  • Patent number: 4597250
    Abstract: A method of preparation or conditioning of stalk agricultural products includes formation of a field or a space in which an electrical potential difference forms current- and spark shocks. An arrangement includes supports provided with electrodes which are arranged in pairs opposite to one another, and the support forms therebetween a feeding passage for the product. One of the supports can be formed as a driven organ. The arrangement can be associated with a mowing mechanism.

  • Patent number: 4592194
    Abstract: A processing apparatus for agricultural stalk-shaped products, and wherein the products are adapted to be formed into a stream of products following cutting thereof from the ground, includes a rotatably driven conveyor element with a plurality of approximately radially outwardly extending conveyor tools separated from one another by gaps, and operatively defining a trajectory, a guidance element defining a plurality of openings, cooperating with the conveyor element for guiding the products, and forming with the conveyor element a guidance channel extending transversely to the stream of products, and wherein the guidance element intersects the trajectory near the front end and near the rear end of the guidance channel, so that the conveyor tools project at least partially outwardly through corresponding openings in the guidance element.

  • Patent number: 4345422
    Abstract: A hay-gathering machine for pulling windrows of hay, turning the hay over, and scattering it, having a rake-wheel comprising a plurality of tine-carriers radially directed outwards from an almost vertically-pointed swivel pin, wherein the tine-carriers at their outer ends are provided with rake-tines. At the end of each tine-carrier, which is directed toward the swivel pin of the rake-wheel, there is attached at least one control lever, which, for the pulling of windrows, is connected with a first open control channel in a tensional or a form-locking, or in a purely form-locking manner. The tensional or form-locking connection of the control lever with the first open control channel is made by means of a spring or the like, while the purely form-locking engagement of the control lever into the first control channel is made by means of cooperation of the roller on the control lever with a guide way which is parallel to the first control channel.
