摘要：
Utility model "arcuate support cutting spades," relates the International Patent Classification Class A "Human necessities".The device is intended to facilitate horticultural and other digging work shoveling, lifting part of the processed material (earth, soil, soil, mortar, sand and cement) above the level of the under support bulk and discharge it to the side, and without departing support from the surface level the bulk material.The arcuate bearing cuttings shovels - a half-arches (semicircle, semi-oval, semi-ellipse) having a lug, e.g., circular or ring crimped, at its ends, through which the threaded shank shovels. One eyelet support is located directly at the top of the blade shovel, another in the region bearing diameters - also on the handle, the convex part of the support arch rests on the surface of the treated material (soil, earth, soil, turf), which may be a thrust bearing to prevent drowning arc base in loose or bulk material by reference.Convexity support allows swinging movement of the cutting blade and the shovel down-up, perform a rotation about pivot point above the surface of the processed material without raising the bulk of the support surface, rotation of shovel blade lugs in a fixed upright support.Arc eyes are not fixed rigidly to the handle of a shovel, suspension sags freely under its own weight in the upright position.Handle shovels and the arc lever of the first kind is formed with a short arm (of a shovel blade to the point on the arc foot pasture material) and length (from the point of the arc foot to the opposite end of the cutting blade shovels). Fulcrum is projected on a cutting shovel.Point touch support arc soil shifts depending on the inclination of the cutting shovel. At high partite position of the cutting blade end (e.g., when entering the blades ground) of the arc foot point close to the blade during horizontal cutting position - is removed from the blade support to half the diameter of arc.This causes changes in the lengths
