[0005] Patent Document 1: Japanese Patent Application Publication No. 2020-103055 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, when the receiving device receives signals from the satellite, the mounting components are kept in the working state to improve positioning accuracy. But since harvesters often experience significant vibrations during operation, a structure that securely holds the mounting components in this working state is important. However, if the mounting components are held too securely in the working state, it may be difficult to release them when operators need to change their orientation, for example, from the working state to the stored state. Therefore, a structure that allows operators to easily change the orientation of the mounting components is also important.

[0008] The purpose of this invention is to provide a harvester that enables the mounting components equipped with receiving devices to smoothly change state.

[0009] Technical means for solving problems

[0010] The harvester of the present invention is characterized by comprising: a driving unit having a driver's seat; a receiving device for receiving signals from a satellite; a mounting member on which the receiving device is mounted; and a support member extending upward from the driving unit to support the mounting member; the mounting member being configured to change state between a use state in which the receiving device is used and a storage state in which the receiving device is stored at a lower position than in the use state; the harvester also comprises: a locking mechanism capable of changing state between a fixed state in which the mounting member is fixed in the use state and a released state in which the mounting member is released from the use state; and a retaining member holding the locking mechanism in the released state.

[0011] According to the present invention, a locking mechanism is provided to fix the mounting member in the use state. Therefore, compared with a structure without a locking mechanism, the mounting member is firmly held in the use state. Furthermore, the locking mechanism is configured to allow for state changes between a fixed state and a released state, and the released state of the locking mechanism can be maintained by a retaining member. Therefore, for example, when an operator or other person changes the mounting member from the use state to the storage state, if the locking mechanism is held in the released state by the retaining member, the mounting member can then be directly changed to the storage state. Thus, the operator or other person can easily change the state of the mounting member. As a result, a harvester capable of smoothly changing the state of a mounting member equipped with a receiving device can be realized.

[0012] In this invention, preferably, the harvester has a positioning mechanism, which is separately formed from the locking mechanism, and positions the mounting component in the usage state.

[0013] According to this structure, even if the locking mechanism is not in a fixed state, the mounting component can be positioned in the usage state using a positioning mechanism that is separate from the locking mechanism. This allows for temporary fixing of the mounting component in the usage state.

[0014] In this invention, preferably, the positioning mechanism positions the mounting component in the stored state.

[0015] According to this structure, the mounting components are positioned in the stowed state by the positioning mechanism.

[0016] This allows for the temporary fixing of installation components while they are in a stowed-down state.

[0017] In this invention, preferably, the mounting member is configured to swing about a swing axis extending in a horizontal direction, enabling state changes between the use state and the storage state, and the locking mechanism and the positioning mechanism are separately configured on one side and the other side relative to the mounting member in the direction of the swing axis.

[0018] According to this structure, the locking mechanism and the positioning mechanism are separately configured on one side and the other side relative to the mounting components. This results in a structure in which the entire mechanism achieves balance along the direction of the swing axis.

[0019] In this invention, preferably, the mounting member is configured to swing about a swing axis extending in a horizontal direction, enabling state changes between the use state and the storage state. The support member has a first blocking part, which prevents the mounting member from swinging past the storage state position about the swing axis by abutting against the mounting member.

[0020] According to this structure, the first blocking part can firmly support the mounting component in the stored state.

[0021] In this invention, preferably, the mounting member has an abutting portion capable of abutting against the first blocking portion, the abutting portion being made of an elastomer.

[0022] This structure prevents the mounting components from being damaged by impact when they are stowed.

[0023] In this invention, preferably, the abutting portion is configured to be position-adjustable.

[0024] This structure allows for adjustment of the position of the receiving device when the mounting components are in the stowed state.

[0025] In this invention, preferably, the support member has a second blocking portion, which prevents the mounting member from swinging about the swing axis past the position of the use state by abutting against the mounting member.

[0026] According to this structure, the mounting member is in the working state when it abuts against the second stop. Therefore, if the mounting member and the second stop are in the abutting state, the mounting member remains in the working state, thereby facilitating the change of the locking mechanism from the released state to the fixed state.

[0027] In this invention, preferably, the second blocking part is made of an elastomer.

[0028] This structure prevents the mounting components from being damaged by impacts during use.

[0029] In this invention, preferably, the abutting portion is configured to abut against the second blocking portion, thereby preventing the mounting member from swinging about the swing axis past the position of the use state.

[0030] According to this structure, the component is installed at the position where the abutting part and the second blocking part abut, thus entering the use state.

[0031] Therefore, when the abutting part is in contact with the second blocking part, the mounting member remains in the working state, making it easy to change the locking mechanism from the unlocked state to the fixed state. Furthermore, by employing a structure where the abutting part is positioned between the mounting member and the second blocking part, damage to the mounting member is prevented.

[0032] In this invention, preferably, the mounting member is configured to swing about a swing axis extending in a horizontal direction, enabling state changes between the use state and the storage state, and the harvester has a handle mounted on the mounting member for swinging operation of the mounting member.

[0033] This structure improves the operability of the mounting components compared to structures without handles.

[0034] In this invention, preferably, the handle is installed in the mounting member at a position close to the swing shaft.

[0035] According to this structure, compared with a structure in which the handle is installed in the part near the free end of the mounting component, the operator can easily operate the handle from the driver's seat or the like.

[0036] In this invention, preferably, the mounting member is disposed on one side of the body in the left-right direction relative to the driver's seat, and the handle is mounted on the side of the mounting member located on the driver's seat side in the left-right direction of the body.

[0037] According to this structure, operators can easily operate the handle from the driver's seat.

[0038] In this invention, preferably, the mounting member is configured to be fixed in the stored state.

