Definitions

  • the present technology relates to draper belts.
  • Combine harvesters have a header including a cutter bar and one or more wide-aspect conveyor belts, known generally in the art as draper belts, for moving grain crops that have been cut by the cutter bar toward the threshing drum.
  • draper belts have a conveyor surface including cleats that project from the conveyor surface and extend widthwise across each draper belt.
  • the draper belts are important components of combine harvesters. They are subjected to wear caused by, amongst other things, friction from the moving machinery and crops.
  • the cleats that project from the draper belt are notably prone to premature wear as they convey the grain crops on the conveyor surface and get hit by plant debris, stone, etc. Under certain circumstances, damaged cleats lead to less efficient conveying of the grain crops and may cause the premature failure of the entire draper belt.
  • a draper belt including a belt body having a carcass, and a top cover disposed on the carcass.
  • the top cover defines a conveyor surface.
  • the belt body further has a first side, a second side, and a width defined between the first and second sides of the belt body.
  • the draper belt further has a plurality of cleats projecting from the conveyor surface of the top cover. The cleats are spaced apart from one another lengthwise along the conveyor surface.
  • Each cleat extends across substantially all of the width of the belt body, and has a first side portion adjacent the first side of the belt body, a second side portion adjacent the second side of the belt body, a center portion extending between the first and second side portions, a leading sidewall, and a trailing sidewall.
  • the draper belt further has reinforcement fabric located on at least one of the first side portion, the second side portion and the center portion of each cleat. The reinforcement fabric covers and conforms to the leading and trailing sidewalls of each cleat.
  • the reinforcement fabric may improve the durability of the cleat as the reinforcement fabric is made of a more wear-resistant material than the cleat itself. As a result, abrasion and removal of the cleat material may be reduced compared to other draper belts. Furthermore, since the reinforcement fabric covers and conforms to the leading and trailing sidewalls of the cleat, i.e. the reinforcement fabric conforms to at least some parts of the surface of the cleat, little or no changes to the geometry of the cleat are required. Moreover, the reinforcement fabric need only be located only on portions of the cleat that are believed will be more prone to wear, whether these portions include the first side portion, the second side portion or the center portion, or any combinations thereof.
  • the reinforcement fabric is located on the first and second side portions of each cleat. Depending on the application, having the reinforcement fabric located on the first and second side portions of each cleat may limit the amount of reinforcement fabric required to improve the durability of the draper belt while permitting reversible mounting of the draper belt on the pulleys and/or drums on which it is destined to be used.
  • the reinforcement fabric includes polyester tire cord, cord fabric, or monofilament fabric. These materials have, under certain circumstances, higher toughness and wear resistance than the material from which the cleats could be made of.
  • the reinforcement fabric covers and conforms to both the leading and trailing sidewalls of each cleat.
  • having a single band or strip of reinforcement fabric covering and conforming to both the leading and trailing sidewalls of each cleat may reduce the possibilities of the reinforcement fabric debonding from the leading and trailing sidewalls.
  • a gap is defined on the conveyor surface between the reinforcement fabric covering and conforming to adjacent cleats.
  • the reinforcement fabric has warp fibers, and the reinforcement fabric is disposed such that the warp fibers extend parallel to the first and second sides of the belt body. In some applications, such an orientation of the reinforcement fabric may improve its toughness and resistance to wear.
  • the reinforcement fabric is one of a plurality of layers of reinforcement fabric covering and conforming to the leading and trailing sidewalls of each cleat. In some applications, having a plurality of layers of reinforcement fabric may assist in improving the durability of the cleat and/or may permit repairing a worn-out cleat by adding one or more layers of reinforcement fabric thereon, which may further improve the life of the draper belt.
  • the draper belt further includes an embedded reinforcement fabric disposed within the cleat and extending between the leading and trailing sidewalls.
  • the embedded reinforcement fabric conforms to the leading and trailing sidewalls. Under certain conditions, having an embedded reinforcement fabric may further assist in improving the durability of the cleat.
  • each cleat has a top wall extending between the leading and trailing sidewalls, and the reinforcement fabric covers and conforms to the top wall of each cleat.
  • the plurality of cleats is formed integrally with the top cover.
  • the draper belt further includes a reinforcing rod embedded within each cleat.
  • the reinforcing rod is disposed between the leading and trailing sidewall and extends across substantially all of the width of belt body.
  • the reinforcing rod may improve the structural rigidity of the cleat.
  • each cleat has a first end wall being adjacent the first side of the belt body, an opposed second end wall being adjacent the second side of the belt body, and the first and second end walls are substantially free of the reinforcement fabric.
  • having the first and second end walls substantially free of the reinforcement fabric may reduce the possibilities of the reinforcement fabric debonding from the leading and trailing sidewalls.
  • a draper belt including a belt body having a carcass, and a top cover disposed on the carcass.
  • the top cover defines a conveyor surface.
  • the belt body further has a first side, a second side, and a width defined between the first and second sides of the belt body.
  • the draper belt further has a plurality of cleats projecting from the conveyor surface of the top cover. The cleats are spaced apart from one another lengthwise along the conveyor surface. Each cleat extends across substantially all of the width of the belt body, and has a leading sidewall and a trailing sidewall.
  • the draper belt further has reinforcement fabric embedded within each cleat and extending between the leading and trailing sidewalls.
  • the reinforcement fabric conforms to the leading and trailing sidewalls of each cleat.

  • the carcass 24 and the top cover 30 may be constructed of a wide variety of materials and structures including metallic and elastomeric components known in conveyor systems. As the specific properties and materials of the carcass 24 and top cover 30 are not central to the present technology, they will not be described in detail.
  • the belt body 22 has left and right sides 40, 42.
  • a width 44 is defined between the left and right sides 40, 42.
  • the width 44 of the belt body is of about 101.6 cm (40 inches), but the width 44 could differ in other implementations.
  • the belt body 22 further has left and right side edges 46, 48. The thickness of the belt body 22 is greater in the left and right side edges 46, 48 than in the region extending therebetween.

  • Each cleat 60 extends perpendicular to a forward travel direction F of the draper belt 20a, but it is contemplated that the cleats 60 could extend in a skewed fashion across the belt body 22 in other implementations.
  • cleats 60 are illustrated, namely 60r, 60i, 60f.
  • the cleat 60f is located forward of the cleat 60i, and the cleat 60r is located rearward of the cleat 60i when the draper belt 20a moves in the forward travel direction F.
  • the cleats 60r, 60i, 60f have the same shape, dimensions and structure, but it is contemplated that the cleats 60r, 60i, 60f could differ from one another in other implementations.
