Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a storage bin with a ventilation structure, including a storage tank 1. A load-bearing frame 2 is welded to the outer wall of the storage tank 1. A material receiving pedestal 3 is welded to the top of the load-bearing frame 2. The material receiving pedestal 3 is located at the bottom of the storage tank 1 and is spaced apart from it by a certain distance. A tank cover 4 is inserted and connected to the top of the storage tank 1. A feeding assembly 5 and a stirring assembly 6 are respectively arranged on the top of the tank cover 4. The tank cover 4 and the storage tank 1 are threadedly connected through a limit bolt 7. An exhaust fan 8 is arranged on one side of the storage tank 1. A temperature and humidity display 9 is arranged on the other side of the storage tank 1. A warm air blower 10 is connected to the bottom of the storage tank 1 through bolts. A part of the warm air blower 10 penetrates into the interior of the storage tank 1. A partition board 11 is welded to one end of the inner wall of the storage tank 1 adjacent to the warm air blower 10. The partition board 11 is located above the warm air blower 10. A baffle plate 12 is attached to the surface of the partition board 11. The baffle plate 12 is slidably connected to the chute on the inner wall of the storage tank 1 through a slider.

[0025] A moisture discharge port 101 is penetrated and arranged on one side of the storage tank 1. A discharge port 102 is penetrated and arranged on the other side of the storage tank 1. A discharge plate 103 is arranged on one side of the outer wall of the storage tank 1 and is attached below the discharge port 102. The discharge plate 103 is located above the material receiving pedestal 3 and is spaced apart from it by a certain distance. A driving bevel gear 104 and a driven bevel gear 105 are respectively rotatably connected to the cavity on the same side as the discharge port 102 inside the storage tank 1. The driven bevel gear 105 is vertically distributed with respect to the driving bevel gear 104 and meshes below it. A lead screw 106 is installed on the driven bevel gear 105 through a shaft rod penetrating through its axis. The lead screw 106 is connected to the protruding side of the baffle plate 12 through a nut provided on its surface and bolts.

[0026] The feeding component 5 includes a feeding tank 501 and a tank cover 502. The feeding tank 501 penetrates through the tank cover 4. One end of the tank cover 502 is rotatably connected to the feeding tank 501 through a hinge. An internal bracket 503 is provided on the inner wall of the feeding tank 501, and an inner gasket 504 is placed on the surface of the internal bracket 503.

[0027] The stirring component 6 includes a driving gear 601 and a driven gear 602. The driving gear 601 is rotatably connected to the top of the tank cover 4 through the output end of a stepping motor. The driven gear 602 meshes with one side of the driving gear 601, and a stirring member 603 is installed through a shaft rod at its axis. The stirring member 603 is located inside the storage tank 1.

[0028] In this embodiment, as Figure 1 shown, a temperature sensor and a humidity sensor electrically connected to the temperature and humidity display 9 are respectively provided inside the storage tank 1. An annular notch for plugging and connecting the tank cover 4 is provided at the top of the storage tank 1. A metal plate in a grid shape is provided on the surface of the moisture discharge port 101. At the same time, the suction fan 8 is located at one end of the moisture discharge port 101. The storage tank 1 and the tank cover 4 are first connected by plugging and then fixedly connected by a limit bolt 7. The two different connection methods increase the tightness of the connection between them, thereby helping to achieve the sealing inside the storage tank 1, providing favorable conditions for the storage of raw materials. The temperature and humidity data inside can be accurately obtained through the temperature and humidity sensors inside the storage tank 1, which is convenient for production personnel to take corresponding treatment measures in a timely manner, helps to maintain the stable conditions for storing raw materials inside the storage tank 1, and guarantees the quality of the internal raw materials. When the humidity sensor detects that the moisture inside is too heavy, the cut-off valve on the side of the pipeline of the suction fan 8 is opened, and the excess moisture inside the storage tank 1 can be discharged in a timely manner through the moisture discharge port 101. The grid-shaped through holes on the surface of the moisture discharge port 101 effectively prevent the raw materials from being sucked into the pipeline. Compared with the direct ventilation structure, this treatment method can accurately control the operation of the suction fan 8 according to the humidity feedback inside the storage tank 1, avoiding the trouble of high-humidity air re-entering the inside of the storage tank 1 due to excessive ventilation.

[0029] In this embodiment, as Figure 2As shown in the figure, the stirring members 603 are evenly distributed inside the storage tank 1 and are formed by combining a number of arc-shaped strips made of rubber in a circular distribution. The diameter of the stirring member 603 is close to the inner wall of the storage tank 1 and is spaced a certain distance from it. At the same time, the stirring member 603 forms a rotating structure inside the storage tank 1 through the driving gear 601 and the driven gear 602. The structure of the stirring member 603 can fully mix the internal raw materials inside the storage tank 1, so that when the suction fan 8 and the heater 10 are processed separately, the effect is more uniform, avoiding the phenomenon of excessive local humidity or insufficient drying. At the same time, its structural form and material can reduce mechanical damage to rapeseed during the stirring process, resulting in rupture, which helps to maintain the integrity of the raw materials.

