Description

Technical Field

[0001] This invention relates to the field of pig farming, and in particular to a disinfection and cleaning device and method for pig farms. Background Technology

[0002] Currently, disinfection and cleaning operations in pigsties are generally carried out manually. This usually involves manual high-pressure spray guns used by workers to wash and disinfect the walls and floors of the pigsties. The floors of the pigsties are mostly made of slatted flooring, and the wastewater generated from washing and disinfection flows into the manure and urine ditch through the slatted flooring and is discharged away.

[0003] Maintaining a clean and hygienic pigsty environment is crucial for ensuring the health of pigs. However, the lower surface of the slatted floor and the walls of the manure and urine drains beneath it often remain uncleaned, leaving behind a large amount of pig urine and feces. When temperatures are high, these residual substances can easily breed viruses and bacteria, polluting the air in the pigsty and severely impacting the pigs' living environment and disease control. Manually removing the slatted floor and cleaning and disinfecting the lower surface and manure and urine drains is extremely troublesome, time-consuming, labor-intensive, and costly. Summary of the Invention

[0004] The main objective of this invention is to provide a disinfection and cleaning device and method for pig farms, aiming to solve the problem that there are dead corners in cleaning and disinfection in current pig houses, and that the lower surface of slatted floors and the walls of manure and urine ditches cannot be cleaned and disinfected.

[0005] To address the aforementioned problems, this invention proposes a disinfection and cleaning device for pig farms, used for cleaning and disinfecting pig house units. The disinfection and cleaning device includes a scrubbing drum penetrating the pig house unit and linear motors located at both ends of the scrubbing drum. The linear motors and the scrubbing drum are both horizontally arranged and perpendicular to each other. The linear motors are mounted on a lifting device, and the lifting device and the linear motor drive the scrubbing drum to move in the vertical plane containing the cross-section of the pig house unit.

[0006] The scrubbing cylinder includes a cylinder body and water spray holes and brush bristles provided on the outer circumferential surface of the cylinder body. One end of the cylinder body is open and the other end is sealed. The open end of the cylinder body is in rotary sealing communication with the infusion tube.

[0007] The cylinder is connected to the drive motor, which drives the cylinder to rotate. The drive motor is mounted on a linear motor.

[0008] In one embodiment, the infusion tube is a flexible tube, and a reversing valve is connected to the infusion tube. The reversing valve is connected to inlet tube one and inlet tube two.

[0009] In one embodiment, there are multiple pig house units, and the brush rollers in the multiple pig house units are arranged in parallel and spaced apart, and are synchronously connected by a transmission belt and a drive motor.

[0010] In one embodiment, the pigsty unit includes:

[0011] A pair of parallel vertical plates are arranged at intervals, and the lower ends of the pair of vertical plates are fixedly connected to a horizontally arranged base plate.

[0012] A pair of parallel vertical plates are located between a pair of vertical plates and are parallel to the pair of vertical plates. The lower end of the vertical plates is fixedly connected to a horizontally arranged base plate, thereby forming a pig urine trough between the vertical plates and the vertical plates on the base plate, and forming a pig manure trough between the pair of vertical plates on the base plate.

[0013] The filter screen is set at an angle on the upright plate and is located directly above the pig urine trough. After pig manure falls onto the filter screen, it rolls down the filter screen into the pig manure trough. After pig urine falls onto the filter screen, it passes through the filter screen and falls into the pig urine trough.

[0014] A flow deflector, located above a pair of filters and directly above the pig manure trough, is used to prevent pig manure and urine from falling vertically through the gap between the filters.

[0015] The slatted floor is horizontally fixed to the upper end of a pair of vertical panels. The flow guide is fixedly installed on the lower surface of the slatted floor. Pig manure and urine that penetrate the slatted floor fall onto the flow guide or filter screen. The pig manure and urine on the flow guide roll down the flow guide and onto the filter screen.

[0016] In one embodiment, side baffles are vertically fixed at both ends of the slatted floor along the axial direction of the scrubbing cylinder. The side baffles are perpendicular to the axial direction of the scrubbing cylinder and enclose an area for pigs to move around on the slatted floor.

