Put.
Background technology
Down-the-hole drill is a kind of important construction machinery in mining machinery at present.Down-the-hole drill is in the course of the work
It is a key factor affecting construction that dust is revealed, so down-the-hole drill dust hood is the important portion of dust pelletizing system
Part.There is Railway Project in current domestic dust hood in real work: the life-span is short, well damage, impact grinding
After rock particles, through high pressure draught, with flank speed, from hole, bottom blowing goes out with strength, and successively clash into catch dirt
Cover, is particularly serious during perforate operation；Serious leakage problem, there are vibrations etc. during work can affect and catch dirt
Cover laminating ground, causes there is gap with ground, and dust leaks；And it is designed to not in structure sealing
Enough tight, dust also can be made to leak from hole.
A kind of hidden hole drilling type dust arrester disclosed in the patent No. 201420119741.7, including dust hood body, in institute
The upper end of the dust hood body stated is provided with the dust board surrounding drilling rod, and fairlead is sleeved on drilling rod and is inserted into
In described dust board, the upper end of described fairlead is provided with convex more than the internal diameter of described dust board of diameter
Shoulder, the cylindrical of described fairlead contacts cooperation with the endoporus of described dust board, and described fairlead is with described
Dust board energy relative rotary motion and linear relative movement.Make though this patent plays dedusting to a certain extent
With, but when dust hood is subject to high impact, gap can be there is with ground, dust can be revealed, and can damage simultaneously
Dust hood.
Therefore, for improving dust trapping device service life, reduce dust pollution, improve efficiency of seizing dust, dust hood
Improvement is that those skilled in the art need badly now and solve the technical problem that.
Summary of the invention
The purpose of the present invention is that and overcomes the deficiencies in the prior art, it is provided that a kind of life-span is longer, efficiency of seizing dust
Higher automatic compensation type double-layer seal dust trapping device.
