Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding equipment, and particularly to a ventilation and heat preservation device for poultry breeding. Background Art

[0002] Poultry breeding refers to the way of artificially raising various poultry, such as chickens, ducks, geese, etc., to obtain products such as meat and eggs. Poultry breeding is generally divided into two types: egg poultry breeding and meat poultry breeding. Egg poultry breeding mainly focuses on chickens and ducks. The ventilation and heat preservation wall for poultry breeding is a wall structure specially designed for poultry breeding houses. It combines the two functions of ventilation and heat preservation, aiming to provide a comfortable and healthy growth environment for poultry. The wall is usually designed with ventilation fans to introduce fresh air or discharge the dirty air in the breeding house when needed. This helps to reduce the concentration of harmful gases in the breeding house, improve the air quality, thereby reducing the occurrence of poultry diseases. And the wall is built with materials having excellent heat preservation performance, such as sandwich panels with polystyrene boards or rock wool between double-layer steel plates. These materials can effectively prevent the transfer of heat and reduce the heat loss in the breeding house, so as to maintain the stability of the indoor temperature in winter.

[0003] However, during the use process, ventilation is generally directly carried out through the fans on the windows, which can often only achieve one-way or local air flow, and it is difficult to effectively promote the overall air flow in the breeding area, thus reducing the ventilation effect. And the ventilation method through the fans directly is relatively single, and it is very difficult to avoid ventilation dead corners. These dead corner areas may accumulate harmful gases, moisture or heat due to poor air circulation, posing a potential threat to the growth and health of animals. And fans are installed at the windows, but such a setting will affect the heat preservation efficiency in winter. Cold air will enter the breeding house through the windows, while the warm air inside the house will flow out. This air exchange will take away the heat in the breeding house, resulting in a decrease in the indoor temperature and affecting the heat preservation effect. Therefore, a ventilation and heat preservation device for poultry breeding is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art that it is difficult to effectively promote the overall air flow in the breeding area, thereby reducing the ventilation effect, the ventilation method is usually relatively single, it is very difficult to avoid ventilation dead corners, installing fans at the windows will affect the heat preservation efficiency in winter, and the air exchange in winter will take away the heat in the breeding house, resulting in a decrease in the indoor temperature and affecting the heat preservation effect, and to propose a ventilation and heat preservation device for poultry breeding.

[0015] The present invention has the following beneficial effects: 0. In the present invention, by setting the ventilation assembly, ventilation can be carried out in the breeding area by blowing in different directions through the circular groove, the first ventilation pipe and the second ventilation pipe respectively.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1 As Figure 1 - Figure 11 As shown, a ventilation and heat preservation device for poultry breeding proposed by the present invention includes a heat preservation wall body 1. A plurality of windows 2 are opened on the inner side of the heat preservation wall body 1. A first rotating rod 3 is rotatably connected to the inner side of the heat preservation wall body 1. A plurality of sealing plates 4 are installed on the outer side of the first rotating rod 3. A fan blade 11 is rotatably connected to the inner side of the window 2. A plurality of ventilation boxes 12 are installed on the side surface of the heat preservation wall body 1. A plurality of circular grooves 13 are opened on the outer side of the ventilation box 12. A ventilation component is jointly arranged on the ventilation box 12 and the heat preservation wall body 1. The ventilation component includes a second ventilation pipe 32 installed on the side surface of the ventilation box 12, a first ventilation pipe 16 movably connected to the side surface of the ventilation box 12, and a threaded rod 17 rotatably connected to the side surface of the heat preservation wall body 1. The threaded rod 17 is threadedly connected to the first ventilation pipe 16. When the fan blade 11 rotates for ventilation, the circular grooves 13, the first ventilation pipe 16, and the second ventilation pipe 32 blow air in different directions respectively. The threaded rod 17 rotates back and forth to drive the first ventilation pipe 16 to move back and forth for ventilation; An adjustment component is jointly arranged between the heat preservation wall body 1 and the ventilation box 12. The adjustment component includes a third rotating rod 25 and a second rotating rod 24 rotatably connected to the side surface of the heat preservation wall body 1, a fourth rotating rod 29 rotatably connected to the inner side of the ventilation box 12, and a plurality of baffle plates 31 installed on the outer side of the fourth rotating rod 29. When the first rotating rod 3 drives the sealing plate 4 to rotate to open the window 2, the first rotating rod 3 drives the fourth rotating rod 29 to rotate through the second rotating rod 24 and the third rotating rod 25. The rotation of the fourth rotating rod 29 causes the baffle plates 31 to adjust the area of the circular grooves 13 blocked, reduce the opening of the circular grooves, reduce air exchange, and can also completely block the circular grooves when the outside temperature is too low, playing a dual role of heat insulation and preservation and improving the heat preservation effect.

[0021] A first ring 14 is installed on the side surface of the ventilation box 12. A second ring 15 is slidably arranged on the inner side of the first ring 14. One end of the second ring 15 away from the ventilation box 12 is fixedly connected to the first ventilation pipe 16. The second ring slides in the first ring to adapt to the back-and-forth movement of the first ventilation pipe.

[0022] An active block 19 is installed on the outer side of the first ventilation pipe 16. The active block 19 is threadedly connected to the threaded rod 17. A third servo motor 20 is installed on the side of the heat-insulating wall 1. The output end of the third servo motor 20 is installed with a second worm 21. A second worm gear 18 is installed on the outer side of the threaded rod 17. The second worm gear 18 is meshed with the second worm 21. When the second worm drives the threaded rod to rotate, the acting force generated drives the active block and the first ventilation pipe to move back and forth.

