ト１０、１０よりも大きくなっている。Next, the construction of a bucket elevator using the bucket 5 of the present invention constructed as described above will be explained. In FIG. 4, a lower pulley 8 is arranged in a lower portion of a casing 7 having a sand inlet 6 and a sand outlet (not shown), and an upper pulley (not shown) is arranged in an upper portion. ing. A belt 9 is stretched over the lower pulley 8 and an upper pulley (not shown). The plastic buckets 10 and 10 and the bucket 5 of the present invention are placed on the belt 9 in the former four. The latter one is attached to the. The outer dimensions of the bucket 5 of the present invention in the width direction a and the front-rear direction b are larger than those of the plastic buckets 10 and 10.