[0017] In one embodiment, a walkway is horizontally arranged on the side of the side baffle away from the slatted floor. Below the walkway, a vertical plate is arranged at a distance from the vertical plate and parallel to the side baffle. Two vertical plates are vertically fixed at both ends of the bottom surface along the axial direction of the scrubbing cylinder. The vertical plates are spaced apart and parallel to each other, thereby defining a fecal and urine ditch between the vertical plates and between the vertical plates.

[0018] The bottom surface of the pig urine trough is provided with a through hole, the width of which is equal to the width of the pig urine trough. The pig urine in the pig urine trough falls through the through hole into the manure ditch between the two vertical plates. The pig manure in the pig manure trough moves to the end of the pig manure trough and falls into the manure ditch between the vertical plates.

[0019] In one embodiment, the linear motor, lifting device, and infusion tube are located between the vertical plate and the upright plate.

[0020] In one embodiment, a mounting rod is fixedly installed on the lower surface of the filter screen near one end of the upright plate;

[0021] The sides of the first and second upright plates are provided with chamfered strips at the ends near the bottom plate;

[0022] The upper end of the flow guide is fixedly connected to the lower surface of the slatted floor via a vertical plate.

[0023] In one embodiment, the scrubbing drum is rotatably mounted on a shaft bracket, which is fixedly connected to a linear motor.

[0024] Furthermore, this invention also proposes a disinfection and cleaning method for pig farms, which involves performing the following steps using any of the aforementioned disinfection and cleaning devices for pig farms:

[0025] S1. Cleaning fluid is introduced into the cylinder through the infusion tube, and the cleaning fluid is sprayed out through the spray hole;

[0026] S2. Start the drive motor to make the brush drum rotate;

[0027] S3. Control the lifting device and linear motor to drive the brushing cylinder to move radially on the vertical plane where the cross-section of the pig house unit is located, so that the cleaning liquid sprayed through the spray holes is directed towards the lower surface of the slatted floor, the outer surface of the guide hood, the inner side of the first upright plate, the outer surface of the filter screen, and the outer surface of the second upright plate, and the brush bristles brush the lower surface of the slatted floor, the outer surface of the guide hood, the inner side of the first upright plate, the outer surface of the filter screen, and the outer surface of the second upright plate.

[0028] S4. Replace the cleaning solution with disinfectant, and then repeat S1-S3.

[0029] Beneficial effects: The disinfection and cleaning device of this application can thoroughly clean and disinfect the pig house unit of this application, including the cleaning and disinfection of the lower surface of the slatted floor and the walls of the manure and urine ditch, eliminating dead corners in the cleaning of the pig house, ensuring that the pig house is clean and hygienic, without the need for manual removal of the slatted floor, saving time and effort, and reducing labor costs.

[0030] The pigsty unit of this application can realize the real-time separation of pig manure and pig urine, reducing the generation of harmful gases such as ammonia and hydrogen sulfide in the pigsty and lowering the treatment cost of pig manure and urine. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] This invention proposes a pig farm, such as Figure 1 As shown, the pig farm includes several parallel pig house units 1. Each pig house unit 1 includes: a floor 110, a pair of parallel vertical plates 11 spaced apart, a pair of parallel vertical plates 2 12 spaced apart, a filter screen 15, a flow guide hood 16, and a slatted floor 18. The lower ends of the pair of parallel vertical plates 11 are fixedly connected to the horizontally arranged floor 110. The pair of parallel vertical plates 2 12 are located between the pair of parallel vertical plates 11 and are parallel to the pair of parallel vertical plates 11. The lower ends of the pair of parallel vertical plates 2 12 are fixedly connected to the horizontally arranged floor 110, thereby forming a pig urine trough 10 between the pair of parallel vertical plates 2 12 and the pair of parallel vertical plates 11 on the floor 110, and forming a pig manure trough 19 between the pair of parallel vertical plates 2 12 on the floor 110. The floor 110 can effectively prevent pig manure and urine from seeping into the ground.

