Description

harvester

[0001] The present invention relates to a harvester.

[0002] For example, a harvester (referred to as a "combine" in the publication) disclosed in Japanese Patent Application Laid-Open No. 2020-103055 includes a receiver (referred to as a "GPS antenna unit" in the publication) that receives signals from satellites and a mounting member (referred to as a "stay" in the publication) to which the receiver is attached. The mounting member is configured to be changeable between a usage state (referred to as a "usage position" in the publication) in which the receiver is used and a storage state (referred to as a "storage position" in the publication) that is lower than the usage state.

[0003] Japanese Patent Application Publication No. 2020-103055

[0004] When the receiving device receives a signal from a satellite, the mounting member is held in the in-use state to improve positioning accuracy. However, since vibrations tend to increase when the harvester is traveling, it is important that the mounting member be firmly held in the in-use state. However, if the mounting member is held too firmly in the in-use state, for example, a worker may find it troublesome to release the mounting member when changing the state from the in-use state to the stored state. For this reason, it is also important that the mounting member be easily held in the in-use state by the worker.

[0005] An object of the present invention is to provide a harvester that can smoothly change the state of a mounting member to which a receiving device is attached.

[0006] The harvester of the present invention comprises a driving section having a driver's seat, a receiving device that receives signals from a satellite, a mounting member to which the receiving device is attached, and a support member that extends upward from the driving section and supports the mounting member, and the mounting member is configured to be changeable between a usage state in which the receiving device is used and a storage state in which the receiving device is stored at a lower position than the usage state, and is characterized in that it comprises a locking mechanism that can be changed between a fixed state that fixes the mounting member to the usage state and a released state that releases the mounting member from being fixed to the usage state, and a holding member that holds the locking mechanism in the released state.

[0007] According to the present invention, a locking mechanism is provided to fix the mounting member in the use state. Therefore, the mounting member is held firmly in the use state compared to a configuration without a locking mechanism. Furthermore, the locking mechanism is configured to be changeable between a fixed state and an unlocked state, and the unlocked state of the locking mechanism can be maintained by a holding member. Therefore, for example, when an operator or the like changes the state of the mounting member from the use state to the storage state, the operator or the like can simply hold the locking mechanism in the unlocked state with the holding member, and then change the state of the mounting member to the storage state without any further action. This allows the operator or the like to easily change the state of the mounting member. As a result, a harvester is realized that allows the state of the mounting member to which the receiving device is attached to be smoothly changed.

[0008] In the present invention, it is preferable that a positioning mechanism be provided that is configured separately from the locking mechanism and that positions the mounting member in the use state.

[0009] With this configuration, even if the locking mechanism is not in the fixed state, the mounting member is positioned in the usage state by a positioning mechanism configured separately from the locking mechanism, which makes it possible to temporarily fasten the mounting member in the usage state.

[0010] In the present invention, it is preferable that the positioning mechanism determines the position of the mounting member in the stored state.

[0011] With this configuration, the mounting member is positioned in the stored state by the positioning mechanism, which allows the mounting member to be temporarily fixed in the stored state.

[0012] In the present invention, the mounting member is configured to swing around a swing axis extending horizontally, so that its state can be changed between the use state and the storage state, and it is preferable that the locking mechanism and the positioning mechanism are arranged on one side and the other side of the mounting member in the swing axis direction.

[0013] According to this configuration, the locking mechanism and the positioning mechanism are arranged on one side and the other side of the mounting member, respectively, so that the entire mechanism is balanced along the direction of the swing axis.

[0014] In the present invention, the mounting member is configured to swing around a swing axis extending horizontally, so as to be able to change its state between the use state and the storage state, and it is preferable that the support member has a first prevention portion that prevents the mounting member from swinging around the swing axis beyond the position of the storage state when the mounting member abuts against it.

[0015] With this configuration, the first blocking portion can firmly support the mounting member in the stored state.

[0016] In the present invention, it is preferable that the mounting member has an abutment portion that can abut against the first blocking portion, and the abutment portion is made of an elastic body.

[0017] With this configuration, the mounting member is less likely to be subjected to impacts in the stored state, and the mounting member is prevented from being damaged.

[0018] In the present invention, it is preferable that the contact portion is configured so that its position is adjustable.

[0019] This configuration makes it possible to adjust the position of the receiving device when the mounting member is in the stored state.

[0020] In the present invention, it is preferable that the support member has a second preventing portion that prevents the mounting member from swinging around the swing axis beyond the position in the use state when the mounting member abuts against the second preventing portion.

[0021] With this configuration, the mounting member is in the usable state when the mounting member and the second blocking portion abut against each other. Therefore, when the mounting member and the second blocking portion abut against each other, the mounting member is maintained in the usable state, and it is easy to change the locking mechanism from the released state to the fixed state.

[0022] In the present invention, it is preferable that the second blocking portion is made of an elastic body.

[0023] This configuration makes the mounting member less susceptible to impacts when in use, and prevents the mounting member from being damaged.

[0024] In the present invention, it is preferable that the abutment portion is configured to be able to abut against the second blocking portion, and that the abutment portion abutting against the second blocking portion prevents the mounting member from swinging around the swing axis beyond the position in the use state.

[0025] With this configuration, the mounting member is in a usable state when the abutting portion and the second blocking portion abut. Therefore, when the abutting portion and the second blocking portion abut, the mounting member is maintained in a usable state, making it easy to change the locking mechanism from the released state to the locked state. In addition, the abutting portion is interposed between the mounting member and the second blocking portion, preventing damage to the mounting member.

[0026] In the present invention, it is preferable that the mounting member is configured to swing around a swing axis extending horizontally, so that it can be changed between the use state and the storage state, and that it is provided with a handle that is attached to the mounting member and is used to swing the mounting member.

[0027] This configuration improves the operability of the mounting member compared to a configuration without a handle.

[0028] In the present invention, it is preferable that the handle be attached to the attachment member at a location close to the pivot axis.

