Description

Technical Field

[0001] This invention relates to the field of poultry farming technology, and in particular to a deodorizing and antibacterial cage chicken house. Background Technology

[0002] To minimize the impact of external environmental changes on chicken production and maximize the artificial control of the indoor environment, large-scale chicken farms all adopt fully enclosed housing for rearing.

[0003] The current intensive cage-raising system in the chicken farming industry involves periodically cleaning manure from the horizontal ground beneath the chicken cages. To reduce chicken contact with feces, support netting is used to support the chickens. Chicken droppings pass through this netting, but as they pass through, they come into contact with it, leaving some droppings on the netting. This residual droppings then come into contact with the chickens' feet, harboring bacteria and producing foul odors, polluting the chicken coop environment and affecting the chickens' health. To reduce pathogens, regular deodorization and antibacterial treatment of the chicken cages is necessary. However, when deodorizing and antibacterializing the support netting at the bottom of the cages, directly rinsing it with pressurized water requires cleaning the entire chicken coop. All the chickens in the cages are removed, and the support netting needs to be cleaned daily. Moving the chickens back and forth is troublesome, especially with a large number of chickens. When rinsing without removing the chickens, the strong water flow startles them, causing them to jump around and making it impossible to clean the droppings from their feet. The droppings then re-adhere to the support netting, resulting in poor deodorization and antibacterial effects. When using a cleaning pad to wipe from the bottom of the support netting, the chickens' feet easily penetrate the netting, and the padting can squeeze their feet, causing them to run around unnecessarily. This makes it impossible to clean their feet. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the existing technology, rinsing causes chickens in the cage to be easily frightened during rinsing, causing them to jump around in the cage, making it impossible to clean the residual feces on their feet. The residual feces on the chicken feet then re-adhere to the support net, resulting in poor deodorization and antibacterial effect of the chicken coop cage. Therefore, this invention proposes a deodorizing and antibacterial cage chicken coop.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an odor-deodorizing and antibacterial caged chicken house, including an open box, wherein:

A scraper for scraping feces from the bottom of the open box is fixedly connected to the telescopic end of the first electric telescopic rod. A water supply mechanism is fixedly connected to the open box. A water guiding mechanism is connected to the water supply mechanism. The water guiding mechanism is connected to the scraper. A buffer box is connected to the water guiding mechanism. A narrow opening is provided at the upper end of the buffer box. There is a gap between the narrow opening and the bottom end of the support net. A tumbling mechanism is connected to the buffer box to allow cleaning water to gush out from the narrow opening.

[0010] Preferably, the water guiding mechanism includes a metal pipe, one end of which is connected to the open-type water storage tank, and the other end of which extends into the open tank. A solenoid valve is fixedly connected to the metal pipe, and a flexible hose is connected to the other end of the metal pipe. A horizontal pipe is connected to the end of the flexible hose away from the metal pipe. The horizontal pipe is fixedly connected to the upper end of the scraper. A plurality of connecting pipes are connected at equal intervals along the length of the horizontal pipe, and all of the connecting pipes are connected to the buffer tank.

[0011] Preferably, the tumbling mechanism includes a first motor, which is fixedly connected to the buffer box. The output end of the first motor is fixedly connected to a first rotating shaft. The end of the first rotating shaft away from the first motor extends into the buffer box. A circular tube is fixedly connected to the end of the first rotating shaft away from the first motor. Several arc-shaped flaps that direct water from the narrow opening are connected at equal intervals along the axis of the circular tube. The concave surface of the arc-shaped flaps faces the connecting pipe.

[0012] Preferably, the circular tube and the arc-shaped flap are an integral structure.

[0013] Preferably, the bottom end of the horizontal pipe is connected to a reversing mechanism for changing the contact direction between the flushing water and the feces at the bottom of the open box. The reversing mechanism includes a first guide plate, the upper end of which is fixedly connected to the bottom end of the horizontal pipe. The bottom end of the first guide plate is fixedly connected to an open frame for collecting flushing water. The bottom end of the open frame is connected to a plurality of drain pipes at equal intervals along the length direction. The drain pipes are inclined toward the side away from the scraper. A pressurizing component for increasing the water flow velocity on the drain pipes is connected inside the open frame. The pressurizing component is connected to the first rotating shaft.

