AI Technical Summary

Technical Problem

When the coal-based solid waste area is large, sampling by area requires taking multiple sample containers one by one, which is inconvenient to carry and poses a risk of cross-contamination of samples, affecting the accuracy of data and sampling efficiency.

Method used

Design a sampler for coal-based solid waste sampling, integrating multiple storage chambers and insertion slots. By cooperating with the rotation limiter and the insertion slot, the rotation switching of the storage structure can be realized, ensuring that the sample is collected in different areas and avoiding cross-contamination, thereby improving portability and sampling efficiency.

Benefits of technology

It enables efficient collection and storage of coal-based solid waste samples from different regions, avoids cross-contamination, ensures the accuracy and reliability of sampling data, and improves the convenience and efficiency of the sampler. It is particularly suitable for comparative analysis of coal-based solid waste over a large area or in multiple regions.

Abstract

This utility model provides a sampler for coal-based solid waste sampling, comprising: a sampling cylinder having an insertion hole and a feeding channel at the top; a storage structure having multiple storage chambers and multiple insertion slots corresponding to the storage chambers, the storage structure being disposed inside the sampling cylinder and rotatable to switch between the storage chambers below the feeding channel and the insertion slots below the insertion hole; and a rotation limiting member that can be inserted and removed through the insertion hole. When the end of the rotation limiting member extending into the sampling cylinder is inserted into the insertion slot corresponding to the insertion hole, the rotation of the storage structure is restricted; when the end of the rotation limiting member extending into the sampling cylinder is not inserted into the insertion slot corresponding to the insertion hole, the storage structure can rotate. The technical solution provided by this utility model solves the problem in the prior art where multiple sample containers need to be taken out one by one for sampling in different areas, which is inconvenient to carry.
