为了满足农田基本建设石方开采机械化的要求,河北承德县农机修造厂和中国农机院研制了YR-22型软轴传动凿岩机,并于1978年11月通过了鉴定.凿岩机主要用于农田基本建设石方开采作业中的钻凿爆破孔,在水利工程、交通筑路等石方施工中也可使用.考虑到农业生产的特点,该机具适于在工作点分散、交通不便、无电源山区和搬迁较多的场地工作.适于在中硬以上岩石钻水平孔和向上或向下的倾斜扎. 该机的主要特点: (1)可以充分利用农村现有的动力.如大于5马力以上的柴油机、手扶拖拉机,或大于3千瓦以上的
In order to meet the requirements of mechanized mining of stone infrastructure for farmland infrastructures, YR-22 type soft shaft driven rock drill was developed by Chengde County Agricultural Machinery Repair Factory and China Agricultural Machinery Institute and passed the appraisal in November 1978. Rock drills are mainly used for farmland infrastructures Drilling and blasting holes in the stone mining operation can also be used in the construction of water conservancy projects, traffic roads, etc. Taking into account the characteristics of agricultural production, the equipment is suitable for dispersing at work points, inconvenient transportation, mountainous areas without power supply and Relocation of more site work.It is suitable for drilling horizontal holes and upward or downward tilt bar above the hard rock.The main features of the aircraft: (1) can take full advantage of existing rural power.If more than 5 horsepower Diesel, walking tractor, or more than 3 kilowatts
