[0021] The bottom of the extrusion ring 10 is a wave structure, and the wave structure of the extrusion ring 10 is used for extruding the extrusion block to move the tray 9.
[0022] The combing assembly comprises a mounting frame 11, two mounting frames 11 are fixedly connected on the inner wall of the drying cylinder 1, two shunt plates 12 are slidably connected on the two mounting frames 11 respectively, the shunt plate 12 is used for dispersing raw materials, one scraper 13 is also slidably connected on the two mounting frames 11 respectively, the scraper 13 is used for scraping the raw materials in the tray 9, the bottom of the shunt plate 12 and the scraper 13 is respectively in contact with the two trays 9, and the shunt plate 12 and the scraper 13 are respectively connected with the mounting frame 11.
[0023] The bottom of the shunt plate 12 is provided with a plurality of shunt grooves, and the shunt grooves of the shunt plate 12 are used for better dispersing raw materials.
[0024] The blanking assembly comprises a contact ring 15 fixedly connected between the top portions of the two upper flow distribution plates 12 and the scraper 13, the blanking hopper 3 is slidingly connected with a sliding rod 16, the bottom of the sliding rod 16 is in contact with the contact ring 15, a tension spring 18 is connected between the sliding rod 16 and the blanking hopper 3, a sealing plate 17 is fixedly connected to the sliding rod 16, the sealing plate 17 is used for sealing the blanking hopper 3, and the sealing plate 17 is in contact with the inner wall bottom of the blanking hopper 3.
[0025] When the raw materials need to be dried, first, the staff pours the raw materials into the lower hopper 3 and starts the motor 6 and the heating wire 5 at the same time. The output shaft of the motor 6 rotates to drive the rotating rod 7 to rotate, and the rotating rod 7 rotates to drive the material tray 9 to rotate. The rotation of the material tray 9 drives the extrusion ring 10 to rotate. The extrusion block 4 will first squeeze the wavy structure of the extrusion ring 10 to make the material tray 9 move upward along the rotating rod 7, and then the material tray 9 drives the extrusion ring 10 to continue to rotate. The extrusion block 4 no longer squeezes the extrusion ring 10, so that the material tray 9 moves downward rapidly under the action of gravity, and repeats this. The extrusion block 4 will squeeze the wavy structure on the extrusion ring 10 to make the material tray 9 move up and down while rotating, thereby turning over the raw materials in the material tray 9, thereby accelerating the drying of the raw materials. The material tray 9 is moved up and down, and the diverter plate 12 and the scraper 13 are pressed against each other, and the compression spring 14 is compressed. The material tray 9 moves down and no longer squeezes the diverter plate 12 and the scraper 13 of the material tray 9. The compression spring 14 is reset to drive the diverter plate 12 and the scraper 13 to reset. Repeat this process. The material tray 9 moves up and down, and the diverter plate 12 and the scraper 13 are pressed against the material tray 9 and move back and forth. The material tray 9 rotates and the raw materials in the material tray 9 rotate. The diverter plate 12 disperses the accumulated raw materials while the raw materials rotate. The scraper 13 on the upper layer scrapes the raw materials from the upper material tray 9, and the raw materials on the upper layer fall into the material tray 9 on the lower layer. The accumulated raw materials are dispersed again by the diverter plate 12 on the lower layer, and the lower layer The scraper 13 scrapes the dried raw materials from the discharge port of the lower material tray 9, and then performs secondary drying on the raw materials.

When the material tray 9 rotates and moves up and down, the diverter plate 12 disperses the raw materials accumulated on the material tray 9, and the upper scraper 13 scrapes the upper raw materials into the lower material tray 9. The lower scraper 13 scrapes the dried raw materials and discharges them from the bottom of the drying cylinder 1, and then disperses the raw materials multiple times, making the drying of the raw materials more uniform, thereby enhancing the drying effect of the raw materials. When the upper diverter plate 12 and scraper 13 move upward, they will drive the contact ring 15 to move upward. When the contact ring 15 moves upward, it will squeeze the sliding rod 16 to move upward, and the sliding rod 16 moves upward. The movement drives the sealing plate 17 to move upward, the tension spring 18 is stretched, and the raw materials in the lower hopper 3 fall into the upper material tray 9 from the gap between the lower hopper 3 and the sealing plate 17. The upper diverter plate 12 and scraper 13 are reset, driving the contact ring 15 to reset. The contact ring 15 no longer squeezes the sliding rod 16. The tension spring 18 is reset, driving the sliding rod 16 and the sealing plate 17 to reset. The sealing plate 17 blocks the lower hopper 3 and repeats this. The upper diverter plate 12 and scraper 13 move back and forth up and down while squeezing the sliding rod 16 through the contact ring 15, thereby intermittently unloading the materials and drying the raw materials in batches, thereby making the raw materials dry more fully, thereby further improving the drying efficiency. After the drying is completed, the staff can turn off the motor 6 and the heating wire 5.
