Description

The invention relates to a device for homogenizing von Gülle according to the preamble of claim 1.

State of the art

In pig and cow barns with slatted floors, the manure is collected in collecting pits and / or channels under the floors. Over time, it usually forms in the first collected manure at the bottom of the collecting pit Sink layer, followed by a liquid layer, the in turn from a firmer layer Components is covered. This floating layer tends to Incrustations. To blockages due to crust formation for example in the channels under the slatted floor avoid and if necessary to prepare the manure for the Removed from the collecting pit, the manure must be homogenized become. Agitators are used for this, which are characterized by the longitudinal slots of the slatted floors in the one below Have the manure in place.

In the German utility model GM 93 00 514 is a device disclosed for crushing solid components in liquid manure, in the idle state to be inserted into the slots of  Slatted floors adjustable in a plate-like insert is. The device's agitator includes agitators that rotate about axes are pivotally limited. During a rotation of the agitator in the submerged liquid manure Agitator blades deflected and get into one Drive shaft axis angular position, in which it during the Rotary movement of the agitator act like a propeller. At In one embodiment, the agitator can be moved in the longitudinal direction Columns can be swiveled to cover a larger area of the To reach manure without moving the agitator.

The disadvantage, however, is that the pivot mechanism in Column longitudinal direction realized on a frame is and is difficult to use.

In addition, only a limited area can still be found the slurry is sufficiently homogenized at one immersion location be what in larger barns, especially with long ones Slurry channels, frequent repositioning of the device required makes.

The invention has for its object a device for Homogenize manure to provide with the one A comparatively larger area of liquid manure is used can be homogenized faster and easier.

This object is achieved by the features of claim 1 as well of independent independent claims 2 and 9 solved.

In the subclaims are advantageous and expedient Developments of the device according to the invention specified.  

The invention relates to a device for homogenizing from manure with a base part on which an engine and a Stirring device is attached, one with the motor connected drive shaft, a drive shaft guide and Stirring blade comprises, wherein the stirring device is formed is that they are in slit-shaped openings, especially one Slatted floors in stables for cattle and / or pigs can be introduced. An essential aspect of the invention lies now in that means for pivoting at least the Stirring device transverse to the longitudinal direction of the slit-shaped Openings are provided in the inserted state. By this measure can be done on both sides of a column Slatted floor, stirred with the device inserted, which results in a larger slurry volume in one underlying pit (e.g. in the longitudinal direction of a Collecting channel) can be homogenized. As a result, the Device according to the invention for the homogenization of a certain pit size, especially channel length, less often must be implemented.

Another essential aspect of the invention also lies in that the base part for pivoting in and out Stirring device in the slot-shaped openings and for a Swiveling the stirring device in the longitudinal direction of the slot-shaped openings exactly one during the stirring process Axle in the form of a wheel axle with a pair of wheels. This measure eliminates the need for a separate frame would otherwise be necessary to pivot the stirrer. Rather, the stirring device can be very easily on the Edges in the desired position tend to be one more Larger slurry volume in the pit below to reach. The pivoting movement is then particularly easy perform when the center of gravity of the engine and the Stirring device essentially in the area of the wheel axle lie. Because in this case the device has a good one Balancing their focus on. Through the  Procedure according to the invention can the stirring device not just swiveled, but guaranteed also an unproblematic, fast transport to Example of other locations.

To a favorable center of gravity distribution of the device receive, it is also advantageous if the wheel axle in Range of the axis of rotation of the drive shaft lies.

To achieve a simple and cheap construction it is also advantageous if the stirrer is pivotable together with the engine.

For advantageous handling of the invention It is also preferred if in the area of the device Wheel axis a fixing device for attaching the Device on z. B. a slatted floor is provided. As a result, it is not necessary that during the Homogenization process, an operator is always present got to.

