[0006] Furthermore, a mounting block is provided in the middle of the front wall surface of the rotating plate.

[0007] Furthermore, one end of the cleaning brush is fixedly installed to the outer wall of the mounting block by bolts.

[0008] Furthermore, an annular groove is formed on the circumferential side wall of the inner cavity of the circular shell.

[0009] Furthermore, a limiting slip ring is fixedly connected to the outer circumferential wall of the internal gear ring and slidably connected to the inside of the annular groove.

[0010] Furthermore, a drive rod is rotatably connected to the middle of the rear wall of the inner cavity of the circular shell, and a drive pinion is fixedly installed on the outer wall of the front end of the drive rod.

[0011] Furthermore, a driven rotating rod is rotatably connected to the bottom of the rear wall of the inner cavity of the circular shell, and a driven large gear is fixedly installed on the outer wall of the front end of the driven rotating rod.

[0014] This utility model provides a ventilation and air exchange device for pigeon houses used in meat pigeon farming. It has the following beneficial effects:

[0015] 1. A ventilation and air exchange device for pigeon coops used in meat pigeon farming, through the setting of a linkage mechanism, when in use, the ventilation pipe is fixed in a hole opened in the wall, the ventilation component is turned on, the motor on the ventilation component drives the fan blades on the rotating shaft to rotate at high speed to generate airflow for ventilation and air exchange in the pigeon coop. Since the rear end of the drive rod is inserted into the hexagonal connecting slot on the front end of the rotating shaft of the ventilation component through the hexagonal connecting rod, the rotating shaft of the ventilation component can drive the drive pinion to rotate through the hexagonal connecting rod and the drive rod, forcing the driven large gear meshing with the drive pinion and the axis of the driven rod to rotate, thereby forcing the internal gear ring meshing with the driven large gear to rotate along the inner cavity of the circular housing. The limiting slip ring is connected to the inner cavity of the annular sliding groove. The internal gear ring forms a limiting and guiding effect within the circular housing cavity. The internal gear ring, through a rotating plate, drives the cleaning brush to rotate along the filter screen surface, cleaning it and ensuring the filter's filtration efficiency. Because the rotational speed of the ventilation component's shaft is reduced through the meshing transmission between the driving pinion, driven gear, and internal gear ring, the cleaning brush can maintain a low rotation speed, reducing wear. The cleaning brush is fixed to a mounting block on the front wall of the rotating plate with bolts, facilitating easy connection and maintenance by operators. This simple and practical operation, coupled with a reasonable and compact structure, enables the cleaning brush to rotate at low speed, effectively cleaning the filter screen, extending the equipment's service life, and improving its safety.

An air exchange assembly 12 is disposed inside the ventilation duct 10. The atomizing assembly 11 and the air exchange assembly 12 are existing technologies and will not be described in detail. A filter screen 13 is fixedly installed at the front end of the ventilation duct 10. A cleaning brush 14 is provided on the front surface of the filter screen 13. A circular housing 15 is fixedly fitted into the middle of the filter screen 13. A rotating plate 17 is slidably connected to the front end of the circular housing 15. One end of the cleaning brush 14 is fixedly installed to the front end of the rotating plate 17. The cleaning brush 14 is located away from... One end of the rotating plate 17 is in contact with the front surface of the filter screen 13. The circular housing 15 contains a linkage mechanism for driving the cleaning brush 14 to rotate. This linkage mechanism includes an internal gear ring 16 rotatably connected to the inner wall of the circular housing 15, a driving pinion 19 rotatably connected to the middle of the inner wall of the circular housing 15, and a driven large gear 21 rotatably connected to the bottom of the rear wall of the circular housing 15. The upper and lower ends of the driven large gear 21 mesh with the bottom end of the driving pinion 19 and the bottom end of the internal gear ring 16, respectively. The rear end of the 9 is provided with a hexagonal connecting rod 22 that connects to the front end of the rotating shaft of the ventilation component 12. A mounting block 171 is provided in the middle of the front wall of the rotating plate 17. One end of the cleaning brush 14 is fixedly installed to the outer wall of the mounting block 171 by bolts. An annular groove 151 is provided on the circumferential side wall of the inner cavity of the circular housing 15. A limiting slip ring 161 that slides inside the annular groove 151 is fixedly connected to the outer circumferential wall of the internal gear ring 16. A drive rod 18 is rotatably connected to the middle of the rear wall of the inner cavity of the circular housing 15. A drive pinion 19 is fixedly installed on the drive rod. On the front outer wall of the driving rod 18, a driven rod 20 is rotatably connected to the bottom of the rear wall of the inner cavity of the circular housing 15. A driven large gear 21 is fixedly installed on the front outer wall of the driven rod 20. The rear end of the driving rod 18 extends through the rear wall of the inner cavity of the circular housing 15 to the outside. The front end of the hexagonal connecting rod 22 is fixedly installed with the rear end of the driving rod 18. The front end of the rotating shaft of the ventilation assembly 12 is provided with a hexagonal connecting slot 23 that is adapted to the rear end of the hexagonal connecting rod 22. The rear end of the hexagonal connecting rod 22 is inserted into the hexagonal connecting slot 23.

[0024] The working principle of this utility model is as follows: In use, the ventilation pipe 10 is fixed in the hole opened in the wall. The ventilation assembly 12 is turned on, and the motor on the ventilation assembly 12 drives the fan blades on the rotating shaft to rotate at high speed, generating airflow to ventilate the pigeon house. Since the rear end of the drive rod 18 is inserted into the hexagonal connecting slot 23 on the front end of the rotating shaft of the ventilation assembly 12 via the hexagonal connecting rod 22, the rotating shaft of the ventilation assembly 12 can drive the drive pinion 19 to rotate via the hexagonal connecting rod 22 and the drive rod 18. This forces the driven large gear 21, which meshes with the drive pinion 19, and the driven rod 20 to rotate, thereby forcing the internal gear ring 16, which meshes with the driven large gear 21, to rotate along the inner cavity of the circular housing 15. The limiting slip ring 161 slides within the annular groove 151 to control the internal gear ring 16. The circular housing 15 forms a limiting and guiding effect within its inner cavity. The internal gear ring 16 drives the cleaning brush 14 to rotate along the surface of the filter screen 13 via the rotating plate 17, cleaning the surface of the filter screen 13 and ensuring the filtration effect of the filter screen 13. Because the rotational speed of the air exchange component 12 shaft is reduced through the meshing transmission between the driving pinion 19, the driven gear 21, and the internal gear ring 16, the cleaning brush 14 can maintain a low-speed rotation, reducing the wear of the cleaning brush 14. The cleaning brush 14 is fixedly installed to the mounting block 171 on the front wall of the rotating plate 17 by bolts, making it convenient for operators to plug and install the cleaning brush 14 for maintenance. The above operation is simple and practical, and the structure is reasonable and compact. This device enables the cleaning brush 14 to rotate at a low speed to clean the filter screen 13, extending the service life of the device and improving the safety of its use.
