Abstract

The invention provides a drilling tool, comprising a drill bit and a swing mechanism which is used for driving the drill bit to rotate; and the drilling tool also comprises a slag removal mechanism which is arranged in the drill bit and capable of collecting broken slag generated during the drilling of the drill bit. The invention also provides piling machinery comprising the drilling tool. As the slag removal mechanism is arranged on the drill bit, the drilling slag generated during the drilling of the drill bit can be collected, the cutting area of native rock surface is increased, and the drilling efficiency is improved; and at the same time, through a suspension sling and a weight, the drilling requirement of deeper and harder stratums can be met, the damage caused by vibration to the machine can be effectively decreased, and the service life of the machine and the drilling tool can be prolonged.

Description

technical field [0001] The present invention relates to the field of machinery, in particular to a drilling tool, in particular to a drilling tool with a slag removal function, and a piling machine including the slag removal function of the drilling tool. Background technique [0002] With the vigorous construction of infrastructure such as highways and high-speed railways in our country, construction machinery including drilling rigs has been rapidly developed and widely used. However, conventional drilling methods rely on rigid drill pipes to transmit torque and provide pressure. Due to the limited length of drill pipes, the length of drill pipes cannot meet the requirements when drilling deep In some cases, the drilling rig is slow in footage and is in a state of vibration for a long time, which will cause a large loss to the whole drilling rig. And such a conventional coring method has a disadvantage, because during the process of coring and cutting into an annular groo...
