Hongyuan series impact drilling rig is a new type of impact drilling rig improved on the basis of the original CZ-22-30 steel rope impact drilling rig. It is mainly used for drilling foundation piles for water conservancy projects, construction projects, roads and bridges, etc. It can also be used for hydrogeological exploration and water well drilling. This machine has good effect on drilling sand layer, clay layer and pebble bedrock. The main features after improvement:

(1) The main drive shaft is changed to half-shaft structure and connected by centering buffer type coupling, which greatly increases the strength and makes the installation and maintenance easier.

(2) The impact mechanism and related parts are strengthened, which is more suitable for the construction requirements of large hole diameter filling.
