Description

【0001】
【発明の属する技術分野】
本発明は、パワーショベルなどの掘削作業機械の機械本体に対して前後方向に揺動するアームにバケットを取付ける構造に関する。
【0002】
【従来の技術】
パワーショベルとしては例えば図1に示すように、走行体1に機械本体2を旋回可能に取付け、この機械本体2にブーム3をブームシリンダ4で上下方向に揺動自在に取付け、そのブーム3にアーム5をアームシリンダ6で前後方向に揺動自在に取付け、このアーム5にバケット7をバケットシリンダ8で前後揺動自在に取付けたものが知られている。
【0003】
前述のパワーショベルにおいては、バケット7をアーム5に第1のピン9で連結すると共に、バケット7をプッシュリンク10に第2のピン11で連結してバケット7をアーム5に取付けており、これによってバケットシリンダ8のピストンロッド12を伸縮することでバケットリンク13、プッシュリンク10を介してバケット7がアーム5に対して前後方向に揺動する。
【0004】
このようなパワーショベルはバケット7による掘削作業が主な作業であるが、そのバケット7を外してブレーカなどのアタッチメントをアーム5に取付けてブレーカ作業などの補助作業を行なうことがある。
【0005】
第1のピン9と第2のピン11を抜き出しすればアーム5からバケット7を外すことができるし、第1のピン9と第2のピン11を挿入すればアーム5にバケット7を取付けできるが、第1のピン9、第2のピン11を挿入するにはアーム5、プッシュリンク10のピン孔とバケット7のピン孔を一致させる必要があり、そのピン孔が一致するように位置決めする作業が面倒である。
【0006】
このことを解消するために、実開平6−57953号公報に示すバケットの取付構造が提案されている。この取付構造は図2に示すようにアーム側取付部14とバケット取付部15を備えた連結部材16のアーム側取付部14をアーム5とプッシュリンク10にピン17によりそれぞれ取付け、バケット取付部15のピン孔18とバケット7のピン孔19に第1のピンを挿入し、バケット7に設けた第2のピン19aをアーム取付部15の切欠部20に係合してバケット7をアーム5に取付ける構造である。
【0007】
【発明が解決しようとする課題】
実開平6−57953号公報に示すバケットの取付構造であると、一本のピンを挿入、抜き出しすればバケットを取付け、外しできるが、バケット7の取付け位置がバケット取付部15の切欠部20とピン17との間の寸法Sだけ図1に示す通常の取付構造に対してずれるので、図3に示すように、アーム5を後方に揺動状態でバケット7を前後に揺動する時にバケット7がブーム3に干渉することがある。
【0008】
そこで、本発明は前述の課題を解決できるようにしたバケットの取付構造を提供することを目的とする。
【0009】
【課題を解決するための手段及び作用、効果】
第1の発明は、アーム5に連結したバケットリンク13にプッシュリンク10の一端部を連結し、
バケット7に一対の取付用ブラケット35を固着し、この一対の取付用ブラケット35に、第1ピン51が挿通する第1ピン孔37と第2ピン53が挿通する第2ピン孔38をそれぞれ形成し、
前記第1ピン51に係脱自在なフック45,第3ピン孔42,第4ピン孔43を有する一対の取付用リンク40を連杆41で間隔を置いて固着し、この一対の取付用リンク40を、第3ピン孔42に挿通した第3ピン55で前記アーム5に連結し、
前記取付用リンク40の第4ピン孔43に嵌合した筒軸46を前記プッシュリンク10の他端部に形成した第5ピン孔49に嵌挿して取付用リンク40とプッシュリンク10を連結し、前記一対の取付用リンク40のフック45を第1ピン51にそれぞれ係合し、前記一対の取付用ブラケット35の第2ピン孔38と前記筒軸46に亘って第2ピン53を挿通して一対の取付用リンク40とプッシュリンク10を一対の取付用ブラケット35に連結したことを特徴とするバケットの取付構造である。
【0010】
第1の発明によれば、取付用リンク40のフック45を第1ピン51に係合し、その状態で取付用リンク40又はバケット7を揺動することで第2ピン53を筒軸46に挿通して取付用リンク40、プッシュリンク10をバケット7に連結できる。
【0011】
これによって、アーム5にバケット7を簡単に取付けできる。
【0012】
また、筒軸46から第2ピン53を抜き出してアーム5からバケット7を分離した時にプッシュリンク10と取付用リンク40が筒軸46で連結されているから、バケット7の取付け、外し作業がより簡単となる。
【0013】
また、取付用リンク40のフック45が第1ピン51に係合し、取付用リンク40とプッシュリンク10が同一の第2ピン53でバケット7に連結してあるから、通常の取付構造とほぼ同一となる。これによって、アーム5を後方に揺動してバケット7を前後に揺動してもバケット7がブームに干渉することがない。
【0016】
の発明は、第の発明における連杆41と他方の取付用リンク40をボルト41aで着脱自在に連結し、筒軸46を一方の取付用リンク40の第4ピン孔43に嵌合して固着したバケットの取付構造である。
【0017】
の発明によれば、ボルト41aを弛めて他方の取付用リンク40を外すことで一対の取付用リンク40とプッシュリンク10を連結したり、分離したりできる。
【0018】
【発明の実施の形態】
図4はアームとバケットの分解斜視図であり、アーム5の先端部にはアーム側ピン孔30が幅方向に貫通して形成してあり、このアーム側ピン孔30よりも基端寄りにバケットリンク用ピン孔31が形成してある。
【0019】
