Description

Technical Field

[0001] The utility model relates to a disinfection spray device, specifically a disinfection spray device for livestock and poultry houses in veterinary medicine, belonging to the technical field of livestock and poultry house disinfection. Background Technique

[0002] A livestock and poultry house is a building and facility that provides a breeding and growing environment for livestock and poultry. It provides necessary feeding conditions for livestock and poultry, such as shelter, heat preservation, ventilation, lighting, and safety management, etc.

[0003] Disinfection of livestock and poultry houses is one of the important measures in the livestock production process. It mainly uses the method of spraying disinfectants with a spray device to effectively kill and remove pathogens in the livestock and poultry houses, such as bacteria, viruses, fungi, and parasites, etc., thereby reducing the occurrence and spread of diseases, effectively controlling the outbreak of epidemics, improving production efficiency, and ensuring product quality.

[0004] Traditional disinfection spray devices for livestock and poultry houses usually need to be carried on the back manually. This not only increases the labor cost and has low disinfection efficiency, but also there is a safety risk of inhalation for the staff when spraying disinfectants.

[0005] Chinese Patent Publication No.: CN217093997U discloses a disinfection spray device for livestock and poultry houses in veterinary medicine. This utility model can remotely control the device through a controller to make the whole device move, without manual spraying of disinfectant solution, greatly reducing the labor intensity of the staff, and avoiding workers inhaling the disinfectant aerosol, ensuring the physical health of the workers. By controlling the double-axis motor, the atomizing nozzle can swing, so as to evenly spray and disinfect the livestock and poultry house, effectively expanding the disinfection range, and has practicability.

[0006] However, although this device does not require manual spraying of disinfectant solution and ensures the physical health of the workers, the spraying direction of its disinfectant solution is horizontal. Although the atomizing nozzle can swing, the distribution of the sprayed disinfectant solution is not uniform, and it is easy to appear the phenomenon of disinfection dead corners, affecting the disinfection effect. Moreover, its water tank and the whole device are of an integrated structure, resulting in that the whole device needs to have a high load performance, affecting the use cost of the device. For this reason, a disinfection spray device for livestock and poultry houses in veterinary medicine is proposed. Summary of the Utility Model

[0058] In one embodiment, the tube bundle mechanism 5 includes a plurality of pulleys 501, a plurality of sliders 502, and a plurality of springs 503;

[0059] Among them, a plurality of pulleys 501 are all slidably connected to the inside of the inner bracket 102, the protective sleeve 403 is wound around the plurality of pulleys 501, a plurality of sliders 502 are respectively rotatably connected to both ends of the plurality of pulleys 501 through bearings, the outer side walls of the plurality of sliders 502 are all slidably connected to the inner side wall of the inner bracket 102, and a plurality of springs 503 are respectively fixedly connected between the plurality of sliders 502 and the inner side wall of the inner bracket 102; The moving protective sleeve 403 drives the pulleys 501 to move, the moving pulleys 501 drive the sliders 502 to slide inside the inner bracket 102, and drive the springs 503 to be compressed.

[0060] In one embodiment, a plurality of mounting ears 62 are fixedly connected to the outer side wall of the outer frame 101; The outer frame 101 is installed by using the mounting ears 62.

[0061] In one embodiment, in the Y-axis direction: it is the direction of the Y-axis threaded rod 304; In the X-axis direction: it is the direction of the X-axis threaded rod 202

[0062] When the utility model works: The outer frame 101 is integrally installed and fixed on the indoor top of the livestock house by using the mounting ears 62, and then the liquid extraction pipe 406 is communicated with the container for containing the disinfectant.

[0063] When the livestock house is cleaned and emptied and disinfection is required, the disinfectant solution is prepared using a container. Then, the pressure pump 401 uses the liquid suction pipe 406 to extract the disinfectant solution from the container, and the supply pipe 402 is used to inject the disinfectant solution into the inside of the spray rack 404. Then, under the action of pressure, the atomizing nozzle 405 atomizes and sprays the disinfectant solution from the spray rack 404.

[0064] The output shaft of the second motor 301 drives the Y-axis threaded rod 304 to rotate through the bevel gear 305. The rotating Y-axis threaded rod 304 drives the internal threaded block 306 to move using the thread. The moving internal threaded block 306 drives the spray rack 404 and the atomizing nozzle 405 to move along the Y-axis direction. The guiding rod 63 is provided to guide the moving internal threaded block 306, ensuring the stability of the internal threaded block 306 during movement. When the internal threaded block 306 moves to the limit, one action of the second motor 301 is completed.

[0065] After one action of the second motor 301 is completed, the output shaft of the first motor 201 drives the X-axis threaded rod 202 to rotate, and then a second action is performed. The rotating X-axis threaded rod 202 drives the traction frame 103 to move using the thread. The moving traction frame 103 drives the support frame 303 to slide in the guide groove 61, so as to drive the overall Y-axis drive mechanism 3 and the spray structure to move along the X-axis direction. At the same time, the moving traction frame 103 drives the protective sleeve 403 to move. The moving protective sleeve 403 drives the supply pipe 402 and the pulley 501 to move, so as to ensure that the supply pipe 402 can supply water to the inside of the spray rack 404 normally. The moving pulley 501 drives the slider 502 to slide inside the inner support 102 and drives the spring 503 to be compressed, so as to reduce the distance between the pulleys 501, enabling the protective sleeve 403 to have enough length to be pulled out.

[0066] After the second action of the first motor 201 is completed, the output shaft of the second motor 301 drives the Y-axis threaded rod 304 to rotate in the reverse direction through the bevel gear 305, so that the internal threaded block 306 that has moved to the limit on the Y-axis threaded rod 304 moves in the reverse direction, and then a third action is performed. Thus, by repeating the actions of one, two, and three, the disinfectant solution can be evenly sprayed from top to bottom into the livestock house to complete the disinfection operation.

[0067] When the traction frame 103 moves to the limit, the disinfection work is completed. The extraction of the disinfectant solution is stopped by turning off the pressure pump 401, and the output shaft of the first motor 201 is used to drive the X-axis threaded rod 202 to move in the reverse direction, so as to reset the entire traction frame 103. At the same time, the compressed spring 503 uses the slider 502 to drive the pulley 501 to reset, so as to use the reset pulley 501 to retract the pulled-out protective sleeve 403 and restrain it inside the inner support 102.

[0068] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the said claims.
