Abstract

Disclosed is an inclined mobile screen for processing road building materials which provides for easy reconfiguration of the screen from operation configuration to a transport configuration and to a maintenance configuration, which allows for increased clearance between the screen and a feed conveyor without requiring a hydraulic actuator disposed therebetween. Nested telescopic supports are selectively coupled together in an offset connection to allow changes in the orientation of the screen to result in changes in the separation between the screen and the conveyor so as to allow for more clearance therebetween during time of maintenance.

First claim

We claim:

1 . A material sorting screen comprising:
a vibrating screen coupled to a screen base, which screen base is pivotally coupled at one end to a base mainframe; an overhead feed conveyor configured to provide material to be screened to the vibrating screen at various operating angles; said overhead feed conveyor is coupled to the screen base via the screen base to a first conveyor support which comprises a first portion and a second portion; and a screen maintenance link which is selectively coupled, through an offset connection, between the first portion and the second portion, so that when said screen maintenance link is coupled to the first portion, and the vibrating screen is lowered, a combined length of the screen base to the support is more than it would be if the vibrating screen were lowered to a horizontal position without coupling the screen maintenance link.

2 . The material sorting screen of claim 1 further comprising: a source of hydraulic power disposed between and configured to cause relative motion between said screen base and said base mainframe.

3 . The material sorting screen of claim 2 wherein said vibrating screen is free of any hydraulic and electric components which provide power to cause relative motion between said screen base and said overhead feed conveyor, other than said source of hydraulic power disposed between and configured to cause relative motion between said screen base and said base mainframe.

4 . The material sorting screen of claim 3 further comprising: a removable maintenance link pin used for coupling said screen maintenance link to said first portion.

5 . The material sorting screen of claim 4 wherein an output end of said overhead feed conveyor is detachably coupled to said screen base.

6 . The material sorting screen of claim 4 wherein said overhead feed conveyor is detachable through translation of a protuberance along an open-ended slot.

7 . The material sorting screen of claim 3 wherein said base mainframe to conveyor support is rigidly coupled to said base mainframe.

8 . The material sorting screen of claim 5 wherein said overhead feed conveyor is detachable through translation of a protuberance along an open-ended slot.

9 . The material sorting screen of claim 8 wherein said vibrating screen is fixed to said screen base.

10 . The material sorting screen of claim 1 wherein said first portion and said second portion are each portions of a tube in tube support leg.

11 . A material sorting screen comprising:
a screen coupled to a base, which base is coupled at one end to a base mainframe; an overhead feed conveyor configured to provide material to be screened to the screen at a plurality of operating angles; said overhead feed conveyor is coupled to the base via a base to a multi-piece support system; and a maintenance link which is coupled, through a connection, between a first piece of said multi-piece support system and a second piece of said multi-piece support system, so that when said maintenance link is coupled to the first piece, and the screen is lowered, a combined length of the base to the multi-piece support system is more than it would be if the screen were lowered to a horizontal position without coupling the maintenance link.

12 . The material sorting screen of claim 11 wherein said multi-piece support system comprises a tube in tube support leg.

13 . The material sorting screen of claim 11 wherein said multi-piece support system comprises at least two rigid members capable of limited relative movement therebetween.

14 . The material sorting screen of claim 13 further comprising: a removable maintenance link pin used for coupling said maintenance link to a first rigid member of said at least two rigid members.

15 . The material sorting screen of claim 13 wherein said limited relative movement therebetween is parallel movement.

16 . The material sorting screen of claim 15 wherein said parallel movement is co-axial movement.

17 . The material sorting screen of claim 13 wherein said base mainframe to conveyor support is rigidly coupled to said base mainframe.

18 . The material sorting screen of claim 15 wherein said overhead feed conveyor is detachable through translation of a protuberance along an open-ended slot.

19 . The material sorting screen of claim 18 wherein said screen is fixed to said screen base.

20 . The material sorting screen of claim 19 further comprising a conveyor tube in tube support leg which comprises an outer tube and an inner tube.
