Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery discharge preventive device for agricultural machinery,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for preventing discharge of an agricultural machine battery, and a battery cover for an agricultural machine, and more particularly to a battery cover for an agricultural machine battery which is easily installed in an agricultural machine such as a cultivator, To an apparatus for preventing discharge of an agricultural machine battery and a battery cover for an agricultural machine which can extend the life of the battery and stabilize starting by suppressing the occurrence of natural discharge of the battery.

Traditionally, a farming machine such as a cultivator has mainly adopted a method in which an operator turns a steering wheel to start an engine. In recent years, a self-starting structure including a battery and a starting motor has been provided so that starting can be performed by driving a starting motor .

In addition, although the conventional farm machinery is driven mainly by driving the engine, recently, it has been transformed into a form of running or performing various functions by driving an electric motor.

In addition, in the related art, a generator is installed in an engine to charge the battery during the driving process of the engine. In addition, a battery for supplying driving current to the starter motor or the electric motor And the like.

On the other hand, the farm machinery is used periodically in the farming season, but is left in a parked state without operating in the farming season.

However, a battery that is mounted on the agricultural machinery and supplies driving current to the starting motor or the electric motor has a natural discharge when left for a long time due to its characteristics, and when the natural discharge is continuously performed, the battery is in a completely discharged state.

If the battery is completely discharged, the charging efficiency and service life of the battery drop rapidly, and if necessary, the starting motor or the electric motor can not be driven. Therefore, the starting ability of the agricultural machine can not be achieved.

Of course, this phenomenon can be solved when the operator periodically runs the farm machinery in the concentrated period or charges the battery through the charger, but it is practically difficult to effect such periodic charging substantially.
