Diamond drill bit with splayed convergent alternate waterways

Abstract

The invention provides a diamond drill bit with splayed convergent alternate waterways. According to the diamond drill bit, cutting teeth and the splayed convergent alternate waterways are arranged atthe upper end of the head of the diamond drill bit along the circumference, the splayed convergent alternate waterways comprise a plurality of end face water gaps, outer water grooves and inner watergrooves, outer side walls of inner working teeth are concave inwards to form the outer water grooves, inner side walls of outer working teeth are concave inwards to form the inner water grooves, theend face water gaps comprise forward flow water gaps and reverse flow water gaps which are obliquely arranged, adjacent forward flow water gaps and reverse flow water gaps are reversely arranged and distributed in a splayed shape or an inverted splayed shape, the splayed shape and the inverted splayed shape are alternately arranged, outer side ports of the forward flow water gaps and the reverse flow water gaps communicate with the ends of the outer water grooves correspondingly, and inner side ports of the forward flow water gaps and the reverse flow water gaps communicate with the ends of the inner water grooves correspondingly. According to the diamond drill bit, a working mode of the diamond drill bit can be changed, the working efficiency of the diamond drill bit is improved, the service life of the diamond drill bit is prolonged, drill burning accidents are prevented, and jumping and vibration of the diamond drill bit in the working process are avoided.

Description

【Technical field】 [0001] The invention relates to a diamond drill bit with a figure-eight converging and interlacing waterway. 【Background technique】 [0002] Diamond drill bits are one of the important cutting tools for rock drilling in geological drilling. In recent years, with the rise of labor costs and energy (diesel) costs, drilling has continuously increased the requirements for the efficiency of diamond drill bits. However, the drilling speed and life of diamond drill bits are usually contradictory, and the drilling speed of the drill bit depends on the working pressure and rotation speed given to the drill by the drilling machine. The high drilling speed also further increases the working requirements such as cooling of the drill bit. The structure of the drill bit is an important part of meeting the current drilling efficiency requirements. [0003] For example, the Chinese patent application number CN201810966472.0 discloses a diamond drill bit. The cross-tooth ...

AI Technical Summary

Problems solved by technology

Its structural design is not perfect, and there are still problems such as low drill life

The main defects of the prior art include: (1) the working area of ​​the inner and outer cross teeth of the drill bit is greatly reduced, causing rapid wear and tear on the inner and outer sides, and reducing the life of the drill bit; The force increases, causing the bit to jump easily and reducing the life of the bit
