Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of livestock breeding, in particular to a manure automatic cleaning device for livestock breeding. BACKGROUND

[0002] In the process of large-scale livestock breeding, timely cleaning of manure is a key link to ensure clean breeding environment, reduce the spread of diseases and improve breeding efficiency. With the expansion of breeding scale, the traditional manual cleaning method of manure not only has high labor intensity and low efficiency, but also cannot meet the high standard requirements of modern breeding for environmental control. Therefore, the automatic manure cleaning device has gradually become the mainstream demand in the industry.

[0003] According to the search, the Chinese patent with the publication number CN111789034B provides a pig house for livestock breeding, which is convenient for cleaning manure. The automatic manure scraping mechanism can move the scraping plate left and right, so that the pig manure on the leakage plate can be scraped into the collection box. The movement of the movable scraping plate can drive the manure plate cleaning assembly to work.

[0004] However, it is found in the use process that the manure produced in the breeding process is easy to form a hardened block structure due to factors such as long accumulation time and water content fluctuation. The cleaning components of the existing device are flat scraping plates, which can only scrape and push loose manure. There is no treatment method for hardened or clumped manure. The hardened manure is easy to be stuck in the gap of the leakage plate or the scraping path, causing the scraping plate to be stuck and not completely cleaned. On the other hand, the large pieces of manure that are not broken will not only occupy a large space and easily block the subsequent conveying pipeline, but also affect the efficiency of subsequent solid-liquid separation, fermentation and other resource utilization processes, increasing the subsequent processing cost.

[0049] When cleaning the manure of livestock breeding, the output shaft of the first servo motor 207 drives the crushing roller 102 to rotate around its own axis inside the feeding hopper 101. Since the two ends of the crushing roller 102 and the fine crushing roller 201 are respectively sleeved with pulleys 205, and the wheel grooves of the two pulleys 205 on the same side are connected by a belt 206 for 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 of the pulley 205 and the belt 206.

[0050] The outer periphery wall of the fine crushing roller 201 is slidingly connected with the groove walls of the circular arc grooves 202 opened at both ends of the feeding hopper 101. The center of the circular arc groove 202 is collinear with the axis of the crushing roller 102. Since the radius of the circular arc groove 202 is fixed, when the fine crushing roller 201 slides along the circular arc groove 202, the distance between its axis and the axis of the crushing roller 102 is always equal to the radius of the circular arc groove 202. This sliding fit structure ensures that the fine crushing roller 201 always maintains a stable running track during rotation, avoiding deviation. After the breeding manure enters the feeding hopper 101, it first contacts the rotating crushing roller 102. The crushing roller 102 preliminarily crushes the hardened block structure in the manure due to accumulation and fluctuation of water content, and breaks up the large block hardened manure.

[0051] As the cleaning box 100 moves, the preliminarily crushed manure then enters the crushing range of the fine crushing roller 201. The fine crushing roller 201 rotates to drive the scraper 204 to move synchronously. The fine crushing roller 201 further crushes the preliminarily crushed manure. The scraper 204 adapts to the delivery of manure particles of different crushing degrees along the fine crushing roller 201, reducing the jam caused by the hardness difference of the manure. The manure preliminarily crushed by the crushing roller 102 and further crushed by the fine crushing roller 201 is delivered to the cleaning box 100 inside by the delivery assembly 300 and the shoveling assembly 400 for collection. This facilitates the rapid decomposition of the hardened block-shaped manure, reduces the jamming of the equipment caused by the manure stuck in the cleaning path, reduces the residue of the manure in the feeding hopper 101 and the cleaning path, and reduces the occupied space in the cleaning box 100, providing convenience for subsequent delivery and subsequent solid-liquid separation, fermentation and other resource utilization processing links.

[0052] Before cleaning the manure of livestock breeding, the two visual recognition cameras 108 installed on the top surface of the cleaning box 100 are used to identify the accumulation position and range of the manure in the breeding area in real time. After determining the cleaning target, the driving wheel 104 drives the entire device to move to the specified cleaning area. If different breeding scenarios need to be adapted, the first cylinder 107 drives the bracket 105 connected with the driving wheel 104 to slide along the limiting block 106, thereby adjusting the inclination of the cleaning box 100 and the height of the feeding hopper 101, achieving adaptation to the manure accumulation position and adapting to the manure cleaning use in multiple breeding scenarios.

