DEEP-TILLAGE CHISEL TOOL Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, soil mellowing and slitting equipment.

SUBSTANCE: deep-tillage chisel tool has tine composed of two rigidly connected parts: upper part having parabolic front face and equipped with hoe, and lower part declined rearward and equipped with chisel arranged in its lower portion. Tine is inclined rearward. Chisel blade is arranged along longitudinal axis of deep-tillage chisel at distance L from hoe edge. Width B of hoe is greater than width b of chisel. According to formula L ≥ 1.2H, where H is soil tillage depth, soil jamming between hoe and chisel is eliminated, because splitting of soil is provided into space arranged behind hoe and free of soil. Ratio B ≥ b + 1.7H restricts hoe width so as to provide for space free of soil and equal to width of strip of soil surface deformed by chisel.

EFFECT: increased mellowing zone owing to predetermined ratio of parameters of deep-tillage chisel tool and reduced power consumption.
