4 Claims.
This invention relates to an improved device .for removing foreign material from belts.
1 ore and other materials and particles of these materials tend to adhere to the belt after pass- Such accumulations of foreign materials interfere with the proper operation and function of the belt and the problem of preventing accumulations is especially acute for belts exposed to outside weather conditions although the problem is not confined to such locations.
Various types of belt cleaning devices have been suggested. Power-driven, rotary brushes have been proposed but they are readily clogged I by ice and snow and are relatively expensive to install and maintain. Both stationary and resiliently supported scraper blades mounted on leaf springs or counter-balanced arms have been proposed. The stationary blades cause excessive wearing away of the elements, while the resiliently supported blades tend to chatter which results in non-uniform removal of the accumulated foreign material. Consequently, the cleaning devices of the prior art have not been entirely satisfactory.
A primary object of this invention is to pro-' vide an improved belt cleaning device for removing ice, moisture, slime, and other foreign materials that does not become clogged even when used under extremely adverse conditions.
A further object of. this invention is to provide a belt cleaning device which will not chatter and which will uniformly remove all of the foreign material adhering to the belt.
It is also an object of this invention to provide an improved belt cleaning device which is economical to install and maintain, which is 'efficient in operation, and which is suiiiciently sturdy to have a relatively long operating life.
The present invention provides an improved belt cleaning device which includes at least one and preferably a plurality of metal scraper blades.- The blades are supported in a novel manner so that they do not chatter, do not become ineffective from fouling of the blades with accumulated foreign material and do not damage the belt or cause excessive wearing away of the elements.
This is achieved by providing resilient means separately urging the opposite end portions of the cleaning blades toward and into contact with the surface of the belt being 23 on each corner post.
'2 cleaned whereby the blade end portions have substantially independent floating movement toward and away from the belt surface.
These and other objects and advantages will become more apparent when considering the following description along with the accompanying drawings, in which:
Figure 1 is an isometric view of a belt cleaning apparatus embodying the principles of the present invention;
Figure 2 is a side elevational view of the apparatus of Figure 1 in position for cleaning a belt; and
Figure 3 is an enlarged fragmentary view taken along the line 3-3 of Figure 1 and showing the details of the support at one end of one of the belt cleaning blades.
The belt cleaning device In is mounted on a suitable support ll adjacent a belt l2 having ing device 10 may be a separate support or may .be part of the belt supporting apparatus.
The belt cleaning device In includes a first pair of corner posts 16 and I I and a second. pair of corner posts I 8 and I9. Each corner post is similarly supported at its lower end on support I! and with its upper end extending through .a bracket 20 .rigidly supported in any suitable manner. Each corner post is preferably slidable through member 2-0 so as to facilitate dismantling of the cleaning device. There is an adjustable, normally fixed collar 22 with a set screw A second collar 24 is slidably mounted on each post. A spring 25 encircles each post between each pair of collars 2 1 and 22, and urges the corresponding collar 2-4 upwardly toward surface l3 of belt [2.
support 21 includes a pair of cross-members 29 and 30 extending transversely of the belt surface 13. The cross-member 29 supports theend portions 3| of blades 26 and is connec ed at each of its ends through a rod 33 to the slidable collar 24 mounted on the corresponding one of the first pair of corner posts 16 and [1. The other crossmember 30 supports the opposite end portions 32 of blades 26 and is similarly connected through corresponding 'rods 33 to the s'lida'ble collars 24 on the pair of corner posts I8 and 19. The end of each cross-member and the corresponding rod 33 and collar 24 are so constructed and arranged that each cross-member may tilt relative to the collar 24 and so that frame 21 may tilt and properly position itself and blades 26 in responseato variationsuin theslopof belt l2. End member 34 extend between and are connected to the end portions of the crossmembers 29 and 30. The end members 34 may be omitted.
With this construction, the springs.2.5,on.posts. I6 and I! resiliently urge cross-member 29 and the end portions 3| of blades 2firtoward and into contact with the surface -l3'of'belt. l2" and-the= other springs on posts [8 and I9 resiliently urge the cross-member 3!! and the endiportionsw 32 of blades 26 toward the surface l3. Thus, the
opposite end portions 3| and 32 of theblades 26-- are separately, resiliently urged toward the surface 1 3? and the. blade. end. portions shave independentfioating movement in direction toward and away fromzthe-surface is which decreases harmful abrasion; eliminates chatter and results in' more: uniformvcleaning, all 'aswill be more fully pointed'out when describing the operation of the cleaning device.
The blades 2E may' be formed' of any suitable material but are-preferably: formed of metal,
Metal blades are more nearly self cleaning and Prior to or during operation of the belt clean- I ing device Ill, the set screws. 23 may be loosened and the collars 22 individually vertically adjusted so. that. each spring 25 pushes upwardly the .proper amount and the collars then locked in -position by tightening the.screws 23. Normally the blades 26 will. be urged against the belt surface I3Jbutl in some locations it .may be desirable to have the. upper. edgesof the blades normallyspacedfrom the belt surface l3 a slight amount. Byspacing the, blade. edgesv from the.
belt friction. and abrasionare reduced-to a minimum while ..accumulations...of appreciable quantity, are removed.
Whenthe pulley rotates ina clockwise direction andthe. return side of belt I 2 .moves .towardsthe.
left asindicatedin Figure.,2,.the.belt does not move in astraight lineor in. afixed plane, but will undulate. With thepresent device the .blade supporting frame 21-.and the blades can readily tilt to .follow. both. the. longitudinal .and: transversegundulations. of. the belt -soas to maintain a maximumlamount ofeach blade incontact with the.belt.. An. abruptwave in. the belt or-alprotuberanceonthe belt surface w-ill often bemoving at sufficient speed: so thatthe impact against the blade will. tendtodrivethe bladeaway from the. belt :with sufilcient. momentumsothat there is zagtendency for the blade 3 to move acompletely away, --from.- the-belt surface. Withthe present device, if aprotubera-nce strikes an-end port on ofblade, the opposite end portion is not moved away from the belt as the opposite end portions of the blades have separate floating movement. Thus, the present invention also eliminates or greatly reduces all tendency of the blades to chatter. When blades chatter, they do not uniformly remove theiaccumulationsand cleanthe belt.
