Title:
BUCKET AND POWER SHOVEL EQUIPPED WITH IT
Document Type and Number:
Japanese Patent JP3935916
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a bucket which enables a rootstock to be recovered by separating the rootstock and sediment, contained in soil from each other, and a power shovel which is equipped with the bucket.
SOLUTION: An opening 12 of a porous sieve bucket 10 is directed downward; a this-side edge 11 of a bottom plate 10A faces the sediment; and the soil which contains the rootstock is scooped into it. Since the porous sieve bucket 10 scoops the soil along a curved surface of the bottom plate 10A, the soil can be easily scooped into the porous sieve bucket 10. The opening 12 of the porous sieve bucket 10 is stopped obliquely upward. Additionally, the sediment is sifted from the inside of the porous sieve bucket 10 through a large-diameter hole 16A, a small-diameter hole 16B and a middle-size diameter hole 17. Thus, the root stock which is contained in the soil remains in the porous sieve bucket 10. Consequently, the rootstock and the sediment which are contained in the soil are separated from each other, so that the rootstock can be recovered.
