Description

【０００１】
【発明の属する技術分野】
本発明は、振動転圧板付きバケットを備えたパワーシヨベルに関する。
【０００２】
【従来の技術】
従来、パワーシヨベルのバケットは、掘削と土砂等の積込みが主で、地面に対する転圧はアームにより２〜３メートル上空にバケットを上げて一気に地面にたたきつけて行つていたので、転圧効率が悪い、機械の故障が多い、作業上危険であるなどの理由から地固めは、別の作業者により、地固め用ランマーを使用して行われていたが、労力と時間がかかる欠点があった。そこでバケットに取りつけた転圧板を振動モータによって振動させる装置が実用化されたが、振動の割には転圧効果が小さい、装置が嵩高となるため、バケット容量が大幅に減少し、積込作業量が著しく低下せざるを得ず全く普及していない。
本発明者は、新たにバケット刃先面とほぼ同一平面に、又は、バケット刃先面より斜めに立ち上がった斜面に、転圧板を架設し、前記転圧板を、バケット背面板に隣接して取りつけた小型の油圧往復動振動シリンダにより、微細な振動を与えると共に、振動転圧板の架設を油圧往復動振動シリンダのピストンロッド後端と、バケット底板の下方との２ケ所で回動可能に支持すれば、前記ピストンロッドの往復動により転圧板が２度打ちする振動を発生して、大きな転圧効果とその他の特有の効果が得られることを見出し、本発明を完成した。
【０００３】
【発明が解決しようとする課題】
本発明は、杭打ち、地固め、バケット内の粘土などの附着物の完全排除、バケット刃先の振動による掘り込み、土砂等の均一混合等に特別の効果が得られる、振動転圧板付きバケットを備えたパワーシヨベルを提供するものである。
【０００４】
【課題を解決するための手段】
本発明振動転圧板付きバケットを備えたパワーシヨベルは、上記課題を達成するため、図示するように、バケット背面板１２Ａに固着したブラケット１２１Ａに回動可能に油圧往復動振動シリンダ２０Ａを取りつけ、バケット底板１１Ａに回動可能に転圧板３０Ａを取りつけ、前記油圧往復動振動シリンダ２０Ａのピストンロッド２２Ａ後端を回動可能に前記転圧板３０Ａに取りつけ、前記転圧板３０Ａをバケット刃先１４Ａとほぼ同一平面上に形成したものである。
本発明振動転圧板付きバケットを備えたパワーシヨベルは、上記課題を達成するため、図示するように、バケット背面板１２Ｂに固着したブラケット１２１Ｂに回動可能に油圧往復動振動シリンダ２０Ｂを取りつけ、バケット底板１１Ｂに回動可能に転圧板３０Ｂを取りつけ、前記油圧往復動振動シリンダ２０Ｂのピストンロッド２２Ｂ後端を回動可能に前記転圧板３０Ｂに取りつけ、前記転圧板３０Ｂをバケット刃先１４Ｂとほぼ同一平面から斜めに立ち上つた斜面に形成したものである。 本発明において、小型の油圧往復動振動シリンダは、公知のものはすべて適用できるが、本発明者は、特開平１１−６１８７９号公報及び特開２０００−２０５２０９号公報にも例示している。
また、本発明の振動転圧板は、バケット刃先方向とほぼ同一平面上に設けられるものと、バケット刃先と同一平面から立ち上がつて斜め方向の斜面に形成されたものとがあり、後者は、地面に対し通常４５度以下、好ましくは３０度〜３５度程度の角度の斜面板として取りつけられる。
【０００５】
【発明の実施の形態１】
本発明の実施の形態１が図１及び図２に示されている。
本発明実施例の振動転圧板付きバケットは、バケット１０Ａと油圧往復動振動シリンダ２０Ａと転圧板３０Ａとからなる。
バケット１０Ａは、先端に刃先１４Ａを設けた底板１１Ａ、底板１１Ａの後端に連設して立ち上がつた背面板１２Ａ、底板１１Ａの両側から連設して立ち上がった側板１３Ａ、１３Ａ、背面板１２Ａに固着した上部ブラケット１５Ａ、背面板１２Ａに固着した１対のブラケット１２１Ａ、底板１１Ａに固着した１対のブラケット１１１Ａからなつている。
油圧往復動振動シリンダ２０Ａは、シリンダ本体２１Ａと、これに固着したヘッドブラケット２１１Ａとピストンロッド２２Ａを備え、ヘッドブラケット２１１Ａは１対の背面板ブラケット１２１Ａとピン１２２Ａを介して回動可能に軸支され、ピストンロッド２２Ａ後端は後記する転圧板３０Ａに取りつけた１対のブラケット３１２Ａにピン３１３Ａを介して回動可能に軸支されている。
転圧板３０Ａは、振動板３１Ａと１対のブラケット３１１Ａと１対のブラケット３１２Ａを固着し、１対のブラケット３１１Ａは、底板１１Ａの１対のブラケット１１１Ａとピン１１２Ａを介して回動可能に軸支されている。１対のブラケット３１２Ａは、前述のように、油圧往復動振動シリンダ２０Ａのピストンロッド２２Ａの後端に、ピン３１３Ａを介して回動可能に軸支されている。また、転圧板３０Ａは、振動板３１Ａを、バケット刃先１４Ａの形成する平面とほぼ同一平面になるように形成している。
また、油圧往復動振動シリンダ２０Ａのシリンダヘッド１２１Ａのピン１２２Ａにゴムライニング、１対のブラケット１１１Ａ、１対のブラケット１２１Ａ、１対のブラケット３１１Ａ、１対のブラケット３１２Ａ等の底面に防振ゴム等を取り付けて振動緩衝構造としてもよい。さらに、油圧往復動振動シリンダ２０Ａを取り囲む背面板１２Ａ、両側面板１３Ａ等に吸音ゴム板を貼着した上に、吸音ゴム板で油圧往復動振動シリンダ２０Ａを両側面板１３Ａの縁１３１Ａを介して被覆して吸音構造としてもよい。また、この吸音構造は土砂の侵入防止にもなる。
