[0026] Working principle:

[0027] During the measurement, firstly, the asphalt mixture sample is placed on the sample table 3 and the box door 12 is closed. It should be noted that at this time, the heating lamp tube group 21 has been horizontally inserted into the middle of the cavity of the test box 1 from right to left. At this time, the heating lamp tube group 21 can be controlled by the display table 7 to heat the asphalt mixture sample. A slight odor will be generated during the heating process. At this time, the air in the cavity of the test box 1 can be evacuated through the air filter 5, and the gas can be discharged into the water in the water tank body 522 to filter out the odor.

[0028] In addition, when the heating time is reached, the heating lamp group 21 needs to be pulled to the right and outward to connect the test needle 4 with the asphalt mixture sample, so that the needle penetration measurement can be performed. During the measurement, it is only necessary to cut off the power to the electromagnetic suction cup 43, and the test needle 44 can fall freely and be inserted into the asphalt mixture sample. The scanner 6 then scans the insertion depth of the test needle 44 on the asphalt mixture sample and transmits it to the display station 7 for analyzing the viscosity of the asphalt mixture. It should be noted that the measurement of the test needle 44 requires multiple position measurements, and the multiple position measurements of the test needle 44 are achieved by driving the electromagnetic suction cup 43 to move left and right on the cross rail 41 through the slider 42.
