Dongfanghong 4YZ-3 corn harvester is a new type of corn harvester developed based on Dongfanghong 4LZ-2.5 grain combine harvester using a number of patented technologies. The machine has the advantages of compact structure, easy operation and maintenance, high passability, wide adaptability and high reliability, and has the following advantages over other domestic corn harvesting machines:
It can complete operations such as picking, transportation, packing, and straw smashing and returning to corn crops at a time, and has high efficiency.
It can achieve self-determination and has good adaptability to different row spacing and different varieties of corn.
Adopting the most advanced picking mechanism in the world, the panicle picking is fast and effortless, with less damage to the ear and less loss of grain.
The straw crushing and returning machine adopts a spiral cutting device where the moving knife and the stationary knife intersect each other, the straw is crushed shortly, and the crop remains low.
The grain granary adopts hydraulic lifting and unloading mechanism, which saves time and labor.
The dual-purpose grain box for corn and wheat is exempt from secondary replacement and disassembly, and is easy to use.
The lifting and lowering of the troughs is convenient and reliable. The unique grain tank is filled with devices to improve the working efficiency.
According to the needs of some parts of the exchange, you can harvest wheat, rice and other crops to achieve a multi-purpose machine. It has the advantages of low cost, short investment return period, and significant economic benefits.
