METHOD AND AGRICULTURAL MACHINE FOR SOIL TILLAGE Russian patent published in 2005 - IPC

FIELD: agriculture.

SUBSTANCE: method involves tilling soil by working tools; providing additional soil tillage after plowing operation by disintegrating crumbs for moisture retention and producing of biomass with the help of agricultural machine wheels mounted behind working tools; adjusting plow depth and engine loading during tillage operation; tilling soil by disks, rhombic tools, teeth, skim colters, plows, tools arranged behind plows, and wings; during soil tillage, reducing compaction extent, pitch and angle of arrangement of working tools; moving wheels to working tool operating mode and/or moving working tools to supporting mode. Working tools may be made formed as self-rotating acute-angled reversing teeth. Machine engine power is distributed between wheels and working tools for providing change-over and alternating operation, changing the number and connection circuit of power consumers for adjustment of velocity. Machine may rotate at zero radius through motive force of one wheel. During tillage, furrow is formed for further utilization as terrace, path, channel on irrigation field, basic line for movement, with stones and process soil shear being used for construction thereof. Soil surface state is changed by adjusting advancement velocity. Reduction of said velocity is used for increasing tillage depth, and increase of said velocity is used for withdrawal of working tools and formation of furrows, channels, terrace or paths. Machine has engine for driving of running part and working tools, and hydraulic machine. Mechanical levers are mounted on drive wheel shaft and equipped with pivot joints for sections provided with wheels, working tools and retainers for retaining of adjusted movement and position of working tools and wheels. Hydraulic machine has rotor, stator with feeding lines, deepeners for pumps adapted for closing of working cavities to provide symmetric loading of rotor at both sides upon rotation and hydraulic pressing of surfaces without formation of dead areas. Drive wheel and section wheels are equipped with hydraulic motors adapted to be actuated, deactivated, connected in series or in parallel for adjustment of advancement velocity. Machine has turning plow having wings on its working surface or on reverse side or disk mounted on crank for right-hand or left-hand repositioning, working tools-wheel substitutes and wheels-working tool substitutes. Engine and wheels are made from aviation waste.

EFFECT: increased mechanization extent, reduced power consumption and resource saving.
