结构犁的整机由犁架、犁体、曲拐轴调节机构以及附件(限深轮、支承板或限深滑板)等构成(图4)。犁架总成由犁架、左右支板、牵引板、斜撑杆和曲拐轴等构成(图5)。本系列采用了矩形管梯形焊合平面犁架,通过脆漆法试验、电测和强度计算,结合生产实践所取得的大量依据,证明这种犁架是理想的。本系列共有七种犁架,基本上可满足目前20～80马力级拖拉机配套的要求,每种犁架的主梁上均可安装单铧耕幅为20
Structural Plow machine consists of plow frame, plow body, crankshaft adjustment mechanism and accessories (limited depth wheel, bearing plate or limited depth skateboard) and so on (Figure 4). Plow frame assembly by the plow frame, left and right strut, traction plate, diagonal strut and crankshaft and other components (Figure 5). This series uses a rectangular tube trapezoidal welding plane plow frame, through the brittle paint test, electrical measurement and strength calculation, combined with ample production practice has been proved that this plow is ideal. This series has a total of seven kinds of plow frame, basically to meet the current 20 ~ 80 horsepower tractor matching requirements, each plow frame can be installed on the main beam single-cropped 20%
