摘要
为明晰农田土壤捡石机械化技术发展现状,通过PatSnap(智慧芽)专利检索平台,采用专利计量方法对农田土壤捡石机械化技术在1990年1月1日—2022年10月24日期间全球申请专利的整体情况、申请趋势、申请地域情况、申请人情况以及相关典型机型进行分析,并用可视化的方法展示该技术领域的创新状况。结果表明:全球农田土壤捡石机械化技术经历从孕育时期、初步发展时期、调整时期到现如今的快速发展时期,全球共申请捡石机械化技术领域相关专利583件,其中中国申请捡石机械化技术领域相关专利149项,约占全世界25.6%。中国相关专利申请主要集中在安徽省、山东省、江苏省,其中,企业申请数量占比69.8%,科研院所和高校申请占比14.8%。总结分析全球农田土壤捡石机械按结构原理分为轮齿式、铲链式、铲刀转笼式和齿耙式;并介绍目前应用较好的代表机型及结构特点。指出我国捡石机械技术目前仍存在捡石机捡石机理研究薄弱、捡石机的稳定性和可靠性较差以及捡石机经济效益低,不易推广等问题。结合我国国情提出我国捡石机械需要加快开展捡石机的基础理论研究、提高机具适应性以及可靠性、技术多元化与装备智能化。
In order to clarify the development status of mechanized technology for picking up stones in farmland soil,through the PatSnap patent retrieval platform,the patent measurement method was used to analyze the overall situation,application trend,application area,applicant situation and related typical models of the global patent application of mechanized technology for picking up stones in farmland soil during the period from January 1,1990 to October 24,2022,and the innovation status of this technology field was displayed by visual method.The results show that the mechanization technology of soil stone picking in the global farmland has experienced from the gestation period,the initial development period,the adjustment period to the rapid development period.A total of 583 patents in the field of stone picking mechanization technology have been applied globally,of which 149 patents in the field of stone picking mechanization technology have been applied by China,accounting for about 25.6% of the world.The relevant patent applications in China are mainly concentrated in Anhui,Shandong and Jiangsu Provinces.Among them,the number of patent applications applied by enterprises accounts for 69.8%,and the number of patent applications applied by scientific research institutes and universities accounts for 14.8%.According to the structural principle,the global farmland soil stone picking machinery can be divided into gear type,shovel chain type,shovel cage type and tooth rake type.The representative models and their structural characteristics are also introduced.It is pointed out that there are still some problems in our country,such as weak research on the mechanism of stone picking machine,poor stability and reliability of stone picking machine,low economic benefit of stone picking machine and difficult to popularize.According to the national conditions of our country,it is suggested that China's stone picking machinery needs to accelerate the basic theoretical research of stone picking machine,improve the adaptability and reliability of the machine,as well as the diversification of technology and intelligent equipment.
