[0002] During the long-term service of asphalt pavement, it is often affected by external environmental factors such as temperature, ultraviolet rays, precipitation, freeze-thaw cycles, etc., which causes the internal components of asphalt to change with the increase of service life. The light components are gradually lost, and the proportion of colloid and asphalt increases. Specifically, the penetration decreases, the softening point increases, the ductility decreases, and the asphalt ages. Ultimately, the road performance of the asphalt pavement decreases, cracks, potholes, looseness and other diseases appear, and the road surface needs to be repaired and maintained. However, the large amount of waste materials generated in this process has caused serious environmental damage and waste of resources. The recycling of waste materials can not only save road construction costs and speed up construction progress, but also effectively improve the utilization rate of renewable resources, save energy, and reduce greenhouse gas emissions.
[0003] Recycling old asphalt pavement materials requires pre-treatment such as crushing and screening, and then adding a certain proportion of new aggregate, new asphalt and regeneration agent for mixing, so that the recycled materials can once again become a recycled asphalt mixture with excellent performance.
[0004] Roller crushing is currently the main method used to crush old asphalt mixtures. Two crushing rollers are set in the crushing box, and the old materials are poured onto the crushing rollers.

[0030] Specifically, the device pre-crushes large pieces of old asphalt mixture through the old asphalt mixture pre-treatment mechanism, so that the old asphalt mixture is uniformly pre-crushed before entering the crushing box 1, effectively avoiding large pieces of old asphalt mixture entering the crushing box 1 and causing blockage, thereby improving the efficiency of the old asphalt mixture crushing treatment.
[0031] See also Figure 3 and Figure 4As shown, further, in order to realize the pretreatment of the block structure of the old asphalt mixture by the continuous reciprocating motion of the movable hammer 7, the reciprocating assembly 9 includes a frame 91, the frame 91 is respectively connected to the crushing box 1 and the shell 3, a motor 92 is fixedly connected to one side wall of the frame 91, a coaxial transmission shaft 93 is fixedly connected to the output shaft of the motor 92, the transmission shaft 93 is horizontally arranged and rotatably connected to the other side wall of the frame 91, an eccentric roller 94 is fixedly mounted on the transmission shaft 93, a push rod 95 is vertically arranged at the lower side of the eccentric roller 94, and the number of push rods is preferably set to multiple, evenly arranged at the lower side of the eccentric roller 94.

The crushed old asphalt mixture can be directly screened by the setting of the filter plate 17, so that qualified crushed materials are discharged, and unqualified ones will continue to be crushed.
[0039] See also Figure 5As shown, in order to further prevent the old asphalt mixture entering the crushing box 1 from being blocked on the upper side of the crushing assembly 18 and to ensure that the old asphalt mixture in the circular cavity can be continuously and fully crushed, the crushing assembly 18 abandons the traditional double crushing roller structure, and specifically includes a rotating shaft 181, which is rotatably connected to the two opposite side walls of the crushing box 1, and the rotating shaft 181 coincides with the axis of the circular cavity.

[0040] The implementation method of this device:
[0041] When the old asphalt mixture is crushed, the old asphalt mixture first enters from the feed port 4 of the shell 3, and the smaller pieces of old asphalt mixture that meet the crushing treatment of the crushing assembly 18 will directly enter the crushing box 1 from the gap between the fixed hammer 6 and the movable hammer 7 and be crushed by the crushing assembly 18, while the larger pieces of old asphalt mixture will be blocked between the fixed hammer 6 and the movable hammer 7. At this time, the reciprocating assembly 9 is driven, and the movement of the reciprocating assembly 9 will generate a reciprocating thrust on the movable hammer 7, so that the movable hammer 7 reciprocates toward one side of the fixed hammer 6 to hit the old asphalt mixture between the two, so that the large pieces of old asphalt mixture are initially crushed, and the crushed old asphalt mixture is then passed through the fixed hammer 6. The gap between the hammer 6 and the movable hammer 7 enters the crushing box 1 to realize the secondary crushing treatment of the crushing component 18, so that the large pieces of old asphalt mixture are pre-crushed by the old asphalt mixture pretreatment mechanism, so that the old asphalt mixture is uniformly pre-crushed before entering the crushing box 1, effectively avoiding the blockage caused by the large pieces of old asphalt mixture entering the crushing box 1, thereby improving the efficiency of the crushing treatment of the old asphalt mixture. At the same time, the device drives the crushing knife 183 through the crushing wheel 182 to perform continuous and multiple crushing effects on the old asphalt mixture entering the crushing box 1, so that the old asphalt mixture can be more fully crushed and the crushing effect is improved.
