Description

Technical Field

[0001] This invention relates to the field of manure collection technology, and in particular to a device and method for collecting manure from pig farms in buildings. Background Technology

[0002] With the acceleration of urbanization, more and more pig farms are adopting building-style farming models to save land resources and improve efficiency. However, this farming model has also brought new problems, especially the collection and treatment of manure and sewage. Building-style pig manure collection devices are an important part of modern farming technology. They are designed to efficiently and environmentally treat the manure and sewage generated during pig farming. Building-style pig manure collection devices are usually installed in each pig farming floor. Through a series of mechanical and pipeline equipment, the manure and sewage produced by pigs are collected and treated in a centralized manner.

[0003] Currently, when using building-based pig farming, the process of cleaning and collecting manure from each floor is time-consuming, labor-intensive, and inefficient due to the large number of floors. Existing manure cleaning and collection devices in buildings all use scrapers to remove manure from the ground. However, due to the large number of pigs, the scraper is inefficient. Furthermore, when using automated multi-layer simultaneous scraping, the high solid content in the manure can easily cause blockages in the drainage pipes. Moreover, after cleaning and collecting the manure, it tends to solidify and emit odors if left in the collection tank for a long time, which can affect the health of the pigs. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of difficulty in collecting manure and sewage in buildings and the easy blockage of sewer pipes in the prior art, and to propose a device and method for collecting manure and sewage from pig farming in buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A building pig manure collection device includes a drain outlet on one side of the floor slab, a pad rotatably mounted on the floor slab, a lifting part on the inner floor that drives the pad to swing up and down, and a water collection tank slidably mounted on the floor slab. A drain pipe is fixedly connected to the water collection tank. The floor slab is equipped with a swinging part. When the lifting part drives the pad to swing up and down, the swinging part drives the water collection tank to reciprocate.

[0007] Preferably, the lifting unit includes a lifting plate slidably installed on the inner floor, a plurality of top plates are fixedly connected to the lifting plate, a top rod is fixedly connected to the top plate, the top rod is slidably installed inside the floor slab, a support plate is fixedly connected to the top rod, and the support plate is fitted onto a pad. A drive motor is fixedly connected to the inner floor, and a threaded rod is fixedly connected to the output shaft of the drive motor. The lifting plate is engaged with the threaded rod.

[0008] To prevent the drain pipe from getting clogged, preferably, the swinging part includes an arc-shaped block, and a placement groove is provided on the top plate. The arc-shaped block is fixedly connected inside the placement groove, and the arc-shaped block cooperates with the protrusion.

[0009] To facilitate the discharge of sewage, a slider is fixedly connected to the water collection tank, a groove is provided on the floor slab, the slider is slidably installed in the groove, a support spring is fixedly connected to the slider, and the free end of the support spring is fixedly connected to the groove.

[0010] To further flush the fecal matter on the mat, several flushing pipes are rotatably installed inside the inner floor, and high-pressure nozzles are fixedly connected to the flushing pipes.

[0011] To further improve flushing efficiency, a mounting bracket is fixedly connected to the flushing pipe, a mounting rod is rotatably mounted on the mounting bracket, and a rotating plate is fixedly connected to the mounting rod. A connecting plate is fixedly connected to the top plate, and a limiting groove is opened on the inner floor. The top plate and the connecting plate are slidably installed inside the limiting groove, and a connector is fixedly connected to both the top plate and the connecting plate. The rotating plate is rotatably installed inside the connector.

[0012] To further prevent fecal matter from solidifying and clogging, a sludge storage tank is fixedly connected to the outer floor, the outlet end of the drain pipe extends into the sludge storage tank, the threaded rod is rotatably installed in the sludge storage tank, and a stirring rod is fixedly connected to the threaded rod.

[0013] To further prevent odors from being generated in the sludge storage tank, an adjustment groove is provided on the lifting plate. A moving rod is slidably installed in the adjustment groove, and a brush head is fixedly connected to the moving rod. The brush head is fitted against the inner wall of the sludge storage tank. A return spring is fixedly connected to the moving rod, and the free end of the return spring is fixedly connected to the adjustment groove. A toggle rod is fixedly connected to the moving rod, and the toggle rod cooperates with the stirring rod.

