[0020] Embodiment 1

[0021] Please refer to Figures 1 - 4 , the present invention provides a viscosity detection device for asphalt mixtures. The detection device includes an outer shell 1, a heating component, a temperature measuring component 10, a discharging component and a support base 15. The inner part of the outer shell 1 is fixedly connected with an inner tank 2, the material of the inner tank 2 is a metal material, the top of the outer shell 1 is fixedly installed with a feed hopper 3, and a feed valve is fixedly installed outside the feed hopper 3. The middle part of the outer shell 1 is movably sleeved with a rotating tube 4. The top end of the rotating tube 4 is fixedly connected with a forward and reverse motor 5, and a stirring component 6 is arranged on the side of the rotating tube 4. The stirring component 6 includes a connecting pipe 61. The connecting pipe 61 is fixedly connected to the side of the rotating tube 4, and a stirring pipe 62 is fixedly connected to the outside of the connecting pipe 61. One end of the connecting pipe 61 is fixedly connected with a scraper 63; In this embodiment, when the feed valve is opened, the asphalt mixture to be detected is added into the inner tank 2 from the feed hopper 3. Then, the forward and reverse motor 5 is turned on, causing the rotating pipe 4 to rotate, and the rotating pipe 4 drives the stirring assembly 6 to rotate, thus facilitating the stirring of the asphalt mixture inside the inner tank 2.

[0022] The heating assembly includes an intake pipe 7 and an exhaust pipe 8. The intake pipe 7 and the exhaust pipe 8 are respectively fixedly connected to the tops of both sides of the outer shell 1. Intake valves and exhaust valves are respectively fixedly installed on the outer parts of the intake pipe 7 and the exhaust pipe 8. The top of the intake pipe 7 is fixedly connected to one side of the top end of the rotating pipe 4 through an air delivery pipe 9, and the air delivery pipe 9 is a flexible pipe. In this embodiment, when the asphalt mixture in the inner tank 2 is being stirred, the intake valve is opened, enabling the hot air to flow into the interior of the outer shell 1 along the intake pipe 7, promoting contact between the hot air and the inner tank 2. In this way, the temperature on the surface of the inner tank 2 rises, facilitating the heating of the asphalt mixture in the inner tank 2. At the same time, the hot air enters the interior of the rotating pipe 4 along the air delivery pipe 9, and the hot air circulates inside the rotating pipe 4, the connecting pipe 61, and the stirring pipe 62. This can heat the asphalt mixture during the stirring process, enabling the asphalt mixture to be heated quickly and fully, thereby improving the heating effect of the asphalt mixture.

[0023] The temperature measuring assembly 10 is used to detect the temperature of the asphalt mixture in the inner tank 2. The temperature measuring assembly 10 includes a temperature sensing probe 101, a controller 102, and a warning lamp 103. The temperature sensing probe 101 is fixedly installed at the top of the inner cavity of the outer shell 1. The controller 102 and the warning lamp 103 are both fixedly connected to one side of the outer shell 1. The controller 102 includes a signal receiving module 102a, a signal processing module 102b, a numerical setting module 102c, and a circuit control module 102d. The input end of the signal receiving module 102a is signal-connected to the output end of the temperature sensing probe 101, and the output end of the signal receiving module 102a is signal-connected to the input end of the signal processing module 102b. The output end of the signal processing module 102b is signal-connected to the input end of the numerical setting module 102c. The output end of the numerical setting module 102c is signal-connected to the input end of the circuit control module 102d. The output end of the circuit control module 102d is electrically connected to the input end of the warning lamp 103. In this embodiment, when the asphalt mixture in the inner tank 2 is heated, the temperature induction probe 101 will detect the temperature in the inner tank 2 in real time, and transmit the detected temperature value information to the signal receiving module 102a in the form of a signal. The signal receiving module 102a will transmit the received signal to the signal processing module 102b, and the signal processing module 102b will amplify the signal and transmit the processed signal to the numerical setting module 102c. When the temperature value detected by the temperature induction probe 101 reaches the temperature value range set by the numerical setting module 102c, the circuit control module 102d will turn on the circuit of the warning light 103, causing the warning light 103 to alarm due to power-on, so that the detection personnel can be timely reminded to detect the viscosity of the asphalt mixture.

