Efficient conveying and cleaning equipment of combine harvester

联合收割机高效输送清选装置

Abstract

The utility model relates to efficient conveying and cleaning equipment of a combine harvester. The efficient conveying and cleaning equipment of the combine harvester comprises a threshing and separating device, a conveying device and a cleaning device. The conveying device is composed of a driving shaft, a driven shaft, gears, a chain, chain harrows and a conveying bottom plate, the driving shaft is in power connection with a power system of the harvester, the gears are symmetrically distributed at the two ends of the driving shaft and the two ends of the driven shaft, the chain is located on the gears, and the chain harrows are uniformly fixed to the chain. The cleaning device comprises a draught fan and a sieve box, the sieve box is composed of a front sieve, a middle sieve and a tail sieve, one end of the front sieve abuts against the conveying bottom plate, and the other end of the front sieve is connected with the middle sieve and the tail sieve in sequence. The efficient conveying and cleaning equipment of the combine harvester is simple in structure, reasonable in design, capable of effectively solving the problem of grain running on a slope and a steep road, high in conveying efficiency and cleaning efficiency, short in period, low in manufacturing cost and convenient to popularize.
本实用新型涉及一种联合收割机高效输送清选装置,包括脱粒分离装置、输送装置和清选装置,输送装置由主动轴、从动轴、齿轮、链条、链耙和输送底板组成,主动轴与收割机的动力系统动力相连,齿轮对称分布在主动轴和从动轴两端,链条位于齿轮上,链耙均匀固定在链条上,清选装置包括风机和筛箱,筛箱由前筛、中筛和尾筛组成,前筛的一端与输送底板靠接,另一端与中筛和尾筛顺序相连,本实用新型结构简单、设计合理,可有效解决在斜坡和陡坡路面的“跑粮”问题,输送效率高,清选效率高,周期短、制造成本低,便于普及推广。
