GRAIN DETECTOR IN COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a grain detector in a combine harvester capable of preventing the influence of the scattering and abutting of grains blown off to a hopper tank, eradicating the damages and play of a grain detection sensor main body, its connection wire and an attachment bracket, etc., and improving the reliability of a grain detection operation. ;SOLUTION: A first grain detection sensor 14 for detecting the accumulation of the grains inside the hopper tank 10 is mounted to the downstream side of a blow-off direction A of an upper blow-off port 9a and a second grain detection sensor 15 is mounted to an upper position reaching to the downstream side of the blow-off direction A further from the attaching position of the mounted detection sensor 14.;COPYRIGHT: (C)1998,JPO
