Description

Technical Field

[0001] This utility model belongs to the field of animal husbandry technology, specifically relating to a ventilation device for sheepfold farming. Background Technology

[0002] In modern large-scale sheep farming, the ventilation system is a core facility for ensuring the healthy growth and production efficiency of sheep. Its importance is becoming increasingly prominent with the increase in stocking density and the popularization of standardized farming concepts. Inside the sheepfold, the sheep's respiration and the decomposition of feces continuously produce harmful gases such as ammonia and hydrogen sulfide. At the same time, the high humidity environment is prone to the growth of mold and pathogenic microorganisms. These factors are directly related to the respiratory health, feed conversion rate and reproductive performance of the sheep. In traditional farming practices, natural ventilation (such as side windows and skylights) was widely used due to its low cost. However, as the scale of farming expands (the number of sheep in a single sheepfold increases from dozens to hundreds or even thousands), its drawbacks, such as being constrained by climatic conditions (e.g., windless, hot and humid weather) and low ventilation efficiency, become increasingly apparent. To meet the environmental requirements of high-density farming, mechanical ventilation has gradually become the mainstream, with negative pressure ventilation systems dominating in small and medium-sized farms due to their ease of installation and moderate cost. The existing negative pressure ventilation method is highly dependent on the external environment. If there are pollution sources outside the shed, such as nearby manure yards or other farms, negative pressure ventilation will draw in external odors, dust, and even pathogens into the shed, increasing the risk of disease in the sheep flock and causing losses to farmers. Utility Model Content

[0003] The purpose of this utility model is to provide a ventilation device for sheep farming, which aims to solve the problem that the existing negative pressure ventilation method is more dependent on the external environment. If there are pollution sources outside the shed, such as nearby manure yards or other farms, negative pressure ventilation will draw in external odors, dust and even pathogens into the shed, increasing the risk of disease in the sheep flock and causing losses to farmers.

A filter screen 5 is fitted into the inner wall of the ventilation window 4, an activated carbon plate 6 is abutted against the surface of the filter screen 5, an insert 7 is connected to the surface of the activated carbon plate 6, a rubber block 8 is adhered to the surface of the insert 7, and the insert 7 and the rubber block 8 are engaged and connected to the surface of the slot 9, which is opened on the surface of the ventilation window 4. The wall surface abuts against the sealing ring 10, the surface of the sealing ring 10 is adhered to the surface of the activated carbon plate 6, the surface of the filter screen 5 away from the activated carbon plate 6 abuts against the cleaning bristles 11, the other side of the cleaning bristles 11 is connected to the cleaning plate 12, the two sides of the surface of the cleaning plate 12 are respectively adhered to the surface of the connecting block 13, the surface of the connecting block 13 is slidably connected to the surface of the limiting rod 14, the surface of the limiting rod 14 is connected to the movable groove inside the ventilation window 4, the top surface of the movable groove of the ventilation window 4 is adhered to the top block 15, and the bottom of the top block 15 is elastically connected to the connecting block 13 by the spring 16.

[0015] Preferably, a rectangular groove is provided on the inner wall of the ventilation window 4, the shape and size of which are adapted to the filter screen 5.

[0016] In practical use, the rectangular groove opened on the inner wall of the ventilation window 4 facilitates the use of the activated carbon plate 6 on its outer side to abut and fix the filter screen 5 in the position inside the ventilation window 4.

[0017] Preferably, the insert 7 has a "T" shaped integrated structure, the rubber block 8 has a hemispherical structure, and the shape and size of the slot 9 are adapted to the insert 7 and the rubber block 8.

[0018] In actual use, hold the handle on the activated carbon plate 6 and pull the activated carbon plate 6 away from the filter screen 5, so that the plug 7 and rubber block 8 connected on both sides are disengaged from the locking groove 9.

[0019] Preferably, the ventilation window 4 has a movable groove on the side away from the activated carbon plate 6, the shape and size of which are adapted to the cleaning plate 12 and the connecting block 13.

[0020] In actual use, pull the handle on the surface of the cleaning plate 12 so that it slides on the limiting rod 14 through the connecting blocks 13 on both sides, thereby restricting the cleaning plate 12 and the connecting blocks 13 connected to the surface from scraping up and down on the surface of the filter screen 5, thereby cleaning the impurities adhering to the surface of the filter screen 5.