なお、図２に示すように、バケット１０Ａの上部ブラケット１５Ａは、一方端はアーム４０とピン４１を介して回動可能に軸支され、他方端は、バケットシリンダ５０のピストンロッド５１の後端ロッドピン５１１に一方端を回動可能に軸支されたリンク６０の他方端とピン４２を介して回動可能に軸支されている。
リンク７０は、一端をアーム４０とピン７１を介して軸支され、他端をピストンロッド５１後端とピン５１１を介して回動可能に軸支されている。
従つて、地固め、杭打ちを転圧板３０Ａで行なうときは、アーム４０の回動及びバケットシリンダ５０のピストンロッド５１のストロークの調節により転圧板３０Ａを所要の向きに対面させて、油圧往復動振動シリンダ２０Ａを作動させれば、転圧板３０Ａは１分間１００〜１２００回、振幅約１０ミリメートル程度の振動を発生して、シリンダ２１Ａからピストンロッド２２Ａのストロークが出るときは、転圧板３０Ａをピン３１３Ａを支点として押し出し、ピストンロッド２２Ａのストロークが引くときは、転圧板３０Ａをピン１１２Ａを支点として押し出し、転圧板３０Ａは図上左右に２度打ちする形で振動するので、転圧板３０Ａは地固め又は杭打ちを効率よく行うことができる。また、バケット１０Ａで土砂等の積込みをしたのちは、バケット１０Ａの振動により積み込んだ土砂等を完全に排出することができる。このほか、バケット刃先の振動による掘削、バケット内の粘土等の附着積込物の排除や土砂等の均一混合等ができる。
【０００６】
【発明の実施の形態２】
本発明の実施の形態２が図３及び図４に示されている。
本発明実施例の振動転圧板付きバケットは、バケット１０Ｂと油圧往復動振動シリンダ２０Ｂと転圧板３０Ｂとからなつている。
バケット１０Ｂは、先端に刃先１４Ｂを設けた底板１１Ｂ、底板１１Ｂの後端に連設して立ち上がつた背面板１２Ｂ、底板１１Ｂの両側から連設して立ち上がった側板１３Ｂ、１３Ｂ、背面板１２Ｂに固着した上部ブラケット１５Ｂ、背面板１２Ｂに固着した１対のブラケット１２１Ｂ、底板１１Ｂに固着した１対のブラケット１１１Ｂからなつている。
油圧往復動振動シリンダ２０Ｂは、シリンダ本体２１Ｂと、これに固着したヘッドブラケット２１１Ｂ、ピストンロッド２２Ｂを備え、ヘッドブラケット２１１Ｂは１対の背面板ブラケット１２１Ｂとピン１２２Ｂを介して回動可能に軸支され、ピストンロッド２２Ｂ後端は、後記する転圧板３０Ｂに取りつけた１対のブラケット３１２Ｂにピン３１３Ｂを介して回動可能に軸支されている。
転圧板３０Ｂは、バケット刃先１４Ｂの形成する平面と約３０度乃至３５度の角度で斜め方向に立ち上がつている振動斜面板３１Ｂと、１対のブラケット３１１Ｂと１対のブラケット３１２Ｂを固着し、１対のブラケット３１１Ｂは、底板１１Ｂの１対のブラケット１１１Ｂとピン１１２Ｂを介して回動可能に軸支されている。１対のブラケット３１２Ｂは、前述のように、油圧往復動振動シリンダ２０Ｂのピストンロッド２２Ｂの後端に、ピン３１３Ｂを介して回動可能に軸支されている。
振動緩衝構造及び吸音構造を加えるときは、発明の実施の形態１と同様であるので詳細説明を省略する。
なお、バケット１０Ｂの上部ブラケット１５Ｂは、図４に示すように、一方端はアーム４０とピン４１を介して回動可能に軸支され、他方端は、バケットシリンダ５０のピストンロッド５１の後端のロッドピン５１１に一方端を回動可能に軸支されたリンク６０の他方端とピン４２を介して回動可能に軸支されている。
リンク７０は、一端をアーム４０とピン７１を介して軸支され、他端をピストンロッド５１後端とピン５１１を介して回動可能に軸支されている。
従つて、地固め、杭打ちを転圧板３０Ｂで行なうときは、アーム４０の回動及びバケットシリンダ５０のピストンロッド５１のストロークの調節により、転圧板３０Ｂを所要の斜面の向きに対面させて、油圧往復動振動シリンダ２０Ｂを作動させれば、発明の実施の形態１と同様に効率よく行うことができ、そのほかの作業も発明の実施の形態１と同様にできるが、本実施例の場合、転圧板３０Ｂがバケット刃先１４Ｂと同一平面になく斜め方向の斜面を形成しているので、バケット刃先１４Ｂが邪魔にならず、法面の地固めに最適で、運転席からも転圧状況がよく観察できる。
【０００７】
【発明の効果】
本発明の振動転圧板付きバケットを備えたパワーシヨベルは、幅狭い溝堀りや溝底の地固め、法面などの斜面の地固めを、微小な振幅で転圧板を振動させるだけで行え、また、杭打ち、粘土質の粘着物積み出し、バケット刃先による掘削、土砂等の均一混合等も転圧板を僅かな振幅で振動させれば済み、作業能率の向上及び作業安全性の確保に大きく寄与できる。

BACKGROUND OF THE INVENTION
The present invention relates to a power shovel including a bucket with a vibration rolling plate.
[0002]
[Prior art]
