Background: With the improvement of living standards and the acceleration of the pace of modern life, people pay more and more attention to health. All kinds of ball games are deeply loved by people. Most people like to go to all kinds of equipment halls for all kinds of sports. However, at present, there are few types of service machines, and there is still a lot of room for development. With the development of ball games, small simple serve machine, as important equipment for modern entertainment and sports, has research projects in various countries and occupies a large market share. Objective: The purpose of this study is to synthesize the existing pitching mechanism, summarize and analyze the advantages and disadvantages of various pitching mechanisms from a large number of documents and patents, and solve some problems with the existing pitching machine. Methods: This paper summarizes various patents and the latest research progress on ball-pitching machines. From the mechanical structure of the pitching machine to the functions it can realize, the advantages and disadvantages of the serving machine are analyzed. Results: By summarizing the characteristics of a large number of pitching mechanisms, this paper analyzes some problems existing in the pitching machine and looks forward to the research and design of the pitching machine. Conclusion: Combined with relevant mechanical technology, this paper refers to the patents related to various ball automatic mechanical pitching devices and draws valuable conclusions through the summary and comparison of these patents. |
