The utility model discloses a be provided with respectively on big arm and forearm a plurality of with correspond the hinge hole that the hydro -cylinder is connected to can be according to excavating the on -the -spot different soil property condition, adjust the pin joint of corresponding hydro -cylinder and big arm or forearm, with the excavation power size that changes rock arm final output, thereby reach the best work efficiency, avoid the waste of the energy simultaneously.
Description
Technical field
The utility model belongs to construction implement technical field, particularly a kind of rock arm configuration excavated for native stone.
Background technology
At present in the building operations of road and bridge ground; usually rock arm can be used to excavate; and the strength of loosening the soil of existing rock arm is constant after mounting; namely the soil property no matter excavated is softer or harder; its excavation strength exported is consistent; and accommodation cannot be carried out according to actual excavation situation, thus in some excavation situation, best operating efficiency can not be reached and cause unnecessary energy waste.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of and according to the soil property situation of different conditions when excavating, can make the rock arm configuration of accommodation to the excavation strength of rock arm output.
The technical solution of the utility model is achieved in that a kind of rock arm configuration, comprise large arm, forearm, ridge buster, big arm cylinder, oil cylinder of small arm and ridge buster oil cylinder, described large arm and forearm hinged, described forearm bottom and ridge buster upper articulation, cylinder body end and the forearm of described ridge buster oil cylinder are hinged, its drive rod end and ridge buster hinged, cylinder body end and the large arm of described oil cylinder of small arm are hinged, it is characterized in that: in described large arm, be provided with at least two large arm hinge holes hinged with the driving rod end of big arm cylinder, described forearm is provided with at least two forearm hinge holes hinged with the driving rod end of oil cylinder of small arm.
Rock arm configuration described in the utility model, large arm described in it is case structure, is provided with at least one the reinforcing rib dividing plate being carried out its inner space separating, is provided with filler in each cavity after separation in described large arm.
Rock arm configuration described in the utility model, it is fixedly connected with axle sleeve at the large arm hinge hole place of described large arm, is provided with the reinforcement gusset be connected and fixed with axle sleeve in described large arm.
Rock arm configuration described in the utility model, ridge buster described in it comprises ridge buster body, backboard and otic placode, it is an overall structure that described otic placode is connected with ridge buster body by backboard, described forearm bottom and otic placode hinged, the driving rod end of described ridge buster oil cylinder by bar linkage structure and otic placode hinged, described ridge buster body is crescent, and the end sleeve of described ridge buster body is connected to bucket tooth.
The hinge hole that the utility model is connected by being respectively arranged with multiple and corresponding oil cylinder in large arm with forearm, thus can according to the different soil property situations of excavation site, regulate the pin joint of corresponding oil cylinder and large arm or forearm, to change the digging force size that rock arm finally exports, match with the requirement will excavating soil property to make the mining ability of rock arm, thus reach best operating efficiency, avoid the waste of the energy simultaneously.