In a further preferred embodiment, the Fixing device a lever arm, at the end of which screw clamp-type clamping device for engaging in the Slots of a slatted floor is arranged. This represents one effective attachment option with which the device according to the invention without z. B. the spars one Damage slatted floor can be fixed.

To ensure a high degree of variability in the attachment ensure, it is also advantageous if the lever arm along and across the slit-shaped openings of a Slatted floor is adjustable and / or lockable.

In a likewise preferred embodiment is in the range of the end of the motor opposite the stirring device  arranged at least one further wheel. By this measure prevents the motor from being transported when the device is transported can grind on the floor. In addition to the This also makes maneuvering easier for transporters the device in narrow spaces, for example narrow Corridors, relieved. Because the device can be on Raise the agitator and can only on the additional wheel be driven.

Another essential aspect of the invention is that the drive shaft guide at least one for Drive shaft preferably running parallel to the base part and / or engine-mounted support with at least one Bearing unit for the drive shaft at the end of the Agitator blades are attached, the support not is guided beyond the impeller and the drive shaft not encloses as well as with the drive shaft in one plane lies. This measure allows the resulting "sword-shaped" stirring device with "flying" Impellers, that is, impellers that are only at the end of the Drive shaft are attached and have no frame, run particularly flat. Because the "sword strength" will determined only by the diameter of the drive shaft, since it is generally sufficient, the parallel support is not wider than the drive shaft diameter. The has the advantage that the agitator even with very narrow Slit slits of a slatted floor that are not larger than 20 mm, can still be used. With conventional Column slots with z. B. 28 mm column width allows this creates additional space to the spars of the Slatted floor that the stirring device particularly far across inclined to the longitudinal direction of the column slots or spars can be. In addition, the "flying" impellers have the advantage that their dimensioning only by external Conditions (e.g. the slot length of the slatted floors) is limited and the flow behavior much better  is like a framed impeller, where the frame disturbs the flow.

In a particularly preferred embodiment of the invention is a bearing unit for the drive shaft at the end of the provided at least one support. It is convenient if this support extends into the area of the impeller holder is led. In this way, an adequate Realize drive shaft stabilization. For one further stability improvement and an additional Shielding the drive shaft it is also preferred to lead two supports to the storage unit. Possibly. can the Drive shaft can also be stored in a protective tube. This also shields the shaft and prevents this unwanted winding of straw and forage residues.

Furthermore, it is advantageous if the storage unit on End of the drive shaft to a receiving unit for the Agitator blades adjacent and the adjacent surfaces of Bearing unit and receiving unit in the direction of the axis of the Drive shaft looks at a polygonal outer contour, in particular a triangular or square outer contour exhibit. This will wind up straw or Forage residues, which may be the homogenization process or pulling the stirrer out of a can prevent slit-shaped opening, sheared.

To ensure easy and safe handling, is it is further advantageous if at least on the base part Handle is attached, the height and in particular is designed to be longitudinally adjustable.

In a particularly preferred embodiment of the invention the agitator blades are mounted on axles and from a flat Position swiveling to a limited extent and with means for quick Exchange the impeller. This measure leaves the stirring device changes to, for example  Adjust the viscosity of the slurry, which is an otherwise excessive Current consumption of the motor is avoided. A quick one Exchange may also be necessary if another Motor size should be used, the corresponding one The size of the impeller requires or if the impeller in the Insert have been damaged.

In a further preferred embodiment of the invention is the degree of swinging out of the agitator blades in the two possible directions of rotation of the drive shaft differ large. This measure can be used if appropriate Slurry consistency the direction of rotation can be changed at short notice, the stirring resistance of the wings and thus the current consumption to be able to influence the motor accordingly.

To achieve a great stirring effect, it is also advantageous if the outer contour of the impeller in unfolded state at least in sections in Has essentially the shape of a circle, the The center point is on the drive shaft axis. This is especially preferred when the impeller in unfolded a substantially vertical Take up position to the axis of rotation.

