　新興国においては、トラクタは様々な用途で使用されており、バッテリへの過負荷となることがある。具体的には、大型コンバインの上にトラクタを載せ、その出力をコンバインの収穫や走行機能の動力源として使用することがある。この場合、通常のトラクタとしての使用よりもバッテリへの負荷が高い。よって、通常のバッテリよりも容量が大きいバッテリを搭載して作業を行うことが望まれる。しかし、従来の作業機において、容量が大きいバッテリを搭載しようとしても、バッテリの寸法が異なるため、支持体にバッテリを安定して固定することができなかった。 ト ラ In emerging countries, tractors are used for a variety of purposes and may overload the battery. Specifically, a tractor may be mounted on a large combine, and the output of the tractor may be used as a power source for harvesting and running functions of the combine. In this case, the load on the battery is higher than the use as a normal tractor.

　次いで、図４及び図５に基づいて、第２バッテリ５２を搭載する態様に説明する。第２バッテリ５２は、調整部材６２の上側に位置する上方空間内に収容される。第２バッテリ５２は、調整部材６２が配置された状態で、ベース部材６１に取り付けられる。 Next, an embodiment in which the second battery 52 is mounted will be described with reference to FIGS. The second battery 52 is housed in an upper space located above the adjustment member 62. The second battery 52 is attached to the base member 61 with the adjustment member 62 arranged.
　調整部材６２は、ベース部材６１に当接する当接部６２ｅと、ベース部材６１から離れる方向に向かって当接部６２ｅから延出する壁部６２ｄと、壁部６２ｄに連なり、かつベース部材６１に沿って延びる調整ベース部６２ａと、を有する。当接部６２ｅは、ベース部材６１の上面と当接し、ボルト及びナットなどの締結部材によってベース部材６１に固定されている。当接部６２ｅは、複数設けられており、右第１取付部６１ｂｌよりも第２バッテリから離れる側（本実施の形態における右側）と、左第１取付部６１ｂｒよりも第２バッテリから離れる側（本実施の形態における左側）と、に少なくとも設けられていてよい。本実施の形態は、右第１取付部６１ｂｌよりも右側の右当接部６２ｅｌと、左第１取付部６１ｂｒよりも左側の左当接部（図示せず）と、第２バッテリ５２の第２前面５２ａよりも離れる側の前当接部６２ｅｆと、を有する。 The adjusting member 62 is continuous with the contact portion 62e contacting the base member 61, the wall portion 62d extending from the contact portion 62e in a direction away from the base member 61, and the wall member 62d. And an adjustment base portion 62a extending along. The contact portion 62e contacts the upper surface of the base member 61, and is fixed to the base member 61 by a fastening member such as a bolt and a nut. A plurality of contact portions 62e are provided, the side farther from the second battery than the right first mounting portion 61bl (the right side in the present embodiment), and the side farther from the second battery than the first left mounting portion 61br. (The left side in the present embodiment). In the present embodiment, the right contact portion 62el on the right side of the right first attachment portion 61bl, the left contact portion (not shown) on the left side of the left first attachment portion 61br, and the second battery 52 (2) a front contact portion 62 ef on the side away from the front surface 52 a.
　壁部６２ｄは、ベース部材６１から離れる方向に延びている。本実施の形態の壁部６２ｄは、当接部６２ｅに直交し、上側に延びている。壁部６２ｄの長さ（高さ）は、ベース部材６１のベース部６１ａと調整ベース部６２ａとの間の空間の高さとなる。調整ベース部６２ａは、ベース部材６１のベース部６１ａに沿って延び、平面方向に延びている。調整ベース部６２ａは、板状である。調整ベース部６２ａの上面は、第２バッテリ５２の第２下面５２ｆに対向して配置されており、第２下面５２ｆに当接してよい。調整ベース部６２ａとベース部６１ａは、離間しており、その間に空間Ｓが形成されている。 The wall portion 62d extends in a direction away from the base member 61. The wall portion 62d of the present embodiment is orthogonal to the contact portion 62e and extends upward. The length (height) of the wall portion 62d is the height of the space between the base portion 61a of the base member 61 and the adjustment base portion 62a. The adjustment base portion 62a extends along the base portion 61a of the base member 61, and extends in a planar direction. The adjustment base 62a has a plate shape. The upper surface of the adjustment base portion 62a is disposed to face the second lower surface 52f of the second battery 52, and may be in contact with the second lower surface 52f. The adjustment base portion 62a and the base portion 61a are separated from each other, and a space S is formed therebetween.
