Definitions

  • This invention relates to a feeder/conveyor assembly and more particularly to a feeder pan arrangement for the same.
  • Apron feeders are extensively used in the mining industry for feeding heavy, abrasive ores from storage bins to downstream processing equipment.
  • the apron feeders include steel feeder pans that are supported and driven by track chains.
  • apron feeders of this type are well suited to conveying larger rocks and lumps of ore, finer material can leak between the steel feeder pans.
  • the feeder pans are not easy to clean. Fine material can adhere to the surface of the steel feeder pans and, as a result, be‘carried back’ through the feeder. The adhered material can also cause spillage beneath the apron feeder. The leaked and spilled material beneath the apron feeder requires an additional mechanism to collect it.
  • Conveyer belt feeders connected to steel supporting cross-bars that are driven by track chains are known and, when used to transport ore material, can prevent leakage of fine material or, potentially, liquid through the conveying surface, providing a significant reduction in the carry back of fine material.
  • the belt surface of conveyer belt feeders wears much faster than steel and can become ripped or punctured by larger rocks. Replacement of a worn belt can be time consuming and difficult.
  • the present invention aims to provide an improved feeder apparatus and to mitigate one or more of the above problems associated with existing feeders at least to an extent.
  • the present invention provides a conveyor feeder apparatus comprising a plurality of cross-bars arranged in a closed loop and connected to at least one track chain for providing drive thereto; a plurality of feeder pans, each feeder pan having a carrying surface and being supported by a cross-bar of the plurality of cross-bars for conveying transport therewith; and a seal disposed between and adapted for sealing connection between the carrying surfaces of adjacent feeder pans.
  • each feeder pan includes a fore side and an aft side, the fore side and the aft side each including a seal retention groove, and wherein the seal has a first protrusion adapted for retention in the seal retention groove of the aft side of a first feeder pan, a second protrusion adapted for retention in the seal retention groove of the fore side of an adjacent feeder pan and a third protrusion adapted to provide a sealing connection between the carrying surface of the first feeder pan and the carrying surface of the adjacent feeder pan.
  • each feeder pan includes a fore side and an aft side, the fore side and the aft side each including an upper flange and a recessed base portion; each cross-bar has an upper surface adapted for receiving the recessed base portion therein such that a seal retention gap is formed between the upper flange and the upper surface of the cross-bar; wherein the seal has a first protrusion adapted for retention in the seal retention gap formed between the upper flange of a first feeder pan and the upper surface of a first cross-bar, a second protrusion adapted for retention in the seal retention gap formed by the upper flange of an adjacent feeder pan and the upper surface of an adjacent cross-bar, and a third protrusion adapted to provide a sealing connection between the carrying surface of the first feeder pan and the carrying surface of the adjacent feeder pan.
  • the conveyor feeder apparatus includes a scraper adapted for cleaning material from the carrying surface of each feeder pan as it is conveyed past the scraper.
  • the carrying surface of each feeder pan is generally convex. In this manner, the carrying surface can be easily accessed by the scraper to clean off material that has adhered to the carrying surface, reducing the amount of material that is carried back around the conveyor feeder apparatus.
  • the feeder pan comprises a wing at either side of the carrying surface that is adapted for containing material to be transported on the carrying surface of the feeder pan.
  • the feeder pan may also include a pair of fastening flanges arranged externally of the wings, the flanges each being adapted for receiving a fastening member therein for attachment of the feeder pan to the cross-bar. This arrangement separates the bolts from the carrying surface, minimising the possibility of fine material becoming stuck to the fastening members or into small gaps between fastening members and the flanges. It also ensures that the scraper can operate effectively to clean the carrying surface.
  • FIG. 1 is a schematic side view of a portion of a conveyor feeder apparatus according to a first embodiment of the invention
  • FIG. 2 is a schematic side view of a portion of a conveyor feeder apparatus according to a second embodiment of the invention.