[0046] In this embodiment, as Figure 1 As shown, the filter screen 15 is inclinedly set on the upright plate 11 and located directly above the pig urine trough 10. After pig manure falls onto the filter screen 15, it rolls down along the filter screen 15 to the pig manure trough 19. After pig urine falls onto the filter screen 15, it passes through the filter screen 15 and falls into the pig urine trough 10. This allows for real-time separation of pig manure and urine, preventing them from mixing together and causing more secondary pollution. It also reduces the generation of harmful gases such as ammonia and hydrogen sulfide in the pigsty, protects the health of the pigs, and reduces the treatment cost of pig manure and urine without diminishing their inherent value.

[0047] In this embodiment, as Figure 1As shown, the flow guide 16 is located above a pair of filter screens 15 and directly above the pig manure trough 19. It prevents pig manure and urine from falling vertically through the filter screens 15, causing them to mix and fall into the pig manure trough 19. The slatted floor 18 is horizontally fixed to the upper end of a pair of vertical plates 11. The flow guide 16 is fixedly installed on the lower surface of the slatted floor 18. Pig manure and urine penetrating the slatted floor 18 fall onto the flow guide 16 or the filter screens 15. Pig manure and urine roll down the guide hood 16 onto the filter screen 15. After falling onto the filter screen 15, the pig manure rolls down the filter screen 15 into the pig manure trough 19, while the pig urine falls onto the filter screen 15 and then passes through the filter screen 15 into the pig urine trough 10. This process separates pig manure and urine in real time, preventing them from mixing and causing more secondary pollution. It also reduces the generation of harmful gases such as ammonia and hydrogen sulfide in the pigsty, protecting the health of the pigs and lowering the cost of treating pig manure and urine without diminishing their inherent value.

[0048] In this embodiment, as Figure 1 As shown, the pig farm also includes side baffles 2. Side baffles 2 are vertically fixed at both ends of the slatted floor 18 along the axial direction of the scrubbing cylinder 7. The side baffles 2 are perpendicular to the axial direction of the scrubbing cylinder 7. The side baffles 2 enclose an area for pigs to move around on the slatted floor 18.

[0049] Furthermore, such as Figure 1 As shown, a walkway 3 is horizontally arranged on the side of the side baffle 2 away from the slatted floor 18. The walkway 3 provides space for people to walk on. Below the walkway 3, a vertical plate 17 is spaced apart from the vertical plate 11 and parallel to the side baffle 2. Two vertical plates 17 are vertically fixed at both ends of the bottom surface of the base plate 110 along the axial direction of the scrubbing cylinder 7. The vertical plates 17 and 17 are spaced apart and parallel to each other, thus defining a manure / urine ditch 6 between the vertical plates 17 and 17 and between the two vertical plates 17. The bottom surface of the pig urination trough 10... A through hole 111 is provided, the width of which is equal to the width of the pig urine trough 10, to ensure that all the pig urine in the pig urine trough 10 falls through the through hole 111 into the manure ditch 6 between the two vertical plates 17. The pig manure in the pig manure trough 19 moves to the end of the pig manure trough 19 under the action of the manure scraper or water flow and falls into the manure ditch 6 between the vertical plates 17 and 17. Finally, the pig manure and pig urine flow away along the manure ditch 6 respectively, and the pig manure and pig urine do not mix together throughout the process.

[0050] The pigsty unit 1 in this embodiment can realize the real-time separation of pig manure and pig urine, avoiding the mixing of pig manure and pig urine and generating more secondary pollution, reducing the generation of harmful gases such as ammonia and hydrogen sulfide in the pigsty, protecting the health of pigs, and reducing the treatment cost of pig manure and pig urine without reducing the inherent value of pig manure and pig urine.

[0051] Furthermore, this invention also proposes a disinfection and cleaning device for pig farms, used to clean and disinfect each pig house unit 1 of the aforementioned pig farm. The disinfection and cleaning device of this invention can thoroughly clean and disinfect the pig house unit 1 of this application, including cleaning and disinfecting the lower surface of the slatted floor 18 and the walls of the manure and urine ditch 6. It eliminates the need for manual removal of the slatted floor 18 to clean and disinfect the lower surface of the slatted floor 18 and the walls of the manure and urine ditch 6, thus eliminating dead corners in pig house cleaning and ensuring that the pig house is clean and hygienic.

