Definitions

  • the invention relates to a material spreader of the type disclosed in the preamble of patent claim 1.
  • DK Patent Specification 168963 teaches an example of a spreader of this kind which consists primarily of an open, rectangular drag frame in lo whose foremost end there is arranged a funnel-shaped, transverse-mounted asphalt feed box.
  • the feed box has a bottom opening across the whole width of the drag frame and is provided with a plurality of individually adjustable feed gates in connection with the bottom opening, and in the rear end of the frame there is arranged a plurality of levellers and an adjustable side scraper.
  • DK apparatus is not intended for really big asphalting jobs, it is clear that it is intended to be used for municipal road maintenance. This means that the primary area of application suggests a different dimensioning and design from that of the present invention.
  • US Patent 3,526,173 teaches an example of another asphalt spreader.
  • a feed box is used for the asphalt.
  • Hydraulic cylinders are provided for adjusting the capacity/thickness, and the width is also adjustable.
  • the US apparatus also does not have the same primary area of application as the invention whose technical solution 25 differs clearly from the prior art.
  • SE Published Patent Application 417 117 teaches a material spreader which to a certain extent seems to have the same area of application as the invention.
  • the SE apparatus comprises a trough-like box which is arranged to be towed behind a vehicle.
  • the box is secured to the vehicle by means of hydraulically operated arms so that it can 35 be inclined in order to empty out the material/asphalt that is to be laid.
  • Adjustable side walls are provided in the box to enable the width of the asphalt layer to be adjusted. 2
  • the thickness of the layer can be adjusted.
  • the material spreader of the invention is primarily intended to be used for spreading road material such as asphalt, oil gravel and gravel, but can also be used for spreading other materials such as, for example, shingle, quarry waste, concrete etc. In the following exemplary embodiment of the invention, it will however primarily be described in connection with asphalt spreading.
  • the object of the invention is to provide a material spreader which is very simple in structure and operation, which is well-suited to asphalt laying on small areas such as footpaths, small side streets and other small roads, pavements, car parks, multi-storey car parks etc.
  • the invention is also highly suitable for patching and filling potholes and grooves resulting from wear from, for example, studded tyres, as it is very easy to portion and spread the filling material. It is also well-suited to groundwork and in particular the adjustment of sub-bases.
  • the possibility of providing a vibrator as a part of the spreader eliminates or reduces the need for additional compacting equipment when several layers are to be laid. Also, in the laying of heating cables, where a thin base layer of asphalt is laid first, then the heating cable is placed thereon, followed by a top layer on top of the cable, the invention has proved to be well-suited.
  • Figs. 1 A- IB show the apparatus according to the invention, hitched to a tool carrier in the form of a mini-tractor, as a perspective drawing and side view respectively.
  • Fig. 2 shows the spreader box according to the invention in perspective, see in part from behind;
  • FIG. 3 shows enlarged details of the left-hand corner of the box shown in Fig. 2;

  • the plate 6 is arranged at a suitable angle ⁇ to the horizontal plane. This angle may be in the range of 30° to 70°, and preferably around 45°.
  • the plate 6 may be made so that it forms the inner bottom 15 which together with the flanges 14 defines a slideway or guideway for the bottom plate 12.
  • On the outside of the front wall 4 there is provided a suitable fastening means 16 for operating levers or attachment bars arranged on the tool carrier or vehicle, for example, the mini-tractor.
  • the end plate 5 rests against the end wall 3 and forms a gate opening in the back edge of the box 1.

  • the end plate 5 is preferably made of a robust steel plate, but may also be equipped with reinforcing elements (not shown).
  • Figures 8 and 9 show a modified version of the end plate 5. This is intended for spreading material in a non-level profile, for example, when filling wear grooves in a road surface or the like.
  • the plate consists of at least two plate members that are joined by means of an adjustable screw device 17 for the "pitch" of the plates, and with the aid of a through-going bolt 18 about which the plates can pivot.
  • the pitch is preferably in the range of 0-5°.
  • the support in the adjustment screws 8 must be rotatable and the length of the composite plate must be dimensioned so that the plates can be turned behind the sliding frames 10.
  • the material spreader 1 can also be equipped with a vibrator 19. This may be arranged behind the inclined plate 6 and mounted in a bracket 20 arranged directly on the slide plate 7 as shown in Figs. 10 and 11.

  • Figs. 1A and IB show an example of the material spreader in use.
  • the amount of surfacing and the speed and thickness can be adjusted in a simple manner by adjusting the position of the bottom plate 12 and thus the horizontal opening of the bottom gate, and also the vertical position of the end plate 5 and thus the gate opening or adjustment height of the rear wall portion of the box 1.
  • the maximum horizontal opening is indicated by means of the letter B in Fig. 5.
  • Figs. 6A and 6B show schematically an example of the spreader in use during groundwork.
  • the box 1 can be tilted backwards and lowered with the end plate 5 closed and the bottom plate suitably opened. The device is then lowered to a desired level and pulled behind the machine. The excess material will be collected in the box. Once the box has become sufficiently filled, the hydraulically operated bottom plate or gate 12 is closed and the tool carrier with the apparatus is used to transport the material for further spreading or dumping.

Abstract

L'invention concerne un épandeur de matériaux comprenant un organe compartiment en forme d'entonnoir, monté de manière transversale et conçu pour être remorqué par un véhicule à moteur. Ce compartiment, qui est tracté par ce véhicule à l'aide d'organes de remorquage, présente une ouverture inférieure et un dispositif de nivellement permettant de réguler l'épaisseur de la couche destinée à être déposée. Ce compartiment (1) comporte une plaque coulissante (7) qui s'étend sur toute la largeur et sur une grande partie du fond de ce compartiment (1), l'ouverture permettant de répandre les matériaux étant par ailleurs constituée d'une plaque inférieure mobile (12) placée sur un organe support (14) lui-même situé sur les parois latérales (2) du compartiment, et d'une plaque d'extrémité mobile (5) disposée sur la paroi d'extrémité (3) dudit compartiment (1), à proximité de la plaque inférieure (12). L'épandeur de matériaux de cette invention, qui présente une structure et un mode de fonctionnement très simples, convient pour asphalter des zones réduites comme des voies piétonnières, des rues transversales ou d'autres routes secondaires, des chaussées, des parcs de stationnement, des parcs de stationnement à plusieurs étages, etc. Cet épandeur permet également de reboucher les nids-de-poule dans la mesure où il peut à la fois diviser et répandre le matériau de remplissage. Cet épandeur peut par ailleurs servir dans des travaux de terrassement, en particulier pour niveler des sous-sols. Cette invention est particulièrement utile dans la pose de câbles chauffants, qui nécessite la formation d'une fine couche d'asphalte de base sur laquelle le câble chauffant est destiné à être déposé, une couche supérieure étant finalement formée sur ce câble.