  • Fig. 3a is a side profile view of the seal of the embodiment of Fig.1 ;
  • Fig. 3b is a side profile view of the seal of the embodiment of Fig. 2;
  • FIG. 4 is a schematic side view of a discharge end of the conveyor feeder apparatus of either the first or the second embodiment of the invention.
  • FIG. 5 a is a schematic front view of a wing and flange of a feeder pan in accordance with the invention.
  • Fig. 5b is a side elevation view of the feeder pan of Fig. 5a; and [0022] Fig. 6 is a front view of an upper platform of the cross-bar.
  • Fig. 1 shows a schematic partial side view of a first embodiment of a conveyor feeder apparatus 1.
  • the conveyor feeder apparatus 1 includes a plurality of cross-bars 10 supporting a plurality of feeder pans 30. Four of the cross-bars 10 are shown in side view in Fig. 1 , attached to four corresponding feeder pans 30.
  • Each cross-bar 10 has a generally T-shaped profile, having an upper platform 12 and a central arm 14 depending from the upper platform 12 towards an interior of the conveyor feeder apparatus 1.
  • the upper platform 12 of each cross-bar 10 is generally rectangular in plan view and is attached at its shorter sides to a pair of parallel track chains 50, seen in Fig.
  • each cross-bar 10 has a fore end 15 and an aft end 16.
  • An upper surface 18 of the upper platform 12 of each cross-bar 10 includes an upper recess 19 in which the feeder pan 30 is received.
  • the feeder pans 30 of the first embodiment of the invention comprise of machined steel components having a rectangular base 31 corresponding to the plan area of the upper recess 19 so as to be received therein with a close fit. Above the base 31, the feeder pan 30 extends in length beyond the length of the upper platform 12.
  • the feeder pans 30 have an upper carrying surface 35 with a convex profile, when viewed in side view, upon which material to be transported rests during operation of the conveyor feeder apparatus 1.
  • the feeder pan 30 has a fore side 39 and an aft side 37, each of which include a seal retaining groove 40 extending the width thereof.
  • any two feeder pans 30 of the plurality of feeder pans 30 is received in the upper recess 19 of the upper platforms 12 of a corresponding pair of cross-bars 10, the aft side 37 of a first of the two feeder pans 30 lies close to the fore side 39 of a second or adjacent feeder pan 30, producing a small gap between the two sides.
  • the gap is filled with a seal 60.
  • the seal 60 comprises an elongate rubber element that extends between the aft side 37 of the first feeder pan 30 and the fore side 39 of the adjacent feeder pan 30.
  • the seal 60 best seen in Fig. 3a, has a profile consisting generally of three protrusions; a first fore protrusion 62, a second aft protrusion 64 and a third upper protrusion 66.
  • the first fore protrusion 62 is rounded to fit with a sealing fit into the seal retaining groove 40 of the aft side 37 of a feeder pan 30 so as to be retained therein.
  • the second aft protrusion 64 is rounded to fit with a sealing fit into the seal retaining groove 40 of the fore side 39 of a feeder pan 30 so as to be retained therein.
  • the upper protrusion 66 has a tapered shape to fit the gap between an upper portion of the aft side 37 and an upper portion of the fore side 39 with a sealing fit so that fine material does not leak into the gap between the feeder pans 30.
  • each protrusion 62, 64, 66 is a small notch 67 cut into the seal 60 to allow the flexing of the protrusions 62, 64, 66 relative to one another as the feeder pans 30 are transported around the conveyor feeder apparatus 1.
  • the seal 60 is made of rubber or other flexible material such as soft polyurethane that allows high amounts of strain with minimal strain hardening, or fatigue, effects. As such, the seal 60 is capable of flexing with the transport of the feeder pans 30 around the conveyer feeder apparatus 1 to maintain the sealing fit between the carrying surfaces 35 of the feeder pans 30 to which it is fitted. The seal 60 therefore provides a sealing fit between the carrying surfaces 35 of the feeder pans 30 even whilst the feeder pans 30 are in motion.
