The A, B sides show the downward movement and upward movement of the bucket 10d by arrows, respectively. During operation, sand is also entering from the lower casing 10a and is lifted to the upper casing 10c by the chain bucket 10 d. But it is noted that this is shown in figure 3. The sand enters the lower casing 10a from the inlet port 10ca on the a side downward, and is accumulated on the bottom of the lower casing 10a after entering the lower casing 10a along the feed passage 10 g. The side chain bucket 10d is not hindered when moving downward along the feed channel 10g, and the sand is lifted to the upper casing 10c at the side chain bucket 10d after the side chain bucket 10d is turned from the side a to the side B. Therefore, during operation, the side bucket 10d moves in the same direction as the sand enters the lower casing 10a at a, so that the sand enters the lower casing 10a without being blocked.
