Definitions

  • the present invention relates to a portable device for dispensing and metering granular or powdery products, particularly herbicides or fertilizers.
  • the invention is used in the highly localized weeding or fertilizing operations often required in hobby and professional gardening, in agriculture and in any case in operations that entail the highly localized placement, on a flat surface such as for example a lawn or flower-bed, of small doses of dry and freely flowing granular and powdery products.
  • weeds including invasive ones, very often spread in lawns and must be eliminated, otherwise they quickly spread and visibly damage the lawn.
  • the aim of the present invention is to provide an apparatus that can act in a localized, fast and trouble-free manner.
  • An object is to provide a tool for metering the product used from a minimum amount up to an amount required. Another object is to provide an apparatus which is convenient in use and has low costs.
  • a portable device for dispensing and metering granular or powdery products characterized in that it comprises a container for a granular product which is associated with a discharge tube having, at its lower end, a valve which is kept closed by an elastic means and has a lever for opening it by interaction with the ground.
  • figure 1 is a view of the dispensing and metering device in a carrying condition
  • figure 2 is a view of the dispensing and metering device of figure 1 during discharge of the product
  • figure 3 is a detail view of the valve located at the base of the dispensing and metering device of figure 1
  • figure 4 is a second view of the valve of figure 3
  • figure 5 is an exploded view of the components of the valve
  • figures 6 and 7 are views of another embodiment of the valve.
  • the invention is composed of a container 1 in which the granular or powdery substance used is contained.
  • the lower part of said container 1 is connected, by means of a funnel-shaped region 3, to a tube 4 the lower end
  • valve 6 which is substantially constituted by a body with two arms, respectively 7 and 8, which are mutually coupled, arranged substantially at right angles to each other, and associated by means of a pivot 9 with a clamping device 10 that fixes the entire assembly to said tube 4.
  • valve is illustrated more clearly in figures 3, 4 and 5, where the presence of a return spring 11 is clearly shown; this spring, by acting between the clamping device 10 and the lever-like valve 6, keeps the flat face 12 of the arm 8 of the valve 6 in contact with the end part 5 of the tube 4.
  • lever-like valve now designated by the reference numeral 60 in figures
  • the tool which is carried by hand, is rested on the ground at a weed 13 so that the arm 7 of the valve 6 interacts with the ground, spacing the arm 8 of said valve from the nozzle 5 and discharging material.
  • the discharged material is thus positioned very accurately in a localized area.
  • the inside of the container 1 and of the tube 4 be perfectly smooth and devoid of any discontinuity that might lead to the forming of bridges of product that would block the flow of said product when the valve is opened for discharge.
  • the product used is conveniently a herbicide, but it is also possible to use substances which are not specifically herbicidal but are merely caustic.

Abstract

Ce dispositif de distribution et de mesure comprend un récipient (1) raccordé par une région en forme d'entonnoir (3) à un tube (4) définissant une extrémité inférieure (5). Un clapet (6) est fixé par un pivot (9) à un élément de serrage (10) relié à l'extrémité inférieure (5). Un ressort sollicitant maintient le clapet (6) en une position généralement fermée sur l'extrémité inférieure (5). Des branches (7, 8) reliées au clapet (6) peuvent être mises en contact avec le sol afin de faire tourner le clapet (6) autour du pivot (9) à l'encontre de l'action du ressort de façon à ouvrir l'extrémité inférieure (5) et à distribuer le produit (2) du récipient (1) vers une zone localisée.
