Description

Technical Field

[0001] This invention belongs to the field of livestock feeding trough cleaning technology, and particularly relates to an automatic cleaning device for livestock feeding troughs. Background Technology

[0002] In livestock farming, the cleanliness of the feeding troughs directly affects the healthy growth of livestock and poultry, therefore, regular cleaning of the feeding troughs is necessary. To improve cleaning efficiency and reduce manual labor intensity, existing automatic cleaning equipment mostly adopts a structure in which a high-pressure water gun is mounted on a mobile cart. The mobile cart moves the high-pressure water gun along the extension direction of the feeding trough, using high-pressure water flow to specifically rinse the inner wall of the feeding trough, thus achieving automated cleaning of the feeding trough.

[0003] However, existing automatic cleaning equipment still faces many problems in practical applications, specifically: During the rinsing process, wastewater gradually accumulates on the inner wall of the bottom of the feeding trough and flows along the bottom. The flowing wastewater carries away dirt and impurities that have been washed off. When the high-pressure water gun nozzles rinse the subsequent areas of the inner wall of the bottom of the feeding trough, this wastewater carrying impurities will block the inner wall surface of the area to be rinsed, causing the high-pressure water flow to be unable to directly act on the dirt attachment points, thereby reducing the rinsing quality and resulting in incomplete cleaning in some areas. Furthermore, for the dry and hardened dirt attached to the side walls of the feeding trough, simple rinsing with high-pressure water flow is often insufficient to directly remove it. It is necessary to control the mobile cart to start and stop repeatedly or adjust the nozzle angle for multiple rinses. The rinsing effect is not ideal and significantly reduces the overall cleaning efficiency, while also causing a large amount of unnecessary waste of water resources and increasing breeding costs.

[0004] In summary, existing automatic cleaning equipment for livestock feed troughs based on mobile vehicles and high-pressure water guns has significant shortcomings in terms of cleaning hardened dirt, ensuring rinsing quality, and water resource utilization. It is difficult to meet the needs of efficient, safe, and economical livestock cleaning. Therefore, it is urgent to optimize and improve the existing equipment structure and cleaning methods. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automatic cleaning device for livestock feeding troughs, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides an automatic cleaning device for livestock feeding troughs, including a mobile water conveying system with a symmetrical isolation cover that can movably cover the upper port of the feeding trough. An isolation plate is fixed to the front of the isolation cover, which is adapted to block sewage in the feeding trough as the isolation cover moves, and to push the sewage along the cleaning path to wet the inner wall of the feeding trough. A ring-shaped rotating frame is rotatably mounted on the rear side of the isolation cover. Four sets of elastic telescopic components are arranged circumferentially on the ring-shaped rotating frame, and a strip-shaped scraper is installed at the end of each set of elastic telescopic components. The blade surface of the strip-shaped scraper is divided into a scraping section and a filtering section along its length, with the filtering section located at the front of the blade surface and the scraping section located at the rear of the blade surface. The strip-shaped scraper rotates under the drive of the ring-shaped rotating frame and is kept in contact with the inner wall of the feeding trough by the elastic telescopic components. A nozzle assembly is provided below the isolation cover corresponding to each set of strip-shaped scrapers. During the cleaning process, the strip scrapers rotate with the annular rotating frame and move along the cleaning path. First, the filtration section scoops up the sewage and impurities from the bottom of the trough and lifts them along the side wall of the trough, allowing the sewage to wet the higher parts of the side wall. Then, the scraping section thoroughly scrapes the inner wall of the trough. The nozzle assembly rotates closely following the corresponding strip scraper and rinses the scraped area. The isolation hood also has a waste collection bin, where the lifted impurities and sewage slide down for filtration and separation.

[0007] According to an advantageous embodiment, a water injection pipe is fixedly installed on the isolation plate, and an annular rotating frame is coaxially rotatably sleeved on the surface of the water injection pipe. A sealing sleeve is sleeved on the surface of the water injection pipe, and multiple water outlets connected to the corresponding sealing sleeves are opened on the surface of the water injection pipe at positions corresponding to the sealing sleeves. Both ends of the sealing sleeve are sealed at the connection points with the water injection pipe, and the sealing sleeve is connected to the corresponding nozzle assembly through a connecting pipe. The sealing sleeve is fixedly connected to the annular rotating frame through multiple connecting rods, so that the sealing sleeve rotates relative to the water injection pipe along with the annular rotating frame, thereby driving the corresponding nozzle assembly to rotate along with the corresponding strip scraper.

