Abstract

The invention provides a sampler and a sampling system to solve the problem of large coal quality analysis result error caused by manual sampling in the prior art. The sampler comprises an openmouthed barrel body, a movable turnover plate, a weight sensor and a control assembly, wherein the movable turnover plate is disposed at the open mouth, and is used for opening or closing or the open mouth; the weight sensor is used for acquiring the weight of a sample placed on the movable turnover plate; the movable turnover plate and the weight sensor are respectively connected with the control assembly; if the weight of the sample reaches a standard weight, the control assembly controls the movable turnover plate to open the open mouth in order to make the sample enter the barrel body; and if the weight of the sample does not reach the standard weight, the movable turnover plate keeps the open mouth sealed.

Description

technical field [0001] The invention relates to the technical field of sampling, in particular to a sampler and a sampling system. Background technique [0002] As is well known to those skilled in the field of mineral powder and coal sampling technology, to know the quality analysis results of mineral powder and coal, it generally needs to go through three steps: sampling, sample preparation, and testing. The source of errors in quality analysis results is for this The process of three stages. From a statistical point of view, if the variance is used to represent the error of the quality analysis result, the analysis result is: in the total error of the coal quality analysis results of ore powder and coal, 80% of the error comes from the sampling process, and 16% of the error It comes from the sample preparation process, of which only 4% of the error comes from the laboratory test process. It can be seen that collecting representative coal samples is an important basis fo...
