[Prior art and its problems]

 Conventionally, small grains such as rice, wheat, beans, and corn that are stored in bulk in a container are made of dense materials such as iron plates. The bottom and peripheral walls are mainly dedicated containers with ventilation function on the bottom wall. The mainstream is that it is stored inside and dried. Therefore, considering the harvesting time of grains, drying dozens of expensive dedicated containers would not only increase production costs but also make management difficult. In other words, rice, wheat, beans, corn, etc. are not harvested throughout the year, but only for a few months. They are used only at this harvest time and not throughout the year. Therefore, the period of non-use is longer than the period of use (season of harvesting of cereals), and therefore high production is brought about in view of production volume of cereals, securing a storage place during non-use and management thereof. It is also possible to use this special container to store large agricultural products such as onions, potatoes, vegetables, etc., just like the ready-made grain container, but since the bottom and surrounding walls are made of steel plates, etc. Since it has its own weight and cannot be folded into a compact flat shape after being used like a grain container, it is stored during periods other than the harvesting period due to inconvenience. Also, when accommodating multi-purpose varieties, depending on the varieties, there is soil adhesion etc., it is necessary to consider contamination etc., and it is difficult to clean the entire container as a practical problem, so the range of use of the dedicated container is It is usually very limited.

Then, if the ventilation device ventilates the ventilation duct, the air is ventilated while the air passes upward from the top surface or the peripheral wall of the box body through the grain deposition layer that is stored in the bulk accumulation state.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A ventilation device 1 is a box-shaped box body in which the inside is formed in a hollow shape with an appropriate size and height so that the ventilation device 1 can fit in the inner bottom of a ready-made grain container 2. At least the upper surface of 1a is formed in a mesh shape or a porous shape in which a large number of ventilation holes are scattered innumerably, and a ventilation duct 1b is integrally or detachably connected to the upper surface or the peripheral surface at an appropriate place, and a connection port 1c is provided. Grains such as rice, wheat, beans, corn, etc., which are provided and configured, are placed in the bottom of the grain container 2 via the inner bag 3 and stored in a piled state, and air is passed from the bottom to the top of the pile layer. While ventilating.

The box body 1 is formed in an inner hollow shape having an appropriate height according to an inflow amount of air, which is a rectangular shape having a flat shape which is slightly smaller than the inner dimension of the grain container 2 so that it can be easily accommodated in the grain container 2. The upper surface thereof is composed of a perforated plate 6 having a large number of ventilation holes 5 interspersed therein. The ventilation hole 5 should have a diameter such that even small grains such as rice and wheat will not fall into the box 1a. The ventilation hole 5 is appropriately changed depending on the aeration resistance of the grain, which varies depending on the variety (particle size, etc.) stored and accumulated in the container 2, but the opening rate of about 5% to 30% is desirable. The perforations may be formed not only on the upper surface of the box 1a but also on the peripheral wall. Then, a connection port 1c is provided at an appropriate place on the upper surface where the ventilation hole 5 is provided, that is, a central portion on one long side in the drawing, and a ventilation duct 1b that connects to the existing ventilation equipment 7 is vertically installed.

By the way, when the grain container 2 has an inner size (mm) of 1.245L × 1.530W × 1.100H and the height of the sediment layer of the grain 4 (mm) is 800 to 900, the size of the box 1a ( mm) is 1.240L × 1.525W × 120H, and the diameter of the connection port 1c provided on the upper surface is 150φ when the wind speed is 15m / s, so that the air flow (ventilation) is 800-900. It can be ensured almost uniformly over the whole grain 4 sedimentary layer. The amount of dry air is set appropriately according to the type of grain 4 and its drying speed (time), but within the range of 0.1 to 0.5 m ³ / s per 1 t of grain amount (content amount) stored in container 2. Good to set. The ventilation duct 1b is formed to have a length such that it projects from the upper opening of the grain container 2 in a state where it is connected to the connection port 1c and provided with a connection flange 8 on the upper edge thereof, as shown in the example of FIG. In this way, the flexible duct 7b connected to the distribution duct 7a of the existing ventilation equipment 7 can be connected. Reference numeral 9 in the figure is a support member that is vertically installed inside the box body 1a, and is supported and reinforced so that the upper surface is not deformed or damaged by the load of the grain 4. In the figure, 10 is a metal fitting for fixing the container attached to the four corners of the box 1a. After the box 1a is stored in the inner bottom of the container 2, the box 1a is bound and fixed to the inner bottom of the container 2 by the binding tool 11. Then, when the container is transported by a forklift or the like, the stored grains are discharged, or the container is replaced with another container, the box 1a flaps in the container, shifts, or pops out of the container. So that it doesn't get in the way.

Then, the usage of the air blower 1 configured as described above will be explained. As in the conventional procedure, the inner bag 3 is housed in the grain container 2 and the box body is placed on the inner bottom of the inner bag 3. After placing 1a and connecting it to the connection port 1c of the box 1a, connect the standing ventilation duct 1b to the flexible duct 7b of the existing ventilation equipment 7, and then put small grains 4 such as beans and corn in the inner bag 3. Store. When the ventilation duct 6 is ventilated by the ventilation facility 6, air is blown upward from the ventilation holes 5 on the upper surface of the box 1a and the grains 4 stored in the piled state are passed upward while passing through the sediment layer. Ventilation is performed to dry it.

In the above embodiment, an example of ventilation drying of the grain 4 was described in detail. However, in the case of dehumidifying and drying, if the ventilation duct 1b is connected to the existing suction equipment, the air will move down the grain 4 accumulation layer. It can ventilate while passing.

[Effect of the device]

 Since the ventilation device for drying grains of the present invention is constructed as described above, it has the following operational effects. Place the inner bag in the grain container, place the box on the inner bottom of the inner bag, connect the ventilation duct that is installed upright to the connection port of the box and connect it to the existing ventilation equipment, and then use the ventilation equipment to supply air. If the duct is ventilated, air can be ventilated and dried while the air passes upward from the top surface or the peripheral wall of the box through the grain sediment layer that is stored in bulk and accumulated. Therefore, without changing the shape and structure of the ready-made grain container itself, which is widely used for various purposes such as storage and transportation of grains, it is stored in the inner bottom of the container via an inner bag. By connecting to ventilation equipment, small grains such as rice, wheat, beans, and corn that are stored in bulk in the inner bag can be dried. It was possible to provide a convenient simple ventilation device that can effectively dry small grains such as beans and corn that are stored in bulk in a grain container via an inner bag.
