Description

本発明は、様々な大きさの土砂や夾雑物をバケット本体にすくいながら、大きさに応じて土砂や夾雑物をバケット本体で篩い分けすることのできるスケルトンバケットに関する。   The present invention relates to a skeleton bucket capable of sieving earth and sand and foreign substances with a bucket body according to the size while scooping various sizes of earth and sand and foreign substances into the bucket body.

様々な大きさの土砂や夾雑物（根茎、岩石又はコンクリートブロック等）をバケット本体にすくいながら、大きさに応じて土砂や夾雑物をバケット本体で篩い分けすることのできるスケルトンバケットは、例えば特許文献１に見られるように、バケット本体の底板や側板に多数の開孔を設けた構成が知られている。こうしたスケルトンバケットは、様々な大きさの土砂や夾雑物をバケット本体にすくいながら、前記バケット本体を小刻みに揺すって、大きさが開孔以下の土砂や夾雑物を底板や側板の開孔から落下させ、バケット本体に開孔より大きな土砂や夾雑物のみを残すことにより、大きさに応じて土砂や夾雑物を篩い分けする。   Skeleton buckets that can screen soil and sand according to their size while scooping various sizes of sand and dirt (rhizome, rocks, concrete blocks, etc.) into the bucket body are, for example, patents As can be seen in Document 1, a configuration in which a large number of holes are provided in a bottom plate and a side plate of a bucket body is known. Such skeleton buckets are used to scoop soil and sand of various sizes into the bucket body, rocking the bucket body in small increments, and dropping soil and dirt that is less than or equal to the size of the opening from the openings in the bottom and side plates. By leaving only the earth and sand larger than the opening in the bucket body, the earth and sand are sieved according to the size.

特開2007-224539号公報JP 2007-224539

特許文献１が開示するスケルトンバケットは、開孔がすべて円孔である。しかし、円孔である開孔は、開孔間に残る梁の幅が細くなったり、太くなったりするため、相対的に細い幅の梁に応力が集中し、開孔を設けたバケット本体の底板又は側板が変形する可能性がある。これは、スケルトンバケットを利用して、バケット本体の底板で掘削場所を押さえつける簡易の転圧（展圧とも言う。）や均し作業をした場合、バケット本体の底板を変形させ、最悪破損させる可能性があるという形で問題となる。そこで、こうした細い梁に応力が集中せずに、簡易な転圧や均し作業に利用することのできるスケルトンバケットを開発するべく、検討した。   As for the skeleton bucket which patent document 1 discloses, all the openings are circular holes. However, since the width of the beam remaining between the apertures becomes narrower or thicker, the stress is concentrated on the relatively narrow beam, and the opening of the bucket body provided with the aperture is a circular hole. The bottom plate or the side plate may be deformed. This is because the bottom plate of the bucket body can be deformed and damaged in the worst case when a simple rolling pressure (also called expansion pressure) or leveling work is performed using the skeleton bucket to hold the excavation site with the bottom plate of the bucket body. It becomes a problem in the form of sexuality. Therefore, we studied to develop a skeleton bucket that can be used for simple rolling and leveling without stress concentration on these thin beams.

検討の結果開発したものが、様々な大きさの土砂や夾雑物をバケット本体にすくいながら、大きさに応じて土砂や夾雑物をバケット本体で篩い分けすることのできるスケルトンバケットにおいて、バケット本体は、底板に複数の六角形の開孔を同じ向きに揃えて前記開孔間の梁が同幅となるように並べたスケルトンバケットである。六角形の開孔は、それぞれの角を前後方向に揃えて並べる、又はそれぞれの角を左右方向に揃えて並べるとよい。ここに言う「前後方向」は、建設機械のアーム及びブームの屈曲方向を、また「左右方向」は前記屈曲方向に直交する方向を意味する。このほか、六角形の開孔の大きさや個数、底板や側板の厚みは、底板に要求される剛性や土砂や夾雑物の篩い分けの程度等を勘案し、適宜決定する。   The skeleton bucket that was developed as a result of the study was a skeleton bucket that could screen soil and sand according to the size while scooping various sizes of earth and sand and impurities into the bucket body. A skeleton bucket in which a plurality of hexagonal apertures are aligned in the same direction on the bottom plate so that the beams between the apertures have the same width. The hexagonal holes may be arranged with their respective corners aligned in the front-rear direction, or with the respective corners aligned in the left-right direction. The “front-rear direction” mentioned here means the bending direction of the arm and boom of the construction machine, and the “left-right direction” means the direction orthogonal to the bending direction. In addition, the size and number of hexagonal holes and the thickness of the bottom plate and the side plate are appropriately determined in consideration of the rigidity required for the bottom plate, the degree of sieving of earth and sand, and foreign substances.

