[0005] Patent Document 1: Japanese Patent Application Publication No. 2014-97052 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the past, transfer components that transport objects such as electricity and engine fuel were not exposed to the outside to avoid damage. Therefore, when performing maintenance work such as inspection and replacement of transfer components, it takes effort to expose the transfer components in order to make them easier to handle, which increases the time spent on maintenance work.

[0008] The present invention provides a harvester that can protect the conveying components from damage under normal circumstances and can efficiently perform maintenance work on the conveying components.

[0009] Solution for solving the problem

[0010] The harvester of the present invention includes: a threshing device for threshing crops harvested by a harvesting section; a grain bin supported laterally by the threshing device, capable of swinging between a closed working position located above the machine frame and an open maintenance position extending laterally outward from the machine frame, with a longitudinal axis as the pivot point along the vertical direction of the machine body, and storing grains obtained by the threshing device; and a plurality of transfer members disposed in the machine frame, which are covered from above by the grain bin when the grain bin is in the closed position and exposed when the grain bin is in the open position in a top view, for transferring different transfer objects, and the harvester includes a position holding member that holds the plurality of transfer members in position separately according to the transfer objects.

[0011] According to this structure, since the grain bin is positioned above and covers the transfer component when it is in the closed position, and since the multiple transfer components are positioned separately according to the transfer objects, contact between transfer components with different transfer objects can be prevented. Therefore, the transfer components can be protected from damage during operation and other normal times.

[0012] Since the grain bin extends laterally outward from the machine frame simply by changing its position to the open position, and the top of the transfer component is open, the transfer component is easy to handle. Furthermore, since multiple transfer components are positioned separately according to the transfer object, it is easy to select the transfer component that needs maintenance from among the multiple transfer components. Therefore, maintenance work on the transfer components can be performed efficiently.

[0013] In this invention, it is preferable that the two lateral sides of the position holding member have support portions for supporting the transfer member.

[0014] According to this structure, the transfer component is supported by the support portion on the two lateral sides of the position holding component. Therefore, multiple transfer components are firmly held in a separate state by a position holding component, which can effectively prevent the transfer components from contacting each other.

[0015] In this invention, it is preferable that the position holding member has support portions for supporting the transfer member at multiple locations on both lateral sides and along the length of the position holding member.

[0016] According to this structure, at multiple locations along the length of the position holding member, the transfer member is supported by the support portion on the position holding member. Therefore, the transfer member is firmly supported by the position holding member and is difficult to move, effectively preventing the transfer members from contacting each other.

[0017] In this invention, preferably, a plurality of the position holding components are mounted and supported on the body frame in a state in which they extend along the front-rear direction of the body and are spaced apart in the transverse direction of the body, and the transfer component falls into the space between adjacent position holding components.

[0018] According to this structure, when the operator puts the grain bin in the open position and climbs onto the machine frame, he usually climbs from the outside of the machine body. His feet can easily step over the position holding parts that are arranged at intervals in the width of the machine body. Therefore, it is easy to prevent the transfer parts from being stepped on and damaged or broken.

[0019] In this invention, it is preferred that the transfer component falls into the space in a position lower than the upper end of the position holding component when viewed from the side of the machine body.

[0020] According to this structure, even if the foot is placed on the position holding component, the shoe is unlikely to touch the transfer component, thus effectively preventing the transfer component from being stepped on.

[0021] In this invention, it is preferred that the transfer component falls into the space in a state of overlapping with the position holding component when viewed from the side of the machine body.

[0022] According to this structure, even if the foot is placed on the position holding component, the shoe is unlikely to touch the transfer component, thus effectively preventing the transfer component from being stepped on.

[0023] In this invention, preferably, a valve unit is provided at a position on the front-rear direction side of the body relative to the adjacent position holding member, and the adjacent position holding members are arranged along the transverse width direction of the body such that the interval between the ends on the valve unit side is wider than the interval between the ends on the opposite side of the valve unit side.

