It is designed to be closed and tightened.

また、従来においては、特許文献２（特開平９−１７７１１４号公報）に記載され、同様に、油圧ショベルを用いて製造する方法も知られている。これは、油圧ショベルのアームに専用のバケット装置を取り付け、このバケット装置により、土嚢袋に土類を充填するものである。
図１１に示すように、バケット装置Ｓａは、第１枠部材３と第２枠部材４とを備え、第２枠部材４には、掘削刃４ａが設けられ、第１枠部材３は、第２枠部材４の開口部の内面に対して、外面がほぼ摺接可能に形成され、第２枠部材４に対してピンで連結されている。第１枠部材３と第２枠部材４とは、駆動手段として左右に設けた油圧シリンダ５により開帳自在に形成されている。第１枠部材３の左右中央部には外側に向かってＬ字形の係止部材３ａがそれぞれ設けられている。 Conventionally, it is described in Patent Document 2 (Japanese Patent Laid-Open No. 9-177114), and similarly, a method of manufacturing using a hydraulic excavator is also known. In this method, a dedicated bucket device is attached to an arm of a hydraulic excavator, and the sandbag is filled with earth using this bucket device.
As shown in FIG. 11, the bucket apparatus Sa includes a first frame member 3 and a second frame member 4, and the second frame member 4 is provided with a digging blade 4 a, and the first frame member 3 is a first frame member 3. The outer surface is formed so as to be slidable with respect to the inner surface of the opening of the two frame member 4 and is connected to the second frame member 4 with a pin. The first frame member 3 and the second frame member 4 are formed to be openable by hydraulic cylinders 5 provided on the left and right sides as drive means. L-shaped locking members 3a are respectively provided on the left and right central portions of the first frame member 3 toward the outside.

この油圧ショベル用バケット装置Ｓを用いて土嚢を製造する際は、先ず、第１枠部材３を開帳し、土嚢袋Ｆを開き、第１枠部材３にその開口を嵌め、締め紐の両端は係止部材３ａの外側に掛け回す。次に、第１枠部材３を閉めて、第１枠部材３と第２枠部材４とにより土嚢袋Ｆの開口部を挟持する。

特許第２７３９３０７号公報Japanese Patent No. 2739307 特開平９−１７７１１４号公報JP 9-177114 A

ところで、上記従来の前者の方法にあっては、油圧ショベルのバケット１に入れられる土類を複数の土嚢袋Ｆに落とし込むので、ならし棒２で開口から溢れた土類を水平にならしてはいるものの、土嚢袋Ｆへ入る量が必ずしも一定ではなく、不均一になってしまい、土嚢の品質にバラツキが生じてしまうという問題があった。また、逐一ならし棒２で土類を水平にならしているので、それだけ、作業工数が多くなり、製造効率が悪いという問題もある。   By the way, in the former former method, since the earth put in the bucket 1 of the hydraulic excavator is dropped into a plurality of sandbags F, the earth overflowing from the opening is leveled with the leveling bar 2 horizontally. However, there was a problem that the amount entering the sandbag F was not necessarily constant and became non-uniform, resulting in variations in the quality of the sandbag. Further, since the earth is leveled with the leveling rod 2 one by one, there is a problem that the number of work steps increases and the production efficiency is poor.

一方、上記後者の方法にあっても、１袋ずつバケット装置Ｓａに装着して土類の掘削により、土類を充填しているが、掘削毎の土類の量が一定ではないので、前者の土嚢と同様に、土嚢袋Ｆへ入る土類の量が必ずしも一定ではなく、不均一になってしまい、土嚢の品質にバラツキが生じてしまうという問題があった。また、土類の量を一定化しようとすると、満杯時期を見計らわなければならず、それだけ作業が煩雑になってしまうし、一つずつ土嚢を製造するので、製造効率が悪くなってしまうという問題もある。   On the other hand, even in the latter method, soil is filled by excavating the earth by attaching it to the bucket device Sa one bag at a time. However, since the amount of earth per excavation is not constant, the former As in the case of the sandbag, the amount of soil entering the sandbag bag F is not necessarily constant, and it becomes non-uniform, resulting in a variation in the quality of the sandbag. Also, if you try to keep the amount of soil constant, you will have to wait for the full time, which will complicate the work and produce the sandbags one by one, resulting in poor production efficiency. There is also a problem.

