Description

本発明は、走行機体に設けられた走行機体側カプラに着脱自在に連結する作業機側カプラを支持する作業機のカプラ支持装置に関する。   The present invention relates to a coupler support device for a working machine that supports a working machine side coupler that is detachably connected to a traveling machine side coupler provided in the traveling machine body.

従来、一般的にトラクターと呼ばれる農作業用の走行機体には、耕耘作業機等の作業機が装着されるようになっている。このような走行機体は、走行機体側カプラに作業機側カプラを接続することで前記作業機に電力や油圧による動力を供給するとともに、作業機との間の信号の伝達を行っている。   2. Description of the Related Art Conventionally, a working machine such as a tillage working machine is attached to a traveling machine body for farm work generally called a tractor. In such a traveling machine body, a working machine side coupler is connected to the traveling machine body side coupler to supply power to the working machine by electric power or hydraulic pressure and to transmit signals to and from the working machine.

このような走行機体に装着される作業機は、例えば、特許文献1に記載されている。この作業機270は、図8(側面図)に示すように、走行機体290の後部に設けられた三点リンク連結機構291に着脱可能に取り付けられて圃場を耕耘する耕耘作業機である。この作業機270は、ロータリ耕耘作業部271に耕深検知センサを設け、この耕深検知センサからの検知信号を走行機体側に設けた制御部に入力した検知結果に応じて自動的に耕深制御を行うように構成されている。このため、走行機体側の制御部と作業機側の耕深検知センサとを電気的に接続するために走行機体側に走行機体側カプラ272を設け、作業機側に作業機側カプラ273を設けている。   A working machine mounted on such a traveling machine body is described in Patent Document 1, for example. As shown in FIG. 8 (side view), the work machine 270 is a tilling work machine that is detachably attached to a three-point link coupling mechanism 291 provided at the rear portion of the traveling machine body 290 to plow a farm field. This working machine 270 is provided with a tilling depth detection sensor in the rotary tillage working unit 271 and automatically makes a tilling depth in accordance with a detection result input from a detection signal from the tilling depth detection sensor to a control unit provided on the traveling machine body side. It is configured to perform control. Therefore, a traveling machine body side coupler 272 is provided on the traveling machine body side and a working machine side coupler 273 is provided on the working machine side in order to electrically connect the control unit on the traveling machine side and the plowing depth detection sensor on the working machine side. ing.

走行機体側カプラ272は、三点リンク連結機構291に取り付けられたヒッチフレーム274の上部に固定した状態で取り付けられている。一方、作業機側カプラ273は、ヒッチフレーム274を取り付けるトップマスト275に取り付けられたチェーン276を介して吊持ち状に取り付けられている。このチェーン276の基端部の固着位置は、走行機体側カプラ272と作業機側カプラ273が係合している状態で、前方に引っ張られた緊張状態となるように配置されている。またチェーン276の長さは、作業機側カプラ273に接続されたハーネス277の緊張に先行してチェーン276が緊張するとともに、自然垂下状態で作業機270を持ち上げたときに走行機体290の運転席に搭乗した作業者が後ろ向きになって手を延ばせば容易に手が届く長さに設定されている。   The traveling machine body side coupler 272 is attached in a state of being fixed to the upper part of the hitch frame 274 attached to the three-point link coupling mechanism 291. On the other hand, the work machine side coupler 273 is attached in a suspended manner via a chain 276 attached to a top mast 275 to which the hitch frame 274 is attached. The fixing position of the base end portion of the chain 276 is arranged so as to be in a tension state pulled forward while the traveling machine body side coupler 272 and the work machine side coupler 273 are engaged. The length of the chain 276 is such that the chain 276 is tensioned prior to the tension of the harness 277 connected to the work machine side coupler 273, and when the work machine 270 is lifted in the natural hanging state, the driver's seat of the traveling machine body 290 It is set to a length that can be easily reached if the worker who has boarded the vehicle faces backwards and reaches out.

このため、作業機270を走行機体290に取り付ける場合には、作業機270を走行機体290に装着した後に、作業者は走行機体290の運転席に搭乗して後方側に向いて、垂れ下がっている作業機側カプラ273を持ち上げて走行機体側カプラ272に押し付けて両カプラを接続する。また作業機側カプラ273を走行機体側カプラ272から取り外す場合には、走行機体290を前進走行させるだけでよい。   For this reason, when attaching the work machine 270 to the traveling machine body 290, after the work machine 270 is mounted on the traveling machine body 290, the operator gets on the driver's seat of the traveling machine body 290 and hangs down toward the rear side. The work machine side coupler 273 is lifted and pressed against the traveling machine body side coupler 272 to connect both couplers. Further, when the work machine side coupler 273 is removed from the traveling machine body side coupler 272, the traveling machine body 290 only needs to travel forward.

A method of using the coupler support device 50 effective in such a case will be described.

図7(a)は、平均よりある程度腕が長い体格の作業者が作業機側カプラ38−1,38−2に走行機体側カプラ96−1,96−2を接続する場合のカプラ支持装置50の使用法について説明する説明図である。   FIG. 7A shows a coupler support device 50 in the case where an operator whose physique is somewhat longer than the average connects the traveling machine side couplers 96-1 and 96-2 to the working machine side couplers 38-1 and 38-2. It is explanatory drawing explaining the usage of.

走行機体90および作業機本体10を使用して作業を行う作業者が平均よりある程度腕が長い体格の人物である場合、本作業者は、図6(a)に示したボルト69のネジ部が直線フレーム62のネジ挿通孔67−2に挿通しトップマスト5の右側面51のネジ孔52−2に螺入した状態でボルト69を緩め、直線フレーム62の先端側を走行機体90の反対側に傾けた状態で、ボルト69のボルト頭を締め付けることでカプラ支持装置50の直線フレーム62をトップマスト5の右側面51に固定する。次に、本作業者は、作業機側カプラ38−1,38−2の結合面45を走行機体90側に向けた状態で取り付けボルト63とナット64を締め付けることで、カプラ取付固定部71を直線フレーム62に固定する。   When the worker who uses the traveling machine body 90 and the work machine main body 10 is a person with a physique whose arm is somewhat longer than the average, the worker has the screw part of the bolt 69 shown in FIG. The bolt 69 is loosened while being inserted into the screw insertion hole 67-2 of the straight frame 62 and screwed into the screw hole 52-2 of the right side surface 51 of the top mast 5, and the front end side of the straight frame 62 is opposite to the traveling machine body 90. The straight frame 62 of the coupler support device 50 is fixed to the right side surface 51 of the top mast 5 by tightening the bolt heads of the bolts 69 while tilted to the right. Next, the worker tightens the attachment bolt 63 and the nut 64 in a state where the coupling surface 45 of the work machine side couplers 38-1 and 38-2 faces the traveling machine body 90 side, whereby the coupler attachment fixing portion 71 is secured.
