[0028] First embodiment:

[0029] The utility model provides a technical solution: an asphalt mixture circulating heating stirring device, comprising a support frame 1, a mixing drum 2 is fixedly connected to the support frame 1, a feeding plate 3 and a temperature controller 8 are connected to the mixing drum 2, an exhaust plate 4 is fixedly connected to the mixing drum 2, a gas filter 9 is clamped on the exhaust plate 4, a discharge plate 10 is connected below the mixing drum 2, a stirring blade 11 is rotatably connected to the mixing drum 2, a support plate 13 is provided below the discharge plate 10, self-locking structures 5 are provided on both sides of the exhaust plate 4, the self-locking structure 5 is clamped on the gas filter 9, a clamping structure 6 is provided in the support frame 1, the clamping structure 6 is connected to the support plate 13, the clamping structure 6 is connected to the outside of the discharge plate 10, and a dredging structure 7 is provided in the support plate 13;

[0030] The self-locking structure 5 includes a limit rotating plate 501, a positioning rod 502, a coil spring 1 504 and two ratchet bars 507. Ratchets 505 are connected to both sides of the limit rotating plate 501, and coil spring 2 506 is connected to the opposite side of the two ratchets 505.

When the ratchet bar 507 is disengaged from the ratchet 505, the limit rotating plate 501 will be reset by coil spring 2 506, so that coil spring 2 506 and ratchet bar 507 play a certain auxiliary role for the limit rotating plate 501 and the ratchet bar 507, thereby avoiding dislocation of the limit rotating plate 501 and the ratchet bar 507 when flipping.

[0033] Second embodiment:

[0034] Specifically, such as Figure 4-5As shown, the clamping structure 6 includes two connecting plates 601, a guide rod 602, two positioning blocks 603 and a bottom plate 606. The two positioning blocks 603 are connected to the outer surface of the blanking plate 10. The spacing between the two positioning blocks 603 is equal. The two connecting plates 601 are connected to the right side of the support plate 13. The guide rod 602 is fixedly connected to the right side of the support frame 1. The guide rod 602 is rotatably connected to a clamping plate 604. The clamping plate 604 is clamped in the two connecting plates 601. Bolts 605 are provided in the clamping plate 604. The clamping plate 604 is connected to the support frame 1 through the bolts 605. The support plate 13 is clamped in the positioning blocks 603. The bottom plate 606 is fixedly connected in the support frame 1. The support plate 13 is overlapped on the clamping structure 6, and the dredging structure 7 includes a threaded rod 1 701, a threaded rod 2 702, an anti-slip belt 703 and a motor 1 704. The threaded rod 1 701 is rotatably connected to the support plate 13, the threaded rod 2 702 is rotatably connected to the support plate 13, the threaded rod 1 701 is transmission-connected to the threaded rod 2 702 through the anti-slip belt 703, the output shaft of the motor 1 704 is connected to the threaded rod 2 702, the motor 1 704 is connected under the support plate 13, the threaded rod 1 701 is externally threadedly connected to a sleeve plate 705, one side of the sleeve plate 705 is connected to a support inclined plate 706, a dispersion rod 707 is rotatably connected to the support inclined plate 706, a motor 2 708 is fixedly connected under the support inclined plate 706, and the output shaft of the motor 2 708 is connected to the dispersion rod 707.

[0036] Working principle, when using:

[0037] When the circulating heating and stirring device is stirring the asphalt mixture, the asphalt mixture can be fed into the mixing drum 2 through the feed plate 3, and then the built-in circulating heating pipe is controlled by the temperature controller 8 to operate, which can ensure that the inside of the mixing drum 2 is at a temperature that can be mixed and stirred. When the asphalt mixture is stirred, the gas filter 9 can be clamped to the top of the exhaust plate 4, and then a pulling force is applied to the ratchet 507. The ratchet 507 will rotate around the positioning rod 502. When the ratchet 507 rotates, the coil spring 1 504 will be deformed. When the ratchet 507 is disengaged from the ratchet wheel 505, the limit rotating plate 501 will be reset by the action of the coil spring 2 506. After the reset, the limit rotating plate 501 will be clamped with the gas filter 9. After the ratchet 507 is released, it will be restored by the coil spring 1 504. The ratchet 507 will overlap with the ratchet wheel 505. When the stirring blade 11 is running at a high speed in the mixing drum 2, the asphalt mixture will be fully stirred.

[0038] When the asphalt mixture needs to be unloaded, the support plate 13 can be clamped in the positioning block 603, and the bottom end of the support plate 13 will contact the bottom plate 606, and the two connecting plates 601 on the side of the support plate 13 will be inserted into the support frame 1. When a thrust is applied to the clamping plate 604, it will flip around the guide rod 602. After the clamping plate 604 and the two connecting plates 601 are inserted, they are threadedly connected to the support frame 1 through bolts 605;

[0039] Then the arc-shaped sealing plate 12 is slid in an arc shape in the blanking plate 10. After the arc-shaped sealing plate 12 slides, the asphalt mixture inside will be discharged along with the blanking plate 10. During the discharge process, the dispersion rod 707 is driven by motor 2 708 to rotate, and motor 1 704 will drive threaded rod 2 702 to rotate forward and reverse. Threaded rod 2 702 is connected to threaded rod 1 701 through anti-slip belt 703, so that the sleeve plate 705 supporting the side of the inclined plate 706 will move on the outer surface of threaded rod 1 701 and threaded rod 2 702, and the dispersion rod 707 will move back and forth in the blanking plate 10 when rotating.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