It is to improve the stirring effect when homogenizing of advantage if the are in the direction of flow Outer contour areas of the agitator blades when opened an upstand at least to one side surface of a Have wing. Another improvement occurs when the upstand on both side surfaces of an impeller is attached, with a T-shaped cross section of The impeller and upstand are created.

In one embodiment according to the invention with a It is the guide frame for the motor and the stirrer further preferred if the guide frame with a  Round pipe guide is equipped. Such Guide construction is inexpensive and has one comparatively high stability and great security Canting on. It is also easy to do Place the upper and lower limits. By a Lower limit can be prevented Agitator blades in work, for example on Hit the collecting pit floor (sewer floor) and damage it become. In addition, one can be previously considered cheap proven working depth on a new one, for example Set the place of use again immediately. By a limit upwards it can be avoided that the stirring device is pushed upwards by the thrust of the impeller. In addition, disturbing vibrations occur with a corresponding Noise pollution especially when the Stirring device between the upper and lower limit is set. This ultimately leads to one reduced material wear.

To with in an embodiment according to the invention Guide frame when pulling out the stirring device none Security risks (the device could fall over) it is also particularly advantageous if at a tilting of the arrangement of motor, stirrer and Guide frame transverse to the column bars or slots in the inserted state before or when pulling out the Stirring device from a slit slot is designed so that the arrangement automatically in a vertical position can be brought and locked in this.

For effective homogenization of a wide range of manure it is also preferred that means for tilting the Stirring device in the longitudinal direction of the slit-shaped Openings are provided. It is advantageous if the Means an elevation on one side and / or in the Grasp the middle in the lower area on the guide frame.  

This allows the complete device in the tilt the desired position, or if the elevation is attached in the middle, like a swing and move around. For example, the elevation includes a pair of rollers attached to the guide frame in the middle Position that can be lowered easily. In in the same way it is preferred if the means for tilting a tilting unit on the base part, on the motor and Stirring device are attached. The possibility of Tilting in the longitudinal direction of the slot-shaped openings is particularly advantageous when an inventive Stirring device is used in the z. B. the Mixing blades are so wide that they can barely get through Introduce slit slits in a slatted floor for pigs leave, but the drive shaft with parallel, prop-shaped drive shaft bearing much narrower than the impeller width or the slot length of the Is column slots. This leaves the imported one Stirring device enough space to get sufficient To be able to perform tilting movement in the slit slots.

The further development of Invention in that in the lower end of the Guide frame provided at least two transport rollers are. This allows the slurry mixer z. B. to one move to another location. Preferably at least two transport rollers arranged on a frame, which on Guide frame is attached.

To ensure the stability of the Increasing pig manure mixers will continue in the future suggested that at least two transport rollers, preferably four transport rollers, on a separate frame are arranged, which is releasably connected to the frame is. In this context, it is also preferred if the separate frame is designed such that it is in  Regarding the frame by one. Can tilt axis of rotation. This can increase the maneuverability of manure mixers and Transport frame can be increased. However, with this Embodiment also a safe stand during the To ensure operation, it is also from Advantage if there is a facility with which the tilt can be blocked.

To make the transport frame as flexible as possible and to realize as large a stand area as possible also suggested that the transport rollers on fold-out and / or swing-out and / or extendable Bearing arms are arranged, which in the unfolded, pivoted or extended position can be locked. In this context, it is advantageous if the Transport rollers and / or the bearing arms releasably with the Transport frame and / or frame are connected, for. B. via a plug-in system with a bolt and / or screw holder.

It is particularly advantageous if bearing arms for four Transport rollers are provided, which are in such a way Let the plane swivel parallel to the stand, that each two transport rollers together by means of the bearing arms can be pushed. This way it becomes possible Pig manure mixer to tilt, putting the to each other pushed transport rollers serve as the fulcrum.

To ensure effective handling of the invention Means are provided to ensure device over which the agitator blades in the longitudinal direction of the slit-shaped Opening aligned when inserting and / or swiveling can be.

