本発明は、ショベル機械用のバケットに付設されるツース盤及び該ツース盤を備えるショベル機械用のバケットに関するものであり、詳しくは、製作時間を多く必要とせず、製作コストの低廉化を図ることができ、メンテナンスも簡略であり、地盤等の均一な均し作業が可能であり、更に耐衝撃性にも優れたショベル機械用のバケットに付設されるツース盤及び該ツース盤を備えるショベル機械用のバケットに関するものである。   The present invention relates to a tooth machine attached to a bucket for an excavator machine and a bucket for an excavator machine provided with the tooth machine. Specifically, the invention does not require much production time, and the production cost is reduced. It is easy to maintain, uniform leveling work of the ground etc. is possible, and the excavator machine equipped with the tooth machine and the excavator machine equipped with the tooth machine with excellent impact resistance It is about the bucket of.

従来のショベル機械用のバケットに付設されるツース盤としては、例えば当該ショベル機械専用で他のショベル機械に適合しない鉄板溶接仕様のものが知られている。   As a tooth machine attached to a bucket for a conventional shovel machine, for example, an iron plate welding type dedicated to the shovel machine and not compatible with other shovel machines is known.

このような鉄板溶接仕様のツース盤の場合、耐衝撃性は高いという機能を有するものの、その組み立てに際して熟練工による溶接作業が必須であり、製作時間が多く必要で製作コストが高くなり、更にメンテナンスも煩雑となるという問題を有している。   In the case of such an iron plate welding specification tooth machine, although it has a function of high impact resistance, welding work by a skilled worker is indispensable for its assembly, which requires a lot of production time, increases the production cost, and also performs maintenance. It has the problem of becoming complicated.

特許文献１には、各基端側にバケット側から突出させたアダプターに装着可能な嵌入用凹陥部を設け、各突出端側に掘削用の土砂等に食い込ませる刃部を露出状態に設けた右ツース部材、中央ツース部材、及び左ツース部材の並設構造でショベル機械用のバケットに付設されるツース盤であって、前記ツース盤の突出端側から見て、前記右ツース部材の中央ツース部材側の左側面部に、上面遮蔽部材を用いた前記中央ツース部材用の間隔調整用凹陥部を設け、前記左ツース部材の中央ツース部材側の右側面部に、中央ツース部材の左側面部内に嵌入する間隔調整用突出部を設け、前記中央ツース部材は、右側面部に間隔調整用突出部を具備し、左側面部に上面遮蔽部材を用いた間隔調整用凹陥部を具備し、前記各刃部を並設方向で一直線状態を維持しつつ前記各ツース部材間の並設方向の間隔調整を各々可能とするとともに、前記各上面遮蔽部材の基端側を前記バケットのバケットエッジ部の略真上に至る範囲に突出させ、前記各間隔調整用突出部の基端側を前記バケットのバケットエッジ部の近傍に至る範囲に突出させ構成からなるショベル機械用のバケットに付設されるツース盤が提案されている。   In Patent Document 1, a recessed portion for insertion that can be attached to an adapter that protrudes from the bucket side is provided on each base end side, and a blade portion that is bitten into excavated earth and sand is provided on each protruding end side in an exposed state. A tooth machine attached to a bucket for an excavator machine in a side-by-side structure of a right tooth member, a central tooth member, and a left tooth member, the central tooth of the right tooth member as viewed from the protruding end side of the tooth machine On the left side of the member side, a recess for adjusting the distance for the central tooth member using the upper surface shielding member is provided, and the right side of the left tooth member on the side of the central tooth member is fitted into the left side of the central tooth member. The central tooth member has a spacing adjustment projection on the right side surface, a spacing adjustment recess using an upper surface shielding member on the left side surface, and the blades Straight line in parallel direction While maintaining each of the spacing in the parallel arrangement direction between the respective tooth members while maintaining, the base end side of each of the upper surface shielding member is protruded in a range that reaches almost directly above the bucket edge portion of the bucket, There has been proposed a tooth board attached to a bucket for an excavator machine having a configuration in which the base end side of each interval adjusting protrusion protrudes in a range reaching the vicinity of the bucket edge portion of the bucket.

