Precision seed picking device for precision seeding machine

The invention relates to a precision seed picking device for a precision seeding machine, belonging to the technical field of agricultural machines. The precision seed picking device comprises a transmission shaft pipe, a seed storage box, seed picking discs and a seed receiving box, wherein the seed picking discs are arranged on the transmission shaft pipe at intervals by virtue of communication holes; the seed storage box is arranged below the transmission shaft pipe, one end of each seed picking disc extends into the seed storage box, the rear end of the seed storage box is provided with the seed receiving box, the seed receiving box is provided with a seed picking plate, a seed scraping plate is arranged above the seed storage box by virtue of a mounting rod, and the seed picking plate and the seed scraping plate are respectively in contact connection with each seed picking disc. The precision seed picking device disclosed by the invention is simple in structure; the problems that an existing seeding machine can only be used for seeding crop seeds with relatively large particle sizes, and aiming at crop seeds with relatively small particle sizes, uneasy seed metering control, very serious heavy strain phenomena after seeding, and excessive crop seed consumption are caused due to structure reasons of the seeding machine can be solved; and the precision seed picking device is particularly suitable for being arranged and used by the seeding machine.
