Abstract
The utility model provides a pneumatic seeder which is composed of a frame, a ditch opener 4, a seed discharger, a land roller 5, a covering shovel 6, etc., and the ditch opener 4, the seed discharger, the land roller 5 and the covering shovel 6 are orderly arranged on the frame 14 from front to back. The utility model is characterized in that the seed discharger is composed of a seed chamber 3, a seed discharging disk 12 arranged in a pneumatic chamber 2, etc. The negative pressure of the pneumatic chamber 2 is formed by a blower 1 through an air pipe 10, and a seed scraper 11 and a seed conveying pipe 13 are arranged on the seed discharger; a fertilizer application ditch opener 7 and a fertilizer discharger 9 are arranged in front of the seed discharger on the frame 14, and the drive of the seed discharger and the fertilizer discharger 9 is realized by a ground wheel 15 through a chain 16.
Description
Technical field
The utility model relates to farm machinery, and a kind of seeding apparatus that is applicable to precise sowing is provided especially.
Background technology
Along with the development precise sowing technology of agricultural production has become one of comprehensive technical measure of agricultural modernization, realize 1,000 ten thousand mu precise sowing area according to the Tenth Five-Year Plan Period that requires of Liaoning Provincial Party committee, provincial government.Our province is precision planter research province relatively early, but the overwhelming majority is large and medium-sized tractor, and be the supporting precision planter of small tractor seldom.Because the existing production system in our province rural area, the tractor with small four wheels recoverable amount is huge in addition, studies to the supporting precision planter of tractor with small four wheels to have good development prospect.According to the requirement of Provincial Party committee, provincial government, Tenth Five-Year Plan Period needs surplus the supporting facility of tractor with small four wheels 20000.The investigative technique of this machine has province's kind, economizes advantages such as soil, stable yields, volume increase.Economic benefit and obvious social benefit.
Summary of the invention
The utility model provides a kind of aspiration seeding apparatus (Fig. 1) to be made up of plough 4, seeding unit, packer 5 and covering device 6 etc. that frame and front and back are contained on the frame 14 successively, it is characterized in that seeding unit is made up of seed-box 8 and seed plate 12 grades that are contained in 2 li of air-suction chamber.The negative pressure of air-suction chamber 2 is formed by airduct 10 by blower fan 1.Seeding unit also is furnished with seed scraping device 11 and grain tube 13.Applicator boot 7 and fertilizer apparatus 9 also can be housed before the seeding unit on the frame 14.The driving of seeding unit and fertilizer apparatus 9 is realized by chain 16 by land wheel 15.
During work, land wheel 15 drives fertilizer apparatus 9 and seeding unit by chain 16, and fertilizer and seed are entered in fertile ditch and the kind ditch.Applicator boot 7 is preceding, seed opener 4 after, packer 5 is pressed into 13 li seeds that fall of grain tube on the moistening solid kind bed, guarantees that seed has abundant germination and growth moisture.By covering device 6 soil is covered with subsequently.
This device adopts air-suction seeding unit, its operation principle is: air-suction chamber 2 produces negative pressure by the high speed rotating of blower fan 1, seed plate 12 separates air-suction chamber 2 as rotating seal portion with seed chamber 3, seed chamber 3 communicates with atmosphere, has just produced pressure differential in the suction hole both sides of seed plate 12 like this.Seed plate 12 is sent seed into grain tube 13 and is fallen into bottom of trench under action of pressure.Seeding unit is provided with zigzag seed scraping device 11, adjusts its position, can wipe unnecessary seed off, guarantees precise sowing.

Embodiment
Embodiment 1
The aspiration seeding apparatus of the compositions such as seed-box 8, air-suction chamber 2 and grain tube 13, packer 5 and covering device 6 and blower fan 1 of land wheel 15, plough 4, seeding unit is housed before and after on frame successively, be furnished with seed plate 12 and seed scraping device 11 in the seeding unit, packer 5 is wheeled, and covering device 6 is disks of tiltably-mounted.
During work, blower fan 1 high speed rotating, produce negative pressure, pass to air-suction chamber 2 by airduct 10, seed is drawn onto on the seed plate 12 from seed chamber 3, and seed scraping device 11 is wiped unnecessary seed off, when the part in the seed-bearing hole of suction of the seed plate 12 that is driven by chain 16 by land wheel 15 forwards lower window to, seed just falls from seed plate 12, enters in kind of the ditch through grain tube 13.Press wheel 5 is pressed into the seed that falls in the grain tube on the moistening solid kind bed, by two disk coverers 6 soil is covered with subsequently.
Change the seed plate 12 of different hole counts and the speed ratio of change chain gear transmission and can regulate the cave distance.
The aspiration seeding and fertilizing device of the compositions such as seed-box 8, air-suction chamber 2 and grain tube 13, packer 5 and covering device 6 and blower fan 1 of depth measurement applicator boot 7, fertilizer apparatus 9, land wheel 15, plough 4, seeding unit is housed before and after on frame successively, is furnished with seed plate 12 and seed scraping device 11 in the seeding unit.
During work, land wheel 15 is by chain drive fertilizer apparatus 9, fertilizer is entered Fei Gouli, and blower fan 1 high speed rotating produces negative pressure, pass to air-suction chamber 2 by airduct 10, seed is drawn onto on the seed plate 12 from seed chamber 3, and seed scraping device 11 is wiped unnecessary seed off, when forwarding lower window to by the part of land wheel 15 by the seed-bearing hole of suction of chain-drive seed plate 12, seed just falls from seed plate 12, enters in kind of the ditch through grain tube 13.Packer 5 is pressed into the seed that falls in the grain tube on the moistening solid kind bed, by covering device 6 soil is covered with subsequently.
Change the seed plate 12 of different hole counts and the speed ratio of change chain gear transmission and can regulate the cave distance.
Line-spacing, cave distance, defertilizing amount, fertilization depth and the trench digging degree of depth, sowing depth, suppression intensity and thickness of earth covering all can be adjusted.This device is best suited for sowing corn and soya bean.Compare with general type of seeding, can save seed more than 70%.
