Description
【0001】[0001]
本考案はトラクタに装着する砕土装置の折り畳み時の固定構成に関する。 The present invention relates to a fixing structure for a crusher mounted on a tractor when the crusher is folded.
【0002】[0002]
トラクタの後部に装着した時、トラクタ機体幅より突出する幅広の砕土装置を 折り畳んだ構造は種々提案されている。同一出願人においても実開平2−148 216号は後方側尻上がりに斜めに折り畳んだものであり、又特開平2−295 402号は後方水平に折り畳んだ構造で、その折り畳み時に左右の砕土体を固定 する構成に関するものが提示されている。 Various structures have been proposed in which a wide crushing device that protrudes from the width of the tractor body when folded is mounted on the rear part of the tractor. Even in the same applicant, Japanese Utility Model Laid-Open No. 2-148 216 is a structure that is diagonally folded upward to the rear side, and Japanese Patent Laid-Open No. 2-295402 is a structure that is folded horizontally in the rear direction. A fixed configuration is presented.

前記した従来技術の後者は分割した砕土体の固定装置を回動部近傍に配設し、 この砕土体の側端部に固定装置の操作装置を配置して折り畳んだ装置の外側から 遠隔操作する技術である。しかしながら、この構成では移動する場合、前記回動 部近傍の固定装置に砕土体の自重のほとんどが振動衝撃となって集中するので、 この砕土装置が破損する等の問題があった。そこで本考案は砕土体の側端部に固 定装置を設けて解決しようとするものである。 In the latter of the above-mentioned conventional techniques, a divided crushed body fixing device is arranged in the vicinity of a rotating part, and an operating device of the fixing device is arranged at a side end of this crushed body to perform remote control from the outside of the folded device. It is a technology. However, with this configuration, when moving, most of the gravity of the crushed body concentrates on the fixing device in the vicinity of the rotating portion as a vibration impact, which causes a problem such as damage to the crushing apparatus. Therefore, the present invention is to solve the problem by providing a fixing device at the side end of the crushed body.
【0004】[0004]
前記の問題を解決するためにトラクタに装着するマストフレームの左右両側部 に砕土体を2分割して折り畳み可能に構成した砕土装置において、分割された砕 土体の側端部後面側にそれぞれ係合受部と係合片を配置して折り畳み時、自動係 合固着されることを特徴としたトラクタに装着される農用砕土装置を手提供した ものである。 In order to solve the above-mentioned problems, in a crushing device in which a crushed body is divided into two and can be folded at both left and right sides of a mast frame mounted on a tractor, the side ends of the divided crushed bodies are respectively attached to the rear surface side. The present invention provides an agricultural soil crushing device to be mounted on a tractor, which is characterized in that it is automatically engaged and fixed when folded by arranging a receiving portion and an engaging piece.

本考案を実施した砕土装置をトラクタに装着して折り畳む時、一方の砕土体を 後方に折り畳んで、次に他方の砕土体を後方に折り畳むとそれぞれの砕土体側端 部背面に突設した係合片と係合受部とが自動嵌合固着される。移動時に、連結さ れた砕土体の開き方向の力は固着部に掛かるが、従来技術で問題になった砕土体 自体の自重衝撃力は排除されるので軽量に製作できる。 When the crusher according to the present invention is mounted on a tractor and folded, when one crushed body is folded backward and then the other crushed body is folded backward, the engagement projecting on the rear surface of each crushed body side end is engaged. The piece and the engagement receiving portion are automatically fitted and fixed to each other. When moving, the force of the connected crushed body in the opening direction is applied to the fixed part, but the self-weight impact force of the crushed body itself, which has been a problem in the conventional technology, is eliminated, so that it can be made lightweight.

