Description

[Technical field]

[0001] The present invention relates to a harvester. [Background technology]

[0002] For example, the harvester (referred to as a "combine" in the document) disclosed in Patent Document 1 is equipped with a receiver (referred to as a "GPS antenna unit" in the document) that receives signals from satellites, and a mounting member (referred to as a "stay" in the document) to which the receiver is attached. The mounting member is configured to be changeable between a usage state (referred to as a "use position" in the document) in which the receiver is used, and a storage state (referred to as a "storage position" in the document) that is lower than the usage state.

[0003] [Patent Document 1] JP 2020-103055 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when the receiving device receives a signal from a satellite, the mounting member is held in the use state to improve positioning accuracy, but since vibrations tend to increase when the harvester is traveling, it is important that the mounting member is firmly held in the use state. However, if the mounting member is held too firmly in the use state, for example, when a worker or the like changes the state of the mounting member from the use state to the storage state, the worker or the like may find it troublesome to release the holding. For this reason, it is also important that the mounting member is easily changed in state by the worker or the like.

[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. [Means for solving the problem]

[0006] The harvester of the present invention comprises a driving section having a driver's seat, a receiving device for receiving signals from a satellite, a mounting member to which the receiving device is attached, and a support member extending upward from the driving section and supporting 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 changeable between a fixed state in which the mounting member is fixed to the usage state and a released state in which the mounting member is released from its fixation 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 that fixes the mounting member in a use state is provided. Therefore, compared to a configuration in which a locking mechanism is not provided, the mounting member is held firmly in the use state. In addition, 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 held by the 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, if the locking mechanism is held in the unlocked state by the holding member, the mounting member can be changed to the storage state as it is. This allows the operator or the like to easily change the state of the mounting member. As a result, a harvester that can smoothly change the state of the mounting member to which the receiving device is attached is realized.

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

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

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

[0011] With this configuration, the mounting member is positioned in a position for the stored state by the positioning mechanism, which makes it possible to temporarily fasten the mounting member in the stored state.

[0012] In the present invention, the mounting member is configured to swing around a swing axis extending horizontally so as to be changeable between the use state and the stored 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 direction of the swing axis.

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

[0014] In the present invention, the mounting member is configured to be able to swing around a swing axis extending horizontally and change its state between the use state and the stored 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 stored state when the mounting member abuts against the first prevention portion.

[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 is capable of abutting against the first blocking portion, and the abutment portion is formed of an elastic body.

[0017] With this configuration, the mounting member in the stored state is less likely to be subjected to impacts, 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 blocking 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 blocking portion.

[0021] With this configuration, the mounting member is in a use state when the mounting member and the second blocking portion come into contact with each other. Therefore, when the mounting member and the second blocking portion come into contact with each other, the mounting member is maintained in a use state, and it is easy to change the state of 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] With this configuration, the mounting member is less likely to be subjected to impacts when in use, and the mounting member is prevented 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 preventing portion, and that the abutment portion abuts against the second preventing portion to prevent the mounting member from swinging around the swing axis beyond the position of the usage state.

[0025] With this configuration, the mounting member is in a usable state when the abutting portion and the second blocking portion abut against each other. Therefore, when the abutting portion and the second blocking portion are in abutting state, the mounting member is maintained in a usable state, and it is easy to change the locking mechanism from the released state to the fixed state. In addition, the abutting portion is interposed between the mounting member and the second blocking portion, which prevents the mounting member from being scratched.

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

[0027] With this configuration, the operability of the mounting member is improved compared to a configuration in which no handle is provided.

[0028] In the present invention, it is preferable that the handle is attached to the mounting 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 position closer to the free end of the mounting member, an operator or the like can 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 aircraft, 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 aircraft.

