Problems solved by technology

[0003] At present, the monitoring of the cleaning loss rate is mainly calculated by manual cleaning and separation. Although the monitoring results are relatively accurate, the detection efficiency is very low and the labor cost is high.
Scholars at home and abroad have done a lot of research on the loss rate of combine harvesters, but the system can only qualitatively display the change law of the loss rate, and cannot quantitatively display the current loss rate
Research on grain loss rate has been carried out in China, and some achievements have been made, but the overall technology is still not perfect

Abstract

Disclosed are a detection device and method for the cleaning loss rate of a grain harvester. The device comprises a feeding mass detection unit, a loss quantity detection unit, a signal processing circuit and a secondary instrument; the total loss quantity and feeding mass of grains are obtained, and the cleaning loss rate of the grain harvester is calculated. According to the detection device andmethod for the cleaning loss rate of the grain harvester, on the basis of a sensor technology and a computer image processing technology and in combination with a scientific mathematical model, real-time monitoring of the cleaning loss rate is achieved, a traditional manual cleaning mode is changed, and a lot of manpower and material resources are saved. Meanwhile, a harvester driver can reasonably change operating parameters of the harvester according to the change law of the loss rate, and the operating performance and the working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a device and method for detecting the cleaning loss rate of a grain harvester. Background technique [0002] With the popularization of grain combine harvesters in my country and the continuous improvement of mechanization level, the automation and intelligence of machinery have become a major trend in the development of machinery. Among them, the cleaning loss rate is one of the important indicators to measure the performance of combine harvesters. Therefore, it can be accurately and real-time Monitoring the harvest loss rate of grains is of great significance to the realization of precision agriculture. [0003] At present, the monitoring of the cleaning loss rate is mainly obtained through calculation after manual cleaning and separation. Although the monitoring results are relatively accurate, the detection efficiency is very low and the labor cost is high. Sch...
