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 chute to a spreading plate arranged at the rear, a device being provided which independently of the spreading distance of the spreading material thrown from the spreading plate the loading of the gritting vehicle or the filling of the silo container keeps essentially constant.
  • EP-A-0071291 which discloses a spreading vehicle according to the preamble of claim 1, to solve this problem it is proposed to mount the spreading plate on a trolley which is pulled behind the spreading vehicle. As a result, the spreading disc is supported on the road surface. Regardless of the loading of the silo container and the deflection of the vehicle body, the spreading disc should always be kept at the same distance above the road surface in this way.
  • the generic spreading vehicle constructed in this way is however unusable for practical use; because on the one hand the trolley performs uncontrolled vertical and roll movements due to unevenness in the road to be sprinkled, and on the other hand obstacles of even low heights cannot be passed with the generic spreading vehicle without that there is a risk that the support of the trolley equipped with the support wheel breaks off. The latter is particularly true when reversing.
  • the present invention has for its object to provide a spreading vehicle of the generic type, in which the spreading width can be kept approximately constant during operation even with changing loads, which is suitable for practical use.
  • This approach ensures an automatic adaptation of the dropping conditions from the spreading disc, which is also suitable for practical use, in such a way that an approximately constant spreading width can be maintained regardless of the change in the loading of the spreading vehicle.
  • the spreading width is kept constant according to the invention despite increasing lifting of the spreading plate 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 prerequisite of the teaching according to the invention is the ongoing and automatic determination of a measured variable, preferably proportional to the increasing emptying of the grit container, preferably the distance between the grit plate and the ground or grit plate and 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, namely the speed 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 can either be with a mechanical probe or without contact, e.g. using ultrasound, sonar, laser beam or the like.
  • the ongoing measurement of the loading or unloading state of the silo container can, for. B. 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, i. H. it is ensured that the spreading density does not decrease with increasing emptying of the grit 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 thereby a reduction 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 deflection of the loading platform (1) is generated.
  • a first alternative for measuring the platform height is an electronic measuring device (10), which measures the distance from the floor (9) z. B. 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 spreading disc While the normal discharge height of the spreading disc (6) is set at around 30 cm when the silo container (3) is fully loaded, the spreading disc can be raised by approx. 15 to 20 cm during operation as it is discharged. In the horizontal direction, without the device according to the invention, this would mean an undesirable increase in the originally set maximum spreading width from approx. 3 m to approx. 4 m.
  • the device provided according to the invention keeps the spreading width constant in that the speed of the spreading disc (6) decreases in accordance with the relief of the spreading vehicle.
