[0002] A slurry sealer is a type of mechanical equipment specifically used for road maintenance and construction, primarily for slurry seal treatment of road surfaces. Slurry seal is a preventive pavement maintenance technology that involves mixing a certain ratio of cement, emulsified asphalt, water, aggregate (such as fine sand), additives, and other materials into a slurry through a stirring mechanism, which is then evenly spread and compacted on the road surface, thereby forming a thin and dense protective layer. Existing stirring mechanisms generally include a silo, a stirring screw disposed in the silo, a drive member for driving the stirring screw to rotate, and a discharge port disposed in the silo; however, given that the stirring screw cannot fully mix all the materials in the silo, in order to ensure sufficient stirring, the stirring screw needs to be set longer, which reduces the available space of the vehicle body.

Detailed Description of the Specific Embodiment

[0023] The utility model provides a stirring mechanism for a slurry sealing vehicle. To make the purpose, technical solution and effect of the utility model clearer and more definite, the following takes examples with reference to the drawings to further elaborate on the utility model in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0024] Please refer to Figure 1The utility model provides a stirring mechanism for a slurry sealing vehicle, comprising a silo 1, a stirring screw 3 extending along the length direction of the silo 1, a driving member 4 which is transmission-connected to one end of the stirring screw 3 and located outside the silo 1, and a feeding port 11 and a discharging port 12 arranged on the silo 1; the silo 1 is also provided with a stirring shaft 2 extending along its length direction, one end of the stirring shaft 2 passes through the side wall of the silo 1 and is transmission-connected to the driving member 4; the stirring shaft 2 is located above the stirring screw 3; the driving member 4 is used to drive the stirring screw 3 and the stirring shaft 2 to rotate synchronously.

[0025] In actual use, the material to be mixed is fed into the silo 1 through the feed port 11. The driving member 4 drives the stirring shaft 2 and the stirring screw 3 to rotate synchronously. Therefore, the free-falling material first contacts the stirring shaft 2 and is stirred for the first time by the stirring shaft 2. Then, the stirring screw 3 stirs the material for the second time while the material is being transported. The setting of the stirring shaft 2 can achieve both the dispersion and preliminary mixing of the materials, thereby reducing the requirements of the stirring screw 3 for the uniform mixing of the materials, thereby shortening the length of the stirring screw 3 and reducing the overall volume of the stirring mechanism.

[0026] See also Figure 1 and Figure 2 In some embodiments, the driving member 4 includes a driving motor 41, a reducer 42 connected to the output end of the driving motor 41, a transmission shaft connected to the reducer 42, a coupling for connecting the transmission shaft and the outer end of the stirring screw 3, a first driving wheel 43 provided on the transmission shaft, a first driven wheel 44 provided on the outer end of the stirring shaft 2, and a first synchronous belt 45 wound between the first driving wheel 43 and the first driven wheel 44. Specifically, when the driving motor 41 is running, it drives the transmission shaft, the coupling, and the stirring screw 3 to rotate. At the same time, the stirring shaft 2 is also synchronously rotated by utilizing the arrangement of the first driving wheel 43, the first driven wheel 44, and the first synchronous belt 45. The above arrangement achieves synchronous rotation of the stirring shaft 2 and the stirring screw 3 through a single driving member 4, which can reduce the number of driving members 4 and help reduce manufacturing costs.

The above structure utilizes the second driving wheel 46, the second driven wheel and the second synchronous belt 47 to realize the synchronous rotation of the two stirring screws 3. This structure combined with the stirring shaft 2 realizes the synchronous rotation of three rod bodies driven by one driving member 4.
