Description
Technical field
Patent of the present invention belongs to seeding technique field in the agricultural machinery, and particularly a kind of strength hill drop belongs to the improvement technology of seeding unit.
Background technology
The interrelated data statistics shows: about 3,000 ten thousand hm of the long-term cultivated area of China paddy rice
2, account for about 28% of national grain acreage; About 1.9 hundred million t of paddy gross annual output amount account for 40% of national total grain output; Whole nation paddy consumption figure per capita is 136.9 kilograms.High-quality, highly efficient and productive, develop Rice Production and accelerate its industrialization paces sustainably, guaranteeing that grain security is supplied with has become the long-term grand strategy decision-making of China.Live and transplanting is two kinds of topmost paddy rice planting patternss.Machinery is live because of having the operating efficiency height, the abridged edition saving of labor, and advantage such as easy and simple to handle receives peasant's welcome day by day.The new hybrid rice variety of cultivating of China is various, and planting area is wide, and cultivated area has accounted for more than 50% of the total cultivated area of paddy rice.Mostly existing paddy machinery formula seeding unit is hole roller formula and outer groove wheel.Like patent of invention (grant number: proposed a kind of special seeder for rice direct seeding machine CN278595C), can move the inside and outside pawl of regulating vertically, thereby adjustment nest eye length and quantity have realized paddy rice drilling and bunch planting; Its shortcoming is that every cave amount of seed metering grain number can not accurately be controlled, and the seeding coefficient of variation is bigger, and there is mechanical damage in seed.The hybrid rice seed cost that the existing machinery seeding technique all is difficult to accurately to control seed number per, hole rate is higher, seeding quantity is bigger than normal, increased, later stage agronomy management workload and cost have been increased; Be difficult to give full play to the best productive potential of hybrid rice, be difficult to satisfy current agricultural production needs.
Summary of the invention
The object of the invention is to consider the problems referred to above and a kind of precision drilling is provided and reduces the strength hill drop to the seed mechanical damage.
For realizing above-mentioned purpose, technical scheme of the present invention is:
