DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus that can be used for drying and storing agricultural products, particularly grains.

BACKGROUND OF THE INVENTION Conventionally, there are various drying apparatuses for grains, etc., but all of them are used only for drying, and moreover, they dry using air heated by a burner or the like.

OBJECTS OF THE INVENTION The present invention has been made with attention to these points, and includes rotatably providing a ventilated cylindrical body for storing items to be dried or stored in a transparent greenhouse. Inside the greenhouse, there is a plow 7, a burner, a movable shielding board, and a suction system that can be opened and closed.
A drying and storage device that is equipped with an exhaust port, moves air inside the greenhouse using a plow 7, and uses solar thermal energy and hot air to dry and store grains and other materials to be dried or stored. It provides:

Example An embodiment of the present invention will be described below with reference to the drawings.

This drying and storage device is composed of a greenhouse 1, a cylindrical body 2, and a heating device 3.

The greenhouse 1 is constructed of a structure whose outer wall can be completely sealed with a transparent material such as transparent plastic or glass, and is configured to effectively collect solar energy, that is, direct heat exchanger or radiant heat, and prevent it from being dispersed. There is.

A plurality of exhaust ports 17 are provided at the bottom of both sides of the greenhouse 10 so that they can be opened and closed, and each exhaust port 17 is covered with an insect screen (not shown).

The cylindrical body 2 has a plurality of annular support frames 4, and a plurality of peripheral wall plates 8 are provided on the inner circumferential surface of the cylindrical body 2 so as to be rotatable, openable and closed by a support shaft 9, and both end surfaces of the cylindrical body 20 End covers 13 and 14, each consisting of a plurality of concentric circles, are provided on the sides so as to be openable and closable.

The outer surface of the cylindrical body 2, that is, each peripheral wall plate 8 and the end covers 13 and 14 at both ends, is provided with a large number of fine holes for ventilation. 14 is painted black to increase solar heat collection efficiency.

Two frames 5 are disposed at the bottom of the greenhouse 1, and drive support rollers 6 and support rollers A are mounted on both ends of the frame 5, and support rollers 6A and 6A are mounted on both sides of the frame 5.
A cylindrical body 2 is rotatably supported on top.

and an electric motor (not shown) for the support roller 6.6A;
The cylindrical body 2 can be rotated at any speed by being driven by an engine or the like.

Further, a wheel 7 is mounted on an axis at the intermediate portion of both sides of the frame 50, and a lower jack 1 is mounted at one end of the frame 5.
6 is installed.

By moving the jack 16 up and down, the frame 5 can be tilted about the wheel T, and the cylindrical body 2 can be tilted at an arbitrary angle in the front-rear direction. A shielding plate 10 is provided to be able to rise and fall freely, and the shielding plates 10 on both sides are biased by springs 10A.

When the shielding plate 10 is rotated inward and set horizontally, the inside of the greenhouse 1 is divided into upper and lower parts around the cylindrical body 2.

The heating device 3 is disposed at one end of the greenhouse 1, and includes a blower 11 at the bottom and a burner 12 at the top.

Communication ports 20.20A communicating with the inside of the greenhouse 1 are provided at the upper and lower parts of the heating device 3, and an air intake port 21 with an insect repellent screen is provided at the lower part of the outside and can be opened and closed. ing.

Next, a method of using the apparatus of the present invention will be explained.

When drying grains, etc., immediately close all the peripheral wall plates 8 and the end caps 14 of the cylindrical body 2, open the end caps 13, raise the jack 16, and close the cylindrical body 2 with the end caps. 14 with the heating device 3 side facing downward.

Then, the material to be dried 15 such as grains is gradually introduced into the cylindrical body 2 from the opening side where the end cover 13 is opened.

On the other hand, while the cylindrical body 2 is rotated by the driving support roller 6, the dried material 15 is sent toward the other end.

As the number of objects 15 to be dried increases in the cylindrical body 2, the concentrically formed end covers 13 are closed one by one starting from the outer cover 131.

When about half of the material to be dried 15 is in the cylindrical body 2, the end cover 13
is completely closed, and the jack 16 is lowered,
The cylindrical body 2 is returned to a horizontal position so that the surface of the material to be dried 150 is made uniform.

When the weather is good and sufficient solar heat can be used, only the blower 11 is driven and the greenhouse 1 heated by the solar heat is heated.
The hot air inside is circulated through the communication port 20 and through the dried material 15 inside the cylindrical body 2.

