Description

Technical Field

[0001] This utility model belongs to the field of meat duck farming technology, and in particular relates to the ventilation system for meat duck farms. Background Technology

[0002] During duck farming, ducks exhale carbon dioxide and excrete feces, both of which lead to a decline in air quality inside the duck house. If ventilation is not timely, the carbon dioxide concentration inside the duck house will increase, and the fermentation and decay of feces will produce harmful gases such as ammonia and hydrogen sulfide, while also increasing humidity inside the house. This not only affects the growth and development of the ducks but may also cause respiratory diseases and other health problems.

[0003] Ventilation in duck farms can be achieved through both natural and mechanical ventilation. Natural ventilation relies heavily on the design of the duck house, such as ventilation openings in doors, windows, and walls. Mechanical ventilation, on the other hand, requires the use of equipment such as fans. Some ventilation fans are equipped with sterilization filter plates to sterilize the incoming air. Since these sterilization plates are consumables and need to be replaced frequently, and the connection between the sterilization plates and the ventilation fans is secured with multiple bolts, requiring the bolts to be turned before and after disassembly, a ventilation system for duck farms is needed. This system can pre-fix the sterilization plates by inserting them into the ventilation fans, and then use a flipping pressure plate to press the sterilization plates firmly, thereby improving the ease of replacement and disassembly of the sterilization plates. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation system for duck farming houses. By first inserting the sterilization plate and the ventilation fan for pre-fixation, and then pressing the sterilization plate by flipping the pressure plate, the convenience of replacing and disassembling the sterilization plate is improved, thereby solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a ventilation system for duck breeding houses, comprising a ventilation fan, a sterilization filter plate on the surface of the ventilation fan, a horizontal plate fixedly connected to the surface of the sterilization filter plate, a U-shaped frame fixedly connected to the top of the ventilation fan by bolts, a threaded rod rotatably connected to the inner wall of the U-shaped frame and having a sliding groove, a threaded sleeve block threadedly connected to the surface of the threaded rod, two symmetrically arranged limiting slide rods fixedly connected to the surface of the threaded sleeve block, a pressure block rotatably connected to the inner wall of the U-shaped frame, a connecting rod rotatably connected between the pressure block and the limiting slide rod, a pad fixedly connected to the inner wall of the U-shaped frame by bolts, and a pressure groove on the top of the horizontal plate.

[0006] Preferably, the surface of the ventilation fan has an insertion hole, and the surface of the sterilization filter plate is integrally formed with an insertion rod, which is inserted into the inner cavity of the insertion hole.

[0007] Preferably, the limiting slide rod is slidably connected to the inner wall of the slide groove.

[0008] Preferably, a handle is fixedly connected to the top end of the threaded rod.

[0009] Preferably, the inner wall of the U-shaped frame is fixedly connected with a reinforcing rod.

[0010] Preferably, a pad is attached to the surface of the pressing block.

[0011] The beneficial effects of this utility model are:

[0012] This utility model uses a socket and a rod to be inserted, and then the threaded sleeve block drives the limiting slide rod to move, so that the limiting slide rod drives the pressure block to flip through the connecting rod. Then the pressure block presses the horizontal plate onto the top of the pad, thus achieving the purpose of improving the convenience of sterilization plate replacement and disassembly by first inserting the sterilization plate and the ventilation fan for pre-fixation, and then pressing the sterilization plate by flipping the pressure plate.

[0013] 2. By setting up the handle block, this utility model increases the contact area at the top of the threaded rod, avoiding slippage when directly holding and rotating the threaded rod, and improving the reliability of holding and rotating the threaded rod.

[0014] 3. This utility model strengthens the inner wall of the U-shaped frame by adding reinforcing rods, thereby improving the stability of the U-shaped frame structure and thus increasing the structural strength of the U-shaped frame;

[0015] 4. By setting up pads, this utility model protects the inner wall of the pressure block, preventing damage to the surface of the horizontal plate when the pressure block directly squeezes it, thereby improving the service life of the horizontal plate. Attached Figure Description

[0021] In the following description, embodiments of the ventilation system for duck farming sheds of this invention will be described with reference to the accompanying drawings. Example 1

