The bottom end of the first rotating shaft 14 extends through the inner ring of the bearing to the bottom of the first circular groove 13 and is connected to a first gear 12. The bottom of the first gear 12 is movably connected to the bottom of the inner cavity of the frame 8 through a rotating shaft and a bearing. Several evenly distributed material feeding plates 15 are bolted to the first rotating shaft 14 near the top and bottom. A drive motor 17 is bolted to the bottom of the frame 8 near the front. The bottom end of the rotating shaft on the bottom of the first gear 12 passes through the inner ring of the bearing and is connected to the output shaft of the drive motor 17.

[0023] In this embodiment, it is designed to rotate and guide the material effectively, thereby enabling efficient and uniform drying and improving its drying efficiency.

[0024] The second rotating shaft 21 is fitted inside the second circular groove 16, and the top and bottom of the second rotating shaft 21 are movably connected to the corresponding two sealing plates 4 by bearings. The bottom end of the second rotating shaft 21 extends through the inner ring of the bearing to the bottom of the second circular groove 16 and is fitted with a second gear 24. The spiral conveying blade 22 is fitted on the second rotating shaft 21 in the second circular groove 16. The bottom of the frame 8 is connected to the hot air blower 18 by bolts near the rear side, and the bottom end of the second rotating shaft 21 is fitted into the air outlet of the hot air blower 18 by bearings. The second rotating shaft 21 is hollow, and several evenly distributed first air jet holes 20 are opened on the second rotating shaft 21 in the second circular groove 16. The second rectangular block 11 is hollow, and several evenly distributed second air jet holes 23 connected to the hollow are opened on the inner wall of the second circular groove 16.

[0025] The top of the second rectangular block 11 is provided with rectangular grooves 5 that are connected to the guide port 19 near the front and rear sides. A baffle plate 7 is fitted inside the rectangular groove 5. An electric push rod 6 that matches the two baffle plates 7 is connected through the top of the frame 8 near the rear side. The bottom end of the electric push rod 6 is connected to the top of the baffle plate 7 by bolts. A receiving box 9 is attached to the rear side of the second rectangular block 11 near the top. The top of the receiving box 9 is open. A plug-in plate is connected to the rear side of the receiving box 9 by bolts. A plug-in groove that matches the plug-in plate is provided on the inner wall of the rear side of the frame 8.

[0026] Implementation plan: This allows for repeated multiple drying cycles, enabling continuous and thorough drying of silkworm cocoons, thus improving its utilization and work efficiency.

[0027] Working Principle: In operation, the sealing plate 4 at the top of the first circular groove 13 is first opened, and silkworm cocoons are introduced into the first circular groove 13. The sealing plate 4 is then closed. The hot air blower 18 guides hot air into the second rotating shaft 21 and ejects it through the first jet nozzle 20. The hot air is then guided into the first circular groove 13 through the guide port 19. Subsequently, the drive motor 17 drives the first gear 12 and the first rotating shaft 14 to rotate. The first rotating shaft 14 drives the feeding plate 15 to rotate. The feeding plate 15 then guides the silkworm cocoons from the lower guide port 19 into the second circular groove 16. The first gear 12 then drives the second gear 24 to rotate. The second gear 24, through the second rotating shaft 21, drives the spiral conveyor blades 22 to rotate and guide the cocoons back through the upper guide port 19. The cocoons are fed into the first circular groove 13, allowing for effective rotation and material guidance, thus enabling efficient and uniform drying and improving drying efficiency. This allows for repeated, multiple drying cycles, ensuring continuous and thorough drying of the cocoons, enhancing both usage and work efficiency. Then, the front electric push rod 6 extends, driving the front baffle plate 7 into the front rectangular groove 5. Simultaneously, the rear electric push rod 6 retracts, causing the rear baffle plate 7 to disengage from the rectangular groove 5. At this point, the second rotating shaft 21 drives the spiral conveyor blades 2 to guide the dried cocoons through the rear guide port 19 into the receiving box 9. Pulling the receiving box 9 forward causes the insertion plate to detach from the insertion slot, allowing the receiving box 9 to be easily removed for convenient material retrieval.
