As shown in fig. 1, the wheel-track tubular belt conveyor of the present embodiment is the same as the existing tubular belt conveyor in that: the front end and the rear end of the frame 4 are respectively provided with a driving roller 8 and a tensioning roller 7; the upper part and the lower part of the frame are respectively provided with a transition frame 2 and a closing frame 3 at the front and the back (the two ends are transition frames, and the middle is a closing frame); as shown in fig. 2, the transition frame 2 includes wide channel brackets 201, curved beams 202, narrow channel brackets 203, straight beams 204, and hexagonal brackets 206; the wide groove-shaped bracket 201, the narrow groove-shaped bracket 203 and the hexagonal bracket 206 are respectively provided with a plurality of groups of carrier rollers 205 and are respectively distributed in a wide groove shape, a narrow groove shape and a hexagonal closed shape; the conveyer belt 1 is arranged between the driving roller and the tensioning roller, the two ends of the conveyer belt complete the transition from the groove shape to the tube shape (at the front end of the upper part of the conveyer belt and the rear end of the lower part of the conveyer belt) and from the tube shape to the groove shape (at the rear end of the upper part of the conveyer belt and the front end of the lower part of the conveyer belt) under the action of a plurality of carrier rollers on the transition frame, and then the conveyer belt forms a closed ring.

Unlike existing tubular belt conveyors: as shown in fig. 3 and 4, the closing frame 3 is a hexagonal cylindrical frame formed by connecting front and rear hexagonal frames 301 into a whole by four cross beams 302, and 5 groups (not limited to 5 groups) of linear guide rails 303 parallel to the cross beams are mounted on the closing frame, wherein two groups of linear guide rails are located on the bottom edge (the edge where the upper and lower closing frames are close to each other) of the closing frame, one linear guide rail is located on the top edge opposite to the bottom edge, and the other two linear guide rails are respectively located on the side edges adjacent to the top edge; the closing frame is internally provided with a group of (seven in the embodiment) moving brackets 6 which are arranged on a closed annular rope 9 and can run along a linear guide rail 303 on the closing frame and are uniformly distributed at intervals, and the moving brackets realize reversing running through a turnover track positioned on the outer side of the closing frame (comprising an upper closing frame and a lower closing frame). The conveyer belt 1 is located in the movable bracket, is wrapped by the movable bracket, and drives the movable bracket and the rope to synchronously operate with the conveyer belt through the static friction force between the conveyer belt and the movable bracket (if the static friction force between the conveyer belt and the movable bracket is not enough to drive the movable bracket and the rope to synchronously operate with the conveyer belt, a driving mechanism can be independently arranged for the rope).

As shown in fig. 5 and 6, the moving bracket 6 includes a moving base 601 and two arc arms 602 hinged to two ends of the moving base, respectively, rollers 603 capable of rolling on two linear guide rails located on the bottom side of the closed frame are respectively disposed at two ends of the moving base, and rollers 603 capable of rolling along the linear guide rails on the top side of the closed frame and the linear guide rails on the side edges adjacent to the top side are respectively disposed at the top end and the middle part of the two arc arms; the ropes 9 are two parallel to each other as shown in fig. 1, 9 and 10, and pass through the upper and lower closing frames along the bottom edges of the upper and lower closing frames; a reversing mechanism 5 (shown in figure 10) consisting of a reversing wheel 501, a reversing wheel bracket 502 and a tensioning rope wheel 503 is respectively arranged on the machine frames at the two ends of the upper and lower closing frames, and a rope is reversed by the reversing wheel 501 to form a closed ring shape and is tensioned by the tensioning rope wheel arranged on the reversing wheel bracket; two ends of a movable base 601 of the movable bracket are respectively and fixedly connected to the two ropes.

The turning track is shown in fig. 7 and 8 and comprises an outer turning track 10 and an inner turning track 11; two inner overturning tracks 11 are respectively connected with two linear guide rails at the bottom edge of the sealing frame (comprising an upper sealing frame and a lower sealing frame), and two rollers on the moving base of the moving bracket can roll along the two inner overturning tracks; two outer turning tracks 10 are respectively connected with the two linear guide rails on the side edge of the closing frame, and the rollers in the middle of the arc-shaped arm of the moving bracket can roll on the two outer turning tracks; the mutual distance between the two outer overturning tracks is gradually enlarged to be larger than the transverse width of the conveyer belt at the position, so that the two arc-shaped arms are gradually opened to stride over the conveyer belt at the position when the moving bracket moves forwards on the overturning tracks; the movable bracket realizes reversing operation through the outer overturning track and the inner overturning track, namely the movable bracket is converted from forward and backward operation in the upper sealing frame to backward and forward operation in the lower sealing frame, and from backward and forward operation in the lower sealing frame to forward and backward operation in the upper sealing frame.
