## Abstract

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM”, is a conveyor for grains, seeds, fruit, granulated and ground products and similar products. The conveyor has different applications and isolates the product conveyed from the drive system. There are two or more tubes, and in each set of tubes there is a swivel with a drive system using roller chain, chain, cable, belt, et cetera. In this manner, the drive system is isolated from the product, avoiding mechanical damages, contamination, and also increasing the performance of the system.

## Claims

### Claim 1

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM” is a conveyor (1) of grains, seeds, fruit, granulated and ground products and similar products, with two or more conduits (2) in closed circuit. The conduits (2) receive the product from the hoppers (A) and distribute to the storage silos (B), being the conveyor (1), characterized by having an transmission and drive system (3), between two conduits (2), however, the transmission and drive system (3) is on the outside part and does not make contact with the products transported; the conveyor (1) has two or more conduits (2) in closed circuit, united and welded parallel on their entire extension by two U shaped beams (4) across front each other, and in their central wall (4A), there are two rulers or a nylon frame (5), used to avoid friction and noise of the transmission chains (6). The chains (6) are located symmetrically centered between the frames (5) and the conduits (2). The chain (6) has in its laterals many nylon sealing plates (7), and fixed in the extremities of its links, many drag sets (8), which slide freely in the interior of the conduits (2). Each drag set (8) has a triangular base (8A) which supports the oblong reinforcement (8B) of the drag circular insert (8C).)

### Claim 2 (depends on 1)

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM” according to claim 1 is characterized by having conduits (2) divided in blocks which are united by an oblong connection flange (9) located at the extremities of the conduits.)

### Claim 3 (depends on 1)

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM” according to claim 1 is characterized by each angle (10) of the conveyor (1) has a sprocket (11), which spins around a shaft (12) and a thrust bearing (13). These three pieces are positioned between two plates of triangular support (14) and the sprocket (11) is used for traction of the links of the chain (6).)

### Claim 4 (depends on 1)

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM” according to claim 1 is characterized by the traction system (14) has a gearbox (14A), which starts the sprocket (11), located in one of the angles (10).)

### Claim 5 (depends on 1)

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM” according to claim 1 is characterized by the conveyor (1) has an automatic tensioning system (15), with a set of three sprockets (15A). Each sprocket has a sliding central piece (15B), interconnected by a cable (15C), to a sheave (15D) and a counterweight (15E).)

### Claim 6 (depends on 1)

“CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM” according to claim 1 is characterized by the transmission system is by chain (6); roller chain; cables or belts.