[0014] To prevent pipe blockage during simultaneous sewage discharge, a rotating rod is fixedly connected to one end of the pad, which is rotatably mounted on the floor slab. The pad has drainage holes, and the floor slabs and pads on each floor are arranged in opposite directions and alternately.

[0015] A method for collecting manure from pig farms in buildings also includes the following steps:

[0016] S1. Start the drive motor to lower the lifting plate. The pad plate will tilt due to the loss of support from the support plate. At the same time, turn on the high-pressure nozzle to spray water to flush the feces and dirt on the pad plate.

[0017] S2. When the lifting plate descends, the arc-shaped block and the convex block work together to squeeze the drain pipe, causing the drain pipe and the water collection tank to sway left and right to facilitate material discharge and prevent blockage. At the same time, the rotating plate pulls the flushing pipe to rotate, so that the high-pressure nozzle can be adjusted in angle according to the tilt of the pad.

[0018] S3. When the drive motor drives the threaded rod to rotate, the stirring rod on the threaded rod stirs the fecal sludge in the sludge storage tank to prevent solidification and blockage.

[0019] S4. As the lifting plate descends, the brush head fixedly connected to it scrubs and cleans the inner wall of the sludge storage tank to prevent odors from being generated. At the same time, the agitator on the brush head moves left and right in conjunction with the rotation of the stirring rod, improving cleaning efficiency.

[0020] Compared with the prior art, the present invention provides a device and method for collecting pig manure in buildings, which has the following beneficial effects:

[0021] 1. This building's pig manure collection device, through the cooperation of a lifting unit and a pad, achieves automatic collection and discharge of manure within the building, effectively reducing manual intervention and improving cleaning efficiency. When the drive motor starts, the lifting plate gradually descends under the drive of the threaded rod. During this process, the support plate detaches from the pad, causing the pad to tilt due to loss of support. This allows the manure on the pad to flow naturally into the collection tank. At the same time, this tilting design also optimizes the flow path of the manure, avoiding the problems of low cleaning efficiency and pipe blockage caused by the scraper directly scraping away the manure affected by the pigs.

[0022] 2. The pig manure collection device in this building utilizes a design with protrusions and arc-shaped blocks. During the descent of the lifting plate, the arc-shaped blocks compress the protrusions, causing the drain pipe and collection tank to sway from side to side. This dynamic movement not only facilitates the smooth discharge of manure but also effectively prevents the risk of blockage in the drain pipes caused by prolonged stagnation, ensuring the smooth operation of the entire system.

[0023] 3. The building's pig manure collection device uses a stirring rod fixedly connected to a threaded rod. When the drive motor rotates the threaded rod, the stirring rod rotates accordingly, continuously stirring the manure in the storage tank, effectively preventing the coagulation and blockage of the manure.

[0024] 4. The building's pig manure collection device uses a brush head and a lever on a lifting plate. When the lifting plate descends, the brush head scrubs and cleans the inner wall of the sludge storage tank, preventing odor generation. At the same time, the lever and stirring rod work together to allow the brush head to move left and right while scrubbing up and down, further improving cleaning efficiency.

[0025] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention makes the process of cleaning fecal waste faster and more efficient by setting up a lifting unit, while effectively avoiding the problem of sewer pipe blockage during sewage discharge.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Example:

[0040] Reference Figures 1-8A pig manure collection device for buildings includes: several floor slabs 5 fixedly connected to an inner floor 11, with at least 4 floors 5, generally 4-8 floors, forming a multi-layer structure, each floor can be used for breeding. Each floor slab 5 has a drain outlet 53 on one side for discharging wastewater and manure generated during cleaning or naturally occurring. The inner floor 11 is equipped with a lifting mechanism that drives a pad 51 to swing up and down. The pad 51 supports the pigs and facilitates cleaning. The lifting mechanism on the floor slab 5 supports the pad 51 and adjusts its height for easy collection and discharge of manure. A water collection tank 55 is slidably installed on the floor slab 5, with its bottom inner wall inclined towards the outlet, and can swing left and right to facilitate manure discharge. A drain pipe 7 is fixedly connected to the water collection tank 55 to guide the collected manure to a storage tank 3. The upper part is equipped with a swinging part. When the lifting part drives the pad 51 to swing up and down, the swinging part drives the water collection tank 55 to reciprocate. When the lifting part moves up and down, the drain pipe 7 vibrates through the swinging part to prevent blockage inside the drain pipe 7. One end of the pad 51 is fixedly connected to a rotating rod 52, which is rotatably installed on the floor slab 5. This connection method allows the pad 51 to rotate around the rotating rod 52, thereby achieving angle adjustment. The pad 51 is provided with drainage holes. The inclination directions of each floor slab 5 and the pad 51 are opposite and alternately arranged. The purpose of these drainage holes is to drain water so that liquid can be smoothly discharged from the surface of the pad 51 to avoid water accumulation. By setting the inclination directions oppositely, the water flow can be guided more effectively to avoid water accumulation in the same direction, and at the same time, to avoid blockage of the drain pipe when draining through a single drain pipe 7.

[0041] The outer floor 1 serves as the main frame of the overall structure, providing space for the installation of the inner floor 11 and other components. The inner floor 11 is fixedly installed inside the outer floor 1 and is used for raising pigs.

[0042] Pigs move around on the pads 51 on the floor slab 5. The manure they produce falls into the space below the floor slab 5 through the gaps in the pads 51 or through periodic cleaning. It is then directed into the collection tank 55 through a specially designed drain 53. The collection tank 55 not only serves as a temporary container for storing manure, but its sloping bottom design also promotes the natural flow of waste to the outlet, further improving sewage discharge efficiency. In addition, the left and right swaying function of the collection tank 55 is achieved by the lifting mechanism, which effectively prevents waste from accumulating or solidifying inside the tank, ensuring unobstructed sewage discharge.

[0043] During the collection of fecal waste, the inclination directions of each floor slab 5 and its base plate 51 are carefully designed to be opposite and intersecting. This unique layout not only optimizes space utilization but also promotes the natural flow of waste between different floors, preventing it from entering a single drain pipe 7 at the same time during cleaning and causing blockage. This reduces the need for manual intervention. At the same time, this design also improves the overall cleaning efficiency, allowing fecal waste to be introduced into the collection tank 55 more quickly and discharged smoothly into the sludge storage tank 3 through the drain pipe 7.

[0044] Reference Figures 3-4 The lifting unit includes a lifting plate 4 slidably installed on the inner floor 11. Several top plates 41 are fixedly connected to the lifting plate 4, and the number of top plates 41 corresponds to the number of floor slabs 5. A top rod 45 is fixedly connected to the top plate 41. The top rod 45 is slidably installed inside the floor slab 5. A support plate 46 is fixedly connected to the top rod 45. The support plate 46 is fitted onto the pad 51. When the lifting plate 4 moves up and down, the top rod 45 will also slide inside the floor slab 5, thereby changing the tilt angle of the pad 51 inside the floor slab 5. A drive motor 32 is fixedly connected to the inner floor 11. A threaded rod 33 is fixedly connected to the output shaft of the drive motor 32. The rotation of the drive motor 32 will drive the threaded rod 33 to rotate together. The lifting plate 4 is meshed with the threaded rod 33. When the threaded rod 33 rotates, due to the meshing action of the thread, the lifting plate 4 will move up and down along the axial direction of the threaded rod 33.

[0045] When it is necessary to adjust the floor height or perform other lifting operations, the drive motor 32 is started. The drive motor 32 drives the threaded rod 33 to rotate. Due to the meshing relationship between the lifting plate 4 and the threaded rod 33, the lifting plate 4 will move up and down along the axial direction of the threaded rod 33. The up and down movement of the lifting plate 4 will drive the top plate 41 and the top rod 45 to move together, and then lift or lower the pad 51 through the support plate 46. The tilt of the pad 51 makes it easier to clean the feces and dirt on the pad 51.