本発明のスケルトンバケットは、バケット本体の底板に六角形の開孔を並べ、開孔間に形成される梁を同幅にしている。これにより、スケルトンバケットを転圧や均し作業に利用する際、特定の梁に応力集中させることなく、バケット本体の底板の変形を防止できる。また、同幅の梁で済むことは、円孔の開孔を並べた同種スケルトンバケットに比べて重量軽減に寄与するから、本発明のスケルトンバケットは軽量化され、それだけ建設機械がスケルトンバケットを動かすための燃料が節約され、排気ガスを低減できる。   In the skeleton bucket of the present invention, hexagonal openings are arranged on the bottom plate of the bucket body, and beams formed between the openings have the same width. Thereby, when using a skeleton bucket for rolling and leveling work, it is possible to prevent deformation of the bottom plate of the bucket body without concentrating stress on a specific beam. In addition, the fact that the beam of the same width is sufficient contributes to weight reduction compared to the same kind of skeleton bucket in which circular holes are arranged, so that the skeleton bucket of the present invention is reduced in weight and the construction machine moves the skeleton bucket by that amount. This saves fuel and reduces exhaust gas.

ここで、バケット本体は、前後方向に湾曲した底板に複数の六角形の開孔を同じ向きに揃えて並べた構成にしたり、更に前記前後方向に湾曲した底板の湾曲形状に倣った湾曲縁を前記底板の左右側縁部それぞれに直交して左右一対の側板を突き当てる構成にすると、バケット本体の底板の剛性が高くなり、スケルトンバケットを転圧や均し作業に利用する際にバケット本体の底板の変形を防止できる。この場合、バケット本体の側板に開孔を設けないことで、前記側板を突き当てる底板の剛性を向上させている。   Here, the bucket body has a configuration in which a plurality of hexagonal openings are aligned in the same direction on a bottom plate curved in the front-rear direction, or a curved edge following the curved shape of the bottom plate curved in the front-rear direction. When configured to abut against a pair of left and right side plates orthogonal to the left and right side edge portions of the bottom plate, the rigidity of the bottom plate of the bucket body increases, and when the skeleton bucket is used for rolling and leveling work, Deformation of the bottom plate can be prevented. In this case, the rigidity of the bottom plate against which the side plate is abutted is improved by not providing a hole in the side plate of the bucket body.

ここで、底板に並べられた開孔は六角形であるため、側縁部に沿って並ぶ左右両側の開孔の前記側縁部に最も近い周縁を仮想的に結ぶとジグザグに蛇行する。これは、各開孔の周縁と側縁部との距離が変化し、前記距離の短い部分で応力集中が起きる可能性があることを意味する。これから、バケット本体は、底板の側縁部に沿って並ぶ複数の開孔を、前記側縁部に平行かつ一直線状に延びる区画周縁で区切った変形多角形にするとよい。ここで、「変形多角形」とは正多角形の対義語として、ある向きで左右非対称となる多角形を意味する。   Here, since the openings arranged in the bottom plate are hexagonal, when the peripheral edges closest to the side edge portions of the left and right openings arranged along the side edge portion are virtually connected, the zigzag meanders. This means that the distance between the peripheral edge and the side edge of each aperture varies, and stress concentration may occur at the short distance. From this, it is preferable that the bucket body has a deformed polygon in which a plurality of apertures arranged along the side edge of the bottom plate are partitioned by a partition peripheral edge extending in a straight line parallel to the side edge. Here, the “deformed polygon” means a polygon that is asymmetric in a certain direction as a synonym of a regular polygon.

