PROBLEM TO BE SOLVED: To solve a problem in which: the conventional rake for digging shellfish and the like were dangerous since a sharp portion was exposed and when digging out shellfish, collection efficiency was poor since sediment resistance was large, and it caused the time and effort to find shellfish from the dug sediment as well as oversight of shellfish.SOLUTION: In a shellfish digging equipment 1, a digging part 4 with a form supporting a flat-bar edge with both ends is attached to a handle part. Since there is no sharp portion, injury and damage to an article are hardly caused. By using this equipment and digging a surface of sediment like plowing, it is possible for an operator to detect 7 a position of shellfish 6 while being buried with a touch feel and to pick it up after visually recognizing the shellfish. By this, oversight of the shellfish is reduced it is not also required to dig up the sediment more than necessary and the time and effort to find the shellfish in the dug sediment can be reduced. Also, by widening the width of the digging part, it is possible to dig a wide range at one time as compared to the conventional rake, and thereby increasing collection efficiency.COPYRIGHT: (C)2015,JPO&INPIT【課題】従来の貝掘り用熊手等は、尖った部分が露出しており危険であった。また貝を掘り出す際には、土砂の抵抗が大きく、掘り起こした土砂の中から貝を探し出す手間が生じて見落としも発生するなど、採取効率も悪かった。【解決手段】貝掘り器具1は、フラットバー状の刃を両端で支持する形状の掘削部4が、持ち手部に取り付けられた構成とする。尖った部分がないため、怪我や物品破損の原因となりにくい。作業者はこれを用いて、土砂の表面を鋤き取るように掘ることにより、貝6が埋まったままの状態で位置を感触により感知7し、視認し取り上げることができる。これにより貝の見落としが減り、必要以上の土砂を掘り返す必要もなくなり、また掘り起こした土砂の中から貝を探し出す手間が軽減される。また掘削部の幅を広くすることによって、従来の熊手と比べて一度に広い範囲を掘ることができ、採取効率が高まる。【選択図】図4
