[0019] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0021] like Figure 1 As shown, a precision air supply device for boar pens is an improvement on the existing pens structure. It includes an air storage tank 2, an air compressor 1, and at least one set of pens 5 installed on the floor of the pens. In boar pens, each pen typically has one pen per pig. A horizontal bar is fixedly installed at the top of each pen. The rear horizontal bar 4, located behind the pig's rump, is made of a round tube and is hollow inside. Multiple sets of rear horizontal bars 4 are connected in series. The side wall of the rear horizontal bar 4 facing the pig has... Several air outlets 43 are arranged along the length of the pen and point towards the corresponding pigs in the pen; the air compressor 1 and the air storage tank 2 are both fixed on the ground, wherein the outlet of the air compressor 1 is connected to the lower inlet of the air storage tank 2, and the upper outlet of the air storage tank 2 is connected to one end of the rear horizontal bar 4 in the pigpen 5 through an air supply pipe 3. The end of the rear horizontal bar 4 away from the connection end of the air supply pipe 3 is sealed, so that the supplied air is blown outward from the multiple air outlets 43, such as... Figure 5 As shown, the airflow is diffused, covering the parts of the pig that require precise airflow.

[0022] A further optimized technical solution is provided, in which the aforementioned rear horizontal bar 4 includes an inner tube 41 and an outer tube 42 coaxially fitted together, such as... Figure 2As shown, the outer tube 42 is welded and fixed to the top of the pigpen 5. The inner tube 41 and the outer tube 42 can rotate relative to each other. The inner tube 41 has multiple air outlets 43 arranged along its tangent on its circumferential sidewall, which correspond one-to-one with multiple sets of pigpen 5. At least one actuating rod 44 perpendicular to the inner tube 41 is also fixedly installed on the circumferential sidewall of the inner tube 41. Corresponding to the inner tube 41, the outer tube 42 has multiple ventilation slots 45 on its circumferential sidewall. Each ventilation slot 45 is arranged along the circumference of the outer tube 42 and is located in the lower middle part of the outer tube 42 facing the pig. The air outlets 43 on the inner tube 41 are located within the opening range of the ventilation slots 45. The outer tube 42 also has the same number of actuation slots 46 as the actuation rods 44. The actuation slots 46 are also arranged along the circumference of the outer tube 42, and their length can be greater than or equal to the length of the ventilation slots 45. The actuation rods 44 on the inner tube 41 are placed in the corresponding actuation slots 46 and can slide along their length, thereby driving the inner tube 41 and the outer tube 42 to rotate, thereby controlling the air outlet direction of the air outlets 43, so as to meet the needs of boars of different ages, lengths, and heights for precise air blowing and cooling.

[0023] Furthermore, the aforementioned inner tube 41 is provided in multiple units, each corresponding to a group of pigpens 5, and is coaxially placed inside the aforementioned outer tube 42; each inner tube 41 is provided with an air outlet 43 and a lever 44. Correspondingly, the aforementioned outer tube 42 is provided with multiple ventilation slots 45 and lever slots 46, the same number as the groups of pigpens 5, which are adapted to the aforementioned inner tube 41, enabling precise control of the air outlet direction of a single group of pigpens 5.

[0024] To improve the control precision of the air outlet direction, refer to Figure 3 As shown, the side wall of the aforementioned actuating groove 46 is provided with a plurality of equidistant limiting grooves 48 arranged along its length; correspondingly, refer to Figure 4 As shown, a limiting protrusion 47 is fixedly installed on the outer circumferential side wall of the actuating lever 44. The limiting protrusion 47 can be locked in the corresponding limiting groove 48, thereby fixing the air outlet direction of the air outlet 43 on the inner tube 41.

[0025] Each of the above 43 air outlets is fixedly equipped with a filter screen to prevent impurities from being blown out and to prevent damage to specific parts of the pigs.

[0026] In a further optimized technical solution, an air outlet baffle is slidably installed on the inner side of the air outlet 43 on the inner tube 41, the area of ​​which is larger than the area of ​​the air outlet 43; an outwardly extending lever is also fixedly installed on the air outlet baffle, passing through the inner tube 41 and slidably connected to it. By moving the lever, the air outlet baffle can be moved, the air outlet area of ​​the air outlet 43 can be adjusted, thereby controlling the air volume.

[0027] As another embodiment of this utility model, the positions of the inner tube 41 and the outer tube 42 can be interchanged according to the actual design structure of the pigpen 5, so that the inner tube 41 is coaxially fitted on the outside of the outer tube 42, and the outer tube 42 is also welded and fixed to the rear top of the pigpen 5; the outer tube 42, which is placed on the inner side, is also provided with a ventilation slot 45, and the inner tube 41 is adjusted and fastened to the outer tube 42 by rotating the clamp. The front side of the inner tube 41 is provided with a through air outlet 43, the center of which is placed on the central axis of the corresponding ventilation slot 45 along its length. The angle of the air outlet 43 can be adjusted by rotating the inner tube 41. After the angle adjustment is confirmed, it is clamped and fixed by clamp to ensure that the air outlet 43 blows air precisely to the specific position of the pig.

[0028] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
