Description

Technical Field

[0001] The present invention relates to an automatic manure cleaning machine, in particular to an automatic manure cleaning machine for the whole process of antibiotic-free laying hen breeding, belonging to the technical field of laying hen breeding equipment. Background Art

[0002] During the breeding process of laying hens, the cleaning of manure is a major problem faced by farmers. If the manure is not cleaned in time, it will accumulate, generating ammonia and other harmful gases, which is not good for the health of chickens and may lead to respiratory diseases. In addition, the wet manure is prone to breed bacteria and parasites, increasing the risk of disease transmission. Moreover, the accumulation of manure may affect the humidity and temperature of the chicken coop, leading to environmental deterioration and affecting the egg production rate. Currently, many farmers use belt-type manure cleaning machines for laying hens to clean manure. The manure is collected and conveyed in real time through a conveyor belt installed under the chicken cages to achieve automatic cleaning, significantly reducing manual intervention.

[0003] However, during the use of the belt-type manure cleaning machine, there is a certain gap between the scraper and the conveyor belt. Feathers are likely to get stuck at this position. When the feathers are stuck between the scraper and the conveyor belt, it is not only easy to cause manure accumulation, affecting the feeding, but also increases the wear of the conveyor belt. At the same time, the increased resistance of the conveyor belt is likely to cause the motor load to become larger, resulting in the burning of the motor. In addition, the belt-type manure cleaning machine does not clean thoroughly, and there is still manure residue on the surface of the conveyor belt, and timely disinfection cannot be carried out, affecting the use effect.

[0004] Therefore, an automatic manure cleaning machine for the whole process of antibiotic-free laying hen breeding is designed to optimize the above problems. Summary of the Invention

[0005] The main object of the present invention is to provide an automatic manure cleaning machine for the whole process of raising laying hens without antibiotics. By arranging a first guide roller and a second guide roller at the end of the conveyor belt, the first guide roller is located directly below the conveying roller, so that the conveyor belt has a larger end area. In addition, two groups of scrapers are arranged in parallel up and down at the end of the conveyor belt, and the scrapers can all slide horizontally. It is used in conjunction with the swapping mechanism composed of a shaft rod, a first sliding rod, a sliding ring, a push rod, a first sleeve, a pressing block, a first spring, a vertical plate, an arc plate, and a stop block on the frame. After the phenomenon of chicken feathers being stuck between a group of scrapers and the conveyor belt occurs, the scraper will be controlled to slide away from the conveyor belt. When the moving distance of the scraper reaches the critical condition of the swapping mechanism, the baffle plate where the chicken feathers are stuck will quickly move away from the conveyor belt, shaking off the chicken feathers, and another scraper will replace it to clean the manure. This makes the device not cause the driving motor to operate under heavy load due to stuck chicken feathers during use, nor cause significant wear to the conveyor belt, improving the service life of the equipment. By arranging a cleaning mechanism composed of a second sleeve, a pressing rod, a second spring, and a scraper on the frame, it does not contact the scraper for cleaning residual chicken manure in the initial state, but fits with the top of another scraper instead. It will only contact the bottom of the scraper when the position of the scraper participating in the cleaning reaches the critical value. When the position of the scraper is swapped, it will push the chicken manure on the surface of the scraper outward during the movement of the scraper for the next replacement use, making it more convenient to use. By arranging a cleaning mechanism composed of a water pipe, a high-pressure nozzle, a water receiving tank, a fixing plate, a second sliding rod, a U-shaped plate, a third spring, a water absorbing roller, and a pressing roller inside the protective shell, it can wash the conveyor belt again after the chicken manure is scraped off, and use the water absorbing roller to dry the water after the washing, ensuring the cleanliness of the conveyor belt surface and reducing the corrosion caused by chicken manure. By arranging a sterilization mechanism composed of a mounting plate, an ultraviolet lamp, a partition plate, a disinfection pipe, an atomizing nozzle, a cylinder body, a piston, a push-pull rod, a turntable, a cylindrical rod 1, a collar, a disinfectant liquid tank, a liquid inlet pipe, and a liquid discharge pipe inside the protective shell, it can first perform ultraviolet sterilization and then perform hypochlorous acid sterilization after the conveyor belt is cleaned. The ultraviolet pretreatment reduces the initial bacterial count, and then only a lower concentration of hypochlorous acid spraying is required to complete the secondary disinfection, ensuring the sterilization effect, not causing harm to the chickens, and not requiring isolated sterilization, improving the functionality of the device and having higher practicality.

