Agricultural machinery accessories, rotary tiller, curved blade customization, various models of rotary tiller blades
Rotary tillage blade is the core operating component of tractor driven rotary tillage machinery, which cuts, crushes, and flips farmland soil through the combination of the rotational motion of the blade shaft and the forward motion of the unit. As one of the most vulnerable components in agricultural cultivation, the design of rotary tillage blades directly affects the energy consumption, soil quality, and land smoothness of the entire machine operation.
According to the working environment and functional requirements, rotary tillage knives are mainly divided into types such as curved knives, chiseled knives, right angle knives, and curved knives. Among them, the curved blade has a curved edge and sliding cutting function, making it less likely to entangle grass and widely used in rice paddies and straw returning operations. The chiseling knife has strong soil penetration ability and is suitable for cultivating vegetable gardens and courtyards with fewer weeds. In recent years, Y-shaped single handle double wing rotary tillers have been designed with Y-shaped fixed left and right wing plates and curved crescent shapes.
They can not only rotate and cut the root stubble down to the bottom layer of the mud, but also have multiple functions such as soil crushing, slurry lifting, and leveling. The structure is simple and the cost is low. In addition, to cope with high stubble plots, the stubble cutting rotary tiller is often equipped with a combination of L-shaped short blades and IT series curved blades to achieve dual axis layered operation.
High quality rotary tillers usually use 65Mn or 60Si2Mn spring steel as raw materials. Its production requires more than ten processes, including cutting, heating, rolling, forming, punching and corner cutting, heat treatment, and shot blasting. Advanced heat treatment technology and wear-resistant alloy treatment technology enable the blade to not only have high hardness and wear resistance, but also maintain a sharper edge as it grinds, thereby reducing tillage resistance and fuel consumption. The service life can reach 2 to 4 times that of ordinary cutting tools
The design of modern rotary tillers is increasingly emphasizing multifunctionality and adaptability. It can not only complete basic soil crushing operations, but also effectively avoid straw entanglement and improve passability by adding anti entanglement devices or optimizing the blade curve (such as R120mm bending radius). The spiral or curved edge of the rotary tiller cuts and throws the soil at high speed, and with the help of the cover and trailer, achieves secondary soil crushing, making the surface flat and the soil fertilizer evenly mixed after tillage.
