[0024] An engine room 6 that houses an engine E is provided below the control unit 5, a grain tank 7 that stores threshed and sorted grains is provided behind the control unit 5, and a discharge auger 8 consisting of a vertically extending grain lifting section and a horizontal discharge section that extends back and forth to discharge grains to the outside is provided behind the grain tank 7. The control unit 5 is also covered by a cabin 9 that has an illumination light on top.

[0025] As shown in Figure 3, the frame 10 that forms the cabin 9 is made up of a left frame 11, a right frame 12, a rectangular connecting frame (referred to as the "first connecting frame" in the claims) 13 that connects the front portions of the left frame 11 and the right frame 12, and a plurality of connecting frames (referred to as the "second connecting frames" in the claims) 14 that extend in the left-right direction and connect the rear portions of the left frame 11 and the right frame 12.

[0026] 4, the left frame 11 is formed of left upper and lower frames 15A-15D extending in the up-down direction and left front and rear frames 16A-16E extending in the front-rear direction. In this specification, the left upper and lower frames 15A-15D are collectively referred to as the left upper and lower frames 15, and the left front and rear frames 16A-16E are collectively referred to as the left front and rear frames 16.

[0027] The left front-rear frame 16A is connected to the upper part of the left vertical frame 15A and the left vertical frame 15D, and its front part extends forward from the left vertical frame 15A. The left front-rear frame 16B is connected to the upper part of the left vertical frame 15A and the left vertical frame 15A. The left front-rear frame 16C is connected to the middle part of the left vertical frame 15A and the lower part of the left vertical frame 15C and the left vertical frame 15D. The left front-rear frame 16D is connected to the middle part of the lower part of the left vertical frame 15A and the middle part of the left vertical frame 15B, and extends rearward from the left vertical frame 15B. The left front-rear frame 16E is connected to the lower part of the left vertical frame 15A and the left vertical frame 15B, and its front part extends forward from the left vertical frame 15A and its rear part extends rearward from the left vertical frame 15B. This increases the rigidity of the left frame 11, and suppresses deformation of the left frame 11.

[0028] 5, the right frame 12 is formed from upper right and lower frames 17A-17C extending in the up-down direction, right front and rear frames 18A, 18B extending in the front-rear direction, and a right curved frame 19 connecting the lower part of the upper right and lower frame 17C to the rear part of the right front and rear frame 18B. Note that in this specification, the upper right and lower frames 17A-17C are collectively referred to as the upper right and lower frame 17, and the right front and rear frames 18A, 18B are collectively referred to as the right front and rear frame 18.

[0029] The right front-rear frame 18A is connected to the upper parts of the upper right-lower frame 17A and the upper right-lower frame 17B, and its front part extends forward beyond the upper right-lower frame 17A. The right front-rear frame 18B is connected to the lower parts of the upper right-lower frame 17A and the right curved frame 19. In addition, the upper right-lower frame 17B is connected to the front part of the rear side of the right front-rear frame 18A and the right curved frame 19. This increases the rigidity of the right frame 12, and makes it possible to suppress deformation of the right frame 12.

[0030] 4 and 5, the left connecting frame 13L extending in the front-rear direction of the connecting frame 13 is connected to the lower parts of the left upper and lower frames 15A and the left upper and lower frames 15B. The right connecting frame 13R extending in the front-rear direction of the connecting frame 13 is connected to the lower parts of the right upper and lower frames 17A and the right curved frame 19. In addition, the connecting frame 14 is connected to the left front-rear frame 16C and the rear part of the right curved frame 19. This firmly connects the left frame 11 and the right frame 12 to increase the rigidity of the frame 10, thereby suppressing deformation of the frame 10.

[0031] The upper part of a rectangular parallelepiped storage box 20 with an open top is fixed to the inner periphery of the connecting frame 13. A battery 20A, a pump 20B, etc. are stored in the storage space of the storage box 20, and an opening formed in the right wall of the storage box 20 is fitted with a staircase-like step (not shown) that a worker can use when ascending or descending.

[0032] A partition member 21 that separates the cockpit 5 from the engine room 6 is provided at the rear of the frame 10. A support member 22 that supports a cockpit used by an operator is provided at the front of the partition member 21, and a convex portion 23 that is formed at the left side of the partition member 21 by bending the partition member 21 upward and opening the left side and bottom side. This allows the front portion of an exhaust purification device (DPF) that purifies impurities contained in the exhaust gas exhausted from the engine E to be inserted into the convex portion 23 and positioned therein.

