Description

Technical Field

[0001] This utility model relates to the field of ventilation engineering technology, and in particular to a ventilation device for cattle and sheep pens. Background Technology

[0002] In the current cattle and sheep breeding sector, traditional livestock pens have many problems. Traditional livestock pens have poor ventilation and heat dissipation. Ordinary exhaust fans are cumbersome to install, dismantle, and maintain. Under the pen-raising model, cattle and sheep manure produces a large amount of harmful gases such as ammonia and breeds bacteria. Existing pens lack sufficient air circulation devices, making it difficult to ensure the health of cattle and sheep. Some pens lack filtration devices during ventilation, polluting the outdoor environment. In cold northern regions, the contradiction between maintaining the indoor temperature and ventilation needs in livestock pens during winter is prominent, affecting the growth and production performance of cattle and sheep. Existing ventilation devices are mostly installed on the side walls of the pens, resulting in poor air circulation in the middle of the pens and failing to evenly and effectively improve air quality. These problems urgently require more scientific and reasonable ventilation devices for cattle and sheep pens to solve.

[0003] Existing technologies for ventilation systems in cattle and sheep pens encompass natural ventilation, mechanical ventilation, and intelligent ventilation systems. Natural ventilation relies on the building structure and natural wind pressure, with thermal pressure driving airflow. Mechanical ventilation includes negative pressure, positive pressure, and hybrid systems. Negative pressure ventilation uses fans to exhaust air and introduce fresh air, while positive pressure ventilation uses fans to pressurize and deliver air, and exhausts it through vents. Hybrid systems combine both and dynamically adjust according to temperature and humidity. Intelligent ventilation systems use sensors to collect environmental data, which is then processed by a controller, and the actuators adjust the ventilation equipment. Furthermore, energy-saving ventilation technologies such as ground source heat pump auxiliary systems and solar-powered systems further enhance ventilation efficiency, creating a comfortable growing environment for cattle and sheep.

[0004] Traditional ventilation equipment for cattle and sheep pens does not remove dust from the air during ventilation, allowing a large amount of dust and impurities to enter the pens, polluting the environment. This not only affects the health of livestock and poultry but also increases labor costs. Therefore, a new ventilation device for cattle and sheep pens is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ventilation device for cattle and sheep pens, which aims to improve the existing ventilation devices that lack dustproof design, which may cause a series of problems in cattle and sheep pens, including livestock health, equipment wear and tear, and environmental degradation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ventilation device for cattle and sheep pens, comprising a base, a storage bin fixedly connected to the top of the base, a discharge pipe fixedly connected to the top of the storage bin, a distribution bucket fixedly connected to the top of the discharge pipe, an inverted pear-shaped cylinder fixedly connected to one end of the distribution bucket, a spiral blade fixedly connected inside the inverted pear-shaped cylinder, a pre-filter fixedly connected to the other end of the inverted pear-shaped cylinder, a high-efficiency filter fixedly connected inside the pre-filter, and a round tube clamping assembly installed on the top of the base;

[0007] As a further description of the above technical solution: the round tube clamping assembly includes two support columns, a cylinder is installed on the top of the two support columns, a fixed column is fixedly connected to the driving end of the cylinder, a connecting plate is rotatably connected to both sides of the fixed column, a round tube clamp is fixedly connected to the outside of the fixed column, and a connecting column is fixedly connected to the middle of the round tube clamp.

[0008] As a further description of the above technical solution: the other end of the cylinder is also fixedly connected to a fixing column, and the other ends of the two connecting plates are fixedly connected to both sides of the fixing column;

[0009] As a further description of the above technical solution: a carbon filter is fixedly connected inside the high-efficiency filter screen, and an exhaust port is fixedly connected to the outside of the dispensing hopper;

[0010] As a further description of the above technical solution: ventilation ducts are fixedly connected inside the two circular tube clamps, and the pre-filter is fixedly connected to the outside of the ventilation ducts.

