[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-6 The present invention provides the following technical solution: a ventilation device for pig breeding sheds, including a first ventilation pipe 1, a filter plate 2 movably installed on one side of the first ventilation pipe 1, a second ventilation pipe 5 connected to the side of the first ventilation pipe 1 away from the filter plate 2, a heating component 3 installed inside the first ventilation pipe 1, and a closing component 4 installed between the first ventilation pipe 1 and the second ventilation pipe 5. The heating assembly 3 includes a mounting bracket 31, which is fixedly disposed inside the first vent pipe 1. A mounting ear plate 32 is fixedly attached to one side surface of the mounting bracket 31. A mounting bolt 33 is disposed inside the mounting ear plate 32. A plurality of heating plates 34 are disposed inside the mounting bracket 31. A bearing block 36 is disposed inside the heating plate 34. An electric heating wire 35 is installed inside the bearing block 36. A cleaning assembly 37 is disposed on the outside of the mounting bracket 31.

[0018] By adopting the above technical solution, the second ventilation pipe 5 of the ventilation device for pig breeding sheds disclosed in Chinese Patent Application No. 202222325628.1 is equipped with a motor and suction blades. When the heating component 3 is used, heat is generated by the heating wire 35 inside the support block 36 and transferred to the surface of the heating plate 34 through the support block 36. External air enters the first ventilation pipe 1 through the filter plate 2. When it passes through the heating plate 34, the air is heated by the heating plate 34. After the air temperature is increased, the motor and suction blades inside the second ventilation pipe 5 work together to send the heated air into the breeding shed, thereby completing the air heating work.

[0019] Specifically, a fixing frame is installed on the side of the mounting bracket 31 near the filter plate 2. The fixing frame has a stop block inside for rotation, and a rotating shaft connects the fixing frame and the stop block.

[0020] By adopting the above technical solution, before the external air comes into contact with the heating plate 34, it will first come into contact with the baffle inside the fixing frame. The baffle blocks the external air, and the external air can push the baffle to rotate. At the same time, the air flow rate is reduced, so that the external air can have a longer contact time with the heating plate 34, thus ensuring the air heating effect.

[0021] Specifically, a limiting plate is fixedly installed on the top of the mounting bracket 31, and fixing bolts are installed at both ends of the limiting plate.

[0022] By adopting the above technical solution, when a single heating plate 34 is damaged, the limiting plate can be removed by fixing bolts to replace the single heating plate 34. After replacement, the fixing bolts and the limiting plate are used to install the heating plate, thereby improving the utilization rate of materials.

[0023] Specifically, the cleaning component 37 includes a mounting block 371, on which the outer surface of the mounting bracket 31 is fixedly disposed. A drive motor 372 is fixedly mounted at one end of the mounting block 371. A threaded rod 373 is fixedly connected to the output end of the drive motor 372. A moving block 376 is threadedly connected to the surface of the threaded rod 373. A cylinder 375 is fixedly mounted on the top surface of the moving block 376. A cleaning brush 374 is connected to the output end of the cylinder 375.

[0024] By adopting the above technical solution, dust will accumulate on the air intake side of the heating plate 34 during long-term use. If a large amount of dust accumulates, it will affect the air heating efficiency. At this time, the drive motor 372 can be started, which drives the threaded rod 373 to rotate, further causing the moving block 376 to drive the cylinder 375 and the cleaning brush 374 to move. By moving the cleaning brush 374 on one side of the heating plate 34, one side surface of the heating plate 34 can be cleaned. The cleaning force of the cleaning brush 374 on the heating plate 34 can be adjusted by the cylinder 375, thereby ensuring the cleaning effect.

[0025] Specifically, a limiting groove is provided on the top surface of the movable block 376, and a guide rod is fixedly installed inside the limiting groove. A guide block is fixedly connected to the bottom of the cleaning brush 374.

[0026] By adopting the above technical solution, when the cylinder 375 pushes the cleaning brush 374 to move, the guide block at the bottom of the cleaning brush 374 will slide synchronously on the surface of the guide rod, thereby improving the stability of the movement of the cleaning brush 374.

[0027] In this embodiment, the second ventilation pipe 5 of the ventilation device for a pig farm shed disclosed in Chinese Patent Application No. 202222325628.1 already has a motor and suction blades installed inside. When the heating component 3 is used, heat is generated by the heating wire 35 inside the support block 36, and the heat is transferred to the surface of the heating plate 34 through the support block 36. External air enters the first ventilation pipe 1 through the filter plate 2. When it passes through the heating plate 34, the heating plate 34 heats the air. After the air temperature is increased, the motor and suction blades installed inside the second ventilation pipe 5 work together to deliver the heated air into the shed, thus completing the air heating work. Before the external air comes into contact with the heating plate 34, it first comes into contact with the baffle inside the fixing frame. The baffle blocks the external air, and the external air can push the baffle to rotate, while reducing the air flow rate, so that the external air can have a longer contact time with the heating plate 34. To ensure effective air heating, when a single heating plate 34 is damaged, the limiting plate can be removed using the fixing bolts to replace the single heating plate 34. After replacement, the fixing bolts and limiting plate are used to install the heating plate, thereby improving material utilization. During long-term use, dust will accumulate on the air intake side of the heating plate 34. If a large amount of dust accumulates, it will affect the air heating efficiency. At this time, the drive motor 372 can be started, which drives the threaded rod 373 to rotate, further causing the moving block 376 to drive the cylinder 375 and the cleaning brush 374 to move. By moving the cleaning brush 374 on one side of the heating plate 34, one side surface of the heating plate 34 can be cleaned. The cleaning force of the cleaning brush 374 on the heating plate 34 can be adjusted by the cylinder 375, thereby ensuring the cleaning effect. When the cylinder 375 pushes the cleaning brush 374 to move, the guide block at the bottom of the cleaning brush 374 will slide synchronously on the surface of the guide rod, thereby improving the stability of the movement of the cleaning brush 374.