In addition, it is to damage the impeller to prevent beneficial if the drive shaft on the end of the impeller protrudes beyond the impeller.  

It is also preferred to add one To provide transport device, preferably on the Wheel axle of the pig manure mixer can be latched in and even comprises a further pair of wheels and a bearing unit. Of the Pig manure mixer is clicked in Transport device tilted and in on the storage unit stored in the tilted state. In this position he can be then proceed simply and stably.

To create the possibility that in a simple way different supports and drive shafts with different Length or width - for different slit-shaped Openings or different pit depths - can be used can, it is further proposed that the at least a support attached to the base part and / or motor and the drive shaft connected to the motor configured in this way are that they are interchangeable.

In a further advantageous embodiment of the invention comprises the at least one on the base part and / or motor attached support a fluid connection, for preferably Water and at least one fluid outlet opening, the Fluid connection and the fluid outlet opening within the Stand together. By this measure is achieved that often in the upper area peat-like dried manure by adding a fluid, preferably Water, which has a stirrable consistency that matches the Homogenize the liquid manure underneath leaves. In this context, it is also preferred if the at least one fluid outlet opening in the area of the Bearing unit of the drive shaft is arranged. To this In this way, there is constant storage cooling, which is what Significant wear on the plain bearings used belittles.  

To easily a variety of It is possible to provide fluid outlet openings finally preferred if the at least one on the base part and / or engine attached support essentially from one Hollow profile is made.

Description of the embodiments

In Figs. 1 and 2, a first embodiment of a device according to the invention for homogenizing of manure that is used especially for slatted floors in stalls for cattle for use, and is hereinafter referred to as cattle slurry mixer. The cattle slurry mixer 1 comprises a base part 2 , to which a motor 3 and a stirring device 4 are attached. The stirring device 4 essentially comprises a drive shaft 5 connected to the motor (see FIG. 2), a drive shaft guide 6 and agitator blades 7 (shown in FIGS . 1 and 2 each in the opened state). The drive shaft guide 6 essentially has two supports 8 fastened to the motor and at the front end thereof a bearing unit 9 (cf. FIG. 5a). On the base part 2 there is also a wheel axle 10 with a pair of wheels 11 which is designed as a pivot axis for pivoting the stirring device 4 in the longitudinal direction of columns 12 of a slatted floor 13 . In order to obtain a favorable center of gravity of the device in relation to the wheels 11 , the wheel axle 10 lies in the area of the drive shaft 5 . To fix the wheels 11 with base part 2 and stirring device 4 on the slatted floor 13 for the homogenization process of the manure, a fixing device 14 is provided, which comprises a lever arm 15 , at the end of which a screw-type clamping device 16 is arranged for engagement in the columns 12 of the slatted floor 13 is. In order to be able to use the fixing device 14 as variably as possible, the lever arm 15 is divided by a joint 17 , so that an adjustment transverse and longitudinal to the columns 12 of the slatted floor 13 is made possible. If the lever arm is in the desired position, the joint 17 can be fixed by means 18 for locking.

The base part 2 is pivotable with respect to the lever arm 15 , a support 19 being arranged on the base part 2 and connecting the base part to the lever arm 15 via a hinged rod 20 and a further support 21 on the lever arm. The articulated rod 20 is guided in the upper region of the support 21 and can be fixed there in a simple manner. As a result of this measure, the stirring device 4 can be swiveled quickly and easily in the longitudinal direction of the gaps 12 and then locked.

