[0002] Asphalt pavements constructed earlier in my country are gradually entering the repair and maintenance phase. This process inevitably generates large quantities of waste asphalt recycling. Previously, this waste material was typically discarded, resulting in significant waste and land occupation. Existing technologies generally utilize it for recycling, conserving resources and protecting the environment while offering significant economic benefits. Waste asphalt recycling involves crushing and screening the waste asphalt before remixing it with a regenerating agent, new asphalt, and fresh aggregate in a specific proportion to create a new mixture, which is then repaved onto the road surface.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. The utility model requires crushing and screening the asphalt pavement when sorting and reusing the recycled asphalt. The motor 1, motor 3 and motor 2 are started by the external controller. At this time, the staff can intermittently put the asphalt waste into the feed barrel. The operation of motor 1 can drive the triangular plate to fit on the surface of the circular plate 1 and rotate. In the initial state, the triangular plate covers the surface of the triangular feed port. When the triangular plate rotates, it will reciprocate and intermittently close and open the triangular feed port, so that the asphalt waste put into the feed barrel can be quantitatively dropped into the square funnel through the circular feed port. The asphalt waste entering the square funnel will fall on the inner side of the crushing roller 1 and the crushing roller 2. At this time, due to the rotation of motor 3, the asphalt waste will fall into the inner side of the crushing roller 1 and the crushing roller 2. The operation drives gear one to rotate, and the rotation of gear one drives gear two to rotate. The rotation of gear one and gear two drives support rod one and support rod two to rotate, thereby driving crushing roller one and crushing roller two to rotate synchronously inward to squeeze and crush the falling asphalt waste. The asphalt waste after squeezing and crushing will fall into the square feed port through the bottom of the four-corner funnel and then be discharged into the box for screening. Through this setting, the asphalt waste put in can be quantitatively crushed and screened, avoiding the increase in crushing difficulty of the crushing equipment when too much is put in, and realizing the integration of crushing and screening. The recovered asphalt waste can be directly screened during crushing, saving the process of crushing and screening separately.

[0015] 2. In the present invention, when the crushed asphalt waste falls into the interior of the box, it will be placed on the surface of the large-hole sieve plate in advance. The operation of the motor 2 will drive the rotation of the circular plate 2, and the rotation of the circular plate 2 will drive the crossbar 2 to perform a circular motion with the center of the circular plate 2 as the center of the circle. The circular rotation of the crossbar 2 will drive the connecting rod 1 to move forward and backward, and the movement of the connecting rod 1 will drive the box to move. Since four groups of plywood 2 are connected to both sides of the bottom of the box, four concave plywood are connected to both sides of the top of the square frame, and the four groups of plywood 2 correspond to the inner sides of the four concave plywood There is a movable connection with connecting rod 2. When the cross bar 2 moves horizontally to the side of the circular plate 2 close to the box body, the connecting rod 1 pushes the box body to move back to the left to the farthest distance. At this time, multiple connecting rods 2 are tilted to the left. When the cross bar 2 moves horizontally to the bottom of the side of the circular plate 2, the connecting rod 1 pulls the box body to the right and extends. At this time, multiple connecting rods 2 are in a vertical state. When the cross bar 2 moves horizontally to the side of the circular plate 2 away from the box body, the connecting rod 1 pulls the box body to the right to the closest distance close to the circular plate 2. At this time, multiple connecting rods 2 are tilted to the right. When the second horizontal bar moves to the top of the side of the circular plate 2, the connecting rod 1 pushes the box to the left again. At this time, the multiple connecting rods 2 are in a vertical state again. In this way, the cross bar 2 rotates in a circle and pulls the connecting rod 1 back and forth, thereby driving the box to move back and forth in an inverted V-shaped motion trajectory, thereby driving the waste asphalt inside the box to shake and screen. The waste asphalt falling on the surface of the large-hole screen plate will pass through the sieve holes on the surface of the large-hole screen plate and fall onto the surface of the small-hole screen plate after screening. The waste asphalt with larger specifications will slide through one end of the large-hole screen plate to the discharge port on the upper side. The waste asphalt falling on the surface of the small-hole sieve plate will pass through the sieve holes on the surface of the small-hole sieve plate during the shaking screening and fall into the surfaces of the two triangular inclined plates and be discharged and collected through the discharge port 2. The small-sized waste asphalt remaining on the surface of the small-hole sieve plate will slide through one end of the small-hole sieve plate to the discharge port 1 located below on the other side and be discharged and collected through the discharge plate. This setting can be used to perform reciprocating shaking screening on the waste asphalt inside the box, and the sorting and screening effect is improved through the multi-stage screening setting.

[0044] Specifically: the support frame 10 provides support for the motor 3 901, and the two L-shaped support rods 8 provide support for the feeding bucket 1.

