Efficient energy-saving environment-friendly oil-hydraulic hybrid powder excavator

Abstract

The invention discloses an efficient energy-saving environment-friendly oil-hydraulic hybrid powder excavator. The efficient energy-saving environment-friendly oil-hydraulic hybrid powder excavator comprises an upper frame, a swivel plate, a scraper bucket, a scraper bucket pin shaft connecting mechanism, a boom, a boom working device, an energy accumulator energy-charging device, an oil supply device and a rotating power assembly; the upper frame is mounted on the swivel plate which is connected to the rotating power assembly; the scraper bucket is assembled on a bucket rod by virtue of the scraper bucket pin shaft connecting mechanism; the boom is hinged to the bucket rod by virtue of the scraper bucket pin shaft connecting mechanism on one hand, and other the other hand, the boom is connected with the upper frame by virtue of an upper frame pin shaft; the boom working device is a three-cylinder boom working device; the oil supply device is a three-pump oil supply device; the three-cylinder boom working device is hinged between the boom and the upper frame; the energy accumulator energy-charging device, the three-pump oil supply device and the rotating power assembly are mounted on the upper frame, respectively, wherein the energy accumulator energy-charging device and the three-pump oil supply device both are connected with the three-cylinder boom working device. The efficient energy-saving environment-friendly oil-hydraulic hybrid powder excavator is very obvious in energy saving effect and also greatly improved in working efficiency.

Description

technical field [0001] The invention relates to an excavator, in particular to a high-efficiency, energy-saving and environment-friendly oil-liquid hybrid excavator. Background technique [0002] With the development of the national economy, excavators have become an indispensable machine in infrastructure construction, and the usage is increasing. The energy consumption and emissions of construction machinery will also become the focus of the country's later governance. Various construction machinery manufacturers have been exploring a high-efficiency , Energy-saving and environmentally friendly energy-saving excavators. At present, excavators in the domestic market generally use back pressure to achieve the coordination and softness of excavator movements, but the negative effects it brings are also very large. First, the generation of back pressure consumes a lot of energy and produces waste. ; The second is to make the hydraulic system hydraulic oil temperature rise and...
