Technical Field
The utility model relates to a blasting articles for use technical field, specific saying relates to a powder charge funnel for blasting.
Background
The blasting engineering is a technology which utilizes the huge energy instantaneously released by the explosion of the explosive to destroy or deform the medium around the explosive, thereby achieving a certain engineering purpose. In mining, drilling blastholes in ore or rock is known as rock drilling, loading blastholes with explosives, and breaking down the ore or rock from their matrix is known as blasting. The mine blasting engineering is a technology for breaking rocks and ores by using explosive explosion.
In the field of blasting engineering, blasting construction is completed by a series of procedures of hole distribution, drilling, hole measurement, charging, measurement, filling, network connection, warning, detonation and the like according to design. The types of explosive loaded are powder explosive, emulsion explosive, colloidal explosive and the like, and compared with other types, the powder explosive is the most widely used type at present.
In the face of the current strict and refined blasting construction site management, blasting construction technicians have higher and higher requirements on hole depth, hole distance and charging mode. Blasting operators have a common problem with different working surfaces, different rock properties, that is the degree of fragmentation of the treatment orifice. The main reasons for the broken orifice are that the gap between the shovel teeth will leave a layer of stone slag or broken stone on the blasting working face when the slag is removed mechanically, and the impact when the hole is drilled and opened, and the influence of lithology, such as soil inclusion, loose weathered rock, weathered shale, etc. In blasting construction of outdoor roadbeds, mines and the like, the poor specific gravity of the working surface environment is far more than that of smooth and convenient construction. Therefore, in the poor working face environment, when the powder is charged and filled in the blasting construction, the broken stone, the stone slag and the large stone at the hole opening are loosened and are transferred into the hole, so that the blasting accidents caused by reducing the hole depth, blocking the hole and blocking the powder charge are easily caused, and the blasting effect is directly influenced. Therefore, in order to ensure the safety of blasting and the blasting effect, a device for blasting is urgently needed.
SUMMERY OF THE UTILITY MODEL

Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the utility model discloses be fixed with round funnel lid on the cartridge case, when using, the cartridge case inserts in the big gun hole, and funnel lid is at the rubble, on the ballast, and be the triple of cartridge case internal diameter based on funnel lid diameter, avoided when the powder charge, the loose rubble in drill way when powder charge and clog, ballast and bold stone are transferred into downtheholely, avoided the bore depth to reduce, block the hole and cut off the blasting accident that the powder charge and arouse, the blasting effect has been guaranteed, it is very convenient also to make the powder charge and pack, only need directly fill can.
(2) The utility model discloses still fixed the medicine feed funnel at cartridge case top, further prevented rubble, slabstone from getting into the big gun hole along with the explosive when filling the powder charge together, further guaranteed blasting effect.
(3) The utility model discloses still set up the screen cloth in the hopper, because what pack is likepowder explosive or emulsion explosive, the likepowder explosive particle diameter is less, and emulsion explosive is like the gelatineous, and rubble, stone sediment particle diameter are great, utilizes the screen cloth to sieve both, can further guarantee to pack into the downthehole explosive purity of big gun, has further guaranteed blasting effect.
(4) The utility model discloses be provided with conduit and vibrating device, can pile when the screen cloth is blockked up to the screen cloth surface at the explosive, drive the screen cloth through the pulling conduit and vibrate on vibrator to descend the explosive with higher speed in the cartridge case.
(5) The utility model discloses can be used to emulsion explosive powder charge and powder explosive powder charge, be applicable to the unsatisfactory tunnel tunnelling blasting of various working face environment, the foundation ditch blasting, blasting in the pit, the road bed blasting, mine blasting etc., but its portability and durability wide application, easy and simple to handle, can play maximum guard action to the broken medium who solves the virtual sediment rubble of big gun hole drill way and the easy slump of drill way wall, also solved because of the piece stone falls into the stuck hole, virtual sediment rubble falls into the difficult problem that reduces the hole depth and cut off the powder charge, whole blasting construction effect that has promoted.
