When driving inclined plate 632 to rotate, when the inclined surface contacts and pushes the material, it is subjected to an upward oblique force, causing lifting tube 631 to rise. When the bottom of inclined plate 632 is finally driven to be located at the top of the material, lifting tube 631 remains stable. When the material is lowered, split transmission structure 63 is lowered by its own gravity. When lifting tube 631 is at the top and the bottom, it cooperates with lower driving structure 64 and upper driving structure 62 respectively to drive As it rotates, the dividing frame 642 of the lower driving structure 64 cooperates with the dividing structure 4 to separate different granular materials, and the stirring plate 643 rotates in the discharge box 51 to push the material to rotate.

The main driving shaft 614 cooperates with the spline platform 6312 through the spline groove 615 to drive the lifting tube 631 to rotate. At the same time, the slide tube 6311 can rotate on the main driving shaft 614, and the driving inclined plate 632 drives the lifting tube 631 to move up and down due to the material resistance and its own gravity. After the lifting tube 631 rises to a certain distance, the ring gear 3 6314 is meshed with the ring gear 4 6411, and the lifting tube 631 drives the transmission tube 2 641 to rotate, driving the material distribution frame 642 and the stirring plate 643 to rotate. After the lifting tube 631 drops to a certain distance, the ring gear 2 6313 is meshed with the ring gear 1 622, and the lifting tube 631 drives the transmission tube 1 621 to rotate, driving the driving platform 623 to rotate.

When the baffle 421 moves, the overlapping area of ​​the baffle 421 and the discharge hole 411 is adjusted, so as to adjust the discharge gap of the discharge hole 411. When screening materials, when the material distribution rack 642 rotates, the pusher 6421 rotates on the material distribution plate 41 The material on the top of the dividing plate 41 moves upward, moves to the angle plate 6422, and moves upward along the gap between the angle plates 6422. Small particles pass through the gap. When the angle plate 6422 moves, a cavity is formed on the rear side.

After a certain period of time, the main driving structure 61 drives the upper driving structure 62 to continue to add material until the main driving structure 61 drives the lower driving structure 64 to rotate. At this time, the upper driving structure 62 stops rotating and automatically stops adding material. The lower driving structure 64 separates small particle materials and large particle materials into layers through the material dividing rack 642.

[0046] Then the material distribution structure 4 drops the small particles at the bottom into the discharge box 51, and continues to dry them at low power through the microwave generator 2 52. After the materials fall, the discharge hole 411 is blocked, and then the upper drive structure 62 and the push plate 22 are driven to continue to replenish the materials. Before the next discharge, the dried small particles are discharged from the discharge barrel 53 through the stirring plate 643, and then the discharge hole 411 is fully opened to drop the large particles into the discharge box 51 for further drying. After drying, they are discharged through the stirring plate 643. When the functional structure 6 continues to work, the feeding and discharging actions are performed alternately. By stopping the main drive structure 61 at an appropriate time, the materials are given time to dry. In another working mode, in the material distribution and drying process, the small particles can be completely dried in the box body 2 31, and then under the action of the material distribution structure 4, the small particles are immediately discharged from the discharge barrel 53 after screening, the discharge barrel 53 is closed, the discharge hole 411 is fully opened, and the large particles at the bottom are dropped into the discharge box 51 for further drying.

The main drive structure (61) includes a main drive shaft (614) driven by a motor. The split transmission structure (63) includes a lifting tube (631) and a driving inclined plate (632). The main drive shaft (614) drives the lifting tube (631) to rotate. The lifting tube (631) moves up and down by driving the inclined plate (632) and the material. After the material in the second box (31) is reduced, the lifting tube (631) descends and drives the upper drive structure (62) to rotate. The upper drive structure (62) includes a transmission tube 1 (621). The transmission tube 1 (621) ) is provided with a driving platform (623) for driving a push plate (22) to perform a reciprocating pushing action in a pushing groove (234). The push plate (22) pushes the material into the guide cylinder (33) and discharges it into the second box body (31). After the material in the second box body (31) increases, the lifting tube (631) rises and causes the lower driving structure (64) to rotate. The lower driving structure (64) includes a transmission tube (641). The transmission tube (641) is provided with a material distribution frame (642) and a stirring plate (643). The material distribution frame (642) rotates in the second box body (31) and cooperates with the material distribution structure (4) to achieve material distribution. The stirring plate (643) rotates in the discharge box (51) to push the material to move to the discharge cylinder (53).