　調整部材６２は、ベース部材６１の第１取付部６１ｂを覆うように配置される。調整部材６２は、ベース部材６１と第２バッテリ５２の間に配置されている。具体的には、調整部材６２の調整ベース部６２ａは、ベース部材６１の第１取付部６１ｂを覆い、かつベース部材６１と第２バッテリ５２の間に配置されている。第１バッテリ５１の寸法と第２バッテリ５２の寸法が異なっているため、第２バッテリ５２を直接ベース部材６１に取り付けようとすると、第１取付部６１ｂが第２バッテリ５２に当たるおそれがある。しかし、調整部材６２がベース部材６１の第１取付部６１ｂを覆うため、第２バッテリ５２を搭載する場合における第２バッテリ５２と第１取付部６１ｂの干渉を抑制できる。よって、第１バッテリ５１を搭載する作業機において、第２バッテリ５２をも搭載することができる。 The adjustment member 62 is arranged so as to cover the first mounting portion 61b of the base member 61. The adjustment member 62 is disposed between the base member 61 and the second battery 52. Specifically, the adjustment base portion 62a of the adjustment member 62 covers the first attachment portion 61b of the base member 61 and is disposed between the base member 61 and the second battery 52. Since the dimensions of the first battery 51 and the dimensions of the second battery 52 are different, if the second battery 52 is directly attached to the base member 61, the first attachment portion 61b may hit the second battery 52. However, since the adjustment member 62 covers the first attachment portion 61b of the base member 61, interference between the second battery 52 and the first attachment portion 61b when the second battery 52 is mounted can be suppressed. Therefore, in the working machine on which the first battery 51 is mounted, the second battery 52 can also be mounted.
　調整部材６２は、第２バッテリ５２が取り付けられる第２取付部６２ｂを有する。第２取付部６２ｂは、一対の対向面と対向面を繋ぐ連結面を有する断面コ字状の部材によって構成される。連結面は、上側に向かって配置されている。第２取付部における一対の対向面の側縁と連結面の側縁とが、第２バッテリ５２の６面のいずれかに当接し、第２バッテリ５２の移動を規制する。本実施の形態の第２取付部は、第２バッテリ５２の第２右側面５２ｃに当接する右第２取付部６２ｂｌと、第２バッテリ５２の第２左側面５２ｄに当接する左第２取付部６２ｂｒと、を有する。このように、第２バッテリ５２の対向する面を第２取付部６２ｂに挟むことにより、第２バッテリ５２を安定して支持することができる。 The adjusting member 62 has a second mounting portion 62b to which the second battery 52 is mounted. The second mounting portion 62b is configured by a member having a U-shaped cross section having a pair of opposing surfaces and a connecting surface connecting the opposing surfaces. The connection surface is arranged upward. The side edges of the pair of opposing surfaces and the side edge of the connection surface in the second mounting portion abut on one of the six surfaces of the second battery 52 to regulate the movement of the second battery 52. The second mounting portion of the present embodiment includes a right second mounting portion 62bl that contacts the second right side surface 52c of the second battery 52, and a left second mounting portion that contacts the second left side surface 52d of the second battery 52. 62 br. Thus, the second battery 52 can be stably supported by sandwiching the facing surface of the second battery 52 between the second mounting portions 62b.
　このような調整部材６２を有することにより、第１バッテリ５１と異なる寸法の第２バッテリ５２とを共通のベース部材６１に固定できる。第１バッテリ５１を搭載する場合と第２バッテリ５２を搭載する場合において、共通のベース部材６１を用いることができ、汎用性を高めることができる。大幅な設計変更や複数の作業機を購入することなく、寸法の異なる第１バッテリ５１及び第２バッテリ５２の両方を選択して搭載することができる。 調整 By having such an adjusting member 62, the first battery 51 and the second battery 52 having different dimensions can be fixed to the common base member 61. When the first battery 51 is mounted and when the second battery 52 is mounted, a common base member 61 can be used, and versatility can be improved. It is possible to select and mount both the first battery 51 and the second battery 52 having different dimensions without significantly changing the design or purchasing a plurality of working machines.
