Description

[Detailed description of the invention] This utility model relates to a bucket for a grain lifting machine in a circulating grain dryer. In a circulating grain dryer, a process for uniformly depositing grain in a storage tank is required as a condition for uniform drying.

Conventionally, grain distribution devices such as screw conveyors have generally been used as a method for this purpose. Since the above-mentioned device is functionally installed above the storage tank, it causes various inconveniences in the structure, manufacturing and assembly of the dryer, handling, etc., and also increases costs, so improvements are desired. On the other hand, there has been an attempt to deposit scattered grain directly into a storage tank by the throwing action of a bucket from the top of the grain lifting machine. This is a method of distributing grain by increasing the throwing angle of the bucket and increasing the throwing distance of the grain, and is attracting attention because it eliminates the need for the grain distributing device commonly found in circulating dryers. However, as dryers have become larger, in order to effectively and evenly deposit grain directly from the grain lifting machine into the storage tank, buckets with different throwing angles are sequentially placed on multiple endless belts. At present, there is a concern that problems such as the trouble of putting on the bucket bag and problems such as incorrect wearing of the bucket bag are desired, and improvements are desired.

The present invention is a bucket that has been devised to take advantage of the advantages of the above-mentioned throwing type grain distribution system and to improve the disadvantages thereof.

Therefore, in the present invention, a plurality of buckets having different throwing angles are formed in rows and attached to the endless belt of the grain lifting machine. As a result, the grains scattered by the throwing action from the top of the grain lifting machine can be distributed effectively and evenly directly into the storage tank.

The present invention will be explained below based on embodiments. FIG. 1 is a perspective view of a bucket tot in which a plurality of bucket tots each having a different throwing angle are formed in a horizontal row. FIG. 2 is a side view of the bucket shown in FIG. 1. θ ₁ , θ
₂ , θ ₃ is the vertical wall 1 and the inclined front wall 2a, 2b, 2c
Indicates the throwing angle for each. Further, as an embodiment of the present invention, three buckets having a throwing angle of θ ₁ <θ ₂ <θ ₃ are formed in a row. FIG. 3 is a cross-sectional view of a circulating grain dryer 11 equipped with the grain lifting machine 6, in which the bucket 5 shown in FIGS. 1 and 2 is attached to the endless belt 4 of the grain lifting machine 6, and The conveyance system is shown.

In FIG. 3, grains input from a hopper 7 are fried to the top of the grain lifting machine in a bucket 5 as shown in FIGS. 1 and 2. Then θ ₁ , θ ₂ , θ
_Each throwing action is generated from the throwing angle of θ ₁
Grain is thrown out from the bucket having a bucket in the throwing direction 9, and it scatters and falls. Similarly, at θ ₂ , the grains are distributed in the throwing direction 10, and at θ ₃ , they scatter and fall in the throwing direction 10, and the grains are deposited almost uniformly in the storage tank 12. In addition, during drying, the grains flow down from the storage tank 12 through the drying section 13, are horizontally conveyed to the bucket 5 by the screw conveyor 14, are fried, and are sequentially distributed in the storage tank 12 as described above. Circulate and dry.

As described above, by forming a plurality of buckets of the present invention with different throwing angles in horizontal rows on the bucket used in the grain lifting machine of the circulating grain dryer and attaching them to the endless belt, it is possible to not only fry grain but also distribute the grain. It has now become possible to perform grain functions at the same time. Furthermore, the grain rationing device found in conventional circulating grain dryers is not required, and the overall structure is extremely simplified, resulting in a more compact structure and lower costs. On the other hand, when attaching the bucket according to the present invention, since the same kind is attached to the endless belt, there is no possibility of incorrect attachment, and the advantages of the above-mentioned throwing type grain distribution system can be fully utilized.