[0029] With this configuration, compared to a configuration in which the handle is attached to a location closer to the free end of the attachment member, an operator or the like can more easily operate the handle from the driver's section or the like.

[0030] In the present invention, it is preferable that the mounting member is arranged on one side of the driver's seat in the left-right direction of the vehicle body, and the handle is attached to the side of the mounting member on the driver's seat side in the left-right direction of the vehicle body.

[0031] With this configuration, an operator or the like can easily operate the steering wheel from the driver's seat.

[0032] In the present invention, it is preferable that the mounting member is configured to be able to be fixed in the stored state.

[0033] With this configuration, the mounting member is securely maintained in a stored state, thereby reducing the risk of the mounting member or the receiving device being accidentally damaged while the harvester is in storage.

[0035] The harvester of this embodiment will be described below using a head-feeding combine as an example.

[0036] FIG. 1 is a left side view of a combine harvester, and FIG. 2 is a plan view of the combine harvester. For ease of understanding, in this embodiment, unless otherwise specified, "front" (the direction of arrow "F" in FIG. 1 ) refers to the front in the longitudinal direction (travel direction) of the machine, and "rear" (the direction of arrow "B" in FIG. 1 ) refers to the rear in the longitudinal direction (travel direction) of the machine. Furthermore, "up" (the direction of arrow "U" in FIG. 1 ) and "down" (the direction of arrow "D" in FIG. 1 ) refer to a positional relationship in the vertical direction (perpendicular to the horizontal plane) and indicate a relationship at ground level. Furthermore, the left-right direction or lateral direction refers to a transverse direction (width direction) of the machine, which is perpendicular to the longitudinal direction of the machine. That is, "left" (the direction of arrow "L" in FIG. 2 ) and "right" (the direction of arrow "R" in FIG. 2 ) refer to the leftward and rightward directions of the machine, respectively. This also applies to FIG. 3 and subsequent figures.

[0037] [Overall Description of the Combine Harvester] As shown in FIG. 1 , the traveling body 1 of the combine harvester includes a body frame 2, which is constructed by connecting multiple steel materials such as square pipes. A pair of left and right crawler-type traveling devices 3 are mounted on the lower part of the body frame 2. A driving unit 5 is provided on the right side of the front of the traveling body 1. A driver rides in the driving unit 5. Note that since the combine harvester (harvester) of this embodiment is configured to be capable of automatic traveling and automatic steering, the driver riding in the driving unit 5 includes both a driver who drives the combine harvester and a driver who does not drive the combine harvester. An engine E is located below the driving unit 5. The driving unit 5 is not covered by a cabin and is open to the outside.

[0038] A reaping unit 4 is provided at the front of the traveling body 1 and is capable of being raised and lowered. The reaping unit 4 has multiple dividers 4a and multiple raising devices 4b. The reaping unit 4 reaps multiple rows of planted rice or wheat stalks (crops) in front of the traveling body 1 while raising them with the raising devices 4b, and transports the reaped stalks toward the rear of the machine body. A threshing device 6 and a grain tank 8 are supported side-by-side at the rear of the machine body frame 2. The threshing device 6 is located behind the reaping unit 4, and the grain tank 8 is located behind the driving unit 5. A feed chain 7 is provided on the left side of the threshing device 6, and the feed chain 7 clamps and transports the reaped stalks reaped by the reaping unit 4 toward the rear. The threshing device 6 threshes the reaped stalks and then separates them into grains and dust. The grain tank 8 stores the grains that have been threshed and transported from the threshing device 6. A transport device 9 that removes the grains from the grain tank 8 is connected to the rear of the grain tank 8.

[0039] The conveying device 9 is equipped with a vertical conveying section 9A and a horizontal conveying section 9B. The vertical conveying section 9A is connected to the rear lower section of the grain tank 8 and vertically conveys the grains stored in the grain tank 8. The horizontal conveying section 9B is connected to the upper end of the vertical conveying section 9A and feeds the grains from the vertical conveying section 9A horizontally. A discharge opening 9C is provided at the downstream end in the conveying direction of the horizontal conveying section 9B. The horizontal conveying section 9B conveys the grains from the vertical conveying section 9A to the discharge opening 9C and discharges them from the machine outside through the discharge opening 9C.

[0040] The horizontal conveying section 9B is configured to be able to move up and down and to rotate left and right. As shown in Figures 1 and 2, when the conveying device 9 is not in use, the horizontal conveying section 9B is positioned above the threshing device 6 and the grain tank 8, and extends forward and backward while spanning the center of the machine body in a plan view. The state of the horizontal conveying section 9B in this state is referred to as the "storage state." The position of the horizontal conveying section 9B in this state is referred to as the "home position."

[0041] When the conveying device 9 is in use, the lateral conveying section 9B can extend from its stored state in the home position to the outside of the machine body to discharge grain. Here, "outside of the machine body" means to the left of the left side of the threshing device 6 (lateral outside of the machine body), to the right of the right side of the grain tank 8 (lateral outside of the machine body), and behind the rear ends of the threshing device 6 and the grain tank 8. In other words, when the conveying device 9 is in use, the lateral conveying section 9B extends to the left or right side or rearward from the traveling machine body 1 to discharge grain stored in the grain tank 8.

[0042] The combine harvester of this embodiment is equipped with a satellite positioning receiver 20. The receiver 20 receives signals from a GNSS (Global Navigation Satellite System, such as GPS, GLONASS, Galileo, QZSS, and BeiDou) from a navigation satellite (not shown) to acquire the vehicle's position. The receiver 20 is located on the left side of the vehicle body (one side in the left-right direction) with respect to the lateral center of the driver's unit 5.

[0043] [Driver's Unit] The driver's unit 5 is provided in a state biased toward the right side of the aircraft body relative to the center of the aircraft body. As shown in Figures 1 to 4, the driver's unit 5 is provided with a driver's seat 11, a front panel 12 located in front of the driver's seat 11, and a side panel 13 located to the left of the driver's seat 11. The driver's seat 11 is provided in the central region of the driver's unit 5. A driver sits in the driver's seat 11. A floor section 15 (Figure 3) is provided between the front panel 12 and the driver's seat 11 in the fore-and-aft direction. An access step 14 is provided to the right of the driver's seat 11 and the floor section 15. The side panel 13 is provided on the side of the driver's unit 5 opposite the side where the access step 14 is located.

