MOBILE VIBRATING SCREEN WITH FLEXIBLE SHAFT
First Claim
Patent Images
1. A mobile system for screening material comprising:
- an elongated structure configured to be rolled over the surface of a public roadway;
a vibrating screen assembly coupled to and supported by said elongated structure;
a means for receiving rotary power and causing said vibration screen assembly to vibrate;
a source of rotary power disposed outside of said vibrating screen assembly and configured so as to be pivoted between operational and transport modes, where the transport mode provides a reduction in a maximum dimension of a combination of said vibrating screen assembly and said source of rotary power;
said source of rotary power being free from a closed loop elongated flexible member which couples and provides power transmission from a first circular member and a second circular member which are configured to receive said closed loop elongated flexible member, such that a separation distance between centers of said first circular member and said second circular member vary during one of operation of the vibrating screen and conversion from said operational mode and said transport mode.

Abstract
A mobile vibrating screen with a readily stowable and pivoting drive system comprising a motor with an attached drive sheave, a belt, a driven sheave and plurality of universal joints which are configured to maintain a connection between the motor and an eccentric weight shaft when said drive system is switched from an operational configuration to a stowed configuration. In an alternate embodiment, some small d parts, e.g. drive shaft, need to be removed and stowed elsewhere on the plant when drive is converted from operation to transport.

9. A mobile vibrating screen comprising:
-
a base for providing structural support; said base being mobile and supported by wheels and further structured and configured for travelling on a public roadway; a motor for providing rotational energy coupled pivotally with the base; a screen coupled to said base and configured to discriminate material when vibrated; an eccentric weighted shaft which is positionally fixedly coupled to said base while allowing rotation of the eccentric weighted shaft so that rotation causes the screen to vibrate; a flexible drive shaft disposed between and rotationally coupling said motor with said eccentric weighted shaft which comprises; a first universal joint, a second universal joint and a telescopic shaft disposed between said first universal joint and said second universal joint. - View Dependent Claims (10, 11, 12, 13)

14. A mobile vibrating screen material discriminator comprising:
-
a frame; a screen, coupled to said frame, said screen having a predetermined opening size characteristic for discriminating a predetermined size of material from other larger material; means for transferring energy of rotation into vibration of the screen; a motor for generating rotational energy; means for deploying a drive system from an operational configuration to a transport configuration, such that when said drive system is converted from said operational configuration where rotation energy is transferred from the motor to said means for transferring;
to the transport configuration, there is no need to disconnect said drive system from one of said motor and said means for transferring. - View Dependent Claims (15, 16, 17, 18, 19, 20)
