Sample preparation crusher capable of automatically feeding

Abstract

The invention discloses a sample preparation crusher capable of automatically feeding. The sample preparation crusher capable of automatically feeding comprises a feeding base (1), a feeding bin (2),a material conveying device (3), a feeding shield (4), a crushing cavity (5), a material receiving drawer (6), a machine body (7) and an electric control device, wherein the position, corresponding tothe crushing cavity, of the feeding base is fixedly arranged on the machine body; the feeding bin, the material conveying device and the feeding shield are all fixedly mounted on the feeding base; the feeding shield is hermetically arranged outside the feeding bin, the material conveying device and the crushing cavity; the material conveying device comprises a speed-adjustable driving mechanism,a conveying mechanism, a sweeper (31) and a material sensor (32); and the electric control device comprises a PLC controller, a material conveying loop and a material crushing loop. The sample preparation crusher capable of automatically feeding is capable of avoiding the problem of locking of a crushing moving part, and realizing stable and continuous sample crushing, and is particularly suitablefor solid material sample preparation crushing operation in industrial analysis.

Description

technical field [0001] The invention relates to a sample preparation crusher, in particular to a sample preparation crusher capable of automatic feeding, and belongs to the technical field of sample preparation for industrial analysis materials. Background technique [0002] Industrial analysis is an analysis applied to industry, including chemical analysis and instrumental analysis. It is mainly used to test the specifications and purity of raw materials or finished products, and to determine whether they meet the requirements of relevant industries. Industrial analysis is analytical chemistry in industrial production. The application in it has the function of guiding and promoting production. It is known as the "eye" of industrial production and plays the role of "gatekeeper" in industrial production. [0003] Especially for the analysis of the coal industry, when coal is traded, it is necessary to detect and analyze the relevant indicators of the coal quality to determine...
