Abstract

The invention relates to a device, in particular a cross scraper type sampler for a coal transporting belt. The cross scraper type sampler comprises an electric motor, a rotary main body connected with the electric motor, a first sampling head driven by the rotary main body, a sampling chute corresponding to the first sampling head, and a support bracket for fixing equipment. The cross scraper type sampler is structurally characterized by comprising a second sampling head, a sampling chute corresponding to the second sampling head, and a shaft coupler for connecting the second sampling head with the rotary main body, wherein rotating shafts of the first sampling head and the second sampling head are respectively fixedly connected with a rotating shaft of the rotary main body. On the basis of the primary equipment, a second set of sampling system is added to redundantly and automatically intercept representative coal samples with zero error.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a sample collection and preparation device suitable for coal combustion analysis of a belt coal conveyor in a thermal power plant. Background technique [0002] Coal metering and automatic mechanical sampling are the prerequisites for thermal power plants to achieve positive balance calculation of coal consumption. "The thermal power plant calculates coal consumption for power generation according to the positive balance of the amount of coal fed into the furnace" points out that the mechanical automatic sampling device is currently the only one that can solve the problem of worker labor. The plan to increase the strength and reduce human factors is a means to collect representative samples, and it is also a necessary prerequisite for thermal power plants to reduce costs and increase power generation. [0003] Coal is one of the most difficult materials to sample because of its composition,...
