Background

At present, three mortar production modes are needed on domestic construction sites; the first type is a traditional manual stirrer, which is simple to operate, can stir out mortar only by more than three persons on site, the raw material weighing and proportioning control of the mortar is inaccurate, the mortar quality is not stirred out, the material is wasted, and the environment is greatly polluted by dust and noise. The second is that the wet-mixed mortar is intensively mixed by a mixing plant, and the amount of the mixed mortar is large; is not suitable for small-amount mortar. The mortar is quick to coagulate in high-temperature seasons and needs to be used up in a certain time, the mortar is single in variety, small in yield and high in cost. The third is premixed dry-mixed mortar, which is produced by professional manufacturers and needs to be built in an enterprise factory building. Drying sand, and mixing with cement, additive and other material in certain proportion. And delivering the mortar to a construction site by using a ready-mixed dry-mixed mortar vehicle, wherein the construction site needs to prepare and store a ready-mixed mortar tank and a stirrer, and when the mortar is used, the stirrer below the ready-mixed mortar tank is started, and water is added to start secondary stirring, so that the mortar is produced. The ready-mixed dry-mixed mortar has many defects, and the sand is wet and generates dust after being dried, wastes energy, pollutes the environment and increases economic cost. On the contrary, water needs to be added and stirred again to pollute the environment of the construction site. The most important is that the sand of the premixed dry-mixed mortar is dried, the water is added for secondary stirring in a short time, the sand in the mortar is not completely permeated by the water, the absorption and the drying are fast when the mortar is used, the wall needs to be maintained by adding water for a long time, and resources and manpower are wasted. The premixed dry-mixed mortar often has segregation phenomena, namely, the phenomena of sand generation, crack, hollowing and the like when the premixed dry-mixed mortar is painted on a wall after segregation, which belongs to chicken rib products. The three mortar production modes are more than 20-40% of the cost of the mortar produced by the environment-friendly mortar integrated production box, and the building cost is increased.

In addition, the sand transmission in the technical scheme is carried out by the auger, the principle of auger transmission is that the sand is transmitted forwards by extrusion, so that the acting force between the sand and the auger blade in the transmission process is large, the friction force between the sand and the auger blade is also large, and the auger blade is particularly seriously abraded due to the relative large hardness of the sand, so that the use cost is high, and the production is influenced by frequently replacing the auger blade; if the material of the auger blade is replaced by manganese steel, not only the cost is greatly increased, but also the service life is longer than before due to the unchanged conveying principle, the friction still exists, and the pressure between the sand and the auger blade is still larger, but the auger blade still needs to be replaced within a relatively short time. The transportation plate car is of a complete integrated structure in the last technical scheme, so that the overlong and the overlong can be avoided only by using the large-size transportation plate car in the turnover process from the factory to the use destination, the transportation cost is further higher, the transportation range of the large-size transportation plate car is also greatly limited, and more troubles can be caused in the transportation process.
