[0020] [Figure 1] This is a left side view of a combine harvester according to an embodiment of the present invention. [Figure 2] This is a plan view of the main components of a combine harvester. [Figure 3] This is a rear view of the main components of a combine harvester. [Figure 4] This is a perspective view of the main parts of a combine harvester. [Figure 5] This is a side view of the main components of a combine harvester. [Modes for carrying out the invention]

[0021] Hereinafter, a combine harvester 1, which is one embodiment of the present invention, will be described with reference to the attached drawings. For the sake of ease of understanding, directions will be conveniently indicated as front, rear, right, and left from the operator's perspective; however, the configuration is not limited by these directions.

[0022] As shown in Figure 1, the combine harvester 1 has a running gear 4 on the lower side of the chassis 2, with a pair of left and right crawler tracks 3 that travel on the soil surface. On the left and right sides of the chassis 2 are a threshing device 6 that threshes and sorts the stalks of grain that are carried and supplied by the feed chain 5, a grain tank 7 that temporarily stores the grain, and a grain auger 8 that discharges the grain stored in the grain tank 7 to the outside of the machine. A straw disposal device 9 is mounted on the rear end of the threshing device 6. The grain auger 8 raises and lowers when the auger lifting cylinder is operated to discharge the grain.

[0023] A harvesting device 15 is mounted on the front end of the chassis 2 so as to be able to move up and down relative to the soil surface by a harvesting lifting cylinder, and is configured in front of the threshing device 6. The harvesting device 15 has a weeding body 11 that separates unharvested grain stalks from the front end, a lifting unit 12 that raises the separated grain stalks, a cutting blade unit 13 that cuts the raised grain stalks, and a supply adjustment and conveying unit that scoops up the harvested grain stalks and adjusts the handling depth during conveyance before handing them over to the feed chain 5.

[0024] An operating device for controlling the operation of the combine harvester 1 and an operating seat 17 for the operator are provided at the upper rear of the harvesting device 15. An engine E is mounted below the operating seat 17, and the grain tank 7 is positioned at the rear. A cabin 18 is provided to cover the operating device and the operating seat 17. These components, including the running gear 4, threshing device 6, harvesting device 15, operating device, engine E, cabin 18, etc., are mounted on the chassis 2 of the combine harvester.

[0025] The operating device includes a main gear lever that operates a gear actuator that switches between forward and reverse movement and stopping, and switches the main gear by forward and backward operation by the operator seated in the operator's seat 17; a steering lever that operates left and right travel actuators that operate left and right side clutches and left and right side brakes of the left and right travel crawlers 3,3 by tilting to the left and right, thereby enabling left and right steering when moving straight and turning in various turning modes; a steering lever that operates the harvesting lifting cylinder to raise and lower the harvesting device 15 by forward and backward operation; a harvesting / threshing lever that operates the harvesting clutch actuator to turn the drive of the harvesting device 15 and the threshing device 6 on and off; an auger operation lever that moves the grain discharge auger 8 vertically by operating the auger lifting cylinder and horizontally by operating the left and right turning actuators; and an auger drive switching lever that operates the auger drive electromagnetic clutch to turn the drive of the grain discharge auger 8 on and off, thereby discharging grain from the grain tank 7 to the outside of the machine.

[0026] A support frame 19 extending upward is provided on the upper right (or upper left) side of the harvesting device 15. Work lights 20, consisting of LED lights that illuminate the front and right (or front and left and right) sides of the harvesting device 15, are mounted on the support frame 19 to improve nighttime visibility. Side mirrors 21 are also provided on the support frame 19.

[0027] As shown in Figures 2 to 5, the fuel tank 25 is mounted on the chassis 2 at the rear of the aircraft, extending in the left-right direction.

[0028] Specifically, the rear ends of the left and right frames 2L and 2R of the chassis 2 are connected by the rear frame 2B, and the fuel tank 25 is placed from above in the space between the left and right frames 2L and 2R and the rear frame 2B, and is fixed to the chassis 2 with fixing bolts using two fixing members 26 made of steel strips.

[0029] Therefore, the fuel tank 25 can be easily attached to and detached from the rear of the aircraft body to the rear end of the chassis 2, improving the efficiency of maintenance work such as inspection and servicing.

[0030] The fixing members 26 are attached to the fuel tank 25 at two locations: inside the left and right side plates 6L and 6R of the threshing device 6, and on the right outer side of the right side plate 6R. The cross-sectional shape of the parts of the fuel tank 25 to which the fixing members 26 are attached is the same at both locations.

[0031] Therefore, the number of parts can be reduced and assembly can be improved.

[0032] Furthermore, during the manufacture of the combine harvester 1, the fuel tank 25 is first attached and fixed to the chassis 2, and then the threshing device 6 is installed, making assembly easy and improving production efficiency.

