Useful model relates down the agriculture, namely to the manual implements of labor for the orchard and vegetable garden works. Task of useful model - improvement of the construction of adaptation for the digging up of the earth, the decrease of the physical expenditures with working of soil, the minimization of the working class movements and efforts (improvement in ergonomics). Technical result consists before the decrease of the efforts of sinking blade beside ground, soil, t [k] decreases the resistance to motion of blade based on the side of ground because of the fulfillment of the cutting edge of 6 metallic sheets 5 (fabric of operating unit) with the radius of bending 120 mm and fulfillment of the rise-and-fall central rod. Before the adaptation for the digging up of the earth, that contains the central rod, which consists of two parts of 3 and 4, with pointed tip 8 before the lower part, transverse lever 1 with the knobs and blade, executed of in the form convex metallic sheet, metallic sheet is bend out along a radius of 200-300 mm, cutting edge is executed with the radius of bending 120 mm, in this case the cutting edge is sharpened on the preset angle of the order of 3-8° down the width of 8-10 mm. thus, the fulfillment of the blade of the fabric of operating unit with the continuous cutting edge, executed along the radius of bending 120 mm, and the fulfillment of the pe[guliruemogo] on the height central rod they decrease the efforts of sinking blade beside ground and, as a result, decrease the physical expenditures with the work, which leads down the improvement ergonomics. But the bending of fabric along a radius of 200-300 mm improves the retention of soil on the fabric with its revolution, which increases productivity of labor and quality of digging. 7 [z].[p]. of formula, 5 illus. |
