Problems solved by technology

[0003] The traditional rotary excavator includes a drill bit, a rotary joint, a rotary drive device and a hoisting device. The hoisting device hoists the drill bit, the rotary joint and the rotary drive device from bottom to top in sequence. When working, the rotary drive device drives the drill bit on the rotary joint. To excavate the strata, however, the structure of various strata is more complex, and some strata have higher hardness, and the down-the-hole drill must be used to generate a pressure of 120MPA and above to crush the soil layer, but driving the down-the-hole drill requires more energy. consumption and a large driving force source, and the down-the-hole drill cannot work in a humid environment, and ordinary drill bits are not up to the task

Embodiment Construction

[0033] Such as figure 1 — Figure 7 As shown, the present invention discloses a rotary digging machine with a vibrating device, including a rotary digging device and a hoisting device 1 for hoisting the rotary digging device. The hoisting device 1 includes a conveyor 11 for transporting the entire device, a bracket 12, The wire wheel 13 on the support 12 and the hoisting wire 14 wound around the wire wheel 13. One end of the hoisting wire 14 is fixed to the drill bit rotation driving mechanism 3, and the other end is matched with the wire retracting device 15 of the conveyor 11. The drill bit 2 and the drill bit rotation drive mechanism 3 are arranged in sequence from bottom to top. A vibration device 4 is arranged between the drill bit rotation drive mechanism 3 and the drill bit 2. The gravity of the drill bit and the vibration force generated by the vibration device 4 accelerate the digging rate of the drill bit to make The drill bit has better digging ability. As the most ...

Abstract

The invention relates to a rotary drilling machine with a vibrator, comprising a rotary drilling device and a lifting device used for lifting the rotary drilling device. The rotary drilling device comprises a drill bit and a drill bit rotation driving mechanism, wherein the drill bit and the drill bit rotation driving mechanism are arranged in order from bottom to top; the vibrator is disposed between the drill bit rotation driving mechanism and the drill bite. According to the scheme, the rotary drilling machine with the vibrator has improved ground-breaking ability of the drill bit.

Description

Technical field [0001] The invention relates to a rotary excavator, in particular to a rotary excavator with a vibration device. Background technique [0002] Rotary drilling machine, also known as rotary drilling rig, is a tool for road traffic and high-rise building construction. Rotary excavator is a comprehensive drilling rig. It can use short auger bits for dry excavation operations, or use rotary drill bits for wet excavation operations with mud wall protection. The rotary excavator can be used with the hammer to drill and break up the hard stratum before digging. If it is matched with an enlarged head drill, the hole can be reamed at the bottom of the hole. The rotary excavator adopts multi-layer telescopic drill pipe, which has less auxiliary time for drilling, low labor intensity, and does not require mud circulation to discharge slag, which saves costs and is pollution-free. It is especially suitable for basic construction of urban construction. [0003] The traditiona...
