Description

Technical Field

[0001] This invention relates to the field of livestock breeding technology, and in particular to an automated manure cleaning device for livestock breeding. Background Technology

[0002] In large-scale livestock farming, timely cleaning of manure is a key link in ensuring a clean farming environment, reducing the spread of diseases, and improving farming efficiency. With the expansion of farming scale, traditional manual manure cleaning methods are not only labor-intensive and inefficient, but also fail to meet the high standards of environmental management required by modern farming. Therefore, automated manure cleaning devices are gradually becoming the mainstream demand in the industry. According to the search, Chinese patent with publication number CN111789034B provides a pigsty for easy manure cleaning in animal husbandry. The automatic manure scraping mechanism can move the movable manure scraper left and right, so as to scrape the pig manure on the manure slat into the collection box. The movement of the movable manure scraper can drive the manure slat cleaning component to work. However, during use, it was found that the manure produced during the breeding process easily forms a hardened and lumpy structure due to factors such as long accumulation time and fluctuations in moisture content. The existing device's cleaning component is a flat scraper, which can only scrape and push loose manure. It lacks a means to deal with hardened or lumpy manure. Hardened manure is easy to get stuck in the gaps of the manure slats or in the scraping path, causing the scraper to get stuck and the cleaning to be incomplete. On the other hand, large pieces of unbroken manure, after entering the collection box, not only take up a lot of space and are easy to block the subsequent conveying pipelines, but also affect the efficiency of subsequent resource-based treatment processes such as solid-liquid separation and fermentation, increasing subsequent treatment costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an automated manure cleaning device for livestock farming. After initial crushing by a crushing roller and further fine crushing by a fine crushing roller, the manure is transported to the cleaning box for collection via a conveying component and a shovel component. This facilitates the rapid decomposition of lumpy manure, reduces the risk of manure getting stuck in the cleaning path and causing equipment jams, reduces manure residue in the feed hopper and cleaning path, and reduces the space occupied in the cleaning box. This provides convenience for subsequent conveying and subsequent resource recovery processes such as solid-liquid separation and fermentation.

[0032] A cleaning assembly 600 is provided at the end of the cleaning box 100 away from the feed hopper 101. The cleaning assembly 600 includes a cleaning pipe 601, with two support blocks 602 rotatably connected to both ends of the cleaning pipe 601. Multiple nozzles 603 are connected to the bottom surface of the cleaning pipe 601. A water pump 604 is installed on the top surface of one of the support blocks 602. The output end of the water pump 604 is connected to the cleaning pipe 601 through a threaded pipe 605. A lever 606 is fixedly provided at one end of the cleaning pipe 601, and the lever 606 slides on the end.

External cleaning water or disinfectant water is transported to the cleaning pipe 601 through the threaded pipe 605 and sprayed out through multiple nozzles 603 connected to the bottom surface of the cleaning pipe 601 to clean and disinfect the ground after the collection of livestock manure.