[0014] Preferably, the pressurization assembly includes a second guide plate, which is fixedly connected to the side of the open frame near the first guide plate. An arc-shaped baffle is fixedly connected to the bottom end of the second guide plate, and the bottom end of the arc-shaped baffle contacts the inner bottom end of the open frame.

The water has a small impact on the support net, and the water will not frighten the chickens when rinsing the support net. The water will also wash the chickens' feet, removing any residual droppings. This prevents the droppings from sticking to the support net and improves its deodorizing and antibacterial effects.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1-5 A deodorizing and antibacterial caged chicken house includes an open box 1, wherein:

[0028] A chicken cage 2 is fixedly connected to the opening of an open box 1. A support net 3 is fixedly connected to the bottom of the chicken cage 2. A first electric telescopic rod 4 is connected to the open box 1. A scraper 5 for scraping feces from the bottom of the open box 1 is fixedly connected to the telescopic end of the first electric telescopic rod 4. A collection hopper 6 is connected to the bottom of the open box 1 away from the first electric telescopic rod 4. A water supply mechanism 7 is fixedly connected to the open box 1. A water guiding mechanism 8 is connected to the water supply mechanism 7. The water guiding mechanism 8 is connected to the scraper 5. A buffer box 9 is connected to the water guiding mechanism 8. A narrow opening 10 is opened at the upper end of the buffer box 9. There is a gap between the narrow opening 10 and the bottom of the support net 3. A device is connected to the buffer box 9 to allow cleaning water to flow from the narrow opening 10. The tumbling mechanism 11 is connected to a controller fixedly on the open box 1. The controller signals the first electric telescopic rod 4, the water supply mechanism 7, the water guiding mechanism 8, and the tumbling mechanism 11. When deodorizing and sterilizing the chicken cage, the controller controls the water guiding mechanism 8 to open, the water supply mechanism 7 to start, and the tumbling mechanism 11 to start. At the same time, the controller controls the first electric telescopic rod 4 to be energized and started. After the first electric telescopic rod 4 is energized and started, it drives the scraper 5 to move a set distance towards the collection hopper 6 and then reset. During the movement of the scraper 5, the scraper scrapes the manure at the bottom of the open box 1, so that the manure at the bottom of the open box 1 is pushed into the collection hopper 6. At the same time, after the water supply mechanism 7 is started, the cleaning water is continuously introduced into the water guiding mechanism 8. 8. Water is introduced into the buffer tank 9. As the water in the buffer tank 9 gradually increases, the water flows out from the narrow opening 10. When the tumbling mechanism 11 is activated, it pushes the water in the buffer tank 9. Due to the narrow width of the narrow opening 10, the water in the buffer tank 9 surges out from the narrow opening 10, forming a water column of a certain height at the upper end of the narrow opening 10. The upper end of the water column contacts the support net 3. During the movement of the scraper 5, the water guiding mechanism 8 drives the buffer tank 9 to move. There is a gap between the narrow opening 10 and the bottom end of the support net 3, so the buffer tank 9 will not touch the chicken's feet during the movement. After the buffer tank 9 moves, the water released from the narrow opening 10 affects the support net 3. The net 3 is cleaned, and the cleaning water generated falls into the open box 1. After being pushed by the scraper 5, it enters the collection hopper 6. After the tumbling mechanism 11 is activated, the water in the buffer box 9 flows out from the narrow opening 10. The water column formed by the water flowing out from the narrow opening 10 is short in height, and the water has little impact on the supporting net 3. When the chicken stands on the supporting net 3, the water flowing out will not frighten the chicken. When the water flows out to wash the supporting net 3, the chicken will not run around on the supporting net 3. At the same time, the water flows out to wash the chicken's feet and clean the residual feces on the chicken's feet. When the chicken walks on the supporting net 3, the feces on the feet will not stick to the supporting net 3, thus improving the deodorizing and antibacterial effect of the supporting net 3.