[0039] According to this structure, the stored state of the mounting components is securely maintained. Therefore, the risk of accidental damage to the mounting components and receiving device can be reduced while the harvester is being stored. Attached Figure Description

[0049] The following description uses a self-detaching combine harvester as an example to illustrate the harvester of this embodiment.

[0050] Figure 1 This is a left-side view of a combine harvester. Figure 2 This is a top view of a combine harvester. For ease of understanding, in this embodiment, unless otherwise stated, "front" (or "rear") will be used. Figure 1 The direction of the arrow "F" indicates the front of the aircraft in the forward / backward direction (direction of travel), and the rear ( Figure 1 The direction of arrow "B" indicates the rear of the aircraft in the forward / backward direction (direction of travel). Additionally, "up" ( Figure 1 The direction of the arrow "U" shown) and "down" ( Figure 1 The direction of the arrow "D" (as shown) represents the vertical position (perpendicular to the horizontal plane), indicating the height relationship on the ground. Furthermore, the left-right or lateral direction refers to the transverse direction of the aircraft (the width direction of the aircraft) orthogonal to the front-back direction. That is, "left" ( Figure 2 The direction of the arrow "L" shown) and "right" ( Figure 2 The arrows "R" (as shown) indicate the directions of the machine's left and right sides, respectively. Figure 3The same applies to the accompanying diagrams.

[0051] [Regarding the combine harvester as a whole]

[0052] like Figure 1 As shown, the combine harvester's running gear 1 has a frame 2, which is constructed from multiple steel strips, such as square tubing. A pair of tracked running gears 3 are mounted on the lower part of the frame 2. A driver's compartment 5 is located on the right side of the front of the running gear 1. The driver's compartment 5 houses the driver. Furthermore, this embodiment of the combine harvester is capable of automatic driving and automatic steering; therefore, the driver in the driver's compartment 5 includes both the driver who operates the combine harvester and the driver who does not operate it. An engine E is located below the driver's compartment 5. The driver's compartment 5 is not covered by a cab and is open to the outside.

[0053] A retractable harvesting section 4 is provided at the front of the traveling body 1. The harvesting section 4 has a plurality of dividers 4a and a plurality of lifting devices 4b. The harvesting section 4 harvests rice or wheat stalks (crops) from multiple planting rows while using the lifting devices 4b to lift them, and transports the harvested stalks to the rear of the machine. A threshing device 6 and a grain bin 8 are supported at the rear of the machine frame 2 in a transverse arrangement. The threshing device 6 is located behind the harvesting section 4, and the grain bin 8 is located behind the driving section 5. A feeding chain 7 is provided on the left side of the threshing device 6, which clamps and transports the harvested stalks from the harvesting section 4 to the rear. In the threshing device 6, the input harvested stalks are threshed, and the resulting grains and dust are sorted. The grain jar 8 stores the grains that have been threshed and transported from the threshing device 6. A conveying device 9 for removing grains from the grain jar 8 is connected to the rear of the grain jar 8.

[0054] The conveying device 9 has a longitudinal conveying section 9A and a transverse conveying section 9B. The longitudinal conveying section 9A is connected to the lower rear part of the grain tank 8 and longitudinally conveys the grains stored in the grain tank 8. The transverse conveying section 9B is connected to the upper end of the longitudinal conveying section 9A and transversely conveys the grains from the longitudinal conveying section 9A. A discharge port 9C is provided at the downstream end of the transverse conveying section 9B in the conveying direction. The transverse conveying section 9B conveys the grains from the longitudinal conveying section 9A to the discharge port 9C and discharges them from the discharge port 9C to the outside of the machine.

[0055] The lateral conveying unit 9B is configured to be able to move up and down and rotate left and right. For example... Figure 1 and Figure 2As shown, when the conveying device 9 is not in use, the transverse conveying section 9B extends forward and backward, positioned higher than the threshing device 6 and the grain bin 8, and spans the central portion of the machine body when viewed from above. This state of the transverse conveying section 9B is referred to as the "stored state." Furthermore, the position of the transverse conveying section 9B at this time is referred to as the "starting position."

[0056] When the conveying device 9 is used, the lateral conveying section 9B can extend outward from its stored state in the initial position to discharge grains. Here, "outside the machine body" refers to the left side of the left side of the threshing device 6 (lateral outer side of the machine body), the right side of the right side of the grain container 8 (lateral outer side of the machine body), and the rear side of the rear ends of both the threshing device 6 and the grain container 8. That is, when the conveying device 9 is used, the lateral conveying section 9B extends from the traveling body 1 to the side that moves to the left or right or rearward to discharge the grains stored in the grain container 8.

[0057] The combine harvester in this embodiment includes a satellite positioning receiver 20. The receiver 20 receives GNSS (Global Navigation Satellite System, such as GPS, GLONASS, Galileo, QZSS, and BeiDou) signals from navigation satellites (not shown) to obtain the vehicle's position. The receiver 20 is positioned offset to the left (left-right) side of the machine body relative to the left-right center of the driver's unit 5.

[0058] [Driver's Section]

[0059] The pilot's section 5 is configured with its position offset to the right of the fuselage relative to the center of the fuselage. For example... Figures 1-4 As shown, the driver's unit 5 includes 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 located in the central area of ​​the driver's unit 5. The driver sits in the driver's seat 11. A floor portion 15 is provided between the front panel 12 and the driver's seat 11 in the longitudinal direction. Figure 3 A step 14 is provided on the right side of the driver's seat 11 and the floor 15. The side panel 13 is located on the side opposite to the side where the step 14 is located in the driver's compartment 5.

