Description

This addition aims at improvements

  with the self-propelled machine described in the main patent.

  The main patent concerns an automatic machine

  trice for beach cleaning consisting of a self-propelled machine supporting a tilting bucket and with, at the front, means for picking up litter from the sand and a conveyor belt for conveying the litter picked up in the bucket, the means for picking up rubbish on the sand comprising an apron mounted pivoting on an axis perpendicular to the longitudinal axis of the machine, means being provided for controlling the adjustment of the inclination

  said apron, the latter comprising, at its anterior end

  rieur, a blade intended to engage in the ground and behind this, a carrier with grids emerging

  on the conveyor belt and driven by motor means.

  Such a machine has the disadvantage of not always allowing the picking up of heavy or bulky objects.

  A first object of the invention is to perfect-

  ner the machine according to the main patent to remedy

to this disadvantage.

  The machine according to the invention is of the type cons-

  with a self-propelled machine supporting a tipping skip-

  and with, at the front, means for picking up detri-

  you are on the sand and a conveyor belt to carry

  the rubbish picked up in the bucket, the means for collecting it-

  serve as rubbish on the sand comprising an apron pivotally mounted on an axis perpendicular to the longitudinal axis

  of the machine, means being provided for controlling the regulation

  ge of the inclination of said deck, the latter comprising, at its front end, a blade intended to engage in the ground and behind it, a grid conveyor opening onto the conveyor belt and driven by motor means and is characterized in that it

  has a second trans-

  grid carrier mounted by its tilting upper end

  lant on an axis perpendicular to the direction of advance of the machine and whose lower end located above the blade rests on stops provided on the latter, the second conveyor with grids being driven by a motor in one direction opposite to that of the transporter

with apron grilles.

  Thanks to this arrangement, litter is

  pushed by the second grid conveyor towards the first

  mier conveyor with grids and driven by the latter towards the conveyor belt. The second grid conveyor

  can be lifted which eliminates the risk of damage

  tion of the latter, if a heavy and bulky object is

lifted by the blade.

  Preferably, some of the bars are

  killing the second grid conveyor has pro-

flexible and elastic yarns.

  In some cases - you may need to remove

  another object of the invention is to allow such elimination. In this

  Indeed, the machine comprises, directly mounted on the trans-

  apron grid carrier, a mesh.

  The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which: Figure 1 is a perspective view showing

the machine deck.

  Figure 2 is a sectional view along the line

II-II of Figure 1.

  Figure 3 shows a detail of modification of the

grid conveyor.

  Figure 1 shows in perspective the deck with its sides 61 and 62 and the blade 95 at its front end. The sides 61 and 62 each comprise at an intermediate point of their length a tab 115 which supports an axis 116 integral with a frame comprising two cheeks 117

  and 118 connected by two trees 119 and 120.

  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 a motor 128 carried by a cradle 130 secured to the cheek 118. The pinions 121 and

  122 have large teeth to carry a

  unit 131 formed of grids 132 connected together by

flexible bands 133.

  Cheeks 117 and 118 in the vicinity of their ex-

  lower end rest on stops respectively, 136 secured to the upper end of the blade 95. Some bars 81 may include profiles 138 made, for example, of a flexible material

and elastic.

  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. 1). Thus, 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 axis 116 so that we avoid

  thus any blockage of the machine and a possible deterioration

  ration of grid conveyors 131.

  It is possible to provide inserted between the side 61 and the cheek 117, a jack 137 making it possible to lift the second conveyor with grids 131 to facilitate the release

  a trash which would be trapped between the two transport-

grid tutors 81 and 131.

  In some cases, we may have to clean

  beaches that are covered with litter of small di-

  mensions. As the grids of the conveyor 81 provide significant intervals between them, the removal of

  these little trash is impossible.

  To allow such cleaning, the invention

  plans to carry carrier 81 by climbing on it

here a grid 143.

  - So that the transporter can nevertheless operate

  normally work, the wire mesh 143 is directly

  dried on the bars that make up the transporter like this

  clearly seen in Figure 3; said mesh includes

  nant a first metal wire 140 folded in a zigzag to form meshes, passing over two adjacent bars 142, 144, a second metal wire 141 bent in a zigzag on two adjacent bars 144, 146, one of which receives the 144

  wire 140, wire 141 being bent to pass between the branches

  ches of a fold passing over the bar 144 and so on.

  Such an arrangement makes it possible to have a flexible conveyor. Of course, the invention is not limited

  to the embodiment which has just been described and represented

  you. Many modifications can be made

  detail without departing from the scope of the invention.
