PROBLEM TO BE SOLVED: To improve the efficiency of work for isolating a material to be isolated into a first material and a second material.SOLUTION: A bucket includes: a bucket body A1； an agitation part 1 rotatably disposed between side plates A10, A11 of the bucket body A1； and a filter part 2 provided in a bottom A12 of the bucket body A1 so as to face the agitation part 1. The agitation part 1 comprises: a rotating shaft 10； and an agitation member 11 provided integrally with the outer periphery of the rotating shaft 10, and agitating used livestock bedding C in the bucket body A1 following rotation of the rotating shaft 10 to isolate this material to be isolated C into compost material C1 and livestock bedding material C2. The filter part 2 comprises: a plurality of passage spaces 20 through which the compost material C1 isolated in the agitation part 1 passes； and a holding part 21 for holding the livestock bedding material C2 isolated in the agitation part 1 in the bucket body A1.【課題】被分離材料を第１材と第２材とに分ける作業の効率化。【解決手段】バケット本体Ａ１と、バケット本体Ａ１の側板Ａ１０、Ａ１１間に回転可能に配された撹拌部１と、バケット本体Ａ１の底部Ａ１２に撹拌部１と対面するように設けられたフィルタ部２とを備える。撹拌部１は、回転軸１０と、回転軸１０の外周に一体に設けられ、回転軸１０の回転に伴ってバケット本体Ａ１内の使用済み家畜敷料Ｃを撹拌して、被分離材料Ｃを堆肥原料Ｃ１と家畜敷料原料Ｃ２とに分ける撹拌部材１１とを備える。フィルタ部２は、撹拌部１で分けられた堆肥原料Ｃ１が通過する複数の通過空間２０と、複数の通過空間２０の間に確保され、撹拌部１で分けられた家畜敷料原料Ｃ２をバケット本体Ａ１内に保持する保持部２１とを備えた。【選択図】図１
