PURPOSE:To surely perform smooth discharge of a material with simple construction, by providing two guide rollers in left and right side bottom parts of a bucket and forming the bucket such that the bucket tilted by one guide means is overturned by the other guide means to discharge the material. CONSTITUTION:When guides 24, 25 of a bucket are in an ascending position, the guide 24 scoops up a guide roller 15 by an ascending slope 26 to tilt the bucket 3 clockwise in a relatively gentle state of tilting motion. A guide roller 14, after passing through immediately below a roller shaft 2 by tilging motion, runs on the guide 25 from its ascending slope 27 to its top surface 28 to further tilt the bucket 3. The top surface 28 at its ascending is placed in the upper center of a hopper 4, and the bucket 3 is tilted to an overturned attitude to discharge a transfer material S to the hopper 4. Then if the roller 14 is contacted to a slope 29 to descend, a tilt angle of the bucket 3 is decreased, and the roller 15 is contacted to a slope 30 of the guide 24 to descned then the bucket 3 is reset to a horizontal attitude. |