[0024] On the side where the valve unit is located, the spacing of the position holding component in the horizontal width direction of the body is widened to facilitate the installation of the valve unit or the configuration of the transfer component. On the opposite side of the valve unit, the spacing of the position holding component in the horizontal width direction of the body is narrowed to facilitate stepping over the position holding component arranged along the horizontal width direction of the body. Therefore, it is easy to install the valve unit or configure the transfer component, and it is easy to prevent the transfer component from being stepped on and damaged or broken.

[0025] In this invention, preferably, the plurality of transfer components include an electrical wire for transferring electricity, a fuel hose for transferring engine fuel, and a hydraulic hose for transferring pressurized oil. Any one of the electrical wire, the fuel hose, and the hydraulic hose falls into the space, and the other two of the electrical wire, the fuel hose, and the hydraulic hose, besides falling into the space, are separately arranged on two lateral outer sides of the space.

[0026] According to this structure, since the position holding component can separate the wires, hydraulic hoses and fuel hoses according to the objects being transferred, it is possible to prevent the wires from coming into contact with the hydraulic hoses, or the wires from coming into contact with the fuel hoses, or the hydraulic hoses from coming into contact with the fuel hoses.

[0027] In this invention, preferably, the plurality of transfer components include an electrical wire for transferring electricity and a fuel hose for transferring engine fuel, one of the electrical wire and the fuel hose falling into the space, and the other of the electrical wire and the fuel hose being disposed laterally outside the space.

[0028] According to this structure, the position holding component becomes a partition component located between the wire and the fuel hose, thus effectively preventing the wire and the engine fuel hose from coming into contact with each other.

[0029] In this invention, preferably, the plurality of transfer components include an electrical wire for transferring electricity, a first hydraulic hose for transferring pressurized oil, and a second hydraulic hose for transferring pressurized oil at a higher pressure than the first hydraulic hose. The electrical wire falls into the space and is supported by the position holding component, and the second hydraulic hose is disposed on the lateral outer side of the space.

[0030] According to this structure, the position holding member becomes a partition member located between the wire and the second hydraulic hose, and the wire is supported by the position holding member. Therefore, even if the second hydraulic hose swings due to the flow of high-pressure oil, it is possible to prevent the wire and the second hydraulic hose from coming into contact with each other.

[0031] In this invention, preferably, the plurality of transfer components include an electrical wire for transferring electricity, a first hydraulic hose for transferring pressurized oil, a second hydraulic hose for transferring pressurized oil at a higher pressure than the first hydraulic hose, and a fuel hose for transferring engine fuel. The electrical wire falls into the space and is supported by the position holding component. The second hydraulic hose is located on the outer side of one of the two outer sides of the space, and the fuel hose is located on the outer side of the other of the two outer sides of the space.

[0032] According to this structure, the position holding member becomes a partition member located between the wire and the second hydraulic hose, and the position holding member becomes a partition member located between the wire and the fuel hose. The wire is supported by the position holding member. Therefore, whether the second hydraulic hose swings due to the flow of high-pressure oil or the fuel hose swings due to driving vibration, it can prevent the wire and the second hydraulic hose from contacting each other, and the wire and the fuel hose from contacting each other.

[0033] In this invention, it is preferred that the longitudinal cross-sectional shape of the position holding component is mountain-shaped.

[0034] According to this structure, the lateral side of the support transfer member in the position holding member faces upward. Therefore, it is easy to perform operations such as supporting the transfer member on the position holding member and releasing the support of the transfer member relative to the position holding member, and maintenance operations of the transfer member can be performed efficiently.

[0063] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0064] It should be noted that in the following description, the running gear of a combine harvester (an example of a "harvester") will be... Figure 1 , 2 As shown, arrow F points in the direction of "front of the aircraft," and arrow B points in the direction of "rear of the aircraft." Figure 1 The direction of arrow U is set to "above the body", and the direction of arrow D is set to "below the body". Figure 2 The direction of arrow L is set to "left side of the aircraft", and the direction of arrow R is set to "right side of the aircraft".

