The device according to the invention shown in the figures has a frame which essentially consists of a curved frame beam 1 which is provided with an inclined arm 98 and strips 99 and 100, with which the device is attached to the lifting device of a tractor. On the lower side of the frame beam 1 is provided with feet 101 with which the device can rest on the floor. The ends 2 and 3 of the frame beam 1 are parallel to one another at the same height and are connected to one another by two strips 4 and 5. The ends 2 and 3 'and the strips 4 and 5 carry a container 6 which is provided with two strips 7 and 3, which can be arranged on one side of the strip 4 each. At the front of the container 6, a locking pin 9 is attached to a support member 6k, which can be inserted into a hole 10 of the strip 5, whereby the container 6 is fastened to the frame. Below the container 6 is a spreading member in the form of an ejector disc 11, which is provided with a central part 12 in the form of a disc, on the circumference of which blades 13 are attached which is attached to a beam 16 connected to the beam 1. The spreading element 11 is driven by a horizontal axis 102 via a gear drive located in a box 17, wherein it _{rotates about the vertical J 0} axis of rotation 18. The lower wall part of the container 6 can, as is illustrated in FIGS. 1, 2 and 3, be formed by a cylindrical "» »x ring 19 on which the spreading member 11 rests, which the

Form the container and through which the material from the container 6 to the Spreading member 11 can be supplied. The recesses 22 to 24 are

ο designed identically and distributed within an angle 25 of approximately 90 about the axis of rotation 18 of the spreading member 11. Each recess has the shape of a trapezoid, as is described in more detail below for recess 23. The recess 23 has two parallel sides 26 and 27, of which the side 2J is the base and through the lower edge of the ring

19 and the disc 12 is formed, on which the ring 19 to rest *. ■ -. In addition, the recess 23 has two inclined sides 28 and 29, of which the side 29 runs perpendicular to the sides 26 and ZJ , so that the base angle 27B is 90. The base angle 27A lying between the side 28 and the base 27 is approximately 70 °. In this exemplary embodiment, the side 27 has a length of approximately 30 mm, that is to say approximately one seventh of the ring diameter, the clear width 30 of which is approximately

20 mm. amounts to. The side 29, which is equal to the height of the recess, is about 60mm. long, while the length of side 26 is about 15 nmu amounts to. The height 29 is therefore twice the base side 27 · um to secure the ring 19 against rotation around the cylindrical wall part 21 it is provided with an adjustment mechanism, which is connected to the ring 19 attached tongues 31 and 32 can be connected

. mechanism has a curved rod 33, the ends of which with the Tongues 31 and 32 are connected. An arm 34 is attached to the rod 33, the free end of which is provided with a pin 35. The pin 35 can be inserted into one of the Löoher 36, which is in one on the frame beam 1 attached beam 37 are attached. When the pin is 35 in Another hole 36 is inserted, the ring 19 with the recesses 22 to 24 rotated about the axis of rotation 18 and fixed in a different position.

are attached to a ring 41. The ring 41 rests on the tongues 31 to and 32 and on a pin 42 attached to the ring 19 (Figs. 1 and 2) I ~ and is provided with a fixing member through which the plates 38 "^ to 40 can be determined in different positions on the ring, so that

O the size of the discharge openings of the container is adjustable. Every

_OT discharge opening is in this way through one or more ° sides of one of the recesses 22 to 24, through an edge of one of the

Closure plates 38 to 40 and through the disc 12 the spreading member limited. At the maximum discharge opening, the edge of the closure

'Plate with side 29 of the recess to cover. To firmly bind the fishing link to the ring 41, the latter is provided with two tongues. The fixing member contains an arm 44 'which is attached to the tongues 43 with a horizontal pin 45. The arm 44 has at one end a graduated plate / \ 6 which is provided with short arms 46A at its end. The plate 46 can be clamped against the arm 34 by a clamp 47 attached to this arm which is lockable by a wing nut 48 and has a pointer 47A which cooperates with the scale on the plate 46.

