Description

Technical Field

[0001] This utility model relates to the field of sheepfold ventilation technology, specifically to a pre-filtered and purified air duct for sheepfold ventilation. Background Technology

[0002] In modern animal husbandry, ventilation and air duct design in sheep pens are key factors in ensuring the health and productivity of sheep. A well-designed ventilation system can effectively regulate temperature, humidity, and air quality within the sheep pen, reducing the accumulation of harmful gases and lowering the incidence of respiratory diseases. A scientifically designed air duct layout ensures even airflow distribution, preventing localized discomfort and providing a comfortable growing environment for the sheep, thereby improving farming efficiency.

[0003] Utility model patent CN202121304760.3 discloses a ventilation device for sheep pens. This device includes a sheep pen with ventilation openings on both sides. Ventilation windows are located on the outer side of the sheep pen at the ventilation openings. The ventilation windows are mounted on guide rails and are opened and closed by a traction mechanism. The traction mechanism includes a drive motor, an upper fixed plate, a lower fixed plate, a first transmission screw, a second transmission screw, a first transmission belt, a second transmission belt, a traction frame, a guide rod, and a support connecting rod. When ventilation is needed, the drive motor connects to the first transmission belt and... The second conveyor belt drives the first and second transmission screws to rotate, causing the traction frame, support rod, and ventilation window to rise. This prevents the ventilation window from sealing the vent, allowing for convection ventilation. When ventilation is not needed, the drive motor drives the first and second transmission screws to rotate via the first and second conveyor belts, causing the traction frame, support rod, and ventilation window to fall, sealing the vent. This stops the convection ventilation. The traction mechanism enables rapid ventilation of the sheepfold without requiring manual opening or closing of the ventilation windows, reducing the workload of operators and increasing the ventilation efficiency of the sheepfold.

[0004] Although the sheepfold ventilation system improves ventilation efficiency, it has several drawbacks in practical use: Ventilation is achieved through unfiltered airflow into the sheepfold, leading to the entry of large amounts of dust, particulate matter, and other pollutants. These pollutants accumulate, reducing air quality and potentially severely impacting the sheep's respiratory system, increasing the incidence of respiratory diseases. Prolonged exposure to such an environment threatens the sheep's health, affecting their growth, development, and productivity. Therefore, we propose a pre-filtered and purified air duct for sheepfold ventilation. Utility Model Content

[0005] The purpose of this invention is to provide a pre-filtered and purified air duct for sheepfold ventilation, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The pre-filtered purification air duct for sheep pen ventilation includes an air inlet hood installed on the outer wall of the sheep pen. The rear end of the air inlet hood is open and connected to the interior of the sheep pen. A fan is installed at the front end of the air inlet hood, and an air duct is installed at the air inlet of the fan. A filter is installed at the front end of the air duct.

[0008] The filter unit includes a hollow shell that is connected to the air duct. Multiple slots are provided on the right end face of the shell. An air inlet duct is installed at the front end of the shell. Attachment brackets are inserted into the slots, and dust filters are fixed inside the openings of the attachment brackets. An outer plate is provided between the right ends of the multiple attachment brackets. Limiting components are installed on both the front and rear sides of the right end face of the shell, located on the outer plate.

[0009] Preferably, the limiting component includes a box body fixedly connected to the outer wall of the housing. The box body has a hollow structure inside. Two guide rods are fixed inside the box body, and a slider is slidably installed between the two guide rods. A spring is sleeved on the outside of the guide rods to abut against the slider. A limiting plate is fixed to the right end of the slider. The front and rear ends of the limiting plate pass through the outer wall of the box body and are slidably connected to the box body. One end of the limiting plate protrudes to the right side of the outer plate and abuts against the outer wall of the outer plate.

[0010] Preferably, the air inlet pipe is ring-shaped and a baffle is installed at the air inlet pipe.

[0011] Preferably, a lever is fixed to the outer wall of the limiting plate near the end edge, and the cross-sectional shape of the lever is a right trapezoid.

[0012] Preferably, a limiting block is fixed at the right end of the insert, and multiple limiting grooves are opened on the left end face of the outer plate. The bottom end of the limiting groove is closed, and the limiting block is inserted into the corresponding limiting groove.

[0013] Preferably, the cross-sectional shape of the insert is U-shaped, and the insert and the dust filter are fixedly connected by bolts.

[0014] Preferably, a plate is fixedly connected to the opening of the air inlet hood by bolts, and multiple air holes are provided on the outside of the plate in a matrix distribution.

[0015] Preferably, the slider and the limiting plate are integrally formed, and the slider is perpendicular to the limiting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The design incorporates an air inlet hood, fan, ductwork, and filter: when the fan is started, external airflow enters the housing. As the airflow passes through multiple dust filters, dust and other particulate matter in the airflow are intercepted and filtered. The filtered airflow then enters the sheepfold directly through the ductwork and air inlet hood. This design ensures efficient ventilation in the sheepfold while preventing external dust and other impurities from entering, thus guaranteeing air quality inside the sheepfold and protecting the health of the sheep.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] This embodiment provides a technical solution:

[0032] Please see Figures 1-6 As shown, the pre-filtering and purification air duct for sheep pen ventilation includes an air inlet hood 2 installed on the outer wall of sheep pen 1. The rear end face of the air inlet hood 2 is open and connected to the interior of sheep pen 1. A fan 3 is installed at the front end of the air inlet hood 2. An air duct 4 is installed at the air inlet of the fan 3. A filter section 5 is installed at the front end of the air duct 4. The filter section 5 includes a hollow shell 50 and is connected to the air duct 4. Multiple slots 500 are provided on the right end face of the shell 50. An air inlet pipe 51 is installed at the front end of the shell 50. A bracket 52 is inserted into the slot 500, and a dust filter 520 is fixed in the opening of the bracket 52. An outer plate 53 is provided between the right ends of the multiple brackets 52.

