Description

Technical Field

[0001] This utility model relates to the field of chicken coop ventilation technology, specifically a fresh air device for chicken coop ventilation. Background Technology

[0002] A chicken coop refers to a place or building used for raising chickens. A fresh air ventilation system for chicken coops is used to improve air quality, regulate temperature and humidity, and remove harmful gases, creating a good growth environment for the chickens. For example, a ventilation and air exchange device for chicken coops, with announcement number CN222967691U, uses an exhaust fan to expel waste gas from inside the chicken coop to the outside. Simultaneously, the waste gas exchanges heat with heat exchange tubes. Then, under atmospheric pressure, fresh air from outside is introduced into the heat exchange tubes through an intake pipe for heat exchange. This ensures that the fresh air delivered to the chicken coop does not cause a rapid drop or rise in temperature after heat exchange, and the temperature inside the chicken coop only needs to be readjusted within a small range. This structure allows for the reuse of waste gas, reducing resource waste.

[0003] While the aforementioned technology can expel exhaust gases from inside the chicken house to the outside while exchanging heat with the exhaust gases through contact with heat exchange pipes, it suffers from a problem: the fresh air entering the chicken house cannot be evenly distributed. This uneven distribution of fresh air leads to significant temperature differences between different areas of the chicken house. Fresh air concentrates in certain areas, causing them to cool significantly, while other areas, lacking fresh air, accumulate heat and remain warm. In hot summer weather, this can result in localized temperatures exceeding the optimal temperature range for chickens, while areas with fresh air may remain too cold, creating uneven heating and cooling within the chicken house. Utility Model Content

[0004] The purpose of this utility model is to provide a fresh air device for chicken coop ventilation, so as to solve the problem mentioned in the background art that the current fresh air devices on the market cannot evenly guide fresh air into the chicken coop.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fresh air device for chicken coop ventilation, comprising a chicken coop body, three air inlets on one side of the chicken coop body, each air inlet equipped with a ventilator, and three air outlets on the other side of the chicken coop body, each air outlet equipped with an activated carbon filter plate; three rows of support frames are provided inside the chicken coop body, each of the three rows of support frames is rotatably connected to a rotating shaft, one end of each of the three rows of rotating shafts is equipped with an air guide plate, support plates are provided between the two ends of the three middle support frames, and a reduction gearbox is provided between each support plate, the output shafts of the three ventilators are respectively located inside the three reduction gearboxes, the other end of each of the three reduction gearboxes is equipped with a rotating column, one end of the rotating column is equipped with a drive assembly for driving the air guide plate to swing, and one end of the rotating shaft is equipped with a cleaning assembly for cleaning the filter screen at the input end of the ventilator.

[0006] Preferably, the drive assembly includes three limiting plates respectively disposed at one end of the three rotating columns, and each of the three limiting plates is slidably connected to a limiting column inside the other end. Each of the three limiting columns is provided with a sliding sleeve at one end, and each of the three sliding sleeves is slidably connected to a rotating rod. Each of the three rotating rods is provided with a connecting plate at both ends, and the six connecting plates are respectively connected to the outer surfaces of both ends of the three rotating shafts.

[0007] Preferably, the cleaning assembly includes three movable shafts rotatably connected inside the chicken coop body. One end of the three movable shafts and one end of the three lower rotating shafts are respectively provided with mutually meshing first bevel gears. Three rows of first support bars are provided on the outside of the chicken coop body. Three scrapers are slidably connected between the three rows of first support bars. Threaded rods threaded inside the scrapers are also rotatably connected between the three rows of first support bars. Each of the three threaded rods has a connecting post at its bottom, and one end of the three connecting posts and the other end of the three movable shafts are respectively provided with mutually meshing second bevel gears.

[0008] Preferably, the outer side of the chicken coop body is also provided with three rows of second support bars, and each of the three rows of second support bars is provided with a limiting rod that is slidably connected inside the scraper.

[0011] Preferably, the three scrapers in the three rows are evenly distributed, and the end of the scraper that is in contact with the fan is made of an elastic material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By using the air intake plate on the support frame, the fresh air is guided into the chicken house. A large amount of harmful gases, such as ammonia and hydrogen sulfide, will be generated inside the chicken house. The air intake plate can introduce fresh air into the chicken house, dilute and discharge these harmful gases in time, keep the air inside the chicken house fresh, and reduce the growth and spread of pathogens inside the chicken house.

[0014] (2) By setting the drive components, the effect of driving the air intake plate to swing is achieved, so that it can guide the fresh air evenly. The fresh air can flow in the chicken house from multiple angles and in all directions, and can continuously change the direction of the fresh air flow, avoid the occurrence of ventilation dead corners, and allow fresh air to reach all areas of the chicken house. This increases the contact area and mixing degree between the fresh air and harmful gases, so that the harmful gases can be diluted and discharged from the chicken house in time, effectively reducing the concentration of harmful gases in the chicken house and improving air quality.

[0015] (3) By setting up the cleaning components, the filter screen at the input end of the ventilator is cleaned, which can maintain the permeability of the filter screen and ensure that the ventilator can continuously draw in fresh air into the chicken house with a stable flow rate, maintain good ventilation in the chicken house, and avoid the decline in air quality in the chicken house due to poor ventilation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution: a fresh air device for chicken coop ventilation.

