[0002] When the existing rotary drilling rig is in operation, the rotary drilling rig of the rotary drilling rig utilizes the rotational force to rotate and shovel the soil into the drill barrel through the drill bit at the bottom thereof. After working for a period of time, the drill bit is lifted to the ground level and the drill bit at the bottom is loosened. The soil in the rotary drilling rig needs to be cleaned out during cleaning. For example, a noise reduction and soil unloading mechanism of a rotary drilling rig disclosed in patent number CN202310258065.5 is connected to a soil unloading push plate arranged in the drill barrel through the output end of the hydraulic cylinder, and the soil unloading push plate is driven to rise and fall in the drill barrel by the hydraulic cylinder to achieve the function of unloading soil.

[0003] However, since the output end of the hydraulic cylinder is directly connected to the soil-discharging push plate during the operation of the rotary drilling rig, the soil in the rotary drilling barrel will adhere to the output end of the hydraulic cylinder during the rotary drilling process, so that when the hydraulic cylinder drives the soil-discharging push plate to its original position, the soil will be brought into the hydraulic cylinder, causing damage to the hydraulic cylinder.
