Description

Technical Field

[0001] The invention relates to the field of material analysis, in particular to a drilling sampling device for detecting building decoration materials. Background Art

[0002] Sampling of building decoration materials is the operation of extracting samples from part of the building decoration materials for testing. The sampling operation should be adapted to the purpose of sampling, the type of sampling control and the materials and products to be sampled. First, determine the coring point, clean the drill bit with clean water, drill a hole at the coring point, and ensure that there is no damage at the sampling point when sampling. Take out the drilled core block; send the core block to the laboratory for analysis, including strength, density, content and other indicators. When sampling building decoration materials, due to different materials, it is easy to cause damage to the location when sampling at the sampling point.

[0003] In response to the technical problems existing in the drilling sampling device for building decoration material detection mentioned above, it was found through searching that there is a patent number CN202010036141.4 for an online sampling and detection device for plates and its method. The online sampling and detection device for plates includes a first conveying mechanism, a second conveying mechanism, and a lifting and conveying mechanism installed above the second conveying mechanism. The first conveying mechanism and the second conveying mechanism are arranged in sequence along the transmission direction of the plate. The lifting and conveying mechanism includes a lifting mechanism and an inclined upper plate section. The upper plate section is arranged above the second conveying mechanism. The lifting mechanism is arranged to drive the upper plate section to be lowered to the first position so that the upper surface of the lower end of the upper plate section is lower than the bearing surface of the second conveying mechanism to receive the plate for detection. The lifting mechanism is also arranged to raise the upper plate section to the second position after the upper plate section receives the plate, so as to allow subsequent plates to continue to be normally conveyed through the second conveying mechanism. The online sampling and detection device for plates realizes automatic sampling of plates, improves the degree of automation of the device, reduces manual operation, and reduces the possibility of confusion in the conveying process.

[0004] The drilling sampling device is prone to slipping at the sampling point during the sampling process due to the different materials of different plates, causing the sampling point position to shift, resulting in poor sampling quality at the sampling point and an unstable environment for multiple material sampling. At the same time, a large amount of dust will be generated when drilling during the sampling process, and the dust is easy to splash onto the sampled material. After multiple processing, it is easy to cause the material components to mix, and the environment needs to be cleaned after processing, which is more troublesome. Summary of the invention
