Introduction

The High Quality Knife Guard is an essential part of the harvester machinery. It is designed to protect the knife when it comes into contact with foreign objects, thus prolonging the lifespan of the knife and ensuring optimal harvesting performance. The Knife Guard fits perfectly into the harvester machinery and is an important component of the harvesting process.

Functionality

The Knife Guard is located at the bottom of the harvester's cutting platform and acts as a barrier between the knife and any foreign objects. It ensures that the knife maintains its sharpness and reduces the risk of damage to the harvester machinery. The Knife Guard works by deflecting any foreign objects that may come into contact with the knife, thus preventing damage to both the knife and the harvester.

Commonly Worn-out Parts

Harvesters have several parts that are prone to wear and tear. These include:

1. Knife/ Cut Parts: including the main cutting blade, guard plate, and cutting blade drive belt
2. Threshing Drum and Concave
3. Sieve and Cleaning Fan Blade
4. Conveyor Chain and Sprocket
5. Rubber Tracks or Tires
6. Hydraulic Components: including hydraulic cylinders, hydraulic hoses, and seals
7. Bearings
8. Filters: including air, fuel, and oil filters

When any of these parts show signs of wear or damage, they should be replaced as soon as possible to ensure optimal harvester performance and prevent further damage to the machinery.

Symptoms and Replacement of Worn-out Parts

1. Poor Harvesting Performance: If there are too many crop residues left after harvesting, or if the grains are not separated cleanly, the threshing drum and concave may be seriously worn and need to be checked and replaced in a timely manner.
2. Decreased Power or Overheating: If the engine has insufficient power, or if the operating temperature is too high, it may be due to a clogged air filter, or a malfunctioning cooling system. In these cases, the air filter core should be replaced or the cooling system should be inspected and repaired.
3. Decreased Harvesting Efficiency: If the cutting platform is running slowly or the material conveying speed has slowed, it may be due to worn-out drive belts, elongated chains, or worn-out gears. In such cases, the corresponding belts, chains, or gears need to be checked and replaced.
4. Difficult Travel or Increased Noise: If the harvester has rubber tracks, loose or visibly cracked tracks need to be replaced. If the harvester has tires, over-worn or punctured tires need to be replaced. If there is abnormal noise while traveling, it may be due to worn or damaged bearings that need to be replaced.
5. Unstable Hydraulic System Operation: If the hoisting or steering is slow or weak, it may be due to problems with the hydraulic pump, cylinder, valve, or seal. In these cases, the corresponding components should be checked and replaced as necessary.
6. Large-scale Oil Leakage: Whether it is engine oil, hydraulic oil, or fuel leakage, it indicates that the seals have failed or other components have been damaged. The leaking components or seals should be found and replaced in a timely manner.
