[0027] Next, with reference to the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0029] Referring to Figure 1 、 Figure 2 and Figure 3 , a self - moving tail for a fully - mechanized heading face that is easy to adjust in the present invention includes a tail frame 1. Fixedly connected to both sides of the tail frame 1 are fixing plates 2. The tops of the fixing plates 2 are penetrated and provided with sliding grooves 3 to facilitate the movement in cooperation with the sliding bars 23. On the tops of both fixing plates 2 are provided mounting boxes 4. The outside of the mounting box 4 is not closed. Fixedly connected inside the mounting box 4 is a motor 5. The motor 5 drives the lead screw 6 to rotate. The output end of the motor 5 is fixedly connected to the lead screw 6. Through the lead screw 6, two moving seats 7 can be driven to move. Threadedly connected to the outside of the lead screw 6 are two moving seats 7. Fixedly connected to the outside of both moving seats 7 are connecting seats 8, which play a connecting role. On the top of the left - hand connecting seat 8 is provided a connecting component. Rotatably connected to both sides of the tail frame 1 are first cylinders 11. Through the first cylinders 11, the displacement of the tail frame 1 can be driven. The output ends of the first cylinders 11 are connected to the connecting component. Fixedly connected to the bottoms of the connecting seats 8 and the four corners of the bottom of the tail frame 1 are buffer plates 13. At the bottom of the buffer plates 13 are provided buffer seats 12 to facilitate shock absorption. Two sliding grooves 14 are opened at the top of the buffer seats 12 to facilitate the sliding of the sliders 15. Slidingly connected in the sliding grooves 14 are two sliders 15. Through the sliders 15, the damping springs 18 can be squeezed. Rotatably connected to the opposite sides of both sliders 15 are movable rods 16. Rotatably connected to the opposite sides of both movable rods 16 are connecting bars 17. Fixedly connected to the bottom of the outer buffer seat 12 are two second cylinders 19. Through the second cylinders 19, the lifting of the first connecting plate 20 can be controlled. The output ends of the second cylinders 19 are fixedly connected to the first connecting plate 20. Fixedly connected to the bottom of the inner buffer seat 12 are two third cylinders 21. The output ends of the third cylinders 21 are fixedly connected to the second connecting plate 22. Through the third cylinders 21, the lifting of the second connecting plate 22 can be controlled.

[0030] Referring to Figure 1 , the connecting component includes a connecting block 9. The bottom of the connecting block 9 is fixedly connected to the connecting seat 8. Rotatably connected to the inside of the connecting block 9 is a rotating frame 10. The other end of the rotating frame 10 is rotatably connected to the output end of the first cylinder 11. Through the cooperation of the connecting component and the first cylinder 11, it is convenient to drive the sliding bar 23 to slide in the sliding groove 3, so as to move the tail frame 1.

[0031] Referring to Figure 1 、 Figure 2 and Figure 3 ,both moving seats 7 are arranged inside the mounting box 4, and the moving seats 7 are slidably connected to the inner wall of the mounting box 4. The inside of the mounting box 4 plays a role in limiting the moving seats 7. The top of the connecting strip 17 is fixedly connected to the buffer plate 13. Both bottoms of the two mounting boxes 4 are fixedly connected with sliding strips 23, and the outside of the sliding strips 23 is slidably connected to the inner wall of the sliding groove 3, which facilitates the displacement adjustment of the tail frame 1. The second connecting plate 22 is arranged inside the first connecting plate 20. The alternate movement of the first connecting plate 20 and the second connecting plate 22 can drive the overall movement of the tail frame 1. On the opposite sides of the two sliders 15, damping springs 18 are arranged, and the damping springs 18 are arranged inside the sliding grooves 14.

[0032] Working principle: During operation, first control the second connecting plate 22 to press tightly against the ground, control the first connecting plate 20 to be suspended by the contraction of the second cylinder 19, then start the motor 5 to drive the screw rod 6 to rotate, drive the moving seat 7 and the lower first connecting plate 20 to move through the screw rod 6. After the movement of the first connecting plate 20 is completed, control the first connecting plate 20 to press tightly against the ground through the second cylinder 19, then control the second connecting plate 22 to be suspended through the third cylinder 21, start the first cylinder 11 to extend and retract, drive the connecting block 9 and the moving seat 7 to move through the rotating frame 10. At this time, the motor 5 is in the off state, so the mounting box 4 and the moving seat 7 are fixedly connected. When the moving seat 7 moves, it can drive the mounting box 4 to slide in the sliding groove 3 inside the fixing plate 2, thereby driving the movement of the tail frame 1. After the movement of the tail frame 1, the first connecting plate 20 and the second connecting plate 22 are made to correspond to each other, realizing a complete movement adjustment process. While the first connecting plate 20 and the second connecting plate 22 move alternately, when the buffer seat 12 is under pressure, the two movable rods 16 squeeze the sliders 15 towards both sides, and the sliders 15 squeeze the damping springs 18. The damping springs 18 contract to generate elastic force, and due to the elastic force of the damping springs 18 rebounding, the received vibration force can be offset and weakened, thereby being able to damp the tail frame 1.