[0017] The beneficial effects of the present invention are:

[0018] The invention provides an automatic manure cleaning integrated machine for laying hens without resistance breeding, wherein a first guide roller and a second guide roller are arranged at the end of the conveyor belt, and the first guide roller is located directly below the conveyor roller, so that the conveyor belt has a larger end area, and two groups of scrapers are arranged in parallel at the upper and lower ends of the conveyor belt, and the scrapers can slide horizontally, and then cooperate with the switching mechanism composed of the shaft rod, the first sliding rod, the sliding ring, the push rod, the first sleeve, the extrusion block, the first spring, the vertical plate, the arc plate and the stopper on the frame for use, so that after the phenomenon of chicken feathers being stuck between one group of scrapers and the conveyor belt occurs, the scrapers are controlled to slide in the direction away from the conveyor belt, and when the moving distance of the scrapers reaches the critical situation of the switching mechanism, the baffle with the chicken feathers stuck at this time will quickly move away from the conveyor belt to shake off the chicken feathers, and the other scraper will replace the cleaning of feces, so that the device will not cause the heavy load operation of the driving motor due to the stuck chicken feathers during use, and will not cause a large degree of wear on the conveyor belt, thereby improving the service life of the equipment;

[0019] By arranging a cleaning mechanism consisting of a second sleeve, a pressure rod, a second spring and a scraper on the frame, in the initial state, the cleaning mechanism does not contact the scraper for cleaning the residual chicken manure, but fits with the top of another scraper. When the moving position of the scraper involved in cleaning reaches a critical value, the cleaning mechanism will contact the bottom of the scraper. When the position of the scraper is swapped, the chicken manure on the surface of the scraper will be pushed outwards when the scraper moves, so that the scraper can be replaced and used next time, which is more convenient to use.

[0020] By arranging a cleaning mechanism composed of a water pipe, a high-pressure nozzle, a water receiving trough, a fixing plate, a second slide rod, a U-shaped plate, a third spring, a water suction roller and a pressure roller inside the protective shell, it is possible to wash the chicken manure after scraping it, and then use the water suction roller to absorb the water after washing, thereby ensuring the cleanliness of the conveyor belt surface and reducing the corrosion caused by chicken manure;

[0037] To make the technical personnel in the technical field more clear and definite about the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0038] As Figures 1 - 8 shown, this embodiment provides an automatic manure cleaning and integrating machine for the whole-process antibiotic-free breeding of laying hens, which includes a frame 1, conveying rollers 2 rotatably installed at both ends of the frame 1, a conveyor belt 3 located between the conveying rollers 2, and a driving motor 4 that provides power to the conveying rollers 2. A first guide roller 5 is rotatably installed between one end of the frame 1, and the first guide roller 5 is located directly below the conveying rollers 2. A second guide roller 6 is rotatably installed at the top of the frame 1 near one end of the first guide roller 5. The conveyor belt 3 passes under the bottom of the first guide roller 5 and over the top of the second guide roller 6. A scraper 7 is horizontally slidably arranged at one end of the frame 1 near the first guide roller 5. There are two groups of scrapers 7 arranged horizontally up and down. An inversion mechanism 8 for controlling the reverse movement of the two groups of scrapers 7 is provided at one end of the frame 1 near the scraper 7. Cleaning mechanisms 9 are provided at the ends of the frame 1 and above the scrapers 7. A protective shell 12 is provided at the bottom of the frame 1 and below the second guide roller 6 and the first guide roller 5. A cleaning mechanism 13 is provided at the bottom end inside the protective shell 12. A sterilization mechanism 14 is provided at the top end inside the protective shell 12.