[0022] Figure 1-4 This invention illustrates a ventilation system for a duck farm, comprising a ventilation fan 1. The surface of the ventilation fan 1 is provided with a sterilization filter plate 2. An insertion hole 3 is formed on the surface of the ventilation fan 1. An insertion rod 4 is integrally formed on the surface of the sterilization filter plate 2, and the insertion rod 4 is inserted into the inner cavity of the insertion hole 3. A horizontal plate 5 is fixedly connected to the surface of the sterilization filter plate 2. A U-shaped frame 6 is fixedly connected to the top of the ventilation fan 1 by bolts. A threaded rod 7 is rotatably connected to the inner wall of the U-shaped frame 6 and has a sliding groove 10. A threaded sleeve block 8 is threadedly connected to the surface of the threaded rod 7. Two symmetrically arranged limiting slide rods 9 are fixedly connected to the surface of the threaded sleeve block 8. The limiting slide rods 9 are slidably connected to the inner wall of the sliding groove 10. A handle 11 is fixedly connected to the top of the threaded rod 7. The handle 11 increases the contact area of ​​the top of the threaded rod 7, preventing slippage when the threaded rod 7 is rotated by hand, and improving the reliability of the threaded rod 7 when rotating. A pressure block 12 is rotatably connected to the inner wall of the U-shaped frame 6. A connecting rod 13 is rotatably connected to the pressure block 12 and the limiting slide rod 9. A pad 16 is fixedly connected to the inner wall of the U-shaped frame 6 by bolts. A pressure groove 17 is opened on the top of the horizontal plate 5. The pressure groove 17 limits the compaction and fit between the pressure block 12 and the horizontal plate 5, preventing relative lateral slippage between the pressure block 12 and the horizontal plate 5, thereby improving the stability of the pressure block 12 when pressing the horizontal plate 5. Example 2

[0023] Figure 1-4This invention illustrates a ventilation system for a duck farm according to an embodiment of the present invention. The system includes a ventilation fan 1. A sterilization filter plate 2 is mounted on the surface of the ventilation fan 1. A horizontal plate 5 is fixedly connected to the surface of the sterilization filter plate 2. A U-shaped frame 6 is bolted to the top of the ventilation fan 1. A threaded rod 7 is rotatably connected to the inner wall of the U-shaped frame 6 and has a sliding groove 10. A threaded sleeve block 8 is threadedly connected to the surface of the threaded rod 7. Two symmetrically arranged limiting slide rods 9 are fixedly connected to the surface of the threaded sleeve block 8. A pressure block 12 is rotatably connected to the inner wall of the U-shaped frame 6. The pressure block 12 and the limiting slide rods 9 rotate together. The U-shaped frame 6 is connected by a connecting rod 13, and the inner wall of the U-shaped frame 6 is fixedly connected by a reinforcing rod 14. The reinforcing rod 14 reinforces the inner wall of the U-shaped frame 6, improving the stability of the U-shaped frame 6 structure and thus increasing the structural strength of the U-shaped frame 6. A pad 15 is pasted on the surface of the pressure block 12. The pad 15 protects the inner wall of the pressure block 12, preventing damage to the surface of the horizontal plate 5 when the pressure block 12 directly presses against it, thereby improving the service life of the horizontal plate 5. A pad 16 is fixedly connected to the inner wall of the U-shaped frame 6 by bolts, and a pressure groove 17 is opened on the top of the horizontal plate 5.

[0024] Working principle: When using this utility model, the user holds the sterilization filter plate 2 and places it against the ventilation fan 1, so that the insertion hole 3 and the insertion rod 4 are inserted. At this time, the horizontal plate 5 reaches the top of the pad 16. Then, the threaded rod 7 is rotated to drive the threaded sleeve block 8 to move. The threaded sleeve block 8 drives the limiting slide rod 9 to move, so that the limiting slide rod 9 drives the pressure block 12 to flip through the connecting rod 13. During this process, the movement of the limiting slide rod 9 is limited by the setting of the sliding groove 10, which prevents the limiting slide rod 9 from shaking during the movement. Then, the pressure block 12 presses the horizontal plate 5 to the top of the pad 16, so that the ventilation fan 1 and the sterilization filter plate 2 are firmly connected. Moreover, in this process, only a single threaded rod 7 needs to be rotated, without disassembling and assembling multiple bolts. This realizes the pre-fixation by first inserting the sterilization plate and the ventilation fan, and then pressing the sterilization plate by flipping the pressure plate, thereby improving the convenience of replacing and disassembling the sterilization plate.

[0025] In summary, the ventilation system of this duck farm uses the insertion hole 3 to connect with the insertion rod 4. Then, the threaded sleeve block 8 drives the limiting slide rod 9 to move, so that the limiting slide rod 9 drives the pressure block 12 to flip through the connecting rod 13. Subsequently, the pressure block 12 presses the horizontal plate 5 onto the top of the pad 16. This achieves the purpose of improving the convenience of replacing and disassembling the sterilization plate by first pre-fixing it by connecting it with the ventilation fan, and then pressing the sterilization plate by flipping the pressure plate.
