Description

Technical Field

[0001] This invention relates to a feeding system for raising and caring for poultry, the feeding system having a frame and a plurality of resting layers arranged at different heights of the frame for animals to rest, wherein a manure collection device having a substantially horizontally extending manure collection element is provided below at least one, particularly a plurality of, resting layers, and wherein each manure collection device is equipped with at least one manure extraction unit movable above the manure collection element, the manure extraction unit having at least one manure pusher plate for extracting manure from above the manure collection element. Furthermore, the invention also relates to a scraping element for the manure pusher plate of the manure extraction unit in a poultry feeding system. Background Technology

[0002] Multi-level rearing systems are known for raising poultry, especially laying hens. These systems are typically housed in barns or hall-like buildings. Rearing systems can be configured as open or closed systems. Closed systems are advantageous over open systems in that excrement secreted during poultry rearing, especially manure, is not uncontrollably distributed throughout the shed or building.

[0003] For animal welfare reasons, it has been proven advantageous that poultry in closed systems have significantly less contact with excrement, resulting in fewer diseases when raised in closed systems. In particular, for the controlled collection and removal of excrement, especially feces, accumulated during poultry rearing, a feces collection device with substantially horizontally extending feces collection elements is provided at the rearing system below at least one, especially several, or each dwelling layer.

[0004] Animal excrement held on the retention layer is collected on a feces collection element that preferably extends at least along the entire length of the retention layer. Feces on the upper side of the feces collection element are controlled to be drawn out over a predetermined time period by means of at least one feces ejection unit with a feces pusher that is movable above the feces collection element. The feces pusher has a scraping element that abuts against the upper side of the feces collection element, typically along its entire length. However, it has been shown that known feces ejection units only achieve a general cleaning effect at the feces collection element. Summary of the Invention

[0005] Therefore, the present invention improves the type of feeding system mentioned at the beginning, so that improved cleaning effect can be achieved in the feeding system, especially at the feces collection element of the feces collection device.

[0006] The purpose on which this invention is based is achieved by means of a feeding system for raising and feeding poultry. In particular, the manure pusher of the manure discharge unit has a scraping element having a scraping edge with a toothed profile that abuts against the upper side of the manure collection element.

[0007] Therefore, contrary to conventional understanding, the present invention proposes, instead of using a scraping element with continuous scraping edges, that the scraping edges at the scraping element now have a toothed profile or teeth. With the scraping element according to the invention, regarding the total length of the scraping element at the manure pusher, the scraping element still abuts the upper side of the manure collection element only with a predetermined proportion of its total length. Thus, a significantly smaller clamping surface is formed at the scraping element according to the invention, which, in combination with an equally large clamping force, more effectively cleans the upper side of the manure collection element. Therefore, during poultry farming, fewer cleaning steps are required at the manure collection device to remove the collected excrement below the retention layer to the desired degree.

[0008] According to a preferred improvement, the scraping element has a plate body with at least one fastening section and a pusher section with scraping edges facing the feces collection element. By means of the fastening section, which preferably extends along its entire length at the scraping element, the scraping element can be securely fastened, for example, to a rod-shaped retaining element of the feces pusher via, in particular, multiple fastening points. The pusher section with scraping edges at the scraping element constitutes a separate, however one-piece, part of the scraping element connected to the fastening section. The pusher section with scraping edges is preferably arranged along the longitudinal side of the fastening section facing the feces collection element, and the scraping edges have a toothed profile.

[0009] According to a preferred design of the feeding system, the fastening section is oriented substantially vertically during the operation of the scraping element, and the pusher section with toothed edges extends relative to the fastening section at an angle α ranging from 91° to 180°. The vertical orientation of the fastening section during operation achieves a favorable pushing effect on excrement detached at the manure collection element by means of the scraping element. The fastening section is preferably connected to a rod-shaped retaining element that houses the scraping element. For better cleaning at the manure collection element, the pusher section is oriented obliquely relative to the vertically extended fastening section during operation, by means of which excrement, especially feces, is detached at the manure collection element. In particular, the pusher section extends obliquely forward along the direction of movement of the manure pusher by means of its toothed scraping edges, which improves the detachment or lifting of excrement at the upper side of the manure collection element. In a preferred embodiment, the pusher section extends relative to the fastening section at an angle α of approximately 135°.