Conventionally, power shovel buckets are mainly excavated and loaded with earth and sand, etc. Rolling pressure against the ground is raised by lifting the bucket 2 to 3 meters above the arm and hitting the ground at once, so the rolling efficiency is poor However, consolidation has been performed by another worker using a consolidation rammer for reasons such as many machine failures and work hazards, but has the disadvantage of requiring labor and time. Therefore, a device that vibrates the rolling plate attached to the bucket with a vibration motor was put into practical use. However, the rolling effect is small for the vibration, and the device becomes bulky. The amount is inevitably reduced and is not popular at all.
The present inventor newly installed a compaction plate on a substantially same plane as the bucket blade edge surface or on an inclined surface rising obliquely from the bucket blade edge surface, and attached the compaction plate adjacent to the bucket back plate. If the hydraulic reciprocating vibration cylinder gives fine vibrations and the vibration rolling plate is supported rotatably at two places, the rear end of the piston rod of the hydraulic reciprocating vibration cylinder and the bottom of the bucket bottom plate, The present inventors have found that a large rolling effect and other unique effects can be obtained by generating a vibration in which the rolling plate strikes twice by the reciprocating motion of the piston rod.
[0003]
[Problems to be solved by the invention]
The present invention includes a bucket with a vibration compaction plate, which has special effects for pile driving, consolidation, complete removal of attachments such as clay in the bucket, excavation by vibration of the bucket blade edge, uniform mixing of earth and sand, etc. A power shovel is provided.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned problem, the power shovel equipped with the bucket with the vibration rolling plate of the present invention attaches the hydraulic reciprocating vibration cylinder 20A to the bracket 121A fixed to the bucket back plate 12A so as to be rotatable, as shown in the drawing, A rolling plate 30A is rotatably attached to 11A, and a piston rod 22A rear end of the hydraulic reciprocating vibration cylinder 20A is rotatably attached to the rolling plate 30A, and the rolling plate 30A is substantially flush with the bucket blade edge 14A. Is formed.
