The semicircular ring 5 is provided with a cavity. The bottom of the semicircular ring 5 is provided with multiple air outlets corresponding to the multiple grooves 12. Through the coordinated design of the drying mechanism, the driving mechanism and the circular plate 2, the pellets can be rolled, thereby facilitating the improvement of the drying effect of the pellets, and further facilitating the improvement of the processing quality. Through the coordinated design of the driving mechanism, the circular plate 2, the shell 1 and the brush 6, the purpose of automatically cleaning and collecting impurities can be achieved to prevent secondary pollution caused by impurities.

[0028] In this embodiment, a fan 3 is fixedly installed on the shell 1, and an air outlet end of the fan 3 is sealed with an air pipe 4. One end of the air pipe 4 passes through the shell 1 and is sealed with the semicircular ring 5. The airflow generated by the fan 3 is transported through the air pipe 4 and the semicircular ring 5 and acts on the pellets, thereby achieving drying of the pellets. A brush 6 is fixedly installed on the bottom of the semicircular ring 5. The brush 6 is in contact with the pellets to facilitate the rolling of the pellets and clean them.

[0029] In this embodiment, the driving mechanism includes a motor 7, a gear 1 8, a gear 2 9 and a round rod 10. The motor 7 is fixedly installed at the bottom of the shell 1, and the output end of the motor 7 is fixedly connected to the gear 1 8. The gear 1 8 is meshed with the gear 2 9, and the gear 2 9 is fixedly connected to the round rod 10. One end of the round rod 10 is fixedly connected to the circular plate 2, which is used to drive the circular plate 2 to rotate in the shell 1, thereby realizing the sequential transportation of the pellets, facilitating the drying mechanism to process them and clean and collect impurities.

[0030] In this embodiment, a through hole 14 is opened at the bottom of the shell 1, and the through hole 14 corresponds to one of the multiple grooves 12. The through hole 14 and the multiple grooves 12 are both adapted to the pellets and are used to discharge the pellets after drying.

[0031] In this embodiment, a discharge port 15 is provided at the bottom of the shell 1, and the discharge port corresponds to the plurality of grooves 12.

At the same time, the circular plate 2 is pushed by the multiple grooves 12. The cleaned impurities move, and when the impurities move to the position of the discharge port 15, the impurities fall into the collection box through the discharge port 15, thereby realizing the cleaning and collection of the impurities; at the same time, the gas is allowed to enter the cavity on the semicircular ring 5 through the air pipe 4 through the action of the fan 3, and is discharged through the multiple air holes at the bottom of the semicircular ring 5. Since the semicircular ring 5 corresponds to the multiple grooves 12, the gas acts on the pellets. At the same time, due to the action of the driving mechanism and the brush 6, the pellets will roll, thereby improving the drying effect of the pellets; when the pellets move to the position of the through hole 14, the pellets are discharged from the through hole 14 due to the action of gravity.

[0035] The technical progress achieved by the utility model compared with the prior art is that the cooperation of various components not only improves the drying effect of the pellets, but also realizes the cleaning and collection of impurities, and the structure is simple and the practicability is higher.
