造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an airframe with a boom that can freely swing up and down, an arm with a bucket at its tip that is installed on the boom so that it can swing back and forth, and the boom a proximal boom member attached to the base end boom member so as to be swingable up and down, an intermediate boom member attached to the base end boom member so as to be swingable left and right, and a boom member attached to the intermediate boom member so as to be swingable in the left and right directions. A movably attached distal end boom member for arm connection is provided, a hydraulic cylinder is provided across the proximal end boom member and the intermediate boom member to relatively swing them left and right, and the distal end boom member is moved in parallel. The present invention relates to a boom structure of a backhoe, in which a link is provided across the proximal end side poom member and the distal end side boom member in parallel with the intermediate boom member.
従来の上記ブーム構造では、先端側ブーム部材が常時平
行移動するように、リンクを基端側ブーム部材と先端側
ブーム部材とに取付けてあった（例えば実開昭６０−８
７４０号公報）。In the conventional boom structure described above, a link is attached to the proximal boom member and the distal boom member so that the distal boom member always moves in parallel (for example, in
Publication No. 740).
しかし、先端側ブーム部材を平行移動させて掘削する場
合には、例えば第２図に示すように、機体の横側近くの
溝（２３）を、その横倒に沿って平行に掘削することが
できるけれども、機体から離れた溝を平行に掘ることが
できないという欠点があった。However, when excavating by moving the distal end boom member in parallel, it is possible to excavate the groove (23) near the side of the fuselage in parallel along the sideways tilt, as shown in Fig. 2, for example. Although it was possible, the drawback was that it was not possible to dig parallel trenches away from the aircraft.
本発明の目的は、機体の横側近くの溝だけでなく、機体
から離れた溝をも掘削できるようにする点にある。An object of the present invention is to enable excavation of not only trenches near the sides of the fuselage, but also trenches remote from the fuselage.
本発明におけるバックホウのブーム構造の特徴構成は、
基端側ブーム部材に対してリンクを着脱自在に取付け、
前記リンクを前記基端側ブーム部材から取外した状態で
中間ブーム部材と先端側ブーム部材とを相対揺動不能に
する固定手段を設けてあることにあり、その作用効果は
、次の通りである。The characteristic configuration of the backhoe boom structure in the present invention is as follows:
Attach the link removably to the proximal boom member,
The fixing means is provided to prevent the intermediate boom member and the distal boom member from relative swinging when the link is removed from the proximal boom member, and its effects are as follows. .
つまり、リンクを基端側ブーム部分に取付けて、中間ブ
ーム部材と先端側ブーム部材とを相対揺動自在にしたま
ま、油圧シリンダを伸縮操作すれば、先端側ブーム部材
が平行移動して機体の横側近くの溝を掘削でき、また、

にして、油圧シリンダを伸縮操作すれば、先端側ブーム
部材は中間ブーム部材と一体に、基端側ブーム部材に対
して左右に揺動し、機体から離れた溝を掘削できる。In other words, if the link is attached to the proximal boom part and the intermediate boom member and the distal boom member are allowed to swing relative to each other and the hydraulic cylinder is extended or retracted, the distal boom member will move in parallel and the fuselage will move. You can dig trenches near the sides, and
If the link is removed from the proximal boom member, the intermediate boom member and the distal boom member are rendered immovable relative to each other by the fixing means, and the hydraulic cylinder is extended and retracted, the distal boom member becomes integral with the intermediate boom member. It swings left and right with respect to the proximal boom member and can excavate trenches that are far from the machine body.
従って、簡単な改造で工事現場にあった溝を掘削でき、
作業性を向上させることができた。Therefore, with simple modifications, you can dig a trench that matches the construction site.
We were able to improve work efficiency.
次に、本発明の実施例を、図面に基づいて説明する。 Next, embodiments of the present invention will be described based on the drawings.
