[0035] During use of this solution, the bottom output end of the dual-axis motor 501 drives the rotating rod 502 to rotate, causing the multiple sets of connecting round rods 503 and stirring blades 504 to rotate, thereby stirring and mixing the asphalt concrete raw materials inside the mixing pot 1. At the same time, multiple scrapers 506 rotate along the inner wall of the mixing pot 1 to scrape off the asphalt concrete raw materials splashed and attached to the inner wall of the mixing pot 1, so that the asphalt concrete raw materials are fully mixed and the adhesion and residue of the asphalt concrete raw materials are reduced.

[0036] like Figure 2-Figure 3 As shown, the rotational oscillation mechanism 6 includes a plurality of sliding plates 601, the outer walls of the plurality of sliding plates 601 are respectively slidably connected to the inner walls of the plurality of rectangular frames 505, a first spring 605 is fixedly connected between the top ends of the plurality of sliding plates 601 and the inner top ends of the plurality of rectangular frames 505, the bottom ends of the plurality of sliding plates 601 are fixedly connected to movable rods 602, and the inner bottom ends of the rectangular frames 505 are provided with fitting through holes, the bottom ends of the plurality of movable rods 602 pass through the fitting through holes and are fixedly connected to movable hemispheres 603, the bottom end of the cover plate 2 is fixedly connected to a plurality of fixed hemispheres 604, and the movable hemispheres 603 are in contact with the fixed hemispheres 604.

[0038] like Figure 1 and Figure 4-5 As shown, a pair of dust collection mechanisms 7 each include a pair of connecting elbows 701, the bottom ends of the pair of connecting elbows 701 are fixedly connected to the top of the feed pipe 3, the inner walls of the pair of connecting elbows 701 are fixedly connected with a filter screen 702, the ends of the pair of connecting elbows 701 away from each other are fixedly connected with a collecting frame 703, and the collecting frame 703 is fixedly connected to the top of the cover plate 2 through a pair of vertical plates, the ends of the pair of collecting frames 703 away from each other are fixedly connected with an exhaust fan 704, an air guide hole is drilled at one end of the collecting frame 703 close to the exhaust fan 704, and a breathable partition plate 705 is fixedly connected to the inner wall of the air guide hole, an insulation pipe 706 is fixedly connected between the bottom ends of the pair of exhaust fans 704 and the top of the cover plate 2, and a dust cleaning mechanism 8 is provided between the top output end of the dual-axis motor 501 and the interior of the two pairs of collecting frames 703.

[0039] During the use of this solution, when the asphalt concrete raw materials are fed and vibrated, a pair of vacuum fans 704 respectively extract the hot air inside the mixing pot 1 and the feeding pipe 3 through a pair of connecting elbows 701, so that the dust scattered upwards enters the collecting frame 703 with the air flow for collection. At the same time, the filter plate 702 blocks the broken raw materials outside the dust, thereby reducing the waste of asphalt concrete raw materials. Under the blocking of the breathable partition 705, the extracted hot air is reintroduced into the mixing pot 1 through the insulation pipe 706, thereby reducing the heat loss and ensuring its heating effect. Moreover, the front end of the collecting frame 703 can be flipped open to facilitate the staff to clean the dust inside it.

[0040] like Figure 1 and Figure 5-Figure 6As shown, the dust cleaning mechanism 8 includes a first bevel gear 801 fixedly connected to the top output end of the dual-axis motor 501, the outer wall of the first bevel gear 801 is meshedly connected with a pair of second bevel gears 802, and the ends of the pair of second bevel gears 802 that are away from each other are fixedly connected with a rotating round rod, the top of the cover plate 2 is fixedly connected with a pair of side connecting plates 804, and the rotating round rod is rotatably connected to the side connecting plates 804 through bearings, the outer walls of the pair of rotating round rods are sleeved with eccentric wheels 803, and the tops of the pair of eccentric wheels 803 are provided with U-shaped plates 805 that contact them, and the tops of the pair of U-shaped plates 805 are fixedly connected with top plates 806. A movable plate 809 is provided inside the collection frame 703, and the top of the movable plate 809 is fixedly connected to a lifting rod 807. A circular hole is drilled at the inner top of the collection frame 703, and the top of the lifting rod 807 passes through the circular hole and is connected to the top plate 806.

During the rotation of the pair of eccentric wheels 803, when the eccentric ends thereof come into contact with the U-shaped plate 805, they are squeezed to move upward, so that the U-shaped plate 805 drives the lifting rod 807 to move upward through the top plate 806. The lifting rod 807 drives the cleaning brush body 8010 and the knocking hammer rod 8011 to move upward through the movable plate 809, so that the cleaning brush body 8010 cleans the surface of the air permeable partition 705.

At the same time, the knocking hammer rod 8011 contacts and knocks the inner bottom end of the collecting frame 703, so that the dust on the surface of the cleaning brush body 8010 and the inner wall of the collecting frame 703 falls off, so as to facilitate subsequent cleaning and collection.