[0021] Preferably, a circular through groove is formed longitudinally on the surface of the connecting block 13, and its shape and size are adapted to the limiting rod 14.

[0022] In practical use, the circular through groove on the surface of the connecting block 13 allows it to slide up and down on the limiting rod 14, thereby guiding and limiting the movement of the cleaning plate 12, so that the cleaning bristles 11 on the surface of the cleaning plate 12 can come into contact with the surface of the filter screen 5 to wipe away the impurities adhering to it.

[0023] Preferably, two sets of connecting blocks 13, limiting rods 14, top blocks 15 and springs 16 are symmetrically distributed on both sides of the cleaning plate 12.

[0024] In practical use, by using the spring 16 connected to the top of the connecting block 13, after the cleaning plate 12 is pulled down to clean and scrape the surface of the filter screen 5, the cleaning plate 12 can be pushed back by the spring 16 and stored in the inner wall of the ventilation window 4, thereby preventing it from blocking the surface of the filter screen 5 when it is not in use, thus affecting the ventilation effect of the sheepfold body 1.

[0025] Working principle: During sheep pen raising, after the axial flow fan 3 installed on one side of the sheep pen body 1 is started, it will force the air inside the sheep pen body 1 to be discharged to the outside, making the air pressure inside the pen lower than that outside, forming a "negative pressure" state. At this time, atmospheric pressure will push the fresh air outside into the pen, naturally rushing in from the ventilation window 4 on the opposite side, forming a directional airflow circulation of "outdoor → ventilation window 4 → pen inside → axial flow fan 3 → outdoor", realizing the replacement of stale air inside the pen with fresh air outside. When outdoor air enters the sheep pen body 1 through the ventilation window 4, the nylon mesh filter 5 embedded in the inner wall of the ventilation window 4 filters out dust and particles mixed in with the outside air. Physical pollutants such as particulate matter, insects, and down are filtered and intercepted to prevent these impurities from entering the shed and adhering to the sheep's body, feed, or equipment, thus reducing respiratory irritation and the risk of infection. At the same time, the outside air after being filtered by the filter screen 5 passes through the activated carbon plate 6 again. The activated carbon in the activated carbon plate 6 has a porous structure, and its micropores can adsorb odor molecules in the air through intermolecular forces, such as ammonia and hydrogen sulfide from the nearby manure yard, volatile organic compounds (VOCs), and some gaseous pollutants, reducing the odor concentration of the air entering the shed and reducing the interference of external pollution sources on the environment of the sheep shed itself. In addition, during use, the handle on the surface of the cleaning plate 12 can be pulled periodically to make it slide on the limiting rod 14 through the connecting blocks 13 on both sides, thereby restricting the cleaning plate 12 and the connecting blocks 13 connected to the surface from scraping up and down on the surface of the filter screen 5, thereby cleaning the impurities adhering to the surface of the filter screen 5 and preventing excessive impurities from adhering to the filter screen 5 and causing blockage. At the same time, the impurities brushed off by the connecting blocks 13 fall directly through the channel at the bottom of the ventilation window 4 under the action of gravity, and can be recycled using an external garbage recycling bin. After long-term use, one can enter the interior of the sheepfold body 1 through the door 2, then grasp the handle on the activated carbon plate 6 and pull the activated carbon plate 6 away from the filter screen 5, so that the plug 7 and rubber block 8 connected on both sides can be dislodged from the locking groove 9, making it convenient to replace the activated carbon plate 6 to maintain the filtering effect of the activated carbon inside on impurities in the air. Alternatively, after pulling out the locked activated carbon plate 6, the filter screen 5 that is attached to it can be removed and replaced. In addition, the sealing ring 10 adhering to the surface of the activated carbon plate 6 can enhance the sealing between the activated carbon plate and the ventilation window 4, preventing unfiltered air from entering the sheepfold through the gaps. The cleaning brush bristles 11 in this design are made of nylon, which has high wear resistance and toughness. It can repeatedly scrape the dust, lint and other impurities on the surface of the filter screen 5 without breaking easily. The material surface is smooth and does not easily absorb moisture and dirt in a humid environment. It leaves little residue after cleaning and is resistant to slight ammonia corrosion that may exist in the sheepfold.

[0026] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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.
