Fully automatic hydraulic rock opening device

Abstract

The invention relates to a full-automatic hydraulic stone splitting device, and belongs to the technical field of hydraulic devices, and provides a full-automatic hydraulic stone splitting device. The fully-automatic hydraulic stone splitting device has the advantages that the structure is simple, and the convenience in use is realized; by adopting the electrical-mechanical-hydraulic integral design, the time is shortened, the labor intensity is decreased, and the working efficiency is high. The full-automatic hydraulic stone splitting device adopts the technical scheme that the full-automatic hydraulic stone splitting device consists of a stone splitting expander and a stone splitting hydraulic cylinder, wherein a drilling part mainly consists of a hydraulic motor, an impact drill bit and a drilling hydraulic cylinder; the impact drill bit is arranged on the hydraulic motor, and the drilling hydraulic cylinder is used for driving the impact drill bit to move up and down; the stone splitting hydraulic cylinder and the drilling hydraulic cylinder are connected with a main oil pipeline through low-pressure relief valves; the stone splitting expander and the hydraulic motor are connected with the main oil pipeline through high-pressure relief valves; a main overflow valve is arranged on the main oil pipeline, and throttling valves are respectively arranged on oil inlet pipes of the stone splitting hydraulic cylinder, the drilling hydraulic cylinder, a stone splitting arm and the hydraulic motor; electromagnetic reversing valves are respectively arranged on oil inlet and outlet pipelines. The full-automatic hydraulic stone splitting device is widely applied to stone splitting.

Description

Technical field [0001] The invention relates to a fully automatic hydraulic rocking device, belonging to the technical field of hydraulic devices. Background technique [0002] With the rapid development of the national economy and the country's increasing demand for mineral resources, the importance of rock engineering and mining engineering has become increasingly prominent. In traditional rock and mine mining, whether it is open-pit mining or underground mining, the most basic work is to break the rock out of the rock mass. At present, most mining uses methods such as drilling and blasting, concrete expansion and the use of breaking hammers. Considering the development of our country’s economy, environmental protection, and the safety of construction personnel, coupled with the soaring cost of explosives and the troublesome approval procedures for blasting, coupled with the geological hazards caused by blasting methods on the mountain, these The social problems caused by tra...