The ring 19 can be replaced by a ring 49 in which three Recesses are provided which are designed differently than the recesses 22 to 24 in the ring 19 (^ ig · 5 to 8). The ring 49 has three ^ 5ö5 and 5 ^, each having the shape of a right-angled

Have triangles and in the same way within an angle 25 of 90 around the axis of rotation 18 of the spreading member 11 are distributed like that Recesses 22 to 24 in the ring 19 · The recesses 50 to 52 have same shape. As shown in detail for the recess 51, have an inclined side 53t, a vertical rectangular side 54 and a base 551 which is formed by the disc 12 on which the Ring 49 rests. The base 55 of these openings is of the same size like the base of the openings 22 to 24 · The height of the recesses 50 however, through 52, which is equal to the length of side 54, is essential smaller than the height of the recesses 22 to 24 and in this exemplary embodiment is about 23 mm., so that the base 55 is 1.4 times as large is, so is almost 1 ^ times the height 54 of these recesses. The base angles 55B and 55A are 90 and 35, respectively. The ring 49 is to prevent rotation around the cylindrical wall part 21 of the container 6 with an adjusting mechanism in the same way as the ring I9 provided. The ring has tongues 57 and 5ß for this purpose The tongues 57 and 58 are arranged in such a way that the individual parts * ~ of the adjustment mechanism for the ring 49 exactly like that of the adjustment

«- mechanism for the ring I9 can be designed; they are therefore 6 and 7 are not shown individually.

The recesses 50 * 51 and 52 can be more or less wide co terminated by closure plateso9j ° ύ and ofV, which at o a ring 62 are attached. The discharge openings for the material are thereby through the recesses 50 to 52 or by those Parts of the recesses formed which are not from the closure plates

In the latter case, each discharge opening is delimited by the side 53 of a recess, by an edge of the relevant closure plate and by a part of the base 55. When the recess is completely free, each discharge opening is delimited by the sides 53 and 54 and the base 55, whereby the side 54 can coincide with an edge of the relevant closure plate. The ring 62 does not rest on the ring 49, like the ring 41 on the ring 19. The ring 62 surrounds the ring 49 in such a way that it rests independently of the ring 49 ^with its weight on the disc 12 of the spreading member 11 rests. On the side facing away from the closure plates 59 to 61, the ring 62 is provided with a support 49A, which prevents the ring 62 from lowering at an angle and from being clamped against the ring 49. The ring 62 surrounds the part 63 of the outside of the ring 49j, the part 63 and the inside of the ring 62 being precisely matched to one another. In order to be able to bring the closure plates 59 to 61 into a certain position in relation to the recesses, the ring 62 is provided with two tongues 64 which can be connected to a fixing member which is designed like the fastening member of the ring 41. The tongues 64 are arranged in such a way that the individual parts of the fixing member can be exactly the same as those of the ring 41; they are therefore not shown further in FIGS. 6 and 7 and in FIG. 5 they are denoted by the same reference numerals. The ring 49, like the ring 19, is centered around an elevation of the disk 12 of the spreading member 11 formed by the disk 20.

To enable simple manufacture of the device and easy assembly of the container on the frame, a space of a few millimeters is provided between the outer diameter 65 of the cylindrical part 21 of the container 6 and the inner diameter 30 of the ring 19 or the inner diameter of the ring 49 so that the part 21 does not have to be exactly concentric to the axis of rotation 18 of the spreading member in order to achieve a good connection of the part 21 to the ring J ₀ 19 or the ring 49. The outer diameter 65 of the ¹ ^ cylindrical part 21 of the container 6 can now, for example, 195. be, "*» * while the inner diameter of the ring 19 or the ring 49 i ⁿ

cd this example 200 mm. amounts to. However, there is no material from the

_σ) container can get between the part 21 and the ring I9, the ° ring 19 is provided with an edge 66 on the inside. This edge lies below the cylindischeryreiles 21 of the container 6. In general, it is sufficient to make the inner diameter of the edge 66 smaller than

to make the outer diameter of the part 21. Preferably, however, the edge 66 has an inside diameter which is smaller than the inside diameter of the cylindrical rope 21. The edge 66 consists of a strip which is perpendicular to the inside of the ring 19 and assumes an angle of approximately 270 about the axis of rotation 18, with the recesses 22 to 24 no edge is present. Since the material is discharged through the recesses 22 to 24, the possibility that it will get in the vicinity of these openings between the part 21 and the ring 19 is generally low.

The ring 49 is provided with a rim 67 to prevent Material from the container between the part 21 and the ring 49 gets. The edge 67 has an inner diameter 68 which is smaller than that Inner diameter 69 of the cylindrical wall portion 21 of the container. However, the edge 67 extends over the entire inside of the ring 49 » since the recesses 50 to 52 are lower than that above the Disc 12 lying edge 67.

The edges 66 and 67 can be used with success particularly when a shovel 70 acting on the material is used in the container, which, as can be seen from FIG rises behind. As a result of the rotation of the shovel, the material can be pushed somewhat upwards, so that the possibility of it getting between the ring 19 or the ring 49 and the wall part 21 of the container 6 is greater iet ale without the use of the shovel 70f acting on the material on which a member 73 acting on the material can also be attached (FIG. 1).