[0033] The fuel tank 25 extends from a position below the rear of the threshing device 6, with its right side 25a extending to the right and outward beyond the right side plate 6R of the threshing device 6, and reaching a position below the grain tank 7.

[0034] Furthermore, the right portion 25a protrudes rearward from the rear end of the right side plate 6R and rearward from the rear frame 2B of the chassis 2, is located in front of the rear end of the auger lower member 8b (which forms a horizontal spiral cylinder that discharges grain from the bottom of the grain tank 7 and transports the grain to the vertical spiral cylinder 8a) that rotatably supports the vertical spiral cylinder 8a of the grain discharge auger 8, and is positioned lower than the oscillating shaft 36a of the oscillating sorting rack 36 of the threshing device 6.

[0035] Furthermore, the fuel tank 25 has a bottom surface that bulges downward, forming a downward bulge portion 25b, which is fitted into the space formed by the left and right frames 2L, 2R and the rear frame 2B of the chassis 2.

[0036] Therefore, the right portion 25a of the fuel tank 25 extends to the right and outward beyond the right side plate 6R of the threshing device 6, reaching the lower position of the grain tank 7, and protrudes rearward from the rear end of the right side plate 6R and rearward from the rear frame 2B of the chassis 2, and is further provided with a downward bulge portion 25b, thus making it possible to obtain a large-capacity tank.

[0037] Furthermore, since the right portion 25a of the fuel tank 25, which protrudes from the rear of the machine, is located in front of the rear end of the auger lower member 8b of the grain-discharging auger 8, the front-to-rear length of the machine can be shortened, resulting in a more compact machine size. In addition, even if the rear of the machine comes into contact with a wall or other object, the auger lower member 8b functions as an interference protection member, preventing damage to the fuel tank 25 and improving safety.

[0038] Furthermore, a lidded fuel inlet 28 is provided on the upper surface of the right portion 25a, which extends to the right and outward beyond the right side plate 6R and protrudes toward the rear. A fuel gauge 29 is provided to the right and outward beyond the right side plate 6R of the threshing device 6 and behind the oscillating shaft 36a of the oscillating sorting rack 36.

[0039] Furthermore, the oil inlet 28 is positioned between the threshing device 6 and the vertical spiral cylinder 8a and auger lower member 8b of the grain auger 8 when viewed from the rear, and is located lower than the oscillating shaft 36a of the oscillating sorting rack 36.

[0040] Therefore, a fuel filler port 28 is provided on the upper surface of the right portion 25a that protrudes to the rear of the aircraft, and since the fuel filler port 28 is located lower than the oscillating shaft 36a of the oscillating sorting rack 36, fuel can be easily supplied from the rear of the aircraft, resulting in good work efficiency.

[0041] Furthermore, since the fuel gauge 29 is located to the right and outward of the right-side plate 6R of the threshing device 6 and behind the oscillating shaft 36a of the oscillating sorting rack 36, the wiring harness for the fuel gauge 29 can be simplified, and maintainability can be improved.

[0042] Furthermore, the fuel tank 25 is positioned further rearward than the second conveying right outer end member 30 of the threshing device 6 (the part located on the outside of the right side plate 6R of the second spiral).

[0043] Therefore, since the fuel tank 25 is positioned further rearward than the second conveying right outer end member 30 of the threshing device 6, the assembly work of mounting the threshing device 6 after attaching and fixing the fuel tank 25 to the chassis 2 is easy and production efficiency is high.

[0044] The fuel intake nozzle 31, which draws fuel from the fuel tank 25 and sends it to the engine E, is located in front of the downward bulge 25b of the fuel tank 25 and is positioned so as not to protrude from the front end surface of the fuel tank 25 in a plan view.

[0045] Therefore, since the intake nozzle 31 is provided in the lower bulge portion 25b of the fuel tank 25, air can be prevented from entering the fuel.

[0046] Furthermore, since the suction nozzle 31 is positioned so as not to protrude from the front end surface of the fuel tank 25 in a plan view, it is possible to avoid the suction nozzle 31 interfering with and being damaged by surrounding components when the fuel tank 25 is mounted on the chassis 2.

[0047] Furthermore, the fuel return nozzle 32, which returns the fuel returned from engine E into the fuel tank 25, is positioned at the front of the fuel tank 25 and above the top surface of the chassis 2.

[0048] Therefore, since the return nozzle 32 is located in front of the fuel tank 25 and above the top surface of the chassis 2, the return fuel hose 33 can be shortened, and the hot fuel returning from the engine E returns to a position above and away from the intake position where the intake nozzle 31 is located, thereby preventing the intake nozzle 31 from sucking in the hot fuel.