[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 capable of being 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. [Brief description of the drawings]

[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 the combine harvester, and FIG. 2 is a plan view of the combine harvester. Here, for ease of understanding, in this embodiment, unless otherwise specified, "front" (the direction of the arrow "F" shown in FIG. 1) means the front in the longitudinal direction (traveling direction) of the machine body, and "rear" (the direction of the arrow "B" shown in FIG. 1) means the rear in the longitudinal direction (traveling direction) of the machine body. In addition, "up" (the direction of the arrow "U" shown in FIG. 1) and "down" (the direction of the arrow "D" shown in FIG. 1) are positional relationships in the vertical direction (direction perpendicular to the horizontal plane) and indicate relationships at ground height. Furthermore, the left-right direction or lateral direction means the transverse direction of the machine body (machine body width direction) perpendicular to the longitudinal direction of the machine body. That is, "left" (the direction of the arrow "L" shown in FIG. 2) and "right" (the direction of the arrow "R" shown in FIG. 2) mean the leftward and rightward directions of the machine body, respectively. The same applies to the drawings from FIG. 3 onwards.

[0037] [Overall information about combine harvesters] As shown in FIG. 1, the traveling body 1 of the combine harvester includes a body frame 2, which is formed by connecting a plurality of steel materials such as square pipe materials. 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 portion of the front part of the traveling body 1. A driver rides in the driving unit 5. Since the combine harvester (harvest machine) 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 disposed below the driving unit 5. The driving unit 5 is not covered by a cabin and is open to the outside.

[0038] The reaping unit 4 is provided in a manner that allows it to be raised and lowered at the front of the traveling body 1. The reaping unit 4 has a plurality of dividers 4a and a plurality of raising devices 4b. The reaping unit 4 raises and cuts the planted stalks (crops) of rice or wheat in a plurality of planting rows in front of the traveling body 1 with the raising device 4b, and transports the cut reaped stalks toward the rear of the machine body. At the rear of the machine body frame 2, a threshing device 6 and a grain tank 8 are supported side by side. The threshing device 6 is disposed behind the reaping unit 4, and the grain tank 8 is disposed 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 cut stalks cut by the reaping unit 4 toward the rear. The threshing device 6 threshes the input reaped stalks, and a sorting process is performed to separate the grains and dust obtained by the threshing process. The grain tank 8 stores the grains that have been threshed and transported from the threshing device 6. A transport device 9 that removes 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 outlet 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 outlet 9C and discharges them outside the machine from the discharge outlet 9C.

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

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

[0042] The combine harvester of this embodiment is equipped with a receiver 20 for satellite positioning. 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 obtain the vehicle's position. The receiver 20 is provided at a position offset to the left side of the machine body (one side in the left-right direction) with respect to the left-right center of the driver's unit 5.

[0043] [Operation section] The driver's section 5 is provided in a state in which it is biased toward the right side of the aircraft body with respect to the center of the aircraft body. As shown in Figs. 1 to 4, the driver's section 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 area of ​​the driver's section 5. A driver sits in the driver's seat 11. A floor section 15 (Fig. 3) is provided between the front panel 12 and the driver's seat 11 in the front-rear 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 section 5 opposite to 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 who sits 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. For example, the traveling speed, engine RPM, remaining fuel level, etc. are displayed on the meter panel (not shown).

[0045] The side panel 13 is provided with a main speed change operation lever 18 and the like. The main speed change operation lever 18 is disposed at the front of the side panel 13. The main speed change operation 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 the speed of a main transmission (not shown) by operating the main speed change operation lever 18.

[0046] A box-shaped rear box 40 is provided behind the driver's seat 11. The rear box 40 protrudes upward from the support 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, an air cleaner for intake to the engine E, an electronic control unit (so-called ECU), etc. are housed inside the rear box 40.

