Technical Field
[0001] The utility model relates to the technical field of stirring equipment, in particular to a uniform feeding device for a pellet spraying machine. Background Art
[0002] At present, the material supply of pellet sprayers mainly uses forklifts, shovels and other scraping equipment to transport materials to the sprayer feed port, and then manually split and load them. This is not only time-consuming, but also there is a risk of operators falling into the mixing chamber during the loading process. In addition, since different materials have different dispersion processes in water, adding them to the sprayer mixing chamber in sequence for mixing takes a long time, which reduces the efficiency of the sprayer and the cost is high. Therefore, the utility model designs a uniform feeding device to mix all kinds of materials in advance, reduce the risk of operators, reduce costs and increase efficiency. Utility Model Content

[0016] The following is a clear and complete description of the technical solutions of this utility model in conjunction with the following embodiments. Obviously, the embodiments described here are only a portion of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are also within the scope of protection of this utility model.
[0017] like Figure 1-3 As shown, a uniform feeding device for a pellet sprayer includes a sprayer 1, a feeding device 2, a scraper conveyor body 3, a spiral ribbon stirring blade 4, a stirring shaft 5, a stirring chamber discharge port 6, a hydraulic motor 7, a support frame 8, a scraper conveyor discharge port 9, and a stirring chamber shell 10. The hydraulic motor 7 is connected to the stirring shaft 5, and the stirring shaft 5 is connected to the spiral ribbon stirring blade 4. The spiral ribbon stirring blade 4 is installed inside the stirring chamber shell 10. The stirring chamber discharge port 6 is located at the bottom of the stirring chamber shell 10. The support frame 8 is connected to the stirring chamber shell 10. The scraper conveyor body 3 is installed below the stirring chamber discharge port 6, and the scraper conveyor discharge port 9 is installed at the highest point of the scraper conveyor body 3.
