Material of Harvester Blade
High speed steel blades
In certain manufacturing practices, the nature of the work will require the production or packaging line to be in constant use. In these situations, you need a blade that will work continuously without service disruption and one that can also withstand heat.
Tungsten carbide tipped
These blades are very strong and have the capacity to easily handle significant loads. They are sharp, durable and long-lasting, offering precision cuts and reliability. The main body of the blade is made from standard steel, but the edges feature small areas of carbide which have been brazed onto the blade.
Carbide blades
A high-quality carbide blade will retain its edge for between ten and twenty times longer than average tool steel which is a significantly longer period of time, maximising their working life. When it comes to long production runs, these blades would be ideal, particularly where machine downtime would have a detrimental impact on operations.
Stainless steel
This type of blade will resist corrosion which is important for production and packaging. This property is achieved through the addition of chromium.
420
This steel grade will resist stains, but it is quite a soft material, and it won't offer the longevity that you may need. It will lose its edge quite quickly meaning that frequent changes will be required. 420 stainless steel has a higher carbon content, and it's hardness can be increased through heat treatment. This grade of steel is commonly used in the vertical form fill and seal operations or in packaging where blades require regular replacement.
440B
A steel grade made from high carbon stainless steel. It is hardened to a greater degree in comparison with 420 which means that it offers more strength and resistance to everyday use.
440C
This grade of steel is stronger still because of its higher carbon content. It offers a high level of hardness but is slightly less resistant to corrosion than 440B steel grade. It does, however, hold its sharp edge much better and is able to resist stains much more effectively.
How to Maintain Harvester Blade
Clean the cutter regularly
The cutter is one of the core components of the harvester. It should be cleaned and oiled regularly to ensure the sharpness and service life of the cutter.
Replace the cutter regularly
The cutter is a consumable part and should be replaced regularly according to the usage to ensure the quality and efficiency of harvesting.
Check the machine regularly
The harvester is an important agricultural machinery and equipment. The wear degree of each component and the operating condition of the machine should be checked regularly to find and solve problems in time to ensure the normal operation and service life of the machine.
Process of Harvester Blade
Material selection
Common materials for harvester blades include high-speed steel, carbon steel and alloy steel. When selecting materials, the hardness, wear resistance, toughness and other indicators of the blade need to be considered. Generally speaking, high-speed steel harvester blades are more wear-resistant, but the price is higher; carbon steel is relatively cheap but not as wear-resistant as high-speed steel.
Processing
After selecting the right material, the blade needs to be processed. During the processing, various machine tools and equipment, such as drilling machines and lathes, are required to process the blanks into parts with blade shapes. During processing, the size and surface quality need to be strictly controlled to ensure the accuracy and firmness of the blade.
Heat treatment
Heat treatment is an important part of blade production. It can improve the hardness and toughness of the blade and prevent deformation and cracks after long-term use of the blade. Common heat treatment methods include quenching, tempering, carburizing, etc.
Surface treatment
Surface treatment is to protect the surface of the blade and prevent rust and corrosion on the surface of the blade. Common surface treatment methods include metal plating and spraying.
Assembly
After the harvester blade is made, it needs to be assembled. This step requires strict control of the position and angle of the blade to ensure that the contact area between the blade and the mower is maximized.
How to Choose a Harvester Blade
Cutting material
The type of material being cut is a key factor in choosing the right harvester blade. Different materials have different properties, such as hardness, thickness, and abrasiveness, which can affect the type of harvester blade required.
Blade hardness
The hardness of the blade material can affect the durability of the harvester blade. Hard materials, such as carbide or ceramic, are ideal for cutting abrasive materials, while soft materials, such as high-speed steel or tungsten carbide, are better suited for cutting softer materials.
Blade geometry
The blade geometry can affect the precision and accuracy of the cut. There are different types of blade geometries available, such as straight, wavy, and rounded, which are suitable for different applications.
Blade coating
The coating on the blade can affect its wear resistance and lubricity. There are different coatings available, such as diamond, titanium nitride, and chrome, which provide different levels of wear resistance and lubricity.
Machine compatibility
The harvester blade must be compatible with the harvester being used. Different machines have different specifications for blade thickness, diameter, and mounting type, which must be considered.
Cutting speed and volume
The cutting speed and volume required for the application can also affect the choice of harvester blade. For high-speed cutting operations, a harder, more wear-resistant blade material may be required, while for low-volume cutting, a softer blade material may be sufficient.
Supplier reputation
It is important to work with a reputable supplier who can provide guidance and advice on selecting the right harvester blade for your specific needs. Look for a supplier with a track record of providing high-quality products and excellent customer service.
The harvester blade mechanism mainly drives the blade to rotate through the drive device to achieve the purpose of cutting crops. Specifically, the drive device of the harvester outputs a certain amount of power to drive the transmission device to rotate, thereby driving the various components to work together.
As the core component of the harvester blade mechanism, the blade uses its sharp edge to cut the crop into a certain length of straw. Since the blade is in a high-speed rotating state, there are also strict requirements for the material and hardness of the blade. Common blade materials include high-speed steel, cemented carbide, etc.
In order to ensure the life and cutting effect of the blade, the harvester blade mechanism is also equipped with an adjustment device and a protection device. The adjustment device can adjust the cutting depth of the blade, and the protection device can stop the cutting work in time when the blade encounters external obstacles to avoid damage to the blade.
Detailed Steps for Replacing Harvester Blades
Preparation
Replacing the blade requires the preparation of the required tools, usually wrenches, tensioners and other tools. Before replacing the blade, all power supplies of the harvester need to be disconnected and the machine switch turned off to ensure safe operation.
Loosen the old blade
Before replacing the blade, you need to loosen the old blade first. Use a wrench to loosen the nut locked on the blade screw, and use a tensioner to gently pull the blade outward as needed to avoid damaging the harvester main shaft. You also need to pay attention to safety.
Install the new blade
After removing the old blade, you need to install the new blade correctly according to the instructions provided by the harvester manufacturer. First, align the new blade with the main shaft, then tighten the nut with a wrench, and fix the blade with a tensioner. When installing the new blade, be careful not to install it too tight or too loose to avoid affecting the cutting effect.
Adjust the blade position
After replacing the blade, you need to adjust it according to the harvester's instruction manual. Usually, you need to adjust the blade position and height to ensure the best cutting effect. During the adjustment process, you need to pay attention to keeping the cutting smooth and not wearing the blade excessively.
Precautions
