Throat chains - a key component of agricultural machinery

Throat chains play an extremely important role in agricultural machinery, especially in combine harvesters. They are responsible for transferring crop material - mainly grain - from the header to the threshing drum, ensuring a smooth harvesting process. The correct selection and maintenance of throat chains directly affects the performance of the machine and the quality of the harvest. In this article we present their characteristics, functions and tips for selection and operation.

What are throat chains?

Throat chains are specialized conveyor components located in the throat of a combine harvester. The throat acts as a conveyor channel through which harvested crop material is sent from the cutting platform (header) to the threshing system of the machine.
These chains work in demanding conditions, where they are exposed to high mechanical loads, dirt and moisture. Therefore, they must be characterized by exceptional durability and abrasion resistance.

Construction and types of throat chains

Throat chains are most often made of high-strength steel, subjected to hardening or galvanizing processes to increase resistance to corrosion and wear. They are characterized by a robust construction and the presence of special attachments and slats that allow efficient movement of material.

Basic types of throat chains:

1. Single link chains - used in less demanding machines and conditions.
2. Double link chains - dedicated to intensive work where there is a higher load.
3. Reinforced chains - with additionally hardened surfaces for greater wear resistance.

Function of throat chains

The main function of throat chains is to transport crop material from the cutting attachment to the interior of the harvester. The operation of the chains is continuous and dynamic, which requires:

• precision of operation - to avoid blockages,
• resistance to loads - the material must be transported without losses,
• resistance to contamination - dust, dust and crop residues are standard working conditions.

How to choose the right throat chain?

Choosing the right throat chain depends on several factors:

1. Machine model - each combine has specific requirements for the type and dimension of the chain.
2. Operating conditions - if the machine works in harsh conditions, it is worth betting on hardened or reinforced chains.
3. Quality of materials - solid steel and appropriate technological processes guarantee longer chain life.
4. Availability of spare parts - it is worth choosing manufacturers that offer quick access to parts compatible with a particular machine model.

Maintenance and operation of throat chains

Regular maintenance of throat chains is the key to their long-term and trouble-free operation. Here are some tips to implement:

• Lubrication - using the right lubricants minimizes friction and delays the wear process.
• Checking chain tension - a chain that is too loose or excessively tight can lead to chain failure.
• Cleaning after operation - removing plant debris and dirt prevents corrosion and link blockage.
• Replacing worn components - regular condition checks allow you to replace damaged links or bars before failure occurs.

Summary

Throat chains are an indispensable part of agricultural machinery, which significantly affects the efficiency of harvesting. Their proper selection, installation and maintenance are key to the proper operation of the combine. It is worth investing in high-quality products that are resistant to harsh working conditions and mechanical wear. This will help ensure the continuous operation of the machine and minimize the risk of downtime during the most important moments of the farming season.
