A monitoring device and method for monitoring impurity content of grain grains

Abstract

The present invention provides a monitoring device and monitoring method for impurity content of grain grains, which is located outside the grain transporting device. The side wall of the grain transporting device has a grain picking port and a grain unloading port arranged up and down. The detection device includes: a grain picking device , installed at the grain collection port; the grain unloading device is installed at the grain unloading port, located below the grain collection device, and connected to the grain collection device through the first pipeline; the grain miscellaneous separation device includes a suction mechanism, an air flow pipe, and a miscellaneous collection barrel and the filter screen, the suction mechanism communicates with the top wall of the miscellaneous collection bucket through the airflow pipe, the side wall of the miscellaneous collection bucket communicates with the first pipeline, and the filter screen is placed in the miscellaneous collection bucket and is located above the first pipeline; The residual detection device includes a control device and two pressure sensors respectively installed at the bottom of the residual collection bucket and the bottom of the grain unloading device; the invention can monitor the trash rate of grain grains online, so that the operator of the harvester can know the trash content in the grain box in real time. remaining information.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a monitoring device for impurity content of grain grains. Background technique [0002] The impurity content of the grain is an important indicator of the harvesting performance of the combine harvester. In my country, there are few existing technologies related to the real-time automatic monitoring device for the impurity content of the grain of the combine harvester. It is found through literature search that the prior art discloses a grain cleaning and The impurity content monitoring device is mainly used to sort and detect the impurity after the grain is harvested, and calculate the weight of the grain and the impurity respectively, and calculate the impurity content. Miscellaneous information in the box. The prior art also provides a detection device for real-time detection of the impurity rate in the grain tank by acquiring an image of the grains in the grain tank and p...
