Description
Technical field
The invention belongs to agricultural seeder machinery, particularly a kind of air-breathing precise seed sowing device.
Background technology
Precise sowing is a kind of advanced person's a kind method for planting, and it has province's seed, economizes remarkable advantages such as thinning worker, volume increase, raising crop quality.Become at present the main mode of countries in the world various crop field planting.Continuous development along with modern agricultural technology, especially the continuous maturation of seed engineering technology, huge variation has taken place at the planting requirement and the growing environment in field in crops, existing most field crop planting patternss are from traditional drilling, bunch planting or semi-accuracy seeding, and progressively the planting patterns to precise sowing develops.The crop of Precision Seeding at present has: various crop such as corn, soybean, beet, sunflower, wheat, paddy rice.
The key that realizes the precise sowing technology is that can seeding unit provide uniform seed flow.External precise sowing mainly adopts pneumatic type (air-blowing, aspiration), and the seeding unit of use mainly is single-deck or drum-type, and is mainly used in corn, Soybean and Other Crops Precision Seeding, and crops such as paddy rice, wheat are adopted the drilling technology always.China just began one's study and promotes the precise sowing technology from early 1970s, and present precision seeder kind is a lot, but these seeding units are difficult to satisfy paddy rice, wheat, soybean and band bud crop precise sowing thereof.The air-suction seeding unit of using is all single-deck formula, drum-type or plate armature at present; The combined sucker formula wheat precision seeder of the aspiration two-layer cylinder formula rice seeder of the combined sucker air-suction seeding unit of the serial air-suction type accurate sower that Wafangdian, domestic Liaoning precision sower Manufacturing Co., Ltd produces, Xibei Univ. of Agricultural ﹠ Forest Science ﹠ Technology's development, the development of Guangxi Beihai City Agricultural Mechanization Inst., China Agricultural University's development etc., also be single-deck formula or drum-type, the tortuous line of helicla flute that has complexity in its structure forms respectively inhales kind of a district, clear kind district and defeated kind of district, complex structure, the sowing crop is single.The single-deck air-breathing precise seed sowing device that Jilin University makes, by being arranged on the supercentral feed shaft of gas chamber shell by bearing, being installed in the seed plate on the feed shaft and buckling at the kind chamber housing of gas chamber shell one side and be arranged on seed plate and plant clear kind of device in the kind chamber that forms between the housing of chamber and stir kind of a wheel and form, its shortcoming is that dropping frequency is low, is not suitable for the high speed operation of granules such as soybean, wheat, paddy rice apart from crop.
Summary of the invention
The object of the present invention is to provide a kind of a kind of double-disc air-suction type precision seed sowing device that can satisfy granule distance, irregularly shaped seed agriculture requirement, low to overcome the dropping frequency that present single-deck air-breathing precise seed sowing device exists, be not suitable for the shortcomings such as high speed operation of granule apart from crop.
Double-disc air-suction type precision seed sowing device of the present invention is formed as follows: it comprises that the bottom has the discoid gas chamber shell that circle lacks, be arranged on the supercentral feed shaft of gas chamber shell by bearing, be installed in the seed plate on the feed shaft, buckle at the kind chamber of gas chamber shell side housing, be arranged on clear kind of device in the kind chamber that forms between seed plate and the kind chamber housing and stir kind of a wheel, described seed plate is provided with circumferentially uniform, suction hole corresponding to ring-shaped groove air chamber on the gas chamber shell end face, it is characterized in that, on the both sides end face of described gas chamber shell respectively correspondence be provided with described ring-shaped groove air chamber, the first half of this both sides ring-shaped groove air chamber interconnects, and is connected with the bleeding point of gas chamber shell upper end; Two described seed plates split the both sides at gas chamber shell, and among making two suction holes on the seed plate heart not on same axis; Two described kind of chamber housings buckle the both sides at gas chamber shell respectively, and two described stirs on the end face that kind of wheel is installed in two described seed plates respectively.
Double-disc air-suction type precision seed sowing device of the present invention not only is specially adapted to the precise sowing of rice paddy seed, also is applicable to the precise sowing of wheat, soybean, corn and seed with sprout thereof.Because two seed plates are set, and the certain angle that staggers alternately equably of the suction hole on two seed plates, dropping frequency significantly improves, and is adapted to high speed operation sowing, can guarantee the requirement of crop grain distance and sown scope; Shared air chamber owing to forming between two seed plates and housing makes the seeding unit more compact structure, has alleviated the weight of structure simultaneously.
