根据历年的经验,上海地区要小熟高产,必须开好深淘以降低地下水位。为了满足开深沟的要求,金山县廊下人民公社农机厂学习了兄弟县社的经验,几经改革,试制成同手扶拖拉机配套的L×-11型绳索牵引装置及双面出土开淘犁。双面出土开沟犁该犁是为了满足本地开挖沟底10厘米、沟面16厘米、沟深40~45厘米的要求而设计的。它由犁铲、犁壁、犁床、犁柄、犁柱、犁辕、分泥刀、直犁刀及宽度调节器、深度调节板、拉钩前导板等构成(图1)。用该犁在本地土质条件下开沟,当沟深在30厘米以内可一犁开出。沟深40~45厘米要
Based on years of experience, the Shanghai area should be relatively small and high-yielding, and deep-seaming must be done to reduce the water table. In order to meet the requirements of the open ditch, Jinshan County People’s Commune Nongxia Agricultural Machinery Factory brothers learned the experience of brothers and counties, after several reforms, trial-made tractor with walking tractor supporting L × -11 rope traction device and double-sided unearthed open Amoy plow . Double-sided excavated Ditching plow The plow is to meet the requirements of the local excavation ditch 10 cm, ditch 16 cm, ditch depth of 40 to 45 cm. It consists of a plowshare, a plow wall, a plow bed, a plow handle, a plow column, a plowshare, a trowel, a straight coulter and a width adjuster, a depth adjustment plate, a pull hook front guide plate and the like (Figure 1). With the plow ditches under local soil conditions, when the furrow depth of 30 cm can be a plow out. Ditch deep 40 ~ 45 cm to
