Abstract
ABSTRACT OF THE DISCLOSURE
There is provided a cleaning unit for road cleaning vehicles in particular for collecting animal excrements on the open road and specifically from sidewalks. The unit comprises both at least one liquid feed means and aspiration means thereby producing moist col-lecting through aspersion and aspiration. The aspersion liquid can be admixed with a quantity of a hardening substance such that the moist collecting of excrements is produced without liquefying of already dis-persed excrements but by obtaining almost instantaneous hardening thereof. It can also comprise means for breaking up solid excrements said means being for example a rotary knife.

Description
12372Si7 This invention relates to a cleaning unit for road cleaning vehicles to permit especially the collecting of animal excrements on the open road and particularly from sidewalks.
~rhere are known road cleaning vehicles for collecting excrements of animals~ which comprise a container with a brush which is lowered down to the collection level and substantially comprises a rotary brush.
There are known moreover road cleaning vehicles in which the rotary brush is combined with washing water spraying.
Anyhow, the brush collecting vehicles and devices have the major ~ disadvantage of being quickly soiled and of expanding the excremen-tial products rather than efficiently collecting the latter.
The gathering is obviously increasingly difficult where the excremen-tial product is of a dispersed nature (droppings). Reversely, when the excremential product is of an excessively solid nature (solid dung), the collecting device can be clogged up by accumulation thereof.
This invention remedies these disadvantages and its object is a cleaning unit characterized in that it both comPrises at least one liquid conveying means and a suction means thereby providing moist col-lecting through aspersion and aspiration.
In accordance with this invention the spraying liquid (generally water) can be admixed with a certain quantity of a hardening substance such that moist collecting is provided without liquefying the already dispersed excrements (droppings) but by producing almost instantaneous hardening thereof.
The unit for cleaning by moist collecting according to the inven-tion can also comprise means for breaking up solid excrements (solid dung), which can be a rotary knife thereby preventing any clogging up of the suction means and providing moist collecting through aspersion, breaking up and aspiration.
A cleaning unit according to the invention is advantageously equipped with a motor and the object of the invention is therefore also road clean-ing vehicles provided with a device according to the invention.
Other characteristics and advantages of this invention will appear from the following description which is made with reference to the attached drawings in which :
,~
~7;2~7 l - figure 1 is a perspective view of a moist collecting cleaning unit according to the invention;
- figure 2 is a top view of a sucking pan which is preferably connected to the cleaning unit through a supple sheathed tube;
- figure 3 is a lateral elevational view of such sucking pan;
- figure 4 is a partial lateral elevational view of one side of a motorized tricycle equipped according to the invention but without the wheel and fork assembly;
- figure 5 is a still simpler elevational view of such motorized tricycle from its other side.
In the form of embodiment shown in the drawings a moist collecting aspiration and cleaning unit generally comprises an aspiration turbine 1, a sucking pan 2, a casing 3 for collecting excrements, an aspersion nozzle 4 opening into the sucking pan, a liquid tank 5 and a pump 6.
The cleaning unit is completed by a rotary knife 7 and a driving motor 8.
The turbine 1 and the sucking pan 2 are connected to the casîng 3 through supple sheathed aspiration tubes A; the aspersion nozzle 4 is connected to the pump 6 through a supple conduit E (the spraying liquid being preferably but not exclusively water); the rotary knife 7 is connected to the electric driving motor 8 through a flexible trans-mission means T. It will be understood that control means (not shown) is adapted to act upon the water feed and/or the knife drive.
In figure 1 an assembly comprising a sucking pan 2, a tube A, a conduit E and transmission means T is shown entirely and a second as-sembly is shown partly; the cleaning unit according to the invention can be equipped with two aspiration, aspersion and breaking up assemblies.
The sucking pan 2 can comprise both a collecting edge portion 2A
in the same way as in the usual pan and a raised abutment edge 2B; it can also be provided with an admittance cover 2C.
The shape of the knife may be that of a lying U, both ends of which are mounted on a common geometric vertical axis X.
The liquid preferentially water contained in the tank 5 can be admixed with a certain quantjty of hardening substance which depending on its nature permits almost instantaneous transformation of a dispersed excrement 1237s~S7 1 (droppings) to a solid product.
The already solid products as hardened products are easily broken up through the rotary knife 7 and the whole of the fragments can be easily sucked up to the collecting casing 3 without any risk of clog-ging up the sucking pan, the aspiration tube A as well as the hollow handle 9 that may connect the sucking pan 2 to the aspiration tube A.
The handle 9 can be used for example as a vacuum cleaner handle by the operator sitting on the seat 10 of the motorized tricycle (im-mobilized or running) provided with the unit according to the invention.
Such handle can take a socalled "folding up position" by means of any appropriate device when it is not in use.
A portion of such unit is shown in figure 4 as mounted in a protec-tive decorative housing 11.
The two-level aspiration turbine 1 is driven by a control system having power take off 12 from motor M of the vehicle, a belt 13 and a declutching device 14.
The belt 13 can be mounted about a pulley 15 to drive the eiectric generator starter device 16 of the motorized tricycle.
The moist collecting cleaning unit acting through aspersion, break-ing up and aspiration can have an independent electric power supply and comprise to this end for example a storage battery (not shown) with its regulator.
The collecting casing 3 may comprise a recovery container (not shown) for emptying it readily after the cleaning unit according to the inven-tion was operated for a certain time period.
Finally, it will be understood that this invention was only described and represented by way of a preferential exemplifying form of embodiment and that equivalent parts can be substituted for its constituents without departing from the scope of the invention as defined in the appended 3 claims.
