Problems solved by technology
[0004] The oil tank of the lubricator is provided with an oil inlet for adding lubricating oil into it, and the oil inlet is provided with an oil cover. Since the oil tank is under high pressure for a long time when the oil injector is in use, and the oil cover has low pressure resistance, Long-term use will cause damage to the oil cap or leakage
Moreover, the oil valve of the existing oil injector is also in a high-pressure state for a long time and is used frequently, so the failure rate of the oil valve is also very high
Moreover, it is difficult to accurately adjust the oil injection volume of the existing oil injector that fully adopts pressure injection, which may cause insufficient or excessive waste of oil
Therefore, there are still many imperfections in the prior art of rock drilling machine oiler

Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] Such as figure 1 Shown, the present invention is implemented like this:
[0019] In the initial state, the valve 3 on the pressure pipe 2 connecting the oil tank 4 and the air pipe 1 is closed, and there is no high-pressure air flow in the pressure pipe 2 . Oil is supplied to the oil tank 4 through the oil filling port 8 of the oil tank 4 . The adjusting bolt 7 on the oil tank 4 is in a tightened state, and the pressure plate 6 presses the through hole 5 tightly, and the through hole 5 is closed. When in use, first adopt the method of no-pressure oil seepage, loosen the adjusting bolt 7, so that the pressure plate 6 in the oil tank 4 no longer presses tightly against the pipe wall of the air duct 1 where the through hole 5 is located, so that the through hole 5 is Make the oil tank 4 communicate with the inner cavity of the air duct ...

The invention discloses a method and device for gadder oil injection. Pressure oil injection and non-pressure oil leakage are combined, at least one through hole (5) through which an oil tank (4) is communicated with an air pipe (1) is formed in the pipe wall of the air pipe (1) inside the oil tank (4), and at least one pressing plate (6) capable of pressing or loosening the air pipe (1) wall in which the through hole (5) is formed is arranged in the oil tank (4). Due to the fact that the pressing plate (6) presses or loosens the through hole (5), the oil inlet volume can be effectively adjusted, the oil tank (4) is prevented from being in a high-pressure state for long time, an oil cover can be protected, and an equipment failure rate is reduced. The method and device are simple, practical, safe, effective and worth popularizing, and not too much investment is needed.
Description
technical field [0001] The invention relates to an oil injection method and device, in particular to an oil injection method and device for rock drilling machines. Background technique [0002] A rock drill is a tool used to directly mine stone. It drills blastholes in the rock formation, so that explosives can be put in to blast the rocks, so as to complete the mining of stones or other stone works. The rock drill works on the principle of impact crushing. When working, the piston makes high-frequency reciprocating motion and continuously impacts the shank. Under the action of the impact force, the sharp wedge-shaped drill bit crushes the rock and cuts into a certain depth, forming a dent. After the piston retreats, the drill bit turns a certain angle, the piston moves forward, and when it hits the drill tail again, a new dent is formed. The fan-shaped rock block between the two dents is sheared by the horizontal component force generated by the drill bit. The piston c...
