Description

A kind of high speed combine harvester

Technical field

The present invention relates to a kind of combine harvester, especially is a kind of high speed combine harvester.

Background technology

At present, combine harvester in the society roughly is divided into full feeding and partly feeds two kinds: wherein feed combined harvester entirely and the fringe head of cereal and cane are all fed sheller unit carry out threshing, its threshing and the load of cleaning are big, and power consumption is big, and stop up easily during operation; Partly feed combined harvester and clamp the cereal cane with clamping convey device, only fringe portion feeding sheller unit is carried out threshing, though reduced power consumption, the clamping convey device complex structure, productivity ratio is low, is mainly used in small rice combine.Existing combine harvester is monomotor in addition, in order to satisfy job requirements, its power is bigger, and when road walking and transition, still to guarantee road speed with large throttle, waste and the oil plant serious waste, increase user's use cost, do not met the social orientation of low-carbon environment-friendly.

Summary of the invention

Purpose of the present invention overcomes above deficiency exactly, it mainly by harvesting part, cane pulverize part, threshing part, separating part, clean partly, motivation transfer motion part and chassis running part grade and form.It is characterized in that: the ceding of Taiwan of combine harvester is divided into harvesting part and cane pulverizing part, and the harvesting part is only gathered in the first half of cereal, and the Lower Half cane is then pulverized directly pulverizing of part by cane, does not enter sheller unit; Threshing is partly adopted and two is cut the stream cut flow roller, has strengthened the threshing ability of grain header; Separating part adopts the twin shaft flow point from cylinder, has strengthened the separating cleaning area of grain header, has saved the huge straw walker of grain header simultaneously; Clean part and adopt two air channel crossflow fans and the two sieves of bidirectional reciprocating vibration, improved the effect of cleaning of grain header; Motivation transfer motion part adopts twin-engined, and sustainer is mainly used in harvest operation, and assistant engine is mainly used in walking and less important work.

Good effect of the present invention: 1) cane is pulverized that part efficiently solves that full feeding combined harvester power consumption is big, is stopped up easily during operation and half feed combine harvester clamping convey device complex structure, problem that productivity ratio is low.2) two stream, twin shaft stream, two air channels crossflow fan and bidirectional reciprocatings cut vibrate two sieve structures, have strengthened threshing and the separating power of grain header, have strengthened the separating cleaning area of grain header, have improved operation quality and the operating speed of grain header.3) major and minor engine at work separately independent, be independent of each other, not only guaranteed the results quality, and also raising greatly of operating speed, only work with assistant engine when road is walked and cut in addition, reduce fuel consume significantly, reduced user's use cost.
