Definitions

  • the present invention relates to a device for remo­ving explosive material such as old ammunition and the like from soil.
  • Such a device is used for removing explosives which have, for example, been in the ground since the last world war.
  • the object of the invention is to produce a device by means of which these explosives can be efficiently separated from the soil, and with which optimum safety for the operating personnel is ensured.
  • the device comprising: - a mobile frame containing an armoured control cab and a collection bin for the soil, said collection bin being provided with a bottom consisting of perforated plates; - disposed above the collection bin, a spray lance which is controllable from the cab and is con­nected to a water supply pipe; - a collection tank which is disposed under the perforated plates of the collection bin, and near the bottom is provided with a discharge pipe in which a discharge pump is accommodated.
  • the soil is emptied into the collection bin of the device by means of a conventional excavator which is armoured against possible explosions.
  • a power­ful jet of water is then directed on the soil with the spray lance, so that sand and mud are taken through the perforated plates to the collection tank situated underneath the collection bin.
  • Larger pieces and possible explosive objects remain behind in the collection bin and can be removed from it. Explosive objects can be recognized as such and rendered harmless.
  • the personnel are in the armoured cab of the machine and run practically no risk in the process, while still being able to have a good view of the work.
  • a spray pipe which is connected by means of a valve to the water supply pipe of the spray lance. This spray pipe is for flushing the grid and the collection bin clean.
  • one or more spray nozzles are disposed in the collec­tion tank, and are connected to the water supply pipe of the spray lance. These spray nozzles are for the purpose of maintaining water circulation when the spray lance and the spray pipe are not in operation. This prevents the discharge pump accommodated in the discharge pipe from running dry.
  • the spray nozzles are preferably connected to the water supply pipe by means of an excess pressure valve.
  • the walls of the collection bin are preferably clad on the inside with wood, so that if an explo­sion takes place, ricocheting of shell splinters and the like against the walls is avoided.
  • the wood also provides effective protection for the walls. Since the perforated plates forming the bottom of the collection bin are detachable, they can easily be replaced if damaged by any explosion.
  • the device according to the invention comprises a mobile frame which is provided with caterpillar tracks l, a control cab 2, and a collection bin 3.
  • the cab 2 is provided with panels 4 of armour-plated glass, and is designed in such a way that opera­ting personnel in it are virtually fully protected against a possible explosion.
  • the collection bin 3 is rectangular in top view, with upright walls 5, which are clad with wood on the inside, preferably with deal about 2.5 cm thick.
  • the wood cladding provides effective protection of the upright walls, on the one hand, while the ricocheting of shell splinters against the walls is avoided, on the other.
  • the bottom of the collection bin 3 consists of a grid 6, which is formed by a number of perforated plates which are disposed detachably and can thus easily be replaced in the event of damage.
  • Under the collec­tion bin 3 is a collection tank 7, which is trough-­shaped with downward-sloping side walls.
  • a discharge pipe 8 Near the bottom of the collection tank 7 is a discharge pipe 8, in which a discharge pump is accommodated, suitable for pumping a water and soil mixture, and driven by a hydraulic motor l0.
  • the discharge pipe 8 extends to the rear side of the device and a discharge pipe (not shown) can be connected to it. If the water and soil mixture has to be trans­ported over a distance of more than l km, extra pumps of the same type as pump 9 will have to be disposed in the discharge pipe.
  • the device is also provided with a water supply pipe ll which extends forwards from the rear side thereof and divides near the front of the cab 2 into a pipe l2 which leads to a spray lance l3, disposed above the collection bin 3, and an essential­ly through pipe l4.
  • the spray lance l3, which can be controlled from the cab, is of a known type and need not be described in detail here.
  • Connec­ted to the pipe l2 is a branch pipe l5, which ex­tends along the inside of the walls 5 of the collec­tion bin 3 and is provided at regular intervals with openings.
  • the pipe l5 thus forms a spray pipe for flushing away the material through the grid 6.
  • the through pipe l4 leads to a spray nozzle l6, which is provided inside the collection tank 7 under the grid 6, and the object of which will be clear in the description of the working of the device.
  • a spray nozzle l6 Disposed in the pipes l2, l5 and l4 are valves l7, l8 and l9 respectively.
  • Connected to the pipe l2 is another pipe 20 for feeding a screen washer for the windscreen of the cab.
  • the vehicle is driven by a diesel engine 2l, which also drives the hydraulic motor l0 and hydraulic pumps 22 for placing the water supplied by the pipe ll under pressure.
  • the device according to the invention works as follows:
  • Ground in which possibly explosive objects could be present is excavated using a conventional ex­cavator, which is provided with suitable safety facilities, and is emptied into the collection bin 3.
  • a conventional ex­cavator which is provided with suitable safety facilities, and is emptied into the collection bin 3.
  • a powerful jet of water is directed onto the soil in the bin 3, so that sand and mud and other small particles are flushed away through the grid 6 to the collec­tion tank 7.
  • the large parts and possibly explo­sive objects remain sprayed clean on the grid 6. Any explosives can be recognized as such and rende­red harmless.
  • the collection bin 3 is then emptied, and a new load of soil is emptied into the collec­tion bin 3.
