　特許文献１に記載の収穫機では、ラジエータのメンテナンスを行う際に、第一冷却装置や第二冷却装置を取り外さなければならず、ラジエータのメンテナンスを容易に行う点で改善の余地がある。 In the harvester described in Patent Document 1, the first cooling device and the second cooling device must be removed when performing radiator maintenance, and there is room for improvement in terms of facilitating radiator maintenance.
　上記状況に鑑み、ラジエータのメンテナンスを容易に行うことが可能な収穫機が要望されている。 In view of the above situation, there is a demand for a harvester that can easily perform radiator maintenance.
　本発明の特徴は、水冷式のエンジンと、前記エンジンに対して機体左右方向の外側に配置され、前記エンジン用の冷却水を冷却するラジエータと、機体左右方向で前記エンジンと前記ラジエータとの間に配置され、前記ラジエータに冷却風を供給する冷却ファンと、前記ラジエータに対して機体左右方向の外側に配置される第一冷却装置と、前記ラジエータに対して機体左右方向の外側に配置される第二冷却装置と、を備えている収穫機であって、前記第一冷却装置を支持する第一支持フレームと、前記第二冷却装置を支持する第二支持フレームと、を備え、前記第一支持フレームは、第一揺動軸心周りにおいて、前記第一冷却装置が使用時の姿勢となる第一閉位置と、前記第一冷却装置が機体左右方向の外側に開いた姿勢となる第一開位置とに亘って揺動開閉可能に構成され、前記第二支持フレームは、第二揺動軸心周りにおいて、前記第二冷却装置が使用時の姿勢となる第二閉位置と、前記第二冷却装置が機体左右方向の外側に開いた姿勢となる第二開位置とに亘って揺動開閉可能に構成されていることにある。 A feature of the present invention is a water-cooled engine, a radiator arranged outside the engine in the left-right direction of the fuselage for cooling cooling water for the engine, and a space between the engine and the radiator in the left-right direction of the fuselage. a cooling fan for supplying cooling air to the radiator; a first cooling device arranged outside the radiator in the lateral direction of the aircraft; and a first cooling device arranged outside the radiator in the lateral direction of the aircraft. a second cooling device, comprising: a first support frame that supports the first cooling device; a second support frame that supports the second cooling device; The support frame has a first closed position, in which the first cooling device is in use, and a first position, in which the first cooling device is opened outward in the left-right direction of the aircraft body, around the first swing axis. The second support frame is configured to be swingably openable and closable between an open position and a second closed position, at which the second cooling device assumes a posture when in use, and the second support frame, around the second swing axis. (2) The cooling device is configured to be swingably openable and closable between a second open position in which the cooling device is opened outward in the left-right direction of the machine body.
　本特徴構成によれば、第一支持フレームを第一揺動軸心周りで揺動させて第一開位置に位置変更し、第二支持フレームを第二揺動軸心周りで揺動させて第二開位置に位置変更すると、ラジエータのうち機体左右方向の外側の側面（横外側面）が開放されることになる。これにより、ラジエータのメンテナンスを行う際に、ラジエータの横外側面に対して機体左右方向の外側から容易にアクセスすることができる。すなわち、ラジエータのメンテナンスを容易に行うことが可能な収穫機を実現することができる。 According to this characteristic configuration, the first support frame is rocked around the first rocking axis to change the position to the first open position, and the second support frame is rocked around the second rocking axis. When the position is changed to the second open position, the outer side surface (horizontal outer side surface) of the radiator in the left-right direction of the fuselage is opened. As a result, when performing maintenance on the radiator, it is possible to easily access the lateral outer surface of the radiator from the outside in the left-right direction of the fuselage. That is, it is possible to realize a harvesting machine that allows easy maintenance of the radiator.
　また、第一冷却装置の裏面及び第二冷却装置の裏面もそれぞれ開放されることになる。これにより、第一冷却装置及び第二冷却装置のメンテナンスを容易に行うことができる。 In addition, the back side of the first cooling device and the back side of the second cooling device are also opened. This facilitates maintenance of the first cooling device and the second cooling device.
　さらに、本発明において、前記第一冷却装置及び前記第二冷却装置は、前記第二冷却装置が前記第一冷却装置に対して機体左右方向の外側に位置し、かつ、側面視で互いに重複する状態で配置され、前記第二支持フレームを前記第二開位置に位置変更することにより、前記第一支持フレームを前記第一開位置に位置変更可能なように構成されていると好適である。 Further, in the present invention, the first cooling device and the second cooling device are arranged such that the second cooling device is positioned outside the first cooling device in the left-right direction of the fuselage and overlaps each other in a side view. and the position of the first support frame can be changed to the first open position by changing the position of the second support frame to the second open position.

