[0022] In this embodiment, the output shaft of the first hydraulic telescopic rod 301 drives the support plate 302 to move downward, so that the support plate 302 supports the machine body 1 and can adjust the posture of the machine body 1.

[0023] Specifically, the expansion mechanism 8 includes a mounting box 801, a quick connector 802, a mechanical seal 803, a second hydraulic telescopic rod 804, a through hole 805, and a cutting tooth head 806. The mounting box 801 is mounted on the left side of the robotic arm. The quick connector 802 is mounted on the right side wall of the mounting box 801 near the lower side. The second hydraulic telescopic rod 804 is mounted between the front and rear side walls of the mounting box 801 through the mechanical seal 803, and the second hydraulic telescopic rod 804 is fixedly connected to the tunneling head assembly 7. The second hydraulic telescopic rod 804 is located inside the mounting box 801 and has a through hole 805. The cutting tooth head 806 is mounted on the output shaft of the second hydraulic telescopic rod 804.

[0024] In this embodiment, the quick connector 802 is connected to the hydraulic oil pump through a pipeline, and hydraulic oil is injected into the mounting box 801. The hydraulic oil flows into the second hydraulic telescopic rod 804 through the through hole 805, causing the output shaft of the second hydraulic telescopic rod 804 to drive the cutting tooth head 806 to move back and forth. The second hydraulic telescopic rod 804 rotates with the tunneling head assembly 7, causing the second hydraulic telescopic rod 804 to drive the cutting tooth head 806 to rotate. The side of the mounting box 801 is in close contact with the tunneling head assembly 7 and will not hinder the rotation of the tunneling head assembly 7.

[0025] Specifically, a concave groove 12 is provided on the cutting tooth head 806 at a position corresponding to the second hydraulic telescopic rod 804 for the passage of the second hydraulic telescopic rod 804.

[0026] In this embodiment, the concave groove 12 satisfies the effect of the second hydraulic telescopic rod 804 retracting into the cutting tooth head 806.

[0027] Specifically, the drive mechanism 10 includes a rectangular box 101, a bearing assembly 102, a ball screw 103, a drive motor 104, a ball nut 105, and a sliding sleeve 106. The rectangular box 101 is mounted on the upper surface of the output shaft of the rotary cylinder 9. The front and rear sides of the rectangular box 101 are open. The ball screw 103 is mounted between the left and right side walls of the rectangular box 101 through the bearing assembly 102. The right side of the ball screw 103 is fixedly connected to the output shaft of the drive motor 104. The drive motor 104 is fixedly mounted on the right side of the rectangular box 101. A ball nut 105 is provided on the ball screw 103. A sliding sleeve 106 is fixedly mounted between the front and rear sides of the ball nut 105. The sliding sleeve 106 is sleeved on the upper surface and the outer sides of the front and rear sides of the rectangular box 101.

[0028] In this embodiment, the drive motor 104 drives the ball screw 103 to rotate in the left and right bearing assemblies 102, causing the ball screw 103 to rotate and drive the ball nut 105 to move left and right. The ball nut 105 drives the sliding sleeve 106 to move left and right along the rectangular box 101, thereby achieving the effect of adjusting the left and right position of the drilling mechanism 11.

[0029] Specifically, the drilling mechanism 11 includes a servo motor 111, a drill rod 112, a drill bit 113, and a guide sleeve 114. The servo motor 111 is mounted on the upper surface of the sliding sleeve 106. The left side of the output shaft of the servo motor 111 is fixedly mounted on the drill rod 112. The drill bit 113 is fixedly mounted on the left side of the drill rod 112. The guide sleeve 114 is fixedly mounted on the left edge of the upper surface of the rectangular box 101, and the guide sleeve 114 is movably sleeved on the outside of the drill rod 112.

[0030] In this embodiment, the servo motor 111 drives the drill rod 112 to rotate, the drill rod 112 drives the drill bit 113 to rotate, the drill bit 113 performs water exploration drilling on the coal seam, and at the same time the guide sleeve 114 guides the drill rod 112 to move left and right.

[0031] In use, the output shaft of the first hydraulic telescopic rod 301 in the four support mechanisms 3 drives the support plate 302 to move downward, so that the support plate 302 supports the machine body 1, which can adjust the posture of the machine body 1. In complex geological conditions, the height of the track assembly 2 can be increased to lay anti-slip material, so as to achieve the purpose of the equipment escaping from sinking. The quick connector 802 in the extension mechanism 8 is connected to the hydraulic oil pump through the pipeline, and the hydraulic oil is injected into the mounting box 801, so that the hydraulic oil flows into the second hydraulic telescopic rod 804 through the through hole 805. The output shaft of the second hydraulic telescopic rod 804 drives the cutting tooth head 806 to move back and forth. The second hydraulic telescopic rod 804 rotates with the tunneling head assembly 7, so that the second hydraulic telescopic rod 804 drives the cutting tooth head 806 to rotate. The overall width of the tunneling head assembly 7 can be adjusted according to the usage requirements to meet the needs. To meet various width requirements and facilitate subsequent machine withdrawal, when water exploration drilling is needed in the coal seam, the output shaft of the rotary cylinder 9 drives the rectangular box 101 in the drive mechanism 10 to rotate, adjusting the orientation of the drilling mechanism 11. After adjustment, in the drilling mechanism 11, the servo motor 111 drives the drill rod 112 to rotate, the drill rod 112 drives the drill bit 113 to rotate, and then the drive motor 104 drives the ball screw 103 to rotate in the left and right bearing assemblies 102. The rotation of the ball screw 103 drives the ball nut 105 to move to the left, the ball nut 105 drives the sliding sleeve 106 to move to the left along the rectangular box 101, and the sliding sleeve 106 drives the servo motor 111, the drill rod 112 and the drill bit 113 to move to the left. This can detect whether there is water in the coal seam without the need for a separate water exploration drill or moving the machine body 1, greatly improving the efficiency of tunneling.

[0032] In summary, this rapid coal seam tunneling equipment enhances the attitude adjustment function of the machine body 1. When encountering complex geological conditions, the height of the track assembly 2 can be increased to lay anti-slip material, thereby achieving the purpose of the equipment escaping subsidence. The width of the tunneling head can be adjusted according to usage requirements, which also facilitates subsequent machine withdrawal. The addition of water detection function greatly improves the tunneling efficiency.
