Through the installation mechanism and auxiliary mechanism, it solves the problem that the frequent vibrations generated during the operation of the device can cause the parts inside the device to loosen, making the device unable to be used normally and increasing the cost of use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a ventilation structure for cattle sheds, including an installation plate, and a first positioning plate is slidably connected to the outer wall of the installation plate;

[0007] The outer wall of the mounting plate is provided with a mounting mechanism, which includes a first fan. The outer wall of the first fan is fixedly connected to the inner wall of the first positioning plate. Several connecting blocks are fixedly connected to the outer wall of the first fan. Limiting blocks are slidably connected to the outer wall of the connecting blocks. A spring is fixedly connected to the inner wall of the limiting block. A pressure plate is fixedly connected to the outer wall of the spring away from the limiting block. A first positioning rod is rotatably connected to the outer wall of the pressure plate. A limiting rod is rotatably connected to the outer wall of the first positioning rod. Several limiting grooves are opened on the inner wall of the limiting block. Several pressure springs are fixedly connected to the inner wall of the limiting block. A first locking block is fixedly connected to the outer wall of the pressure spring away from the limiting block.

[0008] Furthermore, the outer wall of the limiting block is slidably connected to the inner wall of the mounting plate, the outer wall of the first positioning rod is engaged with the inner wall of the limiting block, the inner wall of the limiting groove is slidably connected to the outer wall of the first locking block, and an auxiliary mechanism is provided on the inner wall of the first positioning plate.

[0009] Furthermore, the auxiliary mechanism includes a second positioning plate, the outer wall of the second positioning plate being rotatably connected to the outer wall of the first positioning plate, and a plurality of second positioning rods being fixedly connected to the inner wall of the second positioning plate on the side near the first positioning plate.

[0010] Furthermore, a flow-blocking plate is rotatably connected to the inner wall of the first positioning plate, and a sliding groove is provided on the inner wall of the flow-blocking plate. The inner wall of the sliding groove is slidably connected to the outer wall of the second positioning rod.

[0011] Furthermore, the outer wall of the second positioning plate is fixedly connected with several elastic clamping plates, and the outer wall of the first positioning plate is fixedly connected with several second clamping blocks, the outer wall of the second clamping blocks engaging with the outer wall of the elastic clamping plates.

[0012] Furthermore, a second fan is fixedly connected to the inner wall of the first positioning plate on the side away from the second positioning plate, a plurality of first connecting shafts are fixedly connected to the outer wall of the second fan, a plurality of connecting rods are fixedly connected to the outer wall of the first connecting shafts, and gears are rotatably connected to the outer wall of the ends of the plurality of connecting rods away from the first connecting shafts.

[0013] Furthermore, a rack meshes with the outer wall of the gear, the outer wall of the rack is fixedly connected to the inner wall of the first positioning plate, and a second connecting shaft is fixedly connected to the outer wall of the gear, the outer wall of the second connecting shaft being rotatably connected to the inner wall of the connecting rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a limiting block and a limiting rod, causes the first positioning rod to move during the movement of the pressure plate. At the same time, the limiting rod restricts the movement direction of the first positioning rod. This allows the limiting rod to push the first positioning rod to rotate, and the front end of the limiting rod will insert into the limiting groove inside the limiting block. The first positioning rod pushes the first locking block to move while squeezing the pressure spring. The elasticity of the pressure spring pushes the first locking block to lock the limiting rod. This achieves the goal of changing the rotation direction of the limiting rod and locking the limiting block by the limiting rod, preventing the problem of loosening of internal parts due to frequent vibrations during operation, which would cause the device to malfunction and increase the cost of use.