[0008] According to an advantageous embodiment, the mobile water supply system includes a mobile vehicle equipped with a water tank and a water pump. The water pump is fixedly connected to one end of a water supply pipe and a water injection pipe via a water delivery pipe. The other end of the water injection pipe is fixedly connected to a waste collection bin. Connecting arms are provided on both sides of the water tank and are connected to corresponding isolation covers.

[0009] According to an advantageous embodiment, the connecting arm includes a vertical adjusting arm disposed on one side of the water tank, a horizontal adjusting arm disposed on the vertical adjusting arm, a spring rod disposed on the horizontal adjusting arm, and the lower end of the spring rod being fixedly connected to the isolation cover.

[0010] According to an advantageous embodiment, two L-shaped guide plates symmetrically arranged front and back are fixedly provided on the side of the two isolation covers that are close to each other, and the vertical section of the L-shaped guide plates is rotatably provided with ball bearings.

[0011] According to an advantageous embodiment, the two vertical sections of the isolation cover are rotatably equipped with guide wheels near the lower position, and the lower end surfaces of the two vertical sections of the isolation cover are provided with sealing gaskets, and the outer wall of the isolation plate facing the feeding trough is provided with a removable sealing strip.

[0012] According to an advantageous embodiment, the annular rotating frame has four sets of evenly distributed strip-shaped sliding holes along its circumference. The strip-shaped sliding holes extend radially along the annular rotating frame. The elastic telescopic component includes a sliding plate that is slidably connected to the strip-shaped sliding holes. One end of the sliding plate movably passes through the annular rotating frame and is fixedly connected to the corresponding strip-shaped scraper. The other end of the sliding plate is fixedly connected to a spring together with the side wall of the corresponding strip-shaped sliding hole.

[0013] According to an advantageous embodiment, the isolation plate is provided with a drive assembly for driving the rotation of the annular rotating frame.

[0014] Compared with the prior art, the automatic cleaning device for livestock feeding troughs provided in this embodiment of the invention has the following beneficial effects: First, the isolation plate on the front side of the isolation cover continuously pushes the sewage accumulated in the trough to the uncleaned area faster and farther during the movement process. Compared with the sewage not needing to flow in the trough to wet the trough dirt, it can make the dry and hard dirt on the bottom and side walls uniformly and fully pre-wetted and softened, greatly improving the subsequent rinsing and removal effect of dry dirt.

[0015] Next, the strip scraper and high-pressure nozzle work together. As the scraper rotates, the filtration section evenly coats the bottom wastewater onto the sidewalls of the trough, wetting areas higher up where wastewater cannot spread and wet. The subsequent scraping section immediately mechanically scrapes away the wetted dirt, thoroughly removing the attachments. Then, the nozzle assembly applies high-pressure rinsing to the freshly scraped surface the instant the dirt is removed and before the wastewater flows back. Because there are no obstructions in this area, the water flow energy is fully applied to the remaining dirt, greatly improving rinsing quality. A single rinse is sufficient to achieve the cleaning standard, effectively avoiding repeated rinsing and water waste caused by wastewater obstruction in traditional cleaning methods.

[0016] Finally, the strip scraper lifts the wastewater and solid impurities together while scraping, guiding them to the waste collection bin inside the isolation hood for real-time solid-liquid separation. This design ensures that contaminants are continuously removed from the work area during the cleaning process, reducing the contaminant content in subsequent feed tank wastewater, thereby guaranteeing high cleanliness, high efficiency, and high water-saving performance throughout the long-distance feed tank cleaning process.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0025] Please refer to the following: Figures 1-3 An automatic cleaning device for livestock feed troughs includes a mobile water supply system 1, on which symmetrical U-shaped isolation covers 2 are installed. The isolation covers 2 are movably mounted on the upper port of the feed trough 15, and four sets of spray nozzle assemblies 3 are located below the isolation covers 2. The device is moved between two adjacent cages via the mobile water supply system 1, and then the two isolation covers 2 are adjusted and placed on the corresponding upper ports of the feed trough 15 within the cages, so that the spray nozzle assemblies 3 are inside the feed trough 15. As the mobile water supply system 1 moves the isolation covers 2, the spray nozzle assemblies 3 rinse the inner wall of the feed trough 15.

