    PLANT EQUIPMENT AND CUTTER
    SCOPE OF THE INVENTION
    The invention relates to the field of combine harvesters, and more particularly to crop elevators used in such harvesters.
    BACKGROUND OF THE INVENTION
    This invention relates to the field of combine harvesters as they are applied, for example, to crops to be harvested such as grain or the like. Such a harvesting machine usually comprises a header for harvesting a crop and a transport system for transporting the harvested crop to a tank aboard the harvesting machine or to a grain cart or truck moving together with the harvesting machine. Such a transport system may, for example, comprise an elevator with a lower inlet section for receiving a stream of harvested crop and an upper outlet section for unloading the stream of harvested crop. Typically, a yield detector (sensor) is disposed near the outlet section, the yield detector being used to indicate the amount of crop harvested. In principle, such a sensor can be calibrated by comparing the amount of harvested crop as measured by comparing the sensor with the effective amount of harvested crop, e.g. obtained by weighing the amount of harvested crop with a scale. In practice, however, such an approach may be too cumbersome, for example, in the case where several harvesting machines harvested crop is supplied to a common grain cart or truck. It is therefore an object of this invention to provide an alternative way to calibrate a yield detector of a combine.
    BE2017 / 5398
    SUMMARY OF THE INVENTION
    It would be desirable to have a combine that is able to more accurately determine a yield of the harvested crop. To better address this issue, in a first aspect of the invention, a crop elevator is provided for a harvesting machine, comprising:
    - a rising section and a falling section;
    - a housing enclosing the rising section and the falling section;
    - an elevator loop arranged inside the housing and consisting of a series of blades to raise a harvested crop;
    - a weighing system configured to determine a weight of the harvested crop present on a measuring vane of the series of blades during a rising movement of the measuring vane in the rising section, the weighing system consisting of a weight sensor which is mechanically coupled to the measuring vane and configured to give a weight signal representative of the weight of the harvested crop;
    wherein the rising section includes a measuring section, wherein the weighing system is configured to determine the weight signal when the measuring vane is in the measuring section of the rising section, and wherein a friction between the measuring vane and the housing in the measuring section is lower than a friction between the measuring vane and the housing outside the measuring section during the rising movement of the measuring vane in the rising section.
    In accordance with this invention, a crop elevator is provided to raise a stream of harvested crop. The crop elevator consists of an elevator loop that is equipped with a series of blades that move through a rising and falling section of the elevator. In addition, the rising section and the falling section are enclosed by a house.
    BE2017 / 5398
    In one embodiment, the crop elevator according to the present invention has an inlet section disposed near a bottom portion of the elevator loop and configured to receive a stream of harvested crop, and an outlet section disposed near an upper portion of the elevator loop and is configured to unload the crop harvested. In such an embodiment, the stream of harvested crop that is received by the inlet section is distributed over the vanes and transported up through the rising section.
    In accordance with this invention, the crop elevator further comprises a weighing system for weighing the amount of crop harvested on the blades. Such a weighing system may, for example, comprise one or more weighing sensors configured to give a weight signal representative of the weight of the harvested crop lying on one or more vanes, here called measuring vane or measuring vanes, during upward transport. Here it is assumed that weighing sensors for weighing the harvested crop in crop elevators are known. Known arrangements, however, are known to provide no reliable measurement results due to the presence of friction between the measuring vane or vanes and the elevator, i.e. the inner surface of the housing portion that surrounds the rising section. In this respect it can be noted that, in order to avoid spillage of the harvested crop along the blades, only a narrow gap can be allowed between the blades and the housing. As a result, the blades can occasionally make contact with the housing of the elevator, which is unfavorable for the reliability of the weighing results. To mitigate this effect, the crop elevator according to the present invention is equipped with a measuring section, the measuring section being part or part of the rising section of the elevator, the weighing system being configured to record the weight signal of the one or more weight sensors. ask when the one or more measuring vanes
    BE2017 / 5398 are located in the measuring section of the elevator. Furthermore, in accordance with this invention, friction-reducing measures are taken to ensure that a friction between a measuring vane or measuring vanes and the housing in the measuring section is lower than a friction between the measuring vane or measuring vanes and the housing outside the measuring section. As a result, a passage of the one or more measuring vanes through the measuring section can proceed with a reduced friction, compared to a passage of the measuring vane or measuring vanes through the rest of the rising section. As a result, a more accurate and reliable weighing of the harvested crop on the measuring vane or vanes can be achieved.
    In one embodiment of the present invention, a cross section of the measurement section is larger than a nominal cross section of the rising section. As a result, contact between the blades and the housing of the elevator during weighing can be avoided. Since this enlarged cross-section is only arranged in the measuring section of the elevator, the spillage of the harvested crop through the gap between the blades and the housing will remain relatively limited, so that the efficiency of the lifting process is not affected.
