Hydraulic linkage mechanical hole forming and punching system

The utility model discloses a hydraulic linkage mechanical hole forming and punching system which comprises a crawler-type drilling machine, a drilling rod is arranged on the crawler-type drilling machine, the drilling rod is communicated with a crawler-type clear water pump station, a hole expanding mechanism is arranged on the drilling rod, and the hole expanding mechanism is connected with a drill bit. The crawler-type clear water pump station is communicated with the reaming mechanism through the drill rod, and the reaming mechanism is communicated with the drill bit. The crawler-type clean water pump station synchronously follows the drilling machine to advance, the device is suitable for the coal mine underground operation environment, and meanwhile the reaming mechanism is matched with the drill bit to achieve normal hydraulic coal breaking under the action of low-pressure water; under the high-pressure water mode, a cutting knife in the reaming mechanism expands outwards under the impact of high-press
