Description

Technical Field

[0001] This utility model relates to the field of ventilation devices, specifically to a ventilation system for sheep sheds. Background Technology

[0002] The existing sheepfold structure is relatively simple, and ventilation is basically achieved by installing windows on the walls for cross-ventilation. Such sheepfolds have poor ventilation, which can easily lead to the growth of bacteria inside the sheepfold and is not conducive to the growth of sheep.

[0003] Existing technology center, utility model patent application number CN202021367679.5 discloses a novel ventilation device for sheep farming, including a ventilation pipe, a sleeve connected to the outer side of one end of the ventilation pipe, a fixing plate welded to one end of the sleeve, a fan installed at one end of the ventilation pipe, a liquid storage tank welded to the upper end of the ventilation pipe, a liquid extraction pipe installed on one side of the liquid storage tank, a first water pipe installed at the lower end of a water pump, a second water pipe welded to the upper end of the first water pipe away from the water pump and located inside the ventilation pipe, and an atomizing nozzle threaded to the lower end of the second water pipe. This device places the sleeve inside a pre-drilled hole in the wall. After the fan is started, it blows a large amount of fresh air into the ventilation pipe. Disinfectant is sprayed into the ventilation pipe through the atomizing nozzle, and then blown into the sheep pen by the fan to disinfect the interior of the sheep pen.

[0004] However, when the disinfectant in the aforementioned ventilation system is blown into the sheep pen by the fan, the fixed position of the ventilation pipes can easily lead to uneven distribution of the disinfectant inside the sheep pen, which reduces the disinfection effect and needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a ventilation system for sheep sheds that provides good ventilation and allows for more even distribution of disinfectant inside the shed, thereby addressing the deficiencies mentioned in the background art.

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

[0007] A ventilation system for sheep sheds includes a horizontally extending ventilation duct, one end of which is connected to a fan via a pipe; a plurality of air outlet ducts evenly spaced along the length of the ventilation duct are fixedly installed at the bottom of the ventilation duct, the upper end of the air outlet duct is connected to the ventilation duct, and a plurality of air guide plates that can swing back and forth are provided in the lower end of the air outlet duct, the plurality of air guide plates being arranged in parallel; an installation plate is fixedly installed in the air outlet duct above the plurality of air guide plates, and a vertically extending disinfection tube is rotatably installed on the installation plate, the upper end of the disinfection tube being connected to a liquid supply mechanism, and the lower end of the disinfection tube having an inclined tube, the end of the inclined tube away from the disinfection tube having an atomizing nozzle inclined towards the lower side of the disinfection tube; a power mechanism for driving the disinfection tube to rotate is provided on one side of the air outlet duct.

[0008] As a further improvement, a rotary joint is fixedly installed at the bottom of the mounting plate, and the upper end of the disinfection tube is rotatably installed at the lower end of the rotary joint. A liquid inlet is provided on one side of the rotary joint, and the liquid inlet is connected to the liquid supply mechanism.

[0009] As a further improvement, the power mechanism includes a motor installed on the outside of the air outlet duct, and the output end of the motor is provided with a vertically extending shaft, which is connected to the disinfection duct by a belt.

[0010] As a further improvement, a horizontally extending rotating shaft is fixedly installed at the middle of the left and right ends of the air guide plate, and the rotating shaft is rotatably installed on the side wall of the air outlet pipe; a lever is fixedly installed above the air guide plate and arranged parallel to the rotating shaft; a movable plate is slidably installed in the air outlet pipe, and the movable plate is provided with slots corresponding to the levers one by one. The slots are vertically extending strips, and the levers are movably installed in the corresponding slots. When the movable plate moves back and forth, the air guide plate swings back and forth through the levers.

