Abstract

The invention discloses an adjustable single-line small-particle crop precise hill planter. A drum shaft is arranged just below the middle of the left arm and the right arm of the rack of the hill planter; the left side of the drum shaft is provided with a drum, and the right side of the drum shaft is provided with a seed-metering device; the circumstance wall of the drum is provided with holes at intervals; the outer wall side of the circumstance of the drum is provided with a cave-digging and seed-sowing device by the hole; the inner wall side of the circumstance of the drum is provided with a seed clapboard by the hole; a seed conveying port is arranged below one side wall of the drum; a seed box is fixedly connected above the seed-metering device; a seeding rate adjusting plate is fixedly connected between the seed-metering device and the seed box; the outlet of the seed-metering device is fixedly connected with the upper end of a seed conveying slot; and the lower end of the seed conveying slot extends into the drum through the seed conveying port. In the invention, the seed-metering device is creatively applied to the hill planter, so that small-particle crops, especially small-particle crops with expensive seeds are precisely sown, thus greatly saving production input; and in addition, the invention can seed in untrimmed flat ground, or ridge tops and furrows of ridged land, especially hardened fields which secondarily utilize mulching films.

Description

Adjustable single file granule crop precise hole sowing machine

Technical field

The present invention relates to a kind of bunch planting farm machinery, especially at granule and the expensive a kind of adjustable single file granule crop precise hole sowing machine of seed kind.

Background technology

Chinese medicine lamiophlomis rotata seed, flax, Mi Gu etc. all are granule crops, and for a long time, because farming is extensive, the granule crop does not have new breakthrough on planting technology, yields poorly and unstable, and the waste of seed kind is serious.In recent years, along with the large tracts of land extensive use of plastic mulching cultivation technology, plastic mulching bunch planting culture technique is succeedd through experimental study, obtains demonstration and promotes, and has obtained significant effect of increasing production.But existing bunch planting facility mostly based on the crop of sowing larger particles, occur the bunch planting facility of granule crop and the granule crop hill-drop planter of the accurate control amount of sowing especially.

Summary of the invention

The invention provides a kind of special a kind of adjustable single file granule crop precise hole sowing machine at granule crop, the precision drilling of especially expensive granule crop energy.

For realizing above-mentioned technical purpose, adopt following technical scheme: a kind of adjustable single file granule crop precise hole sowing machine, comprise frame, cylinder, land wheel and handrail, the described frame right side, left arm are provided with drum shaft under the middle part; Cylinder is installed in the left side of this drum shaft, and seeding unit is installed on the right side; Spaced apart porose on the described roll circumference wall; This hole is equipped with out bunch planting seed device at the outer wall side of roll circumference, and this hole is equipped with the seed dividing plate in the inwall side of roll circumference; The below of one sidewall of described cylinder has defeated kind mouthful; The affixed seeds box in described seeding unit top, the affixed amount of broadcasting adjustable plate between this seeding unit and the seeds box; The outlet of described seeding unit and the defeated groove upper end of planting are affixed, stretch in the described cylinder by described defeated kind mouth and be somebody's turn to do the lower end of failing kind of groove;

The seed wheel of broadcasting in the described seeding unit is fixed on the described drum shaft, and the obstruction wheel in the described seeding unit is sleeved on the described drum shaft; This is broadcast the seed wheel and blocks the end of wheel in described seeding unit and contacts, and its other end all stretches out outside the described seeding unit; The described seed wheel broadcast thinks that by an inner surface and its outline adaptive cover stretches out outside the seeding unit, and the projection on the described obstruction wheel outer surface snaps in the draw-in groove on the seeding wall, and should block wheel can be along described draw-in groove slip.

The present invention is applied to seeding unit in the hill-drop planter with innovating, make the granule crop, especially the granule crop of seed kind costliness has been realized the purpose of precision drilling, saved greatly to produce and dropped into, and the present invention is adapted at various soils upper seeding wheel, as untrimmed level land, or in the ridge on the ridging ground top, furrow, especially can sow on the ground that hardens of second use mulch film in; Solved the difficult problem of granule crop sowing in the mulch film ground, and realized the semi-mechanization sowing, improved 26 times than by artificial seeding's efficient.

The present invention is simple in structure, volume is little, in light weight, cost is low, easy for operation.
