The work process of the present invention is as follows:
During work, negative-pressure air-flow is entered by air inlet pipe 5 and is made up of rear air chamber dish 2, discharge plate 6 and front air chamber dish 7
Confined air air chamber, and form draught head with outside air chamber in air chamber.Seed is entered seed-storage box 11 by kind of case 10 and passes through
Seed inlet 105 enters inside feed mechanism for seed.Under the effect of seed inlet catch 104, seed in seed inlet catch 104 upper end, enter plant
Forming the population contacted with the discharge plate sidewall 603 of discharge plate 6 at mouth 105, seed is under the effect of self gravitation and draught head
Absorption is on type hole 605.One or more seeds may be adsorbed in each type hole 605, and discharge plate 6 rotates under the drive of sprocket wheel 3,
Along with the rotation of discharge plate 6, adsorbed seed is taken at Seed-cleaning tool 9 by discharge plate 6, and seed, under the effect of Seed-cleaning tool 9, is located
Seed in type hole 605 vantage point is adsorbed tighter by draught head, and the seed being in unfavorable position departs from the effect of draught head,
Dropping back into population under gravity, each type hole 605 leaves a seed.Along with being rotated further of discharge plate 6, seed is brought to
Unload at kind of cutter 13, unload each gear teeth of kind of cutter 13, a corresponding type hole 605, unload at kind of cutter 13 when seed turns over, unload kind of cutter 13
Type hole 605 is covered by the gear teeth, and seed ejects type hole 605, and now seed loses absorption affinity, departs from seeding under gravity
Dish 6, leaves feed mechanism for seed by sowing port 107, completes seeding process.
After the end of job, in planting case 10 and seed-storage box 11, remaining seed empties by the way of opening and unloading kind of plate 114.
