Not to row corn cutting ear-picking unit

Technical field

The utility model relates to a kind of agricultural machinery, and is a kind of specifically not to row corn cutting ear-picking unit.

Background technology

Corn is one of most important in the world three generalized grain crops, about 1.4 hundred million hectares of the global corn seeding gross area.The same with other cereal crops, results also are most important cargo handling operations in the corn planting process, this not only is worth because the results link can embody a concentrated reflection of the fruit of labour, operation procedure that the more important thing is the harvest corn link is many, technical difficulty is big, and labour intensity is big, the labour drops into many, some need 1 year two batches change kind of an area, timeliness requires also urgent especially.For this reason, the corn planting big country of a lot of advanced technology has all realized the mechanization of harvest corn complete operation now substantially in the world.

China is corn planting big country, and about 2,440 ten thousand hectares of year sowing area occupies the second place of the world.The corn planting area of China mainly concentrates on Huang, the Plain to the north of the basin, Huaihe River and knob, and the overwhelming majority shows off large tracts of land contiguous plant state, very easily realizes the mechanized harvest operation.According to relevant expert's estimation, China is suitable for accounting for total sowing area 71.7% with about 1,750 ten thousand hectares of the mechanical corn seeding area of gathering in the crops; Particularly the three provinces in the northeast of China of China are located on the distant tender llanura of north pine, are the corn planting main producing regions of China, and about 6,800,000 hectares of the sowing gross area accounts for the total sowing area 28% in the whole nation.Wherein: 2,700,000 hectares of Heilongjiang Province's sowing areas, 2,500,000 hectares of Jilin Province's sowing areas, 1,600,000 hectares of Liaoning Province's sowing areas; Three provinces are suitable for carrying out with machinery about 5,600,000 hectares of the corn seeding area of harvest operation northeastward, account for 82.4% of total sowing area.

The corn main producing region that is suitable for mechanical harvest with three provinces in the northeast of China like this is an example, because weather, soil moisture content, kind, the difference of farming custom particularly, corn planting agronomy in the zone also has very big difference: not waiting of 400～700mm not only arranged on line-spacing, the difference that 200～400mm is also arranged on the spacing in the rows also exists the difference of 400～700kg on the output; But also plant between existing interplanting, the not first-class many different situations of block size, kind.This objective reality that varies of corn planting not only for the mechanization of harvest corn has proposed high requirement, has brought very big difficulty also for the large scale application of corn harvesting machine.

Exactly because this objective reality of corn planting, the present situation on product that has formed present China corn harvesting machine is: kind is a lot, and is but all very little in batches; Manufacturing enterprise is many, and scale is but all little.This present situation has caused China's corn harvesting machine whole nation recoverable amount extremely limited, and the enterprise of special manufacturing corn harvesting machine is few, the backward situation that corn crop mechanical harvest rate is extremely low.According to appropriate authority statistics in 2005, the manufacturing enterprise of national development and production corn harvesting machine is no less than 50 families, but a whole nation year production is no more than 2000; Year production and sales amount has only 8 families in the enterprise more than 50, and the highest year output only has 320; About 8600 of the total recoverable amount of the various corn harvesting machines in the whole nation, corn crop mechanical harvest rate only reaches 2.8%.This present situation is not said with the corn planting big country of advanced technology in the world and is compared, exactly with the mechanical harvest rate of domestic wheat crops reached 74%, what the mechanical harvest rate of rice class crop had reached 48% compares, gap is fairly obvious.Yet, exactly because also this present situation can be the development of China's corn harvesting machine, provide very big space, create very big opportunity.

But, the prior art state of China's corn harvesting machine, the very difficult needs that adapt to corn harvest mechanization on the horizon market fast development.One of technical problem underlying of the current existence of China's corn harvesting machine is: the existing corn harvesting machine of putting on market of China, and most types all are the corn planting line-spacings according to a certain area, correspondence has designed the swath and the corn snapping unit line-spacing of header; And equal automatic or manual line-spacing guiding mechanism of design configurations not.This version causes existing corn harvesting machine, can only be used for the harvest corn operation in a certain area of corresponding fixing design line-spacing; Can not realize not to the row harvest operation.Limited the extensive adaptive capacity of corn harvesting machine greatly, inconvenience is difficult to expand the scale of production in sales promotion on a large scale.
