Concrete mixture volume weight detection device

Abstract

The invention relates to the technical field of building material detection, and relates to a concrete mixture volume weight detection device. The device comprises a base and a detection outer cylinder mounted in the middle of the top, a control unit connected with the liquid crystal display screen and the broadcaster is arranged in the base; a rack is mounted at front end of base, a cover plate is mounted at the top of the detection outer cylinder; a feeding pipe is fixedly mounted at the top of the cover plate; horn hoppers which are integrally formed are arranged at the tops of the feedingpipes; a middle cross frame is welded in the middle in the feeding pipe; a stirring rod is welded in the middle of the bottom of the middle crossarm; the inner diameter of the capacity cylinder is greater than the outer diameter of the feeding pipe; a weighing sensor is mounted at the bottom of the capacity cylinder; a linkage mechanism is arranged at the bottom of the detection outer cylinder; and a drive device matching the linkage mechanism is arranged in the base. According to the present invention, a plurality of concrete samples can be detected at a time, the working efficiency is high,and the concrete samples in the volume cylinder are horizontal and uniform through the stirring rod and the volume cylinder moving relatively, such that the volume value of the concrete mixture in thevolume cylinder can be conveniently and accurately measured.

Description

technical field [0001] The invention relates to the technical field of building material detection, in particular to a concrete mixture bulk density detection device. Background technique [0002] Test density is also called gravity. There are two understandings: 1. It refers to the weight of an object within a unit volume. It is often used in engineering to refer to the weight of a cubic meter, such as the weight of a unit volume of soil. 2. Indicates the gravitational characteristics of an object due to the gravitational force of the earth. For homogeneous fluids, it refers to the gravitational force acting on a unit volume. [0003] Bulk density is one of the most basic performance indicators of concrete mixture. Under the condition of a certain concrete mix ratio, the bulk density directly reflects the compactness of the concrete material, and the bulk density plays a decisive role in the mechanical properties, long-term performance and durability of concrete.

Problems solved by technology

As we all know, to calculate the bulk density of concrete mixture, two values ​​need to be known, that is, the weight and volume of concrete mixture. When one of the values ​​is inaccurate, it is difficult to calculate the accurate bulk density value. In the prior art, measuring concrete The device structure of the mixture is relatively simple, the function is single, and the efficiency is low. It cannot detect different batches of samples at one time, which has limitations.