[0045] Working principle: When sorting and reusing the recycled asphalt, the asphalt pavement needs to be crushed and screened. The motor 104, motor 3 901 and motor 2 401 are started by the external controller. At this time, the staff can intermittently put the asphalt waste into the feed barrel 1. The operation of motor 104 can drive the triangular plate 102 to rotate on the surface of the circular plate 101. In the initial state, the triangular plate 102 covers the surface of the triangular feed port 103. When the triangular plate 102 rotates, it will reciprocate and intermittently close and open the triangular feed port 103, so that the asphalt waste put into the feed barrel 1 can be quantitatively dropped into the square funnel 2 through the circular feed port 202. The asphalt waste entering the square funnel 2 will fall on the inner side of the crushing roller 1 903 and the crushing roller 2 907. At this time, due to the rotation of the motor The operation of gear 3 901 drives gear 1 902 to rotate, and the rotation of gear 1 902 drives gear 2 904 to rotate. The rotation of gear 1 902 and gear 2 904 drives support rod 1 905 and support rod 2 906 to rotate, thereby driving crushing roller 1 903 and crushing roller 2 907 to rotate synchronously inward to squeeze and crush the falling asphalt waste. The asphalt waste after squeezing and crushing will fall into the square feed port 303 through the bottom of the square funnel 2 and then be discharged into the box body 301 for screening. Through this arrangement, the asphalt waste put in can be quantitatively put into crushing and screening, avoiding the increase in crushing difficulty of the crushing equipment when too much is put in, and realizing the integration of crushing and screening. The recovered asphalt waste can be directly screened when crushed, saving the process of crushing and screening separately.When the crushed asphalt waste falls into the interior of the box 301, it will be pre-placed on the surface of the large-hole sieve plate 305. The operation of the motor 2 401 will drive the rotation of the circular plate 2 402. The rotation of the circular plate 2 402 will drive the cross bar 2 409 to perform a circular motion with the center of the circular plate 2 402 as the center of the circle. The circular rotation of the cross bar 2 409 will drive the connecting rod 1 405 to move forward and backward. The movement of the connecting rod 1 405 will drive the box 301 to move. Since the two sides of the bottom of the box 301 are connected with four groups of splints 2 407, the two sides of the top of the U-shaped frame 5 are connected with four concave splints 406, and the four groups of splints 2 407 correspond to the inner side movements of the four concave splints 406. It is connected with connecting rod 2 408. When cross bar 2 409 moves horizontally to the side of circular plate 2 402 close to box body 301, connecting rod 1 405 pushes box body 301 to move to the left and back to the farthest distance. At this time, multiple connecting rods 2 408 are in a tilted state to the left. When cross bar 2 409 moves horizontally to just below the side of circular plate 2 402, connecting rod 1 405 pulls box body 301 to the right and telescopes. At this time, multiple connecting rods 2 408 are in a vertical state. When cross bar 2 409 moves horizontally to the side of circular plate 2 402 away from box body 301, connecting rod 1 405 pulls box body 301 to the right and moves to the closest distance close to circular plate 2 402. At this time, multiple connecting rods 2 408 are in a vertical state. 8 is in a state of tilting to the right. When the second crossbar 409 moves horizontally to the top of the side of the second circular plate 402, the first connecting rod 405 pushes the box body 301 to the left again. At this time, the multiple second connecting rods 408 are in a vertical state again. In this way, the second crossbar 409 rotates in a circle to pull the first connecting rod 405 back and forth, thereby driving the box body 301 to move back and forth in an inverted V-shaped motion trajectory, thereby driving the waste asphalt inside the box body 301 to shake and screen. The waste asphalt falling on the surface of the large-hole sieve plate 305 will pass through the sieve holes on the surface of the large-hole sieve plate 305 and fall onto the surface of the small-hole sieve plate 306 after screening. The waste asphalt with larger specifications will slide through one end of the large-hole sieve plate 305 The waste asphalt flows into the upper discharge port 1 304 and is discharged through the discharge plate 302 for collection. The waste asphalt that falls on the surface of the small-pore sieve plate 306 will pass through the sieve holes on the surface of the small-pore sieve plate 306 during the shaking screening, and the smaller waste asphalt will fall onto the surfaces of the two triangular inclined plates 307 and be discharged and collected through the second discharge port 308. The small-sized waste asphalt that remains on the surface of the small-pore sieve plate 306 will slide through one end of the small-pore sieve plate 306 to the lower discharge port 1 304 on the other side, and be discharged through the discharge plate 302 for collection. This arrangement allows for reciprocating shaking screening of the waste asphalt inside the box 301, and the multi-stage screening arrangement improves the sorting and screening effect.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
