Description

本考案は、土木工事等に使用する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し、詳しくは、複数のツース部材を間隔調整可能に並設して異なるサイズのバケットに対応可能であるとともに、当該間隔調整を行った場合においても作業効率の低下を招くことのない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 used for civil engineering work and the like, and more specifically, a bucket for an excavator machine provided with the tooth machine. A tooth machine attached to a bucket for an excavator machine that is compatible with buckets of different sizes and does not cause a reduction in work efficiency even when the interval is adjusted, and an excavator machine equipped with the tooth machine. It is about the bucket.

従来、パワーショベルやショベルローダなどのショベル機械のバケットには、その底部先端位置にアダプター部材の基部を溶接その他の方法により止着し、このアダプター部材―に整地作業用のツース盤の係合凹部を被嵌し、ロックピン部材などの固定手段によりアダプター部材とツース盤とを一体的に固定し、これにより、掘削した土砂や砂利や岩片などの整地や運搬車などへの積み込みを行っていた。 Conventionally, in the bucket of an excavator machine such as a power shovel or excavator loader, the base of the adapter member is fixed to the tip of the bottom by welding or other methods, and the engaging recess of the tooth machine for leveling work is attached to the adapter member. The adapter member and the tooth board were fixed integrally by a fixing means such as a lock pin member, and by this, the excavated earth and sand, gravel, rocks, etc. were loaded into leveling or a transport vehicle, etc. .

この種のツース盤においては、異なるサイズのバケットに対応するために複数のツース部材を間隔調整可能に並設して、その全幅が広狭に変更可能であることが好ましい。 In this type of tooth machine, it is preferable that a plurality of tooth members are arranged side by side so as to be adjustable in order to accommodate buckets of different sizes, and the entire width thereof can be changed widely.

特許文献１には、本考案の関連技術として、ショベル系掘削機のバケットの掘削縁部にアダプターを介して着脱自在に突設されるツース部材であって、上記ツース部材は上記アダプターが嵌入可能な嵌入凹部及び掘削作用をなす歯板部からなり、該嵌入凹部の裏側の左右方向の一方部に間隙設定部を突設し、該間隙設定部の一方側部に該歯板部を構成する差込板部を形成し、該間隙設定部の他方側部に該歯板部を構成する裏側板部を形成し、該嵌入凹部の他方側部に該裏側板部との間に該差込板部を差込可能な差込間隙を存して押さえ板部を突設する構成としたショベル系掘削機用ツース部材が開示されている。 In Patent Document 1, as a related technique of the present invention, there is a tooth member that is detachably protruded from an excavation edge of a bucket of an excavator excavator via an adapter, and the adapter can be inserted into the tooth member. A gap setting portion projecting from one side in the left-right direction on the back side of the insertion recess, and forming the tooth plate portion on one side of the gap setting portion An insertion plate portion is formed, a back side plate portion constituting the tooth plate portion is formed on the other side portion of the gap setting portion, and the insertion portion is provided between the back side plate portion and the other side portion of the insertion recess. There has been disclosed a tooth member for an excavator excavator having a structure in which a pressing plate portion is provided so as to protrude with an insertion gap into which the plate portion can be inserted.

しかし、特許文献１のショベル系掘削機用ツース部材においては、嵌入凹部の裏側における左右方向の一方部に間隙設定部を突設し、該間隙設定部の一方側部に該歯板部を構成する差込板部を形成し、該間隙設定部の他方側部に該歯板部を構成する裏側板部を形成し、該嵌入凹部の他方側部に該裏側板部との間に該差込板部を差込可能な差込間隙を存して押さえ板部を突設し、このツース部材を複数個並設して前記間隙設定部と差込板部との嵌め合い構造で複数個並設してツース盤とするものである。 However, in the tooth member for the excavator excavator of Patent Document 1, a gap setting portion is protruded on one side in the left-right direction on the back side of the fitting recess, and the tooth plate portion is configured on one side of the gap setting portion. An insertion plate portion is formed, a back side plate portion constituting the tooth plate portion is formed on the other side portion of the gap setting portion, and the difference is provided between the back side plate portion and the other side portion of the insertion recess. A holding plate portion is provided in the presence of an insertion gap into which the insertion plate portion can be inserted, and a plurality of tooth members are arranged side by side to provide a plurality of fitting structures between the gap setting portion and the insertion plate portion. A tooth board is formed side by side.

このため、このような構成のツース盤においては、間隙設定部や差込板部の上面は露出し何等の遮蔽部材は存在しないため、このツース盤を使用して土砂等の掘削作業を行う際に、前記間隙設定部と差込板部との嵌め合い位置を調整して隣り合うツース部材の間の間隔を調整し全体の並設方向の幅を広げたような場合、差込板部の嵌め込み先端側と間隙設定部の最奥部との間に隙間が生じ、この隙間からの土砂の漏れ落ちる量が増え、土砂等の掘削作業効率を低下させたり、間隙設定部の最奥部に付着した土砂の除去作業が必要になるという問題を包含し、かつ、ショベル系掘削機用のバケットエッジ（リップ部）が掘削作業時に露出することから、該バケットエッジ（リップ部）の摩耗が生ずるという問題をも包含している。 For this reason, in the tooth machine having such a configuration, the upper surfaces of the gap setting part and the insertion plate part are exposed and there is no shielding member. Therefore, when excavating work such as earth and sand using this tooth machine, In addition, when the fitting position between the gap setting portion and the insertion plate portion is adjusted to adjust the interval between adjacent tooth members and widen the entire parallel arrangement direction, A gap is created between the fitting tip side and the innermost part of the gap setting part, and the amount of earth and sand leaking from this gap increases, reducing the efficiency of excavation work such as earth and sand, or at the innermost part of the gap setting part Including the problem that it is necessary to remove the adhering earth and sand, and because the bucket edge (lip part) for the excavator excavator is exposed during excavation work, wear of the bucket edge (lip part) occurs. The problem is also included.
