[0023] As shown in Figures 1-3, the general-purpose combine harvester has a running device 2 consisting of a pair of left and right crawlers that travel on the soil surface on the underside of the machine frame 1, a pre-harvest processing device 3 for harvesting grain stalks in the field is provided on the front of the machine frame 1, a threshing device 4 for threshing and sorting the harvested grain stalks is provided on the rear left side of the pre-harvest processing device 3, and a control unit 5 for the operator is provided on the rear right side of the pre-harvest processing device 3.

[0024] An engine room 6 housing the engine E is located below the control unit 5, a grain tank (the "storage tank" in the claims) 7 for storing threshed and sorted grain is located behind the control unit 5, and a discharge auger 8 for discharging the grain to the outside is located behind the grain tank 7. A sun visor 9 for blocking direct sunlight is also provided above the control unit 5.

[0025] The pre-harvesting processing device 3 consists of a raking device 3A that transports the grain stalks in the field to the rear while standing them upright, a cutting blade device 3B that cuts the base of the grain stalks transported behind the raking device 3A, an auger device 3C that gathers the transported grain stalks to the left, and a feeder house 3D that transports the gathered grain stalks to the threshing device 4.

[0026] As shown in Figure 4, a front panel 11 is provided in front of the operator's seat 10 of the control unit 5. A touch panel monitor 12 that displays the travel speed of the travel device 2 and the output rotation of the engine E is provided in the center of the front panel 11, and an operating lever 13 for operating the turning of the travel device 2 and the raising and lowering of the pre-harvesting device 3 is provided on the right side.

[0027] A side panel 15 is provided to the left of the operator's seat 10. A main shift lever 16 is provided at the front of the side panel 15 for operating the continuously variable transmission that increases and decreases the output speed of the engine E and switches the direction of rotation. A sub-shift lever 17 is provided behind the main shift lever 16 for operating the transmission that increases and decreases the output speed of the continuously variable transmission.

[0028] Furthermore, to the left of the main transmission lever 16 is an auger lever 18 for operating the auger clutch, which transmits the output rotation of the engine E to the discharge auger 8, and to the left of the sub-transmission lever 17 is a harvesting lever 19 for operating the harvesting clutch, which transmits the output rotation of the engine E to the harvesting pre-treatment device 3, and the threshing clutch, which transmits the output rotation of the engine E to the threshing device 4.

[0029] As shown in Figure 5, a cooling fan 21 is provided between the engine E in the engine compartment 6 and the radiator cover 20, which draws in air from outside the radiator cover 20 through the filter element of the radiator cover 20.

[0030] A pump 22 for supplying oil to the continuously variable transmission and other components is located above the engine E. In a plan view, the left side of the pump 22 is recessed inward from the outer circumference of the cooling fan 21. This allows for efficient cooling of the pump 22.

[0031] As shown in Figure 6, a connecting member 30 extending in the vertical direction is formed at the rear of the sun visor 9. The connecting member 30 is supported by a support member 31 that also extends in the vertical direction, allowing it to move vertically. The support member 31 is fixed to the front wall of the grain tank 7. This allows the vertical position of the sun visor 9 to be adjusted to suit the worker's physique.

[0032] <Fan device of the first embodiment> As shown in Figures 7 and 8, a fan device 40 of the first embodiment is provided on the rear right side of the operator's seat 10 to blow air towards the worker seated in the operator's seat 10. This lowers the worker's perceived temperature and improves the harvesting work environment.

[0033] The fan device 40 is formed from a fan 41 and a support member 42 that supports the fan 41. The support member 42 consists of a first support member 42A that extends in the vertical direction and the first support member 42A It is formed from a second support member 42B that extends from the top toward the center of the rear surface of the fan 41. The lower part of the first support member 42A is rotatably supported on the upper part of the rear surface of the rear of the radiator cover 20. This allows the first support member 42A to be rotated around its axis to easily direct the fan 41 toward the operator and blow air toward the operator. The fan switch 14A and the DC12V power supply 14B that drive the fan 41 are located between the operator's seat 10 and the radiator cover 20. This allows the fan 41 to be easily driven by operating the fan switch 14A.

[0034] <Fan device of the second embodiment> Figure 9 shows the fan device 40 of the second embodiment. Furthermore, the same reference numerals are used for components identical to those in the fan device 40 of the first embodiment, and their descriptions are omitted.