[0010] An improved feeding system proposes a toothed profile consisting of alternating protruding teeth and retracted tooth gaps, the protruding teeth contacting the feces collection element. Preferably, such a scraping element with a toothed profile has a plurality of teeth extending obliquely forward along the scraping edge in the direction of movement. In a preferred design, the scraping element has more than 20, preferably more than 30, such teeth at its scraping edge. Preferably, the protruding teeth at the push plate section are evenly distributed there. By means of the retracted tooth gaps between two adjacent teeth, a sufficiently deep recess is formed at the scraping edge, by means of which only partial contact between the scraping edge and the feces collection element is ensured. In one possible embodiment, the scraping element of the feeding system according to the invention has 32 teeth in contact with the feces collection element over a total length of approximately 1.3 m.

[0011] According to a preferred embodiment of the invention, the toothed profile at the scraping edge is asymmetrically configured about the longitudinal axis of the scraping element. This asymmetrical design, combined with the pivotable housing of the feces pusher (described below), allows for cleaning of different areas on the upper side of the feces collection element. Although the contact surface at the scraping edge is reduced due to the teeth, effective cleaning of almost the entire upper side of the feces collection element is still achieved. The longitudinal axis of the scraping element now falls precisely in the transition region from tooth to tooth gap and preferably on the tooth surface extending substantially perpendicular to the scraping edge. Alternatively, the toothed profile can also be symmetrically configured at the feces pusher, wherein a symmetrically implemented feces pusher requires asymmetrical housing by means of a pivoting unit for thorough cleaning of the entire surface of the feces collection element.

[0012] Preferably, the tooth gap at the toothed scraping edge, along the longitudinal direction of the scraping element, corresponds at least 0.3 times, preferably 0.9 times, and particularly preferably more than 1.2 times the size of the teeth protruding along the direction of the fecal collection element at the push plate section. Preferably, the tooth gap has a tooth gap width corresponding to at least 0.3 times, preferably 0.9 times, and preferably at least 1.2 times the tooth width. In the currently shown embodiment, the contact surface formed by the teeth protruding obliquely forward along the direction of movement of the scraping element has a ratio relative to the total length of the scraping element in the range of about 0.8 to <0.5, preferably about 0.45. Particularly when the ratio of tooth width to tooth gap width is <0.5, the entire surface of the fecal collection element is not directly cleaned during the movement of the scraping element during the cleaning process, which consists of two individual movements of the scraping element above the fecal collection element. However, tests have confirmed that the cleaning range of the teeth is wider than the width of the teeth because of the dragging effect that occurs when the feces collection element passes over it.

[0013] Preferably, the plate has a tilting section, which forms the upper side of the plate opposite to the scraping edge. By means of the tilting section located at the fastening section opposite to the pusher section, especially when the scraping element moves above the feces collection element, excrement that may accumulate or be pushed upwards in front of the scraping element is tilted out along the direction of movement a short distance in front of it as the feces pusher moves. This particularly prevents excrement from pressing against the upper edge of the scraping element and avoids possible contact between the excrement and the portion of the feces pusher downstream of the scraping element. In particular, the cleaning costs at the feces outlet unit, which requires regular cleaning, are advantageously reduced.

[0014] An improvement to the feeding system proposes that the unloading section extends at an angle of 91° to 180° relative to the fastening section and preferably extends only along a portion of the length of the fastening section in the longitudinal direction of the scraping element. By means of its inclined or parallel orientation relative to the fastening section within the 91° to 180° angular range, preferably at an angle of approximately 135°, the excrement drawn from the upper side of the manure collection element is optimally unloaded in the direction of movement as the unloading element moves above the manure collection element. This allows for more efficient cleaning of the manure collection element at the manure collection device of the feeding system. Furthermore, the rigidity of the plate body is improved by the angled push plate section and the unloading section extending from the fastening section. Preferably, similar to the push plate section provided on the opposite longitudinal side, the unloading section extends forward at an angle relative to the fastening section and in the direction of movement of the manure push plate.