[0033] When cleaning livestock manure, the output shaft of the first servo motor 207 drives the crushing roller 102 to rotate around its own axis inside the feed hopper 101. Since the outer peripheral walls of the two ends of the crushing roller 102 and the fine crushing roller 201 are respectively sleeved with pulleys 205, and the grooves of the two pulleys 205 on the same side are connected by a belt 206 to achieve friction transmission, when the crushing roller 102 rotates, it will drive the fine crushing roller 201 in the crushing assembly 200 to rotate synchronously through the transmission action of the pulleys 205 and the belt 206. The outer peripheral wall of the fine crushing roller 201 is slidably connected to the walls of the arc grooves 202 opened at both ends of the feed hopper 101. The center of the arc grooves 202 is collinear with the axis of the crushing roller 102. Since the radius of the arc grooves 202 is fixed, when the fine crushing roller 201 slides along the arc grooves 202, the distance between its axis and the axis of the crushing roller 102 is always equal to the radius of the arc grooves 202. This sliding fit structure ensures that the fine crushing roller 201 maintains a stable running trajectory during rotation and avoids deviation. After the livestock manure enters from the feed hopper 101, it first contacts the rotating crushing roller 102. The crushing roller 102 performs preliminary crushing on the clump-like structure formed by accumulation and fluctuation of moisture content in the manure, breaking up large clumps of manure. As the cleaning box 100 moves, the initially crushed manure then enters the crushing range of the fine crushing roller 201. When the fine crushing roller 201 rotates, it drives the scraper 204 to move synchronously. The fine crushing roller 201 further crushes the initially crushed manure. The scraper 204 adapts to the conveying of manure particles of different degrees of fineness along the extension and retraction of the fine crushing roller 201, reducing jamming caused by differences in manure hardness. After being initially crushed by the crushing roller 102 and further crushed by the fine crushing roller 201, the manure is conveyed to the inside of the cleaning box 100 for collection through the conveying component 300 and the shovel component 400. This facilitates the rapid decomposition of lumpy manure, reduces the amount of manure stuck in the cleaning path that causes equipment jamming, reduces the amount of manure residue in the feed hopper 101 and the cleaning path, and reduces the space occupied in the cleaning box 100, providing convenience for subsequent conveying and subsequent resource recovery processes such as solid-liquid separation and fermentation. Before cleaning livestock manure, two visual recognition cameras 108 installed on the top of the cleaning box 100 are used to identify the location and extent of manure accumulation in the breeding area in real time. After determining the cleaning target, the drive wheel 104 drives the entire device to move to the designated cleaning area. If it is necessary to adapt to different breeding scenarios, the piston rod of the first cylinder 107 pushes the bracket 105 fixed to the drive wheel 104 to slide along the limit block 106, thereby adjusting the tilt of the cleaning box 100 and the height of the feed hopper 101 to adapt to the manure accumulation position and adapt to the manure cleaning use of multiple breeding scenarios. During the process of finely crushing feces, the slide rod 209 fixed to the outer wall of the collar 208 slides along the positioning block 211. The first spring 210 sleeved on the outer periphery of the slide rod 209 adaptively expands and contracts according to the resistance during the crushing of feces, buffering the impact on the fine crushing roller 201 and preventing equipment damage due to sudden changes in the hardness of feces. At the same time, the scraper 204 in the groove 203 of the fine crushing roller 201 fits tightly against the feces under the elastic action of the second spring 213, further improving the crushing effect and reducing fecal residue. After being finely crushed, the feces are scooped up by the shovel block 401 and enter the top surface of the triangular block 103. At this time, the output shaft of the second servo motor 307 drives the outer rotating shaft 304 to rotate. Multiple worm gear teeth 305 sleeved on the outer peripheral wall of the rotating shaft 304 mesh with the worm wheel 303 to drive multiple conveying rollers 301 to rotate synchronously. The push plate 302 fixed to the outer peripheral wall of the conveying roller 301 rotates with the roller body, pushing the feces into the cleaning box 100. When the distance between the shovel block 401 and the ground is adjusted, so that the finely crushed feces can easily enter the top surface of the triangular block 103, the piston rod of the second cylinder 406 pushes the push block 407 and the T-shaped block 402 fixed thereto to slide along the locking block 405. The T-shaped block 402 drives the T-shaped rod 403 to push the shovel block 401 to slide along the triangular block 103. The third spring 404 sleeved on the outer periphery of the T-shaped rod 403 adapts to the fit between the shovel block 401 and the ground, while reducing the damage to the shovel block 401 during use due to impact. This makes it easier to shovel up the feces and accumulate them into the top surface of the triangular block 103, reducing the residue during feces cleaning. After the feces are collected inside the cleaning box 100, as the cleaning box 100 moves to a suitable subsequent processing position, the piston rod of the third cylinder 510 drives the baffle 509 to slide upward, opening the discharge chute 508. Then, the output shaft of the third servo motor 507 drives the gear 506 to rotate. The gear 506 meshes with the rack 505, driving the tilting block 503 to slide along the guide rail 504. The upper end of the tilting block 503 slides in the groove 502 on the bottom surface of the flip plate 501, pushing the flip plate 501 to flip around the rotation connection point with the cleaning box 100, pushing the feces along the inclined surface of the flip plate 501 to the discharge chute 508 for discharge, thus completing the feces collection. After the cleaning operation is completed, the water pump 604 on the top surface of the support block 602 will transport the external cleaning water or disinfectant water to the cleaning pipe 601 through the threaded pipe 605, and spray it out through the multiple nozzles 603 connected to the bottom surface of the cleaning pipe 601 to clean and disinfect the ground after the collection of livestock manure. If it is necessary to adjust the water outlet angle of the nozzle 603 during cleaning, the piston rod of the fourth cylinder 609 drives the round shaft 608 to move. The round shaft 608 pushes the toggle block 606 at one end of the cleaning tube 601 through the sliding sleeve 607, so that the cleaning tube 601 rotates around the rotation connection point with the support block 602, thereby realizing multi-angle cleaning of the nozzle 603.