[0060] The front panel 12 includes a steering lever 16 and an instrument panel (not shown). The steering lever 16, a control element for driving operations, is located at the right end of the front panel 12, in front of the driver's seat 11. The driver, seated in the driver's unit 5, can steer the driving device 3 by operating the steering lever 16. Additionally, the driver can raise and lower the harvesting unit 4 by operating the steering lever 16. In other words, the steering lever 16 handles both steering and operating operations. The instrument panel (not shown) displays, for example, driving speed, engine speed, and fuel level.

[0061] The side panel 13 includes a main shift lever 18. The main shift lever 18 is located at the front of the side panel 13. The main shift lever 18 is a lever that can be swung in the forward and backward direction. The driver, seated in the driver's seat 5, can operate the main shift mechanism (not shown) by operating the main shift lever 18.

[0062] Behind the driver's seat 11 is a box-shaped rear compartment 40. The rear compartment 40 protrudes upwards from the seat 11. The upper surface of the rear compartment 40 is at a height corresponding to the upper part of the backrest of the driver's seat 11. Although not described in detail, the rear compartment 40 houses an air filter for the intake of the engine E, an electronic control unit (ECU), and the like.

[0063] A driver's canopy 41 is provided above the driver's section 5. The driver's canopy 41 covers the driver's section 5 as a sunshade and rain shelter.

[0064] [Regarding the support structure of the receiving device]

[0065] In this embodiment, the receiving device 20 is supported by the mounting member 25, and the receiving device 20 and the mounting member 25 are pivotally supported by the supporting member 21. Figure 2 As shown, the receiving device 20 and the mounting component 25 are positioned on the left side of the fuselage relative to the pilot's seat 11. Figure 3 and Figure 4 As shown, the support member 21 of the support receiving device 20 and the mounting member 25 has a front and rear frame portion 22, a longitudinal frame portion 23, and a transverse frame portion 24.

[0066] The front and rear frame sections 22 extend in the front-rear direction when the fuselage is viewed from above or from the side. The longitudinal frame section 23 extends in the vertical direction. Furthermore, the longitudinal frame section 23 supports the mounting member 25 and the fulcrum member 26 at its upper part. The front and rear frame sections 22 are connected to the upper part of the longitudinal frame section 23 and extend from the longitudinal frame section 23 in a horizontal or substantially horizontal direction. That is, the front end of the front and rear frame sections 22 is connected to the upper end of the longitudinal frame section 23. The transverse frame section 24 extends laterally when the fuselage is viewed from above. The transverse frame section 24 is connected to the lower front part of the longitudinal frame section 23.

[0067] The support member 21, consisting of the front and rear frame portions 22, the longitudinal frame portion 23, and the transverse frame portion 24, forms an L-shape when viewed from above. Furthermore, the support member 21, consisting of the front and rear frame portions 22 and the longitudinal frame portion 23, forms a door-shaped structure when viewed from the side.

[0068] like Figure 3As shown, the fulcrum member 26 is fixed to the connection portion of the front and rear frame portions 22 and the longitudinal frame portion 23 by bolts. The mounting member 25 is pivotally supported by the fulcrum member 26. A receiving device 20 is installed at the free end of the mounting member 25. That is, the mounting member 25 is supported by the front and rear frame portions 22 and the longitudinal frame portion 23 via the fulcrum member 26 and is connected to support the receiving device 20.

[0069] The mounting component 25 is in an upward swinging state. Figure 1 The solid line indicates that the state of the mounting member 25 at this time corresponds to the "use state" described in the claims. The downward swinging state of the mounting member 25 is... Figure 1 The dashed line indicates the state. The state of the mounting member 25 at this time is equivalent to the "stored state" described in the claims. That is, the mounting member 25 is configured to swing about a swing axis X1 extending in the horizontal direction, and can change between the use state of using the receiving device 20 and the stored state in which the receiving device 20 is stored at a position lower than that in the use state.

[0070] When the mounting component 25 is switched to the usage state, compared to when the receiving device 20 is in the storage state, the receiving device 20 is less susceptible to multipath interference, resulting in better positioning accuracy during harvesting operations. Furthermore, when the mounting component 25 is switched to the storage state, even in cases where the ceiling of the storage silo for the combine harvester is low, interference between the ceiling and the receiving device 20 can be avoided.

[0071] Regardless of whether the mounting component 25 is in use or stored, the receiving device 20 is positioned further forward than the driving unit 5. When viewed from above, the receiving device 20 overlaps with the harvesting unit 4 and is located at the center of the left-right width of the harvesting unit 4. Figure 1 and Figure 2 As shown, the receiving device 20 is located at the top of the divider 4a and the rear of the lifting device 4b (in Figure 1 and Figure 2 The front-to-back width W is the range of the upper end of the lifting device 4b. Regardless of whether the mounting member 25 is in the use state or the storage state, the receiving device 20 is located within the range of the front-to-back width W.

[0072] The receiver 20 is located on the left side of the fuselage relative to the pilot unit 5. Furthermore, when the mounting member 25 is in use, the receiver 20 is generally positioned further forward than the pilot canopy 41. Additionally, when the mounting member 25 is in use, the receiver 20 can also be positioned further forward than the pilot canopy 41. Moreover, when the mounting member 25 is in use, the receiver 20 does not overlap with the pilot canopy 41 or the lateral transport section 9B in its stowed state when viewed from above.

[0073] like Figure 1 As shown, when the mounting member 25 is in use, the receiving device 20 is located at a higher position than the upper end of the lateral transport section 9B in the stored state. In addition, when the mounting member 25 is in the stored state, the receiving device 20 is positioned lower than the upper end of the lateral transport section 9B of the transport device 9 in the stored state, and is positioned further rearward than the front end of the lateral transport section 9B in the stored state.

[0074] Alternatively, when the mounting component 25 is in the retracted state, the upper end of the receiving device 20 may be at the same or approximately the same height as the upper end of the lateral transport section 9B in the retracted state.