[0033] Furthermore, limiting components are installed on both the front and rear sides of the outer plate 53 on the right end face of the housing 50. The limiting components include a box 54 fixedly connected to the outer wall of the housing 50. The box 54 has a hollow interior structure, with two guide rods 55 fixed inside. A slider 57 is slidably installed between the two guide rods 55, and a spring 56 is sleeved on the outside of the guide rods 55 to press against the slider 57. A limiting plate 58 is fixed to the right end of the slider 57. The front and rear ends of the limiting plate 58 pass through the outer wall of the box 54 and are slidably connected to the box 54, with one end of the limiting plate 58 protruding to the right side of the outer plate 53 and pressing against the outer wall of the outer plate 53. The limiting components effectively fix and limit the outer plate 53, preventing it from disengaging from the slot 500. Simultaneously, the guide rods 55, springs 56, and limiting plates 58 facilitate adjustment of the position of the limiting plate 58, thus facilitating the assembly and disassembly of the outer plate 53.

[0034] In this embodiment, the air inlet duct 51 is ring-shaped, and a baffle 510 is installed at the air inlet duct 51. This design effectively expands the air intake area while blocking large particles from entering, ensuring clean air in the sheepfold and reducing the impact of dust on the health of the sheep.

[0035] In this embodiment, a lever 580 is fixed to the outer wall of the limiting plate 58 near its end edge. The lever 580 has a right-angled trapezoidal cross-section. The right-angled trapezoidal cross-section of the lever 580 facilitates user operation and enhances the ease of adjustment of the limiting plate 58.

[0036] In this embodiment, a limiting block 521 is fixed to the right end of the insert 52, and multiple limiting grooves 530 are provided on the left end face of the outer plate 53. The bottom end of the limiting groove 530 is closed, and the limiting block 521 is inserted into the corresponding limiting groove 530. The insertion and engagement of the limiting block 521 and the limiting groove 530 achieves precise positioning of the insert 52, preventing it from shifting during use and ensuring the stability and filtration effect of the dust filter 520; at the same time, this design improves the ease of disassembly and assembly of the insert 52.

[0037] In this embodiment, the insert 52 has a U-shaped cross-section, and the insert 52 is fixedly connected to the dust filter 520 by bolts. The U-shaped insert 52 is fixed to the dust filter 520 by bolts, which is simple and stable in structure, easy to disassemble and clean, extends the service life of the dust filter, and reduces maintenance costs.

[0038] In this embodiment, a plate 20 is fixedly connected to the opening of the air inlet hood 2 by bolts, and multiple air holes 200 arranged in a matrix are provided on the outside of the plate 20. The matrix-arranged air holes 200 on the plate 20 optimize the airflow distribution, ensure uniform air intake, and improve the ventilation effect in the sheepfold.

[0039] In this embodiment, the slider 57 and the limiting plate 58 are integrally formed, with the slider 57 perpendicular to the limiting plate 58. This design enhances the overall strength and stability of the slider 57 and the limiting plate 58, ensuring their service life and the limiting effect on the outer plate 53.

[0040] Understandably, the outer wall of sheepfold 1 is provided with a connecting groove, which is connected to the air inlet hood 2. This design allows the airflow from the outside to enter the sheepfold through the air inlet hood 2 and the connecting groove, thus ensuring the smooth flow of air.

[0041] It is worth noting that the fan 3 involved in this embodiment is a conventional technology and will not be described in detail here.

[0042] In actual use, the user first connects the power supply of the ventilator 3, and the ventilator 3 starts to work. At this time, the outside airflow enters the housing 50 through the air inlet pipe 51. When the airflow passes through multiple dust filters 520, the dust and other particles in the airflow are intercepted and filtered. The filtered airflow enters the air duct 4 and enters the air inlet hood 2 through the ventilator 3. Finally, the airflow is blown into the sheepfold 1 through multiple air holes 200.

[0043] When it is necessary to remove the insert 52 to clean the dust filter 520, the user first pushes the lever 580 from the middle to both sides. The lever 580 causes the limiting plate 58 to move horizontally. The limiting plate 58 then causes the slider 57 to slide along the guide rod 55. At the same time, the spring 56 is compressed by the slider 57. When the end of the limiting plate 58 retracts into the box 54, the user pushes the outer plate 53 to the right. The outer plate 53 then causes multiple inserts 52 to slide along the slot 500. When the insert 52 is disengaged from the slot 500, the user lifts the insert 52 upwards. The limiting block 521 then slides along the limiting groove 530. When the limiting block 521 is disengaged from the limiting groove 530, the insert 52 is disassembled. Finally, the user can clean the dust filter 520.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
