When the drilling rig is controlled to retreat, the hydraulic oil of the clamping component 5 and the chuck component 4 returns through the reversing valve; at this time, the clamping component 5 clamps the drill rod 6, and the chuck component 4 releases the drill rod 6. The controller controls the propulsion cylinder 2 to retreat, and drives the rotating component 3 to retreat, and prepares for the next feed; in this process, the chuck component 4 releases the drill rod 6, and when the rotating component 3 drives the chuck component 4 to retreat, the chuck still rotates with the rotating component 3, while ensuring that the drill rod 6 remains in its original position; in this way, when the drilling rig retreats, the rotating component 3 does not need to stop rotating, and only needs to use the reversing valve to control the clamping and loosening of the chuck component 4 and the clamping component 5, so as to complete the drilling work, which simplifies the drilling operation and improves the drilling efficiency.

[0050] S3, when the drilling rig is feeding, the hydraulic oil flows into the reversing valve, and the hydraulic oil is supplied to the clamping component 5 and the chuck component 4 through the reversing valve at the same time; at this time, the clamping component 5 releases the drill rod 6, and the chuck component 4 clamps the drill rod 6; the controller controls the rotating component 3 to move forward;

[0051] S4, when the drilling rig retreats, the hydraulic oil of the clamping component 5 and the chuck component 4 returns through the reversing valve; at this time, the clamping component 5 clamps the drill rod 6, and the chuck component 4 releases the drill rod 6; the controller controls the rotating component 3 to retreat.

[0052] The control method of the hydraulic rotary drilling rig provided by the present invention is that the rotating component 3 is slidably connected with the machine tool 1, and the chuck component 4 is transmission-connected with the rotating component 3, and the clamping component 5 is fixed on the machine tool 1, and the reversing valve of the control component is connected with the chuck component 4 and the clamping component 5; therefore, when the drilling rig is controlled to feed, the hydraulic oil enters the reversing valve, and the hydraulic oil is supplied to the clamping component 5 and the chuck component 4 at the same time through the reversing valve; at this time, the clamping component 5 releases the drill rod 6, and the chuck component 4 clamps the drill rod 6, and the controller controls the propulsion cylinder 2 to move forward and drives the rotating component 3 to move forward; when the rotating component 3 moves forward, the chuck component 4 clamping the drill rod 6 rotates with the rotating component 3, thereby drilling a hole in the coal seam; when the drilling rig is controlled to retreat, The hydraulic oil of the clamping component 5 and the chuck component 4 returns through the reversing valve; at this time, the clamping component 5 clamps the drill rod 6, the chuck component 4 releases the drill rod 6, the controller controls the propulsion cylinder 2 to retreat, and drives the rotating component 3 to retreat, and prepares for the next feed; in this process, the chuck component 4 releases the drill rod 6, and when the rotating component 3 drives the chuck component 4 to retreat, the chuck still rotates with the rotating component 3, and at the same time ensures that the drill rod 6 remains in the original position; in this way, when the drilling rig retreats, the rotating component 3 does not need to stop rotating, and only needs to use the reversing valve to control the clamping and loosening of the chuck component 4 and the clamping component 5, so as to complete the drilling work, which simplifies the drilling operation and improves the drilling efficiency.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
