Description
Technical field
The utility model relates to a kind of farm machinery, particularly a kind of straw chopping and returning self-propelled corn combined harvester.
Background technology
According to statistics, at present in China, corn is the staple food crop that is only second to wheat, and cultivated area is big, accounts for 21.1% of national total cultivated area, and the annual production of corn reaches 1.15 hundred million tons.In recent years, along with country continues to increase the input of agricultural production, the mechanization degree of China's Maize Production constantly increases.Whole ground, sowing, intertill and clean tillage, topdress, production link such as threshing all realizes mechanization substantially.But the heaviest link of manual labor in the Maize Production---results are but still based on handwork.Artificial results appropriation of labour power is many, and labour intensity is big,
Up to the present, the new reaping machine product that the unit of each maize harvesting machine of China releases is existing more or less a hundred, although through for many years effort, these types are still immature, and subject matter can be classified as following 2 points:
(1) poor reliability, operating speed is low, and loss is big, uses uneconomical.Its main cause is: these types are mostly with reference to the old model of the former Soviet Union, as Hull pine-2000 type, because the development time of these types early, its transmission and running gear are the mechanical type system, and the corn combined harvester link is many, cause walking and transmission system too complicated, therefore increased the fault rate of mechanical system greatly.And because the agronomy of China's corn planting and results has particularity, and the maize harvesting machine manufacturing enterprise of China is owing to lack research and development strength and research technique, can't carry out controlling suitable improvement to domestic facility because of ground, not acclimatized mostly when this has just caused external type to use at home.
(2) the facility operation quality is poor, and clogging is serious, the cleaning difficulty, and efficient is low.
Because there is very big difference China's maize planting agronomy and other corn main producing region (as the U.S., Russia, Canada, Australia etc.) in the world, be maize planting line-spacing or spacing in the rows all much smaller than other country, the milpa in the unit are, the quantity and weight of fruit ear all are much higher than other Maize Production state.Feeding Capability Requirement during therefore to the work of machine is higher.
In addition, during China harvest corn, the moisture content of seed is higher, so various places require harvesting corn fruit ear (small number of users requires the results seed) mostly, and the fruit ear of results need just can carry out threshing operations through after the long airing.Simultaneously, be subjected to the restriction of China's grain seeding technique, clear up when the land surface behind the harvest corn needs the utmost point, in order to avoid influence next seeding operation.
Therefore, the corn combined harvester technological requirement of China: in the results fruit ear, the bract of fruit ear outer wrapping is divested (making things convenient for airing); And after plucking the fringe end, remaining stalk is handled.For this reason, the corn combine of China is compared with external similar facility need increase corn peeling and two operations of straw-returning, reduces the threshing and cleaning operation, and making task difficulty and obstruction probability is relative increases.
