In this paper, in the light of the principle of impact drilling work of hydraulic rock drill, the main factors of affecting the rock drill pore forming efficiency are analyzed. This provides the reference for hydraulic rock drill design and optimization of hydraulic rock drill performance parameters

The rotation chuck bushing is one of the important parts of the buffer mechanism in hydraulic rock drill ZYYG170A, and also one of the parts that is frequently damaged during operation. Whether in the buffering process or the resetting process,Tish arttcle chuck bushing is always clamped between the
