Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a bean threshing and straw crushing device. Background Art

[0002] With the development of industrialized agriculture, large harvesters have made great progress, and various types of harvesters have emerged in an endless stream, which has greatly improved the progress of agricultural mechanization in my country and promoted the progress of large-scale agricultural planting in my country. Various beans, such as soybeans, broad beans, and mung beans, are dried for several days after harvesting to evaporate the moisture before threshing.

[0003] Patent No. CN202320087943.7 discloses a bean threshing and straw crushing equipment. A dust exhaust port is added to the front top of the screening box.
