FIELD: drying equipment for loose agricultural materials, for instance grain, in stationary and/or field conditions. SUBSTANCE: rotary grain drier uses at least one middle and two extreme units forming a horizontal row for rigid fixing of their position and the position of the components relative to one another; each unit has a complete set of components corresponding to it in height. The grain drier has a feeder of the material to be dried and an unloading installation attached to a three-dimensional frame. The middle unit is made in the form of the respective section of the base with drive and supporting rollers, with the central support and drive of the drying chamber bottom. with part of the three-dimensional frame corresponding to the middle unit, exterior guard and drive perforated bottom with an interior guard of the drying chamber, for instance with the unloading installation in the form of a drive screw, with shutoff device of the grain lower layer and independent drive, with a feeder and air conduit; and each extreme unit is made in the form of the respective sections of the base with supporting rollers and with respective segments of the three-dimensional frame of the exterior guard and drive perforated bottom of the drying chamber. EFFECT: prevented influence of assembly conditions in situ on serviceability of the grain drier due to assembly of its units at the manufacturing plant and joining in situ. 10 cl, 5 dwg |
