4YZP-4 self-propelled corn harvester (medium return, peeling, bract crushing)

This machine can simultaneously complete four rows of corn picking, peeling, bin collection, and crushing and returning operations; Adopting a mechanical continuously variable transmission walking system; By applying internationally advanced electromechanical, optical and hydraulic integration technology, advanced functions such as automatic monitoring and sound and light alarms have been achieved; Spiral tendon harvesting technology combines elasticity and compulsion, effectively reducing the rate of ear loss; The combination of a front-end cutting machine and a mid mounted crushing and returning machine results in better straw crushing efficiency; The peeling machine adopts a combination of high and low rubber peeling rollers and rubber toothed star wheels, with high peeling rate and low crushing rate. It is also equipped with a fruit ear and bud shredding device, a vibrating cleaning screen, and a cleaning fan, which thoroughly shreds the buds and leaves, and has low grain loss rate and impurity content; The driver's cabin adopts ergonomic design, and air conditioning is optional in the driver's cabin, providing a comfortable operating environment. The returning machine can add a gathering machine to achieve straw crushing and gathering function.
