Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a fully automated sheep manure separation and recycling system. Background Technology

[0002] In large-scale sheep farming, the daily cleaning and treatment of sheep manure is crucial for ensuring a safe farming environment, controlling disease transmission, and improving farming efficiency. Traditional sheep pens typically use a floor-level rearing system, where sheep manure accumulates directly on the floor, requiring regular manual cleaning by farm workers – a labor-intensive and inefficient process. Some farms use slatted floors or raised structures, allowing manure to fall through gaps into manure ditches. However, the fallen manure is usually a mixture of wet and dry waste, requiring additional separation and treatment, increasing the cost and complexity of manure management.

[0003] Furthermore, existing sheep pens mostly use solid structures or enclosed designs at the bottom, resulting in poor permeability. Sheep excrement and the damp environment easily breed bacteria and produce ammonia, affecting the health and growth performance of the sheep. With the expansion of breeding scale, how to achieve automated dry and wet separation of sheep manure, reduce the intensity of manual cleaning, and maintain the permeability of the sheep pen bottom has become an urgent technical problem to be solved in large-scale sheep farming. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of the prior art and provide a fully automated sheep manure separation and recycling system.

[0005] The technical solution adopted by this invention to achieve its technical objective is: a fully automatic sheep manure separation and recycling system, comprising: The floor slab forms a space of a predetermined height between itself and the ground. A sheep pen is installed on the floor slab, and the bottom of the sheep pen is provided with a grid bottom plate, which connects the bottom of the sheep pen with the space below the floor slab. A sheep manure dry-wet separation system, installed in the space below the floor slab, includes: The first conveyor frame is equipped with a rotating roller and a mesh conveyor belt. The mesh conveyor belt is driven by the rotating roller and is used to receive sheep manure discharged through the mesh bottom plate. A guide plate is inclinedly set below the first conveyor frame to receive urine that falls after being filtered by the mesh conveyor belt, and to transport the urine to the urinal through the collection trough and the conveying pipe. A scraper, fixed to the first conveyor frame and in contact with the surface of the mesh conveyor belt, is used to scrape off solid feces from the mesh conveyor belt. The second conveyor frame is located below the first conveyor frame. A belt conveyor is installed on the second conveyor frame to receive the solid feces scraped off by the scraper and transport them to the septic tank.

[0006] Preferably, the preset height between the floor slab and the ground is 2m to 2.5m.

[0007] Preferably, the grid base plate is embedded within the floor slab.

[0008] Preferably, the sheep pen includes a horizontal partition and a vertical partition, the horizontal partition and the vertical partition interlocking to evenly divide the interior of the sheep pen into multiple rectangular management spaces.

[0009] Preferably, the bottoms of both the transverse partition and the longitudinal partition are fixedly seated on the grid base plate.

[0010] Preferably, a drive motor is connected to the rotating roller at one end of the first conveyor frame via a belt drive, and the drive motor is fixedly mounted on the first conveyor frame.

[0011] Preferably, the mesh conveyor belt is a perforated structure conveyor belt, whose mesh aperture allows urine to pass through while intercepting particulate solid feces.

[0012] Preferably, the guide plate is fixedly connected to the load-bearing column below the floor slab via a mounting bracket.

[0013] Preferably, one end of the collection trough is fixed to the first conveyor frame by a connecting rod, and the other end is fixed to the second conveyor frame by a connecting rod.

[0014] Preferably, the scraper is positioned above the belt conveyor and at the end of the mesh conveyor belt.

[0015] The working principle of this fully automated sheep manure separation and recycling system is as follows: The load-bearing columns elevate the floor slab, creating a space 2m to 2.5m high between the bottom and the ground. The sheep pen is connected to this space via a mesh floorboard embedded in the floor slab, allowing sheep manure to fall into the wet-dry separation system. The mesh conveyor belt on the first conveyor frame receives the manure, while urine is filtered through the mesh and falls onto an inclined guide plate. It then flows along the guide plate into a collection trough and is discharged into a urine tank via a conveying pipe. Solid manure is transported by the mesh conveyor belt to a scraper where it is scraped. After falling onto the belt conveyor, the waste is sent to the manure pit. The sheep pen is also equipped with a sheep manure cleaning system. A dual-shaft motor synchronously drives two lead screws to rotate. Through the screw sleeve, the rod moves along the sliding groove at the bottom of the longitudinal partition under the limit of the slider and the slide rail. This causes the cleaning scraper below the rod to clean the grid bottom plate. At the same time, the sprayer above the rod is connected to the water tank through the conveying hose and sprays water jets onto the grid bottom plate for cleaning. The cleaning wastewater and residue fall through the grid bottom plate to the mesh conveyor belt and are discharged into the urine pit and manure pit respectively according to the above separation process.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This fully automated sheep manure separation and recycling system elevates the floor slab through load-bearing columns and installs a grid bottom plate embedded in the floor slab at the bottom of the sheep pen, keeping the bottom of the sheep pen connected to the space below the floor slab. This effectively maintains the permeability of the bottom of the sheep pen, reduces bacterial growth caused by a damp environment, and improves the living environment for the sheep.

