Abstract
An apparatus and method for filling boreholes with dry mass such sand, gravel, concrete and dry mortars or other similar materials from a deposit or a truck in blasting operations. The apparatus includes a container for storage of mass, conveying device with a conveyor screw for conveying the mass from the container into a hose and a compressed air supply for directing flow of the mass in the hose towards a dispenser. The compressor air supply is adapted to forcibly urge the mass into boreholes. The dispenser is adapted for positioning over the boreholes for filling with mass before blasting operations.
Claims10
An apparatus for filling a borehole with mass before blasting operations, the apparatus comprising:
- a container for storing mass;
- a hose for conveying the mass;
- a conveyor screw at bottom of the container for feeding the mass into the hose, a first end of the hose is connected to a conveyor screw exit;
- a whisk or vibrator mounted above the conveyor screw in the container for guiding the mass into the conveyor screw;
- a compressor having a first pipe for supplying highly compressed air into the hose;
- a vacuum pump for creating suction pressure at a second end of the hose opposite the first end of the hose;
- and
- a dispenser at the second end of the hose for pouring the mass into the borehole, wherein the first pipe from the compressor is connected into the hose immediately at the conveyor screw exit for directing flow of the mass towards the dispenser, and a second pipe from the compressor is attached into the vacuum pump to immediately provide extra air pressure for discharging the mass into the borehole from the dispenser.
A method of filling a borehole with mass before blasting operation using an apparatus
- a container for storing mass;
- a hose for conveying the mass;
- a conveyor screw at bottom of the container for feeding the mass into the hose, a first end of the hose is connected to a conveyor screw exit;
- a whisk or vibrator mounted above the conveyor screw in the container for guiding the mass into the conveyor;
- a compressor having a first pipe for supplying highly compressed air into the hose;
- a vacuum pump for creating suction pressure at a second end of the hose opposite the first end of the hose;
- and
- a dispenser at the second end of the hose for pouring the mass into the borehole, wherein the first pipe from the compressor is connected into the hose immediately at the conveyor screw exit for directing flow of the mass towards the dispenser, and a second pipe from the compressor is attached into the vacuum pump to immediately provide extra air pressure for discharging the mass into the borehole from the dispenser, the method comprising:
- supplying the mass into the containers;
- feeding the mass from the container into the hose by means of the conveyor screw at the same time by means of the whisk or vibrator;
- supplying the hose with highly compressed air from the compressor immediately after the conveyor screw exit through the first pipe;
- wherein the highly compressed air causes the mass to travel in the hose towards the dispenser;
- supplying the suction pressure to the second end of the hose from the vacuum pump;
- wherein the dispenser is filled with the mass supplied from the container;
- and
- supplying highly compressed air from the compressor through the second pipe to the dispenser through the vacuum pump to provide extra air pressure for discharging the mass into a first borehole from the dispenser.
