Description

technical field

[0001] The invention relates to the technical field of rotary digging picks, in particular to a rotary digging pick with long service life. Background technique

[0002] As a comprehensive drilling rig, the rotary excavator has strong mobility and can be quickly transferred. The types of drilling tools are various and light, and can be quickly disassembled and installed. It is suitable for various strata. Recycling slag extraction is required, and it can correspond to various types of ground piles. The current rotary digging picks have a short service life, high cost consumption, and do not have certain durability. They cannot directly impact hard materials such as gravel in the ground. broken, the impact time is longer. Contents of the invention

[0003] The purpose of the present invention is to provide a rotary digging pick with a long service life, so as to solve the problems of short service life, high cost consumption and lack of certain durability i...
