Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, in particular to a drying device for corn seed processing. Background Art

[0002] Corn is one of the most important food crops in the world, and the quality of its seeds directly affects the efficiency and results of agricultural production. In order to ensure the stability of corn seeds during storage and prevent losses due to problems such as mold and insect pests, corn seeds usually need to be properly processed, among which drying is one of the key steps. By reducing the moisture content in the seeds, the shelf life of the seeds can be effectively extended, and the germination rate and growth potential after sowing can be guaranteed.

[0003] In actual operation, although the existing drying devices can effectively remove moisture from the seeds, after the drying process, the corn seeds often remain at a relatively high temperature. If the high-temperature seeds are directly packaged, the temperature inside the package will remain high. As the temperature gradually drops, the air inside the package will cool down, causing the moisture in it to condense. The condensation phenomenon easily causes the seeds to absorb moisture again, thereby affecting their storage quality and may even cause the seeds to become moldy or lose vitality. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a drying device for corn seed processing.

[0005] A drying device for corn seed processing includes a fixed frame, a drying cylinder, a dryer, a stirring assembly, a first discharge pipe, a first electric valve, a heat dissipation cylinder, a second discharge pipe and a second electric valve, wherein the fixed frame is connected to the drying cylinder, the outer wall of the drying cylinder is connected to the dryer and the first discharge pipe, the first electric valve is installed in the first discharge pipe, the end of the first discharge pipe away from the drying cylinder is connected to the heat dissipation cylinder, the drying cylinder and the heat dissipation cylinder are both connected to the stirring assembly, the outer wall of the heat dissipation cylinder is connected to the second discharge pipe, and the second electric valve is installed in the second discharge pipe.

[0006] Optionally, the stirring assembly includes a stirring rod and a servo motor, the servo motors are installed on the outer walls of the drying cylinder and the heat dissipation cylinder, the output shafts of the two servo motors extend into the drying cylinder and the heat dissipation cylinder respectively, and the output shafts of the two servo motors are connected to the stirring rods.

[0007] Optionally, ventilation holes are provided on the stirring blades of the stirring rod.

[0008] Optionally, a mesh cover and a fan are also included, the outer wall of the heat dissipation tube is connected with the mesh cover, and a fan is installed on one side of the fixing frame.

DETAILED DESCRIPTION

[0017] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] A drying device for corn seed processing, such as Figure 1-Figure 4As shown, it includes a fixed frame 1, a drying cylinder 2, a dryer 3, a stirring component, a first discharge pipe 6, a first electric valve 7, a heat dissipation cylinder 8, a mesh cover 9, a fan 12, a second discharge pipe 10 and a second electric valve 11. The top of the fixed frame 1 is fixedly connected to the drying cylinder 2, the right outer wall of the drying cylinder 2 is fixedly connected to the dryer 3, the bottom of the drying cylinder 2 is fixedly connected to three first discharge pipes 6, the first discharge pipes 6 are each installed with a first electric valve 7, the lower end of the first discharge pipe 6 is fixedly connected to the heat dissipation cylinder 8, the drying cylinder 2 is connected to the heat dissipation cylinder 8 through the first discharge pipe 6, the outer wall of the heat dissipation cylinder 8 is fixedly connected to the mesh cover 9, the mesh cover 9 connects the heat dissipation cylinder 8 with the outside, the size of the grid of the mesh cover 9 is smaller than that of corn seeds, a fan 12 is installed on the rear side of the fixed frame 1, the drying cylinder 2 and the heat dissipation cylinder 8 are both connected with a stirring component, the bottom of the heat dissipation cylinder 8 is fixedly connected to three second discharge pipes 10, and the second electric valve 11 is each installed in the second discharge pipe 10.

[0019] like Figure 2 and Figure 3 As shown, the stirring assembly includes a stirring rod 4 and a servo motor 5. The servo motors 5 are installed on the outer walls of the drying cylinder 2 and the heat dissipation cylinder 8. The output shafts of the two servo motors 5 are respectively extended into the drying cylinder 2 and the heat dissipation cylinder 8. The output shafts of the two servo motors 5 are fixedly connected with the stirring rod 4. The stirring blades of the stirring rod 4 are provided with ventilation holes. The ventilation holes can allow the gas to pass through the stirring blades more freely, thereby improving the heat transfer efficiency of the gas in the drying cylinder 2 and the heat dissipation cylinder 8.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a fixed frame 13, a discharge frame 14, a sieve plate 15, a collecting frame 16 and a vibrator 17. The top of the drying cylinder 2 is fixedly connected to the fixed frame 13, the fixed frame 13 is communicated with the drying cylinder 2, the top of the fixed frame 13 is fixedly connected to the discharge frame 14, the fixed frame 13 is fixedly connected to the sieve plate 15, the inner diameter of the sieve hole of the sieve plate 15 is smaller than the size of the corn seeds, the sieve plate 15 is inclined, the fixed frame 13 is slidably connected to the collecting frame 16, the connection between the fixed frame 13 and the drying cylinder 2 is located on the left side of the fixed frame 13, the left side of the sieve plate 15 is lower than the right side, the discharge frame 14 is located on the higher side of the sieve plate 15, the collecting frame 16 is located directly below the sieve plate 15, and the outer wall of the fixed frame 13 is installed with a vibrator 17.

[0021] When it is necessary to dry the corn seeds, the first electric valve 7 and the second electric valve 11 are both in the closed state, and the corn seeds are poured from the discharge frame 14 into the fixed frame 13, and the corn seeds fall on the sieve plate 15. Under the vibration of the vibrator 17, the dust and impurities on the corn seeds are vibrated and fall on the sieve plate 15, and the dust and impurities then pass through the sieve holes of the sieve plate 15 and fall into the collecting frame 16, and the corn seeds slide along the right side of the sieve plate 15 to the left side, and then fall into the drying cylinder 2, completing the feeding of the corn seeds. Screening the dust and impurities of the corn seeds can reduce dust flying, effectively improve the working environment, and significantly improve the overall purity and quality of the seeds. After using it for a period of time, the collecting frame 16 is slid out of the fixed frame 13, and the dust and impurities collected in the collecting frame 16 are removed, and then the collecting frame 16 is slid into the fixed frame 13 again. After the corn seeds fall into the drying cylinder 2, hot air is blown into the drying cylinder 2 through the dryer 3, and then the drying cylinder 2 is dried. The servo motor 5 on the drying barrel drives the stirring rod 4 to rotate, so that the corn seeds are constantly turned and mixed, ensuring that all corn seeds can be evenly exposed to the hot air, which helps to avoid local overheating or insufficient heating, so that the corn seeds can be dried more evenly. When the corn seeds are dried, the first electric valve 7 is opened, and the corn seeds fall into the heat dissipation tube 8 from the first discharge pipe 6. The first electric valve 7 is closed, and cold air is blown into the heat dissipation tube 8 through the fan 12. The mesh cover 9 can allow the cold air to enter the heat dissipation tube 8, and then the servo motor 5 on the heat dissipation tube 8 drives the stirring rod 4 to rotate, ensuring that all corn seeds can be evenly exposed to the cold air, thereby improving the cooling efficiency of the corn seeds. The temperature of the seeds can be quickly reduced by blowing cold air, avoiding the problem of water condensation and moisture absorption of the corn seeds due to natural cooling. After cooling, the second electric valve 11 is opened to allow the corn seeds in the heat dissipation tube 8 to fall out from the second discharge pipe 10, and then the corn seeds can be collected.