[0044] The front panel 12 is provided with a steering lever 16 and a meter panel (not shown). The steering lever 16 is an operating tool for driving operations and is provided at the right end of the front panel 12, located in front of the driver's seat 11. A driver sitting in the driver's section 5 can steer the traveling device 3 by operating the steering lever 16. The driver can also raise and lower the reaping section 4 by operating the steering lever 16. In other words, the steering lever 16 accepts steering operations and work operations. The meter panel (not shown) displays, for example, the traveling speed, engine RPM, remaining fuel, etc.

[0045] The side panel 13 is provided with a main speed change control lever 18 and other components. The main speed change control lever 18 is located at the front of the side panel 13. The main speed change control lever 18 is configured as a lever that can be operated to swing back and forth. A driver in the driver's section 5 can change speeds in a main transmission (not shown) by operating the main speed change control lever 18.

[0046] A box-shaped rear box 40 is provided behind the driver's seat 11. The rear box 40 protrudes above the seat surface of the driver's seat 11. The upper surface of the rear box 40 is located at a height corresponding to the upper part of the backrest of the driver's seat 11. Although not described in detail, the rear box 40 houses an air cleaner for intake to the engine E, an electronic control unit (ECU), and the like.

[0047] A canopy 41 is provided above the driving section 5. The canopy 41 covers the driving section 5 to provide protection from the sun and rain.

[0048] [Regarding the Support Structure of the Receiver] In this embodiment, the receiver 20 is supported by a mounting member 25, and the receiver 20 and the mounting member 25 are supported so as to be swingable on the support member 21. As shown in Fig. 2, the receiver 20 and the mounting member 25 are disposed on the left side of the aircraft body relative to the driver's seat 11. As shown in Figs. 3 and 4, the support member 21 that supports the receiver 20 and the mounting member 25 includes front and rear frame portions 22, vertical frame portions 23, and horizontal frame portions 24.

[0049] The front and rear frame sections 22 extend in the front-to-rear direction in plan and side views of the aircraft. The vertical frame sections 23 extend in the up-down direction. Furthermore, the vertical frame sections 23 support the mounting members 25 and fulcrum members 26 at their upper parts. The front and rear frame sections 22 are connected to the upper parts of the vertical frame sections 23 and extend horizontally or approximately horizontally from the vertical frame sections 23. In other words, the front ends of the front and rear frame sections 22 are connected to the upper ends of the vertical frame sections 23. The horizontal frame sections 24 extend horizontally in the plan view of the aircraft. The horizontal frame sections 24 are connected to the front lower parts of the vertical frame sections 23.

[0050] The support member 21 is formed into an L-shape in a plan view by front and rear frame portions 22, vertical frame portions 23, and horizontal frame portions 24. The support member 21 is also formed into a gate-like shape by the front and rear frame portions 22 and the vertical frame portions 23 in a side view of the aircraft.

[0051] 3, a fulcrum member 26 is connected and fixed by a bolt to the connecting portion between the front-rear frame portion 22 and the vertical frame portion 23. A mounting member 25 is pivotally supported on the fulcrum member 26. The receiving device 20 is attached to the free end of the mounting member 25. In other words, the mounting member 25 is supported by the front-rear frame portion 22 and the vertical frame portion 23 via the fulcrum member 26, and also connects and supports the receiving device 20.

[0052] The state in which the mounting member 25 is swung upward is shown by a solid line in Fig. 1, and this state of the mounting member 25 corresponds to the "usage state" set forth in the claims. The state in which the mounting member 25 is swung downward is shown by a dashed line in Fig. 1. This state of the mounting member 25 corresponds to the "storage state" set forth in the claims. In other words, the mounting member 25 is configured to swing about the horizontally extending swing axis X1, so that it can be changed between a usage state in which the receiving device 20 is used and a storage state in which the receiving device 20 is stored at a lower position than in the usage state.

[0053] When the mounting member 25 is changed to the use state, the position of the receiving device 20 is less susceptible to the effects of multipath and the like compared to when the mounting member 25 is in the stored state, improving the positioning accuracy of the receiving device 20 during harvesting work. Furthermore, when the mounting member 25 is changed to the stored state, interference between the ceiling and the receiving device 20 is avoided even if the ceiling of the storage shed where the combine is kept is low.

[0054] Whether the mounting member 25 is in the use state or the stored state, the receiving device 20 is located forward of the driving unit 5, overlaps with the reaping unit 4 in a plan view, and is located at the center of the left-right width of the reaping unit 4. As shown in Figures 1 and 2, the receiving device 20 is located within the range of the front-to-rear width W between the tip of the divider 4a and the rear of the lifting device 4b (the upper end of the lifting device 4b in Figures 1 and 2). Whether the mounting member 25 is in the use state or the stored state, the receiving device 20 is located within the range of the front-to-rear width W.

[0055] The receiving device 20 is located on the left side of the vehicle body relative to the driving unit 5. Furthermore, when the mounting member 25 is in use, the receiving device 20 is located almost entirely in front of the canopy 41. Note that when the mounting member 25 is in use, the receiving device 20 may be located entirely in front of the canopy 41. Furthermore, when the mounting member 25 is in use, the receiving device 20 does not overlap with either the canopy 41 or the horizontal conveying unit 9B in the stored state in a plan view of the vehicle body.

[0056] 1, when the attachment member 25 is in the use state, the receiving device 20 is located at a position higher than the upper end of the horizontal conveying section 9B in the stored state. Also, when the attachment member 25 is in the stored state, the entire receiving device 20 is located below the upper end of the horizontal conveying section 9B of the conveying device 9 in the stored state, and is located further rearward of the machine body than the front end of the horizontal conveying section 9B in the stored state. Alternatively, when the attachment member 25 is in the stored state, the upper end of the receiving device 20 may be located at the same or approximately the same height as the upper end of the horizontal conveying section 9B in the stored state.