[0030] In this embodiment, as Figure 3 shown, the tank cover 502 forms an opening and closing structure with the feeding trough 501 through a hinge. A strip-shaped notch is opened at the top of the feeding trough 501 for inserting and connecting the bottom of the tank cover 502. The outer walls of the connection between the feeding trough 501 and the tank cover 502 are respectively covered with mutually fitting outer rubber gaskets 505. At the same time, one side of the feeding trough 501 and the tank cover 502 is threadedly connected by a fixing bolt 506. The split structure of the tank cover 4 and the storage tank 1 provides convenience for cleaning the inside of the storage tank 1 after subsequent use. By adding the feeding assembly 5, there is no need to frequently open the tank cover 4 for the feeding link. The opening and closing structure of the tank cover 502 and the feeding trough 501 is convenient for the feeding of raw materials. At the same time, after the two are initially positioned to a certain extent through the insertion connection and then further fixed by the fixing bolt 506 through threading, the tightness of the fit is strengthened. At the same time, through the inner gasket 504 and the outer rubber gasket 505 in sequence for further sealing treatment, the tight fit of the connection part is further enhanced, and the gap is also reduced as much as possible, further improving the sealing performance.

[0031] In this embodiment, as Figure 4 and Figure 5 shown, the partition plate 11 is inclined. The higher side of the partition plate 11 is a solid inclined sliding surface, and the lower side of the partition plate 11 is a grid-shaped metal plate. At the same time, the baffle 12 is attached to the lower side of the partition plate 11. The grid-shaped through holes on the surface of the partition plate 11 can effectively allow the airflow generated by the heater 10 at the bottom to flow through it. Due to the characteristic that hot air rises, through the cooperation of the stirring member 603, the hot air is more evenly distributed inside and fully contacts the raw materials, thereby achieving the drying effect. At the same time, the cooperation of the structural positions of the partition plate 11, the baffle 12 and the discharge port 102 can effectively control the discharge of raw materials.

[0032] In this embodiment, as Figure 5As shown in the figure, the output end of the servo motor is installed at the axis center of the driving bevel gear 104, and the lead screw 106 forms a rotating structure through the driving bevel gear 104 and the driven bevel gear 105. Moreover, the baffle 12 forms a lifting structure between the partition 11 and the discharge port 102 through the lead screw 106. At the same time, the discharge port 102 is attached to the protruding side of the baffle 12. The lifting of the baffle 12 can accurately control the discharge and interception of the internal raw materials, and the inclined structure of the partition 11 can guide the raw materials to discharge in a specific direction under the action of gravity, fully ensuring the sufficiency of the release of the internal raw materials and reducing the possibility of internal residues.

[0033] The usage method and advantages of the present utility model: For this storage bin with a ventilation structure, during use, the working process is as follows:

[0034] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, first, when blanking is required, turn the fixing bolt 506. After removing the fixing bolt 506, the trough cover 502 can be flipped from the top of the feeding trough 501. After taking out the inner gasket 504 from the surface of the built-in bracket 503, the rapeseed raw materials to be stored can be put into the feeding trough 501. After the material is put in, the inner gasket 504 is placed on the surface of the built-in bracket 503 again, and the trough cover 502 is covered on the surface of the feeding trough 501 by flipping. Finally, the two are threadedly connected by the fixing bolt 506. During the storage process, the temperature and humidity sensor inside the storage tank 1 will monitor the internal temperature in real time and display it through the external temperature and humidity display 9 (A2000TH). When the internal humidity is too high, the alarm system of the temperature and humidity display 9 will sound. The operator starts the power supply, and the stop valve at the pipe opening on one side of the suction fan 8 is opened. It should be noted that in the prior art, electric actuators or pneumatic actuators are usually used, which are connected to the control system to receive operation instructions and feedback signals for automatic control and monitoring. After the stop valve is opened, the suction fan 8 sucks in the air with a high moisture content through the negative pressure effect and discharges it to the external environment through the discharge port. At the same time, the hot air heated by the heater 10 at the bottom forms a hot air flow. Since hot air rises, these hot air flows are pushed upward by the fan. And when the suction fan 8 and the heater 10 work simultaneously, the driving gear 601 in the stirring assembly 6 at the top of the tank cover 4 rotates driven by the stepping motor, driving the driven gear 602 to rotate, so that the stirring member 603 connected to the driven gear 602 rotates inside the storage tank 1, ensuring that the rapeseed raw materials can be evenly affected by the air of the suction fan 8 and the heater 10 during flipping in the storage tank 1, avoiding uneven treatment caused by accumulation, and significantly improving the ventilation, dehumidification and drying efficiency and quality of the rapeseed in the storage tank 1. During this process, the temperature and humidity sensor inside the storage tank 1 will monitor the internal temperature in real time and display it through the external temperature and humidity display 9. When the temperature and humidity inside the tank meet the storage requirements, the power supply is turned off. When the internal raw materials need to be extracted, the container for receiving the raw materials is placed on the receiving pedestal 3, and the power supply above the discharge port 102 is started. The driving bevel gear 104 rotates, driving the driven bevel gear 105 and the screw rod 106 coaxially connected to it to rotate. Then, the nut on the surface of the screw rod 106 drives and drives the baffle 12 to lift upward. During the upward movement of the baffle 12, the sliders on both sides slide in the chute on the inner wall of the storage tank 1 to ensure the smoothness of its operation. When the baffle 12 rises for a moment, the raw materials that lose the blockage will slide from the lowest side of the end point of the partition 11 towards the discharge port 102 and slide out through the inclined discharge plate 103.

[0035] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
