technical field

The utility model relates to the field of agricultural machinery and equipment, in particular to an edible bean combine harvester.

Background technique

At present, the planting area of edible beans in my country exceeds 100 million mu. However, due to the large variety of edible beans, the main varieties include mung beans, adzuki beans, kidney beans, broad beans and peas. The harvest of edible beans is still dominated by manual harvesting. Most of the combine harvesters existing in the prior art are rice and wheat combine harvesters. This harvester uses a cylinder with spikes to beat the rice and wheat plants, so that the rice and wheat grains fall off, but the grains of the edible beans are wrapped. Inside the pod, this regular slapping is difficult to completely strip the kernels out. On the other hand, the rice-wheat combine harvester generally uses the auger to transport the detached rice and wheat grains, but the grain size of some edible bean grains, especially the large-grained broad beans, is much larger than that of the rice and wheat grains, so it is easy to Damaged by the auger, resulting in a high breakage rate when the edible dried tofu grains are harvested.

Utility model content

The technical problem to be solved by the utility model is that the prior art lacks a special large-scale edible bean combine harvester, and the conventional rice-wheat combine harvester will cause incomplete grain peeling and high breakage rate when harvesting edible beans.
