AI Technical Summary
The existing sand moisture content analyzer has a fixed length for its downward probe structure, which is difficult to adapt to the uneven stacking and large differences in the amount of sand at the construction site. This results in the detection depth being non-adjustable, affecting the representativeness and accuracy of the test data, increasing the possibility of repeated testing, and reducing work efficiency.
An adjustable-depth sand moisture content detector was designed. The lowering and raising of the probe rod is achieved through a sliding groove on the mounting frame and a first motor-driven gear system. It is equipped with a cleaning component and a high-pressure air pump to assist in cleaning, ensuring detection accuracy and equipment stability.
It enables flexible adjustment of the detection depth according to the on-site conditions, improves the representativeness and accuracy of the detection data, reduces the possibility of repeated detection, and enhances work efficiency and equipment adaptability.
