The shank rod of a hydraulic rock drill is equipped with a torque transmission mechanism such as a spline latch, which transmits torque to the drill bit during drilling and also allows the shank rod to move in the axial direction for crushing rock by impact force. . Here, the torque and impact force applied to the drill bit must be applied in an impact manner through this torque transmission mechanism, and a large surface pressure is generated on the torque transmission portion such as the sliding surface of the spline. Therefore, in order to prevent seizure and wear of the torque transmitting part due to this surface pressure as much as possible, it is essential to lubricate the shunt rod part with oil.

好ましくないという問題があつた。 Therefore, when replenishing oil to the oil sump 14, if it is equipped with a filler cap, remove the filler cap,
If there is no filler cap, the oil sump 14 itself is removed and lubricated with an oil shovel, but it is troublesome to do this once a day, and moreover, it often gets contaminated with dirt, which can cause the lubricator 1 to malfunction. It often happens. On the other hand, oil sump 14
Lengthening the interval between oil refills by increasing the capacity of
There is a problem in that the oil reservoir 14 becomes extremely expensive after a capacity of 1, which is not desirable.

In order to solve the above problems, in this invention, an oil reservoir of a predetermined capacity is attached to the lubricator that supplies mist oil to the shank rod part of the shank rod lubrication device of a hydraulic rock drill mounted on a truck. An oil supply pipe was connected to this oil reservoir via a check valve from the hydraulic oil return circuit of the truck.

During drilling work, oil mist is supplied from the lubricator to the shank rod of the hydraulic rock drill, but the oil mist is not supplied during incidental work such as disconnecting and connecting the rod during drilling. is temporarily suspended. At this time, oil is automatically replenished into the oil reservoir from the oil supply pipe due to the back pressure of the hydraulic oil return circuit of the truck.

る。 During drilling work, when the air tank 17 is opened, compressed air is sent from the pressurized air source 2 to the lubricator 1,
The lubricator 1 supplies mist-like oil to the shank rod portion 5 of the rock drill 4 to lubricate the shank rod portion 5. When the air tank 17 is closed during incidental work such as disconnecting and connecting the rod during drilling, the supply of mist oil is temporarily stopped. At this time, in the oil reservoir 14 of the lubricator 1,
Oil is automatically replenished from the oil supply pipe 16 to a predetermined level by the back pressure of the hydraulic oil return circuit 11 of the truck. If the oil reservoir 14 is one that can be refilled with oil at a low pressure of about 0.7 kgf/ cm2 , the hydraulic oil return circuit 11
Since the back pressure is generally 1 to 2 Kgf/cm 2 , oil can be replenished without the need for a pump or the like.
