[0033] See also Figure 1 , Figure 2 and Figure 4 The outer surface of the stirring tube 2 is fixedly connected with a plurality of stirring blades 3 arranged in a circle, the outer surface of the stirring tube 2 is fixedly connected with a plurality of high-pressure nozzles 4, the upper surface of the mixing barrel 1 is rotatably connected with a power shaft 12, the outer surface of the power shaft 12 and the top of the stirring tube 2 are fixedly connected with a pulley 13, the two pulleys 13 are connected by a belt transmission, and the setting of the pulley 13 and the belt can transmit power for the rotation of the stirring tube 2, the top of the power shaft 12 is fixedly connected to the output end of the external motor, and the setting of the external motor can provide power for the rotation of the power shaft 12.

[0034] See also Figure 1 , Figure 2 and Figure 3The outer surface of the stirring tube 2 is rotatably connected to two connecting plates 5 through a one-way valve bearing, and the outer surfaces of the two connecting plates 5 are fixedly connected to three supporting frames 6. Each supporting frame 6 is fixedly connected to a pressure box 7 on the side away from the stirring tube 2. Each pressure box 7 is provided with a scraping block 8 on the side away from the stirring tube 2, and each scraping block 8 is in contact with the inner wall of the mixing barrel 1.

[0035] See also Figure 1 , Figure 2 and Figure 4 A plurality of pressure rods 17 are inserted into the side of each pressure box 7 away from the stirring tube 2, and one end of each pressure rod 17 away from the stirring tube 2 is fixedly connected to the scraper block 8 close to it, and one end of each pressure rod 17 close to the stirring tube 2 is fixedly connected to a spring 18, and the other end of each spring 18 is fixedly connected to the inner wall of the pressure box 7 close to it. Through the setting of the spring 18, the purpose of close contact between the scraper block 8 and the inner wall of the mixing barrel 1 can be achieved. The bottom of the mixing barrel 1 is fixedly connected to a discharge pipe 15, and a valve 16 is installed inside the discharge pipe 15. Through the setting of the discharge pipe 15 and the valve 16, it is convenient for users to unload.

[0036] A road asphalt cold regeneration device in the present embodiment can achieve the purpose of mixing and stirring materials through the provided stirring tube 2 and stirring blades 3. Through the provided one-way bearing, the connecting plate 5 can be in an active state during the clockwise rotation of the stirring tube 2, thereby preventing the scraper block 8 from scraping the inner wall of the mixing barrel 1 during the stirring of the materials, effectively reducing the wear of the scraper block 8.

[0038] The working principle of the above embodiment is as follows: when in use, by starting the external motor to drive the stirring tube 2 to rotate clockwise, the stirring blade 3 can be driven to rotate to mix the materials inside the mixing barrel 1. The one-way bearing is in an active state and cannot drive the support frame 6 and the scraper block 8 to rotate. When the materials are mixed, the valve 16 is opened to discharge the materials. After the unloading is completed, when the stirring tube 2 is reversed, the one-way bearing is in a locked state, driving the support frame 6, the pressure box 7 and the scraper block 8 to rotate, and the materials on the inner wall of the mixing barrel 1 are scraped by the scraper block 8. The spring 18 is set so that the scraper block 8 can continue to be in close contact with the inner wall of the mixing barrel 1 under the action of the spring 18 after being worn, thereby extending the service life of the scraper block 8 and ensuring the scraping effect. During the scraping process, the water source is output by driving the external water pump to be sprayed from the high-pressure nozzle 4 through the connecting pipe 10 and the stirring tube 2, so as to clean the inner wall of the mixing barrel 1, thereby effectively reducing the labor intensity of the workers.
