4YZB-8 Self-propelled Corn Combine

Specifications

Properties:
1. Asymmetrical row spacing corn harvesting shears is adopted, so that harvesting operation is not limited by row spacing.
2. Our corn combine can connect with silage corn harvesting mow platform S-2200 to harvest corn for silage so corn combine can have two usages.
3. The machine is driven by 1000 series speed changing box, which is easy and flexible to operate.
4. The machine possesses specially designed device for cutting up corn stalk and return it to original field and its cutting quality is high and power consumption is low.
5. Big-volume and rolling-over cluster box driven by hydraulic pressure is adopted to greatly reduce the times to unload the grain and improve work efficiency.
6. Message in the electronic monitoring system is shown on liquid crystal; so that the volume of it can be small enough but its precision and reliability have been improved.
7. Loss rate of kernel and cluster is low, for traveling sieve can recover lost kernel.
8. Peeler can work to peel leaves as much as possible while rate of broken corn is reduced to least possible. 
III. Properties:
1.Engine power: 117.6kW(160 horsepower);
2. Operational width: 2.6 m;
3. Weight of the whole machine (harvesting both spike and stalk): 10.16 tons
4. Operational model: self-propelled forage row independent harvesting (harvesting row space is between 450mm and 600mm);
5. Stalk kneading and length of cutting-up: ≤150mm;
6. Operational speed:     ≤6km/h;
7. Productivity of net work time: 7—14mu/hour.
8. Rate of complete peeling of corn leaves:    ≥85%
9. Loss rate of kernel: ≤2%
10. Loss rate of cluster: ≤3%
11. Length of cutting-up stalks   ≤100 mm
IV. Cornstalk processing device
According different needs for cornstalk in different area, we have designed two different processing devices for cornstalk, so that the users can choose from two processing device of returning stalk to field and collecting stalk as forage, of which the device collecting stalk as forage has the following three functions:
I. smashing cornstalk and return it to field;
II. Realizing the work of cornstalk collecting, chopping, kneading and blower and loading.
III. Realizing the operation of stalk-smashing and swathing, which can be supplied to bander to be banded