　調整部材６２は、第１アース部６１ｃと連結されている。本実施の形態では、調整部材６２の当接部６２ｅが第１アース部６１ｃと連結されている。調整部材６２は、第２バッテリ５２のアースコード５２ｘと接続される第２アース部６２ｃを有する。寸法の異なるバッテリでは、アースコードの長さや位置が異なることがある。調整部材６２を介してベース部材６１と第２バッテリのアースコードを接続することができる。また、調整部材６２は、第１アースコードを覆うように配置される。調整部材６２がベース部材６１の第１アース部６１ｃを覆うため、第２バッテリ５２を搭載する場合に、第２バッテリ５２と第１アース部６１ｃの干渉を抑制できる。よって、第１バッテリ５１を搭載する作業機において、第２バッテリ５２をも搭載することができる。 The adjustment member 62 is connected to the first ground portion 61c. In the present embodiment, the contact portion 62e of the adjustment member 62 is connected to the first ground portion 61c. The adjustment member 62 has a second ground portion 62c connected to the ground cord 52x of the second battery 52. Batteries of different dimensions may have different lengths and locations of ground cords. The base member 61 and the earth cord of the second battery can be connected via the adjustment member 62. Further, the adjusting member 62 is arranged so as to cover the first ground cord. Since the adjustment member 62 covers the first ground portion 61c of the base member 61, when the second battery 52 is mounted, interference between the second battery 52 and the first ground portion 61c can be suppressed. Therefore, in the working machine on which the first battery 51 is mounted, the second battery 52 can also be mounted.
　図４に示すように、固定部材６３によって、第２バッテリ５２がベース部材６１に固定されている。固定部材６３の第１固定部６３ａは、第２バッテリ５２のベース部材６１と反対側の面である第２上面５２ｅと、第２前面５２ａと、に接する。第２固定部６３ｂは、調整部材６２がベース部材６１に取り付けられ、かつ第２バッテリ５２が調整部材６２に取り付けられた状態において、調整部材６２に着脱可能に接続される。固定部材６３によって、第２バッテリ５２を調整部材６２に締め付け固定することができる。このように、共通の固定部材６３によって第１バッテリ５１及び第２バッテリ５２をベース部材６１に固定することができる。 第 As shown in FIG. 4, the second battery 52 is fixed to the base member 61 by the fixing member 63. The first fixing portion 63a of the fixing member 63 is in contact with a second upper surface 52e, which is a surface opposite to the base member 61 of the second battery 52, and a second front surface 52a. The second fixing portion 63b is detachably connected to the adjusting member 62 in a state where the adjusting member 62 is attached to the base member 61 and the second battery 52 is attached to the adjusting member 62. The second battery 52 can be tightened and fixed to the adjustment member 62 by the fixing member 63. As described above, the first battery 51 and the second battery 52 can be fixed to the base member 61 by the common fixing member 63.
　調整部材６２がベース部材６１に取り付けられ、かつ第２バッテリ５２が調整部材６２に取り付けられた状態において、ベース部材６１と調整ベース部６２ａとの間に空間Ｓが設けられている。ベース部材６１の複数の第１取付部６１ｂは、空間Ｓ内に配置されている。ベース部材６１と調整ベース部６２ａとの間に空間Ｓに第１取付部６１ｂが配置されているため、第１取付部６１ｂと第２バッテリ５２の干渉を防ぐことができる。また、ベース部材６１と調整ベース部６２ａとの間に空間Ｓが形成されることにより、当該空間の空気の流れによるエンジンの冷却効果を得ることができる。特に、後述する開口を有する支持体において、好適な冷却効果を得ることができる。 In the state where the adjustment member 62 is attached to the base member 61 and the second battery 52 is attached to the adjustment member 62, a space S is provided between the base member 61 and the adjustment base portion 62a. The plurality of first attachment portions 61b of the base member 61 are arranged in the space S. Since the first attachment portion 61b is disposed in the space S between the base member 61 and the adjustment base portion 62a, interference between the first attachment portion 61b and the second battery 52 can be prevented. Further, since the space S is formed between the base member 61 and the adjustment base portion 62a, an effect of cooling the engine by the flow of air in the space can be obtained. In particular, a suitable cooling effect can be obtained in a support having an opening described later.
