[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] like Figure 1-3 As shown, an automatic rod connecting device is installed on a coal drilling rig and used together with the coal drilling rig. The coal drilling rig includes a mast 200, a motor 400 and a drill rod 300. The mast 200 provides a guide for the drill rod 300, and the motor 400 provides power for the drill rod 300. The motor 400 can move along the mast 200, and the motor 400 is connected to the drill rod 300 by means of a latch. The automatic rod connecting device includes a connecting seat 101, a horizontal push cylinder 102, a movable rod 103, a support seat 104 and a compensation Cylinder; a mounting plate is provided at one end of the connecting seat 101, and a plurality of screw holes are provided on the mounting plate, and the connecting seat 101 is fixedly connected to the side wall of the mast 200 by screws; a mounting cavity is provided on the connecting seat 101, and the push cylinder 102 is fixedly connected in the mounting cavity; the compensating cylinder is fixedly connected to the mast; a guide groove is provided on the connecting seat 101, and a movable rod 103 is inserted into the guide groove, and the movable rod 103 is connected to the piston rod of the push cylinder 102; a connecting frame is provided on the movable rod 103, and the support seat 104 is rotatably connected to the movable rod 103 through the connecting frame.

[0034] Specifically, the connecting frame includes a first connecting plate and a connecting shaft, a second connecting plate is provided on the bottom surface of the support seat 104, the first connecting plate is provided with a first connecting hole corresponding to the connecting shaft, and the second connecting plate is provided with a second connecting hole corresponding to the connecting shaft; a connecting block is provided on the first connecting plate, the connecting block is fixedly connected to the movable rod 103, and a movable groove for the connecting block to move is provided on the connecting seat 101.

[0035] The support seat 104 is an arc-shaped support plate, and the spare drill rod 300 is located on the support seat 104, providing a stable support force for the drill rod 300 to prevent the drill rod 300 from rolling off the support seat 104; the support seat 104 is at one end of the movable rod 103, and at the same time, one end of the connecting seat 101 is bent upward, and the guide groove is at the end of the connecting seat 101 that is bent upward, so that the support seat 104 is above the mast 200, and the support seat 104 will not collide with the mast 200 when moving toward the mast 200.

[0036] The movable rod 103 is a hollow structure, which increases the structural strength of the movable rod 103.

[0037] During drilling operation, the motor 400 drives the drill rod 300 to rotate, and the drill rod 300 drills into the coal seam to mine coal. When the drill rod 300 completely enters the soil layer, the motor 400 stops working, and the pin is pulled out from the output shaft of the motor 400 and the drill rod 300, and the motor 400 is disconnected from the drill rod 300.

[0038] After the motor 400 moves along the mast 200 to the top of the mast 200, the push cylinder 102 drives the movable rod 103 to move, and the movable rod 103 drives the drill rod 300 on the support seat 104 to move onto the mast 200. After the new drill rod 300 moves to the same straight line as the old drill rod 300, the new drill rod is at one end of the compensation cylinder, and the compensation cylinder pushes the new drill rod to move downward, and the new drill rod forms a preliminary connection with the old rotating rod. Subsequently, the motor 400 moves so that the output shaft contacts the new drill rod 300, and the pin is inserted so that the output shaft of the motor 400 is connected to the new drill rod 300. The motor 400 drives the new drill rod 300 to move downward, and the new drill rod 300 is also connected to the old drill rod 300 through the pin, extending the length of the drill rod 300, so that the drilling operation continues to be carried out to penetrate deeper rock formations; the installation of the drill rod 300 is completed quickly, and the operation efficiency is improved.

[0039] By utilizing the automatic rod connecting device, the length of the mast 200 is controlled, so that the drilling rig is more stable during use, but the drilling depth of the drilling rig is not affected, thereby improving the practicality of the drilling rig.

[0040] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned utility model concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) to form a technical solution.