[0017] This fully automated sheep manure separation and recycling system uses a mesh conveyor belt to collect sheep manure. The mesh structure allows urine to be automatically filtered and fall to the guide plate, while solid manure remains on the conveyor belt and is transported to the scraper for automatic scraping. This achieves automated dry and wet separation and classified recycling of sheep manure, eliminating the need for additional separation processes and reducing subsequent processing costs.

[0018] This fully automated sheep manure separation and recycling system collects filtered urine through a guide plate, a collection trough, and a conveying pipe, and discharges it into a urine pool to prevent urine from polluting the ground and keep the breeding environment clean.

[0019] This fully automated sheep manure separation and recycling system uses a scraper to automatically remove solid manure from the mesh conveyor belt, preventing belt blockage and ensuring continuous and stable operation of dry and wet separation.

[0020] This fully automated sheep manure separation and recycling system divides the sheep pen into multiple rectangular management spaces evenly through horizontal and vertical partitions, enabling modular management of the sheep pen and facilitating classified breeding and refined operation.

[0021] This fully automated sheep manure separation and recycling system uses a dual-axis motor to drive a lead screw, which moves the rod along a sliding groove. This allows the cleaning scraper to automatically clean the grid bottom plate, while a sprayer sprays water jets onto the grid bottom plate for cleaning. This achieves automatic cleaning of the grid bottom plate without the need for manual entry into the sheep pen, reducing labor intensity and avoiding disturbing the sheep.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1:

[0032] Please see Figures 1-2 An automated sheep manure separation and recycling system is installed in a factory building 1 and is used in conjunction with a sheep pen 4. The factory building 1 includes a floor slab 101 and load-bearing columns 102. The load-bearing columns 102 support the floor slab 101, so that there is a height of 2m to 2.5m between the bottom of the floor slab 101 and the ground.

[0033] A sheep pen 4 is installed on the floor slab 101. A grid base plate 403 is embedded in the floor slab 101, connecting the bottom of the sheep pen 4 to the space below the floor slab 101, ensuring permeability. The grid base plate 403 maintains permeability at the bottom of the sheep pen 4 and allows sheep manure to be discharged through it to a dry-wet separation system below the floor slab 101 for separation and subsequent recycling.

[0034] In this embodiment, a sheep manure dry-wet separation system is installed below the floor slab 101. The sheep manure dry-wet separation system is located in the space below the floor slab 101. The sheep manure dry-wet separation system includes a first conveyor frame 2, with rotating rollers 201 rotatably installed at both ends of the first conveyor frame 2. The rotating rollers 201 are connected by a mesh conveyor belt 202. The mesh conveyor belt 202 is a conveyor belt with a mesh structure. The mesh structure in the mesh conveyor belt 202 allows urine in the sheep manure to pass through, while retaining the granular manure to continue to stay on the mesh conveyor belt 202 for transportation. Thus, after the sheep manure is discharged onto the mesh conveyor belt 202 through the mesh bottom plate 403, the urine of the sheep is filtered by the mesh conveyor belt 202 and discharged below, while the feces of the sheep continue to stay on the mesh conveyor belt 202.

[0035] In this embodiment, a drive motor 203 is connected to the rotating roller 201 at one end of the first conveyor frame 2 via a belt drive. The drive motor 203 is also fixedly installed on the first conveyor frame 2 to drive the rotating roller 201 to rotate, so that the mesh conveyor belt 202 can be driven and transported.

[0036] In this embodiment, a guide plate 3 is inclinedly arranged below the first conveyor frame 2. The guide plate 3 is fixedly connected to the load-bearing column 102 through the mounting frame. A collection trough 301 is provided at the lower end of the guide plate 3. A conveying pipe 302 is fixedly connected to the bottom of the collection trough 301. The conveying pipe 302 is connected to the urinal.

