Definitions

  • the object of the invention is to improve the accuracy in the measurement of the grain flow in a combine har- 25.
  • vester and as stated in claim 1 the invention relies on substituting beta rays, gamma rays or X-rays to per ⁇ form this measurement for sound waves or light beams, because it has been found that the attenuation or the change of such rays virtually does not depend upon other variable factors than the density of the grain flow.
  • a particularly expedient radiation source in practice is a piece of americium 241.
  • the numeral 10 designates a shaft in which a grain elevator 11 consisting of a chain conveyor with buckets is mounted. At the upper end of the elevator the grain is thrown out through a passage 12 to an intermediate chamber 13, from which it drops down into a grain tank (not shown).
  • the shaft 10 and the chamber 13 are defined by steel plates forming i.a. a horizontal top wall 14 and a side wall 15, which extends obliquely downwards from the top edge 16 of one shaft wall 17.
  • a gamma radiation source 18 in the form of a piece of americium 241 with an intensi ⁇ ty of about 1 mCi, and adjacent to this radiation source a section of the plate wall 15 is replaced by an aluminium plate 19 which attenuates the . gamma rays less than the steel plate.
  • a gamma ray detector 20 Opposite the radiation source 19 and directly above the top wall 14 there is placed a gamma ray detector 20, which preferably consists of a sodium iodide scintillator with an associated photo multiplier.
  • An aluminium window 21 is inserted in the top wall 14 adjacent to this detector.
  • the detector 20 is connected to a computing unit 23 , which has i . a . an indicator 24 , by a l ine 22.
  • the velocity at which the grain flows through the pas ⁇ sage 12 is proportional to the operating velocity of the grain elevator 11, and is thus a constant k multi ⁇ plied by the rotational velocity of one of the rollers over which the elevator belt runs.
  • the attenuation of the gamma rays from the source 18, measured by the detector 20 and produced by the grain flow, is a func ⁇ tion of the density $ of the grain flow between the source and the detector, and on the basis of these quan ⁇ tities and the cross sectional area A of the passage 12 the mass flow will be
  • the computing unit may also be designed for automatic zero point adjust ⁇ ment and to display various relevant quantities, such as e.g. capacity in barrels/hour, total amount of crop, yield in proportion to seed sown, etc.
  • the detector may be shielded against di ⁇ rect irradiation so that it just receives rays refracted by the grain flow, the scattering of the rays thus pro ⁇ vided, like the transmission attenuation being an unam ⁇ biguous measure of the density.
  • Other types of radiation sources than americium 241, e.g. X-ray tubes, and other forms of detectors than scintillation oscilloscopes, e.g. Geiger tubes, ionization chambers and semi-conductors, may be used.
  • both the radiation source and the detector may be placed in another manner in a combine harvester than shown in the drawing and described in the foregoing, just as several radiation sources and/or detectors may be used for the determination of density.

Abstract

Pour effectuer une mesure continue du débit-masse de grains défourrés dans une moissonneuse-batteuse à l'aide d'un émetteur de signaux (18) et d'un détecteur de signaux (20) placés sur leurs côtés respectifs d'un passage (12) d'écoulement de grains, on utilise une source de radiation à rayons bêta, gamma ou X, en tant qu'émetteurs de signaux. Etant donné que l'effet d'atténuation du débit des grains sur ces rayons ne dépend pratiquement pas de facteurs variables autres que la densité de l'écoulement des grains, le signal de sortie du détecteur est une expression précise de cette densité. Connaissant la vitesse de l'écoulement des grains et la section transversale du passage, le débit-masse peut ainsi être calculé avec une précision tout aussi grande.
