Description
Technical field
The present invention relates to the no-tillage seeding machines in a kind of agricultural machinery technological field, especially with regard to a kind of corn cave-applied fertilizer
No-tillage seeding machine.
Background technique
Fertilizer plays irreplaceable role in crop production, but excessive fertilization, utilization rate of fertilizer lowly constrain
The further promotion of China's Per Unit Area Grain Yield.Studies have shown that the low major reason of fertilizer nutrient utilization is considerable part fertilizer
Nutrient distribution in from the farther away soil body of root, and fertilizer by the diffusion majority on the border fertile border Xiang Feifei within 3~6cm, constrain fertilizer
Expect nutrient being absorbed and utilized by this season plant.Therefore, crops biggish for distance between rows and hills, such as corn (Planting Row Distance, spacing in the rows
Respectively 60cm, 25cm), changing chemical fertilizer row replacement is that identical, the cost-saving synergistic that fertile border space and root zone space can be achieved is applied in root zone cave
Effect is significant.
Cave-applied fertilizer implementation common at present mainly has continuity cavitation device and intermittent cavitation device.One performance
Excellent cave-applied fertilizer cavitation device requires have the features such as cave-applied fertilizer accuracy of measurement is high, cavitation is good.The principle of continuity cavitation device
It is that constantly from the area Chong Fei, capsule takes quantitative fertilizer and launches for fertile chamber on the cavitation wheel using continuous rotation, advantage is the fertilizer in every cave
The amount coefficient of variation is small, and fertilizer amount is accurate, the disadvantage is that cavitation is poor；The principle of intermittent cavitation device is to utilize outer groove-wheel fertilizer apparatus
Continuous fertilizer stream is provided, useful cam mechanism or magnet spring control baffle are opened and closed continuous fertilizer flow point inside plough
It isolates, achievees the effect that cave-applied fertilizer, advantage is that fertilization point is close from the ground, and cavitation is good, the disadvantage is that outer groove-wheel is difficult to provide
Even consistent fertilizer stream, causes every cave fertilizer amount coefficient of variation big, and fertilizer amount is difficult to essence amount and determines, and this mechanism structure is complicated, every cave
Interval time depends entirely on the response speed of mechanism, therefore with the raising of machine travel speed, cavitation is remarkably decreased.
Seed landing precision seriously affects spacing in the rows consistency, fertilizer needed in turn resulting in vine growth and development, water, heat, gas
The imbalance of supply, and the main process for influencing seed landing precision have feed mechanism for seed fill kind charge seed, seed leaves feed mechanism for seed to planting
Sub- landing, suppression of soil etc..Seed, which leaves mechanism used in feed mechanism for seed to seed landing process, at present mainly seed spout, defeated kind
Band.Seed spout be easy to cause seed to bounce, and then influences seed and land precision；Defeated kind of band can guarantee that seed is steadily accurately fallen
Into kind of ditch, but structure is complicated, expensive；In addition, turning there are also the synchronous with seeding bucket wheel of bucket wheel type seeding unit is applied to
Dynamic seeds depositing wheel can improve landing precision by reducing the height of charging seed of feed mechanism for seed.To sum up, seed spout, defeated kind of band and
Seeds depositing wheel and feed mechanism for seed or discharge plate are independent from each other components, it is meant that dispenser overall structure is bigger, longer.
Above-mentioned cavitation device there are aiming at the problem that, design a kind of corn cave-applied fertilizer no-tillage seeding machine, including cave-applied fertilizer machine
The air pressure feed mechanism for seed of structure and seed wheel and seeds depositing wheel one may be implemented every cave fertilizer amount accurate quantification capsule and take and quickly launch, at
Cave function admirable；Vapour-pressure type feed mechanism for seed simple grain function admirable, seed wheel and seeds depositing wheel one, simple and compact for structure, low level is charged seed
It improves seed and lands precision.

150mm and 150-200mm.The quantity of kind of slot 6532 is filled for the integral multiple of the quantity of fertile chamber 4462, by adjusting transmission ratio and row
The starting phase angle of fertilizer wheel, discharge plate, discharge plate and roller Synchronous Transmission, height of charging seed reduce as far as possible, and kind, cave fertilizer synchronize together
When throw fertilizer, guarantee the corresponding seed of a cave fertilizer.
When work, the discouraged plate of Archimedes spiral and discharge plate are stacked together, and fill kind of slot and Archimedes spiral loses heart
The part of slot intersection can be just adsorbed under differential pressure action with escaping air, seed fills kind of slot and the discouraged slot of Archimedes spiral
Hand over phase aperture on, since this aperture constantly moves, thus seed simultaneously by circumgyration campaign and radial direction centrifugal movement,
The extra seed that this process can inherently be such that aperture adsorbs voluntarily is fallen, and achievees the purpose that clear kind, and seed movement is to filling kind of a slot
Pressure differential collapses after distalmost end, seed is adjacent every in the small space that kind of plate is formed into two under centrifugal force and gravity, improves
Landing precision.
In addition to corn, cave-applied fertilizer of the invention is can be used in crop such as soybean, peanut, sunflower etc. of the spacing in the rows greater than 10cm
No-tillage seeding machine carries out seeding and fertilizing operation.
The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