[0075] When the mounting component 25 is in the retracted state, the receiving device 20 is located at the same or approximately the same height as the upper end of the support component 21 (specifically, the upper end of the front and rear frame portions 22). Furthermore, the abutment portion 25F (see reference) is adjusted using bolts. Figure 5 The position of the receiving device 20 (etc.) can be adjusted (height adjustment) during storage.

[0076] The front and rear frame sections 22 and the longitudinal frame section 23 are supported by the left side of the pilot section 5. In other words, the pilot section 5 is configured with its orientation offset to the right of the fuselage relative to the center of the fuselage, and the front and rear frame sections 22 are supported by the left and right central ends of the pilot section 5. The front of the front and rear frame sections 22 extends horizontally and longitudinally. When viewed from the side, the front of the front and rear frame sections 22 overlaps with the transverse transport section 9B in its stowed state (see reference). Figure 1 ).

[0077] The front and rear frame sections 22 have a rod section 22a extending front to rear, a corner plate member 22b at the front end, and a corner plate member 22c at the rear end. The corner plate member 22b is welded to the front end of the rod section 22a. The corner plate member 22c is welded to the rear end of the rod section 22a. The front and rear middle portions of the rod section 22a are curved. The bottom surface of the corner plate member 22c is bolted to the upper surface of the rear box 40. 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 slopes downwards and backwards. That is, the rod section 22a extends horizontally or approximately horizontally from the longitudinal frame section 23 and slopes downwards and backwards at its rear. In other words, the rear portion of the rod section 22a is vertically positioned in a forward-leaning posture on the left side of the rear portion of the driver's section 5. Furthermore, the rear portion of the rod section 22a slopes downwards and backwards, and when viewed from above, it is positioned further forward and closer to the right side of the fuselage. This avoids interference between the rod section 22a and the driver's canopy 41.

[0078] The front part of the horizontally extending rod section 22a and the corner plate member 22b do not overlap with the cockpit canopy 41 when the fuselage is viewed from above. In addition, the upper part of the longitudinal frame section 23, the mounting member 25, and the fulcrum member 26 do not overlap with the cockpit canopy 41 when the fuselage is viewed from above.

[0079] The longitudinal frame section 23 has a bar portion 23a extending vertically, a corner plate member 23b at the upper end, and a corner member 23c at the lower end. The corner member 23c is welded to the lower end of the bar portion 23a. The corner plate member 23b is welded to the upper end of the bar portion 23a. The left side portion of the corner member 23c, extending longitudinally along the left side of the fuselage, is bolted to the left side portion of the front portion of the side panel 13. In other words, the longitudinal frame section 23 is supported by the left side portion of the pilot section 5 (the left and right central ends of the pilot section 5). The bar portion 23a is vertically installed in a tilted posture (forward tilt posture) such that the higher it is, the more forward it is. Furthermore, the corner plate member 22b in the front and rear frame sections 22 and the corner plate member 23b in the longitudinal frame section 23 are bolted together. At this time, the lower surface portion of the corner plate member 22b and the upper surface portion of the corner plate member 23b abut against each other.

[0080] The left side of the left side of the angular member 23c extends vertically and forward and backward. A triangular portion is formed on this left side. The rear edge of this triangular portion is welded to the rod portion 23a both vertically and horizontally. That is, the longitudinal frame portion 23 is inclined in a way that it is located further forward of the body towards the upper side, and the angular member 23c is formed in a way that its front and rear widths increase towards the lower side when the body is viewed from the side. The distance between the front end and the rear end of the angular member 23c increases towards the lower side. This improves the rigidity of the rod portion 23a.

[0081] When viewed from above, the angular member 23c is bent into an L-shape. The L-shaped front end of the angular member 23c extends from the bent portion towards the right side of the fuselage. The front end of the angular member 23c has a forward-facing portion. This front end extends vertically and horizontally.

[0082] Furthermore, a flat surface portion along the horizontal direction is formed on the upper part of the angular member 23c. This flat surface portion is quadrilateral when viewed from above and connects to the upper ends of the front end portion and the left side portion of the angular member 23c, which are curved into an L-shape when viewed from above. This flat surface portion along the horizontal direction extends forward and backward and left and right. The angular member 23c is curved into an L-shape when viewed from above, and the left side portion of the angular member 23c is triangular when viewed from the side, and a flat surface portion connecting the front end portion and the left side portion is provided on the upper part of the angular member 23c. As a result, the angular member 23c is formed into a box shape, which improves the overall rigidity of the angular member 23c. Consequently, the rigidity of the rod portion 23a is improved.

[0083] Thus, the lower end of the longitudinal frame portion 23 has an angled member 23c for reinforcing the longitudinal frame portion 23. Alternatively, the angled member 23c may be provided in the portion above the lower end of the longitudinal frame portion 23, i.e., in the lower part of the longitudinal frame portion 23.

[0084] The rod portion 23a of the longitudinal frame section 23 and the rear portion of the rod portion 22a of the front and rear frame sections 22 are arranged vertically along the front-rear direction of the machine body. Thus, the front portion of the rod portion 22a in the front and rear frame sections 22 extends along the front-rear direction of the machine body.

[0085] The horizontal frame section 24 includes a bar portion 24a, a handrail frame portion 24b for the driver to hold onto when boarding or alighting from the boarding / alighting port 5A, a corner plate member 24c at the right end of the fuselage, and a flat plate member 24d at the left end of the fuselage. The bar portion 24a extends laterally along the fuselage when viewed from above. Furthermore, the bar portion 24a forms an L-shape when viewed from the front and rear. The bar portion 24a extends to both ends of the front panel 12 and extends downward from the right end. The left end of the bar portion 24a is welded to the flat plate member 24d.