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

[0048] [Support structure for receiving device] In this embodiment, the receiving device 20 is supported by a mounting member 25, and the receiving device 20 and the mounting member 25 are supported so as to be swingable on a support member 21. As shown in Fig. 2, the receiving device 20 and the mounting member 25 are disposed on the left side of the aircraft body with respect to the driver's seat 11. As shown in Figs. 3 and 4, the support member 21 supporting the receiving device 20 and the mounting member 25 is provided with front and rear frame portions 22, a vertical frame portion 23, and a horizontal frame portion 24.

[0049] The front and rear frame sections 22 extend in the front-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 member 25 and the fulcrum member 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 plan views 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. In addition, the support member 21 is 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 body.

[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 the state of the mounting member 25 at this time corresponds to the "use state" described in the claims. The state in which the mounting member 25 is swung downward is shown by a broken line in Fig. 1. The state of the mounting member 25 at this time corresponds to the "storage state" described in the claims. In other words, the mounting member 25 is configured to be able to swing around the swing axis X1 extending horizontally and change its state between a use state in which the receiving device 20 is used and a storage state in which the receiving device 20 is stored at a position lower than the position in the use 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 the position of the receiving device 20 when it is in the stored state, and the positioning accuracy of the receiving device 20 during harvesting work is improved. In addition, 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 in which the combine is stored 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, the receiving device 20 overlaps with the mowing unit 4 in a plan view, and is located at the center of the left and right width of the mowing unit 4. As shown in Figs. 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 Figs. 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 aircraft body relative to the driving section 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 lateral conveying section 9B in the stored state in a plan view of the aircraft 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 lower than the upper end of the horizontal conveying section 9B of the conveying device 9 in the stored state, and is located 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 parts 22). By adjusting the position of the abutment part 25F (see FIG. 5, etc.) with a bolt, the position (height) of the receiving device 20 during storage can be adjusted.

[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 in which it is biased toward the right side of the machine body relative to the center of the machine 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 machine body. The front portion of the front-rear frame section 22 extends horizontally and along the front-rear direction. In a side view of the machine body, the front portion of the front-rear frame section 22 overlaps with the lateral conveying section 9B in the stored state (see FIG. 1).

[0059] The front-rear frame portion 22 has a rod portion 22a extending forward and backward, a square plate member 22b at the front end, and a square plate member 22c at the rear end. The square plate member 22b is welded to the front end of the rod portion 22a. The square plate member 22c is welded to the rear end of the rod portion 22a. The front-rear middle portion of the rod portion 22a is bent. The bottom surface portion of the square plate member 22c is bolted to the upper surface portion of the rear box 40. In other words, the front-rear frame portion 22 is supported on the upper surface portion of the rear box 40. As a result, the rear portion of the rod portion 22a is inclined backward. In other words, the rod portion 22a extends horizontally or approximately horizontally from the vertical frame portion 23 and is inclined backward at the rear. In other words, the rear portion of the rod portion 22a is erected in a forward inclined position on the left side at the rear of the driver's unit 5. In addition, the rear portion of the rod portion 22a is inclined downward toward the rear and is inclined so that the front side is positioned toward the right side of the fuselage in a plan view. This prevents 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. Additionally, 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 portion 23 has a rod portion 23a extending vertically, a square plate member 23b at the upper end, and a square member 23c at the lower end. The square member 23c is welded to the lower end of the rod portion 23a. The square plate member 23b is welded to the upper end of the rod portion 23a. Of the square member 23c, a left side portion extending forward and backward on the left side of the machine body is bolted to the left side portion at the front of the side panel 13. In other words, the vertical frame portion 23 is supported on the left side of the driver's unit 5 (the end portion of the driver's unit 5 on the left and right center side of the machine body). The rod portion 23a is erected in an inclined posture (forward leaning posture) so that the upper side is located toward the front of the machine body. The square plate member 22b of the front-rear frame portion 22 and the square plate member 23b of the vertical frame portion 23 are bolted to each other. At this time, the lower surface portion of the square plate member 22b and the upper surface portion of the square plate member 23b come into contact with each other.

