Description

Corn husker with variable arrangement of husking rollers

Technical Field

The utility model relates to a corn husker used on a corn harvester.

Background

At present, most peeling machines in the market are matched with a corn harvester for use, firstly, the peeling machines configured on the corn harvester have two peeling roller arrangement forms, namely a groove type arrangement form and a horizontal arrangement form, the peeling roller arrangement forms of the peeling machines in northeast and northwest areas are mostly horizontally arranged in general, and the peeling roller arrangement form of the original product is mostly groove type arrangement, mainly because the crop planting in the northeast and northwest areas is single season planting, the corn ears are dry when the corn is harvested, the bracts at the head of the corn ears are already fried, and the peeling is relatively easy; in the prior area, crops are planted in two seasons of one year, the ears are green when the corns are harvested, the bracts are wrapped very tightly, the husking is difficult, from the aspects of market research and service, in recent years, the harvest time of the northeast area is advanced, the ears are harvested when the ears are green, and thus the problem of low early-stage husking rate exists, so that the huskers with the groove type arrangement are needed, the ears are dry when the ears are harvested, and then the huskers with the groove type arrangement form are adopted, the seed loss is large, the huskers with the husking rollers in different arrangement modes are independently designed according to different areas and different corn varieties easily cause the increase of the production cost, namely, a plurality of corresponding molds and detection tools are needed, the husking requirements of different areas cannot be met in the sale and use process, and the arrangement form of the husking rollers cannot be timely adjusted according to the husking degree and the maturity of the corn (different corn varieties have different difficulty degrees) in the husking process, i.e. the peeling effect cannot be immediately improved.