[0065] [Regarding the combine harvester as a whole]

[0066] like Figure 1 , 2 As shown, the combine harvester comprises: a body frame 1 constructed by connecting multiple steel components such as square tubing; and a traveling body 3 having a pair of left and right tracked traveling devices 2 located at the lower part of the body frame 1. A driver's section 4 and a harvesting conveyor 5 are located at the front of the traveling body 3, and a power unit 7 with an engine 6 is formed at the lower part of the driver's section 4. The driver's section 4 has a cab 4a covering the passenger space. The harvesting conveyor 5 includes: a harvesting section 5b located at the front of the harvesting conveyor 5, which harvests rice and wheat (crops planted in the field) by using a push-shear type harvesting device 5a; and a supply conveyor 5c located at the rear of the harvesting conveyor 5, which transports the harvested stalks harvested by the harvesting section 5b to a designated location on the traveling body 3. At the rear of the traveling body 3, a threshing device 8 and a grain bin 9 are arranged laterally. In the threshing device 8, the root of the harvested rice stalks, conveyed by the supply conveyor 5c, is received by the threshing supply chain 8a and conveyed toward the rear of the threshing device 8. The tips of the conveyed harvested rice stalks are inserted into the threshing chamber (not shown) and threshed by a rotating threshing drum (not shown). A sorting process is performed to separate the grains and dust such as straw fragments obtained through the threshing process. The grain bin 9 stores the grains obtained from the threshing device 8. A grain discharge device 10 is connected to the rear of the grain bin 9 to discharge the grains from the grain bin 9.

[0067] [Regarding the grain discharge device]

[0068] like Figure 1 , 2 As shown, the grain discharge device 10 includes a longitudinal conveying section 11 positioned rearward of the grain bin 9 in a vertical orientation along the machine body, and a transverse conveying section 12 extending from the upper part of the longitudinal conveying section 11. The lower part of the longitudinal conveying section 11 is connected to the lower rear part of the grain bin 9 via a connecting box 13. Grains discharged from the grain bin 9 are fed into the longitudinal conveying section 11 through the connecting box 13. Both the longitudinal conveying section 11 and the transverse conveying section 12 are constructed using screw conveyors.

[0069] [Regarding grain bins]

[0070] like Figure 1 , 2 As shown, the grain bin 9 is positioned laterally to the side of the threshing device 8. A connecting box 13, which connects the lower rear part of the grain bin 9 to the longitudinal conveying section 11 of the grain discharge device 10, is supported on the machine frame 1 in a state where it can rotate around a longitudinal axis P, which is the same as the spiral axis of the longitudinal conveying section 11 along the vertical direction of the machine body. The grain bin 9 is supported on the machine frame 1 via the connecting box 13, and is configured to be able to swing around the longitudinal axis P as a pivot point in a closed position located above the machine frame 1 for operation. Figure 2 The position indicated by the double-dotted line) and the maintenance opening position extending laterally outward from the body frame 1 ( Figure 2 It swings between the positions indicated by the solid line in the middle.

[0071] [Regarding the transfer components and position holding components]

[0072] like Figure 2 , 3 As shown, in the body frame 1, the portion 1a that is covered from above by the grain bin 9 when it is in the closed position and exposed when viewed from above when the grain bin 9 is in the open position is equipped with multiple transfer components 14, 15, 16, and 20, each carrying a different object. The multiple transfer components 14, 15, 16, and 20 are configured to be held in position according to the objects being transferred by a position holding component 17, preventing the transfer components 14, 15, 16, and 20 carrying different objects from swinging and contacting each other due to vibration of the body or the transfer of the objects.

