The utility model discloses a high -efficient oily sha's beans harvester, affiliated technical field is agricultural machine. The utility model discloses a technique that adopts is in the spiral sieve separator is carried to the soil that utilizes receiving agencies will contain oily sha's beans, and the separation of soil screening yu reciprocal shale shaker through the spiral sieve separator finally obtains clean thorough oily sha's beans technique. The appearance of the novel transmission mode of spiral sieve separator not only is of value to the application of other crops harvester designs, has still addd a new mechanical transmission mode. Novel oily sha's beans harvester of invention utilizes the spiral sieve separator, takes independent power equipment again, has compensatied the shortcoming of current oily sha's beans harvester, has broken the design theory of traditional oily sha's beans results to make novel oily sha's beans no longer rely on in the tractor as the trouble that power supply and power transmission brought, replaced a whole set of machinery of traditional design, reached the results environment of dustproof purification, promoted the business -like interests maximize of oily sha's beans.
