[0003] [Patent Document 1] JP 2014-97052 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, transfer members for transferring electricity, engine fuel, etc. are provided 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.

[0005] The present invention provides a harvester that can protect a transport member from damage under normal conditions and can efficiently perform maintenance work on the transport member. [Means for solving the problem]

[0006] The harvester according to the present invention comprises: The present invention is provided with a threshing device that threshes crops harvested by a harvesting section, a grain tank that is supported on the lateral side of the threshing device so as to be swingable 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, with a vertical axis in the vertical direction of the machine body as a swing fulcrum, and that stores grains obtained by the threshing device, and a plurality of transport members that are provided in a portion of the machine frame that is covered from above by the grain tank when the grain tank is in the closed position and is exposed in a plan view when the grain tank is in the open position, and that transport different transport objects, and a position holding member that holds the positions of the plurality of transport members by separating them according to the transport objects is provided. a plurality of the position retaining members extend along the longitudinal direction of the aircraft body, and are mounted and supported on the aircraft frame in a state in which they are arranged at intervals in the lateral direction of the aircraft body; a valve unit is provided at a portion located on one side of the longitudinal direction of the aircraft body with respect to adjacent position retaining members; and the adjacent position retaining members are arranged in the lateral direction of the aircraft body with the interval at the end on the valve unit side being wider than the interval at the end on the opposite side to the valve unit side. .

[0007] 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.

[0008] 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.

[0009] 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.

[0010] According to this configuration, the transport members are supported by support portions on both lateral sides of the position retaining member, so that multiple transport members are firmly held in position and spaced apart by a single position retaining member, effectively preventing the transport members from coming into contact with each other.

[0011] 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.

[0012] According to this configuration, the transport member is supported on the position retaining member by the support portions at multiple points in the longitudinal direction of the position retaining member, so that the transport member is firmly supported on the position retaining member and is less likely to move, effectively preventing the transport members from coming into contact with each other.

[0013] 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.

[0014] 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 up from the outside side of the machine, which makes it easy for the operator to place their feet across the position retaining members that are spaced apart in the width direction of the machine, making it easy to prevent the transfer members from being stepped on and damaged or broken.

[0015] 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.

[0016] According to this configuration, even if a foot is placed on the position maintaining member, the footwear is unlikely to hit the transporting member, so that the transporting member can be effectively prevented from being stepped on.

[0017] 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.

[0018] According to this configuration, even if a foot is placed on the position maintaining member, the footwear is unlikely to hit the transporting member, so that the transporting member can be effectively prevented from being stepped on.

[0019]

[0020]

[0021] 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.

[0022] According to this configuration, the electric wires, hydraulic hoses, and fuel hoses can be separated by the position maintaining members according to the object to be transported, thereby preventing the electric wires and hydraulic hoses from coming into contact with each other, or the electric wires and fuel hoses, or the hydraulic hoses and fuel hoses from coming into contact with each other.

[0023] 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.

[0024] According to this configuration, the position retaining member serves as a partition member located between the electric wire and the fuel hose, so that the electric wire and the engine fuel hose can be effectively prevented from coming into contact with each other.

[0025] 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 retaining member, and the second hydraulic hose being provided on the outside of the space to the side.

[0026] According to this configuration, the position maintaining member becomes a partition member located between the electric wire and the second hydraulic hose, and the electric wire is supported by the position maintaining member, so that even if the second hydraulic hose is caused to swing due to the flow of high-pressure oil, the electric wire and the second hydraulic hose can be prevented from coming into contact with each other.

[0027] 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.

[0028] According to this configuration, the position maintaining member becomes a partition member located between the electric wire and the second hydraulic hose, the position maintaining member becomes a partition member located between the electric wire and the fuel hose, and the electric wire is supported by the position maintaining member. Therefore, even if the second hydraulic hose vibrates due to the flow of high-pressure oil and even if the fuel hose vibrates due to traveling vibrations, it is possible to prevent the electric wire and the second hydraulic hose and the electric wire and the fuel hose from coming into contact with each other.

[0029] In the present invention, It is preferable that the position-retaining member has a mountain-shaped cross section.

[0030] According to this configuration, the lateral side portion 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 maintenance work on the transport member can be performed efficiently.
