Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-5 , the embodiment of the present application provides a U-shaped ventilation system for animal husbandry, comprising:

[0032] A plurality of U-shaped air ducts 1, each of the plurality of U-shaped air ducts 1 comprises two first air ducts 11 arranged opposite to each other and a second air duct 12 connected to the bottom of the two first air ducts 11, the two first air ducts 11 are both located in the breeding house 4, and a first air outlet 111 is arranged on the opposite side of the two first air ducts 11, the second air duct 12 is located in the manure ditch 5, and a second air outlet 121 is arranged on the second air duct 12 along the first direction X;

[0033] An air inlet mechanism 2 is connected to the first air duct 11 of the plurality of U-shaped air ducts 1; and

[0034] The exhaust mechanism 3 is arranged at one end of the manure ditch 5, and the air inlet of the exhaust mechanism 3 is connected to the manure ditch 5.

[0035] In the present application, external fresh air is introduced into multiple U-shaped air ducts 1 through the air inlet mechanism 2, and is blown into the breeding house 4 through the first air outlet 111 of the first air duct 11 in the U-shaped air duct 1 to replenish fresh air for the inside of the breeding house 4. The fresh air is blown into the manure ditch 5 through the second air outlet 121 of the second air duct 12, and flows in the manure ditch 5 along the length direction of the manure ditch 5, and finally discharged through the exhaust mechanism 3, which can drive the air circulation in the entire manure ditch 5, thereby ensuring that the harmful gases generated in the manure ditch 5 can be fully discharged, ensuring the hygiene in the breeding house 4, and improving practicality.

[0036] Specifically, the U-shaped air duct 1 is formed by bending a rectangular tube, and the two first air ducts 11 of the U-shaped air duct 1 are arranged opposite to each other. The two first air ducts 11 of the U-shaped air duct 1 are respectively embedded in the insulation wall of the breeding house 4, and the opposite side of the first air duct 11 constitutes the inner wall of the breeding house 4, so that the U-shaped air duct 1 and the breeding house 4 form a whole, ensuring that there will be no protruding pipes in the breeding house 4, saving space, and reducing the damage of the U-shaped air duct 1 by the animals raised.

[0037] In the present application, the first air outlet 111 of the first air duct 11 on the U-shaped air duct 1 is used to supplement fresh air to the interior of the breeding house 4. The fresh air delivered by the relatively arranged first air duct 11 converges in the middle of the breeding house 4 and is dispersed into the entire breeding house 4. Compared with the existing top air supply form, the uniformity of the air supply is improved.

[0038] In the embodiment of the present application, the U-shaped air duct 1 further includes an air valve 13 disposed between the first air duct 11 and the second air duct 12 , for controlling the connection and blocking between the first air duct 11 and the second air duct 12 .

[0039] Specifically, the air valve 13 between the first air duct 11 and the second air duct 12 controls the connection and blocking between the first air duct 11 and the second air duct 12, and there are two modes for ventilation. The first mode is when the air valve 13 is closed. At this time, the fresh air is blown into the breeding house 4 only through the first air outlet 111 of the first air duct 11 to replenish the fresh air inside the breeding house 4. Then, the air in the breeding house 4 passes through the grille plate 6 under the action of the exhaust mechanism 3 and enters the manure ditch 5, and is discharged through the exhaust mechanism 3. This mode is used for normal ventilation. The second mode is when the air valve 13 is closed. When the grille plate 6 is turned on, fresh air is not only blown into the breeding house 4 through the first air outlet 111, but also blown into the manure ditch 5 through the second air outlet 121 of the second air duct 12, forming a continuous airflow in the manure ditch 5 that flows toward the exhaust mechanism 3, so that the harmful gases in the manure ditch 5 are fully discharged. A part of the air in the breeding house 4 still enters the manure ditch 5 through the grille plate 6, which can prevent the gas in the manure ditch 5 from flowing back into the breeding house 4. This mode is used to specifically discharge the harmful gases in the manure ditch 5, and can be performed intermittently or at the same time as the manure ditch 5 is discharging sewage.

[0040] like Figure 3-4 As shown, in one embodiment of the present application, a slope 122 facing the exhaust mechanism 3 is provided at the bottom of the second air duct 12, and the second air outlet 121 is provided on the slope 122, and the angle between the first direction X and the length direction of the manure ditch 5 is an acute angle.

[0041] In the present application, a slope 122 is arranged on the second air duct 12, and the second air outlet 121 is arranged on the slope 122, so that the wind blown out of the second air outlet 121 is directed toward the exhaust mechanism 3 and the bottom surface of the manure ditch 5, so that the airflow blown out of the second air outlet 121 can flow toward the exhaust mechanism 3 to form a continuous airflow, and the air blown out of the second air outlet 121 is directed toward the bottom surface of the manure ditch 5 to prevent the air in the manure ditch 5 from returning to the breeding house 4 during the circulation process.

[0042] like Figure 5 As shown, in another embodiment of the present application, the first direction X is the length direction of the manure ditch 5.

