FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building. Device for venting and transporting the grain heap contains an aerial duct separated by a load-bearing perforated partition into the air supply and transport parts. Aerial duct is a frame, covered with a cloth. Outer walls of the air chute and the central air distribution channel are made of airtight and water-repellent fabric, and the inner side walls are made of cloth for sieves. Cavities formed by them serve to distribute and introduce additional air flow into the grain layer.
EFFECT: proposed design provides an improvement in the quality of pre-treatment of grain heaps, a reduction in the metal content of the structure, and the energy intensity of the process.