[0057] When the mounting member 25 is in the stored state, the receiving device 20 is located at the same or approximately the same height as the upper end of the support member 21 (specifically, the upper end of the front and rear frame portions 22). Note that the position (height adjustment) of the receiving device 20 during storage can be adjusted by adjusting the position of the abutment portion 25F (see FIG. 5, etc.) with a bolt.

[0058] The front-rear frame section 22 and the vertical frame section 23 are supported on the left side of the driver's section 5. In other words, the driver's section 5 is provided in a state where it is biased to the right side of the vehicle body with respect to the center of the vehicle body, and the front-rear frame section 22 is supported on the end of the driver's section 5 on the left-right center side of the vehicle body. The front portions of the front-rear frame section 22 extend horizontally and in the front-rear direction. In a side view of the vehicle body, the front portions of the front-rear frame section 22 overlap with the lateral conveying section 9B in the stored state (see FIG. 1).

[0059] The front and rear frame sections 22 have a rod section 22a extending in the front-rear direction, a rectangular plate member 22b at the front end, and a rectangular plate member 22c at the rear end. The rectangular plate member 22b is welded to the front end of the rod section 22a. The rectangular plate member 22c is welded to the rear end of the rod section 22a. The middle portion of the rod section 22a between the front and rear ends is bent. The bottom surface of the rectangular plate member 22c is connected to the upper surface of the rear box 40 with bolts. In other words, the front and rear frame sections 22 are supported by the upper surface of the rear box 40. As a result, the rear portion of the rod section 22a is tilted downward toward the rear. In other words, the rod section 22a extends horizontally or approximately horizontally from the vertical frame section 23 and is tilted downward toward the rear at its rear. In other words, the rear portion of the rod section 22a is erected in a forward-leaning position on the left side of the rear of the driver's section 5. The rear portion of the rod portion 22a is inclined downward toward the rear and is positioned further to the right of the fuselage as it approaches the front in a plan view, thereby preventing interference between the rod portion 22a and the canopy 41.

[0060] The horizontally extending front portion of the rod portion 22a and the square plate member 22b do not overlap with the canopy 41 in a plan view of the aircraft. In addition, the upper portion of the vertical frame portion 23, the mounting member 25, and the fulcrum member 26 do not overlap with the canopy 41 in a plan view of the aircraft.

[0061] The vertical frame 23 includes a vertically extending rod portion 23a, a rectangular plate member 23b at the upper end, and a rectangular member 23c at the lower end. The rectangular member 23c is welded to the lower end of the rod portion 23a. The rectangular plate member 23b is welded to the upper end of the rod portion 23a. The left side portion of the rectangular member 23c, extending longitudinally on the left side of the vehicle body, is bolted to the left side portion of the front of the side panel 13. In other words, the vertical frame 23 is supported on the left side of the driver's unit 5 (the end of the driver's unit 5 toward the center of the vehicle body). The rod portion 23a is erected in an inclined position (forward leaning position) so that its upper end is positioned closer to the front of the vehicle body. The rectangular plate member 22b of the front-rear frame 22 and the rectangular plate member 23b of the vertical frame 23 are bolted together. At this time, the lower surface of the rectangular plate member 22b abuts against the upper surface of the rectangular plate member 23b.

[0062] The left side surface of the rectangular member 23c on the left side of the fuselage extends vertically and also front-to-rear. A triangular portion is formed on this left side surface. The rear edge of this triangular portion is welded to the rod portion 23a from top to bottom. That is, the vertical frame portion 23 is inclined so that the upper portion is positioned closer to the front of the fuselage, and the rectangular member 23c is formed so that its front-to-rear width increases toward the lower portion in a side view of the fuselage. The distance between the front end of the rectangular member 23c and the rear end of the rectangular member 23c increases toward the lower portion. This increases the rigidity of the rod portion 23a.

[0063] In a plan view, the rectangular member 23c is bent into an L-shape. The front end portion of the rectangular member 23c, which is bent into an L-shape in a plan view, extends from the bent portion to the right side of the aircraft body. The front end portion of the rectangular member 23c has a front surface portion facing forward. This front end portion extends up and down along the vertical direction and also extends left and right.

[0064] In addition, a horizontally extending flat surface portion is formed on the upper portion of the rectangular member 23c. This flat surface portion is rectangular in plan view and connects to the upper ends of the front end portion and left side portion of the rectangular member 23c, which are bent and formed into an L-shape in plan view. This horizontally extending flat surface portion extends both forward and backward and left and right. Because the rectangular member 23c is bent and formed into an L-shape in plan view, and the side portion on the left side of the aircraft body of the rectangular member 23c is formed into a triangular shape in side view of the aircraft, a flat surface portion is provided on the upper portion of the rectangular member 23c that connects the front end portion and the left side portion. This gives the rectangular member 23c an overall box-like shape, increasing the overall rigidity of the rectangular member 23c. As a result, the rigidity of the rod portion 23a is increased.

[0065] In this way, the rectangular member 23c that reinforces the vertical frame portion 23 is provided at the lower end of the vertical frame portion 23. Note that the rectangular member 23c may be provided at a portion above the lower end of the vertical frame portion 23, i.e., at the lower part of the vertical frame portion 23.

[0066] The rod portions 23a of the vertical frame portions 23 and the rear portions of the rod portions 22a of the front-rear frame portions 22 are arranged side by side in the fore-and-aft direction of the aircraft, so that the front portions of the rod portions 22a of the front-rear frame portions 22 extend along the fore-and-aft direction of the aircraft.

[0067] The horizontal frame portion 24 includes a rod portion 24a, a handrail frame portion 24b for the driver getting on and off through the boarding / alighting opening 5A, a square plate member 24c at the right end of the vehicle body, and a flat plate member 24d at the left end of the vehicle body. The rod portion 24a extends laterally in a plan view of the vehicle body. The rod portion 24a is L-shaped in front and rear views of the vehicle body. The rod portion 24a extends across both the left and right ends of the front panel 12 and extends downward from the right end. The left end of the rod portion 24a is welded to the flat plate member 24d.