　ベース部材６１は、開口６５を有している。より詳細には、ベース部材６１のベース部６１ａは、ベース部６１ａを貫通する開口６５が形成されている。当該開口６５によって原動部１内の空気の吸入量を増加させ、エンジンの冷却効果を高めることができる。加えて、ベース部材６１に開口６５を形成することにより、ボンネット１２内に空気を吸入するための面積を増加させ、ボンネット１２の正面に位置する吸気部１２Ａから吸入する空気の速度を下げることができる。図１に示すように、ボンネット１２には、作業機の正面側と側面側に跨がって吸気部１２Ａが設けられている。吸気部１２Ａは、網目状の部材によって覆われており、異物の混入を防ぎつつ、空気を吸入するように構成されている。しかし、吸気部１２Ａの空気の吸入速度が速いと、当該吸気部１２Ａの網目の隙間を介してエンジン側（ボンネット内）に異物が流入するおそれがある。ベース部材６１に開口６５を形成することにより、ボンネット１２内へ空気を吸入する部分の面積が大きくなり、吸気部１２Ａにおける空気の吸入速度を低下させることができる。よって、作業機の正面側からの異物の流入を抑制できる。なお、異物の流入を抑制するために、開口６５及び吸気部１２Ａは、網目状の部材によって覆われていることが好ましい。 The base member 61 has an opening 65. More specifically, the base portion 61a of the base member 61 has an opening 65 formed through the base portion 61a. The opening 65 can increase the intake amount of air in the driving unit 1 and enhance the cooling effect of the engine. In addition, by forming the opening 65 in the base member 61, the area for sucking air into the bonnet 12 can be increased, and the speed of the air sucked from the suction portion 12A located in front of the bonnet 12 can be reduced. it can. As shown in FIG. 1, the hood 12 is provided with an air intake portion 12A that straddles the front side and the side surface of the working machine. The intake section 12A is covered with a mesh-like member, and is configured to suck air while preventing foreign substances from being mixed. However, when the air intake speed of the intake section 12A is high, foreign substances may flow into the engine side (in the hood) through the mesh gap of the intake section 12A. By forming the opening 65 in the base member 61, the area of the portion that sucks air into the bonnet 12 increases, and the air suction speed in the suction portion 12A can be reduced. Therefore, the inflow of foreign matter from the front side of the working machine can be suppressed. In addition, in order to suppress the inflow of foreign matter, the opening 65 and the suction portion 12A are preferably covered with a mesh-shaped member.
　開口６５は、空間Ｓに繋がる第１開口６５ａを有する。第１開口６５ａは、ベース部６１ａの左右方向の中央に配置されている。第１開口６５ａは、平面視にて横長の矩形状である。第１開口６５ａが空間Ｓに繋がっているため、ベース部材６１と調整ベース部６２ａとの間に空間Ｓにおける空気の流れによるエンジン８の冷却効果をより高めることができる。 The opening 65 has a first opening 65a connected to the space S. The first opening 65a is arranged at the center in the left-right direction of the base 61a. The first opening 65a has a horizontally long rectangular shape in plan view. Since the first opening 65a is connected to the space S, the cooling effect of the engine 8 by the flow of air in the space S between the base member 61 and the adjustment base portion 62a can be further enhanced.
　また、開口６５は、平面視にて第１バッテリ５１及び調整部材６２に重ならない領域に設けられた第２開口６５ｂを有する。第２開口６５ｂが第１バッテリ５１及び調整部材６２に重ならない領域に設けられているため、第１バッテリ５１及び第２バッテリ５２の搭載態様に影響されず、いずれの場合であっても、空気の吸入効果を得ることができる。よって、エンジンの冷却効果をより高めることができる。第２開口６５ｂは、バッテリの左右両側であって、ラジエータ１０の前方に配置されている。第２開口６５ｂは、平面視にて縦長の矩形状である。ラジエータ１０の前方に開口６５を設けることにより、ラジエータの空気の吸入量を増加させ、エンジン８の冷却効果をより高めることができる。 The opening 65 has a second opening 65b provided in a region that does not overlap the first battery 51 and the adjustment member 62 in plan view. Since the second opening 65b is provided in a region that does not overlap with the first battery 51 and the adjustment member 62, the mounting state of the first battery 51 and the second battery 52 is not affected. Inhalation effect can be obtained. Therefore, the cooling effect of the engine can be further enhanced. The second openings 65b are arranged on both left and right sides of the battery and in front of the radiator 10. The second opening 65b has a vertically long rectangular shape in plan view. By providing the opening 65 in front of the radiator 10, the amount of air intake from the radiator can be increased, and the cooling effect of the engine 8 can be further enhanced.
