Abstract
Three-cylinder sampler three-cylinder sticking sampler, and relates to a grain inspection sampling instrument, for solving the problems that in the prior art the sampling speed is greatly affected as the total mass of the impurities of a sample is increased and the loading and conveying process is relatively complex due to the fact that a great amount of impurities at a sticking hole are likely to be sucked into the sample. The three-cylinder sticking sampler combines the advantages of manual sampling sticking and vacuum suction sampling sticking, and comprises an inner cylinder, a middle cylinder and an outer cylinder from inside to outside in sequence, wherein the middle cylinder and the outer cylinder are integrally connected and move simultaneously; a plurality of first feeding grooves are formed in the outer wall of the middle cylinder; and a plurality of second feeding grooves which are the same as the length, the space and the number of the first feeding grooves are further formed in the outer wall of the outer cylinder. The three-cylinder sticking sampler realizes the manual sticking sampling effect, is convenient to operate and uniform in sampling, and moreover the rapid conveying of the sample is realized, so that the reality and the timeliness in sampling inspection are ensured.
