[0001] The utility model relates to the technical field of grain bin drying, in particular to a hot air and microwave grain bin drying device. Background Art

[0002] China is a large agricultural country, producing a large amount of grain every year. A part of this grain is for use, and the other part is for storage for emergencies, that is, a special building for storing grain, which is used to store a large amount of grain. Most of the existing devices are difficult to dry the grain stored in the grain bin, and the drying of the grain stored in the grain bin is not thorough.

[0003] During the plum rain season, it is very easy for the grain to rot due to excessive humidity, resulting in waste of grain. Therefore, it is necessary to design a grain bin drying device that can easily dry the grain stored in the grain bin during the plum rain season. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings, and a hot air and microwave grain bin drying device is proposed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Example 1

[0023] Reference Figures 1-4 , a hot air microwave granary drying device, a hot air microwave granary drying device, including an arc ring 1, and there are two arc rings 1 symmetrically arranged left and right. The middle position of the outer surface of the left arc ring 1 is provided with an L-shaped ventilation pipe 2. The middle position of the left side of the L-shaped ventilation pipe 2 is provided with a hot air blower 3. Both the upper and lower sides of the inner wall of the arc ring 1 are provided with annular grooves 4, and the outer surface of the annular groove 4 is provided with an annular slider 5;

[0024] The inner wall of the annular slider 5 is provided with a fixed circular plate 6. The middle position of the upper surface of the fixed circular plate 6 is provided with a motor 7. The power output end of the motor 7 is provided with a movable rotating rod 8. The bottom position of the outer surface of the movable rotating rod 8 is provided with a fixed rod 9. One end of the fixed rod 9 is provided with a connecting ring 10. The edge position of the lower surface of the connecting ring 10 is provided with a breathable pipe 11. The outer surface of the breathable pipe 11 is provided with a ventilation rod 12. The lower surface of the ventilation rod 12 is provided with a breathable filter screen 21.

[0025] Most of the existing drying methods use manual timing to dry the grains stored in the granary. This method is time-consuming and laborious, increasing the work burden of the operators. Moreover, the drying is not thorough, which may cause the grains stored in the granary to deteriorate, thus wasting the grains.

[0026] The operator first places the ventilation rod 12 in the middle position of the granary, places the baffle plate 15 against the right inner wall of the granary, then injects the grains into the granary. Then the operator starts the hot air blower 3, and then starts the motor 7. When the hot air blower 3 works, it will send hot air into the L-shaped ventilation pipe 2. There is a ventilation opening 20 inside the arc ring 1, and there is a large gap between the connecting ring 10 and the fixed circular plate 6. The hot air will be blown into the granary along with the air flow. When the motor 7 starts, it will drive the movable rotating rod 8 and the ventilation rod 12 to rotate together, which can stir the grains stored in the granary, so as to evenly dehumidify the grains. While stirring the grains, the hot air flows along with the air flow. The two are combined and used at the same time, so as to remove the moisture on the surface of the grains and reduce the work burden of the operator.

[0027] Example 2

[0028] Improved on the basis of Embodiment 1: A hot air and microwave granary drying device. A connecting plate 13 is fixedly connected to the middle position of the outer surface of the right arc-shaped ring 1. A hollow circular block 14 is arranged on the right side of the connecting plate 13. A blocking plate 15 is arranged on the lower surface of the hollow circular block 14. An L-shaped hollow plate 16 is arranged on the right side of the hollow circular block 14. A microwave dryer 17 is arranged at the middle position on the right side of the L-shaped hollow plate 16. A support plate 18 is arranged on the lower surface of the microwave dryer 17. A fixing frame 19 is arranged on the lower surface of the support plate 18. A heat insulation layer 24 is arranged at the middle position of the inner wall of the L-shaped ventilation pipe 2. Ventilation openings 20 are arranged on the inner wall of the heat insulation layer 24. A support frame 22 is arranged on the lower surface of the hot air blower 3. A placement table 23 is arranged on the lower surface of the support frame 22.

[0029] Most of the existing drying methods are single in drying method and difficult to perform multiple drying on the grains stored in the granary. Moreover, in the rainy season, the humidity in the air is too high, which is an extremely troublesome operation for drying the grains stored in the granary. And it is difficult to directly dry the grains inside the granary, which is very likely to cause damage to the grains.

[0030] When an operator dries the grains stored in the granary, the blocking plate 15 and the ventilation rod 12 are placed inside the granary, and then the microwave dryer 17 is started. The microwaves emitted by the microwave dryer 17 will enter the granary through the L-shaped hollow plate 16 and the hollow circular block 14. The motor 7 rotates to drive the ventilation rod 12 to rotate, stirring the grains. The microwaves can quickly vibrate the water molecules inside the grains to generate heat, quickly removing the moisture. The combination of the two is used to perform multiple drying on the grains in the granary, thus reducing the work burden of the operator. At the same time, it can also directly perform multiple drying on the grains in the granary in the rainy season, improving the drying efficiency.

[0031] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