At this time, when the shielding plate 10 is placed in the collapsed state (FIG. 3A) and the intake port 21 and the exhaust port 17 are completely closed,
Only the air inside the greenhouse 1, which does not allow outside air to enter, is circulated, and 1
However, when the intake port 21 and the exhaust port 17 are slightly opened, some of the air inside the greenhouse 1 is exhausted from the exhaust port 17 due to the air taken in from the intake port 21, resulting in a state of partial circulation and partial exhaustion.

Furthermore, when the intake port 21 and the exhaust port 17 are fully opened,
The amount of outside air taken in from the intake port 21 increases and the amount of outside air taken in from the intake port 21 increases.
7, all the air within temperature 1 is exhausted.

Then, as the cylinder 2 gradually rotates, the material to be dried 15 inside the cylinder 2 is removed from each peripheral wall plate 8V- which forms the peripheral surface of the cylinder 20.
Therefore, the drying device is driven and dried uniformly, and drying is promoted by discharging humid air from the exhaust port 17.

It should be noted that the material to be dried 15 that falls to the lower layer due to the driving is given enough time to evaporate the moisture contained therein, and therefore has a tempering effect in the case of drying grains.

Depending on the moisture content of the material to be dried 15, the intake port 21
Good drying can be achieved by adjusting the degree of opening between the air outlet and the exhaust port 17 to perform appropriate temperature circulation.

When sufficient solar heat cannot be obtained, such as at night or on cloudy or rainy days, drying can be achieved by lighting the burner 12 and circulating the air heated by the burner 12, partially circulating and partially discharging the air. can.

The burner 12 may be turned on and off automatically depending on the temperature inside the greenhouse 1. After the drying is completed, the jack 16 is lowered to remove the end covers 13 one by one starting from the inner one, and the cylindrical The material to be dried 15 is flowed out while rotating the body 2, and the material to be dried 15 is taken out from the cylinder body 2. Next, when the dried material to be dried 15 is temporarily stored, it is stored in the cylinder 2 as it is. Just do it.

In this case, for example, the cylindrical body 2 with a diameter of 2.4 m and a length of 7.2 m can store about 1 hectare of harvested grain.

At this time, the shielding plate 10 may be kept in an upright state.

In addition, each peripheral wall plate 8 of the cylindrical body 2 and the end covers 13, 1 at both ends
By closing 4, you can prevent rodent damage.

When mixing low-lying insecticides into the dried material 15,
By rotating the cylindrical body 2, it is possible to uniformly agitate and kill insects reliably.

During the hot summer months, the temperature inside the greenhouse 1 can be adjusted by covering the top of the greenhouse 1 with a shading material such as a shading material to reduce the amount of direct sunlight.

When the material to be dried 15 is stored for a long period of time, the moisture content may become high, so the storage can be ensured by rotating the cylindrical body 2 from time to time and heating and drying it for a while as described above. can.

Next, when growing seedlings such as paddy rice, as shown in Fig. 3B, the end caps 13 and 14 at both ends of the cylindrical body 20 are removed, and each peripheral wall plate 8 is opened and the support shaft 9 is used as the center. It rotates and holds each peripheral wall plate 8 in a horizontal position.

Then, by placing the shielding plates 10 on both sides of the greenhouse 1 in an upright position along the inner wall of the greenhouse 1 and rotating the cylindrical body 2, each peripheral wall plate 8 rotates while automatically maintaining its horizontal position. Move up and down.

In this way, the seedling growing box 19 is placed on each peripheral wall plate 8.

In this case, a footboard 18 is provided inside the cylindrical body 2, and the operator works inside the cylindrical body 2.

By slowly rotating the cylindrical body 2, the seedling growing box 19 can be rotated and moved up and down together with each peripheral wall plate 8, so that each seedling growing box 19 can receive sunlight evenly.

In this way, the space within the greenhouse 1 is fully utilized to raise seedlings.

In addition, with the cylindrical body 2 of the above-mentioned size, it is possible to easily raise one hectare of seedlings for a rice transplanter.

When the weather gets bad and the air inside the greenhouse 1 becomes cold, the heating device 3 heats it to prevent cold damage.

Furthermore, it becomes possible to cultivate summer crops in winter, and it can also be used for greenhouse cultivation of short-term horticultural crops.
