Definitions

  • the present invention relates to a plate conveyor, in particular but not exclusively, a plate conveyor for conveying material containing large lumps mixed with finer particulate material.
  • the won material typically contains large lumps of mineral mixed with finer particulate material.
  • a typical plate conveyor comprises a conveying bed defined by a plurality of side by side plate members which are hingedly connected to one another.
  • the conveying bed has an upper run upon which the won material is deposited at one end, viz. the loading end.
  • the deposited material is then transported by die moving conveying bed along the upper run to be discharged from the delivery end of the conveyor.
  • a general aim of the present invention is to provide a plate conveyor which is capable of transporting particulate material falling from the lower run of the conveying bed back to the upper run of the conveyor.
  • a plate conveyor having a continuous conveying bed guided to have an upper run extending between a loading end and a delivery end and a lower run located beneath the upper run, collection means located beneath the lower run for collecting finer particulate material falling from the lower run and transfer means formed on the conveying bed for transporting particulate material collected by the collection means away from the collection means and to said upper run.
  • the collection means comprises a flat bed extending along the length of said lower run.
  • the transfer means comprises a plurality of scraper bars extending laterally across the conveying bed, the scraper bars being spaced at desired locations along the length of the conveying bed.
  • the conveying bed comprises a plurality of plate members located side by side along the length of the bed, each plate being connected to a pair of drive transmission chains, each chain being formed in a continuous loop. Accordingly, the plates are flexibly connected to one another by the chains.
  • the scraper bars are located upon selected plates and project by a predetermined height above the conveying bed defined by the plates.
  • the scraper bars on the lower run are thus arranged to contact the flat bed to support the lower run of the conveying bed.
  • the weight of the plates whilst in the lower run act to press the scraper bars into contact with the upper surface of the flat bed and so enable the scraper bars to scrape particulate material along the surface of the flat bed and move it toward the loading end of the conveyor. Since adjacent plates are flexibly joined to one another, the plates located inbetween adjacent scraper bars sag downwardly toward the flat bed and so encourage particulate material, adhering and bridging adjacent plates, to fall onto the flat bed.
  • Preferably forwardly projecting weir plates are provided at each end of each scraper bar in order to discourage lateral movement of the finer particulate material during transport of material along the upper run.
  • FIG. 1 is a schematic side view of a plate conveyor arranged to feed material to a mineral breaker
  • Figure 2 is a plan view of a plate conveyor according to an embodiment of the present invention.
  • Figure 3 is a side view of the plate conveyor shown in Figure 2;
  • Figures 4a, 4b & 4c are partly broken away side views of the plate conveyor of Figure 3 showing in greater detail die loading end, a central region and the delivery end respectively;

  • FIG. 1 there is schematically shown a plate conveyor 10 of the type witii which the plate conveyor of the present invention is particularly concerned.
  • the plate conveyor 10 is arranged to feed material, such as material being mined in an open cast mine, to a mineral breaker 12.
  • the won material typically includes large lumps of mineral mixed with finer lumps and particulate material such as soil and sand.
  • the mineral breaker 12 may be a twin roll miner sizer of the type described in our European Patent No. 0 167 178.
  • the conveyor 10 includes a pair of sprocket drums 14, 16 around which the conveying bed 18 is trained.
  • One of the sprocket drums is driven by a motor (not shown) so as to move the conveying bed 18 in the direction of arrow F.
  • the conveying bed 18 dierefore has an upper run 19 and a lower run 20 extending inbetween the drums 14, 16.
  • the end of the conveyor 10 adjacent to drum 14 is the loading end and the end adjacent to die drum 16 is me discharge or delivery end.
  • material deposited at me loading end (as indicated by arrow L) is transported on die upper run 19 of the conveying bed to die delivery end to be discharged into the mineral breaker 12 as indicated by arrow D.
  • hopper side walls 24 are provided to retain and guide transport of material along me conveyor 10 for discharge.
  • a plate conveyor 50 according to a preferred embodiment of the invention is illustrated in Figures 2 to 11 wherein.
  • the conveying bed 18 of conveyor 50 comprises a plurality of side by side conveying plates 60, one of which is illustrated in detail in Figures 9 to 11.
  • Each conveying plate 60 is secured, preferably by bolts 61 , to a pair of spaced transmission chains 162, 163.
  • the chains 162, 163 are each formed into a continuous loop and are trained about sprocket drums 14, 16.
  • the chains 162, 163 are supported on rollers 164 whilst passing along die upper run 19.
  • Each plate 60 has an elongate plate body 62 which preferably has a plurality of upstanding ribs 63 for assisting gripping of material deposited onto the upper run 19.
  • Each plate 60 is preferably formed from rolled steel which enables the sectional shape and dimensions of die plate to be accurately formed.
  • each outer end of the plate body 62 there is provided an upstanding side plate 66.
  • the side plates 66 assist in guiding movement of the conveying bed 18 by restricting lateral displacement and also help to restrict flow of finer particulate material over me sides of the conveying bed 18.
