Description

本発明は、トラクタロワリンクに結合する牽引横バーの長手方向に複数の作業機を連結したトラクタ直装式作業機のスタンド保管機構に関する。   The present invention relates to a stand storage mechanism for a tractor directly mounted work machine in which a plurality of work machines are connected in the longitudinal direction of a pulling horizontal bar coupled to a tractor lower link.

トラクタのロワリンクに連結される牽引横バーの長手方向に沿って複数の作業機ユニットを装着したトラクタ直装式の作業機は、保管時の安定性が悪い関係で一般に保管スタンドを使用する場合が多い。   Tractor-mounted work machines equipped with multiple work equipment units along the longitudinal direction of the tow bar connected to the lower link of the tractor generally use a storage stand because of poor stability during storage. Many.

この種のトラクタ直装式作業機のスタンド保管機構としては、図９、図１０に示すように、作業機側の牽引横バー４に左右の係着金具７、７を固定するとともに、保管スタンド８の支柱１３先端付近を、作業機側係着金具７、７によって形成された縦方向のコの字形ガイドプレート９内に嵌合し、ガイドプレート９とスタンド先端付近相互に形成した通孔にピン５を挿入して保管スタンド８に支持させていた。なお、図は省略したが、牽引横バー４の軸方向にはカルチベータなどの作業機ユニットが後方へ向けて所定間隔で連結されており、牽引横バー４の中央部にトラクタのロワリンクに連結される結合アーム６ａ、６ｂ、６ｃが一体に固設されている。   As shown in FIGS. 9 and 10, the stand storage mechanism of this type of tractor directly mounted work machine includes fixing the left and right anchoring brackets 7 and 7 to the traction side bar 4 on the work machine side, 8 is fitted into a vertical U-shaped guide plate 9 formed by the work equipment side fittings 7, 7, and is inserted into a through hole formed between the guide plate 9 and the stand tip. The pin 5 was inserted and supported on the storage stand 8. Although not shown, work machine units such as a cultivator are connected at a predetermined interval in the axial direction of the tow horizontal bar 4 and connected to the lower link of the tractor at the center of the tow horizontal bar 4. The connecting arms 6a, 6b, 6c to be connected are fixed integrally.

このようなスタンド保管機構は、作業機に保管スタンド８を係着したまま所望の保管位置へ移動できるものであるが、トラクタロワリンクに連結した作業機の係着金具７に保管スタンド８を結合するには保管スタンド８を持ち上げたままの体勢で先端付近の通孔を係着金具７のガイドプレート９に設けた通孔に位置合わせをしてピン５を挿入しなければならないので作業性が悪く、重労働である。   Such a stand storage mechanism can move to a desired storage position with the storage stand 8 attached to the work machine, but the storage stand 8 is coupled to the attachment bracket 7 of the work machine connected to the tractor lower link. For this purpose, the pin 5 must be inserted by aligning the through hole in the vicinity of the tip to the through hole provided in the guide plate 9 of the anchoring bracket 7 while keeping the storage stand 8 lifted. It is bad and hard work.

従って、本発明の目的は、保管スタンドを装着したまま保管場所を移動でき、作業機と保管スタンドの脱着が容易なトラクタ直装式作業機のスタンド保管機構を提供することにある。   Accordingly, an object of the present invention is to provide a stand storage mechanism for a tractor- directly-mounted work machine in which a storage place can be moved while the storage stand is mounted, and the work machine and the storage stand can be easily detached.

上記目的を達成するために、本発明による作業機のスタンド保管機構は、後方に向けて作業ユニットを取り付けた牽引横バーの牽引アームをトラクタロアリンクに連結するトラクタ直装式作業機の保管機構であって、牽引横バーの中心から左右両側に固定した少なくとも２個所の係着金具と、この係着金具に対応する保管スタンドからなり、前記係着金具は、縦方向の相対するガイドプレートの上部外側縁辺間を係止バーで一体結合して前記牽引横バーに固定した構成になり、前記保管スタンドは、接地ベースフレームから上方へ向けて延在させた支柱の先端部分を前記係着金具のガイドプレート間に差し入れ可能な挿入部に形成してその先端部に前記係着金具の係止バーに係着されるフック状の掛け金具を一体に設けるとともに、この支柱の前記挿入部下部に前記係着金具のガイドプレート下端を係止する受け部を形成した構成になることを特徴とする。   In order to achieve the above object, a stand storage mechanism for a work machine according to the present invention is a storage mechanism for a tractor directly mounted work machine in which a traction arm of a horizontal traction bar to which a work unit is attached is connected to a tractor lower link. And comprising at least two anchoring brackets fixed to the left and right sides from the center of the pulling horizontal bar, and a storage stand corresponding to the anchoring brackets. The upper outer edge is integrally coupled with a locking bar and fixed to the pulling horizontal bar, and the storage stand has the engagement bracket with the tip end portion of the column extended upward from the grounding base frame. A hook-shaped hook that is formed in an insertion portion that can be inserted between the guide plates and is engaged with the engagement bar of the engagement fitting is integrally provided at the tip of the insertion plate. Characterized in that it comprises a structure forming a receiving portion for locking the guide plate lower end of the engagement Chakukanagu into the insertion subordinate unit.