[0011] As a further description of the above technical solution: the ventilation duct is internally fixedly connected to a mounting shaft, and the mounting shaft is internally fixedly connected to a mounting plate;

[0012] As a further description of the above technical solution: the top of the storage silo is fixedly connected to the bottom of the ventilation duct, and a fan is fixedly connected to the outside of the mounting plate;

[0013] As a further description of the above technical solution: both sides of the two fixed columns are fixedly connected to fixed plates, and the tops of the two round tube clamps are fixedly connected to two positioning columns.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model,

[0016] The fan drives the pre-filter, high-efficiency filter, and carbon filter to work, allowing gas to enter the inverted pear-shaped cylinder. The spiral blades inside the cylinder guide the gas flow, causing it to rotate and generate centrifugal force, which in turn drives the distribution bin to work, achieving dust and gas separation and ultimately achieving dust removal.

[0017] 2. In this utility model, the linkage structure of the cylinder, the fixed column, the round pipe clamp and the connecting plate enables the automatic clamping action of the double clamps retracting inward synchronously through mechanical drive during the installation of the ventilation duct. This solves the problems of cumbersome positioning, low fixing accuracy and insufficient operation efficiency in the traditional manual installation process, thereby simplifying the installation process and improving installation stability and construction efficiency.

[0024] 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.

[0025] Reference Figures 1 to 3This utility model provides an embodiment of a ventilation device for cattle and sheep pens, comprising a base 1, which is welded from high-strength steel and has anti-slip textures on the bottom to stably support the entire ventilation device and prevent it from shaking on the pen floor. A storage bin 2 is fixedly connected to the top of the base 1. The storage bin 2 is a cylindrical container with an inner lining to prevent dust from flying, used to collect dust separated during ventilation and to centrally store dust removal waste. A discharge pipe 3 is fixedly connected to the top of the storage bin 2, and a distribution bin 22 is fixedly connected to the top of the discharge pipe 3. The discharge pipe 3 has an inclined pipe structure with a gradually decreasing diameter, which allows the dust separated by the distribution bin 22 to be separated by gravity. The material is smoothly introduced into the storage bin 2 to avoid dust accumulation and blockage. The distribution bin 22 is a hollow cylindrical structure, which forms a separation space between dust and gas inside. Its bottom is connected to the discharge pipe 3 to ensure that the separated dust can fall quickly. One end of the distribution bin 22 is fixedly connected to an inverted pear-shaped cylinder 4. The inside of the inverted pear-shaped cylinder 4 is fixedly connected to a spiral blade 6. The diameter of the inverted pear-shaped cylinder 4 gradually decreases from one end connected to the distribution bin 22 to the other end. This special shape can work with the spiral blade 6 to form a stable rotating flow field for the gas. The spiral blade 6 is spirally wrapped around the inner wall of the cylinder. When the gas passes through, it can guide the gas and make it spiral upward along the axis of the cylinder.

[0026] A pre-filter 7 is fixedly connected to the other end of the inverted pear-shaped cylinder 4. The pre-filter 7 is made of coarse-pore metal mesh, which can pre-filter larger particles in the air, reducing the load on subsequent filter components. A high-efficiency filter 8 is fixedly connected inside the pre-filter 7. The high-efficiency filter 8 uses HEPA filter material, which can effectively intercept dust particles in the air and improve the air purification accuracy. A carbon filter 9 is fixedly connected inside the high-efficiency filter 8. The carbon filter 9 is filled with activated carbon particles. Utilizing the adsorption properties of activated carbon, it removes odor gases such as ammonia and hydrogen sulfide from the air, improving the air quality in the enclosure. An exhaust vent 5 is fixedly connected to the outside of the distribution hopper 22. A ventilation duct 10 is fixedly connected to the outside of the exhaust vent 5. After dust removal... The deodorized clean air is discharged from here, providing fresh circulating air for the enclosure. A round tube clamping assembly is installed on the top of the base 1, and a cylinder 15 is installed on the top of the two support columns 14. The round tube clamping assembly is used to fix the ventilation duct 10. A fixed column 16 is fixedly connected to the drive end of the cylinder 15. A round tube clamp 18 is fixedly connected to the outside of the fixed column 16. When the ventilation duct 10 needs to be installed, the cylinder 15 drives the fixed column 16 to move outward. The fixed column 16 drives the round tube clamp 18 to move through the linkage mechanism. When the fixed column 16 moves outward, it drives the round tube clamp 18 to rotate inward. The round tube clamp 18 has an arc-shaped clamp structure and an anti-slip rubber pad on the inner side, which can tightly fit the outer wall of the ventilation duct 10.

