Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a grain rotation dispersion device for a circulating grain dryer, and in particular, it is capable of achieving good dispersion throughout the entire storage area, and also improves ease of assembly and safety. This invention relates to a grain rotation and dispersion device for a circulating grain dryer that is improved and reduces costs.

[Conventional technology]

Conventionally, in circulating grain dryers, as a means of dispersing the grain lifted from the bottom of the dryer into a storage section, a rotary dispersion device that disperses the grain by rotation or a rotary dispersion device that is fixedly installed within the throwing range of the grain being thrown is used. There are some types that are equipped with a dispersion plate. The rotary dispersion device is installed in parallel with an upper screw mechanism for cross-feeding, and the fixed dispersion plate is installed in a dryer having a throwing type grain lifting machine. We are trying to achieve good dispersion.

[Problem that the invention attempts to solve]

However, as described above, the rotary dispersing device is heavy because it has an upper screw mechanism.
Since it is installed at a high place inside the dryer, it is difficult to assemble and poses a safety problem, and it also takes time and effort to process leftover grains, resulting in high mechanical costs. With a dispersion plate fixed within the throwing range, if you adjust the position of the dispersion plate so that more of the grain is dispersed to the opposite side of the storage section to the side opposite to the dumping port, the side of the dumping port will be lower when a small amount is loaded. . This caused hot air to blow through in the drying section, which hindered drying. In order to correct this, when the position of the dispersion plate was adjusted so that more of the material was dispersed toward the outlet, the outlet became too high, making it difficult to inject the required amount. As described above, with a fixed dispersion plate, the dispersion state is uneven, and the position must be adjusted depending on the amount of spread, which is time-consuming and difficult to achieve uniform dispersion.

[Purpose of invention]

Therefore, the object of this invention is to realize a grain rotation dispersion device for a circulating grain dryer that can achieve good dispersion within the storage section, improve assembly and safety, and reduce costs.

[Means for solving problems]

In order to achieve this object, this device distributes the grains thrown into the storage section from the dumping port of the grain lifting machine into the storage section by rotating a rotating distribution plate. The rotary dispersion plate is provided at the rotary dispersion plate, and a downward guide member is provided to direct the thrown grain toward the rotary dispersion plate.

[Effect]

According to this invention, the grain thrown from the grain lifting machine throwing port is directed by the downward guide member to the rotating distribution plate provided in the throwing direction of the grain. Thereby, the grains thrown into the storage section are once received by the rotating distribution plate, and then uniformly dispersed within the storage section by the rotation distribution plate.

〔Example〕

Next, an embodiment of this invention will be described in detail based on the drawings. 1 and 2 show an embodiment of this invention. In the figure, reference numeral 2 denotes a circulating grain dryer, which has a storage section 4, a drying section 6, and a grain collecting section 8. In the dryer 2, grains put into a hopper 10 are lifted up by a grain lifting machine 12 and thrown into the storage section 4 through a dumping port 14. The grains that flow down from the storage section 4 to the drying section 6 and are dried are collected in the grain collection section 8 and sent to the lower part of the grain lifting machine 12. The grain lifting machine 12 repeats the cycle of lifting the grains and dumping them back into the storage section 4 as described above, thereby drying the grains.

Inside the storage section 4, there is a dumping port 14 of the grain lifting machine 12.
A rotating dispersion plate 16 is provided which rotates and disperses grains thrown from the machine. The rotating dispersion plate 16 is composed of a disk-shaped flat portion 18 and an annular band-shaped inclined portion 20 provided on the outer peripheral edge of the flat portion 18, forming a tray-shaped dispersion surface 22. This rotating distribution plate 16
is fixed to the rotating shaft 26 of the motor 24, and the motor 24 is connected to the ceiling 3 of the storage section 4 via the support 28.
Fixed to 0. At this time, the rotary dispersion plate 16 is positioned within the throwing range of the grains to be thrown, the dispersion surface 22 faces in the throwing direction (for example, the direction of arrow B), and the support 28 is placed on the ceiling 30. To be fixed.

The dispersion surface 22 of the rotating dispersion plate 16 has a discharge opening 1.
A downward guide member is provided to direct the grain thrown from 4. In this embodiment, a jump table-like lower guide plate 32 for guiding the falling grains to the dispersion surface 22 is provided below the throwing range indicated by the dashed line arrow A in front of the dispersion surface 22. Furthermore, if necessary,
Upper guide plate 3 that guides the grains passing above the dispersion surface 22 above the throwing range shown by the solid line arrow C to the dispersion surface 22
4 may be provided. By means of this lower guide plate 32 and an upper guide plate 34 provided as necessary, the thrown grains are focused at the center of the throwing range shown by the thick arrow B and directed toward the dispersion surface 22 of the rotating dispersion plate 16. This lower guide plate 32 or upper guide plate 3
4 may be further provided with similar guide plates (not shown) on the left and right sides of the shooting range, if necessary. That is, other guide members may be provided to focus the throwing range of the grains and direct them to the dispersion surface 22.

Next, the action will be explained.

The grains thrown into the storage section 4 from the throwing port 14 of the grain lifting machine 12 are thrown in the directions shown by the arrows A, B, and C. The amount of grain thrown in the direction shown by each arrow in this throwing range is A≈C<B.

Grain falling in front of the dispersion surface 22 below the throwing range shown by arrow A is bounced up by the lower guide plate 32 and guided in the direction shown by arrow B. Grain passing above the dispersion surface 22 above the throwing range shown by arrow C collides and falls by an upper guide plate 34 provided as necessary, and is guided in the direction shown by arrow B.
As a result, the grains to be thrown are focused at the center of the throwing range indicated by the arrow B, where the amount of grain thrown is large, and guided to the dispersion surface 22 of the rotating dispersion plate 16 facing in the throwing direction.

The guided grains are once received on a tray-shaped dispersion surface 22. Since the rotating distribution plate 16 is rotated by the motor 24, the grains on the distribution surface 22 are dispersed in all directions shown by the dashed arrow D.

Therefore, the particles can be uniformly distributed throughout the storage section 4 without causing the inconvenience caused by conventional fixed dispersion plates. Furthermore, since no upper screw mechanism is provided, ease of assembly and safety during operation can be improved, costs can be reduced, and leftover grain disposal is easy.

[Effect of idea]

As described above, according to this invention, the grain thrown into the storage section from the grain lifting machine throwing port is directed by the downward guide member to the rotating distribution plate provided in the throwing direction of the grain. Therefore, the thrown grains are once received by the rotating distribution plate and then dispersed throughout the storage section by the rotating distribution plate. Therefore, unlike conventional fixed distribution plates, the grains thrown out depending on the position or the degree of tensioning are not unevenly distributed within the storage section, and can be favorably dispersed throughout the storage section. Furthermore, since the upper screw mechanism for traversal feeding is not provided, but only the downward guide member is provided, the assembly work is easy, and the ease of assembly and safety can be improved, and costs can be reduced. In addition, since there is no upper screw mechanism, it is easy to dispose of leftover grains.
