Description

Technical Field

[0001] This invention relates to the field of poultry farming equipment technology, specifically to a timed spraying and manure recycling device for duck egg-laying cages. Background Technology

[0002] In the large-scale breeding of egg-laying ducks, the cleanliness of the cages directly affects the health and egg production rate of the ducks. Currently, most egg-laying duck cages are cleaned manually on a regular basis, which is not only labor-intensive and inefficient, but also prone to the accumulation of manure and water due to untimely cleaning, which breeds bacteria, produces odors, and affects the growth environment of the ducks. At the same time, the sprinkler devices in the existing cages are mostly continuous spraying or manual spraying, which results in serious waste of water resources and uneven spraying. Moreover, the manure and water after spraying are directly discharged without recycling, which causes water loss and is prone to environmental pollution. Existing methods for cleaning manure from duck cages primarily involve scraping with a scraper, which easily causes wear and tear on the cage's mesh belt. Furthermore, manure residue can easily remain in the gaps between the scraper and the mesh belt, resulting in incomplete cleaning. Inadequate partitioning of the duck rearing area also leads to ducks fighting over feed and trampling each other, negatively impacting egg production efficiency. Therefore, there is an urgent need for a timed spraying and manure collection device for duck cages. Summary of the Invention

[0017] Reference Figures 1 to 9A timed spraying and manure recycling device for a duck egg-laying cage includes a main cage structure, a timed spraying mechanism, and a manure recycling mechanism. The main cage structure is used for the zoned and standardized feeding of duck eggs. The timed spraying mechanism realizes automated timed swirling spraying to clean the cage. The manure recycling mechanism completes the solid-liquid separation, separate collection, and recycling of manure and solid feces. The three work together to complete the integrated operation of large-scale duck egg-laying farming.

[0018] In this embodiment, the sewage recycling mechanism includes symmetrically arranged vertical plates 1. A support frame 11 is fixedly connected to the bottom of the vertical plates 1, and the support frame 11 supports the entire equipment. A support plate 12 and a collection plate 114 for collecting sewage are horizontally fixed between the two vertical plates 1. The collection plate 114 is located above the support plate 12 and is U-shaped with its two sides vertically upward, forming a sewage storage space with an open top with the two vertical plates 1, which facilitates the centralized collection of sewage. One end of the support plate 12 is inclined to facilitate the centralized discharge of solid feces. Several small bearings 13 are fixedly fixed through the vertical plates 1. The small bearings 13 are sealed bearings and can be obtained by purchasing from the market or by private customization. The inner rings of the multiple small bearings 13 are respectively rotatably connected to a through rod 14, a transverse rod 15 and an active rod 18, so that the through rod 14, the transverse rod 15 and the active rod 18 can rotate around their own axes.

[0019] In this embodiment, a rolling cylinder 16 is rotatably sleeved on the through rod 14, a plurality of pressing cylinders 17 are sleeved on the outer side of the transverse rod 15, a rotating cylinder 19 is fixedly sleeved on the active rod 18, and a plurality of inclined strips 110 are fixed on the outer wall of the rotating cylinder 19. A plurality of conveyor belts 111 are arranged around the surfaces of the rolling cylinder 16 and the rotating cylinder 19, and the rolling cylinder 16 supports the conveyor belts 111. A servo motor 113 is fixed on the side of the vertical plate 1 by a support rod. The output shaft of the servo motor 113 is coaxially fixed with one of the active rods 18. The servo motor 113 drives the active rod 18 to rotate, thereby driving the rotating cylinder 19 and the conveyor belts 111 to drive. A discharge frame 112, which cooperates with the collection plate 114 for discharging sewage, is fixed through the vertical plate 1. The discharge frame 112 is connected to the water storage tank to realize the recycling of sewage.

