A hot gas spraying plate 17 is fixedly connected to one end of the air guide pipe 16, and the position of the hot gas spraying plate 17 extends to the right inner wall of the screening shell 14. One end of the hot gas recovery pipe 18 is fixedly connected to the left side surface of the screening shell 14, and one end of the hot gas recovery pipe 18 is fixedly connected to the receiving end of the high-temperature heater 15. At the same time, The hot air recovery pipe 18 is used to absorb hot air inside the screening shell 14, so that the hot air inside the right side of the screening shell 14 is diverted to the left side. The flow of air is used to blow the pellets sliding down the screening guide track 110. On the one hand, the sliding speed of the pellets is reduced. On the other hand, when the hot air flows, it will take away the water vapor inside the seed coating agent and continuously dry the subsequent rolling pellets. The two side surfaces of the screening guide track 110 are fixedly connected to the two side inner wall surfaces of the screening shell 14. As the pellets fall into the screening shell 14, the blanking sleeve 124 is used to blow the pellets from different channels. The pellets are guided into different channels inside the screening guide track 110. When the pellets slide on the inner surface of the screening guide track 110, the pellets are screened and the smaller pellets are filtered out. A closed sealing plate 111 is fixedly connected to the right surface of the screening shell 14, and a double-layer guide channel 19 is fixedly connected to the outer surface of the closed sealing plate 111. The absorbed hot air is re-guided into the interior of the high-temperature heater 15 for secondary heating, so that the hot air inside the screening shell 14 is always in a high-temperature environment. The dried pellets are guided into the interior of the double-layer guide channel 19 for storage.
[0026] like Figures 1 to 5As shown, the top surface of the support frame 11 is fixedly connected to the two side surfaces of the pellet differentiation and screening shell 12, and cooperates with the pellet seed maker 13 to wrap the seeds and seed coating agent on the surface of the seeds, and discharge them into the interior of the pellet differentiation and screening shell 12. The two side surfaces of the partition plate 122 are fixedly connected to the inner wall surface of the pellet differentiation and screening shell 12, and the outer side surface of the triangular differentiation plate 121 is fixedly connected to the outer side surface of the partition plate 122, and cooperates with the partition plate 122 to perform preliminary differentiation on the fallen pellets to reduce the fallen pellets from solidifying together. The two side bottom surfaces of the triangular differentiation plate 121 and the pellet differentiation A guide groove is arranged between the inner walls of the pellet differentiation and screening shell 12. Together with the small guide groove between the triangular differentiation plate 121 and the inner walls of the pellet differentiation and screening shell 12, the deformation of the pellets due to impact during transportation can be effectively reduced. When rolling, the shape of the pellets can also be shaped. An arc guide groove 123 is arranged on the inner surface of the bottom of the pellet differentiation and screening shell 12.

[0027] Working principle: The seeds and seed coating agents are wrapped on the surface of the seeds in cooperation with the pellet seed maker 13, and discharged into the interior of the pellet differentiation and screening shell 12, and the fallen pellets are initially differentiated in cooperation with the partition plate 122 to reduce the chances of the fallen pellets solidifying together, and then differentiated to both sides by the triangular differentiation plate 121, and the differentiated pellets are guided by the arc-shaped guide groove 123, and the fine guide groove between the triangular differentiation plate 121 and the inner wall of the pellet differentiation and screening shell 12 can effectively reduce the deformation of the pellets due to impact during transportation, and can also shape the shape of the pellets during rolling.
[0028] As the pellets fall into the screening shell 14, the blanking sleeve 124 guides the pellets in different channels into different channels of the screening guide track 110. When the pellets slide on the inner surface of the screening guide track 110, the pellets are screened and the smaller pellets are filtered out. At the same time, the high-temperature heater 15 infuses the inside of the air guide pipe 16 with high-temperature heated gas, and the hot gas spraying plate 17 heats and dries the pellets when they flow inside the screening guide track 110. At the same time, the hot gas recovery pipe 18 absorbs the pellets in the screening shell 14. The hot air is collected and directed to the left side of the screening shell 14. The pellets sliding down the screening guide track 110 are blown by the airflow. On the one hand, the sliding speed of the pellets is reduced. On the other hand, the hot air will take away the water vapor inside the seed coating agent when it flows, and continuously dry the subsequent rolling pellets. The absorbed hot air is re-directed into the high-temperature heater 15 for secondary heating, so that the hot air inside the screening shell 14 is always in a high-temperature environment. The dried pellets are directed into the double-layer guide channel 19 for storage.
