ABSTRACT:
An improved portable seeder particularly adapted for agricultural cultivation of seedlings is characterized in its turning plate driven by a transmission mechanism having a two-section structure including a concentrically disposed inner and outer section; and a base mount disposed under the turning plate is provided with a number of through holes in correspondence to the outer section of the turning plate so as to prevent the turning plate from getting stuck in operation by the seeds. The present seeder employs a dispelling stick which is actuated to move to and fro by the transmission mechanism; and the base mount provided with a plurality of through holes thereon is disposed under the turning plate so as to permit seeds falling under the turning plate to be expelled without getting the same stuck in operation. A feeder plate and a control plate each having a pair of feeding holes that are disposed in non-alignment with each other so that the rotatation of the control plate can vary the size of the spreading opening and a rudder member is also provided whereby the operation thereof becomes easy and secure with less chance of getting stuck, and the seeding process is carried out in a more smooth and even manner.
