[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Depend on Figures 1 to 5 The utility model includes a chicken house wall 1, a circular metal pipe 2, a circular fan housing 3 and an air supply fan 4. The circular metal pipe 2 is installed on the chicken house wall 1. The circular metal pipe 2 can be installed at different heights on the chicken house wall 1 according to actual needs. The air supply fan 4 is installed inside the circular fan housing 3. A filter screen 5 is installed at one end of the circular fan housing 3. Two fixing blocks 6 are symmetrically fixedly installed on the surface of the circular metal pipe 2 located outside the chicken house wall 1. A connecting mounting cover 7 is fixedly installed on one end of the surface of the circular fan housing 3 close to the circular metal pipe 2. Two T-shaped pins 8 movably connected to the fixing blocks 6 are symmetrically installed inside the connecting mounting cover 7. The two fixing blocks 6 are both crescent-shaped structures. Two slide grooves 9 are symmetrically opened on the arc surfaces of the two crescent-shaped fixing blocks 6. The two slide grooves 9 are both inclined, and a socket 10 is opened in the middle of the arc surfaces of the two crescent-shaped fixing blocks 6. The socket 10 is located between the two slide grooves 9, and the lower part of the T-shaped pin 8 is movably inserted into the inside of the socket 10.

[0017] Two inner grooves 11 are symmetrically provided inside the connection and installation cover 7, and two T-shaped pins 8 are movably plugged into the two inner grooves 11 respectively, and a spring 12 is fixedly connected between the inner grooves 11 and the T-shaped pins 8, and an inverted convex inner groove 16 is provided at one end of the connection and installation cover 7, and the inverted convex inner groove 16 matches the circular metal pipe 2, and the circular metal pipe 2 is plugged into the inverted convex inner groove 16, and a clamping rubber ring 17 is fixedly connected to one end of the circular metal pipe 2, so that the circular fan housing 3 can be effectively installed and connected to the circular metal pipe 2;

[0018] During installation, align the inverted convex inner groove 16 on the connection and installation cover 7 with the circular metal pipe 2, insert one end of the circular metal pipe 2 and the clamping rubber ring 17 into the inside of the inverted convex inner groove 16, and at the same time, make the two T-shaped pins 8 located on the surface of the circular metal pipe 2, and then rotate the connection and installation cover 7 to make the connection and installation cover 7 drive the two T-shaped pins 8 to move into any one of the slide grooves 9 on the surfaces of the two fixed blocks 6, and then continue to rotate the connection and installation cover 7 to make the connection and installation cover 7 drive the T-shaped pins 8 to move inside the slide groove 9. Due to the inclined setting of the slide groove 9, the movement of the T-shaped pins 8 will drive the connection and installation cover 7 to move. The circular metal pipe 2 is pressed and the T-shaped pin 8 is moved, and the T-shaped pin 8 is squeezed and moved to the inside of the inner groove 11 to compress the spring 12, and at the same time, the inside of the inverted convex inner groove 16 squeezes the clamping rubber ring 17 to firmly pressurize the connecting and mounting cover 7 and the circular metal pipe 2. Finally, after the T-shaped pin 8 moves and aligns with the insertion hole 10, the elastic force of the spring 12 will make the T-shaped pin 8 inserted into the inside of the insertion hole 10, so that the connecting and mounting cover 7 drives the circular fan housing 3 to be firmly and stably installed and connected to the circular metal pipe 2; the setting of the clamping rubber ring 17 prevents the connecting and mounting cover 7 and the circular fan housing 3 from shaking when the blower 4 is started.

[0019] The ventilation device for a chicken farm has a connection and fixing structure that is easy to disassemble and assemble. The connection and fixing structure enables the ventilation device to be disassembled and assembled by hand without using tools, thereby effectively improving the convenience and practicality of the ventilation device.

[0020] The ends of the two T-shaped latches 8 located inside the inner groove 11 are fixedly connected with connecting pins 13, and the two connecting pins 13 extend to the surface of the connecting and mounting cover 7 and are fixedly installed with bow-shaped toggle blocks 14. The surface of the connecting and mounting cover 7 is symmetrically fixedly connected with two handles 15, and the two bow-shaped toggle blocks 14 are respectively located on the inner sides of the two handles 15, so that the holding and disassembly operations can be effectively performed;

[0021] During disassembly, the operator holds the two handles 15 with both hands, and then uses the index finger, middle finger, ring finger and little finger to respectively move the two sides of the bow-shaped toggle block 14, so that the bow-shaped toggle block 14 drives the connecting pin 13 to move. The movement of the connecting pin 13 will pull the T-shaped latch 8 to move, so that the T-shaped latch 8 compresses the spring 12 and withdraws the T-shaped latch 8 from the inside of the socket 10, and then rotates the connecting and mounting cover 7 through the two handles 15 to make the T-shaped latch 8 slide inside the slide groove 9, and finally separates the two T-shaped latches 8 from the two fixing blocks 6, and then removes the connecting and mounting cover 7 from the circular metal pipe 2 to complete the disassembly.

[0022] At the same time, the ventilation device used in chicken farms has a simple structural design, is convenient and easy to use and operate, and the ventilation device is installed and fixed stably and reliably, and its performance can meet people's use needs.
