Abstract

The invention discloses a coal sampling machine with position and posture maintaining of a sampling head, which belongs to the field of coal sampling. The invention includes a sampling base and a hydraulic articulating arm, and a sampling head posture maintaining mechanism is arranged on the side of the hydraulic articulating arm. In actual use, the position of the sampling head is precisely adjusted through the simultaneous action of the hydraulic cylinder in the hydraulic joint arm and the position and posture maintaining mechanism of the sampling head. Compared with the prior art, the relative position of the sampling head relative to the sampling position can be maintained. Stable, which is conducive to accurate sampling of commercial coal, thereby improving the efficiency of sampling, so that the quality of commercial coal can be accurately judged according to the collected samples.

Description

technical field [0001] The invention relates to the field of coal sampling, in particular to a coal sampling machine with position and posture maintaining of a sampling head. Background technique [0002] In the coal trading process, the tens of thousands of tons of coal provided by the supplier should have the same surface quality as the internal quality. However, there are many sources of coal traded in the market, and the quality of coal in different batches and production areas varies greatly. In addition, some coal sales units dope coal into fake coal and pass it off as good ones out of commercial interests. Therefore, commodity coal sampling and testing is an indispensable and important link in coal trading. In order to judge the quality of coal fairly, the coal should be sampled according to the prescribed, scientific and reasonable method. [0003] In the prior art, when coal is sampled, it is necessary for a worker to climb up a coal pile or a carriage to randomly...
