DEVICE FOR AIR BLOWING OF AGRICULTURAL PRODUCTS Russian patent published in 2018 - IPC A01F25/08 

FIELD: agriculture.

SUBSTANCE: invention relates to storage of agricultural products by means of an air blowing device. Device is made in form of a tunnel-like channel, telescopic from the corrugated elements of sheets having the form of half-cylinders. Section of corrugated element is rectangular, trapezoidal, triangular, radial, with holes on the lateral surface and on the valleys. Inner radius of the previous corrugated element is greater than the internal radius of the subsequent corrugated member by the thickness of the sheet. Each corrugated element is provided with a pallet from a sheet whose width is equal to two outer radii of the corrugation, and has a flange along the edges parallel to the longitudinal axis of the airway channel. Height of the corrugated element is constant for all corrugated elements and can not be less than 0.01 of the outer radius of the initial, from the air supply side, of the corrugated sheet member. Holes on the lateral surface and on the hollows of the corrugation have a round or oval shape. Total area of the holes is equal to the cross-sectional area of the initial, from the air supply side, of the corrugated element.

EFFECT: invention provides reduction in the loss of pressure of the air flow in the butt joints and simplification of the installation.
