Description
Technical Field
[0001] The utility model is applicable to the technical field of laying hen breeding, and particularly relates to a closed heat-insulating device for a fan outlet of a laying hen breeding pen. Background Art
[0002] At present, laying hens refer to chickens that are raised specifically for laying eggs to supply eggs. Unlike broiler chickens, the main consideration in raising laying hens is how to improve the quality and egg production of eggs. The laying hen breeding houses mainly consider the living environment and feces discharge problems. Therefore, corresponding exhaust fans will be installed above the outer walls of the laying hen pens to increase the air circulation speed inside the pens, avoid the rapid growth of pathogens due to poor air circulation inside the pens, and affect the growth quality of laying hens.
[0003] However, there are now multiple sets of exhaust fans installed on the outer wall surface of the pen, and the vents of the exhaust fans always maintain a certain ventilation area, which results in the ventilation diameter of the vents being unable to be adjusted when the air is exhausted, so that when the air is exhausted, the air inside the pen will be exhausted together with the temperature, and it is impossible to conveniently control the temperature inside the pen. Therefore, we propose a closed insulation device for the fan outlet of the laying hen breeding pen. Utility Model Content
[0004] The main purpose of the utility model is to provide a closed heat preservation device for a fan outlet of a laying hen breeding pen, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A closed heat preservation device for a fan outlet of a laying hen breeding pen, comprising a pen body, a ventilation fan is fixedly installed on the outside of the pen body, and the number of ventilation fans is several groups, and a mounting frame is fixedly installed on the outside of each ventilation fan;
[0007] Both ends of the inner top of each installation frame are rotatably mounted with a rotating rod through bearings, a movable baffle is fixedly mounted between the outer sides of each rotating rod, and a transmission frame is fixedly mounted on the outer surface of each installation frame;
[0008] A first transmission rod is rotatably mounted on the top inner side of each transmission frame via a bearing, a second transmission rod is rotatably mounted on the bottom inner side of each transmission frame via a bearing, and the first transmission rod and the second transmission rod are fixedly connected to the rotating rod, a transmission sprocket is fixedly sleeved on the middle end surface of each of the first transmission rod and the second transmission rod, and a transmission chain ring is sleeved on the outer side of the transmission sprocket.
[0009] By adopting the above technical scheme, the position of the movable baffle can be driven to rotate under the meshing transmission action of the transmission sprocket and the transmission chain ring, and under the synchronous transmission action of the first transmission rod and the second transmission rod, thereby adjusting the discharge area of the air outlet on the side of the installation frame to avoid the air outlet area being too large, which will cause the internal temperature of the pen body to drop too quickly and affect the growth quality of laying hens.
[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly mounted on the outer top surface of each transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the outer top surface of the first transmission rod through a coupling.
[0011] By adopting the above technical solution, the driving structure of the servo motor can provide the power required for the synchronous rotation of multiple groups of first transmission rods and second transmission rods.
[0012] As an optional solution of the technical solution of the present application, sealing pads are fixedly bonded to the surfaces of both ends of the inner side of each installation frame, and the sealing pads are located on the outer side of the movable baffle.
[0013] By adopting the above technical solution, the sealing cushion structure can provide corresponding sealing protection treatment for the side edge of the movable baffle.
[0014] As an optional solution of the technical solution of the present application, the outer side of the transmission sprocket and the inner side of the transmission chain ring are meshed, and the transmission sprocket and the transmission chain ring are both rotatably located inside the transmission frame.
[0015] By adopting the above technical solution, the rationality of the transmission adjustment of the entire device is ensured through the meshing transmission action of the transmission sprocket and the transmission chain ring.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. The technical solution of the present application is a closed insulation device for a fan outlet of a laying hen breeding pen, in which multiple groups of movable baffles are rotatably installed inside a mounting frame by a rotating rod, and the first transmission rod and the second transmission rod are both connected to the rotating rod for transmission, combined with the meshing transmission action of the transmission sprocket and the transmission chain ring, so that when the servo motor is running and can drive the first transmission rod to rotate, the first transmission rod and the second transmission rod can rotate synchronously and in the same direction, thereby driving multiple groups of movable baffles to rotate synchronously and in the same direction inside the mounting frame, and adjusting the discharge area of the air outlet on the side of the mounting frame by the movable baffles by adjusting the inclination of the multiple groups of movable baffles, so as to avoid the air outlet area being too large, resulting in the temperature inside the pen body dropping too fast and affecting the growth quality of laying hens.
