Definitions

  • This invention relates to a bottom discharge device, especially for vehicles intended to preferably carry dry fine- grained material, which device comprises a discharge door and means for moving the door between a closed and an open position, or vice versa.
  • the discharge doors were constructed to be opened outward. This involves problems of sealing the doors against the bottom portion of the vehicle. By leakage occurring during the transport, serious inconveniencies arise due to the dust, which forms of the dry fine- grained material and penetrates everywhere. This results in substantial dirt accumulation which, of course, deteriorates still more the sealing function of the doors.
  • the present invention has the object to produce a bottom discharge device, which eliminates the aforesaid problems, in that the doors are self-sealing by action of the pressure from the goods in the vehicle. This is achieved by a device, which has been given the characterizing features defined in the attached claims.
  • Fig. 1 is a schematic lateral view of a vehicle with a bottom discharge device according to the invention
  • Fig. 2 is an end view of the vehicle according to Fig. 1,
  • Fig. 3 is a vertical section along the line III-III in Fig. 5
  • Fig. 4 is a view along the line IV-IV in Fig. 3, and
  • Fig. 5 is a horizontal view of the bottom discharge device according to the invention. As appears from Figs. 1 and 2, the vehicle 1 shown schematically is provided with a bottom discharge device which in greater detail is shown in Figs. 3-5.
  • a draw rod 3 extends vertically upward from the bottom discharge device 2 and terminates at the embodiment shown in a handle 4 of some kind, which is located above the charging doors 5 of the vehicle.
  • the draw rod 3 extends through two guide means 6 and 7 within the vehicle 1.
  • the bottom discharge device 2 is manufactured as a separate unit and butt- welded on the bottom portion of the vehicle bucket.
  • the bottom discharge device 2 comprises two doors 9. On the lower side of each door 9 a link pair 10 are hingedly attached to a first axle 11, and the opposed ends of said pair 10 are hingedly connected to a second axle 12, the ends of which are received in metal sheets 13 with fixed position relative to the vehicle 1.
  • each door 9 two projecting sheet metal lugs 14 are attached in spaced relationship to each other and are bridged by an axle 15, which at its portion located between said lugs 13 is pivotally connected to an attachment member 16, which is common for both doors and mounted downwardly on the draw rod 3.
  • the doors along their upper and lower edges abut sealing strips 17a and 17b.
  • the lateral edges of the doors 9 in a corresponding manner abut sealing strips.
  • the edges of the doors 9 are bent dowmvard an thereby penetrate down into the sealing strips 17a and 17b when the doors are loaded by goods.
  • the invention is not restricted to the embodiment described above. It can be imagined, for example, that instead of an external lifting means a screw lifting means is built-in in the draw rod 5 and actuated, for example, by a wheel or crank.

Abstract

Dispositif de dechargement par le fond (2), notamment pour vehicules (1) destines au transport de materiaux constitues de particules fines et seches. Dans les dispositifs connus de ce type, le materiau transporte fuit par les portes de dechargement. Le materiau etant finement divise et sec, il se forme de la poussiere, ce qui presente de nombreux inconvenients. La presente invention a pour objet de prevoir un dispositif de dechargement par le fond (2) dans lequel la fuite du materiau est eliminee. Ce resultat est obtenu par le fait que les portes de dechargement (9) s'appuient de haut en bas sur les bords de l'orifice de dechargement. Les bords de l'orifice de dechargement sont de preference munis de bandes formant joint (17a, 17b), bandes contre lesquelles s'appuient les bords des portes de facon etanche. Le materiau transporte appuyant sur les portes vers le bas et les pressant contre les bords de l'orifice, le dispositif est etanche per se.
