For example, utility model patent CN2247412Y discloses a harvester header frame including left and right The front beam, the header rear panel, the upper beam, the suspension pipe and the header outlet, wherein the left and right side panels are a whole panel structure, and the header outlet is located at the right rear of the entire header; the invention patent CN103828540B discloses a combine harvester The header includes a dustpan-shaped header frame, a cutter at the mouth of the dustpan, a reel at the front and upper side, a header auger at the rear of the dustpan, a reel strut that spans the frame and is supported at the rear and upper part of the frame, and The transmission mechanism, its conveying chute is located at the left rear of the header frame. This arrangement (the conveying trough is offset on the left rear side of the header) makes the whole header form a cantilever structure with unequal arms on the left and right with the conveying trough as the fulcrum. The left and right sides of the existing harvester header frame are symmetrical structures, and the two sides are usually formed by tailor-welding of profiles and steel plates of the same specification, that is, the left and right rigidity of the header frame is the same. When the combine harvester is actually working, the vibration of the vertical cutter on the right side of the header is significantly greater than that on the left side, resulting in a significant increase in the loss of the vertical cutting on the right side, making it difficult to divide the crops.
