Harvester grain tank monitoring system and harvester provided with same

Abstract

The invention relates to a harvester grain tank monitoring system and a harvester provided with the same. The system comprises a grain tank heating device, a grain height monitoring device and a graintank grain damage state monitoring device. According to the system, through combinations of convex lenses and plane mirrors, light rays are used for assisting an operator in observing a grain tank and the real-time state of grain in the grain tank, and the grain in the grain tank is heated. The convex lenses can collect the light rays, the plane mirrors can reflect the light rays, and the combination of the two convex lenses different in focal length can be used for amplifying and heating the grain. Power supplies, sensors, algorithms, control systems and the like required by traditional combined harvester working state monitoring modes are removed, and the operator can visibly understand the grain tank and the loading amount and real-time state of the grain in the grain tank and heat thegrain in a mode with a simple structure, a low cost and high reliability.

Description

technical field [0001] The invention belongs to the technical field of manufacturing and monitoring of grain harvesting machinery in agricultural machinery, and in particular relates to a harvester grain tank monitoring system and a harvester equipped with the system. Background technique [0002] When the combine harvester is working in the field, the newly harvested grains are usually directly transported to the grain tank for storage through the conveying pipeline (grain auger), and the moisture content of the newly harvested grains is generally above 24%. If they are not dried in time, Grains will become moldy and affect consumption. Post-harvest grain loss caused by mildew in my country is as high as 21 million tons each year, accounting for about 4.2% of the country's total grain output, resulting in direct economic losses of 20 billion yuan. [0003] In addition, domestic combine harvesters are relatively low in intelligence, generally lack working parameters and per...
