Modes for Carrying Out the Invention

[0014] [First Embodiment] A first embodiment of the present invention will now be described. First, the overall configuration of the combine harvester 1 according to this embodiment will be described using Figures 1 to 3. In the following description, the left and right sides of the combine harvester 1, when viewed from the front (left side in Figure 1), will be referred to as the left and right sides of the combine harvester 1, respectively.

[0015] As shown in Figures 1 to 3, the combine harvester 1 comprises a running unit 2 configured as a crawler-type running device having a pair of left and right crawler sections 3, 3, and a running body 4 supported by the running unit 2. The combine harvester 1 comprises a cutting unit 5 for cutting grain stalks, a threshing unit 6 for threshing the grain stalks cut by the cutting unit 5, a grain tank 7 as a grain storage unit for storing the grain removed from the threshing unit 6, and a discharge auger 9 as a grain discharge device for discharging the grain from the grain tank 7. The combine harvester 1 is equipped with an engine 11 as a drive source mounted on the running body 4. The combine harvester 1 is also equipped with a cabin 30 that covers the driver's unit 12.

[0016] Each crawler section 3 constituting the running section 2 has a track frame 3a extending in the front-rear direction below the running body 4, various rotating bodies such as a drive sprocket 3c supported by the track frame 3a, and tracks 3b wound around these rotating bodies. The crawler section 3 is driven by power transmitted from the engine 11 via the drive sprocket 3c.

[0017] The harvesting unit 5 is a device for harvesting and collecting grain stalks such as rice and wheat from a field, and is located at the front of the traveling machine body 4. The harvesting unit 5 is located at the front of the traveling machine body 4 and extends over approximately the entire width of the combine harvester 1. The harvesting unit 5 is mounted on the traveling machine body 4 so as to be rotatable around a predetermined axis via a hydraulic cylinder for lifting and lowering, and its height can be adjusted by the rotational movement caused by the extension and retraction of the hydraulic cylinder.

[0018] The harvesting unit 5 has a harvesting support frame 5a as a harvesting frame, and the grass divider 5b, lifting device 5c, cutting blade device 5e, and grain stalk conveying device 5f are supported on this harvesting support frame 5a. The harvesting unit 5 divides the grain stalks in the field with the grass divider 5b, lifts the divided grain stalks with the lifting device 5c, and while the lifted grain stalks are conveyed to the rear by the grain stalk conveying device 5f, they are cut and harvested by the cutting blade device 5e. The harvesting unit 5 conveys the harvested grain stalks to the threshing unit 6. Each device constituting the harvesting unit 5 is operated by power transmitted from the engine 11.

[0019] On the traveling body 4, the threshing unit 6 and the grain tank 7 are arranged side by side. The threshing unit 6 is located on the left side of the machine, and the grain tank 7 is located on the right side. The combine harvester 1 moves along the traveling body 2 while performing tasks such as cutting the grain stalks with the cutting unit 5 and threshing with the threshing unit 6.

[0020] The threshing unit 6 has a threshing cylinder 6a with the front-to-back direction as the axis of rotation, and a stalk supply device provided to the left of the threshing cylinder 6a. The stalk supply device grips the base of the stalks cut by the harvesting unit 5 and transports the stalks backward in a horizontal position with the ears facing the threshing cylinder 6a. The stalk supply device has a feed chain wound around a plurality of sprockets with the left-to-right direction as the axis of rotation, and a stalk supply clamping body that works in cooperation with the feed chain to grip the base of the stalks.

[0021] Below the threshing unit 6 on the traveling machine body 4, there is a sorting unit 8 for sorting the threshed material processed by the threshing unit 6. The sorting unit 8 includes an oscillating sorting device 8a, an air sorting device, and a grain conveying device. The sorting unit 8 uses the oscillating sorting device 8a to sort the material that has fallen from the threshing unit 6, and then uses the air sorting device to air sort the material after the oscillating sorting. Of the material that has been air sorted, the sorting unit 8 uses the grain conveying device to transport the grain to the right towards the grain tank 7, and uses the air sorting device to blow away straw and dust to the rear and discharge it to the outside of the machine. The grain transported towards the grain tank 7 by the grain conveying device is stored in the grain tank 7.

[0022] A discharge auger 9 is provided on the traveling machine body 4. The discharge auger 9 is rotatably mounted relative to the traveling machine body 4 via a vertical take-off conveyor 9b located on the right rear side of the traveling machine body 4. The discharge auger 9 has a cylindrical auger body 9a with an internal screw conveyor, and a discharge port 9c located at the tip of the auger body 9a, which forms the tip of the discharge auger 9. The discharge auger 9 is also rotatably mounted so as to be able to move up and down around its base.

[0023] The discharge auger 9 is stored in a state where it extends horizontally from the vertical outlet conveyor 9b on the right rear side of the traveling machine body 4 to the left front. In the stored state, in a plan view, the tip of the discharge auger 9 is positioned to the left of the harvesting section 5 and extends along the diagonal of the machine body (see Figure 3). The discharge auger 9 is stored by being placed and supported on the auger rest 27, which serves as the auger receiving section.

[0024] The grain stored in the grain tank 7 is transported by a screw conveyor inside the discharge auger 9 and discharged from the discharge port 9c. The grain discharged from the discharge port 9c is loaded onto a truck bed, container, etc. During the grain discharge operation, the discharge auger 9 rotates from its stowed position to the left or right or up or down direction, moving the discharge port 9c to the outside of the machine.

[0025] On the traveling machine body 4, a straw processing unit 10 is provided behind the threshing unit 6 for processing the straw waste after threshing by the threshing unit 6. The straw processing unit 10 includes a straw conveying device 10a and a straw cutting device 10b. The straw conveying device 10a conveys the threshed grain stalks (waste stalks) to the rear and discharges them outside the machine body, or conveys them to the straw cutting device 10b. The straw cutting device 10b cuts the waste stalks conveyed from the straw conveying device 10a and discharges them outside the machine body.

[0026] On the traveling machine body 4, a driver's unit 12, covered by a cabin 30, is provided to the right of the harvesting unit 5 and in front of the grain tank 7. In other words, the driver's unit 12 is located inside the cabin 30 above the front of the traveling machine body 4. A steering wheel 13 is provided at the front of the driver's unit 12, and a driver's seat 14 is provided behind the steering wheel 13. Various operating devices, including a main gear shift lever 15, are arranged to the left of the driver's seat 14.

[0027] A prime mover unit, including an engine 11, is located below and behind the driver's compartment 12. The power from the engine 11 is transmitted to various devices in each part of the combine harvester 1 via a transmission and the like. The engine 11 is a diesel engine.

[0028] The configuration of the cabin 30 will be explained using Figures 4 to 6. The cabin 30 has a front section 31, a rear section 32, a left side wall section 33, a right side wall section 34, a roof section 35 that forms the ceiling, and a floor section 36, and these parts together form a roughly box-like shape.

[0029] The front portion 31 of the cabin 30 has a forward-sloping front upper portion 31a that constitutes the upper majority of the front portion 31, and a forward-sloping front lower portion 31b that constitutes the roughly lower half of the front portion 31, and as a whole, it has a concave bend shape towards the rear when viewed from the side. The front upper portion 31a is formed as a transparent window portion as a whole by a rectangular transparent plate made of glass, acrylic resin, polycarbonate resin, etc. The front lower portion 31b is made of a metal member such as a steel plate.

[0030] The left side wall 33 of the cabin 30 has a lower side section 41, which is a sheet metal section made of steel plate or the like, at its lower end (see Figure 4). In the left side wall 33, a straight left support column 42 is provided in the middle of the front-rear direction, extending along the vertical direction. The left support column 42 is provided in the upper part of the left side wall 33 so as to extend almost the entire length in the vertical direction.

[0031] In the left side wall section 33, a rectangular left rear window section 43 is provided above the lower side section 41 and behind the left support column section 42. The left rear window section 43 is constructed by attaching a rectangular transparent plate, such as glass, to a frame-like portion formed together with the left support column section 42 by the upper part of the left side plate 44, which forms the rear part of the left support column section 42 in the left side wall section 33. The lower part of the left side plate 44 forms the lower side section 41.

[0032] In the left side wall section 33, the front portion of the left rear window section 43 forms the left front window section 47. The left front window section 47 has a roughly inverted trapezoidal shape, with its front edge aligned with the forward-sloping front upper surface section 31a of the front section 31, and its rear edge aligned with the upper part of the left support column section 42. The left front window section 47 is formed from a rectangular transparent plate made of glass, acrylic resin, polycarbonate resin, etc., and is provided in approximately the same area as the front upper surface section 31a of the front section 31 in the vertical direction.

[0033] In the left side wall section 33, a front upper side plate 57 is provided above the left front window section 47. The front upper side plate 57 forms the upper edge of the portion of the left side wall section 33 that is in front of the left support column section 42. The lower edge of the front upper side plate 57 overlaps the upper edge of the left front window section 47 from the inside (right side).

[0034] A door 48, which is an opening and closing door for boarding and alighting, is provided on the right side wall 34 of the cabin 30. The door 48 is rotatably supported relative to the frame portion of the cabin 30 so as to open outward from the front. The door 48 is rotatably supported vertically in the axial direction by a hinge portion 48a provided at the rear of the right side wall 34, and is designed to open and close from the front. The door 48 is covered with a transparent panel made of glass, acrylic resin, polycarbonate resin, or the like.

[0035] On the right side wall 34, the upper part of the portion in front of the door 48 forms the right front window 49. The right front window 49 has a roughly inverted triangular shape, with its front edge following the forward-sloping inclination of the front upper surface 31a of the front section 31, and its rear edge following the vertical direction. The right front window 49 is formed from a rectangular transparent plate made of glass, acrylic resin, polycarbonate resin, etc., and is provided in approximately the same range as the front upper surface 31a of the front section 31 in the vertical direction.

