Brave 4YJ-4A2 (G4) self-propelled corn harvester product introduction

■ Combination cutting platform, patented technology, can achieve simultaneous harvesting of corn ears and stems. The upper cutting platform is a new type of four row 650mm row spacing ear picking platform, which adopts a blade type stem pulling and plate type ear picking, with fast stem pulling speed and good ear picking effect; The lower cutting platform is a rolling blade type stem harvesting platform, which has good stem cutting effect, does not stick to soil during stem harvesting, and has a high effective harvesting rate for the entire stem.
Three sets of six feeding rollers are arranged, with obvious stem combing effect, dense compaction, and smooth and efficient conveying.
The stem cutting device is a combination of dynamic and fixed knives, with 24 chopping knives arranged in a double row herringbone shape. It has a small cutting angle, good separation effect, and strong throwing ability; The fixed blade can be replaced and its position can be adjusted to meet the needs of adjusting the clearance between the moving and fixed blades during harvesting operations;
■ Automatic sharpening mechanism, one click operation, automatic sharpening, meeting the sharpening needs of users during the working season and ensuring the cutting effect of stems.
Efficient acceleration mechanism, integral shell, one-piece welded impeller, 8 throwing blades arranged in a double row herringbone shape, better throwing effect and higher efficiency.
Specialized collector, with good collection effect, smooth material circulation, low energy loss, and high discharge outlet speed.
High strength, large swing angle, closed throwing mechanism, long throwing distance, high material concentration, can achieve harvesting operations from 90 °+2 ° on the left to 90 °+2 ° on the right, meeting the throwing needs of various material receiving vehicles at different heights from low to high.
Scraper chain elevator, with a lifting channel width of 600mm, offset on the right side, and uniform lifting and conveying of fruit clusters; Efficient cleaning fan+secondary stem pulling mechanism, with strong stem cleaning effect.
The peeling machine adopts five sets of peeling rollers, with good peeling effect, a peeling rate of over 95%, and a grain loss of less than 2%.
The effective capacity of the grain silo can reach 5 cubic meters, significantly reducing the number of grain unloading times per unit time and improving operational efficiency.
Specialized 1000 series gearbox, reinforced side reduction, with stronger driving force; Hydraulic front drive and mechanical rear drive can achieve one rod combination/separation rear drive; The drive wheel has a wide cross-section, high load-bearing capacity, strong adaptability to ground conditions, and better passability.
National IV 280 horsepower rear power take-off engine, with sufficient power reserve and stronger power; Adopting a dedicated intercooled integrated combination water tank with high heat dissipation efficiency; Special fireproof cover effectively prevents debris from entering the space near the engine.
Electronic control multifunctional handle, integrated armrest box, electro-hydraulic control, one click operation, can complete all actions such as driving and harvesting, greatly reducing the workload of the operator group.
