Problems solved by technology

However, such a structure increases the complexity of the equipment structure on the one hand, and increases the manufacturing cost of the equipment on the other hand.
At the same time, the adjustment mechanism needs to adjust the opening of multiple cleaning sieve plates at the same time. For the cleaning device with a wide width or a large number of pieces, it is difficult to guarantee not only the reliability, but also the uniformity and accuracy.

Abstract

The invention relates to an adjustable type cleaning sieve. A sieve sheet group (422) of the cleaning sieve (42) consists of a sieve sheet fixing strip (422a), a fixing sieve strip (422b), a movable sieve strip (422c), a sieve sheet movable strip (422d) and the like. The invention also relates to a combine harvester with the cleaning sieve. The cleaning sieve has the advantages that the additional adjusting mechanism is not needed, and then the opening degree of the cleaning sieve plate can be accurately adjusted; the structure is simple, the operation is convenient, and the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to a cleaning sieve of a combine harvester, in particular to a cleaning sieve which can adjust a cleaning plate without adding elements. It also relates to a combine harvester including the sieve. Background technique [0002] With the progress of society and the development of science and technology, more and more machinery and equipment are applied to agricultural production, and the combine harvester is one of them. The combine harvester can complete the harvesting, threshing, separating the stems, removing debris and other processes of cereal crops at one time, and directly obtain various corresponding finished or semi-finished crops from the field. [0003] There is usually a cleaning device in the combine harvester, which screens the threshed grains under the action of the fan and the vibrating screen, discharges the fine straw out of the cleaning mechanism, and selects the qualified grains and sends them to the grain unloa...