[0036] In the right side wall 34, a front upper side plate 58 (see Figure 16) is provided above the right front window 49. The front upper side plate 58 forms the portion of the right side wall 34 above the right front window 49 and is provided so as to be substantially flush with the right front window 49. The lower edge of the front upper side plate 58 overlaps the upper edge of the right front window 49 from the inside (left side).

[0037] In the right side wall section 34, the lower part of the portion in front of the door 48, that is, the portion below the right front window section 49, is a sheet metal section made of steel plate or the like, which is the front lower side section 45. The front lower side section 45 has its front edge aligned with the downward slope of the front lower surface section 31b of the front section 31, and its rear edge aligned in the vertical direction. The front lower side section 45 is formed by a rearward bend from the right edge of the member that makes up the front lower surface section 31b of the front section 31.

[0038] A rearview mirror 53 is provided on the right front side of the cabin 30. The rearview mirror 53 has a mirror body 54 with a roughly rectangular shape with the vertical direction as its longitudinal direction, and a mirror arm 55 that supports the mirror body 54, and is provided on the right side wall 34 via a predetermined support member. The rearview mirror 53 supports the mirror body 54 in a hanging position at the front end of the mirror arm 55, and positions the mirror body 54 to the right front of the driver's compartment 12.

[0039] The roof portion 35 of the cabin 30 has a roughly rectangular shape in plan view, with the front-to-rear direction as its longitudinal direction. The front edge of the roof portion 35 protrudes forward in an overhang shape relative to the upper end of the front portion 31, and the rear edge protrudes backward in an overhang shape relative to the upper end of the rear portion 32. Multiple lighting units 51 are arranged side by side on the front end surface of the roof portion 35 (see Figure 6).

[0040] The roof section 35 has a flattened outer shape and is hollow. The roof section 35 has a lower panel (not shown) that forms the base of the roof section 35 and a roof panel 50 provided above the lower panel, and these panels form a hollow section. The roof panel 50 has an upper surface 50a and left and right side surfaces 50b that are bent downward on both the left and right sides of the upper surface 50a. The roof panel 50 is a cover member provided to cover the lower panel section entirely from above and on both the left and right sides.

[0041] Furthermore, the left side portion 50b of the roof panel 50 covers the upper edge of the left wall portion 33 from the left, and the right side portion 50b of the roof panel 50 covers the upper edge of the right wall portion 34 from the right. Inside the roof portion 35 are the indoor unit of the air conditioning system installed in the combine harvester 1.

[0042] In the cabin 30 having the above configuration, the left side of the cabin 30 is formed by the left side wall 33 and the left portion of the roof 35. The right side of the cabin 30 is formed by the right side wall 34 and the right portion of the roof 35. Hereinafter, the left side of the cabin 30, including the left side wall 33 and the left portion of the roof 35, will be referred to as the left side of the cabin 37.

[0043] The combine harvester 1 according to this embodiment includes an antenna unit 60 for receiving positional information from a satellite. The antenna unit 60 is located on the upper part of the left side surface 37 of the cabin 30, one of the left and right side surfaces of the cabin 30. The antenna unit 60 is supported by a predetermined support member relative to the cabin 30 so as to be located near the left side of the upper part of the left side surface 37 of the cabin.

[0044] The antenna unit 60 has a box-like outer shape that is roughly rectangular in plan view, and is installed with its longitudinal direction as the front-to-back direction. The antenna unit 60 is installed at approximately the same height as the roof portion 35 in the vertical direction. Specifically, the vertical dimensions of the antenna unit 60 are approximately the same as the vertical dimensions of the side portion 50b of the roof panel 50, and the antenna unit 60 is installed so that approximately its entire vertical dimension is within the height range of the side portion 50b of the roof panel 50.

[0045] The antenna unit 60 is positioned, in the front-rear direction, either entirely or substantially entirely, in front of the left support column 42 provided on the left side surface 37 of the cabin. Specifically, in the front-rear direction, the rear end of the antenna unit 60 is positioned near the upper end of the left support column 42, and is positioned along the upper edge of the left front window 47 when viewed from the left side. The antenna unit 60 has approximately the same length as the upper edge of the left front window 47 in the front-rear direction. In the front-rear direction, the antenna unit 60 has a dimension of approximately 1 / 3 of the total length of the roof section 35 and is positioned to the left front of the roof section 35 (see Figure 7).

[0046] The antenna unit 60 is positioned such that its right side is directly to the left of the left side portion 50b of the roof panel 50. In this way, the antenna unit 60 is positioned adjacent to the left of the front portion of the roof 35 relative to the cabin 30.

[0047] With this arrangement of the antenna unit 60, in a configuration where the cabin 30 is located on the front right side of the combine harvester 1, the antenna unit 60 is positioned approximately in the center of the machine in the left-right direction (see Figure 3). Furthermore, since the antenna unit 60 is located to the front left of the roof section 35, the light distribution from the lighting section 51 and the field of view from inside the cabin 30 are not obstructed by the antenna unit 60. In addition, a space is formed between the cabin 30 and the discharge auger 9 in its stowed state on the left side, and the antenna unit 60 is positioned utilizing this space.

[0048] The antenna unit 60 is configured as a positioning unit for receiving radio waves from positioning satellites to measure the position of the combine harvester 1. The antenna unit 60 comprises a receiving device 61 as a receiving unit, an inertial navigation device 62 as a calculation unit, a wireless communication device 63 as a communication unit, and a case 64 that houses these devices. The antenna unit 60 constitutes the automatic steering system of the combine harvester 1.

[0049] The receiving device 61 receives radio waves from positioning satellites, converts the received radio waves into signals, and transmits them to the inertial navigation device 62. The receiving device 61 is, for example, a GNSS receiver (GNSS antenna) that receives radio waves from a constellation of GNSS satellites, or a GPS receiver (GPS antenna) that receives radio waves from GPS (Global Positioning System) satellites.

[0050] The inertial navigation system 62 measures 3-axis gyroscopes and 3-directional acceleration to calculate attitude and heading data. The inertial navigation system 62 also calculates position data based on signals transmitted from the receiver 61. The inertial navigation system 62 functions as a computing device that calculates position data based on position information from the receiver 61. For example, by equipping the inertial navigation system 62 with a GNSS receiver, the reliability of the attitude and heading data calculated by the inertial navigation system 62 is improved.

[0051] The antenna unit 60 is equipped with an inertial navigation device 62, which enables the use of inertial navigation to determine position even in situations where radio waves from positioning satellites cannot be received due to bad weather, radio interference, etc., by calculating the speed of movement, distance traveled, etc., based on the acceleration in three directions detected by the inertial navigation device 62.

[0052] The wireless communication device 63 transmits position data and attitude / direction data calculated by the inertial navigation device 62 to an external device via wireless communication. The wireless communication device 63 is a data communication device that uses, for example, a wireless LAN (Local Area Network) or mobile communication. The data transmitted from the wireless communication device 63 is received by, for example, a mobile terminal held by the operator or the ECU (Electronic Control Unit) of the combine harvester 1, and is used for confirming the position within the field and confirming the attitude of the combine harvester 1 (tilt to the front, back, left, and right, etc.).

[0053] The case 64 has a lower case body 65 that forms the lower part of the case 64 and an upper case body 66 that forms the upper part of the case 64, and these case bodies form the housing space and the external shape of the antenna unit 60. The case 64 has a relatively flat box-like external shape with the front-to-back direction as its longitudinal direction due to the lower case body 65 and the upper case body 66. The lower case body 65 and the upper case body 66 are made of, for example, resin.

[0054] The lower case body 65 is a box-shaped member with an open top, and has a horizontal bottom surface 65a and a peripheral wall 65b that includes the front, rear, left, and right side surfaces and forms a rectangular opening with its upper edge (see Figure 8). The upper case body 66 is a lid-like part that covers the opening of the lower case body 65 from above. The upper case body 66 has a rectangular edge formed by its front, rear, left, and right surfaces, and is provided in a state where this edge is fitted into the rectangular opening of the lower case body 65. The upper case body 66 is fitted into the lower case body 65 with its lower opening edge overlapping the upper opening edge of the lower case body 65 from the outside, and the two case bodies are fixed to each other at multiple points by fasteners 67 such as bolts (see Figure 8) that pass through the fitting portions of each other.

[0055] Within the case 64, the wireless communication device 63, the receiving device 61, and the inertial navigation device 62 are arranged in that order from front to rear, with predetermined intervals between them. These devices are fixed within the case 64 to a mounting plate (not shown) provided on the upper side of the bottom surface 65a of the lower case body 65 by fasteners such as bolts.

[0056] As described above, the antenna unit 60 is configured as an integrated unit in which a receiving device 61, an inertial navigation device 62, and a wireless communication device 63 are housed within a case 64.

[0057] The positioning data (location data and attitude / direction data) acquired by the antenna unit 60 is used to control the autonomous combine harvester 1, which operates autonomously while traveling along a pre-set route. The location data is used, for example, to determine whether the combine harvester 1 is traveling along a predetermined route. The attitude / direction data is used, for example, to recognize the inclination of the combine harvester 1, thereby confirming the travel status of the combine harvester 1 and the condition of the field. In addition, the operator can send real-time instructions to the combine harvester 1 by receiving data transmitted from the wireless communication device 63.

[0058] The configuration of the antenna unit 60 is not limited to this embodiment. For example, the antenna unit 60 may be configured such that the receiving device 61 functions as a calculation unit that calculates position data from the position information received by the receiving device 61, thereby omitting the inertial navigation device 62.

[0059] The support configuration of the antenna unit 60 will be explained using Figures 6 to 8. Note that in Figure 8, a portion of the roof panel 50 is shown cut out.

[0060] The combine harvester 1 is equipped with a support frame 70 as an antenna support member that supports the antenna unit 60. The support frame 70 is a frame portion made of a metal round pipe-shaped member having a predetermined bent or curved shape, and is provided on the left side surface 37 of the cabin.

