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、間隔調整を行っても作業効率の低下を招くことが無く、更にバケットのバケットエッジ部の摩耗、損傷等も低減可能な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. It is attached to a bucket for a shovel machine that can handle buckets of different sizes, does not cause a decrease in work efficiency even if the interval is adjusted, and can reduce wear and damage of the bucket edge of the bucket. The present invention relates to a tooth machine and a bucket for an excavator machine including the tooth machine.

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 a shovel machine such as a power shovel or a shovel loader, the base of the adapter member is fixed to the bottom end position 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 integrally fixed by a fixing means such as a lock pin member and the like, so that the excavated earth and sand, gravel, rock fragments, etc. were loaded on a leveling or transport vehicle.

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、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 able to adjust the distance in order to correspond to buckets of different sizes, and the entire width thereof can be varied.

この種のツース盤におけるツース部材、アダプター連結構造の従来の例について図１０、図１１を参照して説明する。 A conventional example of a tooth member and adapter connection structure in this type of tooth board will be described with reference to FIGS.

図１０は図示しないがバケットの端部側からバケットエッジ（リップ部）１１１を突出させ、このバケットエッジ（リップ部）１１１に取り付けたアダプター１１２に対してツース部材１０１を装着し、一体化した状態を示すものである。 Although not shown in FIG. 10, the bucket edge (lip portion) 111 protrudes from the end portion side of the bucket, and the tooth member 101 is attached to the adapter 112 attached to the bucket edge (lip portion) 111 so as to be integrated. Is shown.

図１１は、図示しないがバケットのバケットエッジ部１２１と同方向に並設するツース部材１０１、１０１同士をスライド嵌合構造で組み合わせ、このようなツース部材１０１を４連又は５連等に並設してツース盤を構成する例を示すものである。 In FIG. 11, although not shown, the tooth members 101 arranged in parallel in the same direction as the bucket edge portion 121 of the bucket are combined with each other in a slide fitting structure, and such tooth members 101 are arranged side by side in 4 or 5 stations. Thus, an example of configuring a tooth board is shown.

前記ツース部材１０１は、その中央部の基端側に連結ピン１０３用のピン穴１０４を具備し、バケット側から突出させたアダプター１１２が装着可能な嵌入用凹陥部１０２を設けているとともに、突出端側に掘削用の土砂等に食い込ませる歯部１０５を露出状態に設けている。 The tooth member 101 has a pin hole 104 for the connecting pin 103 on the base end side of the central portion thereof, and is provided with a fitting recessed portion 102 into which an adapter 112 protruded from the bucket side can be attached. A tooth portion 105 that is digged into excavated earth and sand is provided on the end side in an exposed state.

また、ツース部材１０１は、図１１において、嵌入用凹陥部１０２の右側面部に土砂等が基端側から突出端側に流落可能な形状とした間隔調整用突出部１０６を具備し、左側面部に上面を土砂等が基端側から突出端側に流落可能な形状とした上面遮蔽部材１０７を用いた間隔調整用凹陥部１０８を具備している。 In addition, the tooth member 101 includes a gap adjusting protrusion 106 on the right side surface of the recess 102 for insertion shown in FIG. 11 so that earth and sand can flow from the base end side to the protrusion end side. A gap adjusting recess 108 is provided using an upper surface shielding member 107 whose upper surface is shaped such that earth and sand can flow from the base end side to the protruding end side.

そして、隣り合うツース部材１０１、１０１のうちの一方におけるツース部材１０１の間隔調整用突出部１０６を、他方のツース部材１０１の間隔調整用凹陥部１０８に嵌合させ、各ツース部材１０１、１０１の嵌入用凹陥部１０２、１０２の中心位置間の寸法を隣り合うアダプター１１２、１１２間の寸法に合致するように間隔調整しつつ各アダプター１１２に対して各ツース部材１０１の嵌入用凹陥部１０２を装着し、連結ピン１０３をピン穴１０４に打ち込んで、これらを各アダプター１１２に一体的に取り付けるものである。 Then, the spacing adjustment protrusion 106 of the tooth member 101 in one of the adjacent tooth members 101, 101 is fitted into the spacing adjustment recess 108 of the other tooth member 101, and The insertion recesses 102 of the respective tooth members 101 are attached to the respective adapters 112 while adjusting the distance between the center positions of the insertion recesses 102 and 102 so as to match the dimension between the adjacent adapters 112 and 112. Then, the connecting pin 103 is driven into the pin hole 104, and these are integrally attached to each adapter 112.

この場合に、上面遮蔽部材１０７においてはその基端側がバケットエッジ部１２１の略真上に至る位置まで延長されているが、間隔調整用突出部１０６の基端側の位置はツース盤自体の基端側の位置と合致する位置である。 In this case, although the base end side of the upper surface shielding member 107 is extended to a position almost directly above the bucket edge portion 121, the base end side position of the spacing adjustment projection 106 is the base of the tooth board itself. It is a position that matches the position on the end side.

この結果、図１１に示すように、一方におけるツース部材１０１の間隔調整用突出部１０６を、他方のツース部材１０１の間隔調整用凹陥部１０８に嵌合させて行う両ツース部材１０１、１０１の間隔調整を行った際、特に両ツース部材１０１、１０１の間隔を大とした際に、間隔調整用突出部１０６の基端側と、バケットエッジ部１２１との間に大きな隙間Ｓ（図１１において黒塗り楕円形で示す）が生じてしまい、掘削作業時において隙間Ｓからの土砂漏れによる作業効率低下を招いたり、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）バケットエッジ部１２１の摩耗による耐久性が損なわれるという問題を包含していた。 As a result, as shown in FIG. 11, the spacing between the two tooth members 101, 101 is performed by fitting the spacing adjustment protrusion 106 of one tooth member 101 into the spacing adjustment recess 108 of the other tooth member 101. When adjustment is performed, particularly when the distance between the tooth members 101 and 101 is increased, a large gap S (black in FIG. 11) is formed between the proximal end side of the interval adjustment protrusion 106 and the bucket edge 121. From the fact that the work efficiency is reduced due to earth and sand leakage from the gap S during excavation work, or the bucket edge (lip part) for the excavator excavator is exposed during excavation work. This included a problem that durability due to wear of the bucket edge portion 121 was lost.

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た構成であり、従来例で述べたような土砂漏れやバケットエッジ部の摩耗に対する格別の対策を講じたものではない。 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 insertion recess, and the tooth plate portion is configured on one side portion of the gap setting portion. It is the structure which formed the insertion board part to perform, and it did not take the special countermeasure with respect to the earth and sand leak and abrasion of a bucket edge part which were described in the prior art example.
