Abstract
The utility model relates to a digging machine, which can effectively save energy and consume less fuel. A technical proposal is that: the digging machine is provided with a large arm and a rotating platform. The digging machine is characterized in that : a fixed plate is externally connected with the rear of the large arm. The fixed plate is hinged with one end of a connecting rod, which is arranged on the top of the rotating platform. One end of a lever arm is hinged with the other end of the connecting rod. A balance weight iron is connected with the other end of the lever arm. The upper end of the rear of the rotating platform is provided with a supporting structure. The supporting structure is hinged with the lever arm. Because the balance weight iron is movable. The position of the balance weight iron changes in company with the change of the position of the large arm. The self weight of the large arm is balanced by the balance weight iron. The digging machine only undertakes a shoveling burden, and the digging machine no longer bears the self weight of the big arm. Idle work for the large arm is avoided. Working efficiency is enhanced. More than 50 percent of the fuel can be saved.
Description
Technical field: the utility model relates to a kind of novel excavator.
Background technology: at present, existing excavator balance weight iron all is fixed on the afterbody of revolving dial, and every excavation once, machine works is got up not only will overcome the weight of material, overcomes the weight of big arm in addition, has done a lot of idle works, waste a lot of energy, increased fuel consumption.
The utility model content: the technical problems to be solved in the utility model provides a kind ofly can effectively save energy, novel excavator that fuel consumption is little.Technical scheme: a kind of novel excavator, has big arm, revolving dial, it is characterized in that: the afterbody of big arm is circumscribed with fixed head, and an end of fixed head and connecting rod is hinged, and connecting rod is positioned at the top of revolving dial, one end of the other end of connecting rod and lever arm is hinged, another termination balance weight iron of lever arm, the afterbody top of revolving dial is provided with fixed mount, and lever arm and fixed mount are hinged.Beneficial effect: because balance weight iron of the present utility model is movable, the position changes along with the variation of big arm position, the deadweight of big arm is carried out balance by the weight of balance weight iron, excavator is only born the shoveling load, no longer bear big arm from heavy load, avoided big arm is made idle work, operating efficiency improves, and oil plant can be saved more than 50%.
Description of drawings:
Fig. 1 is existing excavator structure schematic diagram;
Fig. 2 is the structural representation of one of the utility model duty;
Fig. 3 is two a structural representation of the utility model duty;
Fig. 4 is three a structural representation of the utility model duty;
Fig. 5 is four a structural representation of the utility model duty.
The specific embodiment: show as Fig. 2, excavator has big arm S, revolving dial D, the afterbody of big arm is circumscribed with fixed head H, the end of fixed head and connecting rod E is hinged, one end of pitman arm can rotate around fulcrum F, connecting rod is positioned at the top of revolving dial D, the end of the other end of connecting rod and lever arm C is hinged, another termination balance weight iron A of lever arm, the afterbody top of revolving dial is provided with fixed mount G, and lever arm and fixed mount are hinged, lever arm can be around pin joint B swing, and lever arm is certain radian at pin joint B for one section to balance weight iron.To shown in Figure 5, during excavator work, along with the change in location of big arm S, lever arm rotates as Fig. 2, and the corresponding balance weight iron position that makes changes the holding torque balance.When big arm descends, with the weight and the lever force of big arm balance weight iron is lifted, when big arm lifts, big arm is lifted with the weight and the lever force of balance weight iron, overcome big arm deadweight.