[0061] The support frame 70 is configured to extend in the front-rear direction. The support frame 70 has a frame body that extends substantially in the front-rear direction for the majority of its length, excluding both front and rear ends. In a left side view, the support frame 70 is located near the lower edge of the left side portion 50b of the roof panel 50 and is provided to follow the left side portion 50b of the roof panel 50. The support frame 70 has a bent shape made of pipe-shaped members, and from the front to the rear, it has, in order, a front fixing portion 71, a front-rear extending portion 72, an inclined portion 73, and a rear fixing portion 74 (see Figure 7).

[0062] The front fixing portion 71 is a portion whose axis is oriented in the left-right direction, and extends to the left from the left side surface portion 37 of the cabin. The right end of the front fixing portion 71 becomes the front end of the support frame 70. The front and rear extension portion 72 is a portion whose axis is oriented in the front and rear direction, and extends horizontally toward the rear from the left end of the front fixing portion 71, forming a right-angle corner together with the front fixing portion 71.

[0063] The inclined portion 73 is a part whose axial direction is such that, in a plan view, it gradually slopes from the front to the rear, from the left side outward to the right side inward. The rear fixing portion 74 is a part whose axial direction is the left-right direction, and it extends horizontally to the right from the rear end of the inclined portion 73, forming an obtuse angle together with the inclined portion 73. The right end of the rear fixing portion 74 becomes the rear end of the support frame 70.

[0064] The support frame 70 is installed with its front and rear ends fixed to the left side surface 37 of the cabin. Specifically, the support frame 70 is installed with the right end of the front fixing part 71, which is the front end, and the right end of the rear fixing part 74, which is the rear end, fixed to the left side surface 37 of the cabin.

[0065] The front end of the support frame 70 is located near the upper end of the front upper surface 31a that constitutes the front surface 31 on the left side surface 37 of the cabin. The front end of the support frame 70 is fixed to the front upper side plate 57 that constitutes the front upper part of the left side surface 37 of the cabin via a front mounting plate 76 (see Figure 8).

[0066] The front mounting plate 76 is oriented with its thickness in the left-right direction and is fixed to the front upper side plate 57 at two points, front and back, by fixing bolts 78. The right end of the front fixing portion 71 of the support frame 70 is fixed to the front mounting plate 76 by welding or the like.

[0067] The rear end of the support frame 70 is located near the rear upper corner of the left rear window section 43 on the left side surface 37 of the cabin. The rear end of the support frame 70 is fixed to the upper end of the left side plate 44 that forms the rear of the left side surface 37 of the cabin via a rear mounting plate 81 (see Figure 8).

[0068] The rear mounting plate 81 is oriented with its thickness in the left-right direction and is fixed to the left side plate 44 at two points, top and bottom, by fixing bolts 82. The right end of the rear fixing portion 74 of the support frame 70 is fixed to the rear mounting plate 81 by welding or the like.

[0069] As described above, the antenna unit 60 is supported on the front part of the support frame 70, which is fixedly supported to the cabin 30. The antenna unit 60 is supported in a fixed state by support brackets 90 provided at two locations, front and rear, on the front and rear extensions 72 of the support frame 70.

[0070] The support bracket 90 is fixed to a mounting bracket 91 which is fixed to the support frame 70. In other words, the support bracket 90 is provided to the support frame 70 via the mounting bracket 91. The support bracket 90 and the mounting bracket 91 are configured to be symmetrical or approximately symmetrical with respect to the axis of the front and rear extension portion 72 of the support frame 70. Furthermore, the front and rear sets of support brackets 90 and mounting brackets 91 are configured to be symmetrical or approximately symmetrical with respect to the front and rear directions.

[0071] The mounting bracket 91 is a longitudinal member formed by bending a plate-shaped member, and is provided above the front and rear extensions 72 so as to be perpendicular to the axial direction of the front and rear extensions 72 in a plan view, with the longitudinal direction being the left-right direction. The mounting bracket 91 has a front and rear portion and an upper portion that are parallel to each other, and these portions form a roughly "U" shape with the lower side open in a side view. The mounting bracket 91 is fixed to the front and rear extensions 72 by welding or the like, with the front and rear extensions 72 fitted into semicircular notches in the left and right center portions of the front and rear portions.

[0072] The support bracket 90 is a longitudinal member formed by bending a plate-shaped member, and is provided above the front and rear extension portion 72 so as to be perpendicular to the axial direction of the front and rear extension portion 72 in a plan view, with the longitudinal direction being the left-right direction. The support bracket 90 has approximately the same length as the mounting bracket 91.

[0073] The support bracket 90 has a fixed surface portion whose front-to-back direction is the thickness direction of the plate, a horizontal support surface portion formed by bending at a right angle from the upper end of the fixed surface portion, and left and right side portions formed by bending at right angles from both the left and right ends of the fixed surface portion. In the support bracket 90, the upper support surface portion is the surface portion that receives the mounting of the case 64 of the antenna unit 60. The front and rear support brackets 90 are fixed to the mounting bracket 91 at two points on both the left and right ends by fixing bolts 92 or the like, to the front or rear surface portion of the mounting bracket 91.

[0074] The case 64 of the antenna unit 60 is fixed to these front and rear support brackets 90 by fixing bolts 96. The fixing points for the fixing bolts 96 are provided at two locations on both the left and right sides of each support bracket 90. In this way, the antenna unit 60 is fixed to the front and rear support brackets 90 at two locations each, for a total of four locations, by fixing bolts 96. Each fixing bolt 96 penetrates the support surface of the support bracket 90 from below and is screwed into a female threaded portion 97, which is a cylindrical member provided inside the case 64 that opens a screw hole facing the bottom surface 65a of the lower case body 65.

[0075] As described above, the antenna unit 60 is supported by a support frame 70 on the upper left side of the cabin 30, and a handrail 100 is provided. The handrail 100 is used for performing work on the antenna unit 60. The handrail 100 is made of a metal round pipe-shaped member having a predetermined bent or curved shape, and is provided on the left side surface 37 of the cabin 30.

[0076] The handrail section 100 is configured to extend vertically. The majority of the handrail section 100, excluding the upper and lower ends, is a handrail body that extends vertically when viewed from the side. The handrail section 100 has a bent shape made of pipe-shaped members, and from the bottom to the top, it has, in order, a lower fixing section 101, an inclined extension section 102, and an upper fixing section 103.

[0077] The lower fixing portion 101 is a part whose axis is oriented in the left-right direction, and it extends to the left from the left side surface portion 37 of the cabin. The right end of the lower fixing portion 101 becomes the lower end of the handrail portion 100.

[0078] The inclined extension portion 102 is a portion whose axial direction is along the vertical direction in a side view, and gradually slopes from the lower side to the upper side from the left and right inward (right side) to the left and right outward (left side) in a front view. The inclined extension portion 102 is a portion that extends diagonally upward and to the left, forming an obtuse angle together with the lower fixing portion 101 in a front view.

[0079] The upper fixing portion 103 is a part whose vertical direction is axial, and it extends upward from the upper end of the inclined extension portion 102, forming an obtuse-angled corner together with the inclined extension portion 102. The upper end of the upper fixing portion 103 becomes the upper end of the handrail portion 100. In a left side view, the handrail portion 100 is positioned so that it largely overlaps the left support portion 42 that constitutes the left side surface portion 37 of the cabin.

[0080] The handrail portion 100 is provided with its upper end connected to the support frame 70 and its lower end fixed to the left side surface portion 37 of the cabin. In other words, the handrail portion 100 is provided with the upper end of the upper fixing portion 103 connected to the support frame 70 and the right end of the lower fixing portion 101 fixed to the left side surface portion 37 of the cabin.

[0081] The upper end of the handrail section 100 is connected to the support frame 70 via an upper support bracket 110, which is an upper connecting member fixed to the support frame 70. The upper support bracket 110 is provided on the lower side of the support frame 70, in the portion between the rear support bracket 90 and the corner formed by the front and rear extension section 72 and the inclined section 73.

[0082] The upper support bracket 110 is a member formed by bending a plate-shaped member into a predetermined shape. The upper support bracket 110 has a roughly rectangular fixed surface portion 110a with the left-right direction as the plate thickness direction, and front and rear side portions 110b that are bent at right angles from the front and rear ends of the fixed surface portion 110a toward the left and right inward (right side) (see Figure 8). These surfaces form a roughly "U" shape with the right side as the open side when viewed from above. In the upper support bracket 110, the fixed surface portion 110a is the surface portion that receives the attachment of the upper end of the handrail portion 100.

[0083] A concave notch 110c is formed on the upper left side of the front and rear side portions 110b of the upper support bracket 110 for fitting the front and rear extension portions 72 of the support frame 70 (see Figure 8). The upper support bracket 110 is fixed to the front and rear extension portions 72 by welding or the like, with the front and rear extension portions 72 positioned within the notches 110c of the front and rear side portions 110b. The upper edge of the fixed surface portion 110a of the upper support bracket 110 is positioned to the left of the front and rear extension portions 72.

[0084] The handrail section 100 is fixed to the upper support bracket 110 at the upper end of the upper fixing section 103 via a fixing plate 115. The fixing plate 115 is a plate-like member having an outer shape of a roughly truncated isosceles triangle, with the plate thickness direction as the left-right direction and the top side facing downwards. The fixing plate 115 is fixed to the left side of the upper end of the upper fixing section 103 by welding or the like. The fixing plate 115 overlaps the fixing surface section 110a of the upper support bracket 110 from the back side (right side) and is fixed to the fixing surface section 110a at two points, front and back, by fixing bolts 116 or the like.

[0085] The lower end of the handrail portion 100 is fixed to the lower side portion 41 that constitutes the left side portion 37 of the cabin via a lower support bracket 120, which is a mounting member. The lower support bracket 120 is a mounting fitting that has a roughly "L"-shaped bend when viewed from above. The lower support bracket 120 is fixed to the lower side portion 41 by fixing bolts 124 with one of its roughly "L"-shaped surfaces aligned with the lower side portion 41 as the fixing surface. The other roughly "L"-shaped surface of the lower support bracket 120, which is the support surface, protrudes to the left from the front of the fixing surface 121. The handrail portion 100 is fixed to the lower support bracket 120 by welding or the like with respect to the lower support bracket 120, with the lower fixing portion 101 positioned behind the support surface.

