Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and specifically discloses a multi-directional ventilation livestock shed for animal husbandry. Background Technology

[0002] In the livestock farming sector, the environment of livestock sheds directly affects the health and growth of livestock and the profitability of farming. As a core element of livestock shed environmental control, the performance of the ventilation system is crucial. Traditional livestock sheds mostly rely on side vents for air circulation, which has significant limitations in terms of ventilation range and efficiency. Airflow within the shed is difficult to distribute evenly, resulting in stale and polluted air in some areas, creating ventilation dead zones. This not only reduces the overall ventilation effect but also fails to ensure sufficient air renewal within the shed.

[0003] The Chinese patent application CN222465646U discloses a multi-directional ventilation livestock shed for animal husbandry, relating to the field of animal husbandry technology. The shed includes a transmission mechanism on its top, comprising a motor with a drive gear fixedly connected to its output shaft. The drive gear is rotatably connected to a transmission gear, and a rotating rod is fixedly connected to the center of the transmission gear. Both ends of the rotating rod are fixedly connected to first bevel gears, and the inclined gear teeth of the first bevel gears are rotatably connected to second bevel gears. Multiple ventilation windows are installed around the shed's perimeter, facilitating multi-directional ventilation. The transmission mechanism moves the sealed top, ensuring ventilation and exchanging of air within the shed, removing stale air, preventing poor air circulation that could affect livestock operations, and ensuring sufficient fresh air supply necessary for the animals' life activities.

[0004] The aforementioned device has made some innovative designs for livestock shed ventilation, but it still has many limitations. The livestock shed ventilation system involved in this patent has a relatively simple ventilation mode, and its ventilation path and method are relatively fixed. In cold weather conditions, directly introducing cold air will cause cold stress in livestock and poultry. Although the device can close some air inlets to keep warm when the ventilation pipe is in use, it will result in insufficient air exchange and will also cause harmful gases such as ammonia produced by livestock manure to not be discharged in time, further deteriorating air quality and endangering the respiratory health of livestock. Utility Model Content

[0005] This utility model proposes a multi-directional ventilation livestock shed for animal husbandry. By ensuring that every corner of the shed is adequately ventilated, the air quality inside the shed is effectively improved, providing a healthier breathing environment for livestock. During ventilation, the shed maintains a suitable temperature environment for livestock growth, effectively preventing excessive temperature drops and ensuring a warm and comfortable environment. Furthermore, the ventilation process improves the air quality inside the shed and enhances the surrounding environment of the farm.

[0006] This utility model is implemented as follows: a livestock shed with multi-directional ventilation for animal husbandry includes a shed body, a door panel at the front end of the shed body, and a pen inside the shed body. The shed body has an internal ventilation mechanism. The ventilation mechanism includes two ventilation pipes fixedly installed between the front and rear end faces inside the shed body. Multiple evenly distributed air outlets are opened at the bottom of the ventilation pipes. Connecting pipes are connected to both ends of the ventilation pipes. The other end of each connecting pipe penetrates the inner wall of the shed body and connects to a first air inlet pipe. A first fan is installed inside the first air inlet pipe. Second air inlet pipes in an inverted "L" shape are provided on both the left and right sides of the shed body. One end of each second air inlet pipe penetrates the outer wall of the shed body and connects to the ventilation pipes. A hot air fan is installed inside each second air inlet pipe. Ventilation ports are opened at the bottom of both the left and right sides inside the shed body. The top surface of each ventilation port is rotatably connected to an openable and closable ventilation window via a rotating shaft.

[0007] The exterior of the building is equipped with an odor removal mechanism.

[0008] As a preferred embodiment of the present invention, a multi-directional ventilation livestock shed for livestock breeding includes a manure collection tank fixedly installed at the bottom of the shed and embedded in the ground. The top of the manure collection tank is open. Filter boxes connected to the manure collection tank through pipes are provided on both the left and right sides of the shed. The filter boxes are equipped with pull-out activated carbon filter plates. An air outlet pipe is connected to the side of the filter box away from the shed. A second fan is provided inside the filter box on the side of the activated carbon filter plate near the air outlet pipe.

[0009] The bottom of the enclosure has multiple manure discharge holes located below the enclosure.

[0010] As a preferred embodiment of the multi-directional ventilation livestock shed of this utility model, an electric actuator is movably installed between the bottom of the inner wall of the ventilation port and the outer wall of the ventilation window via a rotating shaft.

[0015] The beneficial effects of this utility model are:

[0016] 1. Through the first fan, the first air inlet pipe, the connecting pipe, and the ventilation pipe, airflow is discharged from multiple air outlets to form a "vertical airflow curtain". The opening and closing angle of the ventilation window can be adjusted by the electric actuator. The airflow inside the shed can be discharged through the ventilation port to achieve uniform air supply from top to bottom. This avoids the ventilation dead corners caused by traditional side air supply, so that every corner of the shed can be fully ventilated, ensuring that fresh air is evenly distributed, effectively improving the air quality inside the shed, and providing a healthier breathing environment for livestock.

