With the loader of crushing function
Technical field
The invention belongs to engineering machinery field, the loader particularly with crushing function.
Background technology
Existing loader, is mainly used in shovel and coalings the loose unpacked materials such as charcoal, sandstone, earth, rubbish, fertilizer.Some loaders take off scraper bowl, install quartering hammer in arm front end, for impacting rock, cement pavement, and the operations such as old room removal.Quartering hammer great majority are arranged on excavator arm front end, in the wild construction and Reconstruction of City Road in consumption very large.Quartering hammer is installed on board a dredger, and more more convenient than being arranged on loader, reason is: 1, the spacing of loader two arm is comparatively large, and quartering hammer must be reinforced one block of larger steel plate, loader arm is connected and fixed with steel plate again.Quartering hammer adds upper steel plate, and appearance and size is very large, and loader goes out to construct, and carries very inconvenient.And excavator arm only has one, quartering hammer can be directly installed on arm front end.Further, above quartering hammer, there is no steel plate, can directly hang on scraper bowl, easy to carry.2, more important point is that excavator arm is accompanied the emperor and sailed room and can rotate together.After crushing hammar drill rod impacts certain point, can be very fast at excavator arm front transverse shifting, displacement is little, being equivalent to arm swings, drill steel can be aligned second shock point, and horizontal multiple shock point, and excavator wheel or crawler belt do not move, very convenient.But loader arm does not possess spinfunction.The crushing hammar drill rod installed of arm front end impacted certain a bit after, transverse shifting, and transverse shifting distance is little again, loader drive person only starts loader, and wheel advances or retreats, left avertence or right avertence, even repeatedly, the next point that drill steel will impact can just be aligned.Two arm of loader to rotate up and down, can not lateral rotation, so drill steel wants the distance that transverse shifting is not many, driver's operation bothers, and when both taking a lot of work, efficiency is low again.
Summary of the invention
The object of the present invention is to provide a kind of loader random installation to have quartering hammer, and impact in operation at quartering hammer, transverse shifting drill steel can be facilitated to aim at the novel loader of shock point.
The present invention is achieved in that and a small breaking hammer or pneumatic pick, electric pick is arranged in the frame of top between loader two front-wheels, wears at random.
With the loader of crushing function, primarily of loader, frame, pedestal, principal arm, yoke, arm seat, on turn oil cylinder, horizontal oil cylinder, folding oil cylinder, quartering hammer composition.Be arranged on yoke front end and carry out having quartering hammer, electric pick and using compressed-air actuated pneumatic pick of impact grinding operation, be below referred to as quartering hammer.Between loader two front-wheels, the front lower place of the frame of top is fixedly connected with pedestal.Arm seat is arranged in pedestal.Principal arm is arranged on arm seat.Quartering hammer is arranged on yoke.Yoke and principal arm make one.Principal arm rear end hinge is on arm seat.Quartering hammer hinge is in yoke front end.Arm seat is fixed with support.There is a block pressur plate to be pressed on the body of wall on pedestal both sides above arm seat, with screw, pressing plate is tightened on the body of wall of pedestal both sides.With pivot pin from the axis hole above pressing plate through the axis hole arm seat and the following axis hole of pedestal, the mounted location of arm seat.Arm seat can carry out back rotation angle in pedestal.Oil cylinder comprises piston rod and cylinder body, hereinafter referred to as oil cylinder.On turn oil cylinder one end and stand hinge, the other end and principal arm hinge, can make to rotate before and after principal arm, up and down.Folding oil cylinder one end and yoke hinge, the other end and quartering hammer hinge, can hammer the angle with yoke into shape by controlled fragmentation.Horizontal oil cylinder one end and airframe hinge, the other end and stand hinge, can make the pivot pin of support around arm seat center carry out back rotation, thus drive the quartering hammer on principal arm, yoke also can carry out back rotation around arm seat central axis pin.Principal arm, yoke, quartering hammer can turn left and right in the front of loader, although be one section of camber line of a larger circle, for loader dead ahead, quartering hammer can move laterally left and right.Quartering hammer, after certain point of impact, laterally can proceed to second, the 3rd shock point.And loader does not start, and wheel carrys out left avertence, right avertence makes quartering hammer aim at second, third shock point.Driver's operation can be made to simplify, improve work efficiency.Behind loader front all impact grinding, carry out larger apart from traversing, just start loader wheel and carry out traversing.On turn oil cylinder, folding oil cylinder can make principal arm, yoke, quartering hammer folding and unfolding is in frame.During quartering hammer operation, top lifted by the scraper bowl of loader, and during the scraper bowl operation of loader, quartering hammer is retractable in frame.
Advantage of the present invention is: 1, impact grinding instrument worn at random by loader, does not need take off scraper bowl and install quartering hammer during use.2, quartering hammer can in loader front interim traversing variation shock point.And before loader fragmentation impact and will change front and align some positions, be to start loader, mobile wheel left avertence, right avertence, advance, retrogressing, carry out sequence of operations and just can complete.The present invention makes quartering hammer interim traversing fast, can be simple to operate, increases work efficiency again.