[0027] Both sides of the fixed column 16 are rotatably connected to connecting plates 19. When the round pipe clamps 18 rotate inward, they drive the connecting plates 19 to move outward. The connecting plates 19 play a transmission role, so that the round pipe clamps 18 on both sides move synchronously. When the connecting plates 19 move outward, they drive the bottom of the round pipe clamps 18 on the other side to rotate inward. The two round pipe clamps 18 form a clamping structure, retract inward and grip the ventilation duct 10, thereby completing the installation of the ventilation duct 10. This clamping method can quickly fix pipes of different diameters and has good stability.

[0028] Reference Figures 2 to 4 The cylindrical tube clamping assembly includes two support columns 14, which are vertically and firmly fixed on the mounting base, providing a solid support foundation for the entire clamping assembly. These columns can withstand large external forces without shaking, ensuring the stability of the clamping action. The cylinder 15 is a double-acting cylinder type. By precisely controlling the magnitude and direction of the air pressure, it can achieve stable and efficient linear reciprocating motion, providing a reliable and powerful power source for the action of the entire clamping assembly. The fixed column 16, as a key force transmission component, has a surface that has undergone special hardening treatment, giving it good wear resistance and pressure resistance. It can transmit the driving force generated by the cylinder 15 to the subsequent execution components without loss.

[0029] The connecting plate 19 is connected to the fixed column 16 via a hinged connection. This connection method not only ensures that the connecting plate 19 can flexibly change its angle when the fixed column 16 moves, but also ensures good stability during force transmission, thereby driving the grippers on both sides to move synchronously. The round pipe gripper 18 is designed with an arc-shaped encircling structure, and its inner surface is also provided with an anti-slip rubber pad to increase the friction between it and the ventilation duct 10. When it contracts inward under force, it can tightly fit against the outer wall of the pipe, providing reliable clamping force and preventing the pipe from shifting during installation. A connecting post 20 is fixedly connected to the middle of the claw 18. The connecting post 20 passes through the middle of the cylindrical claw 18, rigidly connecting the left and right claw structures into a whole. During the clamping process, it can ensure the synchronicity and stability of the two claws, so that the clamping force is evenly distributed and the ventilation duct 10 is not damaged due to uneven force. The other end of the cylinder 15 is also fixedly connected to a fixing post 16. The fixing post 16 and the driving end fixing post 16 form a symmetrical structure and together constitute the double fulcrum of the clamping action. This symmetrical design can balance the force during the clamping process, making the clamping action more stable and reliable.

[0030] The other ends of the two connecting plates 19 are fixedly connected to both sides of the fixed column 16. Through the linkage of the connecting plates 19, the lever principle is cleverly utilized so that the two round tube clamps 18 can accurately form opposite or opposite movements under the drive of the fixed column 16, realizing precise clamping and releasing of the ventilation duct 10. The ventilation duct 10 is fixedly connected inside the two round tube clamps 18. When the round tube clamps 18 retract inward, their inner walls tightly fit the outer walls of the ventilation duct 10, forming a firm connection, ensuring that the ventilation duct 10 will not loosen or fall off during subsequent use, thus enabling the ventilation duct 10 to be installed and work stably. The pre-filter 7 is fixedly connected to the outside of the ventilation duct 10. The pre-filter 7 is made of multiple layers of metal mesh with different pore sizes. The mesh size is carefully designed to initially intercept larger particulate impurities in the gas, such as hair and debris, effectively reducing the filtration burden of the subsequent high-efficiency filter 8 and carbon filter 9, and extending the service life of the entire filtration system.

