Address : 12 Yeadon Court, Kingston Park, Kenton Bank Foot, Newcastle upon Tyne NE3 2XD: and Spylo Cottage, Bilion Bank, Lesbury, Northumberland.
Title : Improvements relating to rotary devices for cleaning conveyor belts ABSTRACT
A device for cleaning a conveyor belt comprises a rotatable annular scraper blade disposed below the belt, and inclined slightly to the plane of the belt so that one edge of the blade scrapes against the belt. The scraper is mounted on a carriage with side members having slots therein for adjustment of the position of the scraper relative to the belt and a worm device is disclosed for retrieving scraped material from below the scraper.

Description
lO~ S~
This inve~ltioll rel~tes to iml~rovemerlts in rotary devices for cl~all.i.n~1 conveyor l)elts.
Durin~ tlle ilandlin(J and conveying of minerals, rock, ash and other lriable materials, the inherent and created ,dust can cause a health hazard when the fine particles are ~blown into tl~e atmosphere where it can affect the respiratory organs of people working in the immediate locality. In the case of the larger particles of dust, I they can cause an environmental nuisance when they fall to 1~ I the floor and obscure walkways and obstacles etcO thereby~
~leading to accidents.
In order to overcome these forms of pollution, it is . I usual for the mineral to be sprayed by jets of water both before and during the early stages of transportation so _ 15 that the movement and transfers of the mineral from one . location to another will reduce this dust hazard to a .~ minimumO
~here the transporting medium is a conveyor belt made of a rubber, plastic or neoprene substance, the effect of this wetting solution to overcome the dust problem, in turn creates another problem. A certain amount of the wet dust adheres to the surface of the carrying belt and is eventually taken by the return belt into the conveyor . drive system of frictional rollers thereby causing the - 25 coefficient of friction to be reduced with the effect that the belting will slip and the efficiency of the conveyor ;
will be i~Ya ired. In an endeavour to overcome this problem of belt slip, the tension of the belt may be increased but this in turn can lead to belt breakages due~
- 30 to the high tensions involved.

A~kiitiollal ~-)roblems associate~ Wlt~) we~ st cl~hering to tlle surl~ace o~~ the return conveyor belt i~ that, a~ it dries out, the dust is deposited on the idler rollers and Ireturn drums ol~ the conveyor. ~houl~ the mineral being Icarried by the conveyor be coal, such accumulated deposits Ican create an explosive situation, so requiring the ¦employment of workmen ro remove these deposits.
Where the dust is wet, these agglomerations cause l!the steel conveyor structure to corrode and deteriorate '¦much faster than would have been the case if the dust had been removed. In a similar manner, the abrasive nature of llmany mineral dusts can reduce the working life of the ¦¦conveyor belting and so increase the costs of material l handling.
15 ¦ The present invention relates to devices for cleaning adhering dirt and dust from the surfaces of flexible conveyor belting and has for an object an improvement therein such that undue frictional contact pressure between a scraper and the said belt is not necessary,~the belt is 2f~ effectively cleaned across its full width and no power supply is needed to activate cleaning agencies; such a device will prolong the working life of the belt and reduce maintenance costs of the conveying system, there~y allowing economic savings to be achieved.
A secondary object of the present invention is to provide apparatus for handling conveyor transported ¦ materials in the zone of transfer of the material from a conveyor to some other transporting mechanism or to store, wherein material, particularly pulvurent, wet or slurried material which adhe es to the conveyor after the bulk of ' 10~

Accordinl to the invention, a convey~)r belt cleaning .device for flexible conveyor belts, comprises a frame which is capable of beinl attached to the rigid structure of a conveyor installation and is adjustable in the hori~ontal and vertical planes relative to the conveyor Ibelt, within this frame there being located a further lC) jframe or beam which can be adjustea laterally to ensure ~correct aliynment with the conveyor belt, and attached to ¦¦said beam a bearing within which is located the axle OI a horizontal wheel which is free to rotate, attached to the l rim of and circumscribing this wheel is a blade of rubber, plastic, neoprene or other such resiliant material which protrudes above the rim of the said wheel; so that by adjustment of the afore-mentioned frame, the blade of the wheel can be brought into contact with the conveyor belting such that one side of the wheel has a greater contact pressure with the belt than the other side of the : wheel whereby the linear velocity of the belt will cause -the wheel to revolve and the blade will scour the belt . with a circular sweeping motion.
:. Where the structure of the conveyor installation is ~
~ 25 not rigid, the frame is preferably supported on extensible : legs located on the floor beneath the conveyor.
Where it is desirable to clean the upper surface of conveyor belt, the fra~e may be attached to the supports ¦ surrounding the conveyor and located between the upper and lower belts.
