Description
Technical field
The present invention relates to millet precision seeder technical field, specially a kind of millet precision seeder.
Background technique
Millet, Gu claim grain, fine strain of millet, are drought-enduring plants, water-saving agriculture, are once northern staple food grain, imperial-cereals, soldier's pay and provisions, currency, and in
Ward produces, and is the world grain market, unique competitive grain variety, also just because of specialty, without ready-made mechanization mould
Formula and equipment, comparative effectiveness is low, and sown area sharply declines, thus realizes its mechanized farming, since sowing, restores millet
Significant, millet precision seeder is produced, function is to solve the conventional tillage technological transformation of Chinese specialty millet, that is, realizes " old
The Chinese is not planted with a drill barrow, and rear raw do not draw is ramed the loose soil with a stone-roller after sowing, and son's wife saves thinning, saves work section kind 70%, 30% " target of increasing both production and income, millet precision seeder, core
Technology is that the basic breakthrough of feed mechanism for seed, i.e. seed percentage of damage drop to 0, and cave plant spacing pass rate keeps 98% or more, seed number per 4
± 1 is adjustable, and percentage of damage is critically important, otherwise is rice mill, and seed waste is serious, is unfavorable for the popularization of excellent precious seed, cave
Plant spacing pass rate is also important, determines that mu stays seedling cave strain number, to determine per mu yield, seed number per is also important, and one is more as far as possible,
To guarantee collective's Emergence of seed, simple grain is not all right, and the native ability in millet top is weak, and it is dead to be easy circle, and causes the disconnected ridge that is short of seedling,
Two, to lack as far as possible, to guarantee that the later period lacks thinning or not thinning, millet precision seeder, the relevant technologies are, sow cell cube, have
Profiling, to guarantee that seed level is consistent, to reach, emergence is consistent, and millet precision seeder, the relevant technologies are, suppresses device wheel group, the
One will have certain suppression compactness, reach 1 kilogram/1 square centimeter or more, and quite adult foot is stepped on, and just can guarantee seed in this way
With being intimately associated for soil, promote its water suction-germination-emergence, second will have certain ridge eye bulge-structure, i.e. 120 degree of triangles
Slope surface, after raining, water is flowed toward both sides, to prevent soil hardening, influences to emerge.
Existing millet precision seeder carry out using when, can be carried out in the form of being sowed when loosening the soil, but plant
Son is easy to block feed opening when carrying out blanking, blocks the progress for continuing blanking, it has not been convenient to be operated, Er Qiekai
