Description

[Detailed Description of the Invention] This invention relates to a grain storage device configured to be able to store and discharge grains discharged and supplied from a grain lifting device.

Conventionally, this type of grain storage device consists of a hopper, and the hopper is usually provided with an inspection window and an opening/closing lid for opening and closing the hopper. However, if the lid is opened carelessly, the grains that are being released and supplied will scatter outside through the inspection window, resulting in grain loss.

The purpose of this invention is to eliminate the above-mentioned drawbacks by specially devising the opening/closing lid.

For this reason, the following technical measures were taken.

That is, in the hopper 5, which has a grain storage chamber 3 communicating with the discharge port 2 of the grain lifting device 1 in the upper part and a discharge port 4 for discharging the stored grains in the lower part, The wall surface of the hopper 5 facing the grain ejection direction A from the discharge port 2 is opened as an inspection window 6, and the opening/closing lid 7 for opening and closing the inspection window 6 is opened and closed on the upper side 7a around its lower shaft 8. The structure of the grain storage device is provided so that the grain storage device can be moved.

In the illustrated example, 9 is a combine harvester, which includes a threshing machine 11 mounted on a chassis having a traveling device 10,
This is a conventionally known device consisting of a reaping and conveying device 12 provided at the front part.

The grain hoisting device 1 consists of a hoisting cylinder 14 having a hoisting spiral 13 therein, the lower part communicates with the threshing machine 11, and the upper part has a discharge port 2 provided in a substantially horizontal manner. This discharge port 2 is provided with a springing blade 15 provided at the upper end of the lifting spiral 13.

The hoppers 5, 5 are supported side by side in communication with each other via a partition wall 5a, and have a storage chamber 3 formed in the upper part and a discharge port 4 having a shutter 16 in the lower part. ing.

The discharge port 2 of the grain frying device 1 is located at the partition wall 5a of the hoppers 5, 5, and is provided so as to look into the storage chamber 3.

The inspection window 6 extends between the left and right hoppers 5, and is formed by opening the upper wall surface of the hoppers 5, which face the discharge port 2.

The opening/closing lid 7 opens and closes the inspection window 6, and has a lower part 7b rotatably supported by a shaft 8 on the hopper wall surface, and an upper part 7a which can be rotated to open and close. 17 is a set bolt for fixing and releasing the upper part of the opening/closing lid 7. 18 is a grain bag.

In the configuration of the above example, when the combine harvester 9 is operated with the discharge ports 4 of the hoppers 5, 5 closed by the shutter 16, the grains threshed by the threshing machine 11 are lifted by the grain lifting spiral 13. After being lifted up, the springing blade 15 passes the discharge port 2 to the storage chamber 3.
It is stored while being bounced inward in the direction of arrow A. At this time, the grains from the discharge port 2 are diffused and supplied into the left and right storage chambers 3, 3 almost simultaneously.

During this grain storage work, for example, if the opening/closing lid 7 is accidentally opened to inspect the grain inside the hopper 5 or the inspection window 6 is opened by mistake, the opening state of the opening/closing lid 7 may change. As shown by the imaginary line in Fig. 3, the upper part 7a side rotates around the axis 8 of the lower part 7b and becomes an upright state, so that the grains that are thrown away from the discharge port 2 in the direction of arrow A are caught in this upright opening and closing state. This prevents the particles from hitting the lid 7, falling back into the storage chamber 3, and scattering outside through the inspection window 6.

When the storage chambers 3, 3 are filled with grains, each shutter 16 is opened to open the discharge port 4, and the stored grains are stored in the grain bag 18.

In this invention, since the structure is as described above, when grains are being discharged and supplied to the storage chamber 3 of the hopper 5 through the discharge port 2 of the grain frying device 1, the opening/closing cover 7 may be opened carelessly and the inspection window 6 may be opened. Even if it is opened, the opening/closing lid 7 remains in an upright position, so the storage chamber 3 can be accessed through the opened inspection window 6.
The grains released from the discharge port 2 that are about to scatter outside can be caught and dropped into the storage chamber 3 again, and this has the effect of preventing the grains from scattering outside the storage chamber.