[0086] As described above, the handrail section 100 is connected and supported at its upper end to the support frame 70 and at its lower end to the left side surface 37 of the cabin, and is installed in a state where it is suspended between the support frame 70 and the left side surface 37 of the cabin.

[0087] The combine harvester 1 according to this embodiment is equipped with two stacked lights 150 as a status display device that displays information used to notify the various states of the combine harvester 1. The combine harvester 1 is equipped with a stacked light 150A, which is a first stacked light, located on the left side of the cabin 30, and a stacked light 150B, which is a second stacked light, located on the right side of the cabin 30.

[0088] The stacked lamp 150 has a cylindrical outer shape and is installed in an upright position with its central axis oriented vertically. The stacked lamp 150 has a cylindrical outer surface portion 151 and flat surfaces portion bottom 152 and top 153 as the surfaces that make up its cylindrical outer shape.

[0089] The stacked lamp 150 has a light-emitting display section 154 in its upper half, which is formed by stacking multiple indicator light sections. The light-emitting display section 154 has a configuration in which, from top to bottom, the following are stacked indicator light sections: a first indicator light section 154a that emits red light, a second indicator light section 154b that emits yellow light, and a third indicator light section 154c that emits green light (see Figure 10). Each indicator light section includes a light source such as an LED.

[0090] The configuration of the stacked lamp 150, such as the stacking order of the indicator light units that emit light of each color, the types of colors emitted by each indicator light unit, the number of stacked indicator light units, and the structure for emitting light, is not limited. Furthermore, the display mode of the stacked lamp 150 is also not limited. For example, the display mode of the stacked lamp 150 may include turning off all indicator light units, lighting multiple indicator light units simultaneously, or using flashing indicator light displays.

[0091] The stacked lamp 150 is connected to a controller (not shown) which constitutes the control unit of the combine harvester 1 via a connection cord 155, which is a connecting wire extending from the bottom portion 152, and the display operation of the stacked lamp 150 is controlled by the controller. The controller has a configuration in which various functional units such as a CPU (Central Processing Unit) that performs various calculations and controls, ROM (read-only memory) as a storage unit, RAM (random access memory), and input / output interfaces are connected by a bus or the like. The CPU performs calculations according to various programs stored in the ROM, etc.

[0092] The controller illuminates one of the indicator lights on the stacked lamp 150's light-emitting display section 154 based on signals input from various sensors and switches located in different parts of the combine harvester 1, as well as the operating mode of the antenna unit 60, thereby notifying the various statuses of the combine harvester 1. The content notified by the stacked lamp 150 is not particularly limited. Furthermore, the two stacked lamps 150 equipped on the combine harvester 1 are controlled to display the same information.

[0093] The red light emitted by the first indicator light unit 154a is used, for example, to warn or alert the user if any trouble occurs in the combine harvester 1. Specifically, for example, if there is a blockage of grain stalks in the threshing unit 6, if the amount of grain in the grain tank 7 becomes full, or if there is an abnormality in the cooling water temperature of the engine 11, the first indicator light unit 154a will light up to provide notification. The yellow light emitted by the second indicator light unit 154b is used, for example, as a preliminary warning before the above-mentioned trouble occurs, or as a notification of obstacle detection during automatic machine operation. The green light emitted by the third indicator light unit 154c is used to indicate that the combine harvester 1 is ready to start work or is operating normally.

[0094] Furthermore, the stacked lamps 150 may be used to notify the status of the combine harvester 1 according to the reception status of the antenna unit 60's receiving device 61. In this case, for example, the stacked lamps 150 are controlled to light up the green third indicator light 154c when the antenna unit 60's radio wave reception status is in a suitable reception mode, light up the yellow second indicator light 154b when the reception status is in an unstable reception state, and light up the red first indicator light 154a when the reception status is in a no-reception state.

[0095] In the configuration in which the stacked lamps 150 described above are provided on both the left and right sides of the cabin 30, the arrangement and support configuration of each stacked lamp 150 in the combine harvester 1 will be explained with reference to Figures 3, 4 to 18.

[0096] The arrangement and support configuration of the stack lamp 150A located on the left side of the cabin 30 will now be described. The stack lamp 150A is installed supported by the auger rest 27, which supports the discharge auger 9 and puts the discharge auger 9 in a retracted state. The stack lamp 150A is installed supported by a stack lamp support part 160, which is a support part provided on the auger rest 27. In other words, the stack lamp 150A is supported by the auger rest 27 via the stack lamp support part 160.

[0097] The auger rest 27 is positioned to the left of the rear of the cabin 30 and supports a predetermined portion of the auger body 9a of the discharge auger 9 from below, in the middle of its extension direction. The auger rest 27 has an auger rest main body 170 on which the auger body 9a of the discharge auger 9 is placed and supported, and an auger rest support column 171 that extends downward from the auger rest main body 170 and supports the auger rest main body 170.

[0098] The auger rest body 170 is configured as a curved plate-like portion with a concave shape, with the upper side open, to house and support the discharge auger 9 while the cylindrical auger body 9a is positioned. The auger rest body 170, when viewed in the central axis direction of the auger body 9a, has a roughly arc-shaped curved section in the middle left and right, and as a whole, is roughly "V" shaped, with the upper surface serving as a support surface 170a that receives contact from the auger body 9a. The support surface 170a, in its middle left and right sections, follows the roughly arc shape when viewed in the central axis direction of the auger body 9a and is a concave curved surface that follows a part of the roughly cylindrical surface of a size corresponding to the outer diameter of the auger body 9a. Furthermore, both ends of the auger rest body 170 extend diagonally upward so as to be tangential to the auger body 9a in the housed state when viewed in the central axis direction of the auger body 9a.

[0099] A rib plate 172 is provided on the lower side of the auger rest main body 170, following the curved shape of the auger rest main body 170. The rib plate 172 is located in the center of the width direction of the auger rest main body 170 (the axial direction of the auger body 9a in the stored state), and is provided so that the thickness direction is approximately the same as the axial direction of the auger body 9a in the stored state. The rib plate 172 is fixed to the auger rest main body 170 by welding or the like, so that it is provided as an integral part of the auger rest main body 170.

[0100] The Augerest support column 171 is a rectangular prism-shaped portion having a front portion 171a, a rear portion 171b, a left side portion 171c, and a right side portion 171d, and is provided hanging down from a position slightly to the right of the left-right center of the Augerest main body portion 170. The Augerest support column 171 has an inclined shape at its upper end so as to follow the lower surface of the Augerest main body portion 170, and is located behind the rib plate 172, and is fixed to the Augerest main body portion 170 and the rib plate 172 by welding or the like.

[0101] The Augerest support column 171 has a configuration in which the rear side of a U-shaped channel steel member, which forms the front portion 171a, left side portion 171c, and right side portion 171d, is closed by a plate-shaped member forming the rear portion 171b (see Figure 13). The two members forming the Augerest support column 171 are fixed to each other by welding or the like. The Augerest support column 171 may also be a portion made of a square steel pipe or the like.

[0102] The Augerrest 27 is supported by a front central support column 175 located at the front of the running machine body 4. The front central support column 175 is erected on the machine base section 25 (see Figure 1) that constitutes the running machine body 4 via a predetermined support section. In other words, the Augerrest 27 is provided to the machine base section 25 via the front central support column 175. The machine base section 25 is a base section horizontally constructed by frame members and plate-like members arranged in the front-rear and left-right directions on the track frame 3a that constitutes the crawler section 3. The engine 11, threshing unit 6, and grain tank 7 are mounted on the machine base section 25.

[0103] The front central support column 175 is located in the left-right center of the front part of the machine base 25, between the front end of the threshing unit 6 and the engine 11. The front central support column 175 is a rectangular prism-shaped part having a front part 175a, a rear part 175b, a left side part 175c, and a right side part 175d, and is formed from a rectangular steel pipe. The front central support column 175 has a horizontal upper part 175e.

[0104] The organ rest support section 171 is fixedly supported to the upper end of the front central support 175 via a mounting frame 176. The mounting frame 176 is formed from a channel steel member with a U-shaped cross-section, with the front side open, and is attached to the rear side of the front central support 175, thereby forming a rectangular tubular insertion space 177 into which the organ rest support section 171 is inserted together with the front central support 175 (see Figure 13).

[0105] The mounting frame 176 has a U-shaped cross-section and includes a left side portion 176a, a right side portion 176b, and a rear side portion 176c. The rear of the front central support column 175 is positioned between the front edges of the left side portion 176a and the right side portion 176b, and each side portion is fixed to the left side portion 175c and the right side portion 175d of the front central support column 175 by welding or the like.

[0106] The Augerest 27 is fastened to the mounting frame 176 at two points, top and bottom, by bolts 178 and nuts 179, with the Augerest support column 171 inserted into the insertion space 177 from above. The bolt 178 passes through the left side of the mounting frame 176a and right side of the mounting frame 176, and the left side of the Augerest support column 171c and right side of the Augerest support column 171, from the left side, and is screwed into the nut 179 on the right side of

[0107] The bolt 178 passes through a cylindrical sleeve 180 provided inside the organ rest support column 171 (see Figure 13). In the organ rest support column 171, a bolt insertion portion 182 is formed by holes in the left side portion 171c and the right side portion 171d, and the sleeve 180 with open ends that communicates with these holes, through which the bolt 178 passes.

[0108] As described above, the stack lamp support section 160, which supports the stack lamp 150A, is attached to the organest 27, which is supported by the front central support column 175, by the organest support column 171. The stack lamp support section 160 has an arm plate 161 and a support stay 162.

[0109] The arm plate 161 is a rectangular plate-shaped member, with its thickness oriented in the front-to-back direction and its length oriented in the left-to-right direction, and is attached to the portion of the organ rest support 171 that extends downward from the rib plate 172. The right end of the arm plate 161 is fixed to the front portion 171a of the organ rest support 171, and it protrudes to the left from the organ rest support 171. The right end of the arm plate 161 is overlapped with the organ rest support 171 from the front and fixed to the organ rest support 171 at two points, top and bottom, by fixing bolts 163.

