BOTTOM SAMPLER
PROBLEM TO BE SOLVED: To provide a bottom sampler that is lightweight and easy to handle, and allows stable collection in investigation for collecting bottom sediment of a sea-bottom, a river bed, and a lake bottom.SOLUTION: A bottom sampler includes: a bucket opening/closing frame 3 that allows an opening/closing operation of a dividable bucket 2; and a balance hook 4 that has a hook 41 on one end side on which a slide long hole 42 is formed, and has a balance weight 43 on the other end side. The balance hook 4 is formed so as to keep an upward state of the hook 41 when a load is applied to the hook 41, and to keep a downward state of the hook 41 when the load is not applied to the hook 41. When the hook 41 is in the upward state, an opened state of the bucket 2 is kept by opening of the bucket opening/closing frame 3. When the hook 41 is in the downward state, a closed state of the bucket 2 is kept by closing of the bucket opening/closing frame 3.
【課題】軽量で取り扱いが容易であって、海底や河床、湖底の底質採取調査の際に安定した採取が可能な採泥器を提供する。【解決手段】分割可能なバケット２の開閉動作を可能にするバケット開閉フレーム３と、一端側にフック４１を有すると共にスライド長孔４２が形成され、他端側にバランスウェイト４３を有するバランスフック４とを備え、該バランスフック４は、フック４１に荷重がかかる際にはフック４１が上向き状態を保ち、フック４１に荷重がかからない際にはフック４１が下向きとなるように形成されている。フック４１が上向き状態の際には、バケット開閉フレーム３が開くことで、バケット２が開いた状態を保ち、フック４１が下向き状態の際には、バケット開閉フレーム３が閉じることで、バケット２が閉じた状態を保つ。【選択図】図１
