DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and examples.

[0029] Example 1

[0030] A ventilation system for laying duck farming, such as Figure 1 and Figure 2As shown, it includes a ventilation duct 1, a transverse duct 2, a first fixed block 3, a connecting rope 4, a fixing frame 5, a ventilation mechanism 6 and a scraping mechanism 7. The transverse duct 2 is connected to the right side of the lower part of the ventilation duct 1, and the transverse duct 2 is connected to the ventilation duct 1. There are two fixing frames 5, and the two fixing frames 5 are respectively connected to the left and right sides of the lower part of the ventilation duct 1. The fixing frames 5 are connected to the connecting rope 4, and the upper side of the connecting rope 4 is connected to the first fixed block 3. The first fixed block 3 is used to be installed on the top wall of the house. A ventilation mechanism 6 is provided on the upper part of the ventilation duct 1. The ventilation mechanism 6 can speed up the flow rate of air inside the ventilation duct 1. A scraping mechanism 7 is provided inside the transverse duct 2. The scraping mechanism 7 can scrape the duck feathers on the inner wall of the transverse duct 2.

[0031] like Figure 2 、 Figure 3 and Figure 4 As shown, the ventilation mechanism 6 includes a fixed frame 61, fan blades 62, a servo motor 63, a protective cover 64 and a worm 65. The fixed frame 61 is welded to the upper side of the interior of the ventilation duct 1, the servo motor 63 is bolted to the middle of the fixed frame 61, the fan blades 62 are connected to the upper part of the output shaft of the servo motor 63, the fan blades 62 are located inside the fixed frame 61, and the lower side of the fixed frame 61 is connected to the protective cover 64. The output shaft of the servo motor 63 passes through the protective cover 64, and the output shaft of the servo motor 63 is rotatably connected to the protective cover 64. The lower part of the output shaft of the servo motor 63 is connected to the worm 65, and the bottom of the worm 65 is rotatably connected to the bottom wall of the ventilation duct 1.

[0032] like Figure 2 and Figure 5 As shown, the scraping mechanism 7 includes a worm gear 71, a bevel gear 72, a pulley group 73 and a rotating frame 74. The rotating frame 74 is rotatably connected to the inside of the horizontal pipe 2. The rotation of the rotating frame 74 can scrape off the duck feathers adsorbed on the inner wall of the horizontal pipe 2. The lower part of the ventilation duct 1 is rotatably connected to the worm gear 71, the worm gear 71 is engaged with the worm 65, the bevel gear 72 is connected to the front side of the worm gear 71, and the left side of the rear wall of the horizontal pipe 2 is also rotatably connected to the bevel gear 72. The two bevel gears 72 are meshed with each other. A pulley group 73 is connected between the right part of the bevel gear 72 on the right and the left part of the rotating frame 74. The pulley group 73 consists of two transmission wheels and a belt. The two transmission wheels are respectively connected to the right part of the bevel gear 72 on the right and the left part of the rotating frame 74, and a belt is wound between the two transmission wheels.

[0033] During the egg duck breeding process, when the duck house needs to be ventilated, first install the first fixing block 3 on the top wall of the house, fix the first fixing block 3, and hang the ventilation duct 1 and the horizontal duct 2 on the house through the connecting rope 4 and the fixing frame 5, and the upper part of the ventilation duct 1 extends out of the top of the house, so that the inside of the duck house can be ventilated through the ventilation duct 1 and the horizontal duct 2, and then turn on the servo motor 63, so that the output shaft of the servo motor 63 rotates, and then drives the fan blades 62 to rotate. The rotation of the fan blades 62 can speed up the flow rate of air inside the ventilation duct 1, thereby making the ventilation effect better. Since there are many duck feathers floating in the air in the duck house, the duck feathers will float into the horizontal duct 2 during the ventilation of the duck house, so the duck feathers in the horizontal duct 2 need to be cleaned, and when the output shaft of the servo motor 63 rotates, The output shaft of the servo motor 63 will also drive the worm 65 to rotate, and the worm 65 rotates to drive the worm wheel 71 to rotate, and then the bevel gear 72, the pulley group 73 and the rotating frame 74 rotate. The rotation of the rotating frame 74 can scrape the duck feathers on the inner wall of the horizontal pipe 2, and the rotation of the rotating frame 74 can also transport the scraped duck feathers to the right, so that the duck feathers are transported out of the horizontal pipe 2. When the duck house does not need to be ventilated, the servo motor 63 is turned off, so that the fan blades 62 and the worm 65 stop rotating, and then the worm wheel 71, the bevel gear 72, the pulley group 73 and the rotating frame 74 stop rotating. Repeat the above operation to ventilate the duck house, and in the process of ventilation, the duck feathers on the inner wall of the horizontal pipe 2 can also be scraped and output, which is beneficial for the horizontal pipe 2 to ventilate the duck house and improve the ventilation efficiency.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1 、 Figure 6 and Figure 7 As shown, it also includes an opening and closing mechanism 8, which includes a fixed seat 81, a cover plate 82, a fixed shaft 83, a first torsion spring 84, a wire pulley 85, a pull rope 86 and a hook 87. The hook 87 is fixed to the left side of the lower part of the ventilation duct 1. There are two fixed seats 81, and the two fixed seats 81 are respectively connected to the front and rear sides of the upper part of the ventilation duct 1. The fixed seats 81 are rotatably connected to the fixed shafts 83, and the fixed shafts 83 are connected to the cover plates 82. The lower sides of the cover plates 82 are in contact with the upper side of the ventilation duct 1. The cover plates 82 are used to close the upper side of the ventilation duct 1. The left side of the fixed shaft 83 is connected to the wire pulley 85, and the first torsion spring 84 is connected between the right side of the wire pulley 85 and the left side of the fixed seat 81. The first torsion spring 84 is wound around the fixed shaft 83, and the pull rope 86 is wound between the two wire pulleys 85.