[0017] 2. This utility model incorporates a scraper and a filter plate. The rotation of the connecting rod drives the gear to move along the inside of the first positioning plate. Simultaneously, the gear meshes with the rack. Therefore, during the movement of the gear, the rack pushes multiple gears to rotate around the connecting rod. This causes the gear to rotate the second connecting shaft, which in turn drives the scraper to move along the outside of the filter plate, thus scraping away the dust on the surface of the filter plate. This achieves the goal of increasing the cleaning force of the filter plate surface by rotating the gear and driving the scraper to rotate, and increasing the cleaning area by rotating the connecting rod and moving the scraper. This prevents the problem of dust accumulating at the air outlet during long-term use of the device, which reduces airflow and leads to a decrease in the ventilation efficiency of the device.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a ventilation structure for a cattle shed, including an installation plate 1, and a first positioning plate 101 is slidably connected to the outer wall of the installation plate 1;

[0029] An installation mechanism 2 is provided on the outer wall of the mounting plate 1. The installation mechanism 2 includes a first fan 201, which blows air out of the cowshed. The outer wall of the first fan 201 is fixedly connected to the inner wall of the first positioning plate 101. Several connecting blocks 202 are fixedly connected to the outer wall of the first fan 201. Limiting blocks 203 are slidably connected to the outer wall of the connecting blocks 202. By installing the first fan 201 inside the first positioning plate 101, the multiple connecting blocks 202 are driven to insert into the limiting blocks 203 on the other side of the mounting plate 1. A spring 204 is fixedly connected to the inner wall of the limiting block 203. A pressure plate 205 is fixedly connected to the outer wall of the end of the spring 204 away from the limiting block 203. The connecting blocks 202 push the pressure plate 205 inside the limiting block 203 to compress the spring 204, thereby relieving pressure using the spring 204. A first positioning rod 206 is rotatably connected to the outer wall of the pressure plate 205. A limiting rod 207 is rotatably connected to the outer wall of the first positioning rod 206. The movement of 205 causes the first positioning rod 206 to move, and the limiting rod 207 restricts the movement range of the first positioning rod 206 and pushes the first positioning rod 206 to rotate. The inner wall of the limiting block 203 has several limiting grooves 208, and several pressure springs 210 are fixedly connected to the inner wall of the limiting block 203. A first locking block 209 is fixedly connected to the outer wall of the end of the pressure spring 210 away from the limiting block 203. The first positioning rod 206 is inserted into the connecting block 202 by rotation. Within the limiting groove 208, the first positioning rod 206 pushes the first locking block 209 while simultaneously squeezing the pressure spring 210. The elasticity of the pressure spring 210 pushes the first locking block 209 to be locked by the limiting rod 207. The outer wall of the limiting block 203 is slidably connected to the inner wall of the mounting plate 1. The outer wall of the first positioning rod 206 is engaged with the inner wall of the limiting block 203. The inner wall of the limiting groove 208 is slidably connected to the outer wall of the first locking block 209. An auxiliary mechanism 3 is provided on the inner wall of the first positioning plate 101.

[0030] The auxiliary mechanism 3 includes a second positioning plate 301, the outer wall of which is rotatably connected to the outer wall of the first positioning plate 101. Several second positioning rods 302 are fixedly connected to the inner wall of the second positioning plate 301 near the first positioning plate 101. A flow-blocking plate 303 is rotatably connected to the inner wall of the first positioning plate 101. A groove 304 is formed on the inner wall of the flow-blocking plate 303, and the inner wall of the groove 304 is slidably connected to the outer wall of the second positioning rods 302. By rotating the second positioning plate 301, the second positioning rods 302 move along the inside of the groove 304, simultaneously pushing the flow-blocking plate 303 to rotate. The rotation of the multiple flow-blocking plates 303 blocks the outer side of the first fan 201. The area is fixed, thereby changing the airflow speed of the first fan 201. The outer wall of the second positioning plate 301 is fixedly connected with several elastic clamping plates 313, and the outer wall of the first positioning plate 101 is fixedly connected with several second clamping blocks 314. The outer wall of the second clamping block 314 engages with the outer wall of the elastic clamping plate 313. The rotation of the second positioning plate 301 drives the multiple elastic clamping plates 313 to move. Since the elastic clamping plate 313 is in contact with the second clamping block 314, the elastic clamping plate 313 will be squeezed and deformed by the second clamping block 314 as it moves, and will rebound to its original position by the elasticity of the elastic clamping plate 313 and clamp the second clamping block 314 again, thereby restricting the movement of the second positioning plate 301.

