Abstract

Technical Field
[0001] The utility model relates to the technical field of sample sampling, in particular to a steel bar pneumatic sample sampling device. Background Art
[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. Rebar is a building material frequently used in the construction field. Its quality is related to the quality and reliability of the building. Bending and shearing properties are one of the main indicators of rebar quality.
[0003] At present, when testing the quality of steel bars, 6 samples are sent for inspection for each batch. The test items include 6 weight deviation tests, 3 mechanical property tests, and 3 bending tests. Since the laboratory is not at the production site, the samples need to be sent to the physical laboratory by the on-site inspection personnel through the pneumatic conveying system. When unloading the samples, the laboratory operators need to bend down to completely remove the sample tube, and then open the tube cover to pour out the samples for testing. According to the requirements of the weight deviation test in the national standard, the length of the sample sent for inspection must be greater than 500㎜, resulting in a large sample weight. The net weight of the sample tube is 5.2㎏. Calculated based on the sample of φ20㎜, each tube can hold 3 samples. The weight of the sample carried by the sample tube is about 10㎏. Each batch is sent for inspection in two tubes, and there are about 60 batches per shift. Under normal operation, the operator's handling volume per shift is as high as 1.2 tons, which is too labor-intensive. Utility Model Content