[0025] Example 1: As Figures 1-4 and Figure 6 As shown, the air intake plate 5 and drive assembly can uniformly guide the fresh air. The chicken house body 1 has three air inlets on one side, each equipped with a ventilator 2. The chicken house body 1 also has three air outlets on the other side, each equipped with an activated carbon filter plate 19 (e.g., ...). Figure 1 , Figure 3 and Figure 4 As shown), the chicken coop body 1 has three rows of support frames 3 inside, and each of the three rows of support frames 3 is rotatably connected to a rotating shaft 4. One end of each of the three rotating shafts 4 is equipped with a draft fan 5 (as shown). Figure 3 and Figure 4 As shown), the three support frames 3 in the middle are provided with support plates at both ends, and a reduction gearbox 6 is provided between each support plate. The output shafts of the three fans 2 are respectively located inside the three reduction gearboxes 6. The other end of the three reduction gearboxes 6 is provided with a rotating column 7. One end of the rotating column 7 is provided with a driving assembly for driving the air-guiding plate 5 to swing. The driving assembly includes three limiting plates 8 respectively located at one end of the three rotating columns 7. The other end of the three limiting plates 8 is slidably connected to the limiting column 9. One end of the three limiting columns 9 is provided with a sliding sleeve 10. The three sliding sleeves 10 are slidably connected to the rotating rod 11. Both ends of the three rotating rods 11 are provided with connecting plates 12. The six connecting plates 12 are respectively connected to the outer surfaces of both ends of the three rotating shafts 4. The three activated carbon filter plates 19 and the three air outlets are equidistantly distributed, and the three air outlets and the three air inlets are symmetrically arranged. One end of each of the three rows of air-guiding plates 5 is provided with a rotating seat, and the rotating seat is rotatably connected to a connecting rod 20 (such as...). Figure 3 and Figure 4 (As shown).

[0026] After the ventilation fan 2 is started, fresh air from the outside is drawn into the chicken coop body 1. The operation of the ventilation fan 2 also drives the three rotating columns 7 to rotate. The rotation of the three rotating columns 7 drives the limiting plate 8 to rotate, thereby causing the limiting column 9 to slide inside the limiting plate 8. Subsequently, under the action of the limiting column 9, the sliding sleeve 10 slides on the outer surface of the rotating rod 11, thus converting the circular motion of the rotating column 7 into the reciprocating oscillation of the rotating rod 11 (e.g., Figure 6 As shown), the connecting plates 12 at both ends of the rotating rod 11 are connected to the rotating shaft 4. The reciprocating swing of the rotating rod 11 drives the rotating shaft 4 to rotate within the support frame 3. The rotation of the rotating shaft 4 causes the air-guiding plates 5 mounted on it to swing accordingly. The swinging of the three air-guiding plates 5 will also affect the connecting rod 20 (as shown). Figure 3 and Figure 4 Under the action of (as shown), it drives the three upper air-guiding plates 5 and the three lower air-guiding plates 5 to swing simultaneously, thereby uniformly guiding the fresh air, while the reduction gearbox 6 (as shown) Figure 6 (As shown) The power from the output shaft of the ventilator 2 is decelerated to achieve stable oscillation of the air intake plate 5. The activated carbon filter plate 19 can filter dust, debris, etc. from the air, preventing external impurities from entering the chicken house. At the same time, it can also reduce the diffusion of odors inside the chicken house body 1 to a certain extent, and adsorb odors and impurities (such as... Figure 1 , Figure 3 and Figure 4 As shown), the three air outlets and three air inlets are symmetrically arranged (as shown). Figure 4 As shown in the figure, a good air circulation channel is formed, which ensures the effective exchange of air in the chicken house body 1.

[0027] Example 2: Figures 2-5 As shown, unlike Embodiment 1, the cleaning assembly can clean the filter screen on the ventilator 2. One end of the rotating shaft 4 is equipped with a cleaning assembly for cleaning the filter screen at the input end of the ventilator 2. The cleaning assembly includes three movable shafts 13 rotatably connected inside the chicken coop body 1. One end of each of the three movable shafts 13 and one end of the three rotating shafts 4 located below are respectively provided with meshing first bevel gears 14. Three rows of first support bars 15 are provided on the outside of the chicken coop body 1, and three scrapers 16 (such as...) are slidably connected between each of the three rows of first support bars 15. Figures 2-5 As shown), the three rows of first support bars 15 are rotatably connected to threaded rods threaded inside scraper 16, and each of the three threaded rods has a connecting post at its bottom. One end of each of the three connecting posts and the other end of each of the three movable shafts 13 are respectively provided with mutually meshing second bevel gears 17. The outer side of the chicken coop body 1 is also provided with three rows of second support bars 18, and each of the three rows of second support bars 18 is provided with a limiting rod slidably connected inside scraper 16. The three scraper blades 16 in the three rows are equidistantly distributed (e.g., ...). Figures 2-5As shown in the figure, the end of the scraper 16 that is attached to the fan 2 is made of elastic material.

[0028] When the rotating shaft 4 rotates, it will also drive the movable shaft 13 to rotate under the action of the first bevel gear 14 (e.g. Figure 5 (As shown), then under the action of the second bevel gear 17, it drives the connecting column and the threaded rod to rotate. Then, under the action of the limit rod, it drives the scraper 16 to rise and fall. When the scraper 16 rises and falls, the end that is in contact with the filter screen at the input end of the fan 2 will clean the filter screen (such as...). Figures 2-5 As shown in the figure, the elastic material can better adapt to the surface shape of the filter, fit the filter tightly, and effectively scrape away the dust and debris accumulated on the filter, ensuring the filter's permeability.
