Definitions

  • This invention relates to a soil conditioning and rock crushing machine for conditioning and treatment of soil and rocks. Particularly the invention relates to the modifying or regenerating of various soil types for which the machine can also perform as a crusher.
  • Clay soils create problems in the building industry and also in earth works. It is well known that a soil conditioning material is spread over areas of clay, the conditioning material being for example lime, gypsum or cement. More recently machines are available to condition clay soil. The clay is scraped or dug from the ground, and loaded onto a conveyor belt of the machine where it is fed with conditioning material into a mixer where it is mixed and fed to a discharge conveyor.
  • One such machine is described in PCT/IB2008/002545 in which one or more rotors are positioned in a mixing chamber vertically spaced from each other.
  • the mixing chamber includes shaped doors to deflect the material ejected from an upper rotor down to a lower rotor for further mixing.
  • the uppermost rotor picks and or chops the incoming soil upwardly from the end of the in-feed conveyor against surfaces shaped to deflect the material to the next lower rotor which also ejects the material upwardly against further shaped surfaces to deflect the material either to a third rotor or to a discharge conveyor.
  • the shaped deflecting surfaces comprise hinged doors which can be adjustably positioned to and from the adjacent rotor depending on the type of soil being conditioned.
  • the doors with the shaped deflecting surfaces are thus situated on one side of the mixing chamber.
  • soil accumulates between the rotors on the opposite side of the mixing chamber to the shaped deflecting surfaces.
  • a further object of the invention is to facilitate the removal of accumulated material from the wall of the mixing chamber opposite the wall containing the shaped deflecting surfaces.
  • a still further object of the invention is to facilitate the removal of accumulated material on a wall of the mixing chamber between two mixing rotors.
  • a mixing chamber containing one or more mixing rotors, the mixing chamber having walls, characterised in that a portion of a wall on which soil accumulates is movable to be adjacent a rotor to substantially remove the accumulated material for that portion of the wall.
  • the mixing chamber houses one or more rotors, the rotor(s) ejecting the material against shaped surfaces to deflect the material onto a further rotor, the portion of the wall on which the material accumulates being opposite to the deflecting surfaces.
  • the movable wall in the form of a flap is between two rotors and is movable to be adjacent a rotor whereby rotation of the rotor substantially removes the accumulated material.
  • the flap comprises a quadrant of a cylinder hinged to the wall so that the quadrant of the circle moves to adjacent the second rotor while maintaining a sealing condition in the wall.
  • Figure 1 is a cross sectional view of portion of a soil conditioning machine showing the accumulation of material between the uppermost and next lower rotor
  • Figure 2 shows the same cross sectional view in the cleaning position.
  • a conveyor 2 feeds the material to be conditioned into the chamber 1 to be conditioned by rotors 3 and 4.
  • the rotor 3 picks the material from the end of the conveyor 2 and ejects it against the shaped deflecting surfaces 5 which deflects the material against rotor 4 for further conditioning.
  • the rotor 4 ejects the material against further deflecting surfaces 6 to deflect the material on to a discharge conveyor 7, or in another embodiment, not shown, to a third rotor for further conditioning.
  • the deflecting surfaces 5 are part of a movable door which can be adjusted to and from the rotor 3 depending on the type of material being conditioned.
  • deflecting surfaces 6 are part of a movable door 9 also adjustable to and from rotor 4 depending on the type of material being conditioned. As shown in figure 1 , during operation of the machine there is a tendency for material to accumulate at 10 on the wall 1 1 opposite the deflecting surfaces 5 and 6.
  • the portion of the wall 1 1 on which the material accumulates is a flap 12 pivoted at 13 to a portion of the wall 1 , the flap 12 forms the radius of a quadrant having an arcuate portion 14.
  • a hydraulic ram 16 mounted on a fixed portion of the wall 1 1 can move the flap12 from the position shown in figure 1 to the position shown in figure 2 with the matrix close to the rotor 4. In doing so the accumulated material is substantially cleared from the surface of the matrix.
  • the arcuate portion seals on the opening in the wall 1 1 thus preventing the escape of any material being conditioned from the mixing chamber.
  • the cleaning of the matrix can take place at any time during the operation of the machine or at the same time as any other cleaning operation of the machine.

Abstract

La présente invention concerne une machine utilisée pour mélanger, traiter ou conditionner des sols ou des roches, cette machine comprenant une chambre (1) dans laquelle la matière est mélangée, traitée ou conditionnée par des éléments rotatifs (3, 4) ayant tendance à éjecter la matière contre une paroi (11) de la chambre (1) afin de créer une accumulation de ladite matière sur une partie de la paroi (11). Ladite partie de la paroi est fabriquée sous forme d'un volet (12) relié pivotant à la paroi (11) de la chambre (1) et il existe un organe d'actionnement qui permet de faire pivoter le volet (12) vers l'intérieur afin qu'il se trouve adjacent à un élément rotatif (4) pour éliminer sensiblement du volet (12), la matière accumulée.
