Description

Technical Field

[0001] This invention relates to the field of egg-laying hen farming technology, specifically to an automatic temperature control device for egg-laying hen farming. Background Technology

[0002] The automatic temperature control system for laying hens can accurately sense temperature changes inside the chicken house and automatically adjust it to create a stable and suitable growth environment for the hens. In cold seasons, the system can automatically activate heating equipment to raise the temperature inside the house, preventing the hens from freezing due to low temperatures and reducing problems such as decreased egg production and disease caused by cold, thus ensuring the healthy growth of the hens. In hot weather, it can promptly activate ventilation and cooling devices to lower the temperature inside the house, preventing heat stress reactions in the hens, such as rapid breathing and reduced feed intake, maintaining the normal physiological functions and metabolism of the hens, and ensuring their continuous and stable egg production. At the same time, a stable temperature environment helps reduce the production and accumulation of harmful gases in the chicken house, improves air quality, and reduces the probability of respiratory diseases. The automatic temperature control system can also reduce human operation errors and labor intensity, improve breeding efficiency, provide reliable protection for laying hen breeding, and help farmers achieve efficient and high-quality laying hen breeding.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In the scheme of this application: 1. To address the problems of incomplete temperature monitoring, limited adjustment methods, and difficulty in accurately controlling heat distribution in existing breeding facilities, this application proposes a method that uses six temperature-sensing resistors to comprehensively and accurately monitor the ambient temperature of the breeding facility. The main control unit, combined with a microprocessor equipped with 4G and a PID algorithm, intelligently starts the external gas burner to achieve efficient heating. Simultaneously, it starts a second motor to drive components such as a bidirectional screw, which can flexibly adjust the height of the radiant tube body, thereby achieving precise control of the heat inside the breeding facility, creating a more suitable temperature environment for the animals and improving breeding efficiency. 2. To address the problems of inconvenient heat distribution adjustment and difficulty in precise control of heating effect in existing breeding room heating devices, this application proposes to install a gas radiant tube.

The first motor is activated to drive the turntable to rotate, which moves the rack and pinion via the connecting rod and connecting column, driving the external gear to rotate. This, in turn, causes the rotating shaft to open and close the baffle for adjustment. The air intake angle and volume can be flexibly adjusted according to different seasons, achieving precise temperature control in the breeding house and improving the quality of the breeding environment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides an automatic temperature control device for egg-laying hen farming, such as... Figure 1 - Figure 7 As shown, the system includes a breeding house 1, a door 2 hinged to the front of the breeding house 1, a rain shelter 3 fixedly connected to the top of the breeding house 1, an adjustment component 4 installed on the top of the breeding house 1, a temperature control component 5 installed inside the breeding house 1, and a data collection component 6 installed inside the breeding house 1. The adjustment component 4 includes an air inlet box 401, which is fixedly connected to the top of the breeding house 1. A rotating shaft 402 is installed inside the air inlet box 401, a guide plate 403 is fixedly connected to the outer wall of the rotating shaft 402, and an external gear 404 is fixedly connected to the outer wall of the rotating shaft 402. A gear 404 has a gear rack 405 meshing with its outer wall. A connecting post 406 is fixedly connected to one side of the gear rack 405. A fixing sleeve 407 is slidably connected to the outer wall of the connecting post 406, and the fixing sleeve 407 is fixedly connected to one side of the air inlet box 401. A connecting rod 408 is hinged to one end of the connecting post 406, and a turntable 409 is hinged to one end of the connecting rod 408. A fixing block 410 is fixedly connected to the top of the breeding house 1. A limit rod 411 is fixedly connected to one side of the fixing block 410, and a sleeve rod 412 is slidably connected to the outer wall of the limit rod 411. A fan 413 is fixedly connected to the top of the breeding room 1. A protective shell 7 is also fixedly connected to the top of the breeding room 1. A motor base 8 is fixedly connected inside the protective shell 7. A first motor 414 is fixedly connected inside the motor base 8, and the output end of the first motor 414 is fixed to the inside of the turntable 409. When the fan 413 is started, it can exhaust the stale air inside the breeding room 1 through the ventilation holes 601 on both sides, and allow fresh air to enter through the air inlet box 401. By starting the first motor 414 on the motor base 8, the first motor 414 can be activated. The motor 414 can drive the turntable 409 to adjust its angle, so that the turntable 409 can drive the connecting column 406 on the connecting rod 408 to move, which in turn drives the rack 405 to move, which in turn drives the external gear 404 to rotate, which in turn drives the rotating shaft 402 to rotate, which in turn drives the guide plate 403 to adjust its opening and closing angle, so as to adjust the air intake angle and use the appropriate air intake volume in the appropriate season for more precise temperature control.

