The root crops harvesting machine comprises a main frame, the rack with a lift device fixed on it, root-taking discs, two beaters and a screw cleaner. The cleaner is designed as two successively mounted sets, each of which consists of two screws, a roll and a support bracket. Over the second screw of the front set a spring-loaded guide in the form of a gear wall is mounted.

Invention relates to a group of agriculture. Method of harvesting beet tops with its ensilage involves cutting the tops with the top of the root, cleaning piles of the tops from impurities of soil, and loading the tops to the technological vehicle constantly moving between rows of sugar beet with uncut tops on the unharvested side next to the top harvester. After loading the tops are transported to a place of ensilage, followed by unloading by placing in a surface clamp by the layer on top of previously laid layers, with the tops are placed on the previous layer in the surface clamp by throwing it from the tailgate of a technological vehicle body, made in the form of carrier-thrower. The technological vehicle for harvesting beet tops contains a wheeled chassis, body with sideboards hingedly connected to the chassis frame, and hydraulic cylinder of its tilting for unloading, mounted hingedly between the chassis frame and the bodywork. The rear side of the body is designed as a carrier-thrower, the chassis wheels of which are made fit into beet inter-row spacings on width and track and arranged in two traces on the same track, which coincides with the track of the towing tractor. Part of wheels of them are made of pivoted flap type and mounted on lever suspensions, and the chassis frame is equipped with a trailer needle and is adapted to connect to the tractor through its hitch attachment according to the scheme of the semitrailer.

Invention relates to agriculture and can be used to provide a method of non-traumatic loading and unloading tuberous roots from harvesting agricultural machines, such as potato harvesters. The method consists in the fact that flexible diaphragms are the first designed and then made as autonomous structures that can be easily mounted and removed from the body of the vehicle or a tractor trolley. The internal cavity of the said diaphragms is filled with air, equipped with a compressor with an air-filter, safety and outflow valve so that it is actuated only at a certain load, and gradually discharges air from the interior cavity of the diaphragm to the complete use of its height. After that, tuberous roots are transported to the warehouse, and there while unloading the similar flexible diaphragms are used, which are mounted first on self-propelled devices. If necessary, they are rolled under the vehicle or a tractor trolley, the products are unloaded in them, transported in to the desired location in the warehouse and placed for long-term storage. To return the flexible diaphragm to its original state the compressor is actuated, air is injected into the diaphragm to actuating the safety valve, and it is provided that the original form of the flexible diaphragm is not convex, but U-shaped.

Diaphragm for non-traumatic handling of tuberous roots consists of base and frame (1), made as rectangular rigid spatial bar structure with double bottom (2). Walls are made solid and rigidly mounted on bars of base or frame (1). Inside the frame, flexible diaphragm (4) is attached to bottom with possibility to be filled with air from common compressor (5) with control panel (6). To side walls of the frame (1), flexible belt (7) having width equal to diaphragm (4) length is rigidly attached. Near bottom this belt forms narrow loop (8) and passes upwards without being rigidly attached to diaphragm (4) material. At the top, the belt (7) is rigidly attached to diaphragm (4) material and can be made of polyurethane foam or in combination. Profile of diaphragm (4) when being filled with air forms trough shape. At the top of front wall, pneumatic chute is rigidly attached being possible to fold and unfold depending on feeding or removing air to/from it. The chute is made of flexible material, and its outer surface is covered with polyurethane foam. From below, along centerline near the front wall pneumatic cylinder with air stock under pressure of 100-150 MPa inside the cylinder is attached. The cylinder has drain valve and exhaust valve. Cross profile of the chute is trough-shaped. From below of the chute, horizontal rectangular concavity is formed where horizontal rigid link (9) is stretched. Its one end is pivotally attached to the front wall of the said concavity, and the second end is rigidly connected with tape-coil spring. There can be several such devices installed along a wall with equal pitch.

Group of inventions can be used for cleaning and loading of sugar beet from the field pile into the vehicle. The method of operation of the unit as a part of the tractor and the loader-cleaner of root crops includes periods of presence of the loader-cleaner at the field pile of root crops waiting for the arrival of the vehicle for removal of root crops and periods of operation of the loader-cleaner on arrival of the next vehicle. The root crops, soil impurities, and crop residues are taken from the field pile by the loader-cleaner and sent to the cleaning units. They are then partially purified by movement to the loading elevator, and then loaded into the back of the vehicle. During the periods of presence of the loader-cleaner at the field pile of root crops waiting for the arrival of the vehicle, the root crops and soil impurities are taken from the field pile by the loader-cleaner and sent to the cleaning units, cleaned from impurities and moved to the cross conveyor which places a pile of root crops with the remaining impurities in the new field pile on the opposite side from the loading elevator. Upon arrival of the vehicle the cleaned root crops and remaining impurities are taken from the new field pile, re-cleaned and moved to the loading elevator which loads twice cleaned pile of root crops with reduced remaining impurities in the back of the vehicle.
