Machine for gathering plant roots Machine for gathering plant roots has a frame, tow bar, front axis with a wheel, rear axis with wheels, load platform with lateral and rear boards, hydraulic actuator for the load platform, mounted on the front part of the frame and equipped with actuators for rotation and lifting and a rotor with tow hooks and an inclined conveyer fitted one after the other. The inclined conveyer in form of infinite branches of bush-roller chains and planks is sectional. Each section is fitted between tow hooks of the main, intermediate and secondary rotors. Each section of the inclined conveyer is mounted through pairs of sprockets, fitted between tow hooks of the main and secondary rotors. The sprockets are fixed, for example, by tapered keys on rotor hubs. The diameter of the tow hooks is 2-3 times bigger than the diameter of the pitch circle of the inclined conveyer. The frequency of rotation of the intermediate rotor, fitted between the main and secondary rotors, is more than the frequency of rotation of the main rotor by 3-4 times. The sectional inclined conveyer with rotors is mounted on an auxiliary frame and is mounted on the frame of the machine through hinge joints and hydraulic actuator lifting. Fitted with provision for rotation about the horizontal axis, perpendicular to the direction of motion of the machine, the load platform is made in form of diametrical buckets, fitted on the same hollow axle-journal. One of the buckets is in the loading mode, while the other is in the evacuation mode. On one journal potion of the axle-journal, a star wheel is mounted with limited angular displacement, as well as a hinged arm with a releasing cam, swinging on the journal, intermeshed with the star wheel. The other end of the swinging arm is joined by pin to the rod of the hydraulic actuator of the load platform. |

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. |

Licorice root extracting machine Licorice root extracting machine has frame, supporting-following wheels, and successively arranged device for digging, lifting, moving and primary separation of root soil layer. Said device is made as U-shaped undercutting knife whose front parts are provided with cutting edges on detachable blades. Apparatus is further provided with device for secondary separation of soil layer. Said device is formed as drive disk obliquely positioned with respect to axis of rotation and having diameter smaller than width of soil layer digging device. |

Licorice root harvesting machine Machine has frame incorporating undercutting device, extracting device and related drive, with mentioned parts of machine being successively mounted on frame. Separator for separating root soil layer is positioned between undercutting device and extracting device. Separator is made in the form of drive crankshaft, whose necks are connected through flexible binders with undercutting device. |

Method involves compacting soil and imparting rough surface thereto during licorice postharvest period; cutting into agronomically valuable fractions of large lumps and soil aggregates while continuously advancing on strip surface and on slopes in the vicinity of ditch; moving soil therefrom into mid portion of ditch during strip soil compaction and forming groove-type drain with water-distributing slot along its axis; during extraction of licorice raw material, grinding 3-7% of root mass into 10-25 cm long pieces with one-five dormant auxiliary buds and leaving in mid portion of layer of strip to be harvested. Machine for extraction of licorice roots has frame, carrier wheels and undercutting device mounted on H-shaped bar and coupled to frame for automatic displacement into transport position. Drive members are disposed in longitudinal beams of H-shaped bar, which is additionally fixed on frame through variable length tie-rods. Machine is further equipped with toothed rotor driven from tractor. At least one of teeth located on mid portion of rotor is provided with replaceable knife, which is arranged on peripheral part of tooth, is made of inversion type and is provided with blade. Ratio of blade and rotor lengths is within the range of (0.03-0.07):1. Knife is mounted at tooth end by means of shaft and cut-off pin. |

Method involves preliminarily plowing root layer by deep cutting of soil layer without turning and deformation thereof by means of, preferably, flat U-shaped working tool; separating soil and separating rootstocks and roots during second passage along track of previous working tool by lifting undercut layer with the help of inclined lifters and by providing periodic impacts upon lifted layer from the bottom to the top by means of teeth of rotating rotor, with following moving of licorice roots and rootstocks onto surface of tilled soil strip and of soil aggregates and ground to the initial position; providing soil strip of 1.9-2.2 m width by rotavating soil top layer to 0.03-0.06 m depth; cutting 1.1-1.3 m wide and 0.45-0.65 m deep soil layer at one edge of tilled strip; during lifting of undercut layer and deformation thereof, separating root layer into small-sized and large-sized soil aggregates and root mass; laying extracted and separated roots and rootstocks onto remaining part of tilled strip; simultaneously covering surface of undercut layer having soil aggregates moved to the initial position. Machine has frame, separator with inclined lifters, and rotor positioned behind inclined lifters and equipped with drive having teeth with framed working edges. Machine is further provided with vibrating screen mounted behind rotor, and tray for laying licorice roots and rootstocks at the side of frame. Each lifter is mounted on transverse beam of frame and is equipped with chisel positioned on its lower part. Front face of lifter is made flat, with different angles of inclination with respect to horizontal plane. |
