Description

The invention relates to a distribution device for distributing liquids containing solids, in particular liquid manure. Furthermore, the invention relates to a perforated blade for a distribution device and a use of a perforated blade.

A typical area of application of such distributor devices is in agricultural technology, where many applications involve distributing liquids that carry solids from one line to several lines, for example to use liquid manure as a nutrient reservoir via a drag hose linkage or a trailing shoe linkage on a field.

A fundamental problem that occurs with such distribution devices is based on the fact that the solids-containing liquid has to be distributed from a feed line with a large cross section to a plurality of feed lines, each with a small cross section, due to the system. Due to the solids in the liquid, there is a risk of blockages in the small cross-sections in this system-related process. It is known in principle to integrate a cutting device into distribution devices for liquids containing solids in order to solve this problem. The solids in the liquid are comminuted by such a cutting device, which reduces the risk of blockages in the small passage cross-sections in or behind the distributor device. Out of EP 2 850 928 B1 a cutting device integrated into the distributor device is known, which has cutting knives which, in cooperation with a hole knife plate, exert a shearing effect on the solids when they pass through the outlet openings of the hole knife plate. Here, a cutting blade of the cutting device is moved relative to the hole blade plate in order to produce this shearing effect. The outlet openings in the perforated blade plate correspond to the openings in the connection pieces of the distributor device.

Another problem that occurs with distribution devices of the type mentioned at the outset is that in such distribution devices, when the cutting device moves along the perforated knife plate, a negative pressure is generated in the outlet openings or in the hoses connected to the connecting piece. Repetitive relative movements between the cutting device and the outlet openings of the perforated cutter plate can result in pulsating pressure fluctuations, which can make precise dispensing of the liquids containing solids more difficult. For this reason, distribution devices are typically equipped with a system for air replenishment, which ensures that when negative pressure occurs, air enters the distribution chamber via air inlets, thereby equalizing the pressure. Such air suction is off, for example EP 2 850 928 B1 and from EP 3 175 696 A1 famous.

However, various problems can arise with such air replenishment. For example, in certain applications there may be an overpressure in the distribution chamber, as a result of which the liquid containing solids escapes from the distribution chamber via the system for air replenishment, for example via one or more air replenishment nozzles. Such an overpressure can occur, for example, in the case of an application below the surface, in particular in the case of an injection application into slits, since in this case a high back pressure can arise in the hoses. Even when the hose is switched off, especially with the so-called "drop stop", the liquid containing solids can accumulate, which in turn can lead to the liquid containing solids escaping from the distribution chamber via the system for air replenishment. Furthermore, the liquid containing solids can escape from the distributor chamber via the system for air replenishment even when individual hoses are switched off, in particular with so-called “section control”.

The object of the invention is therefore to provide an improved solution which addresses at least one of the problems mentioned. In particular, the object of the invention is to provide a distribution device in which an undesired escape of liquid from the distribution chamber is prevented and at the same time precise and constant dispensing of the liquid is made possible.

According to a first aspect, the object mentioned at the outset is achieved by a distribution device for distributing liquids containing solids, in particular liquid manure, comprising a distribution chamber with an inlet opening which opens into a chamber interior of the distribution chamber, the distribution chamber having a first wall, in particular a first end wall has a first connecting piece and several further connecting pieces, a first perforated blade plate with a first outlet opening, which connects the chamber interior with the first connecting piece, and several further outlet openings, which connect the chamber interior with the several further connecting pieces, a first cutting blade which has at least one cutting edge abutting against the first die plate and movable relative to the first die plate, a cutter drive shaft rotatable about a drive shaft axis is mounted and is coupled to the first cutting blade, so that when the blade drive shaft rotates about the drive shaft axis, the first cutting blade is moved on a path of movement relative to the first perforated blade plate, characterized in that the path of movement runs in such a way that the first cutting blade is on the movement path sweeps over the first outlet opening of the first perforated knife plate and the first perforated knife plate has a first outlet opening with an outlet opening cross section, the first cutting knife has a contact surface section resting on the first perforated knife plate, the outlet opening cross section and the contact surface section being dimensioned such that the contact surface section does not exceed the outlet opening section in any position of the first cutting blade on the path of movement completely closed, so that there is always a fluid connection between the first connecting piece and the chamber interior via which it ste outlet opening exists.

