Vent Assembly For A Grain Bin

Abstract

A roof vent assembly wherein the grain bin has a corrugated cylindrical wall and a roof structure having a plurality of triangular roof panels. A vent assembly is connected to the roof. The vent assembly has a base. The base has a back wall, two side walls and a front wall which extend upwardly from the flange. The back wall and sidewalls are generally straight whereas the front wall extends outwardly to a point, peak or crest. When connected to the grain bin roof, the peak of the vent assembly is positioned to point upwardly. This peak prevents the build up of moisture and debris thereby extending the life of the grain bin roof assembly.

1 . A roof vent assembly comprising:
 a base portion and hood portion having a front wall and sidewalls;   a removeable back wall;   wherein the front wall has a pair of panels that extend from a top edge to a bottom.   
     
     
         2 . The roof assembly of  claim 1  wherein the sidewalls and front wall taper inwardly as they extend from the base portion to the hood portion. 
     
     
         3 . The roof assembly of  claim 1  wherein a canopy extends outwardly from the hood portion. 
     
     
         4 . The roof assembly of  claim 3  wherein the canopy has openings. 
     
     
         5 . The roof vent assembly of  claim 1  wherein the panels form a partial pyramid. 
     
     
         6 . The roof vent assembly of  claim 1  wherein the panels form a partial sphere. 
     
     
         7 . A roof vent assembly comprising:
 a base having a bottom edge and a top edge;   said base having a front wall, a pair of sidewalls and a back wall;   said front wall extending outwardly in relation to the sidewalls.   
     
     
         8 . The roof vent assembly of  claim 7  wherein the front wall has an elongated portion that tapers from the bottom edge to the top edge. 
     
     
         9 . The roof vent assembly of  claim 7  wherein the sidewalls taper inwardly towards one another from the bottom edge to the top edge. 
     
     
         10 . The roof vent assembly of  claim 7  wherein the back wall tapers inwardly towards the front wall as it extends upwardly from the bottom edge to the top edge. 
     
     
         11 . The roof vent assembly of  claim 7  wherein a hood assembly is connected to the base. 
     
     
         12 . The roof vent assembly of  claim 7  wherein a plurality of bases nest within one another in a vertical alignment. 
     
     
         13 . The roof vent assembly of  claim 7  wherein a canopy extends outwardly from a hood member and covers the peak. 
     
     
         14 . The roof vent assembly of  claim 13  wherein the canopy has openings. 
     
     
         15 . A roof vent assembly comprising:
 a front wall, a pair of sidewalls and a back wall which extend upwardly from a bottom edge;   the front wall extends outwardly in relation to the sidewalls to form a peak; and   a seam separating the roof vent assembly into a pair of clamshells.   
     
     
         16 . The roof vent assembly of  claim 15  further comprising a canopy that extends outwardly over the peak. 
     
     
         17 . The roof vent assembly of  claim 16  wherein the canopy has openings. 
     
     
         18 . The roof vent assembly of  claim 15  wherein each side of the seam has a connection member for receiving the opposing clamshell.