[0011] As a further improvement, a connecting plate is fixedly installed on the movable plate, a vertically extending first pin is fixedly installed on the connecting plate, a turntable is coaxially fixedly installed on the rotating shaft, a vertically extending second pin is fixedly installed on the turntable, and a connecting rod is hinged between the first pin and the second pin. When the turntable rotates, it drives the connecting plate and the movable plate to move back and forth through the connecting rod.

[0012] As a further improvement, an opening is provided on one side of the air outlet duct, through which the belt and the connecting rod pass; a shield covering the opening is fixedly installed on the outside of the air outlet duct, the motor is installed on the outside of the shield, and the rotating shaft extends into the shield.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The bottom of the ventilation duct is fixedly equipped with multiple air outlet pipes that are evenly spaced along its length. Fresh air from outside is evenly dispersed into the sheepfold through the multiple air outlet pipes, resulting in better ventilation.

[0015] When the motor is working, it drives the disinfection tube to rotate, which in turn drives the atomizing nozzle to rotate, thereby continuously changing the spraying direction of the atomizing nozzle, so that the liquid medicine sprayed by the atomizing nozzle is evenly dispersed into the air outlet pipe, and the liquid medicine spray is more evenly distributed in the ventilation pipe.

[0016] The motor drives the disinfection tube to rotate, while simultaneously causing multiple air guide plates to swing back and forth, thereby continuously changing the air outlet direction at the lower end of the air outlet tube. This allows the disinfectant spray to be evenly dispersed into the sheepfold as the air guide plates swing back and forth, resulting in better disinfection of the sheepfold.

[0023] 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.

[0024] like Figures 1 to 4 As shown, a ventilation system for sheep sheds includes a horizontally extending ventilation pipe 1, which is fixedly installed on the ceiling inside the sheep shed. The left end of the ventilation pipe 1 is closed, and the right end of the ventilation pipe 1 is connected to a fan 3 via a pipe 2. The fan 3 is located outside the sheep shed. Multiple air outlet pipes 4, evenly spaced along the length of the ventilation pipe 1, are welded to the bottom of the ventilation pipe 1. The upper ends of the air outlet pipes 4 are connected to the ventilation pipe 1. When the fan 3 is working, it draws fresh air from outside into the sheep shed through the pipe 2, the ventilation pipe 1, and the multiple air outlet pipes 4, resulting in better ventilation.

[0025] like Figure 3 As shown, the lower end of the air outlet duct 4 is provided with multiple air guide plates 5 that can swing back and forth, and the multiple air guide plates 5 are arranged in parallel; specifically, the air guide plate 5 is a long strip extending to the left and right, and the middle part of the left and right ends of the air guide plate 5 is respectively welded or fixed by bolts to a horizontally extending rotating shaft 6, and the two rotating shafts 6 are respectively rotatably installed on the left and right side walls of the air outlet duct 4.

[0026] like Figure 4 As shown, an upwardly extending bracket 7 is fixedly installed on the air guide plate 5 by bolts. A lever 30 parallel to the rotating shaft 6 is welded onto the bracket 7. A movable plate 8 is slidably installed inside the air outlet pipe 4. The movable plate 8 extends forward and backward, and mounting parts 9 with ninety-degree bends are respectively provided at the front and rear ends of the movable plate 8. Guide rods 10 extending forward and backward are threadedly connected to the inner sides of the front and rear side walls of the air outlet pipe 4, and the mounting parts 9 are slidably installed on the corresponding guide rods 10, thereby providing guidance for the forward and backward movement of the movable plate 8. The bottom of the movable plate 8 is provided with slots 11 corresponding to the levers 30. The slots 11 are long and vertically extending. The levers 30 are movably installed in the corresponding slots 11. The width of the slots 11 is the same as the diameter of the levers 30 or the width of the slots 11 is slightly larger than the diameter of the levers 30. When the movable plate 8 moves back and forth, it drives the air guide plate 5 to swing back and forth through the levers 30. The back and forth swing of the air guide plate 5 continuously changes the air outlet direction at the lower end of the air outlet pipe 4, so that the fresh air outside is evenly distributed into the sheepfold.

