Description
SPECIFICATION
Cleaning device for a conveyor belt
This invention relates to a cleaning device for the material carrying surface of a conveyor belt.
Known cleaning devices comprise basically a cleaning blade urged into contact with the surface of the belt to be cleaned, and are usually fitted at the discharge end (the jib end) of a belt conveyor in order to remove material adhering to or embedded in the belt surface, thereby avoiding as much as possible adhering material being carried along by the return run of the belt. The material may for instance be coal fines, iron ore fines, sand, clay etc.
A problem with prior art cleaning devices is that they require frequent adjustment which is sometimes neglected or improperly effected, while if the device incorporates a spring loaded cleaning member as is often the case, the resulting extension or contraction of the spring to take up the wear on the cleaning blade, the spring(s) exert less force upon the contact area between cleaning blade and belt surface, resulting in a reducing cleaning efficiency as blade wear progresses.
Also, mounting arrangements for prior art cleaning blades have resulted in a relatively small amount of the blade being usable for cleaning purposes, e.g. the blade may have slotted holes for adjustment purposes, the holes accepting shanks of mounting bolts but restricting the amount of blade available for cleaning duties.
According to the present invention, a cleaning device for cleaning the material carrying surface of a conveyor belt comprises a rigid, elongate backing member of length approximating to the width of a belt surface to be cleaned, in use, by the cleaning device, an elongate cleaning blade of non-metallic, readily deformable material of length approximating to the width of the belt surface to be cleaned, in use, by the cleaning device, and having a longitudinal axis parallel to that of the backing member and spring means operable to displace the cleaning blade with respect to the backing member and into contact with the belt surface to be cleaned, in use, the backing member constantly providing a back support for the cleaning blade to preclude extrusion of the material of the blade beyond the backing member and, in use, through a gap between a portion of the backing member and belt surface to be cleaned. It will be appreciated that with this arrangement the spring loading urges the cleaning blade into contact with the belt surface to be cleaned, and hence any manual adjustment, in accordance with the rate of blade wear, is completely avoided due to the spring loading automatically producing a self-adjusting effect.
Preferably, the cleaning blade is of synthetic plastics material, e.g. polyurethane, ULON (Registered Trade Mark). In detail, the blade may be of laminated construction comprising a cleaning section of relatively soft polyurethane moulded integrally with a relatively hard plastics supporting strip. Thus, in section, when viewed from the side the cleaning blade is of narrow angle "V, '-section. The hard supporting strip is of inverted "V' '-section, mating exactly with the soft cleaning section, the whole forming a rectangular section cleaning blade of length appropriate for the width of belt to be cleaned. The supporting strip in fact provides virtually no cleaning action due to poor wearing qualities but it does stiffen the cleaning section and acts as an antiextrusion device.
Preferably, the cross-section area of the cleaning blade or at least a section of the cleaning blade that effects cleaning is not constant but decreases as wear takes place.
Thus, the decreasing effect of the spring means on the cleaning blade as wear occurs is countered by the decreasing blade area in contact with the belt surface, which thereby ensures that the optimum loading of the cleaning blade on the belt surface is maintained throughout the life of the cleaning blade.
The spring means may be operable either in the intended direction of movement of the cleaning blade, in use, or laterally with respect to this direction. In the former case, the spring means may comprise a plurality, e.g.
four, coil compression springs, while in the latter case the spring means may comprise a single, laterally extending spring in either tension or compression. With a laterally operable spring means, the blade may be displaceable by means of a horizontal wedge or bell crank to change the direction of force from horizontal to vertical whereby a laterally extending spring, having a length almost equal to the width of the conveyor drum, may be employed and in consequence, this spring will contract (or extend) through a very small range.
Conveniently, the backing member is of "L' '-section when viewed from the side, the vertical limb being set generally radially with respect to the return drum of the belt conveyor, this limb constituting the back support.
The backing member is preferably provided with side plates so as to define an open, box like assembly with a base, two sides and a back, in which assembly the cleaning blade is vertically displaceable under the influence of the spring means. The side plates of the backing member may have drilled or threaded holes by which the cleaning device is mountable on the rigid structure of the conveyor.
Additionally, to prevent removed material adversely affecting the action of the springs and/or the floating movement of the blade under the urge of the springs, which movement will be either for adjustment purposes in accordance with blade wear or to accept more readily movement past the blade of belt fasteners, a shroud may additionally be carried by the blade carrier. The shroud may comprise a length of surplus belting, a length of synthetic plastics sheeting etc., or a plate of steel or other rigid material having an inwardly bent top edge, which with the back support of the backing member, defines a gap through which the cleaning blade can emerge.
