Abstract
The present invention relates to the technical field of agricultural machinery, and discloses an apparatus and a method for monitoring impurity rate and breakage rate of grains in a grain-bin of a harvester, wherein the apparatus cannot only detect the impurity and breakage rates, but also collect impurities in grains, improving the cleanliness of grains in the grain bin through the arrangements of an impurity box, a grain-weighing box and a sieving mechanism; the apparatus stores respectively the grains and the impurities into the grain-weighing box and the impurity box through the sieving mechanism, realizes the separation detection of grain impurity and breakage rates, improves the detection accuracy; and, when detecting the breakage rate, the grains are distributed in mono-layer and sparsely by setting Geneva conveying mechanism and spread scraper, avoiding the obstruction between grains and further improving the visual detection accuracy of breakage rate.
