The cleaning component is mainly used to assist in cleaning the rock debris generated by blasting and charging grooving. This design not only reduces the cleaning burden of the staff, but also improves the cleanliness of the working environment, further improving work efficiency.

[0023] In a further preferred embodiment of the utility model, the cleaning assembly includes a fixed cylinder 6, a limiting cylinder 7, a metal tube 16, a fan 11, a dust collecting piece 12 and a connecting hose 13, the fixed cylinder 6 is detachably mounted on the output shaft of the rock drill body 1, the limiting cylinder 7 is rotatably mounted on the fixed cylinder 6, the metal tube 16 is fixed on the fixed cylinder 6 and is rotatably connected to the limiting cylinder 7, the fan 11 is fixedly mounted on the top of the base 5, the dust collecting piece 12 is fixedly mounted on the outer wall of the cylinder 4, the dust collecting piece 12 is fixedly connected to the air inlet end of the fan 11, and the connecting hose 13 is fixedly mounted on the dust collecting piece 12 and extends into the limiting cylinder 7.

[0024] In this embodiment, the fixed cylinder 6 is designed to be detachably mounted on the output shaft of the rock drill body 1. This design makes the replacement and maintenance of the fixed cylinder 6 more convenient. The metal tube 16 can effectively guide and transport the rock fragments without affecting the rotation of the limiting cylinder 7. The fan 11 serves as the power source of the cleaning component. The airflow it generates can effectively drive the flow of rock fragments. The airflow generated by the fan 11 can enter the interior of the limiting cylinder 7 through the connecting hose 13, suck in the rock fragments and transport them to the dust collecting part 12.

[0025] In a further preferred embodiment of the utility model, the chisel head 8 is provided with a plurality of dust suction holes, the metal pipe 16 is provided with a discharge port, and a flange 17 is fixedly installed on one side of the metal pipe 16 and the chisel head 8 close to each other, and the two flanges 17 are connected by fixing bolts.

[0026] In this embodiment, when the rock drill body 1 is working, the dust suction hole can suck in the generated rock debris in time to prevent it from scattering in the working area, thereby keeping the working environment clean and tidy. The setting of the dust suction hole enables the chisel head 8 to not only have the function of drilling holes, but also has the function of dust suction, realizing the integration of functions. The discharge port is connected with the dust suction hole to form an unobstructed passage, so that the rock debris sucked in by the dust suction hole can be smoothly discharged through the metal pipe 16.
