DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a ventilation device for a grain tank.
When storing grain, especially raw paddy, in a grain tank,
It is necessary to frequently air and dry the grain. In the present invention, a plurality of porous wall tubes are erected inside the peripheral wall of the tank body, and an annular cylindrical wind chamber and a recirculating wind tube having a unique structure are provided in the lower part of the tank body, thereby providing space between the tubes. The advantages include that air supply and exhaust can be controlled extremely easily, the grain in the tank can be ventilated from multiple directions and the entire grain can be uniformly adjusted to the desired moisture content, and the structure is simple and handling is easy. The aim is to develop and provide a new device.

To explain the present invention with reference to the embodiment drawings, in FIG. 5, reference numeral 1 denotes a tank body consisting of a cylindrical peripheral wall 2 and a circular bottom wall 3, and an annular cylindrical air chamber 4 is provided at the bottom of the main body 1. This grain tank is integrally formed with a rotary transfer wind cylinder 5 provided in the central space.

A plurality of ventilation windows 6a, 6b, 6c, 6b are installed at approximately equal intervals on the inner peripheral wall surface of the annular cylindrical air chamber 4, and the tank body 1 is installed on the upper wall surface of the chamber.
A plurality of porous wall tubes 7a, 7 are provided on the inner surface of the peripheral wall 2.
b, 7c, and 7d are arranged upright at approximately equal intervals, and each tube body 7 is formed to communicate with one of the ventilation windows 6, respectively. And the ventilation window 6...
are provided in the exhaust chamber 8 in the central space, and the exhaust chamber 8 is connected via an air passage 9 to an exhaust fan 10 provided outside the machine.

Next, regarding the rotary wind cylinder 5, the upper half of the cylinder body is provided with an air outlet part 11 that connects and communicates with the ventilation window 6, and the lower half of the cylinder body is connected to the wind cylinder 5 through the air passage 12. It is connected to a blower 13 provided outside. Further, a rotating device 14 is provided at the central joint of the cylindrical body, so that the air exhaust chamber 8 inside the air chamber 4 is formed so that the air outlet portion 11 can freely rotate.

Further, the bottom wall 3 of the tank body 1 is connected to the porous wall surface 1.
5, a grain threshing port 16 is provided on one side of the wall surface, and a grain threshing window 17 for ventilation upward from the lower surface of the porous wall surface 15 is provided on the inner circumferential wall surface of the annular cylindrical air chamber 4. A wind chamber 1 for threshing is provided on the lower side of the porous wall surface 15.
It is connected to 8. 19 is a rotating shaft provided in the rotating wind cylinder 5; 20 is an on-off valve provided in the grain discharging port 16; 21
2 is a grain inlet provided in the tank body, and 22 is a heat generator.

With the above-described configuration, raw grain is supplied into the peripheral wall 2 from the grain input port 21 at the top of the tank body 1 and stored therein, and the blower 13 and the exhaust fan 10 are rotated, and the rotating device 14 is operated to When the air outlet part 11 is rotated and joined to an arbitrarily selected ventilation window 6a, the air from the blower 13 is transferred from the air outlet part 11 of the rotary wind cylinder 5 to the porous wall tube body 7 through the ventilation window 6a.
a, and the wind flows into the grain layer in the peripheral wall 2 from the porous wall of the tube body 7a.

At this time, the rotation of the exhaust fan 10 creates a negative pressure state in the lower ventilation chamber 8, and each porous wall tube body 7 communicates with each ventilation window 6b, 6c, 6d opened in the chamber 8.
b, 7c, and 7d respectively absorb the high-pressure air ejected from the porous wall tube 7a in the direction of the dotted arrow shown in FIG. 2 and discharge it to the outside of the machine.

Then, after a predetermined period of time has elapsed, the rotating device 1
4 to open the air outlet portion 11 to the next ventilation window 6b.
Rotate and join. Through this joining operation, ventilation is created between each pipe body in the direction of the arrow shown by the dashed dotted line in FIG. It should be ventilated and dried.

When the grain stored in the tank body 1 is discharged to the outside of the machine, the rotating device 1 is used to discharge the grain stored in the tank body 1 to the outside of the machine.
4 to connect the air outlet portion 11 to the air blowing window 17 provided in the annular cylindrical air chamber 4, rotate the air blower 13, and open the grain threshing on/off valve 20 provided on the bottom wall 3. In FIG. 4, the wind from the blower 13 flows into the grain threshing air chamber 18 at the lower part of the porous wall surface 15 through the recirculating wind cylinder 5, and the wind blows upward from the lower surface of the porous wall surface 15 through the grain threshing port 16. The grain in the grain layer is floated from the side, conveyed, and sequentially discharged outside the machine.

Incidentally, if the opening angle of the porous wall surface 15 of the floor section 3 is inclined so that the wind is blown out in an inclined direction toward the grain discharging port 16, the grain discharging operation can be carried out particularly smoothly and quickly.

Since the present invention has the above-described structure and operation, by rotating the rotary wind cylinder in one direction and sequentially joining its air outlet to the annularly arranged ventilation window, it can be attached to the inner surface of the peripheral wall of the tank body. Air supply and exhaust between each installed pipe body can be controlled extremely easily.
In addition, since the direction of the airflow changes sequentially to ventilate the stored grain from multiple directions, the entire amount of the stored grain can be reliably adjusted to the desired moisture content uniformly and without unevenness. Moreover, its structure is simple and its handling is extremely easy. Furthermore, by rotatably joining the air outlet to the air window of the annular cylindrical air chamber, the grains stored in the tank body can be carried by flight by the wind. Can be quickly and smoothly discharged from the machine.

Therefore, grain tanks have the remarkable effect of greatly improving their storage performance and promoting increased utilization.
