The waterproof anti-cracking dry-mixed mortar is used as each important branch in the dry-mixed mortar industry, is applied to various waterproof and impervious projects for decades, and has a plurality of achievements, but has a plurality of problems. Studies have shown that: most waterproof and anti-crack mortars incorporate a polymeric component. The addition of the polymer component can obviously improve the main defects of the mortar, improve the workability, tensile strength, bonding strength, crack resistance and waterproof impermeability and reduce the brittleness of the mortar. On the other hand, the incorporation of the polymer induces a large amount of bubbles in the mortar, so that the porosity of the mortar is greatly increased, thereby greatly increasing shrinkage of the mortar, seriously decreasing strength and durability, and increasing with the increase of the incorporation amount of the polymer. Therefore, the total amount of the polymer added is not as high as possible, and the ratio between the total amount of the polymer added and the dry-mixed mortar main should be maintained at a proper level. In addition, the prior art can meet the requirements of dry-mixed mortar on water resistance, impermeability, crack resistance, durability and the like in terms of shrinkage reduction, strength improvement, compactness increase and the like, and can solve the problems of cracking, hollowing, falling-off and the like of the existing wall materials. The concrete steps are as follows: the micro-expansion component is added, so that the shrinkage rate of the mortar is reduced, and cracking is prevented; hydrophobic components are added, so that the workability is improved, the bleeding rate is reduced, and the strength and the impermeability are improved; the anti-cracking and anti-toughness components are added, the toughness of the mortar is increased, and the cracking resistance is improved.

In the prior art, the auxiliary materials are sequentially added into the mixing equipment or added into the mixing equipment simultaneously, so that the auxiliary materials need longer stirring time if the auxiliary materials are uniformly dispersed in the dry-mixed mortar main material to be in a finished product state. In each stirring process, off-line detection is needed to determine whether the stirred dry-mixed mortar reaches a finished product state, and whether the stirring requirement is met can be judged. In the prior equipment, a special sampling position is not necessarily arranged on the stirring equipment; for the off-line detection of sampling on stirring equipment without a special sampling position, errors caused by different relative states of materials due to different sampling positions of two times can exist; for the stirring equipment with a special sampling position, the sampling position can be used for storing the materials which are blocked at the sampling position by the last stirring, and the samples collected for the previous times need to be sampled for multiple times and discarded, so that the samples which are more accurate in reality can be obtained.
