Abstract
Gravity can be utilized to fill the vertical seeding disk of planting and to belong to agricultural machinery; Seed plate entirety is in peviform, the seed plate side wall inner surfaces entirety of described peviform is in cone shape, on the seed plate sidewall of peviform, kind of a nibs is filled in along the circumferential direction uniform setting, in the seed plate pelvic cavity of peviform, configure the basin shape seeds protecting plate matched with it, the part on the seed plate sidewall of peviform is filled kind of a nibs and is blocked covering by described basin shape seeds protecting plate sidewall; This structure to make use of between seed lateral pressure that extruding mutually produces and seed self gravitation and completes and fill kind of an operation, and seed-filling rate is improved, and has novel structure, reasonable, simple, cheap for manufacturing cost, planting quality is good, service-strong feature.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of vertical disc seeding device.
Background technology
Vertical seed plate in traditional vertical disc seeding device is all employing circular plate disk bodies, and the structural design of kind of nibs is filled in the uniform setting in circular plate disk body circumferential edges position place, because it has the plurality of advantages such as axial dimension is little, structure is simple, transmission is convenient, charge seed accurately, spacing in the rows variation size is little, seedling-damaging rate is low, in agricultural production, obtain more application.But, it is that kind of grain is filled in kind of nibs by the lateral pressure that the interphase interaction of single utilization seed produces that the vertical seed plate of this class formation fills kind of mode, and seed self gravitation cannot be utilized to have assisted fill kind of an operation, cause traditional vertical disc type seeder under high-speed rotation operating condition, fill kind of effect not satisfactory, seed-filling rate still needs to improve.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing, and design provides a kind of gravity that utilizes to fill the vertical seeding disk of planting, and reaches the object improving vertical disc seeding device seed-filling rate.
The object of the invention is achieved in that seed plate entirety is in peviform, the seed plate side wall inner surfaces entirety of described peviform is in cone shape, on the seed plate sidewall of peviform, kind of a nibs is filled in along the circumferential direction uniform setting, the basin shape seeds protecting plate matched with it is configured in the seed plate pelvic cavity of peviform, part on the seed plate sidewall of peviform is filled kind of a nibs and is blocked covering by described basin shape seeds protecting plate sidewall, so far forms a kind of gravity that utilizes and fills the vertical seeding disk of planting.
Both the lateral pressure that extruding mutually produces had been make use of between seed when the invention is filled kind, utilize again and played seed self gravitation, both combination makes vertical disc seeding device seed-filling rate and fill kind of a performance and be improved under operating condition at a high speed, has novel structure, reasonable, simple, cheap for manufacturing cost, planting quality is good, service-strong feature.
Accompanying drawing explanation
Fig. 1 can utilize gravity to fill the vertical seeding disk schematic diagram of planting;
Fig. 2 is the right view of Fig. 1;
In figure, piece number illustrates:
1, basin shape seeds protecting plate, 2, seed plate, 3, fill kind of a nibs
Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.A kind of gravity that utilizes fills the vertical seeding disk of planting, seed plate 2 entirety is in peviform, the seed plate 2 side wall inner surfaces entirety of described peviform is in cone shape, on seed plate 2 sidewall of peviform, kind of nibs 3 is filled in along the circumferential direction uniform setting, in seed plate 2 pelvic cavity of peviform, configure the basin shape seeds protecting plate 1 matched with it, the part on seed plate 2 sidewall of peviform is filled kind of nibs 3 and is blocked covering by described basin shape seeds protecting plate 1 sidewall.
During operation; fill in kind of region on the downside of vertical disc seeding device enclosure interior; under the lateral pressure that seed produces between seed and self gravitation acting in conjunction; what be filled into seed plate 2 rotationally fills in kind of nibs 3; continuing, you make the seed be filled with in kind of nibs 3 turn to seed plate 2 outside the sowing port place discharge seeding unit at position on the downside of housing under the common protection maintaining static geobasin shape seeds protecting plate 1 and housing, complete seeding operation.Circulate successively.
