[0032] The specific settings and functions of the adjustment structure 4 and the auxiliary structure 5 are described in detail below.

[0033] Reference Figure 2 and Figure 3 and Figure 4As shown, in this embodiment: the adjustment structure 4 includes a rectangular tube 41, which is fixedly connected to one end of the first front probe beam 1, and a rectangular rod 42 is slidably connected to the inner wall of the rectangular tube 41, and the rectangular rod 42 is fixedly connected to the second front probe beam 2. A latch 43 is slidably penetrated through the surface of the rectangular tube 41, and a circular hole 44 is provided on the surface of the rectangular rod 42, and the size of the latch 43 matches the size of the circular hole 44. Rectangular holes 45 are provided on both sides of the rectangular tube 41, and rectangular blocks 46 are slidably connected to the inner walls of the two rectangular holes 45, and the rectangular blocks 46 are fixedly connected to the surface of the rectangular rod 42. When the rectangular rod 42 moves, it will drive the rectangular blocks 46 to slide in the rectangular holes 45, and the rectangular holes 45 have the effect of limiting the moving path of the rectangular blocks 46, thereby preventing the rectangular rod 42 from sliding out of the rectangular box. The arc surface of the latch 43 is covered with a spring 47, and the two ends of the spring 47 are fixedly connected to the latch 43 and the rectangular tube 41 respectively. The latch 43 will be inserted into the circular hole 44 with the help of the contraction force of the spring 47. The spring 47 can limit the movement of the latch 43, thereby improving the stability of the latch 43 inserted into the circular hole 44 and preventing the latch 43 from falling out of the circular hole 44. A protective pad 48 is fixedly connected to one end of the rectangular rod 42. The protective pad 48 is made of rubber. The rectangular rod 42 will drive the protective pad 48 to squeeze the inner wall of the rectangular box. The protective pad 48 can prevent the rectangular rod 42 from directly hitting the rectangular box and causing damage, thereby protecting the rectangular rod 42 and the rectangular box.

[0034] Reference Figure 5 and Figure 6 As shown, specifically, the auxiliary structure 5 includes a threaded rod 51, which is threadedly connected to the surface of the first front probe beam 1, and a circular plate 52 is rotatably connected to the end of the threaded rod 51 away from the first front probe beam 1, and a plurality of thorns 53 are fixedly connected to the side of the circular plate 52 away from the threaded rod 51. A circular groove 54 is provided on the side away from each other of the first front probe beam 1 and the second front probe beam 2, and a circular rod 55 is slidably connected to the inner wall of the circular groove 54, and the circular rod 55 is fixedly connected to the surface of the circular plate 52. When the circular plate 52 moves, it will drive the circular rod 55 to slide in the circular groove 54, and the circular groove 54 can limit the moving path of the circular rod 55, thereby limiting the moving path of the circular plate 52, thereby preventing the circular plate 52 from rotating when moving. A rotating disk 56 is fixedly connected to the surface of the threaded rod 51, and the vertical section of the rotating disk 56 is in a "cross" shape. The rotation of the rotating disk 56 will drive the threaded rod 51 to rotate, and the rotating disk 56 can facilitate the rotation of the threaded rod 51.

[0035] Working principle: when it is necessary to adjust the length of the front probe beam, first pull the latch 43, the latch 43 will move in the rectangular box and gradually come out of the round hole 44, the latch 43 will stretch the spring 47 when it moves, at this time the spring 47 is in a stretched state, when the latch 43 comes out of the round hole 44, then push the second front probe beam 2, the second front probe beam 2 will move in the direction close to the first front probe beam 1, the movement of the second front probe beam 2 will drive the rectangular rod 42 to move, the movement of the rectangular rod 42 will move in the rectangular box, the rectangular rod 42 will drive the rectangular block 46 to slide in the rectangular hole 45 when it moves, the rectangular hole 45 reaches the effect of limiting the moving path of the rectangular block 46, thereby preventing the rectangular rod 42 from sliding out of the rectangular box, when the second front probe beam 2 After moving to a suitable position, the rectangular rod 42 will drive the protective pad 48 to squeeze against the inner wall of the rectangular box. The protective pad 48 can prevent the rectangular rod 42 from directly colliding with the rectangular box and causing damage, thereby protecting the rectangular rod 42 and the rectangular box. Then the latch 43 is released, and the latch 43 is inserted into the circular hole 44 with the help of the contraction force of the spring 47. The spring 47 limits the movement position of the latch 43, thereby improving the stability of the latch 43 inserted into the circular hole 44 and preventing the latch 43 from falling out of the circular hole 44. The latch 43 limits the position of the rectangular rod 42, thereby limiting the position of the second front probe beam 2. By adjusting the depth of the rectangular rod 42 inserted into the rectangular box, the length of the front probe beam is adjusted, thereby improving the stability of the front probe beam support.

[0036] When it is necessary to install the front probe beam in the coal lane, first put the first front probe beam 1 and the second front probe beam 2 in appropriate positions, and then rotate the turntable 56 at one end of the first front probe beam 1. The rotation of the turntable 56 will drive the threaded rod 51 to rotate, and the rotation of the threaded rod 51 will move in the first front probe beam 1 with the help of the thread. The movement of the threaded rod 51 will drive the circular plate 52 to move toward the inner wall of the coal lane. When the circular plate 52 moves, it will drive the round rod 55 to slide in the circular groove 54. The circular groove 54 limits the moving path of the round rod 55, thereby limiting the moving path of the circular plate 52, thereby avoiding the circular plate 52 from rotating when moving. After moving to a suitable position, the circular plate 52 will drive the spurs 53 to insert into the inner wall of the coal lane. Repeated operations will cause the spurs 53 at one end of the second front probe beam 2 to insert into the inner wall of the coal lane, thereby fixing the first front probe beam 1 and the second front probe beam 2. The simple installation method makes it easy to move the positions of the first front probe beam 1 and the second front probe beam 2 at any time.
