High manganese steel cast hammer claws, thickened and wear-resistant straw crusher blades
The hammer claw, as a core wear component of agricultural equipment such as straw crushers and stubble removers, directly determines the efficiency and effectiveness of agricultural machinery operations. This particular hammer claw is designed specifically for high-intensity farmland operations. It is precision-cast from high-manganese steel/high-chromium alloy and, through a heat treatment process, significantly improves surface hardness while maintaining core toughness. Its design is intended to handle the crushing of hard straws such as corn, sorghum, and cotton, making it an ideal choice for deep plowing and returning straw to the field in modern mechanized agriculture.
1、Exceptional Wear Resistance: The product is made of high-quality high-manganese steel (Mn13) or high-chromium cast iron, and undergoes water toughening treatment. In actual operation, the surface hardens due to strong impacts, increasing the surface hardness to HRC55-60, while the inner layer retains high toughness. This "hard on the outside, tough on the inside" characteristic allows it to have a service life 2-3 times longer than ordinary cast steel hammer claws, even in harsh soil conditions such as sandy and hilly terrain.
2、Scientific Mechanical Structure: The hammer claws feature a streamlined beak/arc surface design, which not only increases the contact area with the material but also optimizes the center of gravity distribution. The optimized hammer claw angle ensures the generation of powerful centrifugal and shearing forces during high-speed rotation, instantly tearing and pulverizing thick straw while effectively preventing entanglement on the main shaft. Simultaneously, rigorous dynamic balancing testing guarantees smooth operation after multiple sets of hammer claws are installed, reducing main shaft vibration and protecting the gearbox from additional loads.
3、Safety and Convenience: The product undergoes a carburizing and quenching process to strictly control the difference in hardness between the internal and external parts, eliminating the risk of breakage and splashing due to excessive brittleness during operation, thus ensuring the safety of operators and machinery. The hammer claw mounting holes are precision-machined for a precise fit, compatible with mainstream straw returning machines on the market (such as Hebei, Shandong, and imported models), allowing for easy replacement without the need for secondary hole enlargement.
Whether it's tough corn stubble, damp rice straw, or pruned branches from orchards, this hammer claw demonstrates excellent pulverization fineness, effectively promoting straw decomposition and creating a high-quality seedbed for the next planting season.
Choosing a high-quality hammer claw not only reduces operating costs per acre but is also key to ensuring high availability during busy farming seasons. We are committed to using superior craftsmanship to safeguard your harvest.
