After being redirected twice by the belt pressing roller 302 on the belt guide part 3, it penetrates into the reserved belt groove of the front support part 2, and then enters the reserved belt groove of the main frame 1, bypasses the redirecting roller 608 and becomes the upper belt. The upper belt is redirected by the trolley belt pressing roller 611 and passes under the revolving bridge 605. Then the upper belt passes through the middle of the coal guide plate 602 and the grooved roller 306 of the belt guide part 3 and enters the upper roller group of the belt conveyor.

[0047] A push cylinder 7 is installed between the main frame 1 and the trolley frame 601 of the traveling trolley 6. The push cylinder 7 is used to push the traveling trolley 6 to move. The push cylinder 7 can also use the chute bridge transfer machine and the traveling trolley 6 as fulcrums to pull the tail of the self-moving machine forward. The slewing bridge 605 of the traveling trolley 6 is connected to the pin shaft of the head of the bridge transfer machine as a fulcrum. When the push cylinder 7 is retracted, the traveling trolley 6 is fixed relative to the bridge transfer machine, and the push cylinder 7 pulls the main frame 1 to move.
