Abstract

A mobile collapsible screen and cone crusher combination where the screen is pivoted forward and downward for transport and a rubber hopper is coupled to the fines conveyor so as to permit a hinged connection and a sliding connection between the flexible hopper and the fines conveyor. A plurality of flexible matter edge plates are used at the rear of the flexible hopper to facilitate proper compression and expansion of the flexible hopper. A selectable maintenance catch is used to allow the screen to be elevated to an intermediate height for maintenance.

Claims (37)

1. A mobile material processing plant comprising:

a mobile frame support;

a vibrating screen plant for separating material;

a pivoting screen support leg, coupled to said mobile frame support and said vibrating screen plant, so that said vibrating screen plant can be simultaneously lowered and moved forward with respect to said mobile frame support;

a fines conveyor coupled to said mobile frame support, for transporting material;

a flexible hopper disposed between said vibrating screen plant and said fines conveyor; and

said flexible hopper detachably coupled to said fines conveyor, such that a bottom edge of said flexible hopper is guided downward and inward toward a center line of said fines conveyor by a hinge connection which is configured free to translate forward along a longitudinal axis of said fines conveyor and pivot about an edge of said fines conveyor; when said vibrating screen plant is lowered and moved forward for transportation.

2. The system of claim 1 further comprising:

a sliding and pivoting brace member configured to move along said mobile frame support top rail during transition between a collapsed transport configuration and elevated operational configuration.

3. The system of claim 2 further comprising:

a automatic deployed position brace pivoting catch, configured to automatically capture one of said plurality of sliding and pivoting brace members, when the vibrating screen plant is raised upward to an operational configuration.

4. The system of claim 3 further comprising:

a brace terminal rail contacting pin disposed on one of said plurality of sliding and pivoting brace members.

5. The system of claim 4 wherein said flexible hopper comprises at least 3 sides.

6. The system of claim 5 further comprising a stationary rear hopper chute which remains stationary with respect to said mobile frame support when one of said plurality of sliding and pivoting brace members is pivoted to transform said system from an operational mode to a transport or maintenance mode.

7. The system of claim 5 further comprising a flexible rear hopper portion comprising a flexible rear hopper panel with a plurality of rigid guide members coupled to said flexible rear hopper panel so that when one of plurality of sliding and pivoting brace members is pivoted said flexible rear hopper panel is permitted to flex in only one direction so that an exterior of said flexible rear hopper panel is in a convex orientation and extending in a direction opposite of a direction of motion of said flexible hopper along the longitudinal axis of said fines conveyor.

8. The system of claim 7 further comprising a hinge pivoting range limiter disposed on a side of said fines conveyor.

9. The system of claim 8 further comprising:

a plurality of pivoting screen support legs, which includes said pivoting support leg, coupled to said mobile frame support and said vibrating screen plant, so that said vibrating screen plant can be simultaneously lowered and moved forward with respect to said mobile frame support.

10. A mobile material processing plant comprising:

a mobile frame support;

a vibrating screen plant for separating material;

a pivoting screen support leg, coupled to said mobile frame support and said vibrating screen plant, so that said vibrating screen plant can be simultaneously lowered and moved forward with respect to said mobile frame support;

a fines conveyor coupled to said mobile frame support, for transporting material;

a flexible hopper, having at least three sides, disposed between said vibrating screen plant and said fines conveyor;

said mobile frame support having a mobile frame support top rail;

a stationary hopper rear portion coupled to and stationary with respect to said mobile frame support;

a sliding and pivoting brace member configured to move along said mobile frame support top rail during transition between a collapsed transport configuration and elevated operational configuration;

a automatic deployed position brace pivoting catch, configured to automatically capture one of said plurality of sliding and pivoting brace members, when the vibrating screen plant is raised upward to an operational configuration;

a brace terminal rail contacting pin disposed on one of said plurality of sliding and pivoting brace members;

wherein said means for funneling comprises a hopper with rubber panel portions.

11. The system of claim 10 wherein said powered means is a fines conveyor.

12. The system of claim 10 wherein said vibrating means comprises vibrating screen plant.

13. The system of claim 1 wherein said flexible hopper comprises at least 3 sides.

14. The system of claim 1 further comprising a hinge pivoting range limiter disposed on a side of said fines conveyor.

15. The system of claim 1 further comprising:

a plurality of pivoting screen support legs, which includes said pivoting support leg, coupled to said mobile frame support and said vibrating screen plant, so that said vibrating screen plant can be simultaneously lowered and moved forward with respect to said mobile frame support.
