At the same time, the tripod 404 rotates and adjusts its angle as the angle of the mast 401 changes, thereby providing a good support effect for the mast 401 and ensuring the normal progress of the drilling operation.

[0057] The mast cylinder is used to erect or lower the mast and adjust the working angle of the mast so that it can work at a variety of angles; specifically, when the mining machine moves, the mast cylinder drives the mast to rotate, so that the mast flips to a horizontal state, facilitating the normal movement of the mining machine; the luffing cylinder is used to adjust the distance between the mast and the center of the chassis in the working device, making it convenient to quickly find a new working point without moving the drilling rig, reducing the shaking of the mast during operation, and increasing the working stability of the mining machine.

[0058] The mast 401 assembly provides support force for the driving power head assembly 500, the screw rod 600, and the automatic connecting rod device.

[0060] The driving power head assembly 500 provides power for the cutting and drilling of the spiral rod 600 .

[0061] The connecting device includes a male connector 801 and a female connector 807, which are respectively arranged at the two ends of the spiral rod 600. A connecting rod 806 is arranged at one end of the male connector 801, and a connecting groove 811 corresponding to the connecting rod 806 is arranged on the female connector 807; a plurality of first hooks are arranged on the side wall of the male connector 801, and a plurality of second hooks are arranged on the side wall of the female connector 807, and the number of the second hooks is the same as the number of the first hooks; the first hook includes a connecting ring 802, a first vertical section 803, a first horizontal section 804 and a second vertical section 816. The straight section 805, the first vertical section 803 and the second vertical section 805 are respectively arranged at the two ends of the first horizontal section 804, and the first vertical section 803 is used to connect the connecting ring 802 and the first horizontal section 804; the second hook is arranged at the top of the side wall of the connecting groove 811, and the second hook includes the third vertical section 808, the second horizontal section 809 and the fourth vertical section 810. The third vertical section 808 and the fourth vertical section 810 are respectively arranged at the two ends of the second horizontal section 809, and the third vertical section 808 is used to connect the female connector 807 and the second horizontal section 809.

[0062] The distance between adjacent first hooks is greater than the width of the second hooks, and the distance between adjacent second hooks is greater than the width of the first hooks; the distance between the first horizontal segment 804 and the connecting ring 802 is greater than the sum of the length of the fourth vertical segment 810 and the width of the second horizontal segment 809, and the distance between the second horizontal segment 809 and the top surface of the connecting groove 811 is greater than the sum of the length of the second vertical segment 805 and the width of the first horizontal segment 804; the distance between the first vertical segment 803 and the second vertical segment 805 corresponds to the width of the fourth vertical segment 810, and the distance between the third vertical segment 808 and the fourth vertical segment 810 corresponds to the width of the second vertical segment 805.

[0063] Preferably, three first hooks are provided, and three second hooks are provided, the three first hooks are provided on the male connector 801 at intervals of 120°, and the three second hooks are provided on the female connector 807 at intervals of 120°.

[0064] When connecting two spiral rods 600, the male connector 801 on one spiral rod 600 is connected to the female connector 807 of the other spiral rod 600, the connecting rod 806 on the male connector 801 is inserted into the connecting groove 811 on the female connector 807, the first hook is inserted between two adjacent second hooks, and the second hook is inserted between two adjacent first hooks. Then, one of the spiral rods 600 is rotated relative to the other spiral rod 600, and the second vertical section 805 moves to the third vertical section 808, and the spiral rod 600 at the upper end is lifted up. The second vertical section 805 is embedded in the groove between the third vertical section 808 and the fourth vertical section 810, and the fourth vertical section 810 is embedded in the groove between the first vertical section 803 and the second vertical section 805, thereby completing the connection of the two spiral rods 600.

[0065] Since the power head motor drives the spiral rod 600 to rotate in the same direction during the drilling operation, the second vertical section 805 will always be against the third vertical section 808, and the first vertical section 803 will always be against the fourth vertical section 810. Therefore, the male connector 801 and the female connector 807 can achieve a stable connection during the hole rotation operation and will not be separated, thereby improving the safety of the operation. At the same time, the connection device is used to quickly form the connection between the two spiral rods 600, simplifying the spiral rod 600 connection process and improving the efficiency of the drilling operation.

[0066] A male connector 801 is provided on the output shaft of the power head motor, and the screw rod 600 is connected to the output shaft of the power head motor by means of a male and female connector 807, so that the screw rod 600 can quickly form a connection with the driving power head assembly to provide power for the screw rod 600.

When the support seat 704 moves toward the mast 401, it will not collide with the mast 401.

[0068] During drilling operations, the power head motor drives the screw rod 600 to rotate, and the screw rod 600 drills into the coal seam for coal mining. When the screw rod 600 completely enters the soil layer, the power head motor stops working, and the mounting frame drives the power head motor to move toward the screw rod 600. The second vertical section 805 is disengaged from the groove between the third vertical section 808 and the fourth vertical section 810, and the fourth vertical section 810 is disengaged from the groove between the first vertical section 803 and the second vertical section 805. The power head motor rotates in the opposite direction for a short distance, and the first hook moves to the gap between the two second hooks, and the second hook moves to the gap between the two first hooks. The propulsion motor drives the mounting frame to lift, that is, the mounting frame moves to the top of the mast 401, and the output shaft of the power head motor is disconnected from the screw rod 600.