[0068] The flat plate members 24d of the horizontal frame portions 24 are connected with bolts to the front portions of the rectangular members 23c of the vertical frame portions 23. In other words, the vertical frame portions 23 and the horizontal frame portions 24 are connected to each other at their flat surface portions. This allows the vertical frame portions 23 and the horizontal frame portions 24 to be firmly connected with a simple configuration. That is, the rectangular members 23c and the flat plate members 24d each have a flat surface portion, and the rectangular members 23c and the flat plate members 24d are connected to each other with their respective flat surface portions flush with each other.

[0069] The square plate member 24c is formed by bending a flat plate member. The upper end of the square plate member 24c is bent into an L-shape when viewed from the front and rear of the aircraft. The square plate member 24c is connected to the rod portion 24a and the handrail frame portion 24b at the right end of the horizontal frame portion 24. An upper surface portion is formed at the upper end of the square plate member 24c. The right end of the rod portion 24a is welded to the upper surface portion of the square plate member 24c. The handrail frame portion 24b is also welded to the square plate member 24c. As a result, the handrail frame portion 24b is provided at the right end of the horizontal frame portion 24.

[0070] The handrail frame portion 24b is connected to the outer lateral end of the front panel 12. That is, the right end of the lateral frame portion 24 is supported by the outer lateral end of the front panel 12 in the driver's section 5 and is adjacent to the boarding / alighting door 5A of the driver's section 5.

[0071] In this way, the horizontal frame portions 24 are connected to the lower portions of the vertical frame portions 23 of the front and rear frame portions 22 and to the outer lateral end portions of the front panel 12 of the aircraft, and extend along the left-right direction of the aircraft. As a result, the front and rear frame portions 22 and the vertical frame portions 23 are firmly supported by the horizontal frame portions 24.

[0072] The horizontal frame portion 24 is located forward of the steering operation lever 16. The horizontal frame portion 24 is also located below the upper end of the steering operation lever 16. Therefore, when the driver sitting in the driver's seat 11 monitors the field in front of the machine body, the driver can easily check the field without being concerned about the horizontal frame portion 24.

[0073] An illumination unit 32 is supported on the rectangular plate member 24c. The illumination unit 32 illuminates the area around the front right part of the vehicle body. The illumination unit 32 can also swing around a vertical axis. Therefore, for example, when an operator (including the driver) rotates the illumination unit 32 backward, the illumination unit 32 can illuminate the area around the right side of the driver's seat 5.

[0074] An automatic driving operation unit 31 is bolted to the horizontal frame portion 24. In other words, the automatic driving operation unit 31 is supported by the horizontal frame portion 24. Although not shown, the combine harvester of this embodiment has a control device for executing automatic driving and automatic steering. The automatic driving operation unit 31 accepts manual operations for outputting commands to the control device. The automatic driving operation unit 31 is provided with a plurality of buttons related to automatic steering and automatic driving. Therefore, for example, a driver can operate the automatic driving operation unit 31 to cause the combine harvester (harvester) to perform automatic steering or automatic driving. Note that the control device may be configured to perform at least one of automatic driving and automatic steering.

[0075] The automatic driving operation unit 31 is disposed laterally outward and forward of the vehicle body relative to the steering control lever 16. In a plan view of the vehicle body, the automatic driving operation unit 31 does not overlap with the canopy 41, which is positioned in the cover position. In a plan view of the vehicle body, the automatic driving operation unit 31 and the irradiation unit 32 overlap.

[0076] [Regarding the swing support structure of the mounting member] The structure of the mounting member 25 will be described with reference to Figures 5 to 8. The fulcrum member 26 supports the mounting member 25 so that it can swing. The fulcrum member 26 has a swing bearing portion 26A. The base end rotation portion 25A of the mounting member 25 is fitted into the swing bearing portion 26A of the fulcrum member 26, and the mounting member 25 swings around the swing axis X1 of the base end rotation portion 25A. As a result, the mounting member 25 swings around the swing axis X1 of the base end rotation portion 25A. In addition, a handle 42 for swinging the mounting member 25 is attached to the mounting member 25.

[0077] As shown in Figure 6, a cylindrical small diameter portion 26P is formed on the right side of the body of the rocking bearing portion 26A, and a cylindrical large diameter portion 26Q is formed on the right side of the body of the rocking bearing portion 26A. The inner diameter of the small diameter portion 26P is approximately the same as or slightly larger than the outer diameter of the base end rotation portion 25A of the mounting member 25. This allows the base end rotation portion 25A of the mounting member 25 to be inserted through the small diameter portion 26P. In addition, a step portion 26R is formed between the small diameter portion 26P and the large diameter portion 26Q.

[0078] The base end pivot portion 25A of the mounting member 25 is inserted into the large diameter portion 26Q, and a coil spring 27 and a bushing portion 28 are fitted onto the base end pivot portion 25A. One end of the coil spring 27 abuts against the stepped portion 26R, and the other end of the coil spring 27 abuts against the bushing portion 28. The outer diameter of the bushing portion 28 is approximately the same as the inner diameter of the large diameter portion 26Q. Therefore, the bushing portion 28 can hold the mounting member 25 so that the base end pivot portion 25A of the mounting member 25 extends along the oscillation axis X1.

[0079] A screw groove 25S is formed in the rear end of the base end pivot portion 25A of the mounting member 25, and a nut Nu is screwed into this screw groove 25S. A washer 29 is interposed between the bushing portion 28 and the nut Nu. In this state, the nut Nu is fastened to the base end pivot portion 25A of the mounting member 25.

