Definitions
- the field to which the disclosure generally relates is harvesting machines, and more particularly to draper belts having improved durability and extended service life.
- Agricultural harvesting machines such as combine harvesters are used to reap, thresh, and winnow grain crops such as wheat, rye, barley, corn, soybeans, oats, flax, sunflower, and canola. More specifically, combine harvesters are used to cut grain crops at the base, separate the grains from the remainder of the plant (the chaff), and sort the grain from the chaff.
- combine harvesters are used to cut grain crops at the base, separate the grains from the remainder of the plant (the chaff), and sort the grain from the chaff.
- These machines require special adaptations to accommodate specific crops, navigate through field landscapes, and resist damage from the crops, stone, and the elements; especially moisture and high temperature which can lead to the degradation of the machine's rubber components.
- Generally harvesting machines gather crops using a header having crop dividers which define crop gathering gaps as the machine moves through a field.
- the gathered crops are pushed by a reel into a cutter bar, which runs the length of the header and is equipped with teeth made of metal or plastic to cut crops at their base.
- Headers may have a rigid or flexible header platform depending upon the operational needs and the crop being harvested.
- Flexible header platforms or "flex headers” have a cutter bar which is capable of flexing over uneven terrain. Machines using flex headers are most often used to cut soybeans, whereas conventional header platforms have a rigid cutter bar and are most often used to cut cereal crops. Freshly cut crops fall behind the cutter bar and onto a plurality of side by side draper belts which are wrapped around parallel spaced rollers.
- Draper belts function primarily to consolidate crops and move the crops from the header towards the threshing drum. Crops are fed into the threshing drum by spinning augurs. Inside the threshing drum, the grains are shaken from the plant. Grains fall through sieves into a grain collecting tank, and the plant waste, or chaff, is moved to the back of the machine by conveyor belts for later disposal.
- Draper belts are an important component of agricultural harvesters.
- Draper belts are typically called upon to operate for long periods of time and over a service life of many years. For these reasons it is necessary that draper belts be specially adapted to maximize durability and service life, and it is desirable for such adaptations to be cost effective.
- Some embodiments of the disclosure are directed to a specially adapted draper belt which offers improved durability and an extended service life.
- the draper belts are resistant to ripping and tearing; and unlike belts of the prior art, the draper belts of this disclosure are also resistant to buckling from tracking force.
- the draper belt edges of the disclosure are made using high modulus material having a modulus at least three times higher than the modulus of the material used in making the center section of the belt.
- the belt edge sections of these belts are constructed to be much stiffer than the center of the belt. This makes the draper belt according to the disclosure both durable and cost effective.
- embodiments are directed to a draper belt having a carry layer, a pulley cover layer, and a reinforcing layer which is situated between the carry layer and the pulley cover layer.
- the carry layer includes a plurality of cleats, wherein the cleats are reinforced with reinforcing rods.
- the draper belt has a first edge section and a second edge section which can be comprised of a monofilament fabric or chord fabric to increase edge stiffness.
- Some embodiment are draper belts having a carry layer, a pulley cover layer, and a reinforcing layer which is situated between the carry layer and the pulley cover layer, wherein the carry layer includes a plurality of cleats, wherein the cleats are reinforced with reinforcing rods, wherein the draper belt has a first edge section, a second edge, and center edge section located between the first edge section and the second edge section, wherein the first edge section and the second edge section of the draper belt each have a modulus that is at least three times greater than the modulus of the center section.
- Figure 1 shows a general cross-sectional view of a conventional agricultural harvesting machine
- Figure 2 illustrates a section of a conventional agricultural harvesting machine, in a perspective view
- Figure 3 depicts a draper belt, in a perspective view
- Figure 4 shows a portion of one embodiment of a draper belt according to the disclosure, in a perspective view
- Figure 5 illustrates a portion of an embodiment of a draper belt according to the disclosure, in a perspective view.
- any references to "one embodiment” or “an embodiment” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment.
- the appearances of the phrase “in one embodiment” in various places in the specification are not necessarily referring to the same embodiment.
- FIG. 1 depicts a conventional harvesting machine 19 having a reel 1 , a cutter bar 4, a threshing drum 2, and a grain elevator 3.
- the reel 1 functions to move crops into the cutter bar 4 which cuts the crops at their base using metal or plastic teeth. Cut crops fall upon a plurality of side by side draper belts which consolidate the crops and move them towards the threshing drum 2.
- the threshing drum 2 beats and breaks the crops to shake the grains 5 from the remainder of the plant, also known as the chaff 6.
- the grains 5 are collected inside a grain collecting tank. When the grain collecting tank is full, operators dispose of the chaff 6 through the back of the machine 19, and grains 5 are moved from the grain tank at a grain elevator 3.