The distribution chamber is preferably designed to accommodate liquids containing solids. The inlet opening is preferably an opening in the distribution chamber through which a liquid containing solids is introduced into the distribution chamber, preferably by means of a connected hose. Liquid containing solids can be discharged from the distribution chamber and discharged via the connection pieces, preferably through hoses connected to the connection pieces.

The first perforated blade plate can in particular be designed as a perforated blade disk. The first hole knife plate is preferably arranged on the first wall of the distribution chamber. The first die plate has a first outlet opening and a plurality of other outlet openings. The first outlet opening and the plurality of further outlet openings are preferably arranged in a circle on the die plate. The first outlet opening and the plurality of further outlet openings are preferably equidistantly spaced from one another. The first outlet opening and the several further outlet openings preferably have an oval or slot-shaped or circular contour.

The drive shaft axis is defined as a virtual line that runs along the axis of rotation of the blade drive shaft and which represents the axis of rotation of the blade drive shaft. The blade drive shaft is preferably connected to the first cutting blade via a rotor, the rotor preferably being a component which is connected to the first cutting blade and the blade drive shaft. The rotor can preferably be set in motion, as a result of which the first cutting knife, which is preferably connected to the rotor, moves on a movement path. The knife drive shaft and the rotor can also be designed integrally. In particular, the rotor can also have a blade drive shaft, in which case the rotor can preferably be connected directly to a drive motor. A movement path is to be understood, for example, as a circular path, in particular a circular path, or an eccentric path. The first cutting blade has at least one cutting edge which bears against the first hole blade plate. The first hole cutter plate is preferably a plate which is flat on the side facing the distribution chamber and has a plurality of openings through which the fluid can flow from the distribution chamber to the connecting piece. On the side facing the first cutting blade, these openings form opening cutting edges through their edge. The cutting blade is moved relative to the first die plate and thereby effects a cutting action by shearing the cutting edge of the cutting blade at the aperture cutting edges of the apertures in the first die plate.

In every position of the first cutting blade on the path of movement, there is a fluid connection between the first connecting piece and the interior of the chamber via the first outlet opening. During operation, there is preferably a fluid connection between the first connecting piece and the chamber interior via the first outlet opening at all times. This is preferably achieved in that the first cutting blade is designed in such a way that it does not interrupt the fluid connection between the first connecting piece and the chamber interior via the first outlet opening in any position of the first cutting blade and/or at no time during operation.

The outlet opening cross section is to be understood in particular as the cross section of the outlet opening. The configuration that the outlet opening cross-section and the contact surface section are dimensioned such that the contact surface section does not completely close the outlet opening section in any position of the first cutting blade on the movement path means that the outlet opening cross-section and the contact surface section are dimensioned such that the contact surface section Outlet opening section in each position of the first cutting blade on the movement path either not or only partially closed. The outlet opening section is preferably partially closed in some positions of the first cutting blade and the outlet opening section is not closed at all in some other positions of the first cutting blade. In particular, will the outlet opening section is not completely closed in any position of the first cutting knife.

The present invention offers the advantage that existing solids can be crushed by means of the first cutting blade and blockage by solids can thus be avoided and at the same time no strong negative pressure is generated by the relative movement between the first cutting blade and the first perforated blade plate. The function of the cutting knife can thus be fully utilized in an advantageous manner without negative pressure changes occurring as a result. Thus, liquids containing solids can be dispensed precisely and evenly with the distribution device described, and high distribution accuracy can be achieved.

