The invention relates to a device for scattering granular or powdery material, in particular Fertilizer, in which the fertilizer is fed from a container to a spreading element; by doing Container is arranged to achieve a proper removal of material, a rooting member that during the Operation is movable relative to the container and has lugs which are arranged on an intermediate part are.

In known spreading devices of this type, the rooting member is firmly clamped at both ends and designed according to the shape of the walls of the agitator tank. The rooting element is central guided and slides directly along the wall of the container so that no material is on the wall can stick. The movement of the root does not loosen the inside The material located in the container is reached because the approaches of the Wühl member as a result of their fixed clamping cannot perform a corresponding, for example inwardly directed movement. Farther is the rooting element in this known device in the lower, narrow outlet part of the container clamped and stored so that the free space in front of the outlet opening is reduced and the promotion of the material is thus hindered.

Furthermore, a device of the type mentioned is known in which the approaches of the rooting member with their one end protrude freely into the container, while only their other end on the intermediate part is arranged, which in turn with an upwardly guided, with the drive in articulated Connected arm is connected. The approaches are in this known rooting member of the im lower part of the container located attachment point facing upwards. Since the free ends are a have some mobility, they can move the material in the upper part of the container during operation loosen, but there is a risk that the material will get stuck in the lower part of the container due to its own weight. In this area the movement the rooting member or the free ends of the approaches no longer affect the movement of the material.

With the inventive design of the rooting member is to be achieved that the material also in the lower part of the container can be held loosely.

Netherlands of February 3, 1958 (224 622) - -

ment of a proper material removal a rooting member is arranged, which is relatively during operation can be moved to the container and has lugs that protrude freely into the container at one end, while its other end is arranged on an intermediate part, which in turn with an upward guided, with the drive in an articulated connection arm, the invention consists in that the free ends of the lugs protrude from the fastening parts down into the container. The rooting member, whose arm, which is guided upwards, is articulated to the drive, as mentioned, moves through the material during operation and decreases as a result of the articulated connection in a manner known per se different layers. The lower free ends of the lugs move here now in such a way that a good loosening of the material is achieved, especially in the area of the container in which the material can get stuck due to its own weight.

In a known fertilizer spreader with a storage container divided to accommodate two types of material a rooting member is provided in one container compartment, the one stored in the other container compartment Stirring set in oscillating motion. This stirring rod also protrudes with its free end down into the relevant container compartment. Because it

however, if it is a single rod-shaped stir bar, its effect is local.

In another known fertilizer spreader, the rooting member has two lugs attached on one side, which are also effective near the ground. However, the approaches are rigidly connected to their drive shaft and run horizontally from their attachment point after a short bend, so that they also can only have a loosening effect near the ground.

It is also known in kitchen machines to form kneading hooks as approaches that have free ends and protrude from the fastening point down into the kneading container. The problem is with These known machines, however, are different, since it is not a question of material from the kneading container discharge and ensure that the material continues to flow, but rather knead or knead the material to mingle.

- In a device of the type according to the invention, in which the intermediate member is circular, are in a further embodiment of the invention, the approaches to the circumference of the intermediate member, which is in the Central position of the rooting member is almost horizontal, attached. This ensures that the shape of the Rifling member of the shape of the mostly funnel-shaped lower container part can be adapted well. Appropriate are for this purpose also the approaches to their lower end inwardly on the arm of the Rooting member too directed.

The intermediate member carrying the approaches is connected to the drive via the support arm in such a way that the approaches are rotatable in a manner known per se about the longitudinal axis of the rooting member. This will achieved a particularly useful additional possibility of movement of the approaches. These approaches are expediently made of resilient material in a manner also known per se.

The approaches of the rooting member can be designed in such a way that they have a first upwardly directed Have part and then over a bend in the downward and tapering towards the support arm Skip part. In each case two approaches can be connected to one another at their lower ends be.

The invention is described below with reference to an embodiment shown in the drawing explained in more detail. It shows

Fi g. 1 shows a section through a container and a spreading disc arranged underneath this container on which the rooting element is mounted,

Fig. 2 is a section through the attachment of the rooting member on the axis of the lens.

The spreading device has a container 1, which consists of a pyramidal part 2 and a cylindrical part 3 consists. Below the container 1, a rotatable diffuser 4 is arranged, which covers the bottom of the container. Between the disc 4 and the cylindrical part 3 of the container 1 is a cylindrical one Ring 5 arranged, which rests on the disc 4 and with its upper end the cylindrical Part 3 of the container encloses. On the disc 4 scattering arms 6 are arranged over the disc protrude. In the ring 5, several openings 7 are provided for the removal of the material.

The digging member 8 arranged inside the container is mounted on the disk 4. The disc carries an axis 10 (FIG. 2), the center line of which forms the axis of rotation 9. On the axis 10 is a socket 11 arranged, which is secured against displacement and rotation by a pin 12. The socket 11 carries a plate 13, in the recess 14 of which the lower end of the arm 15 is spaced from the axis of rotation 9 is stored. The plate 16 welded to the arm 15 and the one with the aid of the split pin 18 attached ring 17 secure the arm 15 against falling out.

ίο At the top of the arm 15 is a circular one Plate 19 attached. In the illustrated central position of the arm 15, this plate is approximately horizontal. On the outer edge of this plate several lugs 20 are attached, which evenly over are distributed around the circumference of the plate. The free ends of the lugs 20 protrude down into the container, and in the embodiment shown, two lugs are connected to one another at their lower ends 26 tied together. Each approach extends from the plate

ao 19 from with a part 21 initially at an angle upwards and passes over a bend 22 into a part 23 which runs in the direction of the arm 15. Part 23 is close to the container wall. All parts 23 of the approaches 20 are within one imaginary conical surface. In the central position of the rooting member, the parts 23 run parallel to the container wall.

In the embodiment shown, six lugs 20 are provided, only four of which are shown are. For the other two approaches, the recesses 24 and 25 are provided in the plate 19, in where these approaches can be attached. The maximum height extension 27 of the approaches corresponds about half the height 28 of the entire rooting member.

When the lens rotates about its axis of rotation 9, the lower end of the arm 15 moves up a circular path around this axis. The rooting member 8 moves through the in the container Material. As a result of its arrangement in the recess 14, the arm 15 can around hinge axes tilt that are perpendicular to the center line of the recess 14 and lie in a plane that is perpendicular is on the axis of rotation 9. The resistance of the material in the container to the lugs 20 is usually so large that the arm 15 always rotates in the recess 14. Since the top of the Arm 15 can not always follow the movements of the lower end on a parallel path, lead the resilient approaches from an oscillating movement.

In the embodiment shown, the arm 15 is designed as a rod. Of course he can too consist of flat or profile material. The articulated connection of the arm 15 with the drive can also be carried out differently. It is only essential that a relative movement between the rooting member and the container is achieved.
