Background technology
Drilling cuttings method is one of most economical effective method of predicting rock burst on colliery, according to the coal of different drilling depths
Dynamic phenomenon evaluates the stress state in coal and rock, and then the danger of burst of supervision and inspection coal body in powder amount and boring procedure
Property.For the coal body of certain condition, under normal stress effect, the stress state of the coal body of different drilling depths be it is different,
When the stress concentration degree increase in coal seam or stress state exception, the coal dust amount of drilling and the granular size of coal dust will change
Become, so the key for just becoming drilling cuttings method predicting rock burst is collected in the screening of coal dust.But at the scene in work progress, because
Limiting for equipment is influenceed and is collected by dash, it is impossible to screening collection accurately is carried out to the granular size of coal dust, from
And influence the Accurate Prediction of bump.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of collection device of coal dust automatic screening, can keep away
Exempt from dash to dispel coal dust, be easy to coal dust screening to weigh again, it is ensured that the accuracy of Prediction of Rock Burst.
The utility model is that technical scheme is used by solving above-mentioned technical problem：This coal dust screens collection device, bag
Include protective cover, top handle, semi-cylindrical hole sealing tube, mozzle, arc sieves, housing, two side handles, curved isolation plate,
Funnel, collecting bag, support, hook.Described housing is elliptical cylinder-shape, and unequal two parts are separated into by curved isolation plate,
Housing tip is equipped with protective cover, is around equipped with telescopic bracket equipped with two side handles, lower section, thick beneficial to different coal seams is adapted to
Degree, semi-cylindrical hole sealing tube are connected with mozzle, and mozzle is connected with arc sieves, are divided into two by division board below sieves
Part, each section bottom are equipped with a funnel, are welded with four hooks around each funnel, lower section hangs with a collecting bag.
This coal dust screens collection device, and described protective cover is aluminum alloy material, and arc, detachably, top are equipped with handle.
This coal dust screens collection device, described arc sieves be woven into that pore size is 3mm-10mm with steel 8
Individual sieves, it can be changed according to required screen-aperture, with the horizontal 45 ° of angles.
This coal dust screens collection device, and described mozzle is aluminum alloy material, open circles taper, with the horizontal 40 °
Angle.
This coal dust screens collection device, and described housing is aluminum alloy material, is around welded with two handles, bottom is uniformly welded
There are four supports.
This coal dust screens collection device, and described support is extension type, is easy to regulation height, it is thick to adapt to different coals.
This coal dust screens collection device, and described funnel is aluminum alloy material, and four hooks are welded with below funnel.
The beneficial effects of the utility model are both to be avoided that dash dispels to coal dust, and and can makes coal dust Automatic sieve
Choosing, is easy to bulky grain ickings individually to weigh, the bulky grain quality or volume gone out by calculating sifting and overall quality of pc or body
Long-pending ratio, more accurately predict that the test point bump is inclined to.
This coal dust screening collection device is simple in construction, and cost is low, is easily installed, easy to use, practical.
