Description
【考案の詳細な説明】 本考案は、バックホーの取付装置に関する。[Detailed explanation of the idea] The present invention relates to a mounting device for a backhoe.
後輪を有するトラクタ車体の後部には、該トラクタが牽
引動力車であることから、各種の作業機が取付けられる
。Since the tractor is a traction motor vehicle, various working machines are attached to the rear part of the tractor body having rear wheels.
即ち、三点リンク機構を介して耕耘機、モー７等の農作
業機を昇降自在に連結したり、又、作業部が本体に対し
て昇降自在とされたショベル系掘削機であるバックホー
を連結したりしている。In other words, it is possible to connect agricultural machinery such as a power tiller or Mo-7 through a three-point linkage mechanism so that it can be raised and lowered, or to connect a backhoe, which is a shovel-type excavator whose working part can be raised and lowered relative to the main body. I'm doing it.
ところで、三点リンク機構を介してバックホーを連結す
ると、該バックホーがトラクタ車体より大きく突出し、
バックホーによる作業が比較的重作業を伴うものである
から、作業の安定性に欠けるし、又、路上走行も不利で
ある。By the way, when a backhoe is connected via a three-point linkage mechanism, the backhoe protrudes far beyond the tractor body.
Since work with a backhoe involves relatively heavy work, it lacks work stability and is also disadvantageous for running on the road.
しかして、バックホーをトラクタ車体に連結するとすれ
ば、その構造的特異性から複雑な取付台を設ける必要が
あり、三点リンク機構を介して連結する作業機の連結に
支障が生じる。However, if the backhoe is to be connected to the tractor body, it is necessary to provide a complicated mounting base due to its unique structure, which poses a problem in connecting the work implement via the three-point linkage mechanism.
そこで、本考案は後輪を有するトラクタ車体の後部に三

トラクタ車体に最適位置に連結して取付は可能でありな
がら、三点リンク機構による他の作業機、例えば耕耘機
、モー７等の連結にも支障なきようにしたものである。Therefore, in the present invention, a three-point linkage mechanism is attached to the rear of a tractor body having rear wheels by fixing a stand, while a backhoe has a working part at the rear of the main body and a forward-protruding connecting frame at the front of the main body. , the above-mentioned mounting is such that the three-point link mechanism and the front side of the connecting frame are selectively attachable and detachable to the base, and the connecting frame is attached so that when connected to the base, the main body of the backhoe is located behind the rear wheels. By developing a mounting device for a backhoe that is characterized by having a longitudinal length of It is designed so that there is no problem in connecting the power tiller, Mo-7, etc.
以下、図面を参照して本考案の実施例を詳述する。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

ている。That is, as for the backhoe 2, by sequentially connecting the first fixed frame 20 and the second fixed frame 21 to the fixed frame mounting bracket 16, the backhoe main body 22 having a working part, for example, a packet, is attached to the rear part. Specifically, the first fixed frame 20 has a first fixed frame main body 23 that is wider than the common mounting board 9, and a first fixed frame main body 23 that fits on both sides of each fixed frame mounting bracket 16 on the front surface of the main body 23. In addition, there is a first mounting bracket 24 which is removably connected by a pin connection through correspondingly arranged upper and lower pin holes 17 and 17, and a first mounting bracket 24 which is vertically installed at wide intervals on the rear side of the main body 23 and which is attached to its upper end. The bottle hole 17 is also welded through the bottle hole 17 and the second attachment bracket 26 is provided with a welded attachment rod 25 at the lower end to form one connection frame, which protrudes forward from the backhoe main body 22. , front first mounting bracket 24
A notch 27 is formed at a location corresponding to the lower link pivot shaft 18 so that it can be assembled while avoiding contact with the lower link pivot shaft 18.

ク機構３が構成される。Furthermore, the backhoe 2 described above was removed and a new lifting link mechanism 3 for the tilling device was installed as shown in FIGS. 2 and 3. At this time, a top link mounting bracket 10 and a fixed frame mounting bracket 16 were also installed. The common mounting board 9 will remain attached, and the top link mounting bracket)
A top link 44 or an auxiliary underframe (not shown) for attaching the top link is connected to the lower link 45 via the lower link pivot shaft 18 of the fixed frame mounting bracket 16.
A three-point elevating link mechanism 3 is constructed by connecting a check chain 46 attached thereto and further adding a lift rod 47.
従って上記構成ではバックホー２が進退できるので、１

~ With the tractor in place and moving it backwards for a long time, excavating a certain length, then raising the outrigger 42 and bringing the backhoe 2 closer to the position, the trench length can be further increased by the amount of forward and backward stroke. Therefore, it is possible to excavate for a long time without moving the tractor.

性が向上すると共に掘削自体も能率的かつ的確になる。In addition, if the backhoe 2 is intentionally moved to the rear, the outrigger 42 will accompany the excavator, which will lengthen the ground contact interval and improve the overall stability of the tractor.If you excavate in this position, the front of the tractor will be less likely to climb up. Operators can perform operations smoothly and accurately, improving safety especially when working on slopes, and the excavation itself becomes efficient and accurate.
更にバックホー２をトラクタに接近させて走行すると全
体の安定性がよくなり走行に伴なう振動も少なく転倒の
危険もなくなると共に車両旋回時の安全性が向上する。Furthermore, when the backhoe 2 runs close to the tractor, the overall stability is improved, vibrations accompanying the running are reduced, there is no danger of overturning, and the safety when the vehicle turns is improved.

付装置に係るものであるから、次のような利点がある。In the present invention, a stand is fixed to the rear of a tractor body having rear wheels to attach a three-point linkage mechanism, while a backhoe has a working section at the rear of its main body, a forward-protruding connecting frame at the front of its main body, and The three-point link mechanism and the front side of the connecting frame are selectively attached to and detachable from the base, and the connecting frame is attached to the front and back where the backhoe body is located behind the rear wheel when connected to the base. Since the present invention relates to a backhoe attachment device characterized by a long length, it has the following advantages.

が択一的に着脱自在にされているので、取付は台を三点
リンク機構用の作業機にもバックホーにも利用でき構造
は簡単でコストダウンを図れるので゛ある。The mounting is fixed to the rear of the tractor body, and the three-point linkage mechanism and the connecting frame protruding forward from the backhoe body are selectively removable. It can be used for both mechanical work machines and backhoes, and the structure is simple and costs can be reduced.
また、連結枠はこれを取付は台に連結したときの前後長
