[Problems to be solved by the device]

 Although a grain tank with such a structure has been disclosed as a grain tank for mounting a combine, a combine with this grain tank has a structure in which the grain tank of the machine is empty when the grain tank is empty or nearly empty. The center of gravity is biased toward the front side, and this tendency is particularly noticeable in the case where the engine is installed behind or below the cockpit, and in the case where a straw disposer such as a binding machine is installed. On the contrary, the position of the center of gravity is biased to the rear side, and in any case, the front-rear balance of the aircraft becomes poor, and the aircraft becomes unstable especially in wetlands, resulting in poor traveling performance. In view of the above drawbacks of the conventional combine, the present invention intends to improve the front-rear balance of the airframe to stabilize the airframe and improve the running performance in wetlands in order to eliminate the drawbacks. To do.

[0004]

[Means for Solving the Problems] In order to improve the front-rear balance of the airframe and to stabilize it and improve the running performance in the wetland as described in the preceding paragraph, the present invention provides the grain tank with an appropriate height. A partition plate divides the grain into multiple pieces in the front-rear direction of the machine, and at the grain discharge port at the top of the fried cylinder, the grain input can be selectively switched to the desired one of the above-mentioned multiple pieces. A flexible valve body was installed to fill the compartment farthest from the center of gravity of the aircraft and fill it, and then the upper edge of the partition plate was overflowed to store it in the adjacent compartment. Of.

[0005]

[Action]

 With this configuration, if the combine is to install the engine behind or under the cockpit, for example, and the center of gravity of the airframe is biased toward the front, lift it from the threshing section. When storing grains in the grain tank via the grain machine, switch the valve provided at the grain discharge port at the upper end of the fried cylinder to store the grains in the compartment on the rear side of the machine farthest from the center of gravity. It is thrown in. Then, as the grain accumulated in this section, the center of gravity, which was biased toward the front side, moved to the rear side, and the front-rear balance of the aircraft was corrected, and while the aircraft was stable, the area was filled with grains. Then, overflowing over the upper edge of the partition plate, it overflows and is sequentially stored in the wa compartment, which is close to the adjacent center of gravity. Also, when the machine is equipped with a straw disposer such as a binding machine and the center of gravity of the machine body is biased to the rear side, the valve body is switched and the section on the front side of the machine body farthest from the center of gravity position is switched. As the grains are put inside, the center of gravity, which was biased to the rear side rapidly as the grains accumulated, moved to the front side, and the front-rear balance of the aircraft was corrected while the grains were filled in the section. Then, over the upper edge of the partition plate and near the adjacent center of gravity, it overflows into the compartment and is sequentially stored.

【Example】

 A grain tank for mounting a combine according to the present invention will be described below with reference to an embodiment diagram. The combine is equipped with a thresher (A) on the left side of a machine stand (7) mounted on a traveling device (6). The engine part (8) containing the engine for driving and the grain tank (2) for storing the grains selected by the threshing part (A) and wind-selected on the right side are mounted on the front and back. However, the cockpit (9) is provided in front of the engine section (8), and the mowing section (B) is arranged in front of the threshing section (A). The grain is selected, the grains are lifted up through the grain barrel (1) and temporarily stored in the grain tank (2), and the straw after threshing is dropped to the rear of the machine, and the grain tank (2 The grain stored in () is lifted up by the fried cylinder (10) standing upright on the rear side of the grain tank (2). Deo - is adapted to be removed to a suitable place inherited by gas (11).

Then, the grain tank (2) is divided into a plurality of things (2a) (2b) in the front-rear direction of the machine body by a partition plate (3) having an appropriate height, and is separated from the threshing portion (A). The grain-lifting cylinder (1), which is used to lift and store the grains in the grain tank (2), is provided along the outer wall of the grain tank (2) where the partition plate (3) is erected, and the upper end is provided. The grain outlet (1a) of the partition plate (3) is opened above the upper edge (3a) of the partition plate (3) across the front and rear sections (2a) and (2b), and the grain outlet (1a) is opened. Vertical fulcrum shafts (12) and (13) are provided on both sides of the part, and the valve discs (4) and (5) are fixed to the fulcrum shafts (12) and (13) to secure the valve discs (4) and (5). Change the orientation of the grains thrown in from the grain outlet (1a) to the front side section (2a) or the rear side section (2b). I am doing it.

In addition, (14) is a screw conveyor installed in the fried grain cylinder (1), and (15) is a pop-out plate integrally attached to the upper end of the screw conveyor (14), (16) is a lever for changing the posture of the valve bodies (4), (5).

Therefore, the grain from the threshing section (A) is lifted up by the grain frying tube (1) and thrown into the grain tank (2) from the grain outlet (1a) at the upper end and temporarily stored. However, in the combine shown in this embodiment, the engine part (8) having the built-in engine is installed on the rear side of the steering seat (9). Since it is biased toward the front side, the levers (16) are operated to change the postures of the valve bodies (4) and (5) as shown in the cross section in FIG. The grain jumped out from the outlet (1a) is directed into the compartment (2b) on the rear side of the fuselage farthest from the center of gravity (G) as indicated by the arrow (a). Then, the center of gravity (G), which was rapidly biased to the front side as the grains accumulated in this section (2b), moved to the rear side as shown by the arrow (b) in "Fig. The balance is corrected and the aircraft becomes stable. When the grain is filled in the compartment (2b), it crosses the upper edge (3a) of the partition plate (3) and adjoins the front compartment (2a) as shown in (c). ) Overflows and is sequentially stored.

Further, although not shown, when the straw processing machine such as a binding machine is attached and the center of gravity (G) of the machine body is biased to the rear side, the valve body (4) is (5) is switched as shown by the phantom line in "Fig. 2" so that the grain is put into the front section (2a). As the grain accumulates, the center of gravity is biased to the rear side rapidly. When the position (G) moves to the front side and the front-back balance of the aircraft is corrected and the grain is filled in the section (2a), it goes beyond the upper edge (3a) of the partition plate (3) to the rear side. It is overflowed in the section (2b) and is sequentially stored.

Further, although detailed description has been omitted in the description of the embodiment of the present invention, when working in a combine wetland, the front and rear tilt of the aircraft due to the sinking of the aircraft is detected, and When the valve bodies (4) and (5) are automatically switched based on the detection, and the sections (2a) and (2b) before and after the switching are selected and the grain is put in, the valve bodies (4) and (5) are manually operated. By eliminating switching by operation, the aircraft is stable and running performance is good.
