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 cylindrical fall regulating body is provided at the top of the grain storage tank. Grain is forcefully ejected from the throwing port of the elevator and thrown into a 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 grains are not stored evenly, and a lot of grains with low specific gravity, such as rice cake and straw, fall down, especially in the vicinity of 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 intended to eliminate the drawbacks of such conventional devices, and to provide a grain distribution device in a grain dryer that can store grain evenly throughout the entire grain storage tub when it is thrown from the throwing port of the elevator through the throwing window of the grain storage tub.

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 falling diffusion plate is provided in the upper part of the grain storage tank and in the grain throwing path, which is connected to the throwing window on one side of the upper part of the tank, and which swings back and forth within a certain angle range from a substantially horizontal position. This grain distribution device for a grain dryer is characterized in that an auxiliary fall regulating plate for colliding grains is provided in front of the falling diffusion plate.

Next, its action 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. On the other hand, the falling diffuser plate 1
1 is reciprocated in a fixed angle range from a substantially horizontal position, the grains being thrown are guided by this fall diffusion plate 11 and are dispersed to positions far from and near the throwing port 4 and fall evenly. can be made,
Further, the auxiliary fall regulating plate 12 can reflect some of the grains that are scattered far away and guide them downward. Then, the above-mentioned falling diffusion plate 1
1 and the auxiliary fall regulating plate 12, the grains thrown into the grain storage tank 2 are stored evenly.

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, a ventilation drying section is provided below the grain storage tank 2, and a grain unloading chamber is provided further below, and the grain carrying out gutter of the grain unloading chamber is connected to the lower part of the elevator 3. There is.

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 includes a fall diffusion plate 11 and an auxiliary fall regulation plate 12, and the fall diffusion plate 11 has a pair of left and right brackets 13, 13.
It is pivotably supported in between so as to be vertically movable, and can be reciprocated from a substantially horizontal position within a certain range of angles up and down with respect to the grain throwing direction. 14 is an electric motor for the swinging, and 15 is a swinging connecting rod. The auxiliary fall regulating plate 12 is attached to a position in front of the fall diffusion plate 11 so as to hang diagonally forward. The auxiliary fall regulating plate 12 may have its inclination angle adjustable, and its hanging extension length adjustable, or may have a configuration that combines both. Usually, in the case of paddy, it is appropriate to make the auxiliary fall regulating plate 12 short and its slope close to vertical, whereas in the case of wheat, it is appropriate to make it long and its slope close to horizontal.

In the above embodiments, 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 5 fall through the falling diffusion plate 1.
1, they fall evenly distributed in the front-back direction and are housed as shown at A and C in FIG. Also, some of the grains flying forward collide with the auxiliary fall regulating plate 12 and fall below, so that they are accommodated so as to form a mountain B between the mountains A and C in the figure. The mountains A, B, and C become gentle as a whole, and the grains are stored evenly 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.
