Description
Technical Field
[0001] This utility model belongs to the field of cattle breeding technology, specifically relating to a cooling and dust prevention device for bull sheds. Background Technology
[0002] High summer temperatures can cause heat stress in cattle sheds, leading to reduced feed intake and weakened immunity. Commonly used ventilation and cooling systems typically rely solely on fans, which can easily bring in outdoor dust and debris. In addition to ventilation, air filtration is also necessary. Accumulated dust on the dust filters can clog them, requiring regular cleaning. Manual cleaning is time-consuming, labor-intensive, and inefficient. Furthermore, the dust swept away during manual cleaning can be re-adsorbed onto the filters or re-enter the shed due to wind pressure, negatively impacting air quality. Summary of the Invention
[0003] To overcome the problems of time-consuming, labor-intensive, and inefficient manual cleaning of dust screens in the prior art, and the fact that dust swept off during manual cleaning can be re-adsorbed onto the dust screen or enter the cattle shed due to wind pressure, affecting the air quality inside the cattle shed, this utility model provides a cooling and dust prevention device for bull sheds. When cleaning is required, the equipment can be started to complete the cleaning work. The dust screen 6 is moved by the wire mesh conveyor belt 41 installed on the air inlet duct 1. The dust on the dust screen 6 is cleaned by the high-pressure air jet device 7. The dust collected by the negative pressure dust collection device 8 is collected in time to prevent it from being sucked back into the dust screen or the cattle shed. The dust screen can be cleaned without stopping the fan 3, which effectively improves the cleaning efficiency and reduces the intensity of manual labor.

The front end of the air supply pipe 2 is connected to the end of the air inlet duct 1. The fan 3 is installed inside the front end of the air supply pipe 2. Branch pipes are provided at the end of the air supply pipe 2, with the ends of the branch pipes evenly distributed on the top of the shed. Through holes 11 are provided on both sides of the outer end of the air inlet duct 1. The wire mesh conveyor 4 is installed on the outside of the side wall of the shed via the frame 5. The wire mesh conveyor belt 41 of the wire mesh conveyor 4 passes through the through holes 11 and is laterally intercepted at the end of the air inlet duct 1. The dustproof net 6 is installed... The equipment is mounted on the wire mesh conveyor belt 41. Both the high-pressure air jet device 7 and the negative pressure dust collection device 8 are installed on the outside of the cowshed side wall. The nozzle 71 of the high-pressure air jet device 7 is located inside the wire mesh conveyor belt 41, while the suction port 81 of the negative pressure dust collection device 8 is located opposite the nozzle 71 on the outside of the wire mesh conveyor belt 41. When cleaning is required, the equipment is started to complete the cleaning work. The wire mesh conveyor belt 41 installed on the air inlet duct 1 drives the dustproof net 6 to move. The high-pressure air jet device 7 cleans the dust on the dustproof net 6, and the negative pressure dust collection device 8 collects the cleaned dust in a timely manner, preventing it from being sucked back into the dustproof net or the cowshed. The dustproof net can be cleaned without stopping the fan 3, effectively improving cleaning efficiency and reducing manual labor intensity.
[0019] The wire mesh conveying device 4 includes a wire mesh conveyor belt 41, a chain 42, a sprocket 43, a rotating shaft 44, and a motor 45. The wire mesh conveyor belt 41 is equipped with chains 42 on both sides. Two rotating shafts 44 are installed parallel to each other on the frame 5. The sprocket 43 is fixedly installed on the rotating shaft 44. The wire mesh conveyor belt 41 is driven to the rotating shaft 44 by the chain 42 and the sprocket 43. The motor 45 is installed on the frame 5 and is connected to one of the rotating shafts 44. The motor 45 drives the rotating shaft 44 and the sprocket 43 to rotate, thereby driving the wire mesh conveyor belt 41 and the chain 42 to rotate. The dustproof net 6 installed on the wire mesh conveyor belt 41 moves with it, removing the dust-covered section of the dustproof net inside the air inlet duct 1. The high-pressure air jet device 7 and the negative pressure dust suction device 8 on both sides of the net clean the dust.
[0020] The high-pressure air jetting device 7 includes a nozzle 71, an air supply pipe 72, and an air compressor pump 73. The air supply pipe 72 is installed on the frame 5. The nozzles 71 are evenly installed on the side of the air supply pipe 72 near the wire mesh conveyor belt 41. The air supply pipe 72 is connected to the air compressor pump 73.
[0021] The negative pressure dust collection device 8 includes a dust collection hood 82, a fan 83, and a dust collection bag. The dust collection hood 82 is mounted on the frame 5. The dust collection port 81 of the dust collection hood 82 and the blow nozzle 71 are located opposite each other on both sides of the wire mesh conveyor belt 41. The dust collection hood 82 is connected to the fan 83. The dust collection bag is installed on the air outlet of the fan 83 by a clamp. The high-pressure air blown out by the blow nozzle 71 blows the dust off the dustproof net 6, and then the dust is collected into the dust collection bag by the dust collection hood 82 of the negative pressure dust collection device 8. The dust in the dust collection bag can be cleaned periodically.
[0022] The air inlet duct 1 has two through holes 11 on both sides of its outer end. The two layers of the annular wire mesh conveyor belt 41 pass through the two through holes 11 respectively. According to the rotation direction of the wire mesh conveyor belt 41, the positions where the wire mesh conveyor belt 41 moves out of the through holes 11 are equipped with corresponding dust suction ports 81 and blow nozzles 71.
[0023] The air inlet duct 1 is provided with sliding grooves 12 on both the upper and lower sides, corresponding to the through holes 11, to limit the edge of the wire mesh conveyor belt 41. The edge of the wire mesh conveyor belt 41 and the edge of the dustproof net 6 are slidably embedded in the sliding grooves 12, reducing the gap between the edge of the dustproof net 6 and the inner wall of the air inlet duct 1, and improving the dustproof effect.
[0024] Work process:
[0025] When cleaning is required, the equipment is started to complete the cleaning work. The motor 45 drives the rotating shaft 44 and sprocket 43 to rotate, which in turn drives the wire mesh conveyor belt 41 and chain 42 to rotate. The dustproof net 6 installed on the wire mesh conveyor belt 41 moves along with it, removing the dust-covered dustproof net section in the air inlet duct 1. The high-pressure air jet device 7 and negative pressure dust collection device 8 on both sides clean the dust. The dust collected by the negative pressure dust collection device 8 is collected in time to prevent it from being sucked back into the dustproof net or the cowshed. The high-pressure air blown out by the nozzle 71 blows the dust off the dustproof net 6, and then the dust is collected into the dust collection bag by the dust collection hood 82 of the negative pressure dust collection device 8. The dust in the dust collection bag needs to be cleaned regularly. The dustproof net can be cleaned without stopping the fan 3, which effectively improves the cleaning efficiency and reduces the intensity of manual labor.