[0017] 2. Through the hot air blower, the second air inlet pipe and the ventilation pipe, warm air is sent out from multiple air outlets, which can ensure that the temperature environment in the livestock shed is always suitable for the growth of livestock, effectively avoid excessive temperature drop, and ensure that the shed is warm and comfortable.

[0018] 3. During the ventilation process, the manure collection tank collects the manure, and the second fan forces the exhaust air in, allowing the airflow to enter the filter box. The activated carbon filter plate absorbs the odor, thus playing a role in ventilation and deodorization, improving the air quality inside the shed and improving the surrounding environment of the farm.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-4 A livestock shed with multi-directional ventilation for livestock farming includes a shed body 1, a door panel 101 located at the front end of the shed body 1, and a pen 102 located inside the shed body 1. The shed body 1 is equipped with a ventilation mechanism. The ventilation mechanism includes two ventilation pipes 2 fixedly installed between the front and rear end faces inside the shed body 1. The bottom of the ventilation pipes 2 has multiple evenly distributed air outlets 201. The two ends of the ventilation pipes 2 are respectively connected to connecting pipes 302. The other end of the connecting pipes 302 penetrates the inner side wall of the shed body 1 and is connected to a first air inlet pipe 3. A first fan 301 is installed inside the first air inlet pipe 3. The left and right sides of the shed body 1 are each equipped with a second air inlet pipe 4 in the shape of an inverted "L". One end of the second air inlet pipe 4 penetrates the outer side wall of the shed body 1 and is connected to the ventilation pipe 2. A hot air fan 401 is installed inside the second air inlet pipe 4. Ventilation ports 5 are opened at the bottom of the left and right sides inside the shed body 1. The top surface inside the ventilation port 5 is rotatably connected to an openable and closable ventilation window 501 via a rotating shaft.

[0027] A deodorization mechanism is installed on the outside of the housing 1.

[0028] In this embodiment: When ventilation is performed, the first fan 301 is started, so that fresh air from the outside enters the ventilation pipe 2 through the first air inlet pipe 3 and the connecting pipe 302, and is discharged from multiple air outlets 201 at the bottom of the ventilation pipe 2 to form a "vertical airflow curtain". The electric actuator 502 is started, which can push the ventilation window 501 to rotate and open the ventilation window 501. The airflow in the shed 1 can be discharged through the ventilation port 5, realizing uniform air supply from top to bottom, avoiding the ventilation dead corners caused by traditional side air supply, so that every corner of the shed can be fully ventilated, ensuring that fresh air is evenly distributed, effectively improving the air quality in the shed, and providing a healthier breathing environment for livestock.

[0029] Furthermore, during the ventilation process, when the temperature inside the shed 1 is lower than the set value, the hot air blower 401 is activated. The cold air is heated through the second air inlet pipe 4 and enters the ventilation pipe 2. The warm air is sent out from multiple air outlets 201, which can ensure that the temperature environment inside the livestock shed is always suitable for the growth of livestock, effectively avoid excessive temperature drop, and ensure that the shed is warm and comfortable.

[0030] During ventilation, the manure falls into the manure collection tank 6 through the manure drop hole 601. The second fan 702 is activated to force ventilation, allowing the airflow to enter the filter box 7. The activated carbon filter plate 701 absorbs the odor, thus playing a role in ventilation and deodorization, improving the air quality inside the shed and improving the surrounding environment of the farm.

[0031] As a technical optimization of this utility model, the deodorization mechanism includes a manure collection tank 6 fixedly installed at the bottom of the housing 1 and embedded in the ground. The top of the manure collection tank 6 is open. Filter boxes 7 are provided on both the left and right sides of the housing 1 and are connected to the manure collection tank 6 through pipes. The filter box 7 is provided with a pull-out activated carbon filter plate 701. The side of the filter box 7 away from the housing 1 is connected to an air outlet pipe. A second fan 702 is provided inside the filter box 7 on the side of the activated carbon filter plate 701 close to the air outlet pipe.

[0032] The bottom of the enclosure 1 has multiple manure holes 601 located below the enclosure 102.

[0033] In this embodiment: the manure of the livestock raised in the pen 102 can fall into the manure collection tank 6 through the manure drop hole 601. When the second fan 702 is started, the airflow in the pen 1 can enter the manure collection tank 6 through the manure drop hole 601 and enter the filter box 7 through the pipe. The odor in the airflow is adsorbed and deodorized by the activated carbon filter plate 701 and then discharged from the air outlet pipe.

