犁铧是铧式犁犁体的重要零件。其作用是 ,在犁进行耕作时 ,犁铧沿水平方向将土垡切开 ,并推动垡片沿犁铧与犁壁组成的犁体曲面形成后垡推前垡的趋势 ,将土垡挤压、破碎和翻转 ,并侧向抛进前铧的犁沟里。据测定 ,犁铧的工作阻力约占犁体工作曲面总阻力的５０ %。犁铧的磨损非常 Plowshare is an important part of the plow plowshare. Its function is that when the plow is tilled, the plow -share cuts the soil horizontally along the plowshare and pushes the plowshare along the plowshare and the plow wall to form the surface of the plow body, and then pushes the forehead puddle. The soil plow is crushed and crushed And flipped and thrown laterally into the furrow of the former. It has been determined that the ploughshare’s work resistance is about 50% of the total resistance of the plow body’s work surface. Plowshares wear very