[0062] The left side surface portion 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 portion. The rear edge portion 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 side is located toward the front of the fuselage, and the rectangular member 23c is formed so that the front-to-rear width is wider toward the lower side in the 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 becomes longer toward the lower side. This increases the rigidity of the rod portion 23a.

[0063] In plan view, the rectangular member 23c is bent into an L-shape. The front end portion of the rectangular member 23c that is bent into an L-shape in 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 portion that faces forward. This front end portion extends up and down along the vertical direction and also extends left and right.

[0064] In addition, a flat surface portion along the horizontal direction is formed on the upper part of the rectangular member 23c. This flat surface portion is formed in a quadrangle shape in a plan view, and is connected to the upper end portions of the front end portion and the left side portion of the rectangular member 23c that are bent and formed into an L-shape in a plan view. This flat surface portion along the horizontal direction extends forward and backward, and also extends left and right. The rectangular member 23c is bent and formed into an L-shape in a plan view, the side portion on the left side of the aircraft body of the rectangular member 23c is formed into a triangular shape in a side view of the aircraft body, and a flat surface portion that connects the front end portion and the left side portion is provided on the upper part of the rectangular member 23c. As a result, the entire rectangular member 23c is formed into a box shape, and the overall rigidity of the rectangular member 23c is increased. As a result, the rigidity of the rod portion 23a is increased.

[0065] In this way, the lower end of the vertical frame portion 23 is provided with the rectangular member 23c that reinforces the vertical frame portion 23. Note that the rectangular member 23c may be provided in a portion above the lower end of the vertical frame portion 23, i.e., in the lower portion 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 body, so that the front portions of the rod portions 22a of the front-and-aft frame portions 22 extend along the fore-and-aft direction of the aircraft body.

[0067] The horizontal frame portion 24 is provided with a rod portion 24a, a handrail frame portion 24b for the driver getting on and off through the boarding / alighting entrance 5A, a square plate member 24c at the right end of the body, and a flat plate member 24d at the left end of the body. The rod portion 24a extends in the lateral direction of the body in a plan view of the body. The rod portion 24a is formed in an L-shape in a front view and a rear view of the 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 member 24d of the horizontal frame portion 24 is connected to the front portion of the square member 23c of the vertical frame portion 23 with bolts. That is, the vertical frame portion 23 and the horizontal frame portion 24 are connected to each other at their flat surface portions. This allows the vertical frame portion 23 and the horizontal frame portion 24 to be firmly connected to each other with a simple configuration. That is, the square member 23c and the flat plate member 24d each have a flat surface portion, and the square member 23c and the flat plate member 24d are connected to each other with their respective flat surface portions aligned.

[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. In addition, the handrail frame portion 24b is 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 side end of the front panel 12. That is, the right end of the horizontal frame portion 24 is supported by the outer side 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 portion 24 is connected to the lower portion of the vertical frame portion 23 of the front-rear frame portion 22 and to the outer lateral end portion of the front panel 12 of the fuselage, and extends along the left-right direction of the fuselage. As a result, the front-rear frame portion 22 and the vertical frame portion 23 are firmly supported by the horizontal frame portion 24.

[0072] The horizontal frame portion 24 is located forward of the steering lever 16. Also, the horizontal frame portion 24 is located below the upper end of the steering lever 16. Therefore, when the driver seated 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] In addition, the irradiation unit 32 is supported on the square plate member 24c. The irradiation unit 32 irradiates the periphery of the right front part of the machine body. In addition, the irradiation unit 32 can swing about a vertical axis. Therefore, for example, when an operator (including a driver) rotates the irradiation unit 32 backward, the irradiation unit 32 can irradiate the periphery of the right side of the driver's unit 5.

