Description

[Detailed description of the invention] Industrial application field The present invention is a grain dryer in which an elevator is attached to one side of the dryer body, and grain is thrown into a grain storage tank from the elevator. The present invention relates to a grain distribution device for evenly storing grains in a tank.

Prior Art A grain dryer in which an elevator is attached to one side of a main body of a dryer having a grain storage tank at the top and grain is thrown into the grain storage tank from an upper throwing port of the elevator is disclosed in, for example, Japanese Patent Laid-Open No. 58-100011. As described in the above publication, it was known before the filing of this application. This conventional grain dryer has a structure in which the throwing port of the elevator is connected to the grain throwing window at the top of one side of the grain storage tank, and a casing-like fall regulating body is provided at the top of the grain storage tank. Then, the grain is forcefully ejected from the throwing port of the elevator and thrown into the grain storage tank.

Problems to be Solved by the Invention By the way, in the conventional grain dryer as described above, the grains thrown from the throwing window of the grain storage tank are concentrated in a far position and fall in large quantities. The grain is not stored evenly, and a lot of grains with low specific gravity such as rice cake and straw fall down, especially near the throwing window facing the side where the grain height is low. For this reason, the grains flowing down from the grain storage tank to the ventilation drying section are not distributed evenly, resulting in uneven drying.

Therefore, the present invention is an attempt to solve the drawbacks of the conventional ones.The present invention aims to eliminate the drawbacks of the conventional ones. It is an object of the present invention to provide a grain distributing device for a grain dryer that can store grain evenly throughout the grain dryer.

Means for Solving the Problem In order to achieve the above object, the present invention has a structure in which an elevator is attached to one side of the main body of the dryer which has a grain storage tank at the top, and the upper throwing port of the elevator is used to store grains. A guide case that is connected to the throwing window on one side of the upper part of the tank, and a guide case that opens in the front and back in the throwing direction is provided in the upper part of the grain storage tank and in the grain throwing path, and the guide case A grain distribution device for a grain dryer, characterized in that an opening/closing plate that opens and closes at a constant speed is provided at the opening end of the body on the side of the throwing window, and fall regulating plates are provided on both sides of the opening end on the opposite side. It is.

Effect Next, its effect will be explained.

The grains conveyed by the elevator 3 are thrown into the grain storage tank 2 from the upper throwing port 4 through the throwing window 5 of the grain storage tank 2. Since the opening/closing plate 12 of the guide casing 11 provided in the grain throwing path repeats opening and closing operations at a constant speed, while the opening/closing plate 12 is closed, the thrown grains are reflected back to the grain storage tank 2.
While the opening/closing plate 12 is open, the thrown grain passes through the inside of the guide casing 11 and is scattered far away. 13, the particles are scattered downward and fall below the fall regulating plates 13, 13. Therefore, the grains thrown into the grain storage tank 2 from the throwing window 5 are stored evenly throughout.

Embodiment The present invention will be described with reference to a preferred embodiment shown in the accompanying drawings.

In the drawing, 1 is a main body of the dryer, 2 is a grain storage tank on the top thereof, and an elevator 3 is attached to the central position on one side of the main body 1 of the dryer. The upper throwing port 4 of the elevator 3 communicates with a throwing window 5 at the top of one side of the grain storage tank 2. 6 is a grain discharge port, and the grain discharge port 6 and the above-mentioned throwing window 5
are alternately communicated with the throwing port 4 of the elevator 3 by a shutter 7. The elevator 3 has a plurality of bucket belts 9 attached to a belt 8 suspended vertically. Although not shown in the drawings, a ventilation drying section is connected below the grain storage tank 2, and further below that, a grain carry-out gutter of the grain removal chamber and the lower part of the elevator 3 are connected.

10 is a grain distribution device, and the grain distribution device 10 includes:
It is arranged in the upper part of the grain storage tank 2 and in the grain throwing path. The grain distribution device 10 is composed of a guide housing 11 that opens in the front and rear directions in the grain throwing direction, and an opening/closing plate 12 is provided at the open end of the guide housing 11 on the side of the throwing window 5, and the opposite side Fall regulating plates 13, 13 are attached to both sides of the side opening end so as to be inclined downward with respect to the grain throwing direction. The bottom plate 14 of the guide case 11 has an angle that gently slopes upward in the grain throwing direction. Reference numeral 15 denotes an electric motor for opening and closing the opening/closing plate 12 at a constant speed, and the electric motor 15 and the opening/closing plate 12 are interlocked via a crank mechanism 16. 17 is an auxiliary fall regulating plate, and the auxiliary falling regulating plate 17 is the opening/closing plate 1.
The auxiliary fall regulating plate 17 is arranged below the throwing window 5 to disperse grains falling near the throwing window 5. Incidentally, the fall regulating plates 13, 13 may have adjustable inclination angles.

In the above embodiment, the grains transported by the elevator 3 and thrown into the grain storage tank 2 from the upper throwing port 4 through the throwing window are transported through the guide housing 11.
near the throwing window 5 side due to the opening/closing operation of the opening/closing plate 12,
Alternatively, they are alternately dropped to distant locations and stored as shown at A and C in FIG. Further, some of the grains that are scattered far collide with the auxiliary fall regulating plates 13, 13 and fall below them, so that they are accommodated so as to form a mountain B between the mountains A and C in the figure. Then, the mountains A, B, and C above become gentle as a whole,
Grains are evenly stored in the grain storage tank 2. Therefore, the grains flow evenly into the ventilation drying section, and uneven drying does not occur.

Effects of the invention In short, the present invention has the above-mentioned technical means, so that the grains thrown from the elevator 3 into the grain storage tank 2 can be stored evenly, and the grains can be transported from the grain storage tank 2 to the ventilation drying section. This has the effect of making it possible to evenly distribute the grains flowing down to prevent uneven drying.
