が生ずる。Conventional technology: A control device that controls the prime mover to rotate at high speed or low speed depending on whether the hydraulic rock drill is operating with impact or other operations is known in Patent Application Publication No. 57-49036. It is.
The above-mentioned prime mover rotation control device is suitable for a rock drill that is not equipped with a compressor for blowing during drilling, which requires low-speed rotation at all times except during operations involving impact. However, recently, a rock drill equipped with a compressor for blowing during drilling has appeared, and in this rock drilling machine, the hydraulic pump for sending pressure oil to the hydraulically operated valve that operates the striking device and the compressor for blowing during drilling are operated by a single prime mover. It is something that will be done. Moreover, the compressor for blowing during drilling is required to operate not only when the rock drill is operated with impact, but also during drilling operations that do not involve impact, such as hole cleaning. In other words, compressed air from the compressor for blowing during drilling is indispensable for the drilling work of rock drilling machines, regardless of impact, rotation, feeding, or hole cleaning.
Moreover, the compressor for blowing during drilling requires the largest output, and therefore, high-speed rotation of the prime mover is required during the above-mentioned work. When the above-mentioned known rotation control device of the prime mover is attached to the above-mentioned rock drill with a compressor for blowing during drilling, the rotation control device rotates the prime mover at low speed at all times except during impact, so it is difficult to perform hole cleaning, etc. During drilling work that does not involve impact, the prime mover rotates at a low speed, and the amount of compressed air discharged by the compressor for blowing during drilling decreases, resulting in a decrease in discharge pressure, which increases the amount of chips remaining after drilling, and reduces drilling efficiency. This results in disadvantages such as a decrease in the depth of the hole and the inability to drill deep holes.
