BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain storage device for temporarily storing grains, which have been threshed in a threshing unit, in an airframe.

[0002]

2. Description of the Related Art In a combine harvester, grains harvested in a threshing unit during a harvesting operation are sorted in a sorting unit, and then lifted and transported to a tank for storing grains in a frying cylinder and stored in the tank. When the tank is full, the harvesting operation is suspended,
The grains in the tank are discharged by a bag packing method (bag packing method) or directly discharged to a truck or the like via a discharge tube (naked paddy transfer method). Therefore, in order to reduce the number of interruptions of the work and increase the efficiency of the mowing, it is desirable to set the tank capacity as large as possible from the beginning. Therefore, conventionally, there is provided a sub-tank in which one upper side of the grain storage tank is extended above the threshing unit and is connected to the main tank side, and the sub-tank is configured to be rotatable in a vertical direction. Known (JP-A-58-237)
No. 21).

[0003]

However, the above-mentioned conventional structure has a structure in which the main tank and the sub-tank are rotated about a fulcrum shaft provided at the joint on the bottom plate side, so that the grain discharge is performed. At this time, when the sub-tank is turned upward to move the grains on the sub-tank side to the main tank side, the rotation start end side of the sub-tank enters the main tank together with the grains, so that the entire tank is The effective volume is reduced, and the sub-tank directly receives the paddy resistance in the main tank, which causes problems such as hindering rotation of the sub-tank. Therefore, the discharge of the grains on the sub tank side has to be performed after the discharge of the grains on the main tank side, and the workability is poor.

SUMMARY OF THE INVENTION A grain storage device for a combine according to the present invention has been made in response to the above-mentioned demands, and has a central tank at one upper side of a main tank.
In a combine having a sub-tank extending above the threshing unit, the upper part of the sub-tank at the starting end side is a central tank .
And pivotally connect to the upper end
At the bottom, it descends toward the main tank side facing the central tank
The closing plate obliquely arranged, and summarized in that sub tank of the entire grain discharging position deterministic link is pivoted upwardly displaced volume is configured to increase.

[0005]

[Function] During harvesting, when the tank is full of kernels, the harvesting is temporarily stopped, the truck is moved to a standby place of a truck or the like, and the kernels are discharged, but the kernels in the tank are at the bottom of the main tank. Is fed to the rear part of the aircraft by the horizontal feed spiral, and then discharged to the carrier of the carrier by the spiral discharge tube. In this grain discharging operation, when the hydraulic cylinder is expanded and contracted, the sub-tank turns upward around the fulcrum shaft provided at the upper part of the tank, but the sub-tank does not sink into the central tank. The grains in the sub-tank do not receive the resistance in the central tank and the main tank. In addition, the lower part of the fulcrum shaft expands in a fan shape to increase the effective volume of the entire tank, but the bottom side of the expanded part is covered by a blocking plate, and both front and rear sides are covered by a cover plate integrated with the central tank. The grains in the sub-tank do not leak out of the tank and flow smoothly down to the main tank via the central tank.

The central tank 9 is open on both left and right sides, and has a bottom plate 9a inclined downward toward the main tank 10 and forward, and a cover plate 9b extending toward the front and rear plates 11a and 11b of the sub tank 11. It is fixed via a bracket 7b to the vicinity of the upper end outlet 7a of the fryer 7 which penetrates the rear side of the central tank bottom plate 9a. The central tank 9 has a substantially trapezoidal shape with a narrow front portion in a plan view.
In order to escape the discharge cylinder 8 which is stored on the upper surface of the machine in the front-rear direction at the time of storage, the upper surface is formed in a stepped shape on the side closer to the main tank 10 and lower on the side closer to the sub tank 11. A locking portion 12 of a stopper R for locking the main tank 10 at the set position is provided on the upper portion, and the overflow port 9 is provided on the lower portion.
c is provided with a cover 9d. With this configuration, a concave portion a that is inclined in plan view is formed between the upper surface of the central tank 9 and the sub tank 11 so that the discharge tube 8 can be substantially completely immersed when the discharge tube 8 is stored. In addition, this recess a
Since the overflow port 9c is located on the bottom surface, the grains overflowing from the central tank 9 are retained in the recesses a without spilling out of the machine and can be easily collected. Reference numeral 13 denotes a discharge tube seat fixed to the front surface of the central tank 9. On the other hand, between the main tank 10 and the threshing unit 2, there is provided a frame 14 integrally connecting the hulling cylinder 7, the body frame 3 and the threshing unit 2.
