The invention relates to a precision seed distributing machine with double gate segments, and belongs to the technical field of seed sowing equipment. The precision seed distributing machine comprisesa mounting frame, a plurality of seed tanks, the upper gate segment, the lower gate segment, two main driving barrels and two auxiliary driving barrels. The seed tanks are mounted on the mounting frame at intervals; seed guide pipes are mounted on the mounting frame and are positioned below the seed tanks; a seed distributing rotary shaft is mounted on the mounting frame via bearing blocks and ispositioned between the seed guide pipes and the seed tanks; driving chain wheels are fixedly arranged at two ends of the seed distributing rotary shaft; the two auxiliary driving barrels and the twomain driving barrels are symmetrically fixedly arranged on the seed distributing rotary shaft; the upper gate segment and the lower gate segment are slidably arranged at the lower ends of the variousseed tanks in the up-down directions; guide wheels are arranged at two ends of the upper gate segment and two ends of the lower gate segment. The precision seed distributing machine with the double gate segments has the advantages that the precision seed distributing machine is ingenious in design, the problems of difficulty in changing types and inaccurate seed fetching of existing precision seeddistributing machines can be solved by the aid of the precision seed distributing machine, and the precision seed sowing requirements of people can be met by the precision seed distributing machine.