[0052] Specifically, in this embodiment, such as Figure 2 As shown, the disinfection and cleaning device includes a scrubbing drum 7 that runs through the pigsty unit 1 and linear motors 81 located at both ends of the scrubbing drum 7. The linear motors 81 and the scrubbing drum 7 are both horizontally arranged and perpendicular to each other. The linear motors 81 are mounted on the lifting device 82. With this design, the scrubbing drum 7 can be driven to move radially in the vertical plane where the cross-section of the pigsty unit 1 is located by the lifting device 82 and the linear motor 81 to achieve all-round, no-dead-angle cleaning and disinfection of the pigsty unit 1. This includes cleaning and disinfecting the lower surface of the slatted floor 18, the outer surface of the guide hood 16, the inner side of the first upright plate 11, the outer surface of the filter screen 15, and the outer surface of the second upright plate 12.

[0053] In this embodiment, as Figure 3 As shown, the scrubbing cylinder 7 includes a cylinder body 71 and spray holes 73 and brush bristles 72 disposed on the outer circumferential surface of the cylinder body 71. The spray holes 73 and brush bristles 72 are arranged in a ring array on the outer circumferential surface of the cylinder body 71. One end of the cylinder body 71 is open and the other end is sealed. The open end of the cylinder body 71 is rotatably and sealedly connected to the infusion tube 85. This design does not affect the injection of cleaning solution and disinfectant into the cylinder body 71 through the infusion tube 85, nor does it affect the rotation of the cylinder body 71. The cleaning solution and disinfectant injected into the cylinder body 71 are sprayed out from the spray holes 73 and directed towards... The lower surface of the slatted floor 18, the outer surface of the flow guide hood 16, the inner side of the first upright plate 11, the outer surface of the filter screen 15, and the outer surface of the second upright plate 12 are cleaned and disinfected. At the same time, the cylinder 71 rotates and drives the brush 72 to scrub the lower surface of the slatted floor 18, the outer surface of the flow guide hood 16, the inner side of the first upright plate 11, the outer surface of the filter screen 15, and the outer surface of the second upright plate 12, completing the all-round, no dead corner cleaning and disinfection of the pig house unit 1, including the cleaning and disinfection of the lower surface of the slatted floor 18 and the walls of the manure and urine ditch 6, eliminating dead corners in the pig house cleaning and ensuring that the pig house is clean and hygienic.

[0054] In this embodiment, as Figure 2 As shown, the cylinder 71 is connected to the drive motor 83, which drives the cylinder 71 to rotate. The drive motor 83 is mounted on the linear motor 81. When there are multiple pigsty units 1, such as... Figure 2 As shown, the brushing drums 7 in multiple pigsty units 1 are arranged in parallel at intervals and are synchronously connected by a transmission belt 84 and a drive motor 83.

[0055] In this embodiment, as Figure 2 As shown, the infusion tube 85 is a flexible tube. This design avoids the infusion tube 85 affecting the radial movement of the cylinder 71. A reversing valve 86 is connected to the infusion tube 85. The reversing valve 86 is connected to the first infusion tube 87 and the second infusion tube 88. The first infusion tube 87 is used to deliver cleaning solution into the infusion tube 85, and the second infusion tube 88 is used to deliver disinfectant into the infusion tube 85.

[0056] In this embodiment, the linear motor 81, the lifting device 82, and the infusion pipe 85 are located between the vertical plate 17 and the upright plate 11. This design allows the disinfection and cleaning device of this embodiment to be perfectly matched with the pig farm of the aforementioned embodiment, so that the disinfection and cleaning device of the present invention can be specifically used for cleaning and disinfecting each pig house unit 1 of the aforementioned pig farm.

[0057] In this embodiment, to facilitate the connection between the cylinder 71 and the linear motor 81, as follows: Figure 2 As shown, the scrubbing drum 7 is rotatably mounted on the shaft frame 8, and the shaft frame 8 is fixedly connected to the linear motor 81.

