従来、電気、エンジン燃料などを移送対象とする移送部材は、損傷されないように外部に露出しない状態で備えられるので、移送部材の点検、交換などのメンテンス作業を行う際、移送部材を取り扱い易いように露出させるのに手間が掛かり、メンテナンス作業に掛かる時間が長くなっている。 Conventionally, transfer members for transferring electricity, engine fuel, etc. are installed in a state where they are not exposed to the outside to prevent damage. Therefore, when performing maintenance work such as inspection or replacement of the transfer members, it is time-consuming to expose the transfer members so that they are easy to handle, which increases the time required for maintenance work.

本発明は、通常時において移送部材を損傷しないように保護できながら、移送部材のメンテナンス作業を能率よく行うことができる収穫機を提供する。 The present invention provides a harvester that can protect the transport member from damage under normal conditions while efficiently performing maintenance work on the transport member.

本発明による収穫機は、
収穫部によって収穫された作物の脱穀処理を行う脱穀装置と、前記脱穀装置の横側方において機体上下方向に沿う方向の縦軸芯を揺動支点にして機体フレームの上方に位置する作業用の閉じ位置と前記機体フレームの横外側に張り出すメンテナンス用の開き位置とに亘って揺動可能に支持され、前記脱穀装置によって得られた穀粒を貯留する穀粒タンクと、前記機体フレームのうち、前記穀粒タンクが前記閉じ位置の際に前記穀粒タンクによって上方から覆われ、かつ、前記穀粒タンクが前記開き位置の際に平面視において露出する部分に設けられ、異なる移送対象の移送を行う複数の移送部材と、が備えられ、前記複数の移送部材を移送対象別に離間させて位置保持する位置保持部材が備えられており、複数の前記位置保持部材が機体前後方向に沿って延び、かつ、機体横幅方向において間隔を空けて並ぶ状態で前記機体フレームに載置支持され、隣合う前記位置保持部材に対して機体前後方向一方側に位置する部位に、バルブユニットが設けられ、前記隣合う前記位置保持部材は、前記バルブユニット側の端部における間隔が前記バルブユニット側とは反対側の端部における間隔よりも広い状態で機体横幅方向に並んでいる。 The harvester according to the present invention comprises:
a grain tank that is supported rotatably on the lateral side of the threshing device between a closed position for work located above the machine frame and an open position for maintenance that protrudes outwardly to the lateral side of the machine frame, the closed position being covered from above by the grain tank when the grain tank is in the closed position and is provided in a portion of the machine frame that is exposed in a plan view when the grain tank is in the open position, and that stores grains obtained by the threshing device; and a position retaining member that separates and retains the position of the plurality of transfer members according to the object to be transferred, the plurality of position retaining members extending along the fore-and-aft direction of the aircraft and are mounted and supported on the aircraft frame in a state of being lined up at intervals in the width direction of the aircraft, a valve unit is provided at a portion located on one side of the fore-and-aft direction of the aircraft with respect to an adjacent position retaining member, and the adjacent position retaining members are lined up in the width direction of the aircraft with the spacing at the end on the valve unit side being wider than the spacing at the end on the opposite side to the valve unit side .

