Introduction to Agricultural Chain

Agricultural chain refers to chains used in agriculture. It is an essential spare part of agricultural machinery, such as seeders, combine harvesters, rotavators, spreaders, crop sprayers, balers and others. This durable chain can keep machines running efficiently and reduce operations costs.

Types of Agricultural Chain

Agricultural Roller Chain
Agricultural roller chains come in a variety of designs and materials. Some models are plain, while others have slats, pushers, and other attachments. Despite their commonality, these chains provide superior strength, increased durability, and reduced wear. These products are used in the production of fertilizers, pesticides, and other agricultural products. There are many types of agricultural roller chains.

A-Type Agricultural Roller Chain
A-Type chains are widely used in agriculture and livestock production. A-Type agricultural roller chains are made from high-quality steel and feature two setscrews. They have the same characteristics as A-Type chains but are more affordable. A-Type agricultural roller chains are used in applications where clearance is low. Compared to their non-steel counterparts, A-Type agricultural roller chains have heat-treated rollers and side-plates. A-Type agricultural roller chains are ideal for a wide range of farming applications.

MR-Type Agricultural Roller Chain
An MR-Type agricultural roller chain is a steel version of a malleable iron chain. It was originally designed to replace malleable chains with a steel equivalent to ensure smoother operation and increased tensile strength. Typically, these chains are applied in round balers, feed wagon lifts, and combine harvesters. They are also used for material handling.

CA-Type Agricultural Roller Chain
CA-Type Agricultural Roller Chain is one of the most common types of ag-chain. Its open-barrel design makes it ideal for applications where a chain has narrow clearance. This type of agricultural roller chain is usually fitted with two setscrews for easy fitting. In addition, CA-type chains are more resistant to rust than A-type chains.

Cast H-Type Mill Chain
Cast H-Type Mill Chain is an industrial-grade, high-strength steel chain with precision-cored pinholes. Its welded or riveted design allows it to operate on sprockets that are interchangeable with WH78 welded steel chains. Its design allows for a wide range of pitch and diameter, ranging from 2.308 to 4.000 inches.

Steel Pintle Chain
A steel pintle chain is an agricultural device used for conveying and power transmission. Its open barrels help prevent material buildup and seizure. These chains are ideal for agricultural applications because they feature heat-treated, riveted pins that are designed to withstand the toughest working environments.

Press Steel Chain
Press Steel Chain is a versatile chain designed for agriculture. It is commonly used in hay bale elevators, manure spreaders, and live bottom trailers. Because of its dependability and affordability, it has been adopted by many other industries.

Detachable Chain
Detachable chains are a type of industrial belt used in a variety of industrial applications. They are primarily made of steel and can be easily disassembled and repaired while in use. They are typically used in farm equipment such as hay bale elevators and manure spreaders.

Advantages of Agricultural Chain

Increased Wear and Tear
Due to their design, roller chains have fewer contact points between the chain and sprocket teeth compared to link chains. This translates to less friction, minimising wear and tear on both the chain and sprockets. In high-usage livestock machinery, this translates to longer chain life and less frequent maintenance needs.
Because roller chains are built with precision-engineered components like rollers and bushings, this design ensures smoother operation and superior resistance to wear. This enhanced durability makes them ideal for demanding applications in agricultural machinery, where reliability and longevity are essential.

Strength To Handle Heavy-Duty Tasks
Agricultural roller chains typically possess higher tensile strength compared to link chains of similar size and configuration. This increased strength allows them to withstand higher loads of bales or silage and operating stresses encountered in heavy-duty livestock machinery.

Better Performance In Harsh Farming Conditions
Moisture, dust, and contaminants pose constant threats to the gear. Roller chains are designed to mitigate these challenges. Internal lubrication channels ensure even distribution of lubricant, maximising performance even in these harsh environments. This translates to smooth operation and minimises downtime for your agricultural equipment.

Smoother Power Transfer
Efficient power transmission is crucial in agricultural machinery, where consistent operation is essential. Roller chains, with their smooth engagement with sprockets, offer a clear advantage over link chains. This translates to optimised torque, less constraints on gear such as the hydraulic motor and improved performance.

