Harvester

Abstract

A harvester capable of confirming not only the final total harvested amount of a field but also the harvested amount of the field during harvesting operations. This harvester has: a measuring device (2) for measuring the amount of harvest stored in a harvest box (9) temporarily storing harvest harvested while traveling on a field The measurement status judging section (60), which judges whether the measurement environment of the measuring device (2) is a high-reliability measurement status with high measurement reliability or a low-reliability measurement status with low measurement reliability; the harvest amount calculation section (5), It regards the harvest amount calculated according to the measurement result of the measuring device under the high-reliability measurement condition as the high-reliability harvest amount, and calculates the cumulative harvest amount of the field based on the high-reliability harvest amount; the display part (7), which displays the current Harvested amount and accumulated harvested amount, the current harvested amount is the stored harvested amount of the harvested object box (9) calculated according to the measurement result of the measuring device (2).

Description

technical field [0001] The present invention relates to a harvester that temporarily stores crops harvested from a field while traveling in a crop box. Background technique [0002] Such a harvester performs a harvesting operation while repeatedly storing the harvested product in the harvested product box and discharging the harvested product from the harvested product box. In the combine harvester (one type of harvester) disclosed in Patent Document 1, when the harvest weight switch is operated, the measured weight of the empty grain tank is subtracted from the measured weight of the grain tank storing grains to obtain obtained as the grain weight inside the grain bin and displayed. In addition, when harvesting work is performed continuously in a plurality of fields, the harvested grain weight for each field can be confirmed by operating the total weight switch. However, in this harvester, while repeatedly storing the crops in the crop box and discharging the crops from t...

Problems solved by technology

However, in this harvester, one of the measurement conditions for the grain tank is that the horizontal control is turned off, but the horizontal control is usually performed during the harvesting travel, so the weight of the grain inside the grain tank cannot be measured in real time during the harvesting travel

In addition, at the time of horizontal control execution, etc., it cannot be expected to measure the weight of the grain tank that becomes unstable with high accuracy, so when the grain weight obtained by the measurement as described above is used for calculating the total weight of each field, Total Harvested Grain Weight was incorrect for each field when accumulating the Harvest Grain Weight
