Problems solved by technology

[0003] During the production process of concrete, the powder needs to be sampled. After the sampling is completed, multiple tests are required. The existing technology usually takes out a large amount of powder at one time, and then divides it artificially, and then does the test again. The workload is heavy and it is inconvenient to use. ; Now provide a kind of powder sampling equipment in concrete production to solve the above technical problems

Abstract

The invention discloses powder sampling equipment in concrete production, and relates to the technical field of concrete. The equipment comprises an equipment body, a material suction part which is arranged on the equipment body and is used for sucking powder into the equipment body, a dust falling part which is arranged in the equipment body and is used for preventing a discharged sample from floating in the air, and a quantifying piece which is fixedly arranged at the bottom of the equipment body, and internal cavities of the quantifying piece and the equipment body are communicated; a discharging cavity is formed in the quantifying piece; a rotating shaft is rotationally arranged in the center of the discharging cavity; a plurality of blades are arranged on the rotating shaft in an array mode; one blade abuts against an elastically-arranged quantifying abutting piece, and a quantifying cavity is defined by the blade and the adjacent blade; and a discharging opening is further formedin the bottom of the quantifying piece. By arranging the dust falling part, discharged samples are prevented from floating in the air, and powder is saved; and meanwhile, quantitative discharging isrealized.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to powder sampling equipment in concrete production. Background technique [0002] Concrete is currently the most widely used artificially prepared building material in the world. With the continuous development of the economy, my country's construction industry has developed rapidly, and the amount of infrastructure construction has continued unabated. As one of the most used building materials in modern construction projects, the demand for concrete has increased by leaps and bounds. In particular, super high-rise buildings require high-performance concrete, such as ultra-high pumpability, high-strength performance, and self-compacting properties. A large number of small tests and multiple pilot tests are required to design a concrete mix that meets the requirements. . [0003] During the production process of concrete, the powder needs to be sampled. After the sampling is comp...
