Do You Know about The Chain of A Rice Harvester?

Rice harvesters are one of the most common agricultural machines in life. In addition to grain combine harvesters, there are also many models specifically used for harvesting rice. The harvesting operations of these machines all rely on the cooperation of cutting knives, chains, sprockets and chain rakes. The cutting knife is responsible for cutting off the plant roots. The chain rake composed of chains and rake rods is responsible for sending the plants into the threshing bin. The sprocket drives the rotation of chains and other components throughout the process.

The chains of rice harvesters are roughly divided into two categories. One type is the plate-attached chain, which is used on grain combine harvesters and is used in combination with rake rods to form a chain rake, responsible for lifting and transporting the entire plant to the threshing bin. The other type is the special pointed tooth chain for Kubota semi-feeding rice harvesters, which transfers plants along the fuselage to realize the stripping of ears and stalks. Both types of chains adopt high-quality raw materials, efficient process equipment and advanced heat treatment. Although the surface treatments are slightly different, the products all have characteristics such as high tensile strength, high fatigue strength and wear resistance.

Pointed tooth chain - Special for Kubota rice harvester.

Plate-attached chain - Forming a chain rake by combining with rake rods.

Six Core Advantages of Rice Harvester Chains

①Chromium plating on the pin shaft - Wear-resistant, high temperature-resistant and corrosion-resistant.

②Powerful pre-tensioning - Improves the fatigue resistance of the chain plates.

③Shot blasting treatment - Extends the service life of the chain and prevents micro-cracks.

④Automatic oiling - Uniform oiling and high efficiency.

⑤Four-corner riveting - Enhances the firmness between the pin shaft and the chain plates.

⑥Seamless sleeve - Not prone to deformation, improving the fit and wear resistance.

Sprocket for rice harvester

It has achieved full coverage of corn harvesters, wheat harvesters, rice harvesters, potato harvesters, balers, green storage harvesters, etc. All materials are made of high-quality No. 45 steel, 40Cr, 20CrMnTi, QT500, QT400, etc. The processing specification range is from 06B to 20B. The surface treatment methods include blackening, galvanizing, phosphating, painting, electrophoresis, etc. The whole process is processed by precision imported machine tools with independent control. Lean production is implemented and strict quality management control is carried out.

Six processing highlights of sprocket for rice harvester:

1.One-time molding by imported lathes, with roughness comparable to precision gears.

2.Forged from high-quality steel, with a service life 15% longer than that of machined products.

3.Optimized design for stable transmission and low noise.

4.High-precision hobbing processing for accurate meshing and not easy to jump off the chain.

5.High-frequency quenching without soft spots to avoid local excessive wear.

6.Three-dimensional surface strengthening treatment to eliminate stress and improve wear resistance.

The chain rake of the rice harvester combines the dual advantages of chains and high-strength rake rods. It runs smoothly without abnormal noise, has reliable performance and a long service life, and can provide greater lifting force for crops.