According to the invention, however, the stirring device 4 together with the motor 3 can be deflected not only in the longitudinal direction of the columns, but above all also in the transverse direction of the columns (cf. in particular FIG. 1). For this purpose, the stirring device 4 with the motor 3 is tilted about the axis 22 and fixed by locking means 23 . In order to make this pivoting movement particularly easy in the fixed state of the cattle mixer 1 , the hubs of the wheels 11 on the wheel axle 10 can have a certain play, which allows a corresponding displacement of the base part 2 with stirring device 4 and motor 3 when tilting (see arrows in Fig. 1). A further pair of wheels 24 is arranged on the support 19 for easy transportation of the cattle manure mixer 1 . The cattle manure mixer 1 can thus be driven on the pair of wheels 11 and the pair of wheels 24 (see FIG. 3). A handle 25 for an operator 26 can also be provided for better handling. In particularly confined spaces, the operator 26 can only transport the mixer 1 on the rollers 24 for easy maneuvering (see FIG. 4).

In Fig. 5a to 5c an inventive Rührflügelpaar 27 in the front view (Fig. 5a), in the side view (Fig. 5b) and shown in plan view from below (Fig. 5c). The agitator blades are mounted on an axis 28 and can be swung out to a limited extent from the flat position. The axis 28 is fastened with an adjusting screw 53 (see FIGS. 5a and 5b) in a sleeve 54 welded to the receiving unit 31 . For this purpose, the sleeve 54 has a thread. A lock nut 55 can be provided to secure the set screw screwed into the thread. This construction has the enormous advantage that to change the impeller 27 only the set screw 53 with lock nut 55 has to be loosened in order to be able to slide out the axis 28 . Disassembly of the drive shaft or the like is not necessary.

The part 29 of the outer contour has the shape of a circle, the center of which lies on the axis of rotation 30 . In this way, a particularly effective stirring effect can be achieved. Another special feature will be explained with reference to FIGS. 5a and 5b. The bearing unit 9 at the end of the drive shaft 5 adjoins a receiving unit 31 for the agitator blades 27 , the surfaces of the bearing unit 9 and the receiving unit 31 lying against one another, viewed in the direction of the drive shaft axis 30 , have a rectangular outer contour. Such a measure shears off straw or feed components that tend to wind up.

A second embodiment of the invention is shown in FIGS. 6 and 7. This device for homogenizing liquid manure is mainly used for slatted floors 32 in stables for pigs. Compared to slatted floors for cattle, these are provided with significantly shorter slit slots, so that pivoting in of a stirring device 4 , as described in the case of the cattle slurry mixer 1 , is hardly possible. In addition, the slit slits 33 in stalls for pigs are even narrower than slatted floors for cattle. For this reason, the device 34 according to the invention, hereinafter referred to as pig slurry mixer, has a guide frame 35 for preferably lowering the motor 3 and stirring device 4 vertically. In the guide frame 35 to slide two guide tubes 36 which are connected by a base member 37 on which the motor 3 and the agitator 4 sit. At a suitable point, the stirring device 4 can be drained into the slurry via a crank device 38 through a slit slot 33 . In the case of a pig manure mixer 34 with a stirring device 4 according to the invention, the stirring blades can advantageously be designed as wide as the length of the slit slots in the slatted floor (for example, the length of the slit slots is 25 cm). This is possible because, unlike in the prior art, the impellers are not mounted in an additional frame, which of course comes at the expense of the impeller width. In order to prevent the thrust of the propeller from driving the stirring device up again when the motor starts, a stop 39 , which is easily adjustable, can be arranged on the guide frame 35 . If necessary, a further stop for limiting the penetration depth of the stirring device can also be provided below a guide tube 36 .

In order to be able to homogenize a particularly large area of the manure, the pig manure mixer 34 can also be tilted transversely to the longitudinal direction of the gaps 33 (see FIG. 7). The entire arrangement (motor, stirring device and guide frame 35 ) is tilted about the axis 40 , the desired tilt angle being determined by locking means 41 . A pair of wheels 42 is provided on a wheel axle 43 for easier transportation of the pig manure mixer 34 with the stirring device 4 raised.

To further improve the transport, an additional pair of support wheels 45 can be provided on a support 44 , as shown in FIG. 8a. The complete arrangement in the tilted state can thus be moved particularly easily (cf. FIG. 8).

