Description

  The subject of the present invention is a vehicle for scanning

  self-loading streets with a trans-

  carrying detritus from the surface that supports them to the inside

  of a collection bucket equipped with a deflector which discharges them obliquely.

  in said bucket at their exit from the suction duct; downstream

  said deflector the upper part of the dumpster

  tritus being connected to a radial centrifugal fan.

  In achievements of this type known so far, the de-

  flector abruptly ends at its lower end. The finding

  tation which is the basis of the present invention makes it possible to establish that the air is brewed, in an oblique direction, downwards, as far as the tank as in a vortex formed by the detritus

  disaggregated and water spray. This is how dirty water can

  can be rejected upwards, which causes the expulsion of polluted air as a result of the formation of this vortex. These disadvantages are further increased when, in addition, water is injected into the

  suction line, in order to better separate and remove from the air

  In order to avoid these drawbacks, the present invention aims to improve the separation between the soiled particles of the detritus and the air which conveys them and to obtain, downstream from the extreme edge of the deflector. The present invention responds to this object in that the end edge of the baffle is bent upwardly so that the air introduced along with the debris is deflected by a deflector. area

  who guides it without the detritus themselves being at the same time

  In the case of the present invention, because of the curvature

  existing at the end of the deflector, there is a depression that de-

  the flow of air, without preventing the soiled particles from continuing their downward trajectory because of their inertia. The

  rubbish is therefore transported inside the bucket, but in

  the flow of air, even before being evacuated out of the bucket, is

  led to the top of it in a pipe connected to the

  This results in a much safer separation between soiled particles and air, as well as a peaceful air outlet movement;

  the rise of dirty water in the fan is thus avoided.

  The application of the aerodynamic rules in the configuration of the free edge of the deflector, in the context of the present invention, allows

  by means of a technical effort whose modestness is easily conceivable,

  to obtain considerable advantages for the object of the invention.

  An exemplary embodiment of the invention is shown diagrammatically

  The street sweeping vehicle represented in its complete form consists essentially of a chassis comprising the driver's cab 1 and a refuse collection bucket.

  of a suction pipe 3 the detritus picked up by the broom 4 are

  street surveys by suction through the pipe 3- (shown in gray) assisted by the air blown into the pipe 5., which emerges flush

  from the ground near the suction line 3. And the detritus

  aspirated are brought to the opening 10 of the suction duct 3 which de-

  mouth in the collection bin 2. Thus, the swirl of air, in

  same time as the detritus, is deflected by the oblique deflector 11 dis-

  placed on the upper panel of the trash collection bucket 2 which deflector 11 has a rounded shape 13. The detritus are, by their own inertia, projected obliquely downwards, and the air stream thus released detritus escapes through the grid 8, which is at the top of the trash collection bucket, for

  be led to the fan 9 connected to the blower duct 5.

  In order for the separation of air and detritus to be carried out

  the best way possible, the free edge 12 of the deflector 11 is

  bent upwards so that the air mixed with the detritus is deflected, as it were, by a surface that would guide it, in the direction of the three arrows represented, without

  that the detritus themselves be carried away.

  The present invention can be used for the construction of public cleaning bins that provide more efficient cleaning in

  at the same time that it avoids the release of air polluted by

  tritus from which they are purged by means of the device

this invention.

Claims (1)

CLAIM   Auto-loading street sweeping vehicle   having a suction duct carrying the detritus from the overhead   face that carries them to the inside of a collection and collection bucket   carrying a deflector which projects said detritus obliquely into the bucket as soon as they exit the suction duct; downstream of said deflector   the upper part of the refuse collection bucket being connected to   to a radial centrifugal fan, characterized in that the free edge (12) of said baffle (1 1) is bent upwards, so that the air mixed with the refuse is discharged as by a surface which   would guide him, without the rubbish themselves being carried away.