In order to achieve the above-mentioned problem, the power shovel having the bucket with the vibration rolling plate of the present invention attaches the hydraulic reciprocating vibration cylinder 20B to the bracket 121B fixed to the bucket back plate 12B so as to be rotatable, as shown in the figure, 11B is rotatably attached to the compaction plate 30B, and the rear end of the piston rod 22B of the hydraulic reciprocating vibration cylinder 20B is pivotably attached to the compaction plate 30B. The compaction plate 30B is substantially flush with the bucket blade edge 14B. It is formed on a slope that rises diagonally. In the present invention, all known small hydraulic reciprocating vibration cylinders can be applied, but the present inventor also exemplifies in Japanese Patent Laid-Open Nos. 11-61879 and 2000-205209.
In addition, the vibration rolling plate of the present invention is provided on substantially the same plane as the bucket blade edge direction, and is formed on an inclined surface that rises from the same plane as the bucket blade edge, It is usually mounted as a sloped plate with an angle of 45 degrees or less, preferably about 30 to 35 degrees with respect to the ground.

It is supported. As described above, the pair of brackets 312A is pivotally supported on the rear end of the piston rod 22A of the hydraulic reciprocating vibration cylinder 20A via a pin 313A. Further, the rolling plate 30A is formed so that the vibration plate 31A is substantially flush with the plane formed by the bucket blade edge 14A.
Further, a rubber lining is provided on the pin 122A of the cylinder head 121A of the hydraulic reciprocating vibration cylinder 20A, a vibration isolating rubber is provided on the bottom surface of the pair of brackets 111A, the pair of brackets 121A, the pair of brackets 311A, the pair of brackets 312A, and the like. It is good also as a vibration buffer structure by attaching. Further, a sound absorbing rubber plate is attached to the back plate 12A, both side plates 13A and the like surrounding the hydraulic reciprocating vibration cylinder 20A, and the hydraulic reciprocating vibration cylinder 20A is covered with the sound absorbing rubber plates via the edges 131A of the both side plates 13A.

A second embodiment of the present invention is shown in FIGS.
The bucket with vibration rolling plate according to the embodiment of the present invention includes a bucket 10B, a hydraulic reciprocating vibration cylinder 20B, and a rolling plate 30B.
The bucket 10B includes a bottom plate 11B provided with a cutting edge 14B at the front end, a back plate 12B standing and connecting to the rear end of the bottom plate 11B, side plates 13B and 13B rising and connecting from both sides of the bottom plate 11B. The upper bracket 15B is fixed to 12B, the pair of brackets 121B is fixed to the back plate 12B, and the pair of brackets 111B is fixed to the bottom plate 11B.
The hydraulic reciprocating vibration cylinder 20B includes a cylinder body 21B, a head bracket 211B fixed to the cylinder body 21B, and a piston rod 22B. The head bracket 211B is pivotally supported via a pair of back plate brackets 121B and pins 122B. The rear end of the piston rod 22B is pivotally supported via a pin 313B on a pair of brackets 312B attached to a rolling plate 30B described later.
The rolling plate 30B fixes the vibration slope plate 31B, which rises obliquely at an angle of about 30 to 35 degrees with the plane formed by the bucket blade edge 14B, the pair of brackets 311B, and the pair of brackets 312B. The pair of brackets 311B are pivotally supported via a pair of brackets 111B and a pin 112B on the bottom plate 11B.

Therefore, when consolidating and pile driving with the rolling plate 30B, the rolling plate 30B is faced in the direction of the required slope by rotating the arm 40 and adjusting the stroke of the piston rod 51 of the bucket cylinder 50, so that the hydraulic pressure is increased. If the reciprocating vibration cylinder 20B is operated, it can be performed efficiently as in the first embodiment of the invention, and other operations can be performed in the same manner as in the first embodiment of the invention. Since the pressure plate 30B is not coplanar with the bucket blade edge 14B but forms an oblique slope, the bucket blade edge 14B does not get in the way, is ideal for consolidation of the slope, and can be observed well from the driver's seat. .
[0007]
【The invention's effect】
The power shovel equipped with the bucket with the vibration compaction plate of the present invention can perform narrow groove digging, consolidation of the groove bottom, consolidation of slopes such as slopes, etc. by simply vibrating the compaction plate with a minute amplitude. It is also necessary to vibrate clay compact adhesives, excavation with bucket blade tips, uniform mixing of earth and sand, etc., if the rolling plate is vibrated with a slight amplitude, which can greatly contribute to improvement of work efficiency and safety of work.