[0034] As a technical optimization of this utility model, an electric actuator 502 is movably installed between the bottom of the inner wall of the ventilation port 5 and the outer wall of the ventilation window 501 via a rotating shaft.

[0035] In this embodiment: by activating the electric actuator 502, the movable ventilation window 501 can be rotated, the size of the ventilation port 5 can be adjusted, and the opening and closing of the ventilation window 501 can be controlled.

[0036] As a technical optimization of this utility model, a first one-way valve 303 is provided inside the connecting pipe 302; a second one-way valve 402 is provided on the side of the hot air blower 401 near the ventilation pipe 2, and the number of the second air inlet pipe 4 and the ventilation port 5 is at least two.

[0037] In this embodiment: the first one-way valve 303 can ensure that the airflow enters the ventilation pipe 2 and prevent the airflow in the ventilation pipe 2 from flowing back into the first air inlet pipe 3. The second one-way valve 402 can prevent the airflow in the ventilation pipe 2 from entering the second air inlet pipe 4. The number of the second air inlet pipe 4 and the ventilation port 5 can be set according to the area of ​​the body 1.

[0038] As a technical optimization of this utility model, bird netting is fixedly installed inside the ventilation pipe 2, the first air inlet pipe 3, the second air inlet pipe 4, the air outlet pipe, and the ventilation port 5.

[0039] In this embodiment: by setting up bird netting, it is possible to prevent external birds from entering the enclosure 1 to eat the feed.

[0040] As a technical optimization of this utility model, a temperature and humidity sensor 8 is installed on the top surface inside the housing 1, and an ammonia sensor 9 and a PLC touch screen all-in-one machine 901 are installed on the side wall.

[0041] In this embodiment, the PLC touch screen all-in-one machine 901 is electrically connected to the temperature and humidity sensor 8, the ammonia sensor 9 (GDD4NH3-50 electrochemical ammonia sensor), the first fan 301, the hot air fan 401, and the second fan 702, respectively, so as to control the operation of each component.

[0042] As a technical optimization of this utility model, a photovoltaic panel 103 is fixedly installed on the top of the housing 1, and a storage battery 104 is fixedly installed on the top of the housing 1 below the photovoltaic panel 103.

[0043] In this embodiment: solar energy is converted into electrical energy by photovoltaic panel 103 and stored in battery 104. Battery 104 is connected to various operating components to provide power for the operation of each operating component.

[0044] The working principle and usage process of this utility model are as follows: When in use, the temperature and humidity sensor 8 can monitor the temperature inside the housing 1, and the ammonia sensor 9 can monitor the concentration of ammonia inside the housing 1. By setting the temperature range inside the housing 1 and the concentration of ammonia sensor 9 on the PLC touch screen all-in-one machine 901, the PLC touch screen all-in-one machine 901 controller can correspondingly control the operation of the first fan 301, the hot air fan 401 and the second fan 702.

[0045] When ventilating, the first fan 301 at both ends of the ventilation pipe 2 is activated, allowing fresh air from the outside to enter the ventilation pipe 2 through the first air inlet pipe 3 and the connecting pipe 302, and to be discharged from multiple air outlets 201 at the bottom of the ventilation pipe 2 to form a "vertical airflow curtain". The electric actuator 502 is activated to push the ventilation window 501 to rotate and open the ventilation window 501. The airflow in the shed 1 can be discharged through the ventilation port 5, achieving uniform air supply from top to bottom, avoiding the ventilation dead corners caused by traditional side air supply. The PLC touch screen all-in-one machine 901 can adjust the ventilation volume of the ventilation port 5 according to the temperature. Therefore, in hot weather, by increasing the ventilation volume of the ventilation port 5, a large amount of cool air from the outside can be quickly introduced, accelerating the heat dissipation in the shed, reducing the temperature in the shed, avoiding heat stress in livestock due to high temperature, and ensuring their normal growth and production performance. In cold seasons, reducing the ventilation volume can reduce heat loss in the shed, maintain a warm environment, and prevent livestock from freezing. For example, when the temperature is low at night in winter, appropriately reducing the ventilation volume can keep the temperature in the shed stable.

[0046] When the indoor temperature of dormitory 1 is low and ventilation is required, the hot air blower 401 is turned on. The cold air is heated through the second air inlet pipe 4 and enters the ventilation pipe 2, and the warm air is sent out from multiple air outlets 201.

[0047] During ventilation, the manure falls into the manure collection tank 6 through the manure drop hole 601. The second fan 702 is activated to force ventilation, allowing the airflow to enter the filter box 7. The activated carbon filter plate 701 absorbs the odor, thus playing a role in ventilation and deodorization, reducing odor, improving the surrounding environment of the farm, and reducing the impact on the lives of surrounding residents.
