Abstract

PURPOSE:To save fuel by a method wherein an engine and an electric system are automatically turned off after a specified time has elapsed by an automatic cutting device when a combined harvester and thresher is stopped. CONSTITUTION:In harvesting work whereby a direction of a machine is changed while it is sequentially driven around four corners, when the machine is automatically stopped by detection of a full level of a grain level sensor 41 of a grain tank and a grain storing bag is taken out of the machine by an operator, this is normally done within two or three minutes. When a constant time specified to two or three minutes has elapsed, rotation of an engine 1 is stopped by fuel cut by a fuel cut motor 13 with an automatic cutoff device 2, and after stopping of the rotation is verified by a rotation sensor, the electric system is sequentially turned off by a power source relay 42.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a power cutoff system for reaping machines, and more particularly, to a system for automatically shutting down the power system of a combine harvester, tractor planter, etc., which can be operated automatically, depending on the status of the stopped state during operation. It can be used when blocking etc.

Background Art and Problems to be Solved by the Invention In recent years, various types of work machines that can be operated automatically have been increasing. When retrieving from the machine, there are many opportunities to stop the work equipment due to incidental processing factors such as replenishing paper for the knocks used to bind the ejection slots and cutting pillows for turning headlands, and during this stop, At first, it is often the case that the engine is left running, based on the judgment that there is no need to turn off the engine every time the vehicle is stopped for a short period of time. However, in many cases, what was intended to be a short stoppage time ends up being surprisingly long due to various circumstances, and in the end, there are cases where it would have been possible to save fuel by turning off the engine from the beginning, but on a daily basis there is no resistance at all. If these are integrated, it will be a big loss.

This invention has been made in accordance with the above-mentioned situation, and is designed to automatically shut off the power system when the reaping machine is stopped for a certain period of time.

Means for Solving the Problems This invention reaps a row of shell culms (A) and automatically turns the cutting end (A) of this row of shell culms (A) in a horizontal direction toward the next reaping path. I will try to move on! Thi! In a reaping work machine that can be rotated, when the reaping work machine is stopped and the stopped state has passed for a certain period of time, the engine (1
) is set to 0FFI, and an automatic shutoff device (2) that turns off the electrical system thereafter is provided.

Functions and Effects of the Invention In a reaping machine capable of automatic operation, for example, when a de-AF11 grain storage bag is taken out of the machine, it is necessary to replenish strings for the knocks that bind the discharge culm, or to turn the headland. Due to incidental processing factors of reaping work such as pillow cutting, there are many opportunities to stop the work equipment, and when this stops, the machine remains stopped for a certain period of time, for example, the processing time required for the incidental processing in normal conditions (normally (up to about 2 to 3 minutes), the automatic shutoff device (2) installed on the work machine first automatically turns off the engine (1), and then automatically turns off the electrical system. This is to turn it off.

As mentioned above, when the work equipment is stopped for ancillary processing, if this stopped state has elapsed for a certain period of time,
By automatically turning off the engine (1) and the electrical system through the action of the automatic shut-off device (2), even if the stoppage time was originally intended to be only a short time, but due to various circumstances, the stoppage time becomes unexpectedly long. Also, since the power system 1 is automatically turned off after a certain period of time has elapsed, the saving effect by preventing wasteful use of fuel is significant.

After the rotation sensor (12) confirms that the rotation has stopped, the electrical system is subsequently turned off by the power relay (42).

In addition, the above-mentioned effect can be applied even when the combine harvester is stopped for other operations other than taking out the grain storage bag, such as replenishing strings for the knocks that bind the discharge culm, cutting pillows for turning headlands, etc. The engine (1) and the electrical system are turned off after a certain period of time according to the above.

As described above, when the combine harvester is stopped for ancillary processing, the engine (1) and electrical system are automatically turned off after a certain period of time due to the action of the automatic shut-off device (2).
Since the fuel is turned FF, there is a great saving effect by preventing wasteful use of fuel.

Further, the present invention can be applied not only to combines but also to tractors, planters, etc.
