CULTIVATOR MULTIPLE-UNIT TOOL Russian patent published in 1995 - IPC

FIELD: soil loosening. SUBSTANCE: the construction, having a post, duck-foot shovel, liquid intake conduit and one sprayer located behind the post, below the upper edge of the duck-foot shovel shares allows preparations to be applied into soil both in usual rates (above 80 l/ha) and small rates (less than 50 l/ha) without worsening the quality indices of liquid distribution under the soil layer. Stable quality of liquid distribution in operating width is attained by special direction of the sprayer in the undershovel space. The construction provides for direction of the end member of the sprayer flow - through part with the outlet towards the cutting plane section enclosed between the cutting edges of the duck-foot shovel. The axis of the end member of the sprayer flow-through part intersects the said section of the cutting plane and the lower surface of the shovel arched-head part. The latter is intersected by the axis above the level of the locus of the center of gravity of the sprayer outlet. If the construction uses a deflector sprayer, the latter should be installed in such a manner that the tangent lines to the deflector working surfaces are directed not in parallel with the plane passing through the two cutting edges of the duck-foot shovel and intersect it in continuation. Such an installation of the sprayer prevents intersection of the spray cone by falling soil particles at its direction right towards the bottom of the furrow being formed by the duck-foot shovel. EFFECT: facilitated procedure. 6 dwg