[0018] 2. The technical solution of the present application is a closed insulation device for the fan outlet of a laying hen breeding pen. By arranging sealing pads on both sides of the inside of the installation frame, combined with the sealing effect of the sealing pads on the outer side of the movable baffle, the upper and lower ends of the movable baffle can be sealed to avoid further reducing the air flow area between the installation frame and the outside when the movable baffle is fully vertically set, and further reducing the rate of temperature drop inside the pen.

DETAILED DESCRIPTION
[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a closed heat preservation device for a fan outlet of a laying hen breeding pen, wherein a ventilation fan 11 is fixedly installed on the outside of a pen body 1, and the number of the ventilation fans 11 is several groups, and the operation of the ventilation fans 11 can provide the required assistance for the air flow inside the pen body 1.
[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a servo motor 27 is fixedly mounted on the outer top surface of each transmission frame 21, and the side of the transmission shaft of the servo motor 27 is fixedly connected to the outer top surface of the first transmission rod 24 through a coupling.
[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), each ventilation fan 11 is fixedly connected to the outside of a mounting frame 2, and a transmission frame 21 is fixedly installed on the outer surface of each mounting frame 2, and a first transmission rod 24 is rotatably installed on the top of the inner side of each transmission frame 21 through a bearing, and a second transmission rod 28 is rotatably installed on the bottom of the inner side of each transmission frame 21 through a bearing, and the first transmission rod 24 and the second transmission rod 28 are fixedly connected to the rotating rod 22, and a transmission sprocket 25 is fixedly sleeved on the middle end surface of each first transmission rod 24 and the second transmission rod 28, and a transmission chain ring 26 is sleeved on the outer side of the transmission sprocket 25, and the outer side of the transmission sprocket 25 is meshed with the inner side of the transmission chain ring 26, and the transmission sprocket 25 and the transmission chain ring 26 are both rotatably located inside the transmission frame 21.
[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), both ends of the inner top of each mounting frame 2 are rotatably mounted with a rotating rod 22 through a bearing, and a movable baffle 23 is fixedly mounted between the outer sides of each rotating rod 22.
[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), sealing pads 3 are fixedly bonded to the inner and outer surfaces of both ends of each mounting frame 2, and the sealing pads 3 are located outside the movable baffle 23.
[0028] During operation, when the temperature of the outdoor environment is too low and the flow rate of the air between the enclosure body 1 and the outside air needs to be reduced, the servo motor 27 is turned on through an external control switch to make it run and drive the first transmission rod 24 and the transmission sprocket 25 sleeved on its surface to rotate. Combined with the meshing transmission of the transmission sprocket 25 and the transmission chain ring 26, the plurality of second transmission rods 28 can rotate synchronously with the rotation of the first transmission rod 24, thereby driving the rotating rod 22 and the movable baffle 23 on its surface to rotate synchronously inside the installation frame 2, changing the movable baffle 23. The inclination inside the mounting frame 2 allows the movable baffle 23 to be in a relatively vertical state, so that the movable baffle 23 can adjust the shielding area of the air outlet on the side of the mounting frame 2, thereby preventing the air flow rate inside the pen from being too fast, which causes the internal temperature to drop too fast and affects the growth quality of laying hens. Conversely, when it is necessary to speed up the flow of air inside the pen body 1, the movable baffle 23 can be rotated and adjusted to be in a horizontal position, thereby reducing the shielding area of the air outlet on the side of the mounting frame 2, thereby increasing the flow rate of air in the pen body 1.
