  • Patent number: 10709066
    Abstract: A method for analyzing the composition of a grain-MOG mixture comprising a kernel fraction and an MOG-fraction. The method includes steps of receiving a grain-MOG mixture, at a thermal excitation location, subjecting a sample volume of the grain-MOG mixture to a thermal excitation using a thermal excitator, generating a thermal image at an imaging location of at least a surface of the sample volume of the grain-MOG mixture that has been subjected to the thermal excitation, processing the thermal image and therewith obtaining data representing the temperature distribution over the thermal image, and relating the temperature distribution to the share of the kernel fraction in the grain-MOG mixture. A device for analyzing the composition of a grain-MOG mixture comprising a kernel fraction and an MOG-fraction is also provided.

  • Patent number: 9949435
    Abstract: A grain tank level sensing system for a combine which harvests grain. The combine includes an upwardly open grain tank fillable with harvested grain and a cover that is displaceable for closing off the open grain tank. An actuator displaces the cover between an open and close position and either single or dual ultrasonic sensors continuously detect the level of grain in the tank and generate a signal proportional to the level of grain in the grain tank. A control system receives the signal from the ultrasonic sensors and generates an indication of the level in the tank to a monitor and/or disables the actuator to initiate the closing function when the grain tank is full.

The grain receptacle is releasably attached to the underside of the combine and may be dropped directly upon the field being harvested when the operator so desires. Once the receptacle is released upon the field, the grain and chaff are collected thereon as the combine traverses the field, whereupon the operator will then stop the combine and inspect the receptacle.

    Abstract: A monitor for measuring the moisture content of grain comprises an AC signal source for transmitting a measurement signal along a measurement signal path that includes a sensor region in which grain may, or may not, be present, and an analyzer for determining the attenuation of the measurement signal along the path, the analyzer producing an indication of the moisture content of grain in the sensor region that is dependent on the attenuation. A simulator is provided to permit calibration, testing, maintenance and/or demonstration of the monitor without the requirement of grain in the sensor region. The simulator includes a programmable attenuator that is selectively electrically inserted in the measurement signal path and a control circuit for controlling the attenuator so that the measurement signal is attenuated and the analyzer produces an indication of grain moisture content even though no grain is present in the sensor region. The attenuator may be a PIN diode or a programmable capacitor.

  • Patent number: 5509854
    Abstract: A grain harvesting combine has an elevator system for conveying tailings and clean grain. The tailings are conveyed above the grain storage bin where they enter a chute and flow back to the threshing rotor. A window located at the entrance of the chute cooperates with impellers on the threshing rotor to create a strong downdraft to facilitate flow of the tailings. A stuck crop chamber has a trap door that senses when product jams in the elevator and automatically opens to discharge crop if so.

  • Patent number: 5480354
    Abstract: An apparatus and method for on-the-go measuring of the amount and quality of grain being harvested including a first light source for projecting a first light image onto a pile of grain on a conveyor in a harvesting machine to cream a three-dimensional light image on the pile of grain on the conveyor and then converting the light image into coordinates for comparison to reference coordinates to determine the volume of the pile of grain on the conveyor belt; and an apparatus for determination of the amount of moisture in the pile of grain by projecting a second light image of a first wavelength onto the pile of grain, with the wavelength of the light of a frequency responsive to the amount of moisture in the pile of grain, and measuring the amount of reflectance of the light image of the first wavelength; and projecting a third light image of a second wavelength on the pile of grain, with the second wavelength of light in a region where reflectance is not responsive to the amount of moisture in the pile of gra

  • Patent number: 5354236
    Abstract: A cost effective and efficient method and apparatus for converting a "husk-off" corn picker into a "husk-on" corn picker to reduce kernel loss and damage. The husking bed of the "husk-off" corn picker is removed and replaced with a corn conveyor consisting of a series of driven flights which convey corn from one end of the picker to the other. The corn conveyor is set at an elevated angle so that the uptake end is lower than the deposit end of the conveyor. A suction fan is attached to the picker above the corn conveyor and sets of rubber air dams are placed around the conveyor to increase the effectiveness of the fan. An air inlet means is provided in the side of the picker so that the suction means can pull air under the corn conveyor and across the deposit end of the corn conveyor as the ears of corn fall from the conveyor. This directed air flow pulls the debris from the ears of corn as the ears fall and carry the debris into the suction means where it is blown out and away from the corn picker.

  • Patent number: 5326320
    Abstract: In a method and an apparatus for forage processing, in order to accelerate its drying process, mown stalk material is fed to rotating pressing elements (7, 7a, 7b), which consolidate the stalk material into a mat of stalk material. In order to produce an inherently stable mat of stalk material, the thickness and density of said mat are to be held constant, independent of the quantity of stalk material supplied by a mowing or collecting means (1), and the forage constituents within the mat are to be better mixed. To this end, the volume of stalk material fed to the pressing means (7) and a conveying speed of the pressing elements (7a and 7b) are continuously transmitted to a control means (20) as measured values, and on the basis of these parameters the conveying speed is reduced by means of the control means (20) in the case of a small quantity of stalk material accumulating (FIG. 1).

  • Patent number: 5083978
    Abstract: There is disclosed a root crop harvesting machine, especially a potato harvesting machine which can dig-up two rows of crop and then discharging the crop laterally of the machine to any required extent via an elevator which is adjusted to a lateral discharge mode, as shown in FIG. 1, to permit the dug-up crop to be deposited in rows for drying purposes. Once drying has been completed, the same machine can then be used to pick-up the dried crop and then, following adjustment of the elevator to an elevational position as shown in FIG. 2, the dried crop can be discharged into a collecting vehicle. The harvesting machine of the invention therefore has two discharge functions, and can replace two existing pieces of equipment. The invention also enables novel methods of crop harvesting to be carried out.

  • Patent number: 4959038
    Abstract: A milkweed processing machine includes a housing having an inlet end and an outlet end. Milkweed pods are introduced into the inlet end and conveyed to a pod cracking chamber whrein a cylinder having rigid spikes projecting radially therefrom cracks the pods. The cracked milkweed pods are then conveyed to a picking chamber wherein a plurality of cylindrical members having fingers projecting therefrom will pick and loosen the floss and seeds from the cracked milkweed pods. The picking cylinders are arranged in parallel relationship and rotate in opposite directions. The picked and loosened floss and pods are then conveyed to a fluffing chamber which includes a rotating cylindrical member having a plurality of fingers which further fluff the loosened floss to remove the seeds from the floss. A fan directs a current of air through the loosened and picked floss materials to lift the floss and carry it to an outlet.