    Alternatively or additionally, other friction-limiting measures may be taken to ensure a more accurate weight measurement. Such measures may be, for example, the use of a specific coating, e.g., a coating with a low coefficient of friction such as polytetrafluoroethylene (PTFE), in the measurement section, or the use of a bearing between the housing and one or more blades in the measurement section. By way of example, an air bearing may be provided between the housing in the measuring section and a facing surface of the measuring vane or blades, to ensure that there is no contact between the housing and the measuring vane or blades during weighing.
    BE2017 / 5398
    As yet another example of a friction-limiting measure, a thinner housing or a housing made of a different material can be used in the measuring section, so that greater flexibility is obtained from the part of the housing that encloses the measuring section and / or a larger gap between the house and the blades that pass through it.
    In accordance with this invention, the weighing system includes one or more weight sensors to generate a weight signal representative of the weight of the harvested crop. As a first example of such sensors, the one or more vanes used for weighing may, for example, be equipped with force or pressure sensors, e.g. load cells, mounted on, or built into, an upper surface of the vanes.
    As a second example, tension meters, e.g. mounted on the belt or chain to which the blades are connected, can be used to determine the weight of the one or more blades and the harvested crop resting on it.
    In one embodiment, the one or more weight signals from the one or more weight sensors may be supplied to a processor of the weighing system, the processor being configured to receive the weight signal or weight signals and determine the weight of the harvested crop, based on the received weight signal or signals.
    In one embodiment, the weighing system further comprises an approach sensor configured to provide an approach signal representative of a position of the measuring vane or vanes. Such an approach sensor may, for example, be an inductive or capacitive sensor that is mounted on a bottom of the measurement section. Thus, the proximity sensor can be used to detect the arrival of the measuring vane or
    BE2017 / 5398 vanes in the measuring section, and thus to indicate when the weight signal or weight signals must be processed.
    In one embodiment, the crop elevator according to the present invention can be used in a combine according to the present invention. Such a harvesting machine can for instance be equipped with a yield detector which is configured to give a yield signal which is representative of a stream of harvested crop that is discharged by the crop elevator. In such an embodiment, the weight of the harvested crop on the measuring vane or vanes determined by the weighing system can be used to calibrate the yield detector.
    These and other aspects of the invention will be more readily appreciated if the invention is better understood by referring to the following detailed description and when considered together with the accompanying drawings in which like reference symbols indicate like parts.

    DETAILED DESCRIPTION OF EMBODIMENTS
    BE2017 / 5398
    Figure 1 represents a cross-section of a crop elevator 100 as known in the art. The crop elevator 100 includes an elevator loop mounted within a housing 110 of the crop elevator 100, the elevator loop consisting of a series of blades 120 mounted on a chain or belt 130 of the elevator loop. By driving the elevator loop as indicated by the arrows 140, the vanes on the left-hand side, as seen in the view of Figure 1, will move up the chain or belt 130 while the vanes on the right-hand side of the chain or belt 130 move down. The portion of the crop elevator where the blades move upward is further referred to as the rising section 150 of the elevator 100, while the portion of the crop elevator where the blades move downward is further called the falling section 160 of the elevator 100. The crop elevator 100 as shown further includes an inlet section 170 configured to receive a stream of harvested crop 180, e.g., grain, wherein the crop stream 180 is received by the vanes 120 and transported up in the ascending section. In the arrangement shown, the stream of harvested crop 180 is supplied to the inlet section 170 by means of a jack 190, the jack 190 extending in the Y direction, perpendicular to the XZ plane of the drawing. The crop elevator 100 as shown further includes an outlet section 195 for releasing the stream of harvested crop 180 at a higher level. The provision in such an elevator of a weighing system (not shown) is known to determine the amount of harvested crop on the blades in the rising section. However, by applying a relatively small gap between the vanes 120 and the housing 110, it is possible that the weighing results obtained in such an arrangement are not accurate.
