[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] Please refer to Figures 1-2 A ventilation device for a chicken house, comprising a ventilation cylinder 1 and a chicken house shed 2, the chicken house shed 2 is the wall of the chicken house shed, the chicken house shed 2 is usually composed of a tarpaulin and a steel structure frame, the ventilation cylinder 1 is fixedly installed on one side of the chicken house shed 2, and the ventilation cylinder 1 penetrates the chicken house shed 2 and is installed, a trench pipe 3 is fixedly installed at the middle bottom of the ventilation cylinder 1, the trench pipe 3 is installed outside the chicken house shed 2, an air inlet is formed at one end of the ventilation cylinder 1, the number of the air inlets is three, an adjustment device 4 is fixedly installed inside the ventilation cylinder 1, motors 5 are fixedly installed at the top of the ventilation cylinder 1 in a circular ring shape, and the number of the adjustment devices 4 corresponds to the number of the motors 5.
[0025] When the device is used for ventilating the chicken house, the air entering through the air inlet is divided by the shunt plate 11. The air entering through the air inlet is first filtered by the filter element 12 to remove harmful gases and odors in the air, and then the air is divided by the shunt plate 11. Part of the air enters the chicken shed 2 through the upper part of the shunt plate 11, and the other part of the air enters the trench pipe 3 through the lower part of the shunt plate 11, thereby achieving shunt ventilation.
[0026] By setting the three-sided adjusting device 4, when the device needs to be ventilated, the wind direction can be evenly borrowed through the corresponding adjusting device 4 regardless of the direction of the wind. For example, when the wind flows horizontally, the adjusting device 4 on one side of the end of the ventilation cylinder 1 is opened, so that the wind enters the inside of the ventilation cylinder 1 from one end of the ventilation cylinder 1. When the wind flows vertically, the adjusting devices 4 on the corresponding sides of the two sides of the end of the ventilation cylinder 1 are opened, so that the wind enters the inside of the ventilation cylinder 1 from the side.
[0027] Please refer to Figures 1-2 The inside of the ventilation cylinder 1 is fixedly installed with a shunt plate 11 above the trench pipe 3. The shunt plate 11 is arc-shaped, so that the wind in the inside of the ventilation cylinder 1 is divided by the shunt plate 11. Half of the wind enters the inside of the chicken shed from the upper half of the ventilation cylinder 1, and the other half of the wind enters the inside of the trench pipe 3 through the lower part of the shunt plate 11. The inside of the ventilation cylinder 1 is fixedly installed with a filter element 12 on one side of the shunt plate 11.
[0028] By setting the shunt plate 11 and the filter element 12, the air is divided after being filtered, so that the air enters the inside of the chicken shed from the middle and the bottom of the chicken shed respectively, so that the air quality near the ground in the inside of the chicken shed is the same as the air quality of the upper layer of the chicken shed.
[0029] Please refer to Figures 1-2 The top of the trench pipe 3 is provided with a concentrating cylinder. A rectangular slot is formed at the connection between the bottom of the ventilation cylinder 1 and the trench pipe 3. The shape of the trench pipe 3 is circular, the top of the concentrating cylinder is rectangular, and the bottom of the concentrating cylinder is circular. The wind entering the inside of the trench pipe 3 from the shunt plate 11 is concentrated by the concentrating cylinder and enters the inside of the trench pipe 3. The outer circle of one end of the trench pipe 3 is evenly provided with air holes 31. The end where the air holes 31 are located is located in the inside of the chicken shed 2.
[0030] The air outlet of the ventilation cylinder 1 is located in the middle of the chicken shed 2, and the air holes 31 are located in the lower layer of the chicken shed. The air quality is improved by air convection, the temperature difference between the upper and lower layers in the inside of the chicken shed is reduced, and the air flow in the lower layer of the chicken shed is accelerated by setting the position of the air outlet. Generally, chicken excrement falls on the ground. Due to the accumulation of excrement, the air quality in the lower layer of the chicken shed is very poor. The prior art only ventilates the middle part of the chicken shed, which leads to poor ventilation effect at the bottom and affects the survival quality of the chickens.
[0031] Please refer to Figures 1-4The adjusting device 4 comprises a baffle and a clasp 41, the baffle is rotationally installed between the inner wall of the air inlet, the baffle is uniformly installed in a linear array at the air inlet, and the baffle is fixedly installed with the clasp 41 on one side.
[0032] By uniformly arranging the connection between the baffle and the motor 5, the motor 5 adjusts the inclination angle of the baffle, the air inlet of the chicken house can be adjusted by controlling the inclination angle of the baffle, thereby controlling the size of the air inlet, when the odor in the chicken house is heavy, the baffle is completely opened, and the air flow in the chicken house reaches the maximum, when the chicken needs to rest and sleep at night, the angle of the baffle is adjusted to be small, so that the air inlet is small, and the sleep of the chicken is avoided.
[0033] Please refer to Figures 1-4 The output shaft end of the motor 5 is fixedly connected with a winder 51, the winder 51 is provided with a pull rope 52 wound outside, one end of the pull rope 52 is fixedly connected to one side of the lowermost baffle, the pull rope 52 passes through the clasp 41, and the pull rope 52 is provided with a knot 53 below the clasp 41. The outer diameter of the knot 53 is larger than the inner diameter of the clasp 41, and the knot 53 cannot pass through the clasp 41.
[0034] By starting the motor 5, the motor 5 drives the winder 51 to rotate through the output shaft, when the winder 51 rotates, the pull rope 52 located outside the winder 51 is wound, so that the pull rope 52 located at the bottom of the adjusting device 4 is pulled, and the knot 53 cannot slide below the clasp 41 due to the position limitation of the clasp 41. The pull rope 52 drives the baffle to rotate upwards between the air inlets, so that air can enter the inside of the ventilation duct 1 from between the baffles, when the motor 5 drives the driving shaft to rotate in reverse, the winder 51 releases the wound pull rope 52, and since the baffle is not pulled by the pull rope 52, the baffle rotates downwards, and the baffle is closed.
[0035] Working principle: when the user needs to ventilate the inside of the chicken house, observe the wind direction, open the adjustment device 4 matched with it, according to the inside condition of the chicken house or the wind size, select the angle of the wind shield, start the motor 5, the motor 5 drives the line winder 51 to rotate, the line winder 51 winds the pull rope 52, after the pull rope 52 is wound, the bottom wind shield of the adjustment device 4 is pulled to rotate upward, the upper wind shield is limited by the snap ring 41 and the knot 53, so it rotates upward together with the pull rope 52, realizes opening the wind shield, makes the air enter the inside of the ventilation cylinder 1 through the wind shield, after the air enters the inside of the ventilation cylinder 1, it is filtered by the filter element 12 first, filters the harmful gas and odor in the air, then the air is divided by the flow distribution plate 11, the air above the flow distribution plate 11 enters the middle part of the chicken house, accelerates the air flow of the whole environment in the chicken house, the air below the flow distribution plate 11 enters the inside of the ditch pipe 3 through the concentration cylinder, then is discharged from the air hole 31 through the bending part, the air hole 31 is located in the lower layer of the chicken house, accelerates the air flow of the lower layer of the chicken house.
