Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a grain storage device. Background Art

[0002] During the storage process, grain generally needs to be dried before it can be stored. Otherwise, when the grain has a high moisture content, it is easy to be damaged. However, even if the grain is dried at the time, it will still breathe during storage later. Therefore, even if the grain on the surface is in a dry state, the grain accumulated inside will still generate heat and moisture, which cannot be discharged to the outside and will be damaged after a period of time. Therefore, it is necessary to design a storage device that can dry and dehumidify the grain in the entire granary according to needs during later storage. Utility Model Content

[0022] like Figure 1-Figure 3 A grain storage device shown includes: a silo 1, a rotating shaft 6, a driving mechanism and a heating mechanism.

[0023] The inside of the silo 1 is hollow to form a storage chamber 2. The top of the silo 1 is provided with a feed port 3, and the bottom is provided with a discharge port. Both the feed port and the discharge port are connected to the storage chamber 2. A discharge pipe 4 is provided at the discharge port, and a control valve 5 is provided on the discharge pipe 4. When in use, grain is fed into the storage chamber 2 through the feed port 3 for storage, and then can be discharged outward through the discharge pipe 4. The control valve 5 is used to control the discharge pipe 4 to open or close. The control valve 5 can be a manual valve or a solenoid valve, which is not limited here.

[0024] The rotating shaft 6 is vertically arranged and rotatably installed in the silo 1. The rotating shaft 6 is provided with a plurality of blades 7 arranged alternately in the up-down direction. The rotating shaft 6 and the blades 7 are both hollow inside and interconnected. The blades 7 are provided with a plurality of ventilation holes 8. The driving mechanism is connected to the rotating shaft 6 to drive the rotating shaft 6 to rotate 360 ​​degrees around its own axis. The heating mechanism includes an air pump 9, a heating element 10 and a ventilation pipe 11. The air pump 9 is connected to the ventilation pipe 11, the heating element 10 is connected to the ventilation pipe 11, and the ventilation pipe 11 is connected to the rotating shaft 6.

[0025] Specifically, the device mainly arranges a dynamic airflow drying structure in the silo 1, which is used to dry the grain during the grain storage process, reduce the water content of the grain, and thus increase the storage time of the grain.

[0026] The dynamic airflow drying structure has two main functions. The first is to push the stored grain to flow dynamically through the rotating shaft 6 and the blades 7. Since the rotating shaft 6 can rotate under the action of the driving mechanism and a plurality of blades 7 are provided on the rotating shaft 6, when the rotating shaft 6 rotates, the blades 7 can push the grain at different heights to flow, so that the grain in the entire silo 1 can flow; the second is to allow hot air flow to be introduced for drying. Since the rotating shaft 6 and the blades 7 are both hollow structures and the blades 7 are provided with air vents 8, when working, the air pump 9 draws external air to the heating element 10 for heating. After that, the hot air flow flows to the rotating shaft 6 through the branch pipe, and then flows to different blades 7, and finally flows out from the ventilation holes to dry the grain. The dried humid air flow can be discharged through the upper feeding port 3, thereby realizing air circulation.

[0027] Since the blades 7 continue to push the grain to flow during the drying process by introducing hot air, the two actions are superimposed to quickly and evenly dry and dehumidify the grain in the entire silo 1, and the drying efficiency is relatively high.

[0028] In further settings, such as Figure 3 As shown, the silo 1 is a hollow cylindrical structure, the blade 7 is a T-shaped structure, the blade 7 includes a connecting portion 12 and a pushing portion 13, the connecting portion 12 is connected to the pushing portion 13, the pushing portion 13 is connected to the connecting portion 12, the surface of the pushing portion 13 close to the inner wall of the silo 1 is an arcuate surface, and the inner diameter of the arcuate surface is equal to the inner diameter of the inner wall of the silo 1, thereby the inner wall of the silo 1 can play a certain supporting role for the blade 7, and in addition, there are multiple blades 7, which are staggered in the up and down directions, and finally the inner wall of the silo 1 can support the entire shaft 6 and the blade 7 from different directions, so that the shaft 6 is not easy to tilt and deform.

[0029] In addition, a rounded transition is provided at the connection between the connection portion 12 and the pushing portion 13, thereby avoiding stress concentration.

[0030] like Figure 1 and Figure 2 As shown, a avoidance hole is provided at the bottom of the silo 1, and a bearing seat 14 is provided at the avoidance hole. The rotating shaft 6 is rotatably supported on the bearing seat 14, thereby realizing that the rotating shaft 6 is rotatably connected to the silo 1.

[0031] like Figure 1 and Figure 2 As shown, the driving mechanism includes a motor 15, a first gear 16 and a second gear 17. A bracket 18 is provided at the bottom of the silo 1, and the motor 15 is fixedly arranged on the bracket 18. The output shaft of the motor 15 is connected to the first gear 16, and the rotating shaft 6 is connected to the second gear 17. The first gear 16 is meshed with the second gear 17, so that the motor 15 can drive the rotating shaft 6 to rotate through the transmission of the first gear 16 and the second gear 17. This driving form is simple and easy to implement.

[0032] like Figure 2 As shown, the bottom of the rotating shaft 6 is opened to form an insertion port, and the ventilation pipe 11 is inserted into the insertion port, so that the ventilation pipe 11 will not affect the normal rotation of the rotating shaft 6, and at the same time, air flow can be introduced into the rotating shaft 6. The heating element 10 used on the ventilation pipe 11 can be a heating pipe with an electric heating wire, and the heating pipe is covered on the ventilation pipe 11, so that the air flow can be heated when it flows through the ventilation pipe 11.

[0033] In summary, the present device mainly arranges a dynamic airflow drying structure in the silo 1 for storing grain, that is, the grain in the entire silo 1 is driven to flow through the rotating shaft 6 and the blades 7, and then a hot air flow is introduced into the rotating shaft 6 and the blades 7. After the hot air flow flows out from the through holes of the blades 7, the grain in the entire silo 1 can be dried and dehumidified quickly and evenly, and the drying efficiency is relatively high. After the grain is dried, the moisture content of the grain is reduced, thereby increasing the storage time of the grain.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
