[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model describes the above technical solution in detail through the following embodiments:

[0026] like Figure 1-Figure 6 As shown, the regenerated asphalt crusher of this embodiment includes a support frame 4, a first crushing mechanism 7 and a second crushing mechanism 10. A transverse plate 2 is provided in the support frame 4, and the transverse plate 2 divides the interior of the support frame 4 into a conveying chamber and a crushing chamber. The conveying chamber is provided with a conveying mechanism 8 for conveying materials. A discharge hopper 5 is provided at the bottom of the transverse plate 2. Transfer frames 1 are provided at both ends of the discharge hopper 5. The transfer frame 1 is provided with a material dialing mechanism 6 for regulating the asphalt discharge speed. A first discharge pipe 11 and a second discharge pipe 12 connected to the conveying mechanism 8 are provided at the top of the transfer frame 1. A feed hopper 3 is connected to the top of the support frame 4. Two first crushing mechanisms 7 are provided. The two first crushing mechanisms 7 are respectively arranged on the two second discharge pipes 12, and the two first crushing mechanisms 7 are both connected to the conveying mechanism 8 in a transmission manner. The second crushing mechanism 10 is arranged at the bottom end of the discharge hopper 5.

[0027] Since the bottom of the transfer frame 1 is inclined, the asphalt accumulated on the bottom wall of the transfer frame 1 will move toward the discharge port. At this time, the material-shifting mechanism 6 rotates to push the asphalt through the arc-shaped shifting bar to prevent the asphalt cut by the first crushing mechanism 7 from quickly accumulating on the two second crushing rollers 101, causing accumulation and blockage, and affecting the final extrusion and cutting quality of the asphalt by the second crushing roller 101. Before this, the asphalt can be screened by the sieve plate 83 to determine the size of the asphalt. The larger ones will be preliminarily cut by the first crushing mechanism 7 and then sent to the second crushing roller 101 for cutting. After the sieve plate 83 filters, the smaller particles will be directly transported to the second crushing roller 101 through the first unloading pipe 11 for final cutting, which improves the cutting efficiency and quality, avoids blockage and asphalt accumulation, and also reduces the processing intensity of the second crushing roller 101.

[0028] like Figure 2-Figure 3As shown, the material-moving mechanism 6 includes a first stirring roller 61 and a second stirring roller 62, and the first stirring roller 61 and the second stirring roller 62 are symmetrically arranged in the transfer frame 1. A first round rod 610 is penetrated by the center of the first stirring roller 61, and the first round rod 610 is rotatably connected to the front and rear side walls of the transfer frame 1, and a second round rod 620 is penetrated by the center of the second stirring roller 62, and the second round rod 620 is transmission-connected to the tail end of the first round rod 610. The outer side walls of the first stirring roller 61 and the second stirring roller 62 are provided with a plurality of arc-shaped stirring bars that are staggered with each other, and their main function is to slow down the moving speed and amount of the asphalt accumulated on the inner bottom wall of the transfer frame 1, reduce the amount of asphalt moving toward the discharge port, and avoid excessive asphalt accumulating on the second crushing roller 101, affecting the cutting quality of the asphalt by the second crushing roller 101.

[0029] like Figure 5 As shown, the conveying mechanism 8 includes a conveying roller 81, a guide piece 82 and a sieve plate 83. The conveying roller 81 is rotatably connected to the power output shaft of the first driving mechanism 9. The guide piece 82 is arranged at the center of the conveying roller 81. The outer wall of the conveying roller 81 is provided with guide grooves symmetrically arranged on the left and right. The cross-section of the guide piece 82 is disc-shaped. There are multiple sieve plates 83. The head ends and tail ends of the multiple sieve plates 83 are connected to the inner wall of the first unloading pipe 11. The multiple sieve plates 83 are arranged in an array. Their main function is to divert and transport the asphalt, so that the two first crushing mechanisms 7 can divert excess asphalt and then cut it, thereby reducing the cutting strength of the first crushing mechanism 7 and improving the quality of the initial cutting of large pieces of asphalt. The sieve plate 83 can filter out the asphalt that does not need to be initially processed, thereby improving the cutting efficiency.