[0020] Further such as Figure 6As shown, the turntable 409 forms a movable structure with the connecting rod 408 and the connecting column 406. One end of the connecting rod 408 is hinged to one side of the turntable 409, and the other end of the connecting rod 408 is hinged to one end of the connecting column 406. This strengthens the connection between the turntable 409 and the connecting rod 408, allowing the turntable 409 to rotate and drive the connecting rod 408 to push the connecting column 406 to move.

[0021] Further such as Figure 6 As shown, the connecting column 406 forms a rotating structure with the external gear 404 via the rack 405, and one side of the rack 405 is fixedly connected to one end of the connecting column 406, and the outer wall of the rack 405 meshes with the outer wall of the external gear 404, which strengthens the connection effect between the connecting column 406 and the rack 405, so that the connecting column 406 can drive the rack 405 to drive the external gear 404 to rotate.

[0022] Further such as Figure 6 As shown, the external gear 404 forms a rotating structure with the guide plate 403 via the rotating shaft 402. The outer wall of the rotating shaft 402 is fixedly connected to the inner wall of the external gear 404, and the outer wall of the rotating shaft 402 is fixedly connected to the interior of the guide plate 403. This strengthens the connection between the external gear 404 and the rotating shaft 402, allowing the external gear 404 to drive the rotating shaft 402 and thus drive the guide plate 403 to adjust its angle.

[0023] In a further preferred embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the temperature control component 5 includes a gas radiant tube inlet 501, which is fixed to one side of the breeding room 1. One end of the gas radiant tube inlet 501 is fixedly connected to a radiant tube body 502, and one end of the radiant tube body 502 is fixedly connected to a gas radiant tube exhaust port 503. A top plate 504 is fixedly connected to the top of the radiant tube body 502. A movable rod 505 is hinged to the top of the top plate 504, and a sliding sleeve 506 is hinged to the top of the movable rod 505. A sliding rod 507 is slidably connected inside the sliding sleeve 506. A side plate 508 is fixedly connected to one side of the sliding rod 507, and a threaded sleeve 509 is fixedly connected inside the side plate 508. A double-ended screw 510 is threaded inside the threaded sleeve 509, and a second motor 511 is fixedly connected to one end of the double-ended screw 510. A reinforcing plate is fixedly connected to the outer wall of the second motor 511. 512, the external gas burner is started, and hot gas is drawn into the gas radiant tube inlet 501, so that the heat is contained within the radiant tube body 502, and the radiant tube body 502 is heated, thereby raising the temperature inside the breeding room 1. At the same time, the second motor 511 is started, which drives the bidirectional screw 510 to rotate within the threaded sleeve 509. The threaded sleeve 509 drives the side plate 508 to rotate, and the two side plates 508 can slide along the outer wall of the slide rod 507 by the sliding sleeves 506 on both sides. The sliding sleeves 506 drive the movable rod 505 to move, and the movable rod 505 can adjust the height of the radiant tube body 502 on the top plate 504, thereby adjusting the height of the radiant tube body 502 to control the heat inside the breeding room 1.

