Definitions

  • the present invention relates to an agricultural conveyer and, in particular, to a conveyer for use in grain and fertiliser handling.
  • Conveyors have been used in the transportation of grain since the 1800's.
  • Conveyers are ideal appliances in that they can run at relatively high speeds with a moderate expenditure of power.
  • Conveyers of this type may be portable or fixed depending on their required purpose, and typically comprise a continuous belt fitted within a housing which includes both receiving and delivery means.
  • Such conveyors can be used to handle grain from or into granaries, or simply to feed bins or sections of warehouses.
  • conveyors and augers are used during harvesting of grain, for example, where grain is required to be transported from the harvester itself to a storage cart moving alongside the harvester.
  • conveyors of this kind are ideal for use with grain, they are also capable of rendering good service in handling other materials such as seeds and fertiliser, as well as heavier materials such as coal and minerals. Accordingly, the scope of the present invention is not to be limited to applications associated only with grain.
  • a conveyor of the type used to transport material said conveyor characterised by: a longitudinal housing; a feeding means associated with a lower end of said longitudinal housing into which said material is adapted to be fed; and a longitudinal conveyor belt adapted to receive said material from the feeding means and transport the material to an upper end of said longitudinal housing where the material may be discharged, said conveyor belt including longitudinal borders on either side thereof said borders adapted to prevent the material from contacting said housing when the conveyor belt is moving.
  • the present invention therefore relates to a conveyor for transporting agricultural material such as grain, seed and fertiliser from a
  • said conveyor belt further includes a plurality of cleats which are spaced apart along the length of the conveyor belt and which extend transversely in between said borders.
  • said conveyor belt is continuous and is maintained in tension by a first and second roller around which said conveyor belt extends, said first roller positioned at the lower end of said longitudinal housing and said second roller positioned at the upper end of said longitudinal housing.
  • said first roller is a belt tension roller that is both moveable and lockable along at least a portion of said longitudinal housing
  • said second roller is a drive roller coupled to a drive means for actuating movement of said conveyor belt
  • tensioning of said belt may be achieved by moving said first roller away from said second roller, and de-tensioning of said belt may be achieved by moving said first roller toward said second roller.
  • said longitudinal borders of said conveyor belt are flexible and also corrugated so that they may appropriately expand when the conveyor belt circles around said first or second roller and compress when said conveyor belt is flat.
  • said longitudinal housing encloses said conveyor.
  • said longitudinal housing is of a rectangular cross-section including side walls adjacent the edges of said conveyor belt.
  • said drive means is a hydraulic motor mounted to said longitudinal housing and coupled to said drive roller via a pulley system.
  • said drive means further includes a hydraulic control valve which may be adjusted to control the amount of hydraulic fluid entering the hydraulic motor.
  • said feeding means is a catchment hopper.
  • material is discharged from the upper end of said conveyor into an outlet nozzle and downwardly through a distributor hose.
  • a conveyor for use in handling agricultural material said conveyor characterised by: an enclosed elongated housing including an upper end and a lower end, said lower end having associated therewith a catchment hopper into which material to be conveyed is to be fed; a conveyor belt adapted to move longitudinally adjacent side walls of said enclosed elongated housing, said conveyor belt adapted to receive said material entering said catchment hopper and transport the material to said upper end of the housing for discharge therefrom, said conveyor belt including flexible corrugated borders extending outwardly therefrom said borders adapted to prevent said material from contacting said side walls of the housing when the conveyor belt is rotating.
  • said conveyor belt further includes a plurality of transverse cleats which are spaced apart along the length of the conveyor belt.
  • said cleats extend outwardly from said conveyor belt at an angle of approximately 15 degrees.
  • said conveyor may be fixed or portable.
  • Figure 1 illustrates a perspective view of a conveyor in accordance with the present invention
  • Figure 2 illustrates a cross-sectional side view of the conveyor of Figure 1;
  • Figure 3 illustrates an enlarged perspective view of the upper or discharge end of the conveyor of Figure 1;

  • Figure 5b illustrates a top view of the portion of cleated and bordered belt of Figure 5a;
  • Figure 6 illustrates a perspective view of the conveyor of Figure 1 being used according to one embodiment of the present invention.
