Definitions

  • the present invention relates to a mowing machine in which a weeding rotary body constituted by providing a weeding plate with a back blade having a back blade formed between a large number of projecting pieces on the outer periphery of a rotating body is driven by a prime mover.

It is a technology to prevent the spraying of pesticides. Background art
  • This equipment cannot completely remove long cut grass or grass pieces by the rotating wind, and rotates the weeding board at a speed that does not cut the grass, so that the grass pieces gradually stick to the projections and back blades. Therefore, it is difficult to continue the mowing work by lowering the rotation speed.
  • short prongs have the disadvantage of reducing the effect of loosening the lawn in the lawn and losing the work of hanging the thick and hard target stems, which are rarely mixed, to float the roots.
  • the preferred working speed of weeding boards is not clear.
  • Similar devices include lawn mowers and disc blade type mouth mowers, but they can selectively use soft grass in the lawn! It is not a device of the same kind because it has no function at all, but in other words, it is possible to remove multiple weeding boards from the weeding rotating body at the same time, or to remove the weeds during the mowing rotation. There was no proposal and no need for it. Because the lawn is usually the thinnest and softest in the grass, but the hard outer skin is hard to cut, so when we hit a high-speed cutting blade directly, weeds and lawns that are already attached to the front edge of the blade are themselves. Pushing, cutting and scraping before the self occurs, and the action is continuous during the work rotation, so sticking and entanglement could be ignored during the sharp working period of the cutting blade. .
  • a hedge trimmer is mainly used for pruning a tree, and a small one is used for pruning a small area.
  • the method of use is to determine the lower part of the upper and lower two mowing boards,
  • the reciprocating motion is repeated at right angles to the direction of travel of the mowing plate.
  • both sides of the inner side of the protruding piece are formed as side blades, and 3 the foliage that has entered between the protruding pieces is the side of the upper and lower mowing boards. It is cut off with leaves, and the back blade facing the direction of travel does not cut foliage alone. Also, in the direction of travel, it is only the speed of swinging by hand to the left and right. It does not apply cutting force to foliage at a considerable speed in front of the back blade at about 8 US per second.

Technique permettant d'éviter toute pollution par produits chimiques agricoles lors de la pulvérisation d'herbicides, et mettant en ÷uvre une tondeuse à gazon dont la structure comporte: une pluralité de plaques tondeuses (2) portant des lames encastrées, chaque plaque étant dotée d'une pluralité de parties saillantes (3) dont les extrémités avant présentent chacune une arête antérieure coupante (4), et de lames encastrées et acérées (5) disposées dans des positions fixes entre lesdites parties saillantes et légèrement en retrait par rapport aux extrémités avant de celles-ci, lesdites plaques tondeuses étant fixées à la périphérie externe d'un corps rotatif de sarclage (10) et disposées de manière que les lames encastrées (5) de l'une des plaques s'écartent de celles des autres tout en étant en phase lors de la rotation, et que les lames encastrées balayent ensemble toute la périphérie dudit corps rotatif de sarclage (10), lequel est monté rotatif dans les deux sens sur le corps de la tondeuse; ainsi qu'un balayeur à gazon (25) monté sur le corps de la tondeuse dans une position plus élevée que celle de l'arbre porteur de sorte qu'il se trouve à proximité dudit corps rotatif de sarclage, ou en contact élastique avec celui-ci, afin qu'il puisse simultanément balayer, faucher et ramasser l'herbe conjointement avec un corps rotatif ramasseur d'herbe (55) quel que soit le sens de marche de la tondeuse. Ainsi, un fonctionnement continu et prolongé commandé par un moteur devient possible, et le corps rotatif de sarclage (10) tourne à une vitesse de rotation régulée et est constitué d'un arbre porteur (24) et d'une sarcleuse rotative (9) montés démontables l'un de l'autre dans la structure. En outre, toutes les plaques tondeuses sont amovibles et remplaçables de manière simultanée et rapide, la modification, l'affûtage et l'entretien peuvent s'effectuer même sur le lieu d'utilisation, le fauchage peut s'effectuer en marche avant ou en marche arrière, la tondeuse peut être télécommandée, et les deux extrémités de la tondeuse rotative (64) sont fixées sous une jupe (62) placée sous un rotor (60) fixé à l'arbre tournant.
