Abstract

Provided is a combine capable of harvesting an appropriate amount of grains according to a free capacity of a drier, while reducing trouble for a worker. A harvest amount sensor is capable of a first determination U 1 for determining the grain storage amount intermittently during reaping traveling of a traveling vehicle body and a second determination U 2 for determining the grain storage amount based on a manual operation during stopped state of the traveling vehicle body. A calculation section is configured to calculate the total harvest amount based on a first determination amount M 1 by the first determination U 1 and a second determination amount M 2 by the second determination U 2 . A decision section is provided for deciding whether the total harvest amount has exceeded the target storage amount MI based on a requested grain amount requested by a drier, or not. An informing section is provided for effecting completion informing T 3 if the decision section decides that the total harvest amount has exceeded the target storage amount MI.

First claim

The invention claimed is:

1. A combine for harvesting grain based on determining a grain storage amount, the combine comprising:
a harvest amount sensor capable of determining the grain storage amount of grains stored in a grain storage section;
a communication section of a control device, the communication section being capable of communication with an external drier;
a setting section capable of setting a target storage amount based on a requested grain amount requested by the drier;
a calculation section of the control device, the calculation section being capable of calculating a total harvest amount based on the grain storage amount determined by the harvest amount sensor;
the harvest amount sensor being capable of a first determination for determining the grain storage amount intermittently during reaping traveling of a traveling vehicle body and a second determination for determining the grain storage amount based on a manual operation during stopped state of the traveling vehicle body;
the calculation section being configured to calculate the total harvest amount based on a first determination amount by the first determination and a second determination amount by the second determination;
a decision section of the control device, the decision section being capable of deciding whether the total harvest amount has exceeded the target storage amount or not; and
an informing section of the control device, the informing section being capable of effecting completion informing if the decision section decides that the total harvest amount has exceeded the target storage amount.

2. The combine of claim 1 , wherein:
the setting section can set a preliminary target amount which is less than the target storage amount;
a preliminary informing different from the completion informing is effected when the total harvest amount exceeds the preliminary target amount.

3. The combine of claim 2 , wherein informing different from both the completion information and the preliminary informing is effected if a grain culm sensor for detecting grain culm at a reaping section becomes non-detection state when the total harvest amount is present between the target storage amount and the preliminary target amount.

4. The combine of claim 2 , wherein:
the combine further comprises:
a reaping clutch for engaging/disengaging power transmission to a reaping section; and
a threshing clutch for engaging/disengaging power transmission to a threshing device; and

wherein the reaping clutch and the threshing clutch are brought into disengaging state respectively if a grain culm sensor for detecting grain culm at the reaping section becomes non-detection state when the total harvest amount is present between the target storage amount and the preliminary target amount.
