[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 5 The utility model provides a technical solution: an integrated waste asphalt conveying and screening device, including a box body 1, a feed hopper 2, a connecting box 3, a conveyor belt 4, a No. 1 sieve plate 5, a No. 2 sieve plate 6, a supporting plate 7, a conveying plate 8, a sliding plate 9, a pulley 10, a motor 11, and an eccentric wheel 12.

[0030] The box body 1 is a rectangular parallelepiped structure. A feed hopper 2 is provided on the upper surface of the box body 1. The lower end of the feed hopper 2 passes through the upper surface of the box body 1. A connecting box 3 is connected to one side surface of the box body 1. The cross section of the connecting box 3 is an inverted N-shaped structure, and both sides of the connecting box 3 are open. A conveyor belt 4 is provided on the inner surface of the connecting box 3. There are three conveyor belts 4 arranged parallel to each other on the inner surface of the connecting box 3. The three conveyor belts 4 are marked as conveyor belt 1 4, conveyor belt 2 4 and conveyor belt 3 4 from top to bottom. A pulley 10 is provided on the side surface of the sliding plate 9. The pulley 10 is provided with four , and the surface of the pulley 10 is in contact with the chute provided on the inner surface of the box body 1, and another set of pulleys 10 are rotatably provided on the two side surfaces of the conveying plate 8, and the pulleys 10 here are in contact with the chute provided on the inner surface of the connecting box 3. A driving structure is provided below the multi-stage screening structure, and the driving structure is provided with a motor 11 and an eccentric wheel 12 to realize the up and down vibration of the multi-stage screening structure. The driving structure includes a motor 11, which is fixedly mounted on the outer surface of the box body 1, and the output end of the motor 11 passes through the surface of the box body 1 and is fixedly connected to the eccentric wheel 12, and the eccentric wheel 12 is located below the supporting plate 7;

[0031] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, when using this device, start the motor 11, and the motor 11 drives the eccentric wheel 12 to rotate. The rotating eccentric wheel 12 pushes the multi-stage screening structure upward, so that the multi-stage screening structure moves upward. When the multi-stage screening structure moves upward, the pulley 10 set on the side surface of the sliding plate 9 in the multi-stage screening structure rotates and contacts the inner surface of the box body 1. At the same time, the pulleys 10 on the two side surfaces of the conveying plate 8 rotate and contact the inner surface of the connecting box 3, so that the friction force of the multi-stage screening structure sliding upward is reduced. When the multi-stage screening structure loses the thrust of the eccentric wheel 12, it slides downward under the action of gravity. Under the continuous rotation of the eccentric wheel 12, the multi-stage screening structure is vibrated up and down, and the waste asphalt to be screened and transported is put into the feed hopper 2, so that the waste asphalt enters the multi-stage screening structure from the lower end of the feed hopper 2 for screening.

[0032] A multi-stage screening structure is arranged inside the box 1. The multi-stage screening structure arranges a No. 1 sieve plate 5 and a No. 2 sieve plate 6 to move simultaneously to realize multi-stage screening of waste asphalt particles. The multi-stage screening structure includes a No. 1 sieve plate 5, a No. 2 sieve plate 6 is arranged below the No. 1 sieve plate 5, and a supporting plate 7 is arranged below the No. 2 sieve plate 6. The No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7 are fixedly connected by the same connecting rod, and a gap is left between the No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7. Circular sieve holes are respectively arranged on the surfaces of the No. 1 sieve plate 5 and the No. 2 sieve plate 6, and the sieve hole area on the surface of the No. 1 sieve plate 5 is larger than the sieve hole area on the surface of the No. 2 sieve plate 6. The No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7 are fixedly connected by the same connecting rod. The horizontal plane forms a certain angle, one side of the No. 1 sieve plate 5 is fixedly connected with a conveying plate 8, and the conveying plate 8 is horizontally arranged. The same sides of the No. 2 sieve plate 6 and the supporting plate 7 are respectively fixedly connected with the same conveying plate 8, and the conveying plates 8 respectively pass through the side surface of the box body 1, and the side surface of the box body 1 is provided with a square notch. The other sides of the No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7 are fixedly mounted on the side surface of the same sliding plate 9, the end of the conveying plate 8 connected to the No. 1 sieve plate 5 is aligned with the upper surface of the No. 1 conveyor belt 4, the end of the conveying plate 8 connected to the No. 2 sieve plate 6 is aligned with the upper surface of the No. 2 conveyor belt 4, and the end of the conveying plate 8 connected to the supporting plate 7 is aligned with the upper surface of the No. 3 conveyor belt 4;

[0033] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, when the waste asphalt falls onto the surface of the multi-stage screening structure, it first falls onto the surface of the No. 1 sieve plate 5, and the large particles are intercepted by the No. 1 sieve plate 5. The small particles pass through the sieve holes on the surface of the No. 1 sieve plate 5 and fall onto the surface of the No. 2 sieve plate 6 below. After being intercepted by the sieve holes on the surface of the No. 2 sieve plate 6, the small particles pass through the No. 2 sieve plate 6 and fall onto the surface of the supporting plate 7. The asphalt that fails to pass through stays on the surface of the No. 2 sieve plate 6, so that the waste asphalt is screened according to the particle size on the No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7. The asphalt on the surfaces of the No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7 falls from the conveying plate 8 on one side to the surfaces of the No. 1 conveyor belt 4, the No. 2 conveyor belt 4 and the No. 3 conveyor belt 4 for transportation after asphalt screening.

[0034] Working principle: When using the integrated waste asphalt conveying and screening equipment, the motor 11 is used to drive the eccentric wheel 12 to rotate. The rotation of the eccentric wheel 12 can realize the up and down vibration of the multi-stage screening structure, and the waste asphalt is put into the feed hopper 2 so that the waste asphalt falls on the surface of the multi-stage screening structure. By utilizing the different sizes of the surface sieve holes, the waste asphalt particles can be arranged according to the particle size on the surfaces of the No. 1 sieve plate 5, the No. 2 sieve plate 6 and the supporting plate 7, and the conveying plate 8 is used to fall onto the surfaces of the No. 1 conveyor belt 4, the No. 2 conveyor belt 4 and the No. 3 conveyor belt 4 for transportation after asphalt screening, thereby increasing the overall practicality.