[0046] Reference Figure 4 , Figure 7 , Figure 8The top plate 41 has a placement groove 43, and arc-shaped blocks 44 are fixedly connected to both sides of the placement groove 43. The arc-shaped blocks 44 cooperate with the protrusions 71 to achieve the guiding function. The design of the arc-shaped blocks 44 allows them to smoothly contact and separate from the protrusions 71 as the lifting plate 4 moves, thereby causing the drain pipe 7 and the water collection tank 55 to sway left and right. A slider 56 is fixedly connected to the water collection tank 55. The slider 56 fixedly connected to the water collection tank 55 allows the water collection tank 55 to slide in the slide groove 54 opened on the floor slab 5. The slide groove 54 is opened on the floor slab 5, and the slider 56 is slidably installed in the slide groove 54. A support spring 57 is fixedly connected to the slider 56. The free end of the support spring 57 is fixedly connected to the slide groove 54. When the water collection tank 55 vibrates due to the movement of the lifting plate 4, the support spring 57 can make the water collection tank 55 quickly reset after being pushed, and move left and right repeatedly to facilitate the discharge of internal sewage.

[0047] Reference Figures 3-6 Several flushing pipes 6 are rotatably installed inside the inner floor 11, with the number of flushing pipes 6 corresponding to the number of floors. They are responsible for delivering high-pressure water flow. High-pressure nozzles 61 are fixedly connected to the flushing pipes 6. The high-pressure nozzles 61 are used to spray water in a high-pressure form to form a strong impact force for cleaning the surface of the pad 51. A mounting bracket 62 is fixedly connected to the flushing pipes 6. A mounting rod 63 is rotatably installed on the mounting bracket 62. A rotating plate 64 is fixedly connected to the mounting rod 63. A connecting plate 42 is fixedly connected to the top plate 41. A limiting groove 12 is opened on the inner floor 11. The top plate 41 and the connecting plate 42 are slidably installed inside the limiting groove 12. A connector 65 is fixedly connected to the top plate 41 and the connecting plate 42. The rotating plate 64 is rotatably installed inside the connector 65. As the lifting plate 4 moves up and down, the connecting plate 42 slides along the limiting groove 12, causing the connector 65 and the rotating plate 64 to move synchronously. This design allows the mounting rod 63 and the high-pressure nozzle 61 connected to it to automatically adjust their position as the lifting plate 4 moves, ensuring that the high-pressure water flow can always effectively cover and rinse the surface of the pad 51.

[0048] When the high-pressure nozzle 61 is activated, high-pressure water is rapidly ejected through the flushing pipe 6, creating a strong impact that effectively breaks down and washes away stubborn dirt on the pad 51. The design of the rotating plate 64 allows the high-pressure nozzle 61 to rotate within a certain range, further expanding the cleaning area and ensuring that every corner of the pad 51 is thoroughly cleaned. In addition, the flexible connection between the mounting bracket 62 and the mounting rod 63 also gives the high-pressure nozzle 61 a certain degree of freedom, allowing it to be finely adjusted according to the tilt angle and shape of the pad 51 to maintain the optimal cleaning angle. This adaptive design not only improves cleaning efficiency but also reduces water waste. During the cleaning process, the coordinated work of the lifting unit and the flushing system is particularly important. The drive motor 32 drives the threaded rod 33 to rotate, causing the lifting plate 4 to move up and down along a preset trajectory, while simultaneously adjusting the position of the high-pressure nozzle 61. This integrated operation mode makes the entire cleaning process smoother and more efficient.

