Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed coating machine technology, and more specifically, it relates to a seed coating machine for Isatis indigotica. Background Technology
[0002] Isatis root, also known as indigo root, is a commonly used bulk Chinese medicinal herb. It comes from the dried root of the cruciferous plant Isatis indigotica. It has the effects of clearing heat and detoxifying, cooling the blood and reducing blemishes, and relieving sore throat and pain. It also has antibacterial, antiviral, anti-endotoxin, antitumor, and immunomodulatory effects. Ensuring timely germination after sowing isatis root is a crucial step in production. Seed coating machines are commonly used to coat Isatis root seeds. After sowing, the coated seeds quickly absorb water and swell. As the embryo develops and the seedling grows, the active substances in the seed coating are slowly released and absorbed by the seedling, altering the seed's microenvironment, providing nutrients and oxygen, promoting germination, increasing germination rate, promoting seedling growth, preventing infection by pathogens and pests during the seedling stage, ensuring strong and healthy seedlings in the field, improving seedling quality, and thus increasing yield.
[0003] Existing Isatis root seed coating machines place Isatis root seeds and coating liquid inside the housing and agitate the seeds using a stirring mechanism to evenly coat them with the coating liquid. However, this method is not convenient for drying the coating liquid on the Isatis root seeds. The coated seeds still need to be placed in a special drying device for drying, which increases the number of machines, increases costs, and reduces its practicality. Utility Model Content

An air inlet pipe 7 is connected to the input end of the fan 6. A filter screen 8 is installed inside the air inlet pipe 7 to prevent external impurities from entering the housing 1. A cover 9 is installed on the top of the housing 1. A feeding pipe 10 is connected to the cover 9. A cover plate 11 is hinged to the feeding pipe 10. The cover plate 11 is locked to the feeding pipe 10 by a latch lock 39. The pipe 10 is connected to facilitate the fixed connection between the cover plate 11 and the feeding pipe 10. The cover plate 11 is provided with a through groove 12. The inside of the through groove 12 is fixedly connected to a second mesh plate 13. The air blown into the box body 1 is discharged through the through groove 12. The second mesh plate 13 prevents the Isatis tinctoria seeds from being blown out of the box body 1.

Multiple stirring plates 26 are fixedly connected to the outside of the second rotating shaft 25, and scrapers are fixedly connected to the multiple stirring plates 26 located on the same side of the second rotating shaft 25. 27. The side end of the scraper 27 contacts the inner wall of the box 1. The top end of the first rotating shaft 24 is provided with a square post 31. The bottom end of the second rotating shaft 25 is provided with a square groove 32 that mates with the square post 31. The top end of the square post 31 is provided with a threaded hole 33. The top end of the second rotating shaft 25 is provided with a slot 34 that communicates with the square groove 32. A long screw 35 is inserted into the slot 34. The bottom end of the long screw 35 is screwed into the threaded hole 33. The box 1 is provided with multiple sliding grooves 36. A connecting plate 37 is slidably arranged inside the multiple sliding grooves 36. The multiple connecting plates 37 are all fixedly connected to the first mesh plate 2. The upper side of the side end of the multiple connecting plates 37 is fixedly connected with a lifting rod 38, which facilitates the disassembly and assembly of the first mesh plate 2.
[0039] Specifically, the first mesh plate 2 is inserted into the interior of the housing 1, and multiple connecting plates 37 are respectively inserted into multiple sliding grooves 36 to facilitate the installation of the first mesh plate 2. The square post 31 is inserted into the square groove 32, and the second rotating shaft 25 is installed on the first rotating shaft 24. Then, the long screw 35 is inserted into the slot 34 and screwed into the threaded hole 33, firmly connecting the first rotating shaft 24 and the second rotating shaft 25 together. Finally, the housing cover 9 is installed on the housing 1, with the bottom end of the housing cover 9 contacting the top ends of the multiple connecting plates 37. The motor 23 then drives the first rotating shaft 24... The shaft 24, the second rotating shaft 25, multiple stirring plates 26 and scraper 27 rotate. The multiple stirring plates 26 stir the Isatis tinctoria seeds inside the box 1, and the scraper 27 scrapes off the Isatis tinctoria seeds on the inner wall of the box 1. When it is necessary to clean the inside of the box 1, the box cover 9 is removed and the long screw 35 is unscrewed to facilitate the removal of the second rotating shaft 25 from the first rotating shaft 24, and to facilitate the removal of the second rotating shaft 25 and the multiple stirring plates 26. The connecting plate 37 and the first mesh plate 2 are moved upward by pulling the pull rod to facilitate the removal of the first mesh plate 2, and to facilitate the cleaning of the inside of the box 1.
[0040] In summary, when using the overall equipment:
[0041] Multiple electric cylinders 20 push the sealing plate 19 upward, moving it to the upper side of the air inlet 3 and bringing its top end into contact with the bottom end of the first mesh plate 2. Then, an appropriate amount of Isatis indigotica seeds are added into the box 1 through the feeding pipe 10. A cover plate 11 is then placed over the feeding pipe 10. A motor 23 drives the first rotating shaft 24, the second rotating shaft 25, multiple stirring plates 26, and the scraper 27 to rotate. The stirring plates 26 stir the Isatis indigotica seeds inside the box 1. Simultaneously, an appropriate amount of coating liquid is conveyed to the inside of the spray pipe 14 through a coating conveying device connected to the outside of the conveying pipe 16, and then evenly sprayed onto the Isatis indigotica seeds inside the box 1 through multiple nozzles 15, coating the seeds with the coating liquid. When the coating liquid coating the Isatis indigotica seeds needs to be dried, multiple electric cylinders 20... Pull the sealing plate 19 downwards to move it below the air inlet. Then start the fan 6 to blow air into the heating box 4 and the box 1. The multiple heating rods 5 inside the heating box 4 heat the air flowing from inside the heating box 4, so that the heated air is blown onto the coated Isatis indigotica seeds. At the same time, the motor 23 drives the first rotating shaft 24, the second rotating shaft 25, multiple stirring plates 26 and scraper 27 to rotate. The multiple stirring plates 26 stir the Isatis indigotica seeds inside the box 1, so that the Isatis indigotica seeds that are stuck together are separated. The air blown into the box 1 blows the Isatis indigotica seeds up, and the coating liquid on the Isatis indigotica seeds is dried evenly. After the drying process is completed, turn off the fan 6, remove the sealing seat 18, and the coated Isatis indigotica seeds are discharged from the discharge port 17.