また、上述のように、各開孔の周縁と前記底板の前縁部又は後縁部との距離が変化すると、前記距離の短い部分で応力集中が起きる可能性がある。そこで、バケット本体は、底板の前縁部又は後縁部に沿って並ぶ複数の開孔を、前記前縁部又は後縁部に平行かつ一直線状に延びる区画周縁で区切った変形多角形にするとよい。ここにいう「変形多角形」も上述と同義であるが、側縁部、前縁部又は後縁部に沿って並ぶ開孔のいずれもが同じ形状であることを意味しない。   In addition, as described above, when the distance between the peripheral edge of each aperture and the front edge portion or the rear edge portion of the bottom plate changes, stress concentration may occur in a portion where the distance is short. Therefore, when the bucket body is formed into a deformed polygon in which a plurality of apertures arranged along the front edge portion or the rear edge portion of the bottom plate are separated by a partition edge extending in a straight line parallel to the front edge portion or the rear edge portion. Good. The “deformed polygon” here has the same meaning as described above, but does not mean that all of the openings arranged along the side edge, the front edge, or the rear edge have the same shape.

本発明のスケルトンバケットは、応力の集中する梁を形成することなく、また底板全体の剛性を高めているため、簡易な転圧や均し作業に利用してもバケット本体の底板を変形させることがなく、従来同種のスケルトンバケットに比べて利用範囲を拡充することができる。これは、バケット本体の底板に並べる開孔を六角形とし、開孔間に形成される梁を同幅にしたこと、また前記底板を湾曲させてバケット本体を構成したり、更に側板を前記底板に対して突き当てて組み付けてバケット本体を構成したことにより、バケット本体の底板の剛性が高められたことによる効果である。更に、底板の側縁部、前縁部又は後縁部に平行な区画周縁で区切られた変形多角形の開孔を形成すれば、側縁部、前縁部又は後縁部における剛性の低下がなくなり、全体にわたってバケット本体の底板の剛性を高めることができる。   Since the skeleton bucket of the present invention does not form a stress-concentrating beam and increases the rigidity of the entire bottom plate, the bottom plate of the bucket body can be deformed even when used for simple rolling and leveling operations. Therefore, the range of use can be expanded compared to the conventional skeleton bucket of the same type. This is because the holes arranged on the bottom plate of the bucket body are hexagonal, the beams formed between the openings are made the same width, the bottom plate is curved to form the bucket body, and the side plate is further connected to the bottom plate. This is the effect of increasing the rigidity of the bottom plate of the bucket body by constructing the bucket body by abutting against and assembling. Further, if a deformed polygonal aperture is formed that is partitioned by a partition peripheral edge parallel to the side edge, front edge, or rear edge of the bottom plate, the rigidity of the side edge, front edge, or rear edge decreases. The rigidity of the bottom plate of the bucket body can be enhanced throughout.

The right side view of this example is omitted because it appears in the same way as the left side view. Further, the left side view and the right side view of the other example appear in the same manner as the left side view of the present example, and thus are omitted.

本例のスケルトンバケット１は、図１に見られるように、バケット本体11の底板12の後縁部から連続したブラケット取付板161に、取付補助板162と共に連結ブラケット16が取り付けられ、前記連結ブラケット16に建設機械のアーム３の先端と、前記アーム３に取り付けられたバケットシリンダ（図示略）のロッド32又は前記ロッド32から延長された連結リンク31とを連結して、アーム３に対して前後方向に首振りするように動作される。これにより、様々な大きさの土砂や夾雑物をバケット本体11にすくいながら、バケット本体11の首振り運動やアームの屈曲運動等を利用して、大きさに応じて土砂や夾雑物をバケット本体11で篩い分けする。こうした篩い分け機能は、従来同種のスケルトンバケットと代わりがない。   In the skeleton bucket 1 of this example, as shown in FIG. 1, a connecting bracket 16 is attached to a bracket mounting plate 161 that is continuous from the rear edge of the bottom plate 12 of the bucket body 11 together with a mounting auxiliary plate 162. The front end of the arm 3 of the construction machine is connected to the rod 32 of the bucket cylinder (not shown) attached to the arm 3 or the connection link 31 extended from the rod 32 to the front and rear. Operated to swing in the direction. As a result, while scooping various sizes of sand and dirt into the bucket body 11, the bucket body 11 can be moved according to the size by using the swing motion of the bucket body 11 or the arm bending motion. Sift with 11. Such a sieving function has no substitute for the conventional skeleton bucket.

