Patent number: 4675520Abstract: A method and device for optically counting small particles, like grains of seed and fertilizer and other materials employed in agriculture. The particles to be counted travel past a test field, interrupting as they do so a beam of light between a light emitter and a light detector. To make it possible to detect even several particles in the test field at the same time and to make the counting generally more precise, individual points where the path of a beam of light is interrupted by particles passing through the grid are detected in sequential scanning cycles by beams of light that create an optical grid and are retained in the form of information describing one or more particles, information describing the particles and obtained in different scanning cycles are compared, and counting signals that correspond to the number of individual particles passing through are derived from the variations in the interrupting points determined during the comparison.Type: GrantFiled: May 24, 1985Date of Patent: June 23, 1987Assignee: Amazonenwerke H., Dreyer GmbH & Co.

Patent number: 4651331Abstract: Method of counting particles of seed, fertilizer, and other materials employed in agriculture acoustically. The particles to be counted are conveyed against an impact plate in such a way as to start it oscillating, generating electric signals that are processed to determine the number of particles. In order to count the exact number of individual particles passing a test point with relatively high precision and by acoustical means, at least one definite oscillation amplitude that is characteristic of the impact of one particle is determined and stored and a comparable actual oscillation amplitude is determined as the particles strike against the impact plate, is compared with the stored oscillation amplitude, and, if it is shorter than the characteristic amplitude, one particle counted, or, if it is higher than the characteristic amplitude, the inference made that another particle has struck the plate.Type: GrantFiled: May 24, 1985Date of Patent: March 17, 1987Assignee: Amazonenwerke H.

Patent number: 4520874Abstract: An agricultural machine with a frame on which tool rotors are mounted on upright shafts in a row extending across the direction in which the machine travels. The rotors are driven by a horizontal driveshaft that is segmented and interlocked by couplings. Each segment of the driveshaft is a component of one of the angular gears that drive the tool rotors. The horizontal driveshaft is coupled, through a coupling device that is inside the housing of a main train mounted on the frame, with the output gearwheel of the main train and hence driven by it. Guides for aligning the central axis of the components of the driveshaft with the center line of the output gearwheel of the main train are positioned in a known way at least between the main train and the gears of a tool rotor that are immediately adjacent to it. The coupling device has a coupling component that is rigidly attached to the components of the driveshaft that extend into the main train.Type: GrantFiled: February 25, 1983Date of Patent: June 4, 1985Assignee: Amazonen-Werke H.