[0058] In this embodiment, further, such as Figures 1-3 As shown, an installation rod 14 is fixedly installed on the lower surface of the filter screen 15 near the end of the upright plate 11. The installation rod 14 can enhance the connection between the filter screen 15 and the upright plate 11, and at the same time facilitate the brush filaments 72 to clean. Without the installation rod 14, pig manure and urine splash into the narrow space where the installation rod 14 is located, making it difficult for the brush filaments 72 to clean this narrow space, and dead corners that cannot be cleaned are easily formed. After the installation rod 14 is filled into the narrow space, it is not only convenient to clean and eliminates dead corners, but also enhances the connection between the filter screen 15 and the upright plate 11, achieving two goals at once.

[0059] In this embodiment, further, such as Figures 1-3As shown, chamfered strips 13 are provided on the side of the first upright plate 11 and the second upright plate 12 near the bottom plate 110. The design of the chamfered strips 13 can enhance the connection between the first upright plate 11 and the second upright plate 12 and the bottom plate 110, and also avoid the formation of blind corners for cleaning. The chamfered strips 13 are filled in the narrow corners of the side of the first upright plate 11 and the second upright plate 12 near the bottom plate 110, which can facilitate cleaning, eliminate blind corners for cleaning, and enhance the connection between the first upright plate 11 and the second upright plate 12 and the bottom plate 110, achieving two goals at once.

[0060] In this embodiment, further, such as Figures 1-3 As shown, the upper end of the flow guide shroud 16 is fixedly connected to the lower surface of the slatted floor 18 via a vertical plate 17. This design facilitates the brush bristles 72 to clean the upper end of the flow guide shroud 16. Without the vertical plate 17, the upper end of the flow guide shroud 16 and the lower surface of the slatted floor 18 form a narrow wedge-shaped space, which is not easy to be cleaned by the brush bristles 72 and may result in dead corners that cannot be cleaned.

[0061] Furthermore, this invention also proposes a disinfection and cleaning method for pig farms, which involves performing the following steps using any of the aforementioned disinfection and cleaning devices for pig farms:

[0062] S1. Cleaning fluid is introduced into the cylinder 71 through the infusion pipe 85, and the cleaning fluid is sprayed out through the water spray hole 73.

[0063] S2. Start the drive motor 83 to drive the brush drum 7 to rotate;

[0064] S3. The control lifting device 82 and linear motor 81 drive the brushing cylinder 7 to move radially in the vertical plane where the cross-section of the pig house unit 1 is located. This causes the cleaning liquid sprayed through the spray holes 73 to be directed towards the lower surface of the slatted floor 18, the outer surface of the guide hood 16, the inner side of the first upright plate 11, the outer surface of the filter screen 15, and the outer surface of the second upright plate 12. The brush bristles 72 then brush the lower surface of the slatted floor 18, the outer surface of the guide hood 16, the inner side of the first upright plate 11, the outer surface of the filter screen 15, and the outer surface of the second upright plate 12. The cleaning path 9 of the brushing cylinder 7 moving radially in the vertical plane where the cross-section of the pig house unit 1 is located is as follows: Figure 3 As shown by the middle arrow, when the scrubbing cylinder 7 is not working, it is located at point a below the guide shroud 16. Storing the scrubbing cylinder 7 here can prevent pig manure and urine from falling onto the scrubbing cylinder 7, thus keeping the scrubbing cylinder 7 clean and tidy.

[0065] S4. After cleaning pigsty unit 1 is completed, control the reversing valve 86 to switch the cleaning solution to disinfectant. Then repeat S1-S3 to disinfect pigsty unit 1.

[0066] This embodiment of a pig farm disinfection and cleaning method utilizes any of the aforementioned pig farm disinfection and cleaning devices to simultaneously perform comprehensive, thorough cleaning of multiple pigsty units 1. Figure 3 The cleaning route 9 shown cleans pigsty unit 1, which can thoroughly clean and disinfect the lower surface of the slatted floor 18, the outer surface of the guide hood 16, the inner side of the first upright 11, the outer surface of the filter screen 15, and the outer surface of the second upright 12, effectively ensuring the cleanliness and hygiene of pigsty unit 1 and preventing the accumulation of pig manure and urine on the lower surface of the slatted floor 18 and the walls of the manure and urine ditch 6, thus avoiding pollution of the pigsty environment.

[0067] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