Precision For Reliable Operation
Agricultural roller chain design provide smoother engagement with sprockets and accurate alignment between the chain and sprockets compared to link chains. This minimises the chances of the chain jumping off, especially during sudden changes in load or direction and reduces the risk of derailing even under demanding conditions. Consistent tension distribution, thanks to the rollers and bushings, further reduces the risk of derailing caused by uneven tension. All this translates to reliable operation and peace of mind for the operator.

Application of Agricultural Chain

Farming Machinery
In farming machinery, agricultural roller chains are an important component that is deployed to attain high yielded productivity. It is used to transmit the power within the machinery from the engine or motor to the different components such as wheels, cutting blades, conveyors, and the moving parts of the machine. The prime machinery in which roller chains are used are: Tractor, Combines, Harvester, Baler, Sprayer.

Grain Handling
As with other machinery that uses agricultural roller chains, grain handling also works efficiently with the aid of roller chains. They advance the required power transmission to move grains from one location to another. The effective procedure ensures effective grain processing and storage. In grain handling, roller chains are mostly used in the following ways: Grain Augers, Bucket Elevators, Grains Conveyors.

Conveyor System
The best quality agricultural chains supplied by the roller chain supplier are extensively used in agriculture conveyor systems. These conveyors are designed to enhance the bulk transportation of heavy and bulky materials such as grains, seeds, fertilisers, hay stacks, etc. The effectiveness of roller chains makes them more efficient and ideal for conveying applications.

Irrigation System
Agricultural roller chains play a very important role in the irrigation system. They are especially used in the pivot and lateral move systems. They are functional with the capacity to produce the movement and rotation of the irrigation equipment. The effective and systematic rotation of the equipment ensures the equal distribution of water across the field. Additionally, the roller chains are the most durable and reliable, even with the prospect of challenging environmental conditions.

Sprayers and Spreaders
To protect the harvest from various kinds of pests or insects, it is very important to go for the application of fertilisers, herbicides, pesticides, etc. The agricultural roller chain suppliers ensure that the sprayers and spreaders, which utilise the best application of the roller chains, enhance the equal and adequate distribution of these substances. The proper distribution of the protective element ensures the healthy and high-yielding productivity of the crops.

Handling & Installation of Agricultural Chain

Agricultural Chains for Special Harvesters

Adjusting Chain Length (Number of links)

To shorten a chain to an appropriate length, use a proper jig and employ a method appropriate to the structure of a chain.
It is recommended to use the exclusive jigs.
To shorten a riveted chain, grind away riveted ends of a part
of rivets in the same line (on the same side).
Place a punch at ground end of a rivet and strike a punch with a hammer.
Be careful to hit two pins alternatively.
If pin is withdrawn without grinding off riveted end, a chain will be damaged. Grind away riveted ends.
After withdrawing pins, check to see if bushings are set correctly. If bushings are protruded, smooth power transmission cannot be achieved or strength of a chain is reduced.
Do not reuse the removed parts.

Connection (Installation to Equipment)

Confirm that sprocket shafts are parallel and level and misalignment of sprockets is within tolerance.
Insert a connecting link between both ends (inner ilinks) of a chain. In this case, this connector can be easily made when a chain is engaged with sprockets.
When inserting a connecting link it is important that split pin hole or clip groove is exposed over a connecting link.
Install a split pin or clip.

Proper Slack

Proper slack “S” is determined by the following equation. Adjust shaft-to-shaft distance to set proper slack “S”.
S = 0.02L.
Where, L is span.
In the following cases, determine slack “S” by the equation of S≦0.01L.
Vertical arrangement.
Upper side of chain is slackened.
Shaft-to-shaft distance exceeds 50 times pitch.
Vibration or impact is present.　
Chain starts and stops frequently.
Forward/reverse movements are repeated frequently.
Speed change ratio exceeds 7:1.

Maintenance of Agricultural Chain

Sprocket Alignment and Roller Chain Longevity
The longevity and optimal functionality of agricultural chains are heavily influenced by several factors, one of the most critical being proper sprocket alignment. Sprockets, the toothed wheels that engage with the chain, play a crucial role in transmitting rotational motion from one part of a machine to another. The alignment of these sprockets has a significant impact on the operational lifespan and efficiency of the roller chain.