[0036] Since the upper side of the ventilation duct 1 is exposed to the outdoors, when it is cloudy and rainy, rainwater will drip into the ventilation duct 1. Therefore, in cloudy and rainy weather, the upper side of the ventilation duct 1 is closed. When people need to ventilate the duck house, they pull the pulley 86 downward and hang the lower part of the pulley 86 on the hook 87. When the pulley 86 is pulled downward, the pulley 86 drives the wire wheel 85 and the fixed shaft 83 to rotate, the first torsion spring 84 is twisted, and then the cover plate 82 is rotated, the upper side of the ventilation duct 1 is opened, and then the duck house can be ventilated. For ventilation, when it is rainy and the upper side of the ventilation duct 1 needs to be closed, the pull rope 86 is removed from the hook 87 and the pull rope 86 is loosened. Under the action of the first torsion spring 84, the wire pulley 85 and the fixed shaft 83 will rotate in the opposite direction, and then drive the cover 82 to reverse and reset, so that the cover 82 closes the upper side of the ventilation duct 1, so as to prevent rainwater from dripping into the ventilation duct 1 and prevent the electronic components inside the ventilation duct 1 from being wetted by rainwater, which may cause malfunction of the electronic components, thereby protecting the electronic components and reducing economic losses.

[0037] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, it also includes a blocking mechanism 9, which includes a connecting cover 91, a screw rod 92, a pressure plate 93, a turning handle 94 and a scraper rod 95. The connecting cover 91 is threadedly connected to the right part of the horizontal pipe 2. A plurality of circular holes are opened on the connecting cover 91. The connecting cover 91 can prevent duck feathers from floating into the horizontal pipe 2. The screw rod 92 is threadedly connected to the middle of the right part of the connecting cover 91. The pressure plate 93 is connected to the left side of the screw rod 92. The turning handle 94 is fixed to the right side of the screw rod 92. The scraper rod 95 is connected to the right part of the screw rod 92. The scraper rod 95 is fitted with the top of the connecting cover 91. The scraper rod 95 is rotated to scrape off the duck feathers on the outer wall of the connecting cover 91.

[0038] During the ventilation of the horizontal pipe 2, the connecting cover 91 can prevent the duck feathers from floating into the horizontal pipe 2 and protect the horizontal pipe 2. After a period of use, the outer wall of the connecting cover 91 will also absorb the necessary duck feathers. In order to prevent the round holes on the connecting cover 91 from being blocked, it is necessary to clean the duck feathers absorbed on the outer wall of the connecting cover 91. First, the screw rod 92 and the scraper rod 95 are driven to rotate by the turning handle 94. The rotation of the scraper rod 95 can scrape off the duck feathers absorbed on the outer wall of the connecting cover 91 to prevent the round holes on the connecting cover 91 from being blocked. At the same time, the rotation of the screw rod 92 will also drive the scraper rod 95 and the pressure plate 93 to move to the right. The rightward movement of the pressure plate 93 can The duck feathers inside the connecting cover 91 are pressed to the right so that the duck feathers are pressed between the pressure plate 93 and the right inner wall of the connecting cover 91. Then, the connecting cover 91 is removed from the right part of the horizontal pipe 2 by rotating the connecting cover 91. Then, the screw rod 92 is reversed by turning the handle 94. The reversal of the screw rod 92 drives the pressure plate 93 and the scraper rod 95 to move to the left. The pressure plate 93 moves to the left to loosen the duck feathers. The duck feathers can then be cleaned. When the connecting cover 91 is cleaned, the connecting cover 91 is reversed and turned back to the right part of the horizontal pipe 2. In summary, the duck feathers adsorbed on the outer wall of the connecting cover 91 can be scraped off by rotating the scraper rod 95 to avoid affecting the ventilation effect of the connecting cover 91.

