Background technology
At present, the backhoe loader using is on the market two joint working arms, large arm, forearm and bucket, consists of.When the backhoe loader of existing two joint working arms is worked in highly lower tunnel, must sacrifice and excavate apart from using, while namely working, have to shorten the length of big and small arms in highly lower tunnel, cause like this and excavate apart from less, when large arm lifts, ceiling is easily encountered in large forearm junction, causes and delays work, mistakes simultaneously, and very dangerous, the adjustable range of loader working arm is limited, and working range is little, and efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic hammer to hit the arm-type loader-digger of breaking three joint, and this loader can be worked and need not sacrifice excavation distance in highly lower tunnel.
For achieving the above object, the utility model has adopted following technical scheme: comprise the large arm assembly and the little arm assembly that are hinged, described little arm assembly is connected with bucket assembly, on described large arm assembly, little arm assembly and bucket assembly, be respectively equipped with the big arm cylinder, oil cylinder of small arm and the bucket cylinder that drive its action, between described large arm assembly and little arm assembly, be provided with middle arm assembly, described middle arm assembly is provided with the middle arm oil cylinder that drives its action, and described middle arm assembly is hinged and connected with large arm assembly and little arm assembly respectively.
One end of large arm assembly of the present utility model is connected by bearing pin with middle arm assembly, the other end of described large arm assembly fixes by bearing pin and large arm seat, one end of described big arm cylinder is connected by bearing pin with large arm seat, and the other end of big arm cylinder is connected by bearing pin with large arm assembly.
One end of middle arm oil cylinder of the present utility model is connected by bearing pin with middle arm assembly, and the other end of middle arm oil cylinder is connected by bearing pin with large arm assembly.
One end of oil cylinder of small arm of the present utility model is connected by bearing pin with little arm assembly, and the other end of oil cylinder of small arm is connected by bearing pin with middle arm assembly.
Little arm assembly of the present utility model is provided with quartering hammer assembly, and described quartering hammer assembly is provided with the push cylinder that drives its action.
One end of push cylinder of the present utility model is connected by bearing pin with little arm assembly, and the other end of described push cylinder is connected by bearing pin with quartering hammer assembly.
Quartering hammer assembly of the present utility model is connected with little arm assembly by first, second bent plate.
As shown from the above technical solution, the utility model by setting up a middle arm assembly between original large arm assembly and little arm assembly, while working in tunnel, can, according to tunnel size, regulate big arm cylinder, middle arm oil cylinder and oil cylinder of small arm to regulate length and the height of whole working arm.While working in highly lower tunnel, big arm cylinder can be shortened, reduce the height of whole working arm, by arm oil cylinder in regulating and oil cylinder of small arm, whole working arm is extended again, while meeting work, excavate the requirement of distance, in shorter tunnel, need not sacrifice and excavate apart from also working; Simultaneously little arm assembly is provided with quartering hammer assembly and bucket assembly, and both can practical function conversion under the effect of drive unit, with time do not need use back and forth manually to change bucket and quartering hammer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of hydraulic hammer as shown in Figure 1 hits the arm-type loader-digger of breaking three joint, comprise the large arm assembly 1 and the forearm assembly 2 that are hinged; forearm assembly 2 is connected with bucket assembly 3; on large arm assembly 1, forearm assembly 2 and bucket assembly 3, be respectively equipped with big arm cylinder 4, oil cylinder of small arm 5 and the bucket cylinder 6 that drives its action; between large arm assembly 1 and forearm assembly 2, be provided with middle arm assembly 7; middle arm assembly 7 is provided with the middle arm oil cylinder 8 that drives its action, and middle arm assembly 7 is hinged and connected with large arm assembly 1 and forearm assembly 2 respectively.
Further, one end of large arm assembly 1 is connected by bearing pin with middle arm assembly 7, the other end of large arm assembly 1 fixes by bearing pin and large arm seat 9, and one end of big arm cylinder 4 is connected by bearing pin with large arm seat 9, and the other end of big arm cylinder 4 is connected by bearing pin with large arm assembly 1.
Further, one end of middle arm oil cylinder 8 is connected by bearing pin with middle arm assembly 2, and the other end of middle arm oil cylinder 8 is connected by bearing pin with large arm assembly 1.
Further, one end of oil cylinder of small arm 5 is connected by bearing pin with forearm assembly 2, and the other end of oil cylinder of small arm 5 is connected by bearing pin with middle arm assembly 7.
