PURPOSE:To fully tilt and move a bucket into a head part sprocket and then return the bucket to a horizontal attitude, by successively engaging two guide rollers to a guide rail. CONSTITUTION:If a bucket 3 is moved advancing to the upper of a hopper 5 in a horizontal movement section, a guide roller 15 rides on a slope 26 of a guide rail 21 to tilt the bucket 3 with a roller shaft 2 as the center. A guide roller 14 runs on a slope 27 of a trapezoidal part 23 after passing immediately below the shaft 2 by said tilting of the bucket, and the bucket 3 is further tilted, when the roller 14 runs on a top surface of the part 23, the bucket 3 is tilted forward at least 90 deg. to discharge a transfer material to the hopper 5. The bucket 3 completed with discharge holds a prescribed tilt angle to advance by contacting the roller 14 to a flat part 24 and is lowered and reset to a horizontal attitude by contacting the roller 15 to a steep slope 30 of a guide rail 22. |
