[Effect] Next, the effect will be described. When the machine moves forward, the grain culms in the field are harvested by the reaping section, the harvested grain culms are supplied to a threshing device for threshing, and the threshed grains are taken out by the No. 1 conveyor. At the end of the No. 1 conveyor there is a feeding grain cylinder 13.
Since the lower part of the grain tank 6 is connected, the grain taken out by the No. 15 conveyor is fried by the supply grain lifting cylinder 13 and temporarily stored in the grain tank 6. When a certain amount of grain is stored in the grain tank 6, the machine is moved to a light rack waiting near the field, and the grain ejection device 17 is activated to remove the ejection tube 16 from the grain tank 6. The grains flowing through the lower fixed cylinder part 18 are fried by the discharge grain lifting cylinder 19 and enter the discharge auger 20. The grains are discharged by the discharge auger 20 into a light 1-rack tank and then transferred to the grain tank 6. Carry out grain discharge work from. [0019] When the reaping and threshing work and the discharge work are completed, the operation lever 45 is operated to disengage the locking hook 41 and the engagement shaft 42, and the discharge tube 16 of the grain tank 6 is removed. Disconnect the lower fixed cylinder part 18 of the grain frying discharge device 17, remove the casing 14 of the feeding grain cylinder 13 from the inner side wall 7 of the grain tank 6, and connect the grain tank 6 to the upper shaft 29 at the upper part and the lower part at the lower part. When the grain tank 6 is opened outward around the shaft 21, the lower fixed cylinder part 18 of the grain fried grain discharging device 17 and the casing 14 of the supply grain raising cylinder 13 remain on the aircraft body side, and the grain tank 6 is opened outward from the upper shaft 29. It horizontally rotates outwardly around the lower shaft 21. Therefore, a wide space is formed around the side wall 8 of the threshing device 4, and maintenance such as inspection and cleaning of the transmission device etc. can be easily performed. [00201 In this case, the rear lower part of the grain tank 6 is attached to the lower shaft 21 which is fixed to the lower fixed cylinder 18 which is fixed to the fuselage frame 1 by a stay 18', and the rear upper part of the grain tank 6 is attached to the lower part of the lower part of the grain tank 6. It is attached to an upper shaft 29 provided on the same axis as the shaft 21, and the upper shaft 29 connects the upper frame 24 of the rear support frame 23 fixed to the body frame 1 side and the straw disposal device 5 side, and the threshing device 4. Since it is pivoted to the support member 28 which is supported and fixed by both the rear frame 32 of the tank rotation support frame 31 fixed to the supply grain cylinder 13 side, the grain tank 6 is firmly supported.
rotates outward smoothly. [00211 Furthermore, the engagement shaft 42 of the fixing device 40 that fixes the grain tank 6 in the storage position is connected to the side wall 8 of the threshing device 4.
a locking hook 41 that engages with the engagement shaft 42;
is provided on the inner side wall 7 of the grain tank 6, so
When rotating the grain tank 6 to open outward, the locking hook 4
1 does not interfere with the operation frame 11, the front wall 10 of the grain tank 6 can be brought closer to the operation frame 11 than in the conventional case, and the volume inside the grain tank 6 can be increased. [0022] Furthermore, since the paddy receiver 46 is provided below the connection part between the discharge pipe 16 of the grain tank 6 and the lower fixed cylinder part 18 of the fried grain discharge device 17, the discharge pipe 1
When the grains 6 are separated from the lower fixed cylinder part 18, the grains spilled from the openings of the discharge pipe 16 and the lower fixed cylinder part 18 fall onto the paddy receiver 46, so that they can be collected reliably and easily. [00231 In the embodiment shown in FIGS. 10 and 11,
The auger rotation motor 49 that rotates the discharge auger 20 is located between and surrounded by the discharge grain cylinder 19 and the rear wall 15 of the grain tank 6, so it prevents interference with ridges and the like and prevents damage. This situation can be avoided. In addition, the gear 50 on the rotating shaft of the auger rotation motor 49 and the gear 51 on the lower outer circumferential surface of the discharge grain cylinder 19 are accurately aligned, meshing smoothly, and the installation of the auger rotation motor 49 is easy. Strength is also improved. [0024] Additionally, in the embodiments of FIGS. 12 and 13,
Since the auger turning motor 49 is surrounded by the mounting stay 55 and the mounting stay 56 of the flasher 54 of the direction indicator 53, interference with ridges etc. is prevented, and
This eliminates the need to separately provide a guard body for the auger rotation motor 49. [0025]

[Effect] The present invention provides a fuselage frame 1 having a traveling device 2.
A threshing device 4 is provided at an upper position on one left and right side of the machine frame 1, and a grain tank 6 is provided at an upper position on the other left and right side of the body frame 1, and a grain tank 6 is provided at a rear position of the grain tank 6 for hoisting the grain in the grain tank. A grain lifting cylinder 19 is provided between the threshing device 4 and the grain tank 6, and a supplying grain lifting cylinder 13 extending from the threshing device 4 to the grain tank 6 is provided, and the lower side of the discharge grain lifting cylinder 19 is connected to the machine frame. 1, the lower sides of the supply grain lifting cylinder 13 are each fixed to the threshing device 4, and the upper sides of the discharge grain lifting cylinder 19 and the supply grain lifting cylinder 13 are fixed to the body frame 1 side. 23.
31 etc., and the grain tank 6 is horizontally rotatably fixed to the discharge grain cylinder 19 by a lower shaft 21 and an upper shaft 29, and is detachable from the supply grain cylinder 13. The grain tank 6 is fixed to the discharge grain cylinder 19 by a lower shaft 21 and an upper shaft 29 so as to be horizontally rotatable. This allows the shaft to be securely fixed. Further, since the lower side of the discharge grain barrel 19 is fixed to the machine frame 1 and the upper side is fixed to the support frame 23 fixed to the body frame 1 side, the grain tank 6 has a robust structure. 19, and is more robust. Further, since the supply grain barrel 13 that fixes the grain tank 6 at the use position is also fixed by the support frame 31, there is an effect that the grain tank 6 does not wobble at the use position. Incidentally, since a part of the support frame 31 is fixed to the discharge grain cylinder 19, there is an effect that the support frame 31 is mutually robust.
