Abstract
The invention relates to a directional and positioning seed metering device of a precise seeding machine of corn, which comprises a seed conveying hopper, a seed sliding board, an auxiliary guiding mechanism and an upper cover, wherein the seed sliding board is composed of a sliding board and a pair of side baffles arranged on two sides of the sliding board. The width d1 of the sliding board is the largest width of corn seeds, an included angle alpha of the sliding board and the horizontal plane is 19 degrees to 23 degrees, the auxiliary guiding mechanism is composed of an adjusting bolt and two guiding plates with the interval as d2, and d2 ranges from 11 mm to 15 mm. The directional and positioning seed metering device of the precise seeding machine of the corn has the advantage that the seeds can be arranged in a seeding preparing ditch in the same direction so as to achieve rational close planting and stable and high yield.
Description
Technical field
The present invention relates to a kind of precise seeding machine of corn orientation, positioning seed metering device.A kind of and the matching used facility of precise seeding machine of corn.
Background technology
The emphasis of corn drill design is always all in discharge capacity and cave distance, early stage corn drill is drilling machine, solve corn seeding machineryization problem, the corn seeding drill designed afterwards, solve and determine spacing in the rows sowing problem, but always orientation, the orientation problem of nobody's business seed, also nobody studied this problem.Recent years, nearly especially 2 years, for solving corn dense planting High-Yielding, many agricultural experts are according to the growth in " one " font always after being unearthed of corn growing season leaf, and its to germinate be parallel flat to, the characteristic that grows perpendicular to the major diameter of seed, many agricultural experts have carried out the artificial malaria sowing test of multiple spot, achieve gratifying effect of increasing production.But artificial malaria sowing needs a large amount of labours, and sowing efficiency is too low, and speed is too slow.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of the precise seeding machine of corn orientation, the positioning seed metering device that solve corn dense planting High-Yielding.
The technical solution adopted for the present invention to solve the technical problems:
The present invention includes defeated kind bucket, seed slide, auxiliary guide mechanism and upper cover; Described seed slide is made up of slide plate and the side dams being positioned at its both sides, the width d1 of described slide plate is the Breadth Maximum of corn seed, the angle α of described slide plate and horizontal plane is 19 ~ 23, and the Breadth Maximum of described corn seed is the Breadth Maximum of the large end of the shape of a hoof;
The sowing port of described conveying bucket faces described slide plate;
Described upper cover is parallel with slide plate, and is fixed on the top of a described side dams;
Described auxiliary guide mechanism is that two guide plates of d2 and adjusting bolt form by spacing; Described two guide plates are fixed on the end of slide plate; Described adjusting bolt penetrates the hole be arranged on two guide plates; Described d2 is 11 ~ 15mm.
The present invention also comprises the postive stop baffle parallel with described slide plate, and the two ends of described postive stop baffle are connected with auxiliary guide mechanism with described conveying bucket respectively, and the distance h between described postive stop baffle and slide plate is the Breadth Maximum of corn seed.
A side dams of the present invention and slide plate and upper cover surround cavity shape of cross section be inverted trapezoidal shape.
Operation principle of the present invention is as follows:
The present invention is based on corn seed germination be unearthed after, its each strain leaf all in perpendicular to corn capable to, in the rule of horizontal " one " font growth, the center of gravity of corn seed is utilized to broadcast automatic direction regulating in ditch sliding process to standby in seed slide, the major part of corn seed horseshoe type is made automatically to slip into for broadcasting in ditch downwards, for indivedual incorgruous seed after being slipped to bottom of trench, then make its automatic queuing by the guiding of auxiliary guide mechanism, to improve orientation, location rate.
The invention has the beneficial effects as follows and can be arranged in for broadcasting in ditch by equidirectional for seed, to realize rational close planting, reach stable yields height and receive.

The sowing port of described conveying bucket 1 faces described slide plate 2;
Described upper cover 4 is parallel with slide plate 2, and is fixed on the top of a described side dams 3;
Described auxiliary guide mechanism is that two guide plates 6 of d2 and adjusting bolt 7 form by spacing; Described two guide plates 6 are fixed on the end of slide plate 2; Described adjusting bolt 7 penetrates the hole be arranged on two guide plates 6; Described d2 is 11mm.
The present embodiment also comprises the postive stop baffle 5 parallel with described slide plate 2, and the two ends of described postive stop baffle 5 are connected with auxiliary guide mechanism with described conveying bucket 1 respectively, and the distance h between described postive stop baffle 5 and slide plate 2 is the Breadth Maximum of corn seed.
A described side dams 3 and slide plate 2 and upper cover 4 surround cavity shape of cross section be inverted trapezoidal shape.
The present embodiment through bench test, directed, location seeding qualification rate >=80%.
The course of work of the present embodiment is as follows:
After seed enters defeated kind bucket 1 by former precise seeding machine of corn grain tube, drop on slide plate 2 by the free tuning of sowing port of defeated kind bucket 1, then seed utilizes centre-of gravity shift automatic queuing to slip into for broadcasting in ditch, slips into the standby seed broadcasting ditch, carry out tuning by auxiliary guide mechanism to irregular individually.Distance d2 between two guide plates 6 of auxiliary guide mechanism, can adjust by adjusting nut 7 according to the width of seed.
Embodiment 2:
Embodiment 2 α=23 as different from Example 1, d2=15mm.
Embodiment 3:
Embodiment 3 does not have postive stop baffle 5 as different from Example 1.
