The invention relates to potato machines in which a rotatable above the laying pipe inlet Storage plate is arranged, under which there is a fixed floor with a potato passage opening is located. The storage plate is through vertical radial walls for receiving individual potatoes in compartments divided, and there is one with one of the radial walls rigidly connected to a radial axis of rotation in each compartment pivotable bottom flap arranged with its end opposite the axis of rotation is supported on the fixed floor and swings around when crossing the potato passage opening and sags freely downwards.

There are potato planting machines of this type are known, in the storage plate of which the radial walls are rigidly attached are and whose bottom flaps are hinged to the rigid radial walls. With machines like this leaves the supply plate only rotate in one direction, because the open flap rotates when moving in the opposite direction Place the direction of rotation against the associated radial wall and block further rotation. With machines This type of bending of the bottom flaps or damage occurs when the planter is pushed back of the drive, unless the drive of the supply holder with an automatic when recoil disengageable clutch is provided. Such couplings make the spreading machine more expensive.

Furthermore, planters are known in which the potatoes in the cutouts of a rotating Disc are inserted, on the underside of which bottom flaps are hinged. Instead of a fixed one At the bottom, a guide track with a ramp is arranged below the disc, which the incoming Gradually swings up the bottom flaps. There is an approach ramp on the opposite side of the guideway not available, so that the bottom flaps suddenly fall down when this end of the track is reached, as is necessary for an even potato discharge. So the rotating disk is can only be used in the direction of the run-up ramp; if rotated in the opposite direction, the Bottom flaps hit the straight end of the web and get damaged.

Furthermore, as already mentioned, spreading machines are known in which the radial walls around Rotary axes arranged radially in the supply plate are pivotable and each have a rigid radial wall a bottom flap is connected, so that the radial wall and the bottom flap are only pivoted together can be. In the known machines of this type, the axes of rotation are on the underside of the supply plate arranged. This can only be done in a potato planter

Rotate the direction of rotation, because in the opposite direction of rotation, the one hanging over the laying pipe inlet Support the bottom flap with the part serving as a radial wall against the fixed floor and would block the further backward movement of the supply plate. These machines also need therefore to protect against breaks that would occur when the laying machine recoils, one special clutch.

The invention has the advantage that the supply plate moves unhindered in both directions of rotation can be without the plate drive requiring a reverse locking mechanism or a clutch.

The invention consists in that the radial axes of rotation of the bottom flaps from the plate bottom one way have a large distance that the radial walls in one by reversing the direction of rotation of the supply plate caused pivoting do not come into contact with the bottom of the plate. Preferably each closes Radial wall with the base flap rigidly connected to it in a manner known per se acute angle that is open at the bottom in the loading position.

An embodiment is in

F i g. 1 shown in perspective;

F i g. 2 shows as a detail the pivotable unit consisting of bottom flap and radial wall in a side view, namely in the potato receiving position, the free end of the flap resting on the fixed floor.

The supply plate 1 consists of the disc hub 2 and the outer ring 3, which are arranged like spokes Radial bolts 4 are rigidly connected to one another. The radial bolts subdivide the storage plate into several compartments, each designed to hold one potato. The supply plate will

by means of a drive, of which only the drive pulley 5 is shown in the drawing, from the ground set in rotation. Below the supply plate is the one on, not shown here Machine frame rigidly attached, fixed floor 7. This points above the laying pipe inlet 8 a potato passage opening 9. On each radial bolt 4 acting as an axis of rotation an angularly bent piece of sheet metal pivotably mounted, the longer leg of which as a flap 10 and whose shorter leg is designed as a radial wall 11.

The bottom flaps 10 are supported with their free end on the fixed bottom 7, whereby they assume an inclined position in a manner known per se. If you put a potato in one of the compartments, so it therefore rolls on the inclined bottom flap to the next radial wall. When the bottom flap reaches the potato passage opening 9, it pivots in a vertical position and gives the potato the way into laying pipe 8 free. If you turn the supply plate further, the sagging bottom flap will sag Approaching the edge of the potato passage opening 9 raised again into its inclined position. If the supply plate is rotated backwards, as is the case with turning and pushing back the machine regularly happens, the sagging bottom flap runs along with the attached radial wall on the opposite one Edge of the potato passage opening and is taken as a result of the invention Arrangement of the axis of rotation 4 tilted up, so that the reverse rotation of the supply plate is unhindered he follows.

Claims (2)

Patent claims: 1. Potato planting machine with a potato passage opening above the laying pipe inlet having a fixed floor, above which a compartment divided into compartments by vertical radial walls Storage plate is rotatably arranged, in which in each compartment one with one of the radial walls rigidly connected bottom flap pivotable about a radial axis of rotation is arranged, which is supported with its end opposite the axis of rotation on the fixed floor and swivel around when crossing the potato passage opening and then freely downwards can sag, characterized in that the axis of rotation (4) from the plate base (7) has such a large distance that the radial walls (11) when reversed by the direction of rotation of the supply plate (1) caused pivoting not in contact with the plate base (7) come. 2. Potato planting machine according to claim 1, characterized in that each radial wall (11) with the base flap (10) rigidly connected to it, in a manner known per se, a pointed, in Load position includes downward open angle.
