The control mechanism includes a control panel 2 and a main control microcontroller 1. The control panel 2 is arranged on the base 14 and is electrically connected to the main control microcontroller 1. The moving mechanism includes a cavity, a bifurcated rod 17 and an electric telescopic rod 3, a heating rod 3 and an oscillating stirrer 5 respectively electrically connected to the main control microcontroller 1. The cavity is arranged on the base 14, the fixed end of the electric telescopic rod 3 is arranged in the cavity, the moving end of the electric telescopic rod 3 is connected to the bifurcated rod 17, and the bifurcated rod 17 is respectively connected to the heating rod 3 and the oscillating stirrer 5.

The beaker 16 is arranged below the cavity, the electronic thermometer 8 is arranged in the beaker 16, and the measuring frame 15 is arranged in the beaker 16.

[0022] For example, the control panel 2 is provided with "heating" and "oscillation stirring" buttons. When an asphalt sample needs to be prepared for a softening test, the staff can place the sample ring on the round hole of the measuring frame 15, put on the steel ball clamp, put in the steel ball, and then place the measuring frame 15 in the beaker 16. The staff then presses the "heating" and "oscillation stirring" buttons, and the main control microcontroller 1 sends a signal instruction to the electric telescopic rod 3 set in the cavity, so that the electric telescopic rod 3 moves toward the beaker 16, and then drives the heating rod 3 and the oscillation stirrer 5 on the forked rod 17 to move into the beaker 16, so that the liquid in the beaker 16 can be evenly heated and can also be oscillated and stirred. The staff then observes the temperature value of the electronic thermometer 8 during the falling process of the steel ball to complete the test record of asphalt softening. This device can evenly heat the liquid in the beaker 16 so that the heated temperature of the liquid in the beaker 16 is uniform, thereby ensuring the accuracy of the test results.

[0026] For example, in order to facilitate the staff to view the asphalt softening test, the softening process record, such as the heating time, temperature time and other process records, can be printed out by the printer 7.

[0027] In the above embodiment, the control panel 2, electric telescopic rod 3, heating rod 3, oscillating stirrer 5, display screen 6 and printer 7 can all adopt existing models known to those skilled in the art; the main control microcontroller 1 can adopt an STM32 microcontroller.