[0029] Reference Figure 3The water supply mechanism 7 includes an open-type water storage tank 71, which is fixedly connected to an open-type box 1. The open-type water storage tank 71 is a transparent water storage tank. An installation plate 72 is fixedly connected to the opening of the open-type water storage tank 71. A second electric telescopic rod 73 is fixedly connected to the upper end of the installation plate 72. The second electric telescopic rod 73 is connected to a controller via a wire. A piston plate 74 is fixedly connected to the telescopic end of the second electric telescopic rod 73. The piston plate 74 is slidably and sealingly connected to the open-type water storage tank 71. The open-type water storage tank 71 is connected to a water guiding mechanism 8 for deodorizing the chicken coop. During the antibacterial process, the controller controls the second electric telescopic rod 73 to be energized and start, driving the piston plate 74 to move downward. After the piston plate 74 moves downward, the distance between the piston plate 74 and the bottom of the open-type water storage tank 71 decreases, the space between the piston plate 74 and the bottom of the open-type water storage tank 71 decreases, the pressure in the space between the piston plate 74 and the bottom of the open-type water storage tank 71 increases, and the water in the space between the piston plate 74 and the bottom of the open-type water storage tank 71 is squeezed into the water guiding mechanism 8. As the piston plate 74 continues to move downward, it continuously squeezes water into the water guiding mechanism 8.

[0030] Reference Figure 4 The water guiding mechanism 8 includes a metal pipe 81, one end of which is connected to an open-type water storage tank 71, and the other end of which extends into the open tank 1. A solenoid valve 82 is fixedly connected to the metal pipe 81, and the solenoid valve 82 is connected to a controller via a wire. The other end of the metal pipe 81 is connected to a flexible hose 83, and the end of the flexible hose 83 away from the metal pipe 81 is connected to a horizontal pipe 84. The horizontal pipe 84 is fixedly connected to the upper end of the scraper 5, and several connecting pipes are evenly spaced along its length. All connecting pipes are connected to the buffer tank 9. When the chicken cage is deodorized and sterilized, the controller controls the solenoid valve 82 to open. The cleaning water in the open-type water storage tank 71 is introduced into the hose 83 through the metal pipe 81. The hose 83 introduces the water into the horizontal pipe 84. The water in the horizontal pipe 84 is introduced into the buffer tank 9 through the connecting pipe. After the chicken cage is deodorized and sterilized, the controller controls the solenoid valve 82 to close, so as to prevent the water in the buffer tank 9 from communicating with the water in the open-type water storage tank 71, thereby preventing feces from entering the open-type water storage tank 71.

[0031] Reference Figure 5The tumbling mechanism 11 includes a first motor 111, which is fixedly connected to the buffer tank 9. The first motor 111 is connected to a controller via a wire. The output end of the first motor 111 is fixedly connected to a first rotating shaft 112. One end of the first rotating shaft 112 away from the first motor 111 extends into the buffer tank 9. A circular tube 113 is fixedly connected to the other end of the first rotating shaft 112 away from the first motor 111. Several arc-shaped flaps 114, which direct water to gush out from the narrow opening 10, are evenly connected along the axis of the circular tube 113. Facing the direction of the connecting pipe, the round pipe 113 and the arc-shaped flap 114 are an integral structure. When the controller controls the first motor 111 to be powered on and started when deodorizing and sterilizing the chicken cage, the first motor 111 drives the first rotating shaft 112 to rotate. The first rotating shaft 112 drives the arc-shaped flap 114 to rotate. After the arc-shaped flap 114 rotates, it pushes the water in the buffer tank 9 upward, so that the water in the buffer tank 9 flows out from the narrow opening 10 and forms a water column of a certain height on the narrow opening 10. The water column formed has a small impact on the support net 3 and will not frighten the chickens.