[0110] The support stay 162 is made of a bent plate-shaped member and has a horizontal support base 164 located below the organest main body 170 for supporting the stacked lamp 150. The support base 164 is provided to the arm plate 161 via the stay body 165. The stay body 165, together with the support base 164, constitutes the support stay 162, which is an integrated component.

[0111] The stay body 165 has a fixed surface portion 165a that overlaps the arm plate 161 from the front, a support surface portion 165b located to the left of the fixed surface portion 165a and forming a ridge along the vertical direction together with the fixed surface portion 165a, and an upper surface portion 165c that covers the corner formed by the fixed surface portion 165a and the support surface portion 165b from above. The fixed surface portion 165a has a roughly right-angled triangular shape with the upper left corner being the right-angled corner when viewed from the front. The support surface portion 165b has a roughly trapezoidal shape that is elongated vertically when viewed from the side.

[0112] The support surface portion 165b extends diagonally forward to the left from the left end of the fixed surface portion 165a, and together with the fixed surface portion 165a, forms an obtuse angle (for example, about 110°) in a plan view. The upper surface portion 165c is formed as a right-angle bend to the right from the upper end of the support surface portion 165b, and has a roughly triangular shape corresponding to the shape of the angle formed by the fixed surface portion 165a and the support surface portion 165b.

[0113] The stay body 165 has its upper part fixed to the arm plate 161, and its lower part protrudes downward from the left side of the arm plate 161. The stay body 165 has its fixing surface 165a overlapping the arm plate 161 from the front, and is fastened and fixed to the arm plate 161 at two points, top and bottom, by fixing bolts 166 and nuts 167.

[0114] The support base 164 has a support surface 164a that forms a horizontal mounting support surface for the stacked lamp 150A, and bent surface 164b that are bent at a right angle downward from the support surface 164a on both the front and rear sides of the support surface 164a. The support surface 164a has a roughly rectangular outer shape in plan view, and is provided inclined in the front, rear, left, and right directions in plan view so that a pair of opposing sides of the rectangular outer shape in plan view are aligned with the extension direction of the auger body 9a in the stored state. Although this is just one example, the inclination angle of the support base 164 in the left and right directions in plan view is approximately 20°.

[0115] The lower end of a bent plate-shaped member forming the stay body 165 is fixed to the right side of the support surface portion 164a by welding or the like. The support base portion 164 extends diagonally to the left and rear from the lower end of the stay body 165.

[0116] In the support base portion 164, the stacked lamp 150A is placed and supported on the support surface portion 164a. The support surface portion 164a has dimensions that position the entire stacked lamp 150A, which has a circular outer shape in plan view, within the range of its outer shape. The stacked lamp 150A is fixedly supported on the support surface portion 164a, with the upper surface of the support surface portion 164a, which contacts the bottom surface portion 152, serving as the mounting surface.

[0117] The stack lamp 150 has multiple (three) threaded portions 156 that protrude downward from the bottom portion 152 (see Figure 11). The stack lamp 150A is fastened and fixed to the support surface portion 164a of the support base portion 164 by passing the threaded portions 156 through the support surface portion 164a of the support base portion 164 from above and screwing the threaded portions 156 into nuts 157 on the underside of the support surface portion 164a. Multiple holes are formed in the support surface portion 164a through which the threaded portions 156 pass. In addition, an opening 164c is formed in the support surface portion 164a for passing a connecting cord 155 that extends from the bottom portion 152 of the stack lamp 150 (see Figure 12).

[0118] In the support configuration of the stacked lamp 150A described above, the stacked lamp 150A is positioned below the discharge auger 9 in its stored state in the vertical direction. The stacked lamp 150A, which is supported and fixed on the support base portion 164, has its upper surface portion 153 positioned below the lower end of the support surface 170a of the auger rest main body portion 170 in the vertical direction.

[0119] In other words, as shown in Figure 10, the height position H1 of the upper surface portion 153 of the stacked lamp 150A is located below the height position H2 of the lower end of the support surface 170a of the auger rest body portion 170. Here, the height position H2 of the lower end of the support surface 170a is the height position of the lower end of the left and right central portion that forms a downwardly convex arc shape when viewed in the central axis direction of the auger body portion 9a in the stored state on the support surface 170a.

[0120] In this configuration, the discharge auger 9 is stored in a manner in which the auger body portion 9a is fitted onto the support surface 170a, and the stacked lamp 150A is positioned so that its entirety is below the lower end of the outer peripheral surface of the auger body portion 9a. In this embodiment, the stacked lamp 150A is provided so that its upper portion 153 is positioned below the height position H3 of the lower end of the auger rest body portion 170, and at the height of the upper and lower intermediate portion of the rib plate 172.

[0121] Furthermore, as shown in Figure 7, the stacked lamp 150A is positioned such that, in a top view, most of its right side (left side in Figure 7) relative to the discharge auger 9 in its retracted state is covered by the auger body 9a. In other words, the stacked lamp 150A is positioned such that, in a top view, a portion of its left side is exposed to the left of the auger body 9a in its retracted state. In addition, in a plan view, the stacked lamp 150A is positioned so that almost its entirety is located in front of the auger rest body 170.

[0122] Furthermore, the stacked lamp 150A is positioned so as to overlap with the rear end of the left side portion 37 of the cabin when viewed from the left side. In particular, the stacked lamp 150A is positioned near the left rear of the left rear window portion 43 that forms the left side portion 37 of the cabin. With this configuration, the stacked lamp 150A can be easily accessed from inside the cabin 30 through the left rear window portion 43. As a result, the operator inside the cabin 30 can access the stacked lamp 150A by opening the left rear window portion 43, making it easy to perform maintenance such as removing dust and dirt adhering to the stacked lamp 150A. The left rear window portion 43 is configured to be openable and closable by a hinge portion (not shown).

[0123] Furthermore, the auger rest 27, which supports the stacked lamp 150A via the stacked lamp support section 160, is provided in a height-adjustable manner to change the support position of the discharge auger 9. The height of the auger rest 27 is changed by changing the support position of the auger rest support section 171 relative to the front central support column 175 in the vertical direction.

[0124] Specifically, in the Augerest support column 171, which is fixed by bolts 178 at two locations, upper and lower, there are two sets of bolt insertion parts 182 through which the bolts 178 pass. In other words, the Augerest support column 171 is provided with two first bolt insertion parts 182A, upper and lower, which fix the Augerest support column 171 to the mounting frame 176 at a first height position, and two second bolt insertion parts 182B, upper and lower, which fix the Augerest support column 171 to the mounting frame 176 at a position higher than the first height position (see Figure 11). The lower second bolt insertion part 182B is located between the upper and lower first bolt insertion parts 182A.

[0125] Thus, the Augerrest 27 is provided so as to be vertically adjustable by having a first bolt insertion part 182A and a second bolt insertion part 182B in the Augerrest support column 171. In other words, the fixing position of the Augerrest support column 171 with respect to the front central support column 175 erected on the running machine body 4 can be adjusted in two stages: a low position using a pair of first bolt insertion parts 182A and a high position using a pair of second bolt insertion parts 182B.

[0126] By adjusting the height of the Augerrest 27, the height position of the stacked lamp 150A, which is supported by the Augerrest support column 171 via the stacked lamp support 160, is adjusted. In other words, the stacked lamp 150A changes its height integrally with the Augerrest 27 as its height is adjusted. Therefore, the stacked lamp 150A, like the Augerrest 27, is provided to be height-adjustable in two stages: a low position and a high position. Figures 9, 10, and 12 show the Augerrest 27 and stacked lamp 150A in the low position, while Figure 11 shows the Augerrest 27 and stacked lamp 150A in the high position.

[0127] The arrangement and support configuration of the stacked lamp 150B located on the right side of the cabin 30 will be explained using Figures 5 to 7 and Figures 14 to 18. Note that in Figures 14, 15, and 16, a portion of the roof panel 50 is shown cut out.

[0128] The stacked lamp 150B is supported on the cabin 30 using the support configuration of the rearview mirror 53 on the cabin 30. That is, the stacked lamp 150B is supported on the support configuration of the rearview mirror 53 which is provided on the right side wall 34 of the cabin 30. The rearview mirror 53 is rotatably supported on the right side handrail 200 provided on the right side wall 34 of the cabin 30 via a mirror stay 210.

[0129] The handrail section 200 is made of a metal round pipe-shaped member having a predetermined bent or curved shape, and is provided on the right side wall section 34 of the cabin 30. The majority of the upper part of the handrail section 200 is a handrail body section 201 that extends in the vertical direction, and at the lower end, it has a lower bent section 202 and a lower fixing section 203 as a bent shape made of a pipe-shaped member (see Figures 5 and 6).

[0130] In a right-side view, the handrail section 200 is positioned so that substantially the entire handrail body 201 overlaps the right front window section 49, which constitutes the right-side wall section 34. Furthermore, the handrail section 200 is installed so that the handrail body 201 is positioned to the right of the right front window section 49, with a predetermined distance between them.

[0131] The lower bent portion 202 is a section that bends obtusely downward and backward relative to the handrail body 201 when viewed from the right side. The lower fixing portion 203 is a section that curves inward (to the left) from the lower end of the lower bent portion 202. The left end of the lower fixing portion 203 becomes the lower end of the handrail 200, and the opening of the pipe-shaped member is oriented to the left.

[0132] The handrail section 200 is provided with its upper end fixed to the front upper side plate 58 that constitutes the right side wall section 34 via a mounting plate 205, and its lower end fixed to the front lower side section 45 below the right front window section 49.

[0133] The mounting plate 205 is a bent plate-shaped member that is curved to form a crank shape when viewed from the front, and the bent portion has a vertical fixing surface portion 205a, a horizontal lateral support surface portion 205b, and a vertical longitudinal support surface portion 205c. The mounting plate 205 is fixed to the front upper side plate 58 at two points, front and rear, by fixing bolts 206 that pass through the fixing surface portion 205a, with the fixing surface portion 205a aligned along the right side of the front upper side plate 58.

