The using method of the invention has the following working principle:

when carrying out material transport, cup joint belt 12 on the surface of drive roller 5, according to the transport condition, adjust the position and the position of belt 12, after the adjustment finishes, start motor 4, make motor 4 drive axis 2 and drive roller 5 respectively and rotate, when drive roller 5 rotated, belt 12 continuity transmission made the material constantly carried away.

When the material drops to the inside surface of belt 12 carelessly, the material continues to move along with the internal surface of belt 12, stops to form remaining and piles up to the position of drive roller 5, and at this moment, drive roller 5 inboard clear away blade 6 scrapes remaining material, avoids the material to pile up in the inboard of drive roller 5.

When the belt 12 generates a left-right deviation phenomenon, the belt 12 gives an outward thrust to the movable plate 8, the movable plate 8 extrudes the protective layer 7 outwards, air in an inner cavity between the protective layer 7 and the movable plate 8 is discharged outwards through the exhaust port 9, air flow discharged from the exhaust port 9 blows the surface of the cleaning blade 6, materials scraped off by the cleaning blade are blown off, the blown materials pass through the top opening of the material receiving barrel 1 and enter the inner cavity of the material receiving barrel 1, the motor 4 drives the middle shaft 2 and the material conveying spiral blades 3 to rotate, and the materials are conveyed outwards continuously until the inner cavity of the recovery box 11 and are collected and recovered through the recovery box 11.

Meanwhile, when the belt 12 presses the movable plate 8, the spring 10 is compressed, and a repulsive force is given to the movable plate 8 by the repulsive force of the spring 10, so that the movable plate 8 reversely presses the belt 12, the belt 12 reversely moves, and the offset motion of the belt 12 is corrected, so that the belt 12 can keep a normal track and rotate.

When the material transportation is not needed, the motor 4 is turned off.