本発明は上記の問題点に鑑みて為されたもので、土類をその量をある程度計量してすくい取ることができるようにして、土嚢袋へ入る土類の量を一定化し、土嚢の均一化を図ることができるようにするとともに、複数の土嚢袋に土類を同時に充填できるようにして製造効率の向上を図った油圧ショベル用バケット装置を提供することを目的とする。   The present invention has been made in view of the above-mentioned problems, so that the amount of soil can be scraped by measuring its amount to some extent, the amount of soil entering the sandbag is made constant, and the sandbag is uniform. It is an object of the present invention to provide a bucket device for a hydraulic excavator that can improve the manufacturing efficiency by simultaneously filling a plurality of sandbags with earth.

このような目的を達成するための本発明の油圧ショベル用バケット装置は、油圧ショベルのアームに回動可能かつ着脱可能に連結され、開放状態で列設された複数の土嚢袋に土類を充填する為の油圧ショベル用バケット装置において、一端に底部を有し他端に開口を有して形成され土類が入れられる筒体をその軸線を平行にして複数列設してなる本体と、該本体に設けられ上記アームに連結される連結部とを備えて構成されている。   In order to achieve such an object, the bucket device for a hydraulic excavator of the present invention is rotatably and detachably connected to the arm of the hydraulic excavator, and is filled with a plurality of sandbags arranged in an open state. In a bucket device for a hydraulic excavator for carrying out, a main body formed by arranging a plurality of cylinders having a bottom at one end and an opening at the other end into which earth is placed, And a connecting portion provided on the main body and connected to the arm.

この油圧ショベル用バケット装置を用いて、土嚢を製造する場合は、土嚢袋をスタンドなどに支持し開放状態で列設しておく。一方、油圧ショベルにおいては、予め、アームにバケット装置の連結部を連結してその本体を取り付けておく。
この状態で、油圧ショベルのアームを操作するとともにアームに対してバケット装置を回動操作し、バケット装置の本体の筒体を土類に差し入れてこの筒体で土類をすくい取って筒体内に土類を入れる。
次に、油圧ショベルのアームを操作し、土嚢袋の開口に、本体の各筒体の開口を近づけ、油圧ショベルのアームに対してバケット装置を回動操作し、本体の筒体に入れられた土類を土嚢袋に落とし込んで充填していく。その後に、土嚢袋の開口を締め紐などで締め、土嚢を完成させる。 When producing a sandbag using this hydraulic shovel bucket device, the sandbag is supported by a stand or the like and arranged in an open state. On the other hand, in a hydraulic excavator, a connecting portion of a bucket device is connected to an arm in advance and a main body thereof is attached.

更に、各筒体のすくい取った量は一定化されて略均一化されているので、各土嚢袋へ入る量が略一定になり、土嚢の品質にバラツキが生じなくなる。
更にまた、本体の回動により複数の土嚢袋に土類が同時に充填されるので、土嚢の製造効率を向上させることができる。 In this case, when scraping the soil with the bucket device and putting the soil into the cylinder, the soil can be divided into each cylinder and scooped. However, the amount of the soil put into each cylinder is measured. Therefore, the amount of earth filling the sandbag is made constant.
Furthermore, since the amount of scooping of each cylinder is made constant and substantially uniform, the amount entering each sandbag becomes substantially constant, and the quality of the sandbag does not vary.
Furthermore, since the earth is simultaneously filled in the plurality of sandbag bags by the rotation of the main body, the manufacturing efficiency of the sandbag can be improved.

