ПОЧВООБРАБАТЫВАЮЩЕЕ ОРУДИЕ ДЛЯ БЕЗОТВАЛЬНОЙ ОБРАБОТКИ ПОЧВЫ

摘要

FIELD: agricultural engineering. ^ SUBSTANCE: tillage tool has actuating devices and drive adapted for driving of actuating devices and made in the form of connecting rod-crank mechanism connected to tractor's takeoff shaft. Radius of crank (rc) is half the predetermined tillage depth (h). Length of rocker (lr) is determined by dependence lr=4rc. Length of connecting rod (lcr) is determined by formula lcr=2rc. Height of working tool is equal to tillage depth (h). Number of working members is even and is within the range of 4-10. Working members are mounted on crank shaft in angularly offset relation, with offset being equal to alphay=(360 deg:n)2. During operation, crank performs complicated motion along path with coordinates of points described by equations in axes: xi=rc(alphai/lambda+sinalphai), yi=rc(1-cosalphai). Absolute speed of crank is determined by formula: Va=Vc(1+1/lambda2+cosalphai)0.5. Acceleration of any point of crank is alpha=rcomegac 2. ^ EFFECT: reduced consumption of power and increased quality of basic soil tillage on slopes and on soils exposed to water erosion. ^ 2 cl, 3 dwg