Furthermore, the invention offers further advantages compared to known devices in that no air replenishment is necessary, since no strong negative pressures are generated in the distribution chamber or in the hoses connected to the distribution chamber. In this way, an undesired escape of liquid from the distribution chamber, for example in the event of excess pressure in the distribution chamber, can be avoided by a system for air replenishment.

It is particularly preferred that in every position of the first cutting blade on the path of movement there is a fluid connection between each of the several further connecting pieces and the chamber interior via the several further outlet openings.

Preferably, in every position of the first cutting blade that the cutting blade can assume on the movement path, there is a fluid connection both between the first connecting piece and the chamber interior via the first outlet opening and between the several further connecting pieces and the chamber interior via the several further outlet openings. During operation, there is preferably at all times a fluid connection both between the first connecting piece and the chamber interior via the first outlet opening and between the several further connecting pieces and the chamber interior via the several further outlet openings. This can be achieved in particular by designing the first cutting blade in such a way that it does not interrupt the fluid connection between the connection piece and the chamber interior via the outlet openings in any position of the first cutting blade and/or at no time during operation.

Such a configuration offers the advantage that existing solids can be crushed by means of the first cutting blade and blockage by solids can thus be avoided and at the same time the first cutting blade does not generate a strong negative pressure at any of the outlet openings or at any of the connecting pieces liquids containing solids are applied precisely and evenly and a high level of distribution accuracy is achieved.

According to a preferred embodiment it is provided that in no position of the first cutting blade on the path of movement is the first outlet opening completely covered, in particular by the first cutting blade.

When the first cutting blade rotates in the chamber interior on the first perforated blade plate, the first outlet opening is preferably not completely covered by the first cutting blade in any position that the first cutting blade can assume during the rotation. Thus, in an advantageous manner, there can always be a fluid connection between the chamber interior and the first connecting piece, as a result of which undesired negative pressures in this area can be avoided.

Furthermore, it is preferred that in no position of the first cutting blade on the path of movement are the several further outlet openings completely covered, in particular by the first cutting blade.

When the first cutting blade rotates in the chamber interior on the first perforated blade plate, the several further outlet openings are preferably not completely covered by the first cutting blade in any position that the first cutting blade can assume during the rotation. Thus, in an advantageous manner, there can always be a fluid connection between the chamber interior and the several further connecting pieces, as a result of which undesired negative pressures can be avoided.

Furthermore, it is preferred that the first cutting blade partially, in particular not completely, successively covers the first outlet opening and the several further outlet openings during a movement on the movement path.

If the first cutting blade moves relative to the first perforated blade plate and thus relative to the first and several other outlet openings, then it is preferred if the outlet openings are not covered by the first cutting blade over the entire area of the outlet opening.

According to a preferred embodiment, it is provided that the first cutting blade has a length that extends in the radial direction and a width that extends in the circumferential direction, the width of the first cutting blade being smaller than the dimension of the first outlet opening in the direction of the Path of movement over the first outlet opening, in particular in the case of round outlet openings, is smaller than the diameter of the first outlet opening and/or each of the plurality of further outlet openings.

This ensures that the outlet opening cross section and the contact surface section are dimensioned in such a way that the contact surface section does not completely close the outlet opening section in any position of the first cutting blade on the movement path, so that there is always a fluid connection between the first connecting piece and the chamber interior via the first outlet opening.

The width of the first cutting blade preferably extends parallel to the direction of the movement path and/or in the circumferential direction. The length preferably extends in the radial direction and/or orthogonally to the width of the first cutting blade. The first cutting blade preferably has a width that is smaller than the extent of the first outlet opening in the circumferential direction. As a result, it can be achieved in an advantageous manner that the first outlet opening cannot be completely covered by the first cutting blade.

In a particularly preferred embodiment, the distributor device comprises a plurality of cutting knives, each of which has at least one cutting edge which rests against the first hole-knife plate and can be moved relative to the first hole-knife plate, the knife drive shaft being coupled to the plurality of cutting knives, so that when the knife drive shaft rotates moving the plurality of cutting blades relative to the first hole blade plate about the drive shaft axis.

