[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1-Figure 4A vibrating mixing device for asphalt mixture comprises a body 1, the body 1 comprises a mixing pot 11 mounted on a bracket 12 for stirring asphalt mixture, a stirring blade for stirring is arranged above the mixing pot 11, a driving assembly 2 for controlling the movement of the mixing pot 11 is arranged on the bracket 12, the driving assembly 2 comprises a displacement member 22, a limit member 25, and a rotating member 23, a connecting ring 24 is fixedly mounted on the mixing pot 11, the displacement member 22 comprises a first motor 221, a first connecting block 222, a second connecting block 223, and a bearing 224, the first motor 221 is fixedly mounted on the bracket 12, the output end of the first motor 221 is fixedly connected to one end of a rotating column 21, the first connecting block 222 is fixedly mounted on the connecting ring 24, the rotating column 21 is threadedly connected to the first connecting block 222, the second connecting block 223 is fixedly mounted on the connecting ring 24, the centers of the first connecting block 222, the second connecting block 223, and the connecting ring 24 are on the same straight line, and the bearing 224 The rotation is arranged on the outer shell of the machine body 1, and a prismatic connecting groove 2241 is arranged at the center of the bearing 224. The second connecting block 223 is adapted to the shape of the connecting groove 2241, and the second connecting block 223 is slidably connected to the connecting groove 2241. The axis of the bearing 224 coincides with the axis of the rotating column 21, so that the mixing pot can rotate along the axial direction of the rotating column 21. The limiter 25 is used to limit the rotation of the bearing 224, and the bearing 224 cannot rotate. The first motor 221 drives the rotating column 21 to rotate, so that the mixing pot 11 can reciprocate along the long side direction of the rotating column 21, so that the raw materials in the mixing pot 11 are shaken, and then cooperated with the stirring blade of the machine body 1, so that the stirring blade can mix and stir the raw materials at the edge position and the raw materials at the middle position in the mixing pot 11, so that the raw materials in the mixing pot 11 are mixed more evenly to a certain extent. The rotating member 23 is used to make the mixing pot 11 rotate along the axial direction of the rotating column 21, so as to facilitate the pouring out of the mixed asphalt mixture in the mixing pot 11.

[0021] Reference Figure 2-Figure 5The limiting member 25 includes a mounting block 251, a limiting block 252, and a spring 253. The mounting block 251 is fixedly connected to the corresponding position of the shell of the body 1. The bearing 224 is rotatably mounted on the mounting block 251. The mounting block 251 is provided with a mounting groove 2511. The mounting groove 2511 and the connecting groove 2241 have the same vertical cross-section size and shape. The limiting block 252 is slidably fitted with the corresponding positions of the mounting groove 2511 and the connecting groove 2241. The spring 253 is arranged in the mounting groove 2511 away from the side of the second connecting block 223. When the spring 253 is in the initial state, the limiting block 252 is located at the connecting position of the mounting groove 2511 and the connecting groove 2241, so that the bearing 224 cannot rotate. The rotating member 23 includes a push block 231. The push block 231 The first motor 221 drives the rotating column 21 to rotate, and the mixing pot 11 moves in the direction away from the first motor 221. The second connecting block 223 moves in the connecting groove 2241 toward the limiting block 252. As the second connecting block 223 moves, the pushing block 231 abuts against the limiting block 252, and the spring 253 contracts under pressure. When the spring 253 contracts to the limit, the limiting block 252 moves into the mounting groove 2511, and the second connecting block 223 is located in the connecting groove 2241. At this time, the bearing 224 is not limited, and the first motor 221 continues to rotate, driving the bearing 224 to rotate. The pushing block 231 rotates at the same time, so that the mixing pot 11 rotates to pour out the mixed asphalt mixture.

[0022] Reference Figure 1-Figure 3 A vibration motor 3 is fixedly installed on the bottom surface of the mixing pot 11. When the stirring blades stir the raw materials in the mixing pot 11, the vibration motor 3 drives the pot body to vibrate synchronously. The vibration wave applies an exciting force to the asphalt mixture, so that the asphalt vibrates to reduce viscosity during the mixing process, increases fluidity, and makes the distribution of powder and asphalt more uniform, thereby improving the mixing efficiency, improving the quality of the asphalt mixture, and reducing the total carbon emissions. To a certain extent, the various raw materials in the mixing pot 11 are mixed and distributed more evenly.

[0023] Reference Figure 1-Figure 3 A first controller 4 for controlling the vibration frequency of the vibration motor 3 is installed on the machine body 1. The first controller 4 is electrically connected to the vibration motor 3, and can realize the working conditions of applying different vibration parameters (vibration frequency, vibration amplitude, vibration time). A second controller 5 for controlling the rotation speed and direction of the first motor 221 is installed on the machine body 1. The second controller 5 is electrically connected to the first motor 221. When mixing the raw materials in the mixing pot 11, the first motor 221 is controlled to rotate forward and reverse so that the mixing pot 11 can reciprocate along the long side direction of the rotating column 21, and the various raw materials in the mixing pot 11 are shaken. After the asphalt mixture is evenly mixed, the first motor 221 is controlled to drive the rotating column 21 to rotate, so that the mixing pot 11 rotates and the asphalt mixture is poured out.

[0024] The working principle of the embodiment of the present application is as follows: when mixing asphalt mixture, various raw materials such as mineral powder, finer aggregate, coarse aggregate and asphalt are fed into the mixing pot 11, the stirring blade is started, and then the first motor 221 is controlled by the second controller 5 to rotate forward and reversely so that the mixing pot 11 can reciprocate along the long side direction of the rotating column 21, and at the same time, the vibration motor 3 is controlled by the first controller 4 to vibrate to mix the raw materials in the mixing pot 11. After the mixing is completed, the vibration motor 3 is controlled to be turned off by the first controller 4, and the second controller 5 controls the first motor 221 to continue to rotate so that the mixing pot 11 moves away from the first motor 2 21, the second connecting block 223 moves in the connecting groove 2241 toward the limit block 252. As the second connecting block 223 moves, the push block 231 abuts against the limit block 252, and the spring 253 contracts to the limit under pressure. At this time, the bearing 224 is not limited, and the first motor 221 continues to rotate. At this time, the bearing 224 rotates, the push block 231 rotates, and the mixing pot 11 rotates to pour out the mixed asphalt mixture, which makes the various raw materials in the mixing pot 11 more evenly mixed and distributed to a certain extent, and at the same time improves the mixing efficiency of the asphalt mixture in the mixing pot 11 to a certain extent.
