Operation of the present invention configured as described above will be described sequentially based on each operation order.

<Operation 1>

Figure 4 shows the operation of the input means of the present invention to move simultaneously with the operation of the breaker, the vibration of the breaker is made every time the strike of the breaker, the vibration ball (1) forming the input means of the present invention is By the same number of inertia, the breaker vibrates in the opposite direction to the vibration direction of the breaker.

As described in operation 1, the pumping shaft 5 having a shape as shown in FIG. 3B rotates the pumping shaft 5 at a constant stroke (vibration) of the breaker while lubricating oil while the pumping piston 6 is linearly reciprocated. Will be pumped.

<Action 3>

Figure 6 is a view showing a lubricating oil refilling method of the lubricating oil filling container according to the filling order. When most of the lubricating oil is consumed through the transparent filling cylinder 31, the filling cylinder is separated from the lubricating oil pump to assemble the filling connecting pipe 26 as in the filling operation 1, and suction-fills the lubricating oil as in the filling operation 2. The sucked lubricating oil (grease) is viscous and is not discharged to the bottom, and the air above the filling container is discharged to the outside as shown by the arrow of g6. At this time, the lubricant is not discharged by the structure of the packing.

After filling, the filling handle 20 is pushed and reassembled in the lubricating oil pump. At this time, even if the filling handle is pushed in, the sealing plate 17 and the packing 18 are in close contact with the suction discharge plate 23 so that the lubricant is not leaked.

As described above, when lubricating oil is supplied to the lubrication necessary point of construction equipment by using the apparatus of the present invention, it eliminates the trouble of periodically filling the lubricating oil by manpower and operates according to the vibration generated when the breaker is actually hit. Therefore, the right amount of lubricant can be supplied in a timely manner to reduce environmental pollution and extend the life of construction equipment. In addition, by using a refilling lubricant storage container (lubricating oil filling container) has a useful effect that can be lubricated at a lower cost than the system using a disposable storage container.