The distributor device preferably comprises three cutting blades. A different number of cutting blades can also be provided, for example two, four, five or six. The cutting knives preferably rest against the perforated knife plate in each case, in particular with a cutting edge. The plurality of cutting blades are preferably of the same design, in particular like the first cutting blade. The multiple cutting blades may be equidistantly spaced from each other. The multiple cutting blades may also not be spaced equidistantly from each other.

Further, it is preferable that each of the plurality of cutting blades has a length extending in the radial direction and a width extending in the circumferential direction, the width of each of the plurality of cutting blades being smaller than the dimension of the first outlet opening in the direction of the Path of movement over the first outlet opening, in particular in the case of round outlet openings, is smaller than the diameter of the first outlet opening and/or each of the plurality of further outlet openings.

This ensures that the outlet opening cross section and the contact surface section are dimensioned in such a way that the contact surface section does not completely close the outlet opening section in any position of each of the cutting blades on the movement path, so that there is always a fluid connection between the first connecting piece and the chamber interior via the first outlet opening.

The configuration that the outlet opening cross-section and the contact surface section are dimensioned such that the contact surface section does not completely close the outlet opening section in any position of each of the cutting blades on the movement path means that the outlet opening cross-section and the contact surface section are dimensioned such that the contact surface section Outlet opening section in each position of each of the cutting blades on the movement path either not or only partially closed. The outlet opening section is preferably partially closed in some positions of each of the cutting blades and the outlet opening section is not closed at all in some other positions of each of the cutting blades. In particular, the outlet opening portion is not completely closed in any position of each of the cutting blades.

The width of each of the several cutting knives preferably extends parallel to the direction of the movement path and/or in the circumferential direction. The length of each of the several cutting blades preferably extends in the radial direction and/or orthogonally to the width of the cutting blade. The plurality of cutting blades preferably each have a width that is less than each circumferential extent of the outlet openings. This can be achieved in an advantageous manner that the outlet openings can not be completely covered by the multiple cutting blades.

Furthermore, it is preferred that the chamber interior of the distribution chamber is designed to be airtight with respect to the area surrounding the distribution chamber.

Airtightness between the chamber interior and the distribution chamber is to be understood in particular as meaning that there is no air connection between the surroundings of the chamber and the chamber interior. In particular, it is preferred if no air replenishment is provided or takes place via a system for air replenishment.

In this way, it can be avoided in an advantageous manner that liquid escapes from the chamber interior in the event of excess pressure in the chamber interior.

It is even more preferred that no air is supplied to the chamber interior of the distribution chamber. There are preferably no air supply nozzles provided.

Furthermore, it is preferred that the first outlet opening extends from a first end face of the first perforated blade plate facing the chamber interior to a second end face of the first perforated blade plate facing away from the chamber interior.

Preferably, the first perforated blade has a, preferably constant, thickness that corresponds to the distance between the first end face of the first perforated blade plate and the second end face of the first perforated blade plate. The first cutting blade and optionally the several additional cutting blades are preferably in contact with the first end face of the first perforated blade plate.

Furthermore, it is preferred that the first outlet opening is larger in the area of the second end face than in the area of the first end face.

The first outlet opening preferably increases in size from the first end face to the second end face. Particularly preferably, the first outlet opening runs conically from the first end face to the second end face.

Such a configuration of the first outlet opening offers the advantage that the increasing cross section results in acute cutting angles at the edge of the first outlet opening, as a result of which solids, such as foreign matter and fibers, can be cut very well and can then run off cut up with the liquid.

A further advantage of such a configuration of the first outlet opening is that cut foreign bodies do not become wedged or stuck in the first outlet opening of the perforated blade plate due to a steadily increasing cross section. As a result, a reliable outflow of solids from the chamber interior via the outlet opening can be ensured in an advantageous manner.

It is even more preferred that the size and/or the outlet opening cross section of the first outlet opening increases, in particular continuously, from the first end face to the second end face.

