Wear-resistant cast steel hammer claws, wood chipper and shredder cutter heads
This product, as a core and easily damaged component of agricultural straw returning machines, corn harvesters, and other equipment, is specially designed for harsh field operating environments. It is a highly efficient tool for crushing various types of crop straw, high stubble, and weeds.
The hammer claw is integrally cast/forged from high-manganese steel or high-quality boron steel. Through multiple heat treatment processes (such as oil quenching or isothermal quenching), it achieves extremely high surface hardness (HRC 48-55) while maintaining excellent impact toughness internally. This "hard on the outside, tough on the inside" characteristic ensures that the hammer claw is wear-resistant and corrosion-resistant, and not prone to breakage or plastic bending when striking straw, soil, or even small stones at high speeds.
The product typically features a conical or axe-shaped head design, coupled with a sharp cutting edge and a well-designed counterweight hole. The tip is overlaid with an ultra-hard, wear-resistant layer, enabling effective piercing, cutting, and crushing of straw. A smooth, curved transition reduces operating resistance, lowers the tractor load, and simultaneously improves the fineness of the crushing and the uniformity of spreading. The hammer claw handle is molded strictly according to original factory standards, ensuring precise assembly with the rotor pin, minimal clearance, and smooth, vibration-free operation.
1、Long lifespan: Compared to ordinary manganese steel, the improved material increases the lifespan by 30%-50%, significantly reducing the frequency of downtime for replacement in the field.
2、High-efficiency crushing: The optimized impact surface generates powerful centrifugal force, easily processing hard straws such as corn, cotton, and wheat. The crushed material is of uniform length, facilitating subsequent deep plowing and composting.
3、Safe and reliable: Each product undergoes dynamic balancing testing, maintaining stability even at high speeds (typically 2000-3000 rpm), effectively protecting the main shaft bearings and gearbox.
It is widely used in straw crushing and returning machines, stubble destroyers, and harvesters of major brands. Whether in dry fields or paddy fields, it demonstrates excellent working results for upright or lodged crop straw.