[0026] See Figures 1-3The mobile water supply system 1 includes a mobile vehicle, which is electric. The mobile vehicle is equipped with a water tank and a water pump. The water pump shares a power source with the mobile vehicle's motor. The water pump is connected to a nozzle assembly 3 via a water supply pipe. The nozzle assembly 3 integrates multiple linearly distributed nozzles. Connecting arms are located on both sides of the water tank, and these connecting arms are connected to corresponding isolation covers 2. The mobile vehicle drives the entire system to move along the feeding trough 15, while the water pump draws water from the water tank and delivers it to the nozzle assembly 3 via the supply pipe.

[0027] See Figure 1 To facilitate the stable placement of the isolation cover 2 on the upper port of the feeding trough 15, the connecting arm includes a vertical adjustment arm fixedly mounted on one side of the water tank. The vertical adjustment arm includes a first fixed base and a first insert plate. The first fixed base is welded to one side of the water tank, and the first insert plate is slidably inserted into the first fixed base and locked by a first locking bolt, allowing adjustment of the height of the isolation cover 2. A horizontal adjustment arm is connected to the upper end of the first insert plate. The horizontal adjustment arm includes a second fixed base and a second insert plate. The second fixed base is welded to the first insert plate, and the second insert plate is slidably inserted into the second fixed base and fixed by a second locking bolt, allowing adjustment of the horizontal position of the isolation cover 2. A spring rod is connected to the second insert plate, and the lower end of the spring rod is connected to the isolation cover 2, allowing adjustment of the pressing force between the isolation cover 2 and the upper port of the feeding trough 15.

[0028] See Figure 2 and Figure 5 To facilitate the movement of the isolation covers 2 at the upper port of the feeding trough 15, two symmetrical L-shaped guide plates 12 are welded to the sides of the two isolation covers 2 that are close to each other. The vertical sections of the L-shaped guide plates 12 are equipped with rotatable ball bearings. Both isolation covers 2 are stopped and restrained by their respective L-shaped guide plates 12, preventing the moving vehicle and isolation covers 2 from shifting during movement. Guide wheels 13 are rotatably installed near the lower part of the two vertical sections of the isolation covers 2, and sealing gaskets are provided on the lower end faces of both vertical sections of the isolation covers 2. This reduces the friction between the isolation covers 2 and the upper port of the feeding trough 15 during movement, facilitating movement and preventing cleaning fluid from splashing out from the connection between the vertical sections of the isolation covers 2 and the upper port of the feeding trough 15.

[0029] See Figure 2 , Figure 3 and Figure 5An isolation plate 4, adapted to the feeding trough 15, is welded to the front side of the isolation cover 2. As the isolation cover 2 covers the upper end of the feeding trough 15, the isolation plate 4 is inserted into the feeding trough 15, sealing it. The isolation plate 4 moves with the isolation cover 2, pushing the sewage inside the feeding trough 15 to flow in a single direction, wetting the dirt on the bottom inner wall of the feeding trough 15. Compared to the speed and distance of sewage flowing naturally along the bottom inner wall of the feeding trough 15 without the assistance of the isolation plate 4, the sewage flows more rapidly and farther with the assistance of the isolation plate 4. This allows the sewage to reach a farther position on the bottom inner wall of the feeding trough 15 to wet the dirt, facilitating subsequent rinsing. A removable sealing strip is provided on the outer side wall of the isolation plate 4 facing the feeding trough 15. This ensures that the isolation plate 4, once inserted into the feeding trough 15, can isolate the sewage inside the feeding trough 15.

[0030] See Figures 4-6 To prevent clumping impurities in the wastewater from affecting the rinsing effect of the nozzle assembly 3 on the inner wall of the feed trough 15, a ring-shaped rotating frame 5 is rotatably mounted on the rear side of the isolation plate 4. Four elastic telescopic components 6 are mounted on the ring-shaped rotating frame 5, and each elastic telescopic component 6 is equipped with a strip scraper 7. The strip scraper 7 has a bucket-shaped cross-section for easy scooping and lifting of wastewater. The front and rear halves of the blade surface of the strip scraper 7 are respectively designated as a scraping section 71 and a filtering section 72. A waste collection bin 8 is located inside the isolation cover 2. A filter plate is installed inside the waste collection bin 8, and a drain outlet (not shown in the figure) is provided at the bottom for wastewater discharge.