In this way, an improved cutting effect can be achieved in an advantageous manner due to the acute angle of the edge at the first outlet opening resulting from this configuration. In addition, good cutting performance can be maintained for a long period of time, so the life of the first die plate can be extended.

Still further, it is preferred that the plurality of further outlet openings extend from the first face of the first die plate to the second face of the first die plate.

Furthermore, it is preferred that the several further outlet openings in the area of the second end face are each larger than in the area of the first end face.

The number of further outlet openings preferably increases in size from the first end face to the second end face. The plurality of further outlet openings particularly preferably run conically from the first end face to the second end face.

Such a configuration of the several further outlet openings offers the advantage that the increasing cross section means that there are acute cutting angles at the edges of the several further outlet openings, as a result of which solids, such as foreign matter and fibers, can be cut very well and can then run off cut up with the liquid .

Furthermore, it is preferred that the size and/or the outlet opening cross section of the plurality of further outlet openings increases, in particular steadily, from the first end face to the second end face.

As described in relation to the first outlet opening, an improved cutting effect and a longer service life of the first perforated blade plate can thus be achieved in an advantageous manner.

According to a further preferred embodiment it is provided that the distribution chamber, the distribution chamber has a second wall, esp special has a second end wall with several connecting pieces.

The second wall is preferably arranged in the chamber interior on the opposite side of the chamber interior from the first wall.

One advantage of such a configuration is that liquid containing solids can be discharged on two sides of the distributor chamber, since the number of connection pieces can be increased. Such an embodiment is also advantageous for applications in which the liquid containing solids is to be distributed in two directions. This can be necessary, for example, with drag hose and/or trailing shoe linkages, especially when spreading liquid manure.

In a particularly preferred embodiment, the distributor device comprises a second hole cutter plate with a number of outlet openings which connect the interior of the chamber to the number of connection pieces of the second wall.

The second perforated blade plate can in particular be designed as a perforated blade disk. The second hole knife plate is preferably arranged on the second wall. The second hole knife plate is preferably designed like the first hole knife plate.

In a particularly preferred embodiment, the distributor device comprises a second cutting blade which has at least one cutting edge which rests against the second hole blade plate and can be moved relative to the second hole blade plate, the blade drive shaft being coupled to the second cutting blade so that when the blade drive shaft rotates by the drive shaft axis moves the second cutting blade relative to the second die plate.

The second cutting blade is preferably designed in accordance with the first cutting blade.

Furthermore, it is preferred if, in every position of the second cutting blade, there is a fluid connection between the connecting pieces of the second wall and the chamber interior via the outlet openings of the second perforated blade plate.

The second cutting blade is preferably designed in such a way that it does not completely cover one of the outlet openings in the second hole blade plate in any position. Thus, in an advantageous manner, as in the case of the first perforated blade plate, existing solids can be comminuted by means of the second cutting blade and clogging by solids can be avoided. At the same time, the relative movement between the second cutting blade and the second perforated blade plate cannot generate a strong negative pressure. The function of the second cutting blade can thus be fully utilized in an advantageous manner without negative pressure changes occurring as a result.

In a preferred embodiment, the distributor device comprises a tensioning device that is designed to bring about a contact pressure between the first cutting blade and the first hole blade plate.

The clamping device is preferably designed in such a way that a pressure force is formed between the cutting blade and the perforated blade plate; in particular, this pressure force can be adjustable by means of the clamping device.

With such a clamping device, an improved and constant cutting effect can be achieved between the first cutting blade and the first hole blade plate. The cutting effect can preferably be adjusted by adjusting the contact pressure, in particular as a function of the solids in the liquid and/or the sharpness of the edges of the first cutting blade and/or the first perforated blade plate.

Furthermore, it is preferred if the clamping device is designed to bring about a contact pressure between the several further cutting blades and the first perforated blade plate. The clamping device can also be designed to bring about a contact pressure between the second cutting blade and the second hole blade plate.

