[0039] In this embodiment: the feed pipe 11 is convenient for feeding the asphalt raw material into the interior of the stirring device body 1.

[0040] In an optional embodiment: a feed hopper 12 is fixedly provided at the top of the feed pipe 11 , a filter screen 13 is fixedly provided inside the feed hopper 12 , a mounting seat 14 is fixedly provided at the top of the feed hopper 12 , and a motor 15 is fixedly provided at the top of the mounting seat 14 .

[0041] In this embodiment, the feed hopper 12 is convenient for reducing the probability of spilling the asphalt raw material when it is poured.

[0042] In an optional embodiment: the side of the transmission shaft of the motor 15 is rotatably connected to the inside of the mounting seat 14 , a rotating rod 16 is fixedly disposed at the bottom end of the transmission shaft of the motor 15 , and a plurality of stirring plates 17 are fixedly disposed on the side of the rotating rod 16 .

[0043] In this embodiment, the motor 15 is convenient for driving the rotating rod 16 to rotate, thereby driving the stirring plate 17 to rotate.

[0044] The working principle and use process of the utility model are as follows: asphalt raw materials are poured into the interior of the stirring device body 1, the asphalt is heated and stirred by the heating device and the stirring device inside the stirring device body 1, and the exhaust gas generated by the heating is filtered by the filtering device on the side of the stirring device body 1. After the asphalt is heated for a period of time, the stirring device is turned off. Initially, the collecting groove 10 is blocked by the inner wall of the sealing tube 2, and the flow groove 9 is sealed by the outer side of the collecting tube 5, so that the asphalt cannot enter the collecting tube 5. The sealing tube 2 and the collecting tube 5 are placed in the interior of the stirring device body 1 through the placement groove. At this time, the pull plate 7 is pulled to drive the limit shaft 8 to move upward, so that the limit shaft 8 is disengaged from the second limit hole, so that the rotating ring 4 can rotate, so that the collecting tube 5 can be rotated, the collecting tube 5 is rotated 180 degrees, so that the collecting tank 10 is rotated 180 degrees. At this time, the collecting tank 10 is connected with the flow tank 9, and the asphalt of different depths enters the collecting tank 10 of different depths respectively. After the collection is completed, the collecting tube 5 is rotated 180 degrees, so that the collecting tank 10 is sealed by the sealing tube 2, the pull plate 7 is loosened, and the pull plate 7 is pulled by the reset spring 6 to move the pull plate 7 downward, thereby driving the limit shaft 8 to move downward, so that the limit shaft 8 enters the first limit hole and the second limit hole, so that the rotating ring 4 and the limit ring 3 are fixed together, so that the collecting tube 5 and the sealing tube 2 are fixed together to prevent the asphalt in the collecting tank 10 from leaking. At this time, the collecting tube 5 and the sealing tube 2 are taken out, and the sealing tube 2 is rotated. The collecting tank 10 is opened, and the stirring conditions of asphalt at different depths can be observed. When the standard is reached, the discharge pipe at the bottom of the stirring device body 1 is opened to discharge the asphalt. When the stirring condition of the asphalt does not reach the standard, the stirring device is continuously started to stir the asphalt, so that the device is convenient for simultaneously checking the mixing conditions of asphalt at different depths, avoiding the asphalt stirring time being too long to reduce the processing efficiency, or the stirring time being too short to reduce the stirring quality. The asphalt enters the stirring device body 1 through the feed pipe 11, and the asphalt is prevented from being scattered when pouring the asphalt through the feed hopper 12. The large asphalt particles in the asphalt are blocked by the filter screen 13 to avoid the large asphalt particles from reducing the processing quality of the asphalt. Since there is a certain friction between the asphalt particles, When the asphalt reaches the filter 13, it is easy to stack on the filter 13, which reduces the feeding efficiency of the asphalt. The motor 15 is started, and the transmission shaft of the motor 15 drives the rotating rod 16 to rotate, thereby driving the stirring plate 17 to rotate. The asphalt particles are stirred by the stirring plate 17, which is convenient for accelerating the speed of small particles of asphalt passing through the filter 13. When all the small particles of asphalt have passed through the filter 13, the feed pipe 11 is removed, so that the large particles of asphalt remaining in the feed hopper 12 can be poured out, so that the device can easily block the large particles of asphalt in the asphalt through the filter 13, avoiding the large particles of asphalt reducing the processing quality of the asphalt, and the asphalt can be stirred to accelerate the speed of asphalt passing through the filter 13, which is convenient for improving the feeding efficiency of the asphalt.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