[0015] Preferably, the forward-oriented dumping section extends only along a portion of the length of the fastening section. For example, in one embodiment, the end regions of the scraping element are configured not to have a dumping section extending above the fastening section. This allows for advantageous free passage in conjunction with the pivoting movement of the feces pusher at the feces extraction unit, as described below for the feces extraction unit.

[0016] According to a preferred embodiment, the fecal extraction unit has a drive unit for moving a fecal pusher plate along the longitudinal direction of the fecal collection element, wherein the scraping element is oriented at an angle relative to the longitudinal direction of the fecal collection element during operation. The drive unit is configured to move the fecal extraction unit above the fecal collection element of the fecal collection device in the opposite direction to the longitudinal direction of the fecal collection element. For example, the cleaning process is defined by the reciprocating motion of the fecal extraction device above the fecal collection element. Preferably, the fecal extraction unit moves longitudinally toward the fecal collection element from an initial position at the fecal collection element during the outward motion. Upon reaching a turning position, the fecal extraction unit moves back to its initial position by means of the fecal pusher plate during the return motion. During the cleaning process, the scraping element, in particular its longitudinal axis and thus the fecal pusher plate, has an inclined orientation relative to the longitudinal axis of the fecal collection element located below it. As the manure pusher moves to the upper side of the manure collection element, the detached excrement is led out through at least one longitudinal side of the manure collection element configured as a dumping edge, and the excrement is then collected in a manure ditch formed below the feeding system.

[0017] According to a preferred variant, the fecal extraction unit has a pivoting unit for changing the orientation of the fecal pusher relative to the fecal collection element based on the direction of movement of the fecal pusher above the fecal collection element. The pivoting unit directly interacts with the fecal pusher and adjusts its orientation about a pivot axis substantially perpendicular to the upper side of the fecal collection element. Preferably, the scraping element, and thus the fecal pusher, which is particularly movably housed in the retainer of the fecal extraction unit, has an orientation of approximately 20° relative to the longitudinal side of the fecal collection element. The pivoting unit is configured to space the front end of the scraping element, as viewed along the direction of movement via the fecal pusher, from the dumping edge for excrement at the fecal collection element. The rear end of the fecal pusher in the direction of movement terminates directly at or extends from the dumping edge of the fecal collection element by at least a portion therefrom. Preferably, the pivoting unit has a tension element guided via a steering roller, which is secured on both sides of the pivot axis by means of a corresponding section of the fecal pusher. By adjusting the tension element that works in conjunction with the feces pusher, the feces pusher is oriented above the feces collection element in a direction that is associated with the direction of movement of the feces pusher.

[0018] A preferred embodiment of the feeding system proposes that, by altering the orientation of the manure pusher combined with an asymmetrical design of toothed scraping edges—preferably with the toothed scraping edges asymmetrically arranged relative to a pivot axis defined by a pivoting unit—the manure pusher is configured to abut against different surface areas of the manure collection element during its movement in the opposite direction to the manure collection element. This design ensures that, although the toothed scraping edges, which can be asymmetrically or symmetrically implemented at the manure pusher, are constructed, almost the entire upper side of the manure collection element is still cleared of excrement accumulated during poultry rearing during the cleaning process and the associated reciprocating movement of the manure extraction unit above the manure collection element. By combining the toothed scraping edges at the manure pusher with an asymmetrical design of the scraping edges relative to the pivot axis, particularly the asymmetrical arrangement, and the pivoting of the manure pusher according to its direction of movement, more efficient cleaning of the manure collection element compared to known prior art is possible, making it possible to reduce the number of cleaning processes required per unit time.

[0019] According to a preferred embodiment of the feeding system, as the manure pusher moves in the opposite direction above the manure collection element, it changes orientation, adapting to the contact position between the upper side of the manure collection element and the manure pusher. Preferably, by means of a toothed design with scraping edges, when the orientation of the manure pusher is changed, preferably by means of a pivoting unit, the toothed scraping edges, especially with respect to the longitudinal side of the manure collection element, occupy different contact positions above the manure collection element during reciprocating motion, i.e., contact different surface areas of the manure collection element. This ensures that, despite the toothed embodiment of the manure pusher, manure is still removed from the entire surface of the manure collection element during the reciprocating motion of the manure pusher.

