FIELD: agricultural engineering. ^ SUBSTANCE: stone picking machine has frame, pile forming sections of chain conveyor, straight teeth positioned in two parallel rows along lateral sides of isosceles triangles, with teeth of innermost rows being positioned with greater space than teeth of outermost rows, picking chain conveyor on which crescent teeth are positioned in transverse rows on rolls, with innermost row teeth being positioned with greater space than outermost row teeth. Frame has trapezium-shaped portion with lateral rectangular frame parts having horizontal base. Picking chain conveyor is located on trapezium-shaped portion. Pile forming sections of chain conveyor are positioned on rectangular frame parts. ^ EFFECT: reduced material usage and increased efficiency by improved maneuverability. ^ 3 dwg |
