Abstract

一种钻机碎石钻头，包括上部的潜水砂石泵，潜水砂石泵的上端连有钻杆，其下部设有左右两根吸浆钢管，吸浆钢管下端设有吸口，其潜水砂石泵出浆管上端与钻杆相连；潜水砂石泵的下端连有潜水电机，潜水电机下端连有偏心的破碎锥体，锥体下端连有钻头部件，其钻头部件为一字或十字形，其下设有合金刀头；破碎锥体外围设有壳体，壳体上端固定在潜水电机上，壳体的内表面与破碎锥体的外表面均设有螺旋突起，破碎锥体为上粗下细的圆锥体，壳体为上细下粗的中空圆锥体；进水管穿过潜水电机与破碎锥体的中间，其下端设有喷水嘴，上端连有进水软管。本发明是成孔钻机的专用钻头。

Description

碎石钻头
技术领域
本发明涉及一种钻机钻头，特别涉及一种能破碎卵石的钻机碎石钻头。
背景技术
目前，普通钻机在大块卵石中掘进速度很慢或者不能掘进。
发明内容
本发明弥补了以上钻机的缺点，提供了一种能破碎卵石的钻机碎石钻头。
本发明是通过如下技术方案实现的：
一种钻机碎石钻头，包括上部的潜水砂石泵，潜水砂石泵的上端连有钻杆，其下部设有左右两根吸浆钢管，吸浆钢管下端设有吸口，其潜水砂石泵出浆管上端与钻杆相连；潜水砂石泵的下端连有潜水电机，潜水电机下端连有偏心的破碎锥体，锥体下端连有钻头部件，其钻头部件为一字或十字形，其下设有合金刀头；破碎锥体外围设有壳体，壳体上端固定在潜水电机上，壳体的内表面与破碎锥体的外表面均设有螺旋突起，破碎锥体为上粗下细的圆锥体，壳体为上细下粗的中空圆锥体；进水管穿过潜水电机与破碎锥体的中间，其下端设有喷水嘴，上端连有进水软管。
本发明具有以下的特点：
1、此碎石钻头由于能破碎大块卵石，破碎后的卵石由潜水砂石泵抽取置换，所以能在卵石层中掘进。
2、本碎石钻头采用正循环进水，反循环潜水砂石泵抽取成孔泥渣，成孔效率很高。
附图说明
下面结合附图对本发明作进一步的说明。
附图为本发明的结构示意图。
图中：1、钻杆，2、出浆管，3、潜水砂石泵，4、进水软管，5、吸浆钢管，6、潜水电机，7、进水管，8、壳体，9、孔壁，10、破碎锥体，11、螺旋突起，12、钻头部件，13、喷水嘴。
具体实施方式
附图为本发明的一种具体实施例，该实施例包括上部的潜水砂石泵3，潜水砂石泵的上端连有钻杆1，其下部设有左右两根吸浆钢管5，吸浆钢管下端设有吸口，其潜水砂石泵出浆管2上端与钻杆相连；潜水砂石泵的下端连有潜水电机6，潜水电机下端连有偏心的破碎锥体10，锥体下端连有钻头部件12，其钻头部件为一字或十字形，其下设有合金刀头；破碎锥体外围设有壳体8，壳体上端固定在潜水电机上，壳体的内表面与破碎锥体的外表面均设有螺旋突起11，破碎锥体为上粗下细的圆锥体，壳体为上细下粗的中空圆锥体；进水管7穿过潜水电机与破碎锥体的中间，其下端设有喷水嘴13，上端连有进水软管4。
本发明工作时潜水电机驱动破碎锥体做偏心运动，将进入破碎锥体与壳体之间的卵石挤碎，同时，潜水电机亦驱动下面的钻头旋转掘进，进水管进入的高压射水由喷水嘴喷出，与旋转钻头共同切割地层，泥渣由潜水砂石泵抽取置换。
本发明是成孔钻机的专用钻头。