[0039] like Figure 2 、 Figure 10 and Figure 11 As shown, it also includes a protective mechanism 10, which includes a second fixed block 101, a protective net 102, a first connecting frame 103, a rod 104 and a spring 105. Three second fixed blocks 101 are connected to the upper side of the inner wall of the ventilation duct 1 along the circumferential direction, and the protective net 102 is placed between the upper sides of the second fixed blocks 101. The protective net 102 is located above the fan blades 62, and the protective net 102 can protect the fan blades 62. The protective net 102 is slidably connected to the inner wall of the ventilation duct 1, and the number of the first connecting frames 103 is two. The two first connecting frames 103 are respectively connected to the left and right sides of the upper part of the ventilation duct 1, and the first connecting frames 103 are slidably connected with the rods 104. The inside of the rods 104 is in contact with the upper side of the protective net 102, and the rods 104 can protect the protective net 102. Springs 105 are connected between the rods 104 and the outer sides of the first connecting frames 103, and the springs 105 are all wound around the rods 104.

[0040] When the upper side of the ventilation duct 1 is opened, in order to prevent falling objects from damaging the fixing frame 61 and the fan blades 62, the protective mechanism 10 can be used to operate. When there is a falling object above the ventilation duct 1, the falling object will fall onto the protective net 102 and will not directly hit the fixing frame 61 and the fan blades 62. In this way, the fixing frame 61 and the fan blades 62 can be protected. When people need to clean the dust and impurities on the protective net 102, the rod 104 is moved to the side away from each other, so that the rod 104 is away from the protective net. On the upper side of the net 102, the spring 105 is stretched, and then the protective net 102 can be taken out upward to clean the dust and impurities on the protective net 102. When the protective net 102 is cleaned, the protective net 102 is pushed back downward so that the protective net 102 is placed on the second fixed block 101, and then the insertion rod 104 is released. Under the action of the spring 105, the insertion rod 104 moves to the side close to each other and contacts the upper side of the protective net 102, limiting the protective net 102 and improving the stability of the protective net 102.

[0041] like Figure 1 、 Figure 2 and Figure 12 As shown, it also includes a collecting mechanism 11, which includes a second connecting frame 111, a collecting frame 112 and a limiting component. The second connecting frame 111 is fixed to the right part of the horizontal pipe 2, and the collecting frame 112 is placed on the right part of the second connecting frame 111. The collecting frame 112 is located below the connecting cover 91. The collecting frame 112 can collect the duck feathers inside the connecting cover 91. A limiting component is provided on the right part of the second connecting frame 111, and the limiting component can limit the collecting frame 112.

[0042] like Figure 12 As shown, the limiting assembly includes a rotating shaft 113, a limiting block 114 and a second torsion spring 115. There are two rotating shafts 113, and the two rotating shafts 113 are rotatably connected to the front and rear sides of the right part of the second connecting frame 111. A second torsion spring 115 is connected between the rotating shaft 113 and the outer side of the second connecting frame 111. The second torsion spring 115 is wound on the rotating shaft 113. The rotating shaft 113 is connected to a limiting block 114. The limiting blocks 114 are in contact with the right side of the collection frame 112. The limiting blocks 114 can prevent the collection frame 112 from moving to the right.

[0043] When the connecting cover 91 is removed, the duck feathers on the connecting cover 91 will fall into the collecting frame 112 below, so that the duck feathers can be collected to prevent the duck feathers from floating down from a high altitude. When people need to clean the duck feathers in the collecting frame 112, the collecting frame 112 is moved to the right to take them out. The collecting frame 112 moves to the right to squeeze the limit block 114 and rotates clockwise. The second torsion spring 115 is twisted. When the collecting frame 112 is taken out and separated from the limit block 114, the duck feathers in the collecting frame 112 can be cleaned. After the duck feathers in the collecting frame 112 are cleaned, the collecting frame 112 is pushed back to the left onto the second connecting frame 111. In summary, when the connecting cover 91 is removed, the collecting frame 112 can collect the duck feathers in the connecting cover 91 to prevent the duck feathers from floating down from a high altitude.
