Definitions

  • This invention relates in general to crushing and grinding apparatus, and in particular to an apparatus for breaking asphalt into substantially uniform pieces of a predetermined size for recycling.
  • U. S. Patent 5,440 (DeHaven) a machine is described for breaking up coal into smaller particle sizes, employing a rotating drum having a series of teeth meshing with holes in a fixed plate. The drum is provided with a plurality of apertures through which the coal may fall.
  • U. S. Patent 3,933,086 (Standing) a machine for separating dried fruit aggregates is disclosed and includes a pair of rollers having teeth along their respective peripheries for separating individual fruit pieces by the differential speed of the pairs of rollers.
  • Patent 271,589 (Anderson) a pair of flexible crushing rolls or cylinders are disclosed with peripheral slotted perforations, through which clay is forced by the pressing and abrading action of the rolls into the interior of the rolls and thereafter subjected to the actions of cutters or beaters.
  • Other references of interest include U.S. Patent 175,774 (Siehmon) ; U.S. Patent
  • the present invention relates to an apparatus for breaking asphalt into substantially uniform pieces of a predetermined size, so that the resulting smaller pieces may be recycled.
  • the apparatus is characterized by its construction comprising a pair of parallel, counter rotating perforate hollow cylinders. One of the cylinders is movable along a direction transverse to axis of rotation, whereby the distance between the two counter rotating cylinders may be varied in pre- determined fashion.
  • the invention is further characterized by the providing of a plurality of apertures, preferably in the form of rectangles, through each cylinder. In the operative disposition of the apparatus, the apertures formed through each cylinder are in a nonaligned relation to each other. That is to say, the apertures formed through one cylinder are not substantially congruent to the apertures of the other cylinder.
  • FIG. 1 is a side view of the apparatus for breaking asphalt of the present invention.
  • FIG. 2 is a top plan view, in fragmentary detail, of the adjacent hollow cylindrical drums of the present invention.
  • FIG. 1 Illustrated in Figure 1 is a side view of the apparatus generally indicated at 11, for breaking asphalt.
  • the apparatus 11 includes a supporting structure 13 which is disposed substantially horizontally and may comprise a pair of parallel I-beams mounted on legs (not shown) on a supporting surface (not shown) . Attached to the horizontal supporting structure
  • first pair of bearing hangers 15 which support a shaft 17.
  • Attached to the shaft 17 are a plurality of spokes 19 radiating outwardly and connected to a first hollow cylindrical drum 21.
  • the first hollow cylindrical drum 21 is substantially perforate since it is provided with a plurality of radially extending apertures 23 disposed in an arranged pattern through the first orum surface 24.
  • the radially extending apertures 23 are substantially rectangular projections on the cylindrical surface 24 of the first hollow cylindrical drum 21.
  • the radially extending apertures 23 are shown disposed in a uniform
  • the apparatus 11 for breaking asphalt also includes a sliding assembly 25
  • Sliding assembly 25 includes a pair of elongated traverse posts 27 which are adapted to slide on the base surface of the I-beams forming the horizontal supporting structure 13.
  • the elongated traverse posts 27 may be in the form of a reversed "C" disposed on the base portion of the I-beam.
  • the sliding assembly 25 also includes a pair of underframes 29 which are attached to the elongated traverse posts 27 and form a substantially rectangular underframe. Attached to the sliding assembly 25 are a second pair of bearing hangers 31 which provides bearing support for a second shaft 33.
  • the second shaft 33 is attached to a second hollow cylindrical drum 35 by a plurality of radially disposed second spokes 37.
  • the second hollow cylindrical drum 35 is also provided with a plurality of radially extending openings 39 arranged in a predetermined pattern on the surface 40 of the drum 35.
  • the pattern on the drum 35 and the drum 21 are arranged so that when they are juxtaposed the pattern on the drum 21 is offset from the pattern of the drum 35.
  • the offset can be achieved by creating different patterns for the drums 21 and 35, or alternatively, by disposing identical drums 21 and 35 slightly offset longitudinally with regard to their axes of rotation.
  • the apparatus 11 is driven by a drive mechanism 41.
  • the power for the drive mechanism is provided by a -motor 43 having an output shaft 45 connected to a motor sprocket 47.
  • first idler bearing hanger 42 supporting a first idler shaft 44 to which a first idler sprocket 46 is attached.
  • the first idler bearing hanger 42 may be attached to the upper portion of the underframe 29 or to the bottom portion of the elongated traverse post 27.
  • a second idler bearing hanger 49 is attached to the bottom of the underframe 29 to support a second idler shaft 51 which is attached to a second idler sprocket 53.
  • a second drum sprocket 55 is attached to the second shaft 33 which is connected with the second hollow cylindrical drum 35.
  • a first drum sprocket 57 is connected to the first shaft 17, which is connected to the first cylindrical hollow drum 21.
  • a roller chain 59 is operatively connected to motor sprocket 47 on the drive shaft 45.
  • the roller chain 59 is also connected to first idler sprocket 46, second idler sprocket 53,and second and first sprockets 55 and 57, respectively.
  • the operation of the device is illustrated in Figure 1 which indicates the direction of travel of the roller chain 59 with arrows A.
  • Drive shaft 45 turns counterclockwise thereby causing the chain 59 to turn the second hollow cylindrical drum 35 in a clockwise direction as indicated by arrow B.
  • first hollow cylindrical drum 21 While at the same time turning first hollow cylindrical drum 21 in a counterclockwise direction as indicated by arrow C.
  • the counter rotating drums 21 and 35 provide the necessary stresses on large particles of asphalt 61 to break the large particles 61 into smaller particles 63.
  • the size of the smaller particles 63 can be controlled by the spacing between ' the two drums 21 and 35 which in turn can be controlled by the sliding assembly 25.

Abstract

Un appareil (11) pour broyer de l'asphalte comprend une paire d'organes cylindriques parallèles, creux et perforés (21 et 35) tournant en sens opposé. L'intervalle entre les centres des organes cylindriques (21 et 35) peut être ajusté pour permettre le chargement de grandes particules (61) d'asphalte dans l'écartement défini par les deux organes cylindriques (21 et 35), puis leur cassage en morceaux uniformes plus petits (63) de dimensions prédéterminées.
