Wheat threshing and separating integrated equipment and working method thereof

The invention discloses wheat threshing and separating integrated equipment and a working method thereof, and particularly relates to the technical field of threshing and separating equipment.The wheat threshing and separating integrated equipment comprises a machine body, a sliding groove is formed in one side of the outer surface of a cylinder, and the outer surface of a threaded rod slides on the inner wall of the sliding groove. When the machine body is used for separating wheat, a collecting device can be placed below an output pipe to collect wheat grains, and wheat output through the output pipe can move in a cylinder and a sliding cylinder; wheat can be guided and protected in the falling process through a cylindrical barrel and a sliding barrel, the situation that wheat is splashed to the position outside the position under an output pipe to be inconvenient to collect is avoided as much as possible, and a threaded rod is pushed to slide on the inner wall of a sliding groove so that the sliding barrel
