DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , an embodiment provided by the present invention: a feeding and sorting device, including a screening and sorting device 1 and an elastic base device 2. The elastic base device 2 is arranged at the bottom end of the screening and sorting device 1. The screening and sorting device 1 includes a support fixing frame 3, a first sieve frame 4, a second sieve frame 5, a third sieve frame 6, a bottom plate 7, sliding holes 8, a first discharge plate 9, a second discharge plate 10, a third discharge plate 11, and sieve rods 12. The first sieve frame 4 is fixedly installed inside the support fixing frame 3. The second sieve frame 5 is fixedly installed inside the support fixing frame 3. The third sieve frame 6 is fixedly installed inside the support fixing frame 3. And the first sieve frame 4, the second sieve frame 5, and the third sieve frame 6 are all inclined. The bottom plate 7 is symmetrically and fixedly connected to the bottom end of the support fixing frame 3. The sliding holes 8 are uniformly and penetratingly opened on the bottom plate 7. The first discharge plate 9 is fixedly connected to the downwardly inclined end of the first sieve frame 4. The second discharge plate 10 is fixedly connected to the downwardly inclined end of the second sieve frame 5. The third discharge plate 11 is fixedly connected to the downwardly inclined end of the third sieve frame 6. The sieve rods 12 are uniformly and fixedly connected to the inside of the first sieve frame 4, the second sieve frame 5, and the third sieve frame 6.

[0020] The elastic base device 2 includes a fixed base 13, sliding rods 15, springs 16, and connecting rods 17. The fixed bases 13 are symmetrically arranged. The three connecting rods 17 are evenly distributed between the two fixed bases 13. And the two ends of the connecting rod 17 are respectively fixedly connected to the inside of the two fixed bases 13. The sliding rods 15 are uniformly and fixedly connected to the top end of the fixed base 13. The springs 16 are nested on the outside of the sliding rods 15.

[0021] The sliding holes 8 and the sliding rods 15 are correspondingly arranged. And the sliding rods 15 are slidably connected to the inside of the sliding holes 8. The top end of the spring 16 is closely attached to the bottom end of the bottom plate 7. When the support fixing frame 3 moves up and down, it drives the bottom plate 7 to slide on the sliding rods 15 through the sliding holes 8 and squeeze the springs 16 to contract. Since the material does not continuously press down on the first sieve frame 4 when being poured, the springs 16 immediately rebound after contraction. The rebound of the springs 16 pushes the bottom plate 7 to move upward, thereby realizing the repeated up and down movement of the support fixing frame 3.

[0022] Fixing holes 18 are penetratingly opened at both ends of the fixed base 13. And lifting frames 14 are symmetrically and fixedly installed at the positions of the two ends of the fixed base 13 inside the fixing holes 18. The fixed base 13 is fixed to the ground through the fixing holes 18 to prevent excessive shaking and tipping over.

[0023] Both ends of the bottom plate 7 are provided with plugs.

[0024] The spacing of the sieve rods 12 inside the first sieve frame 4, the second sieve frame 5 and the third sieve frame 6 is set to decrease successively, so as to achieve hierarchical screening and sorting effect. And the sieve rods 12 are designed in a curved shape, so that the material generates offset and rotation when rolling downward, thereby accelerating the rolling of the material and reducing material accumulation. The lengths of the first discharge plate 9, the second discharge plate 10 and the third discharge plate 11 are set to decrease successively, which is convenient for placing collection boxes to collect materials of different sizes.

[0025] The lifting frame 14 is located inside the plug on the bottom plate 7, and the bottom plate 7 is slidably connected inside the lifting frame 14. When moving the device, the screening and sorting device 1 and the elastic base device 2 can be moved simultaneously through the lifting frame 14 without disassembly.

[0026] Working principle: During the use process, first place the collection boxes at the middle of the bottom end of the support fixing frame 3 and the bottom ends of the outlets of the first discharge plate 9, the second discharge plate 10 and the third discharge plate 11 respectively. Then, put the material onto the upper part of the first sieve frame 4 by external force. When the material contacts the first sieve frame 4 under the action of gravity, it presses down the first sieve frame 4. The downward movement of the first sieve frame 4 drives the support fixing frame 3 to move downward. The movement of the support fixing frame 3 drives the bottom plate 7 to slide downward on the sliding rod 15 and compresses the spring 16 to contract. Since the material does not continuously press down the first sieve frame 4 when being poured, the spring 16 immediately rebounds after contraction. The rebound of the spring 16 pushes the bottom plate 7 to move upward. The movement of the bottom plate 7 indirectly drives the first sieve frame 4, the second sieve frame 5 and the third sieve frame 6 to move upward. The material is continuously put into the first sieve frame 4, so as to realize the continuous up and down shaking of the support fixing frame 3. The shaking of the support fixing frame 3 drives the first sieve frame 4, the second sieve frame 5 and the third sieve frame 6 to shake continuously, thereby accelerating the downward rolling of the material on the sieve rods 12. Due to the curved design of the sieve rods 12, the material generates offset and rotation when rolling downward, thereby accelerating the rolling of the material again and reducing material accumulation.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
