It can introduce fresh air, expel harmful gases such as ammonia and carbon dioxide, reduce dust concentration, and improve air quality; it can also regulate temperature and humidity, reduce stress response in pigs, and reduce the incidence of respiratory diseases.

[0003] In the current technology, pigsties are often ventilated by installing multiple ventilation fans. However, when the ventilation fans are in use, the air they generate can only ventilate the area directly in front of them, and the ventilation effect on the sides is relatively poor. This can easily cause the accumulation of polluted air inside the pigsty, which can affect the health of the pigs. Therefore, a pigsty ventilation regulation device is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 An embodiment of this utility model is provided: a pigsty ventilation regulation device, including a wall 1 for supporting the whole device and isolating the inside of the pigsty from the outside. The inner wall of the wall 1 is equipped with a ventilation fan 5 for accelerating the exchange of gas inside the pigsty with the outside gas. The front surface of the wall 1 is provided with a diversion component 2 for guiding the air generated by the rotation of the ventilation fan 5 through a disassembly component 3 for easy replacement of the diversion plate 24 by the operator.

[0033] The airflow guiding assembly 2 includes a rotating shaft 23 for supporting the rotation of the airflow guiding plate 24. Multiple sets of rotating shafts 23 are arranged in a linear array directly in front of the ventilation fan 5. A lower fixed plate 22, with an arc-shaped groove 26, is rotatably connected to the lower part of the outer wall of the rotating shaft 23 to support the slider 210 and the rotating shaft 23. An upper fixed plate 21, also with an arc-shaped groove 26, is movably connected to the upper part of the outer wall of the rotating shaft 23. An airflow guiding plate 24, which guides airflow to the left and right sides of the fan to increase the fan's effective range, is fixedly connected to the upper and lower ends of the airflow guiding plate 24. The sliding rods 25, which drive the deflection of the diversion plate 24 through the sliding rods 25, are multiple in number when the middle limiting frame 29 slides with the limiting frame 28. The inner walls of the lower fixed plate 22 and the upper fixed plate 21 are provided with arc-shaped grooves 26 to restrict the movement of the sliding rods 25, so that the movement trajectory of the sliding rods 25 matches the movement trajectory of the diversion plate 24. The outer wall of the sliding rods 25 slides on the inner wall of the arc-shaped grooves 26. The lower surface of the lower fixed plate 22 is slidably connected to the middle of the middle limiting frame 29, which supports the middle limiting frame 29 and allows the middle limiting frame 29 to move only left and right. The rear surface of the slider 210 is fixedly connected to the middle limiting frame 29 to accommodate the sliding of the sliding rods 25.

[0034] Reference Figures 2-4 Both sides of the central limiting frame 29 are fixedly connected to linkage plates 27, which synchronously drive the limiting frame 28 to move when the central limiting frame 29 moves. The end of the linkage plate 27 away from the central limiting frame 29 is fixedly connected to the limiting frame 28 for accommodating the sliding rod 25. The outer walls of the multiple sets of sliding rods 25 located at the bottom are slidably connected to the inner walls of the limiting frame 28 and the central limiting frame 29, respectively. The lower surface of the slider 210 is provided with a drive assembly 4 for driving the central limiting frame 29 to move. It includes a motor 41 for driving the swing rod 42 to rotate. The upper surface of the motor 41 is mounted on the lower surface of the lower fixed plate 22. The output shaft of the motor 41 is fixedly connected to the swing rod 42 for driving the push rod 43 to move via a coupling. The side of the swing rod 42 away from the motor 41 is rotatably connected to the push rod 43 for pulling the push rotating rod 44 to move. The end of the push rod 43 away from the guide plate 24 is rotatably connected to the rotating rod 44 for connecting the push rod 43 and the slider 210 together.

[0035] Reference Figures 3-5The upper surface of the rotating rod 44 is fixedly connected to the lower surface of the slider 210. The slider 210 is T-shaped to increase the connection between the slider 210 and the lower fixed plate 22. The slider 210 is adapted to the inner wall of the middle part of the lower fixed plate 22. The disassembly assembly 3 includes a support plate 31 for supporting the limiting seat 32. The rear surface of the support plate 31 is fixedly connected to the front surface of the wall 1. The front surface of the support plate 31 is fixedly connected to a flexible steel limiting seat 32 for temporarily limiting the rotating shaft 23 after the upper fixed plate 21 is removed. The outer wall of the rotating shaft 23 is movably connected to the inner wall of the limiting seat 32. The rear part of the upper surface of the upper fixed plate 21 is fixedly connected to an extension plate 33 for accommodating bolts 34. The extension plate 33 is threadedly connected to the front surface of the wall 1 by bolts 34. The limiting seat 32 is U-shaped so that the limiting seat 32 can better stabilize the rotating shaft 23.

[0036] Working principle: First, when ventilation is needed inside the pigsty, the ventilation fan 5 can be turned on first, followed by the motor 41. The output shaft of the motor 41 rotates, which drives the swing rod 42 to start rotating. During the rotation of the swing rod 42, it will pull the push rod 43. The push rod 43 will transmit the force to the rotating rod 44 and simultaneously make the slider 210 move. The slider 210 is restricted by the inner wall of the lower fixed plate 22, so that the movement trajectory of the slider 210 is left and right sliding.

[0037] The movement of slider 210 causes the middle limiting frame 29 to move, which in turn causes the linkage plates 27 at both ends to pull the limiting frame 28 to move. During the movement of the middle limiting frame 29 and the limiting frame 28, the slider 25 will be continuously squeezed. Since the slider 25 and the diversion plate 24 are fixedly connected, when the slider 25 moves along the arc groove 26, the diversion plate 24 will swing left and right around the rotating shaft 23 in sync, guiding the air to other parts of the pig house and preventing gas accumulation.

[0038] When the operator finds that a drainage plate 24 is damaged, the bolt 34 can be removed. After the bolt 34 is removed, the fixation of the upper fixing plate 21 is canceled. At this time, the upper fixing plate 21 can be removed. Since the upper part of the outer wall of the rotating shaft 23 is movably connected to the inner wall of the upper fixing plate 21, when the upper fixing plate 21 is removed, the rotating shaft 23 can be temporarily fixed by the limiting seat 32 for a period of time to prevent multiple drainage plates 24 from tipping over due to the loss of upper fixation after the upper fixing plate 21 is removed. The rotating shaft 23 and drainage plate 24 that need to be replaced are removed, and the new rotating shaft 23 is pressed into the inner wall of the limiting seat 32 to complete the replacement.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
