The utility model discloses a novel sampling device for seed inspection, which relates to the technical field of seed sampling and comprises triangular plates, and when the four triangular plates are connected with one another, the front end of a sampling tube can be blocked to prevent impurities from entering the sampling tube; a conical structure formed by the four triangular plates is convenient for the sampling pipe to be inserted into a seed pile for sampling; the sliding block can push the four push rods to move simultaneously, and it is guaranteed that the four triangular plates can rotate simultaneously. The front end of the push rod is of an arc-shaped structure, friction between the push rod and the triangular plate can be reduced, and normal movement of the push rod is guaranteed; scale marks on the outer wall of the sampling tube facilitate control of the depth of the sampling tube inserted into the seed pile; the sampling tube is in threaded connection with the test tube to facilitate mounting an
