A functional cylinder 10 is fixedly installed on the support frame 2. The lower end of the functional cylinder 10 is fixedly connected to the cover 4 via a connecting bracket 11. The functional cylinder 10 is an electric cylinder used to drive the cover 4 to lift and lower, thereby realizing the separation and connection of the cover 4 and the bottom chamber 3. When the cover 4 is separated from the bottom chamber 3, the bottom chamber 3 is in the open state; when the cover 4 is connected to the bottom chamber 3, the bottom chamber 3 is in the closed state.
[0025] The aforementioned drying fan 6 includes a fan and a heating wire. The fan generates airflow, and the heating wire, when energized, heats the airflow generated by the fan to produce hot air. The chamber cover 4 is equipped with an inlet pipe 41 and an exhaust pipe 42. The drying fan 6 is fixedly connected to the support frame 2. The outlet of the drying fan 6 is connected to the inlet pipe 41 of the chamber cover 4 via a flexible hose 61. The flexible hose 61 and the inlet pipe 41 guide the hot air generated by the drying fan 6 into the interior of the drying chamber.
[0026] The bottom box 3 is internally equipped with a limiting bearing 12, which is used to mount the material tray 9, and the material tray 9 is used to hold pellet feed. (Reference) Figure 5 The material tray 9 is annular, and the limiting shaft seat 12 is provided with a spline. The middle part of the material tray 9 is provided with a plug hole for plugging into the spline of the limiting shaft seat 12. During drying, the material tray 9 can be plugged into the limiting shaft seat 12. After drying, the material tray 9 can be removed from the limiting shaft seat 12 to realize the feeding of feed.
[0027] The box cover 4 is provided with a rotating body 7 coaxially arranged with the material tray 9. The rotating body 7 is rotatably suspended on the box cover 4 via the connecting shaft 13. The top of the box cover 4 is provided with a motor 5. The output shaft of the motor 5 is fixedly connected to the connecting shaft 13. The motor 5 can drive the connecting shaft 13 and the rotating body 7 to rotate.
[0028] Further reference Figure 2 and Figure 3 The aforementioned rotating body 7 has a first functional platform 71 extending radially into the material tray 9. An air outlet 712 is located on the side of the first functional platform 71 opposite to the material tray 9, and the air outlet 712 is connected to the air inlet pipe 41. The air outlet 712 can discharge hot air to dry the feed inside the material tray 9. The first functional platform 71 can rotate with the rotating body 7, and the air outlet 712 can rotate above the material tray 9, achieving uniform heating and drying of the feed inside the material tray 9.
[0029] refer to Figure 2 The aforementioned air inlet pipe 41 is fixedly connected to the cover 4. A sealing sleeve 14 is fixedly connected to the end of the air inlet pipe 41. The sealing sleeve 14 is rotatably and sealingly fitted onto the outside of the connecting shaft 13. The inside of the sealing sleeve 14 is connected to the air inlet pipe 41. A first air guide chamber 131 is provided inside the connecting shaft 13. An air guide hole 132 is provided on the part of the connecting shaft 13 located inside the sealing sleeve 14. The first air guide chamber 131 is connected to the air inlet pipe 41 through the air guide hole 132 and the sealing sleeve 14. A second air guide chamber 711 is provided inside the rotating body 7. The first air guide chamber 131 is connected to the air outlet 712 through the second air guide chamber 711, so that hot air enters the air outlet 712 from the air inlet pipe 41 and is discharged from the air outlet 712.
[0030] refer to Figure 3 The rotating body 7 is also provided with a second functional platform 72, which is symmetrically arranged with the first functional platform 71. The second functional platform 72 is provided with a uniform feeding device, which includes a uniform feeding plate 721 for uniformly distributing the feed inside the material tray 9 and a prying block 722 for moving the feed inside the material tray 9.
[0031] The aforementioned material leveling plate 721 is fixedly connected to the lower end of the second functional table 72. When the second functional table 72 rotates with the rotating body 7, the material leveling plate 721 is used to level the feed inside the material tray 9, so as to achieve uniform distribution of the feed inside the material tray 9.
[0032] The aforementioned lever 722 is slidably connected to the second functional platform 72 in the radial direction of the rotating body 7. Specifically, refer to... Figure 3 and Figure 4 A slider 723 is provided on the second functional platform 72. The slider 723 is slidably connected to the second functional platform 72 in the radial direction of the rotating body 7. The upper end of the lever 722 is connected to the slider 723 via a connecting rod 724. An elastic body 725 is provided between one end of the slider 723 and the second functional platform 72, and the other end of the slider 723 is fixedly connected to a guide wheel 727 via a guide rod 726. A guide ring 8 is provided on the inner wall of the cover 4, coaxially with the rotating body 7. The inner wall of the guide ring 8 is provided with annular wavy guide lines. The elastic body 725 is a spring with an extension tendency. The elastic body 725 pushes the slider 723, causing the guide wheel 727 to contact the wavy guide lines on the inner wall of the guide ring 8.
[0033] The lower part of the aforementioned pry block 722 is provided with multiple pry teeth, which can be inserted into the feed inside the material tray 9 and agitate the feed. When the second functional platform 72 rotates with the rotating body 7, the pry block 722 is used to agitate the feed inside the material tray 9. The guide wheel 727 moves along the wavy guide line of the inner wall of the guide ring 8, so that the slider 723 and the pry block 722 reciprocate in the radial direction of the rotating body 7. The pry block 722 can agitate the feed inside the material tray 9 over a larger area, which promotes uniform heating of the feed inside the material tray 9.
[0034] This rotary feed dryer includes the following working processes:
[0035] Functional cylinder 10 drives the cover 4 to rise, separating the cover 4 from the bottom box 3, opening the bottom box 3. The material tray 9 is then removed from the bottom box 3, feed is placed into the material tray 9, and the material tray 9 is placed inside the bottom box 3, completing the feed loading. Functional cylinder 10 drives the cover 4 to fall, closing the cover 4 and the bottom box 3. Hot air generated by the drying fan 6 passes through the hose 61, air inlet pipe 41, sealing sleeve 14, first air guide chamber 131, and second air guide chamber 711, exiting from the air outlet 712 to heat and dry the feed inside the material tray 9. The generated moisture is discharged from the exhaust pipe 42.
[0036] Motor 5 drives connecting shaft 13 and rotating body 7 to rotate. First functional platform 71 and second functional platform 72 follow rotating body 7. Air outlet 712 can rotate above material tray 9 to achieve uniform heating and drying of feed inside material tray 9. Equalizing plate 721 smooths the feed inside material tray 9 to achieve uniform distribution of feed inside material tray 9. Guide wheel 727 moves along the wavy guide line of guide ring 8, causing slider 723 and paddle 722 to reciprocate in the radial direction of rotating body 7. Paddle 722 moves the feed inside material tray 9 to promote uniform heating of feed inside material tray 9.
[0037] After the feed is dried, the motor 5 and the drying fan 6 stop working, the functional cylinder 10 drives the box cover 4 to rise, the box cover 4 separates from the bottom box 3, the bottom box 3 opens, and the material tray 9 is taken out from the bottom box 3, completing the feed feeding.