[0031] A second fan 305 is fixedly connected to the inner wall of the first positioning plate 101 away from the second positioning plate 301. Several first connecting shafts 306 are fixedly connected to the outer wall of the second fan 305, and several connecting rods 307 are fixedly connected to the outer wall of each first connecting shaft 306. The rotation of the second fan 305 drives the first connecting shafts 306 to rotate, which in turn drives the connecting rods 307 to rotate on both sides of the first positioning plate 101. A gear 308 is rotatably connected to the outer wall of one end of each connecting rod 307 away from the first connecting shaft 306. A rack 309 meshes with the outer wall of the gear 308. Through the meshing of the gear 308 and the rack 309, the gear 308 is pushed by the rack 309 during its movement. This causes the gear 308 to rotate. The outer wall of the rack 309 is fixedly connected to the inner wall of the first positioning plate 101. The outer wall of the gear 308 is fixedly connected to the second connecting shaft 310. The outer wall of the second connecting shaft 310 is rotatably connected to the inner wall of the connecting rod 307. The outer wall of the second connecting shaft 310 away from the gear 308 is fixedly connected to the scraper 311. The rotation of the gear 308 drives the second connecting shaft 310 to rotate, which in turn drives the scraper 311 to rotate. The outer wall of the scraper 311 is slidably connected to the filter plate 312. The outer wall of the filter plate 312 is fixedly connected to the inner wall of the first positioning plate 101. The gas blown out through the second positioning plate 301 and the connecting block 202 is filtered through the filter plate 312.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, the first positioning plate 101 is first inserted into the mounting plate 1. The movement of the first positioning plate 101 causes the four connecting blocks 202 on the outside of the first fan 201 to pass through the mounting plate 1 and simultaneously insert into the limiting block 203 at the other end. The connecting blocks 202 push the pressure plate 205 inside the limiting block 203, simultaneously compressing the spring 204. The elasticity of the spring 204 relieves the pressure. During the movement of the pressure plate 205, the first positioning rod 206 moves, while the limiting rod 207 restricts the movement of the first positioning rod 206. The movement direction causes the limiting rod 207 to push the first positioning rod 206 to rotate. Simultaneously, the front end of the limiting rod 207 inserts into the limiting groove 208 inside the limiting block 203. The first positioning rod 206 pushes the first locking block 209 to move, while simultaneously squeezing the pressure spring 210. The elasticity of the pressure spring 210 pushes the first locking block 209 to lock the limiting rod 207. The same principle applies to the others. At this time, the first positioning plate 101 is fixed inside the mounting plate 1. Then, the first fan 201 and the second fan 305 are activated to blow the gas inside the tongue through the first positioning plate 101. Filtering is performed using filter plate 312. Then, by rotating the second positioning plate 301, multiple second positioning rods 302 can be moved. Since the movement direction of the second positioning rods 302 is restricted by the groove 304 inside the baffle plate 303, but the movement direction of the second positioning rods 302 is fixed, the movement of the second positioning rods 302 within the groove 304 will push the baffle plate 303 to rotate, thereby changing the obstruction area of ​​the multiple baffle plates 303 on the first fan 201 and changing the airflow velocity blown out by the first fan 201. During the rotation of the second fan 305, it will... While the first connecting shaft 306 rotates, it drives multiple connecting rods 307 to rotate on both sides of the filter plate 312. The rotation of the connecting rods 307 drives the gear 308 to move along the inside of the first positioning plate 101. At the same time, the gear 308 meshes with the rack 309. Therefore, during the movement of the gear 308, the rack 309 will push multiple gears 308 to rotate around the connecting rod 307. The gear 308 drives the second connecting shaft 310 to rotate, while driving the scraper 311 to move along the outside of the filter plate 312, thereby scraping away the dust on the surface of the filter plate 312.
