暗管排水是改良盐碱地和涝洼地的有效措施,它能控制地下水位,提高地温,增加土壤的透气性。近年来我国大力推广使用暗管排水新技术,已取得了可喜的成果。由于暗管排水沟深多在2米以下,人工开沟劳动强度大、工效低、质量差。为此,中国农机院、水利水电科研院、丹东518拖拉机配件厂、雁北盐碱区排灌工程指挥部共同研制了1KP-250开沟铺管机,并于1982年11月通过部级新产品鉴定。 1KP-250开沟铺管机由机架,万向传动轴、安全离合器、变速箱、锥齿轮减速箱、工作部件、排土部件、坡降控制机构、铺管机构、驾驶台和运输轮组成(图1)。
Hidden duct drainage is an effective measure to improve the salinity and waterlogging depression, which can control the water table, raise the ground temperature and increase the permeability of the soil. In recent years, our country vigorously promote the use of new technology for underground pipe drainage, has made gratifying achievements. Due to underground pipe drains more than 2 meters deep, labor-intensive manual ditching, low efficiency, poor quality. To this end, China Agricultural Machinery Institute, Institute of Water Conservancy and Hydropower, Dandong 518 tractor parts plant, Yanbei saline saline irrigation and drainage project headquarters jointly developed a 1KP-250 trenching pipelaying machine, and in November 1982 through ministerial new products Identification. 1KP-250 Trenching pipelaying machine consists of machine frame, universal shaft, safety clutch, gearbox, bevel gear reducer, working parts, earthmoving parts, slope control mechanism, pipe laying mechanism, bridge and transport wheel (figure 1).
