Development of a manual garden shovel with the ability to quickly clean the working surface

Abstract

Abstract Manual garden shovels have various shapes and sizes, are used to perform a large number of works with soil. A common problem for all garden shovels is the sticking of soil on the working part – the blade. Constant sticking of soil on the blade reduces labor productivity, requires considerable effort and time for cleaning, even the presence of special devices. There are constant attempts to solve the problem of quick cleaning of the blade of manual shovels. Many technical solutions to this problem are patented and are actively used in practice. The design of the self-cleaning shovel consists of a handle and a metal blade with a sharpened cutting edge fixed at one end of the handle, a tubular clamp and footrests, as well as a cleaning plate that is fixed to the movable handle, and a compression spring located under the movable handle around the tubular clamp of the shovel. Cleaning of a metal blade is performed by the cleaning plate, which moves along the metal blade from the footrests to the cutting edge and back. To do this, the user moves the movable handle towards the metal blade, providing compression of the spring.
