Abstract

本实用新型公开了一种具有防卡孔功能的钻头,它包括钻头本体,其特征在于,钻头本体后部的周面上设有1-3个竖向合金刃,竖向合金刃的刃角朝向与钻头的钻进方向一致。使用时,只要在提钻过程中不停钻,竖向合金刃会继续破碎钻孔中落入的岩石碎块,从而防止钻头卡孔。

Description

具有防卡孔功能的钻头
技术领域
本实用新型涉及***钻眼机具。 
背景技术
在矿山钻眼***时,都是用钻机钻眼,钻机用的钻头有各种形式,但都是在钻头的头端面上设有合金刃,达到冲击或切削岩石的目的。在打竖向的钻孔时,有时发生掉渣现象,即有些岩石碎块落入钻孔中,提钻时很容易卡住钻头,影响施工。 
发明内容
本实用新型的目的是对现有钻头进行改进,设计一种具有防卡孔功能的钻头。 
本实用新型采取的技术方案是,一种具有防卡孔功能的钻头,它包括钻头本体,其特征在于,钻头本体后部的周面上设有1-3个竖向合金刃,竖向合金刃的刃角朝向与钻头的钻进方向一致。 
本实用新型的优点是:使用时,只要在提钻过程中不停钻,竖向合金刃会继续破碎钻孔中落入的岩石碎块,从而防止钻头卡孔。 
附图说明
图1是实施例的主视图; 
图2是实施例的俯视图。 
图中:1-钻头本体,2-竖向合金刃。 
具体实施方式
如图1所示,一种具有防卡孔功能的钻头,它包括钻头本体1,在钻头本体 1后部的周面上设有2-4个均匀布置的竖向合金刃2,图中示出了三个竖向合金刃2,竖向合金刃2的刃角朝向与钻头的钻进方向一致。
