A shutter 37 for opening and closing the outlet 31 formed in the joint 27 is provided, and the shutter 37 is connected to an operating lever 38.

In addition, guide tubes 39 and 40 are connected to each outlet 31 and 32, and synthetic rubber tubes 41 and 42 are telescopically secured to the guide tubes 39 and 40 with bolts 43 and 44, respectively.

Furthermore, the receiving rod 35 is connected 46 to the lower end of a support shaft 45 so as to be able to swing freely in the middle so that the tip thereof can move up and down. A pin 48 is engaged with one of the height adjustment holes 47 formed in the . . . , and the support shaft 45 is removably fixed to the metal fitting 36, and the empty grain storage bag 34 is suspended from the receiving rod 35. Attach a spring 49.49 to the receiving rod 35 so that it is approximately horizontal in this state.
will be assisted.

Note that the horizontal discharge conveyor 23 has a machine frame stand 50 in the middle.
It is placed on the aircraft and stored horizontally in the diagonal direction above the aircraft.

The present invention is constructed as described above, and the culm is continuously harvested and threshed, and the grains taken out from the threshing section 6 are stored in the storage tank 1.
8, the reaping and threshing operations are interrupted as shown in FIG. 4, the combine harvester is brought close to the farm road, and the tip of the lateral discharge conveyor 23 is moved up and down and horizontally rotated to extend onto the farm road.

Then, the receiving rod 35 is attached to the fixture 36 at an appropriate height via the support shaft 45, and the receiving rod 35 is made to support an appropriate number of grain storage bags 34.

At this time, the support shaft 45 is adjusted up and down so that the receiving rod 35 becomes approximately horizontal due to the springs 49 and 49, and the bottom of the bag 34 is in contact with the ground surface, etc., and the cylinder 41
．． The tubes 41 and 42 are adjusted to expand and contract according to the inclination of the conveyor 23, etc., so that the tip of the tube 42 can be slightly inserted into the bag 34.

Then, when the tube 42 at the tip of the conveyor 23 is placed in the grain storage bag 34 and each conveyor 2L22.degree. 23 is driven,
When the joint 270 outlet 31 is closed with the shutter 37 as shown in FIG. The grains fall into this lower bag 34.

When a suitable amount of grain is accumulated in the bag 34, the receiving rod 35 descends in one direction due to the weight, loosening the bag 34.
The inside is filled with grains.

As mentioned above, when the grain storage bag 34 below the dispensing port 32 is filled with grains, the shutter 37 is opened via the operation lever 39 to open the dispensing port 31. The grains sent out by the auger 25 fall into the grain storage bag 34.

At this time, the grains are not sent to the outlet 32, and while the lower bag 34 is removed and the empty bag 34 is attached to the tube 42, the grains are not sent to the bag 34 below the outlet 31. When it is filled, the shutter 37 is closed via the lever 39, and the grains are dropped downward from the outlet 32.The shutter 37 is opened and closed in this way, and the grains are alternately dropped from each outlet 31 and 32. The storage bags 34 are continuously filled with grains by dropping the grains.

The receiving rod 35 can be foldably assembled into the horizontal discharge auger 23, and a plurality of discharge ports 31, 32 can be easily formed in the joint 27 or the discharge tube 30.

As shown in the embodiments above, the present invention includes a storage tank 18 for storing the grains taken out from the threshing section 6, and a discharge conveyor 23 for delivering the grains in the tank 18, and for changing the direction of the discharge conveyor 23. In the structure where the connecting shaft 2