[0028] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the closing component 4 includes a storage plate 41, which is fixedly mounted between the first vent pipe 1 and the second vent pipe 5. A storage cavity 44 is provided inside the storage plate 41. A bidirectional screw 42 is rotatably provided on the top of the storage cavity 44, and a slide rod 43 is fixedly provided on the bottom of the bidirectional screw 42. A baffle 46 is provided inside the storage cavity 44. A threaded block 47 is fixedly connected to the top surface of the baffle 46, and a sliding plate 45 is fixedly connected to the bottom surface of the baffle 46.

[0029] By adopting the above technical solution, when using the closing component 4, if there are pollutants in the external environment, the handwheel can be used to drive the bidirectional screw 42 to rotate, thereby causing the threaded block 47 to drive the baffle 46 to move closer to each other inside the receiving plate 41. The sliding plate 45 at the bottom of the baffle 46 slides synchronously on the surface of the sliding rod 43, which improves the stability of the movement of the baffle 46. When the sealing blocks on both sides are in close contact, the closing work is completed.

[0030] Specifically, a sealing block is fixed on the inner surface of the baffle 46, and sealing frames are provided on both sides of the storage plate 41.

[0031] By adopting the above technical solution, the sealing block can ensure the isolation effect of the baffle 46 in isolating pollutants, and the sealing frame can prevent poor sealing at the connection between the first vent pipe 1 and the second vent pipe 5 and the component, thus ensuring that the breeding environment inside the breeding shed is not affected.

[0032] In this embodiment, when using the closing component 4, if there are pollutants in the external environment, the handwheel can be used to drive the bidirectional screw 42 to rotate, thereby causing the threaded block 47 to drive the baffle 46 to move closer to each other inside the storage plate 41. The sliding plate 45 at the bottom of the baffle 46 slides synchronously on the surface of the sliding rod 43, which improves the stability of the movement of the baffle 46. When the sealing blocks on both sides are in close contact, the closing work is completed. The sealing blocks can ensure the isolation effect of the baffle 46 in isolating pollutants. The sealing frame avoids the phenomenon of poor sealing effect at the connection between the first vent pipe 1 and the second vent pipe 5 and the component, ensuring that the breeding environment inside the breeding shed is not affected.

[0033] The structure and operating principle of the first ventilator 1, filter plate 2, and second ventilator 5 in this utility model have been disclosed in a ventilation device for pig farming sheds disclosed in Chinese patent application number 202222325628.1.

[0034] The working principle and usage process of this utility model are as follows: In a ventilation device for a pig farm shed disclosed in Chinese Patent Application No. 202222325628.1, the second ventilation pipe 5 is equipped with a motor and suction blades. When the heating component 3 is used, heat is generated by the heating wire 35 inside the support block 36, and the heat is transferred to the surface of the heating plate 34 through the support block 36. External air enters the first ventilation pipe 1 through the filter plate 2. When it passes through the heating plate 34, the air is heated by the heating plate 34. After the air temperature is increased, the motor and suction blades inside the second ventilation pipe 5 work together to deliver the heated air into the shed, thus completing the air heating process. Before contacting the heating plate 34, the external air first contacts the baffle inside the fixing frame. The baffle blocks the external air, and the external air can push the baffle to rotate, while reducing the airflow velocity, thus increasing the contact time between the external air and the heating plate 34. The longer heating time ensures better air heating performance. When a single heating plate 34 is damaged, the limiting plate can be removed by fixing bolts to replace the single heating plate 34. After replacement, the fixing bolts and limiting plate are used together for installation, thereby improving material utilization. During long-term use, dust will accumulate on the air intake side of the heating plate 34. If a large amount of dust accumulates, it will affect the air heating efficiency. At this time, the drive motor 372 can be started. The drive motor 372 drives the threaded rod 373 to rotate, which in turn causes the moving block 376 to drive the cylinder 375 and the cleaning brush 374 to move. The cleaning brush 374 moves on one side of the heating plate 34 to clean one side of the heating plate 34. The cylinder 375 can adjust the cleaning force of the cleaning brush 374 on the heating plate 34 to ensure the cleaning effect. When the cylinder 375 pushes the cleaning brush 374 to move, the guide block at the bottom of the cleaning brush 374 will slide synchronously on the surface of the guide rod, thereby improving the stability of the movement of the cleaning brush 374. When using the closing component 4, if there are pollutants in the external environment, the handwheel can be used to drive the bidirectional screw 42 to rotate, thereby causing the threaded block 47 to move the baffle 46 closer together inside the storage plate 41. The sliding plate 45 at the bottom of the baffle 46 slides synchronously on the surface of the sliding rod 43, which improves the stability of the movement of the baffle 46. When the sealing blocks on both sides are in close contact, the closing work is completed. The sealing blocks can ensure the isolation effect of the baffle 46 from pollutants. The sealing frame avoids the phenomenon of poor sealing effect at the connection between the first vent pipe 1 and the second vent pipe 5 and the component, ensuring that the breeding environment inside the breeding shed is not affected.
