Definitions

  • the invention relates to a spreading vehicle with a spreading device built on a loading platform, in particular a silo spreading device, in which the spreading material is automatically removed from a silo container and fed via a discharge channel to a spreading plate arranged at the rear, which is attached to the discharge channel.
  • the problem arises that with increasing emptying of the loading platform or the silo container, the deflection of the vehicle frame with respect to the wheel axles becomes smaller, so that the spreading plate assumes an increasingly distant position from the ground in accordance with the relief of the vehicle.
  • the spreading material thrown off the spreading plate only appears on the ground at a greater distance from the spreading plate.
  • the value is e.g. 3 m - this means at least on narrow roads that with increasing relief of the spreading vehicle, vehicles parked on the side are hit by the spreading material.
  • the driver has no way of avoiding this disadvantage, since he cannot be expected to continuously readjust the spreading device under the conditions of road traffic.
  • the present invention has for its object to provide a gritting vehicle of the generic type to be equipped in such a way that the spread can be kept approximately constant during operation.
  • this object is achieved by an automatically operating device which keeps the throwing distance of the spreading material thrown by the spreading disc essentially constant regardless of the loading of the spreading vehicle or the filling of the silo container.
  • the device is a measuring device for measuring the distance between the spreading device and the ground or the wheel axis of the spreading vehicle and in the other case a measuring device for measuring the loading of the vehicle or the filling of the Contains silo.
  • Both solutions ensure an automatic adjustment of the dropping conditions from the spreading disc, such that an approximately constant spreading width can be maintained regardless of the change in the loading of the spreading vehicle.
  • the spreading disc is used with increasing relief of the of the gritting vehicle increasingly approaching the ground, ie lowered relative to the vehicle axles. This lowering movement compensates for the increasing rebound of the vehicle.
  • the spreading width is kept constant in spite of the increasing spreading plate being raised relative to the ground in that the speed of the spreading plate decreases accordingly, the centrifugal forces acting on the spreading material being reduced.
  • Another essential requirement of the teaching according to the invention is the ongoing and automatic determination of a measurement variable proportional to the increasing emptying of the grit container, preferably the distance between the grit plate and the ground or grit plate and the vehicle axle.
  • a control signal is generated via a control device, to the input of which the measurement signal is connected, with which a control variable, preferably either the speed or the altitude of the spreading disc, is changed in the sense of a reduction.
  • the distance measurement can be carried out in the context of the invention by means of a measuring device which either works with a mechanical probe or without contact, for example by means of ultrasound, echo sounder, laser beam or the like.
  • the ongoing measurement of the loading or unloading state of the silo container can e.g. by more or less deeply immersed in the grit, by measuring the vibration amplitudes of the loading platform or - particularly simply - by counting the number of revolutions of the screw conveyor, taking into account the initial filling level of the silo container.
  • the invention achieves a constant spreading density, ie it is ensured that the spreading density does not decrease with increasing emptying of the spreading material container. Increasing the spreading plate and the associated increase in the spreading width with a constant supply quantity would otherwise result in an increase in the spreading area and thus a decrease in the spreading density per m2.
  • the constant spreading width achieved according to the invention is a very significant advantage under the current spreading requirements because it opens up the possibility of setting the spreading density to a minimum without fear of it being undershot.
  • Fig. 1 two alternative measuring devices are each shown schematically, with which an output signal corresponding to the spring deflection of the loading platform (1) is generated, which is converted into a control signal for adjusting the length of the telescopic holder (7) by means of a control device (not shown).
  • a first alternative for measuring the platform height is an electronic measuring device (10) which measures the distance from the floor (9), for example by means of a laser beam (11).
  • a second alternative is a mechanical measuring device (12) which measures the change in distance between the loading platform (1) and the vehicle axle (2) by means of a feeler lever (13) which is articulated on the differential housing (14).
  • both types of measuring devices require damping or smoothing in such a way that vibrations of the vehicle body due to bumps on uneven road surfaces are suppressed.
  • the normal discharge height of the spreading plate (6) is set at about 30 cm when the silo container (3) is fully loaded, it can increase in operation with its increasing discharge without the device according to the invention by about 15 to 20 cm come. In the horizontal direction, this means an undesired increase in the originally set maximum spreading width from approx. 3 m to approx. 4 m.
  • the device according to the invention succeeds in keeping the spreading disc (6) unchanged in its initially set height above the ground during the entire spreading operation.
  • the set height depends on the desired spreading distance of the spreading material. This is a function not only of the height of the spreading disc above the ground but also of the speed of the spreading disc.
