Wherein, two fixed stations of described fixed part are arranged to symmetrical structure.
Wherein, described pair of fixed station inside is provided with the circular arc draw-in groove.
Wherein, two edges of described suction nozzle are arranged to symmetrical structure.
Wherein, the structure of described pair of edge is set to radiused edges.
Wherein, the exhaust head of described fixed part is provided with certain taper, is convenient to fixed part and suction nozzle closely cooperates.
Wherein, the diameter of bore of the sucking needle of described suction nozzle is at 0.1-1.2mm, to adapt to absorption different-grain diameter seeds in size.
(3) beneficial effect
With inhaling kind of a head, compared with prior art, the technique effect that can obtain is by above-mentioned a kind of cave tray seeder: can realize that negative pressure inhales kind the sowing technology of malleation air blowing seeding; By changing the suction nozzle in different apertures, the crop seed of adsorbable different-grain diameter size; After the cave tray seeder sets suction kind head of the present utility model, can after finish, suction kind of a malleation seeding operation in inhaling kind of a return stroke, connect high barotropic gas suction nozzle is dredged raising sowing efficient.
