UNIT FOR PRODUCING BUTTERFLIES OF ANGOUMOIS GRAIN MOTH

摘要

A unit for producing butterflies of grain moth comprises a cylindrical grain container with perforated tubes, mounted inside, a moth collector, a mixing unit as a screw with a drive, a fan for cooling the grain, a device for moistening thereof, a panel for controlling a drive of the screw and a fan by signals of a temperature control sensor disposed in the grain. The tubes are arranged by concentric rows and mounted into cups in the cone bottom by lower ends thereof. The upper part of each of the cups is made as a cone one, and the lower part is equipped by a stopper for a pipe. The upper ends of the tubes with removable plugs are arranged above the upper end of the grain container as a cone. A flange for fixing the drive of the screw is made as a complex one and comprises a floating flange with a resilient liner, glued thereto, and a pilot fillet. The flange for fixing the screw is mounted above the floating flange and connected thereto with the aid of legs. Between the flanges a connection of the screw shafts and drive thereof is arranged, as well a distributing disk with a piping fixed thereabove put on the shaft of the screw. In the lower part of the grain container each of the concentric row of the tubes, excluding the internal one, is equipped with a cone partition equal thereto by the diameter, resting on the bushings, which are fixed on tubes equidistant between each other in each of the rows, excluding the outer one. The cone partitions are arranged one above the other with a gap, diameters thereof are increased in the direction to the cone bottom. A holding cage with the netted bottom is pressed to the end of the moth collector. The unit is supplemented with a netted enclosure resting on the floating flange and the upper end of the grain container, and also with a suction hood resting on the body of the drive of the screw, those are mounted for the flying period of butterflies.
