Abstract
A kind of blasting hole backfills funnel, including infundibular body, discharge nozzle, the bottom of infundibular body connects with discharge nozzle, it is characterized in that, installation waste outlet groove outside waste outlet, waste outlet is provided with the side of infundibular body, mesh screen is tilted and is covered in infundibular body, the low side of mesh screen is concordant with waste outlet bottom, and waste outlet groove is parallel with mesh screen face.Blasting hole of the present utility model backfills funnel, without spending manpower and materials to find suitable stuffing, even if the stuffing in infundibular body is mixed into the miscellaneous stone of bulk, also it cannot be introduced into blasting hole, from discharge nozzle fall into blasting hole in stuffing be qualified stuffing, ensure blasting hole backfill quality, it is ensured that void will not be produced and fill out and cause filling not in place, be conducive to improving backfilling working efficiency.
Description
Technical field
The utility model is related to a kind of blast working instrument, specifically a kind of blasting hole backfill funnel.
Background technology
It is mostly relative using a diameter of 40~140mm apertures during the bursting works such as small mine, stone pit and highway subgrade
Less blasthole, due to working face clear up it is unqualified, cause powder charge, networking connection finish after carry out blasthole backfill when, easily go out
Existing hole clipping, filling are not in place, and this is a kind of breakneck phenomenon, not only reduce explosive energy utilization rate, and easily produce punching
Hole, slungshot, or even the bulk stuffing fallen into hole, may cause detonator in hole, potential safety hazard and the accidents such as blind big gun occur.
The content of the invention
The purpose of this utility model is just to provide one kind using safety, operating efficiency height, and backfill blasthole can be prevented to be mixed into greatly
The blasting hole backfill funnel of block stone.
Blasting hole of the present utility model backfills funnel, including infundibular body, discharge nozzle, bottom and the discharge nozzle phase of infundibular body
Connect, it is characterised in that installation waste outlet groove outside waste outlet, waste outlet is provided with the side of infundibular body, mesh screen, which is tilted, to be covered
Cover in infundibular body, the low side of mesh screen is concordant with waste outlet bottom, and waste outlet groove is parallel with mesh screen face.
Blasting hole of the present utility model backfills funnel, in use, discharge nozzle is directed at blasting hole, stuffing is sent into and leaked
In bucket body, stuffing passes through the screening of mesh screen, and underproof stuffing is discharged from waste outlet groove, falls the ground beside blasthole
Face；Qualified stuffing（Diameter<2cm）Fallen vertically from mesh screen bottom, fall into discharge nozzle, finally fall into blasting hole as filling out
Plug material.
Blasting hole of the present utility model backfills funnel, without spending manpower and materials to find suitable stuffing, leaks
Even if the stuffing in bucket body is mixed into the miscellaneous stone of bulk, also cannot be introduced into blasting hole, from discharge nozzle fall into blasting hole in fill out
It is qualified stuffing to fill in material, it is ensured that blasting hole backfills quality, it is ensured that will not produce void and fill out and cause filling not in place, favorably
In raising backfilling working efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- infundibular bodies；2- handles；3- discharge nozzles；4- waste outlet grooves；5- waste outlets；6- mesh screens.
