Description
Technical field
The invention belongs to agricultural mechanical field, particularly a kind of de-ear harvesting bench of corn comb with anti-blocking pre-branch function.
Background technology
Corn is one of Three major grain crops of China, and within 2012, China's corn seeding area is 5.24 hundred million mu, and corn yield is 20,812 ten thousand tons, and the output of corn has exceeded paddy rice becomes the first cereal crops of China.Therefore advance Maize Production mechanization for Ensuring Food Safety, promotion increasing peasant income, be significant.Harvest corn, as last link in Maize Production process, occupies critical role in Maize Production process.When harvest corn, in the three autumn jobs as harvesting, tilling and planting time, labour intensity is large, need to take a large amount of labours, and development maize harvesting mechanization is the certainty of agricultural production.
Because China's corn planting region is large, corn planting pattern is varied, comprises ridge culture, flat work, interplanting etc.The Northeast's part adopts the corn planting pattern of large-ridge double-row, and between its ridge, line-spacing is 720mm, and on ridge, line-spacing is 420mm.The corn planting pattern of large-ridge double-row can meet the agriculture requirement of the two strain density plantation of corn large-ridge double-row seeding operation, and between line-spacing increase, large-ridge double-row expert strain, dislocation is planted, and is conducive to improve the ventilation and penetrating light face of corn, improves the photosynthesis rate of corn.Also disunity of China's corn planting line-spacing on the other hand, corn planting line-spacing has plantation from 300mm to 800mm.The disunity of corn planting pattern and Planting Row Distance, has caused the not problem to row results of corn, has increased the difficulty of harvest corn.
China's existing maize harvesting machine roll-type ceding of Taiwan and board-like ceding of Taiwan line-spacing are fixed, need to be to row results in the time of harvesting corn.Due to the disunity of cropping pattern and corn planting line-spacing, in harvest corn process, maize harvesting machine may push over milpa, causes damage.
In the de-ear-picking unit principle of corn comb, can carry out not to row results.But in the time of harvest operation, the tensile force at stem stalk knot fringe position place is comparatively weak, and when work, stem stalk is easy to produce and fractures.The stem stalk that the de-harvesting cylinder of comb is easily fractureed is wound around, and affects the effect of harvest operation.On the other hand, if milpa is positioned at the tip of broach bar, when results, broach can touch milpa, and milpa is easy to be pushed over cause damage.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of being applicable to the corn of the anti-blocking pre-branch of having of row harvest operation function not to be combed to de-ear harvesting bench in harvest corn process, it can realize the not operation in lines of harvest corn, reduce winding and obstruction in the de-results process of corn comb, avoid broach in results process milpa is pushed over and cause damage.
