[0002] Rock drilling rigs are mainly used in open-pit mining. There are a lot of dust, oil mist, catkins and other debris in the working environment, which are easily accumulated on the surface of the cooler fins along with the cooling air channel and are not easy to clean. In the long run, the holes of the cooler aluminum fins will be blocked, seriously affecting the effect of the machine's own cooling system. As a result, the engine water temperature, air compressor oil temperature, and hydraulic oil temperature are too high and report faults, making the machine unable to operate normally, and even burning the engine and screw machine in severe cases. At present, the traditional method is to wait for the cooler to be blocked, and the operator will flush the cooler with high-pressure water, or at the end of each shift, manually blow the cooler fins with an air gun. Without effective preventive measures, it is extremely inconvenient, time-consuming and labor-intensive, and the effect is not good.

[0003] To this end, the present invention proposes an automatic cleaning system for dust on the surface of a cooler of an open-pit rock drill in a mine, which is a device capable of automatically cleaning debris on the surface of the cooler, effectively preventing the cooler from being blocked and avoiding cooling system failures.