[0034] Working principle: When cleaning livestock manure, the output shaft of the first servo motor 207 drives the crushing roller 102 to rotate around its own axis inside the feed hopper 101. Since the outer peripheral walls of the two ends of the crushing roller 102 and the fine crushing roller 201 are respectively sleeved with pulleys 205, and the grooves of the two pulleys 205 on the same side are connected by a belt 206 to achieve friction transmission, when the crushing roller 102 rotates, it will synchronously drive the fine crushing roller 201 in the crushing component 200 to rotate through the transmission action of the pulleys 205 and the belt 206. The outer peripheral wall of the fine crushing roller 201 is slidably connected to the walls of the arc grooves 202 opened at both ends of the feed hopper 101. The center of the arc grooves 202 is collinear with the axis of the crushing roller 102. Since the radius of the arc grooves 202 is fixed, when the fine crushing roller 201 slides along the arc grooves 202, the distance between its axis and the axis of the crushing roller 102 is always equal to the radius of the arc grooves 202. This sliding fit structure ensures that the fine crushing roller 201 maintains a stable running trajectory during rotation and avoids deviation. After the livestock manure enters from the feed hopper 101, it first contacts the rotating crushing roller 102. The crushing roller 102 performs preliminary crushing on the clump-like structure formed by accumulation and fluctuation of moisture content in the manure, breaking up large clumps of manure. As the cleaning box 100 moves, the initially crushed manure then enters the crushing range of the fine crushing roller 201. When the fine crushing roller 201 rotates, it drives the scraper 204 to move synchronously. The fine crushing roller 201 further crushes the initially crushed manure. The scraper 204 adapts to the conveying of manure particles of different degrees of fineness along the extension and retraction of the fine crushing roller 201, reducing jamming caused by differences in manure hardness. The manure, after initial crushing by the crushing roller 102 and further crushing by the fine crushing roller 201, is conveyed to the inside of the cleaning box 100 for collection through the conveying component 300 and the shovel component 400. This facilitates the rapid decomposition of lumpy manure, reduces the amount of manure stuck in the cleaning path that causes equipment jamming, reduces manure residue in the feed hopper 101 and the cleaning path, and reduces the space occupied in the cleaning box 100, providing convenience for subsequent conveying and subsequent resource recovery processes such as solid-liquid separation and fermentation.

[0035] Before cleaning livestock manure, two visual recognition cameras 108 installed on the top of the cleaning box 100 are used to identify the location and extent of manure accumulation in the breeding area in real time. After determining the cleaning target, the drive wheel 104 drives the entire device to move to the designated cleaning area. If it is necessary to adapt to different breeding scenarios, the piston rod of the first cylinder 107 pushes the bracket 105 fixed to the drive wheel 104 to slide along the limit block 106, thereby adjusting the tilt of the cleaning box 100 and the height of the feed hopper 101 to adapt to the manure accumulation position and adapt to the manure cleaning use of multiple breeding scenarios. During the process of finely crushing the feces, the slide rod 209 fixed to the outer wall of the collar 208 slides along the positioning block 211. The first spring 210 sleeved on the outer periphery of the slide rod 209 adaptively expands and contracts according to the resistance during the crushing of the feces, buffering the impact on the fine crushing roller 201 and preventing equipment damage due to sudden changes in the hardness of the feces. At the same time, the scraper 204 in the groove 203 of the fine crushing roller 201 fits tightly against the feces under the elastic action of the second spring 213, further improving the crushing effect and reducing fecal residue.

[0036] After being finely crushed, the feces are scooped up by the shovel block 401 and enter the top surface of the triangular block 103. At this time, the output shaft of the second servo motor 307 drives the outer rotating shaft 304 to rotate. Multiple worm gear teeth 305 sleeved on the outer peripheral wall of the rotating shaft 304 mesh with the worm wheel 303 to drive multiple conveying rollers 301 to rotate synchronously. The push plate 302 fixed to the outer peripheral wall of the conveying roller 301 rotates with the roller body, pushing the feces into the cleaning box 100. When the distance between the shovel block 401 and the ground is adjusted, so that the finely crushed feces can easily enter the top surface of the triangular block 103, the piston rod of the second cylinder 406 pushes the push block 407 and the T-shaped block 402 fixed thereto to slide along the locking block 405. The T-shaped block 402 drives the T-shaped rod 403 to push the shovel block 401 to slide along the triangular block 103. The third spring 404 sleeved on the outer periphery of the T-shaped rod 403 adapts to the fit between the shovel block 401 and the ground, while reducing the damage to the shovel block 401 during use due to impact. This makes it easier to shovel up the feces and accumulate them into the top surface of the triangular block 103, reducing the residue during feces cleaning. After the feces are collected inside the cleaning box 100, as the cleaning box 100 moves to a suitable subsequent processing position, the piston rod of the third cylinder 510 drives the baffle 509 to slide upward, opening the discharge chute 508. Then, the output shaft of the third servo motor 507 drives the gear 506 to rotate. The gear 506 meshes with the rack 505, driving the tilting block 503 to slide along the guide rail 504. The upper end of the tilting block 503 slides in the groove 502 on the bottom surface of the flip plate 501, pushing the flip plate 501 to rotate around the rotation connection point with the cleaning box 100, pushing the feces along the inclined surface of the flip plate 501 to the discharge chute 508 for discharge, thus completing the feces collection.

[0037] After the cleaning operation is completed, the water pump 604 on the top surface of the support block 602 will transport the external cleaning water or disinfectant water to the cleaning pipe 601 through the threaded pipe 605, and spray it out through the multiple nozzles 603 connected to the bottom surface of the cleaning pipe 601 to clean and disinfect the ground after the collection of livestock manure. If it is necessary to adjust the water outlet angle of the nozzle 603 during cleaning, the piston rod of the fourth cylinder 609 drives the round shaft 608 to move. The round shaft 608 pushes the toggle block 606 at one end of the cleaning tube 601 through the sliding sleeve 607, so that the cleaning tube 601 rotates around the rotation connection point with the support block 602, thereby realizing multi-angle cleaning of the nozzle 603.
