由山东省水科所、中国农机院、北京市水科所、山东聊城地区水利局、山东阳谷县水利制修厂共同研制的1G-300型立式挤压水泥土制管机于1981年底通过鉴定。田间排灌工程地下管道化,具有节约能源、节约土地、省水、便于机耕、能提高排灌质量等优点,但是,由于目前管材价格较高,使大面积的应用受到限制。近年来,一些省、市、地区把水泥土用于农田地下排灌工程,取得了较显著的经济效益。1G-3100型立式挤压制管机就是为制内径150～300毫米的水泥土管而研制的。 1G-300型立式挤压水泥土制管机(如图)由大小锥齿轮总成、主轴、压头总成、上压板、管模、底转盘、主机架,提升机构总成、电机和电器控制等部分
The 1G-300 vertical extrusion cement soil pipe making machine co-developed by Shandong Water Institute, China Agricultural Machinery Institute, Beijing Water Science Institute, Liaocheng Regional Water Conservancy Bureau and Shandong Yanggu Water Conservancy Plant was put into operation at the end of 1981 Through the identification. Underground irrigation and drainage projects in the field have the advantages of saving energy, saving land, saving water, facilitating mechanization and improving irrigation and drainage quality. However, due to the high current pipe prices, the application of large area is limited. In recent years, a number of provinces, municipalities and regions have used cement soil for underground irrigation and drainage projects in farmland, and achieved remarkable economic benefits. 1G-3100 vertical extrusion pipe machine is to make the diameter of 150 to 300 mm cement soil pipe developed. 1G-300 vertical extrusion cement soil pipe machine (pictured) by the size of bevel gear assembly, spindle, ram assembly, the pressure plate, the mold, the bottom plate, the main frame, hoisting gear assembly, motor and Electrical control and other parts
