4YZT-7/8 Self-propelled Corn Grain Harvester

ProductIntroduction：

The equipment can be hung with 7-row or 8-row corn header with different line spacing as well as rigid wheat header with cutting width of 4.57m and flexible soybean header with different cutting widths. With the world's advanced full-axial flow threshing and separating roller technology, the equipment can complete harvesting, threshing, cleaning and separation, as well as unloading and conveying of corns and other crops in one-stop operation. By changing different threshing rollers, separating devices and harvesting headers, the equipment can realize mechanized operation of wheat, rice and other crops, and features one-machine for multi-purpose, high cost performance, strong adaptability, high operation efficiency, low damage rate, small total loss rate, good harvesting effect, etc.

Product Features：

1.The equipment adopts the full-axial flow double threshing and separating roller technology, and the threshing and separating roller is composed of two parts, namely, the threshing zone and the separation zone. The materials are firstly rubbed and combed in the threshing zone, then rotated and conveyed to the separation zone for separation to realize multi-stage threshing and multi-stage separation, with small impact and low damage rate to crops as well as high operation efficiency. Besides, it is not easy to get blocked when harvesting moist crops.

2.The cleaning system adopts the straight-board volute blower with adjustable speed and the double-layer scale screen and lengthened tailings screen with adjustable air volume and angle. The cleaning area is big and the cleaning effect is good.

3.The roller adopts the stepless speed changing structure for speed adjustment, which has a large speed adjustment range to meet the harvesting requirements of all kinds of crops.

4.Key working components are equipped with electronic sensors to monitor the operation of key components of the harvester in real time, and the rear-view system is equipped to provide a powerful guarantee for the good driving of drivers.

5.The bridge uses the enhanced floating feeding roller bridge, which can realize rapid hanging to the header, with good universality, simple operation and reliable hanging.

6.The walking system adopts the hydrostatic drive technology, and the power output adopts the transfer case design, with simple structure and low fault rate.

7.Equipped with an open increased grain tank and a high-level hydraulic unloading grain cylinder, the equipment can unload grain at a high height and fast speed.

8.The same main machine can realize the free switching between the full-axle flow threshing and separating roller technology and the shear flow threshing roller and separator riddle separating device technologies, which is convenient to change and features one-machine for several purposes, high performance cost ratio and strong adaptability.

9.The 8-row corn harvesting header can realize one-click button bidirectional folding, with good road passage capacity.

10.The equipment can be equipped with the optional 635mm wide rubber halftrack to increase the ground contact area, reduce the vehicle ground pressure and improve the vehicle passage capacity. When working on the muddy ground and other severe working conditions, the equipment can normally conduct harvesting operation, reduce the compaction degree of soil, protect c*ted land, effectively reduce fuel consumption during lａnd preparation and c*tion in later period, save energy and reduce cost.