[0086] The front portions of the flat plate member 24d in the transverse frame portion 24 and the angle member 23c in the longitudinal frame portion 23 are bolted together. That is, the longitudinal frame portion 23 and the transverse frame portion 24 are connected to each other through their flat surfaces. Thus, the longitudinal frame portion 23 and the transverse frame portion 24 are firmly connected with a simple structure. Specifically, the angle member 23c and the flat plate member 24d each have a flat surface, and the angle member 23c and the flat plate member 24d are connected to each other with their respective flat surfaces facing each other.

[0087] The corner plate member 24c is a member formed by bending a flat plate member. The upper end of the corner plate member 24c is bent into an L-shape when viewed from the front and rear of the machine. The corner plate member 24c is connected to the rod portion 24a and the handrail frame portion 24b at the right end of the cross frame portion 24, respectively. An upper surface portion is formed at the upper end of the corner plate member 24c. The right end of the rod portion 24a is welded to the upper surface portion of the corner plate member 24c. Furthermore, the handrail frame portion 24b is welded to the corner plate member 24c. Thus, the right end of the cross frame portion 24 has a handrail frame portion 24b.

[0088] The armrest frame portion 24b is connected to the outer side of the front panel 12. That is, the right end of the armrest frame portion 24 is supported by the outer side of the front panel 12 in the driver's compartment 5 and is adjacent to the boarding / alighting opening 5A of the driver's compartment 5.

[0089] In this way, the horizontal frame portion 24 is connected to the lower part of the vertical frame portion 23 in the front and rear frame portions 22 and the outer lateral end of the front panel 12, respectively, and extends along the left and right direction of the body. Thus, the front and rear frame portions 22 and the vertical frame portion 23 are firmly supported by the horizontal frame portion 24.

[0090] The cross frame 24 is positioned further forward than the steering lever 16. Furthermore, the cross frame 24 is positioned further downward than the upper end of the steering lever 16. Therefore, the driver, seated in the driver's seat 11, can easily identify the field in front of the aircraft without needing to pay attention to the cross frame 24.

[0091] Furthermore, the irradiation section 32 is supported by the corner plate member 24c. The irradiation section 32 irradiates the periphery of the right front part of the machine body. In addition, the irradiation section 32 can swing about the longitudinal axis. Therefore, for example, by an operator (including a driver) rotating the irradiation section 32 backward, the irradiation section 32 can irradiate the periphery of the right side of the driver's section 5.

[0092] An automatic driving operation unit 31 is bolted to the cross frame portion 24. In other words, the automatic driving operation unit 31 is supported by the cross frame portion 24. Although not shown, the combine harvester of this embodiment has a control device for performing automatic driving and automatic steering. The automatic driving operation unit 31 receives human input for outputting commands to the control device.

[0093] The automatic driving control unit 31 has a plurality of buttons associated with automatic steering and automatic driving. Therefore, for example, a driver can operate the automatic driving control unit 31 to enable the combine harvester to be automatically steered or driven. Furthermore, the control device can also be configured to perform at least one of automatic driving and automatic steering.

[0094] The automatic driving control unit 31 is positioned further outward and forward of the aircraft than the steering control lever 16. When viewed from above, the automatic driving control unit 31 does not overlap with the pilot canopy 41 located in the canopy position. The automatic driving control unit 31 and the illumination unit 32 overlap when viewed from above.

[0095] [Regarding the swing support structure for the mounting components]

[0096] based on Figures 5-8 The structure of the mounting member 25 will be described. 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 rotating portion 25A of the mounting member 25 is embedded in the swing bearing portion 26A of the fulcrum member 26, and the mounting member 25 swings about the swing axis X1 of the base end rotating portion 25A. Thus, the mounting member 25 swings about the swing axis X1 of the base end rotating portion 25A. Furthermore, a handle 42 for swinging the mounting member 25 is mounted on the mounting member 25.

[0097] like Figure 6 As shown, a cylindrical small-diameter portion 26P is formed on the right side of the body of the oscillating bearing portion 26A, and a cylindrical large-diameter portion 26Q is formed on the right side of the body of the oscillating 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 rotating portion 25A of the mounting member 25. Therefore, the base rotating portion 25A of the mounting member 25 can pass through the small-diameter portion 26P.

[0098] In addition, a stepped portion 26R is formed between the small diameter portion 26P and the large diameter portion 26Q.

[0099] The base rotating portion 25A of the mounting member 25 is inserted into the large-diameter portion 26Q, and the helical spring 27 and the bushing portion 28 are externally fitted into the base rotating portion 25A. One end of the helical spring 27 abuts against the stepped portion 26R, and the other end of the helical 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 in such a way that the base rotating portion 25A of the mounting member 25 extends along the swing axis X1.

[0100] A threaded groove 25S is formed at the rear end of the base rotating portion 25A of the mounting member 25, and the nut Nu is screwed into the threaded groove 25S. Additionally, a washer 29 is positioned between the bushing portion 28 and the nut Nu. In this state, the nut Nu is secured to the base rotating portion 25A of the mounting member 25.

[0101] A hole is formed in the base rotating part 25A of the mounting member 25 along a direction orthogonal to the swing shaft X1, and a locking pin 30 is inserted through this hole. The locking pin 30 abuts against the right side of the swing bearing part 26A, restricting the sliding movement of the mounting member 25 to the left of the body. When the locking pin 30 abuts against the right side of the swing bearing part 26A, the coil spring 27 is compressed. Therefore, the locking pin 30 is subjected to force in abutting against the right side of the swing bearing part 26A. Details will be explained later. A longitudinal groove 26V and a transverse groove 26H are formed on the right side of the swing bearing part 26A (see reference). Figure 8 The locking pin 30 can engage with the longitudinal groove 26V and the transverse groove 26H respectively. The longitudinal groove 26V and the transverse groove 26H are formed to intersect each other or substantially orthogonally. The locking pin 30, the longitudinal groove 26V and the transverse groove 26H are equivalent to the "positioning mechanism" described in the claims.