[0073] Specifically, such as Figure 3 , 4As shown in Figure 5, two position holding members 17 are mounted and supported on a portion 1a of the body frame 1, extending along the longitudinal direction of the body. The two position holding members 17 are arranged at intervals in the transverse direction of the body, forming a space S between adjacent members 17. The support of the position holding members 17 to the portion 1a is achieved by welding the front portion of the position holding member 17 to the frame member 1b constituting the body frame 1 and welding the rear portion of the position holding member 17 to the valve unit support platform 1c provided on the body frame 1. Support portions 18 for supporting transfer members 14, 15, 16, and 20 are provided on each of the two transverse sides 17a of the two position holding members 17. Support portions 18 are provided at multiple locations along the longitudinal direction (trailback direction) of the position holding member 17 on each of the two transverse sides 17a of the two position holding members 17. Transfer members 14, 15, 16, and 20 are supported by the support portions 18 on the transverse sides 17a of the position holding members 17. Each support portion 18 is configured to have a belt portion wound around the transfer members 14, 15, 16, and 20, and a locking portion formed on the belt portion, the locking portion being capable of engaging and disengaging into the locking hole 17b provided by the position holding member 17 (see reference). Figure 4 This supports the transfer components 14, 15, 16, and 20 on the position holding component 17.

[0074] In this embodiment, the position holding member 17 is configured to hold the transfer members 14, 15, 16, and 20 separately in the horizontal direction of the machine body. However, it is not limited to this. The position holding member 17 may also be configured to be arranged along the horizontal direction of the machine body, so that the transfer members 14, 15, 16, and 20 are held separately in the front-rear direction of the machine body.

[0075] like Figure 5 As shown, the position holding member 17 is configured with a mountain-shaped longitudinal cross-section. The transverse side 17a of the position holding member 17, which supports the transfer members 14, 15, 16, and 20, faces upwards. In this embodiment, the position holding member 17 is composed of a plate-shaped member bent into a mountain-shaped longitudinal cross-section. Besides the bent plate-shaped member, the position holding member 17 can also be a angular member or a mountain-shaped member without cavities. Furthermore, the position holding member 17 can be a member with a longitudinal cross-section other than a mountain shape, such as a square tube or a round tube. Additionally, the position holding member 17 can be a member composed of a base plate mounted and supported on the body frame 1 and a longitudinal plate erected from the base plate to support the transfer members 14, 15, 16, and 20.

[0076] In this embodiment, multiple transfer components with different transfer targets include: a fuel hose 15 for transferring engine fuel, an electrical wire 14 (wiring harness) for transferring electricity, a first hydraulic hose 20 for transferring pressurized oil, and a second hydraulic hose 16 for transferring pressurized oil at a higher pressure than the pressurized oil transferred by the first hydraulic hose 20. In this embodiment, two fuel hoses 15 are provided, but one or more fuel hoses 15 may also be provided. In this embodiment, three electrical wires 14 are provided, but two or fewer or four or more electrical wires 14 may also be provided. In this embodiment, one first hydraulic hose 20 is provided, but two or more first hydraulic hoses 20 may also be provided. In this embodiment, six second hydraulic hoses 16 are provided, but five or fewer or seven or more second hydraulic hoses 16 may also be provided.

[0077] like Figure 3 , 5 As shown, the wire 14 falls into space S and is supported by the support 18 on one of the two position holding members 17 located on the lateral inner side of the fuselage. The fuel hose 15 is located on the lateral outer side of the fuselage on one of the two lateral outer sides of space S and is supported by the support 18 on one of the two position holding members 17 located on the lateral outer side of the fuselage. The wire 14 and the fuel hose 15 are held separately in the lateral width direction of the fuselage by the two position holding members 17.

[0078] When viewed from the side, the wire 14 is located slightly below the upper end 17t of the position holding member 17, and falls into the space S in a state of overlapping with the position holding member 17. The fuel hose 15 is located slightly below the upper end 17t of the position holding member 17 when viewed from the side, and is positioned laterally outside the space S in a state of overlapping with the position holding member 17.

[0079] In this embodiment, the fuel hose 15 is located on the outer lateral side of the body, one of the two outer lateral sides of the space S. However, it can also be located on the outer lateral side of the body, one of the two outer lateral sides of the space S. In this embodiment, the wire 14 falls into the space S, and the fuel hose 15 is located on the outer lateral side of the space S. However, it is also possible that the wire 14 is located on the outer lateral side of the space S, and the fuel hose 15 falls into the space S.