[0024] Further such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the gas radiant tube inlet 501 is integrated with the gas radiant tube body 502 and the gas radiant tube exhaust port 503. The gas radiant tube exhaust port 503 is located between the gas radiant tube inlet 501 and the gas radiant tube exhaust port 503, which strengthens the connection effect of the gas radiant tube inlet 501 through the radiant tube body 502. The gas burner allows hot gas to flow through the gas radiant tube inlet 501 into the radiant tube body 502 for heating, and the gas is discharged through the gas radiant tube exhaust port 503.

[0025] Further such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the sliding sleeve 506 forms a hinged structure with the top plate 504 through the movable rod 505, and the two ends of the movable rod 505 are respectively hinged to the sliding sleeve 506 and the top plate 504, which strengthens the connection effect between the sliding sleeve 506 and the movable rod 505. This allows the sliding sleeve 506 to move when it moves, and also allows the top plate 504 to be adjusted to different heights.

[0026] Further such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the second motor 511 forms a threaded structure with the threaded sleeve 509 via the bidirectional screw 510. The outer diameter of the bidirectional screw 510 matches the inner diameter of the threaded sleeve 509, and the inner wall of the threaded sleeve 509 fits against the outer wall of the bidirectional screw 510, which enhances the connection between the second motor 511 and the bidirectional screw 510. This allows the second motor 511 to rotate within the threaded sleeve 509 by driving the bidirectional screw 510, facilitating the movement of the side plate 508.

[0027] In a further preferred embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the acquisition component 6 includes a ventilation hole 601, which is located on the outer wall of the breeding room 1. The main control unit 602 is fixedly connected inside the breeding room 1, and a temperature measuring resistor 603 is fixedly connected inside the breeding room 1. The temperature of the environment in the breeding room 1 can be accurately monitored from all directions through the temperature measuring resistors 603 on the six sides inside the breeding room 1.

[0028] Further such as Figure 2 and Figure 3 As shown, the main control unit 602 includes a microprocessor and a communication module, with a built-in PID control algorithm. There are multiple temperature measuring resistors 603, which are fixed on the six sides of the breeding room 1. By setting up the microprocessor and communication module, efficient temperature control and remote intelligent management can be achieved. Furthermore, temperature measuring resistors 603 are set on all six sides of the breeding room 1, which can measure the temperature inside the breeding room 1 from all directions.

[0029] Working Principle: During use, the temperature of the breeding room 1 can be accurately monitored from all directions by the temperature measuring resistors 603 on six sides. When temperature adjustment is required, the main control unit 602, through a microprocessor equipped with 4G and PID algorithm, starts the external gas burner, allowing hot air to enter the gas radiant tube inlet 501 and the heat to be concentrated in the radiant tube body 502, thus heating the interior of the breeding room 1. Simultaneously, the second motor 511 is started, which drives the bidirectional screw 510 to rotate within the threaded sleeve 509. The threaded sleeve 509 then drives the side plates 508 to rotate, allowing the two side plates 508 to slide along the outer wall of the sliding rod 507 via the sliding sleeves 506 on both sides. The sliding sleeves 506 then drive the movable rod 505 to move, which in turn moves the radiant tube body on the top plate 504. 502 is height-adjusted to control the heat inside the breeding room 1. Additionally, during ventilation, the fan 413 is activated to expel stale air from the ventilation holes 601 on both sides of the breeding room 1, while fresh air enters through the air inlet box 401. Activating the first motor 414 on the motor base 8 adjusts the angle of the turntable 409, which in turn moves the connecting column 406 on the connecting rod 408. The connecting column 406 moves the rack 405, which in turn rotates the external gear 404. The external gear 404 then rotates the rotating shaft 402, which in turn opens and closes the guide plate 403 to adjust the air intake angle. Appropriate air intake volume is then used in suitable seasons for more precise temperature control.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
