[0028] More specifically:

[0029] like Figure 1-Figure 5 As shown:

[0030] A heating assembly 3 is installed inside the regeneration agent holding box body 1, and the heating assembly 3 includes a U-shaped plate 301 fixed on the upper surface of the regeneration agent holding box body 1, a servo motor 302 installed on the upper surface of the U-shaped plate 301 by bolts, and a rotating rod 1 305 arranged at the output end of the servo motor 302, the surface of the rotating rod 1 305 is rotatably connected to the U-shaped plate 301 through a bearing, a rotating rod 2 306 is arranged at the other end of the rotating rod 1 305, and a rotating disk 307 is fixed at the other end of the rotating rod 2 306, and the rotating disk 307 is rotatably connected to the regeneration agent holding box body 1 through a bearing, and a plurality of groups of frames 308 arranged equidistantly in a ring are fixedly arranged inside the rotating disk 307, and a heating rod 309 is arranged on the frame 308;

[0031] A gear 1 303 is fixed to the output end of the servo motor 302 , a gear 2 304 is meshedly connected to the surface of the gear 1 303 , and a rotating rod 1 305 is fixedly connected to the gear 2 304 .

[0032] In the present embodiment: the regeneration agent spraying device for factory-mixed hot-regenerated asphalt mixture, when in use, after the old asphalt mixture is added into the regeneration agent containing box body 1 through the feed port (not shown in the figure), the servo motor 302 is then started, thereby driving gear one 303 to rotate, and since gear one 303 and gear two 304 are meshingly connected, gear two 304 is driven to rotate, and through the rotation of gear two 304, the rotating rod one 305 is driven to rotate, and the rotating rod one 305 drives the rotating rod two 306, the rotating disk 307 and the frame 308 to rotate synchronously, and the heating rod 309 is driven to rotate through the frame 308. Through this operation, mobile heating operation can be realized, so that the heating is more uniform, the asphalt melting efficiency is improved, thereby improving work efficiency, and the use effect is better, meeting the actual use needs. At the same time, with the rotation of the heating rod 309, the melted old asphalt and the regeneration agent can be stirred to improve the fusion effect.

[0033] Going further;

[0034] In an optional embodiment, symmetrically arranged limit rods 312 are fixed inside the frame 308, a slider 310 is slidably connected between the two groups of limit rods 312, the heating rod 309 and the slider 310 are fixedly connected, a strong spring 311 is wound around the surface of the limit rod 312, and the two ends of the strong spring 311 are respectively fixedly connected to the slider 310 and the frame 308, a rope 313 is fixed to the surface of the slider 310, a connecting disk 315 is provided above the rotating disk 307, and symmetrically arranged electric push rods 316 are installed between the connecting disk 315 and the rotating disk 307, and one end of the rope 313 passes through the rotating disk 307 and is fixedly connected to the connecting disk 315.

[0035] In this embodiment: the electric push rod 316 is started, which in turn drives the connecting disk 315 to move upward. The connecting disk 315 moves upward and the rope 313 is pulled. The slider 310 is moved through the rope 313, so that the slider 310 slides on the limit rod 312, and the strong spring 311 is stretched at the same time. The movement of the slider 310 can drive the heating rod 309 to move. The lateral movement of the heating rod 309 can further improve the uniformity of heating and improve the asphalt melting efficiency.

[0036] Going further;

The roller 314 is rotatably connected to the rotating disk 307 via a rotating shaft, and the rope 313 is wound around the surface of the roller 314 .

[0038] In this embodiment, the rope 313 slides on the roller 314 , and the roller 314 can reduce the friction between the rope 313 and the rotating disk 307 , thereby improving the smoothness of the movement of the rope 313 .

[0039] Further,

[0040] In an optional embodiment, an auxiliary component 4 is installed between the first rotating rod 305 and the second rotating rod 306, and the auxiliary component 4 includes a locking block 401 fixed to one end of the first rotating rod 305, a locking sleeve 402 sleeved on the locking block 401, and a fixed disk 403 fixed to the surface of the second rotating rod 306, and a compression spring 405 is fixed between the fixing disk 403 and the locking sleeve 402, and the compression spring 405 is wound around the surface of the second rotating rod 306;

[0041] Telescopic tubes 404 equidistantly arranged in a ring shape are fixed between the locking sleeve 402 and the fixing plate 403 .

