[0025] Specifically, the first driving mechanism 3 includes a jack 301 and a third hinge 302, the left and right ends of the jack 301 are connected with the third hinge 302, and the left and right third hinges 302 are respectively connected to the left inner wall of the tail beam body 1 and the left inner wall of the rectangular box 8.

[0026] In this embodiment, the left and right third hinges 302 and the jack 301 connect the tail beam body 1 with the plugboard body 2 , and the output shaft of the jack 301 can drive the plugboard body 2 to move up and down in the tail beam body 1 .

[0027] Specifically, the second driving mechanism 9 and the third driving mechanism 13 have the same structure as the first driving mechanism 3 .

[0028] In this embodiment, the second driving mechanism 9 enables the movable plate 7 to move up and down reciprocally, and the third driving mechanism 13 adjusts the inclination angle of the main body 1 of the tail beam.

[0029] Specifically, the guiding mechanism 4 includes a guide rail 401 and a slide rail 402. Guide rails 401 are fixedly installed on the inner walls of the lower sides of the main body 1 of the tail beam near the left side, and slide rails 402 are fixedly installed on the inner walls of the upper sides of the corresponding plug board main bodies 2. The slide rails 402 are movably buckled on the guide rails 401.

[0030] In this embodiment, the slide rail 402 moves left and right on the guide rail 401, so as to guide the moving process of the plug board main body 2.

[0031] Specifically, the track of the slide rail 402 is composed of two main rib plates and a plurality of rib plates.

[0032] In this embodiment, the slide rail 402 has high structural strength and is not easily damaged.

[0033] Specifically, a rectangular opening 14 is formed in the corresponding plug board main body 2 of the second driving mechanism 9.

[0034] In this embodiment, the rectangular opening 14 meets the requirement for the up and down movement of the second driving mechanism 9.

[0035] Specifically, pin holes 15 are formed in the lower surfaces of the main body 1 of the tail beam and the plug board main body 2 near the left side, and a pin shaft 16 is inserted into the pin holes 15.

When the main inserting plate 2 is extended, through the cooperation of the third driving mechanism 13 and the second hinge member 11, the inclination angle of the main tail beam 1 can be adjusted, that is, the inclination angle of the main inserting plate 2 can be adjusted, and then coal caving starts. During the coal caving process, when the upper surface of the main inserting plate 2 docks with coal lumps, the second driving mechanism 9 drives the movable plate 7 to reciprocate up and down along the first hinge member 6. The up and down movement angle of the movable plate 7 is from zero to ten degrees, and then the vibration motor 10 drives the movable plate 7 to vibrate, effectively avoiding the accumulation of coal lumps on the main inserting plate 2 and making the coal caving smoother.

[0038] In summary, for the new tail beam body track device of the top coal caving support, the structure of the main inserting plate 2 is simple, the guiding mechanism 4 is tightly connected, making the movement of the main inserting plate 2 more stable, with complete support and not prone to leaking gangue. At the same time, the up and down movement and vibration functions of some structures of the main inserting plate 2 are added, effectively avoiding the accumulation of coal lumps on the main inserting plate 2 and making the coal caving smoother.