[0024] The discharging assembly includes a cross plate 11 and a drainage pipe 12. The cross plate 11 is fixedly sleeved outside the forward and reverse motor 5, and an electric push rod 13 is fixedly connected to the bottom of the cross plate 11. The electric push rod 13 is fixedly connected to the top of the outer shell 1, and the top of the electric push rod 13 and the bottom of the cross plate 11 are perpendicular to each other. The drainage pipe 12 is fixedly sleeved at the bottom of the inner tank 2, and a plugging block 14 is clamped at the top of the drainage pipe 12. The top of the plugging block 14 is movably sleeved with the bottom end of the rotating pipe 4. A beaker 16 is placed on the top of the support base 15. The support base 15 is fixedly connected to the bottom of the side of the outer shell 1. The beaker 16 is located directly below the bottom end of the drainage pipe 12. A timer 17 is fixedly installed on one side of the top of the support base 15; In this embodiment, when the temperature of the heated asphalt mixture reaches the temperature range required for viscosity detection, the electric push rod 13 is started to make it extend. The electric push rod 13 will drive the forward and reverse motor 5 to move vertically upward by using the cross plate 11, and the forward and reverse motor 5 will drive the rotating pipe 4 to move upward, so that the plugging block 14 will move upward under the drive of the rotating pipe 4, prompting the separation between the plugging block 14 and the drainage pipe 12. At this time, the asphalt mixture in the inner tank 2 will flow out along the drainage pipe 12 and fall into the beaker 16. When the asphalt mixture flows out from the bottom end of the drainage pipe 12, the timer 17 is turned on. By observing the time required for the asphalt mixture in the beaker 16 to reach 50 mL, the viscosity of the asphalt mixture is judged. That is, in the same temperature environment, the longer the required time, the higher the viscosity.

[0025] In summary, compared with most existing detection devices, the viscosity detection device for asphalt mixture in this embodiment has the following advantages: 1. By setting the rotating tube 4, the forward and reverse motor 5 and the stirring assembly 6, during the viscosity detection process of the asphalt mixture, it is convenient to stir the asphalt mixture inside the inner tank 2, enabling the asphalt mixture to be heated quickly and fully, saving the time required for heating the asphalt mixture, accelerating the subsequent viscosity detection process of the asphalt mixture, and thus bringing convenience to the viscosity detection of the asphalt mixture. 2. By setting the intake pipe 7, the exhaust pipe 8 and the gas transmission pipe 9, during the heating process of the asphalt mixture, it is not only convenient to transfer heat to the surface of the inner tank 2, enabling the asphalt mixture near the inner wall of the inner tank 2 to be heated better, but also convenient to utilize the hot gas to circulate inside the rotating tube 4, the connecting tube 61 and the stirring tube 62. In this way, the asphalt mixture near the center of the inner tank 2 can be heated, enabling the asphalt mixture to be heated quickly and fully, thereby improving the heating effect of the asphalt mixture. 3. By setting the temperature measuring assembly 10, during the heating process of the asphalt mixture, it is convenient to detect the temperature inside the inner tank 2 in real time. When the asphalt mixture reaches the temperature range required for viscosity detection, it can promptly alarm to remind the tester to perform the viscosity detection operation on the asphalt mixture, thus further bringing convenience to the viscosity detection of the asphalt mixture.

[0026] Embodiment Two

[0027] Please refer to Figure 5 and Figure 6 , the viscosity detection device for the asphalt mixture in this embodiment adds a rotating assembly 18 on the basis of Embodiment One. The rotating assembly 18 is located at the bottom of the beaker 16, and the rotating assembly 18 includes a protective cover 181. The protective cover 181 is fixedly connected to the top of the support base 15. A rotating motor 182 is fixedly installed inside the protective cover 181. A turntable 183 is fixedly connected to the output shaft of the rotating motor 182. A support block 184 is fixedly connected to the side of the top of the protective cover 181. A beaker fixing block is fixedly connected to the top of the turntable 183. The beaker fixing block is made of rubber material, and the top of the support block 184 is in contact with the bottom of the turntable 183. In this embodiment, when a viscosity detection is completed (that is, when the asphalt mixture in one beaker 16 reaches 50 mL), the rotating motor 182 is turned on, causing the turntable 183 to rotate 180 degrees. In this way, another empty beaker 16 on the turntable 183 will move to directly below the bottom end of the drainage tube 12, thus facilitating a timely re - viscosity detection of the asphalt mixture. At the same time, the beaker 16 originally filled with 50 mL can be taken out from the turntable 183, and a new empty beaker 16 can be placed. By continuously turning on the rotating motor 182 in the above - mentioned manner to change the position of the beaker 16, multiple viscosity detections of the asphalt mixture can be carried out, conveniently increasing the amount of data of the detection results, and thus improving the accuracy of the viscosity detection results of the asphalt mixture.

