To this end, a double layer propulsion mechanism is provided to meet the above-mentioned operational requirements. However, the double-layer propulsion mechanism in the related art drives the drilling machine to move by driving the steel wire rope assembly through the oil cylinder, and the steel wire rope assembly comprises a steel wire rope, a pulley block, a steel wire rope fixing structure and the like, so that the double-layer propulsion mechanism is complex in structure and inconvenient to manufacture and maintain, and meanwhile, the oil cylinder occupies a large space due to expansion and contraction, so that the application range of the propulsion mechanism is limited.

The deep hole drilling operation is completed in a circulating mode.

When a shallow hole needs to be drilled, the rod part of the hydraulic cylinder retracts, and the first carriage 110 is driven to move towards the direction close to the second carriage 120, for example, the first carriage 110 and the second carriage 120 are folded. It can be understood that, at this time, the drill rod has been assembled, and is inserted into the follow-up drill rod supporter 150 and the fixed drill rod supporter 160, and is supported by the follow-up drill rod supporter 150 and the fixed drill rod supporter 160. In operation, the motor assembly 190 drives the sprocket assembly 140 to drive the mounting base 130 and the drilling machine 180 to advance forward for drilling. When the drill rod needs to be withdrawn after the drilling is finished, the motor assembly 190 drives the chain wheel assembly 140 to drive the mounting seat 130 and the drilling machine 180 to be withdrawn to the rearmost end, and the drill rod withdrawal is finished. And the shallow hole drilling operation is completed in a circulating mode.

When the roof bolt needs to be knocked down, the rod part of the hydraulic cylinder is completely retracted, and the first carriage 110 is driven to move towards the direction close to the second carriage 120, such as the first carriage 110 and the second carriage 120 are closed. Then, the position of the second carriage 120 is adjusted by rotating the arm support, so that the second carriage 120 stands up. When the assembly of the drill rod is completed and the drill rod is supported by the follow-up drill rod supporter 150 and the fixed drill rod supporter 160, the operation is started, and the motor assembly 190 drives the chain wheel assembly 140 to drive the mounting seat 130 and the drilling machine 180 to advance forward for drilling. When the drill rod needs to be withdrawn after the drilling is finished, the motor assembly 190 drives the chain wheel assembly 140 to drive the mounting seat 130 and the drilling machine 180 to be withdrawn to the rearmost end, and the drill rod withdrawal is finished. And the shallow hole drilling operation is completed in a circulating mode.
