Definitions

  • the present invention relates to an improvement to hopper wagons, containers, trucks intended for the transport of products such as cereals or any other powdery or granular product.
  • Hopper cars used in the transport of these products have drain openings at the bottom of the hopper, generally closed by horizontal or oblique hatches, sliding in a horizontal plane. If the construction of such hatches does not pose technical problems, it is not the same for their use.
  • the present invention relates to a hopper container such as a hopper wagon, container or truck provided under the hopper with one or more openings for the flow of the material it contains and relates to an opening device to large rectangular horizontal hatches sliding horizontally perpendicular to the horizontal axis of the wagon, comprising two juxtaposed half-doors, each comprising on the side opposite the side adjacent to the second half-door, at least two opening rods and levers, the levers being pivotally mounted on the same shaft parallel to the axis of the wagon.
  • the two parallel shafts are mounted by any known means on a transverse control shaft provided at each end with a flywheel, this assembly allowing the simultaneous rotations, of the same value and in opposite directions, of the two lever control shafts.
  • the device is characterized by the fact that the link between the link exerting traction on one of the two half-hatches and the control mechanism is done with a significant mechanical clearance so that one of the two half-doors opens notably after the other, the time lag of the opening of the second half hatch compared to the first being a function of the importance of this game.
  • each half-hatch is done by means of link and lever articulated one on the other, the link and the lever of the second half-hatch being articulated at by means of an axis moving in a window whose length determines the magnitude of the offset at the opening.
  • This device therefore opens the hatch in two phases: the first phase corresponds to the opening of the first half-hatch, the second phase corresponds to the simultaneous opening of the two half-hatches.
  • the two half-hatches are not of the same width, the difference in width being equal to the length of the recess.
  • the hopper 1 shown diagrammatically in FIG. 1 has a flow opening 2. This opening is closed by two horizontal, rectangular half-doors 3 and 4, juxtaposed along the longitudinal axis of the wagon carrying the hopper. On each half-hatch are. mounted rods 5a, 5b and 6a, 6b, according to a known method, themselves mounted on levers 7a, 7b, and 8a, 8b.
  • each half-hatch is controlled by two rods and lever, but their number is not limiting.
  • each half-hatch is mounted integrally on a control shaft 9, 10, horizontal and parallel to the axis of the wagon. These two parallel shafts are driven at 1 and 12 by means of a transverse shaft 13 controlled by a flywheel 14 at each end. The drive of the shafts 9 and 10 taking place by any known device from the shaft 13.
  • the links 5a, 5b have at their end connected to the lever, a longitudinal window 15 in which the axis 20 of the lever connection moves during the first opening phase ( Figure 2).
  • the links 6a, 6b do not include such a window; they are articulated in 16 without significant play.
  • the length of the window determining the extent of the offset at the opening corresponds to the width of the opening made by the half-hatch 4, as illustrated in FIG. 2.
  • FIG. 3 illustrates the complete opening of the half-doors 3 and 4 under the action of the steering wheel 14.
  • the hatches can be of width I 1 , I 2 identical but a preferred arrangement comprises half-hatches of different widths, the smallest hatch 3 being connected to the rods comprising the window, the difference (1 2 - 1 1 ) being equal to the length of window 15. In this arrangement, the total length (half-hatch + blellette) is identical on each side of the device.
  • the cross section of the hatches is generally rectangular, but a preferred arrangement (FIG. 4) gives the first moving hatch 4 a general trapezoidal section with the largest base 17 being upwards, the faces 18, 19 of the two edges adjacent forming a dihedral open towards the bottom.
  • This arrangement allows the opening, to cause a flow avoiding arch phenomena due to symmetrical flows.
  • the invention according to the preferred arrangement has a clearance located at the outer end of the link connected to the hatch.
  • the clearance can be located elsewhere in the drive mechanism, for example at the other end of the link, on the lever 7a, in the drive link 1i of the shaft 9, or distributed on several links, the main thing being the presence in the mechanism of a significant clearance allowing a time lag of the opening of the doors.
