Description

A kind of fresh corn thresher

technical field

The utility model relates to corn threshing equipment, in particular to a fresh corn thresher.

Background technique

There are so many corn kernels on the cob that artificial peeling can no longer keep up with the pace of the development of the times. For this reason, there are many different corn threshers on the market. Many corn threshers can only be used for threshing dry corn. The corn kernels on the dry corn cob are removed through the interaction of two twisted rollers. However, since fresh corn contains a lot of juice and is relatively soft, this kind of Corn threshers cannot thresh fresh corn, and threshing fresh corn is more difficult than dry corn. Of course, there are also some threshing machines specifically for fresh corn on the market. The main principle is to use the guide wheel to send fresh corn into the high-speed rotating blade to achieve the purpose of separating fresh corn kernels from corn cobs. However, this threshing equipment It is easy to break corn kernels, and most fresh corn threshers have large structures, expensive prices, and low penetration rates.