[0027] like Figure 3As shown, an installation plate 12 is fixedly installed inside the air outlet duct 4 located above multiple air guide plates 5. One end of the installation plate 12 is welded to the inner wall of the air outlet duct 4. A rotary joint 13 is provided below the installation plate 12. The upper end of the rotary joint 13 is fixedly installed on the bottom of the installation plate 12 by bolts. A liquid inlet 14 is provided on one side of the rotary joint 13, and the liquid inlet 14 is connected to the liquid supply mechanism; Figure 1 As shown, the liquid supply mechanism specifically includes a liquid storage tank 15, a main liquid supply pipe 16 connected to the liquid storage tank 15, a pressure pump on the main liquid supply pipe 16, and a liquid supply branch pipe 17 corresponding to the air outlet pipe 4 on the main liquid supply pipe 16. The end of the liquid supply branch pipe 17 away from the main liquid supply pipe 16 passes through the side wall of the air outlet pipe 4 and enters the interior of the air outlet pipe 4 and is connected to the liquid inlet 14. The lower end of the rotary joint 13 is the liquid outlet end. A downwardly extending disinfection pipe 18 is rotatably installed at the lower end of the rotary joint 13. The disinfection pipe 18 is located at the center of the air outlet pipe 4. The lower end of the disinfection pipe 18 is integrally formed with an inclined pipe 19 that is inclined downward. An atomizing nozzle 20 that is inclined towards the lower side of the disinfection pipe 18 is installed at the end of the inclined pipe 19 away from the disinfection pipe 18.

[0028] A power mechanism for rotating the disinfection tube 18 is provided on one side of the air outlet duct 4. Specifically, such as... Figure 2 and Figure 3 As shown, the power mechanism includes a motor 31 located outside the air outlet duct 4. The front side wall of the air outlet duct 4 is provided with an opening 32. A shield 21 covering the opening 32 is also fixedly installed on the front side of the air outlet duct 4 by bolts to prevent air leakage at the opening 32. The motor 31 is installed on the top of the shield 21 by bolts. The output end of the motor 31 is provided with a rotating shaft 22 extending downward into the shield 21. A drive pulley 23 is fixedly installed on the rotating shaft 22. A driven pulley 24 is fixedly installed on the disinfection tube 18. A belt 25 is connected between the drive pulley 23 and the driven pulley 24. The belt 25 passes through the opening 32.

[0029] When the motor 31 is working, it drives the drive pulley 23 to rotate through the shaft 22. The drive pulley 23 drives the disinfection tube 18 to rotate through the belt 25. In turn, the disinfection tube 18 drives the atomizing nozzle 20 to rotate, thereby continuously changing the spraying direction of the atomizing nozzle 20. This makes the liquid medicine sprayed by the atomizing nozzle 20 evenly dispersed into the air outlet duct 4, and then the liquid medicine sprayed is evenly dispersed into the sheepfold as the air guide plate 5 swings back and forth.

[0030] like Figure 3As shown, an inverted L-shaped connecting plate 26 is fixedly installed on the movable plate 8. The vertical part of the connecting plate 26 is fixedly connected to the movable plate 8 by bolts. The horizontal part of the connecting plate 26 extends to the rear side of the opening 32. A vertically extending first pin 27 is fixedly installed at the bottom of the horizontal part of the connecting plate 26. A circular turntable 28 is coaxially fixedly installed at the lower end of the rotating shaft 22. A vertically extending second pin 33 is eccentrically fixedly installed at the bottom of the turntable 28. A connecting rod 29 is hinged between the first pin 27 and the second pin 33. The connecting rod 29 passes through the opening 32. When the turntable 28 rotates, it drives the connecting plate 26 and the movable plate 8 to move back and forth through the connecting rod 29. In turn, the multiple air guide plates 5 driven by the movable plate 8 swing back and forth.
