A Coal Mechanized Sampling Equipment Easy to Adjust

Abstract

The invention discloses a coal mechanized sampling equipment that is easy to adjust, comprising a mechanical arm, a first motor is fixedly installed on the bottom side of the mechanical arm, and a rotating shaft is fixedly installed on the output shaft of the first motor through a first coupling. The bottom end of the rotating shaft is fixedly equipped with a telescopic rod, and a sleeve rod is movably sleeved on the telescopic rod. The top of the sleeve rod is provided with a mounting groove along the vertical direction. The end is provided with a first rotating groove along the vertical direction, and a rotating rod is installed in rotation in the first rotating groove, and a second motor is fixedly installed on the inner wall of the bottom side of the mounting groove. The invention can conveniently adjust the length of coal mechanized sampling equipment, and at the same time, the sampling head is easy to dismantle and install, so that the sampling head can be better maintained, thus prolonging the service life of the sampling equipment, and the sampling knife can be extended to Appropriate width.

Description

technical field [0001] The invention relates to the technical field of coal, in particular to a coal mechanized sampling device which is easy to adjust. 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] The publication number is CN206930478U, which discloses a high-efficiency coal sampler in the field of coal sampling equipment technology, i...

Problems solved by technology

[0003] The publication number is CN206930478U, which discloses a high-efficiency coal sampler in the field of coal sampling equipment technology, including a mounting seat, the top of which is movably connected with a boom, and a large Arm oil cylinder, the top of the big arm is connected with the small arm arranged horizontally, the inner cavity of the sampling device is vertically provided with a rotating shaft, and the outer wall of the rotating shaft is uniformly provided with a spiral feeding plate, and the rotating shaft runs through the top of the sampling device One end is equipped with a belt pulley, and the top right side of the sampling device is also equipped with a discharge port. However, the coal mechanized sampling equipment in this equipment is mostly fixed, and the length cannot be adjusted, resulting in insufficient sampling depth, and the sampling head is not easy to disassemble. , it is easy to cause sample contamination, and at the same time, the head cannot be flexibly adjusted according to the required area, resulting in poor sample quality and low sampling quality
