Description
Technical field
The present invention relates to a kind of scraper bowl of engineering machinery, particularly a kind of excavator vibration scraper bowl.
Background technology
The bucket tooth of the scraper bowl that present excavator uses all connects as one with scraper bowl, having efficiently fast during for the general soil property of excavation, advantage is widely used in the civil engineering, but when excavating block object, because the feature that block has firm no regularity and should not pulverize, can only rely on the slip between the block during excavation, irregular block thing is digging under the power effect, tend to make the material compacting and resistance significantly increases, thereby digging efficiency is significantly reduced, increased excavate costs.
Summary of the invention
The objective of the invention is to provide a kind of excavator vibration scraper bowl, solve minimizing that present excavator can't overcome and excavate stiction that block produces, and excavator inefficient problem when excavating block.
The object of the present invention is achieved like this: the vibrating type scraper bowl is made up of bucket tooth, permanent tooth, amplitude amplifier, piston rod, end cap, piston chamber, piston, in-line, oil return line, scraper bowl body and piston rod, bucket tooth is socketed on the permanent tooth, permanent tooth and scraper bowl body connect as one, bucket tooth is connected with the amplification end of amplitude amplifier, the other end of amplitude amplifier is connected with piston rod, piston rod passes end cap central seal ring and is connected with piston, end cap is fixed in the piston chamber, piston and piston chamber's contact seal; Piston chamber, in-line, oil return line are cast in the scraper bowl body, and in-line, oil return line are connected with the servo valve of hydraulic power unit.
Described amplitude amplifier is made up of kinetic energy piece and wave-transmitter, and wave-transmitter one end is connected with the kinetic energy piece, and the other end is connected with bucket tooth, and the kinetic energy piece is connected with piston rod; Described wave-transmitter is spring or memory material thin plate.
Beneficial effect: owing to adopted such scheme, end cap is isolated into two cavitys with piston chamber and amplitude amplifier, end cap and piston, in-line, oil return line are formed hydraulic cylinder, hydraulic oil enters the promotion piston motion by in-line, piston can be converted to thrust with hydraulic pressure, pass to amplitude amplifier by piston rod, amplitude amplifier is converted to mechanical wave with mechanical energy, offer bucket tooth by permanent tooth, bucket tooth produces kinetic energy generation vibrations generation impact force makes material loosening, reduces excavating resistance raising digging efficiency.The present invention has used amplitude amplifier technology and structure first on scraper bowl, solved minimizing that present excavator can't overcome and excavated stiction that block produces, and excavator inefficient problem when excavating block, digging efficiency is greatly improved.Adopt action, parts integral structure form good manufacturability, fault to hang down and satisfied requirement of mass production.
Advantage:
1, the impact kinetic energy of bucket tooth vibrations generation makes material loosening, has improved excavation speed and has saved excavate costs.
2, adopted the parts integral structure, close with existing scraper bowl manufacturing process, be convenient to product up-gradation.
3, because the bucket tooth vibrations can artificially be controlled, do not influence former existing excavation function, enlarged the product scope of application.
