FIELD: agriculture. ^ SUBSTANCE: invention relates to agriculture and can be used for harvesting forage and other hay-straw materials in rolls. A device for final drying of agricultural crops rolls contains air-feed channel with the air distribution surface, a mechanism controlling the air supply, connected through a control unit with the air temperature sensor, of inlet and outlet of the object. On the air-feed channel a flow velocity sensor is installed, and on the side opposite to the air supply, at equal distances of the diameter from the flow velocity sensor, which is located in the center of the roll end, two flow sensors are additionally installed, at that the air-feed channel is connected to the distribution chamber, which lower wall is set at an acute angle a, and on the upper wall an outlet is made with an area of 60-80% of the area of the roll end, and on the perimetre of the opening a board is rigidly fixed. ^ EFFECT: invention enables to simplify the final drying of forage and hay-straw materials. ^ 5 dwg |
