Definitions

  • the invention relates to a method and a measuring arrangement for detecting the mass flow rate of crop, which is conveyed by means of a conveyor, comprising: a first measuring device for weighing the conveyor with the conveyed crop, a second measuring device for determining the volume of the crop conveyed by the conveyor, and a computer connected to the first measuring device and the second measuring device, which is operable to determine the mass density of the crop based on the measured values of the first measuring device and the second measuring device.
  • Measuring devices which optically detect the volume of the harvested material (DE 198 02 756 A). It should be regarded as disadvantageous that, although it is possible to detect the volume, but not the mass or weight of the material, which is much more relevant for the purposes mentioned than the volume. Recording the density of the material and converting the volume into a mass is conceivable but cumbersome and error prone due to frequent and short term changing densities of the harvested material.
  • DE 19541 167 A describes a combine harvester in which the volume of the crop in the grain elevator is optically detected. Furthermore, downstream of the grain elevator, a calibration device in the form of a container provided with a balance is provided, into which the crop is diverted when the quantity measurement is switched on, at certain time intervals, upon input of an operator or after changing the crop type. The calibration device is used to detect the mass of a quantity of the crop whose volume is also known, so that subsequently the optically detected volume of the crop can be converted into a mass based on the values of the calibrating device.
  • DE 42 00 770 A describes a measuring arrangement for determining the filling capacity of tobacco material correlating with the density.
  • the material is transported on a conveyor belt and with a laser scanner, the height of the material is detected on the conveyor belt, while on the basis of the known conveying speed, the volume of the material is determined.
  • the conveyor belt is weighed to determine the mass of the material.
  • the density is then calculated by dividing the mass by the volume to obtain information about the fillability of the material. Since the throughput is substantially constant due to the use of the measuring arrangement in a cigarette manufacturing plant, the mass values which are faulty at lower throughputs and which can result from the weighing of the conveyor belt with the material are not problematic for the described application.
  • DE 198 08 148 A which is considered to be generic, describes an arrangement for determining the mass fraction of earth in conveying streams of agricultural products, such as sugar beet or potatoes.
  • the crop is transported on a chain conveyor.
  • the volume of the crop is detected by means of a laser scanner scanning its surface, while the mass of the crop is determined by weighing the chain conveyor.
  • the density of the crop is calculated by dividing the mass by the volume, and based on a predetermined, known standard bulk density, the soil content in the crop is finally determined. Again, the problem that the mass determination is flawed at smaller throughputs, not solved.
  • the object underlying the invention is seen to provide a measuring arrangement suitable for detecting the mass flow rate of crop material which supplies sufficiently accurate measured values even at relatively low throughputs.
  • a measuring arrangement for detecting the mass flow rate of crops conveyed by means of a conveyor comprises a first measuring device, with which the conveyor is weighed together with the crop material conveyed by it.
  • a second measuring device is provided for determining the volume of the crop conveyed by the conveyor.
  • a computer device continuously calculates the mass density of the crop based on the measured values of the first measuring device and the second measuring device and stores them.
  • the computing device determines mass flow rates and uses them as output values that are based only on the current measurements of the first measurement device. This threshold may be at a certain percentage of the maximum expected mass or volume throughput, for example at 10%.
  • the computer device determines and outputs mass flow rates that are based on the current measured values of the second measuring device and the mass density of the crop, that at the last above-threshold throughput based on the measured values of the first measuring device and the second measuring device was determined.
  • the accuracy of the measuring arrangement is increased, since with smaller throughputs, in which the measured values of the first measuring device measuring the weight or mass of the conveyor are not sufficiently accurate, the substantially more accurate measured values of the second measuring device are used.
  • the latter are converted into mass throughputs with the last reliably recordable mass density of the crop.
  • the second measuring device preferably comprises a non-contact, for optical scanning of the surface of the conveyor or the crop located thereon suitable rangefinder, in particular a laser rangefinder, which scans the surface of the conveyor transversely to the conveying direction and / or in the conveying direction.
  • suitable rangefinder in particular a laser rangefinder, which scans the surface of the conveyor transversely to the conveying direction and / or in the conveying direction.
  • a conveyor for example, a belt conveyor in question.
  • the invention can also be used on other types of conveyors, for. B. to paddle elevators whose delivery volume can be optically detected, as described in DE 198 02 756 A, and their weight can be detected by weighing the whole paddle elevator to the suspension.
  • the computer device can perform a plausibility check between the measurement results of the first measuring device and the second measuring device in an example between 10% and 50% of the maximum expected throughput transition and make a warning of the operator in implausibilities or the values of the measuring device with the implausible appearing values ignore and calculate the mass flow rate based on the readings from the other meter.
  • the measuring device according to the invention is preferably used on harvesting machines, such as combine harvesters.
  • FIG. 1 is a schematic side view of a combine harvester with a conveyor for conveying the cleaned grain, which is associated with a measuring arrangement according to the invention
  • Fig. 3 is a view of the conveyor from the front
  • FIG. 4 shows a flowchart according to which the computer device of the measuring arrangement operates.
  • FIG. 1 shows a self-propelled combine harvester 10 with a support frame 12 which is supported on front, driven and rear steerable wheels 14 on the ground and is moved away from them.
