be limited.
With reference to accompanying drawing 1-2, a kind of power shovel, comprises base plate 3 and is arranged on the side plate 2 of base plate both sides, and the front end of described base plate 3 is along picking out a guide plate 1, and described side plate, simultaneously perpendicular to base plate and guide plate, is parallel to each other the side plate of both sides.The width of described guide plate and base plate equates.The quarrel position that described side plate end face middle part forms is circular arc.Described base plate rear side connects the otic placode 4 with bearing pin, offers two centre bores on otic placode.
The circular arc at the R place of side plate 2 is towards the opening direction of scraper bowl, and with vertical welding of plane of leading operator plate 1, base plate 3, then otic placode is welded on scraper bowl.
Operator plate 1 width of common power shovel is 1800mm, the wide 1500mm of base plate 3 rear end, the plate 1 of now operating is unified for 1650mm, in the time that power shovel carries out the action of " receipts " and " exhibition " with the width of base plate 3, biside plate can not produce pressure drag with soil, makes to excavate more laborsaving.
The quarrel position of side plate 2 was a line originally, the circular arc that is now 6000mm for radius, and when power shovel " receipts ", arc radius is basically identical therewith for the profiling track of scraper bowl, has reduced the resistance of soil to scraper bowl, makes to excavate more laborsaving.
The distance of 4 two centre bores of otic placode was 510 ± 5mm originally, was now 564 ± 5mm, in the situation that hydraulic system provides moment of torsion constant, had increased the arm of force, made to excavate more laborsaving.
The foregoing is only preferred embodiment of the present invention, non-in order to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