また、必要に応じ、上記各筒体を所定ピッチで列設した構成としている。土嚢袋を予めピッチに合わせて配置しておくことができ、土嚢袋の配置が容易になるとともに、土嚢袋に土類を充填しやすくなる。
更に、必要に応じ、上記筒体の開口を該筒体の軸線に対して傾斜形成し該開口の一部に尖状部を形成している。
筒体に土類を入れる際に、筒体の開口の尖状部が尖っているので、土類に差し入れやすくなり、それだけ、土類をすくいとり易くなる。また、土類を土嚢袋に入れる際も、筒体の尖状部を土嚢袋の開口に差し入れ易く、そのため、土類を土嚢袋に確実に充填し易くなり、それだけ、土嚢の製造効率が向上させられる。 Moreover, it is set as the structure which arranged each said cylinder at a predetermined pitch as needed. The sandbag can be arranged in advance in accordance with the pitch, which facilitates the placement of the sandbag and easily fills the sandbag with soil.
Furthermore, if necessary, the opening of the cylindrical body is inclined with respect to the axis of the cylindrical body, and a pointed portion is formed in a part of the opening.
When the earth is put into the cylinder, the pointed portion of the opening of the cylinder is sharp, so that it is easy to insert the earth into the earth, and it is easier to scoop up the earth. In addition, when putting earth into the sandbag, it is easy to insert the pointed part of the cylinder into the opening of the sandbag, so it is easier to reliably fill the sandbag with earth, and the efficiency of sandbag production is improved accordingly. Be made.

以上説明したように、本発明の油圧ショベル用バケット装置によれば、一端に底部を有し他端に開口を有し土類が入れられる筒体をその軸線を平行にして複数列設してなる本体と、本体に設けられアームに連結される連結部とを備えたので、各土嚢に入れる土類をある程度計量して各筒体毎にすくいとることができ、土嚢袋へ入る土類の量を一定化でき、土嚢の均一化を図ることができる。また、複数の土嚢袋に同時に充填できるようになり、土嚢の製造効率を向上させることができる。
また、各筒体を所定ピッチで列設した場合には、土嚢袋の配置を容易にすることができるとともに、土嚢袋に土類を充填し易くすることができる。
更に、筒体の開口を筒体の軸線に対して傾斜形成し開口の一部に尖状部を形成した場合には、筒体の尖状部を土類に差し入れて土類をすくいとり易くなるとともに、土類を土嚢袋に入れる際も、筒体の尖状部を土嚢袋の開口に差し入れて土類を土嚢袋に充填し易くなり、それだけ、土嚢の製造効率が向上させられる。 As explained above, according to the bucket device for a hydraulic excavator of the present invention, a plurality of cylinders having a bottom portion at one end and an opening at the other end and containing earth are arranged in parallel with the axis line thereof. The main body and the connecting portion provided on the main body and connected to the arm, so that the soil put in each sandbag can be measured to some extent and can be scooped for each cylinder, The amount can be made constant and the sandbag can be made uniform. In addition, a plurality of sandbag bags can be filled at the same time, and the manufacturing efficiency of the sandbag can be improved.
Further, when the cylinders are arranged at a predetermined pitch, the sandbag bags can be easily arranged, and the sandbag bags can be easily filled with earth.
Furthermore, when the opening of the cylinder is inclined with respect to the axis of the cylinder and the pointed portion is formed on a part of the opening, the pointed portion of the cylinder is inserted into the earth to easily scoop the earth. In addition, when putting earth into the sandbag, it becomes easier to fill the sandbag with the pointed portion of the cylinder into the opening of the sandbag, and the production efficiency of the sandbag is improved accordingly.

In this case, the opening 41 of the sandbag F is folded and locked to each locking ring 42 of the stand 40.
On the other hand, in the excavator B, the excavator bucket device S is attached to the arm 12 by connecting the connecting portion 30 in advance. In the operation of the hydraulic excavator bucket device S, when the hydraulic cylinder 14 provided on the upper side of the arm 12 is operated from the cab provided on the base 10 of the hydraulic excavator B, the link 15 is hydraulically connected via the link connection hole 36. Since the rear side of the main body 20 of the shovel bucket apparatus S is pushed or pulled, the main body 20 rotates so that the opening 23 of the main body 20 faces upward or downward about the rotation shaft 37 inserted through the arm connection hole 35. Be made.

