Abstract
Description
- 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.
- The containers or bins of the above type which have been used and proposed so far are facing an annoying problem of segregation of the components of the.mix when they fall into it from the end of a conveyor at the top of the container. The common way to avoid undue segregation is to always keep the container at least half full, so that the incoming bituminous mix falls a shorter distance and is thus subject to less segragation. This is only partly satisfactory concerning segregation and, besides, it results that, in fact, only half of the container or bin is really useful. Those previous bins are erected by crane and thus need substantial time and labor before they are ready. Another disadvantage is that those bins are only made to store bituminous mix and the fuel used on the site and the conveyor to load such bin must come in other trucks.
- It is a general object of the present invention to provide a roadable storage container of the above type, which substantially eliminates the problem of segregation in the bituminous mix that is loaded in it.
- It is another object of the present invention to provide a roadable storage container of the above type which is self-erecting and which thus avoids the need of a crane for its erection on the construction site.
- It is a further object of the present invention to provide a roadable storage container of the above type, which efficiently and fully uses its volume, not only to store a load of bituminous mix but also to carry required fuel and the conveyor needed to load the bituminous mix in it, and to thus avoid the need of other trucks to transport the fuel and the conveyor.
- It is also an object of the present invention to provide a roadable storage container of the above type, which is roadable or towable on the road by a truck tractor and constructed and arranged to be readily lifted to an operative position.
- It is still another object of the present invention to provide a roadable storage container of the above type that is provided with a conveyor arrangement particularly adapted to avoid loading of the bituminous mix by dropping it in the container from its top.
- It is a still further object of the present invention to provide a roadable storage container that is provided with a bituminous mix compartement 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 the trucks.
- It is also an object of the present invention to provide a roadable storage container of the above type, which is adapted to provide loading inlets which are arranged to discharge the bituminous mix in the storage bin with minimum of the mix to thus minimize its segregation.
- The above and other objects and advantages of the present invention will be better understood with reference to the following detailed description of a preferred embodiment thereof which is illustrated, by way of example, in the accompanying drawings, in which:
- Fig. 1 is a side elevation view of a roadable storage container, according to the present invention and shown attached to a truck tractor drawn in dashed lines;
- Fig. 2 is a rear view of the same roadable storage container;
- Fig. 3 is a section taken longitudinally through the same roadable storage container with the latter shown in erected operative position;
- Fig. 4 is an enlarged view of a portion of Fig. 3, particularly illustrating a section of a conveyor in the process of loading a bituminous mix in a compartment according to the present invention and
- Fig. 5 is a cross-sectional view as seen along line 5-5 in Fig. 4.
- The illustrated readable storage container 10 is adapted to be towed by a truck tractor 11, of conventional construction. For that purpose, the roadable storage container 10 includes a trailer chassis and
road wheel assembly 12. - The trailer chassis and
road wheel assembly 12 com- prises a trailer 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. Theelongated storage bin 15 is provided with aforward 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 thestructural projection 17 and has its other end connectable to abracket 20 on the chassis of the truck tractor to elevate the elongated storage bin to its operative position, shown in fig. 3.Pads brace 24 is connected in position between the trailer chassis and the storage bin to secure them relative to each other. The inside of thestorage bin 15 is divided by atransverse partition 25 into a rear fuel tank at 26 and afront compartment 27 forbituminous 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. Thetrough 29 is formed with a rear open and providing an inlet at 30 for loading of the bituminous mix on theconveyor 31 of the drag type that runs in thetrough 29 and extends substantially co-extensive therewith.Conveyor 31 is driven by a motor 31' in the direction ofarrows 31". A series ofloading inlet apertures 32 are provided in thetrough 29 in registry with thebituminous mix compartment 27 and serially extend co-extensive therewith in the longitudinal direction of thebin 15. Theloading inlet apertures 32 are geometrically shaped, such as a square, to define an apex pointing toward the upstream open end of the trough. Eachinlet aperture 32 is provided with a baffle 32' extending from the top ofaperture 32 downwardly intocompartment 27. Thedrag conveyor 31 is provided withdrag blades 33 of truncated V-shape configuration, as shown in fig. 5. The lowermost longitudinal surface portion of thestorage bin 15 is formed with an unloading aperture registering with the lowest rear end of thebituminous mix compartment 27. A trap door at 34, actuated by ahydraulic cylinder 35, selectively opens and closes the unloading aperture to unload bituminous mix intotrucks 36. - 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 pad 21 to support the front of the bin. Thebrace 24, or any other appropriate bracing, is then put in place to stabilize the bin. - A mixer and
heater 37, of any appropriate construction, 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 theblades 33. The bituminous mix is loaded in thecompartment 27 through theloading 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 thecompartment 27 always through anaperture 32 which is not much higher than the level of material in the compartment at any particular time. 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 theconveyor trough 29 throughapertures 32. - The
mixer heater 37 is fed with fuel oil fromfuel tank 26 and it will be noted thatconveyor trough 29 is enclosed inbin 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 ofcompartment 27 can be used, namely it can be emptied completely if called for by the scheduling of thedelivery trucks 36.
