Technical Field

[0001] This utility model belongs to the field of dairy cow medication technology, specifically relating to a dairy cow medication spraying device. Background Technology

[0002] In modern dairy farming, the health of dairy cows is directly related to the yield and quality of milk. Common skin diseases and parasite infections in dairy cows require regular drug treatment. Spraying medication on dairy cows is for purposes such as deworming and disease prevention, mosquito and fly control, and environmental disinfection. The spraying is mainly concentrated on the surface of the dairy cow's body, such as the spine, neck, waist, and buttocks, which are easy to cover.

[0003] Most existing dairy cow medication spraying equipment uses handheld spray guns or fixed nozzles. During operation, it is necessary to manually hold the equipment and spray each cow individually, which is not only time-consuming and labor-intensive, but also cannot guarantee that the cow's skin surface is evenly sprayed with medication. In addition, because dairy cows are large, personnel need to move frequently during the spraying process, which not only increases the workload, but also poses safety hazards. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a dairy cow medication spraying device that solves the problems of time-consuming and laborious manual handheld spraying of medication on each cow, the inability to ensure uniform medication coverage on the cow's skin, and the need for frequent movement of personnel during the spraying process due to the large size of dairy cows, which increases the workload.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dairy cow medication spraying device, comprising a protective fence one and a protective fence two, wherein the protective fence one and the protective fence two are arranged opposite to each other. A movable component is provided on the side of the protective fence two facing the protective fence one, and a guide component is provided on the side of the protective fence one facing the protective fence two at the same horizontal line as the movable component. The movable component and the guide component are respectively connected to movable block one and movable block two on opposite sides, and a positioning ring is fixedly provided on the opposite side of both movable block one and movable block two. The positioning ring is sleeved on the outside of the connecting pipe one and fixedly connected thereto. Several equidistant rings are fixedly provided on opposite sides of both sets of connecting pipe one. The nozzle is one, and the top end of the connecting pipe is through both ends of the mounting base and fixedly connected thereto. The mounting base is provided with an adjustment component, which includes a slide rod that passes through the top end of the sliding connecting pipe. Each gear has a connecting plate fixedly attached to its top end, and a rack is fixedly attached below each connecting plate. The rack meshes with the gear, and the gear is rotatably mounted at both ends of the mounting base. The two sets of gears are connected to a worm gear through a transmission component, and the worm gear is located at the center of the mounting base.
