Jiangsu Yucheng Dynamics Group Co., Ltd.

Guyuan brand full-feeding combine harvester (4LL-1.8YZ)

Main features:

1.       Adoption of a combinative structure mechanism of a continuously variable transmission and a special-purpose gear box and the hydraulic booster steering, which is simple and convenient and high in working efficiency.

2.       Adoption of a double-layer cutting device, which is small in feeding load, thus making it more adaptable to the requirement for reaping of higher-yield crops.

3.       Adoption of hydraulically lifted reel, which is highly efficient in collapsed crops.

4.       A combinative mechanism is adopted in the threshing, sieving and cleaning unit, which includes a combinative axial-flow cylinder, a lattice-type concave, a blowing/suction double air blower and a compound cleaning device consisting of a vibration screen and a dual-processor, which is small in loss and high in cleaning efficiency.

5.       There are such patent technologies incorporated as the threshing top-cover guide-plate angle is ganged and adjustable, a new compound radiator water-tank and a grain-unloading turnover plate hitching mechanism.

6.       Special devices are provided as required by customers, such as an operator’s cab, an unloading type grain tank and a hydraulic steering device.