本構成によると、穀粒タンクを閉じ位置にすると、穀粒タンクが移送部材の上方に位置して移送部材をカバーするので、さらに、複数の移送部材が移送対象別に離間する状態で位置保持されて移送対象が異なる移送部材の接触を防止できるので、作業時などの通常時は、移送部材を損傷しないように保護できる。
バルブユニットが位置する側において、バルブユニットの設置、あるいは、移送部材の配置を行い易いように、位置保持部材の機体横幅方向での間隔を広くし、バルブユニットが位置する側とは反対側において、機体横幅方向に沿って並ぶ位置保持部材に亘って足が乗り易いように、位置保持部材の機体横幅方向での間隔を狭くするので、バルブユニットを設置し易く、あるいは、移送部材を配置し易くしながら、移送部材が踏み付けられて損傷あるいは破損されることを防止し易い。 According to this configuration, when the grain tank is in the closed position, the grain tank is positioned above the transfer members and covers the transfer members.Furthermore, the multiple transfer members are held in position at a distance according to the objects to be transferred, preventing contact between transfer members for different objects to be transferred.Therefore, the transfer members can be protected from damage during normal operations such as when working.
On the side where the valve unit is located, the spacing between the position retaining members in the width direction of the aircraft is widened to make it easier to install the valve unit or position the transport members, and on the opposite side to the side where the valve unit is located, the spacing between the position retaining members in the width direction of the aircraft is narrowed to make it easier to place a foot across the position retaining members lined up along the width direction of the aircraft.This makes it easier to install the valve unit or position the transport members while also preventing the transport members from being stepped on and damaged or broken.

穀粒タンクを開き位置にする位置変更するだけで穀粒タンクが機体フレームの横外側に張り出して移送部材の上方が開放されて移送部材を取り扱い易いので、さらに、複数の移送部材は、移送対象別に離間した状態で位置保持されてメンテナンス対象の移送部材を複数の移送部材から選り抜き易いので、移送部材のメンテンナス作業を能率よく行うことができる。
本発明においては、
前記バルブユニットは、前記機体フレームに備えられたバルブユニット支持台に支持され、前記隣合う前記位置保持部材における前記バルブユニット側の端部が前記バルブユニット支持台に支持されていると好適である。 By simply changing the position of the grain tank to the open position, the grain tank protrudes outward from the side of the body frame, opening up the top of the transport members, making it easy to handle the transport members.Furthermore, the multiple transport members are held in position spaced apart according to the transport object, making it easy to select the transport member to be maintained from the multiple transport members, so maintenance work on the transport members can be carried out efficiently.
In the present invention,
It is preferable that the valve unit is supported by a valve unit support base provided on the aircraft frame, and that end portions of the adjacent position retaining members on the valve unit side are supported by the valve unit support base.

本発明においては、
前記位置保持部材の両横側部に、前記移送部材を支持する支持部が備えられていると好適である。 In the present invention,
It is preferable that the position retaining member is provided on both lateral sides with support portions for supporting the transport member.

本構成によると、位置保持部材の両横側部に移送部材が支持部によって支持されるので、複数の移送部材が一つの位置保持部材によって離間する状態にしっかり位置保持され、移送部材の接触し合いを効果的に防止できる。 With this configuration, the transfer members are supported by the support parts on both lateral sides of the position-retaining member, so that multiple transfer members are firmly held in position by a single position-retaining member in a spaced-apart state, effectively preventing the transfer members from coming into contact with each other.

本発明においては、
前記位置保持部材の両横側部において、前記位置保持部材の長手方向での複数箇所に前記移送部材を支持する支持部が備えられていると好適である。 In the present invention,
It is preferable that the position retaining member is provided with support portions for supporting the transport member at a plurality of positions in the longitudinal direction of the position retaining member on both lateral sides thereof.

本構成によると、位置保持部材の長手方向での複数箇所において移送部材が支持部によって位置保持部材に支持されるので、移送部材が位置保持部材にしっかり支持されて動き難くなり、移送部材どうしの触れ合いを効果的に防止することができる。 With this configuration, the transfer member is supported by the support parts at multiple points in the longitudinal direction of the position retaining member, so the transfer member is firmly supported by the position retaining member and is less likely to move, effectively preventing the transfer members from coming into contact with each other.

本発明においては、
複数の前記位置保持部材が機体前後方向に沿って延び、かつ、機体横幅方向において間隔を空けて並ぶ状態で前記機体フレームに載置支持され、隣合う前記位置保持部材の間の空間に前記移送部材が落とし込まれていると好適である。 In the present invention,
It is preferable that the multiple position retaining members extend along the fore-and-aft direction of the aircraft and are supported on the aircraft frame in a state where they are spaced apart in the width direction of the aircraft, and that the transport member is dropped into the space between adjacent position retaining members.

