Definitions

  • This invention relates to a container of the type that is roadable and transportable to a road construction site to hold a bituminous mix pending its delivery by trucks.
  • US-A-1 820 521 describes a floating storage and mixing bin for bulk materials, especially coal.
  • This inclined longitudinal bin is provided with a drag conveyor for successive filling from the top through a narrow slot in the trough of the conveyor.
  • This known elongated bin is not provided with means for preventing the escape of loaded material from the open top of the bin, because such means would seem unnecessary in view of the only moderate inclination of the bin.
  • This bin is not adaptable so as to provide a tiltable roadable container for bituminous mix.
  • the object of the invention is seen in providing a roadable storage container for bituminous mix of the self-erecting type with loading means which substantially eliminates the problem of segregation in the bituminous mix that is loaded in it, which efficiently and fully uses its volume and which is erectable from the front end so as to position the unloading outlet for convenient dumping of the mix into trucks.
  • the roadable container is provided with a bituminous mix compartment and a fuel compartment relatively positioned to assist the pivoting of the storage bin between its erected and its lowered positions and to allow positioning of the unloading or discharge outlet for convenient dumping into trucks.
  • the illustrated roadable storage container 10 is adapted to be towed by a truck tractor 11, of conventional construction.
  • the roadable storage container 10 includes a trailer chassis and road wheel assembly 12.
  • the trailer chassis and road wheel assembly 12 comprises a triler chassis or frame 13, of any appropriate and conventional construction, defining a front and a rear end.
  • the rear end of the trailer chassis 13 is carried by road wheel assembly including the road wheels 14 and appropriate axle connection, not shown.
  • the roadable storage container includes an elongated storage bin 15 extending substantially co-extensive with the trailer chassis 13 and defining a front end and a rear end.
  • the front end of the elongated storage bin is pivoted at 16 to the trailer chassis 13 about a transverse pivot axis to operatively pivot between a transport or roadable position in which it rests on the trailer chassis 13 and an erected inclined position, as shown in fig. 1 and 3, respectively.
  • the elongated storage bin 15 is provided with a forward structure projection 17 at its front end for attachment to the truck tractor 11 by any appropriate fifth wheel assembly at 18.
  • a telescopic hydraulic cylinder 19 is connected at one end to the structural projection 17 and has its other end connectable to a bracket 20 on the chassis of the truck tractor to elevate the elongated storage bin to its operative position, shown in fig. 3.
  • Pads 21, 22, and 23 are provided to support the trailer chassis and the storage bin in the elevated position.
  • a brace 24 is connected in position between the trailer chassis and the storage bin to secure them relative to each other.
  • the inside of the storage bin 15 is divided by a transverse partition 25 into a rear fuel tank at 26 and a front compartment 27 for bituminous mix 28. The fuel tank thus forms a ballast to assist the elevation of the storage bin to the position shown in fig. 3.
  • the uppermost longitudinal surface portion of the elongated storage bin 15 forms a trough at 29 which longitudinally extends lengthwise of the bin.
  • the trough 29 is formed with a rear open and providing an inlet at 30 for loading of the bituminous mix on the conveyor 31 of the drag type that runs in the trough 29 and extends substantially co-extensive therewith.
  • Conveyor 31 is driven by a motor 31' in the direction of arrows 31".
  • a series of loading inlet apertures 32 are provided in the trough 29 in registry with the bituminous mix compartment 27 and serially extend co-extensive therewith in the longitudinal direction of the bin 15.
  • the loading inlet apertures 32 are geometrically shaped, such as a square, to define an apex pointing towards the upstream open end of the trough.
  • Each inlet aperture 32 is provided with a baffle 32' extending from the top of aperture 32 downardly into compartment 27.
  • the drag conveyor 31 is provided with drag blades 33 of truncated V-shaped configuration, as shown in fig. 5.
  • the lowermost longitudinal surface portion of the storage bin 15 is formed with an unloading aperture registering with the lowest rear end of the bituminous mix compartment 27.
  • a trap door at 34 actuated by a hydraulic cylinder 35, selectively opens and closes the unloading aperture to unload bituminous mix into trucks 36.
  • the storage bin After the storage bin has been towed to the proper road construction site, it is pivotally lifted by the cylinder 19 until its rear end is operatively mounted on the pads 22 and 23 and the trailer chassis 13 rests like a post on the pad 21 to support the front of the bin.
  • the brace 24, or any other appropriate bracing, is then put in place to stabilize the bin.
  • a mixer and heater 37 is positioned to discharge hot bituminous mix in the open inlet end of the conveyor assembly, so that the bituminous mix will be upwardly dragged by the blades 33.
  • the bituminous mix is loaded in the compartment 27 through the loading apertures 32 first through the lowermost one and serially through the next ones in succession as they become successively filled. There results a progressive filling of the compartment 27 always through an aperture 32 which is not much higher than the level of material in the compartment at any particulartime. This produces a sort of stratification in the bituminous mix compartment that is substantially free of segregation of the bituminous particles.
  • the baffles 32' prevent the mix from re-entering the conveyor trough 29 through apertures 32.
  • the Mixer heater 37 is fed with fuel oil from fuel tank26 and itwill be noted that conveyor trough 29 is enclosed in bin 15, and that the latter can be heat insulated so that the mix can be kept hot for a long time. Also the full capacity of compartment 27 can be used, namely it can be emptied completely if called for by the scheduling of the delivery trucks 36.
