At the same time, when it is added to the asphalt mixing drum after mixing, the height of the asphalt mixing drum is different. The height of the device is not convenient for adding to the asphalt mixing drum, so it does not meet the existing needs. In this regard, we propose an anti-rutting agent adding mechanism for asphalt mixing. Utility Model Content

[0011] Preferably, a PLC controller is installed at the front end of the workbench, and the input end of the PLC controller is electrically connected to the output end of the weighing sensor, a solenoid valve is installed on the lower side of one side of the liquid material barrel, and the input end of the solenoid valve is electrically connected to the output end of the PLC controller, and an infusion tube is installed at one end of the solenoid valve, and the infusion tube extends to the bottom of the workbench.

[0012] Preferably, a second motor is provided at the upper end of the transmission cavity, and the output end of the second motor is transmission-connected to the threaded rod via a coupling.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model provides support columns on both sides of the workbench. When adding, the user starts the second motor, and the second motor rotates the threaded rod, thereby driving the cross block to move vertically up and down. When the cross block moves up and down, the extension block synchronously drives the support feet to move, and then the support columns can be raised and lowered in height under the support of the support feet, and the workbench can be raised and lowered synchronously, so that the height of the workbench can be adjusted, which is convenient for adding anti-rutting agent to asphalt mixing drums of different heights, and has good practicality.

[0018] 2. The utility model opens a conveying cavity on one side of the workbench to allow the solid anti-rutting agent to enter the solid material box. When the first motor is started, the spiral conveying rod can rotate synchronously. The rotation of the spiral conveying rod will drive the solid anti-rutting agent to be spirally conveyed, which can avoid the accumulation of the solid anti-rutting agent. When the rotation of the first motor is ensured not to change its rotation speed, uniform conveying can be performed, thereby ensuring the amount of solid anti-rutting agent conveyed per unit time. The amount of solid anti-rutting agent added can be changed simply by changing the rotation time of the first motor, which is easy to use.

[0019] 3. The utility model provides a weighing sensor at the upper end of the weighing sensor. When the liquid anti-rutting agent is added into the liquid material barrel, the weighing sensor can weigh the added liquid anti-rutting agent. When the appropriate amount is reached, the solenoid valve will be opened through the PLC controller, so that the liquid anti-rutting agent can be transported to the cooling mixing barrel below through the delivery pipe, thereby realizing the addition of the liquid anti-rutting agent and increasing the scope of application.

[0030] When in use, start the second motor 13 to make the threaded rod 14 drive the cross block 15 to rotate. Under the guidance of the guide rod 16, the rotation of the cross block 15 will be converted into vertical movement up and down, thereby driving the extension block 17 to make the supporting foot 18 move synchronously. Since the supporting foot 18 is in contact with the ground, the supporting column 1 can be raised and lowered, so that the height of the workbench 2 can be adjusted, which is convenient for adding anti-rutting agent to asphalt mixing drums of different heights.

[0031] See also Figure 2 A first motor 5 is disposed behind the conveying chamber 19, and the output end of the first motor 5 is connected to the screw conveying rod 6 through a coupling. The first motor 5 provides power for the rotation of the screw conveying rod 6, which facilitates the conveying of the solid anti-rutting agent.

[0032] See also Figure 1 , Figure 2 and Figure 3 A PLC controller 3 is installed at the front end of the workbench 2, and the input end of the PLC controller 3 is electrically connected to the output end of the weighing sensor 9. A solenoid valve 10 is installed on the lower side of one side of the liquid barrel 8, and the input end of the solenoid valve 10 is electrically connected to the output end of the PLC controller 3.

[0037] Working principle: when in use, start the second motor 13, and the threaded rod 14 is rotated under the transmission of the coupling, and the threaded rod 14 will drive the cross block 15 to rotate synchronously. Since the cross block 15 and the guide rod 16 are slidingly matched, the cross block 15 will be axially limited by the guide rod 16, so that the rotation of the cross block 15 will be converted into vertical movement up and down. When the cross block 15 moves up and down, it will drive the synchronous movement of the extension block 17, so that the extension block 17 can drive the supporting foot 18 to move synchronously. Since the supporting foot 18 is in contact with the ground, the support column 1 can be lifted up and down, so that the height adjustment of the workbench 2 can be realized, which is convenient for adding anti-rutting agent to asphalt mixing drums of different heights. It has good practicality. When adding, it can be selected according to the state of adding anti-rutting agent. When adding solid anti-rutting agent, it is put into the solid material box 4, and the first motor 5 is started. Under the transmission of the coupling, the spiral conveying rod 6 rotates synchronously, and the rotation of the spiral conveying rod 6 can spirally convey the solid anti-rutting agent, thereby avoiding clogging of the solid anti-rutting agent during addition. At the same time, when the first motor 5 rotates at a uniform speed, the amount of solid anti-rutting agent passing through per unit time is fixed, so it is only necessary to change the rotation time of the first motor 5 to accurately control the addition amount of the solid anti-rutting agent and improve the accuracy of addition. When the liquid anti-rutting agent is added, it is added to the inside of the liquid material barrel 8. At this time, the weighing sensor 9 can weigh the weight of the liquid material barrel, and the weighing sensor 9 will transmit the weighing data to the PLC controller 3. The user can pre-set the required value. When the value is reached, the PLC controller 3 will start the solenoid valve 10. After the solenoid valve 10 is started, the infusion tube 11 will be opened, so that the liquid anti-rutting agent can be added to the asphalt mixing barrel. By adding solid and liquid anti-rutting agents, the scope of application is effectively increased, and the practicality is good.
