Description

Technical Field

[0001] This utility model relates to the technical field of grain storage devices, and in particular to a grain storage device. Background Technology

[0002] Cereals are a class of grass crops whose main harvest is seeds. They are the most important food source for humankind, providing about 60% of the world's dietary energy. To prevent cereals from becoming moldy and spoiled during storage, they are usually placed inside storage facilities.

[0003] A search revealed a Chinese patent authorization announcement number CN217905248U, which discloses a grain drying and recycling storage device. The device includes a fixed support base and a grain storage bin. The grain storage bin is fixedly connected to the upper inner side of the fixed support base. This invention utilizes a ventilation component and an exhaust fan to achieve good ventilation, facilitate installation, and prevent external animals from entering and stealing grain. A threaded plug is rotated to connect to the bin cover. In use, the handle on the upper part of the movable cover is manually operated, causing the cover to slide open and close within a limiting groove. When in use, the handle is operated to slide the cover to the right within the limiting groove, opening it for ventilation. When not in use, the cover is closed to isolate it from the outside. When the cover is open for ventilation, an insect-proof mesh is installed inside the threaded plug, preventing small animals that eat grain from entering the grain storage bin and stealing it.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned storage device: In order to prevent the grain from getting moldy during the storage process, the existing technology will regularly supply air into the storage device for ventilation. However, since the grain is piled up inside the storage device, the ventilation effect of the lower part of the grain is not ideal. In addition, the existing technology requires manual opening and closing when using ventilation components, which is not convenient to operate. Based on this, the present invention designs a grain storage device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a grain storage device to solve the problems mentioned in the background art, such as the insufficient ventilation effect and the need to manually open and close the ventilation components.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grain storage device, comprising a storage box, a fixed top plate installed on the top outer wall of the storage box, a blower installed on the top outer wall of the fixed top plate, an air vent installed on the top inner wall of the fixed top plate, and air distribution pipes installed on the bottom outer wall of the air vent. The fixed top plate is provided with air outlet slots, and protective net covers are installed on the inner top wall of the fixed top plate. Guide rods are fixedly installed inside the protective net covers, and shielding covers are slidably engaged on the guide rods.

[0007] As a preferred embodiment, an air intake hood and a heating chamber are installed on the top outer wall of the fixed top plate. An air intake pipe is installed at the top of the air intake hood and is connected to the heating chamber. The output end of the blower is also connected to the heating chamber.

[0008] As a preferred embodiment, the intake pipe is equipped with a one-way valve to prevent air backflow.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-4The grain storage device shown includes a storage box 1, in which grain is placed for storage. A fixed top plate 2 is installed on the top outer wall of the storage box 1. A blower 13 is installed on the top outer wall of the fixed top plate 2. An exhaust hood 3 is installed on the top inner wall of the fixed top plate 2. An exhaust pipe 4 is installed on the bottom outer wall of the exhaust hood 3. Air holes are provided on both the exhaust hood 3 and the exhaust pipe 4. An exhaust slot 5 is provided on the fixed top plate 2. Protective mesh covers 6 are installed on the inner wall, and the protective mesh covers 6 are installed at the air outlet 5. A guide rod 7 is fixedly installed inside the protective mesh cover 6. A shielding cover 8 is slidably engaged on the guide rod 7. The shielding cover 8 is made of plastic and is lightweight. An air inlet cover 10 and a heating box 12 are installed on the top outer wall of the fixed top plate 2. A heating element is installed inside the heating box 12 and is placed horizontally inside the heating box 12. An air inlet pipe 11 is installed at the top of the air inlet cover 10. Air pipe 11 is connected to heating chamber 12, and the output end of blower 13 is also connected to heating chamber 12. During ventilation, air is first supplied to the interior of heating chamber 12 by blower 13. The air can be heated inside heating chamber 12. Then, it enters the interior of exhaust hood 3 through air inlet pipe 11. The air enters the interior of storage box 1 through the air holes on the side wall of exhaust hood 3. Air can also enter the interior of distribution pipe 4 and then enter the interior of stacked grain through the air holes on the side wall of distribution pipe 4, thereby improving the ventilation effect. Since the air inside storage box 1 can only flow out through exhaust slot 5, the airflow can drive the cover plate 8 to move upward, allowing air to flow out from the interior of storage box 1. When blower 13 stops supplying air, cover plate 8 can be lowered to cover exhaust slot 5, which helps prevent dust from entering the interior of storage box 1. Therefore, this device can more conveniently ventilate the interior of storage box 1.

[0020] In this embodiment, as Figure 1 As shown, a one-way valve 14 is installed on the air intake pipe 11 to prevent air backflow. When the blower 13 blows air, the one-way valve 14 ensures that air can only enter the storage box 1 from the air intake pipe 11.

[0021] In this embodiment, as Figure 2 As shown, a support spring 9 is provided on the side wall of the guide rod 7. Since the cover plate 8 is made of plastic, when the blower 13 stops, the cover plate 8 descends slowly due to its own weight. Therefore, the support spring 9 applies a certain pressure to help the cover plate 8 descend. Since the support spring 9 only plays the role of assisting the cover plate 8 in descending, the elastic force of the support spring 9 is relatively small.

[0022] In this embodiment, as Figure 2As shown, a feed inlet 15 is provided on the fixed top plate 2. A sealing plate 17 for covering the feed inlet 15 is installed on the top outer wall of the fixed top plate 2. A stopper plate 16 is installed on the bottom outer wall of the sealing plate 17. Grain can be easily added into the storage box 1 through the feed inlet 15. The sealing plate 17 can be connected to the fixed top plate 2 by fixing bolts to cover the feed inlet 15. After the sealing plate 17 is installed, the stopper plate 16 will be inserted into the feed inlet 15, which helps to prevent air from overflowing from the feed inlet 15.

[0023] In this embodiment, as Figure 2 As shown, a discharge pipe 18 is installed on the bottom outer wall of the storage box 1. A limit baffle 19 is movably connected to the discharge pipe 18. By pulling the limit baffle 19 out of the discharge pipe 18, the grain inside the storage box 1 can flow out through the discharge pipe 18.

[0024] Working principle of this utility model: This utility model is a grain storage device. Grains are placed inside the storage box 1 for storage. Air is supplied to the heating box 12 by the blower 13. The air is heated inside the heating box 12 and then enters the air outlet hood 3 through the air inlet pipe 11. The air then enters the storage box 1 through the air holes on the side wall of the air outlet hood 3. At the same time, the air can also enter the air distribution pipe 4, so that the air can enter the grain pile through the air holes on the side wall of the air distribution pipe 4, thereby improving the ventilation effect. Furthermore, since the air inside the storage box 1 can only flow out through the air outlet 5, the cover plate 8 can move upward under the action of the airflow, allowing the air to flow out from the inside of the storage box 1. When the blower 13 stops supplying air, the cover plate 8 can fall down to cover the air outlet 5, thereby preventing dust from entering the inside of the storage box 1. Therefore, this device can more conveniently ventilate the inside of the storage box 1.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
