The invention relates to a mobile device for dropping onions, tubers, seeds and other things more or less coarse-grained material on prepared seed soils, with a frame, a container for the material and at least one metering channel that is parallel to the direction of travel and that runs in the longitudinal direction is reciprocating by a shaker drive and adjustable with respect to the inclination.

The container of a known device of the type mentioned is on the frame in a proportion large distance from the seedbed above several metering channels, each in the area of the Inlet end are pivotably mounted on the frame and with the outlet end in a funnel-shaped Extension open at the upper end of an associated outlet pipe. This proceeds with proportionately great length steeply down to the seed bottom, so that the material falls at great speed on the The ground hits the ground and is scattered uncontrollably in several directions even if, how also known that the outlet pipe is fixedly arranged behind a furrow pulling device. This is on the one hand it is impossible to deposit the material in a straight line on the seedbed, while on the other hand there is a risk that especially with pre-germinated Well the germs or sprouts are damaged by the hard impact on the ground.

With the same disadvantages are all those of known spreaders or seed drills still affected, whose dosing channel systems are arranged at a relatively large distance above the floor, It does not matter whether the dosing channel system runs parallel or transversely to the direction of travel and in each case either through pairs of claws rotating in opposite directions or several metering channels arranged next to one another of different lengths or formed by a container bottom movable by means of the shaker drive which extends on the outlet side beyond the container area.

A litter cart that has been known for a long time has a relatively small ground clearance on the cart frame arranged container to which a shaking floor is assigned and on the outlet side is extended backwards over the container area. But is also with this spreader it is not possible to place the material in rows on the seed floor, as the shaking floor is relatively wide and can only be moved transversely to the direction of travel by the shaking drive, so that the Well spread uncontrollably on a wide path.

a seed drill with seed guide tubes running vertically from a seed hopper to the seed bottom,

^a 5 each of which is assigned a parallel fertilizer pipe and is connected at the upper end to a further container which is separate from the seed container. Also in this known machine, because of the high speed of fall, the

Saatguts the disadvantages already described above with regard to the danger of Besehädigangsgefahr for the germs of the Seed and its large spread on the seed soil ie purchase will be taken. Incidentally, the simultaneous sowing and fertilization of the agricultural knowledge

From an economic point of view it can hardly be tolerated, since the fertilizer falls on the seed.

The invention is based on the object of designing a device of the type mentioned at the outset in such a way that that even pre-germinated seeds without damaging possible germs or sprouts in exact rows is deposited on the seedbed. This is achieved by that * the dosing channel is arranged to be adjustable in height.

The inventive design of the device allows the metering channel regardless of their Slope to open in the immediate vicinity of the seed bottom, so that the material out of the metering channel is formally deposited on the seedbed. The good can therefore no longer be scattered and uncontrollably not be damaged even if it is pre-germinated and has very sensitive sprouts or Has germs.

Ler 11 of the shaking drive 6, 8 enable the distance between the metering channel 3 and its inclination and relative speed to the seed base 12 to be adjusted during the shaking strokes. The adjustment range of the adjusting screws 10 a, 10 & is chosen so that the outlet 3 α of the metering channel 3 can be lowered essentially down to the latter with a very slight inclination of the latter towards the seed bottom 12.

The device according to Fig. 1 to 3 points at a distance ίο in front of the metering channels 3 a furrow pulling device with ploughshares 13, behind which in the plow track each a disc 14 is arranged and is preferably designed as a planting wheel.

The shaking drive 6, 8 is on the stepless

Coordination of the drive setting with the speed controller 11 by means of a shaft 15 of a gear speed can drive the 16 deposited per unit of time, which is precisely dosed with a power take-off shaft and individual onions can be coupled to the towing vehicle. In the F i g. 4 and 5 is or tubers deposited at predetermined intervals in a similar to the device according to FIGS. 1 to 3, however. ^{oone planting} wheels trained device shown,

One embodiment of the invention is in the ao its metering channels 3 pointing in the direction of travel Drawing shown. In this shows. immediately behind the assigned ploughshare

In this context, it is also very advantageous when using a furrow pulling device when the metering chute has its outlet end pointing in the direction of travel directly behind this furrow pulling device is arranged. Because the crop is made directly behind the furrow pulling device If the discharge channel is rolled onto the bottom of the furrow, it can no longer be postponed when the furrows collapse again shortly after the furrow opening device.

If the device has an adjustable shaking drive, it is advantageous if the drive has a adjustable crank arm and / or a continuously variable transmission takes place. Through an appropriate

A device designed according to the drawing ■ is used to drop onions, tubers, seeds or other more or less coarse-grained items Good on seed soils and is equipped with a frame on which a to pick up the crop certain container 1 is arranged. In the exemplary embodiment, this has four outlet nozzles 2, each of which opens into a metering channel 3 arranged parallel to the direction of travel and with a slide 4 are equipped, through which the outlet cross-section can be changed.

Each of the metering channels 3 can be moved back and forth on the frame in the longitudinal direction by means of swings 5 stored and driven by a connecting rod 6, which is longitudinally adjustable via nuts 7 and articulated on the attacks the rear end of the channel and forms a shaking drive with an associated crank 8. Apart from the length adjustability of the connecting rod 6, the crank stroke can also be implemented by a Crank bolt 9 adjustable.

The swings 5 are connected to the frame of the device by adjusting screws 10 α, 10 &, which are in the Connection with a stepless speed control furrow pulling device are arranged.

In FIG. 6 shows a device with a further dosing chute 17 a ₅ arranged above the dosing chute 3, to which a further container 18, separated from the container 1, is assigned for receiving another type of material.
