Description

Technical Field

[0001] This utility model relates to the field of environmental control in animal husbandry, and in particular to an automatic ventilation switching device for a pasture ventilator. Background Technology

[0002] The main purposes and significance of using ventilation fans in pastures are as follows: First, ventilation fans effectively improve air quality, expelling harmful gases such as ammonia and hydrogen sulfide from the barn, introducing fresh air, reducing the occurrence of respiratory diseases, and protecting livestock health. Second, they help regulate temperature and humidity within the pasture. Furthermore, good ventilation keeps the pasture environment dry, inhibits the growth of bacteria and parasites, creates a comfortable living environment for livestock, and improves production performance and breeding efficiency.

[0003] Pasture ventilation fans primarily utilize motors to drive blades, propelling airflow and facilitating air exchange between indoors and outdoors. In summer, fans accelerate the expulsion of hot air and introduce cool outside air, lowering the temperature inside the barn and preventing stress in livestock. In winter, they control ventilation volume, expelling humid and polluted air while preventing cold air from directly blowing onto livestock, maintaining suitable temperature, humidity, and air quality. In farrowing pens, fans provide a good air environment for mothers and young animals, reducing disease incidence; in fattening pens, they promote livestock growth and improve feed conversion rates. In short, ventilation fans play a crucial role in improving the pasture environment in different seasons and farming scenarios.

[0004] In existing technologies, some ranch ventilation fans only rely on installed fans for ventilation. However, the size of the enclosure cannot be adjusted during ventilation, resulting in uncontrolled ventilation levels. Over-ventilation can lead to excessive temperature differences between indoors and outdoors, potentially causing livestock to catch colds and other illnesses. Insufficient ventilation, on the other hand, can result in excessive humidity, which promotes the growth of bacteria. Therefore, an automatic ventilation switching device for ranch ventilation fans is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic ventilation switching device for ranch ventilators, which aims to improve the problem of uncontrolled ventilation levels in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic ventilation switching device for a ranch ventilator includes a fixed plate. A detachable component for removing a filter screen is installed on the inner wall of the fixed plate. A fixed ring is fixedly connected to the inner wall of the fixed plate. Multiple connecting plates are fixedly connected to the inner wall of the fixed ring. A connecting ring is fixedly connected to the other end of each of the multiple connecting plates. Sliding columns are slidably connected to the inner walls of each of the multiple connecting plates. Opening and closing plates are fixedly connected to the bottom ends of each of the multiple sliding columns. Rotating plates are rotatably connected to the bottom of each of the multiple opening and closing plates. A motor is fixedly connected to the inner wall of the fixed plate, and a gear is fixedly connected to the drive end of the motor.

[0008] As a further description of the above technical solution:

[0009] The detachable component includes a mounting shell, a pressing rod slidably connected to the inner wall of the mounting shell, a wedge block fixedly connected to one end of the pressing rod, a plurality of return springs fixedly connected to the inner wall of the fixing plate, a limit ball fixedly connected to the other end of each of the plurality of return springs, and an elastic spring sleeved on the outer wall of the pressing rod.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the rotating plate is provided with multiple sliding grooves, and the bottoms of the multiple opening and closing plates are respectively slidably connected to the inner wall of the multiple sliding grooves;

[0012] As a further description of the above technical solution:

[0013] A toothed ring is fixedly connected to the outer wall of the sliding groove, and the outer wall of the sliding groove is rotatably connected to the inner wall of the fixed ring.

[0014] As a further description of the above technical solution:

[0015] The inner walls of the multiple connecting plates are provided with sliding grooves, and the outer walls of the multiple sliding columns are slidably connected to the inner walls of the multiple sliding grooves;

[0016] As a further description of the above technical solution:

[0017] The outer wall of the gear and the outer wall of the gear ring are meshed with each other, and a ventilation fan is installed on the inner wall of the fixing plate;

[0018] As a further description of the above technical solution:

