Definitions

  • the present invention relates to a crusher intended to fragment stones of too large dimensions.
  • the first way is to collect the stones and bring them together in a "scree"; which can be done by hand, according to the ancestral method or using mechanized means.
  • the second way consists, after having eliminated the very large stones, to reduce in gravel from 2 to 4 cm in diameter, the soft stones of average dimensions using mechanized shredders implemented by a tractor.
  • the first type is represented by fairly bulky equipment intended for public works and not suitable for agricultural work.
  • the second kind is represented by machines, extrapolated from brushcutters, equipped with mobile hammers, to avoid jamming, driven in rotation at high speed in order to keep the hammers in the working position: which leads to fairly considerable inertia effects which cause the deterioration of the PTO and poses problems of balance.
  • the stone crusher according to the invention overcomes the drawbacks mentioned above because its operation is not based on striking the stones to be ground, but on their nibbling: which makes it possible to rotate the rotor at a speed four times slower than that of the rotors which equip existing shredders: which is made possible, in particular, by the fixity of the hammers, the number of which makes it possible to nibble on very large stones without overheating the hammers, or unbalancing the rotor.
  • This impact and crushing stone crusher is mainly characterized in that the hammers are rigidly and regularly fixed to the periphery of a rotor and in that they come to tangent an anvil fixed to the chassis, upstream of the rotor and in parallel to the latter, in that the position of the rotor is adjustable in height relative to the chassis, in that the sides of the box surrounding the rotor are equipped with spacers, in that the front of the chassis is provided with several rows contiguous chains suspended and in that the rear of the chassis is equipped with an articulated apron with adjustable travel.
  • the steel hammers of parallelepiped shape are welded to the rotor by pitching it at their lower rear edge.
  • Their upper front edge is reinforced by an addition or a tungsten carbide pellet or equivalent.
  • the anvil fixed to the chassis in front of the rotor, consists of a square steel profile, one of the sides of which is arranged parallel to the ground.
  • the hammers are distributed uniformly in several parallel rows, regularly spaced, in a staggered arrangement.
  • the rotor is rotated, in the opposite direction to the normal direction of rotation of the wheels of the towing machine, by means of a longitudinal shaft, a bevel gear, a transverse transmission shaft and pulleys and belts or sprockets and chains, mounted at each end of the drive shaft and the rotor shaft.
  • the chassis supported by two rails, consists of two torsion bars connected by crosspieces.
  • the rotor is mounted in a box, openable from above, secured to the chassis, supported by bearings fixed on the sides of the box by means of a plate, bolts and lights, allowing vertical adjustment with respect to the ground. by means of devices made up of slides fixed to the box, of the plate, forming a slide, mounted between the bearings and the walls of the box, of screws equipped with a crank and of nuts fixed to the box.
  • Spacers arranged on the sides, consist of flanges forming pads, tapered on the front, arranged at right angles to the lower part of the box, connected to the upper part of the box by a metal plate forming a protective casing for the transmission .
  • the chassis 1 is made integral with the three-point attachments 2 of the tractor by means of rails 3 and that the chassis 1 supports a box 4, provided with a cover 5, to the interior of which is mounted, by means of bearings 6, adjustable in height by a notch 7 and lights 8, a rotor 9 at the periphery of which are fixed by welding rows of hammers 10 arranged in staggered rows.
  • the rotor 9 is rotated by a longitudinal shaft 11, connected to the power take-off of the tractor, a bevel gear 12, a transverse shaft 13, pulleys 14 and 15 and belts 16.
  • the anvil 17 is mounted across the chassis 1, in front of the rotor 9.
  • the hammers 10 are fixed, by a weld bead 21, to the rotor 9 so as to tangent the rotor at their rear lower edge 10a, while the upper front edge 10b is reinforced by an addition of tungsten carbide 22.
  • the spacers consist of flanges 23, forming pads and tapered on the front, connected by a metal plate 24 to the upper part of the box in order to constitute a protective casing for the transmission.
  • the rotor 9 taking into account its direction of rotation and its mass, pushes in front of it, during its movement, the large stones which it progressively fragments using the hammers. 10, since the anvil 17, which the hammers come to graze, forces the stones to remain under the frame all the time that their splitting is not sufficient to be thrown back from above, passing between the hammers 10 and being driven by successive rows thereof, arranged in staggered rows. During these operations, the chains 18 and the deck 19 oppose the projections.
  • the cover 5 arranged at the top of the box 4 provides access to the hammers 10 to check their condition and reload them if necessary.
  • the notch 7 and the lights 8 allow, after loosening the bolts fixing the bearings 6 to the housing 4, to vary the vertical position thereof by action on the crank 25 which ensures, through the nut 26, the screw 27 and the plate 28 forming a slide, the precise movement of the bearings 16-relative to grooves 29 forming a slide. It is thus easy to obtain, for example, a space of a few centimeters between the ground and the end of the hammers 10.
  • the stone crusher according to the invention is intended mainly for stone removal from fields, but it can also be used to fragment stones in quarries at constant level or, by reducing the width of its rotor, to dig trenches in particularly stony places.
