Background technology
Along with engineering construction fast, extensively carry out, the development of also constantly bringing forth new ideas of various building machineries.Excavator has served as important role in numerous engineering activities.Through a large amount of engineer's practices, excavator technology also improves constantly, and efficiency of construction is improved greatly.
At present, the excavator of applying in engineering divides the types such as crowd shovel, backhoe, grab jaw according to its use principle, substantially can meet instructions for use.But due to the difference of execution conditions, some place need to be excavated some place and need to be pushed away and fill out, and the excavator of this simple function just has certain limitation.If need backhoe excavation to need again crowd shovel to push away, dig, can only be used alternatingly two kinds of excavators in existing technology, efficiency of construction can not improve simultaneously.In addition, in constructing tunnel process, because work plane is narrow, just can not use two kinds of excavation machines, a kind of reversible excavator just can solve problems simultaneously.
Summary of the invention
The utility model provides a kind of reversible excavator, for solving the problem that under different construction conditions, the positive and negative automatic conversion of excavator is used.
The technical solution of the utility model is: a kind of reversible excavator, comprises base 1, boom cylinder 2, swing arm 3, bucket arm cylinder 4, dipper 5, bucket cylinder 6, chain bar 7, scraper bowl auxiliary oil cylinder 8, crowd shovel bucket tooth 9, backhoe bucket tooth 10, scraper bowl 11, wherein base 1 is arranged in excavator base machine main body, swing arm 3 is arranged on base 1 and by connecting the flexible swing rotary of controlling swing arm 3 of the boom cylinder 2 of base 1 and swing arm 3, swing arm 3 ends and dipper 5 are hinged, one end of bucket arm cylinder 4 is connected on swing arm 3, the other end of bucket arm cylinder 4 is connected with dipper 5 and by the flexible swing rotary of controlling dipper 5 of bucket arm cylinder 4, dipper 5 ends and scraper bowl 11 are hinged, one end of bucket cylinder 6 is connected on dipper 5, one end of the other end of bucket cylinder 6 and scraper bowl auxiliary oil cylinder 8 and to be connected to the one end of the chain bar 7 on dipper 5 hinged, the other end of chain bar 7 is connected with dipper 5, the other end of scraper bowl auxiliary oil cylinder 8 is connected on scraper bowl 11, crowd shovel bucket tooth 9 and backhoe bucket tooth 10 are set on scraper bowl 11.
Described scraper bowl 11 is designed to semicircle form of fracture.
The course of work of the present utility model is:
The same with traditional excavator operation, by control lever, control oil cylinder and stretch to realize excavation.
While carrying out backhoe excavating, handle the coordination combination of boom cylinder 2, bucket arm cylinder 4, bucket cylinder 6 and scraper bowl auxiliary oil cylinder 8 and extend, scraper bowl 11 is the anti-shape of grabbing, and 10 of backhoe bucket tooths are fitted with excavated surface, excavates.Continue each oil cylinder combination of operation and extend, control the rotation of swing arm 3 and dipper 5, shovel slag can be transported by scraper bowl.Handle each oil cylinder contraction and can realize deslagging.
While carrying out crowd shovel excavation, handle the coordination combination of boom cylinder 2, bucket arm cylinder 4, bucket cylinder 6 and scraper bowl auxiliary oil cylinder 8 and shrink, lower swing arm 3 and dipper 5, swing arm 3, dipper 5, scraper bowl 11 are roughly point-blank.9 of crowd shovel bucket tooths are fitted with excavated surface, push away and dig forward.Continue to handle each oil cylinder and shrink, control on swing arm 3, dipper 5 and lift, shovel slag can be contained in scraper bowl and transport.Extend oil cylinder, reversible bucket can be realized deslagging.
Scraper bowl 11 is designed to semicircle form of fracture, can be controlled and be realized large rotation angle by oil cylinder; Dipper capacity designs according to mechanical output, can meet construction requirement; Scraper bowl auxiliary oil cylinder 8 is replaced traditional fixed chain bar, assists the large rotation angle of scraper bowl 11, increases rotation amplitude, makes to rotate more flexible.
The beneficial effects of the utility model are: simple in structure, easy to use; The function that not only possesses traditional positive and negative shovel excavator, also possess excavation, push away fill out, the function such as handling, lifting.
