S-type spring toothed tiller accessories agricultural rake teeth
The S-type spring (commonly known as S-tooth or S-plow leg) is a core working component in modern tillage machinery, mainly used in tillage machines, rotary tillers, and seedbed finishing equipment, playing a role in elastic loosening of soil, soil crushing and leveling, and weed control operations.
This product adopts a unique "S" - shaped curve structure design, usually forged or precision stamped from high-quality high elastic limit materials such as 60Si2Mn (silicon manganese spring steel), 65Mn (high manganese spring steel), or European boron steel. Its manufacturing process is rigorous and requires a fully automatic stick type heating furnace for heat treatment. The hardness of the finished product is usually controlled between HRC 38-48, which has excellent fatigue resistance while maintaining high strength.
Its core working principle lies in "elastic yielding": during operation, the S spring teeth penetrate deep into the soil, and when encountering rocks or hard obstacles, its S-shaped curved part can produce elastic deformation, automatically avoiding backward or lateral collision, effectively preventing damage to the tooth tips or machinery caused by rigid collision; After passing through the obstacle, the material's high elasticity will automatically reset and continue the operation. This design not only protects the entire machine, but also greatly reduces the operational risks in gravel areas.
In terms of functional applications, S-springs are not only used to deeply loosen the bottom soil, break the plow bottom layer, improve soil permeability and air permeability, but also to efficiently crush soil blocks, clean weeds and shallow root vegetation, creating a flat and fine seedbed for sowing. At the same time, it is also suitable for diversified agricultural needs such as throwing and fertilizing, ridge and bed construction, etc.
The surface of the product is usually treated with spray painting, powder coating, or galvanizing to enhance its corrosion resistance in damp soil environments. Its specifications are diverse, with common models such as 32 * 10mm, and can be customized by OEM according to different tractor horsepower and agricultural depth
This accessory is widely used in tractors, rotary tillers, and multifunctional management machines, and is an indispensable consumable accessory in modern agricultural conservation tillage systems
