[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: Refer to Figures 1-4 As shown: A low-temperature drying and dehumidification integrated machine for oilseeds includes a drying cylinder 2, with a discharge port 3 fixedly connected to the bottom of the drying cylinder 2. A cleaning mechanism is provided at the top of the discharge port 3. The cleaning mechanism includes a drive block 10, a connecting frame 15, and an auxiliary strip 18. The bottom of the drive block 10 is provided with an inclined surface, and a stirring shaft 11 is fixedly connected to the inner ring surface of the drive block 10. A drive wheel 14 is attached to the bottom of the drive block 10. A guide member 19 is rotatably connected to one side of the drive wheel 14, and a guide plate 20 is slidably connected to one side of the guide member 19. A collar 22 is fixedly connected to one side of the guide plate 20 and is rotatably connected to the stirring shaft 11. There are three sets of auxiliary strips 18, with two auxiliary strips 18 in each set. The three sets of auxiliary strips 18 are fixedly connected by a connecting frame 2 17. The top of the auxiliary strip 18 is fixedly connected to a connecting frame 15. The top of the connecting frame 15 is fixedly connected to the guide member 19. The bottom of the guide member 19 passes through the guide plate 20. The guide member 19 and the guide plate 20 are slidably connected. A spring is sleeved on the outside of the guide member 19. A scraper 16 is fixedly connected to one side of the auxiliary strip 18. A stirring blade 12 is slidably connected to one side of the scraper 16. The surface of the stirring blade 12 is provided with a protective coating. The stirring blade 12 is fixedly connected to the outer ring surface of the stirring shaft 11.
[0024] By connecting the drive block 10 to the stirring shaft 11, the drive block 10 can rotate synchronously when the stirring shaft 11 rotates. The inclined surface at the bottom of the drive block 10 can contact the drive wheel 14 when it rotates to different positions, thereby applying a downward force to the drive wheel 14, driving the drive wheel 14 and the guide member 19 to move downward. By connecting the guide member 19 and the auxiliary strip 18 through the connecting frame 15, multiple auxiliary strips 18 and the guide member 19 can be raised and lowered synchronously, thereby changing the position of the scraper 16 on one side of the stirring blade 12. The spring can assist the guide member 19 and the auxiliary strip 18 to move upward and reset. During the raising and lowering of the scraper 16, the side of the stirring blade 12 is cleaned, reducing the residue of seeds and debris on the side of the stirring blade 12.
[0025] Example 2: Figure 1 and Figure 2 As shown, the top of the stirring shaft 11 is fixedly connected to the output shaft of the geared motor 9, the bottom of the geared motor 9 is fixedly connected to the sealing cover 1, the bottom of the sealing cover 1 overlaps with the drying cylinder 2, the sealing cover 1 is inserted through the exhaust pipe 5, the inner ring surface of the exhaust pipe 5 is fixedly connected to the axial flow fan 21, the top of the sealing cover 1 is fixedly connected to the fixing plate 6, the fixing plate 6 is inserted through the temperature and humidity sensor 7, the outer ring surface of the drying cylinder 2 is fixedly connected to the control box 4, the control box 4 is electrically connected to the heating jacket 8, the outer ring surface of the heating jacket 8 is fixedly connected to the inner wall of the drying cylinder 2, and the heating jacket 8 is fitted with the heating tube 13.
[0026] The geared motor 9 provides power for the rotation of the stirring shaft 11. The sealing cover 1 can seal and protect the top of the drying cylinder 2. The exhaust pipe 5 can assist in the discharge of moisture inside the drying cylinder 2 and support the installation and use of the axial flow fan 21 inside the exhaust pipe 5. The axial flow fan 21 can accelerate the discharge of moisture from inside the drying cylinder 2. The heating jacket 8 can support the heating tube 13. The heating tube 13 can regulate the temperature inside the drying cylinder 2, thereby heating and drying the seeds.
[0027] The operating method and working principle of this device are as follows: First, the oilseeds to be processed are fed into the heating jacket 8 through the feed inlet on one side of the drying cylinder 2. The heating tube 13 is controlled by the control box 4 to heat the seeds inside the drying cylinder 2. The temperature and humidity sensor 7 monitors the temperature change inside the drying cylinder 2. When the temperature exceeds the preset value, the external control terminal receives a signal, and the PLC controller inside the control box 4 interrupts the operation of the heating tube 13. The axial flow fan 21 accelerates the discharge of the air containing moisture inside the drying cylinder 2, ensuring the dehumidification effect on the seeds. During seed drying, the drive block 10 is driven to rotate by the geared motor 9, and the stirring blades 12 stir the seeds. The stirring blade 12 is coated with a protective layer made of polytetrafluoroethylene. The stirring ensures that the seeds are heated evenly. As the stirring shaft 11 rotates, the drive block 10 rotates with it. The inclined surface at the bottom of the drive block 10 contacts the drive wheel 14 during rotation, applying a downward force to the drive wheel 14. This causes the guide 19 to move down along the guide plate 20. The spring is compressed, and as the guide 19 moves down, the connecting frame 15 and the connecting frame 27 drive multiple auxiliary strips 18 to move down. The auxiliary strips 18 and the scraper 16 move down synchronously, which can scrape off the seeds and debris adhering to the side wall of the stirring blade 12. After drying, the valve on the discharge port 3 is opened to discharge the seeds.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
