[0002] At present, the flocs in asphalt production generally refer to asphalt hemp flocs, which have the advantages of improving the road surface's anti-cracking performance and improving the stability of road asphalt. The hemp fibers in asphalt hemp flocs can form a coating structure with asphalt, compact asphalt particles, and reduce asphalt sedimentation and loss, thereby improving the stability of the road surface. It can improve the quality and service life of the road surface, and also help to improve driving comfort and safety.

[0003] The existing method of adding flocs to asphalt usually involves directly pouring the flocs into a mixer filled with asphalt for stirring. Pile-up flocs are poured into the mixer, which requires the mixer to work for a long time to fully mix the flocs and asphalt, resulting in low stirring efficiency. Utility Model Content

[0004] In order to improve the mixing efficiency between flocs and asphalt, the present application provides a floc feeder for asphalt production.

Due to the influence of gravity, the flocs slide from the bottom plate 13 to the connecting pipe direction. Two dispersing shafts 2 are rotatably connected in the feeding box 1. The length directions of the two dispersing shafts 2 are the same as the inclination angle of the bottom plate 13. A plurality of dispersing blades 21 are installed on the dispersing shafts 2 along the length direction. A driving motor 22 is installed outside the feeding box 1, and the output shaft of the driving motor 22 is coaxially fixedly connected to one of the dispersing shafts 2. The ends on the same side of the two dispersing shafts 2 are coaxially fixedly connected with a transmission sprocket 23. The two transmission sprockets 23 are provided with a transmission chain 24. Start the driving motor 22, drive one of the dispersing shafts 2 to rotate, and drive the other dispersing shaft 2 to rotate through the transmission sprocket 23 and the transmission chain 24, so that the two dispersing shafts 2 rotate and stop at the same time. The flocs are fed into the feeding box 1 from the feeding port 11 of the feeding box 1, and the two breaking shafts 2 are rotated so that the breaking blades 21 break the flocs. The broken flocs are transported from the conveying pipe 12 to the mixer to be mixed with asphalt, thereby improving the mixing efficiency between the flocs and asphalt.

A rotating motor 31 is installed on the feed box 1. The output shaft of the rotating motor 31 is coaxially fixedly connected to the switching shaft 32. When it is necessary to feed flocs into the mixer, the rotating motor 31 is started, the switching shaft 32 rotates, and the plugging plate 3 rotates away from the delivery pipe 12 to open the delivery pipe 12. When it is no longer necessary to feed flocs into the mixer, the switching shaft 32 rotates, and the plugging plate 3 rotates toward the amplitude pipe to plug the entrance of the delivery pipe 12.

[0035] Reference Figure 2 , an induced draft fan 4 is installed outside the feeding box 1, and the induced draft fan 4 is connected to the feeding box 1 through a blowing pipe 41. In the process of breaking up the floccules and conveying the floccules into the conveying pipe 12, the induced draft fan 4 is started to blow air into the feeding box 1 through the blowing pipe 41, so as to improve the floc breaking efficiency, reduce the possibility of the flocs being entangled on the breaking shaft 2 and the breaking blades 21, and facilitate the conveying of the flocs from the conveying pipe 12.

A protective frame 6 is installed on the outer wall of the protective net 5. A support frame 14 located below the protective frame 6 is fixedly connected to the feeding box 1. A rotating shaft 61 is installed on one side of the protective frame 6. The rotating shaft 61 is rotatably connected to the feeding box 1. A pulling handle 62 is installed on the top of the protective frame 6 away from the rotating shaft 61.

When the protection frame 6 is located above the support frame 14, the limit block 72 is located in the limit groove 63, which improves the stability of the protection frame 6 and the protection net 5, and the pull ring 711 is moved in the direction away from the feeding box 1, and the limit block 72 is moved in the direction away from the limit groove 63. The elastic spring 73 is compressed, so that the limit block 72 is separated from the protection frame 6 and the protection net 5 is opened. In the process of rotating the protection frame 6 to the top of the support frame 14, the inclined surface 721 of the limit block 72 abuts against the side wall of the protection frame 6. In the process of rotating the protection frame 6 inwardly toward the feeding box 1, the limit block 72 moves into the accommodating groove 15, and the elastic spring 73 is compressed. When the limit groove 63 corresponds to the accommodating groove 15, the compressed elastic spring 73 pushes the limit block 72 to move in the direction of the limit groove 63, so that the limit block 72 moves into the limit groove 63.
