Dalian Corn Harvester Cutting Platform Assembly Fault First Aid Guide: Common Problems and Quick Solutions

During the corn harvest season, any malfunctions may delay farming hours and cause losses. Mastering the first aid methods for common faults can quickly restore the operation of equipment.

1、 Cut table blockage: foreign object entanglement and poor transportation

Blockage of the cutting platform is a common problem, often caused by corn stalks or weeds wrapping around the picking roller or conveyor chain. After discovering the blockage, immediately stop the machine and turn off the engine, clean up the debris wrapped around the picking roller and the feeding chain, check if the chain is loose, and adjust the tension wheel if it is loose. If corn accumulates in the conveyor trough, the drive shaft can be manually rotated to discharge the material. Preventing blockages can be achieved by regularly cleaning the cutting platform and avoiding areas with excessive weeds during operations.

2、 Abnormal ear picking: Grain loss and incomplete ear picking

Improper clearance between the picking rollers can easily lead to grain shedding or incomplete picking. By adjusting the adjustment bolts on both sides of the picking roller, the gap is controlled at 8-12 millimeters (adjusted according to the corn variety). If the picking roller is severely worn, it needs to be replaced with a new roller; Blade passivation can affect the cutting effect of straw, and it should be polished or replaced in a timely manner. In addition, check the height of the ear picking platform to ensure that it maintains a distance of 15-20 centimeters from the ground to avoid being swept into the soil due to being too low.

 

3、 Transmission failure: Chain breakage and belt slippage

Chain breakage or belt slippage can cause power transmission failure. Check if the chain is worn or deformed. If it breaks, replace it with a chain of the same model and readjust the tension; Belt slippage is often caused by looseness or surface oil stains. You can wipe the surface of the belt and adjust the tension wheel. If the belt ages, it needs to be replaced. In daily maintenance, regularly apply lubricating grease to the chain to reduce wear and tear.

4、 Hydraulic system malfunction: abnormal lifting and lowering

The slow or unable lifting of the cutting table of the Dalian corn harvester may be due to insufficient hydraulic oil, pipeline leakage, or hydraulic pump failure. Check the oil level in the tank first, and add hydraulic oil that meets the specifications if it is insufficient; If there is oil leakage at the pipeline joint, tighten the joint or replace the sealing ring; If the hydraulic pump has no pressure output, it is necessary to contact professional personnel for maintenance.

When encountering a fault in the header assembly, following the principle of "shutdown inspection - locating the problem - targeted treatment", most common faults can be quickly resolved. If complex mechanical or hydraulic systems are involved, it is recommended to contact after-sales personnel to avoid further damage.