[0020] One possible design of the feeding system proposes a manure collection element having a belt body equipped with a tensioning device at at least one end of the belt body for tensioning the belt body in the longitudinal direction. Preferably, a belt body made of plastic material is used as the manure collection element. To prevent the manure collection element from sagging due to its mass acting in the direction of gravity, thereby ensuring a durable and undisturbed contact between the manure collection element and a manure extraction element that can move above the manure collection element, at least one end segment of the manure collection element works in conjunction with the tensioning device for tensioning the belt body in the longitudinal direction. The tensioning device includes at least one, and in particular several, spring elements acting in the longitudinal direction of the belt body. The spring elements generate a sufficiently high preload on the manure collection element to prevent sagging. Preferably, the manure collection element is additionally supported from below along a predetermined segment by a corresponding support structure formed at the frame.

[0021] According to a preferred design of the feeding system, multiple dwelling layers are arranged side-by-side at the same height, each with its own manure collection device, at the frame. Preferably, the feeding system has at least two dwelling layers for poultry arranged at the same height, wherein each of the dwelling layers arranged adjacent to each other at the same height has its own manure collection device along with a manure extraction unit located thereon. Preferably, particularly the longitudinally facing sides of the manure collection elements arranged side-by-side adjacent to each other form dumping edges for poultry excrement to be extracted from the manure collection elements by means of the manure extraction unit. In a possible design of the feeding system according to the invention, the manure extraction units are in operation at the side-by-side manure collection elements, i.e., during the cleaning process, they move relative to each other in opposite directions. Thus, the two manure extraction units have their initial positions at their opposite ends of the manure collection devices. Preferably, the manure collection devices extend at least one predetermined movement area for the manure extraction units on both sides of the dwelling layers respectively above them, which defines the initial position or turning position of the manure extraction units.

[0022] According to a second aspect, the present invention relates to a scraping element for a manure pusher plate in a manure discharge unit in a poultry feeding system.

[0023] The present invention also achieves the objective of the feeding system based on the invention in terms of the scraping element by having a toothed scraping edge that abuts against the upper side of the feces collection element. Thus, the scraping element constructed according to the invention directly abuts against the upper side of the feces collection element only by a predetermined proportion of its total length. The scraping element constructed according to the invention has a reduced clamping surface compared to known scraping elements, thereby achieving a significantly improved cleaning effect on the upper side of the feces collection element under the same clamping force. With this scraping element according to the invention, fewer cleaning processes are required at the feces collection device over a predetermined period of time, by means of which the feces collection element is particularly periodically removed from the feeding process.

[0024] In another aspect, the present invention relates to the application of a scraping element according to one of the preferred embodiments described above, the scraping element being used to draw out feces above a feces collection element in a poultry feeding system, wherein preferably, the scraping element, by means of its toothed scraping edges, abuts different surface areas of the feces collection element as it moves in opposite directions and draws the feces above the feces collection element. By using the scraping element constructed according to the invention, on the one hand, it is possible to simplify and thus efficiently clean the feces collection element disposed below the retention layer in a poultry feeding system. Furthermore, by using such a scraping element, compared with known solutions, cleaning of the feces collection device is achieved within a predetermined time period by means of a significantly reduced number of cleaning processes, thereby minimizing the cost of such cleaning.

The preferred embodiments or improvements described for the scraping element or application of the scraping element according to the invention are also preferred embodiments of the feeding system.

[0032] Figure 1A feeding system 10 for raising and nurturing poultry is shown, the feeding system having a frame 12 and a plurality of resting layers 14, 14' arranged at different heights of the frame 12 for the poultry to rest. A manure collection device 16 is provided below at least one, preferably a plurality of, resting layers 14, 14'. Each manure collection device 16 is configured as follows: Figure 4 It is known that it has at least one fecal collection element 18 that is substantially horizontally extended.

