[0020] See also Figure 1-5 , an embodiment provided by the utility model:
[0021] A cutting machine based on the connecting channel mining method for excavation: comprising tunnel 1 and tunnel 2 11, and rock 12 to be excavated between tunnel 1 and tunnel 2 11; a cutting device 2 is provided on the surface of tunnel 1; the cutting device 2 comprises a support frame 21, the support frame 21 is fixedly mounted on the surface of tunnel 1; a first motor 22 is fixedly connected to the surface of the support frame 21; a screw rod 23 is fixedly connected to the output shaft of the first motor 22; the first motor 22 drives the screw rod 23 to rotate via the output shaft; a movable plate 24 is threadedly connected to the surface of the screw rod 23; a turntable 25 is rotatably connected to the surface of the movable plate 24; A second motor 26 is fixedly connected to the surface of the turntable 25, and a drill rod 27 is fixedly connected to the output shaft of the second motor 26. The second motor 26 drives the drill rod 27 to rotate through the output shaft. A drill bit 28 is fixedly connected to the surface of the drill rod 27. A hydraulic cylinder 29 is fixedly connected to the surface of the turntable 25, and a push plate 210 is fixedly connected to the piston rod of the hydraulic cylinder 29. A connecting frame 211 is fixedly connected to the surface of the movable plate 24, and a third motor 212 is fixedly connected to the surface of the connecting frame 211. The turntable 25 is fixedly connected to the output shaft of the third motor 212, and the third motor 212 drives the turntable 25 to rotate through the output shaft.
[0022] Furthermore, a threaded hole is provided at the bottom of the movable plate 24, and the screw rod 23 is threadedly connected to the threaded hole of the movable plate 24. The movable plate 24 moves linearly on the surface of the support frame 21 through the screw rod 23. The movable plate 24 drives the movable plate 24 to move linearly during the rotation process. The movable plate 24 and the rock 12 are on the same horizontal straight line, and the movable plate 24 drives the turntable 25 to move synchronously.
[0023] Furthermore, a groove is provided on the surface of the movable plate 24 , and the turntable 25 rotates on the groove of the movable plate 24 . During the rotation process, the turntable 25 drives the drill rod 27 and the drill bit 28 to rotate synchronously, thereby changing the drilling position of the drill rod 27 and the drill bit 28 .
[0024] Furthermore, the drill bit 28 rotates on the surface of the turntable 25 through the drill rod 27. There are four groups of drill rods 27 and drill bits 28, and they are evenly distributed in a rectangular shape on the surface of the turntable 25. The drill rods 27 and drill bits 28 excavate on the rock 12, and four points are excavated on the rock 12 at the same time, thereby improving the excavation efficiency.
[0025] Furthermore, the piston rod of the hydraulic cylinder 29 passes through the turntable 25 and is fixedly connected to the push plate 210. The hydraulic cylinder 29 drives the push plate 210 to move through the piston rod. The push plate 210 can push the rock 12 to the tunnel 11, thereby completing the overall unloading of the rock 12 and improving the efficiency of excavating the communication channel.
[0026] Furthermore, two groups of hydraulic cylinders 29 are provided, and the movable plate 24 drives the hydraulic cylinders 29 to move synchronously through the turntable 25. When the drill rod 27 and the drill bit 28 move with the turntable 25 during the drilling process, when the drill rod 27 and the drill bit 28 have completed drilling the hole, the hydraulic cylinder 29 will approach the rock 12 through the turntable 25, making it convenient for the hydraulic cylinder 29 to push the rock 12 of the communication channel out through the push plate 210.
[0027] Furthermore, both ends of the connecting frame 211 are in a "Y" shape, and the third motor 212 drives the turntable 25 to rotate on the connecting frame 211. The drill rod 27 and the drill bit 28 adjust the angle through the turntable 25. The turntable 25 can rotate at a certain angle. The drill rod 27 and the drill bit 28 change the drilling position on the rock 12 by changing the angle, thereby drilling holes at multiple angles of the rock 12, making it easier for the push plate 210 to push the rock 12 out of the communication channel.
[0028] Working principle: The output shaft of the first motor 22 drives the screw rod 23 to rotate, and the screw rod 23 drives the movable plate 24 to move on the surface of the support frame 21 during the rotation. The movable plate 24 drives the drill rod 27 and the drill bit 28 to move toward the rock 12 through the turntable 25. The second motor 26 drives the drill rod 27 and the drill rod 27 to rotate through the output shaft. The drill rod 27 and the drill bit 28 drill the rock 12 by rotation. The third motor 212 drives the turntable 25 to rotate on the movable plate 24 through the rear output shaft, thereby changing the drilling position of the drill rod 27 and the drill bit 28. At this time, the connection points of the rock 12 in the communication channel become fewer, and the hydraulic cylinder 29 drives the push plate 210 through the piston rod to push the rock 12, so that the rock 12 moves toward the direction of tunnel 2 11. The push plate 210 pushes the rock 12 as a whole to tunnel 2 11, thereby improving the excavation efficiency of the communication channel.
