Potato digger digs DEVICE

摘要

The invention relates to the agricultural industry, in particular, to machines for Potato. A drawback of the existing device is the low efficiency of crumbling the soil lumps due to the fact that existing Kartofelekopatel passive plowshares during tuber formation Podkopaev different widths moves thick layer, where tubers and soil lumps adjustment are arranged in 2-3 rows, which leads to deterioration separating properties elevators. The purpose of the utility model is to improve the efficiency of breaking up, authorities potato harvester by applying samokoleblyuschihsya plowshares. This object is achieved in that during the deformation of the spring soil compressed by cleaving - decompressed. Thus, coulter oscillate, which provides crumbling formation, promotion of its ploughshare, reducing draft resistance, and the dispersion of soils in the transverse direction, wherein the cross sectional area of ​​the beds remain constant, but the height of the beds is reduced. The use of this utility model makes it possible to improve the efficiency of potato harvester, through the use of samokoleblyuschihsya plowshares, providing a good tunnel formation, its crumbling, steady progress towards eliminating the elevator and sgruzhivaniya and hovering foliage and crop residues.