In an alternative embodiment to FIG. 8a, an additional transport device 56 can be provided for improved transport of the pig manure mixer 34 (cf. FIGS. 8b and 8c). The additional transport device 56 comprises a fork-shaped latching unit 57 with a pair of wheels 58 attached to it on an axle 59 and a support 60 with a V-shaped bearing 61 attached to the upper end of the support.

For the transport of the pig slurry mixer 34, shown in Figs. Is shown from above in plan view, 8b and 8c, is the transport means 56 driven the fork-shaped click fitting assembly 57 to the wheel axle 43 of the columns mixer 34, and then the complete columns mixer 34 via the pair of wheels 42 tilted in the direction of the transport device and stored with a spar of the guide frame 35 in the V-shaped bearing 61 . Preferably, the receiving point of the latching unit 57 is locked by the tilting process, so that the wheel axis 43 of the pig manure mixer is fixed thereon. In this state (according to FIG. 8c), the pig manure mixer 34 can be moved in a simple manner together with the additional transport device 56 .

FIG. 8d shows a pig manure mixer 70 , which in the lower region of a guide frame 71 comprises an adjusting frame 72 with wheels 73 arranged on the side. In order to be able to transport this pig manure mixer 70 particularly easily and safely, a separate frame 74 with four transport rollers 75 to 78 is provided. The frame 74 are peg members 79, 80 provided, which fit into corresponding receptacles on the adjusting frame 72 so that the transport rack (not shown) 74 with additional locking means can be releasably connected to the assembly frame 72nd The transport rollers 75 to 78 are arranged on bearing arms 81 to 84 which are extendable in the frame 74 . The bearing arms 83 and 84 can also be pivoted in a range of 180 °. The position pivoted through 180 ° is shown in broken lines in FIG. 8d. In this way, the frame 74 can be pushed together with transport rollers 75 , 78 , provided the pig manure mixer is not being transported, in a small and compact manner, and if necessary also completely removed from the frame 72 . To transport the pig manure mixer, however, the bearing arms can be swiveled (bearing arms 83 and 84 ) and pulled out, so that the transport rollers 75 to 78 take up a particularly large footprint. This ensures a high level of stability against tipping when transporting the pig manure mixer 70 .

Another pig manure mixer 90 with a frame 91 and a transport frame 92 attached to it is shown in FIG. 8e. In this embodiment, the transport frame 92 can be tilted with respect to the setting frame 91 via the pivot axes 93 . The tilting can be blocked by a hook element 94 which is arranged on the transport frame 92 and which engages in the setting frame 91 and can be actuated via a lever mechanism 95 . Four transport rollers 99 to 101 are arranged on the transport frame 92 via bearing arms 96-98 (the fourth transport roller is not shown in FIG. 8e). Two transport rollers 97 , 98 can be folded out from a folded-up state and locked with a hook 102 . In contrast, the two rollers 99 on the arms 96 are pivoted outwards and z. B. fixed by bolt 103 . The folded-out or swung-out state of the transport rollers 99 to 101 is preferably the transport state.

Two possible transport positions are shown in FIGS. 8f and 8g. The hook element 95 is hooked onto the axis 104 of wheels 105 on the setting frame 91 , so that the pig manure mixer 90 is moved perpendicular to the transport frame 92 (see FIG. 8f). In the other case ( FIG. 8g), the complete pig manure mixer 90 is tilted during transport with the hook element 95 unhooked, which can simplify the handling of the entire arrangement, ie the maneuverability during transport.

The bearing arms 96 to 98 can, as shown in FIG. 8e by way of example on the bearing arm 96 , be removed from the transport frame 92 in a simple manner on account of a plug connection. To secure the bearing arms 96 to 98 , the plug connection has locking means 106 (e.g. screws).

