Hydraulic feeding device for rock crushing hydraulic jack having remote adjustment

摘要

The present invention relates to a hydraulic feeding device for a remotely controlled bedrock breakage hydraulic jack, which comprises: a direction switching valve controlling flow of high-pressure operating oil and low-pressure operating oil to wirelessly and remotely control operation of the hydraulic feeding device that provides a hydraulic force to the hydraulic jack for bedrock breakage; and a wireless remote control means wirelessly controlling the direction switching valve. Accordingly, operation efficiency can be increased, and bedrock breakage can be performed by one worker to increase economic feasibility.
