[0030] In the embodiment, as shown in Figure 1 , Figure 3 and Figure 4 , the left side of the feeding shell 3 is an open structure, after the positioning screw 9 is tightened, one end of the positioning screw 9 will be tightly attached to the bottom outer wall of the adjusting block 8, the opening on the left side of the feeding shell 3 facilitates the second feeding roller 7 to drive the adjusting block 8 to rotate synchronously, avoiding conflicts, and after the positioning screw 9 is tightened, the leftward and rightward movement of the adjusting block 8 can be limited.

[0031] In the embodiment, as shown in Figures 1-5 , two cylindrical cavities with equal sizes are arranged on the inside of the feeding shell 3, the first feeding roller 6 and the second feeding roller 7 are respectively arranged in the two cylindrical cavities and tightly attached to the inner wall of the cylindrical cavities, so that the first feeding roller 6 and the second feeding roller 7 can stably rotate on the inside of the feeding shell 3.

[0032] In the embodiment, as shown in Figure 3 and Figure 4As shown, the bottom surface of the guide hopper 2 is a symmetrical inclined surface with the middle lower and the two sides higher, and a rectangular opening is arranged at the middle position of the bottom of the guide hopper 2, which is in communication with the inner side of the mixer shell 1. When the first feeding roller 6 and the second feeding roller 7 rotate, the new and old asphalt in the long slot opening on the outer side of the first feeding roller 6 and the second feeding roller 7 will fall into the guide hopper 2 through the rectangular opening at the bottom of the cylindrical cavity in the inner side of the feeding shell 3, and then slide towards the middle position along the two inclined surfaces on the left and right sides of the bottom of the guide hopper 2, and finally fall into the mixer shell 1 for mixing through the rectangular opening at the middle position of the bottom of the guide hopper 2.

[0033] In this embodiment, as shown in Figure 3 , Figure 4 and Figure 6 , a long slot opening is arranged on the outer side of the first feeding roller 6 and the second feeding roller 7, and the adjusting block 8 can slide in the long slot opening on the outer side of the second feeding roller 7 and tightly abut the inner wall of the long slot opening on the outer side of the second feeding roller 7. When the first feeding roller 6 and the second feeding roller 7 rotate, the new and old asphalt in the storage box 4 can be conveyed downward into the guide hopper 2 through the long slot opening on the outer side of the first feeding roller 6 and the second feeding roller 7, and after the adjusting block 8 is pushed left and right, the capacity of the long slot opening on the outer side of the second feeding roller 7 can be adjusted, so that the new and old asphalt can be automatically proportioned during the feeding process.

[0034] In this embodiment, as shown in Figures 3-5 , a rectangular opening is arranged at the top and bottom of the two cylindrical cavities in the inner side of the feeding shell 3, and the size of the rectangular opening corresponds to the size of the opening part of the long slot opening on the outer side of the first feeding roller 6 and the second feeding roller 7. When the long slot opening on the outer side of the first feeding roller 6 and the second feeding roller 7 rotates to the top, the new and old asphalt in the inner side of the storage box 4 will fall into the long slot opening on the outer side of the first feeding roller 6 and the second feeding roller 7 through the rectangular opening at the top of the cylindrical cavity in the inner side of the feeding shell 3, and when the long slot opening on the outer side of the first feeding roller 6 and the second feeding roller 7 rotates to the bottom, the new and old asphalt in the long slot opening will fall into the guide hopper 2 through the rectangular opening at the bottom of the cylindrical cavity in the inner side of the feeding shell 3.

[0035] In this embodiment, as shown in Figures 1-6As shown, the top end of the positioning screw 9 is wrapped with a layer of rubber, and the outer wall of the adjusting block 8 is provided with scale lines corresponding to the capacity of the long strip-shaped open slot outside the second feeding roller 7. When it is necessary to adjust the position of the adjusting block 8, the positioning screw 9 is first loosened, and then the adjusting block 8 can be pushed left and right in the long strip-shaped open slot outside the second feeding roller 7. In this process, the capacity of the long strip-shaped open slot outside the second feeding roller 7 can be adjusted, and the capacity can be determined through the scale lines on the outer wall of the adjusting block 8. After the adjustment is completed, the positioning screw 9 is tightened again so that the top end is in close contact with the outer wall of the adjusting block 8. At this time, the rubber wrapped around the top end of the positioning screw 9 will be in contact with the adjusting block 8, thereby limiting the left and right movement of the adjusting block 8.

[0036] The working principle of the embodiment is as follows: when it is necessary to use the device to mix reclaimed asphalt materials, the old asphalt can be placed in the left storage box 4, and the new asphalt can be placed in the right storage box 4. Then, the position of the adjusting block 8 can be adjusted according to the required proportion of new and old asphalt for mixing. When adjusting, the positioning screw 9 is first loosened, and then the adjusting block 8 can be pushed left and right in the long strip-shaped open slot outside the second feeding roller 7. In this process, the capacity of the long strip-shaped open slot outside the second feeding roller 7 can be adjusted, and the capacity can be determined through the scale lines on the outer wall of the adjusting block 8. After the adjustment is completed, the positioning screw 9 is tightened again so that the top end is in close contact with the outer wall of the adjusting block 8. At this time, the rubber wrapped around the top end of the positioning screw 9 will be in contact with the adjusting block 8, thereby limiting the left and right movement of the adjusting block 8. In this way, the new and old asphalt can be automatically proportioned during the feeding process. After the adjustment is completed, the step motor 10 can be controlled to rotate slowly and uniformly. When the step motor 10 rotates, it will drive the first feeding roller 6, the second feeding roller 7, and the stirring rod 5 to rotate synchronously. When the long strip-shaped open slots outside the first feeding roller 6 and the second feeding roller 7 rotate to the top, the new and old asphalt inside the storage box 4 will fall into the long strip-shaped open slots outside the first feeding roller 6 and the second feeding roller 7 through the rectangular opening at the top of the cylindrical cavity inside the feeding shell 3. Moreover, the rotation of the stirring rod 5 can stir the asphalt in the storage box 4, preventing the asphalt from accumulating and failing to fall. When the long strip-shaped open slots outside the first feeding roller 6 and the second feeding roller 7 rotate to the bottom, the new and old asphalt in the long strip-shaped open slots will fall into the guide hopper 2 through the rectangular opening at the bottom of the cylindrical cavity inside the feeding shell 3. Then, the new and old asphalt will slide towards the middle position along the two inclined surfaces on the left and right sides of the bottom of the guide hopper 2, and finally fall into the mixer shell 1 through the rectangular opening in the middle position of the bottom of the guide hopper 2 for mixing.