  • Each of the feeder pans 30 are attached to the upper platform 12 of the cross bar 10 using bolts 65 (seen in Fig. 6) fastened through holes 41 (best seen in Fig. 5a, Fig. 5b) drilled through both the feeder pan 30 and the upper platform 12.
  • the feeder pan 30 includes a wing 43 at either side of the carrying surface 35 as shown in Fig. 5 a and Fig. 5b, so as to contain material being transported on the carrying surface 35 and prevent it falling off the side edges. Externally of the wings 43 is a horizontal flange 45 that includes the drilling holes 41. Fastening the feeder pan 30 to the cross-bar externally of the carrying surface 35 minimises the possibility of fine material collecting around the holes 41 and the bolts 65 that can cause carry back or spillage.
  • Fig. 2 shows a schematic partial side view of a second embodiment of the conveyor feeder apparatus 1.
  • the second embodiment is very similar to the first embodiment but differs in some details of the feeder pan, cross-bar and seal as will be described below.
  • the second embodiment of the conveyor feeder apparatus 1 includes a plurality of cross-bars 100 supporting a plurality of feeder pans 300. Four of the cross-bars 100 are shown in side view in Fig. 2, attached to four corresponding feeder pans 300.
  • the cross-bars 100 are substantially identical to the cross-bars 10 and include an upper platform 120 that has an upper recess 190 that is substantially identical to the upper recess 19 and a central arm 140 that is substantially identical to the central arm 14.
  • An upper surface 180 of the cross-bars 100 is machined to a horizontal surface fore and aft of the upper recess 180.
  • the feeder pans 300 of the second embodiment of the invention comprise machined steel components having a rectangular base 310 corresponding to the plan area of the upper recess 190 of the upper platform 120 so as to be receivable therein with a close fit.
  • the feeder pans 300 have an upper carrying surface 350 with the same convex profile as the feeder pans 30, when viewed in side view, upon which material to be transported rests during operation of the conveyor feeder apparatus 1.
  • the feeder pans 300 differ from the feeder pans 30 in that a fore side 370 and aft side 390 of the feeder pan 300 do not have seal retaining grooves, but instead consist of an upper flange 330 that undercuts directly beneath the carrying surface 350 to the narrower base 310 profile.
  • a seal 600 has a first fore protrusion 620 shaped for a sealing fit in the seal retention gap formed by the upper flange 330 of a first feeder pan and the upper surface 180 of a first cross-bar 100, so as to be clamped and retained between the two.
  • a second protrusion 640 is shaped for clamping retention in the seal retention gap formed by an underside of the upper flange 300 of an adjacent feeder pan and the upper surface 180 of the adjacent cross-bar 100.
  • a third protrusion 660 is tapered to provide the sealing connection between the upper flanges 330 and hence the carrying surfaces 350 of the first feeder pan 300 and the adjacent feeder pan 300. Between each protrusion 620, 640, 660 is a small notch 670 cut into the seal 600 to allow the flexing of the protrusions 620, 640, 660 relative to one another as the feeder pans 300 are transported around the conveyor feeder apparatus 1.
  • the seal 600 also includes an inverted v- shaped pair of protrusions 680 in an underside thereof that rest over the edges of a fore side 150 and an aft side 160 of the upper platform 120 and assist to retain the seal 600 in position as the feeder pans 300 are transported around the feeder conveyor apparatus.
  • the feeder pans 30, 300 are described in the embodiments above as being made from steel. Steel provides for the ability to handle large sharp rocks without damage to the conveying surface and the pans can transfer large shear loads without sustaining damage. However, the skilled person will appreciate that the feeder pans 30, 300 can be manufactured from a number of materials, including steel or a steel alloy in a high load/wear application or plastic, rubber or polyurethane for lighter duty applications.
