Description

本発明は、磁石付きパワーショベルに関し、廃棄物を掴む爪と、廃棄物に混入する磁性体を他と選別する磁石との機能のそれぞれが、有効に発揮されるようにすることが発明の目的である。   The present invention relates to a power shovel with a magnet, and it is an object of the present invention to make each of the functions of a claw that grips waste and a magnet that sorts magnetic materials mixed in waste with each other effective. It is.

従来、磁石付きのショベルとしては、図４（Ａ），（Ｂ）乃至図５に示すように、作業機（図示せず）のアーム２１の先端に、リンク２２を介して若しくは油圧シリンダー２３を介して、一対の把持用の爪２４，２５が設けられている。そして、前記爪２４には、爪２４の廃棄物を挟む把持面２４ａと磁石２６の吸着面とを同一面にして、磁石２６が固定して設けられている。   Conventionally, as a shovel with a magnet, as shown in FIGS. 4 (A), (B) to 5, a hydraulic cylinder 23 is attached to the tip of an arm 21 of a working machine (not shown) via a link 22 or. A pair of gripping claws 24 and 25 are provided. The claw 24 is provided with the magnet 26 fixed so that the gripping surface 24a sandwiching the waste of the claw 24 and the attracting surface of the magnet 26 are flush with each other.

また、図６に示すように、作業機におけるバケット２７の底壁の外側に、電磁石２８を固定して、廃棄物の押込み、破砕及び大小の選別と鉄くずの吸着回収が出来るようにしたものが知られている（特許文献１参照）。
特開２００７−１４６７０号公報 In addition, as shown in FIG. 6, an electromagnet 28 is fixed to the outside of the bottom wall of the bucket 27 in the work machine, so that waste can be pushed in, crushed and sorted in size, and scrap iron can be adsorbed and recovered. Is known (see Patent Document 1).
JP 2007-14670 A

しかし、従来の磁石付きパワーショベルやバケットにおいては、前記磁石がショベルに固定して設けられていて、爪の把持作用を邪魔しないように取り付けられる。また、爪は、前記磁石による板類などの吸着作用を邪魔しないように、磁石の吸着面から突出しないように設置されるので、結局、その爪の把持面と磁石の吸着面とを面一にせざるを得ない。その結果、従来のパワーショベルでは、沢山の廃棄物を掴むことができずにいる。本発明に係る磁石付きパワーショベルは、このような課題を解決するために提案されたものである。   However, in conventional power shovels and buckets with magnets, the magnets are fixed to the shovel and attached so as not to interfere with the gripping action of the claws. Further, since the claw is installed so as not to protrude from the magnet adsorption surface so as not to disturb the adsorption action of the magnets and the like by the magnet, the claw gripping surface and the magnet adsorption surface are eventually flush with each other. I have to make it. As a result, a conventional power shovel cannot grasp a lot of waste. The power shovel with a magnet according to the present invention has been proposed in order to solve such a problem.

本発明に係る磁石付きパワーショベルの上記課題を解決して目的を達成するための要旨は、パワーショベルに磁石が取り付けられて、破棄物を把持してその廃棄物中の磁性体を選別する磁石付きパワーショベルにおいて、前記パワーショベルを構成する一対の回動自在な爪のうち、一方の爪に磁石を設けると共に、当該一方の爪の把持面から外に向けて前記磁石の吸着面が突出するように移動突出手段が設けられて、前記磁石が前記一方の爪の把持面から出没自在にされていることである。   The gist for solving the above-mentioned problems of the power shovel with magnets according to the present invention is that a magnet is attached to the power shovel, holds the waste, and sorts out the magnetic material in the waste. In the attached power shovel, a magnet is provided on one of the pair of rotatable claws constituting the power shovel, and the attracting surface of the magnet protrudes outward from the gripping surface of the one claw. As described above, the moving projecting means is provided so that the magnet can protrude and retract from the holding surface of the one claw.

また、本発明に係る磁石付きパワーショベルの上記改題を解決して目的を達成する要旨は、パワーショベルに磁石が取り付けられて、破棄物を把持してその廃棄物中の磁性体を選別する磁石付きパワーショベルにおいて、前記パワーショベルを構成する一対の回動自在な爪のうち、一方の爪の背面側に揺動アームを介して磁石を設けると共に、前記揺動アームを駆動させるアーム駆動装置が設けられ、前記磁石は前記一対の爪の作業範囲外にて吸着作業が可能になっていることである。   Further, the gist of achieving the object by solving the above-mentioned modification of the power shovel with magnets according to the present invention is that a magnet is attached to the power shovel, holds the waste, and selects the magnetic material in the waste. In the attached power shovel, an arm driving device for providing a magnet via a swing arm on the back side of one of the pair of rotatable claws constituting the power shovel and driving the swing arm is provided. It is provided that the magnet is capable of being attracted outside the working range of the pair of claws.

