Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain supply device for supplying grains of a grain dryer to a grain storage room.

[0002]

2. Description of the Related Art Conventionally, for example, when a grain storage chamber of a grain dryer has a rectangular shape that is long in the front-rear direction, an upper transfer gutter is provided in the center in the left-right direction above the storage chamber in the front-rear direction. ,
The grains supplied to the starting end of the upper transfer gutter in the transfer direction are:
Transferred in this upper transfer gutter, from the center in the front-rear direction,
Below the upper transfer gutter, the mixture is supplied onto a rotatable diffusion plate, and the grains are diffused and supplied into the storage chamber by the rotation of the diffusion plate.

[0003]

The grain is supplied onto the diffusion board from the center in the front-rear direction of the upper transfer gutter, and is diffused and supplied into the storage chamber by the diffusion board, so that the grain supplied by the diffusion is supplied. Depending on the state of pity, blue rice, and straw debris, the distribution of grains into the storage room changes, causing poor distribution, and the grains are distributed by rotational diffusion. As a result, the sound generated when the grain hits the inner surface of the machine wall forming the storage chamber is high, and the drying operation is performed much at night, and thus the generated sound becomes noise. However, these problems are to be solved by the present invention.

[0004]

SUMMARY OF THE INVENTION To this end, the present invention relates to a grain dryer for supplying grains to a grain storage chamber 9 for storing grains from an upper transfer gutter 7 for receiving and transferring the grains.

When the predetermined time is over, the opening / closing plate 32 moves to close the supply port 29 on the start end side and open the grain supply port 30 in the center. From the supply port 30 that has been opened and the storage chamber 9 is open.
The grain is dropped and supplied to the central portion of the inside for a predetermined time, and when the predetermined time ends, the opening / closing plate 32 moves to close the supply ports 29 and 30 at both the start end portion and the central portion. The grain is dropped and supplied from the grain supply port 31 on the end side to the rear part in the storage chamber 9 for a predetermined time, and when the predetermined time ends, the supply port 29 on the start end side again. The opening / closing plate 32 is moved to be opened, and the grains are dropped and supplied from the opened supply port 29 to the front part in the storage chamber 9 for a predetermined time. It is repeated,
The grains are evenly supplied into the storage chamber 9.