[0039] Overall working principle: Before use, the frame 1 is horizontally installed below the chicken coop. The conveyor belt 3 completely covers the bottom of the chicken coop, and the protective shell 12 on the frame 1 is located at the end of the chicken coop. When in use, chicken manure falls onto the top of the conveyor belt 3. At this time, a set of scrapers 7 approaches the conveyor belt 3. The scrapers 7 are made of polytetrafluoroethylene (coefficient of friction ≤ 0.05), and the distance between the scrapers 7 and the conveyor belt 3 is 2 mm. This distance ensures the cleaning of the conveyor belt 3 without causing wear to the conveyor belt 3. At the same time, the cleaning mechanism 9 above the scraper 7 does not contact the scraper 7 and has a certain gap with the scraper 7. Another set of scrapers 7 is away from the conveyor belt 3. The top of this scraper 7 contacts the top of the cleaning mechanism 9, and the cleaning mechanism 9 is located at the top of this scraper 7. When manure cleaning is required, the drive motor 4 drives the conveyor belt 3 to rotate. The conveyor belt 3 is made of polyurethane (thickness 5 mm, tensile strength ≥ 15 MPa), and the running speed is 0.1 - 0.5 m / s. The manure is moved towards the direction of the scraper 7. The scraper 7 scrapes off the manure, and the manure moves downward along the scraper 7. When the feathers in the manure are stuck between the scraper 7 and the conveyor belt 3, the scraper 7 will be gradually squeezed, controlling the scraper 7 to move away from the conveyor belt 3. When the two sets of scrapers 7 move to the same vertical plane, the swapping mechanism 8 will be triggered at this time. The scraper 7 without stuck chicken feathers will be moved towards the conveyor belt 3, while the other set of scrapers 7 with manure and chicken feathers sticking to the surface will quickly move away from the conveyor belt 3. The sudden increase in the distance between the conveyor belt 3 and the scraper 7 will cause the stuck chicken feathers and manure to fall automatically. At the same time, when the scraper 7 moves backward quickly, the cleaning mechanism 9 scrapes off the manure on the top of the scraper 7 to ensure that the scraper 7 is cleaned once after moving away from the conveyor belt 3 for replacement use next time. In addition, during the manure cleaning process, the cleaning mechanism 13 washes and cleans the conveyor belt 3 to ensure the cleanliness of the conveyor belt 3. Finally, the sterilization mechanism 14 sterilizes the conveyor belt 3.

[0040] In this embodiment, a collection trough 10 is provided at the end of the frame 1 and below the scraper 7, and one end of the collection trough 10 is communicated with the outside of the frame 1. A spiral conveyor rod 11 is rotatably installed inside the collection trough 10 along the length direction, and the output end of the drive motor 4 is connected to the end of the spiral conveyor rod 11 through a sprocket assembly.

[0041] Local working principle: During the manure cleaning process, the manure falls into the inside of the collection trough 10. At the same time, the drive motor 4 controls the rotation of the spiral conveyor rod 11 through the sprocket assembly to push the manure towards a fixed position.

[0042] In this embodiment, guide grooves 701 are symmetrically opened on both sides of the frame 1 near one end of the first guide roller 5, and there are two sets of guide grooves 701 on both sides of the frame 1. A slider 702 is slidably arranged between the two sets of guide grooves 701 at opposite positions on both sides of the frame 1, and the slider 702 is fixed to the bottom of the scraper 7.

[0043] Local working principle: The use of the slider 702 can not only support the scraping plate 7 and stabilize the position of the scraping plate 7, but also ensure that the scraping plate 7 can slide horizontally.

[0044] In this embodiment, the swapping mechanism 8 includes a shaft rod 801, a first slide rod 802, a sliding ring 803, a push rod 804, a first sleeve 805, a pressing block 806, a first spring 807, a vertical plate 808, an arc plate 809 and a stop block 810. The shaft rod 801 is rotatably installed on both sides of the end of the frame 1. The top and bottom of the shaft rod 801 are symmetrically fixed with the first slide rods 802. The sliding rings 803 are all slidably arranged on the first slide rods 802. The push rods 804 are all hingedly installed on the sliding rings 803. The ends of the two groups of push rods 804 are respectively fixedly connected with the slider 702. A first sleeve 805 is vertically fixed on the side of the shaft rod 801 away from the first guide roller 5. The pressing block 806 is slidably installed inside the first sleeve 805. A first spring 807 is arranged between the end of the pressing block 806 and the inner end of the first sleeve 805. The vertical plates 808 are all vertically fixed on the side edges of the end of the frame 1. The arc plates 809 are all hingedly installed at the middle positions inside the vertical plates 808. The end of the pressing block 806 is attached to the inner side of the arc plate 809. The stop blocks 810 are symmetrically arranged at both ends inside the arc plate 809.

[0045] Local working principle: During the use of the device, the first slide rod 802 will always be in an inclined state, so it is ensured that only one set of scraping plates 7 is close to the conveyor belt 3, while the other set is far from the conveyor belt 3. When the first slide rod 802 is in an inclined state, the first spring 807 will exert a thrust on the pressing block 806, control the arc plate 809 to tilt to one side, and limit the position of the pressing block 806 to stabilize the inclined state of the first slide rod 802. When the first slide rod 802 is vertical, at this time the scraping plates 7 are on the same vertical plane. In this state, the first slide rod 802 is in a critical state. The end of the pressing block 806 is arc-shaped and contacts the center of the arc plate 809 at this time. The first slide rod 802 is affected by the inertia exerted by the movement of the scraping plate 7 and will rotate in the direction opposite to the initial direction. At this time, the horizontal positions of the two groups of scraping plates 7 are swapped.

