Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ejector apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ejector apparatus and a cargo transportation vehicle having the ejector apparatus. More particularly, the present invention relates to an ejector apparatus capable of discharging a load without a remaining amount of a load and capable of unloading even in a low- The present invention relates to a cargo transportation vehicle.

Generally, a dump truck refers to a special freight vehicle that is tilted by 60 to 70 ° with the load and automatically loads the load such as soil and aggregate, and is also referred to as a dump car.

Dump trucks are more maneuverable than other haulage machines and are suitable for long haul transport and are suitable for transporting dirt, sand, gravel and the like. There are various kinds of loading capacity such as 2 ~ 50t. The slope of the loading box is usually hydraulically operated, but may be mechanical or manual.

The dump truck was originally built and used in the middle of construction, but due to the advantages of its own unloading function, it is also used for cargo transportation in addition to construction.

The dump trucks are divided into four types according to the direction of the slope of the loading box: a side dump truck, a rear dump truck, a three-way open dump truck, and a bottom dump truck. The side dump truck is a structure that the side of the loading box is attached to the chassis so that the loading box can be tilted sideways. Rear dump trucks are most commonly used as trucks with the rear of the loading deck attached to the chassis and tilting the loading deck to the rear. A three-way open dump truck is a truck that can be tilted either to the left or to the rear. And, the bottom dump trucks are often used for trailer dump trucks with the bottom of the loading box open and the load down.

A dump device for a dump truck is disclosed in Korean Utility Model Publication No. 1998-0035708 (published September 15, 1998). In the dump truck dump device of the above prior art, a loading / unloading device is lifted / lowered by a dump truck dump device in both directions, so as to facilitate the unloading operation of the cargo according to the workplace conditions.

However, the dump truck for the dump truck of the above prior art has the loader raised to one side so that the load loaded on the loader is lowered. Therefore, there is a problem that the dump device having such a configuration can not be unloaded in a low ceiling space.

In addition, such a dump device has a problem that a lot of remaining amount is left in the loading box when the load contains a lot of moisture or is wet.

Also, in the case of a dump truck having such a dump device, there may be a risk that a rollover accident may occur when the ground of the cargo is uneven or inclined.