[0033] Each feces collection device 16 is equipped with at least one feces discharging unit 20 movable above the feces collection element 18, the feces discharging unit having at least one feces pusher 24 that discharging excrement from the upper side 22 of the feces collection element 18. Figure 4 The feces discharge unit 20 has a mechanism for directing the feces pusher 24 along the longitudinal direction R of the feces collection element 18. L Motion drive unit 26.

[0034] exist Figure 4 The feces pusher 24 drawn in the middle has a Figure 2 The scraping element 28 shown has a scraping edge 30 that abuts against the upper side 22 of the feces collection element 18. The scraping edge has a toothed profile. The toothed profile 32 is alternately formed by protruding teeth 34, 34' that directly contact the upper side 22 of the feces collection element 18 and retracted tooth gaps 36, 36'.

[0035] The scraping element 28 includes a plate body 38 having a fastening section 40 that is oriented or extended substantially vertically during operation of the scraping element 28. A pusher section 42 with scraping edges 30, facing the feces collection element 18, is also provided on the plate body 38. Teeth 34, 34' and tooth gaps 36, 36' are provided on the pusher section. The pusher section 42 extends at an angle α relative to the fastening section 40 at an angle ranging from 91° to 180°.

[0036] The pusher section 42, with its 32 teeth in the currently shown embodiment, moves along the direction R of the fecal pusher 24. B Extending forward at an angle. Thus externally... Figure 2 As can be seen, the toothed profile 32 is asymmetrically configured about the longitudinal axis A of the scraping element 28. The longitudinal axis A of the scraping element 28 is currently located on the transition region U between the tooth 34 and the tooth gap 36, especially on the tooth surface 44.

[0037] The tooth gaps 36 and 36' are located at the scraping edge 30 along the longitudinal direction R of the scraping element 28. A It has dimensions, especially the tooth gap width B. W Its dimensions, especially the tooth width B, are related to the prominent teeth 34 and 34'.Z Compared to the previous size, it is larger. Preferably, the tooth gap width B W It is the tooth width B Z It is 1.1 times larger, preferably at least 1.2 times larger.

[0038] like Figure 2 and Figure 3 As shown, the plate body 38 has a tilting section 46, which forms the upper side 48 of the plate body 38 opposite to the scraping edge 30. The tilting section 46 is similar to the push plate section 42, tilting relative to the fastening section 40 at the scraping element at an angle β in the range of 91° to 180°, preferably at an angle β of 135°.

[0039] The unloading section 46 is along the longitudinal direction R of the scraping element 28. A It extends only along a portion of the length of the fastening section 28. The unloading section 46 also obliquely scrapes away the movement direction R of the leading edge scraping element 28. B Orientation.

[0040] Such external influence Figure 2 As can be seen, the protruding teeth 34 and 34' at the push plate section 42 have a uniform tooth width B in their respective extension directions. Z Furthermore, the tooth gaps 36 and 36' formed between them respectively have a uniform tooth gap width B. W In one embodiment not shown in detail, the tooth width B Z and tooth gap width B W The teeth increase or decrease in size along the direction of tooth extension, so that the tooth surfaces 44 of teeth 34 and 34' extend wedge-shaped to each other.

[0041] exist Figure 4 The illustration exemplarily shows a feces collection device 16 to be disposed below the dwell layers 14, 14' of the feeding system 10, which has a feces outlet unit 20 disposed movably, particularly movable, above the feces collection element 18. The feces outlet unit 20 includes a feces pusher 24 having a scraping element 28 that interacts with the upper side 22 of the feces collection element 18.

[0042] The scraping element 28 is disposed at the rod-shaped retainer 50 by means of its fastening section 40, wherein the scraping element 28 is positioned relative to the longitudinal direction R of the feces collection element 18. L Oriented at an angle δ of approximately 20°. With the aid of the drive unit 26, the manure discharge unit moves along the upper side 22 of the manure collection element 18 via the manure pusher 24, and the poultry excrement collected on the manure collection element 18 moves downward from the manure collection element via the longitudinal side 52 that defines the dumping edge 52' of the manure collection element 18 and is transferred to the manure ditch that exists below the feeding system 10.

