[0034] One end of the pipe body 12 is connected to the sampling cylinder 11, and the pipe body 12 is internally communicated with the sampling cylinder 11; the lower end of the sampling cylinder 11 is communicated with the upper end of the heating ring 15, the upper end of the heating ring 15 is fixedly connected to the sampling cylinder 11, the heating end of the heating element 2 is connected to the heating ring 15, and the heating element 2 is used to heat the heating ring 15; the pipe body 12 is movably sleeved on the movable rod 13, and one end of the movable rod 13 is fixedly connected to the sealing plate 14; the sealing plate 14 is arranged inside the heating ring 15, and the sealing plate 14 is used to open or close the opening through which the heating ring 15 communicates with the sampling cylinder 11.

[0035] In an embodiment of the present invention, the multi-condition asphalt sampling device further includes a filtering component 16; the sealing plate 14 is arranged above the filtering component 16, and the filtering component 16 is fixedly arranged inside the lower end of the heating ring 15, and is used to filter the asphalt entering the heating ring 15 and block impurities in the asphalt.

[0036] In an embodiment of the present invention, the multi-condition asphalt sampling device further includes a control structure, and the control structure includes a controller 31 and a power supply; the controller 31 is electrically connected to the power supply and the heating element 2 respectively.

[0037] In an embodiment of the present invention, the controller 31 is further electrically connected to a temperature sensor 32, and the temperature sensor 32 is arranged inside the sampling cylinder 11 and is used to detect the temperature of the asphalt inside the sampling cylinder 11.

[0038] Further, the power supply is a storage battery or an external power supply. In an embodiment of the present invention, the filtering component 16 is a filter screen or a grille.

[0039] In an embodiment of the present invention, the heating element 2 is an electric heating element.

[0040] In an embodiment of the present invention, the heating element 2 is an electric heating wire.

[0041] In an embodiment of the present invention, both the heating ring 15 and the filtering component 16 are made of heat-conducting metal.

[0042] In an embodiment of the present invention, two cross bars 121 are symmetrically arranged at the upper end of the pipe body 12, and the two cross bars 121 are fixedly connected to the pipe body 12; when sampling, the two cross bars 121 are used for the sampling personnel to respectively hold the two cross bars 121 with both hands and insert the sampling cylinder 11 into the asphalt, which is convenient for the sampling personnel to exert force downward.

[0043] In an embodiment of the present invention, the controller 3l is arranged on one of the cross bars 121.

[0044] In an embodiment of the present invention, the upper end of the movable rod 13 is arranged outside the pipe body 12, the upper end of the movable rod 13 is provided with a thread, and the limit nut 131 is threadedly connected to the upper end of the movable rod 13.

[0045] In an embodiment of the present utility model, a circular cutting edge 151 is provided at the lower end of the heating ring 15.

[0046] When the present utility model is in use, the heating ring 15 is inserted into the asphalt to be sampled, and the heating element 2 is used to heat the heating ring 15. At this time, the movable rod 13 moves downward relative to the tube body 12, driving the sealing plate 14 away from the opening where the heating ring 15 communicates with the sampling cylinder 11. The heated asphalt enters the sampling cylinder 11 from the opening where the heating ring 15 communicates with the sampling cylinder 11. After sampling, the sealing plate 14 is moved upward relative to the tube body 12 by the movable rod 13 to seal the opening where the heating ring 15 communicates with the sampling cylinder 11. At the same time, the upper end of the movable rod 13 can be fixed to the upper end of the tube body 12 by tightening the limit nut 131 (making the limit nut 131 close to the sealing plate 14). At this time, the movable rod 13 cannot move downward anymore. Then the heating ring 15 can be withdrawn from the asphalt.

[0047] When it is necessary to release the asphalt in the sampling cylinder 11, loosen the limit nut 131 (that is, make the limit nut 131 away from the sealing plate 14), so that the movable rod 13 can move downward to open the opening where the heating ring 15 communicates with the sampling cylinder 11, and the asphalt can be released.

[0048] When sampling the liquid asphalt in the tanker, the sampler can sample the asphalt at the corresponding position of the tanker as needed. By inserting the sampling cylinder 11 to the corresponding depth, the upper, middle, and lower layers of the asphalt in the liquid state can be sampled.

[0049] Furthermore, the heating element 2 can be controlled by the controller 31, and at the same time, the temperature of the asphalt can be detected by the temperature sensor 32.

[0050] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