[0102] Mounting member 25 has a base end rotating part 25A, an arm part 25B, a mounting plate part 25C, a web part 25D, a base end bracket part 25E, and an abutment part 25F. One end of the arm part 25B is welded to the end of the base end rotating part 25A on the side where the driver's seat 11 is located.

[0103] A mounting plate 25C is welded to the other end of the arm 25B. A receiving device 20 is bolted to the flat surface of the mounting plate 25C. When the mounting member 25 is in the retracted state, the flat surface of the mounting plate 25C faces forward or forward-downward. When the mounting member 25 is in use, the flat surface of the mounting plate 25C faces upward.

[0104] The arm portion 25B is formed as a flat plate. The arm portion 25B has flat surface portions along the front-to-back and up-and-down directions. A flat web portion 25D is welded to the central portion along the length direction of the arm portion 25B. The web portion 25D extends along the length direction of the arm portion 25B. The web portion 25D has flat surface portions along the length direction of the arm portion 25B and the left-to-right direction of the fuselage. Therefore, the mounting member 25 is formed in a T-shape when viewed in cross-section along the length direction of the arm portion 25B and the web portion 25D. Furthermore, the web portion 25D is formed in a trapezoidal shape, tapering towards the left-to-right direction of the fuselage as it moves away from the swing axis X1. This improves the rigidity of the arm portion 25B and reduces the moment load when the mounting member 25 swings around the swing axis X1.

[0105] The base end bracket portion 25E is welded and fixed to the lower part of the web portion 25D and the base end rotating portion 25A, respectively. 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 along one end of the side where the receiving device 20 is located and the other end of the side opposite to the side where the receiving device 20 is located, sandwiching the base end rotating portion 25A. One end of the base end bracket portion 25E is bent into an L-shape and welded and fixed to the lower part of the web portion 25D. In addition, a welding nut is provided at one end of the base end bracket portion 25E, and an abutment portion 25F is installed on the welding nut. In addition, as will be explained in detail later, a retaining member 53 is connected to the area on the other end side of the base end bracket portion 25E.

[0106] The handle 42 has a gripping portion for the operator to hold. Bolt insertion portions are provided at both ends of the gripping portion of the handle 42 in the longitudinal direction. In the arm portion 25B, weld nuts are provided at both the base end and free end sides, across the welded portion to the web portion 25D. Bolts are inserted into the bolt insertion portions at both ends of the handle 42, and the two ends of the handle 42 are bolted to the weld nuts of the arm portion 25B. The web portion 25D is located between the two ends of the handle 42. The handle 42 is mounted on the side of the mounting member 25 on the side of the driver's seat 11 in the left-right direction of the machine body. Additionally, the handle 42 is mounted on the mounting member 25 near the swing shaft core X1.

[0107] The handle 42 swings integrally with the receiver 20 around the swing axis X1 of the receiver 20. For example, when the driver moves the handle 42 towards... Figure 5 When the device is swung clockwise, the mounting member 25 is in the working state, and the receiving device 20 swings upward together with the mounting member 25. Then, the receiving device 20 is positioned directly above the swing shaft X1. At this time, the handle 42 is positioned directly above or approximately directly above the swing shaft X1 when viewed from the shaft direction. Furthermore, the locking pin 30 is engaged with the transverse groove 26H on the right side of the body of the swing bearing portion 26A. Therefore, the angle of the mounting member 25 in the working state is firmly held by the transverse groove 26H.

[0108] For example, when the operator moves hand 42 towards Figure 5 During the counter-clockwise swing operation, the mounting member 25 swings forward and downward from its working position. At this time, the locking pin 30 is pulled out of the transverse groove 26H against the force of the coil spring 27. Then, the mounting member 25 is in the retracted state. In addition, the receiving device 20 swings downward together with the mounting member 25.

[0109] In this embodiment, the mounting member 25 has an abutment portion 25F that can abut against the corner plate member 23b. The head of the abutment portion 25F is made of an elastomer. A weld nut is fixed to the portion of the base bracket portion 25E that connects to the web portion 25D. The abutment portion 25F is bolted to this weld nut. The elastomer of the head of the abutment portion 25F is, for example, rubber, but may also be asbestos or polyurethane.

[0110] like Figure 5 As shown by the double-dotted line, when the receiving device 20 and the mounting member 25 swing downwards, the head of the abutment portion 25F abuts against the front surface of the corner plate member 23b. This abutment portion 25F and the corner plate member 23b abut against each other represents the retracted state of the mounting member 25. In other words, the support member 21 has the corner plate member 23b, which, by abutting against the mounting member 25, prevents the mounting member 25 from swinging past its retracted position about the swing axis X1. The front surface of the corner plate member 23b corresponds to the "first blocking portion" as described in the claims.

[0111] The abutment portion 25F has a bolt portion. By adjusting the position of this bolt portion, the distance between the welded nut in the base bracket portion 25E and the head of the abutment portion 25F can be adjusted. That is, the abutment portion 25F is configured to be position-adjustable. As a result, the position (height adjustment) of the receiving device 20 and the mounting member 25 when the mounting member 25 is in the retracted state can be performed.

