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...

AI Technical Summary

Problems solved by technology

[0005] The number of samples required for industrial analysis is usually small. In the process of sample preparation and crushing, adding the material samples to be crushed into the crushing cavity is usually done manually, that is, the operator gradually sends the coal sample into the inlet of the sample preparation crusher according to visual inspection or experience. In the material hopper, not only can it not guarantee stable and continuous feeding, but also the labor intensity of the operators is high, the requirements for the skills of the operators are high, and the work efficiency is low; at the same time, because the sample crusher generally adopts relatively small power and small size Crusher, so the feeding speed needs to be controlled at the feeding port. If the feeding amount is too much and too fast, the crushing moving parts of the sample crusher will be stuck, and the outer cover needs to be opened to clean the crushing cavity, which is time-consuming and laborious. If the jam is severe and the power is not cut off for a long time, the drive motor will be burned; for the crushing and shrinking integrated sample crusher, the manual feeding method makes it difficult to guarantee the uniformity of shrinking and dividing
