Planting machine for potatoes, bulbs or similar seed crop

A planting machine for potatoes, bulbs or similar seed crop comprising a hopper and a conveying and distributing device adjoining an outlet port of said hopper for feeding the potatoes or the like to the planting foot, characterised in that the conveying and distributing device is formed by a conveyor belt extending beneath the outlet port of the hopper and having above the conveyor belt two discs rotating in opposite senses and being located side by side adjacent one another, said discs having the shape of an obtuse cone with an adjoining, annular, flat outer rim located just above the conveying surface of the belt, the adjacent parts of the discs moving in the same direction as the conveyor belt, said discs being surrounded on the side remote from the hopper through a circumferential angle of about 180.degree. with a slight interspace by an upright rim, and at the opposite sides of the conveyor belt conveying members are arranged to be movable in opposite direction to that of the conveyor belt, said conveying members having pick-up ends lying beneath the outer rims of the respective discs and delivery ends lying above the planting foot, there being provided pick-up members on said conveying members causing the potatoes or the like lying on the flat rim portion of each disc to slide off the disc onto the conveying members wherein the linear circumferential speed of the discs exceeds the linear speed of the conveying members.