[0035] The fan device 40 of the second embodiment is formed from a fan 41 and a support member 42 that supports the fan 41. The support member 42 is formed from a first support member 42A that extends in the vertical direction, a second support member 42B that extends from the upper part of the first support member 42A toward the fan 41, and a third support member 42C that extends from the front part of the second support member 42B toward the center of the rear surface of the fan 41. The lower part of the first support member 42A is rotatably supported on the upper part of the rear surface of the rear of the radiator cover 20, and the second support member 42B is provided above the outer circumference of the fan 41. This makes it possible to rotate the first support member 42A around its axis to easily direct the fan 41 toward the worker and blow air toward the worker, and also prevents the fan 41 from coming into contact with external trees or fences, thereby suppressing damage to the fan 41 due to contact.

[0036] <Fan device of the third embodiment> Figures 10 and 11 illustrate the fan device 40 of the third embodiment. Furthermore, the same reference numerals are used for components identical to those in the fan device 40 of the first embodiment, and their descriptions are omitted.

[0037] The fan device 40 of the third embodiment is formed from a fan 41 and a support member 42 that supports the fan 41. The support member 42 is formed from a first support member 42A that extends upward and backward, and a second support member 42B that extends from the upper part of the first support member 42A toward the center of the rear surface of the fan 41. The front part of the first support member 42A is connected to the rear of the operator's seat 10. As a result, when the operator moves the operator's seat 10 in the forward and backward directions, the fan 41 moves in the forward and backward directions in conjunction with the operator's seat 10, maintaining a constant distance between the operator and the fan 41, and maintaining the strength of the air blown from the fan 41 toward the operator at a predetermined strength. Furthermore, the lower part of the second support member 42B is rotatably supported on the upper part of the first support member 42A. As a result, the second support member 42B can be rotated around its axis to easily direct the fan 41 toward the operator and blow air toward the operator.

[0038] <Fan device of the fourth embodiment> Figures 12-14 illustrate the fan device 40 of the fourth embodiment. Furthermore, the same reference numerals are used for components identical to those in the fan device 40 of the first embodiment, and their descriptions are omitted.

[0039] The fan device 40 of the fourth embodiment consists of a fan 41 and a support box 43 that surrounds the outer periphery of the fan 41 and is formed in a rectangular shape when viewed from the axis of the fan 41. In a front view, the fan 41 is located above the operator's seat 10.

[0040] The outer periphery of the support box 43 is fitted into a rectangular opening formed on the right side of the upper part of the front wall of the grain tank 7. This allows the cleaner 51 and the like to be efficiently arranged in the space formed behind the control unit 5. In this embodiment, the fan device is provided on the front wall of the grain tank 7, but if a hopper is installed instead of the grain tank 7, it can be provided on the front wall of the hopper (the "storage tank" in the claim).

[0041] In a plan view, a ventilation passage 44 is formed on the rear side of the support box 43 of the grain tank 7 to guide the air from outside the grain tank 7, and the left wall 44A of the ventilation passage 44 extends toward the rear right. This allows the fan 41 to rotate to efficiently draw in air and blow it toward the worker. Preferably, the intersection angle between the front wall and the left wall 44A of the grain tank 7 is formed at 45 degrees.

[0042] A filter 45 is provided at the air intake of the ventilation passage 44 located on the right wall of the grain tank 7. This allows for the removal of impurities such as straw debris from the air blown towards the workers.

[0043] As shown in Figure 15, the air that has passed through the pre-cleaner 50 has impurities removed by a cleaner 51 located behind the operator's seat 10, and is then drawn into the engine E via a flexible hose 52 and mixed with diesel fuel.

[0044] The exhaust gas from engine E is discharged to the outside through the rear of the tailpipe 55 via the exhaust pipe 53, a silencer 54 connected to the rear of the exhaust pipe 53 to reduce exhaust noise, and a tailpipe 55 connected to the rear of the silencer 54. A heat shield cover 56 is also provided on the upper side of the tailpipe 55.

[0045] As shown in Figure 16, in a side view, the pre-cleaner 50 is positioned behind the operator's seat 10 and below the top of the backrest of the operator's seat 10. This suppresses the transmission of noise generated by the pre-cleaner 50 to the operator.

[0046] As shown in Figure 17, a left vertical frame 60 and a right vertical frame 61 are provided at the rear of the control unit 5, extending from the aircraft frame 1, and the upper parts of the left vertical frame 60 and the right vertical frame 61 are connected by a horizontal frame 62 that extends in the left-right direction.

[0047] A support arm 63 extending forward is provided in the middle of the horizontal frame 62, and an opening for inserting the hose 52 is formed in the support arm 63. This suppresses the flapping of the hose 52 and also makes routing easier.

[0048] Below the connection point of the horizontal frame 62 on the left vertical frame 60, there is a lower clamping arm 65 extending to the left to support the lower part of the silencer 54, and an upper clamping arm 66 extending to the left to press against the upper part of the silencer 54. This allows the silencer 54 to be easily attached to and detached from the left vertical frame 60 during maintenance. [Explanation of Symbols]