[0043] In the present application, the direction of the second air outlet 121 is along the length direction of the manure ditch 5, so that the wind blown out by the second air outlet 121 can carry the harmful gas in the manure ditch 5 to form a continuous airflow, and finally be discharged by the exhaust mechanism 3. A part of the air in the breeding house 4 will still continue to enter the manure ditch 5 through the grille plate 6, which can prevent the gas in the manure ditch 5 from returning to the breeding house 4.

[0044] In the embodiment of the present application, a plurality of U-shaped air ducts 1 are arranged at equal intervals in the breeding house 4 , and a first air outlet 111 on the first air duct 11 is inclined toward the manure ditch 5 .

[0045] In the present application, the fresh air blown out from the first air outlet 111 on the first air duct 11 enters the breeding house 4 and flows downward, and can directly ventilate the bottom of the breeding house 4 to ensure the ventilation effect.

[0046] Specifically, the first air outlet 111 on the first air duct 11 includes a middle air outlet and side air outlets located on both sides of the middle air outlet, wherein the middle air outlet and the side air outlet both blow air downward, and the side air outlets blow air to both sides, so that the air blown into the breeding house 4 by the first air outlet 111 can quickly fill the entire breeding house 4, thereby improving the air supply effect.

[0047] Furthermore, an air guide cap 112 is provided at the first air outlet 111 of the first air duct 11 to control the air outlet direction at the first air outlet 111 .

[0048] In the present application, the wind direction is guided by the wind guide cap 112 at the first air outlet 111 .

[0049] Optionally, the first air outlet 111 may be directly configured as an oblique opening to control the air supply direction at the first air outlet 111 .

[0050] In the embodiment of the present application, bosses 123 for placing the grille plate 6 are provided on both sides of the top of the second air duct 12 , and the top of the second air duct 12 and the top of the grille plate 6 are located in the same plane.

[0051] Specifically, there is a grille plate 6 between the breeding house 4 and the manure ditch 5. The animals are raised on the grille plate 6, and the feces and urine fall into the manure ditch 5 below through the grille plate 6. The grille plate 6 is supported by the boss 123 on the second air duct 12, so that the grille plate 6 is flush with the top surface of the second air duct 12, thereby ensuring the flatness of the ground in the breeding house 4.

[0052] In the embodiment of the present application, the air intake mechanism 2 includes an air intake fan 21 and an air intake duct 22 connected to the output end of the air intake fan 21 , and the output end of the air intake duct 22 is connected to the first air duct 11 of the U-shaped air duct 1 .

[0053] In the present application, the air intake fan 21 delivers clean air from the outside into the U-shaped air duct 1 through the air intake duct 22. Specifically, two air intake ducts 22 are provided, one of which is connected to the tops of multiple first air ducts 11 of multiple U-shaped air ducts 1, and the other air intake duct 22 is connected to the tops of another first air duct 11 of the multiple U-shaped air ducts 1, so that the two first air ducts 11 of the U-shaped air duct 1 supply air evenly, thereby improving the air supply effect.

[0054] Furthermore, the air intake mechanism 2 also includes an air conditioner arranged at the input end of the air intake fan 21 for adjusting the temperature of the intake air.

[0055] In the present application, the temperature of the air entering the air inlet duct 22 can be adjusted by air conditioning. The temperature is first adjusted to the required temperature and then sent into the breeding house 4, thereby playing a role in regulating the temperature in the breeding house 4.

[0056] Optionally, a filter assembly may be provided on the air inlet mechanism 2 to filter the air sent into the air inlet duct.

[0057] Optionally, a sterilization component may be provided on the air inlet mechanism 2 to sterilize the air sent into the air inlet duct. Specifically, the sterilization component may be an ultraviolet lamp.

[0058] In the embodiment of the present application, the exhaust mechanism 3 includes an exhaust air duct 31 connected to the manure ditch 5 and an exhaust fan 32 connected to the exhaust air duct 31 .

[0059] In the present application, under the action of the exhaust fan 32, the gas in the manure ditch 5 enters the exhaust duct 31 and is then discharged. Specifically, the exhaust duct 31 is a channel enclosed by the partition and the side wall of the breeding house 4. The bottom of the channel is connected to the manure ditch 5, and the top of the channel is connected to the exhaust fan 32.

[0060] When in use, the external fresh air is introduced into the multiple U-shaped air ducts 1 through the air inlet mechanism 2, and is blown into the breeding house 4 through the first air outlet 111 of the first air duct 11 in the U-shaped air duct 1, so as to replenish the fresh air for the inside of the breeding house 4, and the fresh air is blown into the manure ditch 5 through the second air outlet 121 of the second air duct 12, and flows in the manure ditch 5 along the length direction of the manure ditch 5, and finally discharged through the exhaust mechanism 3, which can drive the air circulation in the entire manure ditch 5, thereby ensuring that the harmful gases generated in the manure ditch 5 can be fully discharged, ensuring the hygiene in the breeding house 4, and improving practicality.
