Abstract
The utility model provides a precise seeding unit of a seeder, comprising a driving shaft, a seed plate, a seed dropping plate, a seed cylinder, a seed scrapping machine and a seed dropping machine, wherein a bearing of the driving shaft is installed on the seed dropping plate; a round table type seed plate is fixed at the upper end of the driving shaft; the bottom of the seed plate is contacted with the seed dropping plate in a propping manner; the seed plate, the seed dropping plate and the seed cylinder share the same circle center; the periphery of the seed plate, close to the outer edge, is uniformly distributed with seed holes; the seed dropping machine is positioned above the seed holes which are arranged below the seed dropping machine; and the side surface of the seed scrapping machine, facing the rotating direction of the seed plate, forms an acute angle with the vertical surface. The precise seeding unit is characterized in that the seed holes are tangent with the circumference of the seed plate; the diameter of each seed hole is 13-18mm, and the side surface of each seed hole, facing the rotating direction of the seed plate, is provided with a seed guiding groove. When the seed holes full of seeds rotate to the seed scrapping machine, the side surface of the seed scrapping machine, facing the rotating direction of the seed plate, scraps the spare seeds, so that only one seed is left in the seed hole; the seed dropping machine drops the seed from the seed dropping hole, thus not only reducing the damage on the seed, but also guaranteeing the single-hole single-seed sowing.
Description
Technical field
The utility model relates to a kind of sower precision seeder, belongs to agricultural machinery technological field.
Background technology
Seeding unit is as the core component of precision planter, and national standard all has strict requirement to the simple grain rate and the seed breakage of seeding process; If feed outlet can not fill kind or fill and plant many, then can cause the appearance of broadcast leakage or replay problem, can not satisfy the seeding accuracy requirement; If the seed breakage then can not guarantee seed germination rate.
For the smooth filling that guarantees seed and avoid damage to seed; traditional horizontal circle disc type seeding unit is big to the seed damage in the course of the work; and because feed outlet is the cylindricality feed outlet; can not guarantee that the feed outlet simple grain fills the needs of planting; the novel filling of not only being convenient to feed outlet of this use; and help removing unnecessary seed; and reduced of the damage of seeding process to seed; and because seed is through the pill processing; guaranteed seed germination rate; realized the precise sowing of single hole simple grain truly; this is novel applied widely simultaneously; be applicable to multiple big particle diameter seed, changed the situation that traditional precision planter can only carry out single sowing.
The utility model content
The purpose of the utility model patent provides a kind of sower precision seeder that can overcome above-mentioned defective, the seed damage of minimizing sowing process and guarantee the big particle diameter seed after simple grain fills kind and is applicable to multiple pillization.Its technical scheme is:
Comprise driving shaft, seed plate, the plate of charging seed, be fixed on the seed can on the plate of charging seed, be fixed on seed scraping device and the seeds depositing apparatus that is suspended on the seed scraping device on the seed can inwall, wherein driving shaft bearing is installed on the plate of charging seed, round table-like seed plate is fixed on the upper end of driving shaft, conflict with the plate of charging seed in the bottom, seed plate, charge seed plate and seed can concentric, seed plate is near being evenly equipped with feed outlet around the outer rim, seeds depositing apparatus is positioned at the seed plate top, and be positioned on the circumference with diameter with feed outlet, charge seed and also establish charge seed hole and a feed outlet on the plate and be positioned on the circumference with diameter, seed scraping device is met to the side of seed plate rotation direction and vertical plane and is acutangulated, it is characterized in that: the circumference of feed outlet and seed plate is tangent, diameter 13～18mm, and each feed outlet is met to the side of seed plate rotation direction and is had seed guiding groove.
Described sower precision seeder, seed plate is connected with the driving axle key.
Its operation principle is: on seed scraping device, the bottom is undertaken on the seed plate seeds depositing apparatus through spring suspended.The drive shaft seed plate rotates, and the seed in the seed can is full of feed outlet under gravity and action of centrifugal force.When the feed outlet that is full of seed forwards seed scraping device to, only stay a seed in the feed outlet, unnecessary seed is wiped off by the side that seed scraping device contacts with seed plate, and seeds depositing apparatus probes in the feed outlet, and seed is launched from the hole of charging seed, and realizes the single hole monoseeding.
The utility model compared with prior art has following advantage:
1, seed plate is truncated cone, guaranteed around the seed energy automatic stream seed plate, because feed outlet is evenly distributed on the seed plate tangent with the circumference of seed plate, the aperture of feed outlet is slightly larger than the seed particle diameter, and feed outlet is met to the side of seed plate rotation direction and is had seed guiding groove, it is kind convenient and reliable to make that simple grain fills, and has guaranteed the required precision of sower;
2, seed scraping device and truncated cone-shaped seed plate are pressed close to, and meet to the side of seed plate rotation direction and be acute angle with vertical plane through this base, side, not only can scrape off the unnecessary seed of feed outlet, and reduce the seed damage has been prevented the appearance of damaged seed;
3, strengthened the feed outlet diameter, the big particle diameter seed applicable to after the multiple pillization has improved the use value that changes precision planter.