Preferably, the blade is mounted along one longitudinal edge in a blade carrier. In this case the spring means may be operable between the blade carrier and the backing member. Thus, due to the absence in the blade of any slotted holes, virtually the full width of the blade is usable for cleaning purposes, with the exception of course of the longitudinal edge by which the blade is mounted in the blade carrier. The blade carrier may comprise a length of angle iron with a clamping strip co-operable with one limb to grip the longitudinal blade er je therebetween by means of a plurality of clamping bolts.Preferably, the blade carrier incorporates a plurality of guide rods, (e.g. extending downwardly from the horizontal limb if the blade carrier is of angle iron) and the backing member incorporates a corresponding number of holes, with coil compression springs interposed between the backing member and the blade carrier. Additional guide rods may be provided and fitted with stops to limit the upward travel of the cleaning blade. To facilitate compression of the springs as an aid to fitting the device to a belt conveyor, the blade carrier may be provided with a threaded bar or tube to receive the shank of a bolt passed through the horizontal limb of the backing member, the bolt being rotated to draw the blade carrier and hence the blade, against the action of the spring means, to the lowest extremity of travel. After fitting of the device, the bolt is of course removed.
Varying materials, and their condition, being conveyed require different pressures in order to clean the belt surface satisfactorily and in some cases there may be a requirement to over-ride the built in method of maintaining constant blade pressure. Accordingly, variation in setting pressure may be achieved by the insertion of a pressure plate between spring means and the horizontal limb of the backing member. Changes in tension are made by bolts passing through the pressure plate into blocks fitted to the inside of the back plate which are drilled and screwed to suit. The operator may adjust the tension as required by the application of a key through the holes provided in the horizontal limb of the backing member on to the bolt heads. Turning the heads to increase or decrease setting pressure.Alternatively, setting pressure adjustment may be effected by the use of individual adjusters on each spring. In detail, a steel cup in which the end of a coil spring locates is welded to the end of steel tube of suitable length which is threaded externally along its length. At the end of the tube remote from the cup a hole is drilled through radially to accept a tommy bar. Beneath the horizontal limb of the backing member and co-axial with the guide rod hole is fixed a collar threaded internally to mate with the threaded tube. Assembly is effected by screwing the tube downwards into the collar and the spring is then fitted into the cup, followed by the guide rod through the spring and tube.The exposed thread may be protected by a suitable length of heat shrink or other suitable material while adjustment of the spring tension is obtained by inserting a tommy bar into the hole provided and turning the tube until desired cleaning blade to belt pressure is obtained.
In certain circumstances, the protuberance of belt fastening elements from the surface of the belt to be cleaned may preclude the positioning of the upper portion of the backing member in such proximity to the belt surface to be cleaned that optimum cleaning conditions cannot be attained. In such circumstances, it is recommended that a strip of relatively hard, synthetic plastics material is interposed between the backing member and the cleaning blade, the strip projecting beyond the upper portion of the backing member and incorporating slots for positional adjustment purposes.Conveniently the strip, of length approximating to the cleaning member, is bolted to the backing member and initially adjusted close to the surface to be cleaned to ensure that extrusion of the material of the cleaning blade through the gap between the upper portion of the backing member and the belt surface to be cleaned, does not occur.
The invention will now be further described, in greater detail, by way of examples with reference to the accompanying drawings, in which:

In all Figures, like components have been accorded like reference numerals.
A cleaning device 1 is intended to clean adhering material from a surface 2 of a conveyor belt 3 passing around a return drum 4, the device 1 being arranged both radially with respect to the drum 4 and vertically beneath the latter.
The cleaning device 1 comprises basically a rigid, elongate backing member 5, having a length approximating to the width of the belt 3, an elongate cleaning blade 6, and spring means 7 operable to displace the blade 6 with respect to the backing member 5.
In detail, the backing member 5 is of sheet steel bent to "L" section to provide a vertical limb 8 constituting a back support for the blade 6 and a horizontal limb 9, each end of the backing member 5 terminating in a side plate 10 to define an open, box-like assembly, the side plates 10 having holes 11 by which the cleaning device 1 is mounted on rigid structure (not shown) of the conveyor.
The blade 6 is of laminated construction comprising a cleaning section 1 2 of relatively soft polyurethane moulded integrally with a supporting strip 1 3 of relatively hard plastics, the section 1 2 being of narrow angle "V" section tapering away from the belt surface 2, and the strip 1 3 being of inverted "V" section to form a rectangular section blade 6.
