Abstract

The invention discloses an electro-hydraulic vibration excitation system for portable type rock drilling and stone crushing equipment. The electro-hydraulic vibration excitation system comprises a manipulator and an electro-hydraulic vibrator mounted on the manipulator; the electro-hydraulic vibrator comprises a hydraulic cylinder, a piston rod, an electric control rotary valve, a hydraulic pump,an oil tank and an overflow valve; the piston rod is provided with a piston, the piston is slidably arranged in a piston cavity in the hydraulic cylinder, and the piston cavity is divided into a hydraulic cylinder upper cavity and a hydraulic cylinder lower cavity through the piston; and a drilling bit is arranged at the head end of the piston rod, a two-position four-way rotary valve serves as the electric control rotary valve and comprises a directional control opening A, an oil return opening T and a pressure oil opening P, and when a valve core of the two-position four-way rotary valve isdriven by a rotary valve motor to run, the pressure oil opening P and the oil return opening T are alternately connected with the directional control opening A in a conducting mode, so that the pistonrod is driven to conduct reciprocating movement in the hydraulic cylinder. The electro-hydraulic vibration excitation system has the advantages of easy realization of high frequency, large flow, simple structure and convenient carrying.

Description

technical field [0001] The invention relates to the field of electro-hydraulic excitation equipment, in particular to an electro-hydraulic excitation system of portable rock drilling and crushing equipment. Background technique [0002] A rock drill is a tool used to directly mine stone. It drills blastholes in the rock formation, so that explosives can be put in to blast the rocks, so as to complete the mining of stones or other stone works. Existing rock drills can be divided into four classes such as pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills by its power source. But its bulky, not conducive to portability. Therefore, it is necessary to improve this. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide an electro-hydraulic excitation system for portable rock drilling and crushing equipment that is easy to realize high frequency, large...