本発明の磁石付きパワーショベルによれば、このような磁石付きパワーショベルであれば、ショベルで多くの廃棄物等をしっかり掴むことができるようになり、一方で、磁石をショベルの爪よりも突出させて使用すれば、爪が邪魔にならず、地面に置かれた板等の平板体も容易に吸着することができる。こうして、廃棄物を掴むことと、磁性体を選別することという両作業が、能率良く行えるものである。   According to the power shovel with magnets of the present invention, with such a power shovel with magnets, it becomes possible to firmly hold a large amount of waste etc. with the shovel, while the magnet protrudes more than the claw of the shovel. If used, the claws do not get in the way, and a flat plate such as a plate placed on the ground can be easily adsorbed. Thus, both the work of grasping the waste and the selection of the magnetic material can be performed efficiently.

本発明に係る磁石付きパワーショベル１について、図１乃至図２を参照して説明する。なお、従来例に対応する部分には従来例と同一符号を付けて説明する。クローラなどで移動自在な作業機におけるパワーショベルに磁石が取り付けられて、破棄物を把持してその廃棄物中の磁性体を選別する磁石付きパワーショベル１において、前記パワーショベル１を構成する一対の回動自在な爪２４，２５のうち、一方の爪２４に磁石２６を設けると共に、当該一方の爪２４の把持面２４ａから外に向けて前記磁石２６の吸着面２６ａが突出するように移動突出手段７が設けられて、前記磁石２６が前記一方の爪２４の把持面２４ａから外へ出没自在にされている。   A power shovel 1 with a magnet according to the present invention will be described with reference to FIGS. Note that portions corresponding to the conventional example are denoted by the same reference numerals as those of the conventional example. In a power shovel 1 with a magnet that attaches a magnet to a power shovel in a work machine that is movable by a crawler or the like and grips a waste material and selects a magnetic material in the waste material, a pair of power shovels 1 constituting the power shovel 1 A magnet 26 is provided on one claw 24 of the freely movable claws 24 and 25, and the magnet 26 is moved so that the attracting surface 26a projects outward from the gripping surface 24a of the one claw 24. Means 7 are provided so that the magnet 26 can freely move in and out from the gripping surface 24 a of the one claw 24.

前記磁石２６は、永久磁石若しくは電磁石である。そして、前記移動突出手段７は、例えば、油圧シリンダーであり、前記一方の爪２４の背部に回動自在な油圧シリンダー用の支点部７ａが設けられて、そこに油圧シリンダー７の一端部が回動自在に連結されている。   The magnet 26 is a permanent magnet or an electromagnet. The moving projecting means 7 is, for example, a hydraulic cylinder, and a fulcrum portion 7a for a rotatable hydraulic cylinder is provided on the back of the one claw 24, and one end of the hydraulic cylinder 7 is rotated there. It is connected freely.

前記油圧シリンダー７のロッド先端部７ｂは、磁石２６の上部支点部に回転自在に連結されている。また、前記磁石２６の一端側の基部２６ｂが、前記一方の爪２４の基部近傍に回転自在にして連結されている。   The rod tip 7b of the hydraulic cylinder 7 is rotatably connected to the upper fulcrum of the magnet 26. Further, a base portion 26 b on one end side of the magnet 26 is rotatably connected to the vicinity of the base portion of the one claw 24.

また、他方の爪２５は、図１乃至図２に示すように、支点部２５ａでアーム２１に回動自在に連結されており、作用部２５ｂに油圧シリンダー２３のロッド先端部が回転自在にして連結されている。この爪２５と、アーム２１の先端に基部２４ｂが回動自在に連結されている前記爪２４とで、廃棄物等を挟持して掴むものである。   Further, as shown in FIGS. 1 and 2, the other claw 25 is rotatably connected to the arm 21 by a fulcrum portion 25a, and the rod end portion of the hydraulic cylinder 23 is rotatable to the action portion 25b. It is connected. The claw 25 and the claw 24 having the base 24b rotatably connected to the tip of the arm 21 sandwich and hold the waste or the like.

