Thanks to this arrangement, the conveyor belts 16 and 17 are driven to scroll in the direction of the arrows (FIG. 1).
  • a pinion 48 which drives a chain 49 driving a pinion 50 wedged on a roller 51 for driving the conveyor belt 18.
  • the conveyor belt 18 has edges 52, the belts 16 and 17 may also have edges, these are not shown in the figures.
  • the frame 15 also supports an apron 60 formed by a generally rectangular frame with two sides 61 and 62 two cross members 63 and 64 and an intermediate side 65.
  • the sides 61 and 62 are connected by a motor shaft 67 on which is pinched a pinion 70 cooperating with a chain 71 meshing with a pinion 72 propped up on a shaft 73 on which is pinned a pinion 74 driven by a chain 75 engaged with a pinion 76 of a second outlet from the housing 41.
  • a grid conveyor 81 is guided on the two pinions 78 located between the side 61 and the crosspiece 65 and the two corresponding pinions 79.
  • An identical conveyor 81 is guided between the side 62 and the crosspiece 65 on the pinions 79 and 78.
  • the two conveyors 81 are formed by bars 82 extending in parallel and connected by a flexible link or links 84. At regular intervals the bars are integral with L-shaped profiles 83.
  • idler gears 85 which have the general shape of an equilateral triangle, the teeth being intended to cooperate with the bars 82.
  • the shaft 67 is guided in bearings 88 of the frame 15 and between the sides 61 and 62 are inserted jacks 90 which make it possible to tilt the deck 60 around the axis 67 so as to be able to lower or raise it at will. said apron 60.
  • the sides 61 and 62 are integral with pads 92 preferably supported by jacks 93.
  • the apron 60 is integral with a blade 95, while in front of this blade extend feelers 96 carried by a bar 97 supported by said apron.
  • the feelers 96 are constituted here by elastic bars which are connected to a signaling member if during the work of the machine they bend beyond a certain position. These feelers 96 therefore make it possible to detect rocks in order to prevent the blade 95 from encountering them, which would risk damaging the machine.
  • the signaling system can be visual, acoustic or directly connected to the machine in order to block it. It could also be provided that said system acts directly on the jacks 90 and controls the instantaneous lifting of the deck 60 if a rock is detected by the feelers 96.
  • the signaling system is not shown here in detail.
  • a pulley 100 which drives by a crossed belt 101 a pulley 102 wedged on an axis 103 guided in bearings on the sides 61 and 62, said axis comprising at regular intervals turnstiles 105 formed by radial arms 104 provided at their free end with pallets 106 made of flexible and elastic material, the latter coming flush with the bars 82 of the conveyors 81.
  • the machine according to the invention is more particularly intended for cleaning beaches.
  • the machine moves on the beach to be cleaned, the blade being driven into the sand at a certain depth regulated by the pads 92 and the jacks 90.
  • the sand arrives on the conveyors 81 which are driven by the pinions 78, the sand falls back to through the intervals of the bars 82, while the algae and other detritus are entrained by the sections 83.
  • the turnstiles 105, by the pallets 106 strike said detritus to rid them of the sand which adheres to it and this action is reinforced by the shaking of the carriers 81, shaking generated by the pinions 95, the teeth of which cooperating with the bars 82 tend to raise and lower said bars 82.
  • the rake 10 makes it possible to level the ground, while the ramp can spray a disinfectant or other liquid, this being contained in the reservoir 13.
  • the apron 60 When the bucket 7 is full, the apron 60 is raised and the machine is taken to a landfill where the bucket is emptied.
  • the sides 61 and 62 each have, at an intermediate point of their length, a tab 115 which supports an axis 116 secured to a frame comprising two cheeks 117 and 118 connected by two shafts 119 and 120.
  • pinions 121 and 122 On the shaft 119 are wedged, at each end of the pinions 121, while on the shaft 120 are wedged two pinions 122. On the shaft 120 is wedged a pinion 125 which cooperates with a chain 126 driven by a pinion 127 wedged on the output shaft of an engine 128 carried by a cradle 130 secured to the cheek 118.
  • the pinions 121 and 122 have large teeth for driving a transporter 131 formed of guilles 132 connected together by flexible bands 133.
  • Some bars 81 may include profiles 138 made, for example, of a flexible and elastic material.
  • the motor 128 drives the transporter 131 at the same speed as that of the transporter 81, but in the opposite direction (see the arrows in FIG. 6).
  • the trash and heavier objects which would tend to slide on the blade 95 are pushed by the conveyor 131 towards the conveyor 81. If an object too important comes to be inserted between the blade 95 and the conveyor 131 this one rocks around of the axis 116 so that all blocking of the machine and possible deterioration of the grid conveyors 131 are thus avoided.
  • the invention provides for carrying the conveyor 81 by mounting a screen 143 thereon.
  • the grid 143 is directly produced on the bars which make up the conveyor as is clearly seen in FIG. 8; said mesh comprising a first metal wire 140 folded in a zigzag, to form meshes, passing over two adjacent bars 142, 144, a second metal wire 141 folded in a zigzag on two adjacent bars 144, 146, one of which receives the 144 wire 140, wire 141 being folded to pass between the branches of a fold passing over the bar 144 and so on.
  • Such an arrangement makes it possible to have a flexible transporter.
