description

The invention "relates to a device for distributing Fertilizers or improvers that come in powder or granule form present on the floor.

There are already known distribution devices that receiving and distributing material contained in a hopper mounted on an agricultural vehicle comprising a distribution member which, in the working position, extends perpendicular to the direction of displacement and that can fold open or fold back above the vehicle on which it is mounted. Generally exist such distribution organs of three parts, namely a fixed central part and two foldable back onto the central part Side panels.

Such devices have particularly high manufacturing costs and are not easy to use. In addition, the presence of the central part of the distribution organ hinders any separate control of the two side parts and therefore does not allow a different distribution of fertilizer on the right and the left To accomplish side of the device.

On the other hand, in each of the side parts, the amount of material to be distributed decreases as one looks at the outer one

709837/0839

The ends of the vehicle are approaching, and as a result, it is very difficult to uniformly distribute the fertilizer or the soil improver.

The object of the invention is to avoid these disadvantages by providing a simple device for distributing fertilizer or improvement means is created on the ground at a relatively low cost price, whereby these can fold back in the boom position so that the permissible profile dimension is not exceeded.

To achieve this object, the device according to the invention is used to distribute fertilizers or improvers the floor, which is characterized by the fact that it includes a distribution organ, which by a left ramp and a right Ramp is formed, which can assume a working position in which the distribution member is perpendicular to the direction of displacement of the supporting vehicle is present, and a rest position in which the organ is on both side edges of the carrying vehicle is folded back.

The fact that the ramps are folded back along the side edges of the supporting vehicle improves stability and the rigidity of the vehicle as a whole is essential.

According to a further feature of the invention, each of the left and right ramps carries means for conveying the the product to be distributed on the ground, each of these conveying devices being taken along individually by a device

709837/0 83 9

whose speed is isolated from the vehicle position of the carrying vehicle can be controlled.

In this way, if for any reason it is desired, it is possible to have a different distribution to bring about each side of the supporting vehicle.

You can use any equipment to bring about the conveyance of fertilizers, z. B. chain conveyor or scraper belt conveyor or an Archimedean snail that rotates in a sheet metal tube. Such a snail will either operated mechanically or by a hydraulic motor, the speed of which is controlled by a device known per se can be controlled. For economic reasons, it is particularly advantageous to use a commercially available, Archimedean snail commonly used for handling grains or fertilizers.

According to a further feature of the invention, the outer tube of the Archimedean snail is pierced by outlet openings, which are arranged so that a certain amount of the contained in the bore and under the influence of the rotation of the auger conveyed from the introduction opening to the end of the ramp Product is allowed to escape.

According to a further feature of the invention, the two are on top of each other following outlets separating the distance proportional to the throughput of the product, as they are for the same

709837/0839

openings of a comparative device, which was used under the operating conditions, was determined.

The flow rate of the material through the outlet openings depends on the degree of filling of the pipe, and therefore it increases regularly from the origin to the end of the ramp. On the other hand, it is sometimes desirable to have as great a uniformity as possible to achieve the distribution of the product on the floor, which is achieved by a suitable arrangement according to the invention can be. For example, you can set a maximum distance that is compatible with the quality of the work you want to do fix, which is the gap of the through hole near the feed point of each of the ramps, and then determine the other gaps between the holes by calculation according to the method given above. The openings can be closed by slides. According to a further feature of the invention, there are slides made of stainless steel.

According to a further feature of the invention, the device carries brackets or Haiteschellen to the slide in a to immobilize the predetermined position by suitable means.

This arrangement makes it possible to regulate the percentage of closure of the exit openings in a particularly simple manner.

According to a further feature of the invention, the brackets are arranged obliquely with respect to the axis of the slide, and they include a slot into which the lugs fixedly connected to the slides can slide so that a displacement the lugs parallel to the axis of the stirrups with a squat displacement of the slides parallel to them themselves brings, whereby a very precise regulation of the percentage of closure of the outlet openings is possible in this way is.

This arrangement enables extremely precise control of the degree of closure of the outlet openings, da, under the assumption that the axis of the lugs sliding in the bracket forms an acute angle α with the main axis of the slide, a shift d of the cleat, a shift d.sin α the Brings slide with it.

According to a further feature of the invention, the means are which enable the transfer of each ramp from the working position to the rest position, from an arm perpendicular to the Main axis of the ramps, one end of which is articulated on a ball joint mounted on the chassis of the supporting vehicle is attached and the other end rests on a rail, which the lifting of the whole for guiding over the wheels and allows the fenders, this arm is firmly connected to the chassis with the interposition of a role, as well from a tension system, which is on the one hand at a high

709837/0839

Funct of the supporting vehicle and on the other hand attached near the end of one or the other ramps, together.

This arrangement makes it possible on the one hand to close the ramps for their transfer from the working position to the rest position maneuver and on the other hand makes it possible to keep these ramps just as well in the working position as in the rest position. A safety beam can hold each ramp immobile as it moves.

According to a further feature of the invention, there is tension each ramp from a single cable or rope, which is around an orientable, on the upper part of the carrier vehicle fixed disc leads, wherein its length is adjustable and wherein at least one of its attachment points on the Ramp or can be regulated on the vehicle with the interposition of the disc.

According to a further feature of the invention, the pivotability of the arm formed by a ball joint, the ball of which is attached to the supporting chassis and the capsule of which is a includes latch making the ramp easy to pull out.