[0080] like Figure 3 , 5As shown, the wire 14 falls into space S and is supported by the support portion 18 on the position holding member 17 located on the transverse inner side of the body among the two position holding members 17. Three of the six second hydraulic hoses 16a are located on the transverse outer side of the body on the transverse inner side of the two transverse outer sides of space S, and are supported by the support portion 18 on the position holding member 17 located on the transverse inner side of the body among the two position holding members 17. The wire 14 and the three second hydraulic hoses 16a are positioned separately in the transverse width direction of the body by the position holding member 17 located on the transverse inner side of the body among the two position holding members 17. When viewed from the side of the body, the three second hydraulic hoses 16a are located below the upper end 17t of the position holding member 17, and are arranged on the transverse outer side of space S in a state of overlapping with the position holding member 17 when viewed from the side of the body.

[0081] In this embodiment, the second hydraulic hose 16a is located on the outer side of the inner side of the body in the two outer sides of the space S, but it can also be located on the outer side of the outer side of the body in the two outer sides of the space S.

[0082] like Figure 3 , 5 As shown, the wire 14 falls into space S and is supported by the support 18 on the position holding member 17 located on the lateral inner side of the body among the two position holding members 17. Three of the six second hydraulic hoses 16a are located on the lateral outer sides of the body on the lateral inner side of the two lateral outer sides of space S, and are supported by the support 18 on the position holding member 17 located on the lateral inner side of the body among the two position holding members 17. The fuel hose 15 is located on the lateral outer side of the body on the lateral outer side of the two lateral outer sides of space S, and is supported by the support 18 on the position holding member 17 located on the lateral outer side of the body among the two position holding members 17. The wire 14 and the three second hydraulic hoses 16a are held separately in the lateral width direction of the body by the position holding member 17 located on the lateral inner side of the body among the two position holding members 17. The wire 14 and the fuel hose 15 are held separately in the lateral width direction of the body by the two position holding members 17.

[0083] In this embodiment, the second hydraulic hose 16a is located on the outer side of the machine body in one of the two outer sides of the space S, and the fuel hose 15 is located on the outer side of the machine body in one of the two outer sides of the space S. Alternatively, the second hydraulic hose 16a can be located on the outer side of the machine body in one of the two outer sides of the space S, and the fuel hose 15 can be located on the outer side of the machine body in one of the two outer sides of the space S.

[0084] like Figure 3 , 5As shown, the first hydraulic hose 20 is located on the inner side of the machine body, one of the two outer sides of the space S, and is supported by the support 18 on the inner side of the machine body position holding member 17 of the two position holding members 17. The first hydraulic hose 20 and the wire 14 are positioned separately in the machine body width direction by the inner side of the machine body position holding member 17 of the two position holding members 17. The other three second hydraulic hoses 16b of the six second hydraulic hoses 16 fall into the space S and are supported by the support 18 on the outer side of the machine body position holding member 17 of the two position holding members 17. The wire 14 and the second hydraulic hoses 16b are both located in the space S, but are positioned separately in the machine body width direction by the support provided by the two position holding members 17 and the width of the gap between the wire 14 and the second hydraulic hoses 16b.

[0085] like Figure 5 As shown, the power cable 14 and the second hydraulic hose 16b fall into space S, located slightly below the upper end 17t of the position holding member 17, and overlap with the position holding member 17 when viewed from the side. The first hydraulic hose 20, the second hydraulic hose 16a, and the fuel hose 15, located on the lateral outer side of space S, are positioned slightly below the upper end 17t of the position holding member 17, and overlap with the position holding member 17 when viewed from the side. When climbing onto part 1a of the machine frame 1, the operator's feet step over the two position holding members 17, preventing the transfer components (power cable 14, first hydraulic hose 20, second hydraulic hoses 16a, 16b, fuel hose 15) from being stepped on by shoes.

