Description

Oil storage device capable of refueling agricultural machinery {OIL STORAGE APPARATUS CAPABLE OF REFUELING AGRICULTURAL MACHINERY}

The present invention relates to an oil storage device, and more particularly, to an oil storage device capable of supplying oil to agricultural machinery and the like.

Agricultural machinery refers to various machines used for farming, examples of which include a tractor and a combine.

Since these agricultural machines generate power using fuel oil such as diesel or kerosene, additional refueling is required when fuel oil is consumed.

However, moving bulky and slow agricultural machines from farmland to gas stations is inconvenient and may lead to loss of working time required for farming.

In addition, front-line farmers purchase a large amount of oil for refueling multiple agricultural machines as duty-free oil, and then store and refuel at the farmhouse itself.

Therefore, there is a need for a device capable of storing oil and directly refueling agricultural machinery at a place other than a gas station, such as a farmhouse or farmland.

The present invention provides an oil storage device capable of storing oil and refueling agricultural machinery and the like.

The present invention provides an oil storage device that can be provided to agricultural machinery after removing impurities and moisture from oil.

The present invention provides an oil storage device capable of protecting an oil tank from sunlight or other heat sources.

The present invention provides an oil storage device with enhanced user convenience.

An oil storage device according to an aspect of the present invention includes an oil tank in which oil is stored; a protection frame that covers and protects the oil tank; a pallet that supports the oil tank and into which a fork of a forklift can be inserted; a plurality of connecting hoses connecting the oil tank and the fuel gun and flowing oil therein; a pump for forming a flow of oil in the plurality of connection hoses; and a filter for filtering the oil flowing through the plurality of connection hoses.

a reflective sheet disposed between the oil tank and the protection frame and covering the oil tank; and a protective case that covers and protects the oil tank and the protection frame, wherein the oil tank may be double insulated by the protective case and the reflective sheet.

The oil tank is formed by cutting one surface of the protective case, and an observation hole exposing one side of the oil tank; may further include.

The filter includes a plurality of filters, the plurality of filters are coupled, the filter housing for supplying oil to the plurality of filters; may further include.

an earth leakage breaker capable of detecting whether an earth leakage has occurred and cutting off the power supplied to the pump when the leakage is detected; and a processor capable of measuring the operating time of the pump and stopping the pump when it is determined that the operating time of the pump exceeds a predetermined value.

According to the present invention, the oil storage device can store and transport a large amount of oil and can perform refueling work using a fuel gun regardless of location.

According to the present invention, a filter may be provided to filter impurities and moisture from the oil supplied.

According to the present invention, the life of the filter is improved by the improved flow path structure of the filter housing and the replacement cycle of a plurality of filters is synchronized, thereby facilitating the user's filter replacement work.

According to the present invention, since the oil tank can be double insulated by the reflective sheet and the cover case, it is possible to reduce the risk of fire or explosion due to prolonged exposure to sunlight.
