Embodiment 1

[0050] Please refer to Figure 1-Figure 7 , the present embodiment provides a drill pipe device 100, which includes:

[0051] Drill barrel body 10, the drill barrel body 10 has an accommodation cavity 11, the bottom of the drill barrel body 10 is provided with an opening communicating with the accommodation cavity 11, and the bottom of the drill barrel body 10 is provided with a positioning member;

[0052] A drill rod 20, one end of the drill rod 20 is connected to the drill barrel body 10, and the other end of the drill rod 20 is provided with a drill bit 21, and the drill bit 21 extends out of the accommodation chamber 11;

[0053] A closure, the closure is rotatably connected to the drill pipe 20, and the closure is provided with a drilling blade;

[0054] The drill pipe device 100 has a drilling state in which the drill pipe body 10 rotates along a first preset direction, the locating member resists and drives the sealing member to open the opening, and the drill pipe bo...

Embodiment 2

[0092] This embodiment also provides a drilling machine, which includes the above-mentioned drill pipe device 100 , which has all the functions of the drill pipe device 100 .

[0093] For the structure of the drill pipe device 100, reference may be made to Embodiment 1.

[0094]In summary, the present invention provides a drill pipe device 100, which can clean the sediment at the bottom of the pile foundation, which is beneficial to reduce the thickness of the sediment at the bottom, improve the primary hole formation rate of the pile foundation, and greatly reduce the economic cost. The structure design is reasonable, the overall use effect is better, and the market application potential is huge.

Abstract

The invention provides a drill barrel device and a drilling machine, and belongs to the technical field of drilling machines. The drill barrel device comprises a drill barrel body, a drill rod and a sealing part. The drill barrel body is provided with a containing cavity, an opening communicated with the containing cavity is formed in the bottom of the drill barrel body, a positioning part is arranged at the bottom of the drill barrel body, one end of the drill rod is connected with the drill barrel body, a drill bit is arranged at the other end of the drill rod, the drill bit stretches out ofthe containing cavity, the sealing part is rotationally connected to the drill rod, and the sealing part is provided with a drilling blade. By means of the drill barrel device, sediment at the bottomof a pile foundation can be cleaned away, the thickness of the sediment at the bottom can be reduced, the one-time pore-forming rate of the pile foundation is increased, and meanwhile the economic cost is greatly reduced. The drill barrel device is reasonable in structural design, good in overall use effect and high in market application potentiality. The drilling machine comprises the drill barrel device and has all the functions of the drill barrel device.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a drill tube device and a drilling rig. Background technique [0002] With the rapid development of the global economy, the continuous expansion of the scope of basic construction, the concept of people-oriented and environmental protection, and the continuous strengthening of the implementation of relevant laws and regulations, the pile foundation, especially the cast-in-place concrete pile foundation, has almost replaced the foundation. a wide range of application space. [0003] Due to its high efficiency, less pollution, and multiple functions, the rotary drilling rig is widely used in the construction of cast-in-place concrete piles at home and abroad to meet the needs of the above-mentioned comprehensive development. [0004] Drilling process of rotary drilling rig Rotary drilling to form a hole is first of all through the drilling rig's own walking function and the ...
