Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In order to achieve the above-mentioned object of the invention, Figure 1-4As shown, the utility model provides a multifunctional grain air-drying bin, including a ventilation pipe of a multifunctional grain air-drying bin body 9, the side of the multifunctional grain air-drying bin body 9 is connected with a ventilation pipe, and the ventilation pipe passes through the multifunctional grain air-drying bin body 9, the centrifugal fan is installed at one end of the ventilation pipe away from the multifunctional grain air-drying bin body 9, and the centrifugal fan is electrically connected to an external power supply through a power line, and a multifunctional grain air-drying bin bottom support frame 16 is arranged at the bottom of the outer net tube 10 by welding, and a funnel 14 is arranged at the bottom of the outer net tube 10 and on the inner side of the multifunctional grain air-drying bin bottom support frame 16, and a bin body discharge port 15 is opened at the bottom of the funnel 14;

[0041] In the present embodiment, the multifunctional grain air-drying bin is first placed at the position where it is needed through the bottom support frame 16 of the multifunctional grain air-drying bin, and then the grain with high moisture content to be air-dried is put into the interior of the multifunctional grain air-drying bin body 9, and then the power switch of the centrifugal fan is turned on. At this time, the centrifugal fan can blow or exhaust air to the interior of the multifunctional grain air-drying bin body 9 through the ventilation pipe, and the moisture of the grain can be taken away by the flowing air flow, thereby realizing the air drying of the grain stored in the interior of the multifunctional grain air-drying bin body 9. After the air drying is completed, the bin body discharge port 15 is opened to discharge the air-dried grain. The bin body discharge port 15 is in a sealed state during air drying, and sealing can be achieved by a rubber plug or the like.

[0042] Preferably, the multifunctional grain air-drying bin body 9 includes an outer mesh tube 10, an inner mesh tube 11 is arranged inside the outer mesh tube 10, and the outer mesh tube 10 and the inner mesh tube 11 are fixedly connected by an inner mesh tube support frame 13, and the two ends of the inner mesh tube support frame 13 are respectively welded to the inner wall of the outer mesh tube 10 and the outer wall of the inner mesh tube 11, wherein the ventilation pipe passing through the outer mesh tube 10 is connected to the inner mesh tube 11 and is in a communicating state with the inner mesh tube 11, so that through the setting of the inner mesh tube 11, the wind blown through the ventilation pipe can be transported to more locations outside the outer mesh tube 10 or the air in the inner mesh tube 11 can be extracted to form a negative pressure, so that the grain stored in the outer mesh tube 10 can be air-dried more evenly.

[0043] Preferably, a branch net tube 12 is fixedly arranged around the inner net tube 11, and the interiors of the inner net tube 11 and the branch net tube 12 are respectively hollow structures, and the two are in a connected state. In this way, through the setting of the branch net tube 12, the centrifugal fan can be blown into the inner net tube 11 and transported more evenly to the interior of the grain to be air-dried, thereby making the air-drying of the grain more uniform and thorough.

[0044] Preferably, a plurality of through holes are provided on the outer net cylinder 10, so that the food stored inside the outer net cylinder 10 can be in contact with the external air, and the food can be dried by the external natural wind, so that the food can be dried more evenly and quickly;

[0045] Preferably, the inner net tube 11 and the branch net tube 12 are also respectively provided with a plurality of through holes. Thus, the air flow blown in or drawn out by the centrifugal fan is made more uniform through the provision of the through holes, thereby enabling the grain to be dried more evenly and thoroughly.

The centrifugal fan I6 is connected to the bottom of the inner mesh tube 11 through the ventilation pipe I7, which realizes the blowing or exhausting effect. Through this design, a faster wind speed flow can be better formed inside the outer mesh tube 10, and then the moisture stored in the grain inside the outer mesh tube 10 can be taken away more quickly, so that the grain can be dried more quickly.

[0048] In this embodiment, the centrifugal fan can be realized by using the centrifugal fan equipment of the prior art, so it will not be described in detail in this technical document. When in use, the two centrifugal fans are installed with opposite air outlets to achieve different exhaust and blowing effects.

[0050] In this embodiment, when the grain is air-dried through the multifunctional grain air-drying bin, the grain can be added to the interior of the elevator feed port 2, and then the grain to be air-dried is lifted by the elevator body 1, and then discharged through the elevator discharge port 3, and then discharged into the interior of the outer net cylinder 10 to achieve grain air-drying. Through this design, the need for manual addition of grain is avoided, which is faster and more convenient.

[0051] As another embodiment of the present technical solution, a movable belt conveyor 4 is provided at the bottom of the bin body discharge port 15, and the output end of the belt conveyor 4 is located at the side of the elevator feed port 2;

[0052] In this embodiment, when the grain is air-dried through the multifunctional grain air-drying bin, the bin discharge port 15 at the bottom of the multifunctional grain air-drying bin is not in a sealed state, so that the grain input through the elevator body 1 will be discharged through the bin discharge port 15 after a certain period of air-drying, and then transported to the inside of the elevator feed port 2 through the belt conveyor 4, and then transported to the inside of the outer net cylinder 10 through the elevator body 1, thereby realizing the circular air-drying of the grain, which can make the air-drying of the grain faster.

[0053] Optionally, the elevator can be implemented by various elevators of the prior art, such as the patent document with application number CN202020604091.0 discloses a material elevator, the patent document with application number CN202221543734.0 discloses a material elevator, etc., all of which can realize the lifting of materials.