しかしながら、従来における前記特許文献１のツース盤の場合、以下のような問題を包含している。   However, the conventional tooth board of Patent Document 1 includes the following problems.

すなわち、特許文献１のツース盤の場合、各ツース部材間の並設方向の間隔調整が可能であることから多くの寸法の異なるバケットに対応できること、鉄板溶接仕様のものに比べて低コストで済み、メンテナンスも簡易であること等が大きな利点であるが、間隔調整することでその間隔調整により刃先先端（正面下側の接地面）に凹凸状の溝が発生することから、均一な均し作業においては使用が制限されることがあった。   That is, in the case of the tooth board of Patent Document 1, the distance between the tooth members can be adjusted in the parallel direction, so that it can be used for buckets having many different dimensions, and can be manufactured at a lower cost compared to the steel plate welding specification. Easy maintenance, etc. is a great advantage, but by adjusting the interval, uneven grooves are generated at the tip of the blade edge (the ground contact surface on the lower side of the front) by adjusting the interval, so uniform leveling work In some cases, use was limited.

また、特許文献１のツース盤の場合、各ツース部材間の間隔調整範囲が限定的であり、限度を超えて対応するためには新たに製作する必要があり、金型製作コスト並びに製作期間を数か月要するという問題もあった。   In addition, in the case of the tooth board of Patent Document 1, the range of adjustment between the tooth members is limited, and it is necessary to newly manufacture in order to cope with exceeding the limit. There was also a problem that it took several months.

このような初期投資を控えることから、現在でも多数の従来技術で対応ができないバケットサイズが数多く存在している。   In order to refrain from such initial investment, there are still many bucket sizes that cannot be handled by many conventional technologies.

更に、特許文献１のツース盤の場合、間隔調整部の構成から上下部材の重なりという構造上の特徴があり、その問題を解決するには製品重量増加、又は大幅な形状変更が必要なことからも、耐衝撃性の向上という問題解決は困難であった。   Furthermore, in the case of the tooth board of Patent Document 1, there is a structural feature that the upper and lower members overlap due to the configuration of the interval adjustment unit, and in order to solve the problem, an increase in product weight or a significant shape change is required. However, it has been difficult to solve the problem of improving impact resistance.

なお、上述した実施例において、前記中央ホルダーツース１１、左右兼用ホルダーツース２１、スペースツース３１、弾性緩衝体４１の各個数は、バケット５１及び既存アダプター６１の形態に応じて任意に設定できる。   In the above-described embodiment, the number of the center holder tooth 11, the left / right holder tooth 21, the space tooth 31, and the elastic shock absorber 41 can be arbitrarily set according to the form of the bucket 51 and the existing adapter 61.

また、前記スペースツース３１、前記衝撃緩衝体４１の幅寸法は、既存のアダプター６１の間隔に応じて任意の幅とすることができるので、スペースツース３１、前記衝撃緩衝体４１のみを変更すれば、異なる間隔のアダプター６１を備えるバケット５１に対しても容易に対応することができる。   Moreover, since the width dimension of the space tooth 31 and the shock absorber 41 can be set to an arbitrary width according to the interval between the existing adapters 61, if only the space tooth 31 and the shock absorber 41 are changed. Further, it is possible to easily cope with the bucket 51 including the adapters 61 having different intervals.

更に、前記バケット５１及び既存のアダプター６１の形態（大きさ・既存アダプターの間隔）に応じて、前記中央ホルダーツース１１、左右兼用ホルダーツース２１、スペースツース３１、衝撃緩衝体４１の形状・サイズは任意に設定可能である。   Furthermore, the shape and size of the central holder tooth 11, the left / right combined holder tooth 21, the space tooth 31, and the shock absorber 41 according to the form (size / interval between existing adapters) of the bucket 51 and the existing adapter 61 are as follows. It can be set arbitrarily.