そして、油圧ショベルＢを移動させ、図６及び７に示すように、油圧ショベルＢのブーム１１，アーム１２及び本体２０を回動させる油圧シリンダ１３，１４を操作し、筒体２２を土類に差し入れて本体２０に土類をすくいとる。この際、開口２３を尖らせた尖状部２４があるので、土類に筒体２２を差し入れ易くなる。また、筒体２２の開口２３が筒体２２の軸線ｘに対して傾斜形成されているので、土類をすくい取り易くできる。この場合、土類は各筒体２２に分割してすくいとられるが、筒体２２の容積が充填可能な土類の容積と略同じに形成されているので、各筒体２２に入れられる土類の量が計量させられ、そのため、土嚢袋Ｆに充填する土類の量が一定化される。   Then, the hydraulic excavator B is moved, and the hydraulic cylinders 13 and 14 for rotating the boom 11, the arm 12 and the main body 20 of the hydraulic excavator B are operated as shown in FIGS. Insert and scoop earth into the body 20. At this time, since there is a pointed portion 24 with the opening 23 sharpened, the cylindrical body 22 can be easily inserted into the earth. Moreover, since the opening 23 of the cylindrical body 22 is inclined with respect to the axis line x of the cylindrical body 22, it is possible to easily scoop up the soil. In this case, the soil is scooped up into each cylinder 22, but the volume of the cylinder 22 is formed to be approximately the same as the volume of the earth that can be filled, so the soil that is put into each cylinder 22. The amount of soil is weighed, so that the amount of soil filled in the sandbag F is made constant.

次にまた、図７乃至図９に示すように、筒体２２の開口２３を上に向けた状態で、基体１０をスタンド４０のある方向に旋回させ、筒体２２の開口２３をスタンド４０に係止された土嚢袋Ｆの開口４１に近づけて、アーム１２に対してバケット装置Ｓを回動操作し、本体２０の筒体２２にすくいとられた土類を土嚢袋Ｆに充填していく。この場合、筒体２２の開口２３の尖状部２４が尖っているので、土嚢袋Ｆの開口４１に差し入れ易く、そのため、土類を土嚢袋Ｆに確実に充填し易くなり、それだけ、土嚢の製造効率が向上させられる。また、この際、各筒体２２のすくい取った量は略均一化されているので、各土嚢袋Ｆへ入る量が略一定になり、土嚢の品質にバラツキが生じなくなる。また、本体２０が、複数の土嚢袋Ｆに同時に充填するので、土嚢の製造効率を向上させることができる。
その後に、フック２７を利用して土嚢袋Ｆの開口４１を締め紐で締め、スタンド４０から取り外し、土嚢を完成させる。 Next, as shown in FIGS. 7 to 9, the base 10 is turned in a direction where the stand 40 is located with the opening 23 of the cylindrical body 22 facing upward, and the opening 23 of the cylindrical body 22 is moved to the stand 40. The bucket device S is rotated with respect to the arm 12 close to the locked opening 41 of the sandbag bag F, and the soil bag scooped by the cylindrical body 22 of the main body 20 is filled into the sandbag bag F. . In this case, since the pointed portion 24 of the opening 23 of the cylindrical body 22 is sharp, it is easy to insert it into the opening 41 of the sandbag F, and therefore, it is easy to reliably fill the sandbag F with soil, and that much of the sandbag. Manufacturing efficiency is improved. At this time, since the amount of scooping of each cylindrical body 22 is made substantially uniform, the amount entering each sandbag F becomes substantially constant, and the quality of the sandbag does not vary. Moreover, since the main body 20 fills the plurality of sandbag bags F at the same time, the manufacturing efficiency of the sandbag can be improved.
After that, the opening 41 of the sandbag bag F is fastened with a fastening string using the hook 27, is removed from the stand 40, and the sandbag is completed.