By changing the position of the second support frame to the second open position, the first support frame can be changed to the first open position without the second cooling device interfering with the first cooling device.
　さらに、本発明において、前記第二支持フレームは、前記第一支持フレームに当たって前記第二閉位置に位置決めされるように構成されていると好適である。 Furthermore, in the present invention, it is preferable that the second support frame is configured to abut against the first support frame and be positioned at the second closed position.
　本特徴構成によれば、第二支持フレームが第一支持フレームに当たることにより、第二支持フレームを第二閉位置に確実に位置決めすることができる。その際、第一支持フレームを利用することにより、第二支持フレームを第二閉位置に位置決めする構造を簡素に構成することができる。 According to this characteristic configuration, the second support frame can be reliably positioned at the second closed position by abutting the second support frame against the first support frame. In this case, by using the first support frame, the structure for positioning the second support frame at the second closed position can be simply constructed.

Therefore, when opening and closing the first support frame and the second support frame by swinging, it is not necessary to lift them. As a result, the first support frame and the second support frame can be opened and closed by swinging with a small force.
　さらに、本発明において、前記第一揺動軸心及び前記第二揺動軸心は、機体前後方向で互いに異なる位置に配置されていると好適である。 Furthermore, in the present invention, it is preferable that the first swing axis and the second swing axis are arranged at different positions in the longitudinal direction of the aircraft body.
　本特徴構成によれば、第一支持フレームを揺動開閉可能に支持する構造と第二支持フレームを揺動開閉可能に支持する構造とを互いに干渉させることなく、これらを構成することができる。 According to this characteristic configuration, the structure for supporting the first support frame so as to be swingably openable and the structure for supporting the second support frame so that it can be swingably opened and closed can be configured without interfering with each other.

　本特徴構成によれば、第一導入部材及び第一導出部材が第一冷却装置に対して同じ側（第一支持部が位置する側）に位置することになる。これにより、第一導入部材及び第一導出部材を容易にまとめることができる。また、第一導入部材及び第一導出部材が第一揺動軸心に沿って延びているため、第一支持フレームを揺動開閉する際に、第一導入部材及び第一導出部材をねじれ難くすることができる。 According to this characteristic configuration, the first introduction member and the first extraction member are positioned on the same side (the side on which the first support portion is positioned) with respect to the first cooling device. Thereby, the first introduction member and the first extraction member can be easily put together. Further, since the first introduction member and the first derivation member extend along the first pivot axis, the first introduction member and the first derivation member are less likely to be twisted when the first support frame is pivotally opened and closed. can do.

　本特徴構成によれば、第二導入部材及び第二導出部材が第二冷却装置に対して同じ側（第二支持部が位置する側）に位置することになる。これにより、第二導入部材及び第二導出部材を容易にまとめることができる。また、第二導入部材及び第二導出部材が第二揺動軸心に沿って延びているため、第二支持フレームを揺動開閉する際に、第二導入部材及び第二導出部材をねじれ難くすることができる。 According to this characteristic configuration, the second introduction member and the second extraction member are located on the same side (the side where the second support portion is located) with respect to the second cooling device. Thereby, the second introduction member and the second extraction member can be easily put together. Further, since the second introduction member and the second derivation member extend along the second pivot axis, the second introduction member and the second derivation member are less likely to be twisted when the second support frame is pivotally opened and closed. can do.
　さらに、本発明において、前記第一支持フレームは、前記第一閉位置に位置する状態において、着脱可能な第一固定具によって固定され、前記第一固定具が取り付けられることにより、前記第一支持フレームを前記第一開位置に位置保持する第一保持部を備えていると好適である。 Further, in the present invention, the first support frame is fixed by a detachable first fixture in a state of being positioned at the first closed position, and the first support frame is attached by attaching the first fixture.

　ここで、第一固定具が第一保持部に取り付けられている状態では、第一支持フレームを第一閉位置に位置変更することができず、第一支持フレームを第一閉位置に位置変更するためには、第一固定具を第一保持部から取り外す必要がある。これにより、第一支持フレームを第一閉位置に位置変更するために第一固定具を第一保持部から取り外した後に、第一固定具によって第一支持フレームを第一閉位置に固定するべきことを、作業者に意識付けすることができる。 Here, when the first fixture is attached to the first holding part, the position of the first support frame cannot be changed to the first closed position, and the position of the first support frame is changed to the first closed position. To do so, the first fixture must be removed from the first holding part. Thereby, after removing the first fastener from the first retainer to reposition the first support frame to the first closed position, the first fastener should secure the first support frame in the first closed position. This can be made conscious of the operator.

