Real time monitoring method for random loss rate of combine

A combine harvester, real-time monitoring technology, applied in the direction of harvesters, agricultural machinery and implements, cutters, etc., can solve the separation performance, separation performance, cleaning performance is unstable, unaware of grain moisture and loss rate, no simultaneous testing The performance parameters of the combine harvester, such as random feeding amount, the ratio of grass to grain, the moisture content of grain, and the rate of grain loss, can improve production efficiency and operation quality, reduce labor intensity, and improve work efficiency.

Problems solved by technology

Therefore, the feeding amount of the combine harvester is an uncertain quantity that changes randomly, and it is impossible to carry out real-time testing by manual methods; and the working parts such as the threshing mechanism, separation mechanism and cleaning mechanism of the combine The continuous change of input, grass-to-grain ratio, and grain moisture leads to the instability of detachment performance, separation performance and cleaning performance, resulting in random changes in the operation quality of the combine harvester, especially the loss rate
Therefore, without knowi

Embodiment Construction

[0020]The working principle and implementation process of the monitoring system of the present invention are as follows: figure 1 and figure 2 As shown, the monitoring system implementing the real-time monitoring of the random loss rate of combine harvesters is composed of the following parts: signal acquisition part, signal conditioning part, signal conversion part, computer (such as single-chip computer, portable computer, desktop computer, etc.) analysis Processing part, interface circuit, display and alarm device and other parts. The signal acquisition part includes: feed amount sensor, grain harvest sensor, grain loss sensor (cleaning loss sensor, separation loss sensor), grain moisture sensor (stalk moisture content sensor, grain moisture content sensor), etc.

[0021] When the combine harvester is harvesting in the field and monitoring the random loss rate in real time, the header feeds the grain through the bridge equipped with the feed amount sensor, and the sensor ...

Abstract

The present invention relates to real-time monitoring method of random loss rate of combine. Feeding sensor, seed collecting amount sensor, seed loss sensor and grain moisture sensor are used simultaneously the acquire loss rate related signals, the signals are regulated, A/D converted and transmitted to computer for processing and analysis, and the results are fed via interface circuit to display and alarm device for the display and alarm of feeding amount, straw/grain ratio, grain moisture, separation loss rate, sorting loss rate and total loss rate. The present invention can measure the random loss rate and monitor the main factors to affect the loss rate and thus the operation state of the combine, so as to ensure the high operation quality of the combine.

Description

Technical field: [0001] The invention relates to the technical field of field monitoring of agricultural equipment, and relates to a method for real-time monitoring of the random loss rate of a combine harvester. Background technique: [0002] When any combine harvester is harvesting in the field, no matter how its operation quality is, there will always be a loss rate of a few percent, and the loss rate is instantaneous and dynamic. However, the loss rate of the harvester must meet the technical requirements of relevant Chinese national standards (such as GB / T 8097-1996, loss rate of threshing machine: wheat≤1%, rice≤3%). Therefore, when harvesting operations, only demanding that the harvesting area is large and the harvesting grains are many, regardless of the loss rate and the operation quality of the combine harvester is not liked by farmers and operators, and is not welcomed by the market. [0003] Currently, for the test of combine harvester harvest loss, manual metho...
