Assembly line type operation method for automatic precision seeding

The invention discloses an automatic precision sowing assembly line type operation method suitable for sowing and seedling raising of vegetable seedling raising trays, and the whole operation process comprises a seed distribution process, a seed filling process, a seed collecting process, a resetting process before seed falling, a seed discharging and falling process and a resetting process after seed falling. The control part controls the conveying part arranged on the machine frame to convey seedling raising plates to the position below the sowing part, the sowing part achieves precise sowing through the reciprocating motion mechanism and the rotating mechanism, the seedling raising plates conveyed to the position below the sowing part receive seeds discharged by the sowing part, and therefore sowing is completed. According to the automatic precision seeding machine, automatic precision seeding of the seedling trays with different sizes can be realized, the single seed filling rate is increased, the seeding
