Drilling machine drilling device with dust falling function

Abstract

The invention discloses a drilling machine drilling device with a dust falling function, which comprises a gate-type rack, a hydraulic cylinder, a lifting seat, a spiral drill rod, an automatic water replenishing mechanism, a flushing assembly, a cleaning assembly and a dust falling assembly, the hydraulic cylinder is fixedly mounted at the top end of the gate-type rack, the lifting seat is slidably mounted on the gate-type rack, a motor cover is arranged at the upper end of the lifting seat, a driving motor is arranged in the motor cover, an output shaft of the driving motor is connected with a spiral drill rod, and the spiral drill rod is located below the lifting base. By arranging the dust falling assembly, in the drilling process, a water suction pump can be used for conveying water into a first atomization water pipe through a first water conveying pipe, and water in the first atomization water pipe is divided and conveyed into a second atomization water pipe through a telescopic water conveying pipe; and water is atomized and sprayed out through atomization nozzles on a first atomization water pipe and a second sewage water pipe, the phenomenon that dust flies in the drilling process can be effectively reduced, and the dust falling effect is good.

Description

technical field [0001] The invention relates to the related field of drilling rigs, in particular to a drilling device for a drilling rig with a function of reducing dust. Background technique [0002] Rotary drilling rig is a special construction machine for drilling holes in cast-in-situ piles. It is widely used in municipal construction / highway and railway bridges, high-rise buildings and other foundation constructions. It is suitable for clay, silt sand, silty soil, artificial backfill and soil containing Hole-forming operations in various geology such as some pebbles and gravel formations. [0003] During the construction process of the existing drilling rig, large dust will be generated, which makes the working environment relatively bad and affects the physical and mental health of the workers, and the existing drilling rig is inconvenient to maintain its drill pipe during use, making the drill pipe There is a lot of soil stuck on the top, and it cannot be cleaned up...
