Abstract
The invention provides an accurate seed sowing device with variable depths of mould holes, which comprises a shell body with upper and lower openings, an outer grooved wheel arranged inside the shell body, a brush wheel and a mould hole wheel, wherein the axial lines of the outer grooved wheel, the brush wheel and the mould hole wheel are in parallel. The outer grooved wheel, the brush wheel and the mould hole wheel are installed on three shafts of a seeder through linkages respectively. The rotation directions of the brush wheel and the mould hole wheel are opposite to that of the outer grooved wheel. The accurate seed sowing device is characterized in that the holes of the mould hole wheel are through holes. A loose pin sheathed with a spring is fit in each hole with clearance. A mould hole is formed by the hole of the mould hole wheel and the outer end of the loose pin. The outer grooved wheel is positioned above the mould hole wheel and the outlines of the outer grooved wheel and the mound hole have a distance of 20mm to 40mm. One side of the outer grooved wheel is closely jointed with the inner wall of the shell body while the other side thereof and the inner wall of the shell body form a seed channel. One side of the mould hole wheel, which is close to the seed channel, is closely jointed with the inner wall of the shell body. The brush wheel is positioned away from the seed channel and obliquely on the mould hole wheel, and is in contact with the mould hole wheel. An additional cam and the mould hole wheel are fixed on the shell body coaxially and the additional cam is positioned at the center of the mould hole wheel. The outline of the cam is in contact with the inner end of the loose pin. The seed sowing device has high single grain rate and little damage to seeds.
Description
Technical field
The invention provides a kind of type hole depth type variable precision seeder, belong to agricultural machinery technological field.
Background technology
Along with promoting the use of of the elite seed of costliness, more and more urgent to the requirement of accurate simple grain bunch planting seeding unit.Precise sowing not only can be saved breeding, and can reduce field thinning, final singling recruitment, can reduce the land fertility waste again, improve crop yield.Therefore, all widely-used in a lot of countries.
One of key technology that realizes precise sowing is that seeding unit can be realized simple grain bunch planting requirement.China just began one's study and promotes the precise sowing technology from the beginning of the seventies, but was not widely used so far, and its reason is a lot, but mainly is that seeding unit can not meet the demands.External precision seeder adopts pneumatic type more, its complex structure, price height, use inconvenient maintenance.Chinese scholars generally believes that hole roller formula seeding unit is simple in structure, price is low, use is easy to maintenance, is fit to broadcast large seed, is comparatively ideal seeding unit.But exist to seed damage ratio height, to shortcoming such as seed sizes is strict.For this reason, many scholars have carried out extensive studies and exploration, as add the filling wheel, and strength is filled kind of clear a kind, uses rubber brush kind wheel, compound type hole filling seed inside, adjustable type hole filling seed inside etc.But all be difficult to improve the simple grain rate of the planting seed of difformity and size in filling separation, clear overall process of planting quantitative and seeding.
Summary of the invention
The purpose of this invention is to provide a kind ofly can overcome above-mentioned defective, simple grain rate height, to the little type hole depth type variable precision seeder of seed damage.Its technology contents is:
A kind of type hole depth type variable precision seeder, the housing and the outer groove-wheel that is positioned at housing that comprise upper and lower opening, brush wheel, hole roller, outer groove-wheel wherein, the axis of brush wheel and hole roller is parallel, be installed on three axles of sower through key respectively, brush wheel, turning to of hole roller is opposite with outer groove-wheel, it is characterized in that: the hole of hole roller is a through hole, the pin of living of equal matched in clearance one pocketed springs in each hole, the hole of hole roller and the pin formation type hole, outer end of living, outer groove-wheel is positioned at the top of hole roller, both outlines are at a distance of 20～40mm, one side of outer groove-wheel and inner walls are fitted, opposite side and inner walls constitute kind of a subchannel, hole roller is near side of planting subchannel and inner walls applying, and brush wheel is positioned at the oblique upper of hole roller away from the seed passage, and contacts with hole roller, set up the center that a cam and hole roller coaxial line are fixed on the housing and are positioned at hole roller, the outline of cam and the interior end in contact of living and selling.
Described type hole depth type variable precision seeder, cam from corresponding to the contact position of joint place, hole roller and the brush wheel of hole roller and inner walls to cam, radius increases successively, then cam under to the joint place of hole roller and inner walls, radius reduces successively.
Described type hole depth type variable precision seeder, the bristle on the brush wheel is arranged along the brush wheel circumferencial direction, and the oblique upper that is positioned at brush wheel at housing is provided with kind of a comb, and the increment of planting comb stretches between the bristle.
Its operation principle is: seeding unit is fixed on kind of the exit of case bottom, outer groove-wheel, brush wheel, hole roller is driven by sower and rotates in housing, seed at first arrives kind of the district of filling of hole roller top through kind of subchannel along with the rotation of outer groove-wheel, in the type hole that seed enters the hole of hole roller and the pin outer end of living constitutes, increase successively along with cam radius, the pin of living outwards moves under the effect of cam outline, the type hole depth shoals successively, cooperate brush wheel, only stay a seed in the type hole, along with being rotated further of hole roller, this seed is discharged by the under shed of housing, hole roller turns over the below of cam, under the effect of spring, the pin of living moves inward, and the type hole depth deepens successively, finish the one action circulation, by that analogy.
The present invention compared with prior art has following advantage:
1, by the amount of seed metering of outer groove-wheel according to seeding unit, quantitatively replenish seed to filling kind of a district, guaranteed that seeding unit remains best grain weight filling kind of a zone, reduced seed and in the filling separation process, entered the type hole because of interacting, disturbing, produce the hole, the grain weight that brush wheel need be removed in the quantitative process of clear kind is less simultaneously, is convenient to plant clearly, the simple grain rate is higher, is applicable to the precise sowing of large seeds such as corn, soybean;
2, because the cam radius variation, the type hole depth is the darkest in the filling separation process, helping many seeds enters the type hole and is stabilized in the type hole, reduce the generation in hole, shoal at the quantitative medium-sized hole depth of process of clear kind, help brush wheel and remove unnecessary seed, guarantee that a seed stays in the type hole;
3, the type hole depth is the most shallow when seeding, forces to discharge seed;
4, adopt bristle formula brush wheel to plant clearly, reduced damage ratio seed.
