Definitions

  • the present invention relates to a self-propelled machine for separating solid or fibrous deposits or waste from sands and the like,which has been specifical­ly designed for cleaning beach sands.
  • the main object of the present invention is to overcome the above mentioned drawbacks,by provid­ing a self-propelled machine for cleaning beach sands which is very simple construction-wise as well as very reliable.
  • Another object of the present invention is to provide a self-propelled machine for cleaning beach sands which is specifically designed for deeply cleaning said beach sands.
  • Yet another object of the present invention is to provide such a self-propelled machine for clenaing beach sands which may be driven by a single operator.
  • a self-propelled machine for cleaning beach sands characterized in that it essntially comprises a front device for collecting loose material to be cleaned and to convey it to a screening device adapted for separating the deposits or waste from said loose material and respectively discharging the cleaned material on the ground and said deposits or waste into a collect­ing vessel,there being moreover provided means for levelling the discharged material and means for empting said collecting vessel.
  • the self-propell­ed machine for cleaning beach sands comprises a frame 1 which is mounted on wheel pairs 2 or track pairs,which are suitably driven,and is provided,at its front end portion,with a given height upright pair 3.
  • conveyor belt may be either of the blade or bucket type,as indicated at 6, and is supported,at the bottom thereof,by one or more cylinders 7 so as to be able of rotating,for a given angle,about its top axis 8,thereat it is pivoted to the uprights.
  • the conveyor belt may rotate either in a clockwise or anticlockwise direction,as it is provided with or blades or buckets respectively.
  • the loose material taken up by the conveyor belt falls on a conveyor element 10 leading to the central portion of a frustum of cone shaped portion 11 of a drum 12,having a horizontal axis,the wall of which is made of a metal net,perforated sheet metal or the like.
  • This drum is supported by a suitable frame 13 and is rotated,with a suitable angular speed,by means of a motor 14,preferably of the hydraulic type.
  • drum ends with a further frustum of cone shaped end 15 communicating,through a duct 16, with a vessel 17 and is provided,at its inner surface, with a given number of propellers,preferably made of sheet metal,18,and having a given linear extension.
  • propellers are advanta­geously arranged,with respect to a cylinder generatrix, at a slanting angle from about 30°,at the output cone 15,to about 10° at the cylindrical portion and the inlet cone 11.
  • the above-mentioned drum has a length of about twice its diameter,whereas said propellers have a height of about 1/8-1/13 their diameter,are provided in a number of 6 to 10 and have a pitch corresponding to ten diameters thereof.
  • propellers are the main feature of the sand screening machine,mainly because of to reasons: - during the operation they entrain to the top portion of the drum the loose material to be screened,by causing it to fall on the filtering underlying portion,and continuously renewing the filtering kinetic energy, mainly in the case of a wet material; - the slanted arrangement of the propellers causes said propellers to be downwardly slanted,during the raising rotation movement,toward the outlet mouth;thus the material will fall near said mouth,thereat only the material to be screened out must arrive which,owing to the greater slant of the propellers in the end cone, will exit the drum.
  • the efficiency of this screening operation will depend on a plurality of parameters, such as: - the size of the drum; - the number,height and angles of the propellers; - the size of the perforations,shape of the screening wall and perforation area/total area ratio; - the rotation speed of the drum; - the type of inlet loose material; - the type and size of the deposits or waste.
  • the operator may affect the screening out degree by suitably adjusting the rotation speed of the drum and/or the machine advancing speed and/or the conveyor belt speed.
  • the clogging of the perforated wall may be advantageously prevented,in addition to the reversing of the gravity force on the clogging elements,by rolling on the drum surface a hard bristle cylindrical brush,acting as a driven gear engaged with said drum.
  • a manifold may be provided near said perforated wall and outside of the drum,which manifold will be provided with a plurality of pressuriz­ed air ejecting nozzles,the pressurized air being supplied by an air compressor mounted on the machine.
  • the not screened residual materials will fall into the vessel 1,which may be hydraulically raised by side arm members 19 to be discharged,with the machine at rest,on a truck or the like.
  • a double articulated parallelogram structure 20 which is mounted on said raising arm members, a rod of which consists of a hydraulic jack 21 for tilting the vessel in order to discharge the collected waste material.
  • This blade in particular,may be mounted on said vessel 17,with the possibility of adjusting its working height,by means of little displacements of said vessel.
  • All the hydraulic and operating controls of the above disclosed machine are arranged in the driver's cab 24 therefrom the driver may control all of the operating steps of the machine.
  • the propelling system of the machine may comprise four driving wheels,or two tracks,preferably driven by hydraulic motors,supplied by pumps mounted on the machine internal combustion engine 25.
