DEVICE FOR VENTILATION OF AGRICULTURAL PRODUCTS Russian patent published in 2015 - IPC A01F25/08 

FIELD: agriculture.

SUBSTANCE: invention relates to the storage of field husbandry and horticulture products, in particular to the means of ventilation, and can be used in grain storages, vegetable stores and other premises intended for the bulk storage of agricultural products. The device for ventilation consists of perforated sections interconnected with overlapping, each of which is made in the form of an arch with a wavy surface, provided with connecting elements. The connecting elements are mounted in the area of action of the largest unbending load acting at the base of the arch. The connecting elements are made of galvanized steel having a thickness of 0.7 mm to 2.2 mm and a length corresponding to the distance between the bases of the arch. The connecting elements have the bending on the edges at an angle of 90°, with the height corresponding to a height of the section corrugation. The upper bending is provided with a stop deflected from the vertical at an angle of 15° to 30°. The width of the connecting element is from 1.5 to 2 distances between the pitch of the corrugation vertices of the perforated section having the shape of an arch.

EFFECT: invention provides increased stiffness and structural stability.
