Latest Patents
Shiihara holds a patent for a hydraulic control system designed for a rock drill. This invention focuses on controlling the striking, rotating, and advancing movements of a drilling rod. The system includes a forward feeding conduit for a feed actuator, which is equipped with a relief valve. This valve responds to the pressure in the positive rotating conduit for a rotary actuator, allowing for the pressure in the forward feeding conduit to be relieved. This feature weakens the advancing force when the load on the rotary actuator increases. Additionally, a further relief valve is provided to relieve pressure in the striker conduit, thereby weakening the striking force. Shiihara's patent represents a significant advancement in rock drilling technology.