本例のバケット本体11は、図２〜図６に見られるように、首振りする前後方向に湾曲した底板12と、底板12の湾曲形状に倣った湾曲縁151を前記底板12の左右側縁部121,121それぞれに直交して組み付けた左右一対の側板15とから構成される。また、本例のスケルトンバケット１は、側板15に開孔を設けていない。底板12の前縁部122には、厚みのある板材から構成される爪取付板171が取付られ、前記爪取付板171に掘削用の爪17が取り付けられている。また、同じく底板12の後縁部123にはブラケット取付板161を接続した上で、前記ブラケット取付板161に取付補助板162と共に連結ブラケット16が取り付けられている。ブラケット取付板161は、連結ブラケット16の取付代を稼ぐ目的がある。   2 to 6, the bucket body 11 of the present example includes a bottom plate 12 curved in the front-rear direction for swinging, and curved edges 151 following the curved shape of the bottom plate 12, on the left and right side edges of the bottom plate 12. It comprises a pair of left and right side plates 15 assembled orthogonally to each of the parts 121 and 121. Further, the skeleton bucket 1 of this example does not have an opening in the side plate 15. A claw attachment plate 171 made of a thick plate material is attached to the front edge portion 122 of the bottom plate 12, and a claw 17 for excavation is attached to the claw attachment plate 171. Similarly, a bracket mounting plate 161 is connected to the rear edge 123 of the bottom plate 12, and a connecting bracket 16 is attached to the bracket mounting plate 161 together with an auxiliary mounting plate 162. The bracket mounting plate 161 has the purpose of increasing the mounting cost of the connecting bracket 16.

底板12は、複数の正六角形の開孔13の各角を前後方向に揃えて並べている。側縁部121に沿って並ぶ開孔19は、側縁部121に平行な区画周縁191で区切られた変形多角形である。区画周縁191は、元の周縁とほぼ変らない位置に前記元の周縁と同じく側縁部121に沿って延びているため、各図中に図示される開孔18は基本的な開孔13と外観上ほとんど変らない。また、前縁部122又は後縁部123に沿って並ぶ開孔18は、平行な区画周縁181で区切られた変形多角形である。区画周縁181は、左右対称に斜めに延びる周縁を胯ぐように設けられるため、各図中に図示される開孔18は基本的な開孔13の角を切り欠いた変形七角形に見える。   The bottom plate 12 is arranged with the corners of the plurality of regular hexagonal apertures 13 aligned in the front-rear direction. The openings 19 arranged along the side edge 121 are deformed polygons delimited by partitioning peripheral edges 191 parallel to the side edge 121. Since the partition peripheral edge 191 extends along the side edge 121 in the same manner as the original peripheral edge at a position substantially unchanged from the original peripheral edge, the opening 18 illustrated in each drawing is the basic opening 13. Almost no change in appearance. In addition, the apertures 18 arranged along the front edge portion 122 or the rear edge portion 123 are deformed polygons separated by parallel partition edges 181. Since the partition peripheral edge 181 is provided so as to line up the peripheral edge extending obliquely symmetrically, the opening 18 shown in each figure looks like a modified heptagon with the corners of the basic opening 13 cut out.