[0053] During the fine crushing process of the feces, the sliding rod 209 fixedly connected to the outer wall of the sleeve ring 208 slides along the positioning block 211, the first spring 210 sleeved on the outer periphery of the sliding rod 209 is self-adaptingly stretched and contracted according to the resistance during the crushing of the feces, the impact on the fine crushing roller 201 is buffered, and the damage of the equipment caused by the sudden change of the hardness of the feces is avoided; meanwhile, the scraper 204 in the groove 203 of the fine crushing roller 201 is closely attached to the feces under the elastic action of the second spring 213, the fine crushing effect is further improved, and the feces residue is reduced;

[0054] The feces after the fine crushing 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, the plurality of worm gear teeth 305 sleeved on the outer peripheral wall of the rotating shaft 304 meshes with the worm wheel 303 to drive the plurality of conveying rollers 301 to synchronously rotate, and the push plate 302 fixedly connected to the outer peripheral wall of the conveying roller 301 rotates with the roller body to push the feces into the interior of the cleaning box 100;

[0055] If the distance between the shovel block 401 and the ground is adjusted to facilitate the fine feces to enter the top surface of the triangular block 103, the piston rod of the second pneumatic cylinder 406 pushes the push block 407 and the T-shaped block 402 fixedly connected thereto to slide along the clamping 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 adhesion degree of the shovel block 401 to the ground, meanwhile, the damage of the shovel block 401 caused by the impact in the use process is reduced, the feces are conveniently scooped up and accumulated into the top surface of the triangular block 103, and the feces residue during the cleaning of the feces is reduced;

[0056] After the feces are conveyed into the cleaning box 100 for collection, the piston rod of the third pneumatic cylinder 510 drives the baffle 509 to slide upward to open 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 to drive the inclined block 503 to slide along the guide rail 504; the upper end of the inclined block 503 slides in the sliding groove 502 on the bottom surface of the flap 501 to push the flap 501 to rotate around the rotating connection point of the cleaning box 100, the feces are pushed to the discharge chute 508 along the inclined surface of the flap 501 to be discharged, and the collection of the feces is completed;

[0057] After the cleaning operation is completed, the water pump 604 on the top surface of the supporting block 602 conveys the external cleaning water or disinfecting water into the cleaning pipe 601 through the threaded pipe 605, the plurality of nozzles 603 communicated with the bottom surface of the cleaning pipe 601 spray out the water to clean and disinfect the ground after the collection of the feces of the livestock breeding;

[0058] If the water outlet angle of the spray head 603 needs to be adjusted during cleaning, the fourth cylinder 609 is used, and the piston rod drives the circular shaft 608 to move, and the circular shaft 608 drives the cleaning pipe 601 to rotate around the rotating connection point of the support block 602 through the sliding sleeve 607, so that the spray head 603 can be cleaned at multiple angles.

[0059] Working principle: when cleaning the manure of livestock breeding, the first servo motor 207 drives the crushing roller 102 to rotate around its axis in the feed hopper 101, and since the outer peripheral walls of the crushing roller 102 and the fine crushing roller 201 are respectively sleeved with pulleys 205, and the two pulleys 205 on the same side are frictionally connected through the belt 206, when the crushing roller 102 rotates, the fine crushing roller 201 in the crushing assembly 200 is synchronously driven through the transmission of the pulley 205 and the belt 206.

[0060] The outer peripheral wall of the fine crushing roller 201 is slidingly connected with the groove walls of the arc grooves 202 opened at both ends of the feed hopper 101, and the center of the arc groove 202 is collinear with the axis of the crushing roller 102. Since the radius of the arc groove 202 is fixed, when the fine crushing roller 201 slides along the arc groove 202, the distance between its axis and the axis of the crushing roller 102 is always equal to the radius of the arc groove 202. This sliding fit structure ensures that the fine crushing roller 201 always maintains a stable running track during rotation, avoiding deviation. After the breeding manure enters the feed hopper 101, it first contacts the rotating crushing roller 102, which preliminarily crushes the hardened block structure in the manure caused by accumulation and water content fluctuations, and breaks up the large and hard manure.

