[0002] Internal combustion rock drills are mainly used in defense projects, mine drilling, railway sleeper maintenance, highway crushing, firefighting and earthquake rescue, etc. The internal combustion rock drills on the market use valve-type oil supply. Under the vacuum generated by the engine of the internal combustion rock drill, a certain proportion of gasoline and air are mixed through the valve-type oil supply method, and the corresponding concentration is automatically proportioned according to the different working state requirements of the engine, and the corresponding amount of mixed gas is output to ensure the normal operation of the machine.
[0003] The valve plate type oil supply method has many complex structures installed on the handle body, including a check valve plate, a check gasket, an oil needle assembly, a throttle valve, etc. The check valve plate bounces 3000 times per minute during oil supply, which can easily cause damage to the check valve plate and requires frequent maintenance. In addition, since it is difficult to achieve complete sealing performance, even a new machine leaving the factory needs to be debugged by professionals after a period of use. The structure is complex and technical, and there are very few professional maintenance personnel, resulting in many machines being shelved because they cannot be effectively repaired after a period of use.
[0004] In order to solve the above problems, an independent carburetor is set to supply oil to the machine. This carburetor is easily available on the market and is common to ordinary gasoline engines. It makes the machine easy to repair, easy to start, easy to operate, low maintenance rate, easy maintenance, increased speed, fuel saving and other advantages; but the improved carburetor cannot be reasonably installed on the crankcase of the engine due to changes in parts, and the existing handle body cannot fix the carburetor and the throttle switch, ignition switch, and oil suction and discharge pipes, affecting the upgrading and replacement of the internal combustion rock drill.