[0030] like Figure 6 As shown, the first crushing mechanism 7 includes a first crushing roller 71, a rotating rod 72 and a first gear 73. There are two first crushing rollers 71, two rotating rods 72 and two first gears 73. The two first crushing rollers 71 are located inside the first feeding pipe 11. The rotating rod 72 runs through the center of the first crushing roller 71. The two first gears 73 are connected to one end of the rotating rod 72. The two rotating rods 72 are rotatably connected to the first feeding pipe 11. The other end of the rotating rod 72 is transmission-connected to the power output shaft of the first driving mechanism 9. A plurality of disc-shaped cutters are provided on the outer side walls of the two first crushing rollers 71. The two first gears 73 are meshingly arranged. The large pieces of asphalt screened by the screen plate 83 can be preliminarily cut and processed by the first crushing roller 71. Since the first crushing mechanism 7 is transmission-connected to the conveying mechanism 8, the conveying and cutting are carried out synchronously, which improves the processing efficiency.

[0031] like Figure 3As shown, the second crushing mechanism 10 includes a second crushing roller 101. There are two second crushing rollers 101. The two second crushing rollers 101 are both located in the lower hopper 5. The two second crushing rollers 101 conflict with each other. A rotating rod 102 is provided at the center of the second crushing roller 101. The rotating rod 102 is rotatably connected to the inner wall of the lower hopper 5. A second gear is provided at the tail end of the rotating rod 102. The two second gears are meshed. The rotating rod 102 is transmission-connected to the first round rod 610. A second driving mechanism 103 is provided at the tail end of the rotating rod 102. The second driving mechanism 103 drives the material dispensing mechanism 6 to operate synchronously with the second crushing mechanism 10, so as to reduce the moving speed and the discharge amount of the asphalt and simultaneously realize the secondary cutting and extrusion of the asphalt to improve the processing quality.

[0032] like Figure 3 As shown, both side walls of the lower hopper 5 are provided with distribution openings, and the inner bottom walls of the two distribution openings are provided with distribution plates 52 which are arranged in an inclined shape. A scraper roller 53 is rotatably provided on the inner side wall of the distribution opening, and the outer wall of the scraper roller 53 is provided with a plurality of rubber plates arranged in a circular array, and the plurality of rubber plates are fitted with the outer wall of the second crushing roller 101. A third gear is provided at the tail end of the scraper roller 53, and the third gear is meshed with the adjacent second gear. The distribution openings can divert and discharge the debris scraped by the scraper roller 53 to the two sides of the lower hopper 5, respectively, so as to facilitate the centralized collection of the debris. After the scraper roller 53 cleans the debris remaining on the second crushing roller 101, the second crushing roller 101 can better cut and extrude the asphalt, thereby ensuring the processing quality.

[0033] like Figure 3 As shown, two guide blocks 51 with trapezoidal cross-sections are provided in the discharge hopper 5. The tops of the two guide blocks 51 are inclined to guide the discharge of asphalt, so as to facilitate the second crushing roller 101 to process the asphalt.

[0034] Working principle: First, the first driving mechanism 9 is started, and the conveying mechanism 8 is driven to rotate. The guide grooves provided on the conveying rollers 81 convey the asphalt blocks to the first feeding pipe 11 and the second feeding pipe 12. When the asphalt blocks fall into the first crushing mechanism 7, the two first crushing rollers 71 perform preliminary extrusion and cutting on the materials, and the cut asphalt is accumulated in the transfer frame 1.

[0035] At this time, the second driving mechanism 103 is started to drive the material-moving mechanism 6 to rotate, and the first moving roller 61 rotates to push the accumulated asphalt through the gap of the arc-shaped moving bar to move in the direction of the second crushing roller 101. The two second crushing rollers 101 finally extrude and cut the asphalt blocks. When the scraper roller 53 rotates, the surface of the second crushing roller 101 is cleaned by the rubber sheet, and the cleaned debris falls onto the unloading plate 52, so that personnel can better collect and classify the debris.
