Abstract

The invention discloses a reverse circulation impactor and system. The reverse circulation impactor comprises a drill rod component and a coring component. The drill rod component and the coring component are integrally formed, and the drill rod component is arranged above the coring component; the coring component comprises a coring impactor; the bottom of the coring impactor cylinder is in a circular ring shape, and multiple positive circulation sub down-the-hole hammers are arranged on the circular ring at intervals; the drill rod component is used for providing a high-pressure air channel for the coring impactor. The device and the system are simple in structure, safe, effective, reliable and easy and convenient to operate, the drilling efficiency of the large-diameter impactor can be effectively improved, and the cost consumed by a drilling tool is reduced.

Description

technical field [0001] The invention relates to the technical field of drilling machinery, in particular to a reverse circulation impactor and its device. Background technique [0002] The down-the-hole drilling rig is a kind of construction engineering equipment for piling holes. It is suitable for drilling blast holes in metallurgy, coal, building materials, stone, railways, hydropower construction, national defense construction, and earthwork. Compared with common rock drills, it has the advantages of drilling It has the characteristics of high drilling efficiency and wide application range, and is the current general rock drilling equipment. [0003] With the development of industries such as metallurgy, coal, building materials, railways, hydropower construction, national defense construction, and earthwork, there is more demand for drilling construction with a diameter of 600mm to 1200mm and above 1200mm. [0004] At present, there are large-diameter impactors on the ...
