To generate electric power by effectively using falling energy of power/grain, and to prevent the damage by absorbing falling shock of the powder/grain by providing an impeller for rotating by natural flowing-down of the powder/grain and a generator rotatably driven by the impeller, and connecting the generator to a load.
An end part of a chute pipe is provided with a shock absorber composed of a generator C having a stator 3 by winding an armature coil 2 on an iron core, a rotary field part 4 being a magnetic pole for generating a magnetic field in this center and an impeller 7 for coaxially rotating on a rotary shaft 5 located at the center and installing an abrasion resistant member 6. Electromotive force is generated in an armature (the stator) 3 by rotating the rotary field part 4 by rotating the impeller 7 by colliding powder/grain becoming a high speed by naturally flowing down in a chute pipe with the impeller 7 to generate AC electric power to thereby prevent abrasion of the chute pipe and damage of the power/grain, and flowing-down energy of the powder/grain is effectively used to be converted into electric power.