[0080] A hole is drilled in the base end pivot portion 25A of the mounting member 25 along a direction perpendicular to the pivot axis X1, and a lock pin 30 is inserted through this hole. The lock pin 30 abuts against the right side of the swing bearing portion 26A, restricting the mounting member 25 from sliding leftward. When the lock pin 30 abuts against the right side of the swing bearing portion 26A, the coil spring 27 is compressed. This biases the lock pin 30 to abut against the right side of the swing bearing portion 26A. As will be described in detail later, a vertical groove 26V and a horizontal groove 26H are formed in the right side of the swing bearing portion 26A (see FIG. 8 ), and the lock pin 30 can engage with each of the vertical groove 26V and the horizontal groove 26H. The vertical groove 26V and the horizontal groove 26H are formed to intersect perpendicularly or approximately perpendicularly with each other. The lock pin 30, the vertical groove 26V, and the horizontal groove 26H correspond to the "positioning mechanism" described in the claims.

[0081] The mounting member 25 has a base end pivot portion 25A, an arm portion 25B, a mounting plate portion 25C, a web portion 25D, a base end bracket portion 25E, and an abutment portion 25F. One end of the arm portion 25B is welded to the end of the base end pivot portion 25A on the side where the driver's seat 11 is located. The mounting plate portion 25C is welded to the other end of the arm portion 25B. The receiver 20 is bolted to the flat surface portion of the mounting plate portion 25C. When the mounting member 25 is in the stored state, the flat surface portion of the mounting plate portion 25C faces forward or downward and forward. When the mounting member 25 is in the used state, the flat surface portion of the mounting plate portion 25C faces upward.

[0082] The arm portion 25B is formed in a flat plate shape. The arm portion 25B has flat surface portions along the front-rear and up-down directions. A flat web portion 25D is welded to the longitudinal center portion of the arm portion 25B. The web portion 25D extends along the longitudinal direction of the arm portion 25B. The web portion 25D has flat surface portions along the longitudinal direction of the arm portion 25B and the left-right direction of the vehicle. Therefore, the mounting member 25 is formed in a T-shape when viewed in a longitudinal cross section of the arm portion 25B and the web portion 25D. Furthermore, the web portion 25D is formed in a trapezoidal shape so that it becomes thinner in the left-right direction of the vehicle as it moves away from the swing axis X1. This increases the rigidity of the arm portion 25B and reduces the moment load when the mounting member 25 swings around the swing axis X1.

[0083] The base end bracket portion 25E is welded to the lower portion of the web portion 25D and to the base end pivot portion 25A. The base end bracket portion 25E is formed by bending a flat plate member into an L-shape. The base end bracket portion 25E extends from one end on the side where the receiving device 20 is located to the other end opposite the side where the receiving device 20 is located, sandwiching the base end pivot portion 25A. One end of the base end bracket portion 25E is bent into an L-shape and welded to the lower portion of the web portion 25D. A weld nut is provided at one end of the base end bracket portion 25E, and an abutment portion 25F is attached to this weld nut. A retaining member 53 is connected to the other end region of the base end bracket portion 25E, as will be described in detail below.

[0084] The handle 42 has a grip portion that is grasped by an operator or the like. Bolt insertion portions are provided at both longitudinal ends of the handle 42, sandwiching the grip portion. Weld nuts are provided on the base end and free end of the arm portion 25B, sandwiching a welded portion to the web portion 25D. Bolts are inserted into the bolt insertion portions at both ends of the handle 42, and both ends of the handle 42 are bolted to the weld nuts of the arm portion 25B. The web portion 25D is located between both ends of the handle 42. The handle 42 is attached to the side of the mounting member 25 that is closer to the driver's seat 11 in the left-right direction of the machine body. The handle 42 is also attached to a location on the mounting member 25 near the swing axis X1.

[0085] The handlebars 42 swing integrally with the receiving device 20 around the swing axis X1 of the receiving device 20. For example, when the driver swings the handlebars 42 clockwise in FIG. 5, the mounting member 25 enters the use state, and the receiving device 20 swings upward together with the mounting member 25. The receiving device 20 is then positioned directly above the swing axis X1. At this time, the handlebars 42 are positioned directly or substantially directly above the swing axis X1 when viewed in the axial direction of the swing axis X1. In addition, the lock pin 30 fits into the lateral groove 26H on the right side of the vehicle body of the swing bearing 26A. Therefore, the angle of the mounting member 25 when in use is firmly maintained by the lateral groove 26H.

[0086] For example, when the operator swings the handle 42 counterclockwise in Figure 5, the mounting member 25 swings downward and forward from the in-use position. At this time, the lock pin 30 comes out of the horizontal groove 26H against the biasing force of the coil spring 27. The mounting member 25 then enters the stored state. The receiving device 20 also swings downward together with the mounting member 25.

[0087] In this embodiment, the mounting member 25 has an abutment portion 25F that can abut against the rectangular plate member 23b. The head of the abutment portion 25F is made of an elastic material. A weld nut is fixed to the portion of the base-end bracket portion 25E that connects to the web portion 25D. The abutment portion 25F is connected to this weld nut with a bolt. The elastic material at the head of the abutment portion 25F is, for example, rubber, but may also be rock wool, urethane, or the like.

[0088] As shown by the two-dot chain line in Figure 5, when the receiving device 20 and the mounting member 25 swing downward, the head of the abutment portion 25F abuts against the front surface of the rectangular plate member 23b. The state in which the abutment portion 25F and the rectangular plate member 23b abut against each other is the storage state of the mounting member 25. In other words, the support member 21 has the rectangular plate member 23b that abuts against the mounting member 25, preventing the mounting member 25 from swinging around the swing axis X1 beyond the storage state position. The front surface of the rectangular plate member 23b corresponds to the "first blocking portion" recited in the claims.

[0089] The abutment portion 25F has a bolt portion. By adjusting the position of this bolt portion, it is possible to adjust the distance between the weld nut on the base-end bracket portion 25E and the head of the abutment portion 25F. In other words, the abutment portion 25F is configured to be position-adjustable. This allows for adjustment of the positions (height adjustment) of the receiving device 20 and the mounting member 25 when the mounting member 25 is in the stored state.

