Development of an innovative agricultural tool for farmers who use manual labor in crop production

The article substantiates the relevance of the development of an innovative agricultural tool for farmers - manual self-cleaning rake. The device is related to agriculture, to manual tools with teeth in particular, and can be used for soil treatment and harvesting cultivated plants. Constant clogging of the rake's teeth reduces the productivity of those who use them. The teeth cleaning requires a significant amount of time and effort, and special additional devices. Known scientific and technical solutions do not allow to reduce to a minimum the user's movements when cleaning the teeth, do not provide a balanced cleaning of the teeth, especially when they are heavily clogged. The proposed device contains a cleaning plate that is formed with many spaced holes passing through the teeth. Moving this plate along the teeth of rakes or similar devices ensures their quick and balanced cleaning. The article describes the features and disadvantages of patented scientific and technical solutions, as well as the design features of the proposed innovative agricultural tool.