[0042] In this embodiment: when the frame 308 is located at the feed port of the regeneration agent holding box body 1, in order not to affect the feeding operation, the frame 308 needs to be staggered from the feed port, by pressing the lock sleeve 402, the lock sleeve 402 moves down, so that the lock sleeve 402 is separated from the lock block 401, and the compression spring 405 and the telescopic tube 404 are compressed at the same time. Through the setting of the compression spring 405, the rebound of the compression spring 405 can make the lock sleeve 402 and the lock block 401 fit tightly, and through the setting of the telescopic tube 404, the lock sleeve 402 and the fixed plate 403 can be increased. The connection stability is ensured by rotating the lock sleeve 402, thereby driving the second rotating rod 306 to rotate, and the second rotating rod 306 drives the rotating disk 307, the frame 308 and the heating rod 309 to rotate synchronously. Therefore, through this operation, the frame 308 and the feed port can be quickly and conveniently dislocated without intermittently starting and stopping the servo motor 302, thereby protecting the servo motor 302. At the same time, when the servo motor 302 is temporarily damaged, the heating rod 309 can be manually driven to achieve the rotation effect, thereby further improving the use effect of the device and improving the flexibility and practicality of the device.

[0043] The working principle and use process of the utility model are as follows: the regeneration agent spraying device for factory-mixed hot regenerated asphalt mixture, when in use, after the old asphalt mixture is added into the regeneration agent containing box body 1 through the feed port (not shown in the figure), the servo motor 302 is then started, thereby driving the gear 1 303 to rotate, and since the gear 1 303 and the gear 2 304 are meshingly connected, the gear 2 304 is driven to rotate, and the rotation of the gear 2 304 drives the rotating rod 1 305 to rotate, and the rotating rod 2 306, the rotating disk 307 and the frame 308 are driven to rotate synchronously through the rotating rod 1 305, and the heating rod 309 is driven to rotate through the frame 308. Through this operation, the mobile heating Thermal operation makes heating more uniform, improves asphalt melting efficiency, thereby improving work efficiency and achieving better use effects to meet actual use needs. At the same time, as the heating rod 309 rotates, the melted old asphalt and the regeneration agent can be stirred to improve the fusion effect. At the same time, the electric push rod 316 is started to drive the connecting disk 315 to move upward. By moving the connecting disk 315 upward and pulling the rope 313, the slider 310 is moved by the rope 313, so that the slider 310 slides on the limit rod 312, and at the same time, the strong spring 311 is stretched. The movement of the slider 310 can drive the heating rod 309 to move, and the lateral movement of the heating rod 309 , thereby further improving the uniformity of heating and the asphalt melting efficiency, and the rope 313 slides on the roller 314, and the roller 314 can reduce the friction between the rope 313 and the rotating disk 307, thereby improving the smoothness of the movement of the rope 313. When the frame 308 is located at the feed port of the regeneration agent holding box body 1, in order not to affect the feeding operation, the frame 308 needs to be staggered from the feed port, by pressing the lock sleeve 402, the lock sleeve 402 moves down at this time, so that the lock sleeve 402 is disengaged from the lock block 401, and at the same time, the compression spring 405 and the telescopic tube 404 are compressed. By setting the compression spring 405, the rebound of the compression spring 405 can separate the lock sleeve 402 from the lock block 4 01 fits tightly, and at the same time, the setting of the telescopic tube 404 can increase the connection stability of the locking sleeve 402 and the fixed disk 403. By rotating the locking sleeve 402, the rotating rod 306 is driven to rotate, and the rotating disk 307, the frame 308 and the heating rod 309 are driven to rotate synchronously through the rotating rod 306. Therefore, through this operation, the frame 308 and the feed port can be dislocated quickly and conveniently without intermittently starting and stopping the servo motor 302, thereby protecting the servo motor 302. At the same time, when the servo motor 302 is temporarily damaged, the heating rod 309 can be manually driven to achieve the rotation effect, thereby further improving the use effect of the device and improving the flexibility and practicality of the device.
