A precise control device and control method for grain unloading on the ground of a harvester

Abstract

The invention discloses a precise control device and method for grain unloading of a harvester at the edge of a field. The precise control device for grain unloading at the edge of the field comprisesa control module, a detection module capable of detecting the state of grain in a granary in real time, a GPS module capable of acquiring the position of the harvester in real time, a display moduleand an alarm module; under the circumstance that the control module judges that the harvester turns around based on position coordinates fed back by the GPS module, the control module calculates and stores the residual capacity of the granary when the harvester turns around at this moment or turns around in the even number time and calculates the grain output of the field operation of the first section / the first two sections, and by contrasting the calculated grain output with the residual capacity, it is judged whether or not at present, the granary can accommodate the output grain of the field operation of the next section / the next two sections; if not, a driver is reminded of unloading; if yes, the field operation continues. The precise control device and method can effectively avoid that the harvester returns back in the harvesting process, the harvesting operation efficiency is greatly improved, and the labor intensity of the driver is reduced.

Description

technical field [0001] The invention belongs to the technical field of harvester unloading grain, and in particular relates to a precise control device and control method for grain unloading at the head of a harvester. Background technique [0002] At present, the grain unloading methods of the harvester are mostly divided into three types: unloading grain with the vehicle, unloading grain anywhere, and unloading grain on the ground. For some areas, due to terrain, soil structure, customs, and limited granary capacity, the driver can only choose the way of unloading grain on the field, that is, the harvester unloads grain when it reaches the field during the operation. However, this method of unloading grain has the following problems. The way of unloading grain on the field can only rely on the driver's experience of grain output to judge whether the granary can accommodate the grain output harvested to the next field. And in the harvest operation process, the driver will ...

Problems solved by technology

It not only affects the operation efficiency, but also causes unnecessary waste of energy, especially in the operation of long plots.

To be on the safe side, unload the grain regardless of whether the granary is full when it reaches the field, such frequent unloading will seriously reduce the efficiency of harvesting operations and increase the labor intensity of the driver.