[0061] With the movement of the cleaning box 100, the preliminarily crushed manure then enters the crushing range of the fine crushing roller 201, and the fine crushing roller 201 rotates to drive the scraper 204 to move synchronously. The fine crushing roller 201 further crushes the preliminarily crushed manure, and the scraper 204 adapts to the delivery of manure particles of different crushing degrees along the fine crushing roller 201, reducing the jam caused by the hardness difference of the manure. The manure preliminarily crushed by the crushing roller 102 and further crushed by the fine crushing roller 201 is delivered to the cleaning box 100 by the delivery assembly 300 and the shoveling assembly 400 for collection. This facilitates the rapid decomposition of the hardened block-shaped manure, reduces the jamming of the manure in the cleaning path, reduces the residue of the manure in the feed hopper 101 and the cleaning path, and reduces the occupied space in the cleaning box 100, providing convenience for subsequent delivery and subsequent solid-liquid separation, fermentation and other resource utilization processes.

[0062] Before cleaning the livestock breeding manure, the two visual identification cameras 108 installed on the top surface of the cleaning box 100 are used to identify the accumulation position and range of the manure in the breeding area in real time, and after determining the cleaning target, the driving wheel 104 drives the entire device to move to the designated cleaning area; if it needs to adapt to different breeding scenes, the first cylinder 107 pushes the bracket 105 connected with the driving wheel 104 to slide along the limiting block 106, thereby adjusting the inclination of the cleaning box 100 and the height of the feeding hopper 101, and realizing the adaptation to the manure accumulation position, which adapts to the manure cleaning use of multiple breeding scenes.

[0063] During the fine crushing process of the manure, the sliding rod 209 connected with the outer wall of the sleeve ring 208 slides along the positioning block 211, the first spring 210 sleeved on the outer circumference of the sliding rod 209 is self-adaptingly stretched and contracted according to the resistance during the crushing of the manure, thereby buffering the impact on the fine crushing roller 201, avoiding the damage of the equipment caused by the sudden change of the hardness of the manure; at the same time, the scraper 204 in the groove 203 of the fine crushing roller 201 closely contacts the manure under the elastic action of the second spring 213, thereby further improving the fine crushing effect and reducing the manure residue.

[0064] The fine crushed manure is scooped up by the shovel block 401 and enters 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, the multiple worm gear teeth 305 sleeved on the outer circumferential wall of the rotating shaft 304 meshes with the worm gear 303 to drive the multiple conveying rollers 301 to rotate synchronously, and the push plate 302 connected with the outer circumferential wall of the conveying roller 301 rotates with the roller body to push the manure into the cleaning box 100.

[0065] If the distance between the shovel block 401 and the ground is adjusted, the push block 407 and the T-shaped block 402 connected therewith slide along the clamping block 405 by the piston rod of the second cylinder 406, the T-shaped block 402 drives the T-shaped rod 403 to push the shovel block 401 to slide along the triangular block 103, and the third spring 404 sleeved on the outer circumference of the T-shaped rod 403 adapts to the adhesion degree of the shovel block 401 and the ground, while reducing the damage to the shovel block 401 during the impact in the use process, facilitating the scooping up and accumulation of the manure into the top surface of the triangular block 103, and reducing the residue during the manure cleaning;

[0066] After the feces are collected in the inside of the cleaning box 100, the piston rod of the third cylinder 510 drives the baffle 509 to slide upward, the discharge chute 508 is opened, the output shaft of the third servo motor 507 drives the gear 506 to rotate, the gear 506 meshes with the rack 505, and the inclined block 503 slides along the guide rail 504; the upper end of the inclined block 503 slides in the chute 502 at the bottom surface of the flap 501, the flap 501 is pushed to overturn around the rotating connection point of the cleaning box 100, the feces are pushed to the discharge chute 508 along the inclined surface of the flap 501, and the feces collection is completed.

[0067] After the cleaning operation is completed, the water pump 604 on the top surface of the supporting block 602 delivers the external cleaning water or disinfecting water into the cleaning pipe 601 through the threaded pipe 605, the multiple spray heads 603 connected to the bottom surface of the cleaning pipe 601 spray out, the ground after the feces of the livestock and poultry breeding are collected is cleaned and disinfected;

[0068] If the water outlet angle of the spray head 603 needs to be adjusted during cleaning, the piston rod of the fourth cylinder 609 drives the circular shaft 608 to move, the circular shaft 608 drives the cleaning pipe 601 to rotate around the rotating connection point of the supporting block 602 through the sliding sleeve 607 and the pushing block 606 at one end of the cleaning pipe 601, and multi-angle cleaning of the spray head 603 is realized.

[0069] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