[0028] In summary, for the viscosity detection device of the asphalt mixture in this embodiment, by setting the rotating assembly 18, it is convenient to continuously change the position of the beaker 16 during the viscosity detection of the asphalt mixture. This facilitates rapid multiple detections of the viscosity of the asphalt mixture, increases the amount of data in the detection results, and thus improves the accuracy of the viscosity detection results of the asphalt mixture.

[0029] Working principle and usage process of the present invention: First, open the feed valve, and add the asphalt mixture to be detected from the feed funnel 3 into the inner tank 2. Then, turn on the forward and reverse motor 5, causing the rotating tube 4 to rotate. The rotating tube 4 will drive the stirring assembly 6 to rotate, thus facilitating the stirring of the asphalt mixture inside the inner tank 2. At the same time, open the intake valve, so that the hot air can flow into the interior of the outer shell 1 along the intake pipe 7, promoting contact between the hot air and the inner tank 2. In this way, the temperature on the surface of the inner tank 2 will rise, facilitating the heating of the asphalt mixture in the inner tank 2. And the hot air will enter the interior of the rotating tube 4 along the air delivery pipe 9, and the hot air will circulate inside the rotating tube 4, the connecting tube 61, and the stirring tube 62, enabling heating of the asphalt mixture during the stirring process. Next, when the asphalt mixture in the inner tank 2 is being heated, the temperature induction probe 101 will continuously detect the temperature in the inner tank 2 and transmit the detected temperature value information to the signal receiving module 102a in the form of a signal. The signal receiving module 102a will transmit the received signal to the signal processing module 102b, and the signal processing module 102b will amplify the signal and transmit the processed signal to the numerical setting module 102c. If the temperature value detected by the temperature induction probe 101 reaches the temperature value range set by the numerical setting module 102c, the circuit control module 102d will turn on the circuit of the warning light 103, causing the warning light 103 to alarm due to power-on, thus being able to timely remind the tester to perform viscosity detection on the asphalt mixture. Immediately afterwards, when the temperature of the heated asphalt mixture reaches the temperature range required for viscosity detection, start the electric push rod 13 to make it extend. The electric push rod 13 will drive the forward and reverse motor 5 to move vertically upward through the cross plate 11, and the forward and reverse motor 5 will drive the rotating tube 4 to move upward, causing the plugging block 14 to move upward under the drive of the rotating tube 4, promoting separation between the plugging block 14 and the drainage tube 12. At this time, the asphalt mixture in the inner tank 2 will flow outwards along the drainage tube 12 and fall into the beaker 16. And when the asphalt mixture flows out from the bottom end of the drainage tube 12, turn on the timer 17. By observing the time required for the asphalt mixture in the beaker 16 to reach 50 mL, the viscosity of the asphalt mixture is judged. That is, in the same temperature environment, the longer the required time, the higher the viscosity. Finally, when a viscosity detection is completed (i.e., when the asphalt mixture inside a beaker 16 reaches 50 mL), the rotation motor 182 is turned on, causing the turntable 183 to rotate 180 degrees. In this way, another empty beaker 16 on the turntable 183 will move to directly below the bottom end of the drainage pipe 12, which facilitates timely performing another viscosity detection on the asphalt mixture. At the same time, the beaker 16 that was originally filled with 50 mL can be removed from the turntable 183, and a new empty beaker 16 can be placed. By continuously turning on the rotation motor 182 as described above to change the position of the beaker 16, multiple viscosity detections can be performed on the asphalt mixture, which conveniently increases the amount of data of the detection results, thereby improving the accuracy of the viscosity detection results of the asphalt mixture.
