Technical Field
[0001] This utility model relates to the field of cement-stabilized crushed stone, and in particular to a vibratory mixing device for cement-stabilized crushed stone. Background Technology
[0002] Cement-stabilized crushed stone is frequently used in road construction and other engineering projects. Before use, it needs to be thoroughly mixed to ensure its performance. The working principle of cement-stabilized crushed stone is as follows: it uses graded crushed stone as aggregate, with a certain amount of cementitious material and sufficient mortar volume to fill the voids in the aggregate, and is spread and compacted according to the interlocking principle. Its compaction degree is close to its density, and its strength mainly relies on the interlocking principle between the crushed stones. Simultaneously, sufficient mortar volume fills the voids in the aggregate, resulting in high initial strength, and its strength increases rapidly with age, quickly forming a slab-like structure. Therefore, it has high strength, good impermeability, and good frost resistance.
[0003] Most existing cement-stabilized crushed stone mixing devices rely solely on the rotation of a single mixing blade for mixing, resulting in poor mixing efficiency and uneven material mixing. Furthermore, the mixing process generates significant vibrations, which not only affect the stability and lifespan of the device but may also cause noise pollution.

[0020] The cylinder 6 is equipped with a stirring mechanism, which includes a drive chamber 61 installed at the end of the cylinder 6 and a stirring motor 62 located in the middle of one end face of the cylinder 6 and inside the drive chamber 61. The stirring motor 62 is fixed to the end of the cylinder 6 by a bracket. The output end of the stirring motor 62 is connected to a stirring shaft 63 extending to the center of the cylinder 6. Stirring blades 64 are fixed on the surface of the stirring shaft 63, and the two ends of the stirring shaft 63 are rotatably connected to the cylinder 6. A connecting shaft 65 is also provided in the middle of the outer end face of the drive chamber 61. The second baffle 5 is also set at an angle, and its inner side is rotatably connected to the outer end face of the drive chamber 61 through the connecting shaft 65. During operation, the stirring motor 62 drives the stirring shaft 63 to rotate, thereby driving the stirring blades 64 to stir the material.
[0021] like Figure 1-2 As shown, the mounting plate 3 is generally L-shaped and fits the top and rear edges of the base plate 1. The first baffle 4 is located near the lateral corner of the mounting plate 3. The mounting plate 3 and the first baffle 4 are generally F-shaped. The adjustment structure 10 is located between the lateral corner of the mounting plate 3 and the first baffle 4. The mounting plate 3 and the first baffle 4 achieve the effect of limiting the installation of the adjustment structure 10. The first baffle 4, in conjunction with the second baffle 5, facilitates the installation and limiting of the cylinder 6.

During the stirring process, the cylinder 6 can be rotated between the mounting plate 3 and the second baffle 5 under the drive of the adjustment structure 10.
