Description

Technical Field

[0001] This utility model belongs to the technical field of dynamic detection devices, and more specifically, it relates to a dynamic detection device for the dryness and wetness of cement concrete in a mixing plant. Background Technology

[0002] Cement concrete, as the most widely used and essential building material in engineering construction, directly determines the core performance indicators of subsequent engineering structures, such as strength, durability, and impermeability, based on its mixing quality. The wet-dryness ratio of concrete is a key parameter for controlling mixing quality. An excessively high water-cement ratio leads to reduced concrete strength and an increased risk of shrinkage cracking, while an excessively low ratio results in poor flowability, honeycomb-like surface defects, and even structural load-bearing safety hazards. Therefore, a dynamic monitoring device is needed in the mixing plant production process to facilitate accurate and real-time control of the concrete's wet-dryness ratio.

[0003] Based on existing technology, current dynamic detection devices for the dryness and wetness of cement concrete mainly rely on operators to observe the appearance of the concrete mixture and the built-in sensors for detection. However, in a closed mixing space, operators cannot directly observe the state of the concrete mixture. Furthermore, the built-in sensors are easily damaged by the mixing blades and grinding materials, causing damage to the detection structure and affecting its normal detection of the dryness and wetness of cement concrete. Utility Model Content

This device solves the problem that in a closed mixing space, operators cannot directly observe and process the state of the concrete mixture, and the built-in sensor is easily damaged by the mixing blades and grinding materials, affecting its normal detection and processing of the dryness and wetness of cement concrete.

[0005] This utility model provides a dynamic detection device for the dryness and wetness of cement concrete in a mixing plant, which is achieved by the following specific technical means: A dynamic detection device for the wet and dry properties of cement concrete in a mixing plant includes: a mixing body; a bottom mounting through hole at the bottom of the mixing body; two fixed connection through holes at the bottom of the mixing body; an inner frame connected to the internal thread of the bottom mounting through hole; a locking nut connected to the external thread of the inner frame; a mating groove at the top of the inner frame; detection sensors fixedly connected to the inside of the two fixed connection through holes; a built-in sensor at the top of the inner frame; a central connecting rod inside the mixing body; a splicing groove at the top of the central connecting rod; internal seepage through holes equidistantly opened on the outer wall of the central connecting rod; and four circumferentially distributed mixing blades fixedly connected to the outer wall of the central connecting rod.

The built-in sensor is threadedly connected to the inner bracket via an inner connector and a mating groove, forming a nested protective structure with the cylindrical groove of the middle connecting rod.

Furthermore, the directional seepage design of the internal seepage holes ensures stable contact between the sensor and the concrete slurry. The built-in sensor is fitted inside the middle connecting rod, and the internal seepage holes on the outer wall of the middle connecting rod allow the concrete slurry during the mixing process to directly contact the sensor.