[0112] In relation to mounting component 25 Figure 5 When the mounting member 25, as shown by the solid line in the usage state, is tilted forward and downward at a 90-degree angle, and the position of the abutment portion 25F is adjusted, the locking pin 30 is engaged with the longitudinal groove 26V in the right side of the body of the swing bearing portion 26A. Therefore, the angle of the mounting member 25 in the stored state is firmly held by the longitudinal groove 26V. Furthermore, in this embodiment, as... Figure 8 As shown, the longitudinal groove 26V and the transverse groove 26H are formed in a manner that intersects each other orthogonally or substantially orthogonally, but this embodiment is not limited to this one. For example, the structure could also be such that the longitudinal groove 26V and the transverse groove 26H intersect at an angle rather than orthogonally, so that the locking pin 30 can... Figure 5 The mounting component 25, in its stored state as indicated by the double-dotted line, is embedded at an angle into the longitudinal groove 26V.

[0113] In this embodiment, the fulcrum member 26 has a corner portion 26B, which is covered by an elastomer. When the mounting member 25 is in use, the head of the abutment portion 25F abuts against the front end of the corner portion 26B. In other words, the support member 21 has a corner portion 26B, which, by abutting against the mounting member 25, prevents the mounting member 25 from swinging past the position of the use state about the swing axis X1. The abutment portion 25F is configured to abut against the corner portion 26B. Moreover, by abutting against the corner portion 26B, the mounting member 25 is prevented from swinging past the position of the use state about the swing axis X1. In addition, the head and corner portion 26B of the abutment portion 25F are each made of an elastomer. As a result, the impact when the head and corner portion 26B of the abutment portion 25F abut against each other is mitigated, reducing the risk of breakage of the head and corner portion 26B of the abutment portion 25F respectively. The corner portion 26B corresponds to the "second preventing portion" as described in the claims. The elastomer covering corner 26B is, for example, rubber, but may also be asbestos or polyurethane, etc.

[0114] [Regarding the locking mechanism and retaining components]

[0115] like Figures 5-9 As shown, this embodiment includes a locking mechanism 50 and a retaining member 53. The locking mechanism 50 is a mechanism for holding the receiving device 20 in the use position. The locking mechanism 50 is configured to change between a fixed state in which the mounting member 25 is fixed in the use state and a released state in which the mounting member 25 is released from the use state. The retaining member 53 holds the locking mechanism 50 in the released state.

[0116] The locking mechanism 50 has a locking part 51 and a locked part 52. The locking part 51 has an L-shaped part 51A, a hook part 51B, a coil spring 51C, a washer 51D, and a locking pin 51E. The locked part 52 has a locked hole 52a and two bolt insertion holes 52b.

[0117] The retaining member 53 is connected to the base bracket portion 25E. The retaining member 53 has a cylindrical rod-shaped portion 53A and a flat plate-shaped portion 53B. The cylindrical rod-shaped portion 53A of the retaining member 53 protrudes from the base bracket portion 25E toward the side where the driving portion 5 is located. The flat plate-shaped portion 53B of the retaining member 53 is welded and fixed to the central portion along the length direction of the cylindrical rod-shaped portion 53A. A circular hole 53h is perforated in the flat plate-shaped portion 53B of the retaining member 53, and the locking portion 51 of the locking mechanism 50 is inserted into the circular hole 53h.

[0118] The right end of the side containing the mounting member 25 in the L-shaped part 51A extends along the left-right direction of the machine body. The left end of the side opposite to the side containing the mounting member 25 in the L-shaped part 51A is bent into an L-shape.

[0119] An insertion hole is formed on the base bracket portion 25E, which overlaps with the circular hole 53h of the flat portion 53B when viewed from the side of the body. The right end of the L-shaped portion 51A is inserted into the circular hole 53h and the insertion hole of the base bracket portion 25E.

[0120] A coil spring 51C and a washer 51D are externally fitted into the right end of the L-shaped portion 51A, located between the flat portion 53B and the base bracket portion 25E. A through hole for a locking pin 51E is formed at the right end of the L-shaped portion 51A. With the coil spring 51C and washer 51D externally fitted into the right end of the L-shaped portion 51A, the locking pin 51E is inserted into the through hole. The washer 51D is always positioned closer to the right side of the machine body (away from the locked portion 52) than the locking pin 51E. Furthermore, the coil spring 51C is compressed by being sandwiched 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, the coil spring 51C exerts a force on the L-shaped portion 51A, causing it to shift to the right side of the machine body.

[0121] The hook portion 51B is welded and fixed between the right and left ends of the L-shaped portion 51A. By rotating the L-shaped portion 51A around the transverse axis of the machine body, the hook portion 51B is configured to abut against the round rod-shaped portion 53A of the retaining member 53.

[0122] The locking part 52 is fixed to the angle plate member 23b by bolts. The bolts are inserted into two bolt insertion holes 52b formed in the locking part 52, and are tightened to welded nuts on the angle plate member 23b. The inner diameter of the bolt insertion holes 52b is larger than the outer diameter of the bolts. Therefore, the position of the locking part 52 relative to the angle plate member 23b can be adjusted. Operators can install the locking part 52 onto the angle plate member 23b by inserting the right end of the L-shaped part 51A through the locking hole 52a.

[0123] When the mounting component 25 is in use, if the right end of the L-shaped portion 51A is inserted through the locking hole 52a, the locking mechanism 50 becomes fixed in the use state, securing the mounting component 25. 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 force of the coil spring 51C.

[0124] To change the locking mechanism 50 from the locked state to the unlocked state, the operator pulls the L-shaped part 51A towards the side where the driver's part 5 is located, overcoming the force of the coil spring 51C. The right end of the L-shaped part 51A is then pulled out of the locking hole 52a. Next, the operator rotates the L-shaped part 51A around the transverse axis of the machine body, causing the hook part 51B to abut against the cylindrical part 53A of the retaining member 53. The extended end of the cylindrical part 53A is tapered, with its diameter decreasing towards the tip. Furthermore, an engaging hole is formed in the hook part 51B, which engages with the tapered extended end of the cylindrical part 53A. At this time, the right end of the L-shaped part 51A is pulled out of the locking hole 52a, and the locking part 51 is held hooked onto the retaining member 53 by the force of the coil spring 51C. Thus, the locking mechanism 50 is unlocked. At this time, retaining member 53 keeps locking mechanism 50 in the released state.

