IPC: B65G67/60
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a bucket wheel-type unloader for alleviating a collision of a bucket with the bottom of a ship. SOLUTION: A ring 44 whose outer periphery is covered with an elastic member 6 is provided on the outer peripheral part of a bucket wheel 28 formed by annularly arranging a plurality of buckets 36. When the bucket wheel 28 collides with the bottom 30A after the bottom 30A is oscillated, the lower end of the ring 44 provided on the outer peripheral part of the bucket wheel 28 always collides with the bottom 30A. When the lower end of the ring 44 collides with the bottom 30A, a vertical component of the speed by the rotation of the ring 44 is eliminated on the lower end of the ring 44, only a horizontal component remains, and therefore, collision force has only a vertical component of the speed by oscillation of the bottom 30A. Therefore, a collision of the bottom 30A with the bucket wheel 28 is alleviated, and damage of the bottom 30A and the bucket 36 is prevented.
