A hopper of a seeder is provided to obtain a constitution for preventing the overload and errors in seeding generated when a hopper shaft motor is stopped due to seeds that are not dropped. In a hopper of a seeder, one side of a gear shape rubber plate(14) is fixed with a bolt(15). A protrusion(16) is formed below the fixing portion of the bolt to make the rubber plate adhered to a hopper shaft(3) at a predetermined angle. The other side of the rubber plate is installed by using a spring(17) to make the rubber plate adhered to and elastically supported by the hopper shaft. A rubber plate is attached to the upper part of the hopper. A pig hair brush is attached to the hopper to make a seed drum(11) rotate without great resistance. |
