The present invention relates to a structure that allows the use of compressed air in an excavator called a fork lane, and in particular, to enable the storage and use of compressed air easily without providing a tank for storing compressed air.

As is well known, the excavator is one of the heavy equipments that are very useful in the construction / civil engineering site, the equipment to work in a very harsh working environment, such as a dangerous place or a lot of dust and dirt.

Depending on the working environment and the characteristics of the equipment, the dust inside the driver's seat and the outside of the body should be cleaned from time to time. The necessity of use often occurs, and the conventional excavator was not provided with a device for supplying the compressed air because the place where the tank for using the compressed air can be used was not provided, and thus the compressed air could not be used when needed.

As a result, when maintenance or cleaning is required, the excavator has to travel a long distance, or a maintenance vehicle having a compressor device must be supported, and accordingly, the excavator driver has been subjected to enormous time / monetary waste.

The present invention devised in view of the above problems is that the inside of the boom of the excavator is empty and considerably tightly spaced, so that the boom can be used as a compressed air storage tank to store the compressed air, the excavator Its purpose is to make the use of compressed air convenient and useful during use or maintenance.

The present invention installs an air compressor that operates by using electricity at any position of the excavator and connects the battery of the excavator to operate the air compressor, the boom is connected to the inlet and compressed air from the compressed air generated from the air compressor By installing a connector and a safety valve that can be used to store the air generated from the air compressor in the inner space of the boom bar, characterized in that for use, the following detailed description of the preferred embodiment of the present invention according to the accompanying drawings Looks like this:

Brief Description of Drawings Fig. 1 is an overall outer sectional view of a main portion of an excavator according to the present invention, and Fig. 2 is a main configuration diagram of an excavator according to the present invention.

The present invention installs an air compressor (12) operated by a motor (11) using a driver's seat (2), an engine room, and other suitable space of the excavator (1).

The air compressor 12 is connected to the battery 3 of the excavator 1 to supply power, and configured the operation switch 13 in a position where the driver inside the driver's seat 2 is easy to operate.

The control of the operation of the air compressor 12 can be controlled manually using the operation switch 13, but can also be controlled automatically by measuring the pressure of the space in which the air is stored, that is, the pressure is less than the prescribed level If it is lowered to the air compressor 12 is to operate automatically.

An injection connector 14 and an outlet connector 15 were configured in the 1 boom 10 connected to the main body of the excavator 1 so as to be connected to the internal space 10 ', and a drain valve 16 was formed at the lower end thereof. In addition, the pressure gauge 17 and the safety valve 18 is automatically configured to open when the pressure exceeds the prescribed pressure.

The injection hose 19 is connected between the injection connector 14 and the air compressor 12 so that the compressed air of the air compressor 12 is stored in the internal space 10 ′ of the one boom 10.

In addition, the driver's seat connection connector 21 is installed in the driver's seat 2 by branching from the injection hose 19 or branching from the use hose 20 connected to the discharge connector 15.

In addition, since the second boom 10a is also an empty and closed space, when the connection hose 22 is connected, a wider storage space is secured.

In the drawings, reference numeral 4 denotes an engine compartment, 5 denotes a track wheel, and 6 denotes a bucket.

Looking at the operation of the present invention having such a configuration in detail as follows.

Excavator 1 according to the present invention is the power of the battery 3 is transmitted to the motor 11 to operate the air compressor 12 by the operation of the operation switch 13 of the driver or automatic control of the air compressor 12 Compressed air is generated by the action to be compressed and stored in the internal space (10 ') of the one boom 10 through the injection hose 19 and the injection connector (14).

In such a state, when a tool or an air injector is connected and used through the discharge connector 15, it is possible to use as air for removing dust or foreign matter as well as cleaning or operating a tool.

Therefore, it is possible to perform all maintenance or cleaning in the place where the excavation work without the need of a separate air compressor.

Naturally, when the driver's seat connection connector 21 is used, the inside of the driver's seat 2 can be cleaned, and the pressure of the inner space 10 'of the first boom 10 is determined through the pressure gauge 17 to thereby compress the air. It can also be checked visually, and when the excessive pressure is filled, the safety valve 18 operates to automatically discharge the air to prevent excessive charging.

In addition, the water generated at the time of air compression can be discharged through the drain valve 16.

According to the present invention as described above, it is possible to store the compressed air using a boom without having a separate tank for storing the compressed air, it is possible to immediately wash, clean and maintenance at the site of the excavation work, so maintenance To save a tremendous amount of time spent on the move, and can be cleaned or washed from time to time to maintain a clean working environment.

In addition, the boom of the excavator sometimes cracks due to excessive work. If this is not detected early, the boom may be broken. According to the present invention, the leak of air can be easily detected. It is a very useful invention such that damage can be prevented.
