4YZ-4B self-propelled corn combine

Features

The corn head pull roll is upgraded to a double-helix pick roll with serrated shape and the shaving knife is added to pull the stem quickly, no entanglement, no blockage, and improve the harvesting efficiency.
The Corn head feeding chain adopts a small intercept chain with a intercept length of 30mm, which realizes the orderly feeding of corn stalk by corn machine, which is more efficient and stable, and the harvest efficiency is higher.
Equipped with 2.6 cubic meter grain tank, less times of unloading grain, high position unloading grain makes unloading grain convenient, increases the effective working time, and greatly improves the working efficiency.
Equipped with Yuchai 240, 260, 280 HP high pressure common rail engine, large torque reserve, strong power, reliable and stable performance and low fuel consumption. The operation efficiency of the corn harvester can reach 8-10 mu/hour, which greatly shortens the harvest cycle.
The adjustable picking board is added above the pull stem roller to reduce the loss of corn ear, ensure the integrity of the corn ear, and reduce the loss rate of corn machine operation, the kernel crushing rate is less than 1%, the impurity rate is less than 1.5%, and the total loss rate is less than 5%.
The structure of the peeling machine is optimized, which makes the grain damage smaller, the stripping rate higher, the processing capacity stronger and the reliability higher.
High baffles are added to the left and right sides of the corn head to prevent grain loss during high-speed operation, and the use of low-angle picking table and divider to support the crop has a strong ability to harvest the fallen corn and a low kernel loss rate. The Corn head rubber chain is optimized for metal rubber block structure, which reduces the grain crushing rate and improves the feeding ability.
The Corn head crop-pulling chain group is changed from symmetrical design to high and low design, and the range of grain feeding is completely overlapping, which completely realizes the plate corn head is not fed in line, and eliminates the phenomenon of flat pushing corn stalks at the front end of the corn head. At the same time, the length of the crop-pulling chain on both sides can be adjusted, which is more suitable for the operation of various planting modes.. The plate corn head has two row spacing options of 550 and 570mm to adapt to different areas and different planting patterns.
The height of the barker press feeder is adjustable, which can be adjusted according to the maturity of the corn, and the peeling is cleaner and the kernel breakage rate is lower. The peeling roller can realize the adjustable mode of high and low roller and flat roller, which can adapt to the corn harvesting and peeling in different areas
The position of the front cut crusher can be adjusted to adapt to a variety of different heights of corn harvest.
Optional four-wheel drive device, suitable for hills, mountains and other special working conditions. The grain tank can be equipped with a high one, the height of unloading grain can reach 3.8m, and the grain truck is convenient to load grain.
The guide rod is configured to make the corn ear evenly spread on the peeling roller, without plugging, peeling completely. Compound barker adopts five sets of 20 roller rubber barker, which has high stripping rate and less grain loss. The widened debris discharge structure makes the stalk discharge smooth, and the wind direction controlled by the wind deflector is reasonable, which improves the machine's discharge ability.
Obtained the "utility model" patent compound type husker, corn bract stripping rate is high, less seed loss, widened type impurity structure, stalk impurity channel is widened, wind deflector from rubber plate structure to steel plate structure, wind direction control is more reasonable, impurity removal capacity increased by more than 20%.
The double auger seed cleaning was adopted, the cleaning area was large and the diameter of auger was large, and the seed cleaning was clean. Equipped with three levels of miscellanies, miscellanies unimpeded, high husk stripping rate, clean grain cleaning.
The machine adopts the technology of "pre-chopped + mid-chopped straw" for the second stalk cutting and returning to the field. In addition, another set of fixed knives is added to the chopper to cut the stalk finer, which is more suitable for agronomic requirements.
The width of the stalk returning machine is larger than the width of the harvest, and the left and right positions are adjustable, and the working surface of the stalk returning machine is completely the working surface of the harvester
The crushing drive of the bracts is upgraded from the chain to the belt drive, which has better performance and better crushing effect.
The drive belt of the stalk returning machine is upgraded to double toothed belt to prevent the belt from rolling, stripping and abnormal wear. The diameter of the belt pulley is reduced from Φ235 to Φ210, which improves the rotation speed of the stalk returning machine and optimizes the operation effect. The tension wheel diameter is increased, and the transmission is more reliable.
The video viewing system is configured, the display screen is configured in the cab, and the cameras are configured in two places of the combine, which is convenient to observe the situation of the grain tank and the combine during operation. Rear lights are added on both sides of the machine to facilitate operation, inspection and maintenance.
New luxury cab, beautiful interior decoration, equipped with deputy seats, easy to ride, control, steering, braking, stalk return to the field, unloading grain are hydraulic control, light and reliable.
The air conditioning fan is increased from two groups to three groups, the cooling and heat dissipation effect is good, and the maintenance and replacement of the filter element is convenient.
The capacity of the oil centralized lubrication device is increased, the location is reasonable, it is convenient to fill the oil, and the loading of the grease centralized lubrication device reduces the workload of the operator to maintain the machine.
Single pump single motor, and pump displacement up to 90 displacement, simple and reliable, better escape ability.
With enhanced transmission and enhanced left and right wheel side reducer, the operating speed can reach 15km/h, and the transfer speed can reach 45km/h.
The reinforced rear axle equipped with radial tires provides high driving force and low ground pressure. It can easily cope with the challenges of complex and harsh conditions.
The main drive belt of Corn head is equipped with 3HC4010 joint toothed belt, adding anti-flutter wheel, eliminating the hidden danger of single belt skipping and turning, making the drive of corn head more reliable.
Some belts and bearings are used globally renowned brands, and some bearings are maintenance-free bearings to enhance the reliability of the whole machine and reduce the use and maintenance costs.
The anti-entanglement board of the rubber roller of the peeling machine can solve the problem of entanglement, and can extend the service life of the rubber roller and the bearing, and reduce the maintenance cost.
The engine has a 7.5-litre displacement, and the reserve power and torque are sufficient, so the operation of high power segment is effortless and more fuel efficient. The whole machine is more reliable.
Intelligent electronic oil pump with maintenance reminder function. The control system adopts the ECU control system developed according to the working condition of agricultural machinery, which has strong function and adaptability.
In the cab, you can always know the working condition of the combine harvester, equipped with reverse image and real-time monitoring system for grain tank and stripping machine. optional 360 round view, real-time tracking and monitoring of the running state of the machine. Effectively reduce driver fatigue.
The intelligent terminal system detects the working environment in real time, enabling remote diagnosis and accurate service.
Monitor to add speed meter, Acreage meter functions. grain tank full load alarm is equipped, and unloading parking safety device is added.