[0134] The mounting plate 205 has a horizontal support surface 205b and a vertical support surface 205c that protrude to the right from the front upper side plate 58. The mounting plate 205 is fixed to the upper end of the pipe member constituting the handrail 200 at the horizontal support surface 205b and the vertical support surface 205c. The handrail 200 is fixed to the mounting plate 205 by welding or the like with its upper end opening contacting the horizontal support surface 205b from below and its upper end contacting the vertical support surface 205c from the left. A through-type opening 205d is formed in the front and rear center of the corner between the horizontal support surface 205b and the vertical support surface 205c.

[0135] As shown in Figure 18, a mounting bolt 207 is fixed to the lower end of the handrail portion 200. The mounting bolt 207 is fixed to the handrail portion 200 by welding or the like, with its head 207a closing the opening of the pipe member forming the handrail portion 200, and its threaded portion 207b protruding to the left (to the right in Figure 18). The handrail portion 200 is fastened and fixed to the front lower side portion 45 of the right side wall portion 34 of the cabin 30 by passing the threaded portion 207b of the mounting bolt 207 through it and using a nut 208 that is screwed onto the threaded portion 207b.

[0136] As described above, a mirror stay 210 is provided on the handrail portion 200 located at the front of the right side wall portion 34. The mirror stay 210 is made of a bent plate-shaped member that has a predetermined bent shape when viewed from the front, and is provided so as to protrude forward from a position near the upper end of the handrail portion 200.

[0137] The mirror stay 210 has a bent shape and includes a horizontal upper surface portion 210a, a vertical side surface portion 210b that bends downward at a right angle from the left side of the upper surface portion 210a, a horizontal lower surface portion 210c that bends to the right at a right angle from below the side surface portion 210b, and a vertical hanging lower surface portion 210d that bends downward at a right angle from the left side of the lower surface portion 210c.

[0138] In the mirror stay 210, the upper surface portion 210a and the lower surface portion 210c are opposite each other vertically. The hanging lower surface portion 210d has a roughly right-angled triangular shape with the rear upper side being the right-angled side when viewed from the right side, and has a rear edge portion 210e that runs along the vertical direction. The mirror stay 210 is fixed to the handrail portion 200 by welding or the like with the rear edge portion 210e of the hanging lower surface portion 210d aligned along the front side of the handrail portion 200.

[0139] In this manner, the mirror arm 55 is supported by the mirror stay 210, which is fixed to the handrail portion 200, so as to be rotatable with the vertical direction as the pivot axis. The mirror arm 55 is made up of a rod-shaped member having a predetermined bent shape, and a cylindrical boss portion 55a is provided at the base end of the mirror arm 55, with the vertical direction as the central axis and both the upper and lower ends open.

[0140] The mirror arm 55 is supported by a support bolt 212 so as to be rotatable around a vertical axis relative to the mirror stay 210, with its boss portion 55a interposed between the upper surface portion 210a and the lower surface portion 210c of the mirror stay 210. The support bolt 212 passes through the upper surface portion 210a, the boss portion 55a, and the lower surface portion 210c from above the upper surface portion 210a, and is fixed to the mirror stay 210 by receiving two nuts 213 on the portion that protrudes downward from the lower surface portion 210c. In this support configuration of the mirror arm 55, the base end portion of the mirror arm 55 is positioned between the upper surface portion 210a and the lower surface portion 210c of the mirror stay 210.

[0141] The rearview mirror 53 is supported so as to be able to rotate horizontally relative to the mirror stay 210, with the vertical direction being the axis of rotation, by rotatably supporting a boss portion 55a on a support bolt 212 fixed to the mirror stay 210. A stopper plate 214 that restricts the range of rotation of the rearview mirror 53 is fixed to the rear side of the boss portion 55a by welding or the like. The stopper plate 214 protrudes from the rear side of the boss portion 55a toward the left rear and contacts the right side of the side portion 210b of the mirror stay 210, thereby restricting the rotation of the rearview mirror 53 to the right (left and right outward direction).

[0142] In relation to the support configuration of the rearview mirror 53 described above, the stacked lamp 150B is supported and fixed via the stacked lamp support plate 220. The stacked lamp support plate 220 is a flat plate-shaped member and forms a horizontal surface when fixed to the upper side of the mirror stay 210.

[0143] The stacked lamp support plate 220 is fixed to the mirror stay 210 together with the support bolt 212 by overlapping the left portion of the support plate 220 with the upper surface portion 210a of the mirror stay 210 from above and passing the support bolt 212 through it, sandwiching the support plate 220 between the head of the support bolt 212 and the upper surface portion 210a. The stacked lamp support plate 220 extends to the right from the upper surface portion 210a, forming a horizontal support surface portion on which the stacked lamp 150B is placed and supported.

[0144] The stacked lamp support plate 220 has a hook portion 220b on its rear side that forms an arc-shaped recess 220a on the left side. The stacked lamp support plate 220 engages with the handrail portion 200 in a manner in which the handrail portion 200 is fitted into the recess 220a. The stacked lamp support plate 220 also has an arc-shaped portion 220c at the tip edge of the side that protrudes to the right from the mirror stay 210. In a plan view, the arc-shaped portion 220c has an arc shape with a curvature that follows the circular outer shape of the stacked lamp 150B.

[0145] The stacked lamp 150B is mounted and supported on the stacked lamp support plate 220. The stacked lamp support plate 220 has dimensions that position the entire stacked lamp 150B, which has a circular outer shape in plan view, within the range of its outer shape. The stacked lamp 150B is fixedly supported on the stacked lamp support plate 220, with the upper surface of the stacked lamp support plate 220, which contacts the bottom surface 152, as the mounting surface. The stacked lamp 150B is positioned on the stacked lamp support plate 220 such that, in plan view, the right-hand arc portion substantially coincides with the arc-shaped portion 220c.

[0146] The stack lamp 150B is fastened and fixed to the stack lamp support plate 220 by passing multiple (three) threaded portions 156 protruding from the bottom portion 152 through the stack lamp support plate 220 from above, and screwing the threaded portions 156 into nuts 157 on the underside of the stack lamp support plate 220. Multiple holes 220d are formed in the stack lamp support plate 220 through which the threaded portions 156 pass. In addition, the stack lamp support plate 220 has an opening 220e for passing the connecting cord 155 extending from the bottom portion 152 of the stack lamp 150.

[0147] In the support configuration of the stacked lamp 150B described above, the stacked lamp 150B is positioned at a height such that its upper surface portion 153 is below the height of the upper surface portion 50a of the roof panel 50 in the vertical direction. More specifically, the stacked lamp 150B is positioned such that the entire or substantially entire light-emitting display portion 154 is within the height range of the side portion 50b of the roof panel 50 in the vertical direction.

[0148] Furthermore, the stacked lamp 150B is positioned directly in front of the handrail 200 in the front-to-back direction. In addition, the stacked lamp 150B is positioned near the right side of the right side portion 50b of the roof panel 50 in the left-to-right direction.

[0149] As described above, in the combine harvester 1, stacked lights 150 are provided on both the left and right sides of the cabin 30. On the left side of the combine harvester 1, the area where the stacked lights 150 are visible is covered by stacked light 150A, and on the right side of the combine harvester 1, the area where the stacked lights 150 are visible is covered by stacked light 150B. This configuration, in which the status of the combine harvester 1 is indicated by the display of the two stacked lights 150, makes it possible to understand the display pattern of the light-emitting display unit 154 from any position in all directions around the combine harvester 1, that is, within a 360° range.

[0150] According to the combine harvester 1 of this embodiment, which has the above configuration, the stacked lights 150 used for displaying various statuses of the machine can be positioned in a location that is easily visible from outside the machine and can be firmly supported.

[0151] The stacked lamp 150A is mounted on the auger rest 27 located on the left rear of the cabin 30, supported by the stacked lamp support 160. With this configuration, the stacked lamp 150A can be firmly supported by the support structure of the stacked lamp support 160 on the auger rest 27, where the auger rest body 170 is located in a relatively high part of the combine harvester 1. As a result, the stacked lamp 150A can be positioned in the upper part of the combine harvester 1, and good visibility of the stacked lamp 150A can be obtained from around the combine harvester 1 and from positions far away from the combine harvester 1.

[0152] Furthermore, in a configuration in which the stack lamp 150A is supported by the organest 27, the existing configuration can be used to support the stack lamp 150A, thus simplifying the configuration for supporting the stack lamp 150A.

[0153] Furthermore, the stacked lamp 150A is positioned below the discharge auger 9 in its stowed state, in the vertical direction. With this configuration, the stacked lamp 150A can be positioned in a location that does not interfere with the movement trajectory of the discharge auger 9, thus preventing the stacked lamp 150A from coming into contact with the discharge auger 9. As a result, the display using the stacked lamp 150A can be performed without affecting the operation control of the discharge auger 9.

[0154] Regarding the vertical support position of the stacked lamp 150A, if the support position of the stacked lamp 150A is too high, the stacked lamp 150A is likely to interfere with the movable area of ​​the discharge auger 9. If the support position of the stacked lamp 150A is too low, the stacked lamp 150A will be hidden by the threshing section, etc., reducing its visibility. For this reason, it is preferable to position the stacked lamp 150A as high as possible in the vertical direction, within the limits that do not interfere with the movable area of ​​the discharge auger 9.

[0155] Furthermore, the auger rest 27 supporting the stack lamp 150A is provided in an adjustable height. With this configuration, the height of the stack lamp 150A can be adjusted in conjunction with the height adjustment of the auger rest 27. This effectively prevents the stack lamp 150A from coming into contact with the discharge auger 9 in relation to the operating range of the discharge auger 9, and also allows for good visibility of the stack lamp 150A by positioning it at a higher position.