[0032] Example 2

[0033] When a water column of a certain height is released at the narrow opening 10 to clean, deodorize, and inhibit bacteria on the support net 3, the cleaning water generated during rinsing falls downwards under its own gravity. The cleaning water vertically impacts the bottom of the open box 1, colliding with the manure on the bottom of the open box 1. After being impacted by the water, the manure is dispersed, increasing the contact area between the manure and the air. The water containing the manure splashes onto the inner wall of the open box 1, releasing odors. The dispersed manure releases a significant amount of odor, which is released into the chicken house, reducing the air quality inside the chicken house. At the same time, when the scraper 5 scrapes the manure at the bottom of the open box 1, some manure adheres to the scraper 5, reducing the scraping effect of the scraper 5 on the manure at the bottom of the open box 1. (Refer to...) Figure 6-7As another preferred embodiment of the present invention, based on embodiment 1, the bottom end of the horizontal pipe 84 is connected to a reversing mechanism 12 for changing the contact direction between the flushing water and the feces at the bottom of the open box 1. The reversing mechanism 12 includes a first guide plate 121, the upper end of which is fixedly connected to the bottom end of the horizontal pipe 84, and the bottom end of the first guide plate 121 is fixedly connected to an open frame 122 for collecting flushing water. The bottom end of the open frame 122 is connected to a plurality of drain pipes 127 at equal intervals along the length direction, and the drain pipes 127 are directed away from the scraper. The plate 5 is tilted on one side. A pressurizing component for increasing the water flow velocity on the drain pipe 127 is connected inside the open frame 122. The pressurizing component is connected to the first rotating shaft 112. After the cleaning water released from the narrow opening 10 washes the support net 3, part of the cleaning water falls directly into the open frame 122 along the outer wall of the buffer box 9, and the other part falls onto the first guide plate 121. The first guide plate 121 guides the cleaning water into the open frame 122, where it is collected. The cleaning water will not fall vertically into the open box. The bottom of the inner part of the container 1 will not collide with the feces on the bottom of the open container 1, thus reducing the contact area between the feces and the air and reducing the generation of odor. After the first rotating shaft 112 rotates, it drives the pressurizing component to rotate. After the pressurizing component rotates, it squeezes the cleaning water in the open frame 122, thereby accelerating the discharge speed of the cleaning water from the drain pipe 127. The drain pipe 127 is set at an angle, and the cleaning water released from the drain pipe 127 washes the feces on the bottom of the open container 1 from the side. The washing position is where the feces and the bottom of the open container 1 are washed. The adhesive joint at the end allows the feces adhering to the bottom of the open box 1 to separate from the open box 1. After separating the feces from the open box 1, the contact area between the feces and the air will not increase. When the scraper 5 scrapes the feces at the bottom of the open box 1, the cleaning water released from the drain pipe 127 has already rinsed the bottom of the open box 1. Thus, the scraper 5 pushes the cleaning water remaining at the bottom of the open box 1, and the cleaning water enters the collection hopper 6. As a result, no feces will adhere to the scraper 5, thus improving the scraping effect of the scraper 5.

[0034] Reference Figure 6 and 7The pressurization assembly includes a second guide plate 123. The second guide plate 123 is fixedly connected to the side of the open frame 122 near the first guide plate 121. An arc-shaped baffle 124 is fixedly connected to the bottom end of the second guide plate 123, and the bottom end of the arc-shaped baffle 124 contacts the inner bottom end of the open frame 122. A second rotating shaft 125 is rotatably connected to the open frame 122. A compression plate 126 is fixedly connected to the second rotating shaft 125, and the compression plate 126 cooperates with the arc-shaped baffle 124. A first sealing chamber is formed inside the open frame 122, and a second sealing chamber is formed inside the buffer box 9. A hollow frame 128 connects the first and second sealing chambers. The second rotating shaft 125 extends into the first sealing chamber and is connected to the first rotating shaft 112 via a belt drive 129 located in the hollow frame. Inside the frame 128, the cleaning water introduced from the first guide plate 121 falls onto the second guide plate 123 and is released from the bottom end of the second guide plate 123. The first rotating shaft 112 rotates through the belt drive 129, which drives the second rotating shaft 125 to rotate. The second rotating shaft 125 drives the squeezing plate 126 to rotate. The rotating squeezing plate 126 draws in the cleaning water released from the bottom end of the second guide plate 123. The drawn-in cleaning water enters the arc-shaped baffle 124 and is released from the bottom end of the arc-shaped baffle 124. The released cleaning water impacts the cleaning water inside the open frame 122, thereby accelerating the release of cleaning water on the drain pipe 127. The accelerated cleaning water washes away the feces adhering to the open box 1, causing the feces adhering to the bottom end of the open box 1 to separate from the open box 1, and no feces will adhere to the scraper 5.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
