Dual seed meter for planting crops and improving crop yields

Abstract

Seed meter for planting different seed varieties including back cover, disk and front cover. Back cover includes seed separation device providing first seed pool area and second seed pool area with help of the back cover. First seed pool area receives first type seeds, and second seed pool area receives second type seeds from first seed chamber and second seed chamber, respectively of a seed hopper. Disk includes at least two rows of apertures disposed in alignment with first seed pool area and second seed pool area. Disk rotates with vacuum pressure and entrains the first type seeds and the second type seeds over the apertures until apertures rotate past an area where vacuum pressure is cut off from the apertures. First type seeds and second type seeds free-fall from the disk through a discharge chute in the back cover into a seed tube for depositing into a seed furrow.

         8 . A seed meter for planting different seed varieties, said seed meter comprising:
 a back cover comprising a first seed inlet chute and a seed discharge chute;   a front cover;   a seed separation device comprising a wall, said wall extending perpendicularly from said seed separation device and at a distance from the edge of said seed separation device, and wherein said seed separation device comprises a second seed inlet chute; and   a disk comprising two rows of first apertures and one row of second apertures,   wherein said back cover connects to said front cover, wherein said seed separation device connects to said back cover such that said second seed inlet chute inserts into said first seed inlet chute for creating a first seed pool area between said wall and said back cover and a second seed pool area at inner side of said wall via said second seed inlet chute,   wherein said back cover connects to a seed hopper, wherein said seed hopper stores and dispenses first type of seeds into said first seed pool area and second type of seeds into said seed pool area,   wherein said disk aligns with said seed separation device such that said first apertures align with said first seed pool area and said second apertures align with said second seed pool area,   wherein said disk rotates under vacuum pressure and entrains said first type of seeds through said first apertures from said first seed pool area and said second type of seeds through said second apertures from said second seed pool area until said first apertures and said second apertures rotate past an area where the vacuum pressure cuts off, and   wherein said first type of seeds and said second type of seeds free fall from said disk through said seed discharge chute.   
     
     
         9 . The seed meter of  claim 8 , wherein said wall comprises holes to distribute the vacuum pressure created in said seed separation device. 
     
     
         10 . The seed meter of  claim 8 , wherein said seed hopper comprises a first seed chamber storing the first type of seeds and a second seed chamber storing the second type of seeds. 
     
     
         11 . The seed meter of  claim 10 , wherein said seed hopper comprises a separation plate separating said first seed chamber and said second seed chamber. 
     
     
         12 . The seed meter of  claim 8 , wherein each of said first apertures and said second apertures comprises a concave cell for receiving respective first type of seed and second type of seed.
