[0019] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0020] Embodiment 1

[0021] Reference Figure 1-Figure 4A spiral feeder with screening function includes a pushing frame 1, a storage bin 2 is welded on the inner side of the pushing frame 1, a feeding bin 3 is welded on the top of the storage bin 2, a guide bucket 4 is welded on the inner side of the top of the feeding bin 3, in order to ensure that the screened raw materials can be concentrated in the middle of the top of the screening mechanism, sliding rails 5 are welded on both ends of the outer side of the feeding bin 3, roller slide bars 7 are slidably embedded on both ends of the inner sides of the two sliding rails 5, and a screen plate 8 is welded in the middle of the four roller slide bars 7. In order to screen the materials to be transmitted, the discharging end of the guide bucket 4 extends to the middle of the top of the screen plate 8, a slide groove 6 is penetrated on the outer side of one end of the feeding bin 3, and an annular tooth 9 is slidably embedded in the inner side of the slide groove 6 on the outer side of one end of the feeding bin 3. A half-moon tooth 10 is meshed with the inner side of the annular tooth 9, and a screening motor 11 is installed on the outer side of one end of the feeding bin 3 through the base. In order to provide the screening mechanism with the power for cyclic screening, the transmission end of the screening motor 11 is connected to the outer surface of one end of the half-moon tooth 10, and one end of the annular tooth 9 is welded to the outer surface of one end of the screen plate 8 through the slide groove 6. A conveying motor 12 is installed on the outer side of one end of the storage bin 2 through the base, and the power input ends of the screening motor 11 and the conveying motor 12 are connected to the power output end of the external control terminal. A conveying pipe 13 is welded to the outer side of the other end of the storage bin 2, and the transmission end of the conveying motor 12 is connected to the screw 14 on the inner side of the conveying pipe 13, and a discharge pipe 15 is welded to the bottom of the discharge end of the conveying pipe 13.

[0022] Working principle: First, the operator pours the raw materials to be transported into the feed bin 3. During this period, the guide bucket 4 welded on the top of the inner side of the feed bin 3 can guide the raw materials to the middle of the top of the screen plate 8. Then the operator starts the screening motor 11. At that time, the screening motor 11 will drive the half-moon gear 10 connected to its transmission end to rotate, and the half-moon gear 10 will drive the ring gear 9 meshing with it to move back and forth, and the ring gear 9 will drive the screen plate 8 welded with it to slide inside the sliding rail 5. During this period, the four roller slide bars 7 welded at the four corners of the screen plate 8 can reduce the friction of the screen plate 8 when it slides, and can also reduce the noise of the screen plate 8 when it slides. The sliding screen plate 8 can screen the raw materials accumulated on its top surface;

[0023] At that time, the cleaned raw materials will pass through the screen plate 8 and enter the storage bin 2 welded at the bottom of the supply bin 3. Then the operator will start the conveying motor 12. At that time, the conveying motor 12 will drive the screw 14 connected to its transmission end to rotate, and the rotating screw 14 will drive the raw materials in the storage bin 2 to move in the conveying pipe 13, and finally be sent out of the storage bin 2 through the discharge pipe 15 welded at the bottom of the discharge end of the conveying pipe 13, thereby realizing the raw material screening effect during the conveying period. After all the raw materials are conveyed, the bolts fixing the sliding rail 5 can be unscrewed and the screen plate 8 can be taken out for cleaning. This can ensure that the screen plate 8 will not affect the next operation. This design can make the conveying efficiency of the elevator higher.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
