摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the agriculture. Disclosed is a device for accumulation heating of soil on fields, consisting of a heating chamber, in which there is an elastic sealed container and suction air inlet branch pipe. Fixed cover plate with holes is installed above the intake air inlet branch pipe, at the top of the cover there installed is a flat movable disk with holes that are made with possibility of coincidence with the holes of the fixed cover. On one side to flexible movable disc there is an elastic sealed container, which is configured to be compressed and straightened depending on air temperature, and also be in interrelation with support, walls of which are made of corrugated material, and on the other side flat movable disc is engaged with upper end of lever, on which load is suspended.;EFFECT: invention provides higher yield capacity.;1 cl, 2 dwg
