Straw returning is the necessary action for the green development of agriculture, but the problem of "winding+wearing" of straw returning blade makes the agricultural machinery hand ache: corn and rice straw fibers are easy to wind the blade body, resulting in a sharp increase in working resistance and more than 20% increase in energy consumption; At the same time, the sediment and impurities in the straw will quickly wear the cutting edge, and the traditional cutter needs to be stopped to clean the winding and polish the cutting edge for 8 hours of continuous operation, and the effective operation time of a day is less than 6 hours. The traditional solution such as anti-winding plate not only increases the weight of the knife body, but also affects the straw crushing effect.
Dow Laser Cladding Equipment provides an integrated solution of "abrasion resistance+self-lubrication": Ni-based self-lubricating composite powder is selected, and special coating is applied on the surface and cutting edge of the returning-field knife. The surface roughness of the coating is Ra ≤ 0.1 μ m, and the friction coefficient is as low as 0.13, making it difficult for straw fiber to adhere; At the same time, the coating hardness reaches HRC61, which can resist sand abrasion. Sectional cladding process is adopted for the equipment, which focuses on strengthening the tool teeth, tool back and other easy-to-wind parts, while the middle part of the tool body is reserved with appropriate toughness to avoid impact and fracture.
