Description

A pod thresher

technical field

The utility model relates to the field of agricultural equipment, in particular to a bean pod thresher.

Background technique

At present, small pod threshers have the characteristics of small size and low price, and are generally used by bean farmers and scientific research units to thresh small batches of pods. Most of the small pod threshers in the prior art are similar to the structure disclosed in the Chinese patent "Bean Sheller" with the publication number CN208676305U. The basic principle is to place the pods between the shelling roller assembly and the shelling mechanism. Kneading, so that the bean grains and the bean shell are separated, and both the bean grain and the bean shell leak out from the gap of the shelling mechanism. In practical applications, such small pod threshers generally have the disadvantage of insufficient sales. The fundamental reason is that the shelling mechanism has a row of evenly distributed grid bars, and the gap between these grid bars is fixed. The gap in size can only have a good threshing rate for pods of a certain size. Once the variety of beans grown by the user changes and the size of the pods changes, the threshing rate of the thresher will decrease significantly. As ordinary farmers, it is impossible to configure different threshers for different varieties of beans, which leads to the fact that small pod threshers cannot be welcomed by small-scale farmers, nor purchased by large-scale bean processing factories.
