APPARATUS FOR SUBSOIL APPLICATION OF LIQUID FERTILIZERS Russian patent published in 2004 - IPC

Abstract RU 2228587 C2

FIELD: agricultural engineering. SUBSTANCE: apparatus has injection needles and device made in the form of falling hammer and adapted for deepening of injectors into soil. Hammer is made in the form of holder including striking hammers movably connected with one another and adapted for engagement with respective needles. Each needle is deepened into soil under the action of respective hammer. Such construction prevents holder from bending in case needle gets onto hard object. EFFECT: enhanced reliability in operation and reduced material usage. 2 cl, 5 dwg