本考案を実施した図面に基づいて構成を説明する。 図1は本考案を実施した平面図で、仮想線は折り畳み時の砕土体の位置を示す 。図2は折り畳みの原理を示す機構図である。 ミッション2の左右にパイプフレームI14を突出し、パイプフレームI14 の端部にはアウタブラケット8を形成する。パイプフレームI14と同芯にパイ プフレームII16が配置され伝動ケース17と補助フレーム20とによって砕 土体13は支承されている。パイプフレームI14の後部でアウタブラケット8 には進行方向に向けて傾斜されて支軸9が設けられている。前記パイプフレーム II16の内側端にはインナブラケット15が固着され、前記アウタブラケット 8に挿入されて支軸9を介して砕土体13が後方斜めに折り畳み自在に構成され る。アウタブラケット8の後部にはフック板18が設けられ、パイプフレームI I16の後部に設けた固定板19とにコイル状の弾性体10を掛け渡してなる。 3は入力軸でトラクタのPTO6としてユニバーサルジョイントによって動力 が伝達される。21はクラッチ体で、パイプフレームI、II内を貫通する伝動 軸の接・離作用をする。17は伝動ケースで砕土体13を回転伝動する。 22 は係合受部で砕土体13の一方の側端部背面側に突出して設けられ、他方の砕土 体13には係合片23が設けられて図1の仮想線の位置で係合固着されている。 図3は要部の後面図で、図4は要部の部品斜視図を示したものである。係合片 23には縦ピン28が設けられている。係合受部22は先広がりV字状のガイド 板24の上部に横ピン26によって係合孔を有した係止板25が回動自在に載置 される。27は巻きバネで横ピン26に装着され係止板25をガイド板24に弾 着するものである。 次に係合時の作用について説明する。係合片23の縦ピン28は係合受部22 に接近する。この時、係合片23の先端縁は下方へ傾斜しているので先広がりの ガイド板24の下側へ移動する。同時に縦ピン28は係止板25を上方へ押し上 げながらガイド板24の先広がりの逆ハ字状の側面に倣って左右の砕土体13の 機械的ズレ分を吸収し、中心部へ移動して、ついに係止板25の係止孔へ嵌合し て固着される。この時係止板25は巻きバネ27によって常にガイド板24へ弾 着される。 図5は本考案の砕土装置をトラクタに装着した側面図で、一部を省略した図を 示す。1のマストフレームはトップリンク4、ロアリンク7とに連結され、油圧 アーム5によって連結されて昇降する。砕土体13は上部にカバー11、後面部 にレベラ12を配置してなり、仮想線は後方斜めに支軸9を支点として弾性体 10のバランサ力によって折り畳んだ状態を示している。 実作業時は砕土体13の実線の位置にあるが、適宜に固定装置によって一体固 着される。 The configuration will be described based on the drawings in which the present invention is implemented. FIG. 1 is a plan view of the present invention, in which the phantom line indicates the position of the crushed body when folded. FIG. 2 is a mechanism diagram showing the principle of folding. The pipe frame I14 is projected to the left and right of the mission 2, and the outer bracket 8 is formed at the end of the pipe frame I14. A pipe frame II16 is arranged concentrically with the pipe frame I14, and the crushed body 13 is supported by the transmission case 17 and the auxiliary frame 20. At the rear part of the pipe frame I14, the outer bracket 8 is provided with a support shaft 9 which is inclined in the traveling direction. An inner bracket 15 is fixed to the inner end of the pipe frame II16, and is inserted into the outer bracket 8 so that a crushed body 13 can be folded obliquely rearward via a support shaft 9. A hook plate 18 is provided at the rear portion of the outer bracket 8, and a coil-shaped elastic body 10 is laid over a fixed plate 19 provided at the rear portion of the pipe frame II16. An input shaft 3 is a tractor PTO 6 to which power is transmitted by a universal joint. Reference numeral 21 is a clutch body which acts on and off the transmission shaft penetrating the pipe frames I and II. Reference numeral 17 denotes a transmission case for rotating and transmitting the crushed body 13. Reference numeral 22 denotes an engagement receiving portion which is provided so as to project to the rear surface side of one side end portion of the crushed body 13, and an engaging piece 23 is provided on the other crushed body 13 to be fixedly engaged at the position of the phantom line in FIG. Has been done. FIG. 3 is a rear view of the main part, and FIG. 4 is a perspective view of parts of the main part. The engagement piece 23 is provided with a vertical pin 28. In the engagement receiving portion 22, a locking plate 25 having an engaging hole is rotatably mounted on the upper part of a V-shaped guide plate 24 by a lateral pin 26. A winding spring 27 is attached to the lateral pin 26 and elastically attaches the locking plate 25 to the guide plate 24. Next, the operation during engagement will be described. The vertical pin 28 of the engagement piece 23 approaches the engagement receiving portion 22. At this time, since the leading edge of the engaging piece 23 is inclined downward, it moves to the lower side of the guide plate 24 which is divergent. Simultaneously, the vertical pin 28 pushes up the locking plate 25 upwards, absorbs the mechanical deviation of the left and right crushed bodies 13 following the side of the guide plate 24 in the shape of an inverted C-shape, and moves to the center. Finally, it is fitted into the locking hole of the locking plate 25 and fixed. At this time, the locking plate 25 is always elastically attached to the guide plate 24 by the winding spring 27. FIG. 5 is a side view in which the crusher of the present invention is attached to a tractor, and a part of it is omitted. The mast frame 1 is connected to the top link 4 and the lower link 7, and is connected by the hydraulic arm 5 to move up and down. The crushed body 13 is provided with a cover 11 on the upper part and a leveler 12 on the rear surface part, and the imaginary line shows a state of being folded obliquely backward by the balancer force of the elastic body 10 with the support shaft 9 as a fulcrum. Although it is in the position of the solid line of the crushed body 13 during the actual work, it is integrally fixed by a fixing device as appropriate.

以上のように2分割された砕土体のそれぞれの側端部背面側に突出して係合受 部、係合片を設けたので、折り畳み時、自動係合固着されて安全である。しかも 側端部側であるので固着力が小さくて良いので固着部の構成が軽量で簡単にでき るという実益がある。 As described above, since the engaging receiving portion and the engaging piece are provided so as to project to the rear surface side of each side end portion of the crushed earth body divided into two, it is safe to be automatically engaged and fixed during folding. Moreover, since it is on the side end side, the fixing force may be small, so there is a real advantage that the fixing part can be made lightweight and simple.