[0090] When the abutment portion 25F is positioned so that the mounting member 25 is tilted forward and downward by 90 degrees relative to the mounting member 25 in the use state shown by the solid line in FIG. 5 , the lock pin 30 fits into the vertical groove 26V on the right side of the vehicle body of the rocking bearing portion 26A. Therefore, the angle of the mounting member 25 in the storage state is firmly maintained by the vertical groove 26V. Note that in this embodiment, as shown in FIG. 8 , the vertical groove 26V and the lateral groove 26H are formed to intersect each other perpendicularly or approximately perpendicularly, but this is not limiting. For example, the vertical groove 26V may be configured to intersect the lateral groove 26H obliquely rather than perpendicularly so that the lock pin 30 fits into the vertical groove 26V at the angle of the mounting member 25 in the storage state shown by the two-dot chain line in FIG. 5 .

[0091] In this embodiment, the fulcrum member 26 is provided with a corner 26B, which is covered with an elastic material. The head of the abutting portion 25F is configured to abut against the front end of the corner 26B when the mounting member 25 is in the use state. In other words, the support member 21 has a corner 26B that, when the mounting member 25 abuts against it, prevents the mounting member 25 from swinging around the oscillation axis X1 beyond the use state position. The abutting portion 25F is configured to abut against the corner 26B. Furthermore, when the abutting portion 25F abuts against the corner 26B, the mounting member 25 is prevented from swinging around the oscillation axis X1 beyond the use state position. Furthermore, the head of the abutting portion 25F and the corner 26B are each made of an elastic material. This reduces the impact when the head of the contact portion 25F and the corner portion 26B come into contact with each other, reducing the risk of damage to the head of the contact portion 25F and the corner portion 26B. The corner portion 26B corresponds to the "second prevention portion" described in the claims. The elastic body covering the corner portion 26B is, for example, rubber, but may also be rock wool, urethane, or the like.

[0092] 5 to 9, this embodiment is provided with a locking mechanism 50 and a holding member 53. The locking mechanism 50 is for holding the receiving device 20 in a position for use. The locking mechanism 50 is configured to be changeable between a fixed state in which the mounting member 25 is fixed in a use state and a released state in which the mounting member 25 is released from the use state. The holding member 53 holds the locking mechanism 50 in the released state.

[0093] The locking mechanism 50 includes a locking portion 51 and a locked portion 52. The locking portion 51 includes an L-shaped portion 51A, a hook portion 51B, a coil spring 51C, a washer 51D, and a snap pin 51E. The locked portion 52 is formed with one locked hole 52a and two bolt insertion holes 52b.

[0094] The holding member 53 is connected to the base-end bracket portion 25E. The holding member 53 has a round bar portion 53A and a flat plate portion 53B. The round bar portion 53A of the holding member 53 protrudes from the base-end bracket portion 25E toward the side where the driving unit 5 is located. The flat plate portion 53B of the holding member 53 is welded to the longitudinal center portion of the round bar portion 53A. A round hole 53h is drilled in the flat plate portion 53B of the holding member 53, and the engaging portion 51 of the locking mechanism 50 is inserted into the round hole 53h.

[0095] The right end of the L-shaped portion 51A on the side where the mounting member 25 is located extends along the left-right direction of the aircraft body. The left end of the L-shaped portion 51A on the opposite side to the side where the mounting member 25 is located is bent into an L shape.

[0096] An insertion hole is formed in the base-end bracket portion 25E, and this insertion hole overlaps with the round hole 53h of the flat portion 53B in a side view of the aircraft body. The right end of the L-shaped portion 51A is inserted through the round hole 53h and the insertion hole of the base-end bracket portion 25E.

[0097] The coil spring 51C and washer 51D are fitted onto the right end of the L-shaped portion 51A and are positioned between the flat portion 53B and the base-end bracket portion 25E. An insertion hole for a snap pin 51E is formed in the right end of the L-shaped portion 51A. With the coil spring 51C and washer 51D fitted onto the right end of the L-shaped portion 51A, the snap pin 51E is inserted into the insertion hole. The washer 51D is always positioned to the right of the aircraft body (the side away from the locked portion 52) relative to the snap pin 51E. The coil spring 51C is sandwiched and compressed between the washer 51D and the flat portion 53B. The coil spring 51C presses against both the washer 51D and the flat portion 53B. Therefore, a biasing force is applied by the coil spring 51C to the L-shaped portion 51A, displacing it toward the right side of the aircraft body.

[0098] The hook portion 51B is welded and fixed between the right end and the left end of the L-shaped portion 51A. The hook portion 51B is configured to be able to come into contact with the round bar portion 53A of the holding member 53 by rotating the L-shaped portion 51A about the axis of the lateral direction of the aircraft body.

[0099] The locked portion 52 is fixed to the rectangular plate member 23b with bolts. Bolts are inserted into two bolt insertion holes 52b formed in the locked portion 52 and fastened to weld nuts on the rectangular plate member 23b. The inner diameter of the bolt insertion holes 52b is larger than the outer diameter of the bolts. This allows the position of the locked portion 52 relative to the rectangular plate member 23b to be adjusted. An operator can attach the locked portion 52 to the rectangular plate member 23b so that the right end of the L-shaped portion 51A passes through the locked hole 52a.

[0100] When the right end of the L-shaped portion 51A is inserted through the locking hole 52a while the mounting member 25 is in the use state, the locking mechanism 50 enters a fixed state that fixes the mounting member 25 in the use state. At this time, the state in which the right end of the L-shaped portion 51A is inserted through the locking hole 52a is maintained by the biasing force of the coil spring 51C.

[0101] To change the locking mechanism 50 from this state to the unlocked state, the operator pulls the L-shaped portion 51A toward the driver's control unit 5 against the biasing force of the coil spring 51C, causing the right end of the L-shaped portion 51A to come out of the locking hole 52a. The operator then rotates the L-shaped portion 51A around the axis of the vehicle body lateral to bring the hook portion 51B into contact with the round bar portion 53A of the holding member 53. The extending end of the round bar portion 53A is tapered, with a diameter decreasing toward the tip. An engagement hole is formed in the hook portion 51B, and the engagement hole in the hook portion 51B engages with the tapered extending end of the round bar portion 53A. At this time, the right end of the L-shaped portion 51A comes out of the locking hole 52a, and the locking portion 51 is maintained hooked on the holding member 53 by the biasing force of the coil spring 51C. This puts the locking mechanism 50 into the released state. At this time, the holding member 53 holds the locking mechanism 50 in the released state.