[0033] The partition member 21 is formed of a portion 21A extending upward from a lower end portion detachably fixed to the rear portion of the connecting frame 13, a portion 21B extending upward and rearward from an upper end portion of the portion 21A, a portion 21C extending gently upward and rearward from an upper end portion of the portion 21B, a portion 21D extending upward from an upper end portion of the portion 21C, and a portion 21E extending upward and rearward from an upper end portion of the portion 21D. The rear end portion of the portion 21E is detachably fixed to the connecting frame 14.

[0034] As shown in FIG. 6, the left upper and lower frame 15A extends upward from the lower end connected to the connecting frame 13, then curves upward toward the left side, then curves upward, and then extends upward. Similarly, the left upper and lower frame 15B extends upward from the lower end, then curves upward toward the left side, then curves upward, and then extends upward. This allows a large space to be formed to the left of the cockpit of the control unit 5, and reduces the stress of the operator caused by the narrow space. In addition, the right upper and lower frame 17A extends upward from the lower end connected to the connecting frame 13.

[0035] A plate-shaped left wall 25 is provided on the left frame 11, and the left wall 25 is formed from a portion 25A extending downward along the left frame 11, a portion 25B extending downward to the right from the lower end of portion 25A, and a portion 25C extending downward from the lower end of portion 25B.

[0036] A window (not shown) is provided in a rectangular opening formed in the upper part of the portion 25A, and the lower end of the portion 25C abuts against the connecting frame 13. In addition, a plate-shaped cover member 26 extending upward and to the left from the upper surface of the connecting frame 13 is provided on the lower part of the portion 25A, the portion 25B, and the portion opposite the portion 25C.

[0037] The right frame 12 is provided with a plate-shaped right wall 27, and a rectangular opening portion formed in an upper portion of the right wall 27 is provided with a window (not shown).

[0038] 7 to 10, a support portion ("first support portion" in claims) 30 provided at the front of the vehicle frame 1 is provided below the front connecting frame 13A of the connecting frame 13. The support portion 30 is formed of a left-right support member 30A extending in the left-right direction and disposed below the front connecting frame 13A, a left upper and lower support member 30L extending from the left portion of the left-right support member 30A to the vehicle frame 1, and a right-right lower support member 30R extending from the right portion of the left-right support member 30A to the vehicle frame 1. The support portion 30 is provided forward of an output shaft 36A of a transmission 36.

[0039] The lower surface of the front connecting frame 13A and the upper surfaces of the left and right support members 30A are connected via a pair of left and right vibration isolating members such as vibration isolating rubber or shock absorbers ("first vibration isolating members" in claims) 31, which are provided at a predetermined interval in the left and right direction. This makes it possible to suppress vibrations generated in the vehicle frame 1 during travel, etc. from being transmitted to the front connecting frame 13A via the left and right support members 30A, thereby suppressing shaking of the cabin 9.

[0040] Additionally, an oil filter 33 is attached to the middle portion of the lower surface of the left and right support members 30A to remove impurities from the oil supplied to the hydraulic continuously variable transmission 32 that increases or decreases the output rotation of the engine E. This makes it easy to arrange a flexible hose that connects the continuously variable transmission 32 and the oil filter 33.

[0041] A support portion (a "second support portion" in the claims) 35 provided at the front of the vehicle frame 1 is provided below the left front-rear frame 16D. The support portion 35 is formed of a front-rear support member 35A extending in the front-rear direction and disposed below the left front-rear frame 16D, a front vertical support member 35F extending from the front of the front-rear support member 35A to a transmission 36 that increases or decreases the output rotation of the continuously variable transmission 32 disposed at the front of the vehicle frame 1, and a rear vertical support member 35B extending from the rear of the front-rear support member 35A to the transmission 36. This shortens the lengths of the front vertical support member 35F and the rear vertical support member 35B to increase the rigidity of the support portion 35 and prevent deformation of the support portion 35.

[0042] The lower surface of the left front-rear frame 16D and the upper surface of the front-rear support member 35A are connected via a vibration isolating member such as a vibration isolating rubber or a shock absorber (referred to as a "second vibration isolating member" in the claims) 37. This makes it possible to suppress vibrations generated in the aircraft frame 1 during travel, etc. from being transmitted to the left front-rear frame 16D via the front-rear support member 35A, thereby suppressing shaking of the cabin 9.

[0043] A support portion (a "third support portion" in the claims) 38 is provided at the rear of the front side of the vehicle frame 1 on the lower side of the connecting frame 14. The support portion 38 is formed of a left-right support member 38A extending in the left-right direction and disposed on the lower side of the connecting frame 14, a left upper-lower support member 38L extending from the left part of the left-right support member 38A to the vehicle frame 1, and a right-right lower support member 38R extending from the right part of the left-right support member 38A to the vehicle frame 1. In addition, left-right reinforcing members 38D extending in the left-right direction are provided at the lower part of the upper side of the left upper-lower support member 38L and the right-right lower support member 38R. This increases the rigidity of the support portion 38, and prevents deformation of the support portion 38.