  • FIGS 1-2 illustrate the conveyor 10 of the present invention.
  • the objective of the grain and fertiliser conveyor 10 is to transport particulate material quickly and efficiently whilst minimising damage to the material being transported.
  • the conveyor 10 is illustrated in some of the drawings as being fixed to a pivotable mounting bracket 12 at an angle of approximately 45 degrees, however, it is to be understood that the angle of the conveyor 10 may be adjusted to suit different situations, and that alternate mounting means may be used.
  • the conveyor may well be portable whereby its mounting frame is supported above wheels.
  • the conveyor 10 includes an elongated housing or chute 14 which houses a continuous belt 16 upon which material is to be transported.
  • the housing 14 which is preferably formed of sheet metal, includes a rectangular cross-section and open ends to permit discharge of material at its upper or discharge end, and to permit belt tensioning at its lower or feed end, as will be described.
  • the enclosed configuration of the conveyor housing 14 ensures that dust and spillage is kept to a minimum, a known problem with some existing conveyors.
  • a transparent window 18 exists in the top wall of the housing 14 to permit inspection of the belt 16.
  • a catchment hopper 20 Adjacent the lower or feed end of the conveyor 10 is a catchment hopper 20 having walls of a size and slope to direct material toward the belt 16 during feeding of material. Mounted at the upper end of the conveyor 10 is an outlet nozzle 22 into which material is discharged from the moving conveyor belt 16, the material then dropping by way of gravity through a flexible distribution hose 24 connected below the outlet nozzle 22.
  • the catchment hopper 20 may also include an adjuster (not shown) for shifting its longitudinal position along the housing 14 and a trap door (not shown) for removing material that is left in the bottom of the catchment hopper 20. It is to be understood that alternate means for feeding and discharging from the conveyor 10 may equally well be used.
  • the belt 16 extends within and along the elongated housing 14 and is maintained and supported in the position shown in Figure 2 by a belt support floor 28 together with an assortment of rollers.
  • the primary rollers used to tension the belt are the drive roller 30 mounted within the discharge end of the conveyor 10, as shown in the enlarged view of Figure 3, and the belt tension roller 32 mounted within the feed end of the conveyor 10, as shown in the enlarged view of Figure 4.
  • Both the drive roller 30 and belt tension roller 32 are rotatable about their respective shafts 34 and 36 which are each secured between the side walls of the housing 14 in a transverse configuration.
  • a series of rotatable belt idle rollers 38 are also located below the belt 16 to both guide and tension the belt 16 during operation.
  • the drive roller 30 is rubber coated.
  • the drive roller 30, which causes the belt 16 to move when it rotates, is driven by a motor 40 mounted on the upper face of the discharge end of the conveyor 10 by a bracket 41. Coupling of the motor drive shaft 42 and the drive roller shaft 34 is achieved via a continuous drive belt 44 extending between two pulleys 46 and 48 associated with the drive roller shaft 34 and motor 40 respectively. Thus, the speed at which the belt 16 moves is dependant upon the speed at which the motor drive shaft 42 rotates.
  • the illustrated motor 40 is of the hydraulic type whereby a hydraulic pump (not shown) is used to pump hydraulic fluid, in this case oil, to the hydraulic motor 40 via a hydraulic control valve 50 through hose 52.
  • the hydraulic control valve 50 is mounted toward the lower end of the conveyor 10 and includes manual means in the form of a valve handle 54 to control the amount of fluid which is pumped to the motor 40.
  • the conveyor belt speed is controlled through control valve 50.
  • the means for driving the drive belt 30 need not necessarily be hydraulic.
  • the hydraulic motor 40 could well be replaced by a single or three phase electric motor (not shown).
  • the conveyor belt and rollers may be required to be repaired or replaced at particular times during the life of the conveyor 10, or at particular times the belt 16 may simply require tensioning.
