After the asphalt concrete is recycled, a part of the asphalt aggregate particles are obtained through crushing and other processes. These asphalt aggregate particles need to be filtered and screened, and then mixed with new asphalt to obtain a suitable road recycled asphalt mixture.
[0003] Because some of the asphalt concrete aggregate particles are stuck together with the soil after being washed by rainwater, the existing screening equipment cannot effectively break up the stuck aggregate particles during the asphalt concrete aggregate screening process, causing the stuck aggregate particles to clog the mesh of the screening equipment, affecting the screening and not being conducive to improving the screening effect.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.
[0024] like Figures 1 to 4 As shown, the asphalt concrete aggregate particle screening device provided by the embodiment of the utility model comprises a box body 1 and a rotating member 2, the rotating member 2 is rotatably mounted in the box body 1, the rotating member 2 comprises a motor 3, a rotating shaft 4 and a combing plate 5, the output end of the motor 3 is connected to the rotating shaft 4 through a coupling, the rotating shaft 4 is rotatably mounted in the box body 1, and the combing plate 5 is fixedly connected to the rotating shaft 4;
[0025] A first screen plate 6 is detachably installed in the box body 1, and the first screen plate 6 is arranged in an arc shape.
[0026] It should be noted that the motor is configured as a servo motor, and the motor 3 can rotate the combing plate 5 to just above the first screen plate 6. When the combing plate 5 is punching materials, the rotation angle of the output end of the motor 3 is set to ±80°.
[0027] By adopting the above scheme, through the use of the combing plate 5, after the aggregate particles are put into the box body 1 from the feed port of the box body 1, some small-sized particles leak from the first screen plate 6 to the bottom of the box body 1, and the combing plate 5 is driven to rotate in the box body 1 through the rotation of the output end of the motor 3, so that the combing plate 5 collides with the aggregates retained on the first screen plate 6, breaks up the aggregates stuck together, and removes the aggregate particles blocking the mesh of the first screen plate 6, so that the small particles of material can fall from the first screen plate 6 to the bottom of the box body 1, which can break up the aggregate particles stuck together and effectively prevent the aggregate particles stuck together from blocking the mesh of the first screen plate 6.
[0028] In this embodiment, a push plate 9 for pushing aggregate out of the box body is slidably installed on the inner wall of the box body 1, the side of the push plate 9 is in contact with the inner wall of the box body 1, and the surface of the push plate 9 is provided with a protrusion, the bottom of the push plate 9 is in contact with the surface of the first screen plate 6, and an electric push rod 10 is fixedly installed on one side of the box body 1, the telescopic end of the electric push rod 10 passes through one side of the box body 1, and the telescopic end of the electric push rod 10 is fixedly connected to the side of the push plate 9 away from the protrusion.
[0029] It should be noted that the protrusions can also disperse the aggregate particles that are stuck together when the aggregate particles collide.
[0030] By adopting the above scheme, through the use of the push plate 9 and the electric push rod 10, when a large amount of large-particle aggregates are retained on the first screen plate 6, the box door of the box body 1 is opened, and the combing plate 5 is rotated to the top of the first screen plate 6 by the motor 3. Under the premise that the combing plate 5 does not affect the movement of the push plate 9, the electric push rod 10 works to push the push plate 9 to move along the surface of the first screen plate 6, and the large-particle aggregates retained on the surface of the first screen plate 6 are pushed out of the box body 1, which can effectively avoid excessive large-particle aggregates being retained on the first screen plate 6, clogging the mesh holes of the first screen plate 6, and affecting the screening of the first screen plate 6.
[0031] In this embodiment, a slide rail 11 is fixedly connected to the inner wall of the box body 1, and a guide block 12 that slides with the slide rail 11 is fixedly connected to the side of the first screen plate 6. A through hole 13 is provided on the slide rail 11 and the first screen plate 6, and a pin 14 is slidably inserted in the through hole 13.
[0032] By adopting the above scheme, the cooperation of the slide rail 11 and the guide block 12 can facilitate the installation and disassembly of the first screen plate 6, and the cooperation of the through hole 13 and the pin 14 can facilitate the fixation of the first screen plate 6. When the first screen plate 6 needs to be taken out of the box body 1, the fixation of the first screen plate 6 can be released by directly removing the pin 14, so that the first screen plate 6 can be conveniently removed.
[0033] In this embodiment, the box body 1 is installed with a second screen plate 15, and the second screen plate 15 is slidably installed on the slide rail 11 through the guide block 12. The upper part of the second screen plate 15 is in contact with the bottom of the first screen plate 6, and the sides of the slide rail 11 and the second screen plate 15 are both provided with threaded holes 16 for installing bolts, and the number of the threaded holes 16 on the second screen plate 15 is set to be no less than two.
[0034] By adopting the above scheme, through the cooperation of the second screen plate 15 and the threaded holes 16, and by using bolts installed in the threaded holes 16 at different positions on the second screen plate 15, the mesh holes of the second screen plate 15 can be staggered with the mesh holes of the first screen plate 6 by a certain position, so that the aperture of the first screen plate 6 when feeding can be adjusted, so that the particle size of the sieve material of the first screen plate 6 can be adjusted as needed, which can improve the applicability of the equipment.
[0035] The working principle of this utility model:
[0036] When in use, after the aggregate particles are put into the box body 1 from the feed port of the box body 1, some particles with small particle sizes leak from the first screen plate 6 to the bottom of the box body 1, and the combing plate 5 is driven to rotate in the box body 1 through the rotation of the output end of the motor 3, so that the combing plate 5 collides with the aggregate particles retained on the first screen plate 6, breaks up the aggregate particles stuck together, and removes the aggregate particles blocking the mesh of the first screen plate 6, so that the small particles of material can fall from the first screen plate 6 to the bottom of the box body 1, which can break up the aggregate particles stuck together and effectively prevent the aggregate particles stuck together from blocking the mesh of the first screen plate 6;
[0037] When a large number of large aggregate particles are retained on the first screen plate 6, the box door of the box body 1 is opened, and the combing plate 5 is rotated to the top of the first screen plate 6 by the motor 3. Under the premise that the combing plate 5 does not affect the movement of the push plate 9, the push plate 9 is pushed to move along the surface of the first screen plate 6 by the electric push rod 10, and the large aggregate particles retained on the surface of the first screen plate 6 are pushed out of the box body 1, which can effectively prevent the first screen plate 6 from retaining too many large aggregate particles, blocking the mesh of the first screen plate 6, and affecting the screening of the first screen plate 6;
[0038] By using bolts installed in threaded holes 16 at different positions on the second screen plate 15, the mesh holes of the second screen plate 15 can be staggered with the mesh holes of the first screen plate 6 by a certain position, so that the aperture of the first screen plate 6 when feeding can be adjusted, so that the particle size of the sieve material of the first screen plate 6 can be adjusted as needed, which can improve the applicability of the equipment.
