Arrangement for controlling rock drilling

Abstract

The present invention relates to the control method of rock drilling, and a rock drilling device. If at least one of the delivery channels (37) of a delivery actuator (3, 33) is provided with a throttle valve (46) and 掘進 speed increases, the flow which pressure declines by this valve and passes along a throttle valve as a result will increase. The increase in pressure difference and 掘進速度 is detected by detecting pressure in the preceding paragraph of a throttle valve, and the latter part of a throttle valve. An increase of a feed rate constitutes the oil pressure system so that blow pressure may be lowered.
