AI Technical Summary

Technical Problem

The existing coal hardness detection technology has low accuracy and is difficult to achieve accurate detection of coal hardness.

Method used

Design a mineral hardness detection device, including a sample preparation assembly, a detection assembly and a control and calculation assembly. The sample preparation assembly drills the mineral sample into a preset shape and size test sample through a hollow drill. The test assembly extrudes the test sample until it breaks and detects its ultimate pressure. The control and calculation assembly calculates the uniaxial compressive strength and converts it into the mineral solidity coefficient.

Benefits of technology

Accurate automatic detection of mineral hardness is achieved, detection errors are reduced, detection accuracy and efficiency are improved.

Abstract

The invention discloses a mineral hardness detection device and a detection method thereof, a coal mining machine and a mineral classification method, which can make a mineral sample into a detection sample, and obtain a mineral firmness coefficient by detecting the ultimate pressure of the detection sample, thereby realizing accurate and automatic detection of mineral hardness. The mineral hardness detection device comprises a moving trolley, a sample preparation assembly, a detection assembly and a control and calculation assembly. The sample preparation assembly comprises a hollow drill (19), a drilling machine driver (16), a lifting mechanism and a fixing mechanism. The detection assembly is used for extruding the detection sample to detect the pressure on the detection sample and transmitting the pressure on the detection sample to the control and calculation assembly. And the control and calculation assembly is electrically connected with the detection assembly and is used for obtaining the ultimate pressure of the detection sample according to the pressure of the detection sample, calculating the uniaxial compressive strength of the detection sample and converting the uniaxial compressive strength into a mineral firmness coefficient for display.