According to a further aspect, the object mentioned at the outset is achieved by a perforated blade plate for a distributor device, in particular a distributor device as described herein, comprising a first end face, which is designed to face a chamber interior of the distributor device, a second end face, which is designed in order to face away from the chamber interior of the distributor device, several outlet openings, which extend from the first end face to the second end face, wherein the outlet openings in the area of the second end face are each formed larger than in the area of the first end face, and/or wherein the size and /or the outlet opening cross-section of the outlet openings increases, in particular continuously, from the first end face to the second end face.

According to a further aspect, the object mentioned at the outset is achieved by using a perforated blade plate as described herein in a distributor device, preferably in a distributor device as described herein.

Using such a perforated knife plate in a distribution device offers the advantage that, particularly in combination with the cutting knives described herein, existing solids can be crushed and clogging by solids can be avoided and at the same time no strong negative pressure caused by a relative movement between the cutting knives and the perforated knife plate is produced. Thus, by using such a perforated knife plate, a desired comminution of the solids can be achieved in an advantageous manner without undesired pressure changes, in particular in the form of temporary negative pressure.

For the advantages, design variants and design details of the various aspects of the solutions described here and their respective possible developments, reference is also made to the description of the corresponding features, details and advantages of the respective other aspects and their developments.

1 shows a top view of a hole cutter plate 100 with cutting knives 51, 52, 53 lying against it. In the exemplary embodiment shown, three cutting knives are provided, but a different number of cutting knives can also be used. The cutting blades 51, 52, 53 are equidistant from each other. The cutting knives 51, 52, 53 are driven by a drive motor, so that the cutting knives 51, 52, 53 are moved relative to the punch plate 100. The cutting knives 51, 52, 53 move on a movement path K, which is circular. The cutting knife 51 thus moves relative to the first outlet opening 101 and then in the specified order along the further outlet openings 102. The movement of the cutting knife 51 is then repeated and the first cutting knife is again moved in the same order along the outlet openings. The cutting blades 52 and 53 move on the same path of movement K. The direction of rotation in which the cutting blades move on the path of movement can preferably be reversible. The outlet openings 101, 102 are designed in the form of oblong holes which, however, preferably have a non-constant cross-section along the thickness direction of the perforated blade plate. The outlet openings preferably extend conically into the plane of the figure with an increasing area towards the other end face of the hole cutter plate 100. This creates an acute-angled cutting edge at the outlet openings on the end face of the hole cutter plate 100 shown here, on which the cutting knives 51, 52, 53 on the hole cutter plate 100.

The cutting blade 51 has a width B1 and a length L, the length extending radially outward and the width extending in the direction of the movement path K. The width B1 is smaller than the width B2 (the width B2 is shown by way of example at one of the other outlet openings 102) of the outlet openings 101, 102. In particular, the width B1 is smaller than the width B2 of each individual outlet opening 101, 102. The cutting knives 52 , 53 have the same width as the width B1. This configuration of the cutting blades ensures that the outlet openings are not completely covered in any position of the cutting blades. There is thus a fluid connection between each of the connecting pieces via the outlet openings to the interior of the chamber in every position of the cutting blades. As a result, there is no negative pressure or only a very small negative pressure in the outlet openings or in the connecting pieces arranged thereon and the hoses connected to them. This enables the liquid to be discharged precisely and evenly from the distribution chamber without the need for air to be sucked into the distribution chamber.

2 . shows a longitudinal section through a perforated blade plate 100 with cutting blades 51, 52 lying against it 2 The view shown is a sectional view of FIG 1 Hole cutter plate 100 shown, the sectional view being a view in the direction of FIG 1 indicated mark AA. Thus, in addition to the hole cutter plate 100, the cutting blade 51 is also shown in a sectional view. This in 1 The cutting knife 53 shown is not visible in this view.