開孔13は、各角を前後方向に揃えて並んでおり、開孔13,13間の梁14を同幅にしている。正六角形の開孔13の大きさや個数、底板12や側板15の厚みは、底板12に要求される剛性や土砂や夾雑物の篩い分けの程度等を勘案し、適宜決定すればよいが、これらの仕様が変っても、梁14が同幅であれば、梁14に加わる負荷は等しくなる。これにより、本例のスケルトンバケット１を利用して、転圧や均し作業をする場合、底板12全体に荷重が均等に分散するため、梁14を中心とした底板12の変形や破損が防止できる。   The openings 13 are arranged with their corners aligned in the front-rear direction, and the beams 14 between the openings 13 and 13 have the same width. The size and number of regular hexagonal apertures 13 and the thickness of the bottom plate 12 and the side plate 15 may be appropriately determined in consideration of the rigidity required for the bottom plate 12, the degree of sieving of earth and sand, and foreign matters. If the beam 14 has the same width, the load applied to the beam 14 will be equal even if the specifications are changed. As a result, when rolling or leveling work is performed using the skeleton bucket 1 of this example, the load is evenly distributed throughout the bottom plate 12, so that deformation and breakage of the bottom plate 12 centered on the beam 14 are prevented. it can.

別例のスケルトンバケット２は、上記例示（図１〜図６参照）と外観及び構成はほぼ同じであり、ただ底板12に並べる開孔23の向きが各角を左右方向に揃えている点のみが異なる。すなわち、バケット本体21は、図７〜図10に見られるように、前後方向に湾曲した底板22と、湾曲縁251を前記底板22の左右側縁部221,221それぞれに直交して組み付けた左右一対の側板25とから構成される。また、別例のバケット本体21も、底板22の前縁部222に接続された爪取付板271に掘削用の爪27が取り付けられ、底板22の後縁部223に接続されたブラケット取付板261に取付補助板262と共に連結ブラケット26が取り付けられている。   The skeleton bucket 2 of another example is substantially the same in appearance and configuration as the above-described example (see FIGS. 1 to 6), and only the direction of the apertures 23 arranged in the bottom plate 12 aligns each corner in the left-right direction. Is different. That is, as seen in FIGS. 7 to 10, the bucket body 21 is composed of a pair of left and right bottom plates 22 that are curved in the front-rear direction, and a curved edge 251 that is assembled perpendicularly to the left and right side edges 221 and 221 of the bottom plate 22. It is composed of side plates 25. Further, in the bucket body 21 of another example, the claw 27 for excavation is attached to the claw attachment plate 271 connected to the front edge portion 222 of the bottom plate 22, and the bracket attachment plate 261 connected to the rear edge portion 223 of the bottom plate 22. The connecting bracket 26 is attached together with the auxiliary mounting plate 262.

複数の正六角形の開孔23は、各角が左右方向に揃えて底板22に並べられ、各開孔23,23間の梁24を同幅にしている。底板22全体の剛性は、梁24が同幅であることにより高められるので、開孔23の向きは関係ない。しかし、上記例示の開孔13から90度回転した開孔23であることから、側縁部221に沿って並ぶ開孔29や前縁部222又は後縁部223に沿って並ぶ開孔28は、上記例示の開孔19と開孔18とが入れ替わった関係になっている。すなわち、側縁部121に沿って並ぶ開孔29は、前後対称に斜めに延びる周縁を胯ぐ区画周縁291に区切られるるため、各図中に図示される開孔28は基本的な開孔23の角を切り欠いた変形七角形に見える。また、前縁部222又は後縁部223に沿って並ぶ開孔28は、側縁部121に平行な区画周縁181で区切られるため、基本的な開孔13と外観上ほとんど変らない。   The plurality of regular hexagonal openings 23 are arranged on the bottom plate 22 with their corners aligned in the left-right direction, and the beams 24 between the openings 23 and 23 have the same width. Since the rigidity of the entire bottom plate 22 is enhanced by the beam 24 having the same width, the direction of the opening 23 does not matter. However, since the opening 23 is rotated 90 degrees from the opening 13 illustrated above, the opening 29 aligned along the side edge 221 and the opening 28 aligned along the front edge 222 or the rear edge 223 are The opening 19 and the opening 18 in the above example are interchanged. That is, the apertures 29 arranged along the side edge portion 121 are divided into partitioning perimeters 291 that line the peripheries extending obliquely symmetrically in the front-rear direction, so that the apertures 28 illustrated in each drawing are the basic apertures. It looks like a deformed heptagon with 23 corners cut out. In addition, since the apertures 28 arranged along the front edge portion 222 or the rear edge portion 223 are separated by a partition peripheral edge 181 parallel to the side edge portion 121, the appearance is almost the same as that of the basic aperture 13.
