Abstract
A water supply system for a mining machine (1) of the continuous miner type comprises at least one rotatable mineral cutting drum (5); at least one water supply arm (9) adapted, in use, to extend forwardly from the mining machine (1) and terminating in a ring (6), the internal periphery (10) of which ring (6) is in close proximity to a portion of the external or internal arcuate periphery (53, 52) of the cutting drum (5). A circumferential water supply chamber (44) is defined between the internal periphery (10) of the ring (6) and the portion of the drum; and water sealing means (32) extends between the ring (6) and the portion of the drum (5) to minimise water leakage from the chamber (44). A water delivery port (45) is provided in the or each water delivery arm (9) for supplying pressurized water from a remote supply source to the chamber (44); and a water distribution network (38-41) of the drum (5) is in water flow communication with the chamber (44). The invention also includes a mining machine (1) provided with such a water supply system.
Claims
1. A water supply system for a mining machine (1 ) of the continuous miner type, the system comprising
(i) at least one rotatable mineral cutting drum (5) having a free end terminating in an end face ring (42); (ii) at least one water supply arm (8) adapted, in use, to extend forwardly from the mining machine (1) to a portion of the cutting drum (5) ;
(iii) a circumferential water supply chamber (22) defined between the arm (8) and the operational portion of the drum (5) ;
(iv) water sealing means (32) extending between the arm (8) and the drum (5) to minimise water leakage;
(v) a water delivery port (45) provided in the or each water delivery arm (9) for supplying water from a remote supply source to the drum (5); and
(vi) a water distribution network (39,40,41) of the drum (5) in water flow communication with the drum (5), characterised in that the water supply arm (8) is interposed between the free end of the drum (5) and the end face ring (42).
2. A water supply system as claimed in Claim 1 , wherein the or each arm (9) terminates in a ring (6), an internal or external operational periphery (10) of which ring (6) is in close proximity respectively to an external or internal portion (53,52) of the operational arcuate periphery of the cutting drum (5) .
3. A system as claimed in Claim 2, wherein the operational portion (53,52) of the drum (5) is a plain, arcuate periphery of the drum.
4. A system as claimed in Claim 2 , wherein the operational portion (53,52) of the drum (5) is a circumferential groove (22) provided in a portion of the arcuate periphery (10) of the drum (5) .
5. A system as claimed in any of Claims 2 to 4, wherein the sealing means (32) is static, is supported from the ring (6), and is in sliding sealing engagement with the drum (5) .
6. A system as claimed in any one of Claims 2 to 4, wherein the sealing means (32) is rotary, is supported from the drum (5), and is in sliding sealing engagement with the ring (6) .
7. A system as claimed in any preceding Claim, wherein the sealing means (32) is biased into sealing engagement.
8. A system as claimed in Claim 7, wherein the sealing means (32) is biased hydraulically by the water of the water supply system into sealing engagement.
9. A system as claimed in Claim 7, wherein the sealing means (32) is biased mechanically by spring means into sealing engagement.
10. A system as claimed in Claim 7, wherein the sealing means (32) is biased by the resilience of the material of the sealing means (33,34) into sealing engagement.
11. A system as claimed in any preceding Claim, wherein the sealing means (32) comprises a single ring, with opposed sealing arms (33,34).
12. A system as claimed in any of Claims 2 to 11, wherein the sealing means (32) comprises at least two axially spaced apart sealing rings (32) which are biased radially, or generally radially, into sealing engagement.
13. A system as claimed in Claim 4 and any claim appendant thereto, wherein the sealing means (32) at least partially penetrates the circumferential groove (22) and has arms '33,34) biased into sealing engagement with the rotating sides of the groove (22) by spring means (58), or by the resilience of the material of the seal, or hydraulically.
14. A system as claimed in Claim 4 and any Claim appendant thereto, wherein the groove (22) is provided with hardened wear surfaces or alternatively with replaceable wear elements (23,24).
15. A system as claimed in any preceding Claim, wherein the sealing means (23) and any associated components is/are insertable and removable as a cartridge.
16. A system as claimed in Claim 15, wherein the cartridge incorporates vibration dampening means (50).
17. A system as claimed in any preceding Claim, wherein water distribution from the chamber (22) is effected via a distributor ring (35) associated with the chamber and having a plurality of axially extending, static supply ports (36) which are alignable with receiving ports (37,38) of the drum (5) so that presence or absence of ports (37,38) provides for phased delivery over an arc.
18. A system as claimed in Claim 17, wherein the distribution ring (35) is hydraulically balanced with water pressure effective on various faces of the ring.
19. A system as claimed in any preceding Claim, wherein the chamber (22) is located adjacent the outermost end of an end drum (5) .
20. A system as claimed in any one of Claims 2 to 19, wherein the ring (6) at the terminal end of the or each water supply arm (9) is of a split construction, as is the water sealing means (23).
21. A mining machine of the continuous mining type, comprising a crawler chassis (2) with a pair of spaced-apart, elevatable drive arms (8) pivotable about a common transverse axis, projecting from the front of the chassis (2) and carrying a mineral cutting means comprising a pair of end cutting drums (5) and a central cutting device in the form of either a drum or endless cutting chain, wherein the or each end cutting drum (5) is provided with a water supply system, as defined in any preceding Claim.
22. A machine as claimed in Claim 21, wherein the or each water supply arm (9) extends to an end drum (5).
23. A machine as claimed in Claim 21 or 22, wherein the or each water supply arm (9) is/are attached externally to, or integrated internally into, the or each drive arm (4).
24. A machine as claimed in Claim 21 or 22, wherein the or each water supply arm (9) is/are supplementary to the or each drive arm (4) .
25. A machine as claimed in any one of Claims 21 to 24, wherein a single water supply arm (9) is provided extending to one drum (5) with the water then distributed to at least one other drum (5) .
26. A machine as claimed in any one of Claims 21 to 24, wherein two water supply arms (9) are provided extending individually to the two end drums (5) .
27. A machine as claimed in any one of Claims 21 to 26, wherein a dished end face ring (18) is provided at the free end of the drum (5), or of each end drum (5), beyond the water supply arm (9) .