[0046] In this embodiment, the cleaning mechanism 9 includes a second sleeve 901, a pressing rod 902, a second spring 903 and a scraper 904. The second sleeve 901 is vertically fixed on the side edge of the end of the frame 1 and is located above the scraping plate 7. The pressing rods 902 are all vertically slidably arranged inside the second sleeve 901. A second spring 903 is arranged between the top of the pressing rod 902 and the inner end of the second sleeve 901. A scraper 904 is fixed between the two groups of pressing rods 902 at the same horizontal plane on both sides of the end of the frame 1.

[0047] Local working principle: when the first sliding rod 802 is vertical, the scraper 7 is located on the same vertical plane, and the scraper 904 forms an angle of 30°-45° with the surface of the scraper 7, ensuring that the feces can be effectively scraped off when the scraper 7 moves. The preload force of the second spring 903 is set to 50-100N, ensuring that the scraper 904 always fits the surface of the scraper 7. The scraper 7 covered with feces and the bottom of the clean scraper 904 are in contact with the bottom of the scraper 904 respectively. As the position of the scraper 7 changes horizontally, the scraper 904 cleans the outside of the scraper 7 covered with feces, and the other group of clean scrapers 7 gradually moves away from the scraper 904 and approaches the conveyor belt 3, replacing the previous scraper 7 for feces cleaning.

[0048] In this embodiment, the cleaning mechanism 13 includes a water pipe 1301, a high-pressure nozzle 1302, a water receiving trough 1303 and a water absorption component. The water pipe 1301 is arranged at the inner bottom of the protective shell 12 along the width direction of the conveyor belt 3. The end of the water pipe 1301 is externally connected to a water pump. The side of the water pipe 1301 is evenly provided with high-pressure nozzles 1302 along the length direction, and the end of the high-pressure nozzle 1302 faces the conveyor belt 3. A water receiving trough 1303 is arranged at the bottom of the protective shell 12, and a water absorption component is arranged at the inner bottom of the protective shell 12.

[0049] Partial working principle: During the manure cleaning process, the water pump injects water into the water pipe 1301, and then the clean water is blown onto the conveyor belt 3 after rough cleaning, and the conveyor belt 3 is washed with high pressure at a water pressure of 5-10MPa (satisfying the chicken manure adhesion>0.1N / cm 2 The stripping requirement is met), each nozzle is 1-2L / min, and the total flow rate is ≥10L / min. After high-pressure flushing, the water absorption component is used to absorb the moisture on the surface of the conveyor belt 3 to avoid water pollution causing the breeding environment, and to ensure the subsequent ultraviolet sterilization effect (when the humidity is greater than 80%, the effective dose of ultraviolet attenuation decreases by about 20%).

[0050] In this embodiment, the water absorption assembly includes a fixed plate 1304, a second sliding rod 1305, a U-shaped plate 1306, a third spring 1307, a water absorption roller 1308 and a pressure roller 1309. The fixed plate 1304 is fixed to the inner bottom of the protective shell 12, and the second sliding rod 1305 is evenly slidably arranged on the fixed plate 1304. The U-shaped plate 1306 is fixed at one end of the second sliding rod 1305 close to the conveyor belt 3. The water absorption roller 1308 that fits the conveyor belt 3 is rotatably installed on the U-shaped plate 1306, and the pressure roller 1309 that squeezes the side of the water absorption roller 1308 is rotatably installed on the U-shaped plate 1306.

[0051] Local working principle: During the movement of the conveyor belt 3, the water absorption roller 1308 rolls while adhering to the surface of the conveyor belt 3. The water absorption roller 1308 is made of high-density sponge (water absorption rate ≥ 200%), which absorbs water stains. The rotation of the water absorption roller 1308 drives the pressure roller 1309 to rotate, and the pressure roller 1309 squeezes out the excess water stains inside the water absorption roller 1308. The pressure of the pressure roller 1309 is 0.2 - 0.5 MPa to ensure effective extrusion of water.

[0052] In this embodiment, the sterilization mechanism 14 includes a mounting plate 1401, an ultraviolet lamp 1402, and an atomization disinfection component. The mounting plate 1401 is fixed to the bottom of the protective shell 12, the ultraviolet lamps 1402 are evenly arranged on the top of the mounting plate 1401, and the atomization disinfection component is arranged on the inner top of the protective shell 12.