本構成によると、作業者が穀粒タンクを開き位置にして機体フレームに乗り上がる際、機体横外側から乗り上がるのが通常であって、機体横幅方向において間隔を空けて並ぶ位置保持部材に亘って足が乗せられ易いので、移送部材が踏まれて損傷あるいは破損されることを防止し易い。 With this configuration, when an operator places the grain tank in the open position and climbs onto the machine frame, he or she usually climbs onto the outer side of the machine, which makes it easy for the operator to place their feet across the position retaining members that are spaced apart across the width of the machine, making it easier to prevent the transfer members from being stepped on and damaged or broken.

本発明においては、
前記移送部材は、機体側面視において前記位置保持部材の上端よりも下方に位置する状態で前記空間に落とし込まれていると好適である。 In the present invention,
It is preferable that the transfer member is dropped into the space in a state where it is positioned below an upper end of the position retaining member when viewed from the side of the aircraft.

本構成によると、位置保持部材に足が載せられても、履物が移送部材に当り難いので、移送部材が踏まれることを効果的に防止することができる。 With this configuration, even if a foot is placed on the position retaining member, the footwear is unlikely to hit the transport member, effectively preventing the transport member from being stepped on.

本発明においては、
前記移送部材は、機体側面視において前記位置保持部材と重複する状態で前記空間に落とし込まれていると好適である。 In the present invention,
It is preferable that the transfer member is dropped into the space so as to overlap with the position maintaining member in a side view of the aircraft body.

本発明においては、
前記複数の前記移送部材に、電気を移送対象とする電線、エンジン燃料を移送対象とする燃料ホース、および、圧油を移送対象とする油圧ホースが備えられ、前記電線、前記燃料ホースおよび前記油圧ホースのうちのいずれか一つが前記空間に落とし込まれ、前記電線、前記燃料ホースおよび前記油圧ホースのうち、前記空間に落とし込まれたものを除く二つが前記空間の両横外側に振り分けて設けられていると好適である。 In the present invention,
It is preferable that the plurality of transfer members are provided with electric wires for transferring electricity, a fuel hose for transferring engine fuel, and a hydraulic hose for transferring pressurized oil, and that one of the electric wires, the fuel hose and the hydraulic hose is dropped into the space, and that the other two of the electric wires, the fuel hose and the hydraulic hose other than the one dropped into the space are distributed to the outside on both sides of the space.

本構成によると、電線、油圧ホースおよび燃料ホースを移送対象別に位置保持部材によって離間させることができるので、電線と油圧ホースの触れ合い、あるいは、電線と燃料ホースの触れ合い、あるいは、油圧ホースと燃料ホースの触れ合いを防止することができる。 With this configuration, the electric wires, hydraulic hoses, and fuel hoses can be separated by the position-retaining members according to the object being transported, preventing contact between the electric wires and hydraulic hoses, or between the electric wires and fuel hoses, or between the hydraulic hoses and fuel hoses.

本発明においては、
前記複数の前記移送部材に、電気を移送対象とする電線、および、エンジン燃料を移送対象とする燃料ホースが備えられ、前記電線および前記燃料ホースの一方が前記空間に落とし込まれ、前記電線および前記燃料ホースの他方が前記空間の横外側に設けられていると好適である。 In the present invention,
It is preferable that the multiple transfer members are provided with an electric wire for transferring electricity and a fuel hose for transferring engine fuel, one of the electric wire and the fuel hose being dropped into the space and the other of the electric wire and the fuel hose being provided on the outside of the space.

本構成によると、位置保持部材が電線と燃料ホースとの間に位置する隔壁部材になるので、電線とエンジン燃料ホースが触れ合うことを効果的に防止できる。 With this configuration, the position retaining member is a partition member located between the electric wire and the fuel hose, effectively preventing the electric wire and the engine fuel hose from coming into contact with each other.

