FR2534291A1 - UNIT FOR COLLECTING EXCREMENTS OF ANIMALS ON THE PUBLIC ROAD AND VEHICLES EQUIPPED WITH THIS UNIT - Google Patents

Abstract

THE INVENTION RELATES TO A CLEANING UNIT FOR ROAD VEHICLES ALLOWING IN PARTICULAR PICKUP OF ANIMAL EXCREMENTS ON PUBLIC ROADS AND IN PARTICULAR ON SIDEWALKS. IT INCLUDES BOTH AT LEAST ONE 5-6-E-4 LIQUID ADDUCTION MEANS AND 1-A-3-A-2 SUCTION MEANS OR WET PICKUP BY SPRAY-SUCTION. THE SPRAYING LIQUID MAY BE ADDED TO A CERTAIN QUANTITY OF A CURING SUBSTANCE SO THAT THE WET PICKUP IS OBTAINED WITHOUT LIQUEFIING THE EXCREMENTS ALREADY DISPERSED BUT OBTAINING THEIR QUASI INSTANT CURING. IT MAY ALSO INCLUDE A MEANS OF FRACTIONING THE SOLID EXCREMENTS, THIS MEANS CAN BE A ROTARY KNIFE 7. THE INVENTION APPLIES GENERALLY TO ROAD VEHICLES.

Description

The present invention relates to a cleaning unit for vehicles

  of roads allowing in particular the collection of the excrements of animals on the public road

  and especially on the sidewalks.

  There are public vehicles for the collection of animal excrements, which include a brush box which is lowered at the pickup and

  which essentially comprises a rotary brush.

  Also known road vehicles combining the rotating brush spray washing water. In any case, vehicles and brush picking devices have the major disadvantage of getting dirty quickly and spreading the excremental products rather

than to pick them up effectively.

  Collecting is of course all the more difficult as the nature of the excremental product is dispersed (droppings) Conversely, when the excremental product is too solid (turd), the collection device can

become clogged by accumulation.

  The present invention overcomes these drawbacks

  and aims at a cleaning unit characterized in that it comprises both at least one means for supplying liquid and a suction means of o a wet pickup

by suction-spray.

  In accordance with the invention, the spraying liquid (generally water) may be supplemented with a certain amount of a hardening substance so that wet picking is obtained without liquefying the already dispersed excrements ( dung) but by obtaining their

almost instantaneous hardening.

  The cleaning unit according to the invention by wet pick-up may also comprise a means of fractionation of the solid excrement (turds), this means being able to be a rotary knife, hence the impossibility of an obstruction of the suction means and a wet pickup

  by spray-fractionation-suction.

  The cleaning unit according to the invention is advantageously motorized and the invention therefore also aims to

  the road vehicles equipped according to the invention.

  Other features and benefits of

  the present invention will emerge from the description which will

  3. In the illustrated embodiment, a suction wet cleaning unit generally comprises a suction turbine (1), a suction shovel (2), a housing (3) for collecting excreta, a spraying nozzle (4) opening into the shovel, a liquid reservoir (5) and a pump (6), the cleaning unit is completed by a

  rotary knife (7) and a drive motor (8).

  The turbine (1) and the suction shovel- (2) are

  connected to the casing (3) by flexible suction ducts

  tion (A); the spray nozzle (4) is connected to the pump (6) by a flexible duct (E) (the watering liquid is preferably, but not exclusively, water); the

  rotary knife (7) is connected to the electric drive motor.

  (8) by a flexible transmission (T) Of course, a command (not shown) can act on the arrival

  of water and / or on the entralnement of the knife.

  In FIG. 1, a shovel-suction assembly (2), tube (A), duct (E) and transmission (T) is represented

  in whole and a second set is shown partially

  the cleaning unit according to the invention can be

  equipped with two sets of suction-spray and frac-

tioning.

  The shovel-suction machine (2) may have a pickup edge (2A), for example, with a conventional shovel and a raised edge (2B), and may also be provided with a

access cover (2 C).

  The shape of the knife can be that of a "U" lying whose two ends are matted along an axis

common vertical geometric "X".

  The liquid, and preferably the water, contained in the reservoir (5) may be supplemented with a certain quantity of a hardening substance which, according to its nature, allows the quasi-instantaneous transformation of a

  scattered excrement (droppings) into a solid product.

  Already solid products such as hardened products are easily split by the rotary knife (7) and all the fragments can be easily sucked up to the collector housing (3), without risk of obstruction of the suction cup, tube of suction (A) as the hollow handle (8) which can connect the excavator-sucker (2) to

suction tube (A).

  The handle (9) can be used as an example of a vacuum handle by the operator sitting on the seat (10) of the motorcycle-tricycle (immobilized or in motion) equipped with the unit according to the invention handle is likely to occupy a so-called storage position "by

  any appropriate means during non-use.

  Part of this unit is represented

  in FIG. 4 mounted in a protective casing and

deliverer (11).

  The two-stage suction turbine (1) is driven by a PTO drive (12) on the vehicle engine (M), belt <13) and

disengaging device (14).

  The belt (13) can close around a pulley (15) for driving the device

  starter-dynamo (16) of the motorcycle.

  The wet-suction-fractionating suction cleaning unit may comprise its autonomous source of electrical energy and for this purpose may for example include a battery (not shown) with regulator. The collector housing (3) can contain a recovery tank (not shown) to 5. empty it easily after a certain time-operation of the cleaning unit according to the inventiono It is, of course, finally that the present invention has been described and shown only as a preferred example and that equivalences may be provided in its constituent elements without, for

  as much, go beyond the scope of the invention.
