4YZ-4A (G4) self-propelled corn combine harvester

Features

• The picking roller of corn head adopts the double helix picking roller and adds the shaving knife, which can pull the stem quickly, without entangling and blocking, and improve the harvesting efficiency.

• The Corn head is upgraded to bilateral transmission, and the transmission box is added. The two sides run independently and do not interfere with each other, and the failure rate is low. The corn head transmission system uses a belt drive to improve reliability.

• Equipped with 2.6 cubic meters of Grain tank, reducing the frequency of unloading grain. Unloading grain at a high position makes the unloading operation more convenient, reduces the auxiliary time of unloading grain, and improves the working efficiency of the machine.

• Equipped with Yuchai brand 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 0.5-1 ha/hour.

• The widened wear-resistant rubber plate is used above the stem pulling roller to reduce the impact of corn ears on the picking roller, reduce the loss of grain, the grain crushing rate is less than 1%, the impurities rate is less than 1.5%, and the total loss rate is less than 5%.

• At the same time, the structure of the peeling machine is optimized, which makes the kernel 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 roller corn head to prevent grain loss during high-speed operation. The low-angle corn head used in the machine is supported by a divider, which has a stronger adaptability to the harvest of fallen corn and a lower grain loss rate.

• Roller corn head has 550, 600mm a variety of row spacing to choose from, strong adaptability. At the same time, the picking chain on both sides of the corn head is adjustable, which can be adjusted according to different planting rows, suitable for different corn planting modes.

• The height of the barker press feeder is adjustable, which can be adjusted according to the maturity of the corn, and it can be peeled completely and cleanly with the lowest grain breakage rate. The peeling roller can realize two modes of high and low adjustment and lateral adjustment, which can adapt to different areas of corn husking operation.

• Corn combine harvester can choose four-wheel drive configuration, especially suitable for hills, mountains and other special working conditions of the working environment, stalk return machine position can be adjusted according to the shape of the plot and agronomic requirements.

• 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.

• The stalk returning machine is equipped with automatic lifting function. When the corn combine is moving forward and backward, the stalk returning machine can lift automatically, which makes the operation simple and saves time and labor. The stem returning operation adopts the secondary chopping process of 'pre-chopping + mid-chopping' to ensure that the cutting effect meets the agronomic requirements.

• 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 transmission of the bract crushing mechanism is upgraded from the chain to the belt drive, which has better performance and better crushing effect.

• 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.

• The interior of the cab of the corn combine harvester is luxurious, beautiful in appearance, equipped with the auxiliary seat, the heating and cooling effect of the air conditioner is good, and the maintenance of the air conditioner filter element is more convenient.

• Equipped with large-capacity oil centralized lubrication device, the installation position is reasonable, convenient for oil filling, equipped with butter centralized lubrication device, convenient and efficient daily maintenance.

• Equipped with the latest shift control mechanism, clear gear, reliable shift, comfortable operation.

• It adopts single pump and single motor, and the pump displacement reaches 90l/min, the motor reserve torque is large, and the machine has strong ability to cross the ridge and ditch.

• 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 toothed belt, and anti-flutter wheel is added, which makes the corn head drive reliable and eliminates the hidden danger of skipping and turning.

• 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 control system adopts ECU control system developed according to the working condition of agricultural machinery, equipped with electronic oil pump with intelligent maintenance reminder function.

• 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.

• In addition to the original general functions of the display, the speed indicator, Acreage meter and other functions have also been added. The grain tank full load alarm device and the walking lock device provide another safety barrier for the operation of the machine.
