Abstract

A supply system supplies an explosives material and comprises an explosives material delivery mechanism, a bin, a first outlet, a first removable cover, a port and an operation tool. The bin has an upper end, a lower end, and an interior volume that provides a first compartment for storing the explosives material. The first compartment has a corresponding lower end. The first outlet at the lower end of the first compartment feeds the explosives material from the first compartment to the explosive material delivery mechanism. The first removable cover is placed on a second outlet at the lower end of the compartment. The port is at the upper end of the bin by which the explosives material is loadable into the first compartment. The operation tool allows installation and removal of the first removable cover by way of the port without requiring any personnel to enter into the bin.

First claim

The invention claimed is:

1. An apparatus including a supply system that is adapted for supplying at least a first explosives material, the supply system comprising:
at least a first explosives material delivery mechanism;
a bin having an upper end, a lower end, and an interior volume that provides at least a first compartment for storing the first explosives material, the first compartment having a corresponding lower end;
two or more outlets provided at the lower end of the first compartment for feeding the first explosives material from the first compartment, wherein the two or more outlets include a first outlet for feeding the first explosives material to the first explosives material delivery mechanism, and a second outlet configured to feed explosive material to the first explosives material delivery mechanism or a second explosives material delivery mechanism;
at least a first removable cover for the second outlet, the first removable cover is installable on and removable from the second outlet;
a port provided at the upper end of the bin by which the first explosives material is loadable into the first compartment; and
an operation tool that is adapted to allow installation and removal of the first removable cover by insertion of the operation tool through the port without requiring any personnel to fully or partially enter into the bin.

2. The apparatus of claim 1 , wherein the supply system comprises:
the second explosives material delivery mechanism;
the second outlet provided at the lower end of the first compartment for feeding a second explosives material from the first compartment to the second explosives material delivery mechanism; and
a second removable cover for the first outlet, and installable thereon and removable therefrom, wherein the operational tool is adapted to allow installation and removal of the second removable cover by insertion of the operation tool through the port without requiring any personnel to fully or partially enter into the bin.

3. The apparatus of claim 2 , wherein the first explosives material delivery mechanism and the second explosives material delivery mechanism are of the same type as each other.

4. The apparatus of claim 1 comprising a mechanical platform for transporting the supply system.

5. The apparatus of claim 1 , wherein the bin comprises one or more non-configurable compartments, and the compartments may be formed by subdividing the bin.

6. The apparatus of claim 1 , wherein the first explosives material delivery mechanism comprises at least one of a pump or an auger.

7. The apparatus of claim 1 , wherein the first removable cover comprises at least one sealing, retention, or clamping mechanism to secure the cover over the second outlet, wherein the at least one sealing, retention, or clamping mechanism of the removable cover can be activated and deactivated using the operation tool without requiring any personnel to fully or partially enter into the bin, wherein the cover is optionally held against the second outlet by the at least one sealing, retention, or clamping mechanism engaging to an underside of a rim of the second outlet.

8. The apparatus of claim 1 , wherein the second outlet comprises a corresponding rim structure against which predetermined peripheral portions of an underside of the first removable cover rest when the first removable cover is seated over the second outlet.

9. The apparatus of claim 1 , wherein the first removable cover comprises a hatch engagement interface by which a tool engagement interface of the operation tool can matingly engage with and operate or manipulate the first removable cover.

10. The apparatus of claim 9 , wherein the hatch engagement interface includes or is a torque receiver for receiving torque from the operation tool, the hatch engagement interface being engageable by the tool engagement interface of the operation tool, and optionally the torque receiver includes or is a projection that extends from an upper surface of the first removable cover, and the tool engagement interface of the operation tool includes a torque transmitter for transmitting the torque to the torque receiver, and optionally the torque transmitter includes or is a recess or socket for engaging the projection of the removable cover.

11. The apparatus of claim 9 , wherein the hatch engagement interface includes or is a lifting-force receiver for receiving a lifting force from the operation tool, and which is engageable by the tool engagement interface of the operation tool, and optionally the lifting-force receiver includes or is a projection that extends from an upper surface of the first removable cover, and the tool engagement interface of the operation tool includes a lifting-force transmitter for transmitting the lifting force to the lifting-force receiver, and optionally the lifting-force transmitter includes or is a hook for engaging the projection of the removable cover.

12. The apparatus of claim 9 , wherein the hatch engagement interface includes or is a pushing-force receiver for receiving a pushing force from the operation tool, and which is engaged by the tool engagement interface of the operation tool, and optionally the pushing-force receiver includes or is a projection that extends from an upper surface of the first removable cover, and the tool engagement interface of the operation tool includes a pushing-force transmitter for transmitting the pushing force to the pushing-force receiver, and optionally the pushing-force transmitter includes or is a recess or socket for engaging the projection of the removable cover.

13. The apparatus of claim 1 , wherein the supply system comprises at least one shedder for placing over the first removable cover to facilitate or ensure flow of the first explosives material to other outlets that are uncovered, wherein the shedder includes a shedder engagement interface that allows the shedder to be positioned and removed using the operation tool by insertion through the port without requiring any personnel to fully or partially enter into the bin, wherein the shedder engagement interface optionally includes or is a projection that extends from an upper surface of the shedder.

14. The apparatus of claim 1 , wherein the operation tool comprises an elongate structure with a gripping portion at one end, and a cover engagement and actuation mechanism at the other end.

15. The apparatus of claim 1 , wherein the operation tool comprises an elongate structure with one or more robotic manipulators, actuators, or arms having a cover engagement and actuation mechanism, structure, or element, at a distal end.

16. The apparatus of claim 1 , wherein the operation tool extends downwardly through the port in a direction from the upper end of the bin to the lower end of the bin to engage the first removable cover.

17. A method for supplying at least a first explosives material comprising:
installing a first removable cover over a first outlet at a lower end of a compartment using an operation tool inserted through a port at an upper end of the compartment without requiring any personnel to fully or partially enter into the compartment, wherein the installing optionally includes applying a locking torque to the first removable cover using the operation tool;
loading the first explosives material into the compartment by the port;
storing the first explosives material in the compartment; and
feeding the first explosives material from the compartment to a first explosives material delivery mechanism by a second outlet at the lower end of the compartment.
