Embodiment approach

[0040] In this embodiment, a crawler combine harvester is taken as an example to describe the present invention in detail. figure 1 and figure 2 Shown is an embodiment of the grain tank monitoring system of the present invention. The grain tank monitoring system includes a grain tank heating device 1 , a grain height monitoring device 2 and a grain tank grain damage state monitoring device 3 .

[0041] Such as image 3 and 4 As shown, the grain tank heating device 1 includes an outer wall shell 101 and an inner wall shell 102; a light-gathering layer is arranged between the outer wall shell 101 and the inner wall shell 102, and the light-gathering layer will The light converges to the inner shell 102 .

[0042] In this embodiment, the light concentrating layer may include multi-layer convex lenses. Preferably, the light concentrating layer includes several first convex lenses 103 and second convex lenses 104; the second convex lenses 104 are installed on the inner wall sh...

Abstract

The invention relates to a harvester grain tank monitoring system and a harvester equipped with the system, including a grain tank heating device, a grain height monitoring device and a grain tank grain damage state monitoring device. The system uses a combination of a convex lens and a plane mirror to assist The operator observes the real-time status of the grain tank and the grain inside it, and heats the grain in the grain tank. The convex lens can gather light, and the flat mirror can reflect light. The combination of two convex lenses with different focal lengths can magnify and heat the grain. Get rid of the power supply, sensor, algorithm, control system, etc. required by the traditional monitoring method of the working condition of the combine harvester, and the operator can intuitively understand the grain tank and its internal grain with a simple structure, low cost, and high reliability. The real-time status of the loading and status of the grain, and heat treatment of the grain.

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...