The bottom surface of the container 6, which is formed by the disc 20, is provided with two edges 74 and 75 which act on the material and which run backwards from the axis 14 against the direction of rotation 72 of the spreading member and extend to the circumference of the disc 20 extend. These edges 74 and 75, which have only a small height J ₀ promote that the material to be spread through the expedient of * ~ the recesses 22 to 24 or 50 to 52 formed discharge apertures "*" * ". is discharged, even if the device without affecting the material

The ring 19 », which rests on the ejector disk 11 and whose weight is increased by the weight of the ring 41 and the plates 38 to 40, has an edge 76 at the lower end which is narrower than the thickness of the ring 19. This narrow edge J6 is obtained in that the ring 19 is sawed off on the lower side and on the outside of the part 77 (Pig. 2). Similarly, the ring 49 is provided at its lower end with an edge 78 which is also narrower than the thickness of the ring 49.This edge 78 is obtained because the part 79 of the ring 49 is beveled (Figs. 7 and 8 ). The ones not on disk 1 ?. resting closure plates 38, 39 and 40 are provided at the lower end with edges, the width of which is equal to the thickness of these plates. The closure plates 591 60 and 61, which cooperate with the ring 49, are, however, similar to the ring 49 at the lower end with edges 80 which are narrower than the thickness of the plates, the edges 80 by beveled parts 81 of the plates 39 to 39 61 are formed. Due to the narrower design of the lower ends of the rings 19 and 49 and the closure plates 59 to 61, the pressure with which these rings and the plates rest on the disc 12 per unit of surface area increases, so that the possibility of the material underneath it Rings and plates falling out of the container is reduced.

The fiing 19 with the recesses 22 to 24 and the ring 49 mrfc the recesses 50 to 52 can be used as desired? When using the ring 19, the discharge openings of the first shape are available for discharging the material from the container and when using the ring 49, those of the second shape are available such as artificial fertilizer, whereby the device J ₀ should not spread excessively small amounts of material per unit of length to be covered. The ring 49 "" it "-" the second discharge opening is particularly useful when the device is a small amount per unit of length to be covered

In the embodiment shown in FIG. 9, the cylindrical wall part 21 is surrounded by a ring 83 which, like the ring 19, rests on the throwing disc 11. The ring 83 is provided with two recesses 84 and 85, which are also ^mi the axis of rotation 13 offset from each other by an angle of 90 '. The recesses 84 and 85 are of identical design and each have a base 86 which is formed by the lower edge of the ring and the disk 12. A side 87 resting on the base 86 together with this forms a base angle 88 of approximately 35 °. The side 87 merges into a second side 89 which forms an angle of approximately 70 with the base 86. Each recess is also provided with a side 91 which is parallel to the base 86 and a side 92 which is perpendicular to the sides 91 and 86. The recesses 15 and 85 can be covered to a greater or lesser extent by spine plates 93 and 94, which are fastened to a ring 95. The ring 95 rests on two tongues 96 and 97 and on a pin attached to the other side of the ring Ö3, which pin is not shown. Kit the tongues 96 and 97 can * uf. In the same way, a setting mechanism (not shown) can be connected which corresponds to the setting mechanism connected to the tongues 31 and 32 of the ring 19. The ring 95 can be fixed to the ring 83 in the same way as the ring 41 to the ring 19.In this exemplary embodiment, the recesses can have a size for spreading larger amounts of material per unit surface area of the soil, which extend from the base 86, the sides 87, 89 and 9I and an edge of the closure plates is limited, this edge with the side 92 can come to cover. It can be seen that in the case of a partial closure of the recesses, the side 86 and the side 91 can be partially or fully or partially covered by the closure plates. In order to spread smaller amounts of material per surface unit of the soil to be worked, the part of the recesses which is delimited by the sides 89, 91 and 92 and a part of the base 86 can be covered. The discharge openings can be encompassed by part of the base 86, the <t> side 67 and an edge of the closure plates. This results in discharge openings which can have the same size as the discharge openings which are formed by the recesses 50 to 5 ² in the ring 49. <

fx> Although the recesses gj ~ _{Ό are} always provided in the inner ring 19, 49 or 83 in the embodiments described, they can also be attached to the shapes mentioned in an outer ring, which, for example, the S ring 41 with the plates 3o to <iü replace. In doing so, these recesses

are, with therechteoköffmangen in the inner ring are so large that the Recesses can be completely free around the discharge openings for discharge of the material to form.
