Description
Technical field
The utility model relates to agricultural machinery technological fields, and in particular to a kind of precise seeding machine of corn.
Background technique
Corn drill refers to that with corn seed be the seeding machinery for sowing object, according to certain line space and corn number
Amount, corn seed is equably seeded into farmland, then the farm machinery [5] buried with soil.According to working principle, precision is broadcast
Kind machine can be divided into Pneumatic precision seeder and mechanical precision drill two major classes, and from the point of view of structure type, Pneumatic seeding apparatus has
Aspirated-air type, vapour-pressure type, air-sweeping type and strength and combined type mechanically etc. are many kinds of;There are commonly vertical circles for mechanical seed sowing device
Disk side-feeding, centrifugal disc, inclined plate, nest eye wheel type and more than 30 [11] such as indent brush kind is wheeled.
At the end of the 20th century, due to the development of the industrial revolution, people have deeper understanding for mechanization production, in the past 60 years
External sowing seeds technology has fast-developing and reaches quite perfect level.In the 1960s, the U.S., Germany etc.
Developed country starts to develop a large amount of different seeders, wherein it is mechanical mainly to promote Pneumatic type precision drilling.Essence is measured by China
From in late 1970s, wherein most is from the sophisticated machine of external import or according to external machine for the research of seeder
It is copied.The eighties, Major Epidemic was half smart amount formula sowing, wherein mainly carrying out small-sized single body seeder.From 20th century 90
Age Mo, the precision planter in China gradually have preferable development, and China gradually promotes precision planter, a about more than 10
Enterprise starts to produce seeder.Domestic North China Plain area mainly uses large and medium-sized corn drill, and in hillside hilly country
It is difficult to sow, therefore devises small-sized precise seeding machine of corn.
Precise seeding machine of corn is broadly divided into two kinds at present: mechanical and aspirated-air type.Aspirated-air type precise seeding machine of corn is most
Big advantage is not damage seed, is required than less stringent in terms of seed sizes.But the components such as blower need very high essence
Degree, difficult processing, high production cost, and also the price of operation, maintenance and maintenance is very high, is not suitable for China's national situation, usually only
Developed countries use.Mechanical precise seeding machine of corn is mainly used at home.Mechanical precise seeding machine of corn
The advantages of be that structure is simple, working performance is high, and stability is high, price material benefit, low in cost, is suitable for China's actual conditions.According to cultivated
Make habit and tillage method, seeder can be divided into no-tillage seeding machine and cultivating seeder two major classes.No-tillage seeding operation is not only
It can be reduced tractor and enter field number, reduce the investment of producing cost, repeatedly rolling to soil is reduced, when shortening sowing
Between, energy consumption is reduced, and can guarantee sowing in time, to improve germination percentage, increases insemination and emergence advantage and high yield is established
Solid foundation is determined.By operation line number point, have power single line sowing machine, two row seeders, four row seeders, six row seeders and
Multiplerow seeders more than six rows.
Since the maize production phase is short, yield is high, and plantation is convenient, and survival rate is high, and quality is good, adaptable, at present at me
It is number three in state's cereal, is only second to paddy and wheat, furthermore corn, which is also used as the feed of livestock or deep processing, becomes each
Kind product, therefore corn has very high food value and economic value.It is extremely important to sow growth course entire for corn,
However not only working efficiency is low by artificial seeding, but also cost of labor is also gradually increasing, so there is weight using Mechanization sowing
Big meaning, Mechanization sowing have not only liberated productivity, have also greatly improved working efficiency, germinate for morning, strive accumulated temperature, wound of striving for high yield
Condition is made.
Corn mechanization seeding machinery used at present belongs to a kind of extensive style sowing, cannot be directed to the actual growth of corn
State is sowed to adjust spacing, distance and depth when plantation, can only say and save a part of labour to a certain extent, still
According to being more advantageous to for growth of seedling angle, also there is certain gap.
Precision planter refers to the agricultural machine that a quantity of seeds can be sowed according to certain spacing, distance and depth
Tool has the advantages that save and works, is time saving and energy saving, is more advantageous to the growth of seedling.Plantation efficiency how is improved, people is mitigated
Power labour, realizes maize fine sowing, for realizing that the modernization sowing of corn is of great significance.
Summary of the invention
To solve drawbacks described above, the purpose of this utility model is to provide a kind of precise seeding machine of corn, structure novel is closed
Reason, control system is accurately reliable, can autonomous operation, sowing uniformly, avoids occurring in seeding process serious broadcast leakage and replay
