Ultrahigh pressure water jet coal sample cutting preparation machine

Abstract

The invention relates to an ultrahigh pressure water jet coal sample cutting preparation machine. The preparation machine comprises a cubic worktable, wherein the upper part of the worktable is provided with a gridded tray; one side of the worktable is provided with a vertical supporting arm; the upper end of the supporting arm is provided with a dovetail groove; a dovetail-shaped Z-direction guide rail arm is arranged in the dovetail groove in a matching mode; the upper part of the Z-direction guide rail arm is connected with a Y-direction lifting arm; one side of the Y-direction lifting arm is transversely bent to form a transverse arm; a disc-shaped fixing arm is arranged on the transverse arm; the lower part of the disc-shaped fixing arm is fixedly connected with an X-direction guide rail arm; and a cutting machine is assembled on the X-direction guide rail arm in a sliding mode. According to the preparation machine, when a coal sample is cut, the phenomenon that the coal sample is shaken, collided and crushed is avoided, the problems that the coal body is heated and combusted, the efficiency is low and the environment is polluted by the pulverized coal in the coal core drilling process can be well solved, the operation is stable and high-efficiency, the samples are effectively saved, the quality of the sampled sample is improved, and great benefits are brought to scientific research.

Description

technical field [0001] The invention relates to a coal sample preparation machine for cutting coal samples of various coal ranks, in particular to an ultra-high pressure water jet cutting coal sample preparation machine capable of cutting fragile coal samples with high efficiency. Background technique [0002] At present, the preparation of cylindrical coal samples is mainly completed by ordinary drilling rigs. Due to the special physical and mechanical properties of coal, the problems of coal fragmentation, excessive heat generation, and excessive coal powder often occur in the traditional sample preparation process. . These problems directly lead to the low quality of drilled samples, which brings great inconvenience to scientific research work. Ultra-high pressure water jet technology has been widely used in the cutting and processing of stone and metal fields. This technology is introduced into the coal sample preparation process. By redesigning the operating platform, ...
