Description

Technical Field

[0001] The utility model relates to the technical field of animal breeding, and more particularly to an oxygen-enriched ventilation device used in animal breeding. Background Art

[0002] Animal husbandry refers to the production activities of domesticated animals such as livestock and poultry, which are transformed into livestock products through artificial breeding and reproduction. Animal husbandry is an important part of agriculture. In order to ensure the hygiene of the breeding environment, the animal breeding sites can be ventilated through oxygen-enriched ventilation devices to reduce the occurrence of animal diseases.

[0003] Based on the above, the inventors found that the existing oxygen-enriched ventilation device ventilates and exchanges air through the air outlet, but when the device stops working, external dust and impurities can easily penetrate back into the pipes of the device through the air outlet. Over time, it is easy to cause poor air circulation. Therefore, in view of this, the inventors studied and improved the existing structure and provided an oxygen-enriched ventilation device for animal husbandry, in order to achieve a more practical purpose.

[0028] The guide mechanism 12 includes a pair of guide frames 13, and a support rod 14 is arranged on the inner side of the guide frame 13. One end of the support rod 14 is fixedly connected to a limit ring 15, and the middle part of the limit ring 15 is movably connected to a resistance-reducing ball 16. In order to ensure the movement stability of the seal and extend the service life of the seal, the guide mechanism 12 is provided.

[0029] See Figure 2A ventilation fan is fixedly connected to the center of the interior of the bellows 1, and an oxygen-enriched membrane 7 is fixedly connected to the other end of the bellows 1. The outlet pipe 3 is fixed above the breeding building so that multiple air outlets 4 are located in different breeding houses. Then the fan is started to allow external air to enter the bellows 1, and then the oxygen-enriched membrane 7 filters it to increase the oxygen content in the air. Then, the oxygen-enriched air is discharged from the air outlet 4 through the connecting pipe 2 and the outlet pipe 3 to ventilate the breeding house.

[0030] See Figure 3 The screw rod 8 is located in the center of the air outlet pipe 3 and is movably connected to the air outlet pipe 3. The drive motor 6 is started. Under the action of the screw rod 8, the ball slider 9 drives the support plate 10 to slide.

[0031] See Figure 3 The support plate 10 and the connecting rod 11 are arranged in a T shape, and the outer end of the connecting rod 11 is fixedly connected to the sealing cover 5. The support plate 10 enables the connecting rod 11 to drive the sealing cover 5 to slide inward, so that it is engaged with the air outlet 4, making the air outlet 4 sealed.

[0032] See Figure 4 The two guide frames 13 are symmetrically arranged, and the two guide frames 13 are fixedly connected to the inside of the air outlet 4 on both sides respectively, and the guide frames 13 support the support rods 14.

[0034] See Figure 4 A guide groove is provided inside the guide frame 13, and the resistance reducing ball 16 is located inside the guide groove. The movement of the support rod 14 causes the limit ring 15 to drive the resistance reducing ball 16 to move inside the guide frame 13. At the same time, the resistance reducing ball 16 rubs against the inner surface of the guide frame 13, thereby rotating and reducing the movement resistance.

[0035] During use: fix the air outlet pipe 3 above the breeding building so that multiple air outlets 4 are located in different breeding houses. When ventilation is needed, start the fan to allow external air to enter the bellows 1 and be filtered by the oxygen-enriched membrane 7 to increase the oxygen content in the air. Then, through the connecting pipe 2 and the air outlet pipe 3, the oxygen-enriched air is discharged from the air outlet 4 to ventilate the breeding house. When the device is idle, start the drive motor 6. Under the action of the screw rod 8, the ball slider 9 drives the support plate 10 to slide, and the support plate 10 drives the connecting rod 11 to The sealing cover 5 slides inward so that it is engaged with the air outlet 4, so that the air outlet 4 is in a sealed state, preventing external dust and impurities from entering the interior of the device pipe, and the connecting rod 11 drives the support rod 14 to adjust synchronously during the movement, and the guide frame 13 cooperates with the support rod 14 to support the connecting rod 11 for movement, and the movement of the support rod 14 causes the limit ring 15 to drive the resistance reducing ball 16 to move inside the guide frame 13, and the resistance reducing ball 16 rubs against the inner surface of the guide frame 13, thereby rotating, reducing the movement resistance, and thus extending the service life of the sealing component.