[0031] Under the action of the elastic telescopic component 6, the strip scraper 7 is always in contact with the inner wall of the feeding trough 15. The end face of the scraping section 71 of the strip scraper 7 is in close contact with the inner wall of the feeding trough 15 to scrape off the dirt attached to the inner wall of the feeding trough 15. The end face of the water filtering section 72 has a gap of 0.5cm with the inner wall of the feeding trough 15 to intercept the clumps of dirt and filter out the scraped wastewater from the gap. During the rotation of the strip scraper 7, the wastewater in the bottom inner wall of the feed trough 15 is first scraped up by the water filtration section 72 and the material scraping section 71 of the strip scraper 7 and moved upward along the side wall of the feed trough 15. The wastewater in the water filtration section 72 first wets the dirt that may remain on the inner wall of the side wall of the feed trough 15. Then, as it moves, the material scraping section 71 scrapes away the wetted dirt. Next, it is rinsed by the nozzle assembly 3 adjacent to the strip scraper 7. The wastewater is then lifted to a predetermined height by the rotation of the strip scraper 7 and automatically slides into the waste collection bin 8, filtering out the clumps of impurities in the wastewater.

[0032] See Figure 5 and Figure 6A drive assembly 14 for driving the rotation of the annular rotating frame 5 is provided on the isolation plate 4. The drive assembly 14 includes a gear ring coaxially fixedly mounted on the outer periphery of the annular rotating frame 5 and located near the side wall of the isolation plate 4. A gear that meshes with the gear ring is also rotatably mounted on the rear side of the isolation plate 4 near the gear ring. A motor is welded to the front side of the isolation plate 4, and the central shaft of the gear movably passes through the isolation plate 4 and is fixedly connected to the output shaft of the motor. The annular rotating frame 5 is rotated by the motor driving the gear and the gear ring.

[0033] See Figure 6 A water injection pipe 9 is fixedly installed on the isolation plate 4. A ring rotating frame 5 is coaxially rotated and sleeved on the surface of the water injection pipe 9 via bearings. One end of the water injection pipe 9 is fixedly connected to the water supply pipe, and the other end of the water injection pipe 9 is fixedly connected to the waste collection bin 8. A sealing sleeve 10 is sleeved on the surface of the water injection pipe 9, and multiple water outlets (not shown in the figure) are opened on the surface of the water injection pipe 9 corresponding to the positions of the sealing sleeve 10. Both ends of the sealing sleeve 10 are sealed at the connection points with the water injection pipe 9. The sealing sleeve 10 is connected to the corresponding nozzle assembly 3 through a connecting pipe 11. The sealing sleeve 10 is fixedly connected to the ring rotating frame 5 through multiple connecting rods, so that the sealing sleeve 10 rotates relative to the water injection pipe 9 with the ring rotating frame 5, thereby driving the corresponding nozzle assembly 3 to rotate with the scraping section 71 of the corresponding strip scraper 7, and rinsing the inner wall of the trough 15 after the scraped section 71 has removed the dirt.

[0034] See Figure 5 and Figure 6 To ensure that the strip scraper 7 always contacts the inner wall of the trough 15 during rotation, four sets of evenly distributed strip-shaped sliding holes are provided on the annular rotating frame 5 along its circumference. The strip-shaped sliding holes extend radially along the annular rotating frame 5. The elastic telescopic component 6 includes a sliding plate 61 that is slidably connected to the strip-shaped sliding holes. One end of the sliding plate 61 movably passes through the annular rotating frame 5 and is fixedly connected to the corresponding strip scraper 7. The other end of the sliding plate 61 is fixedly connected to the side wall of the corresponding strip-shaped sliding hole with a return spring 62. The strip scraper 7 contacts the inner wall of the trough 15. As the strip scraper 7 rotates continuously, the sliding plate 61 compresses the return spring 62 to adapt to the unevenness of the inner wall of the trough 15 at different positions.

[0035] It should be noted that the annular rotating frame 5 is usually located in the lower middle position inside the feeding trough 15, and the maximum extension length of the strip scraper 7 will not exceed the edge of the upper port of the feeding trough 15, thereby ensuring that the strip scraper 7 can rotate smoothly inside the feeding trough 15.

