Abstract

The invention discloses a digging device with a rapid start function. The digging device comprises a digging machine and an engine connected with the digging machine. The engine is used for driving the digging machine. The engine comprises a power part, an oil spraying system and a hydraulic part. The hydraulic part comprises a compression cavity, a pump cavity, a return cavity and a hydraulic loop. The compression cavity is formed in the rear portion of the engine and provided with a first oil opening and a second oil opening which are connected with a compression energy accumulator through a first control valve and a second control valve respectively. The pump cavity is connected with a low-pressure oil way and a high-pressure oil way through a check valve respectively. A return control valve and a low-pressure energy accumulator are arranged on a low-pressure oil way. A pressure reduction valve is arranged on an oil pipeline between a high-pressure energy accumulator and a cylinder body. A start valve is arranged on an oil pipeline between the compression energy accumulator and the high-pressure energy accumulator. The digging device is simple in structure, convenient to manufacture, high in scavenging efficiency, stable in performance and large in output torque, and a complete control system and a position detecting system are designed.

Description

technical field [0001] The invention relates to the field of excavating machinery, in particular to an excavating device with a quick start function. Background technique [0002] An excavator, also known as an excavator, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. [0003] How to further reduce the working energy consumption of the excavating device and improve the efficiency is a problem that people have been concerned about. A large part of today's large excavators is driven by engines, and existing eng...
