PURPOSE:To improve working efficiency, by a method wherein a body bucket and an openable bucket are openably secured, a rotary shaft is protruded from a rotary drive source attached to the body bucket, and the rotation force of the rotary shaft is transferred to the driven part of the openable bucket. CONSTITUTION:With a motor 5 secured to a body bucket 2 driven, a gear shaft 4, coaxially protruded from a motor 5, is geared with an internal gear 6 formed in an openable bucket 2', and the buckets 2 and 2' are rotated around a gear shaft 4 for opening and closing. This, even in case relatively large rock is included in soil, enables to perform an easy scooping-up work. |
