4YZB-3S Self-propelled Corn Harvester

ProductIntroduction：

The equipment is a corn harvesting machinery independently researched and developed by the Company on the basis of absorbing the advanced technologies of foreign core harvesters, it is suitable for the harvesting operation of corn planting patterns in different areas and can complete the whole-process harvesting operation of ear picking, conveying, bract stripping, packing and straw turnover at a time. The equipment is dedicated for harvesting corn ears, and can meet the feature requirement that the moisture content of domestic corns at harvesting are too high to thresh directly. This series of models features simple structure, convenient maintenance, perfect performance, high operation efficiency, good operation quality and other advantages. All the performance indexes of such models are up to or superior to the requirements of domestic relevant standards, and their comprehensive technical indicators rank in the leading levels in domestic similar types.

Product Features：

1.The stripping machine adopts the four-set horizontal structure, and can be equipped with one rubber roller and one iron roller or half rubber roller and half iron roller to adapt to different variety requirements, with a good reliability and high stripping rate.

2.The engine adopts 133 hp, which has a big power reserve and high operation efficiency.

3.The equipment adopts an optimized chassis structure and a driving axle with wheel-side reducer stepless speed changing, which meets the requirements of the operation adaptability and improves the operation flexibility.

4.The wheel base of this model is 1800, which meets the needs of different areas.

5.The hydraulic system is equipped with priority valve and type-5 steering gear, which enables the hydraulic system to operate at low-speed gear to achieve rapid lifting of the grain tank and header, greatly reducing the fuel consumption.

6. The smashed straw machine adopts three-blade structure, which greatly improves the returning effect; and the reasonable speed ratio of the smashed straw machine avoids high-speed gear operation and reduces fuel consumption.

7.The increased grain tank reduces the number of unloading times and improves the operation efficiency; in addition, the grain tank is designed with a grain baffle to ensure unloading without drops.

8.The stem pulling roller of the header is of cylindrical six-edged type, with good stem pulling effect.

9.This model is innovatively designed with four drives, which are installed in the middle for field returning; and the increased rear drive axle drive gearbox ensures reliable driving.

10.The increased grain cleaning fan for vibrating screen grain recovery cleans the recovered grains and reduces the number of grain receiving times, which improves the operation efficiency.
