MANUAL DEVELOPMENT OF THE SURFACE LAYER OF THE SOIL OF HOUSEHOLD PLOTS WITH ERGONOMIC SHOVELS

The selection of soil development is generally guided by the need to treat a certain area site in shortest time and with least effort energy. In small household plots, grant carried out hand garden shovels without use mechanized or electromechanized means. Such blades have sharp metal extended tip wooden shaft. They are widely used due their relative cheapness, but they low productivity because width 0,20...0,24 m. It should be noted that when digging shovels, it necessary raise removed main load on hands. Therefore, advisability using an ergonomic shovel during manual upper layers backyard park areas proposed where not advisable electro-mechanized invention relates structure parameters shovel, sequence cycle from illustration its stages, energy characteristics trajectory ground «body», which separated array per cycle. purpose article justify efficiency design ergonomic, principle economic features. Conclusions. feasibility effectiveness limited amount topsoil substantiated. muscle strength workers illustrated only rearranged levers rotated while digging. There no lifting direct overturning soil. woker’s up 20…30 m2 hour, 2−3 times more than usual less labor.