[0156] Furthermore, with the support configuration of the stacked lamp 150A including the auger rest 27, the stacked lamp 150A is positioned lower than the top of the combine harvester 1, thus providing good handling of the combine harvester 1. In other words, since the stacked lamp 150A does not protrude above the roof panel 50, it is possible to avoid the stacked lamp 150A becoming an obstacle to the movement of the combine harvester 1 when moving the machine during transport or when storing the combine harvester 1 in a warehouse, etc. This provides good handling of the combine harvester 1. In addition, since the stacked lamp 150A does not protrude above the roof panel 50, it is possible to suppress interference between the stacked lamp 150 and other devices such as the discharge auger 9 that moves on the roof panel 50.

[0157] Furthermore, in the combine harvester 1, in addition to the stacked light 150A, a stacked light 150B is provided on the right side of the cabin 30. With this configuration, the two stacked lights 150 make it possible to see the display content of the stacked lights 150 from all directions around the combine harvester 1.

[0158] The stacked lamp 150B is mounted supported by the support structure of the rearview mirror 53 located on the right front of the cabin 30. With this configuration, the stacked lamp 150B can be firmly supported by the support structure of the rearview mirror 53, which is located relatively high on the combine harvester 1. As a result, the stacked lamp 150B can be positioned on the upper part of the combine harvester 1, and good visibility of the stacked lamp 150B can be obtained from around the combine harvester 1 and from positions far away from the combine harvester 1.

[0159] Furthermore, in a configuration in which the stacked lamp 150B is supported by the support configuration of the rearview mirror 53, the existing configuration can be used to support the stacked lamp 150B, thus simplifying the configuration for supporting the stacked lamp 150B. In particular, in this embodiment, the rearview mirror 53 is provided via a mirror stay 210 to the handrail portion 200 provided on the front right side of the cabin 30, and the stacked lamp 150B is supported in an upright position via a stacked lamp support plate 220 to the mirror stay 210. With such a configuration, the existing configuration can be effectively utilized, and the stacked lamp 150B can be firmly supported.

[0160] Regarding the support height of the stacked lamp 150B, it is preferable to set it at a height such that the stacked lamp 150B does not protrude above the roof panel 50. This prevents the stacked lamp 150B from becoming an obstacle to the movement of the combine harvester 1 during transportation or storage, and ensures good handling of the combine harvester 1.

[0161] Furthermore, in a configuration where the rearview mirror 53 supports the mirror body 54 in a hanging manner at the tip of the mirror arm 55, the stacked lamp 150B is provided above the base end of the mirror arm 55 (see Figure 5). With this configuration, the stacked lamp 150B can be provided without obstructing the view of the mirror body 54 from the driver's compartment 12 inside the cabin 30.

[0162] [Second Embodiment] A second embodiment of the present invention will be described with reference to Figures 19 to 23. In each embodiment of the present invention described below, the same names or reference numerals will be used for components that are common to or correspond to those in the first embodiment, and explanations of redundant content will be omitted as appropriate.

[0163] This embodiment is a modified example of the arrangement and support configuration of the stacked lamp 150B located on the right side of the cabin 30. In this embodiment, the stacked lamp 150B is provided on the mirror arm 55 of the rearview mirror 53 via a stacked lamp support portion 250.

[0164] The mirror arm 55 has an arm portion 55b that extends horizontally approximately forward from its base end, which is the support portion for the mirror stay 210, and a hanging portion 55c that is formed to follow the vertical direction from the front side of the arm portion 55b through a curved portion downward. The mirror body 54 is supported below the hanging portion 55c.

[0165] The stacked lamp support section 250 includes a mounting bracket 251 fixed to the mirror arm 55 and a support stay 252 fixed to the mounting bracket 251.

[0166] The mounting bracket 251 is a bent plate-like member that has a roughly U-shape with the rear side open when viewed from the side, and has upper and lower horizontal support surfaces 251a that face each other in the vertical direction, and a vertical fixing surface 251b that connects them. The mounting bracket 251 is installed on the front side of the hanging portion 55c of the mirror arm 55, with the tip (rear end) of the support surface 251a fixed to the hanging portion 55c by welding or the like. The mounting bracket 251 has the fixing surface 251b positioned in front of the hanging portion 55c of the mirror arm 55 (to the right in Figure 20), with the upper and lower support surfaces 251a and a predetermined distance from the hanging portion 55c.

[0167] The support stay 252 is made of a bent plate-shaped member and has a vertically extending support column 253 and a support base 254 provided above the support column 253. The support stay 252, formed by the support column 253 and the support base 254, has a roughly inverted L-shape when viewed from the side (see Figure 20).

[0168] The support column 253 is composed of a bent plate-like member that forms a roughly U-shape in plan view with the rear side open, and has a front portion 253a with the front-to-back direction as the plate thickness direction, and left and right side portions 253b that are bent toward the rear from both left and right edges of the front portion 253a. At the upper end of the support column 253, the left and right side portions 253b have inclined portions 253c in which the dimension in the front-to-back direction (width dimension of the side portion 253b) gradually increases from the bottom to the top.

[0169] The support base portion 254 protrudes horizontally backward from the upper end of the support column portion 253 and serves as the portion on which the stacked lamp 150B is placed and supported. The support base portion 254 has a roughly rectangular outer shape in plan view and includes a support surface portion 254a that forms a horizontal mounting support surface for the stacked lamp 150B, and bent surface portions 254b that are bent at a right angle downward from the support surface portion 254a on both the left and right sides of the support surface portion 254a.

[0170] In this configuration, the upper end of the member forming the support column 253 is fitted between the left and right bent surfaces 254b at the front of the member forming the support base 254, and the two members are fixed to each other by welding or the like, forming a support stay 252 which is an integral member.

[0171] The support stay 252 is attached to the mirror arm 55 by fixing the support column 253 to the mounting bracket 251. In detail, the front portion 253a of the support column 253 of the support stay 252 is overlapped from the front with the fixing surface 251b of the mounting bracket 251, and fastened to the mounting bracket 251 at two points, top and bottom, with fixing bolts 256 and nuts 257. For this reason, holes (holes 255 in the case of the support column 253) are formed in the fixing surface 251b of the mounting bracket 251 and the front portion 253a of the support column 253, respectively, through which the fixing bolts 256 pass. In the example shown in Figure 20, the upper part of the support column 253 of the support stay 252 is fixed to the mounting bracket 251.

[0172] In the support base portion 254, the stacked lamp 150B is placed and supported on the support surface portion 254a. The support surface portion 254a has dimensions that position the entire stacked lamp 150B, which has a circular outer shape in plan view, within the range of its outer shape. The stacked lamp 150B is fixedly supported on the support surface portion 254a, with the upper surface of the support surface portion 254a, which contacts the bottom surface portion 152, serving as the mounting surface.

[0173] The stack lamp 150B is fastened and fixed to the support surface 254a of the support base 254 by passing multiple (three) threaded portions 156 through the support surface 254a of the support base 254 from above, and screwing the threaded portions 156 into nuts 157 on the underside of the support surface 254a. Multiple holes 254c are formed in the support surface 254a through which the threaded portions 156 pass (see Figure 22). In addition, an opening 254d is formed in the support surface 254a for passing a connecting cord 155 that extends from the bottom surface 152 of the stack lamp 150B (see Figure 22).

[0174] In the support configuration of the stacked lamp 150B described above, the stacked lamp 150B is positioned at a height such that its upper surface portion 153 is at approximately the same height as the upper surface portion 50a of the roof panel 50 (see Figure 21). Therefore, the stacked lamp 150B is positioned such that, in the vertical direction, the entire or substantially entire light-emitting display portion 154 is within the height range of the side portion 50b of the roof panel 50.

[0175] Furthermore, the stacked lamp 150B is positioned in approximately the same location as the mirror body 54 of the rearview mirror 53 in the front-to-back direction (see Figure 19). In addition, the stacked lamp 150B is positioned in the left-to-right direction near the right upper front corner of the right front window section 49 that forms the right side wall section 34 of the cabin 30 (see Figure 19).

[0176] In the support configuration of the stacked lamp 150B according to this embodiment, the support stay 252 is provided with respect to the mounting bracket 251 in a height-adjustable manner. The height of the support stay 252 is changed by changing the fixing position of the support column portion 253 with respect to the mounting bracket 251.

[0177] Specifically, in the front portion 253a of the support column 253, which is fixed by fixing bolts 256 at two locations, upper and lower, two sets of holes 255 are provided, one at the top and one at the bottom, through which the fixing bolts 256 pass. In other words, the support column 253 is provided with two first holes 255A, one at the top and one at the bottom, which fix the support stay 252 to the mounting bracket 251 at a first height position, and two second holes 255B, one at the top and one at the bottom, which fix the support stay 252 to the mounting bracket 251 at a position higher than the first height position (see Figure 21). The first holes 255A are formed in the upper part of the support column 253, and the second holes 255B are formed in the lower part of the support column 253.

[0178] Thus, the support stay 252 is provided so as to be adjustable in the vertical direction by having a first hole 255A and a second hole 255B in the support column portion 253. In other words, the fixing position of the support stay 252 to the mounting bracket 251 fixed to the mirror arm 55 can be adjusted in two stages: a low position using one pair of first holes 255A and a high position using one pair of second holes 255B.

[0179] By adjusting the height of the support stay 252, the height position of the stacked lamp 150B supported on the support stay 252 is adjusted. In other words, the height of the stacked lamp 150B changes integrally with the height of the support stay 252 as the height of the support stay 252 is adjusted. Therefore, the stacked lamp 150B is provided with two height adjustment levels: a low position and a high position.

[0180] In Figure 19, the state in which the support stay 252 and the stacked lamp 150B are positioned at a high position is shown by the dashed line. When the stacked lamp 150B is supported at a high position, the entire or substantially entire light-emitting display unit 154 is positioned above the upper surface 50a of the roof panel 50.

[0181] The stacked lamp 150B is mounted supported by the mirror arm 55 of the rearview mirror 53 located on the right front of the cabin 30. This configuration allows the stacked lamp 150B to be firmly supported by the rearview mirror 53, which is located relatively high on the combine harvester 1. As a result, the stacked lamp 150B can be positioned on the upper part of the combine harvester 1, and good visibility of the stacked lamp 150B can be obtained from around the combine harvester 1 and from positions far away from the combine harvester 1.