バケット7はほぼU字状の底板32と一対の側板33により成るバケット本体34と、このバケット本体34の背面側に取付けた一対の取付用ブラケット35とを備え、バケット本体34の先端縁に掘削刃36が取付けてある。前記各取付用ブラケット35には第1ピン孔37と第2ピン孔38が形成され、各取付用ブラケット35の外面における第1・第2ピン37,38の周縁部には筒状のボス部39がそれぞれ設けてある。
【0020】
一対の取付用リンク40,40は連杆41で所定の間隔を置いて平行に連結してある。この取付用リンク40には第3ピン孔42と第4ピン孔43が形成され、その第3ピン孔42の周縁部に筒状のボス部44が設けてあり、取付用リンク40の第3ピン孔42寄りにフック45が一体的に設けてある。
【0021】
前記一方の取付用リンク40の内面には筒軸46を備えたプレート47がボルト48で固着され、その筒軸46は第4ピン孔43に嵌合している。前記プッシュリンク10は第5ピン孔49と第6ピン孔50を有し、その第5ピン孔49に前記筒軸46が回転可能に挿入するようにしてある。
【0022】
前記第1ピン孔37には第1ピン51が挿入されてボルト52で抜け止めされる。前記第2ピン孔38には第2ピン53が挿入されて抜け止めピン54で抜け止めされる。
【0023】
図5と図6に示すように、アーム側ピン孔30と第3ピン孔42に第3ピン55が挿入されて取付用リンク40がアーム5に揺動自在に連結してある。取付用リンク40のフック45が第1ピン51に係合している。第2ピン53は筒軸46を貫通して他方の取付用リンク40の第4ピン孔43に嵌合して、一対の取付用リンク40にプッシュリンク10を第2ピン53で揺動自在に連結している。
【0024】
前記アーム5のバケットリンク用ピン孔31にバケットリンク13が第4ピン56で揺動自在に連結され、バケットリンク13とプッシュリンク10か第5ピン57で揺動自在に連結されている。
【0025】
次にバケットをアームに取付ける作業手順を説明する。
図7に示すようにバケット7を地面に置く。アーム5にはバケットリンク13、プッシュリンク10、取付用リンク40を取付ける。この時、取付用リンク40に固着した筒軸46がプッシュリンク10の第5ピン孔49に嵌合している。
【0026】
前述の状態でアーム5を揺動し取付用リンク40のフック45を第1ピン51に係合し、アーム5を上方に移動してバケット7を地面から持ち上げる。バケットシリンダ8を伸長して筒軸46を第2ピン孔38に合致し、第2ピン53を第2ピン孔38、筒軸46、他方の取付用リンク40の第4ピン孔43に嵌合してバケット7と取付用リンク40を連結する。
【0027】
なお、前述の筒軸46と第2ピン孔38を合せる時に微操作が必要な場合には、バケット7を作業者が手でゆすりながら第2ピン53を挿入すれば良い。
【0028】
バケット7を外す時には第2ピン53を抜き出してバケット7と取付用リンク40を分離し、バケット7を地面に置いてフック45を第1ピン51から離脱すれば良い。この時、第2ピン53を抜いても取付用リンク40とプッシュリンク10が連結された状態となり、バケットを簡単に外すことができるし、バケット7を簡単に取付けできる。
【0029】
図8と図9は第2の実施の形態を示し、一対の取付用ブラケット35の内側面に一対の取付用リンク40を位置させ、その一対の取付用リンク40の第4ピン孔43に筒軸46の両端部を嵌合して取付用リンク40とプッシュリンク10を連結してある。
【0030】
このように構成すれば、一対の取付用リンク40が左右対称となるし、筒軸46で連結されるからバケット7を安定して作動できる。
【0031】
図10は取付用リンク40の他の実施の形態を示し、一方の取付用リンク40に連杆41を固着し、この連杆41に他方の取付用リンク40をボルト41aで固着して分割可能タイプとしてある。筒軸46は一方の取付用リンク40の第4ピン孔43に嵌合して固着してある。このようにすれば、他方の取付用リンク40を外すことでプッシュリンク10と取付用リンク40を連結したり、分離できる。

BACKGROUND OF THE INVENTION
The present invention relates to a structure in which a bucket is attached to an arm that swings in the front-rear direction with respect to a machine body of an excavation work machine such as a power shovel.
[0002]
[Prior art]
As a power shovel, for example, as shown in FIG. 1, a machine main body 2 is pivotably attached to a traveling body 1, and a boom 3 is attached to the machine main body 2 by a boom cylinder 4 so as to be swingable in a vertical direction. It is known that an arm 5 is attached to an arm cylinder 6 so as to be swingable back and forth, and a bucket 7 is attached to the arm 5 so as to be swingable back and forth using a bucket cylinder 8.