保管スタンド１１の支柱１３先端の挿入柱体部１５を、牽引横バー４に固定した係着金具７のガイドプレート９、９間に差し入れ、掛け金具１６を係着金具７の係止バー１０に引っ掛けるだけで、保管スタンド１１はトラクタに連結された牽引横バー４に宙吊りに係着される。
保管スタンドを装着したまま所望の保管場所へ移動して保管スタンド１１を接地させるだけで、牽引横バー４の係着金具７が、保管スタンド１１の支柱１３に設けた受け部１７に係止される。その後、牽引横バー４の牽引アーム６ａ、６ｂ、６ｃをトラクタロワリンク３から外すことによって保管作業が完了する。
ロワリンク３を持ち上げると保管スタンド１１が宙吊りになり、手で保管スタンド１１を持ち上げ、受け部１７を前方へかわして下へ引けばよいので容易に保管スタンドを外すことができる。
このように、本発明によれば、ボルト孔の位置合わせやボルト締め作業を一切必要とせずに作業機を簡単に保管することができる。 The insertion column body 15 at the tip of the column 13 of the storage stand 11 is inserted between the guide plates 9 and 9 of the anchoring bracket 7 fixed to the pulling horizontal bar 4, and the hanging bracket 16 is attached to the locking bar 10 of the anchoring bracket 7. By simply hooking, the storage stand 11 is suspended from the tow bar 4 connected to the tractor.
By simply moving to a desired storage location with the storage stand attached and grounding the storage stand 11, the anchoring bracket 7 of the tow bar 4 is locked to the receiving portion 17 provided on the column 13 of the storage stand 11. The Thereafter, the storage operation is completed by removing the traction arms 6 a, 6 b, 6 c of the traction horizontal bar 4 from the tractor lower link 3.
When the lower link 3 is lifted, the storage stand 11 is suspended in the air, and the storage stand 11 can be lifted by hand and the receiving portion 17 can be moved forward and pulled down, so that the storage stand can be easily removed.
Thus, according to the present invention, the work implement can be easily stored without requiring any bolt hole positioning or bolt tightening operations.

Any other structure may be used as long as it is strong enough to support the traction horizontal bar 4 to which the machine unit 1 is attached.

次に本発明によるスタンド保管機構の脱着作用を説明する。
図１のように、作業機ユニット１を取付けた牽引横バー４の牽引アーム６ａ、６ｂ、６ｃをトラクタ２のロワリンク３に連結して持ち上げた状態で保管スタンド１１の支柱１３の挿入柱体部１５を差し入れて（図４）上方へ突出させた後（図５）、支柱１３の先端を前方へずらせて掛け金具１６を係着金具７の係止バー１０に係合させる（図６）。この状態では図１に示すように、保管スタンド１１は作業機の牽引横バー４に係着されたままトラクタ２のロワリンク３によって持ち上げられ、所望の保管場所に搬送することができる。
しかる後、図８のように保管スタンド１１の接地ベースフレーム１２を地面に接地させると、図７に示すように牽引横バー４に固定した係着金具７のガイドプレート９の下端が支柱１３の受け部１７に係止され、作業機ユニット１を装着した牽引横バー４が左右の保管スタンド１１、１１に支持され、牽引横バー４の牽引アーム６ａ、６ｂ、６ｃをトラクタロワリンク３から外すことで保管作業が完了する。
保管スタンド１１を外すときは、ロワリンク３を持ち上げると図６、図１のように保管スタンド１１が宙吊りになるので、手で保管スタンド１１を持ち上げ、受け部１７を前方へかわして下へ引けばよい。 Next, the detaching action of the stand storage mechanism according to the present invention will be described.
As shown in FIG. 1, the traction arm 6 a, 6 b, 6 c of the traction horizontal bar 4 to which the work machine unit 1 is attached is connected to the lower link 3 of the tractor 2 and lifted to insert the column 13 of the column 13 of the storage stand 11. After inserting 15 (FIG. 4) and projecting upward (FIG. 5), the front end of the support column 13 is shifted forward to engage the latch 16 with the locking bar 10 of the anchor 7 (FIG. 6). In this state, as shown in FIG. 1, the storage stand 11 can be lifted by the lower link 3 of the tractor 2 while being attached to the pulling horizontal bar 4 of the work machine, and can be transported to a desired storage location.
Thereafter, when the grounding base frame 12 of the storage stand 11 is grounded as shown in FIG. 8, the lower end of the guide plate 9 of the anchoring metal fitting 7 fixed to the pulling horizontal bar 4 as shown in FIG. The tow bar 4 that is locked to the receiving portion 17 and is equipped with the work machine unit 1 is supported by the left and right storage stands 11 and 11, and the tow arms 6 a, 6 b, and 6 c of the tow bar 4 are removed from the tractor lower link 3. This completes the storage operation.
When removing the storage stand 11, when the lower link 3 is lifted, the storage stand 11 is suspended in the air as shown in FIGS. Good.