    To improve the measurement accuracy of the weighing process, a modified crop elevator is therefore proposed. Figure 2 shows schematically
    BE2017 / 5398 a crop elevator 200 according to a first embodiment of the present invention. The crop elevator 200 includes an elevator loop disposed within a housing 210 of the crop elevator 200, the elevator loop including a series of blades 220 mounted on a chain or belt 230 of the elevator loop. By driving the elevator loop as indicated by the arrows 240, the blades on the left side of the chain or belt 130 will move up into the rising section 250 of the elevator, while the blades on the right side of the chain or belt 130 will move down moving in the descending section 260 of the elevator 20. In the illustrated embodiment, the crop elevator 200 as shown further includes an inlet section 270 configured to receive a stream of harvested crop 280, e.g., grain, where the crop stream 280 is received by the blades 220 and is transported upwards in the rising section. In the illustrated embodiment, the stream of harvested crop 280 is supplied to the inlet section 270 by means of a jack 290, the jack 290 extending in the Y direction, perpendicular to the XZ plane of the drawing. The crop elevator 200 as shown further includes an outlet section 295 for releasing the stream of harvested crop 280 at a higher level. In accordance with this invention, the crop elevator 200 further includes a weighing system configured to determine a weight of harvested crop 280 that is on at least one of the vanes 220 during an ascending movement of the at least one of the vanes in the ascending section. In the illustrated embodiment, the weighing system includes a weight sensor 300 that is configured to output a weight signal representative of the weight of the harvested crop being transported through one or more of the blades. Such a weight sensor 300 may, for example, contain a weighing cell mounted on or built into an upper surface of a vane of the vane series 220. Furthermore, the weighing system is configured in accordance with this invention to carry out the weighing process
    BE2017 / 5398 when the paddle or paddles to be weighed are in a specific section of the ascending section of the elevator, this specific section being called the measuring section 255 of the elevator 200. In accordance with the present invention, the measuring section 255 as used in the crop elevator is configured such that a friction between a vane passing through the measuring section where this vane is called a measuring vane, and the housing is lower than a friction between the measuring vane and the vane housing outside the measuring section, ie between the measuring vane and the housing when the measuring vane moves upwards in the rising section outside the measuring section. In accordance with this invention, various friction-limiting measures may be taken to allow passage with reduced friction of the measuring vane or vanes through the measuring section 255 of the rising section 250.
    In the illustrated embodiment, a cross-section of the housing enclosing the measuring section is larger than a nominal cross-section of the housing enclosing the rising section. As can be seen, the width W of the rising section at the level of the measuring section 255 is enlarged relative to a nominal width Wn of the rising section outside the measuring section. The same widening or widening can also be applied in the Y direction. As a result, a measuring vane arriving in the measuring section 255 will no longer make contact with the housing 210 due to the enlarged cross-section. This will enable the weighing system to weigh the blade or blades to be weighed more accurately.
    In the embodiment shown, the height Zm of the measuring section and the distance between two successive vanes of the vanes 220 are such that only one measuring vane will be at the same time as the measuring section. However, by increasing the height Zm of the measurement section, more than one blade can be located in the measurement section, i.e. more than one measurement blade, e.g. two or three. When each measuring vane is equipped with a
    BE2017 / 5398 sensor or, as will be explained in more detail below, if a pair of voltage meters is used, the total weight of the measuring vanes can be determined.
    In the illustrated embodiment, the weighing system further comprises a processing system 310 which is configured to receive, on an input terminal 312, the weight signal of the one or more weight sensors 300 and which is configured to determine the weight of the harvested crop based on the received weight signal. Such a processing system 310 may be embodied, for example, as a microprocessor, a microcontroller, a computer, or the like. In one embodiment, the determined weight and / or the received weight signals can e.g. be stored in a memory unit of the processing unit. In the illustrated embodiment, the processing unit 310 further comprises an output terminal 314 on which a signal is available which is representative of the determined weight.
    In the illustrated embodiment, it can be seen that the housing portion of the measuring section 255 includes a lower portion 212 with a width that increases from the nominal width Wn to the enlarged width W and an upper portion 214 with a width that decreases from the enlarged width . As will be appreciated, alternative ways of providing an enlarged cross-section in a specific section of a housing may also be considered.
    In the illustrated embodiment, the crop elevator 200 has an outlet section 295 for releasing the stream of harvested crop 280 at an elevated level. The crop elevator 200 further includes a yield detector 296, which is configured to output a yield signal representative of the crop flow discharged through the outlet section 295. Such yield detector may e.g. be a yield detector as known
    BE2017 / 5398 according to the prior art. Usually a calibration of a yield detector is needed to ensure an accurate match between the amount of crop harvested as determined on the basis of measurements made by the yield detector and a measurement of the amount of harvested crop with a scale on the farm where the harvested crop is collected .
    In one embodiment of the present invention, a yield detector 296 as used in a crop elevator can be calibrated based on the weight signal of the weighing system, e.g., a weight signal obtained from the weight sensor 300.
