Description

[Detailed description of the invention] This invention supplies grain after threshing to a plurality of bagging hopper chambers arranged side by side in the interior and exterior directions of the machine, and stores the grains in storage bags placed at the bottom of each hopper chamber. The present invention relates to a grain collecting device in a combine harvester.

Since this type of grain collecting device has multiple hopper chambers, the amount of grain that can be accommodated is reduced and the work can be carried out efficiently. However, on the other hand, when working in wet fields, etc. There was a problem in that the large amount of grain stored in the hopper room caused the machine to tilt, making it difficult to run stably.

The present invention was made keeping in mind the above actual situation,
A plurality of bagging hopper chambers are arranged side by side in the interior and exterior directions of the machine, and a grain guide plate is provided on the cover that covers the top of the hopper, the upper end of which is pivotally connected around the front and back axis. When the guide plate is rotated downward, the grains are supplied only to the hopper chamber inside the machine, and when the guide plate is rotated upward and changed to a position along the inner surface of the cover, all the grains are supplied. It is characterized in that it is configured to feed into a hopper chamber.

In other words, the rotatable guide plate provided on the cover that covers part of the hopper allows the grains that are scattered and supplied from above the hopper chamber after threshing to be supplied only to the hopper chamber on the inside of the machine. Since it can freely switch between the state and the state where it can supply to all hopper rooms, it is possible to perform efficient work using all hoppers when there is no risk of the machine being tilted, such as when working in dry fields. When the machine is likely to be in a tilted position, such as when working in wet fields, it is possible to prevent the machine from tilting due to grains as much as possible by using only the hopper room on the inside of the machine. Regardless of changes in working conditions, such as in wet fields, the work can always be done well.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

The exemplified combine harvester moves with a crawler traveling device 1.1, uses a front lifting device 2 to lift the planted stem culm into an upright position, and uses a reaping device 3 to cut off the base end of the plant and harvest it. The stem culm is configured to be transported to a rear threshing device 5 by a vertical transport mechanism 4.

The threshing device 5 is configured to handle and thresh the tips of the stalks while pinching and conveying the stem culms with a feed chain 6 wound around the sides, and threshes the grains after the threshing process. The grains are supplied to a grain collecting device disposed on the side of the threshing device 5 via a grain conveying device having a helical screw 8 installed inside a conveying cylinder 7.

The grain collecting device will be described in detail below.

That is, four hopper chambers 9a, 9b, 9c.

A hopper main body 9, which is formed by partitioning the hopper 9d in the lateral and longitudinal directions of the machine, is disposed on the lateral and lateral sides of the threshing device 5, and a shutter is provided in the lower part of each hopper chamber 9a. Grain discharge tubes 10a, 10b, 10 with
c, 10a are attached, and grain storage bags 11, whose upper ends are suspended and supported, are provided corresponding to each discharge cylinder 10a, respectively.

Therefore, the grains lifted and conveyed along the conveyance tube 7 are transported by the rotary blades provided at the upper part of the helical screw 8.
2, they are scattered and supplied to the upper part of each hopper chamber 9a, and are sequentially collected into the storage bags 11, and when the collection into the bags 11 is completed, they are then sequentially collected into the hopper 9. Ru.

Incidentally, when the inside of the container bag 11 and the hopper 9 are full of grains, a new storage bag is replaced and grain collection is continued.

In addition, in order to switch between supplying grains to all hopper chambers 9a and supplying grains only to hopper chambers 9b and 9d on the inside of the machine, depending on the working conditions such as dry field work and wet field work, the following is done. It is equipped with the grain guiding mechanism described in .

That is, a cover 13 covering the upper part of the hopper main body 9
is equipped with a grain guide plate 14 whose upper end is pivotably connected around the front and rear axis.

Then, rotate this guide plate 14 upward to remove the cover 1.
3, grains are supplied to all the hopper chambers 9a..., and the guide plate 14 is rotated downward to feed the grains to the hopper chambers 10b, 10 on the inside of the machine.
As the attitude is changed to separate the hopper chambers 9a and 9c on the outside of the machine, grains are transferred to the hopper chamber 10 on the inside of the machine.
b.

10d.

The guide plate 14 is connected via a release wire 16 to a swinging lever 15 provided on the outside of the hopper main body 9, and by swinging the lever 15, the posture is changed as described above. By engaging and holding the lever 15 in an engaging groove 17a or 17b formed in the guide frame 17, the lever 15 is configured to be held in each posture.

Further, in the embodiment, the case where the hopper 9 is arranged on the lateral side of the threshing device 5 is illustrated, but the hopper 9 may be arranged and connected in the rear part of the threshing device 5 in the inner and outer directions.
