Automatic waste soil crushing device and intelligent material mixing method

Abstract

The invention relates to an automatic waste soil crushing device and an intelligent mixing method. The device comprises a stirrer, a conveying table and a control table, a feeding port is formed in one end of the conveying table, the other end of the conveying table communicates with the stirrer, a mixing port is formed in the middle of the conveying table, and a soil taking port is formed in the position, close to the bottom, of the stirrer; a soil moisture probe is installed in the feeding port, the soil moisture probe and the mixing port are communicated with a control table through wires, the control table obtains the volumetric water content, detected by the soil moisture probe, of the waste soil in time and calculates the mixing amount of an additive needing to be added, and the additive is added to the conveying table through the mixing port; a plurality of air pressure type soil crushing hammers are arranged at the top in the transportation table and used for beating the waste soil in the transportation process; the waste soil and an additive are further mixed in the stirrer and finally taken out through a soil taking opening; according to the invention, the integration of detection, soil crushing, material mixing and stirring can be realized, the waste soil treatment efficiency is improved, the construction period is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to an automatic waste soil crushing device and an intelligent mixing method, belonging to the field of engineering waste soil reuse. Background technique [0002] my country is undergoing large-scale engineering construction, such as urban construction projects, highways, railway projects, and subway construction projects. As long as the excavation and backfilling volumes of the project are different, various waste soils will inevitably be produced. Even if the excavation and filling volumes can be kept in balance, waste soils will still be produced due to the nature of the excavated soil or the difference in time and location between excavation and backfilling. [0003] For the waste soil with good engineering properties, it can be used in other projects by stacking, saving and turning over. In order to improve the properties of the soil, various admixtures are added before the waste soil is backfilled to improve the mechanical ...

AI Technical Summary

Problems solved by technology

In the reuse of waste soil in projects, certain admixtures are often mixed according to needs. However, the moisture content of soil in different locations of the same project is different. If a uniform admixture is used for treatment, it is difficult to achieve the desired effect. , to determine the moisture content of the waste soil at each location in the laboratory and then determine the amount of admixture, not only the workload is heavy, but the moisture content of the soil is constantly changing with the passage of time, so it is impossible to obtain an accurate moisture content

[0004] In addition, due to the large amount of waste soil and the large volume of a single piece of soil in the actual project, it is difficult for the traditional mixer to fully mix the admixture with the waste soil, and the uniformity is poor

If the mechanical properties of the waste soil cannot meet the expected requirements, or do not meet the corresponding requirements, a large amount of admixture needs to be added, which consumes a lot of manpower, material resources and financial resources
