Direct seeding rice quantitative precision seeding equipment

The utility model relates to quantitative precision seeding equipment for direct seeding rice. a large batch of rice seeds are equally divided twice; firstly, seeds in a stirring cylinder are equallydivided into small batches by utilizing a fixed disc and an index plate; the quantity of the seeds in each indexing groove is almost the same; the quantity error can be reduced by equally dividing insmall batches; then, the two groups of mutually matched indexing plates are used; a small batch of seeds stored in a cylinder on the overturning disc enter a placement groove in the overturning disc through a blanking hopper; secondary aliquot, at the moment, secondary equal division is performed; the error standard of the quantity of the seeds falling into the placement groove is reduced; the precision of the number of the seeds is improved, the two groups of overturning discs are used for alternately seeding, the seeding continuity is ensured, miss-seeding is avoided, the seeds in rice seedholes are concentrated, and
