Abstract

The invention discloses a rotary excavating cutting pick with long service life. The rotary excavating cutting pick comprises a pick handle, wherein a connecting opening is formed in the bottom end of the pick handle; a limiting structure is arranged at the top end of the pick handle; a bearing is fixedly connected to the upper part of the pick handle; a protecting structure is arranged at the upper part of the pick handle; a durable structure is arranged at the upper part of the pick handle, and comprises a head body; the head body is fixedly connected to the upper part of the bearing; a diamond layer is arranged at the top end of the inner part of the head body; a conical shell is fixedly connected to the upper part of the head body; a pick head is fixedly connected to the top end of the conical shell; and a plurality of layers of diamond are arranged in the diamond layer in a staggered manner. According to the rotary excavating cutting pick with long service life disclosed by the invention, the head body, the diamond layer, the pick head and the conical shell are arranged, so that the service life is prolonged, the cost is reduced, the consumption of the cost is reduced, the rotary excavating cutting pick has certain durability, and the problems that the service life is short, the consumption of the cost is high, and the rotary excavating cutting pick does not have certain durability are solved.

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...
