POTATO DIGGER

摘要

The utility model relates to agricultural engineering, in particular to digging devices used in potato harvesters.;The potato digger contains a frame, plowshares, main and cascade bar elevators, vibration grate, cardan transmission, gearbox, support wheels. An additional working body is installed between the main and cascade elevators - a separation intensifier made in the form of drive shafts, on which cams made in the form of Reuleaux triangles are rigidly fixed. The cams are rubber-coated and rotatable at different speeds. An additional working body is installed between the plowshares and the main bar elevator, made in the form of at least two drive shafts with rigidly fixed cams, made in the form of a regular equilateral triangle with rounded tops and placed on the shafts with one triangle offset relative to the other.;The use of the inventive potato digger allows to increase the separating ability of bar elevators by improving the process of crushing soil lumps.
