Abstract

A high cleat rubber carrier system for conveying material at various angles, from generally horizontal to sixty degrees plus. The present invention also teaches a new and unique system for conveying chopped cane or bagasse at low, moderate, or high angles (for example, 40 degrees plus) during the refining process, for example, from a gravity chute to a donnely chute gravity compactor. Unlike traditional bagasse under-carrier conveyors, the present invention teaches a top carrier conveyer arrangement, which, as designed, has been found to convey even traditionally difficult materials, including, for example, chopped cane, bagasse, and other fibrous materials, even at relatively high angles, with little or no clogging. The present invention contemplates a skirted, cleated, endless belt conveyer having a transition plate disposed adjacent to the discharge chute, the transition plate affixed to catch return underpan situated below the conveyor, for catching debris or "carry back" missing the discharge chute, to re-feed the debris back onto the conveyor.

a frame having first and second ends, upon which there is laterally and rotatingly affixed thereto a tail and head pulley, respectively, said frame further having upper and lower sides and first and second edges;

an endless belt formed of a continuous member of flexible, sheet-type material, said belt having a conveying side, upon which emanates from the medial area of said belts conveying side a plurality of evenly spaced and generally laterally situated, projecting cleats having outer edges, said conveying side of said belt having a first and a second generally flat outer edge area disposed about said medial area of said belt, respectively, said belt running longitudinally along the upper side of said frame, about said first and second ends of said frame, and generally below said under side of said frame;

first and second skirts affixed to said upper side of said frame, said first and second skirts situated above said first and second outer edge areas of said belt, respectively, each of said first and second skirts having an inner side and an outer side, said inner side of each skin facing said cleats, each of said skirts having first and second ends;

a first belt edge seal having first and second edges, said first edge affixed to the outer side of said first skirt, said second edge in consistent, sliding communication with and providing bias against said first outer side area of said belt, thereby preventing material from migrating under said first skirt, while providing consistent pressure on said first outer side of said belt;

a second belt edge seal having first and second edge, said first edge affixed to said outer side of said second skirt, said second end of said second belt edge seal in consistent, sliding communication with, and providing bias against, said first outer side area of said belt, thereby preventing material from migrating under said second skirt, while providing consistent pressure on second outer side of said belt;

discharge means situated at said second end of said frame for discharging material from said belt;

an underpan having first and second ends generally corresponding with said first and second ends of said frame, said underpan generally being longitudinally aligned with and situated under said lower side of said frame, said underpan having a bottom wall and first and second, opposing, side walls, said underpan configured to engage said belt running generally below said underside of said frame, and envelope the outer edges of said cleats of said belt, said second end of said underpan adjacent to said discharge means, said second end of said underpan having further situated thereby, within said discharge means, a transition plate downwardly emanating at a 20-50 degree angle back toward the frame;

a boot having first and second ends, said first end affixed to said underpan, said second end affixed to said first ends of said first and second skirts, said boot enveloping said first end of said frame and said outer edges of said cleats and the portion of said belt in communication with said tail pulley.

2. The conveyor of claim 1, wherein each of said first and second side walls of said underpan has affixed thereto a support member configured to engage and support said outer side wall of said belt.

3. The conveyor of claim 1, wherein there is provided belt alignment means for maintaining said belt in alignment with said head and tail rollers.

4. The conveyor of claim 1, wherein there is provided a plurality of generally laterally situated, generally aligned, support rollers supported by said frame between said head and tail pulleys.

5. The conveyor of claim 4, wherein there is provided an impact pad juxtaposed between said support rollers.

6. The conveyor of claim 1, wherein there is provided magnetic means situated above said skirts for attracting ferris material from said conveyed material on said belt.

discharge means situated at said second end of said frame for discharging material from said belt;

an underpan having first and second ends generally corresponding with said first and second ends of said frame, said underpan generally being longitudinally aligned with and situated under said lower side of said frame, said underpan having a bottom wall and first and second, opposing, side walls, said underpan configured to engage said belt running generally below said underside of said frame, and envelope the outer edges of said cleats of said belt, said second end of said underpan adjacent to said discharge means;

a boot having first and second ends, said first end affixed to said underpan, said second end affixed to said first ends of said first and second skirts, said boot enveloping said first end of said frame and said outer edges of said cleats and the portion of said belt in communication with said tail pulley;

b. juxtaposing said conveyor at an incline between said first and second mills, such that said first end of said frame Is generally adjacent to said base of said first mill, and said second end of said frame is adjacent to said donnely chute on said second mill;

c. positioning said gravity chute of said first mill such that bagasse flows from said first mill to said top conveying area of said conveyor;

d. engaging said drive means for driving said belt;

e. utilizing said cleats on said belt to urge bagasse up said incline, conveying said bagasse up said frame;

f. dispensing said bagasse into said donnely chute;

g. capturing any remaining bagasse situated on said belt after having passed said head pulley; and

h. utilizing said cleats on said belt to guide any remaining bagasse on said belt through said underpan, through said boot, and back onto said top conveying area of said conveyor.

7. A conveyor for conveying a material away from a first material handling area, at an angle and discharging said material via gravity to a second material handling area, said conveyor comprising:

frame having first and second ends, upon which there is laterally and rotatingly affixed thereto a tail and head pulley, respectively, said frame having situated thereon between said head and tail pulleys a plurality of generally laterally Situated, somewhat aligned, support rollers, said support rollers having juxtaposed therebetween an impact pad, said frame further having upper and lower sides and first and second edges;

an endless belt formed of a continuous member of flexible, sheet-type material, said belt having a conveying side, upon which emanates from the medial area of said belts conveying side a plurality of evenly spaced and generally laterally situated projecting cleats having outer edges, said conveying side of said belt having a first and a second generally flat outer edge area disposed about said medial area of said belt, respectively, said belt running longitudinally along the upper side of said frame, about said first and second ends of said frame, and generally below said under side of said frame;

first and second skirts affixed to said upper side of said frame, said first and second skirts situated above said first and second outer edge areas of said belt, respectively, each of said first and second skirts having an inner side and an outer side, said inner side of each skirt facing said cleats, each of said skirts having first and second ends;
