An adjustable double-row maize harvesting
machine header comprises a transmission unit, a left header unit and a right header unit. The transmission unit comprises a power input wheel, a
drive wheel, a driven wheel, a left header unit power input wheel and a right header unit power input wheel, the power input wheel and the
drive wheel are arranged on a first transmission shaft, the driven wheel is arranged in the middle of a second transmission shaft, and the left header unit power input wheel and the right header unit power input wheel are arranged at the two ends of the second transmission shaft respectively. The
drive wheel is matched with the driven wheel. The second transmission shaft is a hexagonal transmission shaft. The left header unit and the right header unit respectively comprise three millet dividing covers, the low portions of every two adjacent millet dividing covers are provided with harvesting units, and the left header unit and the right header unit are respectively and movably connected to a
machine frame. The position, relative to the right header unit, of the left header unit can be adjusted, the adjustable double-row maize harvesting
machine can adapt to the inter-group large space in a high
photosynthetic efficiency planting method, the high efficiency mechanical harvesting is achieved, harvesting cost is reduced, and the application and popularization of the high
photosynthetic efficiency planting method are facilitated.