[0031] Reference Figures 1 to 3 The ventilation duct 10, serving as the key transmission channel for the entire ventilation system, has an internally fixedly connected mounting shaft 11. An internally fixedly connected mounting plate 12 is also connected to the mounting shaft 11, and an externally fixedly connected fan 13 is attached to the mounting plate 12. The mounting shaft 11 is made of high-strength alloy material, providing stable support for the installation of subsequent components due to its excellent mechanical properties. Even under the strong vibrations generated by the high-speed operation of the fan 13, it ensures the stability of all components during operation, preventing loosening or displacement due to vibration, thus guaranteeing the reliable operation of the ventilation system. The mounting plate 12 undergoes precision machining, resulting in a highly flat surface, providing a reliable carrier for the installation of the fan 13. Its special threaded hole design perfectly matches the mounting feet of the fan 13, and the connection is secured with high-strength bolts, ensuring not only the airflow... The fan 13 can work stably and effectively disperse the stress generated during its operation, ensuring that the fan 13 remains balanced during high-speed operation and achieving efficient ventilation. It continuously introduces fresh air into the cattle and sheep pens. The top of the storage bin 2 is fixedly connected to the bottom of the ventilation duct 10. The storage bin 2 has a large volume, and its conical bottom design can effectively prevent dust accumulation and blockage. During the ventilation and dust removal process, the storage bin 2 is used to receive the dust separated from the ventilation duct 10. Through a clever airflow guidance design, the dust falls smoothly into the bottom of the storage bin 2 under the action of gravity, while the clean gas that has been treated by dust removal continues to be discharged upwards, ensuring that the gas after dust removal can be discharged cleanly, effectively improving the environment of the cattle and sheep pens, reducing the harm of dust to the health of cattle and sheep, and reducing the probability of respiratory diseases.

[0032] The fan 13 is driven by a high-performance motor, and its blades are aerodynamically optimized. After starting, it generates a strong gravitational force, forming a stable airflow channel. This gravitational force causes the gas to pass through the pre-filter 7, the high-efficiency filter 8, and the carbon filter 9, which sequentially filter and adsorb large particulate impurities, fine dust, and odor molecules in the gas. The gas then enters the inverted pear-shaped cylinder 4, thus starting the entire ventilation and dust removal process and providing a fresh and healthy air environment for cattle and sheep pens. Fixing plates 17 are fixedly connected to both sides of the two fixed columns 16. The fixing plates 17 are made of thickened steel plates and are firmly connected to the fixed columns 16 through welding, forming a stable triangular structure, which greatly enhances the structural strength of the fixed columns 16. Driven by the cylinder 15, even under large forces, the fixing plates 17 can effectively prevent the fixed columns 16 from deforming, so that they can stably drive the circular tube clamp 18 to move, ensuring the reliability of the fixing structure during the installation of the ventilation duct 10.

[0033] Two positioning posts 21 are fixedly connected to the top of each of the two round tube clamps 18. The positioning posts 21 adopt a high-precision cylindrical structure and fit with the positioning holes on the top of the round tube clamps 18 with extremely high precision. When installing the ventilation duct 10, the positioning posts 21 provide precise positioning and guidance for the rotation of the round tube clamps 18. Through a precise mechanical transmission design, it is ensured that when the round tube clamps 18 retract inward to grip the ventilation duct 10, they can move smoothly along a predetermined trajectory, ensuring accurate operation and guaranteeing the accuracy and firmness of the installation of the ventilation duct 10, avoiding problems such as air leakage caused by installation deviation.

[0034] Working principle: When ventilation is needed in cattle and sheep pens, the gas is drawn by the fan 13 through the pre-filter 7, high-efficiency filter 8 and carbon filter 9 into the inverted pear-shaped cylinder 4. The inverted pear-shaped cylinder 4 is equipped with spiral blades 6, which guide the gas flow. The gas rotates in the inverted pear-shaped cylinder 4 after being guided by the spiral blades 6. The rotation generates centrifugal force, which separates the dust from the gas in the distribution bin 22. The dust enters the storage bin 2 through the discharge pipe 3 at the bottom of the distribution bin 22, thus achieving the dust removal effect and improving the environment of the cattle and sheep pens.

[0035] When the ventilation duct 10 needs to be installed, the cylinder 15 drives the fixing column 16 to move outward. When the fixing column 16 moves outward, it drives the round pipe clamp 18 to rotate inward. When the round pipe clamp 18 rotates inward, it drives the connecting plate 19 to move outward. When the connecting plate 19 moves outward, it drives the bottom of the round pipe clamp 18 on the other side to rotate inward. The two round pipe clamps 18 retract inward and grip the ventilation duct 10, thereby completing the installation of the ventilation duct 10.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