The invention is explained in more detail below with reference to the drawing, these only being relates to a right ramp, from which, however, the left ramp can be derived by simple symmetry considerations

709837/0839

- 12 can. In the drawing are:

Fig. 1 is a rear view of a device according to the invention for spreading fertilizers or improvers on the soil;

2 shows a detailed view of the lower surface of the sheet metal tube of the Archimedean screw from one of the ramps;

3 shows a plan view of the device; Figure 4 is a side view of the device.

In the figures, the ramp is shown in broken lines in the folded-back position.

In Fig. 1 is the device for distributing fertilizers or improvers on the ground, which the object of the invention represents a distribution organ formed by two ramps 1 which carry the material to be distributed which is contained in a hopper 2 mounted on an agricultural vehicle 3.

The ramps 1 can assume a working position, which is shown in solid lines, and a rest position, which is shown in dashed lines, the ramps 1 here on both sides of the side edges of the carrier vehicle 3 are folded back. This folded-back position is particularly advantageous because on the one hand it enables folding back the ramps of vehicles according to

709837/0839

Prior art to avoid upwards, whereby the stability of the whole of the device is improved and no impairments occur in the course of filling the hopper.

According to FIG. 2, each ramp consists of, for. B. an Archimedean Screw, which is not shown and which rotates in a sheet metal tube 10. This screw can be mechanical or by a hydraulic motor, the speed of which is controlled by means known per se, can be driven. Their length is as great as the suspension elements allow, which will be described in detail below. In general Case it is 5 or 6 m.

Along the lower dumbbell line of the tube 10 are circular openings 4- for the discharge of the fertilizer or improvers which are spread on the ground should be drilled in. These openings 4 have a constant diameter, which depends on the nature of the product to be scattered is adapted and generally between 10 to 30 mm amounts to. They are intended to contain certain amounts of the contained in the ramp 1 and under the influence of the rotation of the Archimedean screw to exit from the inlet opening 5 after the end 7 of the ramp conveyed product. The outflow of the product at the end 7 of the ramp 1 is completely free in order to avoid any risk of a jam.

709837/0839

It is particularly important to achieve as uniform a distribution as possible on the ground. Since the throughput of the Material through the outflow openings 4 is a function of the extent to which the ramp 1 is filled, it takes of course from the insertion opening 5 to the end 7 of the ramp 1. If you therefore have all openings 4 at the same distance would attach from each other, the floor surfaces, which are located under the areas of the ramp close to the inlet opening 5, a great deal more fertilizer or material than the bottom surfaces located under the end 7. To avoid this disadvantage, the openings 4 distributed in spaces proportional to the flow rate as determined for each opening. The regularity of the decrease in the throughput can be determined in particular on a test ramp, which with a comparable product is operated and which is fed according to the desired throughput. It will be a maximum distance compatible with the quality of the desired machining, generally of the order of magnitude set from 20 to 30 cm, this being the gap or Distance of the through holes in the vicinity of the feed point 5 of the ramp 1 is. The other spaces or distances of the Perforation are made by the calculation as a function of the observed flow rate, as previously described has been set.

709837 / 08.3 «

To other products like that to define the gaps To be able to use the product used or the distances of the perforation, an additional control of the throughput rate of the product to be scattered through the outflow openings 4 are provided. This control consists of rectangular Sliders 6, which can for example consist of stainless steel from a few centimeters wide and which on the Edge of the line of the through bores of the outlet openings 4 are arranged and displaced parallel to themselves in this way can be that they have the openings 4 more or less close. These slides 6 are held in the desired position with the help of small, metallic brackets 8, which are welded to the pipe 10, and they can be made immobile by means of clamping screws 9, for example. The brackets 8 are inclined with respect to the axis of the slide 6, arranged, and they form a bearing 11 in which Lugs 12, which are connected to the registers 6, can slide. The lugs 12, for example parallelepiped May have shape forming an acute angle with the main axis of the slide. The unit slide 6 - catch 12 is arranged such that the edge or the edge of the slide 6, in an end position of the lugs 12, with the edge of the outflow openings 4 is flush. The displacement of the lugs 12 in the bracket 8 brings about a distance d parallel to their main axis a displacement of d.sin α of the slide in the direction perpendicular to the axis of the ramp 1 with it, whereby a partial Closing or opening of the openings 4 of the ramp 1 caused

709837/0839

will. This arrangement therefore enables a special precise regulation of the degree of closure of the openings 4 to be obtained by "stepping down" the movement of the lugs 12. The position of the slide 6 can be determined with the aid of a scale applied to the edge of the lugs 12.

In FIGS. 1, 3 and 4, each ramp 1 can move out of its working position (shown in solid lines) in their rest position (shown in dashed lines) with the aid of a Arm 13 are transferred perpendicular to the main axis of the ramp 1. This arm 13 is articulated at one of its ends on a ball joint 14, the ball 15 of which is attached to the supporting chassis and whose capsule 16 carries a lock that makes the ramp easily replaceable.

The arm 13 rests on the other side on a spherical rail 17 with the interposition of a roller 18, the Rail 17 guides the movement of arm 13 and is firmly connected to the chassis. A system of tension wires 19, the one hand at a high point 20 of the carrier vehicle 3 and on the other hand is attached in the vicinity of the end 21 of the ramp 1, the ramp 1 holds in the desired position. The tension 19 consists of a single cable 22 which is connected around an orientable disk 23 which is attached to the upper part of the carrier vehicle 3 is attached, leads, and the length of which is adjustable. At least one of the attachment points of the cable 22 to the ramp

709837/0839

with the interposition of the disk 23 eats itself also adjustable.

All information and characteristics disclosed in the documents, in particular the spatial design are considered essential to the invention claimed insofar as they are new to the state of the art individually or in combination.