[0074] An automatic travel operation unit 31 is bolted to the horizontal frame portion 24. In other words, the automatic travel 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 performing automatic travel and automatic steering. The automatic travel operation unit 31 accepts manual operations for outputting commands to the control device. The automatic travel operation unit 31 is provided with a plurality of buttons related to automatic steering and automatic travel. Therefore, for example, a driver can operate the automatic travel operation unit 31 to cause the combine harvester (harvest machine) to perform automatic steering or automatic travel. The control device may be configured to perform at least one of automatic travel and automatic steering.

[0075] The automatic driving operation unit 31 is disposed laterally outboard and forward of the vehicle body relative to the steering operation lever 16. The automatic driving operation unit 31 does not overlap with the canopy 41 located in the cover position in a plan view of the vehicle body. The automatic driving operation unit 31 and the irradiation unit 32 overlap with each other in a plan view of the vehicle body.

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

[0077] As shown in Fig. 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 size of 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 rotating portion 25A of the mounting member 25. Therefore, the base end rotating portion 25A of the mounting member 25 can 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 rotating portion 25A of the mounting member 25 is inserted into the large diameter portion 26Q, and the coil spring 27 and the bushing portion 28 are fitted onto the base end rotating portion 25A. One end of the coil spring 27 abuts against the step 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 rotating 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 rotating part 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 part 28 and the nut Nu. In this state, the nut Nu is fastened to the base end rotating part 25A of the mounting member 25.

[0080] A hole is drilled in the base end rotating part 25A of the mounting member 25 along a direction perpendicular to the rocking axis X1, and a lock pin 30 is inserted into the hole. The lock pin 30 abuts against the right side of the rocking bearing part 26A and restricts the sliding movement of the mounting member 25 to the left of the body. When the lock pin 30 abuts against the right side of the rocking bearing part 26A, the coil spring 27 is compressed. Therefore, the lock pin 30 is biased to abut against the right side of the rocking bearing part 26A. Although details will be described later, a vertical groove part 26V and a horizontal groove part 26H are formed on the right side of the body of the rocking bearing part 26A (see FIG. 8), and the lock pin 30 can engage with each of the vertical groove part 26V and the horizontal groove part 26H. The vertical groove part 26V and the horizontal groove part 26H are formed so as to intersect each other perpendicularly or approximately perpendicularly. The lock pin 30, the vertical groove portion 26V and the horizontal groove portion 26H correspond to a "positioning mechanism" recited in the claims.

[0081] The mounting member 25 has a base end rotation 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 rotation 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 fixed by bolts 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 faces forward and downward. 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 direction and the up-down direction. A flat plate-shaped 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 machine body. Therefore, the mounting member 25 is formed in a T-shape in a longitudinal cross-sectional view of the arm portion 25B and the web portion 25D. In addition, the web portion 25D is formed in a trapezoidal shape so that it becomes thinner in the left-right direction of the machine body 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 the base end rotation 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 on the opposite side to the side where the receiving device 20 is located, sandwiching the base end rotation 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 a contact portion 25F is attached to the weld nut. A holding member 53 is connected to the other end side region of the base end bracket portion 25E, which will be described in detail later.

[0084] The handle 42 has a grip portion that is gripped by an operator or the like. Bolt insertion portions are provided at both longitudinal ends of the handle 42, sandwiching the grip portion. Welded nuts are provided at the base end and free end of the arm portion 25B, sandwiching a welded portion with 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 welded 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 on the driver's seat 11 side 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 pivot axis X1.

[0085] The handle 42 swings together with the receiving device 20 around the swing axis X1 of the receiving device 20. For example, when the driver swings the handle 42 clockwise in FIG. 5, the mounting member 25 is brought into 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 handle 42 is positioned directly or substantially directly above the swing axis X1 when viewed in the axial direction of the swing axis X1. The lock pin 30 also 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 in the use state is firmly held by the lateral groove 26H.

