Description
Technical Field

[0002] Grain cooling technology has been widely used in the grain storage field both domestically and internationally, becoming one of the important technical means to achieve green grain storage. Grain cooling mainly refers to the use of grain coolers to cool and lower the temperature of grains to achieve low-temperature grain storage. It can effectively slow down the metabolism of grain particles, delay quality aging and deterioration, and maintain the color, aroma, and taste of finished grains. It is particularly suitable for the storage of rice, corn, and oilseeds. The low-temperature environment is not conducive to the growth and reproduction of pests and microorganisms, reducing losses caused by pests and microorganisms, reducing the use of chemical agents, maintaining grain hygiene, and reducing losses caused by grain respiration, pests, high temperature heating, mold, and transshipment. It significantly reduces grain storage costs and is suitable for different types of silos, such as vertical silos, shallow circular silos, and flat warehouses, as well as cooling operations for various types of grains and oilseeds.

[0029] 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.
[0030] Please see Figure 1-6This utility model provides a technical solution: a uniformly cooled grain cooler with a dispersed structure, including a protective shell 1, a feeding pipe 2, a discharging pipe 3, a support block 4, a protective baffle 5, a filter frame 6, an air inlet pipe 7, a drive motor 8, a stirring rod 9, a telescopic column 10, a transmission gear block 11, a linkage gear 12, a first sprocket 13, a second sprocket 14, a compression cam 15, a maintenance gate 16, and an installation cavity 17. The protective shell 1 has an opening on its front surface, and a maintenance gate 16 is installed on the front surface of the protective shell 1. The protective shell 1 and the maintenance gate 16 are rotatably connected. The support block 4 and the protective baffle 5 are slidably connected, and a spring connects the support block 4 and the protective baffle 5. When using this device, firstly, by rotating the maintenance gate 16, the groove of the protective shell 1 is exposed, which facilitates the cleaning and maintenance of the interior of the protective shell 1. During operation, the raw material is introduced into the protective shell 1 from the feeding pipe 2, which facilitates the filtering of the raw material by the filter frame 6. Finally, impurities are discharged through the discharging pipe 3.
[0031] A feed pipe 2 is installed through the upper surface of the protective shell 1, and a discharge pipe 3 is fixedly connected to the lower surface of the protective shell 1. A support block 4 is fixedly connected to the inner wall of the opening of the protective shell 1. A protective baffle 5 is provided on the surface of the support block 4. A filter screen frame 6 is fixedly installed between the two protective baffles 5. An air inlet pipe 7 is installed through the surface of the protective shell 1. The upper end of the protective baffle 5 is arc-shaped. The air inlet pipe 7 is distributed on the side surface of the protective shell 1. The output end of the drive motor 8 penetrates the upper surface of the protective shell 1. The output end of the drive motor 8 is connected to the agitator. The stirring rod 9 is fixedly connected, and the stirring rod 9 is rotatably connected to the protective shell 1. The stirring rod 9 is slidably connected to the telescopic column 10, and the telescopic column 10 is rotatably connected to the filter screen 6. During operation, the raw materials are cooled by blowing air through the symmetrically arranged air inlet pipes 7, which improves the uniformity of cooling. At the same time, the driving motor 8 drives the stirring rod 9 and the telescopic column 10 to rotate, which facilitates the horizontal structure on the surface of the stirring rod 9 and the telescopic column 10 to stir the raw materials, increasing the contact area between the raw materials and the air, and increasing the efficiency of raw material cooling.
[0032] A drive motor 8 is fixedly connected to the upper surface of the protective shell 1. A stirring rod 9 is provided on the top surface of the opening of the protective shell 1. A telescopic column 10 is installed at the lower end of the stirring rod 9. An installation cavity 17 is opened inside the protective shell 1. The linkage mechanism includes a transmission gear block 11, which is fixedly connected to the outer surface of the upper end of the stirring rod 9. A linkage gear 12 is installed on the inner wall of the installation cavity 17. A first sprocket 13 is fixedly connected to one end of the shaft of the linkage gear 12. A second sprocket 14 is provided on the inner wall of the installation cavity 17. A pressing cam 15 is rotatably provided on the inner wall of the cavity of the protective shell 1. When the stirring rod 9 rotates, it drives the transmission gear block 11 to rotate. The transmission gear block 11 drives the linkage gear 12 and the first sprocket 13 to rotate. This allows the first sprocket 13 to drive the second sprocket 14 and the pressing cam 15 to rotate through the transmission chain, so that the pressing cam 15 cyclically pushes the protective baffle 5 above.
[0033] A linkage mechanism is installed in the mounting cavity 17. This mechanism drives the linkage gear 12, the first sprocket 13, the second sprocket 14, and the compression cam 15 to rotate via the transmission gear block 11, thereby pushing the filter screen frame 6 to vibrate. The transmission gear block 11 is meshed with the linkage gear 12, which is rotatably connected to the mounting cavity 17. The first sprocket 13 and the second sprocket 14 are also rotatably connected to the mounting cavity 17. A transmission chain is provided between the outer surfaces of the first sprocket 13 and the second sprocket 14. The shaft of the second sprocket 14 passes through the mounting cavity 17. The surface of the protective baffle 5 is fixedly connected to the shaft of the second sprocket 14 and the shaft of the extrusion cam 15. When the protective baffle 5 slides vertically, it moves relative to the support block 4, so that the spring on the surface of the support block 4 is supported, which makes it easier for the protective baffle 5 to drive the filter screen frame 6 to vibrate vertically, thus improving the screening effect of the filter screen frame 6 on the raw materials. The arc design at the upper end of the protective baffle 5 facilitates the guidance of the raw materials. Furthermore, the sliding of the filter screen frame 6 drives the telescopic column 10 to move relative to the stirring rod 9, which makes it easier for the telescopic column 10 to rotate while moving vertically, thus improving the practicality of the device.
[0034] Working principle: When using this uniformly cooled grain cooler with a dispersed structure, the raw material is introduced into the protective shell 1 through the feed pipe 2, which facilitates the cooling of the raw material by the air inlet pipe 7. The filter frame 6 filters the raw material, and impurities are discharged and cleaned through the discharge pipe 3. The drive motor 8 drives the stirring rod 9 and the telescopic column 10 to rotate and agitate the raw material. At the same time, the stirring rod 9 drives the linkage gear 12 and the first sprocket 13 to rotate through the transmission gear block 11. This causes the first sprocket 13 to drive the second sprocket 14 and the extrusion cam 15 to rotate through the transmission chain, which facilitates the sliding of the protective baffle 5 relative to the support block 4. This causes the filter frame 6 to vibrate, thereby improving the screening effect. Finally, the maintenance gate 16 is rotated for easy cleaning and maintenance, increasing the overall practicality.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
