[0026] See also Figure 1-6 The utility model provides a technical solution: a combined drill rod for a mining drilling machine, comprising a first drill rod 1, a second drill rod 2 and a drill bit 3, the first drill rod 1 is installed on the top of the second drill rod 2, the drill bit 3 is fixedly connected to the bottom of the second drill rod 2, and a mounting assembly is provided on the first drill rod 1, the mounting assembly comprises a mounting rod 5 and two positioning slide blocks 6, the mounting rod 5 is fixedly connected to the bottom end of the first drill rod 1, the two positioning slide blocks 6 are fixedly connected to the outer surface of the mounting rod 5, a mounting groove 7 is provided on the top of the second drill rod 2, the mounting rod 5 is slidably connected to the mounting groove 7, and the inner wall of the mounting groove 7 is provided with two positioning slide grooves 8 adapted to the positioning slide blocks 6, and the two positioning slide grooves 8 are both "L"-shaped.

[0027] A receiving groove 12 is provided on the outer surface of the second drill rod 2, and two sliding grooves 15 are provided at the bottom of the mounting groove 7. The two sliding grooves 15 are communicated with the inside of the receiving groove 12, and the insides of the two sliding grooves 15 are slidably connected to the limit plates 9. The inside of the receiving groove 12 is slidably connected to the connecting plate 13, and the bottom ends of the two limit plates 9 are fixedly connected to the top of the connecting plate 13. The bottom of the connecting plate 13 is fixedly connected to two springs 10, and the bottom ends of the two springs 10 are fixedly connected to the inner bottom wall of the receiving groove 12.

[0028] Rotation grooves 16 are provided on both sides of the inner wall of the storage groove 12, and the interiors of the two rotation grooves 16 are rotatably connected with the rotation shafts 11, and the opposite surfaces of the two rotation shafts 11 are fixedly connected with the sealing plates 4, and the outer surfaces of the two rotation shafts 11 are sleeved with torsion springs 14, one end of the two torsion springs 14 is fixedly connected to the corresponding rotation shafts 11, and the ends of the two torsion springs 14 away from the corresponding rotation shafts 11 are fixedly connected to the inner walls of the corresponding rotation grooves 16.

[0029] Furthermore, when using the device, when installing the first drill rod 1 and the second drill rod 2, the user plugs the mounting rod 5 on the first drill rod 1 into the mounting groove 7 on the second drill rod 2, and at the same time, the two positioning slide blocks 6 correspond to the corresponding positioning slide grooves 8, so as to facilitate the insertion of the mounting rod 5 into the mounting groove 7. When the two positioning slide blocks 6 slide vertically in the corresponding positioning slide grooves 8, the corresponding limit plates 9 are squeezed, so that the two limit plates 9 drive the connecting plate 13 to move downward under the guidance of the storage groove 12. The downward movement of the connecting plate 13 compresses the corresponding spring 10. Then, when the mounting rod 5 contacts the inner bottom wall of the mounting groove 7, the user rotates the first The drill rod 1 makes the two positioning slide blocks 6 slide horizontally in the corresponding positioning slide grooves 8, thereby limiting the installation rod 5. When the two positioning slide blocks 6 slide to the limit position, the two limit plates 9 will be reset under the action of the two springs 10, thereby limiting and fixing the two positioning slide blocks 6. When the first drill rod 1 and the second drill rod 2 need to be removed, the user will pull the sealing plate 4, and the sealing plate 4 will drive the two rotating shafts 11 to rotate. The rotation of the two rotating shafts 11 will drive the corresponding torsion springs 14 to store force. After opening the sealing plate 4, the user will push the connecting plate 13 down, so that the connecting plate 13 drives the two limit plates 9 to move downward, thereby releasing the limit on the two positioning slide blocks 6.

[0030] Through the cooperation of the mounting rod 5, two positioning slide blocks 6, two limit plates 9, the connecting plate 13 and two springs 10, the two positioning slide blocks 6 can limit the mounting rod 5 after sliding horizontally in the corresponding positioning slide grooves 8, and the two limit plates 9 will be reset under the action of the two springs 10, thereby facilitating the limiting and fixing of the two positioning slide blocks 6, so that the first drill rod 1 and the second drill rod 2 can be quickly connected and installed without replacing the entire drill rod, thereby solving the problem that the drill rod with an integral structure is inconvenient to transport and further improving the practicality of the mining drill rod.

[0031] Through the cooperation of the sealing plate 4, the two torsion springs 14 and the two rotating shafts 11, the sealing plate 4 can prevent dust from entering the storage groove 12 when the drill rod is drilling when closed, and the two torsion springs 14 can make the sealing plate 4 more stable when closed, thereby improving the practical effect of the installation structure when in use.

[0032] Working principle: when installing the first drill rod 1 and the second drill rod 2, the user plugs the mounting rod 5 on the first drill rod 1 into the mounting groove 7 on the second drill rod 2, and at the same time, the two positioning slide blocks 6 correspond to the corresponding positioning slide grooves 8, so as to facilitate the insertion of the mounting rod 5 into the mounting groove 7. When the two positioning slide blocks 6 slide vertically in the corresponding positioning slide grooves 8, the corresponding limit plates 9 will be squeezed, so that the two limit plates 9 will drive the connecting plate 13 to move downward under the guidance of the storage groove 12. The downward movement of the connecting plate 13 will compress the corresponding spring 10. Subsequently, when the mounting rod 5 contacts the inner bottom wall of the mounting groove 7, the user rotates the first drill rod 1 so that the two positioning slide blocks 6 slide horizontally in the corresponding positioning slide grooves 8, thereby limiting the mounting rod 5. When the two positioning slide blocks 6 slide to the limit position, the two limit plates 9 will be reset under the action of the two springs 10, thereby limiting and fixing the two positioning slide blocks 6.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