[0043] The feces extraction unit 20 also includes a pivoting unit 54, which is used to adjust the direction of movement R of the feces pusher 24 above the feces collection element 18 according to the direction of movement R. B The orientation of the feces pusher plate 24 relative to the feces collection element 18 is changed. The pivoting unit 54 includes a retainer 56, at which a pivot bearing 58 is provided for pivotally hinged to the feces pusher plate 24 at the retainer 56, the pivot bearing having a pivot axis Z perpendicular to the orientation of the feces collection element 18.

[0044] In the currently shown embodiment, the fecal collection element 18 is a belt 60, which runs along the longitudinal direction R. L It is supported at least from its underside at predetermined intervals. Furthermore, the belt 60 is connected at at least one end 60' to a section for longitudinal direction R. L The tensioning device 62 of the tensioning belt 60 works together. In one embodiment, the tensioning device 62 has a plurality of spring elements 64 acting on the ends 60' of the belt 60, said spring elements being configured as tension springs.

[0045] exist Figure 5 and Figure 6 It can be seen in Figure 4 An enlarged view of the feces collection device 16 shown in the figure, together with the feces extraction unit 20 that can extend beyond its movement, wherein multiple feces collection devices 16 are arranged side by side at the same height in the frame 12 of the feeding system 10. Figure 1 ).

[0046] Figure 5 and Figure 6 The diagram shows different moments during the cleaning process performed at 16 fecal collection devices. In particular, at... Figure 5 The fecal extraction unit 20 is shown in the image. Figure 4 The initial position P shown in the diagram moves during the outward journey by means of the feces pusher 24 at the orientation K1 to a turning position (not shown in detail) formed at the opposite end of the feces collection device 16, and... Figure 6 The fecal extraction unit 20 is shown above the fecal collection device 16. It moves from the turning position back to the corresponding initial position P at the fecal collection device 16 by means of the fecal push plate 24 in the orientation K2.

[0047] The feces extraction units 20, movably housed above the feces collection device 16, move in opposite directions relative to each other. Furthermore, by altering the orientation K1, K2 of each feces pusher above the collection element 18, combined with the asymmetrical design of the toothed scraping edges 30 at the scraping element 28—particularly the asymmetrical arrangement of the toothed scraping edges 30 relative to the pivot axis Z defined by the pivoting unit 54—each feces pusher 24 is configured to abut against different surface areas of the feces collection element 18 during its movement in the opposite direction. Therefore, the scraping element 28, by virtue of its teeth... Figure 5 The cleaning process shown in the diagram involves direct contact with the surface area of ​​the feces collection element during the outward motion, and this surface area differs from the surface area of ​​the feces collection element. Figure 6 The area shown is the surface region that directly contacts the teeth 34, 34' of the scraping element 28 during the return motion.

[0048] In an alternative embodiment, instead of the asymmetrically configured scraping edge 30 at the scraping element 28, a toothed scraping edge (not shown in detail) is also symmetrically implemented. The scraping element thus implemented, along with its symmetrically implemented toothed scraping edge, is also asymmetrically positioned at the retainer 56 relative to the pivot axis Z defined by the pivot bearing 58 of the pivot unit 54, in order to achieve thorough cleaning of the feces collection element 18 during reciprocating motion above the upper side 22 and to make contact with the upper side 22 at a staggered angle.

[0049] To enable the feces pusher plate 24 to pivot, the pivoting unit 54 has a tension element 68 guided via a steering roller 66, which is secured to both sides of the pivot bearing 58 by means of a section of the feces pusher plate 24. By adjusting the tension element 66, the feces pusher plate 24 causes the scraping element 28 located therein to move along a corresponding section above the feces collecting element 18. Figure 5 The orientation K1 shown in the figure and in Figure 6 The directional movement of K2 is shown in the figure. When the feces pusher 24 moves over the feces collection elements 18 arranged side by side, the excrement is led out through the longitudinal sides 52 facing each other into the gap 70 existing between the feces collection elements 18 and collected in the feces ditch (not shown in detail).