[0182] Furthermore, in the configuration in which the stacked lamp 150B is supported by the rearview mirror 53, the existing configuration can be used to support the stacked lamp 150B, thus simplifying the configuration for supporting the stacked lamp 150B. In particular, in this embodiment, the stacked lamp 150B is supported in an upright position via a support stay 252 on a mirror arm 55 which is made of a metal rod-shaped member. With such a configuration, the existing configuration can be effectively utilized, and the stacked lamp 150B can be firmly supported.

[0183] Furthermore, in a configuration in which a stacked lamp 150B is attached to a rearview mirror 53 that is mounted on a mirror stay 210 provided on the handrail section 200 so as to be able to rotate horizontally by support bolts 212, the stacked lamp 150B can be stored by using the horizontal rotation of the rearview mirror 53.

[0184] Specifically, as shown in Figure 22, by rotating the rearview mirror 53 inward to the left and right around the pivot axis C1 by the support bolt 212 (see arrow C2), the rearview mirror 53 is retracted, and consequently, the stacked lamp 150B is also retracted. By being able to retract the stacked lamp 150B together with the rearview mirror 53, it is possible to avoid the stacked lamp 150B becoming an obstacle to the movement of the combine harvester 1 during transportation or storage, for example, and good handling of the combine harvester 1 can be obtained.

[0185] Furthermore, the support stay 252 that supports the stack lamp 150B is provided in a height-adjustable manner. With this configuration, the height of the stack lamp 150B can be adjusted. This makes it possible to avoid the stack lamp 150B coming into contact with the discharge auger 9 in relation to the operating range of the discharge auger 9, and by positioning the stack lamp 150B at a higher position, good visibility of the stack lamp 150B can be obtained.

[0186] In particular, the high position for supporting the stacked lamp 150B can be set to a height where the entire light-emitting display unit 154 is located above the upper surface 50a of the roof panel 50. With such a configuration, the stacked lamp 150A on the left side of the cabin 30 can be omitted, and the display pattern of the light-emitting display unit 154 can be understood from all directions around the combine harvester 1 using only the stacked lamp 150B on the right side.

[0187] On the other hand, the support height of the stacked lamp 150B can be configured such that the stacked lamp 150B does not protrude above the roof panel 50. With such a configuration, for example, the stacked lamp 150B can avoid becoming an obstacle to the movement of the combine harvester 1 during transport or storage, and good handling of the combine harvester 1 can be obtained.

[0188] Furthermore, the stacked lamp 150B is installed above the hanging portion 55c of the mirror arm 55, which is located above the mirror body 54. With this configuration, the stacked lamp 150B can be installed without obstructing the view of the mirror body 54 from the driver's compartment 12 inside the cabin 30.

[0189] [Third Embodiment] A third embodiment of the present invention will be described with reference to Figures 24 and 25. The combine harvester according to this embodiment is equipped with one stacked lamp 150C located on the left side of the cabin 30 as a stacked lamp 150. The stacked lamp 150C is supported by a stacked lamp support part 360, which is a support part provided on the auger rest 27. In other words, the stacked lamp 150C is supported by the auger rest 27 via the stacked lamp support part 360. In the vertical direction, the stacked lamp 150C is located above the discharge auger 9 in its stowed state.

[0190] As shown in Figures 24 and 25, the stack lamp support section 360 is attached to the auger rest support column 171 of the auger rest 27. The stack lamp support section 360 supports the stack lamp 150C to the left and above the discharge auger 9 in its stored state. The stack lamp support section 360 has a horizontal support base section 361 on which the stack lamp 150C is placed and supported, and a support stay section 362 that supports the support base section 361 relative to the auger rest support column 171. Note that the support stay section 362 is not shown in Figure 25.

[0191] The support base 361 is located near the left side of the auger rest main body 170 (see Figure 25). As a result, the stacked lamp 150C supported on the support base 361 is located near the left side of the support portion of the auger body 9a of the discharge auger 9 in its stored state, which is supported by the auger rest main body 170. The support base 361 is located in approximately the same position as the auger rest main body 170 in the front-rear direction.

[0192] The support base 361 is positioned higher than the upper end of the auger body 9a of the discharge auger 9 in the vertical direction (see Figure 24). As a result, the stacked lamp 150C supported on the support base 361 is positioned above the upper end of the auger body 9a in its stored state.

[0193] The support base 361 has a roughly rectangular outer shape in plan view and includes a support surface 361a that forms a horizontal mounting support surface for the stacked lamp 150C, and bent surface 361b that are bent at a right angle downward from the support surface 361a on both the front and rear sides. The support surface 361a is provided inclined in the front, rear, left and right directions in plan view so that a pair of opposing sides of its rectangular outer shape in plan view are aligned with the extension direction of the auger body 9a in its stored state.

[0194] The support base portion 361 has the same shape as the support base portion 254 according to the second embodiment, and the stack lamp 150C is placed and supported on the support surface portion 361a. The stack lamp 150C is fastened and fixed to the support surface portion 361a of the support base portion 361 by passing multiple (3) screw portions through the support surface portion 361a of the support base portion 361 from above and screwing them into nuts. The support surface portion 361a has multiple holes through which the screw portions pass, and an opening for passing a connecting cord 155 that extends from the bottom surface portion 152 of the stack lamp 150C.

[0195] The support stay portion 362 has a horizontally extending arm portion 363 and a column portion 364 that extends vertically in a rear view, and is configured to form a roughly L-shape in a rear view by the arm portion 363 and the column portion 364 (see Figure 24). The support stay portion 362 is constructed, for example, by connecting a plate-shaped member that forms the arm portion 363 and a column-shaped member that forms the column portion 364 to each other. The support stay portion 362 may also be a portion made of a roughly L-shaped integrated member.

[0196] The support stay portion 362 is provided with the base end (right side) of the arm portion 363 fixed to the auger rest support column portion 171 by welding or fasteners such as bolts. The arm portion 363 extends to the left from the fixing portion to the auger rest support column portion 171. The arm portion 363 extends until its tip is in a position that does not overlap the auger rest main body portion 170 or the stored auger main body portion 9a in a plan view. The support column portion 364 extends upward from the tip of the arm portion 363, with its tip (upper end) positioned above the stored auger main body portion 9a. The support base portion 361 is fixed to the upper end of the support column portion 364 by welding or fasteners such as bolts.

[0197] In the support configuration of the stacked lamp 150C described above, the stacked lamp 150C is installed so that the display of the light-emitting display unit 154 can be understood from any position within a 360° range, that is, from all directions around the combine harvester 1, in order to inform the status of the combine harvester 1 by its display. In this regard, the stacked lamp 150C is installed so that, in the vertical direction, at least the entire light-emitting display unit 154 is positioned above the upper surface portion 50a of the roof panel 50 of the cabin 30.

[0198] Furthermore, as shown in Figure 25, the stacked lamp 150C is positioned in approximately the same location as the rear end of the roof panel 50 in the front-to-back direction. In addition, the stacked lamp 150C is positioned near the left side of the organest main body 170 in the left-to-right direction.

[0199] According to the combine harvester 1 of this embodiment, the stacked lamp 150C, which is used to display various conditions of the machine, can be positioned in a location that is easily visible from outside the machine and can be firmly supported.

[0200] The stacked lamp 150C is installed supported by the stacked lamp support section 360 on the organist rest 27. With this configuration, the stacked lamp 150C can be firmly supported on the organist rest 27 by the support structure of the stacked lamp support section 360. As a result, the stacked lamp 150C can be positioned at the top of the combine harvester 1, and good visibility of the stacked lamp 150C can be obtained from around the combine harvester 1 and from a distance away from the combine harvester 1. Furthermore, since the existing organist rest 27 can be used to support the stacked lamp 150C, the configuration for supporting the stacked lamp 150C can be simplified.

[0201] Furthermore, the stacked lamp 150C is positioned above the discharge auger 9 in its stowed state in the vertical direction. In this embodiment, the stacked lamp 150C is positioned such that the entire light-emitting display unit 154 is above the upper surface 50a of the roof panel 50 in the vertical direction. With this configuration, one stacked lamp 150C makes it possible to understand the display mode of the light-emitting display unit 154 from all directions around the combine 1. As a result, the number of stacked lamps 150 is reduced compared to a configuration with two stacked lamps 150, thereby reducing costs.

[0202] In the combine harvester 1, the main operation of the discharge auger 9 is upward rotation and rotation to the right from the stored position by the auger rest 27. That is, in a plan view, the main operating range of the discharge auger 9 is the operating range to the right (clockwise) from the position in the stored position. Therefore, the support configuration of the stacked lamp 150C according to this embodiment is provided to the left of the auger rest 27 and the discharge auger 9 in the stored position. Accordingly, in this embodiment, from the viewpoint of avoiding interference of the discharge auger 9 with the stacked lamp 150C and the stacked lamp support part 360, for example, the operation control of the discharge auger 9 is performed to limit the operating range of the discharge auger 9 to a range above and to the right of the stored position by the auger rest 27.

[0203] In this embodiment, for example, the support column 364 constituting the support stay 362 is made into a divided structure with multiple members in the vertical direction, and multiple fixing positions between the members are provided in the vertical direction, thereby allowing the stacked lamp 150C to be installed in an adjustable height. With such a configuration, by positioning the stacked lamp 150C at a height lower than the auger rest main body 170, it is possible to avoid the stacked lamp 150C coming into contact with the discharge auger 9. Also, by positioning the stacked lamp 150C at a height higher than the discharge auger 9 in its stored state, good visibility of the stacked lamp 150C can be obtained. Furthermore, regarding the height of the stacked lamp 150C, by positioning it at a height where it does not protrude above the roof panel 50, it is possible to avoid the stacked lamp 150C becoming an obstacle to the movement of the combine 1 during transport or storage, for example, and good handling of the combine 1 can be obtained.
