Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 8 As shown, the present invention provides the following technical solutions:

[0035] A road asphalt concrete recycling processing system, comprising a feeding member 4, a crushing member 3, a stirring member 2 and a conveying member 1 arranged in sequence from top to bottom, wherein three cavities for accommodating new asphalt concrete, old asphalt concrete and a regenerating agent are formed inside the feeding member 4, respectively, the crushing member 3 comprises a first shell part and a crushing part rotatably connected to the inside of the first shell part, the stirring member 2 comprises a second shell part and a stirring part rotatably connected to the inside of the second shell part, the first shell part, the second shell part and the cavity are connected, the top of the conveying member 1 is open to form a conveying channel for conveying finished asphalt concrete, and the conveying member 1 comprises;

[0037] Through the above technical solution, when personnel need to process asphalt concrete, they add new asphalt concrete material, old asphalt concrete material and regeneration agent into the cavities inside the three feeding parts 4 respectively. After the new asphalt concrete material, old asphalt concrete material and regeneration agent are added, they are transported through the feeding parts 4, so that the new asphalt concrete material, old asphalt concrete material and regeneration agent are transported to the crushing part 3, and the new asphalt concrete material, old asphalt concrete material and regeneration agent are received by the first shell part, and the crushing part rotates inside the first shell part, so that the new asphalt concrete material, old asphalt concrete material and regeneration agent inside the first shell part are crushed, and the new asphalt concrete material, old asphalt concrete material and regeneration agent are crushed. After the material and the regeneration agent are crushed, the new asphalt concrete material, the old asphalt concrete material and the regeneration agent are transported to the stirring element 2 through the first shell part, and the crushed new asphalt concrete material, the old asphalt concrete material and the regeneration agent are received by the second shell part, and the new asphalt concrete material, the old asphalt concrete material and the regeneration agent are stirred by the rotation of the stirring part, so as to produce asphalt concrete, and the asphalt concrete is transported to the conveyor belt 13 through the second shell part, and the transmission roller 12 rotates to drive the conveyor belt 13 to rotate, and the asphalt concrete is received by the conveying cavity formed between the two limiting belts 14 on the conveyor belt 13, and the asphalt concrete is driven to move by the conveyor belt 13, so as to complete the regeneration process of the asphalt concrete.

[0038] In addition, in the present invention, when the conveyor belt 13 conveys the asphalt concrete finished product, in order to prevent the asphalt concrete finished product from overflowing from the conveyor belt 13, as shown in FIG. Figure 1-Figure 3 As shown, a material guide rack 16 is arranged above the conveyor belt 13, and the bottom of the material guide rack 16 is open to form a material guide slope 17, and there is a gap between the bottom of the material guide rack 16 and the top of the conveyor belt 13, and the material guide slope 17 is inclined downward from one side close to the feed end of the conveying channel to one side of the discharge end of the conveying channel.

[0039] In this embodiment, after the conveying cavity formed between the two limiting belts 14 on the conveyor belt 13 receives the asphalt concrete, the conveyor belt 13 continues to drive the asphalt concrete to move.

A road asphalt concrete recycling process, characterized in that: The steps include: S1: Add new asphalt concrete material to the corresponding material guide cover (45) on the new material shell (41), add old asphalt concrete material to the corresponding material guide cover (45) on the old material shell (42), and add regeneration agent to the corresponding material guide cover (45) on the regeneration agent shell (43), so that the new asphalt concrete material, the asphalt concrete waste material and the regeneration agent are respectively transported to the inside of the new material shell (41), the old material shell (42) and the regeneration agent shell (43); S2: The new asphalt concrete material in the new material shell (41), the old asphalt concrete material in the old material shell (42) and the regeneration agent in the regeneration agent shell (43) are transported together to the inside of the second shell (31), and the first crushing roller (32) and the second crushing roller (33) are driven by the fifth motor (34) to rotate inside the second shell (31), and the new asphalt concrete material, the old asphalt concrete material and the regeneration agent are crushed by the first crushing roller (32) and the second crushing roller (33), thereby forming asphalt concrete raw materials, and the asphalt concrete raw materials are transported to the inner cavity (26) inside the first shell (25); S3: The stirring rod (27) is driven by the third motor (28) to rotate inside the inner cavity (26) to mix the asphalt concrete raw materials. The mixed asphalt concrete raw materials are guided through the material guide pipe (24). Finally, the asphalt concrete is discharged from the discharge cover (23) so that the asphalt concrete falls onto the conveyor belt (13); S4: The asphalt concrete is blocked by the limiting belt (14) on the conveyor belt (13) to prevent the asphalt concrete from falling off on both sides of the conveyor belt (13); the transmission roller (12) is driven by the first motor (15) to rotate inside the base frame (11), thereby driving the conveyor belt (13) to rotate, and the asphalt concrete is driven to move by the conveyor belt (13); the asphalt concrete is guided by the guide slope (17) on the guide frame (16) so that the asphalt concrete does not overflow from the highest point of the limiting belt (14); and the guide frame (16) is driven by the second motor (19) to reciprocate relative to the side frame (18). When the asphalt concrete on the conveyor belt (13) is discharged from the discharge end of the conveyor belt (13), the scraper (110) scrapes the discharge end of the conveyor belt (13), thereby allowing the asphalt concrete on the conveyor belt (13) to be discharged, thereby completing the production of asphalt concrete.