[0003]
In the above-described excavator, the bucket 7 is connected to the arm 5 by the first pin 9, and the bucket 7 is connected to the push link 10 by the second pin 11 to attach the bucket 7 to the arm 5. As a result, the bucket 7 swings back and forth with respect to the arm 5 via the bucket link 13 and the push link 10 by expanding and contracting the piston rod 12 of the bucket cylinder 8.
[0004]
Such a power shovel is mainly excavated by the bucket 7, but there are cases where the bucket 7 is removed and an attachment such as a breaker is attached to the arm 5 to perform auxiliary work such as breaker work.
[0005]
The bucket 7 can be removed from the arm 5 by extracting the first pin 9 and the second pin 11, and the bucket 7 can be attached to the arm 5 by inserting the first pin 9 and the second pin 11. However, in order to insert the first pin 9 and the second pin 11, it is necessary to match the pin hole of the arm 5 and push link 10 with the pin hole of the bucket 7, and positioning is performed so that the pin holes match. Work is troublesome.
[0006]
In order to solve this problem, a bucket mounting structure shown in Japanese Utility Model Laid-Open No. 6-57953 has been proposed. As shown in FIG. 2, the mounting structure is such that the arm side mounting portion 14 of the connecting member 16 provided with the arm side mounting portion 14 and the bucket mounting portion 15 is mounted on the arm 5 and the push link 10 by pins 17 respectively. The first pin is inserted into the pin hole 18 and the pin hole 19 of the bucket 7, and the second pin 19 a provided on the bucket 7 is engaged with the notch portion 20 of the arm attachment portion 15, so that the bucket 7 is attached to the arm 5. It is a structure to install.
[0007]
[Problems to be solved by the invention]
In the bucket mounting structure shown in Japanese Utility Model Publication No. 6-57953, the bucket can be attached and detached by inserting and removing a single pin. Since the dimension S between the pin 17 and the pin 17 is shifted from the normal mounting structure shown in FIG. 1, the bucket 7 is swung back and forth while the arm 5 is swung back and forth as shown in FIG. May interfere with the boom 3.
[0008]
Therefore, an object of the present invention is to provide a bucket mounting structure that can solve the above-described problems.
[0009]
[Means, functions and effects for solving the problems]
1st invention connects the one end part of the push link 10 to the bucket link 13 connected with the arm 5,
A pair of mounting brackets 35 are fixed to the bucket 7, and a first pin hole 37 through which the first pin 51 is inserted and a second pin hole 38 through which the second pin 53 is inserted are formed in the pair of mounting brackets 35, respectively. And
A pair of mounting links 40 each having a hook 45, a third pin hole 42, and a fourth pin hole 43, which can be freely engaged with and disengaged from the first pin 51, are fixed at intervals with a linkage 41, and the pair of mounting links. 40 is connected to the arm 5 with a third pin 55 inserted into the third pin hole 42,
The cylindrical shaft 46 fitted into the fourth pin hole 43 of the mounting link 40 is inserted into a fifth pin hole 49 formed at the other end of the push link 10 to connect the mounting link 40 and the push link 10. The hooks 45 of the pair of mounting links 40 are respectively engaged with the first pins 51, and the second pins 53 are inserted through the second pin holes 38 of the pair of mounting brackets 35 and the cylindrical shaft 46. Thus, the bucket mounting structure is characterized in that a pair of mounting links 40 and a push link 10 are connected to a pair of mounting brackets 35.
[0010]
According to the first invention, the hook 45 of the attachment link 40 is engaged with the first pin 51, and the attachment pin 40 or the bucket 7 is swung in this state, whereby the second pin 53 is attached to the cylinder shaft 46. The attachment link 40 and the push link 10 can be connected to the bucket 7 by being inserted.
[0011]
Thereby, the bucket 7 can be easily attached to the arm 5.
[0012]
Further, when the second pin 53 is extracted from the cylindrical shaft 46 and the bucket 7 is separated from the arm 5, the push link 10 and the mounting link 40 are connected by the cylindrical shaft 46, so that the bucket 7 can be attached and removed more. It will be easy.
[0013]
Further, the hook 45 of the mounting link 40 engages with the first pin 51, and the mounting link 40 and the push link 10 are connected to the bucket 7 by the same second pin 53, so that it is almost the same as a normal mounting structure. It will be the same. Thereby, even if the arm 5 is swung back and the bucket 7 is swung back and forth, the bucket 7 does not interfere with the boom.
[0016]
In the second invention, the linkage 41 in the first invention and the other mounting link 40 are detachably connected by a bolt 41 a, and the cylindrical shaft 46 is fitted into the fourth pin hole 43 of the one mounting link 40. It is the attachment structure of the bucket which adheres.
[0017]
According to the second invention, the pair of attachment links 40 and the push links 10 can be connected or separated by loosening the bolts 41a and removing the other attachment links 40.
[0018]