- Figure 2 shows a section of a conventional harvesting machine having a reel 9, a threshing drum 10, a cutter bar 1 1 , and a draper belt 8 having cleats 7 located on carry layer 14.
- the carry 14 layer can be chosen from a wide variety of rubbery polymers having a desired combination of physical properties and chemical resistance.
- Figures 3, 4 and 5 depict a draper belt 8 having a carry layer 14, a pulley cover layer 13, and a reinforcing layer 12 located between the carry layer 14 and the pulley cover layer 13.
- the carry layer 14 includes a plurality of cleats 7 which are reinforced with reinforcing rods 15.
- FIGS 4 and 5 each show one embodiment of the draper belt according to the disclosure.
- the draper belt has a first edge section 16 and a second edge section 17 which are each between 3 inches (76.2 mm) and 12 inches (304.8 mm) wide, and a center section 18 located between the first edge section 16 and the section edge section 17.
- the draper belt edge sections 16, 17 are each between 4 inches (101 .6 mm) and 8 inches (203.2 mm) wide.
- Draper belts typically have a total width (sum of the width of the first edge section, the center section, and the second edge section) which is within the range of 30 inches (762 mm) to 80 inches (2,032 mm) wide.
- the draper belts of this disclosure frequently are of a width which is within the range of 50 inches (1 .2 meters) to 500 inches (12.7 meters) and typically weigh between 15 pounds (6.80 kg) and 80 pounds (36.29 kg) depending upon the harvester and the function of the belt in conjunction with the harvester header.
- the first edge section and the second edge section each have a width which is within the range of 5% to 16% of the total width of the draper belt.
- the first edge section and the second edge section each have a width which is within the range of 8% to 14% of the total width of the draper belt.
- the first edge section and the second edge section each have a width which is within the range of 10% to 12% of the total width of the draper belt.
- Each draper belt edge section 16, 17 includes a high modulus stiff reinforcing fabric.
- the reinforcing fabric can be comprised of a conventional tire cord.
- Tire cord is known to be very dimensionally stable and it is especially effective over a wide temperature range in comparison to other cords.
- the tire cord can be comprised of polyethylene terephthalate (commonly known as PET, or PETE) which typically has an intrinsic viscosity which is within the range of 0.60 dl/g and 1 .0 dl/g.
- Tire cord can also be made using polyethylene naphthalate (commonly known as PEN).
- the fabric utilized in the belt of this disclosure can include polyester or nylon fibers or a combination of both.
- the reinforcing fabric is typically treated in a resorcinol formaldehyde latex (RFL) dip to enhance adhesion between the rubber in the belt and the fabric.
- RFL resorcinol formaldehyde latex
- the latex used in the RFL dip is typically a vinylpyridine latex.
- the fabric used in the draper belt can include optionally be an aramid fabric.
- belt edge sections 16, 17 have a modulus that is at least three times greater than the modulus of the center section. In one embodiment of this disclosure, this is achieved by including a reinforcing fabric in the edge sections of the belt having a modulus which is much higher than the modulus of the reinforcing fabric used in the center section of the draper belt.
- the fabric used in the edge sections can be made with cords or filaments of a higher denier or with a material which inherently has a higher modulus or a combination of both.
- the fabric in the center section of the draper belt can be comprised of PET with the edge sections of the belt including fabric with is comprised of PEN or an aramid.
- the fabric reinforcement in the edge sections of the belt is of approximately the same as the thickness of the fabric reinforcement in the center section of the belt as depicted in Figure 4.
- the high modulus of the edge sections 16, 17 is achieved by using at least three times more fabric reinforcement in the first edge section and the second edge section of the belt than is used in the fabric reinforcement layer 12 found in the center section 18 of the draper belt 8. As depicted in Figure 5, the additional fabric reinforcements extend under the carry layer 14 and over the pulley cover layer 13 of the conveyor belt 8.
- the draper belt edge sections 16, 17 have a modulus that is at least four times greater than the modulus of the center section. In a still another embodiment, the draper belt edge sections 16, 17 have a modulus that is at least five times greater than the modulus of the center section.
- the edge sections 16, 17 have a narrowed pulley cover layer 13 and a narrowed carry layer 14 to accommodate the larger reinforcing layer 12.
- the pulley cover layer and the carry layer are thinned in the edge sections of the belt than they are in the center section of the belt.
- the draper belt 8 of the disclosure is resistant to tearing, it effectively prevents debris from proceeding through the sides of the belt, and it prevents the belt from buckling in the event of misalignment or other belt damage known to cause buckling in conventional belts.