[0023] An opening groove 8 is formed inside the window 2. A first support plate 9 is installed inside the opening groove 8. A second servo motor 10 is installed on the side of the first support plate 9. The output end of the second servo motor 10 is fixedly connected to the fan blade 11. By driving the fan blade to rotate with the second servo motor, wind force can be generated when the fan blade rotates.

[0024] Both the first ring 14 and the second ventilation pipe 32 communicate with the circular groove 13. The second ring 15 communicates with the first ventilation pipe 16. The wind force enters the second ventilation pipe and the first ventilation pipe through the circular groove.

[0025] A plurality of second support plates 23 are installed on the side of the heat-insulating wall 1. Both the second rotating rod 24 and the third rotating rod 25 are rotatably connected to the side of the second support plate 23. A transmission belt 22 is jointly sleeved between the first rotating rod 3 and the second rotating rod 24. A first gear 26 is installed on the outer side of the second rotating rod 24. A second gear 27 is installed on the outer side of the third rotating rod 25. The first gear 26 is meshed with the second gear 27. A second bevel gear 30 is installed at the end of the fourth rotating rod 29. A first bevel gear 28 is installed at the end of the third rotating rod 25. The first bevel gear 28 is meshed with the second bevel gear 30. A support frame 33 is installed at the end of the fourth rotating rod 29. The support frame 33 is fixedly connected to the baffle 31.

[0026] A square rod 34 is installed on the outer side of the second ring 15. A sliding groove 35 is formed inside the first ring 14. The second rotating rod 24 is slidably arranged inside the sliding groove 35 to ensure the linear movement of the second ring.

[0027] The size of the opening of the first ring 14 is adapted to the size of the second ring 15. The size of the opening of the sliding groove 35 is adapted to the size of the square rod 34 to enable the stable movement of the second ring.

[0028] In this embodiment, when ventilation is required during poultry farming, the first servo motor 6 can be started at this time. The first servo motor 6 drives the first worm 7 to rotate. Since the first worm 7 meshes with the first worm gear 5, when the first worm 7 rotates, it can drive the first rotating rod 3 to rotate through the first worm gear 5. When the first rotating rod 3 rotates, it can drive the sealing plate 4 to rotate until the sealing plate 4 is rotated to 90 degrees. Then, the second servo motor 10 can be started to drive the fan blade 11 to rotate through the second servo motor 10. When the fan blade 11 rotates, wind can be generated, and then it is blown into the breeding area in different directions through the circular groove 13, the first ventilation pipe 16 and the second ventilation pipe 32 respectively for ventilation. By blowing from multiple different directions, the air flow in the breeding area can be promoted more effectively, thereby accelerating air exchange. At the same time, the third servo motor 20 can be started, and the third servo motor 20 can be made to drive the second worm 21 to rotate back and forth. Since the second worm 21 meshes with the second worm gear 18, when the second worm 21 rotates back and forth, it can drive the threaded rod 17 to rotate back and forth through the second worm gear 18. When the threaded rod 17 rotates back and forth, it can drive the movable block 19 and the first ventilation pipe 16 to move back and forth through the acting force generated during rotation. When the first ventilation pipe 16 moves back and forth, it slides inside the first ring 14 and the sliding groove 35 through the second ring 15 and the square rod 34 respectively to adapt to the back-and-forth movement of the first ventilation pipe 16. By blowing into the breeding area through the back-and-forth movement of the first ventilation pipe 16, it can ensure that all corners of the breeding area can be fully ventilated.

[0029] Embodiment 2 As Figure 1 - Figure 11 shown, based on Embodiment 1, the first servo motor 6 is installed on the side of the heat preservation wall 1, and the output end of the first servo motor 6 extending to the inside of the heat preservation wall 1 is installed with the first worm 7. The first worm gear 5 is installed on the outer side of the first rotating rod 3. The first worm gear 5 meshes with the first worm 7. After the first servo motor is started, the first rotating rod is driven to rotate through the first worm and the first worm gear.

[0030] The number of multiple circular grooves 13 is multiple groups and is evenly distributed in a circle. The number of multiple baffles 31 is multiple groups and is evenly distributed in a circle. The size of the baffle 31 is adapted to the opening size of the circular groove 13 to ensure the integrity of the occlusion of the circular groove.

[0031] In this embodiment, when the first rotating rod 3 rotates to drive the sealing plate 4 to rotate, the second rotating rod 24 can be driven to rotate through the transmission belt 22 at this time. When the second rotating rod 24 rotates, the third rotating rod 25 can be driven to rotate through the first gear 26 and the second gear 27. When the third rotating rod 25 rotates, the first bevel gear 28 can be driven to rotate. Since the first bevel gear 28 meshes with the second bevel gear 30, when the first bevel gear 28 rotates, the fourth rotating rod 29 can be driven to rotate through the second bevel gear 30. When the fourth rotating rod 29 rotates, the baffle 31 can be driven to rotate through the support frame 33, so that the baffle 31 no longer blocks the circular groove 13, and the wind is transmitted through the circular groove 13. When heat preservation is required without ventilation, the first rotating rod 3 can be rotated in reverse at this time to drive the sealing plate 4 to block the window 2, and at the same time, the second rotating rod 24 and the third rotating rod 25 are driven to rotate in reverse through the transmission belt 22, so that the fourth rotating rod 29 is driven to rotate in reverse through the first bevel gear 28 and the second bevel gear 30. After the fourth rotating rod 29 rotates in reverse, the baffle 31 can be driven to block the circular groove 13 through the support frame 33. The opening of the circular groove 13 can also be adjusted by adjusting and reducing the area of the circular groove 13 blocked by the baffle 31 to reduce air exchange. And when the outside temperature is too low, the circular groove 13 can also be completely blocked to play a dual heat insulation and preservation role and improve the heat preservation effect.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