本発明においては、
前記複数の前記移送部材に、電気を移送対象とする電線、圧油を移送対象とする第１油圧ホース、前記第１油圧ホースよりも高圧の圧油を移送対象とする第２油圧ホースが備えられ、前記電線が前記空間に落とし込まれると共に前記位置保持部材に支持され、前記第２油圧ホースが前記空間の横外側に設けられていると好適である。 In the present invention,
It is preferable that the multiple transfer members are provided with electric wires for transferring electricity, a first hydraulic hose for transferring pressurized oil, and a second hydraulic hose for transferring pressurized oil having a higher pressure than the first hydraulic hose, the electric wires being dropped into the space and supported by the position maintaining member, and the second hydraulic hose being provided on the outside of the space to the side.

本構成によると、位置保持部材が電線と第２油圧ホースとの間に位置する隔壁部材になり、かつ、電線が位置保持部材に支持されるので、第２油圧ホースが高圧の圧油の流動によって振れ動くことがあっても、電線と第２油圧ホースとが触れ合うことを防止できる。 With this configuration, the position-retaining member serves as a bulkhead member located between the electric wire and the second hydraulic hose, and the electric wire is supported by the position-retaining member, so that even if the second hydraulic hose is caused to swing by the flow of high-pressure oil, the electric wire and the second hydraulic hose can be prevented from coming into contact with each other.

本発明においては、
前記複数の前記移送部材に、電気を移送対象とする電線、圧油を移送対象とする第１油圧ホース、前記第１油圧ホースよりも高圧の圧油を移送対象とする第２油圧ホース、および、エンジン燃料を移送対象とする燃料ホースが備えられ、前記電線が前記空間に落とし込まれると共に前記位置保持部材に支持され、前記第２油圧ホースが前記空間の両横外側のうちの一方の横外側に設けられ、前記燃料ホースが前記空間の両横外側のうちの他方の横外側に設けられていると好適である。 In the present invention,
It is preferable that the multiple transfer members are provided with an electric wire for transferring electricity, a first hydraulic hose for transferring pressurized oil, a second hydraulic hose for transferring pressurized oil having a higher pressure than the first hydraulic hose, and a fuel hose for transferring engine fuel, the electric wires being dropped into the space and supported by the position maintaining member, the second hydraulic hose being provided on one of the two lateral outer sides of the space, and the fuel hose being provided on the other of the two lateral outer sides of the space.

本構成によると、位置保持部材が電線と第２油圧ホースとの間に位置する隔壁部材になり、位置保持部材が電線と燃料ホースとの間に位置する隔壁部材になり、電線が位置保持部材に支持されるので、第２油圧ホースが高圧の圧油の流動によって振れ動くことがあっても、燃料ホースが走行振動によって振れ動くことがあっても、電線と第２油圧ホースとが触れ合うこと、電線と燃料ホースとが触れ合うことを防止できる。 According to this configuration, the position-retaining member is a partition member located between the electric wire and the second hydraulic hose, the position-retaining member is a partition member located between the electric wire and the fuel hose, and the electric wire is supported by the position-retaining member. Therefore, even if the second hydraulic hose vibrates due to the flow of high-pressure oil or the fuel hose vibrates due to running vibrations, the electric wire and the second hydraulic hose and the electric wire and the fuel hose can be prevented from coming into contact with each other.

本発明においては、
前記位置保持部材の縦断面形状が山形であると好適である。 In the present invention,
It is preferable that the position-retaining member has a mountain-shaped cross section.

本構成によると、位置保持部材のうちの移送部材を支持する横側部が上向きになるので、移送部材を位置保持部材に支持させる作業、位置保持部材に対する移送部材の支持を解除する作業を行い易く、移送部材のメンテナンス作業を能率よく行える。 With this configuration, the lateral side of the position retaining member that supports the transport member faces upward, making it easier to support the transport member on the position retaining member and to release the support of the transport member from the position retaining member, and allowing efficient maintenance of the transport member.