  • the wheels 14 are rotated by means not shown drive means in rotation to the combine 10 z. B. to move over a field to be harvested.
  • a crop gathering device (not shown) in the form of a cutter or corn picker or the like can be connected to harvest crop from the field and up and rear by a feeder 18 having a threshing device with a transverse threshing drum 20 and one of these associated concave 22 supply.
  • a straw shaker 26 the crop is then fed to a straw shaker 26.
  • a reverse auger 44 returns unmanaged ear parts through another elevator, not shown, back into the threshing process, ie feeds them back to the threshing drum 20.
  • the chaff is ejected at the rear of the cleaner 34.
  • the cleaned grains from the grain tank 42 can be discharged through a discharge system with cross augers and a discharge conveyor 46.
  • the systems mentioned are driven by means of an internal combustion engine 48 and controlled by an operator from a driver's cab 50.
  • the various devices for threshing, conveying, cleaning and separating are located within the support frame 12.
  • the combine harvester 10 is associated with an antenna 52 for receiving signals from a satellite-based position-sensing system (eg GPS) and a computer device 54 connected to the antenna 52.
  • the computer device 54 is furthermore connected (wirelessly, eg via radio or optically or by wire, eg via a bus line) to two measuring devices 56, 58 which interact with the conveyor 38.
  • the computer device 54 together with the measuring devices 56, 58, forms a measuring arrangement for detecting the mass throughput of the crop conveyed by the conveyor 38 and records the mass throughput in a georeferenced manner.
  • the first measuring device 56 comprises a total of four force sensors in the form of strain gauges or other suitable sensors for detecting the weight of the conveyor 38.
  • the four force sensors are each between the support frame 12 and one of four bearings 60 are arranged, on which a driven shaft and a freely rotating axle 62 are supported, the rollers 64 support, around which a conveyor belt 66 rotates, at the top of which discharged from the cleaning device 32, cleaned crop is conveyed to the elevator 40.
  • the first measuring device 56 thus detects the weight of the conveyor 38.
  • it would be conceivable to associate with the first measuring device 56 means for compensating for impacts, which may be caused, for example, by unevenness in the ground and include, for example, accelerometers.
  • the second measuring device 58 is designed as the surface of the conveyor 38 transversely scanning laser rangefinder.
  • the height of the crop 68 above the conveyor belt 66 is determined on the basis of the transit time of the light emitted from the second measuring device 58 to the conveyor 38 and reflected back to the second measuring device 58. In the process, a plurality of measured values are detected over the width of the conveyor belt 66.
  • the computer device 54 (or the second measuring device 58) also receives from a speed sensor 70 information about the respective conveying speed of the conveyor 38, by continuously integrating the detected height values of the crop 68 over a revolution of the conveyor belt 66 of a detection of the weight by means of the first Measuring device 56 associated volume of the crop 68 to determine.
  • the speed sensor 70 may be a radar sensor cooperating with the lower run of the conveyor belt 66 or may detect the rotational speed of the shaft or axle 62.
  • the speed of the conveyor 38 can be fixed depending on the type of crop and / or the respective maximum throughput or regulated depending on the current throughput, so that a maximum resolution over the measuring range can be achieved, especially if you set the speed of the conveyor 38 automatically in such a way in that a sufficient occupancy of the conveyor 38 with crop 68 is always achieved, which enables a sufficiently accurate measurement with the first measuring device 36.
  • step 100 the weight detected by the first measuring device 56 is interrogated in step 102, and the speed of the conveyor belt 66 is queried by the speed sensor 70.
  • step 104 the second measuring device 58 then retrieves the height profile of the crop 68 above the conveyor belt 66 and converts it by means of the signal of the speed sensor 70 into a volumetric measurement value that can be assigned to the weight measuring value previously obtained by the first measuring device 56, as described above.
  • step 106 the mass density of the crop is calculated by dividing the mass corresponding to the weight by the volume.
  • the mass density and the associated weight force are stored in the following step 108.
  • a threshold corresponds for example to 10% of the maximum expected weight force.
  • This mass flow rate which can be converted into a yield value measured in kg / m 2 , based on the forward driving speed of the combine harvester and the cutting unit width measured by means of a sensor (not shown), is stored geo-referenced.
  • the determined mass flow rate can also be displayed to the operator and used to automatically control the propulsion speed of the combine and / or to automatically adjust parameters of the threshing and / or cleaning device.
  • the mass density can be saved.
  • step 114 follows. Since then the measured value of the first measuring device 56 is not sufficiently accurate, the more accurate measured value of the second measuring device 58 is used, which is converted by means of the last stored at reliable measured values of the first measuring device mass density in a mass flow rate (this is in detail the volume multiplied by the mass density measured in kg / m 3 and the speed of the conveyor 38 and by the in Conveying direction measured length of the crop 68 acted upon part of the conveyor belt 66 divided).
  • the mass density is used, which was determined at the last throughput above the threshold on the basis of the measured values of the first measuring device 56 and the second measuring device 58 and stored by the computer device 54.
  • the mass and velocity determined in this way are used to determine the mass flow rate.
  • This mass flow rate which can be converted into a yield value measured in kg / m 2 , based on the forward driving speed of the combine harvester and the cutting unit width measured by means of a sensor (not shown), is stored geo-referenced.