以上のような構成により、前記磁石付きパワーショベル１は、前記油圧シリンダー７を駆動させて、磁石２６を引き込んで後退させておけば、一対の爪２４，２５とが廃棄物等を掴むことができる。また、鉄板等の平板体を磁石２６で吸着するときには、図２に示すように、油圧シリンダー２３でロッドを引き込み、爪２５を後退させ、また、リンク２２で爪２４を引き込んで後退させる。   With the configuration as described above, if the excavator 1 with magnet drives the hydraulic cylinder 7 and retracts the magnet 26 by retracting it, the pair of claws 24 and 25 can grasp waste and the like. it can. Further, when attracting a flat plate such as an iron plate with the magnet 26, as shown in FIG. 2, the rod is retracted by the hydraulic cylinder 23, the claw 25 is retracted, and the claw 24 is retracted by the link 22.

次に、油圧シリンダー７を駆動させてそのロッドを伸長させると、一端側の基部２６ｂを中心にして磁石２６が回転する。その磁石２６の吸着面２６ａが、爪２４の把持面２４ａよりも突出する。こうして、アーム２１を下げるようにすれば、この磁石２６によって、地面の上に敷いてある鉄板等の磁性体を確実に吸着することができる。   Next, when the hydraulic cylinder 7 is driven to extend the rod, the magnet 26 rotates around the base portion 26b on one end side. The attracting surface 26 a of the magnet 26 protrudes from the gripping surface 24 a of the claw 24. Thus, if the arm 21 is lowered, the magnet 26 can reliably attract a magnetic material such as an iron plate laid on the ground.

本発明に係る第２実施例の磁石付きパワーショベル２は、図３（Ａ），（Ｂ）に示すように、前記パワーショベル１を構成する一対の回動自在な爪２４，２５のうち、一方の爪２４の背面側に平行リンク的に設けた揺動アーム３（３ａ，３ｂ）を介して磁石２６を揺動自在に設けると共に、前記揺動アーム３を駆動させ揺動させるアーム駆動装置（図示せず）が設けられている。   As shown in FIGS. 3 (A) and 3 (B), the power shovel 2 with a magnet according to the second embodiment of the present invention includes a pair of rotatable claws 24 and 25 constituting the power shovel 1. An arm drive device that swingably provides a magnet 26 via a swing arm 3 (3a, 3b) provided in parallel links on the back side of one claw 24 and drives the swing arm 3 to swing. (Not shown) is provided.

前記一対の爪２４，２５は、図３（Ａ）に示すように、支点部４ａを中心にして回動するレバー４によってこれと一体的にして爪２４が開閉され、これらと同時に、前記レバー４に連結されるリンクバー５によって爪２５が支点部２５ｃを中心にして開閉される。そして、前記レバー４は、油圧シリンダー６によって回転駆動されるものである。   As shown in FIG. 3A, the pair of claws 24 and 25 are integrally opened and closed by a lever 4 that rotates about a fulcrum portion 4a, and at the same time, the lever The claw 25 is opened and closed around the fulcrum portion 25c by the link bar 5 connected to 4. The lever 4 is rotationally driven by a hydraulic cylinder 6.

前記磁石２６を使用するときには、図３（Ｂ）に示すように、油圧シリンダー６のロッドを伸長させて、前記レバー４とリンクバー５とにより一対の爪２４，２５を閉じた状態にして、次に、前記アーム駆動装置で揺動アーム３を下方に向かって回動させる。この揺動アーム３の回動により、磁石２６が爪２４，２５の下位置に配置される。磁石２６の吸着面２６ａが略水平状態になったところで、地面の鉄板等の磁性体を前記磁石２６で吸着するものである。   When using the magnet 26, as shown in FIG. 3B, the rod of the hydraulic cylinder 6 is extended, and the pair of claws 24 and 25 are closed by the lever 4 and the link bar 5, Next, the swing arm 3 is rotated downward by the arm driving device. As the swing arm 3 is rotated, the magnet 26 is disposed below the claws 24 and 25. When the attracting surface 26a of the magnet 26 is in a substantially horizontal state, a magnetic body such as an iron plate on the ground is attracted by the magnet 26.

このようにして、第２実施例に係る磁石付きパワーショベル２によれば、前記一対の爪２４，２５の作業範囲外にて吸着作業が可能になって、爪２４，２５に邪魔されず磁気選別作業が容易となり、作業効率が向上するものである。   Thus, according to the power shovel 2 with a magnet according to the second embodiment, it is possible to perform an adsorption work outside the working range of the pair of claws 24, 25, and the magnets are not disturbed by the claws 24, 25. Sorting work is facilitated and work efficiency is improved.