[0045] During the use of this solution, after the asphalt concrete is vibrated and mixed, the bolts on the cover plate 2 and the lifting straight plate 903 are removed, and the two pairs of electric telescopic rods 1102 push the two pairs of mounting plates 1101 to move upward, so that the cover plate 2 and the structural components thereon move upward, and the corresponding rack plate 1103 also moves upward, and drives the rotating gear 1104 to rotate through the meshing transmission action, and the rotating gear 1104 drives the connecting long rod 1105 and the rubber ball rod rack 1106 to rotate, so that the rubber ball rod rack 1106 repeatedly knocks on the ladder frame 1107 connected to the mounting plate 1101 during the rotation process, generating vibration, which is transmitted to the cover plate 2 through the mounting plate 1101, and the asphalt concrete on the cover plate 2 and its structural components falls off by the vibration effect, reducing adhesion, so that the asphalt concrete inside the mixing pot 1 can be fully discharged later, reducing residue and waste.

[0046] The present invention provides an environmentally friendly asphalt concrete oscillating mixing device, the working principle of which is as follows: a plurality of asphalt concrete raw materials enter into a mixing pot 1 through a pair of feed pipes 3 respectively, at which time, a plurality of heating rods 901 cooperate with a heat reflecting film 902 to fully heat the inside of the mixing pot 1 and provide a heating environment, then, the bottom output end of the dual-axis motor 501 drives the rotating rod 502 to rotate, so that a plurality of groups of connecting round rods 503 and stirring blades 504 rotate, and the asphalt concrete raw materials inside the mixing pot 1 are stirred and mixed, and at the same time, a plurality of rectangular frames 505 and scrapers 506 rotate along the inner wall of the mixing pot 1, and the asphalt concrete raw materials splashed and attached to the inner wall of the mixing pot 1 are scraped off for full mixing, and when the plurality of rectangular frames 505 rotate The plurality of movable rods 602 and the fixed hemisphere 604 are driven to rotate along the bottom end of the cover plate 2, and in the process of rotation, they repeatedly contact and move away from the plurality of movable hemispheres 603, so that the fixed hemisphere 604 repeatedly moves away from and contacts the bottom end of the cover plate 2 under the elastic action of the movable rod 602 and the first spring 605, and drives the connecting round rod 503 and the stirring blade 504 and the scraper 506 to vibrate during the stirring process, and the asphalt concrete raw materials are vibrated and mixed. At the beginning of feeding and vibrating mixing, the two pairs of exhaust fans 704 respectively extract the hot air inside the mixing pot 1 and the pair of feeding pipes 3 through the two pairs of connecting elbows 701, and filter through the filter screen 702, so that the dust scattered upwards enters the collection frame 703 with the air flow for collection.

During the rotation of the pair of eccentric wheels 803, when the eccentric end thereof contacts the U-shaped plate 805, it squeezes it to move upward, so that the U-shaped plate 805 drives the lifting rod 807 to move upward through the top plate 806, and the lifting rod 807 drives the cleaning brush body 8010 and the knocking hammer rod 8011 to move upward through the movable plate 809, so that the cleaning brush body 8010 cleans the surface of the air-permeable baffle 705, and when the eccentric end thereof is away from the U-shaped plate 805, the second bevel gear 802 is driven to rotate. The elastic action of the spring 808 drives the lifting rod 807 to move downward, and drives the cleaning brush body 8010 and the knocking hammer rod 8011 to move downward again through the movable plate 809, so that the cleaning brush body 8010 cleans the surface of the breathable partition 705 again to prevent the dust from concentrating on its surface and causing blockage. At the same time, the knocking hammer rod 8011 contacts and knocks the inner bottom end of the collecting frame 703, so that the dust on the surface of the cleaning brush body 8010 and the inner wall of the collecting frame 703 falls off, and the U-shaped plate 805 drives the toggle rod 904 and multiple toggle blocks 905 to move up and down when moving up and down, toggle the hot air inside the connecting sleeve frame 4 to flow and alternately mix, and evenly heat the inside of the mixing pot 1. After the asphalt concrete is shaken and mixed,Remove the bolts on the cover plate 2 and the lifting straight plate 903, and the two pairs of electric telescopic rods 1102 push the two pairs of mounting plates 1101 to move upward, so that the cover plate 2 and the structural components thereon move upward, and the corresponding rack plate 1103 also moves upward, and drives the rotating gear 1104 to rotate through the meshing transmission action, and the rotating gear 1104 drives the connecting long rod 1105 and the rubber ball bar rack 1106 to rotate, so that the rubber ball bar rack 1106 repeatedly knocks the ladder frame 1107 connected to the mounting plate 1101 during the rotation process, generating vibration, which is transmitted to the cover plate 2 through the mounting plate 1101, shaking off the asphalt concrete on the cover plate 2 and its structural components, and after the mixing pot 1 and the cover plate 2 are disassembled and separated, the asphalt concrete is discharged.
