4YZJ-4A(G4) Stem and ear corn combine

Overview

Features

• The composite corn head with the structure of upper and lower layers is adopted, and the ear picking and straw harvesting are completed at the same time. The harvesting height of the corn head with the upper and lower layers can be adjusted independently according to the different heights of the crops. Stalk collection and cutting effect is good, suitable for cattle and sheep feed.

• The feeding inlet adopts the intensive plucking chain, and at the same time, it is equipped with one long and one short stem roller to improve the feeding effect and the harvesting 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 machine is equipped with an efficient flat peeling machine. The all-rubber roller is not only wear-resistant, but also has high peeling efficiency and clean peeling. The grain cleaning device is designed by double auger and equipped with grain fan. The grain loss is small and the grain cleanliness is high.

• The adjustable picking board is added above the stem roller to reduce the grain loss of corn ears, ensure the integrity of corn ears, and reduce the loss rate of corn machine operation, 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%.

• With the new structure of all-rubber wheel and all-resin peeling roller, the peeling efficiency is high and the seed loss rate is low.The peeling machine adopts five extended peeling rolls, the peeling effect is good, the stripping rate is greater than 95%, the kernel loss is less than 2%.

• Equipped with a front-mounted straw cutting and recovery device that can control the free rotation adjustment, the straw can be crushed and recovered after picking. Equipped with a medium stubble removal and straw returning machine, the stubble and straw are evenly scattered after crushing, and the range of adaptation is wide.

• The 24 cutting knives are arranged in double-row herrine shape, with small cutting Angle, good breaking effect and strong throwing ability. The fixed tool can be replaced and the position can be adjusted to meet the needs of adjusting the clearance of the moving fixed tool in the harvest operation.

• Equipped with an acceleration mechanism after straw shredding, the 8 throwing blades are arranged in double rows in chevron shape, which has better throwing effect and higher efficiency.

• High strength, large swing Angle, closed sprinkling mechanism, long throwing distance, high material concentration, can achieve the left 90°+2° to the right 90°+2° harvest operation, grass sprinkling cylinder can achieve a wide range of height adjustment, to meet the different transport trailer feeding.

• The low Angle design of the Corn head allows it to harvest dwarf corn up to 350mm in ear height, especially in plots where corn is lying down.

• Thanks to the structural design of the rear axle and chassis, the turning radius of the whole machine is only 7m, and it is more flexible when working in small plots.

• The power access can be independently accessed respectively, and the corn head feeding and shredding throwing can be independently accessed successively. When the power is connected, the cutting and throwing part is connected separately first, which is conducive to the discharge of the residual forage and reduces the frustration and impact feeling during the power is connected.

• Optimize the design of the shift control mechanism, make the gear clear, improve the reliability of the shift and control comfort.The control, steering, braking, stalk returning and grain unloading are all hydraulic control, which is light and flexible.

• The returning machine is equipped with automatic lifting function, and the stalk returning machine in the middle of the corn combine harvester automatically lifts when the machine moves forward or backward, which simplifies the operation. The shredder adds a set of fixed knives for better shredding effect.

• The width of the returning machine is greater than the width of the harvest, and the left and right positions can be adjusted. The operation of the returning machine covers the whole working surface of the harvester, and the stubble removal operation is not missed.

• The straw feeding part of the corn head and the joint of the cutter roller can be disassembled, which greatly saves the maintenance time;

• Optimize the design of belt tensioning wheel of returning machine to enhance the stability of belt. The stalk returning machine can also be equipped with a lengthening blade, and the rotating diameter can be 520mm, so the operation effect is better.

• The structure design of the active variable speed wheel, passive variable speed wheel and torque booster is reasonable, the adjustment speed ratio is accurate and reliable, and can withstand large torque.

• The corn ear elevator on the corn head adopts the structure of four parallel chains, each chain has its own independent drive sprocket, and the operation is reliable.

• The clutch adopts a sealed structure design, and the sealing rubber ring is added outside to prevent dust from entering the clutch inside and causing damage during operation.

• 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 material and structure design of the stalk feeding auger, auger retractable teeth and bearing seats at both ends of the Corn head are reasonable, and the strength and stiffness can cope with various harsh working conditions. In addition, the overload protection device is also equipped on the auger

• 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.

• Intelligent electronic oil pump, with intelligent maintenance reminder function, convenient for users to do timely maintenance of the machine.

• The control system adopts ECU control system.All harvesting operations are integrated into one joy-stick for easy operation. The core hydraulic electric control parts are of world-renowned brands.

• Deluxe cab, equipped with suspension seat, advanced center console, soundproof, dust proof, large space, wide view. Equipped with a visual system, a display screen is added in the driver's room, and cameras are configured in two parts of the car body, which is convenient for observing the grain tank and the rear environment during operation.

• 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.
