Description

超强型金刚石复合片钻头
技术领域
本发明属于破岩工具，主要用于煤矿瓦斯抽放孔、探水孔、注浆孔以及地质勘探钻孔，具体涉及一种超强型金刚石复合片钻头。
背景技术
现有的钻头耐磨性较低，在实际应用中，金刚石复合片容易崩落，在钻孔过程中缩径现象较明显，从而影响单支钻头钻孔深度。
发明内容
本发明旨在提供一种耐磨性较好、抗冲击韧性较高、缩径现象不明显、使用寿命较长的超强型金刚石复合片钻头。
实现本发明的技术方案是：包括钻杆、钻头，钻头和钻杆通过螺纹连接，其特征是钻头包括金刚石复合片、破岩柱、水孔、保径条，钻头上镶嵌有破岩柱且钎焊有金刚石复合片和保径条。
本发明可以钻入中硬岩层，耐磨性好、抗扭性强，破岩速度较快，冷却排屑好，缩径现象不明显，施工效率高。
附图说明
图1是本发明实施例中钻头结构图。
图2是图1的俯视图。
图3是本发明实施例钻杆的结构图。
图中：1、金刚石复合片；2、破岩柱；3、水孔；4、保径条；5、连接螺纹；6、钻杆。
具体实施方式
实施例：图1、图2、图3所示，本实施例包括钻头、钻杆6，钻杆6通过螺纹和钻头连接，钻头上镶嵌有破岩柱2、钎焊有金刚石复合片1和保径条4，即钻头的端部的等分设有三个刀翼，破岩柱2、金刚石复合片1和保径条4均设置在刀翼上，钻头上设有出水孔3，以保证钻岩过程中的刀翼冷却和及时排屑。
