Abstract
The invention discloses a convex suction-hole aspiration planter plate, which aims at providing a convex suction-hole aspiration planter plate with stable and reliable planting performance. The convex suction-hole aspiration planter plate comprises the body of the planter plate and a mounting hole arranged on the body of the planter plate. The body of the planter plate is designed into a disk shape, the surface of which is smooth and plat; and convex suction-holes are uniformly arranged along the circle direction on the body of the planter plate. The convex suction-holes are designed to be outwards convex to one side of the surface of the planter plate; ventilating suction-holes are processed in the center of the convex part; the number of the convex suction-holes is 25 to 40. The convex suction-hole aspiration planter plate is suitable for the aspiration fine planting operations of farming crops in beans, corns, sugar beets, grain sorghums, and the like.
Description
Technical field
The present invention relates to the seeding parts in a kind of seeding machinery, especially relate to a kind of convex suction hole type air-suction planter plate that is applied on the air-sucking type grain precision seeder seeding unit.
Background technology
The air-sucking type grain precision seeder is used for the precise sowing of intertillage crop such as corn, soybean, beet, Chinese sorghum etc., and air-suction seeding unit is its critical component that reaches precise sowing.Advantage is that precise sowing can be saved a large amount of seeds, can adapt to the seeding operation of higher speed, and the seed damage ratio is little, and it is neat, strong, even to reach seedling, helps increasing production stable yields.
Air-suction seeding unit has two kinds of vertical disc type and seeding drum-types on version.But the seeding drum-type is a large amount of production uses because performance can not be stablized.Vertical disc type aspiration seeding unit structure is compact, and seed-metering performance and versatility are better, can precise spot-sowing, the bunch planting various crop, be widely used on the precision planter at present.Vertical disc type aspiration seeding unit by seeding body, induction chamber housing, seed plate, stir kind of wheel and seed scraping device etc. and form.Seed plate is generally made with 1.5～3mm corrosion resistant plate, and any surface finish is smooth, and the hole is inhaled in processing on the seed plate.Though this technical scheme has solved technical problems such as simplified structure, high speed operation, seed-metering performance and versatility, but part still has some deficits: because the seed plate any surface finish is smooth, when the seed plate high speed rotating, inhale on the hole and be drawn onto many seeds sometimes simultaneously, phenomenon such as therefore often replay, spacing in the rows is irregular; Again owing to be drawn onto under many kind subcases, inhaling the hole can not be blocked fully by seed, cause and inhale hole gas leakage, suction deficiency, when inhaling the hole when producing induction chamber and charging seed, seed breaks away to be inhaled in the process of hole, rub with seed plate surface, the accuracy of charging seed is descended, phenomenon such as the therefore same spacing in the rows of generation easily is irregular.As seen, exist the reliable and stable inadequately problem of seed-metering performance.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of seed-metering performance reliable and stable convex suction hole type air-suction planter plate.
For achieving the above object, the present invention adopts following technical proposals: convex suction hole type air-suction planter plate of the present invention comprises the seed plate body, is arranged on the installing hole on the seed plate body.Described seed plate body is designed to the smooth circular plate shape of smooth surface, on this seed plate body, the along the circumferential direction uniform protruding suction hole that is provided with, this protruding suction hole is designed to this seed plate body surface one side direction outer lug relatively, be positioned at the penetrating suction of this projection central authorities processing hole, the quantity in this protruding suction hole is 25～40.
As the improvement of convex suction hole type air-suction planter plate of the present invention,, and be positioned on the circular cone of described seed plate body to outer lug one side in this protruding suction hole, kind of a tooth is stirred in along the circumferential direction uniform setting, and this quantity of stirring kind of tooth is 10～18.
As the further improvement of convex suction hole type air-suction planter plate of the present invention, the quantity in described protruding suction hole is 30.
As the further improvement of convex suction hole type air-suction planter plate of the present invention, described quantity of stirring kind of tooth is 15.
As convex suction hole type air-suction planter plate of the present invention, kind of the tooth that stirs of described seed plate body and uniform setting along the circumferential direction adopts the aluminium alloy integrally casting.
The invention has the beneficial effects as follows: because on this seed plate body, the along the circumferential direction uniform protruding suction hole that is provided with, this protruding suction hole are designed to this seed plate body surface one side direction outer lug relatively.Therefore helping protruding suction hole can fully contact seed, guarantees that each protruding suction hole can only be drawn onto a seed, and the induction chamber sealing is air tight, suction is strong, and when protruding suction hole was produced induction chamber and charged seed, seed broke away from the process of protruding suction hole, do not rub with the seed plate surface, improved the accuracy of charging seed.Thereby obtain the reliable and stable effect of seed-metering performance.