  • the conveying plate 60 illustrated in Figures 9 to 11 further includes a scraper bar 70 which is preferably integrally formed with the plate body 62.
  • the bar 70 extends continuously along die lengtii of the plate body 62 but terminates inboard of the respective side plates 16 to define a gap 72. As more clearly seen in Figures 5, gaps 72 accommodate the lower side edges of hopper walls 24.
  • a pair of weir plates 74 are preferably provided, located at respective ends of each scraper bar 70.
  • the weir plates 74 extend forwardly, ie. extend away from the scraper bar in die direction of movement F of me conveying bed 18 and serve the purpose of discouraging particulate material which is being pushed forward by the scraper bar from spilling sideways past die lower side edges of die hopper walls 24 toward die side plates 66.
  • the conveyor 50 has a main frame 51 and diis includes a pair of rails 52 which co-operate widi the side plates 66 to guide the conveying bed 18 as it travels along its upper run 19.
  • the rails 52 extend continuously along each side of the upper run 19 and each include a vertical side wall 53.
  • each side wall is closely spaced from the outer side face 66a of the facing side plate 66.
  • opposed side faces 53a, 66a co-operate to guide longitudinal movement of the upper run 19 of the conveying bed.
  • face 53a and/or face 66a is treated to provide a hard wearing face which is resistive to abrasive wear.
  • Each rail 52 has a bottom wall 54 which extends inwardly underneadi me side margins of the conveying bed 18.
  • a rib 56 is provided on die bottom wall 54 and is located inboard of die side wall 53 to diereby define a shallow open topped channel 156 which extends continuously along me rail 52.
  • each plate 60 is provided widi a support block 67, preferably formed of steel, which is located so as to be received witiiin the channel 156 and be of a size so as to preferably extend across die majority of die widdi of the channel 156.
  • the block 67 is preferably chosen so as to have a height sufficient to support the plate 60 above rib 56 widi clearance. Accordingly the weight of plate 60 and any load carried diereby ensures that blocks 67 slidingly abut against the upper surface of die bottom wall of channel 56 and accordingly act as scrapers to move any fine particulate material which may have passed by die lower edges of the hopper walls 24 and die side plates 66 along die channel 156 to be discharged at die discharge end of me conveyor.
  • the plates 60 enter into a collection means 80 which extends continuously along die lower run 20 of die conveying bed 18.
  • the collection means 80 includes a flat bed 81 preferably formed in longitudinal sections located end to end along die lengtii of die flat bed 81. Each section is preferably formed from a plate of steel.
  • the flat bed 81 is located adjacent to die lower run 20 such that the scraper bars 70 are able to rest upon die flat bed 81 and thereby support the weight of the lower run 19.
  • any particulate material which has adhered to me conveying bed 18 and been transported to die lower run 19 is no longer supported on die conveyor plates 60 and so is likely to fall upon die flat bed 81.
  • the material which has fallen onto the flat bed 81 is scraped along the flat bed 81 by the scraper bars 70 and so moved toward me loading end of the conveyor.
  • the conveyor 50 is provided at its loading end with a cowling 90 which covers the run of die conveying bed 18 as it passes around me sprocket drum 14.
  • the cowling 90 is closely spaced from the conveying bed such mat me scraper bars 70 are able to transport the material being scraped diereby around die sprocket drum 14 and to die upper run 19.
  • the material scraped by each scraper bar 70 will diereafter be conveyed to die discharge end of the conveyor for discharge.
  • scraper bars 70 support die weight of die lower run 20 of die conveying bed, mey are maintained in sliding abutment with die upper surface of me flat bed 81 and so prevent a build up of material on the bed 81.
  • scraper bars 70 are preferably only provided on selected conveying plates 60. Accordingly, diose plates 60 not having scraper bars 70 are not directly supported on die flat bed 81 and so the conveying bed 18 located inbetween adjacent scraper bars 70 tend to sag toward die bed 81. This is illustrated in Figure 4b. This sagging action helps to dislodge particulate material adhering to the bed 18 and encourage it to fall onto the flat bed 81.
  • An upstanding rib 85 extends continuously along each side of me flat bed 81 and is located at a position so as to be received witiiin gaps 72; the ribs 85 diereby acts to resist sideways spillage of the particulate material whilst it is being scraped along die bed 81 by scraper bars 70 and also act to keep gaps 72 clear of material.
  • Upstanding side plates 95 are provided along each side of die bed 81 for co-operation with side plates 66 to guide longitudinal movement of the conveying bed 18 along die lower run 20.
  • die height of me ribs 85 are less than die height of side walls 66 such tiiat when tiie conveying bed 18 sags inbetween adjacent scraper bars 70, intermediate plates 60 are supported by top edges of die side plates 66 abutting the upper surface of the bed 81.
  • die side plates 66 substantially fill the widdi of the channel 97 defined between bed 81, rib 85 and adjacent side plate 95 and so tiiese side plates 66 act to scrape material along channel 97 in order to keep it clear.
