MACHINE FOR DIGGING OUT ROOTS AND RHIZONES OF LICORICE OF LICORICE IN NATURAL OVERGROWTH AND PLANTATIONS(GLYCYRRHIZA CLABRAL AND GLABRAL AND GLYCYRRHIZA URALENSIS FISCH)

摘要

FIELD: agricultural engineering and forestry. ^ SUBSTANCE: invention relates to machines for picking drug plants from considerable depth. Proposed machine has frame, working member for digging up and cutting out layers and separating device in form of two driven beaters installed in tandem. In working member for digging up and cutting out of layers, places where undercutter connects with sides are provided with inclined plates. Front parts of sides have cutting edges on two-edge blades changing into cutting edges of one-side blades of undercutter plates. Rear part of undercutter is provided with curvilinear chute. First beater length wise the frame is provided with flexible members arranged at equal angular pitch on peripheral part of disks installed at edges ob beater hub. Each flexible member is made ion form of length of multicore wire rope of anchor chain links. Links of chain or lengths of wire rope are installed to arc described by equations S=2a.SH(x:a); where S is length of arc of flexible member, a is parameter, SH is hyperbolic sine and x is abscissa counted from middle of beater symmetry axis and y is ordinate of point to be found. Ends of said flexible members are connected by hinge joints and adapters with disks of beater hub. Second beater has pair of freely rotating rollers installed in its diametrical plane. ^ EFFECT: increased capacity, reduced cost of drug raw materials.