[0125] To change the locking mechanism 50 from its current state to its fixed state, the operator overcomes the force of the coil spring 51C and pulls the L-shaped part 51A towards the side where the driver's part 5 is located, rotating the L-shaped part 51A until the hook part 51B is at an angle that is not hooked on the extended end of the rod-shaped part 53A. Then, when the operator releases the L-shaped part 51A from their hand, the right end of the L-shaped part 51A is inserted into the locking hole 52a by the force of the coil spring 51C, and the locking mechanism 50 is fixed.

[0126] When the mounting member 25 is in use and the locking mechanism 50 is in the released state, the locking pin 30 engages with the transverse groove 26H in the right end of the swing bearing portion 26A. Thus, the angle of the arm portion 25B when the mounting member 25 is in use is securely maintained by the locking pin 30 and the transverse groove 26H (see reference). Figure 8 Therefore, even if the locking mechanism 50 changes to the unlocked state, it can prevent the receiving device 20 and the mounting member 25 from falling due to their own weight when the operator does not operate it using the handle 42. In this way, the positioning mechanism (locking pin 30 and transverse groove 26H) is configured separately from the locking mechanism 50 to position the mounting member 25 in the use state.

[0127] like Figure 6 As shown, the base rotating portion 25A of the mounting member 25 is embedded in the swing bearing portion 26A of the fulcrum member 26, and the base rotating portion 25A and the swing bearing portion 26A sandwich the arm portion 25B and are located on the opposite side of the driver's seat 11. Therefore, the locking mechanism 50 and the positioning mechanism (locking pin 30 and transverse groove portion 26H) are separately arranged on one side and the other side relative to the mounting member 25 in the swing shaft X1 direction.

[0128] [Other Implementation Methods]

[0129] The present invention is not limited to the structures illustrated in the above embodiments. Hereinafter, other representative embodiments of the present invention are illustrated.

[0130] (1) The mounting member 25 is configured to swing up and down around the swing axis X1, and can change its state between the use state and the storage state. Not limited to this embodiment, the mounting member 25 may also be configured to change its state between the use state and the storage state by sliding up and down.

[0131] (2) The swing shaft X1 of the mounting member 25 extends in the left-right direction of the machine body. Not limited to this embodiment, the swing shaft X1 of the mounting member 25 may also be a structure that extends in the front-back direction of the machine body. That is, the mounting member 25 can be a structure that swings around the swing shaft X1 that extends in the horizontal direction.

[0132] Furthermore, the term "horizontal direction" as used in the claims is not limited to the strictly horizontal meaning, but also includes the meaning of a generally horizontal direction.

[0133] (3) In the above embodiment, the locking part 52 is connected to the arm part 25B, but it may also be a structure without the locking part 52. In this case, the front end of the L-shaped part 51A in the locking part 51 may contact the lower edge of the arm part 25B on the rotation track of the arm part 25B. In this state, the mounting member 25 is fixed in use by being supported from below by the locking part 51.

[0134] (4) In the above embodiment, a positioning mechanism (locking pin 30 and transverse groove 26H) is provided to position the mounting member 25 in the use state. However, it is also possible that the positioning mechanism only has the transverse groove 26H for positioning the mounting member 25 in the use state, without the longitudinal groove 26V. Alternatively, it may be possible to have a structure without a positioning mechanism. In the absence of a positioning mechanism, it is also possible to have a structure in which the mounting member 25 does not rotate due to its own weight by applying, for example, sliding friction during rotation to the base end rotating part 25A that engages with the swing bearing part 26A.

[0135] (5) In the above embodiment, the locking mechanism 50 and the positioning mechanism (locking pin 30 and transverse groove 26H) are arranged on the same side relative to the mounting member 25 in the direction of the swing shaft X1.

[0136] Not limited to this embodiment, the locking mechanism 50 and the positioning mechanism may also be separated by the mounting member 25.

[0137] (6) It may also be a structure having only one of the first blocking part (the front part of the corner plate member 23b) and the second blocking part (corner part 26B). Alternatively, it may be a structure that does not have both the first blocking part and the second blocking part, and in this case, it may also be a structure that does not have the abutment part 25F.

[0138] (7) Both the first stopping part (the front part of the corner plate member 23b) and the second stopping part (corner part 26B) may be made of an elastic body. In this case, the abutment part 25F may be made of a non-elastic body. Alternatively, both the first stopping part and the second stopping part may be made of a non-elastic body.

[0139] (8) The structure may be such that the handle 42 for swinging operation of the mounting member 25 is not mounted on the mounting member 25. In this case, the structure may also have a linkage mechanism or wire connection mechanism between the handle 42 and the mounting member 25. Alternatively, the structure may not have a handle 42.

[0140] (9) In the above embodiment, the locking mechanism 50 fixes the mounting component 25 in the use state.

[0141] Not limited to this embodiment, for example, it may be configured to have a second locking mechanism different from the locking mechanism 50, which can fix the mounting member 25 in the stored state. In this case, the mounting member 25 is configured to be fixed in the stored state.

[0142] Furthermore, the structures disclosed in the above embodiments (including other embodiments, the same below) can be combined with the structures disclosed in other embodiments as long as they do not create contradictions.

[0143] Furthermore, the embodiments disclosed in this specification are merely illustrative, and the embodiments of the present invention are not limited thereto, and appropriate changes can be made without departing from the purpose of the present invention.
