description The invention relates to a timed and quantitative sampling mechanism, and belongs to the field of sampling technologies in the material conveying process. The sampling device comprises a sampling pipe used for being connected with the lower end of a conveyor, the sampling pipe is provided with a first valve and a second valve at intervals in the length direction of the sampling pipe, and the sampling pipe is located between the first valve and the second valve to form a storage section. Materials fall into the material storage section formed between the first valve and the second valve under the action of self weight in the conveying process, and when sampling is needed, the materials in the material storage section can be taken out to be detected only by closing the first valve and opening the second valve, so that the effects of sampling quantitatively at regular time and being beneficial to improving the sampling detection precision are achieved. 本申请涉及一种定时定量取样机构，属于物料输送过程中取样技术的领域；其包括用于与输送机下端连接的取样管，所述取样管沿自身长