[0053] Local working principle: After cleaning the surface of the conveyor belt 3, turn on the ultraviolet lamp 1402. At a distance of 10 cm from the surface of the conveyor belt 3, ultraviolet rays are used for sterilization operations. After the conveyor belt 3 is cleaned and before hypochlorous acid atomization disinfection, the length of this section of the conveyor belt 3 is greater than or equal to 1.2 m, and the conveyor belt speed is less than or equal to 0.3 m / s. The surface intensity of the lamp tube is ≥ 30,000 μW / cm 2 , and the ultraviolet sterilization irradiation time in this section is not less than 4 s to meet the basic dose, reducing the initial bacterial count by 50%. Then, the atomization disinfection component is used for disinfection. Entrust a third-party testing agency for testing. The results show that after 4 seconds of ultraviolet irradiation, the killing rate of Escherichia coli is ≥ 99.9%.

[0054] In this embodiment, the atomization disinfection component includes a partition plate 1403, a disinfection pipe 1404, atomizing nozzles 1405, and a disinfectant supply component. The partition plate 1403 is vertically fixed to the inner bottom of the protective shell 12. The disinfection pipe 1404 is arranged parallel to the width direction of the conveyor belt 3 at the inner top of the protective shell 12. Atomizing nozzles 1405 are evenly arranged along the length direction at the top of the disinfection pipe 1404. A disinfectant supply component communicating with the inside of the disinfection pipe 1404 is arranged outside the end of the frame 1.

[0055] Local working principle: During hypochlorous acid disinfection, the hypochlorous acid is supplied by the disinfectant supply component. After the hypochlorous acid enters the inside of the disinfection pipe 1404, it is discharged from the inside of the atomizing nozzles 1405. The diameter of the mist particles is 10 - 20 μm. Due to the preliminary disinfection by ultraviolet rays, when the concentration of hypochlorous acid is 50 ppm, it can effectively perform secondary disinfection. This not only reduces costs and the risk of chemical residues, but also does not require isolation of the hens. Only ventilation of the breeding farm is needed. During operation, the wind speed in the chicken coop is maintained at 0.5 - 0.8 m / s to promote the settlement of mist particles. Entrust a third-party testing agency for testing. The results show that after hypochlorous acid atomization treatment, the killing rate of Salmonella is ≥ 99.99%.

[0056] In this embodiment, the disinfectant supply member includes a cylinder block 1406, a piston 1407, a push-pull rod 1408, a turntable 1409, a cylindrical rod 1410, a collar 1411, a disinfectant tank 1412, a liquid inlet pipe 1413 and a liquid discharge pipe 1414. The cylinder block 1406 is fixed on both sides of the end of the frame 1. A piston 1407 is slidably arranged inside the cylinder block 1406. A push-pull rod 1408 is hingedly installed on the outer side of the piston 1407. The driving motor 4 is a double-shaft motor and there are two sets of it. A turntable 1409 is fixed on one end output shaft of the driving motor 4. A cylindrical rod 1410 is vertically fixed on the outer side of the turntable 1409. A collar 1411 is sleeved on the cylindrical rod 1410. The side of the collar 1411 is fixedly connected to the push-pull rod 1408. A disinfectant tank 1412 is arranged at the bottom of the side of the frame 1. A liquid inlet pipe 1413 is arranged between the disinfectant tank 1412 and the end of the cylinder block 1406. A liquid discharge pipe 1414 is arranged between the end of the cylinder block 1406 and the disinfection pipe 1404. Check valves are arranged on both the liquid inlet pipe 1413 and the liquid discharge pipe 1414.

[0057] Local working principle: During the manure cleaning process, the double-shaft motor starts, with a rotational speed of 50 - 100 rpm, ensuring that the output flow rate of hypochlorous acid is stable at 0.5 - 1 L / min. The double-shaft motor controls the rotation of the turntable 1409. During the rotation of the turntable 1409, it reciprocally controls the piston 1407 to slide inside the cylinder block 1406 through the push-pull rod 1408. The volume of the cylinder block 1406 is 50 - 100 mL / stroke, and there are two sets of cylinder blocks 1406. The stroke of the piston 1407 is 20 - 30 mm. When one set of cylinder blocks 1406 discharges hypochlorous acid, the other set is in the extraction state. Therefore, it can ensure continuous atomization of hypochlorous acid, guarantee the sterilization effect. At the same time, adopting a mechanical transmission control method makes the control more convenient.