[0049] Reference Figure 3 , Figure 9 , Figure 10A sludge storage tank 3 is fixedly connected to the outer floor 1, which is located above ground 2. The sludge storage tank 3 is located below ground 2 and is used to collect and store sewage from the upper floor. The outlet of the drain pipe 7 extends into the sludge storage tank 3 to ensure that sewage or waste can be smoothly discharged into the sludge storage tank 3 for storage. A threaded rod 33 is rotatably installed in the sludge storage tank 3, and a stirring rod 31 is fixedly connected to the threaded rod 33. The rotation of the threaded rod 33 can drive the stirring rod 31 to move. The function of the stirring rod 31 is to stir the sewage or waste in the sludge storage tank 3, which helps to promote decomposition, prevent sedimentation, or improve the efficiency of subsequent treatment. An adjustment groove 47 is opened on the lifting plate 4, and a moving rod 49 is slidably installed in the adjustment groove 47. The design of section 7 needs to ensure that the moving rod 49 can slide smoothly. A brush head 410 is fixedly connected to the moving rod 49. The brush head 410 is fitted against the inner wall of the sludge storage tank 3. The sliding movement of the moving rod 49 allows the brush head 410 to brush the inner wall of the sludge storage tank 3 from side to side. A return spring 48 is fixedly connected to the moving rod 49. The free end of the return spring 48 is fixedly connected to the adjustment groove 47. A toggle rod 411 is fixedly connected to the moving rod 49. The toggle rod 411 cooperates with the stirring rod 31. As the stirring rod 31 continues to rotate, it not only promotes the mixing and decomposition of sewage and waste in the sludge storage tank 3, but also realizes the automatic cleaning of the inner wall of the sludge storage tank 3 by the brush head 410 through periodic contact with the toggle rod 411. This design cleverly utilizes the rotational power of the stirring rod 31, enabling regular cleaning of the inner wall without the need for an additional drive device. This effectively prevents the accumulation of dirt on the pool wall, maintaining the cleanliness and efficiency of the sludge storage tank 3. When the stirring rod 31 rotates to the position where it contacts the actuating rod 411, the resulting thrust overcomes the resistance of the return spring 48, pushing the moving rod 49 to slide along the adjusting groove 47. During this process, the brush head 410 remains in close contact with the inner wall of the sludge storage tank 3, brushing left and right as the moving rod 49 slides, effectively removing stubborn dirt adhering to the inner wall. When the stirring rod 31 continues to rotate and disengages from the actuating rod 411, the return spring 48 quickly returns to its elasticity, pulling the moving rod 49 back to its original position, ready for the next cleaning action.

[0050] A method for collecting manure from pig farms in buildings also includes the following steps:

[0051] S1. Start the drive motor 32 to lower the lifting plate 4. The pad 51 loses the support of the support plate 46 and tilts. At the same time, turn on the high pressure nozzle 61 to spray water to wash the feces on the pad 51.

[0052] S2. When the lifting plate 4 descends, the arc block 44 and the protrusion 71 work together to squeeze the drain pipe 7, causing the drain pipe 7 and the water collection tank 55 to sway left and right to facilitate material discharge and prevent blockage. At the same time, the rotating plate 64 pulls the flushing pipe 6 to rotate, so that the high pressure nozzle 61 can be adjusted in angle with the tilt of the pad plate 51.

[0053] S3. When the drive motor 32 drives the threaded rod 33 to rotate, the stirring rod 31 on the threaded rod 33 stirs the fecal sludge in the sludge storage tank 3 to prevent solidification and blockage.

[0054] S4. As the lifting plate 4 descends, the brush head 410 fixedly connected to it scrubs and cleans the inner wall of the sludge storage tank 3 to prevent odors from being generated. At the same time, the actuating rod 411 on the brush head 410 moves left and right in conjunction with the rotation of the stirring rod 31, improving cleaning efficiency.

[0055] 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.

When the drive motor (32) drives the threaded rod (33) to rotate, the stirring rod (31) on the threaded rod (33) stirs the fecal sludge in the sludge storage tank (3) to prevent solidification and blockage. S4. As the lifting plate (4) descends, the brush head (410) fixedly connected to it scrubs and cleans the inner wall of the sludge storage tank (3) to avoid odor. At the same time, the lever (411) on the brush head (410) moves left and right while the stirring rod (31) rotates, improving cleaning efficiency.
