[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, a high-viscosity asphalt viscosity and toughness detection device includes a head 1 with a motor disposed therein, and a probe rod 2 is threadedly connected to the output end of the motor;

[0022] The probe rod 2 includes a stirring head 3, the cross section of which is an I-shaped structure, and arc holes 31 arranged in a circumferential array are opened thereon, one end of the arc holes 31 faces upward, and the other end is located on the side of the stirring head 3;

[0023] The side wall of the stirring head 3 is provided with a protrusion 4 arranged on one side of the arc-shaped hole 31 .

[0024] Furthermore, during the installation process, the probe rod 2 includes a connecting rod 21, and a wiring copper slot 22 is provided at a first end of the connecting rod 21;

[0025] The above embodiment also includes a conductive part 5 slidably disposed on the output end of the motor, and the conductive part 5 is nested and connected with the wiring copper slot 22 .

[0026] Furthermore, symmetrically arranged elastic members 6 are provided on the conductive portion 5 , and the elastic members 6 are of a V-shaped structure.

[0027] Specifically, in the embodiment, the connecting rod 21 is inserted into the boring of the output end of the motor and threadedly connected, so that the wiring copper slot part 22 contacts the conductive part 5. At this time, the elastic part 6 is deformed, so that the pressure sensor 7 is connected to the circuit board data in the head 1.

[0028] As another embodiment further provided by the utility model, the probe rod 2 includes a guide rod 23 integrally connected to the stirring head 3, a first end of the guide rod 23 is slidably arranged with a second end of the connecting rod 21, and a pressure sensor 7 is arranged in the second end of the connecting rod 21.

[0029] Secondly, an equidistant spring 8 is arranged in the connecting rod 21 . In a default state, the equidistant spring 8 pushes the end of the guide rod 23 to contact the detection end of the pressure sensor 7 .

[0030] In the above technology, the arc-shaped hole 31 is used to guide the flow during the rotation to move the stirring head 3 upward. The higher the viscosity of the asphalt, the greater the upward force of the stirring head 3, and thus the greater the pressure applied to the pressure sensor 7. Compared with the traditional rotation measurement method, this detection method greatly reduces the increase in the operating load of the motor.