[0019] The outer wall of the mounting shell is provided with multiple limiting holes, and the outer walls of the multiple limiting balls are slidably connected to the inner walls of the multiple limiting holes. One end of the elastic spring is fixedly connected to the outer wall of the wedge block, and the other end of the elastic spring is fixedly connected to the inner wall of the mounting shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the motor starts, the starting of the motor drives the gear to rotate. The rotation of the gear drives the rotating plate to rotate through the gear ring. The rotation of the rotating plate causes the opening and closing plate to slide on the inner wall of the sliding groove. The inner wall of the connecting plate is provided with a sliding groove. A sliding column is fixedly connected to the outer wall of the opening and closing plate. The sliding column slides inside the sliding groove, thereby limiting the sliding trajectory of the opening and closing plate. Thus, the degree of opening and closing is controlled by limiting the degree of sliding of the opening and closing plate by the degree of rotation of the rotating plate. This adjusts the size of the opening to control the degree of ventilation, and switches between the required ventilation effect or whether ventilation is enabled, so that the ventilation effect is not too large or too small, avoiding the impact on the livestock inside the pasture.

[0024] 2. In this utility model, pressing the gear causes the wedge block to move downwards. The downward movement of the wedge block causes the limiting ball, which is stuck in the limiting hole on the inner wall of the mounting shell, to move outwards, so that the limiting ball is no longer stuck in the mounting shell. This completes the disassembly of the dust filter, allowing the filter to be removed for cleaning and replacement after long-term use, enabling the filter to filter dust brought by the fan for a long time.

[0034] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an automatic ventilation switching device for a ranch ventilator, comprising a fixed plate 1. The inner wall of the fixed plate 1 is equipped with a detachable component for removing the filter screen. This design allows the filter screen to be easily removed when cleaning or replacement is needed, ensuring the ventilation effect and air quality of the ventilator. A fixed ring 2 is fixedly connected to the inner wall of the fixed plate 1. The fixed ring 2 plays a role in fixing the internal structure and stabilizing the position of other internal components. Multiple connecting plates 3 are fixedly connected to the inner wall of the fixed ring 2. The multiple connecting plates 3 serve to connect the fixed ring 2 and the connecting ring 5, making the overall structure more stable.

[0035] Each of the multiple connecting plates 3 has a connecting ring 5 fixedly connected to its other end. The connecting ring 5 further fixes the connecting plates 3, enhancing the stability of the overall structure. Each of the multiple connecting plates 3 has a sliding column 6 slidably connected to its inner wall. The sliding column 6 slides on the inner wall of the connecting plate 3, providing a basis for the sliding of the opening and closing plate 10. Each of the multiple sliding columns 6 has an opening and closing plate 10 fixedly connected to its bottom end. The sliding column 6 drives the opening and closing plate 10 to move. The opening and closing degree of the vent is controlled by the movement of the opening and closing plate 10. Each of the multiple opening and closing plates 10 has a rotating plate 8 rotatably connected to its bottom end. The rotation of the rotating plate 8 can drive the opening and closing plate 10 to move, thereby realizing the control of the opening and closing of the vent.

[0036] A motor 18 is fixedly connected to the inner wall of the fixed plate 1. The motor 18 provides power for the operation of the entire device. A gear 7 is fixedly connected to the drive end of the motor 18. After the motor 18 starts, it drives the gear 7 to rotate, transmitting the power of the motor 18 to the gear 7. Multiple sliding grooves 9 are provided on the inner wall of the rotating plate 8. The bottoms of multiple opening and closing plates 10 are slidably connected to the inner walls of the multiple sliding grooves 9. The sliding grooves 9 provide a track for the sliding of the opening and closing plates 10, making the sliding of the opening and closing plates 10 more stable and controllable. A toothed ring 21 is fixedly connected to the outer wall of the sliding groove 9. The toothed ring 21 meshes with the gear 7, which can transmit the rotation of the gear 7 to the sliding groove 9, thereby driving the rotating plate 8 to rotate.

[0037] The outer wall of the sliding groove 9 is rotatably connected to the inner wall of the fixed ring 2, so that the sliding groove 9 can rotate stably within the fixed ring 2, ensuring the normal operation of the device. The inner walls of multiple connecting plates 3 are provided with sliding grooves 4, which provide a defined trajectory for the sliding column 6. The outer walls of multiple sliding columns 6 are slidably connected to the inner walls of multiple sliding grooves 4. The sliding trajectory of the opening and closing plate 10 is limited by the sliding of the sliding column 6 within the sliding groove 4, thereby controlling the movement of the opening and closing plate 10. The outer wall of the gear 7 is meshed with the outer wall of the gear ring 21, so that the rotation of the gear 7 can be transmitted to the gear ring 21, thereby driving the movement of the rotating plate 8 and the opening and closing plate 10. The inner wall of the fixed plate 1 is equipped with a ventilation fan 19, which can exhaust the air in the pasture and keep the air flowing smoothly.

