Corn maize harvester machine

Corn maize harvester machine is used to harvest corn from fields, and divide it into two types including hand-operated corn cutter or tractor-driven corn cutter. And they bear different capacities and structures, but the harvesting effect is perfect. After harvesting the corn. We can also use the corn thresher to get corn kernels. And if we want to process the corn furtherly. We can also use the corn grinding amchine to process the corn into flour.

Type one

This maize harvester machine developed by our company bears new design, adopting domestic first-class mechanical drive and hydraulic drive technology. And it is easy to control and operate. Also, maize harvester machine integrates the picking, conveying, peeling, packing and straw crushing as a whole, meeting the needs of users in different regions.

The corn harvester machinewith straw returning should cut as far as possible after the corn is ripened for 3 to 5 days. And in this way, the kernel of corn is full and the water content of them is low that is good for peeling the corn husk. In addition, yellow straw with low water content can be effectively crushed, reducing labor time.

Maintenance of several important parts of maize harvesting equipment

1.Engine

The temperature of the muffler on the corn cutter is quite high. So, the user must clean the debris around the engine exhaust pipe according to the situation, and keep the engine, especially the exhaust pipe clean.

2.Main clutch

(1) The operator should always check the working status and performance of the main clutch, and it should be repaired or adjusted in time if there are any impurities on it.

(2) Also, regular lubrication should be carried out.

(3) When disassembling and assembling, you shall be sure to properly assemble the separation bearing and separation bearing cover as required.

(4) It is necessary to ensure the correct position of the rear dynamic pressure plate and fixed pressure plate to prevent the adjustment of the clutch clearance due to the collision between the rear movable claw guide sleeve and the fixed plate separation spring guide pin.

(5) And we should check the complete condition of the clutch connecting pin, the connecting rod and the split pin in time. If the gap between the pin and the hole is too wide, we should replace the split pin in time to prevent accidents.

3.Straw chopping device

(1) Tighting the power fixing bolts of corn cutter.

(2) The movable blades should be replaced in time after wear due to long-term use, but you shall pay attention to the direction of the blades when replacing.

(3) Check the working condition of the moving shaft driving chain in time, and when the chain is lost or deformed. It is necessary to fill the joint or replace the chain in time, ensuring that the sprocket circuit is correct.

4.Steering bridge assembly

Pay attention to the fixing condition of the steering rod to ensure the fixing is reliable.

5.Hydraulic system

(1) Looking over the sealing of hydraulic pipelines. There shall be no oil leakage between joints and valve joints.

(2) The pressure of the reversing valve has been set before delivery, and it is forbidden for the user to blindly increase the pressure to prevent the pipe valve from being broken after being subjected to high pressure.

(3)The same type of hydraulic oil must be used from beginning to end to prevent the chemical reaction caused by the mixed oil.

(4) Hydraulic oil must pass the oil filter to prevent dirt from entering the system, causing damage to the hydraulic components.

(5) Also, hydraulic valves of corn cutter must be carried out by professional maintenance personnel.

Common faults and related solution of corn harvesting machinery

(1) Straw blockage

Reason: The position of the picking board is not suitable (the gap is too close), and the transmission triangle belt is too loose.

Solution: Adjust the clearance of the picking plate to the appropriate size. Due to the different thickness of the straw, the tension of the transmission belt is adjusted between 20-50mm.

(2) The smashed straw is too long

Reason: The clearance of the movable knife is too long, and the blade of it is not sharp.

Solution: Change the clearance between the fixed knife and the movable knife ranging from 0.3-1.5mm.

(3) The peeling effect is not good

Reason: The peeling rubber roller is seriously worn, slipping from the driven rubber roller.

Solution: We should change the pressure of stripping roller by adjusting the bolts or replace the stripping roller.

(4) Common faults in the gearbox

Phenomenon: The gearbox has abnormal noise, oil leakage or overheating.

Reason: Gear or bearing is worn. Installation direction of oil seal is wrong or aging. Side gap is too close and there are little lubricant oil.

Solution: 1. Adjust the gear or bearing installation clearance.

2. Replace damaged parts.
3. Reinstall or replace the oil seal.
4. Tighten the bolts and adjust the oil to the appropriate height.

Type two

It is a small size corn harvesting machine and suitable for individual farmers. The machine is easy to operate in the field, and one person can finish all the processes. What’s more, due to the new design of a small container at the side of the machine, corn can directly fall down it after harvesting. In addition, this cutting corn machine also can crush the corn straw into pieces, increasing the nutrition of the soil.