Next, a method for opening and closing the first support frame 28, the second support frame 30 and the third support frame 32 will be described with reference to FIGS. 9 to 11. FIG.
　先ず、図９に示すように、第二オイルクーラ２３（後側の固定部２３ａ）を第二支持フレーム３０に固定しているボルトＢ５を、第二支持フレーム３０から取り外す。これにより、第三支持フレーム３２の閉位置への固定が解除されることになる。そして、第三支持フレーム３２を揺動軸心Ｚ２周りで前側に揺動することにより、第三支持フレーム３２を開位置に位置変更することができる。すなわち、第三支持フレーム３２は、揺動軸心Ｚ２周りで前側に揺動して開位置に位置変更されるように構成されている。 First, as shown in FIG. 9, the bolt B5 that secures the second oil cooler 23 (fixed portion 23a on the rear side) to the second support frame 30 is removed from the second support frame 30. As a result, the third support frame 32 is released from the closed position. By swinging the third support frame 32 forward about the swing axis Z2, the position of the third support frame 32 can be changed to the open position. That is, the third support frame 32 is configured to swing forward about the swing axis Z2 to be changed to the open position.

The holding portion 26Ba is configured to hold the third support frame 32 at the open position by attaching the bolt B5 that has fixed the rear fixing portion 23a to the second support frame 30. As shown in FIG. With the third support frame 32 changed to the open position, by attaching the bolt B5 to the holding portion 26Ba, the third support frame 32 is about to swing toward the closed position about the swing axis Z2. Also, the third support frame 32 comes into contact with the bolt B5 and is prevented from swinging.
　次に、図１０に示すように、第二支持フレーム３０（固定部３０ｂ）を第一支持フレーム２８に固定しているボルトＢ４を、第一支持フレーム２８から取り外す。これにより、第二支持フレーム３０の閉位置への固定が解除されることになる。そして、第二支持フレーム３０を揺動軸心Ｚ３周りで後側に揺動することにより、第二支持フレーム３０を開位置に位置変更することができる。すなわち、第二支持フレーム３０は、揺動軸心Ｚ３周りで後側に揺動して開位置に位置変更されるように構成されている。 Next, as shown in FIG. 10, the bolts B4 that fix the second support frame 30 (fixed portion 30b) to the first support frame 28 are removed from the first support frame 28.

Since the contact portion 30c contacts the rear vertical frame 26D, the second support frame 30 does not swing rearward about the swing axis Z3 in the open position.
　このように、第三支持フレーム３２を開位置に位置変更することにより、第二支持フレーム３０を開位置に位置変更可能なように構成されている。第二支持フレーム３０は、第三支持フレーム３２と異なる方向に揺動して開閉するように構成されている。言い換えると、第三支持フレーム３２は、第二支持フレーム３０と異なる方向に揺動して開閉するように構成されている。 In this manner, the position of the second support frame 30 can be changed to the open position by changing the position of the third support frame 32 to the open position.

The holding portion 26Da is configured to hold the second support frame 30 at the open position by attaching the bolt B4 that has fixed the fixing portion 30b to the first support frame 28 . With the second support frame 30 changed to the open position, by attaching the bolt B4 to the holding portion 26Da, the second support frame 30 is about to swing toward the closed position about the swing axis Z3. Also, the second support frame 30 comes into contact with the bolt B4 and is prevented from swinging.
　次に、図１１に示すように、第一オイルクーラ２１（後側の上下の固定部２１ａ）を中縦フレーム２６Ｃに固定している二本のボルトＢ１を、中縦フレーム２６Ｃから取り外す。これにより、第一支持フレーム２８の閉位置への固定が解除されることになる。そして、第一支持フレーム２８を揺動軸心Ｚ２周りで前側に揺動することにより、第一支持フレーム２８を開位置に位置変更することができる。すなわち、第一支持フレーム２８は、揺動軸心Ｚ２周りで前側に揺動して開位置に位置変更されるように構成されている。 Next, as shown in FIG. 11, the two bolts B1 fixing the first oil cooler 21 (rear upper and lower fixing portions 21a) to the middle vertical frame 26C are removed from the middle vertical frame 26C. As a result, the first support frame 28 is released from the closed position. By swinging the first support frame 28 forward about the swing axis Z2, the position of the first support frame 28 can be changed to the open position. That is, the first support frame 28 is configured to swing forward about the swing axis Z2 to be changed to the open position.
　このように、第二支持フレーム３０を開位置に位置変更することにより、第一支持フレーム２８を開位置に位置変更可能なように構成されている。第一支持フレーム２８及び第二支持フレーム３０は、互いに異なる方向に揺動して開閉するように構成されている。 In this way, the position of the first support frame 28 can be changed to the open position by changing the position of the second support frame 30 to the open position.
