The invention discloses a simplified concentrated-seed-discharging-type precise hole-direct-seeding
machine for rice. The
machine comprises a rice transplanter power device, a hanging device, a rack,a
direct current driving motor, a
distributor, a seed discharging device, a seed box, seed guiding pipes, a
pesticide tank, a
pesticide spraying pump, a
pesticide liquid
pipe, a spray rod, furrow openers,
copying floating plate adjustment devices,
copying floating plate connection frames and a
copying floating plate; the seed discharging device is installed above the rack, the rack is installed onthe hanging device behind the rice transplanter power device, and the seed guiding pipes are installed between
distributor ports under the seed discharging device and seed throwing pipes of the copying floating plate openers; the copying floating plate openers are installed below the rack through the copying floating adjustment devices, the pesticide tank is pressurized by the pesticide sprayingpump and connected with the sealed weeding spray rod by adopting the pesticide liquid
pipe, and the sealed weeding operation is completed. The simplified concentrated-seed-discharging-type precise hole-direct-seeding
machine for the rice integrates the advantages of concentrated seed discharging, sealed weeding, device and tool simplification and the like, one seed discharging device can conduct precise hole-seed-discharging on six rice rows, and after seed discharging, the synchronous sealed weeding operation is conducted; the simplified concentrated-seed-discharging-type precise hole-direct-seeding machine for the rice effectively improves the work efficiency and the seed discharging precision, achieves device and tool structure simplification, and meets the
sowing operation requirementsof different regions.
