Problems solved by technology

[0004] 1. A large amount of dust or fine particles will be generated during the crushing process, which will easily remain and adhere to the crushing tool and the inner wall of the crushing chamber, resulting in loss of samples, and is not conducive to disassembly and cleaning
[0005] 2. The degree of automation is not high, and it is often necessary to manually switch between retaining or discarding samples, and the labor intensity of feeding operations is high
[0006] 3. In the collection process of each blanking, the traditional technology does not design a sealing structure, which cannot achieve a better collection effect, which affects the subsequent measurement accuracy, and the generated dust also affects the environment.

Abstract

The invention discloses an automatic sample crusher. The automatic sample crusher comprises a frame, a control component, a powder making component, a feed hopper, a collecting channel, a discarding channel and a remaining channel, wherein the feed hopper is positioned at the feed end of the powder making component; the collecting channel is communicated with the discharge end of the powder making component; the discarding channel and the remaining channel are positioned at the discharge end of the collecting channel; a discharge pipe is arranged at the discharge end of the collecting channel, is positioned on a sample channel switching mechanism, and is driven by the sample channel switching mechanism to rotate to be communicated with the discarding channel or the remaining channel; a sealing component fitting the discarding channel or the remaining channel covers the discharge end of the discharge pipe; and the sealing component is connected with a sealing driving component, and is driven by the sealing driving component to move in the axial direction of the discharge pipe. The automatic sample crusher has such advantages as simple and compact structure, further improved sample crushing precision and reduced dust pollution.

Description

technical field [0001] The invention mainly relates to the field of sample preparation equipment, in particular to an automatic sample preparation pulverizer. Background technique [0002] In many technical fields of the prior art, it is necessary to make material samples. For example, in the field of coal sample testing, it is necessary to make a representative coal sample before performing various tests on the coal sample. In the production process, it is often necessary to crush the coal samples first and then collect them. During this period, there must be no loss of samples, and no physical or chemical changes in the samples, otherwise the final test results will be affected. [0003] In the sample preparation process, the automatic sample preparation pulverizer is often used, which uses a crushing tool to crush the materials fed from the hopper, and then directly introduces the crushed materials into a bottle for collection. . In this process, the following problems...