The hole cutter plate 100 has a first end face 151 which faces the interior of the chamber. Furthermore, the hole cutter plate 100 has a second end face 152 which faces away from the interior of the chamber. The top view in 1 shows the first face 151 of the die plate. The thickness of the perforated blade plate 100 results from the distance between the first face 151 and the second face 152. The thickness of the perforated blade plate 100 is constant in the exemplary embodiment shown. The outlet opening 101 of the perforated knife plate is conical, the outlet opening 101 outlet opening being larger in the area of the second end face 152 than in the area of the first end face 151. The area and the outlet opening cross section of the first outlet opening 101 increase from the first end face 151 to the second end face 152, steadily increasing. This creates an acute-angled cutting edge at the outlet opening 101 on the first end face 151 of the perforated blade plate 100, on which the cutting blades 51, 52 rest on the perforated blade plate 100.

The second end face 152 of the perforated knife plate 100 is arranged on the inside 250 of the end wall 5 so that the second end face 152 of the perforated knife plate 100 bears against the inside 250 of the end wall 5 . The hole cutter plate 100 is fixed to this end wall 5 so that the hole cutter plate 100 cannot be moved. However, the die plate can be detachably connected to the end wall 5 in order to enable the die plate 100 to be replaced.

A first connecting piece 30 and several further connecting pieces 31 are arranged on the end wall 5 . The first connecting piece 30 is in fluid communication with the chamber interior via the outlet opening 101 . The connecting pieces 30, 31 are in fluid connection with the chamber interior via the outlet openings in the perforated blade plate 100. Hoses can be attached to the connecting pieces 30, 31 in order to dispense liquid via these hoses. The connecting pieces 30, 31 are tubular. As a result, liquid containing solids can be optimally drained through the outlet opening 101 through the connecting piece 30 .

Numeral 1000 designates a portion of the drive shaft axis. A blade drive shaft (not shown in this illustration) is rotatably mounted around this drive shaft axis 1000 and coupled to the cutting blades 51, 52, so that when the blade drive shaft rotates about the drive shaft axis 1000, the cutting blades move in a circular manner relative to the perforated blade plate 1000 and rotate about the drive shaft axis along the Hole cutter plate 100 are moved.

3 shows an isometric view of a distribution device 1. The distribution device 1 is designed for distributing liquids containing solids, in particular liquid manure. The distributor device 1 comprises a distributor chamber 2. The distributor chamber 2 has an inlet opening 10 through which liquid containing solids can be introduced into the distributor chamber 2 into the interior of the chamber. A hose can be connected to the inlet opening 10, via which the liquid containing solids is introduced into the distribution chamber. The distribution chamber 2 also has a first end wall 5 and a second end wall 7 (hidden in this view) on the other side of the distribution chamber.

A first connecting piece 30 is arranged on the first end wall 5 . Furthermore, a number of further connection pieces 31 are arranged on the first end wall. Liquid containing solids can be discharged evenly and precisely from the chamber interior of the distribution chamber 2 via the connecting pieces 30, 31. For this purpose, hoses can be connected to the connecting pieces 30, 31, via which the liquid containing solids, in particular liquid manure, can be discharged. Such hoses connected to the connecting pieces 30, 31 can, for example, be hoses of a trailing hose linkage or a trailing shoe linkage.

A second connecting piece 40 and several further connecting pieces 41 are arranged on the second end wall 7 . Liquid containing solids can be discharged evenly and precisely from the chamber interior of the distribution chamber 2 via the connection pieces 40, 41--like via the connection pieces 30, 31. For this purpose, hoses can be connected to the connecting pieces 40, 41, via which the liquid containing solids, in particular liquid manure, can be discharged. Such hoses connected to the connecting pieces 40, 41 can, for example, be hoses of a trailing hose linkage or a trailing shoe linkage.

A drive motor 20 is also arranged on the side of the second end wall 7, which is coupled to the cutting knives (not visible in this view) arranged in the distribution chamber 2, so that the cutting knives can be driven by the drive motor to cut solids and fibers in the distribution chamber to be crushed by shearing.