[0020] In this embodiment, the main structure of the feeding cage includes corner plates 21 fixed to the top of the vertical plate 1. Square frames 2 are fixedly installed on the top of multiple corner plates 21. The square frames 2 are the main frame of the feeding cage. Hexagonal mesh 22 and double-curved mesh 23 are fixed on the surface of the square frames 2. The hexagonal mesh 22 is the standing surface of the ducks, which has good ventilation and can prevent the ducks from stepping on it and falling. The double-curved mesh 23 is grid-shaped and serves as the protective surface of the feeding cage. Feeding openings 24 are opened on the side of the double-curved mesh 23. Two mutually perpendicular dividing nets 25 are fixed on the surface of the double-curved mesh 23, which divide the interior of the square frame 2 into several independent feeding chambers. Movable nets 26 are movably connected to the side of the double-curved mesh 23 to facilitate the placement and grabbing of ducks. Feeding troughs 27 are fixedly installed on the side of multiple square frames 2. Each feeding chamber corresponds to a feeding opening 24, and multiple feeding openings 24 are located in the feeding troughs 27. The ducks can peck at the feed in the feeding troughs 27 through the feeding openings 24 to avoid fighting with each other.

[0021] In this embodiment, the timed spraying mechanism includes an elbow pipe 3, which is fixed to the vertical plate 1 by a fixing rod 31. The water inlet end of the elbow pipe 3 is connected to a centrifugal pump 32, which is connected to a water storage tank. A filter screen is placed in the water storage tank to filter the recovered manure water. The water outlet end of the elbow pipe 3 is connected to a diverter cylinder 33, which distributes the water flow evenly to each vertical cylinder 34. Several vertical cylinders 34 are connected to the bottom of the diverter cylinder 33. The vertical cylinders 34 are fixed to the top of the square frame 2, and each independent feeding chamber corresponds to at least one vertical cylinder 34 to ensure the uniformity of spraying. A delivery pipe 35 is fixed through the bottom of the vertical cylinder 34. The centrifugal pump 32 is electrically connected to a timer controller, which is a PLC programmable controller and can be obtained by purchasing from the market or by private customization.

[0022] In this embodiment, a limiting edge 36 is fixed to the surface of the conveying pipe 35, and a frustum cylinder 37 is threadedly fitted to the bottom of the conveying pipe 35. The limiting edge 36 axially limits the frustum cylinder 37 to prevent it from sliding down. A friction cylinder 38 is fixedly installed on the inner wall of the bottom of the frustum cylinder 37. Multiple inner spiral grooves 39 are opened on the inner wall of the friction cylinder 38. A foam block 310 is movably placed inside the vertical cylinder 34. Multiple limiting blocks 311 are embedded in the side of the foam block 310. The limiting blocks 311 slide with the inner wall of the vertical cylinder 34 to prevent the foam block 310 from rotating and shifting inside the vertical cylinder 34. A movable cylinder 312 is embedded in the bottom of the foam block 310, and the movable cylinder 312 slides in contact with the inner wall of the vertical cylinder 34. A rubber ring 313 is embedded in the bottom of the movable cylinder 312, and the rubber ring 313 abuts against the bottom of the inner wall of the vertical cylinder 34 to form a seal to prevent water leakage. A fixed sleeve 314 is fixedly embedded in the bottom of the movable cylinder 312, and a central rod 315 is fixedly embedded in the end of the fixed sleeve 314. A spiral blade 316 is fixed on the outer wall of the central rod 315. When the water flows over the spiral blade 316, it forms a swirling flow and generates a reaction force, which drives the central rod 315 to rotate.