[0086] For example, when an operator swings the handle 42 counterclockwise in FIG. 5, the mounting member 25 swings downward and forward from the position of the use state. At this time, the lock pin 30 comes out of the horizontal groove portion 26H against the biasing force of the coil spring 27. Then, the mounting member 25 enters the stored state. In addition, the receiving device 20 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 square plate member 23b. The head of the abutment portion 25F is made of an elastic body. A weld nut is fixed to a portion of the base end bracket portion 25E that is connected to the web portion 25D. The abutment portion 25F is connected to the weld nut with a bolt. The elastic body at the head of the abutment portion 25F is, for example, rubber, but may be rock wool, urethane, or the like.

[0088] As shown by the two-dot chain line in Fig. 5, when the receiving device 20 and the mounting member 25 swing downward, the head of the abutment portion 25F abuts against the front portion of the square plate member 23b. The state in which the abutment portion 25F and the square 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 square plate member 23b that prevents the mounting member 25 from swinging beyond the position in the storage state around the swing axis X1 by abutting against it. The front portion of the square plate member 23b corresponds to the "first blocking portion" described 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 of 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 the positions (height adjustment) of the receiving device 20 and the mounting member 25 to be adjusted when the mounting member 25 is in the stored state.

[0090] When the position of the abutting portion 25F is adjusted so that the mounting member 25 is tilted forward and downward by 90 degrees with respect 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 portion 26V on the right side of the machine body of the rocking bearing portion 26A. Therefore, the angle of the mounting member 25 in the stored state is firmly held by the vertical groove portion 26V. In this embodiment, as shown in FIG. 8, the vertical groove portion 26V and the horizontal groove portion 26H are formed so as to intersect each other perpendicularly or approximately perpendicularly, but are not limited to this embodiment. For example, the vertical groove portion 26V may be configured to intersect the horizontal groove portion 26H obliquely rather than perpendicularly so that the lock pin 30 fits into the vertical groove portion 26V at the angle of the mounting member 25 in the stored state shown by the two-dot chain line in FIG. 5.

[0091] In this embodiment, the fulcrum member 26 is provided with a corner portion 26B, and the corner portion 26B is covered with an elastic body. When the mounting member 25 is in a use state, the head portion of the abutting portion 25F is configured to abut against the front end portion of the corner portion 26B. In other words, the support member 21 has a corner portion 26B that prevents the mounting member 25 from swinging around the swing axis X1 beyond the position in the use state when the mounting member 25 abuts against it. The abutting portion 25F is configured to be able to abut against the corner portion 26B. When the abutting portion 25F abuts against the corner portion 26B, the mounting member 25 is prevented from swinging around the swing axis X1 beyond the position in the use state. In addition, the head portion of the abutting portion 25F and the corner portion 26B are each made of an elastic body. This reduces the impact when the head of the contact portion 25F and the corner portion 26B come into contact with each other, and reduces 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] [Regarding the locking mechanism and holding member] As shown in Fig. 5 to Fig. 9, this embodiment includes 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 to the 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 lock mechanism 50 includes an engaging portion 51 and an engaged portion 52. The engaging 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 engaged portion 52 is formed with one engaged 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] Of the L-shaped portion 51A, the right end portion on the side where the mounting member 25 is located extends along the left-right direction of the aircraft body. Of the L-shaped portion 51A, the left end portion 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 the 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 the snap pin 51E is formed at the right end of the L-shaped portion 51A. The snap pin 51E is inserted into the insertion hole with the coil spring 51C and the washer 51D fitted onto the right end of the L-shaped portion 51A. The washer 51D is always positioned on the right side of the machine body (the side away from the locked portion 52) from 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 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 so as to displace the L-shaped portion 51A toward the right side of the machine body.

[0098] The hook portion 51B is fixed by welding 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 the L-shaped portion 51A rotating about an axis that is oriented horizontally of the machine body.

