Description

technical field [0001] The device of the invention relates to the technical field of engineering machinery, in particular to a new energy excavator. Background technique [0002] Excavators are important construction machinery, and excavators also play a very important role. The publication number is CN205205890U, which discloses a new type of mini excavator. The mini excavator includes a body and an internal combustion engine arranged on the body. One end of the internal combustion engine is provided with a hydraulic pump, and the bottom of the body is provided with two walking tracks. The bulldozing mechanism is connected through the connecting rod, and the bulldozing mechanism is connected to the body; one end of the body is connected with a boom of the size of a bucket, and the control cylinder is set on the boom of the size of the bucket; the lower end of the body is connected with the slewing device, and the body is equipped with a control valve. . Control cylinder a...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned excavator needs to rotate the body as a whole to achieve the purpose of swinging the large and small booms of the bucket along the left and right sides of the driver. Since the internal combustion engine, fuel tank and other components are all installed on the body, the internal combustion engine and fuel tank also rotate with the body. In this way, for the rotary motor in the rotary device, a large output power is required to be able to drive. Since this rotary is a regular operation, the hydraulic pump and the rotary motor will be in a high-power output state for a long time , the slewing motor is supplied with hydraulic oil by the hydraulic pump, and the hydraulic pump is driven by the internal combustion engine, long-term slewing operation will cause the fuel consumption of the internal combustion engine to increase

[0006] (3) The above-mentioned running mechanism is composed of a transmission mechanism and a crawler belt. For this kind of running mechanism, since the crawler belt will become longer after use, the cooperation between the crawler belt and the transmission mechanism will loosen, resulting in a decrease in the transmission efficiency of the running mechanism.

[0007] (4), the body includes a rotary disc connected to the rotary device, a housing with an internal cavity, and a driving position. One end of the housing is fixedly connected to the rotary disc, the other end of the housing is closed, and the driving position is fixed on the other side of the housing. One end; for the body of this structure, since the internal combustion engine and the hydraulic pump are located inside the housing, and there are other components such as oil pipes in the housing, once these parts fail and need to be repaired, the entire housing needs to be replaced. Very inconvenient to disassemble and maintain
