Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizing apparatus for a rice transplanter, for example, in a multi-row rice transplanter having eight or more rows, wherein lateral row fertilization is simultaneously performed during seedling planting work.

[0002]

Conventionally, fertilizer in a fertilizer hopper mounted on the machine is conveyed to the vicinity of a planting position by an air flow fed from a fertilizer blower to perform fertilization. The fertilizer blower is driven regardless of the engine, and the fertilizer blower can be driven even when the engine is stopped. However, when the fertilizer blower is driven, a current of, for example, 20 A or more is consumed. Therefore, when the engine is stopped, the amount of discharge is large and the battery is in an overdischarged state.

[0003] Normally, the low idling speed of the engine is maintained at a constant low speed (for example, about 1000 rpm) irrespective of the running time during work. However, when the low idling speed during the planting operation is low, The power generation capacity of the alternator and the charging capacity of the battery are not sufficient, and there is a disadvantage that the electric capacity is insufficient when the fertilizer blower is driven.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a fertilizer application system for a rice transplanter that conveys fertilizer by an air flow from a fertilizer blower, including an electronic governor for controlling the rotation output of an engine, and the electronic governor. The blower driving means for driving the blower by an output signal from the control unit is provided, the driving of the fertilizer blower is also stopped while the driving of the engine is stopped, and the fertilizing blower is driven only during the proper driving of the engine, It is intended to effectively extend the life of the battery.

Further, a lowering signal of the planting portion is input to the control portion of the electronic governor, and the low idling rotation of the engine is increased by a certain value when the planting portion is lowered, so that the low idling rotation of the engine during the planting operation is performed. In this state, the amount of electricity supplied from the alternator and the battery when the fertilizer blower is driven is increased to prevent the battery from being over-discharged, and to enable the fertilizer blower to always be driven favorably.