[0044] The lower surface of the connecting frame 14 and the upper surfaces of the left and right support members 38A are connected via a pair of left and right vibration isolating members 39 such as vibration isolating rubber or shock absorbers ("third vibration isolating members" in the claims) that are provided at a predetermined interval in the left and right direction. This makes it possible to suppress vibrations generated in the aircraft frame 1 during travel, etc. from being transmitted to the connecting frame 14 via the left and right support members 38A, thereby suppressing shaking of the cabin 9.

[0045] In a plan view, vibration-isolating member 31, vibration-isolating member 37, and vibration-isolating member 39 are provided in this order from the front. Vibration-isolating member 37 is provided to the left of vibration-isolating members 31 and 39, and is located at the center in the left-right direction of transmission 36. Vibration-isolating member 39 is offset to the left of vibration-isolating member 31, i.e., the left-side vibration-isolating member 39 is provided to the left of the left-side vibration-isolating member 31, and the right-side vibration-isolating member 39 is provided to the left of the right-side vibration-isolating member 31. In addition, the distance between the left-side vibration-isolating member 39 and the right-side vibration-isolating member 39 is wider than the distance between the left-side vibration-isolating member 31 and the right-side vibration-isolating member 31.

[0046] It is preferable that vibration-isolating members 37 and 39 are made of vibration-isolating rubber that is larger than that of vibration-isolating member 31. This makes it possible to suppress vibrations of the left front-rear frame 16D and connecting frame 14, which have larger amplitudes due to vibrations in the front-rear and left-right directions than the front connecting frame 13A.

[0047] In a side view, the vibration-isolating member 31 is provided above the transmission 36, the vibration-isolating member 37 is provided above the vibration-isolating member 31, and the vibration-isolating member 39 is provided above the vibration-isolating member 37. The vibration-isolating member 37 is preferably provided at a position on an imaginary line connecting the vibration-isolating member 31 and the vibration-isolating member 39. This makes it possible to further suppress the vibrations generated in the vehicle frame 1 during traveling, etc. from being transmitted to the frame 10 via the left and right support members 30A, the front and rear support members 35A, and the left and right support members 38A, thereby further suppressing the shaking of the cabin 9, and also makes it possible to quickly attenuate the vibrations transmitted to the frame 10.

[0048] 11, a rectangular opening 41 for maintenance work is formed in the lower front part of the right wall of the cabin 9, facing a parking brake pedal 40 that brakes the traveling device 2. This allows easy maintenance work on the parking brake pedal 40 to be performed through the opening 41. Note that the opening 41 is normally covered with a rectangular cover 42.

[0049] As shown in FIGS. 12 and 13, a front panel 45 is provided in front of the cockpit of the control section 5, and a side panel 50 is provided on the left side.

[0050] The front panel 45 is provided with a monitor 46 that displays the traveling speed of the traveling device 2 and the output rotation of the engine E. In addition, an operating lever (not shown) for rotating the traveling device 2 and raising and lowering the reaping device 3 is provided on the right side of the monitor 46.

[0051] The left portion of the side panel 50 is provided adjacent to the left front / rear frame 16D that supports the left wall of the cabin 9. A speed change lever 51 for operating the continuously variable transmission 32 is provided at the front portion of the side panel 50, an emergency stop switch ("switch" in the claims) 52 for emergency stopping the engine E is provided behind the speed change lever 51, and to the right of the emergency stop switch 52 is a reaping / threshing lever 53 for operating a reaping clutch that transmits the output rotation of the engine E to the reaping device 3 and a threshing clutch that transmits the output rotation of the engine E to the threshing device 4.

[0052] The emergency stop switch 52 is provided in a recess 55 of the side panel 50, and the top of the emergency stop switch 52 is provided at approximately the same position as the upper surface of the side panel 50. This makes it possible to prevent the emergency stop switch 52 from being pressed accidentally.

[0053] In a side view, the front wall of the recess 55 is formed with a front-upward incline, and the rear wall is formed with a rear-upward incline. In addition, in the front-to-rear direction, the emergency stop switch 52 is moved forward and provided rearward from the grip portion of the mowing / removal lever 53 in a front-side inclined position, and moved rearward and provided rearward from the grip portion of the mowing / removal lever 53 in a rear-side inclined position. This allows the emergency stop switch 52 to be pressed quickly if the engine E overheats, for example. [Explanation of symbols]