[0099] The locked portion 52 is fixed to the rectangular plate member 23b with bolts. The bolts are inserted into two bolt insertion holes 52b formed in the locked portion 52, and the bolts are fastened to the welded nuts of the rectangular plate member 23b. The inner diameter of the bolt insertion holes 52b is larger than the outer diameter of the bolts. This makes it possible to adjust the position of the locked portion 52 relative to the rectangular plate member 23b. 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 locked hole 52a while the mounting member 25 is in the use state, the locking mechanism 50 is in 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 locked hole 52a is maintained by the biasing force of the coil spring 51C.

[0101] To change the lock mechanism 50 from this state to the release state, the operator pulls the L-shaped portion 51A against the biasing force of the coil spring 51C toward the driver 5, and the right end of the L-shaped portion 51A comes out of the locking hole 52a. Then, the operator rotates the L-shaped portion 51A around the axis of the machine body, so that the hook portion 51B comes into contact with the round bar portion 53A of the holding member 53. The extending end of the round bar portion 53A is tapered so that the diameter becomes smaller toward the tip side. In addition, an engagement hole is formed in the hook portion 51B, and the engagement hole of 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 held hooked on the holding member 53 by the biasing force of the coil spring 51C. This puts the lock mechanism 50 in the released state. At this time, the holding member 53 holds the lock 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 side where the driving part 5 is located 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 is reached. Then, when the operator releases the L-shaped portion 51A, the right end of the L-shaped portion 51A is inserted through the locked hole 52a by the biasing force of the coil spring 51C, and the locking mechanism 50 is fixed.

[0103] When the mounting member 25 is in the use state and the locking mechanism 50 is in the release 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 use state is firmly held by the locking pin 30 and the horizontal groove 26H (see FIG. 8). This prevents the receiver 20 and the 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 release state. In this way, the positioning mechanism (locking pin 30 and horizontal groove 26H) is configured separately from the locking mechanism 50, and positions the mounting member 25 in the use state.

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

[0105] [Another embodiment] 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 described below.

[0106] (1) The mounting member 25 is configured to be able to change between a use state and a storage state by swinging up and down about 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 a use state and a 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 is not limited to the embodiment, and the pivot axis X1 of the mounting member 25 may extend in the front-rear 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 strictly horizontal direction, but also includes the meaning of an approximately horizontal direction.

[0108] (3) In the above embodiment, the locked portion 52 is connected to the arm portion 25B, but the configuration may not include the locked portion 52. In this case, the front end of the L-shaped portion 51A of the locking 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 locking portion 51.

[0109] (4) In the above embodiment, a positioning mechanism (lock pin 30 and lateral groove 26H) for positioning mounting member 25 in the usage state is provided, but the positioning mechanism may be configured to include only lateral groove 26H for positioning mounting member 25 in the usage state, without including vertical groove 26V. Alternatively, a configuration may be used in which no positioning mechanism is provided. When no positioning mechanism is provided, a configuration may be used in which mounting member 25 does not rotate under its own weight, for example, by applying sliding friction during rotation to base end rotating portion 25A fitted into rocking bearing portion 26A.

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

[0111] (6) Only one of the first blocking portion (front surface of the square plate member 23b) and the second blocking portion (corner portion 26B) may be provided. Also, neither the first blocking portion nor the second blocking portion may be provided, and in this case, the contact portion 25F may not be provided.

[0112] (7) Both the first blocking portion (front portion of the square plate member 23b) and the second blocking portion (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 fixes the mounting member 25 in the usage state. This is not limited to the embodiment, 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 fix the mounting member 25 in the storage state. In this case, the mounting member 25 is configured to be fixed in the storage state.

[0115] The configurations disclosed in the above-mentioned embodiments (including other embodiments, the same applies below) can be applied in combination with configurations disclosed in other embodiments, unless a contradiction occurs. In addition, the embodiments disclosed in this specification are merely examples, and the present invention is not limited to these embodiments, and can be appropriately modified within the scope of the present invention. [Industrial Applicability]