FIG. 9 shows a drive shaft 5 with an agitator blade 46 according to the invention on axes 47 which can be exchanged in a particularly simple manner. For this purpose, only the screw means 48 have to be loosened and the impellers exchanged for other desired impellers. Other impeller shapes are indicated in Fig. 9 by the dashed lines. They come into consideration if, for. B. changes the slurry consistency and yet the load on the engine should be in a constant range. In order to have a further parameter available with regard to the motor load or the stirring action, the exchangeable stirring blades 46 can be designed such that they swing out to different degrees depending on the direction of rotation (cf. FIGS. 10a and 10b).

The drive shaft 5 in FIGS . 9 and 10a and 10b projects beyond the impellers in the folded state. In this way it is prevented that the impellers are damaged if the stirring device should sit on the bottom of a collecting pit (slurry channel).

In Fig. 11 a sleeve 49 is partially shown in section. This serves to bring the stirring blades of a cattle manure mixer 1 before swiveling out or a pig manure mixer 34 before being pulled out of the slit slots 12 , 33 of a slatted floor 13 , 32 into a position parallel to the columns 12 , 33 . The sleeve 49 is arranged, for example, in the area below the motor 3 of the cattle manure mixer 1 or the pig manure mixer 34 on the drive shaft 5 . The aim of the adjustment is to align a pair of bores 50 that fit a pin 52 perpendicular to the supports 8 , which corresponds to a parallel alignment of the impellers to the column slots 12 , 33 without an operator having to have eye contact to the sleeve 49 , which is also the case is difficult because the sleeve is under the engine. For this purpose, the sleeve 49 has, in addition to the pair of holes 50, a further opposite pair of holes 51 .

If the appropriate bore 50 is not accessible to the pin 52 due to the drive shaft guide during the turning process, the bore 51 can be inserted with the pin 52 in any case. The holes 51 are too large for the pin 52 , so that it wobbles. The operator thus knows that it is located in a bore 52 , which is only used to continue turning until a bore 51 is freely accessible and can be aligned vertically with the appropriately inserted pin 52 .

A further variant of bringing the stirring blades, for example of a pig manure mixer, into a parallel position before being pulled out of slit slots in a slatted floor is shown in FIGS . 12a to 12c. The pig manure mixer 110 shown as an example has a box-shaped unit 111 with a cover flap 112 directly below a motor 113 for driving a stirring device. The box unit 111 is penetrated by the drive shaft 114 driven by the motor 113 . A positioning disc 115 mounted on the drive shaft 114 rotates in the box unit 111 (see FIG. 12c). Two notches 116 are provided, for example at diametrically opposite locations of the positioning disk 115 to the positioning 115th The positioning disk 115 partially protrudes from the box unit 111 via a slot 117 . This protruding positioning disc portion is covered by the correspondingly curved cover flap 112 when the pig manure mixer is in operation.

In order to align the stirring blades of the pig manure mixer in parallel before removing them from a slit slot, the flap 112 is opened and the notch 116 is brought into the slot 117 in the middle. This position then corresponds to the parallel orientation of the agitator blades. Of course, a variety of other marking options can be used on the positioning disc.

In order to prevent that the cover flap 112 is not simply opened during operation and, moreover, the cover flap is only opened deliberately, two safety devices are provided which have to be actuated for the flap opening.

These safety devices are shown schematically in FIG. 12b. On the one hand, there is a spring-loaded lever 122 which engages in a gap between the cover flap 112 and the box unit 111 and thus blocks the opening of the cover flap 112 , provided that it has not been swung out of the gap. Furthermore, a pin element 119 which is mounted in an eyelet 118 is provided and is guided through a further eyelet 120 arranged on the cover flap. The pin element 119 has a barb-like spread 121 , which normally strikes the eyelet 120 when trying to open the cover flap. However, the pin element 119 is resilient and the spreading 121 is dimensioned such that it basically fits through the eyelet 120 , so that by slightly bending in the elastic region of the pin element 119 the spreading 121 can be guided through the eyelet 120 and the cover flap 112 thus open leaves.
