Device and method for monitoring residual capacity of grain tank and residual walking distance of combine harvester

Abstract

The invention provides a device and method for monitoring the residual capacity of a grain tank and the residual walking distance of a combine harvester. The device comprises the grain tank, a detection device, a control panel, a control unit and a warning device, wherein the detection device is used for detecting average distance information from the stacking surface of grains in the grain tank to the top of the grain tank and transferring the average distance information to the control unit; and the control panel is used for at least inputting information including a cross section area of the grain tank, the height of the grain tank, the cutting width of the harvester, the grain yield per square meter and the unit weight of cereal grains and transferring the information to the control unit. By monitoring the residual space in the grain tank in real time, the residual walking distance of the combine harvester during harvesting working is calculated and is displayed in a display in a cab in real time, so that a tractor driver can be assisted to plan a harvesting route and an unloading route, the idle stroke of the combine harvester during field walking is shortened, and the harvesting working efficiency is improved; and when the capacity of the grain tank is about to be used up, a light-emitting diode cooperates with a buzzer to raise the alarm to remind the tractor driver to timely unload the grains, so that the loss caused due to leakage of the grains is avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a monitoring device and method for the residual capacity and remaining travel distance of a grain tank of a combine harvester. Background technique [0002] In recent years, with the promotion of grain combine harvesters in my country, the work efficiency of grain harvesting operations has been greatly improved. Among them, due to the characteristics of partitions and blocks in my country's farmland and no large-scale planting, small and medium-sized combine harvesters have been widely used. During the operation of the small and medium-sized combine harvester, the harvested grains will be temporarily stored in the grain tank. After the grain tank is full, the combine harvester will drive to the side of the field ridge for unified unloading of grain. In contrast, when harvesting crops on a large scale in foreign plains, large combine harvesters and grai...

AI Technical Summary

Problems solved by technology

[0004] 1. The grain tank of the combine harvester is made of opaque metal plate. The machine operator cannot grasp the accumulation of grain in the grain tank. If the grain unloading work is not timely, there may even be grain leakage, resulting in losses;

[0005] 2. The grain tanks of small and medium-sized combine harvesters are generally small. When the machine often drives to the center of the field, the grain tank alarms. At this time, the operator needs to drive the combine harvester to the ridge to unload the grain, which greatly reduces the work efficiency;

[0006] 3. When harvesting ratooned rice in Hunan and other places, the frequent unloading actions of small and medium-sized combine harvesters will increase the rolling of the machine in the field, resulting in reduced rice production in the second season and increased economic losses
