The frame body of the tail frame is hinged with the power frame through a universal connecting device, and the walking track is connected with the pushing track at the power frame through a track connecting plate and a pin shaft. The non-return mechanism is fixed on the rail surface of the tail frame body through bolts, and the change of the lapping stroke of the adhesive tape reversed loader and the self-moving tail can be realized by adjusting the position of the non-return mechanism on the tail frame body.

When the roadway head-on bottom cleaning operation is carried out, the heading machine (or an anchor driving machine and a continuous mining machine) is ensured to have enough bottom cleaning operation space through the retreating of the self-moving tail. The common tail needs a heading machine (or an anchor driving machine or a continuous mining machine) to retreat as a support, and the tail is manually pushed backwards by adopting a single oil cylinder, so that the labor intensity of workers is high, and casualties and equipment damage are easy to occur.
What has been described above are merely some embodiments of the present invention.
