The invention relates to a potato planting machine with one arranged horizontally one above the other Axles revolving cup chain for scooping the potatoes from a storage container and with one arranged over a fixed plate base, divided into compartments and around one vertical axis rotating cellular wheel, which is driven intermittently in the event of scooping errors and the reserve potatoes in the compartments through an opening in the bottom of the plate deposits the cup chain near its upper turning point.

In the known potato machines of this type, the cellular wheel for the cup chain is arranged in such a way that its axis of rotation is in the conveying plane in front of or behind the cup chain. Accordingly the opening of the plate bottom is at the front or at the back. The reserve potatoes in the compartments fall on the chain of cups when the subjects in question are roughly in their foremost or rearmost position. This arrangement is only satisfactory at low laying speeds which the reserve potatoes are slowly pushed over the edge of the plate bottom opening and then fall almost perpendicular to the chain of cups.

This known arrangement leads to great difficulties for higher laying speeds. That Correspondingly faster rotating cell wheel divides the reserve potatoes in the compartments large kinetic energy with, so that this when passing the plate opening a trajectory parabola transversely to the Describe the plane of movement of the cup chain. They hit the side wall of the laying pipe and are deflected in an uncontrollable manner, so that they moved across the trajectory The chain of cups does not arrive at the right time and does not fall onto the empty scoop. Rather, because of the unintentional acceleration processes either too early or too late can get onto the cup chain, there is a risk that the scooping errors are not only not compensated for but that by adding reserve potatoes to one of the already filled ones Scoop, the evenness of the row of plants is further deteriorated by double assignments will with all the resulting plant cultivation consequences.

The present invention avoids these disadvantages in that the axis of rotation of the cellular wheel arranged next to the plane of movement of the bucket chain and the distance equal to the conveying radius of the bucket wheel is. This throws the fast moving

Cell wheel removes the reserve potatoes at the point where the conveyor arc of the gear wheel sets the plane of movement the chain of cups touches so that the trajectory is in the plane of movement of the chain of cups lies. The potatoes do not experience any change of direction, but they get there without hitting the

ao correct scoop, so that the imperfections are compensated fulfills its task even at higher laying speeds.

One embodiment is shown in the patent sketch in perspective.

The scoop 3 of the chain 1 migrate ascending through the potato storage container 2, wherein they fill up with potatoes. The bucket chain is diverted via a sprocket 4 and migrates then in the laying tube 5 downwards. At the lower end of the laying tube, the potatoes are placed in the furrow thrown off. Above the chain of cups is in connection with the potato storage container 2 and the Laying tube 5 of the plate bottom 6 attached so that the opening 7 in it is approximately above the Sprocket 4 is located. The cellular wheel 8, which is used to hold reserve potatoes, is mounted in the bottom of the plate is divided by the compartment walls 10 into individual compartments. The axis of rotation 9 of the bucket wheel is arranged next to the plane of movement of the bucket chain 1, the distance of the axis of rotation from the The plane of movement of the bucket chain corresponds to the conveying radius of the star feeder. The axis of rotation 9 is located to the side of the sprocket 4.

If individual scoops 3 have not filled up in the storage container 2, the imperfections are compensated for by rotating the cellular wheel 8 intermittently by one compartment division and depositing the potatoes through the opening 7 on the chain of cups. The direction in which the reserve potatoes are dropped is indicated by the arrow α and the direction of movement of the chain of cups is indicated by the arrow b. Because both movements go in the same direction

fen, deflections of the potatoes are avoided, and they arrive immediately if there is a defect on the empty scoop.
