Real time monitoring method for random loss rate of combine

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...

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 knowing the random changes in feed amount, grass-to-grain ratio, grain moisture and loss rate of the combine harvester, it is impossible to control the harvester to work in the best working state to improve the production efficiency of the harvester and ensure the good working quality of the harvester

The existing loss and loss rate testing methods do not simultaneously test performance parameters such as the random feeding amount, grass-to-grain ratio, grain moisture, and grain loss rate of the combine harvester, and cannot effectively monitor the random loss rate of the combine harvester.