[0086] like Figure 3 , 4 As shown, a valve unit 19 is provided at a location on the rear side of the machine body relative to the adjacent position holding member 17. The distance K1 (the distance between the upper ends 17t of the adjacent position holding members 17) between the valve unit sides is wider than the distance K2 (the distance between the upper ends 17t of the adjacent position holding members 17 on the opposite side from the valve unit side). On the side where the valve unit 19 is located, it is easy to install the valve unit 19 or to arrange the transfer components (electrical wire 14, fuel hose 15, second hydraulic hoses 16a, 16b, and first hydraulic hose 20), and on the side opposite to the side where the valve unit 19 is located, it is easy to step over the two position holding members 17. In this embodiment, the valve unit 19 is provided at a location on the rear side of the machine body relative to the adjacent position holding member 17, but it is also possible to provide the valve unit 19 at a location on the front side of the machine body relative to the adjacent position holding member 17.

[0087] like Figure 5As shown, in this embodiment, a first hydraulic hose 20 is provided. This first hydraulic hose 20 is equipped with a drain port (not shown) connecting the valve unit 19 to the working oil tank 23 (see reference 23). Figure 2 , 6 The hydraulic hose that is connected can be, but is not limited to, a hydraulic hose that can transfer any pressurized oil.

[0088] like Figure 5 As shown, in this embodiment, three second hydraulic hoses 16a are provided. The three second hydraulic hoses 16a and one first hydraulic hose 20 are bundled together by the support portion 18 and supported on the position holding member 17. As one of the three second hydraulic hoses 16a, a hose is provided that receives power from the hydraulic pump 22 (see reference 20). Figure 6 The hydraulic hose that supplies pressurized oil to the valve unit 19 is one of the other two of the three second hydraulic hoses 16a. It is provided with a hydraulic hose that supplies pressurized oil from the valve unit 19 to a hydraulic cylinder (not shown) that performs lifting and lowering operations on the machine frame 1 relative to the track frame (not shown) of the tracked travel device 2 on the left side. However, it is not limited to this and can also be a hydraulic hose that supplies pressurized oil to any actuator or other object.

[0089] like Figure 5 As shown, in this embodiment, three second hydraulic hoses 16b are provided. The three second hydraulic hoses 16b are bundled together by the support portion 18 and supported on the position holding member 17. One of the three second hydraulic hoses 16b is provided with a hydraulic hose that supplies pressurized oil from the valve unit 19 to a hydraulic cylinder (not shown) that performs lifting and lowering operations on the harvesting conveyor 5. The other two second hydraulic hoses 16b are provided with hydraulic hoses that supply pressurized oil from the valve unit 19 to a hydraulic cylinder (not shown) that performs lifting and lowering operations on the machine frame 1 relative to the track frame (not shown) of the tracked travel device 2 on the right side. However, this is not a limitation, and the hoses may also supply pressurized oil to any actuator.

[0090] like Figure 5As shown, multiple wires 14 are provided. In this embodiment, three wires 14 are provided, but two or fewer, or four or more wires may also be provided. The three wires 14 pass through a flexible protective tube 32 to form a bundle, and are supported on the position holding member 17 via the protective tube 32 and the support portion 18. In this embodiment, the three wires 14 include a wire that supplies an electrical signal as a valve operation command to the valve unit 19, but it is not limited to this. Wires that supply power to the rotary motor (not shown) for driving the grain discharge device 10 may also be provided. In addition, wires that supply electrical signals to any device to be operated and wires that supply power for driving any actuator may also be provided. Furthermore, the power to be transferred may be both electrical signals and power, or only either electrical signals or power.

[0091] like Figure 5 As shown, in this embodiment, two fuel hoses 15 are provided. One of the two fuel hoses 15 extends from the fuel tank 33 located at the rear of the vehicle body 3 (see reference 33). Figure 2 The engine fuel is supplied to the engine 6. The other fuel hose 15 of the two fuel hoses 15 returns the engine fuel from the engine 6 to the fuel tank 33.

[0092] like Figure 1 , 2 As shown, the power unit 7 includes an oil cooler 25 located laterally outward of the engine block than the engine radiator 24, and which cools the working oil.