[0037] In this embodiment, a second conveyor frame 303 is provided on one side of the guide plate 3 and the collecting trough 301. The second conveyor frame 303 is located below the first conveyor frame 2. One end of the collecting trough 301 is fixed on the first conveyor frame 2 by a connecting rod, and the other end is fixed on the second conveyor frame 303 by a connecting rod.

[0038] In this embodiment, a belt conveyor 304 is fixedly installed at the top of the second conveyor frame 303, and one end of the belt conveyor 304 is connected to the manure pit. A scraper 204 is provided above the belt conveyor 304. The scraper 204 is fixed on the first conveyor frame 2, and the scraper 204 is in contact with the belt surface of the mesh conveyor belt 202 on its side. The scraper 204 is used to remove the sheep manure on the mesh conveyor belt 202, so that the sheep manure can fall onto the belt conveyor 304 and be transported to the manure pit.

[0039] When sheep manure is discharged onto the mesh conveyor belt 202 through the mesh bottom plate 403, the urine of the sheep is filtered through the mesh conveyor belt 202 and discharged onto the guide plate 3 to enter the collection tank 301 for unified collection, and then discharged into the urine pool through the conveying pipe 302; while the sheep manure continues to remain on the mesh conveyor belt 202. After being conveyed, the sheep manure on the mesh conveyor belt 202 is scraped off by the scraper 204 and falls onto the belt conveyor 304, and then is discharged into the manure pool through the belt conveyor 304, thus realizing the dry and wet separation of sheep manure.

[0040] In this embodiment, the sheep pen 4 includes a transverse partition 401 and a longitudinal partition 402. The transverse partition 401 and the longitudinal partition 402 are cross-fitted to evenly divide the interior of the sheep pen 4 into multiple rectangular management spaces. By evenly dividing the interior of the sheep pen 4 through the transverse partition 401 and the longitudinal partition 402, modular management of the sheep pen 4 is achieved.

[0041] Specifically, multiple transverse partitions 401 are provided. After the multiple transverse partitions 401 are placed horizontally in parallel, their bottoms are fixedly placed on the grid base plate 403. Multiple longitudinal partitions 402 are provided. After the multiple longitudinal partitions 402 are placed vertically in parallel, their bottoms are also fixedly placed on the grid base plate 403. At the same time, each pair of adjacent longitudinal partitions 402 cooperates with each pair of adjacent transverse partitions 401 to surround a rectangular space. Multiple spaces form a sheep pen 4, realizing modular management of the sheep pen 4.

[0042] Specifically, in use, the feces produced by the sheep in sheepfold 4 are discharged onto the mesh conveyor belt 202 below through the bottom mesh plate 403; the drive motor 203 drives the rotating roller 201 to drive the mesh conveyor belt 202. The urine in the feces is filtered through the mesh of the mesh conveyor belt 202 and falls onto the inclined guide plate 3, flowing into the collection trough 301 along the guide plate 3, and then being discharged into the urine pool through the conveying pipe 302; while the solid feces in the feces remain on the mesh conveyor belt 202 and are conveyed. When it is conveyed to the scraper 204, the scraper 204 scrapes the feces off the mesh conveyor belt 202 and drops it onto the belt conveyor 304 below, and then the belt conveyor 304 conveys it to the manure pool, thereby realizing the dry and wet separation and classified recycling of sheep manure. Implementation: 2:

[0043] Please see Figures 3-5 Based on the above embodiments, the fully automatic sheep manure separation and recycling system includes a sheep manure cleaning system 5 installed in the sheep pen 4. The sheep manure cleaning system 5 includes a rod 501, which is parallel to the transverse partition 401 and passes through and connects to the longitudinal partition 402. Another rod 501 is installed every other transverse partition 401. Both ends of the two rods 501 pass through the longitudinal partition 402 and are fixedly connected to a threaded sleeve 502. The threaded sleeve 502 is threadedly connected to a lead screw 503. The lead screw 503 is synchronously driven by a dual-axis motor 504, which is fixedly installed on the floor slab 101. The bottom end of the longitudinal partition 402 is provided with a sliding groove 6. The rod 501 passes through the sliding groove 6 and is connected to the sliding groove 6 in a limited sliding manner through the slider 7 and the slide rail 8. The slider 7 is fixedly installed on the outer wall of the rod 501 and the slide rail 8 is fixedly installed on the inner wall of the sliding groove 6, so that the rod 501 can move along the sliding groove 6 inside it.