[0102] To change the locking mechanism 50 from this state to the fixed state, the operator pulls the L-shaped portion 51A toward the driving unit 5 against the biasing force of the coil spring 51C and rotates the L-shaped portion 51A until the angle at which the hook portion 51B does not get caught on the extended end of the round bar portion 53A. When the operator then releases the L-shaped portion 51A, the biasing force of the coil spring 51C causes the right end of the L-shaped portion 51A to pass through the locking hole 52a, and the locking mechanism 50 enters the fixed state.

[0103] When the mounting member 25 is in the in-use state and the locking mechanism 50 is in the released state, the locking pin 30 fits into the horizontal groove 26H at the right end of the rocking bearing 26A. As a result, the angle of the arm 25B when the mounting member 25 is in the in-use state is firmly maintained by the locking pin 30 and the horizontal groove 26H (see FIG. 8 ). This prevents the receiving device 20 and mounting member 25 from falling under their own weight without the operator operating the handle 42, even if the locking mechanism 50 is changed to the released state. In this way, the positioning mechanism (locking pin 30 and the horizontal groove 26H) is configured separately from the locking mechanism 50 and positions the mounting member 25 when in use.

[0104] 6, the base end rotation portion 25A of the mounting member 25 is fitted into the swing bearing portion 26A of the fulcrum member 26, and the base end rotation portion 25A and the swing bearing portion 26A are located on the opposite side of the arm portion 25B from the driver's seat 11. Therefore, the locking mechanism 50 and the positioning mechanism (lock pin 30 and lateral groove portion 26H) are arranged on one side and the other side of the mounting member 25 in the direction of the swing axis X1.

[0105] Other Embodiments The present invention is not limited to the configurations exemplified in the above-described embodiments, and other representative embodiments of the present invention will be exemplified below.

[0106] (1) The mounting member 25 is configured to be able to change between the use state and the storage state by swinging up and down around the swing axis X1. This embodiment is not limited to this, and the mounting member 25 may be configured to be able to change between the use state and the storage state by sliding up and down.

[0107] (2) The pivot axis X1 of the mounting member 25 extends in the left-right direction of the aircraft body. This embodiment is not limited to this, and the pivot axis X1 of the mounting member 25 may extend in the fore-aft direction of the aircraft body. In other words, the mounting member 25 may be configured to pivot about the pivot axis X1 extending in the horizontal direction. Note that the "horizontal direction" described in the claims is not limited to the strict meaning of the horizontal direction, but also includes the meaning of an approximately horizontal direction.

[0108] (3) In the above embodiment, the engaging portion 52 is connected to the arm portion 25B, but the engaging portion 52 may not be provided. In this case, the front end of the L-shaped portion 51A of the engaging portion 51 may be configured to contact the lower edge of the arm portion 25B on the rotation path of the arm portion 25B. In this state, the mounting member 25 is fixed in the usage state by being supported from below by the engaging portion 51.

[0109] (4) In the above embodiment, a positioning mechanism (lock pin 30 and horizontal groove 26H) that positions mounting member 25 in the usage state is provided, but the positioning mechanism may be configured to include only horizontal groove 26H that positions mounting member 25 in the usage state, without including vertical groove 26V. Alternatively, a configuration without a positioning mechanism may be used. If a positioning mechanism is not provided, for example, sliding friction during rotation may be applied to base end rotation portion 25A that is fitted into swing bearing portion 26A, so that mounting member 25 does not rotate under its own weight.

[0110] (5) In the above-described embodiment, the locking mechanism 50 and the positioning mechanism (the locking pin 30 and the lateral groove portion 26H) are disposed on the same side of the mounting member 25 in the direction of the pivot axis X1. However, the present invention is not limited to this embodiment, and the locking mechanism 50 and the positioning mechanism may be configured to be separated by the mounting member 25.

[0111] (6) The configuration may include only one of the first blocking portion (the front surface of the rectangular plate member 23b) and the second blocking portion (the corner portion 26B). Alternatively, the configuration may include neither the first blocking portion nor the second blocking portion, in which case the abutment portion 25F may not be provided.

[0112] (7) Both the first blocking portion (the front surface of the rectangular plate member 23b) and the second blocking portion (the corner portion 26B) may be made of an elastic material. In this case, the abutting portion 25F may be made of a non-elastic material. Also, both the first blocking portion and the second blocking portion may be made of a non-elastic material.

[0113] (8) The handle 42 for swinging the mounting member 25 may not be attached to the mounting member 25. In this case, a linkage mechanism or a wire linkage mechanism may be interposed between the handle 42 and the mounting member 25. Alternatively, the handle 42 may not be provided.

[0114] (9) In the above-described embodiment, the locking mechanism 50 locks the mounting member 25 in the use state. However, this is not limiting, and for example, a second locking mechanism separate from the locking mechanism 50 may be provided, and the second locking mechanism may be configured to lock the mounting member 25 in the storage state. In this case, the mounting member 25 is configured to be able to be locked in the storage state.

[0115] The configurations disclosed in the above-described embodiments (including other embodiments, the same applies hereinafter) can be applied in combination with the configurations disclosed in other embodiments, unless a contradiction occurs. Furthermore, the embodiments disclosed in this specification are merely examples, and the present invention is not limited to these, and can be modified as appropriate within the scope of the purpose of the present invention.

[0116] The present invention is applicable to harvesters. Therefore, in addition to the head-feeding combine harvester exemplified in the above embodiment, the present invention is applicable to various harvesters such as a conventional combine harvester, a corn harvester, a sugarcane harvester, a soybean harvester, and a root vegetable harvester.
