Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device for the mixing production of cement stabilized macadam base course. Background Technique

[0002] Principle of action of cement stabilized macadam: Cement stabilized macadam uses graded macadam as aggregate, adopts a certain amount of cementitious materials and sufficient mortar volume to fill the voids of the aggregate, and is paved and compacted according to the interlocking principle. Its compactness is close to the density, and the strength mainly depends on the interlocking principle between the macadams. At the same time, there is enough mortar volume to fill the voids of the aggregate. It has high initial strength, and the strength increases rapidly with age to form a plate body. Therefore, it has high strength, good impermeability and frost resistance. The cement dosage of cement stabilized macadam is generally 3% - 6% of the mixture, and the unconfined compressive strength for 7 days can reach 5.0 Mpa, which is higher than other subgrade materials. After the cement stabilized macadam is completed, it will not become muddy when encountering rain, and the surface is firm, which is an ideal base material for high-grade roads.

[0003] Currently, when mixing the cement stabilized macadam base course, a mixing device is needed. However, the existing mixing devices are often driven by motors. However, the motors of the existing mixing devices lack protection, so they can only be used in sunny environments. When used in rainy days, the motors may be damaged by moisture, seriously affecting the working efficiency and applicability of the mixing devices.

[0004] Therefore, a mixing device for the mixing production of cement stabilized macadam base course is proposed. Content of the Utility Model
