Description

Technical Field

In a coal analysis laboratory, an inspector needs to acquire a sample for analysis from a sample having a particle size of 0.2mm and a weight of about 100g per sample, and the weight of the sample for analysis is only 0.5g to 1.0g. In the prior art, a manual sampling mode is generally adopted, for example, a small spoon is used for taking out a required sample from a sample bottle and placing the sample into a balance for weighing, in order to ensure the representativeness of sampling, the sample is required to be shaken uniformly during sampling, and the same sample is required to be shaken uniformly for many times because the indexes of the assay are different, so that time and labor are wasted. With the development of intelligent assay systems, the manual sampling approach clearly fails to meet the current assay efficiency requirements.

To increase the efficiency of sampling, practitioners have devised mechanical sampling devices, such as CN201820440569.3 discloses an automated sample addition system comprising: a vibratory feeder for delivering a sample by means of continuous vibration and a sampling assembly for adding a metered amount of sample to the vibratory feeder; the vibratory feeder comprising: the vibration machine is connected with the guide chute and used for driving the guide chute to vibrate so as to convey the sample in the guide chute forwards; the sampling assembly comprises: a sample bottle assembly for holding a sample; and the sample spoon assembly is used for extending into the sample bottle assembly to take out the quantitative sample, and horizontally moving the sample bottle assembly to pour the taken quantitative sample into the guide chute. Although this kind of mechanical type sampling equipment compares artifical sample efficiency to improve to some extent, but powder sample in-process receives environmental impact easily, and the feeding mode is unreasonable, and vibration feeding leads to the powder to produce the granularity segregation easily, and when feeding and clearance, the powder flies upward and pollutes the environment easily and still causes the mixed appearance easily simultaneously, and above defect all can cause the test result inaccurate.