  • the conveyor 10 of the present invention allows for both tensioning and de-tensioning of the belt 16 in such circumstances because the belt tension roller 32 is both moveable and fixable along the longitudinal axis of the housing 14.
  • the housing 14 includes a longitudinal track 56 which extends a short distance from the lower end of the housing 14 along its side walls, and allows for such movement in that the belt tension roller shaft 36 extends within the track 56 and hence may be moved therealong.
  • bracket 56 connected to the belt tension roller shaft 36 is a first bracket 56 and fixedly mounted to the outside of the housing 14 adjacent the belt tension roller 32 is a second bracket 58.
  • a threaded bolt 60 which is fixedly attached to the first bracket 56 and which extends through the fixed second bracket 58.
  • two nuts 62 and 64 are used to secure the bolt 60 to the second bracket 58 and are configured such that tightening of nut 62 causes the belt tension roller 32 to move away from the drive roller 30 thereby tensioning the belt 16, and tightening of nut 64 causes the belt tension roller 32 to move toward the drive roller 30 thereby de-tensioning the belt 16.
  • alternate means for moving bracket 56 toward and away from bracket 58 may be used.
  • a problem associated with existing agricultural conveyors is the susceptibility for material to become wedged and damaged between the moving conveyor belt and the sides of the conveyor housing.
  • the belt 16 of the present invention is both cleated and bordered so as to minimise damage to the material being conveyed.
  • a plurality of spaced apart transverse cleats 66 protrude at an angle of approximately 15 degrees from the longitudinal belt 16.
  • corrugated borders 68 and 70 which extend longitudinally on either side of the cleats 66.
  • the borders 68 and 70 are illustrated clearly in Figures 5a and 5b and their purpose is to prevent material from contacting the side walls of the housing 14, the current primary cause of damage to material such as grain, seeds and fertiliser.
  • the borders 68 and 70 are corrugated so that they are able to stretch at the position where the belt 16 circles the rollers 30 and 32. The stretched nature of the corrugated borders 68 and 70 when circling the drive roller 30 can be seen in Figure 3.
  • the belt 16 is manufactured of polyvinylchloride (PVC) or other material having similar properties, and the cleats 66 and borders 68 and 70 are appropriately bonded or fused thereto.
  • PVC polyvinylchloride
  • the conveyor 10 includes an enclosed housing 14 minimising dust and spillage, as well as a non-complex system for tensioning and de-tensioning the conveyor belt 16. Further, the belt 16 of the conveyor includes both cleats 66 and corrugated borders 68 and 70 which aid in transporting material more gently than hitherto known conveyors.
  • FIG. 6 illustrates one such use, that is, where the conveyor 10 is mounted to a mounting bracket 12 of a grain cart 72. Since grain carts of this sort are well known, its features are not described in any detail. In this situation, piles of grain 74 are fed into the catchment hopper 20 of the conveyor 10 to be discharged into the grain cart 72 through the flexible distributing hose 24 which extends into a grain cart access hatch
  • the conveyor 10 of the present invention may supersede many conveyors and augers which are used today in the agricultural industry.

Abstract

Le transporteur de grains et d’engrais (10) de la présente invention transporte de la matière particulaire de façon rapide et efficace tout en réduisant le dommage causé à la matière (75) transportée. Le transporteur comprend un boîtier allongé (14) qui renferme une bande transporteuse (16) adaptée pour recevoir la matière par l’intermédiaire d’une trémie de réception au niveau d’une extrémité inférieure du boîtier et pour transporter la matière vers l’extrémité supérieure du boîtier pour une décharge à partir de celle-ci. La bande transporteuse (16) est à la fois à tasseaux (66) et bordée (68, 70) ce qui permet que de plus grands volumes de matière soient transportés sans être en contact avec les parois latérales du boîtier (14) et ainsi de réduire le dommage causé à la matière. En outre, le transporteur (10) comprend un mécanisme non complexe destiné à tendre et détendre la bande (16). Il est prévu que le transporteur (10) de cette invention peut remplacer de nombreux transporteurs et des tarières qui sont utilisés aujourd’hui dans l’industrie agricole.