[0044] By starting the dual-axis motor 504, its two drive shafts rotate simultaneously, thereby driving the two lead screws 503 to rotate simultaneously. Since the two lead screws 503 are threadedly connected to the screw sleeves 502 fixed at the top of the rod body 501, and the rod body 501 is restricted to sliding connection inside the sliding groove 6, when the two lead screws 503 rotate simultaneously, the rod body 501 can be driven to move inside the sliding groove 6 through the screw sleeves 502. By setting the thread direction of the lead screws 503, the relative movement of the two rod bodies 501 can be realized.

[0045] A cleaning scraper 505 is fixedly installed below the rod 501. The cleaning scraper 505 is set towards the grid base plate 403 and is used to clean the grid base plate 403. A sprayer 507 is fixedly installed on the top of the rod 501 by a diagonal brace 506. The nozzle of the sprayer 507 is set towards the cleaning scraper 505 and the grid base plate 403 for cleaning the grid base plate 403. The sprayer 507 is connected to a water tank 509 and a water pump (not shown in the figure) via a delivery hose 508. The water pump delivers water to the delivery hose 508 and the sprayer 507.

[0046] The movement of the rod 501 can drive the sprayer 507 and the cleaning scraper 505 to move synchronously. The sprayer 507 sprays water jets towards the cleaning scraper 505 and the grid base plate 403 to clean the grid base plate 403. At the same time, the cleaning scraper 507 cleans the grid base plate 403, achieving synchronous cleaning and washing of the grid base plate 403. The wastewater after cleaning is discharged into the urinal through the guide plate 3, the collection trough 301 and the conveying pipe 302.

[0047] The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0048] Specifically, in use, the dual-axis motor 504, which is fixedly installed on the floor slab 101, is started. The dual-axis motor 504 drives the two lead screws 503 to rotate synchronously. The lead screws 503 drive the rod body 501 to move along the sliding groove 6 through the screw sleeve 502. The rod body 501 maintains a limited sliding position under the cooperation of the slider 7 and the slide rail 8. When the rod body 501 moves, it drives the cleaning scraper 505 fixed below it to clean the grid bottom plate 403. At the same time, the sprayer 507 fixed above the rod body 501 through the diagonal support frame 506 sprays water jets towards the cleaning scraper 505 and the grid bottom plate 403 to clean the grid bottom plate 403. The fecal residue and wastewater collected from sweeping and washing fall together through the mesh bottom plate 403 to the mesh conveyor belt 202 below. Then, following the process of Example 1, the wastewater is discharged into the urinal through the guide plate 3, the collection trough 301 and the conveying pipe 302. The solid residue is transported by the mesh conveyor belt 202 and scraped off by the scraper 204 to the belt conveyor 304 and then sent to the septic tank.

[0049] The specific operating procedure of this fully automated sheep manure separation and recycling system is as follows: The feces produced by the sheep are discharged through the mesh bottom plate 403 to the mesh conveyor belt 202. The drive motor 203 drives the rotating roller 201 to drive the mesh conveyor belt 202. The urine is filtered through the mesh conveyor belt 202 and falls to the guide plate 3. It flows along the guide plate 3 into the collection trough 301 and then is discharged into the urine pool through the conveying pipe 302. Solid feces remain on the mesh conveyor belt 202 and are transported to the scraper 204. The scraper 204 scrapes the feces off the mesh conveyor belt 202 and onto the belt conveyor 304, which then transports them to the septic tank. When the mesh base plate 403 needs to be cleaned, the dual-axis motor 504 is started to drive the two lead screws 503 to rotate synchronously. The lead screws 503 drive the rod body 501 to move along the sliding groove 6 in cooperation with the slider 7 and the slide rail 8 through the screw sleeve 502. The rod body 501 drives the cleaning scraper 505 to clean the mesh base plate 403. At the same time, the sprayer 507 sprays water jets onto the mesh base plate 403 for cleaning. The cleaning wastewater and residue fall through the mesh base plate 403 to the mesh conveyor belt 202, and then are discharged into the urinal and septic tank respectively according to the above dry and wet separation process.

[0050] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of this invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this invention, or equivalent structural, procedural, or functional transformations made using the description and drawings of this invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this invention.
