The outer surface of the cylindrical body 2, that is, each peripheral wall plate 8 and the end caps 13, 14 at both ends, are provided with a large number of fine holes for ventilation. is painted black to increase solar heat collection efficiency. A frame 5 is disposed at the bottom of the greenhouse 1, and a drive support roller 6 and a support roller 6A are mounted on both sides of the frame 5, and a cylindrical body 2 is mounted on the support rollers 6, 6A on both sides. is rotatably supported. By driving the support rollers 6, 6A by an electric motor, engine, etc. (not shown),
The cylindrical body 2 can be rotated in the cylindrical direction at any speed. Furthermore, a wheel 7 is mounted on a shaft at the middle portion of both sides of the frame 5, and a jack 16 is attached to the lower part of one end of the frame 5. By the vertical movement of this jack 16, the frame 5 is moved to the wheel 7.
The cylindrical body 2 can be tilted forward and backward at any desired angle. Further, shielding plates 10 are provided at the middle portions of both sides of the greenhouse 1 so as to be able to rise and fall freely on the inner wall surface of the greenhouse 1, and when the shielding plates 10 on both sides are tilted toward the cylindrical body 2 side, they are biased by a spring 10A. It has become so. When the shielding plate 10 is rotated toward the cylindrical body 2 and the gap between the inner wall surface of the greenhouse 1 and the cylindrical body is closed (FIG. 3A), the inside of the greenhouse 1 is divided into upper and lower parts around the cylindrical body 2. Greenhouse 1
The air inside can pass from the upper part of the greenhouse 1 through the cylinder 2 to the lower part of the greenhouse 1 and circulate through one end of the greenhouse 1. 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. Then, a lotus passageway □20, 20A is connected to the inside of the greenhouse 1 at the upper and lower part of the heating device 3.
is provided so as to be able to be opened and closed freely, and an intake port 21 with an insect repellent net stretched on the outer lower part thereof is provided so as to be able to be opened and closed freely. Next, a method of using the apparatus of the present invention will be explained. When drying grains, etc., first, all the peripheral wall plates 8 of the cylindrical body 2 and the end cover 14 are closed, and the end plate 13 is opened. Then, the jack 16 is raised and the cylindrical body 2 is moved up to the end cover 14.
Tilt your head with the heating device 3 side facing down. 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 pond edge. As the amount of material to be dried 15 increases in the cylindrical body 2, the end cover 13 formed in the same D circular shape is removed from the outer side of the cover 1.
Close one by one starting from 31. The material to be dried 15 is the cylindrical body 2
When the drying material 15 is about half filled, the end cover 13 is closed, the jack 16 is lowered, the cylindrical body 2 is returned to the horizontal position, the surface of the material to be dried 15 is evened out, and the shielding plate 10 is moved to the position shown in FIG. 3A. to fall down like When the weather is bad and solar heat can be utilized sufficiently, only the blower 11 is driven to blow the hot air inside the greenhouse 1 heated by the solar heat from the Yokotsu □ 20.
In addition, the air inside the cylinder that has been warmed by absorbing solar heat from the external surface of the cylinder 2 is circulated through the material to be dried 15 inside the cylinder 2. Then, as the cylinder 2 gradually rotates, the material to be dried 15 inside the cylinder 2 is spread by the peripheral wall plates 8 forming the peripheral surface of the cylinder 2, and is uniformly dried. Exhaust high air. Note that the material to be dried 15 that falls to the lower layer due to weaving has enough time to evaporate the moisture contained therein, and therefore has a tempering effect in the case of drying grains. In addition, good drying can be achieved by adjusting the degree of separation between the intake port 21 and the exhaust port 17 depending on the water content of the material to be dried 15 to perform appropriate hot air circulation. When sufficient solar heat cannot be obtained, such as at night or on cloudy or rainy days, the burner 2 is lit and the air heated by the burner 2 is circulated.
Can be dried. Incidentally, the burner 12 may be configured to automatically ignite and extinguish depending on the temperature inside the greenhouse 1. After drying is completed, the jack 16 is lowered and the end covers 13 are removed one by one starting from the inner one. The dried material 15 is taken out from the cylindrical body 2 by flowing out the material 15 while rotating the cylindrical body 2. Next, when temporarily storing the dried material 15, it is placed inside the cylindrical body 2 as it is. In this case, for example, a cylinder 2 with a diameter of 2.4 and a length of 7.2 can store about 1 hectare of harvested grain. Each peripheral wall plate 8 and end caps 1 at both ends
By closing 3 and 14, mirrors can be prevented. Further, when mixing the low-toxicity insecticide into the material to be dried 15, by rotating the cylindrical body 2, the insecticide can be mixed evenly and reliably killed. In addition, during hot summer months, the temperature inside the greenhouse 1 can be adjusted by covering the top of the greenhouse 1 with a shade such as a shade to moderate the direct sunlight. When the material to be dried 15 is stored for a long period of time, the moisture content may increase, so storage can be ensured by rotating the cylinder 2 from time to time and heating it for a while as described above. Next, when growing seedlings such as paddy rice, as shown in FIG. It rotates and holds each peripheral wall plate 8 in a horizontal position. Then, by standing the shielding plates 10 on both sides of the greenhouse 1 along the inner walls of the greenhouse 1 and rotating the cylindrical body 2, each peripheral wall plate 8 automatically maintains its horizontal position and rotates up and down. move. In this way, seedling growing boxes 19 are placed on each surrounding wall plate 8. In this case, a footboard 18 is provided inside the cylindrical body 2, and the operator works within 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. It should be noted that the cylindrical body 2 having the above-mentioned size can easily raise seedlings for use in a rice transplanter for one hectare. Also, the weather is getting worse, and the greenhouse 1
When the air inside becomes cold, it is heated by the heating device 3 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. [Effect of the invention 1] As is clear from the above explanation, according to the apparatus of the present invention,
The outer surface of the cylindrical body 2 provided in the greenhouse 1 is used as a heat absorber, and shielding plates 10 are provided in the middle part of both sides in the greenhouse 1.
Since the blower 11 for circulating the air inside the greenhouse 1 is provided at one end, the solar heat irradiated into the greenhouse 1 is directly absorbed from the dark side of the cylindrical body 2, and the cylindrical body 2 is heated together with the high temperature air inside the greenhouse 1. increases the temperature of the air by forcing it to pass through the
The material to be dried or stored in the cylindrical body 2 can be efficiently dried and stored with high quality while saving energy.