Ensuring Proper Sprocket Alignment
Ensuring proper sprocket alignment involves regularly checking and adjusting the position of the sprockets as part of your maintenance routine. Specialized tools and techniques, such as laser alignment tools or straight edges, can be used to assess and correct alignment issues.
Meticulous attention to sprocket alignment during both installation and maintenance phases can significantly improve the longevity and operational efficiency of roller chains. By investing in proper sprocket alignment, businesses can achieve greater equipment lifespan, reduced maintenance costs, and improved overall operational productivity.

Maintaining your Roller Chains properly
Maintenance of agricultural chains constitutes a strategic pillar in ensuring the longevity and operational efficiency of machinery. Conducting regular inspections can help preemptively identify and address issues, thereby minimizing the potential for significant mechanical failures.
Adopting routine cleaning and lubrication practices is also key to maximizing the life and performance of roller chains. In terms of adjustments and replacements, a meticulous approach is indispensable.

If you’re going to be hauling around heavy materials like hay bales or logs, it’s important that you find a chain that can handle the extra weight without breaking down or wearing it out prematurely.
Another important factor is how well your equipment will handle wet conditions. If you’re going to be working in rain or snow, you want a chain that can take on water and keep working without failing under pressure.

Q: How to conduct an inspection of agricultural chains?

A: When inspecting the agricultural chains, here are things you need to check and look for:
Are the chains and sprockets adequately attached?
Are the T pins and other components correctly fastened at chain joints? (Take note of the degree of pin bending.)
Is the chain take-up tension correct? )
Are there any foreign bodies impeding the chain's motion?
Is the chain sufficiently lubricated?
Is there any unusual sound produced by the chain when it travels (vibration, noise, etc.)?
Is there any unusual vibration or sound?
Is the chain noticeably rusted, filthy, or otherwise degraded?
Are the chains and sprockets well-aligned?
Are the chain flexing and the rollers moving smoothly?
Is there any chain wear extension?
Is there any unusually uneven wear at the contact locations between the chains and sprockets (inside faces of inner plates, sprocket sides)?
Is chain tension necessary?

Q: How to measure the size of agricultural chain?

A: Measuring the size of an agricultural chain requires a simple tool such as a set of calipers. These measuring instruments are incredibly intricate and can measure the smallest details on your chain. The key measurements that you need to grab are the pitch (P), side plate height (H) and thickness (T), pin diameter (E), roller diameter (D), inner width (b1) and the roller diameter (d1). Each of these measures works together to determine exactly the chain that you will need for your project.
Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line. Instead of measuring a single chain link, measure several from various places along the chain to ensure that you're getting a good average readout of the pitch.
Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you're seeing a good average size.
The pin diameter is especially important for chains that you suspect may be non-standard, but it is a useful measurement all the same.
Even roller-less chains technically have a roller diameter, as you can measure the diameter of the bushing instead of the diameter of the roller.
Measuring the total width of the roller provides a very important measurement, helping get you to the correct product line more quickly.
Finally, find the overall chain width and record it, taking special care to measure only the full width of the master link.

Q: What are most common types of agricultural chains?

A: The most commons agricultural chains are agricultural roller chains, gripping chains, combine chains, rice harvester chains, and steep pintle chains. These chains are of low cost, good wearing and impact resistance and are durable transmission chains for high strength, frequently-used agricultural applications.

Q: What are the features of rice harvester chains?

A: Rice harvester chains are typically made of high-quality steel or alloy materials that are resistant to wear, corrosion, and breakage. They are designed to withstand the harsh conditions of rice fields, including exposure to mud, water, and debris.
The chains consist of a series of interconnected links with sharp blades or teeth attached to them. These blades are strategically positioned to cut through the rice plants as the chain moves through the field. The chain's design ensures that the blades are able to cut the plants cleanly and efficiently without damaging the rice grains.
The size and configuration of the chains may vary depending on the specific type and model of the rice harvesting machine. Different machines require different chain designs to suit their cutting and harvesting mechanisms.