    Figure 3 schematically shows a more detailed cross-sectional view of a measuring section 455 of a crop elevator according to the present invention. Figure 3 shows schematically a part of an elevator loop 430, wherein the movement of the elevator loop 430 is indicated by the arrows 435, and a measuring vane 420, on which a quantity of harvested crop 480 is present, which is connected to the elevator loop 430. Figure 3 shows furthermore schematically a part of the housing 410 of the crop elevator. As can be seen, the width Wn of the housing in the illustrated embodiment increases to an increased width W in the measurement section 455. Due to the increased width of the housing, a gap δ is created between the measuring vane 420 and the housing 410 In the illustrated embodiment, the gap is at its largest at the lower end of the measurement section 455 and gradually decreases upwards in the measurement section until it becomes essentially zero. By providing the gap δ between the measuring vane 420 and the housing 410, the friction between the measuring vane 420 and the housing 410 is reduced, at least as long as the measuring vane 420 is located within the measuring section 455. Thus, this passage through the measurement section 455, in accordance with this invention, is used to determine the weight of the amount of crop 480 harvested on the
    BE2017 / 5398 measuring vane 420. To weigh the amount of crop on the measuring vane 420, the measuring vane 420 can be equipped with a weighing cell or a pressure sensor 490, such weighing cell or pressure sensor thus being an example of a weight sensor that can be used in a weighing system of the crop elevator according to the present invention. As an alternative to using a load cell mounted on or built into a surface of the measuring vane 420, a pair of tension meters 492 can be used to determine the weight of the harvested crop 280 on the measuring vane 420. As can be seen, one tension meter is one 492 of the pair of tension meters 492 arranged on the elevator loop 430 above the vane 420 while the other tension meter 492 of the pair of tension meters 492 is arranged below the vane. The difference between the voltage measured by the sensor 492 can be considered as a measure of the weight of the elevator section between the sensors, plus the weight of the blade, plus the weight of the harvested crop 480. By means of a factory calibration the weight of the elevator section between the sensors, plus the weight of the blade 420, can be determined in advance, and used to calculate the weight of the harvested crop 480 that is located on the blade 420. Alternatively or additionally, the weight of the elevator section between the sensors, plus the weight of the vane 420, can also be determined during operation, more particularly when the vane 420 and the sensors 492 move downward in the descending section of the elevator. Note that in the descending section, the relative position in the vertical direction of the sensors is reversed. In such an arrangement, ie where the weight of the elevator section between the sensors plus the weight of the vane 420 are determined during operation, it may be worthwhile to also have a measuring section in the descending section, since the passage of the vanes through the falling section may also suffer from friction.
    BE2017 / 5398
    Figure 3 further shows schematically an approach sensor 494 which is mounted on the housing 410 below the measuring section 455. Such sensor 494, e.g., a capacitive, inductive, or optical sensor, may generate a signal indicating the presence of the measuring vane 420. Thus, in the illustrated embodiment, such a signal may indicate that the measuring vane 420 is about to be on. to arrive in the measurement section 455 and that the weight measurement can start.
    In the embodiment shown, the measuring section 455, more particularly the part of the housing of the measuring sector, is wider than a part of the housing below or above the measuring section. As will be understood, the same or comparable widening can be applied in a direction perpendicular to the drawing, ie in the Y direction perpendicular to the XZ plane of the drawing, and thereby the friction between a vane 420 passing through the measuring section 455 further reduce.
    Figure 4 schematically shows an alternative way to reduce the friction between a measuring vane 420 and a portion 510 of the housing of a crop elevator according to the present invention. Figure 4 schematically shows, as in Figure 3, a part of an elevator loop 430, the movement of the elevator loop 430 being indicated by the arrows 435, and a measuring vane 420, on which a quantity of harvested crop 480 is present, which is connected to the elevator loop 430. Figure 4 further shows diagrammatically a part of the housing 510 of the crop elevator, wherein the part 510 of the housing has an opening with a height H corresponding to the height of the measuring section 455. In the embodiment shown, the opening is covered with a lid 520 disposed on an outer surface 510.1 of the housing. Thus, the width Wn of the housing 510 increases to an enlarged width W in the measurement section 455. In the illustrated embodiment, the width W corresponds to the width Wn + the thickness of the housing 510 in the X direction. As a consequence of the
    BE2017 / 5398 In the measuring section 455 there is a gap δ between the measuring vane 420 and the cover 520. As a result, a measuring vane 420 that moves along the measuring section 455 will experience a reduced friction.
    In one embodiment of this invention, the lid 520, as used herein, to cover the opening of the housing can be made thinner and / or made of a material that is more flexible than the material used for the housing. Thus, the friction between the measuring vane 420 and the lid 520 will be further reduced.
    In one embodiment, the portion of the housing that encloses the measurement section, rather than making an opening in the housing and covering it, can be made thinner than other parts of the housing. Thus, the friction between the vane that passes through the measuring section and the housing can also be reduced.
    The crop elevator according to this invention makes it possible to more accurately determine the amount of harvested crop being transported upwards by using a measuring section that has a reduced friction. This weighing result can be used, for example, to calibrate a yield detector that is usually mounted on or near an outlet section of the harvesting machine.