[0036] When the device is in operation: the entire device is moved between two adjacent cages by a mobile vehicle, and then the position of the isolation cover 2 is adjusted by the connecting arm so that both isolation covers 2 can be placed above the front port of the corresponding feed trough 15. The isolation plate 4 on the front side of the isolation cover 2 is inserted into the feed trough 15. Then the drive assembly 14 drives the ring rotating frame 5 to rotate, and at the same time the nozzle assembly 3 sprays out cleaning liquid. Next, the moving vehicle moves along the length of the feeding trough 15, causing the annular rotating frame 5 to move from front to back. During the movement, the nozzle assembly 3 rotates together with the strip scraper 7 on the annular rotating frame 5. The strip scraper 7 scoops up the generated wastewater from the bottom of the feeding trough 15 and lifts it along the side wall of the feeding trough 15. The water filtering section 72 of the rear half of the strip scraper 7 first lifts the wastewater along the side wall of the feeding trough 15 to wet any dirt that may be present on the side wall of the feeding trough 15. As the strip scraper 7 moves from front to back and rotates, its front scraping section 71 will initially scrape away the wetted dirt. Then, the nozzle assembly 3 further rinses the area on the inner wall of the feeding trough 15 that has been scraped by the scraping section 71. The wastewater and impurities in the area on the inner wall of the feeding trough 15 that has been scraped by the scraping section 71 are pushed aside. At this time, the rinsing by the nozzle assembly 3 is more thorough and free of clumping impurities. This achieves deep and efficient removal of dirt. Meanwhile, the strip scraper 7 can circulate and scoop up the clumps of impurities in the sewage to a predetermined height, and then drop them into the waste collection bin 8. This ensures that during the cleaning process of the long-span feeding trough 15, the dirt mixed in the sewage will not accumulate more and more as the rinsing progresses, thus avoiding the problem of clumps of dirt blocking the nozzle assembly 3 from rinsing the inner wall of the feeding trough 15.

[0037] This solution employs a progressive cleaning method for the feed trough, consisting of initial three-dimensional wetting, physical scraping, high-pressure rinsing, and impurity screening, thereby improving the rinsing efficiency and quality of the feed trough 15.

[0038] All-round three-dimensional wetting: After the isolation plate 4 on the front side of the isolation cover 2 is inserted into the feeding trough 15, it forms a sealed guiding structure, which promotes the rapid flow of sewage in a single direction. This allows the sewage to wet the inner wall of the bottom of the feeding trough 15, which is the most heavily contaminated area to be rinsed, more quickly and thoroughly, thus reducing the difficulty of rinsing the dirt on the inner wall of the bottom of the feeding trough 15. At the same time, when each set of strip scrapers 7 and nozzle assembly 3 rotates, the water filtering section 72 of the strip scraper 7 will scoop up and lift sewage and impurities along the vertical side wall of the feeding trough 15. This allows the sewage to wet the dry and hard dirt on the vertical side wall of the feeding trough 15. This ensures that both the inner wall of the bottom of the feeding trough 15 and the vertical side wall are pre-wetted before the scraping section 71 of the strip scraper 7 passes over them and before the nozzle assembly 3 rinses them. This changes the physical properties of the dirt, thereby reducing its adhesion and making it easier for the dirt to fall off the inner wall of the feeding trough 15.

[0039] Physical scraping: As the strip scraper 7 moves, the scraping section 71 mechanically scrapes the softened dirt on the bottom inner wall and vertical side wall of the feed trough 15, effectively loosening and removing stubborn dirt that is difficult to wash off by water alone.

[0040] High-pressure rinsing: The nozzle assembly 3, which rotates synchronously with the scraper, performs precise high-pressure rinsing on the scraped inner wall surface that is free of impurities and sewage, thus completely removing residual dirt.

[0041] Impurity removal: The wastewater containing clumps of impurities is poured into the waste collection bin 8 for filtration through the shovel-like design and rotating lifting action of the strip scraper 7. This process effectively prevents the accumulation and secondary obstruction of dirt along the cleaning path, ensuring that the high-pressure cleaning fluid sprayed from the nozzle assembly 3 always acts on a relatively clean surface throughout the entire cleaning process of the long-span trough 15, guaranteeing cleaning quality and improving cleaning efficiency.

[0042] In summary, compared to the traditional method of direct high-pressure spray rinsing, this solution directly reduces repeated rinsing and localized rework to achieve cleaning standards, improving rinsing quality while fundamentally saving water and reducing cleaning time. Furthermore, this solution greatly avoids splashing of cleaning solution and wastewater, making it particularly suitable for cleaning operations without needing to isolate livestock in cages.
