Description
Technical Field
The invention relates to the technical field of slag discharge of a down-the-hole hammer, in particular to a slag discharge device of a pneumatic down-the-hole hammer, and belongs to the technical field of slag discharge of the pneumatic down-the-hole hammer.
Background
In order to improve bearing capacity and natural disaster resistance of projects such as railways, highways, bridges and the like, foundation pile embedment is required
The construction is carried out by adopting a down-the-hole hammer below the fresh foundation rock surface, and other building projects also need to adopt a pneumatic down-the-hole hammer to pre-drill pile holes in the construction process of foundation piles.
The pneumatic down-the-hole hammer is a down-the-hole hammer taking compressed air as power, the impact work and impact frequency generated by the down-the-hole hammer can be directly transmitted to a drill bit, then the drill bit and a drill rod are driven to rotate to form the capability of pulse crushing the rock, and meanwhile, the compressed air discharged by an impactor is used for cooling the drill bit and discharging the crushed rock particles out of the hole, so that the purpose of hole bottom impact rotary drilling is achieved.
During drilling of the pneumatic down-the-hole hammer, positive and negative circulation of gas lift and a spiral drill rod are used for combined deslagging, specifically, a spiral blade is adopted to rotate to carry residual soil, air flow of an air compressor blows the residual soil to the spiral blade at the lower part through an impactor, and the residual soil rises along with rotation of the spiral blade to carry the residual soil out of a hole, so that deslagging is realized. Therefore, the slag discharge capacity completely depends on the air flow of the air compressor, and a larger air compressor must be configured to enhance the slag discharge capacity, so that the power consumption is larger, and the drilling cost is higher.
In addition, the drill hole directly discharges slag, more dust flies, the working environment is poor, and the health of operators and the service life of equipment are affected. In addition, the spiral blades are used for discharging slag, the spiral drill rod is continuously lengthened along with the increase of the drilling depth, higher requirements are provided for a drilling machine, and the drilling cost is higher. In summary, how to reduce the power consumption required by slag discharge to reduce the drilling cost is a problem to be solved by those skilled in the art, and therefore, the north-kingdom nanche-vehicle-generation locomotive machinery limited company discloses an invention patent with patent application number 2014100749477 and publication number CN 103790513B (publication date 2016.02.24), which has certain effects in reducing the power consumption required by slag discharge and reducing the drilling cost, but because compressed air flows in an open manner in the space between the drilling wall and the outer wall of the slag discharge barrel, and a large amount of compressed air is consumed in vain, the defect that the compressed air is wasted and the power consumption is large still exists, besides, a part of slag soil is blown into the working space directly from the space between the drilling wall and the outer wall of the slag discharge barrel by compressed air, much dust is still blown, the working environment is poor, the health of operators and the service life of the equipment are affected.