[0023] In this embodiment, a rotating platform 317 is fixedly sleeved at the bottom of the movable cylinder 312, and a rotating cylinder 318 is fixedly sleeved on the surface of the rotating platform 317. Multiple outer spiral grooves 319 are formed on the surface of the rotating cylinder 318, and these outer spiral grooves 319 are adapted to the inner spiral grooves 39. Both the rotating cylinder 318 and the friction cylinder 38 are frustum-shaped. The buoyancy of the foam block 310 is greater than the impact force of the water flow on the spiral blade 316. When the water flow submerges the foam block 310, it drives the foam block 310 and its connected structure to move upwards, causing the rotating cylinder 318 to adhere to the inner wall of the friction cylinder 38. Driven by the spiral blades 316, the water flows through the outer swirling groove 319 and the inner swirling groove 39, and then sprays in a 360-degree swirling motion, achieving cleaning without dead angles. A frustum plate 320 is fixed to the bottom of the central rod 315. The outer wall of the frustum plate 320 is fixedly connected to the inner wall of the rotating platform 317, ensuring that the central rod 315 and the rotating platform 317 rotate synchronously. The rotating cylinder 318 is sleeved on the top of the friction cylinder 38. The elbow pipe 3, the diverter cylinder 33, the vertical cylinder 34, the conveying pipe 35, and the frustum cylinder 37 are connected in sequence to form a complete spray water channel.

[0024] In this embodiment, the conveyor belt 111 is made of synthetic rubber, which is wear-resistant, corrosion-resistant, and has good elasticity. The surfaces of multiple pressing cylinders 17 respectively abut against the surface of a portion of the conveyor belt 111. The pressing cylinders 17 press down the conveyor belt 111, so that the edges of two adjacent conveyor belts 111 produce drainage outlets, which facilitates the seepage of the sprayed sewage into the collection plate 114. The side edge of the inclined strip 110 is provided with a slope, and the inner edge of the conveyor belt 111 is kept inclined. The inclined strip 110 is located between the gaps on the inner sides of the two conveyor belts 111, and the inner side of the conveyor belt 111 matches the edge of the inclined strip 110. The inclined strip 110 separates the edges of the two conveyor belts 111, preventing them from rubbing against each other during transmission, ensuring stable transmission of the conveyor belt 111, and extending its service life.

[0025] In this embodiment, the fixed sleeve 314, the central rod 315, the conveying pipe 35, the spiral blade 316, and the frustum plate 320 are coaxially arranged to ensure stability during rotation. The inner wall of the friction cylinder 38 is parallel to the surface of the rotating cylinder 318 to ensure smooth rotation of the rotating cylinder 318. The top of the frustum cylinder 37 rests against the bottom of the limiting edge 36, and the rubber ring 313 rests against the bottom of the inner wall of the vertical cylinder 34 to form a sealing structure. The timer controller can freely set the spraying time, spraying interval, and spraying duration. In this embodiment, the preferred spraying time is 2 minutes each time and the spraying interval is 3 hours. The servo motor 113 is electrically connected to the timer controller to realize the linkage between the slow rotation of the conveyor belt 111 and the spraying action, so that there are no dead corners on the surface of the conveyor belt 111.

