DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration in which electric power generated by a generator driven by an engine is supplied to a battery through a regulator to charge the battery and to supply electric power from the battery to an electric load.

[0002]

2. Description of the Related Art In the above-described engine generator control mechanism for an agricultural machine, the generator electromotive force is always supplied to the battery through a regulator irrespective of the magnitude of the load applied to the engine.

As described above, in the case where the electromotive force of the generator is used for charging, for example, as shown in FIGS. For those with large electric loads such as blowers,
A large proportion of engine horsepower is consumed for power generation load. Then, when the load on the engine increases, that is, when the running load increases, such as when turning on a ridge or running in Fukada, the load on the engine increases, and the power to the running device is partially charged. And the driving state tends to be heavier due to the driver's bodily sensation. An object of the present invention is to provide an engine generator control mechanism for an agricultural machine that can appropriately control power supply to a battery according to the state of an engine load and improve running horsepower.

[0004]

According to a first aspect of the present invention, there is provided a generator driven by an engine, a regulator for adjusting the output of the generator, and a regulated output from the regulator connected to a motor through a battery. And a control unit configured to stop the charging output from the regulator based on a large load detection result of the engine load detection unit. It is in the point provided,
The operation and effect are as follows. [Effects] That is, an engine load detecting means for grasping the state of the engine load is provided, this load state is detected, and if the engine load is large according to the detection result, the charging output to the battery is stopped. As a result, the electric power required for power generation can be diverted to the traveling drive, and the traveling driving force can be increased. Therefore, the driver feels as if the horsepower had increased.

According to a second aspect of the present invention, there is provided a generator driven by an engine, a regulator for adjusting the output of the generator, and a regulated output from the regulator supplied to an electric load via a battery. And an engine load detecting means for detecting the engine load, and a control means for reducing the charging output from the regulator as the detection result of the engine load detecting means is larger. Yes, its operation and effects are as follows. [Function and Effect] As described in the section of the function and effect with respect to claim 1, when the engine load becomes large, the output for charging the battery is not stopped but the output amount is controlled in accordance with the degree of the engine load. Since the charging output can also be left while limiting according to the degree of the load, the energy supply to the battery can be left.

According to a third aspect of the present invention, in the first or second aspect, the engine load detecting means detects a governor operation position with respect to an engine. And the effect is as follows. [Function and Effect] As described in the section of the function and effect with respect to the first aspect, various means can be considered as means for detecting the engine load. Here, the governor for controlling the engine speed according to the degree of the engine load is used. By employing the detection means for detecting the governor operation position, the state of the engine load can be accurately grasped, and the output for charging can be appropriately controlled.

According to a fourth aspect of the present invention, there is provided the fertilizer according to any one of the first to third aspects, wherein the electric load is fed from a storage hopper. Is a blower for a fertilizer that conveys wind to a fertilization point, and its operation and effects are as follows. [Effects] Since the electric load on the battery is a blower which is a functional component for transporting fertilizer by wind, the power consumption is larger than that of a simple lamp or the like. Therefore, the battery capacity to be charged is also large. This means that a large power generation capacity was required.However, since part of the power generation was no longer consumed for charging, the engine power could be concentrated on heavy loads such as for traveling. The output for charging can be controlled appropriately.
