Detailed Description of Figures
With reference to the figures there is shown a device 99 for reducing dust spread at an excavator arm 105, generally comprising a flexible hose 7 providing a fluid pathway with an associated fluid pumping means 3, the hose adapted to be secured along the excavator arm, the fluid pathway having a plurality of fluid dispensing outlets 4,5 at a distal end, the outlets adapted to supply fluid in more than one state, and a fluid reservoir at a proximal end, wherein the fluid reservoir comprises a displaceable container 1 arranged to be attached to a mount 2, said mount arranged to be bolted to the step 200 of the excavator 100.
In particular reference to the pictured embodiment the embodirnent comprises a plurality of parts, as shown in Figure 4, which may be installed on an excavator, as shown in the configuration shown in Figure 5.
When installed on the excavator the device comprises fluid outlets located in use at the excavator arm, wherein the reservoir is detachably located at the step of the excavator.
In between the outlets and the reservoir there is provided an elongated flexible piping. This piping may be envisaged to be provided in a plastics or polymer.
The piping is clipped by clips 6 to the excavator in a plurality of locaticns, and in use may be envisaged to be clipped as appropriate according to user preference ancior mode of the excavator.
The mount 2 piovides a fixec location for the reservoir, allowing the -eservoir to be displaced for filling or maintenance purposes.
Add lonally the mount provides and locates the pumping means 3, which the reservoir 10 is ditctly connected to by a feed 31.
The piping 7 is thereby permanently connected to the pumping means 3, so as to advantageously avoid damage in use from repeated connections and disconnections of the container 1.
The feed 31 extends from ald comprises a threaded cap 10. The cap is a large diameter and the feed extends centrally therefrom. In:his way the cap may be easily removed from:he reservoir with the thread, and the container formirg the resernir may oe displaced for filling purposes, leaving the cap and feed comected to Me pumping means.
The reservoir comprises a cuboid tank container, with a topmost cap in use.
The container is strapped to the mount with two webbing straps 11 in use, which straps 25 inch-de ratchets 12, and end hooks 13. The hooks are hooked into lanyard attachment points on the mount The mount comprises a shelf for the container to be strapped to from above, wherein the pumping means is located and mounted below the shelf.
