Description

Negative pressure type concentrate sampling device Technical Field The utility model relates to the technical field of mineral detection equipment, in particular to a negative pressure type concentrate sampling device. Background With the development of technology, the content detection of components is needed for concentrate powder and trace element powder required by metal smelting and other industries, the sampling result can directly influence the production quality of products and the economic benefit of trade settlement, at present, sampling is mainly carried out by manually inserting a sample drill into the mineral powder of a carriage, the sampling depth is insufficient, the sampling is not full-section sampling, the representativeness of the sample is insufficient, the sample drill is clamped by a mechanical arm to be inserted into the mineral powder for sampling, the cost of the mechanical arm is high, the depth of the mineral powder is not easy to detect, the inserting depth of the sample drill can not exactly touch the carriage, a controller can delay the control of the pressure sensor, the sample drill can easily damage the bottom surface of the carriage, the sample drill is easy to block, the sample drill can be taken out by beating, the working environment is not influenced, the representativeness of the sampling is unstable due to many factors of manual intervention, even the occurrence of personal fraud is caused, the automatic sampling drill is only a simple circular tube, the sampling is easy to be blocked, the sampling can be taken out only by beating, and the sampling efficiency is influenced and the working environment is destroyed. Disclosure of utility model The utility model aims to solve the problems in the background art, and provides a negative pressure type concentrate sampling device.