[0026] The working principle of this embodiment: Egg duck raising: Open the activity net 26 and put the egg ducks into the independent feeding chamber in the square frame 2. Feed the egg ducks through the feeding port 24. The dividing net 25 effectively prevents the egg ducks from fighting for feed and trampling each other, ensuring the growth environment of the egg ducks. Timed Spraying: When the set spraying time is reached, the timer controller automatically starts the centrifugal pump 32. The clean water (or filtered circulating sewage) in the storage tank is pressurized by the centrifugal pump 32 and transported to the elbow pipe 3, and then enters the distribution cylinder 33 to be evenly distributed to each vertical cylinder 34. The water flows along the vertical cylinder 34 and the conveying pipe 35 into the frustum cylinder 37. When the water flow submerges the foam block 310, the foam block 310 drives the movable cylinder 312, the central rod 315, the rotating cylinder 318 and other structures to move upward under the action of buoyancy, so that the rotating cylinder 318 is in contact with the inner wall of the friction cylinder 38. When the water flow washes the spiral blades 316 on the outer wall of the central rod 315, it generates a reaction. The force drives the central rod 315 to rotate, which in turn drives the rotating cylinder 318 to rotate at high speed along the inner wall of the friction cylinder 38. After the water flows through the outer swirling groove 319 of the rotating cylinder 318 and the inner swirling groove 39 of the friction cylinder 38, it is sprayed out from the bottom of the frustum cylinder 37 in a 360-degree swirling flow, evenly washing the hexagonal mesh 22, double-bend mesh 23, and partition mesh 25 of the feeding cage, achieving a thorough cleaning without dead corners. During the spraying process, the timer controller synchronously controls the servo motor 113 to rotate slowly. The servo motor 113 drives the active rod 18 and the rotating cylinder 19 to rotate, which in turn drives multiple conveyor belts 111 to slowly drive, ensuring that there are no dead corners on the surface of the conveyor belts 111. Wastewater recycling: After spraying, the wastewater and solid feces fall onto the conveyor belt 111. Multiple conveyor belts 111 move the wastewater and discharge it from the end of the support plate 12. The pressing cylinder 17 presses down the multiple conveyor belts 111 at intervals, so that a drain outlet is formed between two conveyor belts 111. The wastewater flows through the drain outlet and the gap between the conveyor belts 111 to the surface of the collection plate 114. The discharge frame 112 discharges the wastewater through the vertical plate 1, realizing the recycling of wastewater. Solid feces are transported to the support plate 12 with the rotation of the conveyor belt 111, realizing the centralized collection and treatment of solid feces. Recycling: The filtered sewage in the storage tank can be pumped again by centrifugal pump 32 to the timed spraying mechanism to realize the recycling of water resources and continuously provide water for the spraying action.

[0027] In use, first, remove the movable net 26 from the side of the double-curved net 23, then place the ducks into the breeding space, and then install the movable net 26 on the side of the double-curved net 23 to seal the side of the breeding space. The ducks stand on top of the hexagonal net 22. Then, put the feed into the feeding trough 27. The ducks eat by passing through the feeding port 24 through the double-curved net 23. After the centrifugal pump 32 is powered on, it delivers clean water from the storage tank into the distribution cylinder 33. The clean water fills the distribution cylinder 33 and enters the interiors of multiple vertical cylinders 34 and multiple conveying pipes 35. The clean water then passes through... When the bottoms of multiple frustum cylinders 37 are discharged and the foam block 310 is filled with clean water, buoyancy is generated. This buoyancy causes the foam block 310, limiting block 311, movable cylinder 312, rubber ring 313, fixing sleeve 314, center rod 315, spiral blade 316, rotating platform 317, rotating cylinder 318, outer spiral groove 319, frustum plate 320, and other structures to move upward. The rotating cylinder 318 moves upward and its surface abuts against the inner side of the friction cylinder 38. When the clean water washes the spiral blade 316, a reaction force is generated. This reaction force causes the foam block 310, limiting block 311, movable cylinder 312, and other structures to move upward. 12. The high-speed rotation of structures such as rubber ring 313, fixed sleeve 314, center rod 315, spiral blade 316, rotating table 317, rotating cylinder 318, outer swirl groove 319, and frustum plate 320 causes the outer swirl groove 319 to rotate around the axis of the center rod 315. Clean water is discharged through the outer swirl groove 319. The clean water rotates continuously as it is sprayed out, and the clean water is evenly sprayed out to wash the hexagonal mesh 22, double-bend mesh 23, separator mesh 25, and movable mesh 26. Feces and clean water fall onto the surface of multiple conveyor belts 111. The servo motor 113 is energized to drive the conveyor belts. A drive lever 18 rotates, causing the drive lever 18, rotating cylinder 19, and multiple inclined bars 110 to rotate synchronously. The rotation of the rotating cylinder 19 drives multiple conveyor belts 111 to move. The movement of the multiple conveyor belts 111 carries feces and sewage. Feces fall from the sides of the multiple conveyor belts 111 onto the support plate 12, completing the feces collection. Sewage flows through the drain outlets between the conveyor belts 111 into the sewage storage space formed by the collection plate 114, completing the separation of feces and sewage. The sewage is then discharged from the sewage storage space through the discharge frame 112, completing the sewage collection. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