[0038] Reference Figure 2 , Figure 5 and Figure 6 The detachable components include a mounting shell 16, which provides mounting space for internal components such as a pressing rod 17 and a wedge block 12. The pressing rod 17 is slidably connected to the inner wall of the mounting shell 16. The pressing rod 17 can slide on the inner wall of the mounting shell 16. The movement of the pressing rod 17 drives the movement of the wedge block 12. One end of the pressing rod 17 is fixedly connected to the wedge block 12. The movement of the pressing rod 17 will drive the wedge block 12 to move together, thereby controlling the limiting ball 13. Multiple return springs 14 are fixedly connected to the inner wall of the fixing plate 1. The other end of each of the multiple return springs 14 is fixedly connected to the limiting ball 13. The return springs 14 can hold the limiting ball 13 in a certain position when the limiting ball 13 is not subjected to external force, thereby playing a reset role.

[0039] An elastic spring 15 is sleeved on the outer wall of the pressing rod 17. The elastic spring 15 plays a control role on the wedge block 12, so that the wedge block 12 can be in a stable position on the inner wall of the mounting shell 16. The outer wall of the mounting shell 16 has multiple limiting holes 11. The outer walls of multiple limiting balls 13 are slidably connected to the inner walls of the multiple limiting holes 11. The limiting balls 13 can be inserted into the limiting holes 11 to fix the mounting shell 16, thereby fixing the dust filter 20. One end of the elastic spring 15 is fixedly connected to the outer wall of the wedge block 12, and the other end of the elastic spring 15 is fixedly connected to the inner wall of the mounting shell 16. The elastic spring 15 provides elastic force to the wedge block 12, so that it can stably control the limiting balls 13.

[0040] A dust filter 20 is slidably connected to the outer wall of the mounting housing 16. The dust filter 20 can slide on the outer wall of the mounting housing 16 for easy installation and removal. The outer wall of the dust filter 20 is detachably connected to the inner wall of the fixing plate 1. This arrangement allows the dust filter 20 to be easily installed on the fixing plate 1, and it is also easy to remove it for cleaning or replacement.

[0041] Working principle: When a ventilator is needed to keep the air in the pasture flowing smoothly, the ventilation can be changed by switching between different sizes of openings according to the real-time situation. The motor 18 starts, which drives the gear 7 to rotate. The rotation of the gear 7 drives the rotating plate 8 to rotate through the gear ring 21. The rotation of the rotating plate 8 causes the opening and closing plate 10 to slide on the inner wall of the sliding groove 9. At this time, the fixing ring 2 plays a role in fixing the internal structure. The fixing ring 2 and the connecting ring 5 play a role in fixing and connecting the connecting plate 3. The inner wall of the connecting plate 3 has a sliding groove 4. The outer wall of the opening and closing plate 10 is fixedly connected to the sliding column 6. The sliding column 6 slides inside the sliding groove 4, thereby limiting the sliding trajectory of the opening and closing plate 10. Thus, the degree of opening and closing is controlled by limiting the degree of sliding of the opening and closing plate 10 by the degree of rotation of the rotating plate 8.

[0042] When it is necessary to disassemble the dust filter 20, press the gear 7. The movement of the gear 7 will cause the wedge block 12 to move downward. The downward movement of the wedge block 12 will cause the limiting ball 13, which is stuck in the limiting hole 11 on the inner wall of the mounting shell 16, to move outward, so that the limiting ball 13 is no longer stuck in the mounting shell 16. At this time, the dust filter 20 can be disassembled. When it is necessary to install, install the mounting shell 16 into the inner wall of the fixing plate 1. Then the limiting ball 13 will be stuck into the inner wall of the limiting hole 11 to install the dust filter 20. The elastic spring 15 plays a control role on the wedge block 12, so that the wedge block 12 can be in a stable position on the inner wall of the mounting shell 16.

[0043] 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.