The blade 6 is mounted along one longitu dinal edge 14 in a blade carrier 1 5 comprising a length of angle iron and a clamping strip 1 6 co-operating with one limb 1 7 of the angle iron to grip the blade edge 14 by means of bolts (not shown). The blade carrier 1 5 incorporates four guide rods 18, two located to each side of a centre line 1 9 of the blade 6, each guide rod 1 8 being secured at its upper end to the blade carrier 1 5 and slidably passing through an aperture 20 in the horizontal limb 9 of the backing member 5.In the embodiment of Figs. 1 to 5, the spring means 7 is operable in the intended direction of movement of the blade 6, i.e. in a vertical plane, and consists of a coil compression spring 21 surrounding each guide rod 18 and extending between the blade carrier 1 5 and the horizontal limb 9 with an interposed pressure plate 22. The latter is provided to enable adjustment of the spring tension to be effected. Thus a bolt 23 passing through an aperture 24 in the horizontal limb 9 with bolt head 25 bearing on the underside of the pressure plate 22 is screwed into a block 26 secured to the vertical limb 8 of the backing member 5.Furthermore, as shown in Figs. 2 and 4, additional guide rods 27 are located at each side of the cleaning device 1, between the pairs of guide rods 18, each additional guide rod 27 terminating in a stop 28 to limit the upward travel of the cleaning blade 6. As shown in Figs. 2 and 5, an internally threaded sleeve 29 is attached to the blade carrier 1 5 and may be employed by inserting a bolt 30 through an aperture in the horizontal limb 9 to draw the blade carrier 1 5 towards the horizontal limb 9 for assembly purposes on the conveyor structure. In order to protect the elements 18, 21, 23, 27 and 29 from ineffective operation due to the effects of material removed from the belt surface by the cleaning device, the blade carrier 1 5 is provided with a sheet metal shroud 31 having an inwardly bent top edge 32.
Obviously, it is important that the cleaning device be correctly mounted with respect to the belt surface 2 to be cleaned and a suitable location is shown in Fig. 1. It will be appreciated that under the loading of the springs 21, the blade 6 is urged into engagement with the belt surface 2 with the blade 6 sliding over the backing member 5, the upper edge of the latter being clear of the belt surface 2 to define a gap 33, but the gap 33 being so dimensioned that the constant back support provided on the blade 6 by the vertical limb 8 prevents the soft polyurethane of the cleaning section 1 2 being extruded through the gap 33 and this maintains the effectiveness of the cleaning device 1. It will be appreciated that as the springs 21 extend, upon the blade 6 wearing away and in particular the cleaning section 12, their loading on the blade 6 decreases.However, optimum cleaning conditions are maintained by reducing the crosssectional area of the cleaning section 1 2 which ensures that the same unit area sp'ring loading on the blade 6 is maintained.
In Figs. 6 to 9 is illustrated the possibility of the spring means 7 comprising a single laterally extending spring 21A. In the embodiment of Fig. 6, the spring 21A is in tension and is secured at each end on a pivot pin 34 carried by one arm 35 of a bell crank 36 pivotally mounted at 37 to the vertical limb 8, the other arm 38 being operable on the blade carrier 1 5. The device operates similarly in the embodiment of Fig. 7, except that the spring 21A is in compression and contained within a guide tube 39. In the embodiment of Fig. 8, the spring 21A is again in tension and at each end is connected by a tie 40 to a wedge shaped member 41 which co-operates with a first wedge piece 42 secured to the horizontal limb 9 and a second wedge piece 43 secured to the blade carrier 15, the elements 41, 42 and 43 transmitting the loading of the spring 21A to the blade 6.The device of Fig. 9 operates similarly except that the spring 21A is in compression.
The protuberance from the belt surface 2 of belt fastening elements may preclude the location of the vertical limb 8 with a gap 33 that guarantees a satisfactory anti-extrusion of the vertical limb 8, and the embodiment of Figs.
10 and 1 2 provide for such a circumstance.
Here a strip 44 of relatively hard, synthetic plastics material is interposed between the vertical limb 8 and the blade 6 and is provided with two slots 45 (one only shown) provided with teeth 46 engageable by a sprocket 47 whereby the position of the strip 44 with respect to the vertical limb 8 and the blade 6 may be adjusted. Usually a part of the upper edge of the strip 44 would be worn away by the belt fasteners but the latter would not be damaged and the remaining portions of the upper edge would assist in preventing extrusion.
In Fig. 1 2 is shown an alternative arrangement for individually adjusting the loading action of each spring 21 of the embodiment of Figs. 1 to -'~ 10 and 11. The lower end of each spring 2 1 is seated in a steel cup 48 welded to a steel tube 49 which is externally threaded and at an end remote from the cup 48 is provided with a hole 50. The tube 49 is screwed through an internally threaded collar 51 secured beneath the horizontal limb 9, and is co-axial with, and slidably receives the guide rod 1 8. A tommy bar is inserted into the hole 50 and the tube 49 and cup 48 rotated until the desired cleaning blade to belt pressure is obtained.
